Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a building operation lifting device. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings. After the building frame is completed, interior decoration and renovation are required. Using material lifting devices during the decoration and renovation process can effectively save labor costs and improve the speed of material handling.

[0003] Material lifting devices used in operation generally include a support base, a lifting drive mechanism, and a material lifting plate for placing decoration materials. The decoration materials to be used are placed on the lifting plate and lifted. In the actual lifting process, the lifting plate is prone to slight shaking during the ascent. The lifting drive mechanism is usually connected to the lifting plate with a rope. During the winding process, the entanglement point is fixed, which can easily cause the rope to accumulate, making it easy for the rope to get tangled when unwinding. Utility Model Content

[0004] The technical problem this invention aims to solve is that the lifting plate is prone to slight shaking during the upward movement of the lifting plate, and the fixed winding point during the winding process can easily cause the rope to pile up, making it easy for the rope to get tangled when unwinding.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a construction operation lifting device, comprising a base, columns, and a top plate. The columns are fixedly connected to the top of the base and are symmetrically distributed in pairs at the four corners of the base. The top plate is fixedly connected to the upper end of the columns. A slider is slidably mounted on the columns. A bearing box is fixedly connected between the opposite side walls of the slider. A side plate is fixedly connected to the bottom of the top plate. The side plates are L-shaped and symmetrically distributed from left to right.

[0006] The lifting assembly, located below the top plate and on one side of the side plate, is used for the stable lifting operation of the carrier box;

[0007] Anti-stacking components are located at the bottom of the top plate and above the side plates to standardize and improve the neatness of operations.

[0008] Furthermore, the lifting assembly includes a protrusion, a hook, a connecting rope, a guide wheel, a connecting frame, a stepper motor, and a winding wheel, wherein:

[0009] The protrusions are fixedly connected to the top of the carrier box and are symmetrically distributed. The protrusions are through-holes in the middle. The hooks are hung inside the protrusions. The guide wheels are rotatably connected to the top of the top plate. The connecting frame is mounted on the side of the side plate. The stepper motor is fixedly mounted on the connecting frame. One end of the take-up wheel is fixedly connected to the output end of the stepper motor. The other end of the take-up wheel is rotatably connected to the inner wall of the connecting frame. One end of the connecting rope is fixedly connected to the upper end of the hook. The other end of the connecting rope passes through the top plate, goes around the guide wheel, and is fixedly connected to the take-up wheel.

[0010] Furthermore, the anti-stacking assembly includes a vertical plate, a servo motor, a ball screw, and an adjusting block, wherein:

[0011] The upright plate is fixedly connected to the top of the side plate and is symmetrically distributed front and back. The servo motor is fixedly installed on the outer wall of the side plate. One end of the ball screw is fixedly connected to the output end of the servo motor, and the other end of the ball screw is rotatably connected to the upright plate. The adjusting block passes through the ball screw and is threadedly connected to it. The connecting bracket is fixedly connected to the top of the adjusting block. The side plate is provided with a limiting hole, and the bottom of the adjusting block passes through the limiting hole and slides inside it.

[0012] Furthermore, a side block is fixedly connected to the outer wall of the side plate, and the middle of the side block is through-shaped, with the connecting rope passing through the side block and sliding inside the side block.

[0013] Furthermore, the front side of the carrier box is open, the inner wall of the carrier box is provided with an inner plate, which is symmetrically distributed on the left and right, and a card plate is provided inside the carrier box, which is inserted between the inner plate and the inner wall of the carrier box.

[0014] Furthermore, the outer wall of the adjusting block is in contact with the inner wall of the limiting hole, the connecting frame is U-shaped, and the card plate is T-shaped.

[0015] The beneficial effects of this utility model after adopting the above structure are as follows:

[0016] (1) Pull out the card plate, load the material to be lifted into the carrier box, insert the card plate into the gap between the inner plate and the carrier box, and turn on the servo motors and stepper motors on both sides at the same time. The stepper motor drives the winding wheel to rotate and wind up the connecting rope. During the process, the guide wheel and side block guide the connecting rope to ensure the stability of the connecting rope.

[0017] (2) The operation of the servo motor causes the ball screw to rotate at a constant speed, which in turn causes the adjusting block to move back and forth under the action of the limit hole, causing the winding wheel to move back and forth, and the connecting rope to be evenly wound on the winding wheel, thus avoiding the problem of rope accumulation. During the lifting process, the carrier box slides on the column through each set of sliders, ensuring the stability during lifting or lowering and avoiding swaying. Attached Figure Description

A bearing box 5 is fixedly connected between the opposite side walls of the slider 4. A side plate 6 is fixedly connected to the bottom of the top plate 3. The side plate 6 is L-shaped and symmetrically distributed from left to right. The device also includes a lifting component and an anti-stacking component.

[0026] The lifting assembly is used for the stable lifting operation of the carrier box 5, and the anti-stacking assembly is used to ensure the neatness during the lifting operation.

[0027] like Figure 1-5As shown, to facilitate stable lifting of the carrier box 5, the lifting assembly includes a protrusion 7, a hook 8, a connecting rope 9, a guide wheel 10, a connecting frame 11, a stepper motor 12, and a take-up wheel 13. The protrusion 7 is fixedly connected to the top of the carrier box 5 and is symmetrically distributed. The center of the protrusion 7 is through-hole. The hook 8 is hung inside the protrusion 7. The guide wheel 10 is rotatably connected to the top of the top plate 3. The connecting frame 11 is located on the side of the side plate 6 and is U-shaped. The stepper motor 12 is fixedly mounted on the connecting frame 11. One end of the take-up wheel 13 is fixedly connected to the output end of the stepper motor 12, and the other end of the take-up wheel 13 is rotatably connected to the inner wall of the connecting frame 11. One end of the connecting rope 9 is fixedly connected to the upper end of the hook 8, and the other end of the connecting rope 9 passes through the top plate 3 and around the guide wheel 10 and is fixedly connected to the take-up wheel 13.

[0028] like Figure 1-3 As shown, in order to solve the problem of rope tangling during unloading caused by rope accumulation, the anti-accumulation component includes a vertical plate 14, a servo motor 15, a ball screw 16, and an adjusting block 17. The vertical plate 14 is fixedly connected to the top of the side plate 6 and is symmetrically distributed front and back. The servo motor 15 is fixedly installed on the outer wall of the side plate 6. One end of the ball screw 16 is fixedly connected to the output end of the servo motor 15, and the other end of the ball screw 16 is rotatably connected to the vertical plate 14. The adjusting block 17 passes through the ball screw 16 and is threadedly connected to it. The connecting bracket 11 is fixedly connected to the top of the adjusting block 17. The side plate 6 is provided with a limiting hole 18. The bottom of the adjusting block 17 passes through the limiting hole 18 and slides inside it. The outer wall of the adjusting block 17 is in contact with the inner wall of the limiting hole 18.

[0029] To enhance the limiting effect on the winding point of the connecting rope 9, a side block 19 is fixedly connected to the outer wall of the side plate 6. The middle of the side block 19 is through-shaped, and the connecting rope 9 passes through the side block 19 and slides inside the side block 19.

[0030] To facilitate the placement and removal of materials, the front of the carrier box 5 is open.

At the same time, the servo motors 15 and stepper motors 12 on both sides are turned on. The stepper motor 12 drives the winding wheel 13 to rotate and wind up the connecting rope 9. During the process, the guide wheel 10 and the side block 19 guide the connecting rope 9 to ensure the stability of the connecting rope 9. The operation of the servo motor 15 causes the ball screw 16 to rotate at a constant speed, which in turn causes the adjusting block 17 to move back and forth under the action of the limiting hole 18, so that the winding wheel 13 moves back and forth and winds the connecting rope 9 evenly on the winding wheel 13, thereby avoiding the problem of rope accumulation. During the lifting process, the carrier box 5 slides on the column 2 through each set of sliders 4 to ensure the stability during lifting or lowering and avoid swaying.
