Description

Technical Field

[0001] This utility model relates to the field of material lifting devices for construction, and in particular to a material lifting device for construction. Background Technology

[0002] Material hoisting devices are important equipment in construction engineering, which can conveniently lift the required materials from low to high places, thereby providing various materials needed during the construction of high-rise buildings. Existing material hoisting devices mostly use trolleys for storage and then lift and transport powdery and granular materials such as sand. This method limits the amount of material that can be transported at one time, and requires more lifts when lifting larger amounts of material, so efficiency needs to be improved.

[0003] However, existing technologies cannot reduce the lateral swaying that occurs when lifting materials. This swaying can cause the material hoist's frame structure to be subjected to additional lateral forces, increasing the risk of structural instability and potentially leading to frame collapse and serious safety accidents. The swaying during lifting can also cause material spillage and loss, as well as pollution at the construction site. Furthermore, the inability to quickly install guardrails on the holding racks can delay the overall installation progress, affecting construction schedule and efficiency. The absence or slow installation of guardrails can also cause inconvenience to construction workers when loading and unloading materials, impacting work efficiency.

[0004] In response to this technical problem, this application proposes a material lifting device for construction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material lifting device for construction.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a material lifting device for construction, comprising a base plate 1, with support plates 1 and 2 fixedly connected to the top left and right ends of the base plate 1, support plates 2 and 6 fixedly connected to the top ends of the two support plates 1 and 2, and a connecting column 5 rotatably connected to the top ends of the two support plates 1 and 2. Wheels 4 are fixedly connected to the left and right ends of the connecting column 5, and a bevel gear 18 is fixedly connected to the right end of the connecting column 5. A bevel gear 29 is meshed with the bottom side of the bevel gear 18, and a bevel gear 4 22 is provided on the bottom side of the bevel gear 29 through a connecting pipe. A bevel gear 3 20 is meshed with the bottom side of the bevel gear 4 22. The protective plates 2 and 21 are fixed by ropes 7 through traction handles 8 on opposite sides of the two protective plates 2 and 21. The bevel gear 3 20 is rotated by a motor 9, and the rotation of the bevel gear 3 20 drives the bevel gear 4 22 meshing with it to rotate. The rotation of the bevel gear 4 22 then drives the bevel gear 2 19 fixed through the connecting pipe to rotate. The rotation of bevel gear 19 drives bevel gear 18, which meshes with bevel gear 19, to rotate together. The rotation of bevel gear 18 then drives the connecting column 5, which is fixed to bevel gear 18, to rotate together. The connecting column 5 then drives the rotating wheels 4, fixed at both ends of the connecting column 5, to rotate together. Because the fixing block 3 is fixed at both ends of the support plate 2, and the bottom side of the rotating wheel 4 is fitted with the outer wall of the connecting column 5, the fixing block 3 ensures that the rotating wheel 4 will not move left or right during rotation. At the same time, the support plate 2, 6 and the fixing block 3 ensure that the rotating wheel 4 reduces vibration and potential detachment during rotation. Ultimately, this allows the rack to move smoothly and rise more stably, reducing the risk of materials falling during lifting and thus reducing potential threats to personnel and objects on the ground. Stable operation reduces additional wear on equipment components caused by shaking, extending the equipment's service life. Protective plate 2 11 and protective plate 10 are respectively installed at the top center of the base plate 1.Limiting grooves 21 are provided on the front and rear sides of the second protective plate 11, and limiting blocks 17 are provided on the adjacent side of the first protective plate 10. Fixing grooves 2 15 are respectively provided on the inner walls of the second protective plate 11 and the first protective plate 10. Connecting blocks 13 are provided on the top and bottom sides of the second protective plate 11 and the first protective plate 10. Fixing grooves 1 14 are provided on the inner walls of the connecting blocks 13. Bolts 16 are provided on the inner walls of fixing grooves 1 14 and 2 15, and nuts 12 are threaded onto the top of the bolts 16. The limiting blocks 17 on the adjacent side of the two first protective plates 10 are inserted into the inner walls of the limiting grooves 21 on the left and right sides of the second protective plate 11. Because the limiting blocks 17 and the limiting grooves 21 are riveted, initial fixing can be achieved by inserting the limiting blocks 17 into the inner walls of the limiting grooves 21. Then, the connecting blocks 13 are placed at the corner formed after the first protective plate 10 and the second protective plate 11 are riveted together. On both the top and bottom sides, there are two fixing grooves 14 formed on the inner wall of the connecting block 13. One fixing groove 14 aligns with the fixing groove 15 formed on the inner wall of the protective plate 11, and the other fixing groove 14 aligns with the fixing groove 15 formed on the inner wall of the protective plate 10. After aligning the fixing grooves 14 and 15, bolts 16 are inserted into the inner walls of the fixing grooves 14 and 15, and then fixed with nuts 12. This quick-installation guardrail shortens construction preparation time, allowing the material lifting device to be put into use more quickly, thereby improving construction efficiency. It also reduces the occurrence of accidents, avoiding property damage and additional maintenance costs caused by accidents. The quick-installation guardrail facilitates daily inspection and maintenance, ensuring that the guardrail is always in good working condition.

[0025] Reference Figure 2 and Figure 3 A motor 9 is mounted on the bottom of the right support plate 12 via a support frame. The drive end of the motor 9 is fixedly connected to the right side of the bevel gear 3 20. The fixing slot 14 and fixing slot 2 15 are symmetrical. Fixing blocks 3 are fixedly connected to both ends of the support plate 2 6. The bottom sides of the two fixing blocks 3 are sleeved on the left and right ends of the connecting column 5. The outer walls of the two rotating wheels 4 are set on the inner walls of the bottom sides of the two fixing blocks 3. Ropes 7 are set on the inner walls of the two rotating wheels 4. At the same time, the support plate 2 6 and the fixing blocks 3 can ensure that the rotating wheels 4 are less likely to fall off due to vibration when rotating. A traction handle 8 is set at one of the opposite ends of the protective plate 2 11. The nut 12 is located on the top side of the connecting block 13. The outer walls of the bevel gear 2 19 and the bevel gear 18 are rotatably connected to the inner wall of the right support plate 12.

[0026] Working principle: First, insert the limiting blocks 17 on the adjacent side of the two protective plates 10 into the inner walls of the limiting grooves 21 on both sides of the protective plate 11. Since the limiting blocks 17 and the limiting grooves 21 are riveted, the initial fixation can be achieved by inserting the limiting blocks 17 into the inner walls of the limiting grooves 21. Then, place the connecting block 13 on the upper and lower sides of the corner formed after the protective plates 10 and 11 are riveted together. Then, through the fixing grooves 14 opened in the inner wall of the connecting block 13, there are two fixing grooves 11. 4. Therefore, one fixing groove 14 is aligned with the fixing groove 15 on the inner wall of the second protective plate 11, and the other fixing groove 14 is aligned with the fixing groove 15 on the inner wall of the first protective plate 10. After aligning the fixing grooves 14 and 15, the bolts 16 are inserted into the inner walls of the fixing grooves 14 and 15, and then fixed with nuts 12. Finally, the protective railing of the shelf is installed. Then, the rope 7 is used to pull the handles on the opposite side of the two protective plates 11. 8. The protective plate 21 is fixed, and the motor 9 controls the rotation of the bevel gear 3 20. The rotation of the bevel gear 3 20 drives the bevel gear 4 22, which meshes with the bevel gear 3 20, to rotate together. The rotation of the bevel gear 4 22 drives the bevel gear 2 19, which is fixed through the connecting pipe, to rotate together. The rotation of the bevel gear 2 19 drives the bevel gear 1 18, which meshes with the bevel gear 2 19, to rotate together. The rotation of the bevel gear 1 18 drives the connecting column 5, which is fixed to the bevel gear 1 18, to rotate together. The connecting column 5 drives the rotating wheels 4, which are fixed at both ends of the connecting column 5, to rotate together. Because the fixing block 3 is fixed at both ends of the support plate 2 6, and the bottom side of the rotating wheel 4 is fitted with the outer wall of the connecting column 5, the fixing block 3 can ensure that the rotating wheel 4 will not move left or right when rotating. At the same time, the support plate 2 6 and the fixing block 3 can ensure that the rotating wheel 4 will reduce vibration and fall off when rotating. Finally, the shelf can move smoothly when it rises.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
