Description

Technical Field

[0001] This utility model relates to the field of welding technology for building steel structures, specifically a windproof device for welding building steel structures. Background Technology

[0002] During the fabrication of steel structures, welding machines are required for on-site welding. Environmental parameters for welding include humidity, temperature, and wind speed. Wind speed directly affects the welding quality. To ensure welding quality, wind protection measures are usually taken at the welding site.

[0003] Currently, when carrying out windproofing, materials such as canvas and plastic sheeting are usually fixed and installed using ropes and wires. This process is not only cumbersome and time-consuming, but the canvas and plastic sheeting are also easily blown or swayed in strong winds, failing to form an effective windproof barrier and reducing the windproof effect. Therefore, we propose a welded windproof device for building steel structures. Utility Model Content

[0004] The purpose of this utility model is to provide a windproof device for welded steel structures in buildings, in order to solve the problem that in the current windproof treatment, the installation process is not only cumbersome, but also that materials such as canvas and plastic sheeting are easily blown or shaken when the wind is strong, which makes it impossible to form an effective windproof barrier and reduces the windproof effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a windproof device for welded steel structures, comprising a windbreak plate, an observation window being provided through the bottom of one side of the windbreak plate, clamping mechanisms being symmetrically arranged on one side of the windbreak plate, and a ventilation adjustment mechanism being provided at the top of one side of the windbreak plate.

[0006] The clamping mechanism includes an L-shaped plate symmetrically fixed to one side of the windshield. A sliding groove is symmetrically opened on one side of the L-shaped plate, and a slider slides inside the sliding groove. A clamping plate is fixed to one side of the slider, and a force-bearing plate is fixed to one side of the clamping plate. A placement groove is opened on one side of the force-bearing plate. A first sleeve is provided on one side of the L-shaped plate. A first screw slides through the middle of one side of the first sleeve. A first knob is screwed to the outside of the first screw, and a pressure plate is fixed to one end of the first screw.

[0007] Preferably, the clamping mechanism further includes a mounting base fixed to one side of the L-shaped plate, a rotating block rotating inside the mounting base, a mounting plate fixed to one side of the rotating block, a first sleeve fixed to the middle of one side of the mounting plate, a limit groove formed on one side of the first sleeve, limit blocks symmetrically connected inside the limit groove, a second sleeve symmetrically fixed to one side of the mounting plate, and limit rods symmetrically fixed to one side of the pressure plate.

[0008] Preferably, the outer side of the first knob is provided with anti-slip texture, and the other end of the first screw is fixed with a first baffle, which is located inside the first sleeve to prevent the first screw from falling off.

[0009] Preferably, the limiting block is fixed to one side of the first knob to limit the first knob so that the first knob can only rotate. The limiting rod slides inside the second sleeve, and one end of the limiting rod is fixed with a second baffle located inside the second sleeve to prevent the limiting rod from falling off.

[0010] Preferably, the slider and the slide groove are T-shaped, a handle is fixed in the middle of one side of the pressure plate to facilitate pulling the pressure plate, and tempered glass is fixed inside the observation window.

[0011] Preferably, the ventilation adjustment mechanism includes a ventilation opening extending through the top of one side of the wind deflector, a mounting frame fixed to the top of one side of the wind deflector, rotating shafts evenly extending through both sides of the mounting frame, adjusting plates fixed to opposite sides of the two rotating shafts, a gear fixed to one end of each rotating shaft, a bearing embedded in the top center of the mounting frame, connecting rods symmetrically fixed to the top of the mounting frame, a sliding plate sliding on the outer side of the connecting rods, racks symmetrically fixed to the bottom of the sliding plate, a second screw fixed to the inner ring sidewall of the bearing, and a second knob fixed to the top of the second screw.

[0012] Preferably, the rack is meshed with the gear, and when the rack moves, it drives the gear to rotate. The movable plate is screwed to the outside of the second screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes a clamping mechanism. By attaching the L-shaped plate to the outer side of the steel structure, and then pulling the pressure plate, the first screw and the limiting rod are positioned inside the placement groove. Rotating the first knob causes the first screw to move, which in turn moves the pressure plate, causing it to press against the load-bearing plate. This, in turn, causes the clamping plate to press against the steel structure, thereby fixing the windbreak plate. This facilitates the installation of the windbreak plate, saves installation time, improves installation efficiency, and prevents the windbreak plate from being blown away by strong winds, forming an effective windproof barrier, improving wind protection, and avoiding interference with welding.

[0015] 2. In this application, the ventilation adjustment mechanism is designed to meet the ventilation requirements during the welding process. By rotating the second knob, the second screw is rotated. The connecting rod limits the movement of the moving plate outside the connecting rod, which in turn causes the rack to descend, driving the gear to deflect. This causes the rotating shaft to deflect the adjustment plate, allowing some air to enter one side of the wind baffle through the vent, ensuring airflow during the welding process. When the wind is strong, the adjustment plate can be closed to avoid the influence of the wind, making it easy to adjust as needed and improving the practicality of the device.

A force-bearing plate 340 is fixed to one side of the clamping plate 330. A placement groove 341 is provided on one side of the force-bearing plate 340. A first sleeve 370 is provided on one side of the L-shaped plate 310. A first screw 380 slides through the middle of one side of the first sleeve 370. A first knob 381 is screwed onto the outer side of the first screw 380. One end of 80 is fixed with a pressure plate 382; the clamping mechanism 300 also includes a mounting base 350 fixed to one side of the L-shaped plate 310, a rotating block 351 rotating inside the mounting base 350, a mounting plate 360 ​​fixed to one side of the rotating block 351, a first sleeve 370 fixed to the middle of one side of the mounting plate 360, a limit groove 371 opened on one side edge of the first sleeve 370, a limit block 372 symmetrically connected inside the limit groove 371, a second sleeve 390 symmetrically fixed to one side of the mounting plate 360, and a limit rod 391 symmetrically fixed to one side of the pressure plate 382; the first knob 38 The outer side of the first sleeve 370 is provided with anti-slip texture. The other end of the first screw 380 is fixed with a first baffle, and the first baffle is located inside the first sleeve 370. The limiting block 372 is fixed to one side of the first knob 381. The limiting rod 391 slides inside the second sleeve 390, and one end of the limiting rod 391 is fixed with a second baffle, which is located inside the second sleeve 390. The slider 321 and the slide groove 320 are T-shaped. A handle is fixed to the middle of one side of the pressure plate 382. Tempered glass is fixed inside the observation window 200. By using the clamping mechanism 300, the L-shaped plate 310 and the... The outer side of the steel structure is fitted, and then the pressure plate 382 is pulled to position the first screw 380 and the limiting rod 391 inside the placement groove 341. The first knob 381 is rotated, which causes the first screw 380 to move, driving the pressure plate 382 to move, so that the pressure plate 382 presses the force plate 340, thereby pressing the clamping plate 330 against the steel structure, thus fixing the windbreak plate 100. This facilitates the installation of the windbreak plate 100, saves installation time, improves installation efficiency, and the windbreak plate 100 is not easily blown away when the wind is strong, forming an effective windproof barrier, improving the windproof effect, and avoiding affecting welding.

[0025] Please see Figure 4 and Figure 5The ventilation adjustment mechanism 400 includes a ventilation opening 410 extending through the top of one side of the wind deflector 100. A mounting frame 420 is fixed to the top of one side of the wind deflector 100. Rotating shafts 430 are evenly rotatably inserted through both sides of the mounting frame 420. Adjusting plates 440 are fixed to opposite sides of the two rotating shafts 430. A gear 450 is fixed to one end of each rotating shaft 430. A bearing 460 is embedded in the center of the top of the mounting frame 420. Connecting rods 470 are symmetrically fixed to the top of the mounting frame 420. A movable plate 480 slides on the outer side of the connecting rod 470. A rack 481 is symmetrically fixed to the bottom of the movable plate 480. A second screw 490 is fixed to the inner ring sidewall of the bearing 460. A second knob 491 is fixed to the top of the second screw 490. The rack 481... Engaged with gear 450, the movable plate 480 is screwed to the outside of the second screw 490. Utilizing the ventilation adjustment mechanism 400, to meet the ventilation requirements during welding, rotating the second knob 491 causes the second screw 490 to rotate. The connecting rod 470 limits the movement of the movable plate 480, causing it to descend outside the connecting rod 470. This, in turn, causes the rack 481 to descend, driving the gear 450 to deflect. This causes the rotating shaft 430 to deflect the adjustment plate 440, allowing some air to enter one side of the windbreak plate 100 through the vent 410, ensuring airflow during welding. In strong winds, the adjustment plate 440 can be closed to avoid wind interference, facilitating adjustment as needed and enhancing the device's practicality.

[0026] In use, the following steps are taken: First, install the windshield 100, attaching the L-shaped plate 310 to the outer side of the steel structure. Then, pull the pressure plate 382, ​​positioning the first screw 380 and the limiting rod 391 inside the placement groove 341. Rotate the first knob 381; with the cooperation of the limiting rod 391 and the second sleeve 390, the first screw 380 moves as the first knob 381 rotates, causing the pressure plate 382 to move. This pressure plate 382 then presses against the force-bearing plate 340, causing the force-bearing plate 340 to move the clamping plate 330. When the clamping plate 330 is in contact with the steel structure, continue rotating the first knob 381, causing the pressure plate 382 to press firmly against the force-bearing plate 340. The clamping plate 330 presses the steel structure to fix the wind deflector 100, facilitating its installation. When airflow is required for welding, the second knob 491 is turned, causing the second screw 490 to rotate. The connecting rod 470 limits the movement of the moving plate 480, causing the rack 481 to descend and the gear 450 to deflect. This causes the rotating shaft 430 to deflect the adjusting plate 440, allowing some air to enter one side of the wind deflector 100 through the vent 410, ensuring airflow during welding. When the wind is strong, turning the second knob 491 in the opposite direction closes the adjusting plate 440, preventing wind from affecting the welding process.
