Technical Field
[0001] This utility model relates to the field of truss hoisting technology, and in particular to an auxiliary tool for hoisting steel pipe trusses. Background Technology
[0002] In recent years, with the continuous development of my country's building technology, tubular trusses have been increasingly widely used in industrial plants, public stadiums, and other places. Their proportion in buildings is increasing, and significant breakthroughs have been achieved in steel pipe structures. Tubular truss structures offer advantages such as good overall performance, high torsional stiffness, beautiful appearance, good structural stability, high roof stiffness, and cost reduction.
[0003] Currently, during construction, trusses are typically transported using steel wire ropes to improve safety and stability in the air. These wire ropes are made of high-strength manganese steel, possessing extremely high load-bearing capacity and wear resistance. They are usually used in conjunction with hooks or clamps to connect the crane and the steel pipe truss being hoisted.
[0004] The auxiliary tools for hoisting steel pipe trusses have the following drawbacks. Although this method can ensure a certain level of safety during hoisting, the use of wire ropes to bind the truss results in direct contact between the wire ropes and the truss surface. If the wire ropes lack sufficient wear resistance, they may break. Furthermore, during the process of suspending at a high altitude, the downward gravity of the truss still results in insufficient stability of the wire rope installation, which can easily lead to the truss shifting its center of gravity during hoisting and causing it to fall from a height. Therefore, an auxiliary tool for hoisting steel pipe trusses is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an auxiliary tool for hoisting steel pipe trusses, which aims to improve the existing technology of using steel wire ropes to bind trusses. In this case, the steel wire ropes will be in direct contact with the truss surface, and the steel wire ropes have insufficient wear resistance and may break.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel pipe truss hoisting auxiliary tool, comprising a left semi-circular plate, a right semi-circular plate, a threaded column, and a hexagonal nut.

A limit rod is fixedly connected to the bottom outer wall of the adjusting plate, and a compression spring is fixedly connected to the top outer wall of the adjusting plate. A limit hole is provided on the right outer wall of the right semi-circular plate.

[0008] As a further description of the above technical solution: there are two lifting rings, which are respectively fixedly connected to the top outer walls of the left and right semi-circular plates.
[0009] As a further description of the above technical solution: the hexagonal nut is snapped into the inner wall of the hexagonal groove, and the top and bottom sides of the adjusting plate are fixedly connected with frosted pads.

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by setting up structures such as lifting rings, hexagonal grooves, and adjusting plates, multiple sets are adjusted according to the span of the steel pipe truss to provide auxiliary clamping, fixing support, and orientation positioning. At the same time, it prevents the fixing parts from loosening during hoisting, thereby improving the stability during the hoisting process. In addition, anti-slip glue or anti-slip coating is applied to the semi-circular plate and lifting rings, thereby greatly increasing the surface friction and wear resistance and reducing wear.
[0016] 2. In this utility model, by setting structures such as insert rods, threaded caps, and snap-fit rods, the hinge points between the semi-arc plates are limited to prevent separation and failure of the semi-arc plate clamping and fixing, which would lead to malfunctions during hoisting. At the same time, it is convenient to replace and disassemble worn and damaged semi-arc plates, reducing the cost of overall replacement. Attached Figure Description

Detailed Implementation
[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 1-3 This utility model provides an embodiment of a steel pipe truss hoisting auxiliary tool, including a left semi-circular plate 1, a right semi-circular plate 2, a threaded column 3, and a hexagonal nut 4. A stabilizing mechanism 5 and an auxiliary mechanism 6 are provided on the left semi-circular plate 1. The stabilizing mechanism 5 includes a lifting ring 51, which is fixedly connected to the top outer wall of the left semi-circular plate 1. A hexagonal groove 52 is provided on the left outer wall of the left semi-circular plate 1 to limit the hexagonal nut 4. A sliding groove 53 is provided on the right inner wall of the threaded column 3. Adjusting plates 54 are slidably connected to the left and right inner walls of the sliding groove 53. A limit rod 55 is fixedly connected to the bottom outer wall of the adjusting plate 54. A compression spring 56 is fixedly connected to the top outer wall of the adjusting plate 54 to generate a continuous thrust on the adjusting plate 54. A limit hole 57 is provided on the right outer wall of the right semi-circular plate 2.
[0025] Reference Figures 2-4There are two lifting rings 51, which are fixedly connected to the top outer walls of the left semi-arc plate 1 and the right semi-arc plate 2 respectively. By applying anti-slip glue or anti-slip coating to the inner walls of the lifting rings 51 and the left semi-arc plate 1 and the right semi-arc plate 2 respectively, the surface friction and wear resistance are greatly increased, and the wear is reduced. The hexagonal nut 4 is snapped into the inner wall of the inner ring of the hexagonal groove 52. The top and bottom outer walls of the adjusting plate 54 are fixedly connected with abrasive pads. By setting abrasive pads, the friction of the surface of the adjusting plate 54 is increased, reducing the slippage of the operator. The end of the compression spring 56 away from the adjusting plate 54 is fixedly connected to the top inner wall of the slide groove 53. The limiting rod 55 is snapped into the inner wall of the inner ring of the limiting hole 57. The right semi-arc plate 2 is hinged to the bottom outer wall of the left semi-arc plate 1. The threaded post 3 penetrates the left inner wall of the left semi-arc plate 1. The hexagonal nut 4 is threadedly connected to the side outer wall of the threaded post 3.
[0026] Reference Figures 3-4 The auxiliary mechanism 6 includes a plug rod 61, which penetrates the bottom inner wall of the left semi-arc plate 1. A threaded cap 62 is threadedly connected to the outer side wall of the plug rod 61. A lever 63 is slidably connected to the bottom inner wall of the left semi-arc plate 1. A locking rod 64 is fixedly connected to the bottom outer wall of the lever 63. The locking rod 64 is used to lock and limit the plug rod 61, preventing the plug rod 61 from falling off when the threaded cap 62 disengages. A telescopic spring 65 is fixedly connected to the top outer wall of the lever 63, which generates a continuous pushing force on the lever 63. The threaded cap 62 penetrates the bottom inner wall of the right semi-arc plate 2. The end of the telescopic spring 65 away from the lever 63 is fixedly connected to the inner wall of one side of the left semi-arc plate 1. A wear-resistant pad is fixedly connected to the outer side wall of the locking rod 64, which increases the wear resistance of the locking rod 64 and prevents it from breaking due to severe wear. The locking rod 64 is locked to the top inner wall of the plug rod 61.
[0027] Working principle: The steel pipe truss is wrapped by the left and right semi-circular plates 1 and 2. Then, by twisting the hexagonal nuts 4 and threaded columns 3, the steel pipe truss is clamped and fixed by the left and right semi-circular plates 1 and 2. Lifting is then assisted by lifting rings 51. Typically, two lifting rings 51 are installed on each side of the steel pipe truss, forming a set. One set is generally used for steel pipe trusses with smaller spans, while more sets are used for larger spans, depending on the situation. This improves stability during lifting, creating multiple support points and ensuring the stability of the support points during the lifting process. When the auxiliary hoisting tool comes into contact with the steel pipe truss, it greatly reduces material wear. At the same time, during the hoisting process, the hexagonal nut 4 or the threaded column 3 is prone to rotation. By inserting the limiting rod 55 into the corresponding limiting hole 57, the rotation of the threaded column 3 is restricted. Meanwhile, the hexagonal nut 4 is locked in the hexagonal groove 52 to restrict rotation. When the left half-arc plate 1 or the right half-arc plate 2 is damaged, the locking rod 64 is pulled out from the insertion rod 61 by pulling the lever 63. Then, the threaded nut 62 is rotated to separate from the insertion rod 61. Then, the insertion rod 61 is pulled out from the inner wall of the left half-arc plate 1 and the right half-arc plate 2, so that the single worn and damaged half-arc plate can be easily replaced.
[0028] 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.
