Description

Technical Field

[0001] This utility model relates to the field of tubular steel structure welding technology, and in particular to a tubular steel structure welding device. Background Technology

[0002] In the construction process of building engineering, a large number of steel components are used for erecting scaffolding, building frames and reinforcing structures. Among these steel components, tubular steel components of various sizes play an important role. Depending on the usage, the lengths of the tubular steel components may not match, so welding equipment is needed to weld the tubular steel components together.

[0003] For example, a welding device for tubular steel components in building engineering, with publication number "CN114952123A", uses a support mechanism for support. As the tubular steel component moves to the left, the elastic plate above the connector exerts pressure on the inner wall of the tubular steel component, providing initial fixation. After the tubular steel component is in place, the drive component A drives the drive shaft to rotate. Through the engagement of the threads, the moving component can move the connector to the right, increasing the deformation of the elastic plate and thus increasing the force exerted by the support plate on the inner wall of the tubular steel component. However, this device, which uses an elastic plate to fix the tubular steel component, is prone to displacement during welding, resulting in substandard welded tubular steel components. Furthermore, the positions of the support mechanisms on both sides cannot be adjusted, limiting its applicability to tubular steel components of a specific diameter. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing a tubular steel structure welding device. Multiple sliders can hold the tubular steel structure body in place, thereby reducing defects after welding. At the same time, the combination of the insertion port and the slot improves the applicability of the equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This tubular steel structure welding device includes a base and a support plate. The support plate is installed on both sides above the base. Multiple tubular steel structure bodies are provided above the base. The lower part of each tubular steel structure body is in contact with a roller. The rollers are all installed inside the bracket. An adjustment structure is provided below the bracket. The inner wall of the support plate is fixedly connected to the rotating block through bearings. The rotating block is provided with a limiting structure inside. The left end of the rotating block is fixedly connected to the end of the output shaft of the servo motor.

[0006] This setting allows the servo motor to drive the fixed tubular steel structure to rotate, facilitating welding.

[0007] To further improve the design, the end of the servo motor is threadedly connected to the support plate via bolts.

[0008] This setting: The servo motor is connected to the support plate via bolts, which facilitates maintenance.

[0009] In a further improvement, the limiting structure includes a slider, with locking blocks fixedly connected to both sides of the slider. The locking blocks, cylinders, and the outer wall of the slider are all slidably connected to the slide groove. A cylinder is fixedly connected to the outer side of the slider, and the outer wall of the cylinder is threadedly connected to an anti-loosening nut.

[0010] This setting allows you to fix the tubular steel structure in place using multiple sliders, reducing the likelihood of misalignment.

[0011] To further improve the design, all the grooves are machined on the inner wall of the rotating block.

[0012] This setting: The chute can serve as a guide.

[0013] In a further improvement, the adjustment structure includes insert blocks, the outer walls of which are all inserted into slots, multiple slots are machined on the inner wall of the base, and the top of each insert block is fixedly connected to a bracket.

[0014] This feature allows for free adjustment of the bracket's position through the combination of multiple inserts and slots, enabling it to be used with tubular steel structures of different diameters.

[0015] The beneficial effects of this utility model are as follows: By cooperating with the rotating block and the limiting structure, multiple anti-loosening nuts are loosened and the cylinder is held. The cylinder is moved manually, and the movement of the cylinder causes the slider and the locking block to slide along the inner wall of the groove. When the outer wall of the slider is pressed against the inner wall of the tubular steel structure body, the operator tightens multiple anti-loosening nuts to restrict the movement of the slider. This reduces the possibility of the tubular steel structure body shifting during welding, which could lead to the tubular steel structure body being unqualified after welding.

[0016] By combining the base and the adjustment structure, the inserts under multiple supports are inserted into corresponding slots according to the diameter of the tubular steel structure body, so that the spacing between the two supports can be adjusted. Within a certain range, it can be used with tubular steel structures of different diameters, thus improving the applicability of the equipment. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1-5 In this embodiment, a tubular steel structure welding device includes a base 1 and a support plate 3. Support plates 3 are installed on both sides above the base 1. Multiple tubular steel structure bodies 5 are provided above the base 1. The lower part of each tubular steel structure body 5 is in contact with a roller 9. The roller 9 is installed inside a bracket 6. An adjustment structure 2 is provided below the bracket 6. The inner wall of the support plate 3 is fixedly connected to a rotating block 8 through bearings. Each rotating block 8 is provided with a limiting structure 7. The end of the left rotating block 8 is fixedly connected to the end of the output shaft of a servo motor 4. The end of the servo motor 4 is threadedly connected to the support plate 3 through bolts.

[0025] The limiting structure 7 includes a slider 701, with locking blocks 702 fixedly connected to both sides of the slider 701. The locking blocks 702, cylinders 704, and the outer wall of the slider 701 are all slidably connected to the slide groove 703. The outer side of the slider 701 is fixedly connected to the cylinders 704, and the outer wall of the cylinders 704 is threadedly connected to the anti-loosening nuts 705. By loosening multiple anti-loosening nuts 705 and holding the cylinders 704, the cylinders 704 can be manually moved. The movement of the cylinders 704 causes the slider 701 and locking blocks 702 to slide along the inner wall of the slide groove 703. When the outer wall of the slider 701 is pressed against the inner wall of the tubular steel structure body 5, the operator tightens multiple anti-loosening nuts 705 to restrict the movement of the slider 701 and reduce the possibility of the tubular steel structure body 5 shifting during welding, which could lead to the tubular steel structure body 5 being unqualified after welding.

[0026] The slide grooves 703 are all machined on the inner wall of the rotating block 8. The adjustment structure 2 includes the insert block 201. The outer wall of the insert block 201 is inserted into the slot 202. Multiple slots 202 are machined on the inner wall of the base 1. The upper part of the insert block 201 is fixedly connected to the bracket 6. The insert blocks 201 under the multiple brackets 6 are inserted into the corresponding slots 202 so that the distance between the two brackets 6 can be adjusted. Within a certain range, it can be used with tubular steel structure bodies 5 of different diameters to improve the applicability of the equipment.

[0027] Working principle:

[0028] When using tubular steel structure welding equipment:

[0029] The operator first installs the base 1 onto the welding equipment through the threaded holes at the four corners. Based on the diameter of the tubular steel structure body 5, the inserts 201 below multiple supports 6 are inserted into the corresponding slots 202 (only one set is shown in the diagram; multiple sets can be used in actual operation). Therefore, the spacing between the two supports 6 can be adjusted. Within a certain range, it can be used with tubular steel structure bodies 5 of different diameters, improving the applicability of the equipment. Then, one tubular steel structure body 5 is fitted onto the rotating block 8 on the left side and positioned on the rollers 9 of the multiple supports 6 (at this time, the support plate 3 on the right side is not installed). Then, the end of this tubular steel structure body 5 is aligned with the end of another tubular steel structure body 5 (as shown in the attached diagram). Figure 2 As shown, at this time, the tubular steel structure body 5 of the clothes drying pole is in contact with multiple rollers 9 below. Then, the operator inserts the rotating block 8 on the right support plate 3 into the right side of another tubular steel structure body 5 (as shown in the attached diagram). Figure 2 (as shown);

[0030] Afterwards, loosen multiple anti-loosening nuts 705 and hold the cylinder 704. Manually move the cylinder 704. The movement of the cylinder 704 causes the slider 701 and the locking block 702 to slide along the inner wall of the slide groove 703. When the outer wall of the slider 701 is pressed against the inner wall of the tubular steel structure body 5, the operator tightens multiple anti-loosening nuts 705 to restrict the movement of the slider 701 and reduce the possibility of the tubular steel structure body 5 shifting during welding, which could lead to the tubular steel structure body 5 being unqualified after welding.

[0031] After the two tubular steel structures 5 are fixed, the operator adjusts the welding equipment to make the welding head fit against the inner side of the two tubular steel structures 5 and the position to be welded. Then, the servo motor 4 is started (the servo motor 4 can be connected to the controller and the drive board, and the drive board can be driven to start and stop it through the button on the controller). The output shaft of the servo motor 4 rotates, which drives the rotating block 8 to rotate, which in turn drives the tubular steel structure 5 to rotate, and thus the two tubular steel structure 5 can be welded together.

[0032] After welding is completed, the operator resets the welding equipment, then loosens multiple anti-loosening nuts 705 to disengage the slider 701 from the tubular steel structure body 5, and then removes the welded steel structure body 5.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
