Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a quick disassembly auxiliary tool for civil air defense doors. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. When civil defense doors are replaced or maintained, they need to be disassembled, and then civil defense door quick disassembly auxiliary tools need to be used.

[0003] Since the civil air defense door is relatively heavy, when dismantling the civil air defense door, one staff member is required to hold the civil air defense door steady while another staff member dismantles the civil air defense door. After the dismantling is completed, the two staff members slowly lay the civil air defense door down on the transfer cart and use auxiliary tools: the transfer cart to move the civil air defense door to the designated maintenance area for inspection or replacement. In the process of the civil air defense door being slowly laid down on the transfer cart, two people are required to exert force at the same time to lay the civil air defense door down, which requires a lot of manpower and time, which not only wastes time, but also reduces work efficiency.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0024] Reference Figure 1-3, a quick disassembly auxiliary tool for a civil air defense door, comprising a base 1, an auxiliary lifting plate 4 is arranged at the top of the base 1, the top of the auxiliary lifting plate 4 is rotatably connected to an auxiliary bearing plate 11, both ends of the auxiliary lifting plate 4 are provided with slide grooves 5, a threaded rod 6 is rotatably connected inside one of the slide grooves 5, a fixed rod 19 is fixedly connected inside the other slide groove 5, a threaded block 16 is threadedly connected to the outer side of the threaded rod 6, a slider 18 is slidably connected to the outer side of the fixed rod 19, the tops of the slider 18 and the threaded block 16 are rotatably connected to a connecting rod 17, the auxiliary bearing plates 11 are rotatably connected to one end of the connecting rod 17 away from the threaded block 16 and the slider 18 respectively, the outer side of the auxiliary bearing plate 11 is fixedly connected to a bottom plate 12, and a lifting mechanism is arranged at the top of the base 1.

[0025] When it is necessary to assist in the disassembly of the civil defense door, the base 1 can be moved to the bottom end of the civil defense door. By rotating the threaded rod 6, the threaded block 16 can be driven to move in the slide groove 5. By cooperating with the fixed rod 19 and the slider 18, the auxiliary bearing plate 11 can be more stable during the rotation process and less prone to shaking, so that the angle of the auxiliary bearing plate 11 can be adjusted. By setting the lifting mechanism, the auxiliary lifting plate 4 can be lifted, so that the bottom plate 12 can support the bottom of the civil defense door. At this time, the staff can disassemble the civil defense door without the need for additional staff to assist. At the same time, during the laying down process, the auxiliary bearing plate 11 only needs to be laid flat for transportation, which saves time and effort.

[0026] Reference Figure 2 The lifting mechanism includes a telescopic cylinder 9 fixedly installed at the four corners of the top of the base 1, a horizontal plate 15 is fixedly connected between the piston rods of the two telescopic cylinders 9, the top ends of the piston rods of the telescopic cylinders 9 are fixedly connected to the bottom ends of the auxiliary lifting plate 4, and hydraulic cylinders 10 are fixedly installed at both ends of the top of the base 1, and the piston rods of the hydraulic cylinders 10 are fixedly connected to the corresponding horizontal plates 15.

[0027] By extending the piston rod of the hydraulic cylinder 10, the cross plate 15 can be pushed to move, and through the setting of the telescopic cylinder 9, the pressure borne by the auxiliary lifting plate 4 can be dispersed to the four telescopic cylinders 9, so that the auxiliary lifting plate 4 can be more stable during lifting. At the same time, the lifting setting of the auxiliary lifting plate 4 can be suitable for disassembly and use of civil defense doors of different heights.

[0028] Reference Figure 1 The four corners of the bottom of the base 1 are rotatably installed with directional wheels 2, and the top of the base 1 is fixedly connected with a push handle 3. Through the coordinated use of the directional wheels 2 and the push handle 3, the auxiliary tool for quick disassembly of the civil air defense door can be moved.

[0029] Reference Figure 1 , Figure 2 and Figure 3Slots 13 are provided at both ends of the auxiliary supporting plate 11, and snap-in plates 14 are snap-connected to the inside of the slots 13. By snapping the snap-in plates 14 into the corresponding slots 13, the two ends of the civil air defense door lying flat on the auxiliary supporting plate 11 can be limited to prevent the civil air defense door from sliding sideways during movement.

[0030] Reference Figure 1 A fixing groove 7 is opened inside the auxiliary lifting plate 4, and a servo motor 8 is fixedly installed inside the fixing groove 7. The output shaft of the servo motor 8 extends to the inside of the slide groove 5 and is fixedly connected to the threaded rod 6. The rotation of the output shaft of the servo motor 8 can drive the rotation of the threaded rod 6, thereby realizing the transmission of power.

[0031] Reference Figure 1 The servo motor 8 is electrically connected to an external control device, and the start and stop of the servo motor 8 can be controlled by the external control device.

[0032] Working principle: When it is necessary to assist in the disassembly of the civil air defense door, the base 1 can be moved to the bottom end of the civil air defense door, and then the servo motor 8 can be started to drive the rotation of the threaded rod 6, which can drive the threaded block 16 to move in the slide groove 5, and through the coordinated use of the fixed rod 19 and the slider 18, the auxiliary bearing plate 11 can be made more stable during the rotation process and not prone to shaking, so that the angle of the auxiliary bearing plate 11 can be adjusted, and the hydraulic cylinder 10 can be started to push the cross plate 15 to move, and through the setting of the telescopic cylinder 9, the pressure carried by the auxiliary lifting plate 4 can be adjusted. The force is dispersed to the four telescopic cylinders 9, so that the auxiliary lifting plate 4 can be more stable during lifting, so that the bottom plate 12 can support the bottom of the civil air defense door. At this time, the staff can dismantle the civil air defense door without the need for additional staff to assist. At the same time, during the laying down process, it is only necessary to lay the auxiliary supporting plate 11 flat for transportation, which saves time and effort. Then the clamping plate 14 is clamped in the corresponding slot 13, which can limit the two ends of the civil air defense door lying flat on the auxiliary supporting plate 11 to prevent the civil air defense door from slipping sideways during movement.

[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
