Technical Field

[0001] The utility model belongs to the technical field of equipment overhaul and maintenance, and particularly relates to a valve tower overhaul vehicle. Background Art

[0002] In order to improve the utilization rate of the layout space and due to the limited space of the existing equipment room, the valve tower modules are installed in two layers, upper and lower.

[0003] Since the single-phase power supply equipment is installed in the existing equipment room and the space below 1.5 meters in the equipment room is narrow, the conventional lift truck can only move forward and backward and lift, the overhaul platform cannot rotate, and it is not easy to store and protect the valve tower module with the conventional lift truck, and it is even less convenient for the maintenance personnel to operate. Summary of the Utility Model

[0004] In order to solve the above problems in the prior art, that is, the problem that it is not easy for maintenance personnel to operate the valve tower module due to limited equipment space, the utility model provides a valve tower overhaul vehicle.

[0006] A valve tower overhaul vehicle includes a base, a hydraulic lift installed on the upper side of the base, a rotating assembly and a supporting assembly;

[0007] Walking wheels for driving the base to move are arranged on the lower side of the base;

[0008] The hydraulic lift is fixedly connected to the upper surface of the base and is arranged vertically;

[0009] The rotating assembly includes a chassis fixed to the upper end of the hydraulic lift, a rotating motor embedded in the chassis and arranged vertically upward, and a turntable fixedly connected to the rotating shaft of the rotating motor;

[0010] The supporting assembly includes a supporting platform fixedly connected to the upper side of the turntable and a supporting frame fixedly connected to the upper side of the supporting platform.

[0011] By adopting the above technical solutions, control the valve tower overhaul vehicle to move forward to the position where the valve tower module needs to be replaced, rotate the rotating rod on the base, and then make the supporting rod support on the ground to fix the position of the valve tower overhaul vehicle. Then control the hydraulic lift to start, lift the rotating assembly and the supporting assembly to the position where the supporting frame is parallel to the valve tower module, pull out the valve tower module and pull it onto the supporting frame, and the supporting frame supports the valve tower module to overhaul or replace the valve tower module. When the valve tower module is arranged on the supporting frame, the limiting assembly clamps the valve tower module to make the valve tower module more stable on the supporting frame. When the angle needs to be adjusted, only need to control the turntable of the rotating assembly to rotate to change the arrangement angle of the supporting frame.

[0012] Preferably, there are two support frames, which are divided into a first support and a second support. The first support and the second support are arranged in parallel; the first support and the second support are arranged at the middle position of the support platform.

[0013] By adopting the above technical solution, the two support frames jointly support the valve tower module, and can stably support the valve tower module.

[0014] Preferably, a limiting component is arranged on the support frame; the limiting component includes a first sub-bar. One end of the first sub-bar is rotatably connected to the lower side of the first support, and the other side is fixedly connected with a first pedal. A first clamping plate protrudes from the upper side of the first sub-bar; a first through hole is penetrated and opened on the first support. When the first sub-bar is installed on the first support, the first clamping plate is aligned with the first through hole, and when the first sub-bar rotates on the first support, the first clamping plate can be inserted into the first through hole.

[0015] A first spring is fixedly connected to the lower side of the first sub-bar. When the first sub-bar is installed on the first support, the first clamping plate is inserted into the first through hole and passes out from the other end of the first through hole. The first spring is supported on the first support, and the first spring is vertically arranged and in a balanced state.

[0016] Preferably, the limiting component further includes a second sub-bar. One end of the second sub-bar is rotatably connected to the lower side of the second support, and the other side is fixedly connected with a second pedal. A second clamping plate protrudes from the upper side of the second sub-bar; a second through hole is penetrated and opened on the second support. When the second sub-bar is installed on the second support, the second clamping plate is aligned with the second through hole, and when the second sub-bar rotates on the second support, the second clamping plate can be inserted into the second through hole.

[0017] A second spring is fixedly connected to the lower side of the second sub-bar. When the second sub-bar is installed on the second support, the second clamping plate is inserted into the second through hole and passes out from the other end of the second through hole.
