The top of lifting seat 20 is detachably connected with coupling assembling 12, and the bottom of lifting seat 20 is provided with lifts by crane connection structure 21.
Through the above technical scheme, when the vehicle needs to be lifted by using the jack and the like, the lifting seat 20 can be disassembled, so that the supporting plate 11 is not blocked by the lifting seat 20 below the lifting seat, the supporting plate 11 of the saddle 10 is used as a supporting point, and the jack and the like are propped against the supporting plate 11; when it is desired to hoist a vehicle using an external hoisting device, the top of the hoisting base 20 may be connected to the connection assembly, and the sling or hook of the hoist may be connected to the hoisting connection structure 21, so that the vehicle body may be hoisted by the hoisting device.

The conventional diamond plate type saddle 10 can only be used for hoisting a vehicle body in a gantry type in the process of hoisting the vehicle, but the gantry type hoisting vehicle body has more defects, such as: the gantry type hoisting is double-point hoisting, and two hoisting devices are required to synchronously operate; the gantry type hoisting structure 100 is complex, cannot be fixed with a vehicle body, and can only be used for vertical hoisting; moreover, the gantry type hoisting volume, weight and occupied area are large, and the storage and transportation are not facilitated.
In order to solve the above-mentioned problem, in an embodiment of the present application, fig. 4 is a schematic structural diagram of a lifting seat 20 provided in an embodiment of the present application, and as shown in fig. 4, the lifting seat 20 includes a lifting member 22 for connecting with a sling in an external lifting device and a pair of guard plates 23 disposed opposite to each other at intervals, and the lifting member 22 is detachably connected between the pair of guard plates 23.

The lifting structure 100 can be applied to frame-type lifting by providing the lifting member 22 connected between the pair of guard plates 23, and the flexible hanging strip of frame-type lifting is convenient to wind on the lifting member 22, or the lifting member 22 is simultaneously penetrated on the lower end of the hanging strip and the guard plates 23, so that the hanging strip and the lifting seat 20 are connected with each other. Therefore, the hoisting structure 100 in the application can be applied to frame type hoisting, and the frame type hoisting is stable, high in safety, and capable of realizing stable hoisting of single hoisting equipment, and high in universalization degree, so that the rail vehicle is conveniently hoisted.
Fig. 6 is a partial schematic view of the lifting seat 20 provided in the embodiment of the present application, in which the side wall 2 is shown, and as shown in fig. 6, the middle part of the side wall 2 of the conventional vehicle body may bulge outwards, and the part with the largest width of the whole vehicle body may be located in the middle part of the side wall 2 in the height direction. If the hanging strip is directly connected with the lifting point below the underframe, the hanging strip possibly abuts against the side wall 2, friction can be generated between the hanging strip and the side wall 2 during lifting, and the side wall 2 is affected.
In order to reduce contact between the sling and the side wall 2 of the vehicle body during lifting, fig. 5 is a schematic side view of the lifting seat 20 provided in this embodiment of the present application, and as shown in fig. 4 and fig. 5, each guard plate 23 includes a first connection portion 231 and a second connection portion 232 that are connected.

"exterior" refers to the outside of the vehicle body.
Because the second connecting portion 232 extends towards the outside of the vehicle body, the lifting piece 22 can be exposed to the vehicle body, so that the lifting belt can be spaced apart from the side wall 2 in the width direction, and when the lifting belt is lifted, the bottom end of the lifting belt is connected with the exposed lifting piece 22, so that the lifting belt is far away from the side wall 2 of the vehicle body, and the contact between the lifting belt and the vehicle body is avoided.
Alternatively, the bending angle between the first connection portion 231 and the second connection portion 232 is 90 °. The guard plate 23 is an integrally formed structure.
Alternatively, as shown in fig. 4 and 5, the lower edge of the guard plate 23 is arc-shaped, and the edges of the two ends of the guard plate 23 also adopt arc-shaped contours, and the edges of the whole guard plate 23 adopt smooth lines, so that abrasion of the suspender when the guard plate 23 rubs with the suspender can be reduced.
In order to strengthen the lifting seat 20, in one embodiment of the present application, as shown in fig. 4, the lifting seat 20 further includes a first reinforcing member 24, two ends of the first reinforcing member 24 overlap the top surfaces of the two second connecting portions 232, respectively, the first reinforcing member 24 is sandwiched between the second connecting portions 232 and the supporting plate 11, and the top surface of the first reinforcing member 24 abuts against the supporting plate 11.
The provision of the first reinforcement 24 between the pair of the guard plates 23 contributes to an increase in the force transmission between the two guard plates 23, and increases the strength of the entire lifting seat 20, and the top surface of the first reinforcement 24 is abutted against the support plate 11, thereby increasing the contact area between the lifting seat 20 and the frame saddle 10, and the force is transmitted to the frame saddle 10 and further to the underframe through the guard plates 23, thereby contributing to the force transmission between the two and contributing to the dispersion of the force. In addition, when the lift is lifted, the lift base 20 can firmly abut against the saddle 10 through the first reinforcing member 24, and the shaking is not easy to occur.
To further strengthen the lifting foot 20, in one embodiment of the present application, as shown in fig. 4, the lifting foot 20 further comprises a second reinforcement 25. The second reinforcement 25 and the first reinforcement 24 are arranged at intervals, two ends of the second reinforcement 25 are respectively connected with bottoms of the two second connecting portions 232, and the first reinforcement 24 and the second reinforcement 25 are respectively connected with the upper portion and the lower portion of the guard plate 23, so that the lifting seat 20 forms a box-shaped structure, the second reinforcement 25 can further increase the connection between the two guard plates 23, and the integral strength of the lifting seat 20 is increased.
The specific structure of the connection assembly 12 is not limited in this application, and the saddle 10 may be fixed under the underframe by the connection assembly 12.
