Mid-set switch loading and unloading truck

Abstract

The invention discloses a mid-set switch loading and unloading truck. A hydraulic pressure elevating mechanism is arranged on a wheel-mounted automotive chassis; a wheel carrier is connected with the load bearing end of the hydraulic pressure elevating mechanism; a supporting wheel is arranged on the wheel carrier; one end of a traction belt born on the supporting wheel is fixed with the automotive chassis; the other end of the traction belt is connected with an erector; a hoist frame is connected with the elector; a hanging mechanism is connected with the front ends of a pair of horizontal-shaped erector arms arranged on the hoist frame; a pair of adjustable supporting assemblies is connected with the lower part of the hoist frame; the hanging mechanism is connected with the dedicated handling hole on the mid-set switch; the hydraulic pressure elevating mechanism drives the erector and the hoist frame to realize that the mid-set switch drops off from a dedicated handcart platform or is uplifted to the platform. The mid-set switch loading and unloading truck of the invention has reasonable structure and convenient use, can greatly lighten the labor intensity, improve the working efficiency, and can greatly avoid the safety risks of carrying, and is desired maintenance assistant equipment for electrical maintenance departments.

Description

technical field [0001] The invention relates to a loading and unloading truck, in particular to a loading and unloading truck used for lifting and transporting a central switch in a power supply and distribution system. Background technique [0002] Central switches are widely used in power systems and 10kV and 35kV power supply and distribution systems of factories and mines. The central switch is placed in the switch cabinet when in use, and can be exported and imported by a special handcart platform. According to the requirements of the "Regulations on Safe Production of Power Grids", when the central switch is in the maintenance state, it must be removed from the switch cabinet. It needs to be dropped to the maintenance position, and then use the handcart platform to remove other central switches. An important operation process is to drop the central switch to the ground or lift it to the platform like this. At present, lowering the central switch to the ground or lif...

AI Technical Summary

Problems solved by technology

At present, lowering the central switch to the ground or lifting it to the platform depends entirely on manual lifting and lifting. Since the central switch weighs hundreds of kilograms, and it does not have a "hands-on" position for manual lifting, more than a dozen switches are manually lifted. Lifting up and down, the workload is heavy, and the safety risk is big
