Description

Technical Field

[0001] The present application relates to the technical field of temporary support for construction anti-collapse, and in particular to an anti-collapse device for civil air defense projects. Background Art

[0002] As a special facility that guarantees the important functions of sheltering personnel and materials, civil air defense command, and medical rescue in wartime, the structural safety of civil air defense projects is of vital importance. During the construction of civil air defense projects, the complexity of geological conditions and unexpected conditions that may occur during the construction process, such as changes in groundwater levels, the existence of rock crushing zones, or construction accidents caused by improper operation, all pose a risk of causing the project structure to collapse. In addition, when encountering geological disasters such as earthquakes and mudslides, civil air defense projects are also facing the threat of collapse. Once a collapse occurs, it will cause serious damage to the lives and important facilities of the personnel in the project. Therefore, anti-collapse temporary support devices have become a key link in the safety guarantee system of civil air defense projects;

[0003] Chinese patent announcement number "CN220059609U" discloses an excavation anti-collapse device for water conservancy project construction. The device consists of a pad, an adjustment platform, a bidirectional screw, a screw slider, a lower rotating frame, a top support rod, a support block and a push-up mechanism. It drives the bidirectional screw to rotate by adjusting the winch, drives the screw slider to move, and then the top support rod pushes the push-up mechanism to realize the supporting function. The device adopts an arc-shaped structure design, which can be flexibly adjusted according to the height of the excavated civil air defense tunnel, and can fit closely to the inner wall of the civil air defense tunnel. It has the advantages of a wide bearing surface, multiple stress points, high structural strength and significant anti-collapse effect.

[0004] However, the existing device has obvious limitations when it is actually used in temporary support for anti-collapse of civil air defense projects. On the one hand, its lifting height mainly depends on the adjustment of a single top support rod. When facing a higher cavity of a civil air defense project, a longer top support rod needs to be set. Correspondingly, the length of the adjustment platform also needs to be greatly increased, and the length of the adjustment platform must be at least greater than the sum of the lengths of the two top support rods. For example, if a two-meter-high cavity is to be supported, a two-meter-long top support rod is required. At this time, the length of the adjustment platform must reach 4 meters or even longer. For scenes such as civil air defense projects that require high equipment mobility, such large equipment is extremely inconvenient to transport and carry or to install on site in temporary support applications. On the other hand, the anti-collapse tray on the top of the device lacks flexibility in design, which is neither convenient for disassembly nor difficult to further fold. This limits its application in complex civil air defense project environments to a certain extent. In summary, the existing anti-collapse device has many defects and shortcomings when applied to civil air defense projects, and it is urgent to carry out targeted improvement designs to better meet the actual needs of civil air defense projects and improve the safety and reliability of civil air defense projects.

[0033] The following is combined with Figure 1-11 This application is described in further detail.

[0034] The present application embodiment discloses a device for preventing collapse of civil air defense projects. Figure 1-11 As shown, it includes a rail frame 1, an adjusting mechanism 2 is fixedly installed in the middle of the inner side of the rail frame 1, driving mechanisms 5 are installed at both ends of the rail frame 1, the inner ends of the driving mechanisms 5 are connected to the adjusting mechanism 2, the top of the driving mechanism 5 located at the top of the two driving mechanisms 5 is fixedly installed with a supporting mechanism 3, and the bottom of the driving mechanism 5 located at the bottom of the two driving mechanisms 5 is fixedly installed with an anti-slip mechanism 4;

In the anti-collapse device of the air defense project, the rail frame 1 is an integral supporting structure, and the adjusting mechanism 2 in the middle of the inner side plays a core regulating role, the driving mechanisms 5 at both ends of the rail frame 1 are respectively connected to the adjusting mechanism 2, the top driving mechanism 5 is connected to the supporting mechanism 3, and the bottom driving mechanism 5 is connected to the anti-skid mechanism Structure 4. When the device needs to be used, the operator operates the adjustment component 25, and the adjustment component 25 drives the first bevel gear 22 connected to it to rotate inside the inner frame 21. Since the first bevel gear 22 is meshed with the second bevel gear 24 fixed to one end of the rotating shaft 23, the rotation of the first bevel gear 22 will drive the second bevel gear 24 to rotate, and then drive the rotating shaft 23 to rotate. After the rotating shaft 23 rotates, it will transmit power to the driving mechanism 5 connected to it, so that the driving mechanism 5 at the top pushes the supporting mechanism 3 to move upward and contact with the top of the civil air defense project to be supported, thereby playing a supporting role; the driving mechanism 5 at the bottom pushes the anti-skid mechanism 4 to move downward, fits tightly with the ground, and plays an anti-skid role, thereby realizing the anti-collapse support of the civil air defense project by the entire device.

[0036] Please refer to Figure 1-Figure 5 and Figure 8The support mechanism 3 includes a top plate 31, which is fixedly installed on the top of the skateboard on the side of the rail frame 1 away from the bottom plate 42. Support components 34 are hingedly installed on both sides of the top plate 31. Connecting frames 33 are fixedly installed on both sides of the bottom of the top plate 31. The bottom of the connecting frame 33 is hinged with a supporting component 32. The support component 34 includes a support plate 341, which is hingedly installed on both sides of the top plate 31. The middle of the bottom of the support plate 341 is hinged to the top of the supporting component 32. A side rail 342 is fixedly installed on the outer side of the support plate 341. The inner side of the side rail 342 is slidably connected with a mounting plate 343. The outer side of the mounting plate 343 is fixedly connected with an anti-skid receiving plate 344. The outer side of the anti-skid receiving plate 344 is provided with anti-skid patterns 345 at equal intervals. The inner lower end of 341 is fixedly connected to a limiting group 346, and the limiting group 346 includes a fixing frame 3461 and a slot 3462. The fixing frame 3461 is fixedly connected to the inner lower end of the support plate 341. The inner side of the fixing frame 3461 is fixedly connected to a limiting spring 3463. The end of the limiting spring 3463 is fixedly connected to a movable block 3465. The movable block 3465 is slidably connected to the inside of the fixing frame 3461. The top of the movable block 3465 is fixedly connected to a block 3466. The slot 3462 is provided at the lower ends of the mounting plate 343 and the support plate 341. The outer side of the block 3466 passes through the slot 3462 of the support plate 341 and is inserted into the slot 3462 of the mounting plate 343. The block 3466 is fixed away from the side of the mounting plate 343. A connecting shaft 3467 is connected, and the end of the connecting shaft 3467 passes through the fixed frame 3461 and is fixedly connected to the twitching plate 3464. The supporting component 32 includes a sleeve frame 321, and the sleeve frame 321 is hinged to the bottom of the connecting frame 33. The interior of the sleeve frame 321 is slidably connected to the supporting plate 322, and the outer end of the supporting plate 322 is hinged to the linkage frame 323. The outer side of the linkage frame 323 is hinged to the middle of the bottom of the support plate 341. The outer upper end of the sleeve frame 321 is threadedly connected to a locking screw 324, and the end of the locking screw 324 passes through the sleeve frame 321. The outer side of the supporting plate 322 is linearly arranged at equal intervals and has card holes 325. The end of the locking screw 324 is inserted into the inside of the card hole 325. In the supporting mechanism 3 of the anti-collapse device of the air defense engineering, the top plate 31 The top of the slide plate installed in the rail frame 1 on the side away from the bottom plate 42 has the support plates 341 hinged on both sides that can rotate flexibly. When the device starts working, the adjustment mechanism 2 drives the slide plate to move, thereby pushing the top plate 31 up. In this process, the support component 32 plays a key role. The sleeve frame 321 of the support component 32 is hinged to the bottom of the connecting frame 33. By adjusting the expansion and contraction of the support plate 322 in the sleeve frame 321, the total length of the sleeve frame 321 and the support plate 322 can be changed. As the length changes, the linkage frame 323 supports and pushes the support plate 341 to rotate, so that the support plate 341 moves outward and fits the top of the civil air defense project. At the same time, the locking screw 324 at the upper end of the outer side of the sleeve frame 321 can be twisted to insert its end into the clamping hole 325 on the outer side of the support plate 322.The support assembly 32 is supported and reinforced to ensure that the tilting support angle of the support plate 341 is fixed and the support is stable. On the outside of the support plate 341, the anti-skid receiving plate 344 is slidably connected to the side rail 342 through the mounting plate 343. During installation, the limiting spring 3463 in the limiting group 346 pushes the movable block 3465, so that the block 3466 passes through the slot 3462 of the support plate 341 and is inserted into the slot 3462 of the mounting plate 343 to stabilize the mounting plate 343. If the anti-skid receiving plate 344 needs to be replaced, the plate 3464 is pulled to drive the connecting shaft 3467 to make the movable block 3465 squeeze the limiting spring 3463 and move inward, so that the block 3466 is separated from the slot 3462, and the mounting plate 343 can be pulled out for replacement to meet different support requirements.

[0037] Please refer to Figure 1-Figure 5 and Fig. 9 The adjusting assembly 25 includes a disc 251, which is fixedly installed in the middle of the front of the rail frame 1. The front of the disc 251 is rotatably connected to an adjusting plate 252, and the upper end of the front of the adjusting plate 252 is rotatably connected to an adjusting armrest 253. The back of the adjusting plate 252 is connected to the first bevel gear 22, and the lower end of the adjusting plate 252 is threadedly connected to a first screw rod 254. The front of the disc 251 is arranged in a ring shape with equal intervals to provide limiting holes 255. The end of the first screw rod 254 passes through the adjusting plate 252 and is inserted into the limiting hole 255. In the adjusting assembly 25 of the anti-collapse device of the civil air defense project, the disc 251 is fixedly installed in the middle of the front of the rail frame 1, becoming the basic component for the adjustment operation. When the device needs to be adjusted, the operator holds the adjusting armrest 253 and rotates the adjusting armrest 253 by applying force to drive the adjusting plate 252 rotatably connected thereto to rotate on the front of the disc 251. The first bevel gear 252 is engaged with the second bevel gear 24, and the second bevel gear 24 is engaged with the second bevel gear 24 to transfer power to the rotating shaft 23, thereby driving the subsequent components such as the driving mechanism 5 to move, thereby controlling the supporting mechanism 3 and the anti-skid mechanism 4. When adjusted to a suitable position, the first screw 254 at the lower end of the adjusting plate 252 is twisted so that its end passes through the adjusting plate 252 and is inserted into the limiting hole 255 arranged in a ring shape on the front side of the disc 251. The first screw 254 cooperates with the limiting hole 255 to play a role of limiting clamping, thereby fixing the position of the adjusting plate 252, ensuring that the first bevel gear 22 remains in the corresponding working state, so that the entire adjusting operation is completed and stabilized, and ensuring that the device can play an anti-collapse supporting role for the civil air defense project in a suitable state.

[0038] Please refer to Figure 1-Figure 5 and Figure 10-11The driving mechanism 5 includes a turntable 51, which is rotatably connected to the top and bottom of the inner frame 21. A screw rod 52 is fixedly connected to the outer side of the turntable 51. The inner side of the turntable 51 is connected to the two ends of the rotating shaft 23. The outer surface of the screw rod 52 is threadedly connected to a sliding rod 53. The screw rods 52 at both ends in the rail frame 1 have opposite thread rotation directions. The outer end of the sliding rod 53 at the top is connected to the supporting mechanism 3, and the outer end of the sliding rod 53 at the bottom is connected to the anti-skid mechanism 4. The anti-skid mechanism 4 includes an articulated seat 41. The articulated seat 41 is hingedly installed at the bottom of the sliding rod 53 at one end of the rail frame 1 away from the supporting mechanism 3. The bottom of the articulated seat 41 is fixedly installed with a bottom plate 42, anti-skid components 43 are provided at the four corners of the top of the bottom plate 42, and the four corners of the bottom plate 42 are all provided with through holes 44. The bottom of the anti-skid component 43 passes through the through holes 44. The anti-skid component 43 includes a frame 431, and the frame 431 is fixedly connected to the four corners of the top of the bottom plate 42. The internal thread of the frame 431 is connected with a threaded rod 432, and the top of the threaded rod 432 is fixedly connected with an adjustment handle 433, and the bottom of the threaded rod 432 is fixedly connected with an anti-skid cone 434. The bottom of the anti-skid cone 434 is inserted into the inside of the through hole 44. In the anti-collapse device of the civil air defense project, the driving mechanism 5 is used as a connection between the adjustment mechanism 2 and the support and anti-collapse mechanism 2. The key part of the sliding mechanism 4 is based on the coordinated operation of various components. When the rotating shaft 23 of the adjusting mechanism 2 rotates, the rotating disk 51 connected thereto is driven to rotate at the top and bottom of the inner frame 21. Since the screw rod 52 is fixedly connected to the outer side of the rotating disk 51, the rotation of the rotating disk 51 drives the screw rod 52 to rotate synchronously. It is worth noting that the screw rods 52 at both ends of the rail frame 1 have opposite thread rotation directions. When the screw rod 52 rotates, the sliding rod 53 threadedly connected thereto will move in the rail frame 1 along the direction of the screw rod 52. The outer end of the top sliding rod 53 is connected to the supporting mechanism 3, and the outer end of the bottom sliding rod 53 is connected to the anti-slip mechanism 4, so the movement of the sliding rod 53 will push The corresponding mechanism moves, taking the anti-skid mechanism 4 at the bottom as an example, when the sliding rod 53 moves downward, the hinged seat 41 and the base plate 42 connected thereto are driven to descend. At this time, the threaded rod 432 can be driven to rotate in the frame 431 by twisting the adjusting handle 433. Since the threaded rod 432 is threadedly connected to the frame 431, the rotating threaded rod 432 drives the anti-skid cone 434 to move downward, pass through the through hole 44 on the base plate 42 and insert into the ground. The anti-skid cone 434 is used to penetrate into the ground to enhance the friction between the device and the ground, play an anti-skid role, and prevent the device from being displaced during the support process, thereby providing a stable support foundation for civil air defense projects.

[0039] The implementation principle of the anti-collapse device for civil air defense engineering in the embodiment of the present application is as follows:

[0040] The device is provided with an adjustment mechanism 2, so that during use, the user can flexibly pull the adjustment plate 252 on the circular plate by holding the adjustment armrest 253, and the rotation of the adjustment plate 252 immediately drives the first bevel gear 22 to rotate synchronously. In this process, the first bevel gear 22 and the second bevel gear 24 are precisely meshed. As the first bevel gear 22 continues to rotate, the second bevel gear 24 is driven and starts to rotate. The rotation of the second bevel gear 24 drives the rotating shaft 23 connected thereto to operate synchronously. The rotation of the rotating shaft 23 can synchronously drive the two screw rods 52 to rotate at the same time. It is worth mentioning that the screw rods 52 at the top and bottom of the rail frame 1 are designed to have opposite thread rotation directions. Based on this, the screw rod 52 can drive the sliding rod 53 inside the rail frame 1 to slide smoothly on the inner side of the rail frame 1 when rotating. By driving the two sliding rods 53 to slide synchronously outward, the anti-skid mechanism 4 at the bottom and the supporting mechanism 3 at the top can be smoothly pushed to move in different directions respectively. The anti-skid mechanism 4 moves downward and fits tightly to the ground, effectively playing an anti-skid role. The support mechanism 3 moves upward until it contacts the top of the civil air defense tunnel or basement that needs to be supported, thereby achieving stable support. After the adjustment work is completed, it is only necessary to twist the first screw 254 on the adjustment plate 252 and insert it into the limiting hole 255. The first screw 254 and the limiting hole 255 are mutually limited and engaged, which can effectively fix the slide bar 53, ensure that the slide bar 53 remains stable in the extended state, provide reliable support for the device, and effectively avoid safety hazards such as collapse and collapse. In addition, during use, by adjusting the rotation of the screw rod 52, the slide bar 53 can be driven to move inward, so that the slide bar 53 is retracted to the two ends inside the rail frame 1, so as to realize the contraction function of the device. This telescopic design using two screw rods 52 to cooperate with the slide bar 53 greatly improves the telescopic utilization rate. Taking the support requirement of two meters in height as an example, the device can be maintained at a state of about one meter after contraction. Compared with the existing technical means, it can be folded more efficiently, and the device is small in size, easy to carry and operate flexibly, which significantly improves the convenience and flexibility of its application.

[0041] The device cooperates with the support mechanism 3 and the anti-skid mechanism 4 so that they can exert excellent performance and advantages through mutual cooperation in actual use. When the device is put into use, the bottom plate 42 is firstly placed on the ground. At this time, the adjusting handle 433 can be twisted, and the rotation of the adjusting handle 433 drives the threaded rod 432 to rotate accordingly. The rotation of the threaded rod 432 causes the anti-skid cone 434 to move downward and gradually insert into the soil on the ground. As the threaded rod 432 continues to rotate, the anti-skid cone 434 continues to penetrate into the soil, thereby playing a good anti-skid role. When carrying the device, by adjusting The handle 433 drives the threaded rod 432 to move upward, and the anti-skid cone 434 can be hidden inside the frame 431, which effectively avoids the risk of stabbing caused by the anti-skid cone 434 during carrying, greatly improving the safety and convenience of carrying. During use, the supporting plate 322 inside the sleeve frame 321 can be flexibly adjusted to slide, and the total length of the sleeve frame 321 and the supporting plate 322 can be extended by controlling the extension and contraction of the supporting plate 322 in the sleeve frame 321. As the total length of the sleeve frame 321 and the supporting plate 322 changes, the linkage frame 323 on the supporting assembly 32 can be prompted to support and push the top The support plates 341 on both sides of the plate 31 rotate, so that the support plates 341 move outward and fit tightly against the top of the civil air defense tunnel. By accurately adjusting the total length of the sleeve frame 321 and the supporting plate 322, not only can the inclination support angle of the support plate 341 be flexibly adjusted, but the support plate 341 can also be supported and strengthened, which significantly improves the overall stability of the device. After the adjustment work is completed, it is only necessary to twist the locking screw 324 and insert it into the inner side of the card hole 325 to support and reinforce the sleeve frame 321 and the supporting plate 322 of the entire supporting assembly 32, further ensuring that the device has good The support stability is improved. In addition, when the support adjustment is completed, the support plate 322 can be retracted into the inner side of the sleeve frame 321 by adjusting the loose locking screw 324. The contraction of the support plate 322 drives the support component 32 and the support component 34 to contract together. At this time, the support component 34 can be closed and stored on both sides of the rail frame 1, and the support component 32 can be hidden inside the connecting frame 33. This design allows the support mechanism 3 to be flexibly stored, and cooperates with the telescopic design of the slide rod 53, which greatly enhances the folding function of the device, further improves the overall portability, and provides great convenience for practical applications.

[0042] The device is provided with a support assembly 34, so that it exhibits excellent adaptability and convenience during use. When in use, the mounting plate 343 is inserted into the side rail 342. After the mounting plate 343 is inserted, the limit spring 3463 is reset to push the movable block 3465 to move. The movement of the movable block 3465 drives the clamping block 3466 to pass through the clamping slot 3462 on the side rail 342 and insert into the clamping slot 3462 of the mounting plate 343. Through the mutual clamping and limiting of the clamping block 3466 and the clamping slot 3462, the mounting plate 343 can be stably mounted on the side rail 342. 42, after the installation of the mounting plate 343 is completed, the anti-skid receiving plate 344 is installed on the outside of the supporting plate 341. When the supporting mechanism 3 of the device is fully unfolded, the driving mechanism 5 is driven by the adjusting mechanism 2 to push the supporting plate 341 to move upward. The upward movement of the supporting plate 341 pushes the anti-skid receiving plate 344 to move upward synchronously until the anti-skid receiving plate 344 contacts the top of the civil air defense tunnel that needs to be supported. By adjusting the two anti-skid receiving plates 344 to unfold, and the anti-skid patterns 345 with equal intervals on the outside of the anti-skid receiving plates 344, the supporting effect can be effectively enhanced. During the process, the top uses the anti-skid receiving plate 344 and the anti-skid pattern 345 for anti-skid, and the bottom uses the threaded rod 432 for threaded anti-skid, so that the device as a whole has a strong supporting strength. If it is necessary to replace the anti-skid receiving plate 344 of a different shape during use, the connecting shaft 3467 can be pulled by adjusting the pulling plate 3464 to drive the movable block 3465 to squeeze the limit spring 3463 to compress it and move it inward. At this time, the block 3466 can be separated from the slot 3462, so that the mounting plate 343 can be smoothly pulled out from the inside of the side rail 342, so that different shapes can be replaced conveniently and quickly. The anti-skid receiving plate 344 of the shape significantly improves the adaptability of the device. In addition, the anti-skid mechanism 4 at the bottom of the device is provided with a hinge seat 41. Based on the design of the hinge seat 41, the device can be flexibly adjusted to be tilted according to actual needs, which is convenient for precise adjustment of the support angle. The support design of the bottom threaded rod 432 and the top anti-skid receiving plate 344 cooperate with each other. Coupled with the telescopic and adjustable characteristics of the device, it can support and reinforce more efficiently, and can better adapt to the support and use requirements in different civil air defense engineering tunnels, which comprehensively improves the overall adaptability and use performance of the device.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
