Description

Technical Field

[0001] This utility model relates to the field of steel structure hoisting technology, specifically to an auxiliary device for steel structure hoisting. Background Technology

[0002] In the construction industry, steel structures have become one of the mainstream building forms due to their advantages such as high strength, good toughness, and convenient construction. Steel structure hoisting, as a crucial link in the construction process, directly affects the project's progress and quality in terms of efficiency and safety. Currently, the industry commonly uses steel cables or hoisting slings to bundle and lift steel materials, but this traditional method has revealed significant efficiency bottlenecks in practical applications.

[0003] From an operational perspective, steel cables or slings require a significant amount of time for tedious binding and securing before hoisting, especially when dealing with different types of steel such as I-beams and steel pipes, where the binding angle and force need to be repeatedly adjusted to ensure stability. After hoisting, the dismantling process is equally time-consuming and labor-intensive. According to statistics from the construction site, the binding and dismantling time for a single hoisting operation using traditional methods accounts for more than 40% of the entire hoisting process, severely restricting construction efficiency.

[0004] In large-scale construction scenarios, this efficiency deficiency is even more pronounced. For example, in the construction of high-rise steel structure buildings, dozens of steel hoisting operations need to be completed every day. The time cost accumulated by traditional methods can lead to a significant extension of the construction period. At the same time, frequent manual binding operations increase the labor intensity of construction workers, and long-term repetitive work can easily lead to fatigue problems, further affecting operational accuracy and safety.

[0005] Furthermore, traditional binding methods are highly dependent on the operator's experience. The binding force and node selection for different specifications of steel all require manual judgment. Novice operators find it difficult to quickly master the skills, which can easily lead to loose binding or over-binding. The former may cause the steel to slip, while the latter will accelerate the wear and tear of the lifting slings and increase equipment wear and tear costs.

[0006] In summary, existing steel structure hoisting methods have significant shortcomings in terms of ease of operation, efficiency improvement, and cost control. There is an urgent need for a highly automated and easy-to-operate auxiliary device to achieve rapid fixing and disassembly of steel during hoisting, thereby improving overall construction efficiency and reducing manual labor intensity and safety risks.

[0007] Therefore, an auxiliary device for steel structure hoisting is proposed. Summary of the Invention

[0008] The purpose of this utility model is to provide an auxiliary device for steel structure hoisting to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for hoisting steel structures, comprising a frame, with bidirectional screw rods symmetrically installed at both ends of the frame, two clamping plates installed on the bidirectional screw rods, and a steel section or steel pipe disposed between the two clamping plates;

[0010] Two first support plates are symmetrically installed in the middle of the frame. A threaded rod is threadedly connected to the first support plate, and a pressure plate is rotatably connected to the bottom end of the threaded rod.

[0011] Preferably, the pressure plate includes an arc-shaped plate; the middle of the upper surface of the arc-shaped plate is rotatably connected to the bottom end of the threaded rod, and straight plates are integrally formed on both sides of the arc-shaped plate, and multiple reinforcing ribs are installed between the upper surfaces of the straight plates and the arc-shaped plate.

[0012] Preferably, the clamping plate includes a vertical plate; the top of the vertical plate is connected to a bidirectional lead screw, the bottom of the vertical plate is fitted with a folding plate, and limit plates are symmetrically installed on both sides of the top of the vertical plate, the limit plates being slidably connected to the upper surface of the frame.

[0013] Preferably, a second support plate is installed on the upper surface of both ends of the frame, and the bidirectional lead screw is installed between the two second support plates.

[0014] Preferably, a drive motor or handle for driving a bidirectional lead screw is mounted on one of the second support plates.

[0015] Preferably, multiple hooks are symmetrically installed on the upper surface of the frame.

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

[0017] Improved fixing efficiency and stability: The bidirectional lead screw drives the clamping plate to move, enabling rapid clamping and positioning of structural steel or steel pipes. Combined with a threaded rod that presses down the pressure plate, this forms a three-dimensional fixing structure with the clamping plate side-clamping and the pressure plate pressing down. Compared to traditional steel cable binding, this design reduces fixing time by approximately 60%.

[0018] Enhanced applicability and flexibility: The pressure plate adopts a combination structure of curved plate and straight plate. The curved plate can be used for round cross-section steel materials such as steel pipes, while the straight plate is suitable for flat cross-section steel materials such as I-beams. With the design of folding plate and limiting plate, it can be compatible with steel structural components of various specifications. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an auxiliary device for steel structure hoisting, including a frame 1, with bidirectional screw rods 3 symmetrically installed at both ends of the frame 1, and two clamping plates 6 installed on the bidirectional screw rods 3. The two clamping plates 6 can move closer or further away as the bidirectional screw rods 3 rotate. A steel section or steel pipe is provided between the two clamping plates 6, and the two clamping plates 6 can clamp the steel section or steel pipe, thereby restricting its position.

[0027] Two first support plates 5 are symmetrically installed in the middle of the frame 1. A threaded rod 9 is threadedly connected to the first support plate 5. A motor or handle is installed at the top of the threaded rod 9. A pressure plate 7 is rotatably connected to the bottom of the threaded rod 9. The rotation of the threaded rod 9 can drive the pressure plate 7 to move up and down, thereby pressing and restricting the upper surface of the I-shaped steel or steel pipe.

[0028] like Figure 5 As shown: the pressure plate 7 includes an arc-shaped plate 71; the middle of the upper surface of the arc-shaped plate 71 is rotatably connected to the bottom end of the threaded rod 9, and straight plates 72 are integrally formed on both sides of the arc-shaped plate 71. Multiple reinforcing ribs 73 are installed between the straight plates 72 and the upper surface of the arc-shaped plate 71. With the above settings, the arc-shaped plate 71 can restrict the position of circular steel structures such as steel pipes when hoisting them. By rotating the threaded rod 9, the arc-shaped plate 71 can be moved downwards and then come into contact with the outer side of the steel structure. It can cooperate with the clamping plate 6 to restrict the position of the steel structure.

[0029] The two straight plates 72 can restrict the position of steel structures with flat surfaces, such as I-beams, when hoisting them. Rubber pads and other components that increase friction can also be installed on the lower surface of the pressure plate 7 to prevent slippage.

[0030] like Figure 4 As shown: the clamping plate 6 includes a vertical plate 61; the top of the vertical plate 61 is connected to the bidirectional lead rod 3, and a folding plate 62 is installed at the bottom of the vertical plate 61. Limiting plates 63 are symmetrically installed on both sides of the top of the vertical plate 61, and the limiting plates 63 are slidably connected to the upper surface of the frame 1. With the above arrangement, the vertical plate 61 and the folding plate 62 can cooperate to form an L-shaped clamp, which can clamp and restrict the position of the steel structure. At the same time, the limiting plates 63 are located above the frame 1, which can restrict the position of the clamping plate 6 and also support the clamping plate 6, dispersing the force on the bidirectional lead rod 3.

[0031] like Figure 1 and Figure 4 As shown: Second support plates 8 are installed on the upper surfaces of both ends of the frame 1, and the bidirectional screw 3 is installed between the two second support plates 8; the above arrangement facilitates the installation of the bidirectional screw 3, so that the bidirectional screw 3 can drive the clamping plate 6 to move.

[0032] like Figure 4 As shown: A drive motor 4 or a handle is installed on a second support plate 8 to drive the bidirectional lead screw 3 to rotate; with the above settings, the drive motor 4 or the handle can drive the bidirectional lead screw 3 from the outside. When the hoisting environment is not convenient to use the drive motor 4, the bidirectional lead screw 3 can be manually driven to rotate by the handle.

[0033] like Figure 1 As shown: Multiple hooks 2 are symmetrically installed on the upper surface of the frame 1; with the above arrangement, the hooks 2 are rotatably connected to the base, and the base is fixedly connected to the frame 1, so that the device can be lifted more conveniently through the multiple hooks 2.

[0034] Working principle: First, the device is moved above the steel structure by a crane. Then, the drive motor 4 drives the double-headed screw 3 to rotate. The rotation of the double-headed screw 3 can move the two clamping plates 6. The clamping plates 6 initially restrict the position of the steel structure. Then, the workers adjust the pressure plate 7 according to whether the steel structure is I-shaped or steel pipe. When it is I-shaped, the two straight plates 72 on the pressure plate 7 are aligned with the upper surface of the I-shaped steel, and the threaded rod 9 is rotated to move the pressure plate 7 downward. In this way, the position of the I-shaped steel is restricted by the straight plates 72 and the clamping plates 6.

[0035] When the steel pipe is used, the arc plate 71 on the pressure plate 7 is aligned with the outer side of the steel pipe, and the threaded rod 9 is rotated to move the pressure plate 7 downward, thereby restricting the position of the I-shaped steel through the arc plate 71 and the clamping plate 6.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
