The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0029] Reference Figures 1 to 5The present invention discloses a peripheral dragging device, including a hoist installed in a floor shaft (not shown in the figure), the hoist includes a lifting seat, the shaft is connected to each floor, and the lifting seat can be lifted to the corresponding floor, the area outside the door of the floor is a vehicle unloading area, and also includes a dragging platform 1, a transfer rail 2, a transfer seat 3 and a transfer drive mechanism arranged on the dragging platform 1, the dragging platform 1 and the transfer rail 2 are both located in the vehicle unloading area, the dragging platforms 1 are arranged relatively, the transfer rail 2 has seven rails evenly distributed between the two dragging platforms 1, the materials on the vehicle are unloaded onto the transfer seat 3, the transfer seat 3 can move along the transfer rail 2, the transfer drive mechanism An automatic coupling and disengagement mechanism is provided between the transport seat 3 and the transfer driving mechanism, and the transfer driving mechanism can automatically connect with the transfer seat 3 through the automatic coupling and disengagement mechanism and drag the transfer seat 3 onto the lifting seat, so that the transfer seat 3 can also carry the material to the lifting seat, and the transfer driving mechanism can automatically disengage from the transfer seat 3 through the automatic coupling and disengagement mechanism. After disengagement, the elevator can lift the lifting seat and the transfer seat 3 to the designated floor, so as to store the material on the floor. Of course, the above process is also reversible, so that the stored materials can be taken out of the warehouse and transferred to the vehicle unloading area for loading and transportation. The above elevator is an existing equipment, so the specific structure and principle are not described in detail.

[0030] As shown in the figure, the transfer drive mechanism includes a transfer drive motor 4, a transfer driving sprocket 5 and a transfer driven sprocket 6 installed on the dragging platform 1. The transfer chain 7 is arranged on the transfer driving sprocket 5 and the transfer driven sprocket 6. The chain drive can withstand large pulling force and has good reliability.

[0031] As shown in the figure, the automatic coupling and disengagement mechanism includes a coupling groove 8 arranged on the transfer seat 3 and a coupling piece 9 arranged on the transfer chain 7. The coupling piece 9 can be inserted into the coupling groove 8 or disengaged from the coupling groove 8 as the transfer chain 7 moves. Because in the process of chain transmission, the chain forms a runway-shaped trajectory and moves in a closed cycle, and the trajectory includes an upper straight line, a lower straight line and arc lines at both ends. Therefore, the present application makes full use of the movement principle and structure of the chain to realize the automatic coupling and disengagement of the coupling piece 9 and the coupling groove 8. The coupling piece 9 of the present application is fixed to a certain link of the chain by screws and moves with the chain in a cycle. When the coupling piece 9 is located above the chain along the upper When moving in a straight line, the connecting piece 9 must be separated from the connecting groove 8. When connection is needed, the end of the transfer chain 7 moves to the connection position above the connecting groove 8, and then the connecting piece 9 moves obliquely downward along the arc line and can be inserted into the connecting groove 8. When the connecting piece 9 is completely inserted into the connecting groove 8, the connecting piece 9 will just move along the trajectory of the lower straight line. At this time, the connecting piece 9 will drive the transfer seat 3 to move in a straight line by engaging with the connecting groove 8 until the connecting piece 9 enters the trajectory of another arc line. At this time, the connecting piece 9 can gradually disengage from the connecting groove 8 while moving obliquely upward. After completely disengaging, the connecting piece 9 will move along the arc line and the upper straight line. As a preferred structure, the connecting groove 8 is an arc-shaped groove, and the connecting piece 9 includes an arc-shaped portion that can be inserted into the arc-shaped groove, so that it is convenient for the connecting piece 9 to be inserted into or out of the arc-shaped groove. The connecting piece 9 is fixed to a certain link of the chain by screws. As a specific structure, a connecting plate 10 is provided on the side of the transfer seat 3, and the connecting groove 8 is arranged on the connecting plate 10. In order to withstand greater force and maintain balance, a connecting piece 9 is installed on each side of the chain link. Of course, there are two connecting plates 10 relatively arranged, and there are also two connecting grooves 8 accordingly.

[0032] As shown in the figure, because there is a distance between the transfer rail 2 and the lifting seat, and after the transfer seat 3 is sent to the lifting seat and the connecting piece 9 is completely disengaged from the connecting groove 8, the end of the transfer chain 7 is still located above the transfer seat 3, and thus the connecting motor 11 drives the slide 12 to retreat a certain distance through the connecting transmission assembly, thereby completely avoiding the transfer seat 3, so that the transfer seat 3 will not collide with the transfer chain 7 during lifting. Specifically, it also includes a slide 12 and a connecting motor 11 and a guide rail assembly 13 arranged on the dragging platform 1. The slide 12 is arranged on the dragging platform 1 through the guide rail assembly 13 and the connecting motor 11 drives the slide 12 to move along the guide rail assembly 13 through the connecting transmission assembly. The transfer drive mechanism is arranged on the slide 12. Specifically: the connecting transmission assembly includes a rack 14 arranged on the slide 12 and a gear 15 arranged on the connecting motor 11, and the rack 14 is meshed with the gear 15, and the guide rail assembly 13 is a commonly used linear guide.

[0033] As shown in the figure, it also includes a positioning seat 16, on which a positioning block 17 is provided. The positioning seat 16 of the present application is arranged in the vehicle unloading area and is located at the end of the transfer rail 2. When the transfer seat 3 is located in the vehicle unloading area to load materials, the transfer seat 3 can be positioned by the restriction of the positioning block 17. The positioning block 17 is used to preferably select the rubber block.

[0034] As shown in the figure, the transfer rail 2 is provided with a guide groove 18, and the bottom of the transfer seat 3 is provided with a rotatable guide wheel 19, and the guide wheel 19 can roll in the guide groove 18. The installation structure of the guide wheel 19 is a conventional structure, so it is not described in detail. The above structure can not only guide the transfer seat 3 to move along the guide groove 18, but also facilitate the separation of the transfer seat 3 from the transfer rail 2. As a preferred structure, the bottom of the transfer seat 3 is provided with a plurality of reinforcing ribs 20, and the corresponding two reinforcing ribs 20 form a receiving groove. The guide wheel 19 is located in the receiving groove and the edge of the guide wheel 19 protrudes from the receiving groove. The above structure not only strengthens the overall strength of the transfer seat 3, but also the guide wheel 19 can make full use of the above space, thereby reducing the overall height of the transfer seat 3.

[0035] In summary, the transfer seat 3 of the present application is dragged onto the lifting seat by the transfer drive mechanism after loading materials in the vehicle unloading area, and then the transfer drive mechanism can be automatically separated from the transfer seat 3 by the automatic coupling and disengagement mechanism, and the connection motor 11 drives the slide 12 and the transfer drive mechanism on the slide 12 to retreat a certain distance through the connection transmission component, and the elevator lifts the lifting seat and the transfer seat 3 to the corresponding floor, and then the materials on the transfer seat 3 are transferred to the floor for storage, and the lifting seat drives the transfer seat 3 to descend back to the bottom floor, and the connection motor 11 drives the slide 12 and the transfer drive mechanism on the slide 12 to advance a certain distance through the connection transmission component, and the transfer drive mechanism can be connected with the transfer seat 3 by the automatic coupling and disengagement mechanism and drag the transfer seat 3 back to the loading position of the vehicle unloading area. In the above process, the transfer seat 3 is automatically connected and disengaged from the transfer drive mechanism, so as to realize the seamless connection of the transfer seat 3 from the transfer rail 2 to the lifting seat, and realize the transfer of materials to the specified floor. The above process has a short transit time and high efficiency, thereby reducing the production cost for the enterprise.
