Description

Technical Field

[0001] This invention belongs to the field of welding safety protection technology, specifically relating to an adjustable welding slag collection device. Background Technology

[0002] In the renovation project of the substation integrated automation system, the construction of new panels and cabinets and supporting cable channels in the protection room is a routine operation. However, the hot work and cutting procedures involved pose significant safety hazards. Since the cable layer usually contains a large number of live cables, its fire protection requirements are extremely strict. In traditional construction, even if temporary protective measures such as double fixed-size metal trays and fire blankets are set up on the upper and lower floors of the work point, it is still difficult to effectively control the problem of welding slag scattering caused by the difference in building height. High-temperature sparks frequently fall onto cable trays or electrical equipment, which may not only cause electrical short circuit accidents, but also pose a risk of causing major fires, seriously threatening the safe operation of the power system.

[0003] Existing protective technologies mainly rely on fixed metal trays and temporary fire blankets. Fixed metal trays have drawbacks such as limited adjustment range, low slag cooling efficiency, and secondary splashing caused by hard impacts. Temporary fire blankets require frequent repositioning, resulting in poor sealing, time-consuming installation, and high wear and tear from repeated use. For special scenarios such as substations, existing technologies cannot simultaneously meet the core requirements of dynamic adjustment, rapid cooling, splash-proof sealing, and low-cost maintenance. Therefore, there is an urgent need for an innovative protective device that can efficiently collect and isolate welding slag in complex construction environments, fundamentally improving the safety and economy of hot work operations. Utility Model Content

[0004] To address the problems of inconvenient adjustment, low cooling efficiency, and poor anti-splatter performance of existing hole welding protection devices, this paper proposes a welding slag collection device based on mechanical positioning adjustment and a yellow sand buffer layer, hereinafter referred to as an adjustable welding slag collection device.

[0005] The core structure of the adjustable welding slag collection device consists of two main parts: the welding slag collection device and the support assembly. The welding slag collection device includes a welding slag collection bucket and a fixed support. The support assembly includes a movable support, bolts, and a fixing pin. Both the fixed support and the movable support are provided with bolt connection holes. The movable support is connected to the fixed support through the bolt connection holes, and the fixing pin is connected to the movable support through the bolt connection holes. The two ends of the fixing pin are connected to the wall panel at the welding point. The fixed support is a rectangular support with a row of equally spaced bolt connection holes in the middle of the horizontal direction. The movable support consists of two bent angle irons with a row of bolt connection holes corresponding to the fixed support in the middle of the vertical direction. The lower end of the movable support is connected to the fixed support through the bolt connection holes, and the upper end passes through the through hole in the wall panel. The fixing pin is a cylinder with a diameter smaller than the bolt connection hole and is connected to the bolt connection hole of the movable support that passes vertically through the wall panel.

[0006] The bottom of the slag collection bucket is filled with 30-50mm of dry yellow sand, which can quickly absorb the heat of the slag. The dense structure of the sand layer effectively isolates the air and prevents the slag from reigniting. The displacement between sand particles consumes the impact energy and suppresses secondary splashing.

[0007] The fixed bracket is a high-strength rectangular bracket, and its axial ends are welded and fixed to the inner wall of the welding slag collection bucket.

[0008] The movable support consists of two bent angle irons. The lower ends of the two movable supports are connected to the fixed support by bolts, allowing for quick positioning and height adjustment according to usage requirements.

[0009] Both the movable and fixed supports are equipped with equidistant bolt connection holes to achieve multi-level adjustment. The vertical adjustment range of the movable support is 10-50mm, and the horizontal adjustment range is 5-25mm.

[0010] The fixed pin and movable bracket are detachably connected, and the height can be quickly adjusted according to the usage. The fixed pin can be used with round and irregular bolt connection holes with a diameter of 10mm, which has excellent adaptability to working conditions and can meet a variety of installation requirements.

[0011] The lower end of the movable bracket is connected to the fixed bracket through bolt holes, and the upper end passes through a perforation in the wall panel. The wall panel has welding perforations, and two movable brackets are installed through the perforations to enhance the stability of the device. The fixed pins are two cylindrical structures with a diameter smaller than the diameter of the bolt holes to ensure flexible insertion and removal. The fixed pins and the bolt holes of the movable brackets that pass through the wall panel form a detachable connection for easy adjustment and fixation.

[0012] During installation, the upper end of the movable bracket passes through the wall panel and is positioned using a fixing pin. The two ends of the fixing pin are placed on the platform outside the hole in the wall panel to form a simply supported beam structure.

[0013] During welding operations, the high-temperature welding slag falls freely into the welding slag collection device without damaging the protective equipment. When the welding slag collection bucket reaches its rated capacity, it needs to be cleaned. The disassembly process is as follows: first, pull out the fixing pin to release the movable bracket, then remove the entire welding slag collection device, and finally pour the mixture of yellow sand and welding slag into a special recycling container. The welding slag and yellow sand are separated by a screen to replenish the lost sand. After drying, the yellow sand can be reused.

[0014] Beneficial effects:

[0015] The adjustable welding slag collection device adopts a modular design, mainly composed of two parts: the welding slag collection device and the support assembly. It features quick installation, multi-level adjustment, and safety protection. Through the innovative design of the adjustable support assembly and the yellow sand buffer layer, the device comprehensively solves the pain points of traditional welding protection operations, such as cumbersome adjustment, insufficient cooling, and poor spatter control. It also has the advantages of high efficiency, safety, environmental protection, and recyclability, and is particularly suitable for high-frequency and high-risk welding operation environments.
