Description

Technical Field

[0001] The utility model relates to the field of steel component welding, in particular to a steel component welding auxiliary device. Background Technique

[0002] During the construction of steel structure buildings, bridges, towers and other projects, I-beams are widely used as the main load-bearing structural members. During the manufacturing and installation of these structures, welding of high-position I-beams is a key process, which requires welders to work at high altitudes, posing higher requirements for welding quality and safety.

[0003] Traditional welding methods rely on ladders and lift trucks to lift welders to the welding points. Although ladders are low-cost, they have obvious deficiencies in terms of operation flexibility and safety. Especially for long-term welding operations, ladders cannot provide a stable and comfortable working environment, and welders are prone to fatigue, affecting welding quality and efficiency. On the other hand, although lift trucks provide better operation height adjustment capabilities and working platforms, they are costly, and in the case of limited construction site space, frequent movement of lift trucks will reduce work efficiency and may cause construction delays due to waiting for equipment. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a steel component welding auxiliary device to solve the problem of obvious deficiencies in the operation flexibility and safety of traditional welding methods that rely on ladders and lift trucks to lift welders to the welding points.

The first clamping blocks are fixed on the surface of the bearing plate. First nut seats and second nut seats are respectively arranged on the first clamping blocks and the second clamping blocks. A screw rod is connected between the first nut seat and the second nut seat. Rotating the screw rod makes the first clamping block and the second clamping block move towards each other and clamp tightly on the I-beam.

[0006] In a preferred embodiment, the first clamping block and the second clamping block are U-shaped structure clamping blocks. The U-shaped structure clamps on the edge of the I-beam flange, and a rubber pad is arranged inside the U-shaped structure groove body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1 to 3As shown in the figure, a welding auxiliary device for steel members is provided. On the upper and lower sides of the inner surface of the bearing plate 5, first fixing frames 2 are symmetrically arranged. The first fixing frames 2 are used to be fixed on the I-beam 1. On the outer surface of the bearing plate 5, a construction seat 7 is provided. The first fixing frame 2 includes two symmetrically arranged first clamping blocks 201 and second clamping blocks 206. The first clamping blocks 201 and the second clamping blocks 206 are used to clamp on the I-beam 1. The first clamping blocks 201 are fixed on the surface of the bearing plate 5. First nut seats 202 and second nut seats 205 are respectively provided on the first clamping blocks 201 and the second clamping blocks 206. The first nut seat 202 and the second nut seat 205 are connected by a screw rod 204. By rotating the screw rod 204, the first clamping blocks 201 and the second clamping blocks 206 move relative to each other and clamp tightly on the I-beam 1.

[0022] The first fixing frame 2 is tightly fixed to the I-beam 1 through the first clamping blocks 201 and the second clamping blocks 206, ensuring the stability of the bearing plate 5 and thus providing a safe working environment for the welder.

[0023] By rotating the screw rod 204 to adjust the distance between the first clamping blocks 201 and the second clamping blocks 206, the device can be easily fixed on I-beams of different sizes, improving the versatility and adaptability of the device.

[0024] The construction seat 7 provided on the bearing plate 5 enables the welder to maintain a comfortable sitting posture during long-time operation at heights, reducing physical burden and being beneficial to improving the welding quality. The opening part of the U-shaped clamping block can fit the edge of the I-beam flange, thereby fixing the clamping block on the I-beam.

[0025] In a preferred embodiment, the first clamping blocks 201 and the second clamping blocks 206 are U-shaped structural clamping blocks. The U-shaped structures are clamped on the edges of the flanges of the I-beam 1, and rubber pads are provided inside the U-shaped structural grooves. The main purpose of designing the first clamping blocks 201 and the second clamping blocks 206 as U-shaped structures is to better adapt to the shape of the I-beam 1 and provide a stable clamping force.

[0026] The rubber pads can increase the friction coefficient between the clamping blocks and the I-beam contact surface, prevent the device from sliding due to vibration or other external forces during the welding process, and improve the operation safety.

[0027] In a preferred embodiment, a nut head 203 is provided in the middle of the screw rod 204, and the screw threads at both ends of the nut head 203 have opposite helix directions.

[0028] When the nut head 203 is rotated, due to the opposite helix directions of the threads at both ends, the first clamping blocks 201 and the second clamping blocks 206 will move at the same speed but in opposite directions. This means that when you tighten the nut head, the two clamping blocks will move towards the center simultaneously and clamp the I-beam tightly; when you loosen it in the reverse direction, they will separate outward simultaneously and release the I-beam. Such a design ensures the balanced force application of the clamping blocks and avoids instability or damage caused by unilateral force.

[0029] Using a nut head 203 to control the movement in two directions, compared with using two independent screws and nuts, this design is more compact, saves space, and simplifies the structure of the device.

[0030] In a preferred embodiment, a through hole is also provided in the radial direction on the nut head 203, and a pry bar passes through the through hole for rotating the nut head 203. There are usually through holes on the nut head 203, allowing tools such as pry bars to be inserted and rotated, which enables convenient operation even in a narrow space, improving the practicality and flexibility of the device. By inserting a pry bar into the through hole, the operator can utilize the lever principle to generate a large torque with a small force, which is particularly useful for tightening or loosening the nut head, especially in situations where a large force is required.

[0031] In a preferred embodiment, the bearing plate 5 is connected to the support cross bar 6, and a diagonal brace is also provided between the end of the support cross bar 6 and the bearing plate 5. The construction seat 7 provided on the bearing plate 5 enables the welder to maintain a comfortable sitting position during long-term operation at a height, reducing the physical burden and being beneficial to improving the welding quality. The design of the support cross bar 6 and the diagonal brace increases the overall structural stability, while ensuring the lightness and easy mobility of the device, facilitating rapid deployment on-site.

[0032] In a preferred embodiment, a welding machine carrier 9 is further provided below the bearing plate 5, and a second fixing frame 3 is provided on the welding machine carrier 9 for fixing on the I-beam 1. The welding machine carrier 9 is connected to the bearing plate 5 through at least two connecting plates 8, and both ends of the connecting plates 8 are locked to the welding machine carrier 9 and the bearing plate 5 respectively by a plurality of screws. The welding machine carrier 9 provided below the bearing plate 5 ensures the stable placement of the welding equipment, avoids the inconvenience of frequent handling of the welding machine, and improves the work efficiency.

[0033] The welding machine carrier 9 provided below the bearing plate 5 provides a stable platform for placing welding equipment such as welding machines, cables, and related tools. The welding machine carrier 9 is fixed on the I-beam 1 through the second fixing frame 3, ensuring that even in a complex construction environment, the welding equipment can remain stable and will not be displaced due to vibration or accidental collision, thereby improving the safety and efficiency of the welding operation.

[0034] The welding machine carrier 9 is connected to the bearing plate 5 through at least two connecting plates 8, and both ends of these connecting plates 8 are locked to the welding machine carrier 9 and the bearing plate 5 respectively by a plurality of screws.

[0035] In a preferred embodiment, a ladder 4 is further provided below the second fixing frame 3. The configuration of the second fixing frame 3 and the ladder 4 enables the welder not only to work at a height but also to go up and down conveniently, further enhancing the practicality of the device.

The protection scope of the present utility model shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
