Description

Technical Field

[0001] This application relates to the technical field of descenders, and particularly to a high-rise building fire-fighting descender device. Background Art

[0002] With the continuous increase of high-rise buildings in cities, the fire safety problems of high-rise buildings have become increasingly prominent. The existing high-rise rescue methods mainly include fire ladders and helicopter rescues. However, limited by the height of the ladders and the takeoff and landing conditions of helicopters, these methods are not applicable in some cases.

[0003] Currently, there are some high-rise building descender devices on the market. These devices usually combine ropes and descenders to achieve the slow descent of personnel. During the descent process, personnel need to adjust the distance between themselves and the wall by pedaling, so as to ensure the smooth progress of the descent.

[0004] However, the method of personnel adjusting the distance between themselves and the wall by pedaling will cause the rope to swing significantly, and it takes a certain amount of time for personnel to pedal out to maintain the distance from the wall. Therefore, these devices have deficiencies in terms of operation safety and descent time control, affecting the rescue efficiency and personnel safety. Utility Model Content

[0005] In order to ensure that there is a certain distance between personnel and the wall during the descent of personnel, thereby improving the rescue efficiency, this application provides a high-rise building fire-fighting descender device.

[0006] The high-rise building fire-fighting descender device provided by this application adopts the following technical solutions:

[0007] A high-rise building fire-fighting descender device includes a protective box, which is detachably and fixedly connected to the wall. On one side of the protective box close to the wall, there is a bearing plate fixedly connected. Both ends of the bearing plate are fixedly connected with slide rails. Slide blocks are slidably connected in the slide rails. A connecting rod is provided on the slide block. There is a support block in the protective box. One end of the connecting rod is hinged to the slide block, and the other end is hinged to the support block. On one side of the bearing plate close to the slide rail, there are driving members. One end of the driving member is fixedly connected to the bearing plate, and the other end extends into the slide rail and is fixedly connected to the slide block. On the side of the protective box away from the wall, there is a rope-throwing port. A safety rope is provided in the protective box. One end of the safety rope passes through the protective box and is fixedly connected to the wall, and the other end is placed in the protective box and is lapped on the support block.

[0008] By adopting the above technical solution, when the driving member drives the slider to approach the receiving plate, under the action of the connecting rod, the support block extends out of the throwing rope opening. One end of the safety rope is fixed to the wall, and the other end extends to the ground under the action of gravity when the support block extends out of the throwing rope opening. At this time, the safety rope is lapped on the support block, ensuring that there is a certain distance between the person and the wall when using the descent device to slide down, thereby improving the rescue efficiency.

[0009] Optionally, a push plate is fixedly connected to the end of the support block away from the receiving plate.

[0010] By adopting the above technical solution, when the support block extends out of the throwing rope opening, the safety rope may shake due to the wind at high altitudes or when the support block pushes the safety rope out of the throwing rope opening. The push plate increases the shaking range of the safety rope, thereby further optimizing the safety of the descent device.

[0011] Optionally, a rounded corner structure is provided on the side of the push plate away from the receiving plate and close to the top of the protective box.

[0012] By adopting the above technical solution, when the person descends, there is a certain amount of shaking, and the safety rope will be worn due to the shaking between the safety rope and the push plate. The right angle edge may cause the safety rope to break. The rounded corner structure can reduce the degree of wear of the safety rope due to shaking, thereby increasing the service life of the safety rope.

[0013] Optionally, a plurality of reinforcing rib plates are fixedly connected between the push plate and the support block.

[0014] By adopting the above technical solution, when the push plate extends out of the throwing rope opening driven by the support block, since the torque between the push plate and the support block increases when the person descends, the possibility of fracture between the support block and the push plate increases. With a plurality of reinforcing rib plates, the strength between the push plate and the support block is improved, further improving the safety of the descent device.

[0015] Optionally, baffles are fixedly connected to both ends of the side of the push plate away from the wall.

[0016] By adopting the above technical solution, when the person descends, due to the instability of the center, the safety rope may shake greatly and is likely to slip off the push plate when shaking. By the baffles fixedly connected to both sides of the push plate, the possibility of the safety rope slipping off the push plate is reduced.

[0017] Optionally, the protective box is provided with a protective cover and has an L-shaped cross-section. A plurality of guide posts are fixedly connected to the side of the protective cover close to the protective box. Guide holes corresponding to the guide posts one by one are opened on the protective box, and the guide posts are inserted and matched with the guide holes.

[0018] By adopting the above technical solution, when the slow-down device is not needed, the support block is retracted in the protective box, and the cooperation between the guide column and the guide hole reduces the possibility of the protective cover falling off the protective box when the protective cover is placed on the protective box. The protective cover also further protects the internal structure of the slow-down device.

[0019] Optionally, a placement cavity is formed between a side of the push plate away from the wall and the protective cover, and the placement cavity is for placing the safety rope.

[0020] By adopting the above technical solution, since the slow-descending device is used at high floors, a very long safety rope is required, and the placement cavity formed between the push plate and the protective cover can place the safety rope, and when the slow-descending device is used, the safety rope in the placement cavity can be pushed out of the rope throwing port under the action of the push plate, thereby improving the rescue efficiency.

[0021] Optionally, a connector is provided on the slide rail, and a plurality of first sockets and second sockets are provided on the slide rail. When the support block extends out of the protective box, the connector cooperates with the second sockets, and when the support block is retracted into the protective box, the connector cooperates with the first sockets.

[0022] By adopting the above technical solution, the connector is respectively plugged into the first plug hole and the second plug hole, so that when the support block is extended or retracted, the slider is fixed on the slide rail, thereby ensuring the stability of the slow-descent device. When the support block is extended, a triangular structure is formed between the support block, the receiving plate and the slider, thereby further improving the stability of the slow-descent device when in use.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the driving member drives the slider to approach the receiving plate, the supporting block is extended out of the rope throwing port under the action of the connecting rod, and one end of the safety rope is fixed on the wall, and the other end is extended to the ground under the action of gravity when the supporting block extends out of the rope throwing port. At this time, the safety rope is overlapped on the supporting block, ensuring that there is a certain distance between the personnel and the wall when sliding down using the slow-down device, thereby improving the rescue efficiency;

[0025] 2. Since the descending device is used at high-rise buildings, a long safety rope is required. The placement cavity formed between the push plate and the protective cover can be used to place the safety rope. When the descending device is used, the safety rope in the placement cavity can be pushed out of the rope throwing port under the action of the push plate, thereby improving the rescue efficiency.

[0026] 3. The connectors are respectively inserted and fitted into the first jack and the second jack, so that when the support block extends or retracts, the slider is fixed on the slide rail, thus ensuring the stability of the slow descent device. And when the support block extends, a triangular cross-section structure is formed among the support block, the bearing plate and the slider, further improving the stability of the slow descent device during use.

Detailed Description of the Embodiment

[0034] The following further describes the present application in detail Figures 1-6 with reference to the accompanying drawings.

[0035] The embodiment of the present application discloses a slow descent device for high-rise building fire fighting.

[0036] Refer to Figures 1 to 3, A speed reduction device for high-rise building fire protection, including a protective box 1. The protective box 1 is detachably and fixedly connected to the wall 01 through climbing spikes and nuts. A bearing plate 2 is fixedly connected inside the protective box 1. Slide rails 21 are fixedly connected to both ends of the bearing plate 2. Blind holes are provided on one side of the bearing plate 2 close to the slide rails 21. A slider 213 is provided on the slide rail 21 and is slidably connected inside the slide rail 21. A driving member 22 is provided in the through hole. The driving member 22 is a spring. One end of the spring is fixedly connected in the blind hole, and the other end extends into the slide rail 21 and is fixedly connected to the slider 213. A throwing rope port 6 is provided on one side of the protective box 1 away from the wall 01. A support block 4 is provided inside the protective box 1. A connecting rod 3 is provided on the slider 213. One end of the connecting rod 3 is hinged to the slider 213, and the other end is hinged to the support block 4. A safety rope 8 is provided inside the protective box 1. One end of the safety rope 8 passes through the protective box 1, and the other end is coiled inside the protective box 1 and is lapped on the support block 4.

[0037] Refer to Figures 1 to 3 , When installing the speed reduction device, first, the installer drills a plurality of holes in the wall 01, and then inserts the climbing spikes into the holes, and the holes and the climbing spikes are in interference fit. The protective box 1 is provided with holes corresponding to the climbing spikes one by one. Then, the protective box 1 is placed on the climbing spikes, and the protective box 1 is fixed by nuts, so that the protective box 1 is fixedly installed on the wall 01. When the speed reduction device needs to be used, the spring drives the sliders 213 in the slide rails 21 at both ends of the bearing plate 2 to approach itself, so that the connecting rods 3 hinged on the sliders 213 approach the bearing plate 2, and the other ends of the connecting plates are hinged to the support block 4. When the two connecting rods 3 approach each other, under the action of the connecting rods 3, the support block 4 extends out of the throwing rope port 6. When the support block 4 extends out of the throwing rope port 6, the other end of the safety rope 8 is also pushed out of the protective box 1 and extends to the ground under the action of gravity. At this time, the safety rope 8 is lapped on the support block 4. When a person uses the speed reduction device to descend, due to the extension of the support block 4 and the safety rope 8 being lapped on the support block 4, there is a certain distance between the safety rope 8 and the wall 01, thus improving the rescue efficiency.

[0038] Refer to Figure 2 and Figure 4 , A push plate 42 is provided on the side of the support block 4 away from the wall 01, and the push plate 42 is fixedly connected to the support block 4. A plurality of reinforcing rib plates 41 are fixedly connected between the support block 4 and the push plate 42. Baffles 43 are provided at both ends of the side of the push plate 42 away from the wall 01, and the baffles 43 are fixedly connected to the push plate 42. A rounded corner structure 44 is provided on the push plate 42 close to the throwing rope port 6.

[0039] Refer to Figure 2 and Figure 4, when the driving member 22 drives the connecting rods 3 to approach each other, the support block 4 extends out of the throwing rope port 6. Since the push plate 42 is fixedly connected to the support block 4, when the support block 4 extends out, the push plate 42 also extends out together. At this time, the safety rope 8 is lapped on the push plate 42. Due to the wind on the high-rise building or when the push plate 42 pushes out the safety rope 8, the safety rope 8 is likely to shake, and the push plate 42 increases the shaking range of the safety rope 8. When a person uses the descent device, the force of the safety rope 8 and the weight of the user are completely pressed on the push plate 42, increasing the torque between the push plate 42 and the support block 4. Thus, the strength between the push plate 42 and the support block 4 is increased through the reinforcing rib plate 41, thereby improving the safety of the descent device. And at this time, since the user is on the safety rope 8 and due to the unstable center of gravity, baffles 43 are fixedly connected to both ends of the push plate 42 to prevent the user from falling off the push plate 42 due to unstable center of gravity and increasing the risk. During use, the safety rope 8 shakes due to the unstable center of gravity of the user. At this time, the abrasion between the safety rope 8 and the push plate 42 may lead to the possibility of the safety rope 8 breaking. Therefore, a rounded corner structure 44 is provided at the upper end of the side of the push plate 42 close to the throwing rope port 6, thereby reducing the risk of the safety rope 8 breaking due to abrasion and further improving the safety of the descent device.

[0040] Refer to Figure 4 and Figure 5 , a protective cover 7 is provided on the protective box 1, and the cross-section of the protective cover 7 is L-shaped. A plurality of guide holes 11 are provided on one side of the protective box 1 close to the protective cover 7, and guide posts 71 corresponding to the guide holes 11 one by one are fixedly connected to the protective cover 7. The guide posts 71 are inserted and matched with the guide holes 11. And a placement cavity 5 for placing the safety rope 8 is formed between the baffle 43 and the side of the protective cover 7 away from the wall 01.

[0041] Refer to Figure 4 and Figure 5 , when the support block 4 retracts into the protective box 1, the guide posts 71 on the protective cover 7 are inserted and matched in the guide holes 11 on the protective box 1, thereby protecting the internal structure of the descent device when the descent device is not in use. Since the descent device is used for high-rise buildings, the safety rope 8 needs to be relatively long, and the placement cavity 5 formed between the push plate 42 and the protective cover 7 can effectively coil the safety rope 8 in the placement cavity 5. When using the descent component, the safety rope 8 coiled in the placement cavity 5 is pushed out of the protective box 1 under the action of the push plate 42, thereby improving the rescue efficiency.

[0042] Refer to Figures 3 to 6, on both sides of the receiving plate 2, first jacks 211 and second jacks 212 are opened on the slide rails 21, and a plug-in member 23 is provided on the slide rail 21. The plug-in member 23 is a bolt. The bolt is inserted and matched with the jack. When the descending device is not in use, the bolts at both ends of the receiving plate 2 are inserted and matched in the first jacks 211. At this time, the support block 4 is in a state of being retracted into the protective box 1. When the descending component needs to be used, the bolts at both ends of the receiving plate 2 are pulled out from the first jacks 211. At this time, the slider 213 contracts under the spring force and quickly pulls the slider 213 towards one side of the receiving plate 2. When the slider 213 in the slide rail 21 slides close to the receiving plate 2, the bolt is inserted into the second jack 212. The cooperation between the bolt and the jack ensures the stability of the descending device.

[0043] The implementation principle of a descending device for high-rise building fire protection in an embodiment of the present application is as follows:

[0044] First, the installer drills a plurality of holes in the wall 01, and then inserts and matches the climbing rock nails in the holes, and the holes are in interference fit with the climbing rock nails. The protective box 1 is provided with holes corresponding to the climbing rock nails one by one. Then, the protective box 1 is placed on the climbing rock nails and fixed to the protective box 1 through nuts, so that the protective box 1 is fixedly installed on the wall 01.

[0045] When the descending device is not in use, the bolts are inserted and matched in the first jacks 211 of the slide rails 21 at both ends of the receiving plate 2. At this time, due to the insertion and matching of the bolt and the first jack 211, the slider 213 is fixed, and the spring is in a stretched state at this time. The support block 4 is also retracted into the protective box 1, and the safety rope 8 is also neatly coiled in the placement cavity 5 formed between the protective cover 7 and the push plate 42. At this time, the protective cover 7 is also inserted and matched in the protective box 1 through the guide post 71, thus protecting the internal structure of the descending device.

[0046] When the descending device needs to be used, the protective cover 7 is removed from the protective box 1 through the handle, and then the bolt inserted and matched in the first jack 211 is pulled out. At this time, under the action of the spring contraction, the slider 213 in the slide rail 21 slides along the slide rail 21 towards the receiving plate 2. Then, the bolt is inserted and matched in the second jack 212, so that the slider 213 is fixed in the slide rail 21.

[0047] At this time, due to the action of the spring, the slider 213 quickly moves towards the receiving plate 2. One end of the connecting plate is hinged to the slider 213, and the other end is hinged to the support block 4, causing the support block 4 to extend out of the throwing rope port 6, thus ensuring a certain distance between the personnel and the wall 01 and improving the rescue efficiency. The safety rope 8 coiled in the placement cavity 5 is pushed out of the protective box 1 while the support block 4 extends, and extends to the ground under the influence of gravity. At this time, a triangular cross-section structure is formed among the support block 4, the receiving plate 2, and the slider 213, further improving the stability of the descent device during use.

[0048] When the safety rope 8 is pushed out of the throwing rope port 6 and the user descends through the safety rope 8, due to the unstable center of gravity, it is easy to shake. Therefore, baffles 43 are fixedly connected to both ends of the push plate 42, further improving the safety of the descent device.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
