Description

Technical Field

[0001] This utility model relates to the field of spark welding devices, specifically a spark welding device for butt welding of steel beams and steel columns. Background Technology

[0002] With the country's strong advocacy for green prefabricated buildings in recent years, the development of steel structure buildings has become increasingly rapid. At the same time, some common problems in steel structure construction have become more and more prominent. In particular, when steel (frame) beams are butt-welded to steel (frame) column brackets at joints in steel or steel-concrete structures, a large number of sparks are generated and splashed from high altitudes to the ground, endangering the safety of ground workers and ground items, and easily causing fires.

[0003] A search revealed that Chinese Patent Publication No. CN 222448907 U relates to a novel welding slag receiving device, belonging to the technical field of welding slag receiving devices. It includes a welding hopper, one end of which is fitted against the outer peripheral wall of a steel column, and the other end of which is equipped with a lifting device. The welding hopper is connected to a steel beam via the lifting device, and is located below the weld joint between the steel column and the steel beam. This application has the effect of facilitating the collection of welding slag generated during the welding of steel columns and beams.

[0004] The spark receiving device in the aforementioned patent still has certain shortcomings. Since most existing spark receiving basins are simply made and easily deformed, and lack effective hanging measures, during the spark receiving process, the accumulation of local welding slag and poor heat dissipation often cause the spark receiving basin to overheat and burn through the iron sheet, or to be twisted and deformed significantly, or even scrapped. Furthermore, in windy weather, the welding slag and spark receiving basin are easily blown away, resulting in poor spark receiving effect and wasting manpower, material resources and time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spark welding device for butt welding of steel beams and steel columns. This solves the problems of existing fire-receiving basins being mostly crudely made, easily deformed, and lacking effective hanging measures. Consequently, during fire-receiving use, the accumulation of local welding slag and poor heat dissipation often cause the fire-receiving basin to overheat, burn through the iron sheet, or become severely twisted and deformed, or even become unusable. Furthermore, in windy weather, welding slag and the fire-receiving basin are easily blown away, resulting in poor fire-receiving effect and wasting manpower, resources, and time.

[0006] This utility model provides the following technical solution: a spark welding device for butt welding of steel beams and steel columns, including two steel columns, with steel beams at the top of the two steel columns. The steel columns and steel beams are connected by two symmetrically arranged connecting steel plates. The connecting steel plates are connected to the steel columns and steel beams respectively by a number of through-inserted fixing bolts. A spark-receiving hopper is provided at the bottom of the joint between the steel beams and the connecting steel plates. A hook is provided at the top of the spark-receiving hopper. The bottom end of the hook is connected to the spark-receiving hopper by a connecting steel wire. A spark-receiving auxiliary component is provided at the top of the spark-receiving hopper.

[0007] The spark receiving auxiliary assembly includes two sets of spark guide plates symmetrically arranged on both sides of the top of the spark receiving bucket. Each spark guide plate has a first connecting ring on its side. A fixing collar is fitted on the hook. A fastening bolt is threaded into the side of the fixing collar. Second connecting rings are evenly arranged around the bottom of the fixing collar. The second connecting rings are connected to the first connecting rings by a connecting rope. A fixing connecting plate is fixed around the top of the spark receiving bucket. Both ends of the fixing connecting plate are rotatably connected to a rotating shaft.

[0008] Preferred technical solution 1: Each of the connecting rotating shafts is connected to a rotating connecting plate, and the ends of the rotating connecting plates are fixedly connected to the side of the bottom end of the spark guide plate.

[0009] Preferred technical solution 2: The fire-receiving hopper is in the shape of an inverted pyramid, and the top of the fire-receiving hopper is fixed by staggered steel bars.

[0010] Preferred technical solution three: The longitudinal section of each of the four spark guide plates is trapezoidal.

[0011] This solution can effectively expand the area around the four spark guide plates that can receive sparks generated during the welding process.

[0012] Preferred technical solution four: The end of the fastening bolt is provided with a connecting block that facilitates rotation.

[0013] This solution makes it easier for users to rotate the fastening bolts.

[0014] Preferred technical solution five: The spark guide plates are all located on the top of the fixed connecting plate, and the top of the fixed connecting plate is arc-shaped.

[0015] This design allows the spark guide plate to rotate more smoothly on top of the fixed connection plate without being obstructed by the top of the fixed connection plate.

[0016] Compared with the prior art, this utility model provides a spark welding device for butt welding of steel beams and steel columns, which has the following beneficial effects:

[0017] (1) This utility model has a fire-catching bucket at the bottom of the welding joint between the steel column and the steel beam. The fire-catching bucket is equipped with a spark-catching auxiliary component and a hook. The hook is welded to the bottom of the welding operation. The hook and the fire-catching bucket are connected by a connecting steel wire. The spark guide plate in the spark-catching auxiliary component can be deflected and unfolded, thereby increasing the spark-catching area at the top of the fire-catching bucket. This allows all the sparks generated during the welding operation to be collected. The device is more robust and durable than the traditional fire-catching basin. It is also more aesthetically pleasing and has a larger fire-catching capacity. The welding slag is not easy to spill. It is easy for workers to operate and can effectively improve the efficiency of welding slag removal. The device is also compact and lightweight, allowing users to use local materials. It is quick to install, highly practical, and easy to operate. It can well meet the requirements of welding fire for the butt welding of steel beams and steel column brackets on site. It is easy to remove and can be reused multiple times. It has low loss, is green and environmentally friendly, safe and reliable, saves labor, is suitable for large-scale promotion and application, has low production cost, and high economic benefits.

[0025] Please see Figure 1-5 ,

[0026] Example 1: A spark welding device for butt welding of steel beams and steel columns includes two steel columns 1. A steel beam 2 is mounted on the top of each steel column 1. The steel columns 1 and steel beam 2 are connected by two symmetrically arranged connecting steel plates 3. Several through-bolts 4 are inserted into the connecting steel plates 3 and connected to the steel columns 1 and steel beam 2 respectively. A spark-receiving hopper 5 is provided at the bottom of the joint between the steel beam 2 and the connecting steel plate 3. A hook 6 is provided at the top of the spark-receiving hopper 5. The bottom end of the hook 6 is connected to the spark-receiving hopper 5 via a connecting steel wire 7. A spark-receiving auxiliary component 8 is provided at the top of the spark-receiving hopper 5.

[0027] The spark receiving auxiliary assembly 8 includes two sets of spark guide plates 801 symmetrically arranged on both sides of the top of the spark receiving hopper 5. Each spark guide plate 801 has a first connecting ring 802 on its side. A fixing collar 803 is fitted on the hook 6. A fastening bolt 804 is threaded into the side of the fixing collar 803. Second connecting rings 805 are evenly arranged around the bottom of the fixing collar 803. The second connecting rings 805 and the first connecting rings 802 are connected by a connecting rope 806. A fixing connecting plate 807 is fixed around the top of the spark receiving hopper 5. A connecting rotating shaft 808 is rotatably arranged at both ends of the fixing connecting plate 807. A rotating connecting plate 809 is connected to each connecting rotating shaft 808. The ends of the rotating connecting plates 809 are fixedly connected to the side of the bottom of the spark guide plate 801.

[0028] The fire-receiving bucket 5 is shaped like an inverted pyramid, and the top of the fire-receiving bucket 5 is fixed by staggered steel bars.

[0029] Example 2: The difference between this example and Example 1 is that the longitudinal sections of the four spark guide plates 801 are all trapezoidal.

[0030] This effectively expands the area for receiving sparks generated during the welding process by enclosing the four spark guide plates 801.

[0031] Example 3: The difference between this example and Example 1 is that the end of the fastening bolt 804 is provided with a connecting block that facilitates rotation.

[0032] This makes it easier for users to rotate the 804 fastening bolt.

[0033] Example 4: The difference between this example and Example 1 is that the spark guide plate 801 is located on the top of the fixed connecting plate 807, and the top of the fixed connecting plate 807 is arc-shaped.

[0034] This allows the spark guide plate 801 to rotate more smoothly on top of the fixed connecting plate 807, without being obstructed by the top of the fixed connecting plate 807.

[0035] In this embodiment, since most existing fire-receiving basins are crudely made, easily deformed, and lack effective hanging measures, during the fire-receiving process, the accumulation of local welding slag and poor heat dissipation often cause the fire-receiving basin to overheat and burn through the iron sheet, or to be twisted and deformed significantly, or even scrapped. Furthermore, in windy weather, the welding slag and the fire-receiving basin are easily blown away, resulting in poor fire-receiving effect and wasting manpower, material resources, and time.

[0036] In summary, when a user needs to perform welding work at the junction of steel column 1 and steel beam 2, the user can first weld the hook 6 to the bottom of the junction, and then tie the connecting wire 7 to the bottom end of the hook 6. The other end of the connecting wire 7 is tied to the steel bar set on the top of the fire-receiving bucket 5, so that the fire-receiving bucket 5 can be stably set at the bottom of the welding point.

[0037] Next, the user can rotate the spark guide plate 801 in the spark auxiliary assembly 8 to unfold the four spark guide plates 801 and surround the side of the top of the spark receiving hopper 5. Then, by rotating the fastening bolt 804 on the fixing collar 803, the fixing collar 803 is fixed to the hook 6. By binding the connecting rope 806 to the second connecting ring 805, and the other end of the connecting rope 806 is bound to the first connecting ring 802 on the side of each spark guide plate 801, the spark guide plate 801 can be kept stable under the pull of the connecting rope 806. The unfolded spark guide plate 801 can effectively increase the spark receiving area at the top of the spark receiving hopper 5, so that the sparks falling from the weld joint of the steel column 1 and the steel beam 2 can be quickly collected into the spark receiving hopper 5.

[0038] Compared to traditional fire-receiving basins, this device is more robust and durable, aesthetically pleasing, and has a large fire-receiving capacity. It also prevents slag leakage, is easy for workers to operate, and effectively improves welding slag removal efficiency. Its compact structure and light weight allow users to easily utilize locally available materials, enabling rapid installation, strong practicality, and simple operation. It perfectly meets the requirements for butt welding of steel beams and steel column brackets on-site. Furthermore, it is easy to remove, can be reused multiple times, has low wear and tear, is environmentally friendly, safe and reliable, saves labor, is suitable for large-scale application, has low manufacturing costs, and offers high economic benefits.
