Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, and in particular to an auxiliary support device for the installation of heavy-duty civil defense doors. Background Technology

[0002] Civil defense doors are the entrances and exits of civil defense projects. They are clearly categorized, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, among other types. During the installation of civil defense doors, auxiliary support equipment is needed to replace manual support, especially for heavy-duty civil defense doors.

[0003] A search revealed a support device for installing air-raid shelter doors, with announcement number CN221053089U. This device relates to the field of air-raid shelter door installation technology and includes a base. Rollers are installed at the bottom of the base, and a hinged seat is fixedly connected to the top of the base. A flip plate is rotatably connected to the hinged seat, and hydraulic components for driving the flip plate to flip are installed on both sides of the base.

[0004] Based on the aforementioned patents, the existing technology has the following shortcomings: the existing support device for installing air-raid shelter doors uses a horizontal clamping mechanism to clamp the air-raid shelter door onto a flip plate. In this case, the width of the clamping mechanism and the flip plate must be greater than the width of the air-raid shelter door, resulting in a large gap between the air-raid shelter door and the installation structure on the wall. This makes it impossible to effectively connect the air-raid shelter door to the installation structure on the wall. Therefore, it is urgent to design a heavy-duty auxiliary support device for installing air-raid shelter doors to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary support device for the installation of heavy-duty air-raid shelter doors. Its advantage lies in enabling the heavy-duty air-raid shelter door to move back and forth, gradually bringing it closer to the wall installation position, thus facilitating installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary support device for installing a heavy-duty air-raid shelter door includes an L-shaped support plate. A mounting base is fixed to one top end of the L-shaped support plate, and a tilting support platform for placing the heavy-duty air-raid shelter door is rotatably connected to the mounting base via a pin. A traction mechanism is provided at the top of one end of the L-shaped support plate, and a lifting plate for placing the heavy-duty air-raid shelter door is installed at one end of the traction mechanism. The top surface of the lifting plate is flush with the top surface of the tilting support platform. A clamping assembly is provided at the top of the lifting plate. The L-shaped support plate has equidistantly distributed first connecting grooves on the side near the tilting support platform, and first sliding rollers are rotatably connected to the inner walls of each of the first connecting grooves. The tilting support platform has equidistantly distributed second connecting grooves on one side, and second sliding rollers are rotatably connected to the inner walls of each of the second connecting grooves.

[0008] The above technical solution enables the horizontally placed air-raid shelter door to be flipped into a vertical position. Through the sliding action of the first and second sliding rollers, the heavy-duty air-raid shelter door gradually approaches the wall installation position, achieving a rapid docking effect and facilitating installation.

[0009] The present invention is further configured such that the clamping assembly includes a fixing plate fixedly installed on one side of the top of the lifting plate, and a plurality of hydraulic cylinders are fixedly installed on one side of the fixing plate, and an L-shaped clamping plate is fixedly installed on the piston end of the hydraulic cylinder.

[0010] The above technical solutions can clamp and fix heavy-duty air-raid shelter doors during rotation, preventing them from slipping.

[0011] The present invention is further configured such that the traction mechanism includes a traction machine fixedly installed at the top of one end of the L-shaped support plate, and a traction rope is wound on the traction machine, with one end of the traction rope fixedly installed at the top middle position of the fixed plate.

[0012] The above technical solutions facilitate the rotation of the lifting plate, thereby enabling the heavy-duty air-raid shelter door to be flipped.

[0013] The present invention is further configured such that two arc-shaped rail frames are fixedly installed on the L-shaped support plate, and support rods are fixed on the top of the opposite sides of the two arc-shaped rail frames. A support wheel is rotatably connected to the middle position of the support rod, and the traction rope is laid on the support wheel.

[0014] The above technical solutions facilitate the support of the traction rope.

[0015] The present invention is further configured such that both ends of one side of the lifting plate are fixed with slide blocks that pass through the arc-shaped rail frame, and two pulleys are rotatably connected to the inner walls of both sides of the slide blocks, and the pulleys slide on the surface of the arc-shaped rail frame.

[0016] The present invention is further configured such that an arc-shaped guide rod is fixed at the middle position of the inner wall of the arc-shaped rail frame, and guide holes for the arc-shaped guide rod to pass through are provided on both slides.

[0017] The above technical solutions ensure more stable operation of the slide and lifting plate.

[0018] The present invention is further configured such that an auxiliary bracket is fixedly installed at the bottom of one end of the L-shaped support plate, and multiple movable wheels are installed at the bottom of both the auxiliary bracket and the bottom of the L-shaped support plate.

[0019] The above technical solutions enhance the overall support effect of the device and make it easier to move.

[0020] The present invention is further configured such that the traction machine is connected to a switch via a wire, and the switch is connected to a power source via a wire, and the hydraulic cylinder is connected to a hydraulic system.

[0021] The above technical solutions facilitate the control of the entire device during operation.

It can flip a horizontally placed air defense door into a vertical position. By moving the entire device, it is easy to bring the heavy-duty air defense door closer to the installation position, making it convenient to use.

[0024] 2. The auxiliary support equipment for installing this heavy-duty air-raid shelter door uses clamping components to hold and fix the heavy-duty air-raid shelter door during the flipping process, preventing it from falling off. During installation, the clamping components are released, and the heavy-duty air-raid shelter door is moved back and forth by manual pushing through the sliding action of the first and second sliding rollers, gradually bringing it closer to the wall installation position. This solves the problem of large gaps between the air-raid shelter door and the wall installation structure in existing technologies, achieving a rapid connection effect and facilitating installation.

[0035] Reference Figure 1-5A heavy-duty air-raid shelter door installation auxiliary support device includes an L-shaped support plate 1. A mounting base 14 is fixed to one top end of the L-shaped support plate 1, and a tilting support platform 2 for placing the heavy-duty air-raid shelter door is rotatably connected to the mounting base 14 via a pin. A traction mechanism is provided at the top of one end of the L-shaped support plate 1, and a lifting plate 12 for placing the heavy-duty air-raid shelter door is installed at one end of the traction mechanism. The top surface of the lifting plate 12 is flush with the top surface of the tilting support platform 2. A clamping assembly 10 is provided at the top of the lifting plate 12. The clamping assembly 10 includes a fixing plate 1001 fixedly installed on one side of the top of the lifting plate 12, and multiple hydraulic cylinders 1002 are fixedly installed on one side of the fixing plate 1001. An L-shaped clamping plate 1003 is fixedly installed at the piston end of each hydraulic cylinder 1002. The traction mechanism includes a traction machine 6 fixedly installed at the top of one end of the L-shaped support plate 1, and a traction rope 9 is wound around the traction machine 6. One end is fixedly installed at the top center of the fixed plate 1001. The L-shaped support plate 1 has a first connecting groove 13 with equal spacing on the side near the flip support platform 2. The inner wall of the first connecting groove 13 is rotatably connected to the first sliding roller 4. The side of the flip support platform 2 has a second connecting groove 19 with equal spacing. The inner wall of the second connecting groove 19 is rotatably connected to the second sliding roller 18. The traction machine 6 in the traction mechanism drives the traction rope 9 to be wound up, which drives the lifting plate 12, the heavy-duty air-raid shelter door and the flip support platform 2 to rotate. This can flip the horizontally placed air-raid shelter door into a vertical state. By moving the entire device, it is easy to bring the heavy-duty air-raid shelter door closer to the installation position. Then, through the sliding action of the first sliding roller 4 and the second sliding roller 18, the heavy-duty air-raid shelter door is moved back and forth by manual pushing, so that the heavy-duty air-raid shelter door gradually approaches the wall installation position, achieving a rapid docking effect and facilitating installation.

[0036] Specifically, two arc-shaped rail frames 5 are fixedly installed on the L-shaped support plate 1, and support rods 7 are fixed on the top of the opposite sides of the two arc-shaped rail frames 5. A support wheel 8 is rotatably connected to the middle position of the support rod 7, and the traction rope 9 is laid on the support wheel 8 to facilitate the support of the traction rope 9.

[0037] Specifically, both ends of one side of the lifting plate 12 are fixed with slide blocks 11 that pass through the arc-shaped rail frame 5, and two pulleys 17 are rotatably connected to the inner walls of both sides of the slide blocks 11. The pulleys 17 slide on the surface of the arc-shaped rail frame 5. An arc-shaped guide rod 15 is fixed in the middle of the inner wall of the arc-shaped rail frame 5, and guide holes 16 are opened on both slide blocks 11 for the arc-shaped guide rod 15 to pass through. The sliding action of the pulleys 17 and the guiding action of the arc-shaped guide rod 15 ensure that the operation of the slide blocks 11 and the lifting plate 12 is more stable.

[0038] Specifically, an auxiliary support 3 is fixedly installed at the bottom of one end of the L-shaped support plate 1, and multiple movable wheels are installed at the bottom of both the auxiliary support 3 and the bottom of the L-shaped support plate 1. The auxiliary support 3 increases the support effect of the entire device, and the movable wheels make the entire device easy to move.

[0039] Specifically, the traction machine 6 is connected to a switch via a wire, and the switch is connected to a power source via a wire. The hydraulic cylinder 1002 is connected to a hydraulic system, which facilitates the control of the entire device.

[0040] Working principle: During use, the staff first lifts the heavy-duty air-raid shelter door onto the flip support platform 2 and the lifting plate 12. The hydraulic cylinder 1002 in the clamping assembly 10 is used to adjust the position of the L-shaped clamp 1003, so that the heavy-duty air-raid shelter door is clamped between the second sliding roller 18 and the L-shaped clamp 1003. Then, the staff drives the traction rope 9 to wind up through the traction machine 6 in the traction mechanism, which drives the lifting plate 12, the heavy-duty air-raid shelter door and the flip support platform 2 to rotate, thereby flipping the horizontally placed heavy-duty air-raid shelter door into a vertical state. Then, the entire device is moved by the moving wheels to bring the heavy-duty air-raid shelter door closer to the installation position. When it is time to install, the staff releases the clamping assembly 10, so that the L-shaped clamp 1003 is detached from the heavy-duty air-raid shelter door. Then, the sliding action of the first sliding roller 4 and the second sliding roller 18, combined with manual pushing, moves the heavy-duty air-raid shelter door back and forth, so that the heavy-duty air-raid shelter door gradually approaches the wall installation position, achieving rapid docking.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
