Description

Technical Field

[0001] This utility model relates to an auxiliary smoke exhaust device, specifically an auxiliary smoke exhaust device for an electromechanical welding workbench, belonging to the field of construction safety protection technology. Background Technology

[0002] Generally, electromechanical installation projects often involve a large amount of welding work, especially in material processing areas. Traditional welding methods primarily involve placing materials in the processing area and performing manual welding. Due to the limitations of the processing site environment and the lack of corresponding fume extraction equipment, welding fumes accumulate in the processing area due to poor ventilation, affecting processing efficiency, causing localized environmental pollution, and hindering the management of civilized construction practices. Furthermore, the lack of appropriate fume extraction devices in welding operations presents the following technical defects and shortcomings:

[0003] On the one hand, the welding process generates a large amount of fumes containing heavy metals such as manganese, chromium, and cadmium, as well as harmful gases such as ozone and nitrogen oxides. Short-term exposure can cause discomfort such as dizziness, nausea, and coughing, affecting judgment and concentration during work. Long-term exposure can lead to "welder's pneumoconiosis," an irreversible occupational disease that may also induce respiratory diseases such as asthma and bronchitis.

[0004] On the other hand, it increases on-site safety hazards. The accumulation of welding fumes and harmful gases will indirectly increase on-site safety risks. Some welding gases (such as gases produced by the incomplete combustion of acetylene) are flammable. When the concentration reaches a certain level, they may cause an explosion when exposed to open flames or high temperatures. High concentrations of fumes will obstruct the vision of workers, which may lead to welding operation errors and cause accidents such as electric shock, fire or equipment collision.

[0005] On the other hand, fumes adhering to the welding area or equipment surface can affect the quality of the weld joint, potentially leading to problems such as incomplete welding or slag inclusion, thus reducing the service life and safety of the electromechanical equipment. Untreated fumes spreading to the surrounding area can pollute the building's internal environment, requiring additional manpower and costs for subsequent cleanup, which is often very inconvenient.

[0006] Therefore, the key to solving the above-mentioned technical problems lies in developing a safe, reliable, and practical auxiliary fume extraction device for electromechanical welding operations. Summary of the Invention

[0007] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, with the aim of providing a simple structure and novel and reasonable design that can greatly improve the fume extraction efficiency during welding operations, reduce the concentrated distribution of toxic and harmful gases to a certain extent, effectively reduce the occupational health hazards of construction operators, and assist in the high-quality and efficient completion of welding operations.

[0008] To solve the above problems and achieve the above-mentioned objectives, this utility model provides an auxiliary fume extraction device for electromechanical welding operations, which is achieved by adopting the following design structure and the following technical solution:

[0009] An auxiliary fume extraction device for electromechanical welding operations includes:

[0010] A mobile welding operation platform is connected to the bottom of the support frame;

[0011] The canopy is set above the mobile welding operation platform, and there are mounting holes running through both sides of the canopy.

[0012] Smoke exhaust fan, which is detachably installed on the mounting hole;

[0013] A pre-installed duct is provided above the exhaust fan for connection to the exhaust duct of the temporary ventilation and smoke exhaust system.

[0014] The sensor is installed at the bottom of the ceiling and is electrically connected to the exhaust fan via a wire to control the start and stop of the exhaust fan.

[0015] Preferably, the mobile welding operation platform includes:

[0016] The front support legs are arranged opposite to each other.

[0017] The rear support legs are arranged opposite to each other.

[0018] The top frame bracket surrounds the top of the two front support legs and the two rear support legs.

[0019] The welding workbench is connected at its four corners to the lower inner walls of two front support legs and two rear support legs, respectively.

[0020] The moving device is installed at the bottom of the lower ends of the two front support legs and the two rear support legs respectively;

[0021] Enclosed baffles are installed at the rear ends or sides of the two front support legs and the two rear support legs, respectively.

[0022] Preferably, the front support leg is a bent support leg made of multiple sections of angle steel, channel steel, or C-shaped steel assembled and welded together;

[0023] The rear support leg is a vertical section of support leg made of angle steel, channel steel, or C-shaped steel.

[0024] The top frame support is made of four angle steel, channel steel or C-shaped steel of different lengths.

[0025] Preferably, the welding workbench is an integral "concave" plate-shaped component;

[0026] The moving device is a directional wheel or a swivel wheel, and a brake device that matches it is provided on the directional wheel or swivel wheel.

[0027] Preferably, the canopy is a square plate-shaped component, which is detachably mounted on the top of the mobile welding operation platform;

[0028] Symmetrical ring handles are provided on one or both sides of the ceiling.

[0029] Preferably, the enclosed baffle is a combination of square plate-shaped and irregular plate-shaped components.

[0030] Preferably, the mobile welding operation platform further includes:

[0031] The reinforcing ribs are made of angle steel, channel steel, or C-shaped steel, and are connected to the rear ends of the two front support legs and the sides of the two rear support legs.

[0032] Preferably, the exhaust fan is an exhaust fan or a ventilation fan; the reserved air duct is a reserved PVC air duct.

[0033] Preferably, the sensor is a smoke detector.

[0034] Preferably, the mobile welding operation platform, the canopy, the exhaust fan, the reserved air duct, and the outer surface of the exhaust pipe are all provided with an injection molding layer, an anti-rust layer, a waterproof layer, and a warning layer in sequence from the inside to the outside, and the warning layer is coated with fluorescent powder.

[0035] The working principle is as follows: Before using the above-mentioned auxiliary smoke exhaust device for electromechanical welding operations, the completed device needs to be transported to the designated construction location by manual labor or appropriate handling equipment for installation as a backup.

[0036] When in use, firstly, based on the actual site conditions, manufacture or purchase finished C-shaped steel combination and assemble the new type of smoke exhaust auxiliary device. Then, arrange the auxiliary smoke exhaust device for electromechanical welding operations in the material processing area. When welding operations are required, the processing operations are carried out directly on the welding operation table (14) of the mobile welding operation platform (1). For example, the operator directly takes the pre-prepared welding machine (7) and the pipe hanger (8) to be welded to the welding operation table (14) and places them there. Then the welding operation can be carried out. When welding, just align the welding machine (7) with the pipe hanger (8) to be welded. During the welding process, when the welding machine (7) generates smoke, the smoke exhaust fan (3) is activated through the sensor (5) to discharge the smoke (9) generated by welding through the exhaust pipe (6) of the temporary exhaust system to the processing area, thereby quickly discharging toxic and harmful gases and effectively assisting the welding construction efficiency.

[0037] Finally, as time goes by, when all the pipe hangers (8) or other small parts of the building that need to be welded are completed and the present invention is no longer needed, the operator only needs to pull the exhaust pipe (6) of the present invention out of the reserved air pipe (4) to separate it from the present invention. Then, after cleaning and repairing each part of the present invention, it can be transported to the designated tool storage warehouse for storage by the corresponding handling equipment or by manual labor for the next cycle of use.

[0038] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0039] 1. The self-made auxiliary fume extraction device for electromechanical welding operations of this utility model can greatly improve the fume extraction efficiency during welding operations, reduce the concentrated distribution of toxic and harmful gases to a certain extent, effectively reduce the occupational health hazards of construction operators, and assist welding operations to be completed with high quality and efficiency.

[0040] 2. This utility model is simple to manufacture, not easily damaged, detachable, reusable, and easy to carry. It effectively reduces the toxic and harmful gases in the welding area and effectively assists in welding construction efficiency. At the same time, the rapid emission of harmful gases also reduces occupational health hazards to construction operators. The integrated welding platform also enables centralized management of welding operations in the material processing area, strengthens the management of on-site civilized construction, and has a positive significance for promoting green and energy-saving construction in installation projects.

[0041] 3. This utility model uses a ventilation fan to not only remove local smoke and dust, but also promote air circulation in the work area and improve overall comfort; while removing welding smoke and harmful gases, it can introduce fresh air, reduce the concentration of harmful gases in the work area, reduce the stuffiness of personnel, and the air flow of the ventilation fan can remove some heat, indirectly alleviating the high temperature discomfort of the workers.

[0042] 4. This utility model solves the problem that welding fumes are generated quickly and have large concentration fluctuations. The smoke detector can capture concentration changes in real time, avoiding delays and omissions in manual inspections. The smoke detector can be directly linked with exhaust devices, such as ventilation fans and exhaust pipes, to achieve "automatic exhaust when fumes exceed the standard", reducing reliance on manual operation.

[0043] 5. The exterior of this utility model is coated with an anti-rust layer and a waterproof layer, which can prevent rusting and extend the service life of the entire smoke exhaust device, achieving environmental protection and saving resources. At the same time, the exterior of the smoke exhaust device is coated with a self-illuminating fluorescent material, which can clearly mark the location of the smoke exhaust device at night or in dark indoor and underground construction environments, effectively playing a safety warning role, improving visibility, making it easy for people to identify, and increasing safety in construction and daily life.
