[0002] In the production activities of refractory material production enterprises, the kiln car is an important transportation equipment for transporting materials in and out of the kiln. The kiln car itself has no driving device and needs to rely on external force to send the kiln car into or out of the kiln. In addition, the kiln car needs to run on tracks during operation. Since the kiln car is usually heavy after being loaded with refractory materials, the tracks on which it runs are all straight and difficult to turn. When the kiln car needs to be transferred from one track to another, a trailer is required to assist. Therefore, the push-pull trolley of the utility model is needed to pull the kiln car out or push it into the kiln, or to pull it from the track to the trailer or push it from the trailer to the track.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] refer to Figure 1-Figure 4The utility model provides a push-pull trolley, which is arranged on the ground or on a transfer vehicle. The push-pull trolley includes a trolley frame 1, a trolley driving structure 2, a trolley pulling block 3, a trolley pushing block 4 and a block toggle structure 5. A plurality of small wheels 6 are arranged on both sides of the trolley frame 1. One end of the trolley driving structure 2 is connected to the ground or the transfer vehicle, and the other end is connected to the trolley frame 1. The block toggle structure 5 is arranged on one side of the trolley frame 1, and a trolley pulling block 7 and a trolley pushing block 8 are rotatably arranged on the other side of the trolley frame 1. The block toggle structure 5 controls the trolley pulling block 7 and the trolley pushing block 8 to alternately rise and fall on the same side.

[0019] In this embodiment, the push-pull trolley is arranged on the transfer vehicle, that is, the kiln car trailer. The kiln car is pulled onto or pushed off the trailer by the push-pull trolley provided by the utility model to realize the cross-track transfer of the kiln car. During the operation of the push-pull trolley provided by the utility model, the trolley driving structure 2 drives the trolley frame 1 to extend, the trolley pull block 7 is close to the outside, and the trolley push block 8 is close to the inside. Before the trolley pull block 7 enters the bottom of the kiln car, it is in a fallen horizontal state. After entering the bottom of the kiln car, it is controlled by the pull block toggle structure 5 to be in a raised state at one end, and the height of the upper end of the trolley pull block 7 is higher than the frame on the outside of the bottom of the kiln car. At this time, the trolley driving structure 2 drives the trolley frame 1 to be recovered, and the kiln car is pulled by the trolley pull block 7. When the kiln car is on the trailer and has completely gone up and stopped, the trailer will tow the kiln car to the target transfer position. At this time, the pull car block 7 is controlled by the shifting block toggle structure 5 to fall to a horizontal state, and the push car block 4 is raised, and the trolley driving structure 2 is started again. The trolley driving structure 2 drives the trolley frame 1 to extend out of the trailer. During the process, the push car block 8 pushes the frame on the outside 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 2 drives the trolley frame 1 to be retracted, and the next round of work can be carried out.

[0020] As a specific lifting method for the trolley shift block 7 and the trolley shift block 8, two shift block grooves are adjacently arranged on the upper surface of the trolley frame 1, and a shift block shaft 9 is arranged in the shift block groove. The trolley shift block 7 and the trolley shift block 8 are respectively rotatably connected to one shift block shaft 9, and the center of gravity of the trolley shift block 7 and the trolley shift block 8 are both biased to the same side of the shift block shaft 9. The shift block shifting structure 5 includes a shifting cylinder 10 and a shifting rod 11. The output end of the shifting cylinder 10 is connected to the shifting rod 11. A shifting head 12 with a trapezoidal longitudinal section is provided above the end of the shifting rod 11 away from the shifting cylinder 10. The movement range of the shifting head 12 is at least between the positions below the trolley shift block 7 and the trolley shift block 8. The two ends of the lower surface of the side where the center of gravity of the trolley shift block 7 and the trolley shift block 8 are located are inclined surfaces. When the shifting head 12 is located below the trolley shift block 7 or the trolley shift block 8, the upper surface of the trolley shift block 7 or the trolley shift block 8 is flush with the upper surface of the trolley frame 1.

[0021] During operation, if the kiln car needs to be pulled onto the trailer, the oil cylinder 10 is controlled to retract the lever 11, so that the lever head 12 is pulled 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 1, and the side where the center of gravity of the trolley lever block 7 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 10 is controlled to extend the lever 11, so that the lever head 12 is extended under the trolley lever block 7. At this time, the upper surface of the trolley lever block 7 is flush with the upper surface of the trolley frame 1, 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 pushed.

[0022] In order to reduce the weight of one end of the lift and to push and pull the equipment, as an improvement of the technical solution, the two sides of the pull cart block 7 and the push cart block 8 away from the end of the dial head 12 are inclined edges, and the two sides close to each other are straight edges.

[0023] For the convenience of setting, a push-pull trolley groove 13 is provided on the ground or the transfer vehicle, and push-pull trolley tracks 14 are provided on both sides of the push-pull trolley groove 13, and the several small wheels 6 on both sides of the trolley frame 1 are matched in the push-pull trolley tracks 14 on both sides.

[0024] In order to reasonably arrange the trolley driving structure 2, as an improvement of the technical solution, a first driving structure connecting bracket 3 is provided in the push-pull trolley groove 13, and a second driving structure connecting bracket 4 is provided at the bottom of the trolley frame 1, and the two ends of the trolley driving structure 2 are respectively connected between the first driving structure connecting bracket 3 and the second driving structure connecting bracket 4.

[0025] Preferably, the trolley driving structure 2 is a trolley driving cylinder.

[0026] 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.
