[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, the distributed drive structure of the rail transport vehicle for tunnel construction includes a tractor at the front end and multiple transport vehicles at the rear end, a mounting cylinder 1 for connection is arranged under each of the transport vehicles, rail wheels 2 are arranged on both sides of the mounting cylinder 1, and the rail wheels 2 are driven to rotate by the tractor, wherein a hydraulic motor 3 is arranged inside a certain part of the mounting cylinder 1, a reducer 4 is installed on the output shaft of the hydraulic motor 3, and the output shaft of the reducer 4 is used to drive the rotation of the rail wheel 2, and the diameter of the mounting cylinder 1 is smaller than the diameter of the rail wheel 2, so as to ensure that the mounting cylinder 1 will not affect the normal rotation during the rotation of the rail wheel 2.

[0020] When the traction force of the tractor is small, it is necessary to start the hydraulic motor 3 to drive the reducer 4 to rotate, and the reducer 4 causes the track wheel 2 to rotate. During the startup process, the hydraulic motor 3 provides part of the power for the tractor, which can ensure the normal operation of the transport vehicle. In this embodiment, the number of hydraulic motors 3 and reducers 4 is set to two, each corresponding to one track wheel 2.

[0021] A connecting rod 5 is provided between the two track wheels 2, and the connecting rod 5 movably penetrates the interior of the mounting tube 1. Transmission gears 6 are fixedly installed on the output shaft surface of the reducer 4 and the surface of the connecting rod 5. The two transmission gears 6 are meshed. When in use, the hydraulic motor 3 is started, thereby driving the reducer 4 to rotate, and the connecting rod 5 is driven to rotate through the transmission action of the two transmission gears 6. The track wheel 2 is rotated through the connecting action of the connecting rod 5, thereby reducing the power source and saving costs.

[0022] Two support bearings 7 are fixedly sleeved on the surface of the connecting rod 5. The support bearings 7 are fixedly installed inside the mounting tube 1. The two support bearings 7 are respectively located on both sides of the transmission gear 6. The support bearings 7 provide a certain supporting force for the connecting rod 5 to ensure the service life of the connecting rod 5.

[0023] A transverse groove 8 is provided on the surface of the mounting cylinder 1, and the outer diameter of the transmission gear 6 is adapted to the inner diameter of the mounting cylinder 1. The transmission gear 6 with a larger diameter can drive the connecting rod 5 to rotate through a larger external force. A protective cover 9 is installed on the surface of the mounting cylinder 1, and the hydraulic motor 3, the reducer 4 and one of the transmission gears 6 are installed inside the protective cover 9. The transmission gear 6 is installed inside the mounting cylinder 1 by rotation, and the rotating shaft is installed on the output shaft of the reducer 4. The farthest distance from the center of the mounting cylinder 1 to the edge of the protective cover 9 is smaller than the diameter of the track wheel 2, so as to prevent the protective cover 9 from affecting the rotation of the track wheel 2.

[0024] Arc-shaped mounting plates 10 are arranged on both sides of the protective cover 9, and the curvature of the mounting plates 10 is adapted to the curvature of the mounting tube 1. The mounting plates 10 are tightly attached to the surface of the mounting tube 1, and a plurality of bolts 12 are threadedly installed on the surface of the mounting plates 10. A plurality of thread grooves 11 are provided on the surface of the mounting tube 1, and the bolts 12 are installed inside the thread grooves 11. When installing the protective cover 9, the bolts 12 are directly aligned with the position of the thread grooves 11, and the bolts 12 are screwed into the inside of the thread grooves 11. When the hydraulic motor 3 and the reducer 4 need to be repaired, the protective cover 9 can be directly disassembled, which is very convenient.

[0025] The mounting plate 10 and the protective cover 9 are an integrated structure. A sealing gasket 13 is installed on the inner side of the mounting plate 10. The sealing gasket 13 is tightly attached to the surface of the mounting tube 1. The bolt 12 movably penetrates the surface of the sealing gasket 13. The sealing gasket 13 is a rubber gasket and therefore has a certain elasticity to ensure the tightness of the installation between the mounting plate 10 and the mounting tube 1.

[0026] It should be noted that the utility model is a distributed drive structure for rail transport vehicles for tunnel construction. When in use, when the traction force of the tractor is small, it is necessary to start the hydraulic motor 3 to drive the reducer 4 to rotate, and through the transmission action of the two transmission gears 6, drive the connecting rod 5 to rotate, and through the connection action of the connecting rod 5, the rail wheel 2 is rotated to provide part of the power for the tractor, which can ensure the normal operation of the transport vehicle. When the hydraulic motor 3 and the reducer 4 need to be repaired, the bolt 12 can be removed from the inside of the threaded groove 11.
