Description

Technical Field

[0001] This utility model belongs to the field of steel structure welding and processing technology, and specifically relates to a steel structure welding auxiliary device. Background Technology

[0002] Steel structures are structural forms that can bear and transmit loads by connecting components. They have comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in terms of "height, size, and lightness", and therefore have been rationally and widely used in the field of building engineering.

[0003] In the production, processing, or construction of steel structures, welding is required to connect steel components into a spatial frame structure with sufficient strength, rigidity, and stability to support equipment, pipelines, or platforms. Tooling fixtures are needed to secure the components during welding. However, steel components, including angle steel, channel steel, I-beams, H-beams, and steel pipes, have the following drawbacks in actual processing: (1) Compared with square tubes, I-beams, etc., round tubes are difficult to share a single fixture due to their different shapes. If a set of fixtures is prepared for each type of component, the cost will increase significantly. (2) The joint left after welding will not fit the support surface after rotation, and the component will shake when welding again, which will affect the welding quality of the steel structure. (3) The shape of the fixture is too conservative or based on experience, resulting in excessive steel consumption and not economical.

[0004] Therefore, it is necessary to design a steel structure welding auxiliary device to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a steel structure welding auxiliary device that can clamp and fix components of different sizes and types. It has good stability and strong practicality, which greatly improves the welding efficiency of workers and reduces costs.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A steel structure welding auxiliary device includes a base plate, a first horizontal support frame, a second horizontal support frame, a first arc support frame, a second arc support frame, a third arc support frame, a fourth arc support frame, a hydraulic device, and clamping blocks. The hydraulic device includes a control box and four hydraulic stations. The first, second, third, and fourth arc support frames are respectively installed above the four hydraulic stations. The first, second, third, and fourth arc support frames are sequentially arranged above the base plate. The first horizontal support frame is located between the first and second arc support frames, and the second horizontal support frame is located between the third and fourth arc support frames. The upper surfaces of the first and second horizontal support frames are provided with longitudinal sliding grooves. The clamping blocks are located at both ends of the longitudinal sliding grooves. Rotating handles are provided on the outer sides of the first and second horizontal support frames and connected to the outer sides of the clamping blocks via screws.

[0007] As an improvement of this utility model, a welding slag collection tray is provided on the base plate between the second arc support frame and the third arc support frame.

[0008] As an improvement of this utility model, the first arc support frame, the second arc support frame, the third arc support frame, and the fourth arc support frame are coaxial in the X-axis direction.

[0009] As an improvement of this utility model, the motors of the four hydraulic stations are synchronous motors.

[0010] As an improvement of this utility model, two clamping blocks are provided on the upper surface of both the first horizontal support frame and the second horizontal support frame, and the two clamping blocks are symmetrically distributed.

[0011] The beneficial effects of this utility model are as follows: (1) Angle steel, channel steel, I-beam steel, and H-beam steel can be laid flat on the first horizontal support frame and the second horizontal support frame, and welded after being clamped together; when it is necessary to weld round pipes, four hydraulic stations raise the arc support frame, and two round pipes are placed on both sides respectively. The welding point is between the second arc support frame and the third arc support frame. The clamping block can also clamp the side of the round pipe, ensuring that it can weld components of different sizes and types, and has a wide range of applications; when welding angle steel, channel steel, I-beam steel, and H-beam steel, the arc support frame falls down, and its height does not exceed the height of the horizontal support frame, and they do not affect each other; (2) The welding point is between the second and third circular arc support frames and does not contact the support surface, so it will not cause the components to shake and improve the welding quality of the steel structure. (3) The horizontal support frame and the arc support frame described in this utility model are arranged at intervals with gaps between them, which reduces the amount of steel used and the manufacturing cost.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0017] As shown in the figure, the steel structure welding auxiliary device of this utility model includes a base plate 1, a first horizontal support frame 2, a second horizontal support frame 3, a first arc support frame 4, a second arc support frame 5, a third arc support frame 6, a fourth arc support frame 7, a hydraulic device, and a clamping block 8. The hydraulic device includes a control box 9 and four hydraulic stations 10. The first arc support frame 4, the second arc support frame 5, the third arc support frame 6, and the fourth arc support frame 7 are respectively installed above the four hydraulic stations 10. The first arc support frame 4, the second arc support frame 5, the third arc support frame 6, and the fourth arc support frame 7 are respectively installed above the four hydraulic stations 10. The third arc support frame 6 and the fourth arc support frame 7 are sequentially arranged above the base plate 1. The first horizontal support frame 2 is arranged between the first arc support frame 4 and the second arc support frame 5. The second horizontal support frame 3 is arranged between the third arc support frame 6 and the fourth arc support frame 7. The upper surfaces of the first horizontal support frame 2 and the second horizontal support frame 3 are provided with longitudinal sliding grooves 11. The clamping blocks 8 are arranged at both ends of the longitudinal sliding grooves 11. The outer sides of the first horizontal support frame 2 and the second horizontal support frame 3 are provided with rotating handles 12, which are connected to the outer side of the clamping blocks 8 by screws.

[0018] The steel structure welding auxiliary device described in this utility model is capable of distinguishing between welding round pipes and square components: (1) When it is necessary to weld square components (angle steel, channel steel, I-beam, H-beam), place the two components to be welded flat on the first horizontal support frame 2 and the second horizontal support frame 3, with the joint point located between the second arc support frame and the third arc support frame. Then manually tighten the rotating handle 12 so that the two sets of clamping blocks 8 move towards the middle and finally clamp the components. After clamping, start welding. At this time, the four arc support frames are in the lowered state, and the height of the arc support frames is lower than the height of the horizontal support frames, so the square components can be welded normally. (2) When welding is required on the round pipe, the four hydraulic stations 10 are started to raise the four arc support frames (higher than the height of the horizontal support frame). The four arc support frames are at the same height and coaxial. Then, the two round pipes to be welded are placed flat at both ends. The first round pipe is placed on the first arc support frame 4 and the second arc support frame 5, and the second round pipe is placed on the third arc support frame 6 and the fourth arc support frame 7. The joint point is located between the second arc support frame 5 and the third arc support frame 6. Similarly, the rotating handle 12 is manually tightened so that the two sets of clamping blocks 8 move towards the middle and finally clamp the round pipe. Welding begins after clamping.

[0019] This device uses little steel, has low manufacturing cost, can weld components of different sizes and types, has a wide range of applications, and the welding points do not contact the supporting surface, so the components will not shake after rotation, ensuring the welding quality of the steel structure.

[0020] This utility model has a slag collection tray 13 on the base plate between the second arc support frame 5 and the third arc support frame 6 for collecting welding slag.

[0021] The motors of the four hydraulic stations 10 described in this utility model are synchronous motors, and are uniformly controlled by the control box 9. The four hydraulic stations 10 have the same pressure and the same lifting height.

[0022] The first horizontal support frame 2 and the second horizontal support frame 3 of this utility model are each provided with two clamping blocks 8 on their upper surfaces. The two clamping blocks 8 are symmetrically distributed. The height of the clamping blocks 8 is constant, but they can only move longitudinally. They can clamp all components, and manual clamping will ensure that the axis of the components will not be deviated.

[0023] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
