Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology for cargo handling vehicles, and more specifically, to a gantry assembly line for cargo handling vehicles. Background Technology

[0002] Cargo handling vehicles are handling devices used to move goods. Currently, when assembling the gantry components of cargo handling vehicles, the assembly of the gantry components is completed at a fixed assembly station. Since the gantry components contain many parts, it is necessary to move all the parts to the gantry assembly station when assembling the gantry components. This has the disadvantages of being troublesome to assemble the gantry components and having a high labor intensity for the workers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a gantry assembly line for a transport vehicle, which can move the gantry assembly to different assembly stations by moving the walking component relative to the track component, that is, the gantry assembly can complete the assembly of different parts at different assembly stations.

[0004] This utility model provides a gantry assembly line for a transport vehicle, including a track assembly, a support platform, and two walking assemblies arranged symmetrically on the left and right sides. The upper ends of the two walking assemblies are respectively fixed to the bottom of the left and right ends of the support platform, and the lower ends of the two walking assemblies are connected to the track assembly and can move along the extension direction of the track assembly. The support platform is used to support the gantry assembly of the transport vehicle and to allow the gantry assembly to be assembled on the support platform.

[0005] By adopting the above structure, when the gantry assembly is assembled on the support platform, the gantry assembly can be moved to different assembly stations by the movement of the walking component relative to the track component. That is, the gantry assembly can complete the assembly of different parts at different assembly stations, so that it is not necessary to transport all the parts used for gantry assembly to the same station. This can bring convenience to the assembly of the gantry assembly and reduce the labor intensity of the workers.

[0006] In one possible implementation, two symmetrically arranged limiting plates are fixed to the top of the left end of the support platform. The two limiting plates abut against the left end of the gantry assembly to limit the gantry assembly. With this structure, under the action of the two limiting plates, when the gantry assembly is assembled on the support platform, the gantry assembly can abut against the limiting plates, thereby limiting the gantry assembly and facilitating its assembly.

[0007] In one possible implementation, two symmetrically arranged limiting blocks are fixed at the upper end of the support platform and at the middle of the left-right direction of the support platform. The two limiting blocks are used to abut against the front and rear sides of the gantry assembly to limit the front and rear movement of the gantry assembly. With this structure, under the action of the two limiting blocks, when the gantry assembly is assembled on the support platform, the front and rear sides of the gantry assembly can abut against the limiting block located on the front side of the support platform and the limiting block located on the rear side of the support platform, respectively, thereby limiting the front and rear movement of the gantry assembly to facilitate the assembly of the gantry assembly.

[0008] In one possible implementation, the track assembly includes two tracks arranged symmetrically front to back and several support plates; the support plates are all disposed at the bottom of the two tracks and are spaced apart along the length of the tracks, and each track is welded and fixed to the support plates; by adopting this structure, the support plates can reliably fix and support the two tracks, so as to ensure that the traveling assembly can reliably move on the track assembly along the extension direction of the track assembly.

[0009] In one possible implementation, a reinforcing plate is welded and fixed between the upper end face of each support plate and the outer wall of the corresponding track, and each reinforcing plate is perpendicular to the support plate and the track; by adopting this structure, the fixing strength between each track and the support plate can be further improved.

[0010] In one possible implementation, each traveling component includes a support frame; two symmetrically arranged rollers are rotatably connected to the front and rear sides of the lower end of each support frame, and each roller is rotatably connected to the corresponding side of the track; by adopting this structure, under the rolling cooperation of the rollers and the track, the support frame can reliably move relative to the track, that is, each traveling component can reliably move along the extension direction of the track, thereby ensuring that the traveling component can reliably move on the track component along the extension direction of the track component.

[0017] See Figure 1-2 As shown in the figure, this application discloses a gantry assembly line for a transport vehicle, including a track assembly 1, a support platform 2, and two walking assemblies 3 arranged symmetrically on the left and right sides. The upper ends of the two walking assemblies 3 are respectively fixed to the bottom of the left and right ends of the support platform 2, and the lower ends of the two walking assemblies 3 are connected to the track assembly 1 and can move along the extension direction of the track assembly 1. The support platform 2 is used to support the gantry assembly 4 of the transport vehicle and to allow the gantry assembly 4 to be assembled on the support platform 2.

[0018] Two limiting plates 21 are fixed to the top of the left end of the support platform 2, which are arranged symmetrically front and back. The two limiting plates 21 are used to abut against the left end of the gantry assembly 4 to limit the gantry assembly 4. With this structure, under the action of the two limiting plates, when the gantry assembly is assembled on the support platform, the gantry assembly can abut against the limiting plates, thereby limiting the gantry assembly and facilitating the assembly of the gantry assembly.

[0019] Two symmetrically arranged limiting blocks 22 are fixed at the upper end of the support platform 2 and in the middle of the left-right direction of the support platform 2. The two limiting blocks 22 are respectively used to abut against the front and rear sides of the gantry assembly 4 to achieve front-back limiting of the gantry assembly 4. With this structure, under the action of the two limiting blocks, when the gantry assembly is assembled on the support platform, the front and rear sides of the gantry assembly can abut against the limiting block located on the front side of the support platform and the limiting block located on the rear side of the support platform, respectively, thereby achieving front-back limiting of the gantry assembly to facilitate the assembly of the gantry assembly.

[0020] The track assembly 1 includes two tracks 11 arranged symmetrically front to back and several support plates 12. The support plates 12 are all located at the bottom of the two tracks 11 and are spaced apart along the length of the tracks 11. Each track 11 is welded and fixed to the support plates 12. With this structure, the support plates can reliably fix and support the two tracks, so as to ensure that the walking assembly can reliably move along the extension direction of the track assembly.

[0021] A reinforcing plate 13 is welded and fixed between the upper end face of each support plate 12 and the outer side wall of the corresponding track 11. Each reinforcing plate 13 is perpendicular to the support plate 12 and the track 11. By adopting this structure, the fixing strength between each track and the support plate can be further improved.

[0022] Each traveling component 3 includes a support frame 31; two rollers 32 arranged symmetrically on the front and rear sides of the lower end of each support frame 31 are rotatably connected, and each roller 32 can be rolled on the corresponding side of the track 11; by adopting this structure, under the rolling cooperation of the rollers and the track, the support frame can reliably move relative to the track, that is, each traveling component can reliably move along the extension direction of the track, thereby ensuring that the traveling component can reliably move on the track component along the extension direction of the track component.
