Description
Technical field
The present invention relates to a kind of loading-unloading vehicle, specifically a kind of loading-unloading vehicle that is used for the middle switch of power supply-distribution system is implemented the lifting carrying.
Background technology
Mid-switch extensively applies among the 10kV and 35kV power supply-distribution system of electric system and industrial enterprise.Mid-switch places in the switch cubicle in use, and can be derived, be imported by special-purpose handcart platform.Requirement according to " power grid security production work regulation ", when mid-switch is in inspecting state, must in switch cubicle, shift out, when running into many mid-switches and need overhaul, need to fall to being placed into the maintenance position after a certain mid-switch shifts out switch cubicle by the handcart platform, utilize the handcart platform to remove to shift out other mid-switch again.There is an important operation process to be like this, mid-switch is fallen to ground or is raised on the platform.At present mid-switch is fallen to ground or be raised to rely on fully on the platform and manually carry off, carry on, the hundreds of jin because mid-switch weighs, and it does not have " assistants " position of artificial lifting, and dependence is manually carried tens switches, carry on off, labor content is big, and security risk is big.
Summary of the invention
The object of the present invention is to provide a kind of mid-switch loading-unloading vehicle, this loading-unloading vehicle can fall mid-switch or be raised on this platform from special-purpose handcart platform easily.
For achieving the above object, the present invention adopts following scheme: mid-switch loading-unloading vehicle, wheel-mounted vehicle frame is provided with hydraulic efficiency elevation structure, the bearing end of hydraulic efficiency elevation structure is connected with wheel carrier, support wheel is housed on the wheel carrier, one end of the traction belt of bearing on the support wheel is fixed with vehicle frame, the other end connects with a crane, be connected with heavy together frame on the crane, the front end of a pair of horizontal crane arm that hoist frame has is connected with hanging mechanisms, is connected with a pair of adjustable supports assembly in the bottom of hoist frame.
By such scheme as seen, hanging mechanisms are connected with special-purpose conveying hole on the mid-switch, drive crane and hoist frame, can realize mid-switch is fallen or is raised on this platform from special-purpose handcart platform by hydraulic efficiency elevation structure.
The present invention is rational in infrastructure, easy to use, and the security risk that it can reduce labor intensity greatly, increase work efficiency, also evades carrying greatly is the desirable maintenance accessory equipment of electric power maintenance department.

The specific embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3
It is the hand-hydraulic lifting mechanism that the hydraulic efficiency elevation structure that the vehicle frame 1 of wheel 9,10 is provided with is housed in the present embodiment, this hydraulic efficiency elevation structure includes some Hydraulic Elements such as hydraulic hand-pump 8, hydraulic actuating cylinder 6, fuel tank 7, hydraulic actuating cylinder 6 is vertical shape and is fixed on the vehicle frame 1, and hydraulic hand-pump 8, fuel tank 7 and other Hydraulic Elements are located on the frame.The bearing end of this hydraulic efficiency elevation structure is connected with wheel carrier, and both the piston rod front end of hydraulic actuating cylinder 6 was connected with wheel carrier 13, and support wheel 14 is housed on the wheel carrier 13, and an end of the traction belt of bearing on the support wheel 14 12 is fixed with vehicle frame 1, the other end connects with a crane 5.Described support wheel 14 is a sprocket wheel, and traction belt 12 is a messenger chain.
Be connected with heavy together 2 on the crane 5, the front end of a pair of horizontal crane arm 2a that hoist frame 2 has is connected with hanging mechanisms to be made up of coupling link 4 and hook 3, and shackle 4 passes hook 3.In addition, on vehicle frame 1, be provided with handle 11
Referring to Fig. 4
The Hydraulic Elements that have in the hand-hydraulic lifting mechanism of present embodiment include fuel tank 7, check valve 24, check valve 25, safety valve 26, reach flow regulating valve 27, the hand-hydraulic lifting mechanism of the routine that these Hydraulic Elements and hydraulic hand-pump 8, hydraulic actuating cylinder 6 connect and compose.
Referring to Fig. 3, Fig. 5
5 are connected with two stay bearing plates 22 on the crane, and 23 two rollers of roller 21 and roller are housed on each stay bearing plate 22, and the inboard of two vertical beams of vehicle frame 1 has chute 1a, and each roller 21,23 cooperates with the inwall of vertical beam upper hopper chute 1a respectively.
