There are four installation forms of lifting weight limiter: hook type, wire rope type, bearing type and fixed pulley type.
1. Hook type installation form. The product structure of the hook type installation form has three types: direct display type, FM launch type and separate type. The direct display type is used for nickel-cadmium batteries as the power source, and the hook, sensor, and large-screen display are integrated into a crane hook. The FM transmitter also uses the nickel-cadmium battery as the main power source, but there is no display part. Instead, the sensor signal is sent to the driver's cab after frequency modulation, and the signal is restored by the secondary instrument for control and display. These two types of sensors do not need to be connected to the secondary instrument with cables, but the price is higher. The separated type transmits the sensor signal to the secondary instrument through the cable, and controls and displays after processing.
2. Wire rope tension type. Use a special fixture to install the sensor on the lifting wire rope, and measure the tension of the wire rope to reflect the load. This method is easy to install and has high detection accuracy.
3. Bearing seat type. Bearing seat mounting type sensor adopts double shear beam type or cylindrical shape, with special accessories to form a bearing seat, which is installed on the non-reducer side of the wire rope drum. This type of device is convenient, easy to maintain, and has high accuracy.
4. Fixed pulley type. There are two specific installation forms for the fixed pulley type. One is to configure a set of pallet brackets to slightly lift the fixed pulley shaft, so that the sensor mounted on the bracket bears the load; the other is to control the fixed pulley shaft, press the sensor into one end of the shaft, and use this when installing The root shaft can be replaced with the original pulley shaft.
1. Safety inspection of the track: check the track, bolts and splints for cracks, looseness and corrosion. If cracks are found, they should be replaced in time, and if there are other defects, they should be repaired in time. The main inspection tool is a line track flaw detector.
2. Track measurement and adjustment:
(1) La linealidad de la pista puede ser comprobada mediante el dibujo de un cable de acero, es decir, un 0,5 mm de alambre de acero se tira en los dos engranajes de la pista y, a continuación, medido punto por punto por el método de la plomada de martillo. El intervalo entre los puntos de medición puede ser de unos 2m. .
(2) La elevación de la pista puede ser medido con un nivel de burbuja.
(3) La duración de la pista puede ser marcada con una cinta métrica de acero o de infrarrojos instrumento de medición. La desviación permitida de la grúa puente medidor es de ±5mm; la inclinación longitudinal de la pista es 1/1500, y la desviación permitida de la elevación relativa de las dos vías es de 10mm.
(4) realizar un Seguimiento de las articulaciones, la pista puede ser hecho en un directo de cabeza o de 45° de ángulo de la articulación. El oblicuo de la articulación puede hacer que la rueda de la transición sin problemas en la articulación. En general, la brecha de la articulación es de 1~2 mm, y la influencia de la temperatura en el espacio debe ser considerado en las zonas frías, generalmente 4~6mm. La diferencia de altura entre los dos rieles en la articulación, que no deberá ser mayor de 1mm.
