Description

Technical Field

[0001] This application relates to the technical field of equipment for producing air defense doors, and in particular to an auxiliary welding platform based on air defense doors. Background Technology

[0002] Civil defense doors are a type of civil defense protection equipment with high requirements for airtightness. In wartime, they can prevent chemical and biological agents from entering the interior of civil defense projects through the entrance. The door leaf of a civil defense door is welded from a frame and a panel, and is the main component that withstands shock waves. The frame is generally made of horizontal and vertical channel steel and I-beams welded together. Due to the large number of channel steel and I-beams, the number of weld passes is also large, and full welding is required, resulting in significant welding deformation.

[0003] The existing announcement number CN210818185U, entitled "An Auxiliary Welding Platform for a Civil Defense Door," includes a rectangular workbench, a processing platform rotatably mounted on the upper surface of the workbench, and a lifting device mounted on the lower surface of the workbench. A drive assembly for rotating the processing platform is provided on the lower surface of the workbench. The drive assembly includes a rotating shaft fixed to the lower surface of the processing platform, a worm gear fixed to the rotating shaft and located below the workbench, and a worm cooperating with the worm gear and rotatably mounted on the lower surface of the workbench. The rotating shaft passes vertically through the workbench and extends downwards. One end of the worm gear is fixed to a handwheel for easy rotation by the worker. This provides an auxiliary welding platform for a civil defense door, which has the advantages of facilitating welding for workers, reducing labor intensity, and increasing welding efficiency.

[0004] Regarding the aforementioned technologies, the inventors discovered that during the welding production of air-raid shelter doors, the frame needs to be welded. This usually involves vertically placing the channel steel and I-beams, then using a lifting platform to assist personnel in lifting and lowering the frame for welding at different positions. During welding, the frame needs to be vertically fixed first, requiring multiple horizontal and vertical channel steels and I-beams to be pre-positioned vertically. This process is cumbersome and inefficient. Utility Model Content

[0005] To overcome the limitations of existing methods that utilize lifting platforms to assist personnel in welding different positions of vertical frames, which require pre-positioning multiple horizontal and vertical channel steels and I-beams, resulting in cumbersome steps and low efficiency, this application provides an auxiliary welding platform based on a civil defense door.

[0006] The auxiliary welding platform based on air-raid shelter doors provided in this application adopts the following technical solution:

[0007] An auxiliary welding platform based on a civil defense door includes a support component, a lateral sliding component, and a lifting component. The support component includes a support frame with a skeleton component of the civil defense door horizontally mounted on it. A rod is horizontally fixed to the vertical end face of one side of the support frame. The lateral sliding component includes a lateral sliding groove plate, which is horizontally slidably assembled on the rod. A hydraulic rod is horizontally fixed to the bottom surface of the lateral sliding groove plate away from the support frame. The lifting component includes a guide plate and a bracket. The guide plate is vertically positioned above the lateral sliding groove plate, and the lateral sliding groove plate is horizontally slidably assembled on the guide plate. A sleeve frame is horizontally fixed to one end of the bracket, and the sleeve frame is vertically slidably assembled on the guide plate. A support plate is horizontally fixed to the other end of the bracket.

[0008] By adopting the above technical solution, multiple horizontal and vertical channel steels and I-beams required for the processing and welding of the air-raid shelter door are pre-placed horizontally on the support frame according to the design requirements of the air-raid shelter door. Then, the welding personnel sit on the support plate of the lifting component. During welding, according to the welding positions of the multiple horizontal and vertical channel steels and I-beams, the horizontal sliding plate on the horizontal sliding component is activated to move horizontally on the support frame's frame. The horizontal sliding in the X-axis direction switches the horizontal welding positions of the multiple horizontal and vertical channel steels and I-beams. Then, the guide plate of the lifting component is activated to move horizontally in the horizontal sliding plate, and the horizontal sliding in the Y-axis direction switches the horizontal welding positions of the multiple horizontal and vertical channel steels and I-beams. The horizontal movement switches between multiple horizontal and vertical channel steel and I-beam horizontal welding positions. The starting frame moves vertically on the guide plate, and the horizontal movement in the Z-axis direction switches between multiple horizontal and vertical channel steel and I-beam horizontal welding positions. Therefore, it is not necessary to fix the frame vertically before welding. Multiple horizontal and vertical channel steel and I-beams are pre-positioned horizontally in the support frame, and then the support frame is used to clamp and position multiple horizontal and vertical channel steel and I-beams. This avoids and reduces the steps of vertically supporting multiple horizontal and vertical channel steel and I-beams, improving fixing efficiency. At the same time, welding in the horizontal direction makes the welding points more convenient.

[0009] Optionally, multiple screw hole plates are vertically fixed on the top surface of the support frame, and each screw hole plate is vertically threaded with a pressing screw.

[0010] By adopting the above technical solution, when multiple horizontal and vertical channel steels and I-beams are fixed horizontally on the support frame, the downward pressing screw on the rotating screw plate presses down to clamp the multiple horizontal and vertical channel steels and I-beams in the support frame to maintain stability.

[0011] Optionally, multiple soft pads are evenly and vertically fixed on the bottom surface of the inner wall of the support frame, and a pressure plate is rotatably connected to the bottom end of the pressing screw.

[0012] By adopting the above technical solution, multiple soft pads installed on the inner wall of the support frame are pressed down by the pressure plate at the bottom of the downward screw to clamp the horizontal and vertical channel steel and I-beams in the support frame to maintain stability.

[0013] Optionally, the rod frame is horizontally rotatably connected to a first screw, and one end of the rod frame is horizontally fixed to a first motor, with the output end of the first motor fixed to the end of the first screw.

[0014] By adopting the above technical solution, multiple horizontal and vertical channel steel and I-beam horizontal welding positions can be switched in the X-axis direction. The first motor is started to drive the first screw to move horizontally on the frame, which facilitates the switching of multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the X-axis direction.

[0015] Optionally, one end of the transverse sliding plate is horizontally fixed with a screw hole slider, and the screw hole slider is horizontally slidably assembled in the rod frame, and the screw hole slider is horizontally threaded through the first screw rod.

[0016] By adopting the above technical solution, the first screw rotates in the rod frame during use, driving the screw hole slider at the end of the transverse channel plate to move laterally, and switching multiple horizontal and vertical channel steels and I-beams horizontal welding positions in the X-axis direction.

[0017] Optionally, a slider is fixed on the bottom surface of the guide plate, and the slider is horizontally slidably assembled in the transverse sliding groove plate, with the bottom end of the slider fixedly connected to the output end of the hydraulic rod.

[0018] By adopting the above technical solution, the slider on the bottom surface of the guide plate slides horizontally in the transverse channel plate. The bottom end of the slider is fixedly connected to the output end of the hydraulic rod, which facilitates the transverse switching of multiple horizontal and vertical channel steels and I-beams in the Y-axis direction for horizontal welding.

[0019] Optionally, a second motor is vertically fixed on the top surface of the guide plate, and a second screw is vertically fixed at the bottom end of the second motor.

[0020] By adopting the above technical solution, when switching between multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Z-axis direction, the second motor is started to drive the second screw to rotate, thereby switching between multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Z-axis direction.

[0021] Optionally, a screw hole block is horizontally fixed on the outer end face of the sleeve, and the screw hole block is threaded through and assembled with the second screw.

[0022] By adopting the above technical solution, the second screw and the screw hole block at the end of the sleeve are threaded through and assembled, which facilitates the vertical driving of the sleeve to slide on the guide plate and to switch multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Z-axis direction.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, multiple horizontal and vertical channel steels and I-beams required for the processing and welding of the air-raid shelter door are pre-positioned horizontally on the support frame according to the design requirements of the air-raid shelter door. Then, the welding personnel sit on the support plate of the lifting component. During welding, based on the welding positions of the multiple horizontal and vertical channel steels and I-beams, the horizontal sliding plate on the horizontal sliding component is activated to move horizontally on the support frame's struts, switching the horizontal welding positions of the multiple horizontal and vertical channel steels and I-beams in the X-axis direction. Then, the guide plate of the lifting component is activated to move horizontally within the horizontal sliding plate. The system moves horizontally along the Y-axis to switch between multiple horizontal and vertical channel steel and I-beam horizontal welding positions. The frame moves vertically on the guide plate and horizontally along the Z-axis to switch between the same positions. This eliminates the need to pre-fix the frame vertically during welding; instead, multiple horizontal and vertical channel steel and I-beams are pre-positioned horizontally within the support frame. The support frame then clamps and positions these steels, reducing the need for vertical support and improving fixing efficiency. Furthermore, horizontal welding makes the welding points more convenient. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an auxiliary welding platform based on a civil defense door. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 An auxiliary welding platform based on a civil defense door includes a support component 1, a transverse component 2, and a lifting component 3. The support component 1 includes a support frame 11, on which the skeleton components of the civil defense door are horizontally arranged, and a rod 16 is horizontally fixed on the vertical end face of one side of the support frame 11. The transverse component 2 includes a transverse sliding plate 21, which is horizontally slidably assembled on the rod 16, and a hydraulic rod 23 is horizontally fixed at the bottom surface of the transverse sliding plate 21 away from the support frame 11. The lifting component 3 includes a guide plate 31 and a bracket 35. The guide plate 31 is vertically arranged above the transverse sliding plate 21, and the transverse sliding plate 21 is horizontally slidably assembled on the guide plate 31. A sleeve frame 36 is horizontally fixed at one end of the bracket 35, and the sleeve frame 36 is vertically slidably assembled on the guide plate 31. A support plate 38 is horizontally fixed at the other end of the bracket 35.

[0032] By adopting the above technical solution, multiple horizontal and vertical channel steels and I-beams required for the processing and welding of the air-raid shelter door are pre-placed horizontally on the support frame 11 according to the design requirements of the air-raid shelter door. Then, the welding personnel sit on the support plate 38 of the lifting component 3. During welding, according to the welding positions of the multiple horizontal and vertical channel steels and I-beams, the horizontal sliding plate 21 on the horizontal sliding component 2 is activated to move horizontally on the rod 16 of the support frame 11. The horizontal sliding in the X-axis direction switches the horizontal welding positions of the multiple horizontal and vertical channel steels and I-beams. Then, the guide plate 31 of the lifting component 3 is activated to move horizontally in the horizontal sliding plate 21. The frame 36 moves horizontally along the Y-axis to switch between multiple horizontal and vertical channel steels and I-beams for horizontal welding. The frame 36 moves vertically on the guide plate 31 and moves horizontally along the Z-axis to switch between multiple horizontal and vertical channel steels and I-beams for horizontal welding. Therefore, it is not necessary to fix the frame vertically before welding. Multiple horizontal and vertical channel steels and I-beams are placed horizontally in the support frame 11 beforehand. Then, the support frame 11 is used to clamp and position multiple horizontal and vertical channel steels and I-beams. This avoids and reduces the steps of vertically supporting multiple horizontal and vertical channel steels and I-beams, improving the fixing efficiency. At the same time, welding in the horizontal direction makes the welding points more convenient.

[0033] Reference Figure 3 Multiple screw-hole plates 12 are vertically fixed to the top surface of the support frame 11, and vertically threaded screw rods 13 are assembled on the screw-hole plates 12. When multiple horizontal and vertical channel steels and I-beams are fixed horizontally on the support frame 11, the screw rods 13 on the screw-hole plates 12 are rotated to press and clamp the multiple horizontal and vertical channel steels and I-beams downwards, keeping them stable in the support frame 11. Multiple soft pads 15 are evenly and vertically fixed to the bottom surface of the inner wall of the support frame 11, and a pressure plate 14 is rotatably connected to the bottom end of the screw rod 13. The multiple soft pads 15 on the inner wall of the support frame 11 are pressed and clamped downwards by the pressure plate 14 at the bottom end of the screw rod 13, keeping the horizontal and vertical channel steels and I-beams stable in the support frame 11.

[0034] Reference Figure 3A first screw 17 is horizontally rotatably connected inside the frame 16, and a first motor 18 is horizontally fixed to one end of the frame 16, with the output end of the first motor 18 fixed to the end of the first screw 17. Multiple horizontal and vertical channel steel and I-beam horizontal welding positions are switched by lateral movement in the X-axis direction. The first motor 18 is started to drive the first screw 17 to move horizontally on the frame 16, facilitating the lateral movement and switching of multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the X-axis direction. A threaded slider 22 is horizontally fixed to one end of the transverse sliding plate 21, and the threaded slider 22 is horizontally slidably assembled in the frame 16, with the threaded slider 22 and the first screw 17 horizontally threaded through each other. In use, the first screw 17 rotates in the frame 16, driving the threaded slider 22 at the end of the transverse sliding plate 21 to move laterally, switching multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the X-axis direction.

[0035] Reference Figure 5 A slider 32 is fixed to the bottom surface of the guide plate 31, and the slider 32 is horizontally slidably assembled in the transverse sliding groove plate 21. The bottom end of the slider 32 is fixedly connected to the output end of the hydraulic rod 23. During use, the slider 32 on the bottom surface of the guide plate 31 slides horizontally in the transverse sliding groove plate 21, and the bottom end of the slider 32 is fixedly connected to the output end of the hydraulic rod 23, which facilitates the horizontal switching of multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Y-axis direction. A second motor 33 is vertically fixed to the top surface of the guide plate 31, and a second screw 34 is vertically fixed to the bottom end of the second motor 33. When switching multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Z-axis direction, the second motor 33 is started to drive the second screw 34 to rotate, thus switching multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Z-axis direction. A screw hole block 37 is horizontally fixed to the outer end face of the sleeve 36, and the screw hole block 37 is threaded through the second screw 34. The second screw 34 is threaded through the screw hole block 37 at the end of the sleeve 36, which facilitates the vertical driving of the sleeve 36 to slide on the guide plate 31 and to switch multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Z-axis direction.

[0036] The implementation principle of an auxiliary welding platform based on a civil defense door in this application embodiment is as follows: During use, multiple horizontal and vertical channel steels and I-beams required for the processing and welding of the civil defense door are pre-placed horizontally on the support frame 11 according to the design requirements of the civil defense door. When the multiple horizontal and vertical channel steels and I-beams are fixed horizontally on the support frame 11, the downward pressing screw 13 on the rotating screw plate 12 presses downward to clamp the multiple horizontal and vertical channel steels and I-beams, keeping them stable in the support frame 11. Then, the welding personnel sit on the support plate 38 of the lifting component 3. During welding, according to the welding position of the multiple horizontal and vertical channel steels and I-beams, the horizontal welding position of the multiple horizontal and vertical channel steels and I-beams is switched laterally in the X-axis direction. The first motor 18 is started to drive the first screw 17 to move horizontally on the frame 16, facilitating the horizontal switching of the multiple horizontal and vertical channel steels and I-beams in the X-axis direction. The horizontal moving plate 21 on the horizontal moving component 2 is then activated. The frame moves horizontally on the support frame 11 and the rod 16 moves horizontally in the X-axis direction to switch multiple horizontal and vertical channel steel and I-beam horizontal welding positions. Then, the guide plate 31 of the lifting component 3 is started to move horizontally in the horizontal moving slot plate 21. The slider 32 on the bottom surface of the guide plate 31 slides horizontally in the horizontal moving slot plate 21. The bottom end of the slider 32 is fixedly connected to the output end of the hydraulic rod 23 to facilitate the horizontal switching of multiple horizontal and vertical channel steel and I-beam horizontal welding positions in the Y-axis direction. When the frame 36 moves vertically on the guide plate 31, it moves horizontally in the Z-axis direction to switch multiple horizontal and vertical channel steel and I-beam horizontal welding positions. When the frame 36 moves horizontally in the Z-axis direction to switch multiple horizontal and vertical channel steel and I-beam horizontal welding positions, the second motor 33 is started to drive the second screw 34 to rotate, and the frame 36 moves horizontally in the Z-axis direction to switch multiple horizontal and vertical channel steel and I-beam horizontal welding positions.
