Foundation construction is the key link in crane installation. Before the foundation construction, a detailed site survey needs to be carried out according to the design drawings to ensure that the construction environment meets the design requirements. During the excavation of the foundation, the depth and size of the excavation need to be precisely controlled to avoid damage to the foundation. The foundation needs to be poured with high-strength concrete to ensure its strength and stability. During the pouring process, care should be taken to control the uniformity and compactness of the concrete to prevent voids and cracks. After the concrete pouring is completed, appropriate maintenance work must be carried out to ensure that the strength and stability of the foundation meet the design requirements. At the same time, the installation of embedded parts is also an important part of the foundation construction. The location, size and elevation of the embedded parts must be installed in strict accordance with the design requirements. During the installation of embedded parts, effective fixing measures need to be taken to ensure that they will not move or deform due to vibration or external forces during construction. The surface of the embedded parts should be rust-proof to extend their service life. Basic construction and installation of embedded parts are the basic work of crane installation, which provides a solid foundation for subsequent crane installation.
The assembly of the main beam and end beam is one of the important links in the installation of the crane. During the assembly process, high-strength bolts need to be used to connect the components together to ensure the firmness and tightness of the connection. At the same time, the connection parts also need to be anticorrosive to extend the service life of the equipment. The parallelism and verticality of the main beam and end beam are the key factors to ensure the stability and operating accuracy of the crane. During the assembly process, measuring instruments should be used for accurate measurement and calibration to ensure that the parameters meet the design requirements. If any deviations are found, adjustments must be made in time to ensure the normal operation and safety of the crane.
The installation of lifting mechanism and operating mechanism is the core link of crane installation. During the installation process, it is necessary to operate in strict accordance with the design requirements. For key components such as motors, reducers, and brakes in the lifting mechanism and operating mechanism, detailed inspection and debugging are required to ensure their good performance. Especially for wearing parts such as transmission chains and wire ropes, preload and adjustment are required to improve the reliability and service life of the equipment. In addition, the appearance of the equipment needs to be checked to ensure that it is neat and intact. During the inspection process, if any problems are found, they must be dealt with in time to ensure the normal operation and safe use of the equipment.
The installation of safety devices is an important guarantee to ensure the safe operation of the crane. During the installation process, the design requirements must be strictly followed for operation. Critical safety devices such as limit switches, overload protection devices, and emergency stop buttons need to be sensitive and reliable; the installation of electrical systems needs to follow relevant electrical safety regulations for wiring, wiring, and insulation testing; necessary grounding protection treatment for electrical systems to prevent accidents caused by leakage and other reasons.; After the installation is completed, the overall equipment needs to be debugged and operated to test whether its performance indicators meet the design requirements and standards; if a problem is found, it needs to be adjusted and dealt with in time until the equipment fully meets the requirements for use before it can be put into normal use.
During the construction process, the principle of production safety must always be adhered to, and construction safety is given the first priority. To this end, a series of safety rules and regulations should be established and strictly enforced to ensure that every aspect of the construction site is under strict control. In the infrastructure of the construction site, eye-catching safety warning signs should be set up, such as no fireworks, beware of falling, etc., in order to remind construction workers and passers-by to pay attention to safety. At the same time, construction workers must properly wear safety protection equipment, such as helmets, protective glasses, gloves, etc., to reduce the risk of accidental injury. In order to identify and solve potential safety hazards in a timely manner, it is also necessary to carry out regular safety inspections and conduct a comprehensive check of the construction site to ensure that nothing is left out.
The development of emergency plans and drills are equally important. For possible emergencies, such as fires and accidents, detailed emergency plans should be made in advance to clarify the emergency organization, rescue procedures and division of responsibilities. In order to ensure the effectiveness of the plan, simulation drills should also be carried out regularly to improve the emergency response capability, so that the construction personnel can quickly and accurately take countermeasures in the face of emergencies.
Construction quality control is a key link to ensure the performance of the crane. In the construction process, quality control must be carried out in strict accordance with the design requirements and relevant standards. In order to ensure the construction quality and accuracy, it is necessary to set up inspection points at key nodes and carry out process inspection and final inspection. Process inspection includes sampling and monitoring of key processes during construction to ensure that the construction quality and accuracy meet the design requirements. The final inspection is a comprehensive inspection after the completion of construction to ensure that the entire construction process meets the design requirements and standards.
In addition to conventional inspection methods, non-destructive testing is also required for key components. Commonly used non-destructive testing methods include ultrasonic testing, magnetic particle testing and so on. These methods can detect potential defects and problems to ensure the quality and safety of critical components. Through the implementation of these measures, it can ensure that the performance and quality of the crane meet the design requirements and relevant standards
When making the construction progress plan, it is necessary to give full consideration to the crane installation requirements, construction conditions and various delay factors that may occur. First of all, according to the crane installation process and construction specifications, the entire installation process is divided into a number of stages, such as foundation construction, equipment entry, lifting in place, electrical connections and so on. Set a specific task list for each stage, including work content, project volume, technical requirements, etc., and set a reasonable time node. Clarify the connection relationship between each stage to ensure the continuity and efficiency of the construction process and avoid the subsequent work being blocked due to time delay. Evaluate possible risks, such as weather changes, equipment failure, personnel quality and other factors that may lead to schedule delays, and formulate appropriate preventive measures and contingency plans for these risks.
Reasonably arrange the deployment of human resources and materials according to the construction progress plan. Ensure that the number of personnel and skill level of the construction team meet the construction demand, and carry out scientific inventory management of materials to avoid waste and shortage. Make a plan in advance for the possible shortage of resources and take various ways to ensure the timely supply of resources.
After the construction is completed, it is crucial to carry out a comprehensive and detailed acceptance of the crane. The acceptance process follows the relevant technical standards of the country and the industry, and the requirements of the design drawings, construction programs and product specifications, such as item by item for detailed inspection and testing. Appearance inspection includes, but is not limited to, whether the structural parts are deformed and damaged, whether the welds are even and firm, and whether the painting is in accordance with the specifications, etc.; the performance test covers the sensitivity and stability of the crane's lifting, descending, running, stopping and other actions, as well as the load carrying capacity, speed control and other key performance indicators; and the inspection of safety devices involves the validity verification of the limit switches, overload protection, anti-tipping protection and other safety facilities.
Acceptance process, need to operate in strict accordance with the relevant norms and standards, and detailed records of the acceptance data, the establishment of a complete acceptance file. For the problem points that do not meet the standards or design requirements, it is necessary to timely feedback to the construction unit and carry out rectification to ensure the safe and reliable operation of the crane after it is put into use.
In order to ensure the long-term stable operation of the crane, post maintenance and maintenance plan is crucial. Develop a detailed maintenance plan, including regular inspection, cleaning, lubrication, fastening and other work, as well as the replacement and repair of wearing parts. Regular inspection can timely identify and solve potential problems, cleaning can ensure the appearance and performance of the crane, lubrication can ensure the smooth operation of the crane, and fastening can ensure the structural stability of the crane. At the same time, the establishment of equipment files to record the operating conditions and maintenance history of the equipment, in order to find and solve problems in a timely manner. Through scientific maintenance and repair, extend the service life of the crane and improve the reliability and economy of the equipment.
