DETAILED DESCRIPTION

[0021] In order to make the technical solution more clear to those skilled in the art, Figure 1-5 The technical solution of the utility model is described in detail:

[0022] A platform for a vehicle articulation system comprises an articulation device 1 arranged between adjacent carriages, a plurality of base plates 2 arranged on the articulation device 1, a corner shed 3, and a gantry frame 4. The gantry frame 4 is mounted on the base plate 2 through supporting casters. During operation, it is often necessary to maintain and overhaul the articulation device 1 arranged below the base plate 2. The existing base plate 2 structure is inconvenient to operate. During maintenance, the gantry frame 4 and the base plate 2 often need to be removed. The operation is relatively low and cannot meet the needs of people for long-term use. Based on this, we have made design changes to the base plate 2 structure, enlarged the first inspection window 23, and added the second inspection window 24. The maintenance and overhaul items are designed at the first inspection port and the second inspection port, which can reduce the steps of disassembling supporting casters, platforms, etc. The base plate structure design will be described in detail below:

[0023] The bottom plate 2 includes a front bottom plate 21, a rear bottom plate 22 and a first inspection opening between the two bottom plates 2, a first inspection window 23 is installed on the first inspection opening, a side opening of the front bottom plate 21 adjacent to the compartment constitutes a second inspection opening, a second inspection window 24 is installed on the second inspection opening, the front bottom plate 21, the first inspection window 23, the rear bottom plate 22 are connected to the hinge device 1 by screws, the front bottom plate 21, the first inspection window 23, the rear bottom plate 22 are placed on the hinge device 1, and the front and rear ends of the inspection windows are supported on the hinge device 1 The area of ​​the first inspection opening accounts for more than 35% of the platform area; since the front bottom plate 21, the rear bottom plate 22, the first inspection window 23, and the second inspection window 24 are interconnected, the installation of the platform is simple and reliably supported. During operation, the first inspection window 23 and the second inspection window 24 in the platform can be opened, so that the articulated device 1 can be easily maintained without removing the entire platform; wherein, the second inspection window 24 can facilitate the inspection of the connection position between the ball joint mechanism and the front vehicle.

[0024] In order to better support the first inspection window 23, a plurality of bosses 5 are provided on the left and right sides of the hinge device 1 for supporting the first inspection window 23, which can prevent the first inspection window 23 from being suspended in the air on both sides and prevent the passengers from causing the first inspection window 23 to be deformed by force at the first inspection window 23. In detail, the interface between the front bottom plate 21 and the first inspection window 23 is placed on the boss 5 of the hinge device 1, which can prevent the cantilever of the first inspection window 23 from being too long and deformed by force; the interface between the rear bottom plate 22 and the first inspection window 23 is placed on the boss 5 of the hinge device 1, which can prevent the cantilever of the first inspection window 23 from being too long and deformed by force.

[0025] Among them, the bottom plate 2 is a detachable platform, and the front bottom plate 21, the rear bottom plate 22, and the first inspection window 23 are formed by pressing and connecting multiple profiles. The profiles are press-fitted at the crimping points, and gaps are left above and below the profile fitting points to prevent interference caused by deformation of the profiles.

[0026] In order to better disassemble the first inspection window 23, two cam structures 6 are provided on the first inspection window 23, and spring plates 7 are provided on both sides of the cam structure 6. The spring plates 7 are against the cam structure 6. Connecting rods 8 are provided at the left and right ends of the cam structure 6. A latching tongue 9 is provided at the end of the connecting rod 8. Positions corresponding to the latching tongue 9 on the front bottom plate 21 and the rear bottom plate 22 are provided with limiting holes so that the latching tongue 9 can be buckled in the limiting holes. One cam structure 6 corresponds to the front bottom plate 21, and the other cam structure 6 corresponds to the rear bottom plate 22. When working, when the cam is rotated, the spring plate 7 can be compressed to stop the rotation. , the connecting rod 8 drives the latch 9 to extend or retract; when the latch 9 is retracted, the first inspection window 23 can be removed; when the latch 9 is extended, it will extend into the limiting holes on the front bottom plate 21 and the rear bottom plate 22 respectively, connecting the front bottom plate 21 and the rear bottom plate 22. In order to protect the first inspection window and improve its service life, reinforcing plates 10 are fixedly installed on the left and right sides of the bottom of the first inspection window 23. Preferably, the reinforcing plates 10 are placed vertically to the pressing position of the first inspection window 23 profile, which can prevent the first inspection window 23 profile from cracking at the pressing position.

[0027] A step portion is formed at the contact position between the front bottom plate 21 and the rear bottom plate 22 , and a plurality of mounting holes are provided on the step portion for screw connection. Specifically, countersunk screws are used for connection.

[0028] In order to improve safety protection, the platform surface has regular patterns.

[0029] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
