Embodiment Construction

[0016] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0017] see figure 1 , figure 2 , image 3

[0018] The hydraulic lifting mechanism provided on the vehicle frame 1 with wheels 9 and 10 in this embodiment is a manual hydraulic lifting mechanism. The hydraulic lifting mechanism includes some hydraulic components such as a manual hydraulic pump 8, a hydraulic cylinder 6, and a fuel tank 7. Cylinder 6 is vertically fixed on vehicle frame 1, and manual hydraulic pump 8, fuel tank 7 and other hydraulic components are located on the frame. The load-bearing end of this hydraulic lifting mechanism is connected with a wheel frame, and the front end of the piston rod of the hydraulic cylinder 6 is connected with a wheel frame 13, and a support wheel 14 is housed on the wheel frame 13, and one end of the traction belt 12 undertaken on the support wheel 14 is connected with the vehicle frame 1. Fixed, the other end is c...

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...
