Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a lifting mechanism applicable to a double-speed chain line body as Figures 1-4 shown, which includes a building body 101 and a lifting assembly. A plurality of floor surfaces 102 are arranged at intervals on the front surface of the building body 101. In the figure, the floor surfaces 102 are set to three, that is, three floors.

[0024] In a preferred embodiment, the lifting mechanism is arranged inside the building body 101. The lifting mechanism includes a lift shaft 201 opened inside the building body 101. A lift frame 202 is movably arranged inside the lift shaft 201. The bottom end of the inner wall of the lift frame 202 is fixedly connected with a first double-speed chain conveyor rack 203. A conveying mechanism is arranged at the top end of the floor surface 102. Through the cooperation of the conveying mechanism, materials are conveyed onto the first double-speed chain conveyor rack 203 inside the lift frame 202, and then the lift frame 202 is lifted in the lift shaft 201 to the corresponding floor. Then, through the operation of the first double-speed chain conveyor rack 203 and the cooperation with the conveying mechanism on the corresponding floor, the materials on the first double-speed chain conveyor rack 203 can be moved out, thereby completing the rapid conveying of materials between different floors and improving the conveying efficiency of the materials.

[0025] The conveying mechanism includes a connecting door 301 opened on the front of the building 101, and a second speed chain conveyor frame 302 is arranged on the top of the floor 102. The second speed chain conveyor frame 302 is opposite to the connecting door 301. When the lifting frame 202 is lifted and lowered in the lifting shaft 201 so that the first speed chain conveyor frame 203 therein is aligned with a second speed chain conveyor frame 302, the second speed chain conveyor frame 203 can be moved by the aligned second speed chain conveyor frame 302 and the first speed chain conveyor frame 203. The material on 302 is moved to the first speed chain conveyor frame 203, or the material on the first speed chain conveyor frame 203 is moved to the second speed chain conveyor frame 302, wherein a rolling door can be installed in 391. Only when the first speed chain conveyor frame 203 moves to the position of a connecting door 301, the rolling door in the connecting door 301 can be opened to transport the material, thereby avoiding the danger caused by the connecting door 301 being in the open state all the time, thereby improving the safety of work.

[0026] The inner wall of the lifting shaft 201 is fixedly connected with a fixing plate 401, and a first rotating rod 402 is rotatably connected between the fixing plate 401 and the inner wall of the lifting shaft 201. A first sprocket 403 is fixedly sleeved on the outer wall of the first rotating rod 402, and a first chain 404 is meshedly arranged on the outer wall of the first sprocket 403. One end of the first chain 404 is fixedly connected to the top of the lifting frame 202. A servo motor 601 is installed on one side of the fixing plate 401, and one end of the servo motor 601 is drivingly connected to one end of the first rotating rod 402. The first chain 404 is arranged in a straight chain type, and a counterweight mechanism is arranged at the other end of the first chain 404. The servo motor 601 can drive the first rotating rod 402 to rotate, and the rotation of the first rotating rod 402 drives the first sprocket 403 to rotate. The rotation of the first sprocket 403 can drive the meshing first chain 404 to move, thereby driving the lifting frame 202 to lift in the lifting shaft 201, and a limit position is set between the lifting frame 202 and the lifting shaft 201, so that the lifting frame 202 can stably perform lifting work.

[0027] Among them, the counterweight mechanism includes a counterweight block 503 movably arranged on the inner wall of the lifting shaft 201, the other end of the first chain 404 is fixedly connected to the top of the counterweight block 503, a second rotating rod 501 is rotatably connected between the fixed plate 401 and the inner wall of the lifting shaft 201, a second sprocket 502 is fixedly sleeved on the outer wall of the second rotating rod 501, the first chain 404 is meshedly arranged on the outer wall of the second sprocket 502, and a synchronization mechanism is arranged between the second rotating rod 501 and the first rotating rod 402. Through the cooperation of the counterweight block 503, the rotation of the first sprocket 403 can stably drive the first chain 404 to move, thereby improving the stability of the lifting and lowering of the lifting frame 202.

[0028] Among them, the synchronization mechanism includes third sprockets 602 respectively and fixedly sleeved on the outer walls of the second rotating rod 501 and the first rotating rod 402. A second chain 603 is meshed between the two third sprockets 602. The second chain 603 is arranged in a loop chain form. Through the cooperation of the second chain 603 and the two third sprockets 602, the two first rotating rods 402 can rotate synchronously and stably. Thus, when the servo motor 601 works to drive the first rotating rod 402 to rotate, it can stably ensure that the first sprocket 403 and the second sprocket 502 rotate simultaneously, thereby ensuring that the first chain 404 can move stably along with the rotation of the first sprocket 403 and the second sprocket 502.

[0029] Among them, a partition plate 801 is fixedly connected to the inner wall of the lift shaft 201. A communication hole 802 is opened at the top of the partition plate 801. Both ends of the first chain 404 respectively penetrate through the interiors of the two communication holes 802. The lift frame 202 is separated from the transmission part by the partition plate 801, thereby ensuring the stability of the lifting operation of the lift frame 202.

[0030] Among them, limiting blocks 702 are fixedly connected to both sides of the counterweight 503. Limiting grooves 701 are symmetrically opened on the inner wall of the lift shaft 201. The outer walls of the two limiting blocks 702 are respectively slidably connected to the inner walls of the two limiting grooves 701. A plurality of notches 703 are opened on the outer wall of the limiting block 702. A plurality of rollers 704 are rotatably arranged at intervals on the inner wall of the notch 703. The outer walls of the plurality of rollers 704 are all attached to the inner wall of the limiting groove 701. Through the mutual limitation of the limiting block 702 and the limiting groove 701, the counterweight 503 can be lifted and lowered stably. At the same time, through the arrangement of the rollers 704, the counterweight 503 can move more smoothly, so that the first chain 404 can stably drive the counterweight 503 to move, thereby ensuring the stability of the lifting of the lift frame 202.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
