Description

Technical Field

[0001] The utility model relates to the technical field of spare parts transport vehicles, in particular to a special spare parts transport vehicle. Background Art

[0002] At present, spare parts transport vehicles used to transport parts can only transport some common parts, and cannot guarantee the quality of some parts with special requirements during transportation. For example, some parts need constant temperature and humidity conditions during transportation. For example, if they need to be transported under complex road conditions in the wild, such transport vehicles need to have the function of self-generating electricity. For example, if spare parts need to be loaded and unloaded at night in the wild, they need to have the function of night lighting. For example, when a vehicle fails and cannot be moved, it needs to have the function of landing the cabin smoothly or replacing it with another vehicle. For the transportation of these parts with special requirements, it is urgent to develop a spare parts transport vehicle with special requirements.

[0003] For this purpose we have designed a special spare parts transport vehicle. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a special spare parts transport vehicle.

[0007] Preferably, the lifting device comprises a vertically arranged screw motor, the screw portion of the screw motor is provided with a screw nut matching it, and one side of the screw nut is correspondingly connected to a support column that is movably matched with the side wall of the cabin up and down.

[0008] Preferably, a pressure detection device is provided at a position of the cabin corresponding to the sub-frame and close to the hydraulic rod.

[0009] Preferably, the bottoms of adjacent side walls of the cabin are provided with horizontal marks.

[0010] Preferably, a hydraulic rod is provided at the bottom of the sub-frame leg cross beam to assist in supporting and leveling the entire vehicle when parking.

[0011] Preferably, the front wall of the cabin is provided with a connection box having a power line interface and an oil line interface connected to the vehicle body.

[0016] It also includes a limit insertion rod radially passing through the fixed seat and the lower section of the fixed part of the lifting rod.

[0017] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0018] 1. The rotation of the lead screw part of the lead screw motor can drive the lead screw nut to descend, and then drive the support column to descend until the lower end of the support column touches the ground and the support column cannot continue to descend. At this time, the lead screw part of the lead screw motor starts to rise under the restriction of the lead screw nut, and then drives the mobile cabin to rise and separate from the sub-frame; similarly, the lifting device can also make the mobile cabin descend and place it on the top surface of the sub-frame or the ground;

[0019] 2. Before the lifting device drives the mobile cabin to rise and separate from the sub-frame, it can be known whether the lifting part of the lifting device has landed firmly according to the change of the pressure detection device, preventing the situation that the lifting part of one or some lifting devices lands weakly, resulting in the corresponding position of the mobile cabin rising later than other positions and tilting.

[0020] 3. When parking and working, the hydraulic rod can be used to assist in supporting the whole vehicle to make the whole vehicle in a horizontal state;

[0021] 4. When working at night in the wild, the height of the lighting lamp and the camera can be increased by the lifting rod.

[0037] Furthermore, the lifting rod 8 can be a hydraulic rod, an electric telescopic rod, or an artificially adjustable telescopic rod, and no specific limitation is made here.

[0038] Further, the lighting lamp 9 is designed to be a lamp that can irradiate forward or backward.

[0039] As needed, two lighting lamps 9 can be provided, one irradiating forward and one irradiating backward.

[0040] As needed, the lifting rod 8 can be rotatably connected to the shelter 3 at 180 degrees. By changing the angle of the lifting rod 8, the irradiation orientation of the lighting lamp 9 can be switched. Further, a fixed seat 31 is installed on the front wall of the shelter 3, and a circular groove 311 for embedding the lower section of the fixed part of the lifting rod 8 is provided in the middle of the top surface of the fixed seat 31;

[0041] It further includes a limit insertion rod 32 radially penetrating through the fixed seat 31 and the lower section of the fixed part of the lifting rod 8.

[0042] As needed, the fixed part of the lifting rod 8 can also be designed to be driven by a hydraulic motor to rotate 180 degrees.

[0043] Preferably, the limit insertion rod 32 can be screwed to the fixed seat 31; specifically, a fixed sleeve rotatably sleeved on the fixed part of the lifting rod 8 is further provided at the position corresponding to the upper end of the fixed part of the lifting rod 8 on the front wall of the shelter 3.

[0044] As needed, a camera 10 for photographing the surroundings of the shelter 3 is further provided on the lifting part of the lifting rod 8; when two lighting lamps 9 are provided to complete the functions of irradiating forward and backward, two cameras 10 can also be provided. When one lighting lamp 9 is provided and the lifting rod 8 is designed to be rotatably connected to the shelter 3 at 180 degrees to complete the functions of irradiating forward and backward, only one camera 10 can also be provided.

[0045] In this way, when working at night in the wild, the height of the lighting lamp 9 and the camera 10 can be increased by the lifting rod 8. The working area can be illuminated by the lighting lamp 9, and the image of the working area can be photographed by the camera 10, which is convenient for subsequent traceability work.
