[0025] Specifically, first, the goods are placed above the bearing plate 3, and the goods are tightly attached to the backboard 2, then, the electric push rod 4 is started to pull the connecting plate 5 to move, in turn, drive the rack plate 6 to move, the movement of the rack plate 6 will promote the connecting block 7 to move synchronously, in turn, drive the clamping plate 8 to move, in the process of moving the rack plate 6, because the rack plate 6 and the gear 9 are meshed with each other, so the gear 9 will be rotated, in turn, drive the rack plate 6 on the other side to move synchronously, so that the clamping plate 8 on both sides of the bearing plate 3 moves towards the center, clamps and fixes the goods, ensures that the goods can always maintain a stable posture in the whole process of lifting and lowering, and will not appear inclination, overturning and other conditions.
[0026] After the goods are fixed, the servo motor of the elevator body 1 starts to work, drives the transmission mechanism to operate, and the transmission mechanism further drives the back plate 2 to move, and finally the goods are sent to the appropriate height.
[0027] With reference to Figure 1 and Figure 2 , the support assembly comprises a support rod 11, and the outer wall of the support rod 11 is fixedly connected to the outer wall of the elevator body 1, and the elevator body 1 is rectangular.
[0028] Specifically, the support rod 11 supports the elevator body 1 and is connected to the sliding plate 12.
[0029] With reference to Figure 1 , Figure 2 and Figure 4 , the lower surface of the support rod 11 is fixedly connected with the sliding plate 12, and the inner walls of the sliding plate 12 are slidably connected with the limiting rods 13. The lower surface of the limiting rod 13 is fixedly connected with the bottom plate 14, and the outer wall of the sliding plate 12 is slidably connected to the upper surface of the bottom plate 14. The outer wall of the bottom plate 14 is provided with a driving motor 15, and the output end of the driving motor 15 is provided with a threaded column 16, and the outer wall of the threaded column 16 is rotatably connected to the inner wall of the bottom plate 14. The outer wall of the threaded column 16 is threadedly connected with a threaded block 17, and the outer wall of the threaded block 17 is slidably connected to the inner wall of the bottom plate 14. The outer wall of the threaded block 17 is fixedly connected with a connecting rod 18, and the outer wall of the connecting rod 18 is slidably connected to the inner wall of the bottom plate 14. The outer wall of the connecting rod 18 is fixedly connected with an L-shaped plate 19, the outer wall of the L-shaped plate 19 is fixedly connected to the outer wall of the sliding plate 12, and the outer wall of the L-shaped plate 19 is slidably connected to the outer wall of the bottom plate 14.
[0030] Specifically, when the place where the elevator is used has obstacles, first place the bottom plate 14 in a place without obstacles and can be placed stably, and then start the driving motor 15 to drive the threaded column 16 to rotate inside the bottom plate 14. Because the threaded block 17 is threadedly connected with the threaded column 16, and the upper and lower surfaces of the threaded block 17 are in contact with the inner wall of the bottom plate 14, the threaded column 16 can only drive the threaded block 17 to translate when rotating, and the threaded block 17 itself cannot rotate. While the threaded block 17 moves, it drives the connecting rod 18 and the L-shaped plate 19 to move together, and the movement of the L-shaped plate 19 drives the sliding plate 12 to move along the outer wall of the limiting rod 13, and the movement of the sliding plate 12 drives the support rod 11 and the elevator body 1 to move together. In this way, the elevator can flexibly avoid obstacles, and can also adjust the position according to the construction progress and the actual situation on site, so as to better adapt to the complex construction environment.
[0031] Working principle: when the elevator is needed, first place the goods above the bearing plate 3, and make the goods close to the back plate 2, then start the electric push rod 4, the electric push rod 4 pulls the connecting plate 5 to move, and then drives the rack plate 6 connected with the connecting plate 5 to move, the rack plate 6 moves to drive the connecting block 7 to move, thereby driving the clamping plate 8 to move together, when the rack plate 6 moves, since the rack plate 6 is engaged with the gear 9, the gear 9 rotates, the gear 9 rotates to drive the rotating column 10 to rotate, the rotating column 10 ensures that the gear 9 will not fall off, the rotation of the gear 9 drives the rack plate 6 on the other side to move synchronously, thereby making the clamping plates 8 on both sides of the bearing plate 3 move towards the center, clamping and fixing the goods, ensuring that the goods always maintain a stable posture during lifting and lowering, and tilting, overturning and other situations will not occur, after the goods are fixed, the servo motor of the elevator body 1 drives the transmission mechanism to operate, thereby driving the back plate 2 to move, and the goods are sent to the appropriate height, when there are obstacles where the elevator is needed, place the bottom plate 14 in a place without obstacles and can be placed stably, start the driving motor 15, the driving motor 15 drives the threaded column 16 to rotate inside the bottom plate 14, since the threaded block 17 is screwed with the threaded column 16, and the upper and lower surfaces of the threaded block 17 are fitted with the inner wall of the bottom plate 14, the threaded column 16 can only drive the threaded block 17 to translate and cannot rotate, while the threaded block 17 moves, it also drives the connecting rod 18 and the L-shaped plate 19 to move, the L-shaped plate 19 moves to drive the sliding plate 12 to move on the outer wall of the limiting rod 13, the limiting rod 13 ensures that the direction of the displacement of the sliding plate 12 is the direction of movement, preventing the sliding plate 12 from tilting when moving, thereby driving the supporting rod 11 and the elevator body 1 to move, so that the elevator can flexibly avoid obstacles, or adjust the position according to the construction progress and the site situation, better adapt to the complex and changeable construction environment, that is, the elevator not only ensures that the goods always maintain a stable posture during lifting and lowering, and tilting, overturning and other situations will not occur, but also can flexibly avoid obstacles, or adjust the position according to the construction progress and the site situation, better adapt to the complex and changeable construction environment.
