Description

Technical Field

[0001] This utility model belongs to the field of high-altitude welding technology and relates to a device for preventing sparks and foreign objects from falling, specifically a device for preventing sparks and foreign objects from falling during high-altitude welding of pipes. Background Technology

[0002] In industries such as power and chemical manufacturing, rows of pipes need to be laid high in the air during production and construction. Due to the length of the pipes, installation is done in sections by welding. The pipes to be welded are hoisted into the air, aligned with the already installed pipe ends, and then welded at the pipe ends. However, during high-altitude welding, welding sparks fall downwards. Due to the dense arrangement of pipes, a large number of welding sparks are generated, which may fall onto equipment and cause fires, as well as injure people on the ground. In addition, welding rods, welding wires, and flux residue may also fall, causing safety accidents. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a device for preventing the falling of sparks and foreign objects generated during high-altitude pipe welding, thereby achieving the purpose of preventing the falling of sparks or foreign objects generated during the welding process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for preventing sparks and foreign objects from falling from high-altitude welding pipes includes a receiving tray, both ends of which are fixed to the pipe by clamps; a baffle for adhering to the pipe is fixed on one side of the receiving tray, and multiple inwardly recessed arc-shaped grooves are spaced apart on the baffle, the spacing of the arc-shaped grooves matching the spacing of the pipe, and the diameter of the arc-shaped grooves matching the diameter of the pipe.

[0005] As a limitation of this utility model, the receiving tray has 20-30mm folded edges on three sides without the baffle.

[0006] As a further limitation of this utility model, the height of the baffle is 80-100mm, and the upper edge of the baffle is aligned with the upper edge of the folded edge.

[0007] As another limitation of this utility model, the clamp includes a clamp and a connecting plate. The cross-section of the clamp is an arc-shaped groove that matches the diameter of the pipe. The connecting plate is fixed to one end of the clamp. The two ends of the baffle protrude from the receiving plate and are fixedly connected to the connecting plate by bolts.

[0008] As a limitation of this utility model, the clamp includes two clamps, which are respectively fixed on both sides of the connecting plate.

[0009] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) The present invention provides a receiving tray below the weld joint of the pipe. The baffle on the receiving tray is close to the pipe so that the sparks generated by welding can fall on the receiving tray, effectively preventing the sparks from falling to the ground and reducing the possibility of fire. At the same time, the receiving tray can also receive other falling objects such as welding rods, welding wires, and flux generated during the welding process, which greatly improves safety. The receiving tray can also hold welding tools, which greatly improves convenience. (2) The receiving tray of this utility model is provided with a folded edge, so that the receiving tray forms a box structure to prevent foreign objects from rolling down from all sides; (3) The height of the baffle of this utility model is greater than the folded edge of the receiving tray. On the one hand, it can form a surrounding edge on all four sides of the receiving tray, and on the other hand, it can extend the contact length with the pipe and increase the firmness of the receiving tray. (4) One clamp of this utility model is fixed to the pipe, and the other clamp is fastened to the pipe to improve the firmness of the fixation and prevent the fixed position from shifting.

[0010] In summary, this invention can prevent foreign objects such as sparks from falling, greatly improving safety. Attached Figure Description

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0015] The embodiment is a device for preventing sparks and foreign objects from falling during high-altitude pipe welding. like Figure 1 As shown, this embodiment includes a receiving tray 1. Both ends of the receiving tray 1 are fixed to the pipe 7 by clamps 5. The receiving tray 1 is set perpendicular to the length direction of the pipe 7. During the welding process, foreign objects such as sparks, welding rods, welding wires and flux coatings fall onto the receiving tray 1 and will not fall to the ground, greatly improving safety.

[0016] like Figure 2 As shown, the receiving tray 1 is a long, flat sheet with one long side and two short sides folded upwards to form folded edges 2 of 20mm, 25mm, or 30mm. In this embodiment, the folded edge 2 is 20mm. Multiple arc-shaped notches are provided on the other long side of the receiving tray 1, with the notches evenly spaced and their positions corresponding to the positions of the pipe rows. A baffle 3 is fixed to the side of the receiving tray 1 with the notches. The pipe rows referred to in this embodiment are multiple pipes 7 arranged side-by-side with even spacing.

[0017] like Figure 3 As shown, the baffle 3 is elongated, with multiple inwardly recessed arc-shaped grooves 4 spaced apart on it. The arc-shaped grooves 4 are recessed inwards from the surface of the baffle 3. The spacing of the arc-shaped grooves 4 matches the spacing of the pipes 7, and the curvature of the arc-shaped grooves 4 matches the diameter of the pipes 7. When the baffle 3 is connected to the receiving tray 1, the arc-shaped grooves 4 on the baffle 3 are positioned at the notch on the receiving tray 1 and welded in place. The upper edge of the baffle 3 is aligned with the upper edge of the folded edge 2 of the receiving tray 1. The height of the baffle 3 is 80mm, 90mm, or 100mm; in this embodiment, 80mm is used. Both ends of the baffle 3 protrude from both ends of the receiving tray 1, and the protruding parts of the baffle 3 are straight surfaces. Through holes are provided at the protruding parts at both ends. During installation, the arc-shaped groove 4 on the baffle 3 is fastened to the pipe bank and closely attached to the pipe 7. This prevents sparks and foreign objects from falling through the gap between the receiving tray 1 and the pipe 7, and also increases the contact length between the baffle 3 and the pipe 7, thereby improving the stability of the receiving tray 1.

[0018] The clamp 5 includes two clamps 52 and a connecting plate 51. The two clamps 52 have the same structure, and their cross-sections are arc-shaped grooves 4 that match the diameter of the pipe 7, so that they can be fastened to the pipe 7. The two clamps 52 are respectively fixed at both ends of the connecting plate 51. The height of the clamp 5 is 80mm. The connecting plate 51 is provided with through holes. When connecting, the bolts 6 pass through the baffle 3 and the through holes on the connecting plate 51.

[0019] In this embodiment, the receiving tray 1 is placed on one side of the pipe array, so that the arc-shaped groove 4 of the baffle 3 engages with the pipe 7 and is tightly attached to the pipe 7. Two clamps 5 are placed on the other side of the pipe array, located at both ends of the receiving tray 1. Taking one clamp 5 as an example, its installation method is explained: one clamp 52 on the clamp 5 engages with the outermost pipe 7 connected to the baffle 3, and the other clamp 52 engages with the adjacent pipe 7. That is, the arc-shaped groove 4 at the end of the baffle 3 and the arc-shaped groove 4 of one of the clamps 52 engage with the same pipe 7. Bolts 6 are passed through the through holes in the connecting plate 51 and the baffle 3, so that the arc-shaped groove 4 on the baffle 3 and the arc-shaped groove 4 on the connecting plate 51 clamp the pipe 7, thus fixing the receiving tray 1. After the receiving tray 1 is firmly fixed, welding is performed on this section. After welding the pipe 7 corresponding to the receiving tray 1, the device of this embodiment is moved to continue welding until all pipes 7 are welded.

[0020] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
