Description

Technical Field

[0001] This utility model relates to the field of rail passenger vehicle maintenance, and in particular to a device for supporting rail passenger vehicles. Background Technology

[0002] In the daily maintenance, repair, and manufacturing of railcars, reliable support devices are essential to ensure the car's stability. Traditional railcar support devices are bulky and complex to operate. Specifically, regarding structural stability, some early support devices are prone to deformation and breakage under the long-term pressure of the railcar, not only affecting the smooth progress of maintenance work but also potentially posing serious safety threats to personnel and equipment. In terms of installation convenience, past support devices were not easy to move as a whole. Installing and disassembling support beams often involved welding or other complex and difficult-to-operate connection methods, requiring significant manpower and time, reducing work efficiency. Regarding wheel installation positioning accuracy, some support devices could cause the railcar to shift or tilt during support, affecting the accuracy of subsequent maintenance work and potentially damaging the railcar's structure. Furthermore, for different models and specifications of railcars and complex and changing working environments, previous support devices could not flexibly adjust their structure to adapt to different needs. Summary of the Invention

[0003] In view of this, the present invention aims to provide a device for supporting rail passenger cars, thereby improving the efficiency of rail passenger car maintenance or new construction and increasing operational safety.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A device for supporting a rail passenger car includes a support frame, an axle, wheels, and bolts. The support frame has a positioning plate at its bottom, and the positioning plate is connected to a hole on its upper part that allows the axle to pass through. The axle is installed in the hole of the positioning plate.

[0006] The wheel is connected to the support frame via the axle;

[0007] The support frame is provided with a bearing platform on the top left and right sides respectively. The two bearing platforms are provided with strip holes. The bearing platforms are equipped with detachable support beams through bolts and the strip holes.

[0008] Furthermore, lifting lugs are installed on both sides of the support frame, and two positioning plates form a group. A group of positioning plates is provided on the left and right sides of the bottom of the support frame.

[0009] The wheels are arranged in pairs, and each pair of wheels is mounted on the front and rear ends of a set of positioning plates via the axle, with the wheels located between the set of positioning plates.

[0010] Furthermore, the upper part of the support beam is provided with a first reinforcing plate, and the lower part of the support beam is provided with a second reinforcing plate, and the first reinforcing plate is provided with a round hole.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] The device for supporting railcars described in this utility model enhances the structural strength of the supporting beam by setting a first reinforcing plate and a second reinforcing plate at the top and bottom of the supporting beam, respectively. This allows the supporting beam to better bear the weight of the railcar. Compared with some supporting devices without such reinforcing structures, it is more stable and reliable during the support process, reducing the safety risks caused by insufficient strength of the supporting structure.

[0013] By providing lifting lugs on both sides of the support frame, the entire device can be easily moved to the designated position using lifting equipment, improving the convenience and efficiency of installation. Furthermore, the support beams are detachably installed by bolting to the slotted holes on the bearing platform. This method is simple and easy to understand, facilitating quick assembly and disassembly by workers, saving significant installation and disassembly time compared to some more complex connection methods.

[0014] By providing slotted holes on the support platform, the installation position of the support beam can be flexibly adjusted according to the actual support requirements of the railcar. Meanwhile, the circular holes on the first reinforcing plate can be used to install other auxiliary fixing components, further enhancing the device's ability to provide stable support for the railcar in different scenarios. This allows it to adapt to more complex working environments and the support needs of different railcar models, offering greater flexibility and adaptability compared to existing support devices with limited functionality.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This embodiment relates to a device for supporting rail passenger cars, which can improve the efficiency of rail passenger car overhaul or new construction and increase operational safety.

[0025] Based on the above design concept, an exemplary structure of the device supporting the rail passenger car in this embodiment is as follows: Figure 1-3 As shown, it mainly includes a support frame 1, an axle 2, a wheel 3, and bolts 10. The support frame 1 has a positioning plate 9 at its bottom, and the positioning plate 9 has holes for the axle 2 to pass through. The axle 2 is installed in the holes of the positioning plate 9. The wheel 3 is connected to the support frame 1 via the axle 2. The top left and right sides of the support frame 1 are respectively provided with load-bearing platforms 8, and the two load-bearing platforms 8 have strip-shaped holes. Specifically, as shown... Figure 3 As shown, the strip holes are located on the upper and lower sides of the upper end face of the bearing platform 8. The bearing platform 8 is equipped with a detachable support beam 4 through bolts 10 and the strip holes.

[0026] The support frame 1 is equipped with lifting lugs 5 on both sides. Two positioning plates 9 are a group. A group of positioning plates 9 are provided on the left and right sides of the bottom of the support frame 1. Two wheels 3 are a group. Each group of wheels 3 is installed at the front and rear ends of a group of positioning plates 9 through the axle 2, and the wheels 3 are located between a group of positioning plates 9.

[0027] The upper part of the support beam 4 is provided with a first reinforcing plate 6, and the lower part of the support beam 4 is provided with a second reinforcing plate 7. The first reinforcing plate 6 is provided with a round hole.

[0028] When using the device for supporting the railcar described in this embodiment, the support frame 1 is placed in a predetermined support position, and the position is further adjusted by pushing the support frame 1; alternatively, the entire device can be moved to a suitable location by using the lifting lugs 5 on both sides of the support frame 1.

[0029] Then, on the support platforms 8 on the left and right sides of the top of the support frame 1, according to the actual support requirements of the railcar 11, the support beam 4 is placed on the support platform 8. The support platform 8 has strip holes. Bolts 10 are passed through the corresponding holes on the support beam 4 and mate with the strip holes on the support platform 8, thereby detachably installing the support beam 4 on the support platform 8. The round holes on the first reinforcing plate 6 can be used in some cases to pass through other auxiliary fixing components such as ropes, to further stabilize the connection between the railcar and the support device and prevent the railcar from shifting during the support process.

[0030] Finally, the railcar 11 is lifted using lifting equipment and placed on the installed support beam 4. The support beam 4 provides stable support for the railcar 11, allowing for subsequent work such as maintenance. After the maintenance work is completed, the support device can be disassembled by reversing the steps.

[0031] The device for supporting railcars using the above-described implementation scheme significantly improves the efficiency of railcar overhaul or new construction and increases operational safety.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
