Description

Technical Field

[0001] The present invention relates to the technical field of elevator devices, and particularly relates to an elevator automatic driving mechanism. Background Art

[0002] In some large-scale farms with several layers of breeding houses, such as livestock farms like pig farms, cattle farms, and sheep farms, in order to facilitate the transfer of livestock, special elevators for transporting livestock are generally provided. For example, when separating livestock cubs or transporting livestock out of the pen, the livestock on the upper floors of the breeding house can be quickly driven to the lower floors or even directly into the livestock transport vehicle through the elevator. However, the existing special elevators for livestock do not have a dedicated automatic driving mechanism, making it difficult for breeders to drive the livestock out of the elevator. If the livestock are driven out violently, they may panic and cannot find the elevator exit, thus crashing around in the narrow space of the elevator, which can easily lead to safety accidents and the elevator cannot have a long service life. Therefore, it is necessary to set up an automatic driving mechanism in this special elevator for transporting livestock to quickly and safely drive the livestock out of the elevator and reduce potential safety hazards.

DETAILED DESCRIPTION

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, an elevator automatic driving mechanism, the driving mechanism body includes a car rear wall 1, a bottom plate 2, a front plate 3, a scissors structure and a driving device, and the scissors structure is movably connected between the car rear wall 1 and the front plate 3 above the bottom plate 2. The scissors-type structure includes a plurality of connecting arms and a plurality of transfer support shafts which are movably connected in a scissors-type shape. A longitudinally arranged fixed guide groove 4 is provided on the upper part of the rear wall 2 of the car, a fixed support shaft 5 is provided on the lower part of the rear wall 1 of the car, and two connecting arms located on one side of the rear wall 1 of the car are respectively movably connected to the fixed guide groove 4 and the fixed support shaft 5. A front plate guide groove 6 corresponding to the position of the fixed guide groove 4 is provided on the upper part of the front plate 3. The front plate guide groove 6 is also longitudinally arranged on the upper part of the front plate 3 so that it is completely symmetrical with the fixed guide groove 4. A front plate support shaft 7 corresponding to the position of the fixed support shaft 5 is provided on the lower part of the front plate 3. The two connecting arms located on one side of the front plate 3 are respectively movably connected to the front plate guide groove 6 and the front plate support shaft 7. The driving device is arranged below the bottom plate 2, and the driving device is connected to the fixed support shaft 5 through a rocker rod 8 which passes through the bottom plate 2, so that the scissors-type structure can be retracted or pushed out by the driving device to complete the function of driving pigs.

[0018] Furthermore, the connecting arms in this embodiment include an active arm 9, an outer rear connecting arm 10, an inner middle connecting arm 11, an outer middle connecting arm 12, an inner front connecting arm 13 and an outer front connecting arm 14 that are movably connected together, a total of 6 connecting arms. Of course, the number of connecting arms can also be designed according to the actual size of the car, and the number should be an even number, so that the connecting arms can be combined in pairs to form a scissor-like shape, such as 8 or 10. The lower end of the active arm 9 is movably connected to the fixed support shaft 5, the upper end of the outer rear connecting arm 10 is movably connected to the fixed guide groove 4 through the rear guide member 15, the lower end of the inner middle connecting arm 11 is movably connected to the lower end of the outer rear connecting arm 10 through the transfer support shaft 16, the upper end of the outer middle connecting arm 12 is movably connected to the upper end of the active arm 9 through the transfer support shaft 16, the lower end of the inner front connecting arm 13 is movably connected to the lower end of the outer middle connecting arm 12 through the transfer support shaft 16, and the upper end of the inner front connecting arm 13 is movably connected to the lower end of the outer middle connecting arm 12 through the transfer support shaft 16. It is movably connected in the front plate guide groove 6, the upper end of the outer front connecting arm 14 is movably connected to the upper end of the inner middle connecting arm 11 through the adapter support shaft 16, the lower end of the outer front connecting arm 14 is movably connected to the front plate support shaft 7, the middle of the active arm 9 and the middle of the outer rear connecting arm 10, the middle of the outer middle connecting arm 12 and the middle of the inner middle connecting arm 11, the middle of the outer front connecting arm 14 and the middle of the inner front connecting arm 13 are rotatably connected together through the adapter support shaft 16 respectively. The above connection method enables all connecting arms to form the overall shape of a scissors-fork structure.

[0019] Specifically, when the scissor structure is folded, all the connecting arms are moved toward the rear wall 1 of the car. As the scissor structure is gradually folded, the upper end of the active arm 9 gradually moves toward the rear wall 1 of the car. At the same time, the middle of the active arm 9 drives the lower end of the outer rear connecting arm 10 to move toward the rear wall 1 of the car through the transfer support shaft 16. Driven by the active arm 9, the upper end of the outer rear connecting arm 10 gradually slides to the upper end of the fixed guide groove 4 through the rear guide member 15, so that the outer rear connecting arm 10 finally moves close to the rear wall 1 of the car, and the upper end of the active arm 9 and the lower end of the outer rear connecting arm 10 respectively drive the outer middle connecting arm 12 and the inner middle connecting arm 11 to move together around the transfer support shaft 16 in the middle through the transfer support shaft 16, so as to transmit the pulling force in turn. The thrust is then delivered to the outer front connecting arm 14 and the inner front connecting arm 13 connected to the front plate 3, wherein the upper end of the inner front connecting arm 13 slides to the upper end of the front plate guide groove 6 through the front guide member 17 when the inner front connecting arm 13 is completely close to each other; when the scissor-type structure is to be unfolded and pushed out, the fixed support shaft 5 is driven to rotate through the swing rod 8, forcing the upper end of the active arm 9 to move away from the rear wall of the car 1, and driving the outer rear connecting arm 10 to move downward along the fixed guide groove 4 through the rear guide member 15, thereby expanding the active arm 9 and the outer rear connecting arm 10 into a scissor-type shape with the transfer support shaft 16 as the fulcrum; as the swing rod 8 rotates, the thrust is sequentially transmitted to the outer front connecting arm 14 and the inner front connecting arm 13 connected to the front plate 3, thereby pushing out the front plate 3, and achieving the purpose of driving the livestock out of the elevator car.

[0020] Furthermore, the driving device is arranged below the bottom plate 2, and the driving device is connected to the fixed support shaft 5 through a swing rod 8. The driving device includes an oil cylinder 18, an oil pipe 19, and a pumping station 20. An oil cylinder support 21 and a pumping station support 22 are provided on the lower surface of the bottom plate 2. The oil cylinder support 21 is arranged close to one side of the car rear wall 1. The oil cylinder 18 is fixed below the bottom plate 2 through the oil cylinder support 21. The piston rod 23 of the oil cylinder 18 is located on one side of the car rear wall 1. A through hole is provided on the bottom plate 2 on one side of the car rear wall 1. The swing rod 8 is movably connected in the through hole. The upper end of the swing rod 8 passes through above the bottom plate 2 and is connected to the fixed support shaft 5. The lower end of the swing rod 8 passes through below the bottom plate 2 and is connected to the piston rod 23. The pumping station 20 is fixedly connected below the bottom plate 2 through the pumping station support 22. The oil cylinder 18 is connected to the pumping station 20 through the oil pipe 19. A closing switch 25 is provided below the bottom plate 2. The closing switch 25 is electrically connected to the oil cylinder 18 through a wire. In this way, the rotational torque is transmitted to the scissor structure through the swing rod 8 to control the scissor structure to close or unfold. When the piston rod 23 extends away from the oil cylinder 18, the scissor structure is in the extended (unfolded) state at this time; when the piston rod 23 contracts and approaches the oil cylinder 18, the scissor structure is in the closed state at this time.

[0021] Rollers 24 that abut against the bottom plate 2 are provided on the front and rear sides of the bottom of the front plate 3. The rollers 24 make the movement of the front plate 3 smoother, avoid jamming, and can also reduce the friction between the front plate 3 and the bottom plate 2, extending the service life of the car.

[0022] Finally, it should be noted that these embodiments are only used to illustrate the present invention and do not limit the scope of the present invention. In addition, for those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the embodiments here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
