Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] Please see Figures 1 to 3 This embodiment provides an auxiliary device for installing rail vehicle components, including a fixed plate 1, a lifting platform 2, a sliding rod 3, a first mounting plate 4, a second mounting plate 5, and a rotating mounting plate 6.

[0024] The fixed end of the lifting platform 2 is fixed to the fixed plate 1. The lifting platform 2 and the fixed plate 1 can be connected by welding, riveting, bolting or other methods. The bottom end of the fixed plate 1 is connected to a roller, which can facilitate the movement of the fixed plate 1. A moving handle is connected to one end of the lifting platform 2, which can be easily held by the staff to push the lifting platform 2 and the fixed plate 1 to move.

[0025] The sliding rod 3 is set horizontally, with one end fixedly connected to the drive end of the elevator 2. The sliding rod 3 and the elevator 2 can be connected by welding, riveting, bolting or other methods.

[0026] The first mounting plate 4 and the sliding rod 3 are slidably connected along a first direction, which is generally horizontal. Specifically, the rail vehicle component installation auxiliary device also includes multiple sliding sleeves 7. The first mounting plate 4 is fixedly connected to the multiple sliding sleeves 7, and the sliding sleeves 7 are sleeved on the sliding rod 3 and slidably connected to the sliding rod 3. More preferably, the sliding sleeves 7 and the sliding rod 3 have circular cross-sections. More preferably, there are two sliding rods 3, which are arranged in parallel and correspond to the two ends of the first mounting plate 4 respectively. The first mounting plate 4 and the sliding rod 3 are slidably connected by the sliding sleeves 7.

[0027] Preferably, the auxiliary device for installing rail vehicle components further includes a positioning bolt 8, which is threadedly connected to the sliding sleeve 7 and abuts against the surface of the sliding rod 3. When the positioning bolt 8 is tightened, it abuts against the sliding rod 3, thus fixing the sliding sleeve 7 to the sliding rod 3. When the positioning bolt 8 is loosened, it disengages from the sliding rod 3, at which point the sliding sleeve 7 can slide along the sliding rod 3.

[0028] Preferably, the auxiliary device for installing rail vehicle components further includes a limiting sleeve 9, which is threadedly connected to the end of the sliding rod 3 away from the elevator 2, and protrudes from the surface of the sliding rod 3. The function of the limiting sleeve 9 is to prevent the sliding sleeve 7 from sliding out from one end of the sliding rod 3.

[0029] The second mounting plate 5 is slidably connected to the first mounting plate 4 along the second direction. The second direction is intersected with the first direction. Preferably, the second direction is generally horizontal and perpendicular to the first direction, so that the adjustment of each direction will not affect each other.

[0030] The rotating mounting plate 6 is disposed on the upper side of the second mounting plate 5 and is rotatably connected to the second mounting plate 5. Specifically, the surface of the second mounting plate 5 has a raised annular abutment boss 5b, and the bottom side of the rotating mounting plate 6 has an annular abutment groove 6a. The abutment boss 5b and the abutment groove 6a are connected in a mating manner. The mating of the annular abutment boss 5b and the abutment groove 6a allows the rotating mounting plate 6 to rotate on the second mounting plate 5. The contact surfaces of the abutment boss 5b and the abutment groove 6a have a certain slope to increase the contact area between the two. Generally, lubricant is filled in the contact gap between the two to reduce friction. A larger area can accommodate more lubricant.

[0031] Preferably, the auxiliary device for installing rail vehicle components further includes multiple linear slide rails 10, which are parallel and arranged along the second direction and fixedly connected to the first mounting plate 4. The linear slide rails 10 and the first mounting plate 4 can be connected by welding, riveting, bolting or other methods. The second mounting plate 5 has multiple sliding grooves 5a, which correspond one-to-one with the multiple linear slide rails 10 and are slidably connected.

[0032] Preferably, the rail vehicle component installation auxiliary device further includes multiple limiting pins 11, which are connected to the first mounting plate 4 and used to restrict the movement of the second mounting plate 5. When the second mounting plate 5 moves to the limit position, it will abut against the limiting pins 11.

[0033] Preferably, the rail vehicle component installation auxiliary device further includes a gear 12, a rack 13, and a rotating handle 14. The gear 12 is fixedly connected to the rotating handle 14 and rotatably connected to the second mounting plate 5. The rack 13 is arranged along the second direction and fixed to the first mounting plate 4, and meshes with the second mounting plate 5. Rotating the rotating handle 14 drives the gear 12 to rotate, thus the second mounting plate 5 moves along the rack 13. Since the components carried on the rotating mounting plate 6 are relatively heavy, moving the components by rotating the handle 14 is more labor-saving.

[0034] In summary, the rail vehicle component installation auxiliary device provided in this application allows for the following steps: First, the lifting platform 2 is raised or lowered so that the height of the component on the rotating mounting frame is close to the installation height. Then, the first mounting plate 4 is slid to bring the component's position in the first direction close to the installation position. Next, the second mounting plate 5 is slid to bring the component's position in the second direction close to the installation position. The rotating mounting frame can be rotated to bring the component to the desired installation angle. By repeating the above adjustments, the component can be adjusted to the installation position. The adjustment range is large and accurate, and the device is easy to use.

[0035] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
