Description

Technical Field

[0001] A support mechanism for assembling and welding the driver's cab of a rail vehicle according to the present utility model is applicable to auxiliary support and positioning in the assembling and welding process of driver's cab profiles, and belongs to the field of manufacturing and welding processing of rail vehicles. Background Art

[0002] With the rapid development of the industrialization of rail vehicles, the types of rail vehicle models are increasing day by day. Especially, the appearance characteristics of the driver's cab at the front of the vehicle are more and more beautiful and streamlined. The increase in the types of driver's cabs at the front of the vehicle undoubtedly requires more and more corresponding matching welding support tooling in manufacturing. At the same time, the application of aluminum alloy profiles for the car body of rail vehicles requires higher and higher precision for the assembly welding of the driver's cab frame.

[0003] At present, there are many types of driver's cabs for rail vehicles, and the internal space sizes of the driver's cabs of each vehicle model are different. For the assembly and welding of the driver's cab, more support rod-type tooling is required. How to optimize the existing support rods, realize the assembly and welding at spatial angles, improve the convenience of disassembly and assembly of the support rods, and reduce the labor intensity of workers is particularly important.

[0004] For example, the assembly and welding of the driver's cab of existing rail vehicles are generally composed of several large profile components, and the internal space structure is complex. When assembling, several ordinary support rods are used for fixation. Due to the limitation of the structure of the existing support rods, the angle of the support end cannot fit well with the profile, or a large number of support rods with different angles are made to solve the support angle problem. The increase in the number of support rods limits the working space of workers for welding operations inside the driver's cab and reduces the welding work efficiency. In addition, the ordinary support rod is fixed by an ordinary T-shaped bolt. The T-shaped bolt needs to be slid into the C-shaped chute in advance and fixed with at least 2 T-shaped bolts at the support rod end. The operation of workers is cumbersome and the workload is large. For the spatial curved surface structure of the profile frame of the driver's cab of rail vehicles, how to effectively match the spatial support requirements in the frame welding process, design a support rod with a specific structure, optimize its versatility, and reduce the operation difficulty and workload of workers is particularly urgent.

[0005] In view of this, the present application is specifically proposed. Summary of the Utility Model

[0051] Referring to Figures 1 to 4 , the embodiment of the present application provides a support mechanism for assembling and welding a rail vehicle cab, including:

[0052] Support rod body 1;

[0053] A left-handed structure 2 and a right-handed structure 3 that are telescopically arranged at both ends of the support rod body 1;

[0054] A left-side angle matching structure 41, which is connected to the left-handed structure 2;

[0055] A right-side angle matching structure 42, which is connected to the right-handed structure 3;

[0056] A left-side T-shaped pull block 5, which is used for sliding and assembling into the C-shaped chute on the surface of the left-side profile frame of the cab;

[0057] A right-side T-shaped pull block 6, which is used for sliding and assembling into the C-shaped chute 71 on the surface of the right-side profile frame 7 of the cab;

[0058] The left T-shaped pull block 5 passes through the left angle matching structure 41 and is rotatably connected to the left-handed structure 2, and the right T-shaped pull block 6 passes through the right angle matching structure 42 and is rotatably connected to the right-handed structure 3;

[0059] The left angle matching structure 41 can change its angle following the change of the angle of the C-shaped chute on the surface of the left-profile frame of the cab relative to the horizontal plane;

[0060] The right angle matching structure 42 can change its angle following the change of the angle of the C-shaped chute 71 on the surface of the right-profile frame 7 of the cab relative to the horizontal plane.

[0061] By making the left angle matching structure 41 and the right angle matching structure 42 change their angles, the spatial angles of the support mechanism and the C-shaped chutes on the profile frames of the cabs of different track products are matched; in addition, by using the retractable left-handed structure 2 and right-handed structure 3, the installation of the support mechanism between the two opposite profile frames of different track products is realized.

[0062] In the embodiment of the present application, the support rod body 1 is a carbon steel round pipe with a diameter of 50 mm and a wall thickness of 5 mm, and Tr30-6 wire sleeves are welded at both ends, specifically a left-handed trapezoidal thread sleeve and a right-handed trapezoidal thread sleeve, for connecting the left-handed structure 2 and the right-handed structure 3.

[0063] The left angle matching structure 41 and the right angle matching structure 42 provided at both ends of the support rod body 1 can enable the entire support mechanism to extend or shorten synchronously towards both ends.

[0064] In order to realize the installation of the support mechanism between the two opposite profile frames 7 of different track products, the left-handed structure 2 in the embodiment of the present application includes: a first connecting rod and a first connecting plate;

[0065] The first connecting rod is screwed to the left end of the support rod body 1, and a first trapezoidal nut is used for screwing and locking to fix the first connecting plate and the first connecting rod by welding.

[0066] Refer to Figure 2 、 Figure 3 and Figure 4 , the right-handed structure 3 includes: a second connecting rod 31 and a second connecting plate 32;

[0067] The second connecting rod 31 is screwed to the right end of the support rod body 1, and a second trapezoidal nut 8 is used for screwing and locking; the second connecting plate 32 and the second connecting rod 31 are fixed by welding.

[0068] By rotating to adjust the length of the first connecting rod relative to the left end of the support rod body 1, the length adjustment of the left end of the support mechanism is achieved; by rotating to adjust the length of the second connecting rod 31 relative to the right end of the support rod body 1, the length adjustment of the right end of the support mechanism is achieved. In the embodiment of the present application, the telescopic of the support mechanism can be realized within 0-400 mm according to needs, which can cope with the spatial support widths of different cab profiles 7, and the length value can be locked by cooperating with the trapezoidal nut 8.

[0069] In the embodiment of the present application, the left-side angle matching structure 41 includes: a first lever, a first double connecting rod, a first pressing plate and a first special-shaped tightening screw;

[0070] The first lever is rotatably connected to the left-handed structure 2;

[0071] One end of the first double connecting rod is rotatably connected to the first lever, and the other end is rotatably connected to one end of the first pressing plate;

[0072] One end of the first special-shaped tightening screw is fixedly locked with the first lever, and the other end abuts against the other end of the first pressing plate;

[0073] By adjusting the assembly position of the first special-shaped tightening screw and the first lever, the angle of the first pressing plate is adjusted;

[0074] The left-side T-shaped pull block 5 passes through the first pressing plate and is rotatably connected to the first connecting plate of the left-handed structure 2; the first connecting plate is rotatably connected to the first lever.

[0075] The first lever, the first double connecting rod and the first pressing plate form the left-side three-link mechanism 41.

[0076] Refer to Figures 2 to 4 , the right-side angle matching structure 42 includes: a second lever 421, a second double connecting rod 422, a second pressing plate 423 and a second special-shaped tightening screw 424;

[0077] The second lever 421 is rotatably connected to the right-handed structure 3;

[0078] One end of the second double connecting rod 422 is rotatably connected to the second lever 421, and the other end is rotatably connected to one end of the second pressing plate 423;

[0079] One end of the second special-shaped tightening screw 424 is fixedly locked with the second lever 421, and the other end abuts against the other end of the second pressing plate 423;

[0080] By adjusting the assembly position of the second special-shaped tightening screw 424 and the second lever 421, the angle of the second pressing plate 423 is adjusted;

[0081] After the right T-shaped pulling block 6 passes through the second pressing plate 423, it is rotatably connected to the second connecting plate 32 in the right-handed structure 3; the second connecting plate 32 is rotatably connected to the second lever 421.

[0082] The second lever 421, the second double connecting rod 422, and the second pressing plate 423 form the right three-link structure 42.

[0083] The installation process of the support mechanism on the cab profile frame is fast and convenient. After the T-shaped pulling blocks at both ends of the support mechanism slide into the C-shaped chute of the profile, only the tightening force of one special-shaped tightening screw at each end is required to install it firmly.

[0084] Taking the right-angle matching structure 42 as an example, according to the spatial angle of the C-shaped chute 71 on the cab profile frame 7 of different products, the assembly position of the second special-shaped tightening screw 424 on the lever is adjusted, so that the length of the second special-shaped tightening screw 424 extending out of the second lever 421 changes. The second special-shaped tightening screw 424 then drives the second pressing plate 423 to rotate at an angle, so as to match the spatial angle requirement of the C-shaped chute 71 on the cab profile frame of the product; that is, the angle of the second pressing plate 423 can follow the angle of the C-shaped chute 71, and its versatility and adaptability are strong. At the same time, combined with the principle of the four-bar mechanism, when the support angle of the second pressing plate 423 changes, the second double connecting rod 422 and the second lever 421 connected to the second pressing plate 423 will also change their positions correspondingly. Thus, the support mechanism can adjust the support angle according to the spatial angle of the cab profile frame 7, and the support mechanism can also cope with the follow-up support at different angles at both ends at the same time.

[0085] Through the above operations, the support positioning requirements for welding the cab aluminum profile frames with various structures and angles are realized.

[0086] As described above, combined with the content of the solutions given in the drawings and embodiments, similar technical solutions can be derived. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solutions of the present invention still fall within the scope of the technical solutions of the present invention.
