The utility model determines that the surface size of the platform 4 is 60cm*50cm according to the national standard size of the switch cabinet door and the circuit breaker. Since the circuit breaker is installed on a fixed crossbeam 80 cm away from the cabinet door, the platform 4 carrying the circuit breaker needs to extend into the cabinet at 80 cm. In order to determine the length of the L-shaped bracket 21 of the carrying platform 4 and the height of the rear seat 22 For the optimal value, multiple sets of data simulations are carried out in this embodiment, and the results are shown in Table 1 and Table 2.

L-shaped bracket length (cm) Test status 80 The length is enough to send the circuit breaker to the installation, but there is no installation margin 100 The circuit breaker can be sent to the installation place conveniently, and there is an installation margin 120 Too long, inconvenient to operate

Table 1

Table 2

n in Table 2 represents the highest height that the platform 4 needs to be raised.

Through Table 1 and Table 2, it is finally determined that the length of the L-shaped bracket 21 is 100 cm, and the height of the rear seat 22 is 50 cm.

Considering that the weight of the circuit breaker is about 200 kilograms, considering the safety, leverage principle and margin issues, the foot-operated hydraulic jack 3 and the chain 32 with a load capacity of 5 tons were finally used, and the cylinder of the foot-operated hydraulic jack 3 Total height is 98cm, and chain 32 is long 100cm. Considering the length of the chain 32, it is determined that the middle crossbeam of the car body 1 is set close to the upper part of the oil cylinder block, and the vertical distance from the ground is 98cm; and considering that the platform 4 needs to reach 140cm when it is the highest during the operation process, according to the lifting speed and the oil cylinder The ratio is 2:1, and the platform 4 is 20cm above the ground at the lowest point, so the pedal hydraulic jack 3 needs to be raised by 60cm.
