Description

Technical Field

[0001] This invention relates to the field of high-rise escape technology, and in particular to a high-rise escape device with an escape mechanism. Background Technology

[0002] In high-rise buildings, fire safety and emergency escape are paramount. While traditional elevator escape routes are fast, they may fail in emergencies such as fires due to power outages or malfunctions, and their evacuation speed is limited. In contrast, stairwells offer a more reliable escape route, but their speed is relatively slower.

[0003] Escape mechanisms are widely used in watches and mechanical devices. Their characteristics enable the stable transmission of power and precise speed control, which is crucial for complex mechanical systems. Introducing the concept of escape mechanisms into high-rise escape devices can provide a more stable and reliable power transmission method, contributing to improved escape efficiency and safety.

[0004] Existing high-rise escape devices often suffer from problems such as difficulty in controlling descent speed and the risk of falling too quickly; manual retrieval of steel wire ropes is laborious and inconvenient to operate in emergencies; some devices are not securely fixed and cannot operate after a power outage, and their loose structure makes it difficult to guarantee escape safety and efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing high-rise escape steel wire ropes lack a precise speed control mechanism, and to propose a high-rise escape device with an escape mechanism.

[0006] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0008] The roller shaft is fitted with a concentrically fixed roller, and a pair of symmetrically distributed baffles are fitted at the front and rear ends of the roller. The outer surface of the roller is fixed with a spirally wound and evenly distributed steel wire rope, and the bottom end of the steel wire rope is fixed with a U-shaped buckle.

[0009] The bottom end of the L-shaped vertical plate is rotatably inserted with a through-distributed fixed shaft, the front end of the fixed shaft is fitted with a concentrically fixed escape ratchet, and the lower middle part of the front of the L-shaped vertical plate is rotatably inserted with an escape shaft, which is connected to the fixed shaft through an escape mechanism.

[0010] An L-shaped bracket is fixedly installed on the upper center of the front of the L-shaped vertical plate. A square through hole is opened on the L-shaped bracket. A motor with the output end facing backward is fixedly installed inside the square through hole. The motor is connected to the roller shaft through a drive mechanism.

[0011] Preferably, a small-diameter fixed gear is fitted at the rear end of the fixed shaft and is concentrically fixed. A linkage shaft is rotatably inserted into the lower middle part of the back of the L-shaped vertical plate. A large-diameter linkage gear is fitted at the rear end of the linkage shaft and is concentrically fixed. The large-diameter linkage gear meshes with the small-diameter fixed gear.

[0012] Preferably, a small-diameter linkage gear is concentrically fixed to the middle of the linkage shaft, and a large-diameter fixed gear is concentrically fixed to the roller shaft, wherein the large-diameter fixed gear meshes with the small-diameter linkage gear.

[0013] Preferably, the escapement mechanism includes a fixed sleeve and an escape lever. The escapement shaft is fitted with a fixed sleeve that is concentrically fixed. The rear end of the fixed sleeve is fixed with a pair of symmetrically distributed escape levers, and the pair of escape levers alternately engage with the escape ratchet.

[0014] Preferably, the front end of the fixed sleeve is fixedly provided with a T-shaped lifting ring that is vertically distributed downwards, and the bottom end of the T-shaped lifting ring is fixedly inserted with a counterweight connecting block.

[0015] Preferably, the drive mechanism includes a turntable, a one-way disc, and a sliding disc. The turntable is concentrically fixed to the middle of the motor shaft of the motor. The one-way disc is fixed to the front end of the roller shaft. A cross groove is opened on the outer side of the one-way disc. The sliding disc is slidably inserted inside the cross groove. The sliding disc is connected to the turntable through a limiting component. The end of the motor shaft of the motor is slidably inserted in the middle of the sliding disc.

[0016] Preferably, the limiting component includes a sliding block and a triangular block. Four evenly distributed sliding blocks are fixed on the outer side of the sliding disk. The four sliding blocks are slidably inserted into the four ends of the cross groove. Four evenly distributed triangular blocks are fixed on the outer side of the turntable. Each triangular block is in sliding contact with the corresponding sliding block.

[0017] Preferably, a plurality of tension springs are fixedly installed inside the cross groove, and the outer end of each tension spring is fixedly connected to the sliding disc.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the escape ratchet and escape lever engage alternately, changing continuous rotation to intermittent rotation, effectively controlling the descent speed and preventing the escapee from falling too quickly. The gear transmission adjusts the speed through diameter difference, and the baffle prevents the wire rope from slipping off. Multiple structures ensure a smooth and safe descent process.

[0022] 2. In this invention, the motor serves as the power source, driving the roller to rotate in the opposite direction via a drive mechanism, thereby achieving automatic wire rope recovery without manual operation. The U-shaped buckle facilitates connection to the safety belt, and the device can be used immediately after installation, enabling rapid deployment for escape in emergencies.

[0023] 3. In this invention, the flange is securely fixed with expansion bolts, and the L-shaped vertical plate and L-shaped connecting plate provide reliable support. The layout of each component is compact. Battery power ensures that the motor can still work when the power is off, and the overall structure balances stability and practicality.

[0024] In summary, this invention ensures safety through an escape mechanism and gear transmission, improves operational efficiency through a motor and convenient connectors, and enhances reliability through a robust structure and emergency power supply design, providing a safe and efficient solution for high-rise escape.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Example: This example provides a high-rise escape device with an escape mechanism. See [link to example]. Figures 1 to 6 Specifically, it includes a flange 100, on the bottom surface of which are provided several evenly distributed flange holes. An expansion bolt 101 is inserted into the interior of each flange hole. The flange 100 serves as the basic installation structure of the entire device. Through the flange holes on the bottom surface and the expansion bolts 101, it achieves a stable connection with the top wall of the high-rise building, providing load-bearing support for the device. The front end of the flange 100 is fixed with a downwardly vertically distributed L-shaped vertical plate 200, and the rear end of the flange 100 is fixed with a downwardly vertically distributed L-shaped connecting plate 103. A roller 104 is rotatably inserted into the bottom end of the L-shaped connecting plate 103. The front end of the roller 104 is rotatably inserted through the L-shaped vertical plate 200. The roller 104 serves as the mounting shaft for the roller 105, the large-diameter fixed gear 207, and the one-way disc 308, realizing torque transmission and rotational support.

[0035] A concentrically fixed roller 105 is fitted on the roller shaft 104. A pair of symmetrically distributed baffles 106 are fitted on the front and rear ends of the roller 105. A spirally wound and evenly distributed steel wire rope 107 is fixed on the outer surface of the roller 105. A U-shaped buckle 108 is fixed at the bottom end of the steel wire rope 107. The steel wire rope 107 is connected to the safety belt of the escapee through the U-shaped buckle 108. It is the core traction component that bears the weight of the escapee and realizes vertical descent.

[0036] The bottom end of the L-shaped vertical plate 200 is rotatably inserted with a through-type fixed shaft 201. The front end of the fixed shaft 201 is fitted with a concentrically fixed escape ratchet 202. The lower middle part of the front of the L-shaped vertical plate 200 is rotatably inserted with an escape shaft 300. The escape shaft 300 is connected to the fixed shaft 201 through an escape mechanism. The escape ratchet 202, through alternating engagement with the escape lever 302, converts continuous rotation into intermittent rotation, thereby controlling the descent speed.

[0037] An L-shaped bracket 313 is fixedly installed on the upper center of the front of the L-shaped vertical plate 200. A square through hole is opened on the L-shaped bracket 313. A motor 305 with the output end facing backward is fixedly installed inside the square through hole. The motor 305 is connected to the roller 104 through a drive mechanism. The motor 305 serves as the power source when the wire rope 107 is retracted. The motor 305 drives the roller 104 to rotate in the opposite direction through the drive mechanism.

[0038] In the specific implementation process, such as Figure 4 and Figure 5 As shown, a small-diameter fixed gear 203 is concentrically fixed at the rear end of the fixed shaft 201, and a linkage shaft 204 is rotatably inserted into the lower middle part of the back of the L-shaped vertical plate 200. A large-diameter linkage gear 206 is concentrically fixed at the rear end of the linkage shaft 204. The large-diameter linkage gear 206 meshes with the small-diameter fixed gear 203 to realize the torque transmission between the fixed shaft 201 and the linkage shaft 204, and adjust the speed by the difference in gear diameter.

[0039] A small-diameter linkage gear 205 is concentrically fixed in the middle of the linkage shaft 204, and a large-diameter fixed gear 207 is concentrically fixed in the roller shaft 104. The large-diameter fixed gear 207 meshes with the small-diameter linkage gear 205 to transmit the rotation of the roller shaft 104 to the linkage shaft 204, and at the same time increases the rotation speed through the diameter difference.

[0040] The escapement mechanism includes a fixed sleeve 301 and an escape lever 302. The fixed sleeve 301 is concentrically fixed on the escape shaft 300. A pair of symmetrically distributed escape levers 302 are fixed at the rear end of the fixed sleeve 301. The pair of escape levers 302 are alternately engaged with the escape ratchet 202. The escape levers 302 alternately engage with the escape ratchet 202, causing the escape ratchet 202 to rotate intermittently, controlling the descent speed to ensure stability.

[0041] The front end of the fixed sleeve 301 is fixed with a T-shaped lifting ring 303 that is vertically distributed downwards. The bottom end of the T-shaped lifting ring 303 is fixedly inserted with a counterweight block 304. The T-shaped lifting ring 303 and the counterweight block 304 provide continuous pressure to the escape lever 302 through the counterweight gravity, ensuring that it is stably engaged with the escape ratchet 202.

[0042] In the specific implementation process, such as Figure 4 and Figure 6 As shown, the drive mechanism includes a turntable 306, a one-way disc 308, and a sliding disc 309. The turntable 306 is concentrically fixed to the middle of the motor shaft of the motor 305. The one-way disc 308 is fixed to the front end of the roller 104. A cross groove 310 is opened on the outer side of the one-way disc 308. The sliding disc 309 is slidably inserted inside the cross groove 310. The sliding disc 309 is connected to the turntable 306 through a limiting component. The end of the motor shaft of the motor 305 is slidably inserted in the middle of the sliding disc 309.

[0043] The limiting component includes a sliding stop 312 and a triangular stop 307. Four evenly distributed sliding stops 312 are fixed on the outer side of the sliding disk 309. The four sliding stops 312 are slidably inserted into the four ends of the cross groove 310. Four evenly distributed triangular stops 307 are fixed on the outer side of the turntable 306. Each triangular stop 307 is in sliding contact with the corresponding sliding stop 312. Through the cooperation of the sliding stops 312 and the triangular stops 307, the power transmission or separation is realized under the action of the tension spring 311, ensuring that the motor 305 does not interfere when descending and that the motor 305 is effectively driven when retracting.

[0044] Several tension springs 311 are fixed inside the cross groove 310. The outer end of each tension spring 311 is fixed to the sliding disk 309. The tension spring 311 provides outward tension to the sliding disk 309, ensuring that the sliding block 312 is in close contact with the triangular block 307 or resets.

[0045] A storage battery 102 is fixedly installed in the middle of the flange 100. A charging connector 109 is fixedly installed at the bottom end of the storage battery 102. A wire hole is opened in the upper middle part of the L-shaped vertical plate 200. A conductive wire 110 is inserted into the wire hole. The two ends of the conductive wire 110 are electrically connected to the storage battery 102 and the motor 305 respectively. The charging connector 109 is used to charge the storage battery 102 to ensure its power reserve.

[0046] The working principle of this embodiment is as follows: During the device installation stage, the flange 100 is first fixed to the top wall of the high-rise building using expansion bolts 101, thus building a stable installation foundation for the entire escape device and ensuring structural stability during subsequent use; When a fire or other emergency occurs in a high-rise building, the escapee must first wear the high-altitude safety belt correctly and securely lock the safety belt to the U-shaped buckle 108, and then can carry out the escape action through the window;

[0047] As the survivor begins to fall, the combined effect of their own weight and gravitational acceleration will pull the steel cable 107 downward, thereby causing the roller 105, a pair of baffles 106, roller shaft 104, large-diameter fixed gear 207, one-way disc 308 and sliding disc 309 to rotate synchronously.

[0048] At this time, under the tension of the tension spring 311, the sliding disk 309 and the sliding block 312 will slide outward along the cross groove 310. As the one-way disk 308 rotates, the sliding block 312 will slide along the slope of the triangular block 307, thereby driving the sliding disk 309 and the sliding block 312 to slide inward along the cross groove 310. This ensures that the one-way disk 308 can maintain the normal rotation direction.

[0049] Since the large-diameter fixed gear 207 meshes with the small-diameter linkage gear 205 sleeved in the middle of the linkage shaft 204, when the large-diameter fixed gear 207 rotates, it will drive the small-diameter linkage gear 205 to rotate accordingly, thereby driving the linkage shaft 204 and the large-diameter linkage gear 206 sleeved behind it to rotate at a moderate speed.

[0050] The large-diameter linkage gear 206 meshes with the small-diameter fixed gear 203 sleeved at the rear end of the fixed shaft 201. Under the meshing transmission action of the large-diameter linkage gear 206, the small-diameter fixed gear 203 will drive the fixed shaft 201 and the escape ratchet 202 sleeved at its front end to rotate at a high speed.

[0051] During this process, a pair of escape levers 302 will alternately engage with the escape ratchet 202, thereby causing the escape ratchet 202 to rotate intermittently, ultimately realizing the descent of the roller 104, roller 105 and wire rope 107, further ensuring the stability and safety of the escapee during the descent.

[0052] When the wire rope 107 needs to be recycled, the battery 102 will supply power to the motor 305 through the conductive wire 110, and the motor shaft of the motor 305 will drive the turntable 306 to rotate in the opposite direction.

[0053] Under the tension of the tension spring 311, the sliding disc 309 and the sliding stop 312 will slide outward along the cross groove 310. The sliding stop 312 will form a limiting effect with the triangular stop 307, thereby driving the sliding stop 312, the sliding disc 309, the one-way disc 308, the roller 104, the roller 105, the pair of stop discs 106, and the large-diameter fixed gear 207 to rotate, and driving the wire rope 107 to perform the winding operation.

[0054] Meanwhile, under the combined action of the large-diameter fixed gear 207, the small-diameter linkage gear 205, the linkage shaft 204, the large-diameter linkage gear 206, the small-diameter fixed gear 203, the fixed shaft 201, and the escape ratchet 202, a pair of escape levers 302 will alternately move the escape ratchet 202 intermittently.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
