[0099] It should be noted that in order to make the transport vehicle convenient to move in the plane environment, a pulley part 6 can be provided at the bottom of the main body part 1, and the structure of the pulley part 6 can adopt a universal wheel structure and has a certain supporting force;

[0100] Through the above technical solutions, the technical effects produced in the embodiments of the present application are:

[0101] The main body part 1 and the inclined plate part 2 are transported to the track by connecting the external lifting device with the lifting lug part 5 and lifting the main body part 1 and the inclined plate part 2 by the lifting device, and the groove assembly 101 at the bottom of the main body part 1 is embedded with the track, so that the working vehicle can work on the main body part 1, and the laying can be completed by only lifting the main body part 1 by the lifting device, so that the maintenance equipment can quickly pass through the track, the cost is reduced, and the use is more convenient.

[0102] Referring to the drawings Figures 3-6 In some embodiments of the present application, the flat car is a self-adjusting structure, comprising:

[0103] The main body part 1 is provided with a first driving part 7 at the bottom;

[0104] The first driving part 7 is a driving motor;

[0105] The inclined plate part 2 is arranged on both sides of the main body part 1 and is fixedly connected with the main body part 1;

[0106] The main rod part 8 is arranged at the bottom of the main body part 1 and is connected with the rotating end of the first driving part 7;

[0107] The main rod part 8 is a rotating shaft structure, and a rotating gear is arranged thereon and meshes with the output end of the first driving part 7, so that the main rod part 8 is driven to rotate by the first driving part 7;

[0108] The fixing part 9 is arranged at both ends of the main rod part 8 and has an installation cavity 901 inside;

[0109] The fixing part 9 is a fixed disc structure and has an installation cavity 901 inside;

[0110] The fixing part 9 is connected with the main rod part 8 and can rotate synchronously with the main rod part 8;

[0111] The telescopic part 10 is arranged in the installation cavity 901 of the fixing part 9 in a ring-like array and protrudes out of the fixing part 9 through the telescopic end;

[0112] The telescopic part 10 is a device that can extend and retract in length, which can adopt a structure such as a gas cylinder or a hydraulic telescopic rod;

[0113] The first elastic part 11 is arranged at the telescopic end of the telescopic part 10 and is fixedly connected with the telescopic part 10.

[0114] The first elastic part 11 is made of a flexible and elastic material, such as rubber;

[0115] ​Due to the annular array arrangement of the telescopic components 10, the first elastic components 11 are also arranged in an annular array, and in the recovery state, the first elastic components 11 are in close contact with each other to form a tire structure, and in the expanded state, there is a spacing between the first elastic components 11;

[0116] Through the above technical solutions, the technical effects produced in the embodiments of the present application are as follows:

[0117] The first driving component 7 drives the main rod component 8 to rotate, and the fixed component 9 rotates synchronously. In a flat environment, the telescopic components 10 are in an initial state (i.e., a recovery state), and the adjacent first elastic components 11 are in contact with each other to form an annular tire structure for movement. When encountering a track, the telescopic components 10 are expanded, and the first elastic components 11 are displaced, and there is a spacing between the adjacent first elastic components 11 to pass through the track and other rough environments. By using the telescopic components 10 to control the state of the first elastic components 11, the operation is more convenient. By dividing the tire into multiple parts, the spacing between the first elastic components 11 can cross the track when the tire encounters the track, and the transport vehicle remains stable.

[0118] Referring to FIG. 1, Figure 7 In some embodiments of the present application, the telescopic component 10 is a hydraulic telescopic structure, which includes:

[0119] The auxiliary body component 1001 is arranged in the mounting cavity 901 of the fixed component 9 and is fixedly connected with the mounting cavity 901;

[0120] The auxiliary body component 1001 is specifically a fixed block structure;

[0121] The oil storage component 1002 is arranged in the mounting cavity 901 of the fixed component 9 and is fixedly connected with the mounting cavity 901;

[0122] The oil storage component 1002 is specifically a storage tank, and a driving pump is arranged inside;

[0123] The oil inlet channel component 1003 is arranged inside the auxiliary body component 1001, and the oil inlet end is connected with the pipeline of the oil storage component 1002;

[0124] The oil storage component 1004 is arranged inside the auxiliary body component 1001, and the bottom is connected with the oil outlet end of the oil inlet channel component 1003;

[0125] The oil outlet channel component 1005 is arranged inside the auxiliary body component 1001, and the oil outlet end is connected with the pipeline of the oil storage component 1002, and the oil inlet end is connected with the oil storage component 1004;

[0126] The oil outlet end of the oil outlet channel component 1005 is located above the oil outlet end of the oil inlet channel component 1003.

[0127] The piston component 1006 is arranged in the oil storage chamber component 1004 and is in sliding connection with the oil storage chamber component 1004.

[0128] In order to enable the piston component 1006 to automatically move downward, an overflow pipeline can be additionally arranged in the piston component 1006.

[0129] By additionally arranging the overflow pipeline, the oil below the piston component 1006 can quickly flow out during the downward movement of the piston component 1006.

[0130] The stroke rod component 1007 is fixedly connected with the piston component 1006 at one end and is arranged to pass through the oil storage chamber component 1004 and is connected with the first elastic component 11 at the other end.

[0131] The second elastic component 1008 is arranged at the bottom of the oil storage chamber component 1004 and is connected with the piston component 1006 at one end and is connected with the bottom of the oil storage chamber component 1004 at the other end.

[0132] The second elastic component 1008 is specifically a spring structure.

[0133] Through the above technical solution, the technical effects produced in the embodiment of the application are as follows:

[0134] When the telescopic component 10 needs to be driven, the oil storage chamber component 1002 supplies oil to the oil inlet channel component 1003, the oil enters the oil storage chamber component 1004 through the oil inlet channel component 1003 and specifically enters the cavity at the bottom of the piston component 1006, when the pressure in the cavity increases, the piston component 1006 moves upward and then opens the oil inlet port of the oil outlet channel component 1005, so that the oil returns to the oil storage chamber component 1002 through the oil outlet channel component 1005, at this time, the stroke rod component 1007 is lifted under the action of the piston component 1006, so that the first elastic component 11 is displaced to complete the opening action; when the telescopic component 10 needs to be reset, the oil storage chamber component 1002 stops supplying oil to the oil inlet channel component 1003, the piston component 1006 is reset under the action of the second elastic component 1008, the oil below the piston component 1006 flows out through the overflow channel of the piston component 1006, so that the piston component 1006 is reset, and the stroke rod component 1007 and the first elastic component 11 are reset; by adopting the hydraulic mode, the telescoping process is more stable, and the movement process is not easily affected by the external environment.

[0135] Refer to the accompanying drawings Figures 8-9As shown, the fixing part 9 is provided with a guide part 12 arranged symmetrically on both sides of the telescopic part 10.

[0136] The guide part 12 comprises:

[0137] The fixing part 9 is provided with a first limiting part 1201 arranged symmetrically on both sides of the telescopic part 10.

[0138] The first limiting part 1201 has a cavity inside and a through hole at the top.

[0139] The cavity is provided with a sliding groove part 1203 arranged symmetrically inside.

[0140] The second limiting part 1202 is arranged in the cavity and extends through the through hole of the first limiting part 1201.

[0141] The second limiting part 1202 is provided with a sliding block part 1204 at one end in the cavity.

[0142] The second limiting part 1202 is fixedly connected to the first elastic part 11 at one end extending through the cavity.

[0143] The sliding block part 1204 is in sliding connection with the sliding groove part 1203.

[0144] The cavity is provided with a third elastic part 1205 at the bottom, and the two ends of the third elastic part 1205 are connected to the bottom of the cavity and the sliding block part 1204, respectively.

[0145] The third elastic part 1205 is in the form of a spring structure.

[0146] When the first elastic part 11 is opened, the first elastic part 11 drives the second limiting part 1202 to move inside the first limiting part 1201, and the sliding block part 1204 of the second limiting part 1202 moves in the sliding groove part 1203 of the first limiting part 1201; when the first elastic part 11 needs to be recovered, the second limiting part 1202 is reset under the action of the third elastic part 1205.

[0147] Through the above technical solution, the technical effects of the embodiments of the present application are as follows:

[0148] By providing the guide part 12, the first elastic part 11 can be oriented during displacement, and deviation is avoided, which prevents the first elastic part 11 from overlapping during recovery, causing the first elastic part 11 to fail to reset, and enhances the stability of the whole.
