The two-way trailer includes a trailer frame 1, a trailer driving structure 2, a driving wheel structure 3, a driven wheel structure 4 and a push-pull trolley structure 5. The driving wheel structure 3 and the driven wheel structure 4 are respectively arranged on the front side and the rear side of the trailer frame 1. The trailer driving structure 2 is arranged on the front side of the trailer frame 1. The trailer driving structure 2 is connected to the driving wheel structure 3 to drive the driving wheel structure 3 to rotate. The upper surface of the middle section of the trailer frame 1 is flush with the ground. A push-pull trolley groove perpendicular to the walking direction of the two-way trailer is provided in the middle section of the trailer frame 1. Two push-pull trolley structures 5 with opposite running directions are arranged in the push-pull trolley groove. Each push-pull trolley structure 5 includes a trolley frame 6, a trolley driving structure 7, a trolley pull block 8, a push trolley pull block 9 and a pull block toggle structure 10. A push-pull trolley track 11 is provided on both sides of the push-pull trolley groove. A plurality of trolley wheels 12 are provided on both sides of the trolley frame 6. The trolley wheels 12 on both sides are respectively matched in the trolley tracks 11 on both sides. One end of the trolley driving structure 7 is connected to the push-pull trolley groove, and the other end is connected to the bottom surface of the trolley frame 6. The pull block toggle structure 10 is arranged on the side where the two trolley frames 6 are close to each other. The trolley pull block 8 and the push trolley pull block 9 are rotatably arranged on the side where the two trolley frames 6 are away from each other. The pull block toggle structure 10 controls the trolley pull block 8 and the push trolley pull block 9 on the same side to alternately rise and fall.

[0025] In this embodiment, a kiln car is taken as an example of a transport object. In a workshop, different kilns are generally arranged in parallel, and the tracks entering and exiting different kilns are therefore also arranged in parallel. The trailer running groove is perpendicular to the parallel tracks between different kilns, and is generally arranged in the middle of the track. When the kiln car is transported by the two-way trailer provided by the utility model, the trailer driving structure 2 of the two-way trailer is started, and the trailer driving structure 2 drives the active wheel structure 3 to run on the trailer track, thereby driving the trailer frame 1 and the driven wheel structure 4 to run on the trailer track. When running to the target track position, the trailer driving structure 2 stops driving, and the two-way trailer stops running. At this time, according to the direction of the kiln car to be transported, the trolley driving structure 7 in the corresponding direction is started, and the trolley driving structure 7 drives the trolley frame 6 to extend along the trolley track 11. The trolley pull block 8 is close to the outside, and the trolley push block 9 is close to the inside. Before the trolley pull block 8 enters the bottom of the kiln car, it is in a fallen horizontal state and enters After reaching the bottom of the kiln car, the pull block 8 is controlled by the shifting structure 10 to be in a raised state at one end, and the height of the upper end of the trolley shifting block 8 is higher than the frame on the outer side of the bottom of the kiln car. At this time, the trolley frame 6 is driven to be recovered by the trolley driving structure 7, and the kiln car is pulled onto the trailer frame 1 by the trolley shifting block 8. After the kiln car is completely on and stopped, the trailer driving structure 2 of the two-way trailer is driven to drive the two-way trailer to the target transfer position through the active wheel structure 3 and the driven wheel structure 4. At this time, the trolley shifting structure 10 controls the trolley shifting block 8 to fall to a horizontal state, the trolley shifting block 9 is raised, and the trolley driving structure 7 is started again. The trolley driving structure 7 drives the trolley frame 6 to extend along the trolley track 11. During the process, the trolley shifting block 9 pushes the frame on the outer side of the bottom of the kiln car to make the kiln car go out of the two-way trailer. At this point, the kiln car is sent to the target position, and the trolley driving structure 7 drives the trolley frame 6 to be retracted along the trolley track 11, and the next round of work can be carried out. In this process, the parking of the two-way trailer at a certain position can be achieved by setting sensors through the main controller, and because the weight of the two-way trailer and the kiln car is generally large, a deceleration buffer structure can be set on the trailer frame 1 to control the kiln car to decelerate, and a parking fixed structure can be set at the bottom of the two-way trailer to control the trailer to stop at the target position.

[0026] As a specific setting method of the trolley shift block 8 and the trolley shift block 9, two shift block grooves are adjacently arranged on the upper surface of the trolley frame 6, and a shift block shaft 13 is arranged in the shift block groove. The trolley shift block 8 and the trolley shift block 9 are respectively rotatably connected to one shift block shaft 13, and the center of gravity of the trolley shift block 8 and the trolley shift block 9 are both biased to the same side of the shift block shaft 13. The shift block shifting structure 10 includes a shifting cylinder 23 and a shifting rod 24. The output end of the shifting cylinder 23 is connected to the shifting rod 24. A shifting head 25 with a trapezoidal longitudinal section is provided above the end of the shifting rod 24 away from the shifting cylinder 23. The movement range of the shifting head 25 is at least between the positions below the trolley shift block 8 and the trolley shift block 9. The two ends of the lower surface of the side where the center of gravity of the trolley shift block 8 and the trolley shift block 9 are located are inclined surfaces. When the shifting head 25 is located below the trolley shift block 8 or the trolley shift block 9, the upper surface of the trolley shift block 8 or the trolley shift block 9 is flush with the upper surface of the trolley frame 6.

[0027] During operation, if the kiln car needs to be pulled onto the two-way trailer, the oil cylinder 23 is controlled to retract the lever 24, so that the lever head 25 is pulled under the trolley lever block 9. At this time, the upper surface of the trolley lever block 9 is flush with the upper surface of the trolley frame 6, and the side where the center of gravity of the trolley lever block 8 is located falls, and the other side is tilted, so that the trolley can be pulled. If the kiln car needs to be pushed onto the two-way trailer, the oil cylinder 23 is controlled to extend the lever 24, so that the lever head 25 is extended under the trolley lever block 8. At this time, the upper surface of the trolley lever block 8 is flush with the upper surface of the trolley frame 6, and the side where the center of gravity of the trolley lever block 9 is located falls, and the other side is tilted, so that the trolley can be pushed.

[0028] Preferably, in this embodiment, the trolley driving structure 7 is a trolley driving oil cylinder, and oil cylinder connecting frames are provided in the push-pull trolley slot and on the trolley frame 6, and the two ends of the trolley driving oil cylinder are respectively connected between the two oil cylinder connecting frames. And the stop of the push-pull trolley structure 5 at a certain position is also realized by the sensing device.

[0030] When driving the bidirectional trailer to move, the trailer drive chain 15 is driven by the trailer drive motor 14 to drive the passive sprocket 17 to rotate, thereby driving the two driving wheels 16 to rotate through the driving wheel shaft 26, thereby driving the trailer frame 1 and the driven wheel structure 4 to move on the trailer track.

[0031] In order to prevent the bidirectional trailer from falling off the track, as an improvement of the technical solution, guide mechanisms are respectively provided under the left and right sides of the trailer frame 1, and the guide mechanisms include a guide frame 19 and a guide wheel 20. The guide frame 19 is fixedly connected under the trailer frame 1, and a guide wheel 20 is respectively provided on the guide frames 19 on both sides of the trailer track, and the sides of the two guide wheels 20 that are close to each other are in contact with the two sides of the trailer track.

[0032] During the operation of the bidirectional trailer, taking one side as an example, the two guide wheels 20 clamp the trailer track to prevent the trailer from deviating from the track.

[0033] In order to prevent the two-way trailer from colliding with other equipment or walls during operation, the utility model also includes an anti-collision structure for anti-collision purposes. The anti-collision structure includes an anti-collision frame 21 and a limit frame 22. The lower part of the anti-collision frame 21 is rotatably connected to the lower part of the front and rear sides of the trailer frame 1. The limit frame 22 is arranged on the outer side of the connection point between the anti-collision frame 21 and the trailer frame 1, and the end of the limit frame 22 away from the trailer frame 1 is bent upward; and proximity switches are arranged on the front and rear sides of the trailer frame 1, and the proximity switches are triggered when the anti-collision frame 21 approaches the trailer frame 1.

[0034] During normal operation, the lower end of the anti-collision frame 21 rests on the limit frame 22. When one side of the two-way trailer approaches other equipment or a wall, the upper end of the anti-collision frame 21 on that side is pushed toward the trailer frame. When it reaches a certain degree of proximity, the proximity switch senses the anti-collision frame 21 and transmits a signal to the main controller, which controls the trailer to stop and can trigger an alarm.

[0035] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
