Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a kind of fire receiving device for welding with retractable. BACKGROUND

[0002] In the process of rapid development of today's society, the construction industry is thriving, various buildings are emerging, and the construction form is more and more complex and diverse, and the construction difficulty is increasing, which puts forward higher requirements for construction personnel. As a common structure form in building engineering, welding operation is an essential part in the construction process of steel structure. Especially in high-altitude welding operation, how to properly handle the falling welding slag during welding has become a recurring problem faced by on-site fire management. Because the welding operation point is in the air, if the falling welding slag cannot be effectively received, it is easy to cause a fire accident, which seriously threatens the safety of personnel and property on the construction site, therefore, to ensure the fire receiving effect and fire safety during steel structure welding operation has become the top priority in construction management, which makes the development of an efficient and practical umbrella-shaped retractable fire receiving basin device a key.

[0003] In the actual operation of building construction, the ordinary fire receiving basin exposes many problems. On the one hand, its size is usually small and the depth is shallow, and this design limitation makes it impossible to ensure that all the welding slag sparks falling during welding can be received, and the welding slag may fall from the edge or gap of the fire receiving basin, which is easy to cause fire hazards, and once the welding slag contacts flammable materials, it may cause a fire accident, which brings immeasurable losses to the construction site, on the other hand, the structure of the ordinary fire receiving basin is relatively fixed and cannot be flexibly applied to high-altitude welding operation scene. The high-altitude operation environment is complex and variable, and the fire receiving basin needs to be adjusted according to the actual situation, but the ordinary fire receiving basin cannot be retracted and extended freely, and cannot well adapt to the needs of different operation positions and working conditions. In addition, when welding is performed above the complex environment with flammable materials, the ordinary fire receiving basin has unsatisfactory fire receiving effect, in order to prevent fire, the construction party has to increase labor input to monitor the possible fire at all times, and also needs to be equipped with more fire fighting equipment, and even build a protective shed, which undoubtedly greatly increases the construction cost, reduces the construction efficiency, and has a negative impact on the whole project progress and economic benefit.

[0004] A fire receiving device disclosed in patent No. 201510375207.1 adopts a retractable umbrella-shaped fire receiving hopper design, including a supporting rod, an umbrella-shaped framework, an umbrella cloth, a fastening mechanism and an adjusting rod. The umbrella cloth is coated with a layer of flame-retardant material.

[0005] This design improves the fire-catching effect to some extent, but it still has some shortcomings. The umbrella-shaped structure is easily affected by wind at high altitudes, and the connection between the adjusting rod and the support rod may loosen or deform, affecting the position and stability of the fire-catching bucket and reducing the fire-catching effect. Moreover, the umbrella fabric is not durable enough under the impact of high-temperature welding slag for a long time and is easily damaged, affecting its service life and fire resistance. Although the fire-catching umbrella surface is coated with a flame-retardant material layer and laid with a high-temperature resistant material layer (such as a glass wool layer), the durability of the umbrella fabric and related materials may be insufficient under the impact of high-temperature welding slag for a long time, and they are prone to damage, affecting their service life and fire resistance.

[0006] In conclusion, there is still a need for a durable, umbrella-shaped, retractable fire-receiving basin device that is structurally stable, provides good fire-receiving performance, can adapt to complex high-altitude environments, and is durable. This device would effectively solve the problem of receiving welding slag during high-altitude welding operations of steel structures, ensuring construction safety and efficiency. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a retractable welding slag receiving device that effectively solves the problem of slag reception in high-altitude welding operations of steel structures, ensuring construction safety and efficiency.

[0008] To solve the above problems, the technical solution adopted by this utility model is: a retractable welding fire-receiving device, including a fixed rod, on which an adjustable sliding locking ring is provided, which is slidably connected to the fixed rod; a locking device is provided at one end of the fixed rod, and a collection box is provided at the other end, which is fixedly connected to the fixed rod; a plurality of frames are provided at one end of the collection box, which are movably connected to the fixed rod through the fixed ring; the frames and the adjustable sliding locking ring are movably connected through a support frame; and a fireproof cloth is fixedly provided on the frames.

[0009] The principle of this solution is as follows: During high-altitude welding of steel structures, the fixed rod serves as the supporting structure of the entire device, maintaining stability. The adjustable sliding locking ring can slide on the fixed rod, changing the position of the support frame connected to the skeleton by sliding, thereby enabling the fire basin to be unfolded and retracted. When the fire basin needs to be unfolded for use, the adjustable sliding locking ring is slid to the appropriate position to fix it, allowing the support frame to support the skeleton and form an umbrella-shaped structure. The fireproof cloth fixed on the skeleton can effectively block the welding slag and sparks falling during the welding process. The welding slag produced by welding first falls on the fireproof cloth, and then slides down the skeleton into the collection box. The collection box is fixedly connected to the fixed rod to ensure that the welding slag can be stably caught, preventing the welding slag from falling and causing safety hazards.

[0010] The beneficial effects of this plan are:

[0011] 1. The sliding connection between the movable ring and the fixed rod allows the fire-catching basin to be flexibly adjusted to the degree of unfolding according to actual operation needs, thereby maximizing the catching of welding slag and avoiding the safety hazards caused by welding slag splashing everywhere.

[0012] 2. The locking device at one end of the fixed rod ensures that the movable ring can be stably fixed after being adjusted to the appropriate position. This is especially important in high-altitude working environments, preventing the position of the fire-catching basin from changing due to shaking or wind, thus ensuring the stability and reliability of the fire-catching. The collection box can collect the falling welding slag, preventing it from scattering on the construction site and reducing the difficulty and cost of subsequent cleanup. At the same time, the fixed connection between the collection box and the fixed rod ensures its firmness during the slag-catching process and prevents it from falling off. The movable connection between the frame and the fixed rod through the fixed ring and the movable connection with the movable ring through the support frame gives the entire fire-catching basin device good adaptability and flexibility. It can freely adjust its angle and shape in complex high-altitude working environments to better catch welding slag.

[0013] Furthermore, the locking device is fixedly connected at both ends by bolts. The bolt connection provides strong fastening force, ensuring that the locking device will not easily loosen when fixing the movable ring, thus guaranteeing the stability and reliability of the fire basin during use. In high-altitude operations, various external forces may affect the device, and the bolt connection can withstand significant loads and vibrations, ensuring that the performance of the locking device remains unaffected.

[0014] Furthermore, the frame consists of multiple members arranged in a ring around the fixing rod. The frame is hinged to the fixing rod via a fixing ring. This arrangement of multiple frames around the fixing rod ensures more even stress distribution on the fire-receiving basin when receiving welding slag, preventing excessive localized stress that could lead to structural deformation or damage. Simultaneously, it provides comprehensive and stable support for the fireproof cloth, ensuring it can effectively unfold and catch the welding slag, preventing localized depressions or sagging.

[0015] Furthermore, the support frame, adjustable sliding locking ring, and skeleton are all hinged. The hinged design allows the support frame to rotate freely within a certain range, thereby flexibly adjusting the angle between the skeleton and the adjustable sliding locking ring to adapt to different operating scenarios and fire connection requirements.

[0016] Furthermore, the frame is equipped with multiple fixing buckles, which are fixed to the frame by locking bolts. Each fixing buckle is also equipped with a connector, which connects to the fixing buckle through a connector. The multiple fixing buckles are fixed to the frame by locking bolts, which can more firmly fix the fireproof cloth or other related components and prevent them from loosening or falling off due to force during fire contact. At the same time, when a fixing buckle or connector is damaged, it can be replaced individually by loosening the locking bolts without replacing the entire frame, thus reducing maintenance costs and difficulty.

[0017] Furthermore, the connector is provided with a connecting strap, which is fixedly connected to the fireproof cloth. The connecting strap makes the connection between the fireproof cloth and the connector more stable, preventing the fireproof cloth from separating from the frame or shifting due to external force during the fire exposure process, and ensuring that the fireproof cloth is always in an effective protective position. When the fireproof cloth needs to be replaced due to long-term use or damage, the separation of the connecting strap from the connector makes it easier to disassemble and install the fireproof cloth.

[0018] Furthermore, the connecting strap is a Velcro strap, which is easy to use and can quickly adhere and separate, greatly improving the efficiency of installing and replacing fireproof cloth. It can provide strong adhesion to ensure a tight connection between the fireproof cloth and the connecting parts, making it difficult to loosen.

[0019] Furthermore, the fireproof cloth extends into the collection box from the end closest to it, which effectively prevents welding slag from falling from the connection between the fireproof cloth and the collection box, ensuring that all welding slag can be collected into the collection box. This reduces the possibility of welding slag leakage causing safety hazards and environmental pollution. The fireproof cloth extending into the collection box can guide the welding slag to fall into the collection box more accurately, improving the efficiency and integrity of the collection.

[0020] Furthermore, each of the connecting fasteners is provided with a corresponding connecting hole, which is fixedly connected by a bolt. The bolt provides a strong and reliable tightening force, ensuring that the connection between the connecting component and the fastener is firm and not easy to loosen, and remains stable when subjected to external forces and vibrations.

[0025] Example 1 is basically as shown in the appendix. Figs. 1-3As shown: A retractable welding ignition device includes a fixed rod 1, which serves as the main support structure of the entire device, ensuring stability during use. An adjustable sliding locking ring 2 is mounted on the fixed rod 1, which is slidably connected to the fixed rod 1. The operator can easily slide the adjustable sliding locking ring 2 onto the fixed rod 1 to a suitable position according to actual work requirements. Once the position is determined, the adjustable sliding locking ring 2 is locked to fix its open size. Then, a locking device 7 is used at one end of the fixed rod 1 to fix the fixed rod 1. The locking device 7 is fixed at both ends by bolts. The direction and position of the fixed rod 1 can be flexibly changed according to actual needs to adapt to different working scenarios and installation requirements.

[0026] A collection box 6 is fixedly connected to the other end of the fixed rod 1 to catch the falling welding slag. One end of the collection box 6 is provided with multiple skeletons 3. These skeletons 3 are distributed in a ring around the fixed rod 1 and are hinged to the fixed rod 1 through a fixed ring. This ring distribution makes the fire basin more evenly stressed when receiving welding slag, avoiding excessive local stress that could lead to structural deformation or damage. At the same time, the hinge of the fixed ring provides the skeleton 3 with the possibility of flexible rotation, which can adjust the angle and shape according to different working scenarios and fire-catching requirements.

[0027] The frame 3 and the adjustable sliding locking ring 2 are movably connected through the support frame 4. The support frame 4, the adjustable sliding locking ring 2, and the frame 3 are all hinged. This hinged connection allows the support frame 4 to rotate freely at a certain angle, further increasing the flexibility of the fire basin angle adjustment and adapting to more diverse working environments.

[0028] The frame 3 is equipped with multiple fixing buckles 8, which are fixed to the frame 3 by locking bolts 10. The fixing buckles 8 are equipped with connectors 12, which are connected to the fixing buckles 8 through the connectors 14. This allows the fixing buckles 8 to more firmly fix the fireproof cloth 5 or other related components, preventing them from loosening or falling off due to force during fire contact. Moreover, when the fixing buckles 8 or connectors 12 are damaged, they can be replaced individually by simply loosening the locking bolts 10, reducing maintenance costs and difficulty.

[0029] The connector 12 is equipped with a Velcro-style connecting strap, which is used to securely connect the fireproof cloth 5. The Velcro is easy to use, allowing for quick adhesion and separation, greatly improving the efficiency of installing and replacing the fireproof cloth 5. At the same time, its strong adhesion ensures a tight connection between the fireproof cloth 5 and the connector 12, preventing it from easily coming loose.

[0030] The fireproof cloth 5 extends into the collection box 6 from one end, effectively preventing welding slag from falling from the connection between the fireproof cloth 5 and the collection box 6. This ensures that all welding slag can be collected into the collection box 6, reducing the possibility of safety hazards and environmental pollution. At the same time, the fireproof cloth 5 extending into the collection box 6 can guide the welding slag to fall into the collection box 6 more accurately, improving the efficiency and integrity of collection.

[0031] In actual use, the fire basin device is fixed in a suitable position by the mounting structure at the top of the fixing rod 1. The adjustable sliding locking ring 2 is slid to unfold the frame 3, forming an umbrella-shaped structure. Then, the locking device 7 is used to fix it. When performing high-altitude welding operations on steel structures, the welding slag produced by welding falls onto the fireproof cloth 5 and slides down the frame 3 into the collection box 6 for centralized collection. After the operation is completed, the locking device 7 is released and the frame 3 is retracted for easy storage and transportation.
