In use, the first connector 220 of the wheelbase adjustment assembly 200 moves relative to the first adjuster 210 in the direction of travel of the road wheels, depending on the model and size of the ground jack. Because the walking wheel is installed on first connecting piece 220, and at least two wheelbase adjusting part 200 set up along the direction of movement interval of walking wheel, and then can realize the distance adjustment between the first connecting piece 220 that sets up along the direction of movement of walking wheel, realize the regulation of the wheelbase of at least two walking wheels for the wheelbase between the walking wheel can adapt to ground car lifting jack, makes things convenient for subway vehicle automobile body and technology bogie to fall on ground car lifting jack, effectively improves the adaptability of framework structure 10, avoids configuring framework structure 10 of different models, effectively reduces the maintenance cost.
Further, at least two first adjusting positions 211 are formed on the first adjusting member 210 and are spaced along the moving direction of the travelling wheel, and a first mounting position 221 is formed on the first connecting member 220, and the first connecting member 220 is movable relative to the first adjusting member 210, so that the first mounting position 221 can be correspondingly connected with the at least one first adjusting position 211. By adjusting the first connecting piece 220 to move relative to the first adjusting piece 210, the first mounting position 221 is correspondingly connected with different first adjusting positions 211, so that different wheelbases of travelling wheels can be obtained, and different ground car lifting machines can be suitable. Meanwhile, due to the fact that the first adjusting positions 211 are arranged at intervals, the wheel base between each traveling wheel is adjusted by a certain size, the stepped adjustment of the wheel base between the traveling wheels is achieved, and the wheel base between the traveling wheels can be effectively corresponding to the ground car lifting jack. Meanwhile, inaccurate alignment of the travelling wheels and the ground car lifting jack caused by stepless adjustment of the wheelbase between the travelling wheels can be avoided, and adjustment difficulty and complexity are increased.
Optionally, the wheelbase adjusting assembly 200 further includes a first locking member (not shown), at least two first adjusting holes 2111 disposed at intervals are formed in the single first adjusting position 211, at least two first mounting holes 2211 disposed at intervals are formed in the first mounting position 221, the first mounting holes 2211 can be correspondingly communicated with the first adjusting holes 2111, and the first locking member is disposed in the first mounting holes 2211 and the first adjusting holes 2111 in a penetrating manner. After the first connecting piece 220 is adjusted to a proper position, the first connecting piece 220 is effectively fixed on the first adjusting piece 210 by the first locking piece, so that the travelling wheel is effectively arranged on the framework structure 10.
Specifically, the first locking member is a screw, and by using the screw, not only the reliability of the connection between the first connecting member 220 and the first adjusting member 210 can be increased, but also the first connecting member 220 and the first adjusting member 210 can be detached, so that the first connecting member 220 can be moved relative to the first adjusting member 210 conveniently.
Specifically, in this embodiment, the first adjusting position 211 is provided with two first adjusting holes 2111 disposed at intervals, and the first mounting position 221 is provided with two first mounting holes 2211 disposed at intervals. The interval between the two first mounting holes 2211 is the same as the interval between the first adjustment holes 2111 so that the first mounting holes 2211 can effectively correspond to the first adjustment holes 2111. The first connection member 220 can be effectively fixed on the first adjustment member 210 through the two first adjustment holes 2111 and the first mounting hole 2211, so that the first connection member 220 is prevented from rotating around the first locking member relative to the first adjustment member 210.
Specifically, the first adjusting hole 2111 and the first mounting hole 2211 are both straight holes, so that the first adjusting hole 2111 is effectively communicated with the first mounting hole 2211, and further machining accuracy of the first adjusting hole 2111 and the first mounting hole 2211 is reduced. Further, the length direction of the first adjusting hole 2111 is intersected with the length direction of the first mounting hole 2211, so that the first adjusting hole 2111 is easier to be correspondingly communicated with the first mounting hole 2211, and the processing precision of the first adjusting hole 2111 and the first mounting hole 2211 is further reduced.
Further, the length direction of the first adjusting hole 2111 is the axial direction of the travelling wheels, so that the stability of wheelbase adjustment between the travelling wheels is prevented from being affected when the first connecting piece 220 drives the travelling wheels to move along the length direction of the first adjusting hole 2111.
In this embodiment, the first adjusting member 210 is further formed with a first fixing portion 212, each first adjusting portion 211 corresponds to a first fixing portion 212, and a distance between each first adjusting portion 211 and the first fixing portion 212 corresponding to the first adjusting portion 211 is the same. The number of the first mounting positions 221 is two, one first mounting position 221 is correspondingly connected with the first adjusting position 211, and the other first mounting position 221 can be correspondingly connected with the first fixing position 212 corresponding to the first adjusting position 211, so that the stability of the connection between the first connecting piece 220 and the first adjusting piece 210 is further improved.
Specifically, at least two first fixing holes 2121 disposed at intervals are formed in the first fixing position 212, and a first mounting hole 2211 corresponding to the first fixing hole 2121 is formed in the other first mounting position 221. The fixing screws penetrate through the first fixing holes 2121 and the first mounting holes 2211, so that the first connecting piece 220 is effectively fixed on the first adjusting piece 210.
Further, the first fixing hole 2121 is a straight hole, which effectively reduces the machining precision of the first fixing hole 2121. Specifically, in the present embodiment, the longitudinal direction of the first fixing hole 2121 coincides with the longitudinal direction of the first adjustment hole 2111 and intersects the longitudinal direction of the first attachment hole 2211.
Specifically, the first adjusting member 210 is provided with a guide post 213, the first connecting member 220 is provided with a guide hole 222, the guide hole 222 is a linear hole, the length direction of the guide hole 222 is consistent with the moving direction of the travelling wheel, and the guide post 213 can be inserted into the guide hole 222 and move in the guide hole 222. Through guide post 213 moving in the guide way for first connecting piece 220 can effectively remove along the direction of movement of walking wheel, further improves the validity and the stability of wheelbase regulation between the walking wheel.
Further, the two first mounting locations 221 are respectively located at two opposite sides of the guide hole 222 along the length direction. The first adjusting position 211 and the first fixing position 212 are respectively located at two opposite sides of the guide post 213. Since one first mounting position 221 is correspondingly connected to the first adjusting position 211, the other first mounting position 221 is correspondingly connected to the first fixing position 212, so that the first connecting member 220 is more effectively fixed on the first adjusting member 210.
The first adjusting member 210 includes an adjusting plate 214 and a supporting plate 215, and a first adjusting hole 2111 is formed in the adjusting plate 214. The adjusting plate 214 is fixed on the frame body 100 through the supporting plate 215, so that a space is reserved between the adjusting plate 214 and the frame body 100, and a mounting space is reserved for connecting the first connecting piece 220 with the first locking piece, the fixing screw and the like of the adjusting plate 214, so that the situation that holes are formed in the frame body 100, and the first adjusting holes 2111 in the adjusting plate 214 need to be aligned with holes in the frame body 100, and the mounting difficulty of the first adjusting piece 210 is increased.
Specifically, the two support plates 215 are arranged on the adjusting plate 214 at intervals, and an accommodating space is formed by the two support plates 215 and the adjusting plate 214, so that the first locking piece, the fixing screw and the like can be conveniently installed.

The first adjusting member 210 further includes a reinforcing plate 216, one side of the reinforcing plate 216 is fixed to one support plate 215, and the opposite side is fixed to the other support plate 215. The supporting effect of the supporting plate 215 on the adjusting plate 214 can be effectively reinforced by the reinforcing plate 216. Specifically, the number of the reinforcing plates 216 is two, and the two reinforcing plates 216 are arranged at intervals. The first adjusting hole 2111 is formed on a side of the reinforcing plate 216 facing away from the other reinforcing plate 216, and the first fixing hole 2121 is formed on a side of the other reinforcing plate 216 facing away from the one reinforcing plate 216. The guide posts 213 are disposed between two reinforcing plates 216.
Of course, in other embodiments, the reinforcing plate 216 may be disposed between two adjacent first adjustment locations 211 or first fixing locations 212, so long as the supporting plate 215 is effectively supported.
The first connecting member 220 includes a pad and a connecting plate, and the first mounting hole 2211 and the guide hole 222 simultaneously penetrate the pad and the connecting plate. The connecting plate is arranged on the side of the adjusting plate 214 facing away from the supporting plate 215 through the backing plate. Specifically, the backing plate is an elastic pad.

When the first connecting piece 220 moves relative to the first adjusting piece 210, the first connecting piece 220 can effectively drive the wheel box 240 to move, and further drive the travelling wheel to move.
Further, the first connecting member 220 is provided with a fixing hole 223, and one end of the fixing member 230 passes through the wheel box 240 and is disposed in the fixing hole 223. In this embodiment, the number of the fixing members 230 is eight, each fixing member 230 corresponds to a fixing hole 223, the eight fixing members 230 are divided into two rows along the axial direction of the travelling wheel, and four fixing members 230 in each row are arranged at intervals.
