In the present embodiment, the connection mechanism 22 may be provided on the same side of the lifting mechanism 21 and the extension table 23. For example, the lifting mechanism 21 and the extension type workbench 23 are arranged on one of the front side, the rear side, the left side and the right side of the lifting mechanism 21, the lower end of the lifting mechanism 21 is fixedly connected or detachably connected with the lower end of the connecting mechanism 22, the upper end of the lifting mechanism 21 and the extension type workbench 23 are optionally in contact with the middle part of the connecting mechanism 22 and form a sliding connection at the contact part, and the extension type workbench 23 is driven to slide up and down on the connecting mechanism 22 when the lifting mechanism 21 performs lifting motion. In actual production, the mode of arrangement may be selected according to needs, and is not particularly limited herein. The lifting mechanism 21 may be provided above the extension table 23, or may be provided below the extension table 23. When the lifting mechanism 21 is disposed above the extension type workbench 23, the upper end of the lifting mechanism 21 is connected to the lower end of the traction device 1, and the lower end of the lifting mechanism 21 is connected to the extension type workbench 23, so that the connection mechanism 22 may not be required, but this way easily causes the extension type workbench 23 to be separated from the connection protection of the lifting mechanism 21 when a failure such as a breakage occurs in the lifting mechanism 21, and the extension type workbench 23 falls from the high altitude. In view of this, in the present embodiment, it is preferable that the lifting mechanism 21 is provided below the extension table 23, and the connecting mechanism 22 is provided to connect the extension table 23, the lifting mechanism 21, and the traction device 1, so that even if the lifting mechanism 21 breaks down, the extension table 23 can be hung on the connecting mechanism 22 without directly falling off, thereby further impairing the safety of the worker 200 during the inspection work and improving the safety of the inspection vehicle during use.

When the extension type work table 23 is extended and opened along the width direction of the track beam 100, the length of the extension type work table 23 is increased, and when the lifting mechanism 21 is extended to drive the extension type work table 23 to ascend, the height of the lifting mechanism 21 is increased.

Alternatively, as shown in fig. 5, the reinforcing beads 224 and the connecting plate 223 have a space therebetween in the vertical direction. Thus, when only one end of the connecting mechanism 22 is provided with the connecting plate 223 and the reinforcing rib 224, the end provided with the connecting plate 223 and the reinforcing rib 224 can be used as the lower end of the connecting mechanism 22, and when the lifting mechanism 21 and the connecting mechanism 22 are assembled, the base 211 of the lifting mechanism 21 can be clamped between the reinforcing rib 224 and the connecting plate 223, so that the reinforcing rib 224 can prevent the base 211 from moving upwards, and the connecting plate 223 can prevent the base 211 from moving downwards, thereby ensuring the firmness of the connection between the connecting mechanism 22 and the base 211; when the upper and lower ends of the connecting mechanism 22 are provided with the reinforcing ribs 224 and the connecting plates 223, it is not necessary to distinguish which end of the connecting mechanism 22 is used as the lower end to be connected with the base 211, so that the universality of the connecting mechanism 22 is improved, and the assembling efficiency is also improved.

In this embodiment, the movable platform 232 may be disposed at one end of the fixed platform 231 in the width direction of the track beam 100, or the movable platforms 232 may be disposed at both ends of the fixed platform 231 in the width direction of the track beam 100, that is, the extension type platform 23 may extend in one direction or in two directions, and in this embodiment, it is preferable that the extension type platform 23 extends in two directions to increase the operation space of the platform and facilitate the inspection of the outer side surfaces of both sides of the track beam 100. The through hole 2311 is formed in the middle of the fixing platform 231, and the connecting mechanism 22 penetrates through the extension type platform 23 at the through hole 2311, so that the extension type platform 23 is sleeved on the connecting mechanism 22, and thus, the connecting mechanism 22 can be used as a guide column to guide the lifting of the extension type platform 23, and the extension type platform 23 is prevented from shaking in the lifting process.

Alternatively, as shown in fig. 5 and fig. 6, the through hole 2311 has a first hole wall and a second hole wall opposite to each other in the width direction of the track beam 100, and a connection beam 2312 is disposed in the through hole 2311, one end of the connection beam 2312 is connected to the first hole wall, and the other end passes through the groove structure 221 and is connected to the second hole wall.

In this way, when the extension work platform 23 goes up and down, the connecting beam 2312 can go up and down in the groove structure 221, and not only can the two groove walls of the groove structure 221 located in the up-down direction be used for limiting the lifting displacement of the connecting beam 2312 and further limiting the lifting displacement of the lifting mechanism 21, but also when the lifting mechanism 21 goes wrong, the lifting mechanism 21 can be ensured to be hung at the groove structure 221 of the connecting mechanism 22 and not to directly fall off, so that the further protection effect is provided for the worker 200 standing on the extension work platform 23.

Optionally, the size of the groove structure 221 in the vertical direction is greater than or equal to the lifting stroke of the lifting mechanism 21. The lift stroke of the lift mechanism 21 is a height at which the extension table 23 is raised when the lift mechanism 21 is raised from an initial contracted state to a predetermined position. Thus, the connecting beam 2312 is prevented from being obstructed by the vertical groove walls of the groove structure 221 and cannot be lifted to a specified position, and the lifting mechanism 21 is ensured not to interfere with the vertical groove walls of the groove structure 221 after being lifted to the specified position along the connecting mechanism 22.

Optionally, the towing means 1 further comprises guiding means 15 arranged on the car body 11, the guiding means 15 being adapted to move along a side wall inside the track beam 100 for guiding the towing means 1. In this way, the guide mechanism 15 is arranged on the vehicle body 11 to guide the traveling of the traction device 1 in the track beam 100, so as to prevent the traveling mechanism 12 from deviating during the traveling process, which causes the interference between the upright body 222 of the connecting mechanism 22 and the edge of the opening at the lower end of the track beam 100; furthermore, it is not necessary to lay a guide structure such as a rail or a rail groove on the running surface of the rail beam 100 to guide the running mechanism 12, so that the change of the structure of the rail beam 100 is reduced, and the structure of the rail beam 100 is simplified.

As shown in fig. 8 to 10, when inspecting the outer side surface of the outer portion of the track beam 100, the traction device 1 drives the lifting device 2 to move to a position below a position where the outer side surface of the track beam 100 needs to be inspected, the lifting mechanism 21 drives the extension type work table 23 to rise to be close to the bottom of the track beam 100, the extension type work table 23 extends and opens along the width direction of the track beam 100, the lifting mechanism 21 drives the opened extension type work table 23 to rise until reaching the outer side of the track beam 100, and the worker 200 can inspect the outer side surface of the track beam 100 on the extension type work table 23.
