Description

Technical Field

[0001] This utility model relates to the field of steel welding technology, specifically a multi-angle adjustable auxiliary mechanism for steel structure installation. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. In some industrial plants and warehouses, frame structures composed of welded square tubes are widely used. Square tubes have high strength and stability, and can be assembled into large frames through welding to support the roof, walls, and other structural elements of buildings. For example, the main frame of some modern logistics warehouses is welded from a large number of square tubes, which can withstand a large load and ensure the safe use of the warehouse. Usually, most steel structure frames are supported by diagonal braces during assembly. When assembling the diagonal braces, it is very inconvenient for one operator to hold the steel pipe and align it with the fixed frame, and then another operator to weld it. Furthermore, the operator's hands become fatigued after holding the steel pipe for a long time, which continuously reduces work efficiency and increases labor costs. Moreover, when welding cross steel pipes for a long time, the operator's hands are prone to shaking after fatigue, which can lead to inconsistent angles between the two steel pipes and reduce the aesthetics of the structure. Summary of the Invention

[0003] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide a multi-angle adjustable auxiliary mechanism for steel structure installation.

[0004] The specific solution of this utility model is as follows: a multi-angle adjustable auxiliary mechanism for steel structure installation, including a first sleeve, an arc-shaped groove on the circumferential surface of the first sleeve, a first fixing structure installed on the surface of the arc-shaped groove, the first fixing structure including a first angle steel movably installed on the circumferential surface of the first sleeve, a movable screw fixed at the inner angle of the first angle steel, the other end of the movable screw passing through the arc-shaped groove and threaded with a nut, the movable screw being movable along the arc-shaped groove, a second angle steel connected to the top of the first angle steel, the inner angle of the second angle steel facing the first angle steel to form an F-shaped structure, the top of the second angle steel threaded with a first fixing screw, the first fixing screw being used to clamp the steel pipe between the first angle steel and the second angle steel, a second fixing structure installed on the circumferential surface of the first sleeve, the second fixing structure including a third triangular steel fixedly installed on the circumferential surface of the first sleeve, a fourth angle steel connected to the top of a third angle steel, the inner angle of the fourth angle steel facing the third angle steel to form an F-shaped structure, the top of the fourth angle steel threaded with a second fixing screw, the third angle steel being symmetrically arranged opposite the first angle steel, so that the first fixing structure and the second fixing structure are symmetrically arranged.

[0005] According to the above technical solution, the auxiliary mechanism is fixed on the fixed frame by the second fixed structure, and then another fixed frame is placed between the first angle steel and the second angle steel and fixed by the first fixed screw. Then the position of the first angle steel on the circumferential surface of the first sleeve is adjusted, and finally the angle is fixed by the nut to carry out the welding work.

[0006] Furthermore, wear-resistant blocks are installed at the bottom of the first and second fixing screws, and the wear-resistant blocks are made of rubber.

[0007] According to the above technical solution, the anti-wear block can effectively reduce the damage to the surface of the fixing frame caused by the fixing screw during fixing, and at the same time, it can also play an anti-slip role.

[0008] Furthermore, a second sleeve is fitted onto the surface of the movable screw, and the second sleeve is located on one side of the nut.

[0009] According to the above technical solution, the second sleeve improves the ease of use of the nut.

[0010] Furthermore, the arc-shaped groove has a semi-circular structure, allowing the first angle steel to be adjusted 180°.

[0011] According to the above technical solution, the semi-circular structure allows the first angle steel to be adjusted up to 180° along the circumference.

[0012] Compared with the prior art, this utility model has the following advantages: In the multi-angle adjustable auxiliary mechanism for steel structure installation, the first angle steel moves in the arc groove on the circumferential surface of the first sleeve through the movable screw, so that the auxiliary mechanism can achieve multi-angle adjustment and improve its adaptability. It not only reduces the workload of workers, but also improves work efficiency. At the same time, mechanical fixing can avoid the angle error caused by the shaking of traditional hand-held steel pipe welding, and can effectively ensure the uniformity of the angle of the steel pipes on both sides when welding cross steel pipes, thereby improving the aesthetics of the frame structure.

[0017] See Figure 1-3This embodiment is a multi-angle adjustable auxiliary mechanism for steel structure installation. A first sleeve 1 is used to install a first fixed structure and a second fixed structure. An arc-shaped groove 2 is provided on the circumferential surface of the first sleeve 1. A first fixed structure is installed on the surface of the arc-shaped groove 2. The first fixed structure includes a first angle steel 3 movably installed on the circumferential surface of the first sleeve 1. A movable screw 4 is welded to the inner angle of the first angle steel 3. The other end of the movable screw 4 passes through the arc-shaped groove 2 and is threadedly connected to a nut 5. The movable screw 4 can move along the arc-shaped groove 2 to adjust the position of the first angle steel 3. A second angle steel 6 is welded to the top of the first angle steel 3. The inner angle of the second angle steel 6 faces the first angle steel 3, forming an F-shape. A first fixed screw is threaded to the top of the second angle steel 6. Rod 7, the first fixing screw 7 is used to clamp the steel pipe between the first angle steel 3 and the second angle steel 6. The first fixing structure is used to fix the steel pipe to be welded and adjust it at the same time. The second fixing structure is installed on the circumferential surface of the first sleeve 1. The second fixing structure includes a triangular steel 8 welded to the circumferential surface of the first sleeve 1. A fourth angle steel 9 is welded to the top of the third angle steel 8. The inner angle of the fourth angle steel 9 faces the third angle steel 8 to form an F-shaped structure. The top of the fourth angle steel 9 is threadedly connected to the second fixing screw 10. The third angle steel 8 is located opposite the first angle steel 3 and is symmetrically arranged, so that the first fixing structure and the second fixing structure are symmetrically arranged. The second fixing structure is used to fix the entire auxiliary mechanism on the fixed frame.

[0018] Furthermore, the bottom of the first fixing screw 7 and the second fixing screw 10 are fixedly bonded with anti-wear blocks 11, which are made of wear-resistant rubber material, so that the surface of the steel pipe can be effectively prevented from being damaged when fixing it.

[0019] Furthermore, a second sleeve 12 is fitted on the surface of the movable screw 4. The second sleeve 12 is located on one side of the nut 5 and inside the inner ring of the first sleeve 1, so that when the nut 5 moves, it pushes the second sleeve 12 to rub against the first sleeve 1 to achieve the effect of fixing the first angle steel 3.

[0020] Furthermore, the semi-circular structure of the arc groove 2 allows the first angle steel 3 to be adjusted up to 180°.

[0021] The working principle of this embodiment is as follows: In use, first align the opening between the third angle steel 8 and the fourth angle steel 9 with the fixed frame, and then clamp and fix the frame by rotating the second fixing screw 10. Then, place the steel pipe to be fixed into the opening between the first angle steel 3 and the second angle steel 6, and clamp and fix the steel pipe by rotating the first fixing screw 7. Then, move the first angle steel 3 to move the movable screw 4 in the arc groove 2, thereby adjusting the position of the first angle steel 3 on the circumferential surface of the first sleeve 1 to change the angle of the steel pipe. When the steel pipe reaches the welding angle, the nut is rotated to achieve the fixing effect, and then the steel pipe can be welded. If the angle needs to be adjusted again, simply loosen the nut 5 to make the corresponding adjustment.
