Description

Technical Field

[0001] This application relates to the field of welding protection technology, and in particular to a welding protection device for server racks. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. It is an indispensable component of electrical equipment and serves as the carrier for electrical control devices. It provides protection against water, dust, and electromagnetic interference, and is widely used in industries such as chemical engineering, environmental protection, power systems, metallurgy, industry, nuclear power, fire safety monitoring, and transportation.

[0003] Currently, server racks are generally made of cold-rolled steel plates. Because server racks are often quite large, during the manufacturing process, workers need to use a welding torch to weld the steel plates. During the welding process, workers typically hold the welding torch while simultaneously holding a protective mask to complete the welding of the server rack.

[0004] Regarding the aforementioned technologies, the inventors discovered that the welding process for server racks generates a large amount of waste gas, which will first diffuse into the indoor environment, reducing the quality of the indoor environment and posing a potential hazard to the health of workers. Summary of the Invention

[0005] To alleviate the problem of exhaust fumes easily spreading into the indoor environment and posing a health hazard to workers during server rack welding, this application provides a server rack welding protection device.

[0006] This application provides a cabinet welding protection device, which adopts the following technical solution:

[0007] A cabinet welding protection device includes a gripping rod, a protective cover, and an exhaust gas treatment mechanism. The protective cover is fixedly connected to the gripping rod and is used to cover the welding position of the cabinet. The welding torch is disposed inside the protective cover. The exhaust gas treatment mechanism is disposed on the protective cover and is used to treat the exhaust gas inside the protective cover.

[0008] By adopting the above technical solution, the welding torch is placed inside the protective cover. When welding the cabinet, the worker holds the handle and covers the protective cover with the position of the cabinet to be welded, and then starts the welding torch to weld the cabinet. The exhaust gas generated during the welding process is blocked inside the protective cover. At the same time, the exhaust gas treatment mechanism is used to extract and treat the exhaust gas inside the protective cover, reducing the possibility of exhaust gas directly spreading into the indoor environment and reducing the harm to the health of the workers.

[0009] Preferably, the welding torch is detachably fixed inside the protective cover.

[0010] By adopting the above technical solution, the welding gun is detachably connected inside the protective cover. When encountering welding positions with limited space, such as cabinet corners, workers can remove the welding gun from the protective cover for use, improving the flexibility of the welding gun during use. When welding the cabinet with the welding gun removed, workers can continue to hold the protective cover to protect their faces without the need for an additional protective mask, thus improving the functionality of the protective cover.

[0011] Preferably, a support block is fixedly connected inside the protective cover, the support block has a support groove, a support rod is engaged in the support groove, the welding torch is mounted on the support rod, and a locking mechanism is provided on the protective cover for locking the support rod onto the support block.

[0012] By adopting the above technical solution, the welding gun is placed on the support rod, and after the support rod is snapped into the support groove, the support rod is locked using the locking mechanism, thus realizing the installation of the welding gun. When welding is required in small spaces such as corners of the cabinet, the locking mechanism is released from the support rod, and then the support rod is removed. The worker holds a protective shield to protect their face with one hand, and holds the support rod with the other hand to weld the cabinet with the welding gun.

[0013] Preferably, a movable block is slidably connected to the support rod, the welding torch is disposed on the movable block, and a pushing component is disposed on the protective cover, the pushing component being used to push the movable block to slide.

[0014] By adopting the above technical solution, after the protective cover is placed on the cabinet, the staff can use the pushing component to push the moving block to slide, which will cause the moving block to move the welding gun, so that the welding gun can weld a certain distance on the cabinet. Then the protective cover can be moved to weld the next section of the cabinet, thus gradually completing the welding of the entire cabinet. This reduces the frequency of moving the protective cover, thereby reducing the amount of exhaust gas leaking out.

[0015] Preferably, the protective cover is provided with a collection mechanism, which includes an adjustment component and two collection plates. The two collection plates are respectively installed on opposite side walls of the protective cover. Each collection plate is slidably connected to the protective cover. The adjustment component is connected to the protective cover, and both collection plates are connected to the adjustment component. The adjustment component drives the two collection plates to slide in a direction that moves closer to or further away from each other.

[0016] By adopting the above technical solution, when welding the cabinet, the two collecting plates can be moved closer to each other by using the adjustment component, so that the two collecting plates are moved to the positions on both sides of the welding gun. Most of the welding slag that splashes during the welding process will fall onto the two collecting plates, thus facilitating the collection of the splashed welding slag. When the welding gun is removed and the protective cover is held to protect one's face, the two collecting plates can be moved further apart, so that the two collecting plates extend beyond the sides of the protective cover, which can significantly increase the protection range and improve the safety of workers during welding.

[0017] Preferably, the adjusting assembly includes a rotating rod, a first gear, and two racks. The rotating rod is rotatably connected to the protective cover. The first gear is coaxially and fixedly connected to the rotating rod. The two racks are arranged one-to-one with the two collecting plates. Each rack is fixedly connected to the collecting plate it corresponds to. Both racks are meshed with the first gear. The two racks are located on opposite sides of the first gear.

[0018] By adopting the above technical solution, the operator can rotate the rotating rod to drive the first gear, which is fixedly connected to it on the same axis, to rotate. The rotation of the first gear will drive the two racks to move synchronously in opposite directions, which in turn can drive the two collecting plates to move in a direction that is closer to or further away from each other, thus improving the convenience of adjusting the position of the two collecting plates.

[0019] Preferably, the locking mechanism includes a second gear, a third gear, a screw, a support block, and a locking block. The support block is fixedly connected inside the protective cover. The screw is threadedly connected to the support block. The second gear is coaxially fixedly connected to the rotating rod. The third gear is coaxially fixedly connected to the screw. The second gear and the third gear are meshed together. The locking block is slidably connected inside the protective cover. The screw is rotatably connected to the locking block. The locking block, driven by the screw, presses the support rod against the screw.

[0020] By adopting the above technical solution, after the support rod is placed in the support groove, rotating the rotating rod drives the two collecting plates to move closer to each other. At the same time, the rotating rod can drive the second gear to rotate. The rotation of the second gear will drive the rotation of the third gear meshing with it. By using the screw threaded connection between the screw and the support block, the third gear and the screw will move down synchronously during the rotation. Then, the screw will push the locking block down, so that the locking block will press the support rod against it. At this time, the screw threaded engagement with the support block can simultaneously restrict the rotation of the rotating rod, ensuring the stability of the two collecting plates during use. After use, rotating the rotating rod in the opposite direction will drive the two collecting plates to move away from each other. At the same time, the screw and the locking block will move back, releasing the locking of the support rod, so that the support rod can be removed. This allows for welding of cabinets in small spaces.

[0021] Preferably, the support rod is hollow and has multiple air intake holes. A vent pipe is fixedly connected to the protective cover, and the vent pipe connects the inner and outer sides of the protective cover. When the locking mechanism locks the support rod, the interior of the support rod is connected to the vent pipe, and the exhaust gas treatment mechanism is connected to the vent pipe.

[0022] By adopting the above technical solution, multiple air intake holes are opened on the support rod, and the inside of the support rod is connected to the exhaust gas treatment mechanism through the air pipe. During the welding process of the cabinet, the exhaust gas generated can be discharged to the outside of the protective cover in a timely manner through multiple air intake holes, reducing the possibility of excessive accumulation of exhaust gas inside the protective cover and obstructing the vision of the staff.

[0023] Preferably, the exhaust gas treatment mechanism includes an intake pipe, a fan, and an exhaust gas treatment box. One end of the intake pipe is connected to the interior of the exhaust gas treatment box, and the end of the intake pipe away from the exhaust gas treatment box is detachably connected to the ventilation pipe. The fan is fixedly connected to the exhaust gas treatment box and is used to draw the exhaust gas inside the protective cover into the exhaust gas treatment box.

[0024] By adopting the above technical solution, the suction pipe and the ventilation pipe are detachably connected. When welding is being performed normally in the cabinet, the suction pipe is connected to the inside of the support rod through the ventilation pipe to extract and treat the exhaust gas inside the protective cover. After the support rod is removed from the protective cover, the worker removes the suction pipe from the ventilation pipe at the same time, and then reassembles the removed support rod and suction pipe together. When welding in a small area of ​​the cabinet by holding the support rod, some of the generated fumes can still enter the inside of the support rod through multiple suction holes and then enter the exhaust gas treatment box, reducing the possibility of excessive exhaust gas spreading into the indoor environment.

[0025] Preferably, the suction pipe is threaded with a bolt, the side wall of the vent pipe is provided with a threaded hole, and the side wall of the support rod is provided with another threaded hole.

[0026] By adopting the above technical solution, after threading a bolt onto the intake pipe and fitting the intake pipe onto the outside of the ventilation pipe, tightening the bolt to engage with the threaded hole on the ventilation pipe allows for a detachable connection between the intake pipe and the ventilation pipe. Similarly, after inserting one end of the support rod into the intake pipe and tightening the bolt to engage with the threaded hole on the support rod, a detachable connection between the intake pipe and the support rod can be achieved.

[0027] In summary, this application includes at least the following beneficial technical effects:

[0028] 1. By placing the welding torch inside the protective cover, when welding the cabinet, the worker holds the handle and covers the protective cover with the position of the cabinet to be welded. The exhaust gas generated during the welding process is blocked inside the protective cover. At the same time, the exhaust gas treatment device is used to extract and treat the exhaust gas inside the protective cover, reducing the possibility of exhaust gas directly spreading into the indoor environment and reducing the harm to the health of the workers.

[0029] 2. By detachably connecting the welding torch to the protective cover, workers can easily remove the torch from the cover when encountering welding positions with limited space, such as cabinet corners, increasing the flexibility of the welding torch during use. When welding the cabinet with the torch detached, workers can continue to hold the protective cover to shield their faces, eliminating the need for a separate face shield and enhancing the functionality of the protective cover.

[0030] 3. By sliding the collection plates on both sides of the protective cover, when welding the cabinet, the two collection plates can be moved closer to each other by using the adjustment component. This allows the two collection plates to be moved to the positions on both sides of the welding gun. Most of the welding slag that splashes during the welding process will fall onto the two collection plates, making it easier to collect the splashed welding slag. Attached Figure Description

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0041] This application discloses a cabinet welding protection device.

[0042] Reference Figure 1 and Figure 2 A server rack welding protection device includes a gripping rod 100, a protective cover 200 fixedly connected to the gripping rod 100, an observation port on the top surface of the protective cover 200, and an observation glass 210 fixedly connected to the protective cover 200, which seals the observation port. A welding torch 700 is installed inside the protective cover 200 for welding the server rack. A waste gas treatment mechanism 300 is installed on the protective cover 200 for treating the waste gas generated during the welding process inside the protective cover 200.

[0043] Reference Figure 1 , Figure 2 and Figure 3Inside the protective cover 200, a detachable support rod 400 is fixedly connected. The support rod 400 is arranged along the length of the protective cover 200. Two support blocks 430 are fixedly connected inside the protective cover 200, each with a support groove 431 for receiving the support rod 400. A locking mechanism 600 is installed on the protective cover 200 to lock the support rod 400 between the two support blocks 430. A movable block 410 is sleeved on the outer side of the support rod 400, slidably connected to the support rod 400, and slides along the length of the support rod 400. A welding torch 700 is fixedly connected to the movable block 410. A pushing assembly 420 is installed on the protective cover 200 to push the movable block 410 to slide.

[0044] Reference Figure 2 and Figure 3 The pushing assembly 420 includes a pushing rod 421 that passes through the side wall of the protective cover 200. The length direction of the pushing rod 421 is parallel to the length direction of the support rod 400. The pushing rod 421 is slidably connected to the protective cover 200. An electromagnet 422 is fixedly connected to one end of the pushing rod 421 that passes inside the protective cover 200. The electromagnet 422 is used to attract the moving block 410. A clamping bolt 311 passes through the moving block 410 and is threadedly connected to the moving block 410. The clamping bolt 311 is used to clamp the moving block 410 against the support rod 400. When welding the server rack, after the protective cover 200 is placed on the rack, the welding torch 700 is started. During the welding process, the electromagnet 422 is activated. Under the action of the electromagnet 422, the push rod 421 is fixedly connected to the moving block 410. The push rod 421 pushes the block forward, which in turn moves the welding torch 700 to slide, allowing the welding torch 700 to weld a section of the rack. After welding a section, the protective cover 200 and the welding torch 700 are lifted by holding the lever 100, and then the protective cover 200 is placed on the next section to be welded. Repeat the above operation at the connection point to proceed to the next section of welding; when the support rod 400 is disassembled, the electromagnet 422 is de-energized, then the support rod 400 is removed, and the clamping bolt 311 is tightened to fix the moving block 410 on the support rod 400. The worker can then hold the support rod 400 with one hand to weld in small spaces such as the corner of the cabinet, and hold the grip rod 100 with the other hand to use the protective cover 200 as a face mask to cover the worker's face, improving the flexibility of the protective device.

[0045] Reference Figure 2 and Figure 4In order to facilitate the collection of welding slag splashed during the welding process of the cabinet, a collection mechanism 500 is installed on the protective cover 200. The collection mechanism 500 includes collection plates 510 passing through opposite sides of the protective cover 200. Each collection plate 510 is slidably connected to the side wall of the protective cover 200 through which it passes. An adjustment component 520 is installed on the protective cover 200. The adjustment component 520 is used to push the two collection plates 510 to slide in a direction that moves closer or further away from each other.

[0046] The adjustment assembly 520 includes a rotating rod 521 passing through the top surface of the protective cover 200. The rotating rod 521 is rotatably connected to the protective cover 200, and a first gear 522 is coaxially fixedly connected to the rotating rod 521. The first gear 522 is located inside the protective cover 200. Each collecting plate 510 is fixedly connected to a rack 523, and both racks 523 are meshed with the first gear 522. The two racks 523 are located on opposite sides of the first gear 522. When welding the cabinet, rotating the rotating rod 521 drives the first gear 522 to rotate. The rotation of the first gear 522 drives the two racks 523 meshing with it to move in opposite directions, which in turn drives the two collecting plates 510 to move closer to each other. This allows the two collecting plates 510 to move to both sides of the welding torch 700. During the welding process of the cabinet, most of the welding slag will splash onto the two collecting plates 510, thus facilitating the collection of the splashed welding slag. When welding torch 700 is disassembled and used for welding in small spaces such as corners, rotating rotating rod 521 in the opposite direction will cause the two collecting plates 510 to move away from each other through the cooperation of the first gear 522 and the two racks 523. This will extend the two collecting plates 510 to both sides of the protective cover 200. When the protective cover 200 is used as a protective mask, the protection range will be significantly increased, and the safety of workers during welding will be improved.

[0047] Reference Figure 2 , Figure 4 and Figure 5The locking mechanism 600 includes a second gear 610 coaxially fixedly connected to the rotating rod 521. The second gear 610 is located near the top surface of the protective cover 200, close to the first gear 522. A support block 630 is fixedly connected inside the protective cover 200. A screw 640 passes through the support block 630 and is threadedly connected to it. The axis of the screw 640 is parallel to the rotation axis of the rotating rod 521. A third gear 620 is coaxially fixedly connected to the top of the screw 640. The third gear 620 is located to one side of the second gear 610 and meshes with it. The thickness of the second gear 610 is greater than the thickness of the third gear 620. A locking block 650 is slidably connected inside the protective cover 200. The locking block 650 slides towards or away from the top surface of the protective cover 200. The end of the locking block 650 away from the top surface of the protective cover 200 is inclined, facing the support rod 400. The locking block 650 is located above the support block 430 near the rotating rod 521. The lower end of the locking block 650 can be inserted into the gap between the support rod 400 and the support block 430 near the rotating rod 521. A guide rod 660 is fixedly connected to the locking block 650. The axis of the guide rod 660 is parallel to the axis of the screw 640. The guide rod 660 passes through the support block 630 and is slidably connected to the support block 630. The end of the screw 640 away from the third gear 620 is rotatably connected to the locking block 650, and the screw 640 can push the locking block 650 to slide downward.

[0048] Reference Figure 4 , Figure 5 and Figure 6Before welding the cabinet, the support rod 400, equipped with the welding torch 700, is first placed in the two support grooves 431 on the two support blocks 430. Then, the rotating rod 521 is rotated. As the rotating rod 521 drives the first gear 522 to rotate, driving the two collecting plates 510 to move closer to each other, the rotation simultaneously drives the second gear 610 to rotate. The rotation of the second gear 610 drives the third gear 620, which is meshed with it, to rotate. Since the screw 640 is threadedly connected to the support block 630, the third gear 620 and the screw 640 will move synchronously downwards during the rotation. The screw 640 then pushes the locking block 650 downwards, causing the lower end of the locking block 650 to insert into the gap between the support rod 400 and the support block 430. The inclined surface at the lower end of the locking block 650 allows it to push the support rod 400 to slide to one end, thus locking the support rod 400. After locking the support rod 400, the threaded connection between the screw 640 and the support block 630 limits the third gear 620, which in turn limits the rotating rod 521, ensuring the stability of the two collecting plates 510 during use. When the welding torch 700 needs to be disassembled for welding in small spaces such as corners, the rotating rod 521 is rotated in the opposite direction. This causes the two collecting plates 510 to move away from each other, opening the protective cover 200. At the same time, the screw 640 is driven to move upward with the cooperation of the second gear 610 and the third gear 620. This causes the locking block 650 to move upward, thereby releasing the locking of the support rod 400. Then, the worker can remove the support rod 400 from the two support blocks 430 and hold the support rod 400 to perform welding on the cabinet in the small space.

[0049] Reference Figure 3 and Figure 7 The support rod 400 is hollow and has multiple suction holes 440 along its length. Each suction hole 440 penetrates the outer side and the inner cavity of the support rod 400. The exhaust gas treatment mechanism 300 includes a suction pipe 310 with bolts 311 threadedly connected to its side wall. A vent pipe 450 is fixedly connected to the side wall of the protective cover 200 and communicates with the inside of the support rod 400 locked inside the protective cover 200. One end of the vent pipe 450, away from the support rod 400, extends to the outside of the protective cover 200. The vent pipe 450 has a threaded hole that matches the bolt 311. One end of the support rod 400 has another threaded hole that matches the bolt 311. One end of the suction pipe 310 is fitted onto the outside of the vent pipe 450.

[0050] Reference Figure 1 , Figure 7 and Figure 8The end of the suction pipe 310 away from the vent pipe 450 is fixedly connected to the exhaust gas treatment box 330. The suction pipe 310 communicates with the interior of the exhaust gas treatment box 330. A fan 320 is fixed inside the exhaust gas treatment box 330, which is used to extract waste gas from the protective cover 200 into the exhaust gas treatment box 330. An air inlet is provided on the side wall of the protective cover 200, allowing external air to enter the protective cover 200 and replenish the air inside. During the welding process of the cabinet, the exhaust gas generated inside the protective cover 200 is first drawn into the support rod 400 through multiple suction holes 440 by the fan 320, and then sequentially enters the exhaust gas treatment box 330 through the vent pipe 450 and the suction pipe 310 for treatment. After removing the support rod 400 from the protective cover 200, insert one end of the support rod 400 into the end of the suction pipe 310 away from the exhaust gas treatment box 330, and then screw the bolt 311 into the threaded hole of the support rod 400. When welding at corners or other locations with limited space, some of the generated fumes can still enter the support rod 400 through multiple suction holes 440 and then into the exhaust gas treatment box 330, reducing the possibility of excessive exhaust gas spreading to the surrounding environment.

[0051] Reference Figure 8 The exhaust gas treatment box 330 is equipped with a spray assembly 340. The spray assembly 340 includes a water pump 341 fixedly connected to one side of the exhaust gas treatment box 330. The water inlet of the water pump 341 is connected to a water inlet pipe 342. The end of the water inlet pipe 342 away from the water pump 341 extends into the exhaust gas treatment box 330. The exhaust gas treatment box 330 contains spray water. The water outlet of the water pump 341 is connected to a water outlet pipe 343. The water outlet pipe 343 extends into the exhaust gas treatment box 330. Multiple atomizing nozzles 344 are fixedly connected to the water outlet pipe 343. Each atomizing nozzle 344 is connected to the inside of the spray pipe.

[0052] The exhaust gas treatment box 330 has an outlet 360, and an activated carbon filter 350 is fixedly connected inside the exhaust gas treatment box 330, located near the outlet 360. Exhaust gas entering the exhaust gas treatment box 330 is atomized and sprayed by the atomizing nozzle 344, then filtered by the activated carbon filter 350, and finally discharged into the external environment through the outlet 360. The atomizing nozzle 344 and the activated carbon filter 350 treat various oxide particles and fumes contained in the exhaust gas before it is discharged into the external environment, reducing environmental pollution.

[0053] The implementation principle of the cabinet welding protection device in this application embodiment is as follows: By detachably installing the welding torch 700 inside the protective cover 200, when welding the cabinet, the operator holds the handle 100 and covers the protective cover 200 with the area of ​​the cabinet to be welded. Then, the operator starts the welding torch 700 and moves it by pushing the moving block 410, thus achieving welding of a section of the cabinet. During the welding process, the generated exhaust gas is confined inside the protective cover 200. Simultaneously, the exhaust gas treatment mechanism 300 extracts and treats the exhaust gas inside the protective cover 200, reducing the possibility of the exhaust gas directly diffusing into the indoor environment and minimizing the impact on the indoor environment. The welding torch 700 can be removed from the protective cover 200 when welding in confined spaces such as corners of server racks. While protecting their face with the protective cover 200, workers can use the support rod 400 to weld the server rack, increasing the flexibility of the torch. Furthermore, multiple suction holes 440 on the support rod 400 allow some of the generated fumes to enter the support rod 400 and then the exhaust gas treatment box 330, reducing the possibility of excessive fumes spreading into the indoor environment.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
