Description

Technical Field

[0001] This utility model relates to the field of building construction lifting equipment technology, specifically to a lifting device for anti-slip materials used in building construction. Background Technology

[0002] During construction, lifting equipment is often used to lift cylindrical or long pole-shaped building materials such as steel pipes, wooden poles, and PVC pipes. In existing technologies, lifting devices are typically used in conjunction with clamping components for fixation. For example, patent document CN202222454774.4 discloses a material stabilizing and lifting device for construction, which uses rubber blocks and clamping screws for clamping, thereby increasing friction to a certain extent.

[0003] However, the aforementioned structure primarily relies on rubber friction for slip resistance. When the surface of the building materials is covered with dust, water stains, or oil, the friction decreases significantly, making it easy for the materials to slip or even detach during lifting, posing a safety hazard. Furthermore, the rubber blocks are fixed structures, making them inconvenient to replace for different building materials, resulting in insufficient adaptability.

[0004] Therefore, there is an urgent need for an improved lifting device that can form a reliable mechanical fit during clamping, and has modular anti-slip pads and a multi-point clamping structure, thereby further improving anti-slip performance and construction adaptability. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting device for anti-slip materials used in building construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting device for anti-slip materials used in construction includes a first support member, a second support member, and a hoisting assembly. The second support member is slidably connected to both ends of the first support member. Both the first and second support members are equipped with clamping components. Each clamping component includes a base frame, a support frame, and a clamping screw. The support frame is fixed to the base frame and is used to support cylindrical or long rod-shaped building materials. The lower end of the clamping screw is equipped with a pressure ring.

[0008] The inner wall of the support frame and the inner arc surface of the pressure ring are provided with detachable anti-slip pads. The anti-slip pads have a wedge-shaped tooth block structure, which can fit into the outer wall of the building material when clamped to prevent the building material from slipping during the lifting process.

[0009] Preferably, the anti-slip pad is provided with a plurality of wedge teeth evenly distributed along the circumferential direction, and a gap groove is formed between adjacent wedge teeth to enhance the fitting effect.

[0010] Preferably, the anti-slip pad is composed of a metal toothed surface layer and an elastic buffer layer. The metal toothed surface layer engages with the outer wall of the building material, and the elastic buffer layer is used to absorb the clamping impact force.

[0011] Preferably, the anti-slip pad is installed in a limiting groove provided on the support frame or pressure ring, and can be quickly installed and removed through a buckle or pin structure.

[0012] Preferably, both sides of the support frame are provided with lateral pressing components. The lateral pressing components include adjusting screws and toothed pads. The toothed pads can form a clamping fit with the side wall of the building material, thereby forming a three-point clamping structure together with the top pressure ring.

[0013] Preferably, a V-shaped limiting groove is provided in the middle of the bottom frame, and the V-shaped limiting groove fits into the outer arc surface of the building material to prevent the building material from rolling during the support process.

[0014] Preferably, the hoisting assembly includes a hoisting frame, a hoisting ring, and several hoisting cables. The lower ends of the hoisting cables are respectively fixed to the bottom frames of the first support and the second support to achieve uniform lifting under force.

[0015] Preferably, the first support member is provided with a frame strip, and the second support member is provided with an insert strip at one end. The insert strip is engaged with the positioning hole on the frame strip by a positioning bolt to adjust the clamping range.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This novel anti-slip material lifting device for building construction features detachable wedge-tooth anti-slip pads on the inner walls of both the support frame and the pressure ring. Combined with a composite design of metal tooth surfaces and an elastic buffer layer, it not only forms a mechanical fit with the outer wall of the building material when clamped, significantly enhancing the anti-slip gripping force, but also allows the elastic buffer layer to absorb local impacts, preventing damage to the surface of the building material. Thus, it balances strong fixation with safety protection.

[0018] 2. This construction anti-slip material lifting device employs a combination of a top pressure ring, side pressure components, and a bottom V-shaped limiting groove to form a three-dimensional force-bearing closed-loop structure with the combined action of top pressure, side pressure, and bottom limiting. This mechanical closed loop effectively suppresses slippage, rolling, and swaying of building materials during hoisting, ensuring the overall stability and balance of the clamping, and significantly improving the safety of the construction process.

[0019] 3. This construction anti-slip material lifting device features a detachable modular anti-slip pad, allowing for quick replacement of pads with different tooth profiles based on the material and surface characteristics of the building material, thus improving the device's adaptability and service life. Simultaneously, the lifting assembly, with its evenly distributed connection between the lifting frame and multiple lifting cables, ensures more uniform force distribution during lifting, further reducing the risk of eccentric loading and enhancing overall reliability, thereby guaranteeing the safety and adaptability of the construction process.

[0026] 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.

[0027] Please see Figures 1-5 As shown in the accompanying drawings, the specific embodiments of this utility model will be further described below. It should be understood that the following embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection:

[0028] like Figure 1As shown, this embodiment provides a lifting device for anti-slip materials used in building construction, including a first support member 1, a second support member 2, and a hoisting assembly 3. Both ends of the first support member 1 are slidably connected to the second support member 2, allowing for telescopic adjustment according to the length of the clamped building material. The hoisting assembly 3 is arranged directly above the first support member 1 and is used to connect with lifting equipment to achieve overall hoisting.

[0029] like Figure 2 As shown, the first support member 1 has clamping strips 11 on both sides, and the second support member 2 has an insert 21 at one end near the first support member 1. The insert 21 is connected to the positioning hole 12 on the clamping strip 11 by a positioning bolt 22. By adjusting the position of the insert 21 and the positioning hole 12, the clamping range can be flexibly changed to accommodate building materials of different diameters and lengths.

[0030] like Figure 3 As shown, both the first support member 1 and the second support member 2 are equipped with clamping members 4. The clamping member 4 includes a base frame 41, a support frame 42, and a clamping screw 46 that cooperates with the rotating base 43. The support frame 42 is vertically fixed to the base frame 41 and is used to support the cylindrical or long rod-shaped building material being lifted. The lower end of the clamping screw 46 is equipped with an arc-shaped pressure ring 47, which can move vertically downward when the screw is rotated to apply a clamping force to the building material.

[0031] Optionally, the clamping member (4) may be provided with a screw hole plate (44) for guiding and limiting, the pressing screw (46) passes through the screw hole plate (44) and cooperates with the rotating seat (43); the rotating rod (45) is connected to the pressing screw (46) to facilitate manual rotation for applying pressure.

[0032] like Figure 4 As shown, anti-slip pads 48 are provided on the inner wall of the support frame 42 and the inner arc surface of the pressure ring 47. The anti-slip pads 48 are detachable modules, installed in the limiting groove, and fixed by snap-fit ​​or pins. The surface of the anti-slip pads 48 has several wedge-shaped teeth 482 distributed circumferentially, forming gaps between adjacent wedge-shaped teeth, allowing them to partially embed into the outer wall of the building material during clamping, thus significantly enhancing anti-slip capability. To improve service life, the anti-slip pads 48 adopt a composite design of a metal toothed surface and an elastic buffer layer 481. The metal toothed surface is responsible for engaging with the building material, while the elastic layer 481 absorbs the impact force during clamping.

[0033] In a further design, lateral pressing components are also provided on both sides of the support frame 42, such as... Figure 5 As shown. The component includes an adjusting screw and a toothed pad at its end, which can apply clamping force from both sides of the building material, forming a three-point clamping structure with the top pressure ring 47. This three-point force distribution effectively prevents the building material from deflecting or loosening when the force is uneven, thereby improving the overall stability.

[0034] To further prevent building materials from rolling during lifting, this embodiment features a V-shaped limiting groove 411 in the middle of the base frame 41. This limiting groove 411 fits snugly against the outer arc surface of the building material, allowing the material to be stably positioned on the base frame 41. Even if disturbed by external forces during hoisting, it is not prone to lateral rolling.

[0035] The hoisting assembly 3 includes a hoisting frame 31, a hoisting ring 32, and several hoisting cables 33, such as Figure 1 As shown. The lifting frame 31 is horizontally arranged above the first support member 1, and a lifting ring 32 is fixed on its top for engagement with the hook of the lifting equipment. Multiple lifting cables 33 are evenly distributed and fixed on the bottom surface of the lifting frame 31. The lower ends of the lifting cables 33 are connected to the bottom frames 41 of the first support member 1 and the second support member 2, respectively, so as to maintain the uniform force on the entire device during the lifting process and avoid uneven loading.

[0036] The working process of this utility model is as follows: In use, firstly, adjust the relative distance between the first support member 1 and the second support member 2 according to the length of the building material to be lifted, and fix them by the positioning cooperation of the insert strip 21 and the frame strip 11. Then, rotate the holding screw 46 so that the pressure ring 47 is positioned above the building material; simultaneously, adjust the screw of the lateral holding assembly as needed to gradually bring the toothed pads closer to both sides of the building material. When the pressure ring 47 and the pads on both sides are pressed against the outer wall of the building material, the anti-slip pad 48 at the bottom of the support frame 42 and the limiting groove 411 together limit and prevent slippage of the building material. Finally, connect the hoisting assembly 3 to the lifting equipment to complete the vertical lifting and transportation of the building material.

[0037] Therefore, this embodiment, by setting wedge-shaped toothed anti-slip pads, replaceable modular structures, and a three-point clamping method, can effectively improve clamping stability and anti-slip performance, overcome the shortcomings of existing technologies that rely on rubber friction, and has higher safety and adaptability.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
