Description

A protective device for welded points of steel tie rods Technical Field

[0001] This utility model relates to the technical field of welding point protection devices, specifically a welding point protection device for steel tie rods. Background Technology

[0002] The steel tie rod welding point protection device is a protective shell installed at the welding point of the steel tie rod by fixing a clamp, and an observation window is opened on the surface of the protective shell. The spatter and sparks generated during the welding process are blocked by the protective shell and will not splash into the surrounding environment, thus avoiding injury to personnel and equipment.

[0003] Existing protective devices for steel tie rod welding points require wrapping the welding points to prevent weld slag from harming welders during welding. This wrapping blocks the weld slag, arc light, and radiation generated during welding, allowing welders to perform welding operations more effectively. However, this method results in the accumulation of a lot of smoke during welding, which not only affects the welding process but also causes harm to workers due to the toxic fumes.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a protective device for the welding points of steel tie rods. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device for the welding points of steel tie rods to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for welding points of steel tie rods, comprising a protective device body, a welding port on the front surface of the protective device body, an observation window on the upper surface of the protective device body, lifting plates on both upper surfaces of the protective device body, multiple ventilation openings on the rear and side surfaces of the protective device body, threaded joints on the outer surface of the ventilation openings, connecting sleeves spirally installed on the outer surface of the threaded joints, exhaust fans on the end surface of the connecting sleeves, and filter screens on the end surface of the exhaust fans.

[0007] Preferably, a connecting ring is slidably installed on the inner surface of the exhaust fan, and a particle filter plate is provided on the inner surface of the connecting ring.

[0008] Preferably, the lower surfaces of both sides of the main body of the protective device are provided with slots, and the two sides of the slots are provided with connecting plates.

[0009] Preferably, a limiting slide rod is slidably installed through the surface of the connecting plate, and a compression spring is provided on the outer surface of the limiting slide rod.

[0010] Preferably, the end surface of the limiting slide bar is provided with a clamping plate, and the upper surface of the clamping plate is provided with a pull block.

[0011] Preferably, the inner surface of the clamp is provided with an anti-slip sleeve, and the anti-slip sleeve is made of rubber material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the arrangement of a protective device body, welding joint, observation window, lifting plate, threaded joint, ventilation opening, connecting sleeve, exhaust fan, filter screen, connecting retaining ring, and particle filter plate, achieves multi-directional airflow by installing multiple exhaust fans on the rear and side surfaces of the protective device body. This prevents welding fumes from accumulating locally under the action of the airflow, thereby accelerating their diffusion and discharge. The multi-angle airflow also disrupts the flow path of the fumes, preventing fumes from flowing in a single direction and causing poor fumes extraction in some areas. The particle filter plate filters welding slag particles from the fumes, preventing welding personnel from inhaling these particles and causing injury.

[0014] 2. This utility model, through the setting of a bayonet, connecting plate, limiting slide bar, compression spring, clamping plate, anti-slip sleeve and pull block, and the setting of compression spring, can quickly clamp and fix the main body of the protective device at the position to be welded by resetting the clamping plate, thereby improving the welding effect of the steel tie rod. At the same time, after the welding contact, the clamping plate can be quickly opened by pulling the pull block, so that the main body of the protective device can be removed from above the welding point.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1-3, a protective device for steel tie rod welding points includes a protective device body 1. The front surface of the protective device body 1 has a welding port 101, and the upper surface of the protective device body 1 is provided with an observation window 102. Furthermore, the upper surfaces of both sides of the protective device body 1 are provided with lifting plates 103. The advantage of this arrangement is that, through the observation window 102, the welding condition of the steel tie rod can be observed during welding through the welding port 101.

[0022] Furthermore, the rear and side surfaces of the protective device body 1 are provided with multiple ventilation openings 201, and the outer surface of the ventilation openings 201 is provided with threaded joints 2. The advantage of this setting is that the ventilation openings 201 can help the exhaust fan 203 to discharge the smoke generated during welding, and avoid the smoke accumulation affecting the normal welding.

[0023] Furthermore, a connecting sleeve 202 is spirally installed on the outer surface of the threaded joint 2, and an exhaust fan 203 is provided on the end surface of the connecting sleeve 202, and a filter screen 204 is provided on the end surface of the exhaust fan 203. The advantage of this arrangement is that by installing multiple exhaust fans 203 on the rear and side surfaces of the protective device body 1, multi-directional airflow can be formed, preventing the welding fumes from accumulating locally under the action of the airflow, thereby accelerating their diffusion and discharge speed. The multi-angle airflow can also disrupt the flow path of the fumes, avoiding the situation where the fumes flow in a single direction, resulting in poor fumes extraction in some areas.

[0024] Furthermore, a connecting ring 205 is slidably installed on the inner surface of the exhaust fan 203, and a particle filter plate 206 is provided on the inner surface of the connecting ring 205. The advantage of this setting is that the particle filter plate 206 can filter welding slag particles in the smoke, preventing welding slag particles from being inhaled by the welder and causing injury to the welder.

[0025] As shown in Figure 4, the lower surfaces of both sides of the protective device body 1 are provided with slots 3, and the two sides of the slots 3 are provided with connecting plates 301. The advantage of this setting is that the protective device body 1 can be easily installed at the position where welding is required, so that it fits with the connection point.

[0026] Furthermore, a limiting slide rod 302 is slidably installed through the surface of the connecting plate 301, and a compression spring 303 is provided on the outer surface of the limiting slide rod 302. A clamping plate 304 is provided on the end surface of the limiting slide rod 302, and a pull block 306 is provided on the upper surface of the clamping plate 304. By setting the compression spring 303, the clamping plate 304 can be quickly clamped and fixed at the position to be welded by resetting, thereby improving the welding effect of the steel tie rod. At the same time, after the welding contact, the clamping plate 304 can be quickly opened by pulling the pull block 306, so that the protective device body 1 can be removed from above the welding point.

[0027] Furthermore, the inner surface of the clamping plate 304 is provided with an anti-slip sleeve 305, which is made of rubber material. The advantage of this setting is that, by setting the anti-slip sleeve 305, the friction between the clamping plate 304 and the connection point can be increased after the clamping plate 304 is attached to the connection point, so as to avoid the protective device body 1 from loosening during the welding process and affecting the normal welding effect.

[0028] Working principle: When using this steel tie rod welding point protection device, firstly, when welding the steel tie rod, in order to ensure the installation of the weld, the main body 1 of the protection device with the bayonet 3 can be aligned with the position to be welded, and then the pull block 306 is pulled to drive the clamping plate 304 to pull backward to open the bayonet 3. After the main body 1 of the protection device is installed at the position of the welding point, the pull block 306 is released and its compression spring 303 will drive the limit slide rod 302 to retract inward through the reset characteristic. At the same time, the clamping plate 304 fits with the connection point to complete the fixation of the main body 1 of the protection device. After the steel tie rod is fixed and welded through the welding joint 101, the welding process can be observed through the observation window 102. To reduce the interference of smoke on the welding, multiple exhaust fans 203 installed on the outer surface of the protective device body 1 can be activated to remove smoke from the inside of the protective device body 1. The smoke contains toxic welding slag particles, which are also filtered by the particle filter plate 206 to reduce the interference of smoke on the welders. When maintenance is required on the exhaust fan 203, simply unscrew the exhaust fan 203 with the connecting sleeve 202 along the threaded joint 2 to maintain the exhaust fan 203 and the particle filter plate 206 installed inside the exhaust fan 203. This is the working principle of the steel tie rod welding point protection device.
