Description

Technical Field

[0001] The utility model relates to the technical field of escape device equipment, in particular to a safety emergency escape device. Background Art

[0002] With the dense population and the development of the construction industry, there are more and more high-rise buildings for people to live, work, etc. When a fire or other dangerous situation occurs in a high-rise building, it takes a long time for people to escape from the stairs. In the case of smoke and urgent time, it is very dangerous to use this method to escape, and the existing fire-fighting facilities cannot quickly and effectively extinguish the fire and rescue the high-rise buildings. Therefore, it is a more feasible way to escape directly from the outdoor of the high-rise building. When the current escape device is used at a high place, the rope drum is thrown down from a high place, and the rope drum directly hits the ground, which is easy to break and difficult to reuse, and may cause danger.

[0003] For example, in the Chinese patent literature, the publication number is CN114344745B, the publication date is November 29, 2022, and the name is an emergency safety escape descender, including: a speed limiter; a safety hook, the safety hook is arranged on the top of the speed limiter; a rope; a rope drum; a protective component; a connecting piece, the rope is connected to the connecting piece through the speed limiter; a safety belt, the safety belt is connected to the rope; and a buckle, the controller controls the air pump to work, so that the inflation tube inflates the annular airbag, and then the annular airbag, the support foot airbag and the horizontal airbag are inflated and filled. When they touch the ground, the annular airbag and the support foot airbag can effectively play a buffering effect to avoid injuring others and damaging the rope drum body. By supporting and unfolding the horizontal airbag, the final distance of the rope drum body falling can be reduced.

[0004] The prior art with publication number CN114344745B still has shortcomings. When using the escape descender, the rope drum containing the rope still needs to be thrown down from a high place. As the rope drum is thrown down from a high place, its acceleration becomes faster and faster. Even if an annular airbag is added to have a cushioning effect when landing, it is easy to break and difficult to reuse, and it may also injure others and cause danger. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a safety emergency escape device, which does not require the rope reel to be thrown down from a height during use, thereby avoiding damage to the rope reel and injuries to others, and avoiding the occurrence of danger.

[0006] The utility model is realized by the following scheme:

[0007] A safety emergency escape device, characterized in that it includes a supporting platform, a deceleration device and a rope, a fixed leg for fixing the escape device is arranged at the lower end of the supporting platform, the deceleration device is fixed to the fixed leg by a connecting strip, the rope is wound in the deceleration device, a first rope through hole and a second rope through hole are provided on the side of the deceleration device, one end of the rope passes through the first rope through hole from the deceleration device and is connected to a safety protection device, the other end of the rope passes through the second rope through hole from the deceleration device and is connected to an anti-falling device, when in use, the user wears the safety protection device to descend, and the end of the rope on which the anti-falling device is installed rises accordingly.

[0008] Furthermore, guardrails are arranged on both sides of the top of the support platform. When the user is ready to slowly descend, he or she grabs the guardrails on the support platform, so that the user has a support point when jumping outward through the guardrails on the support platform.

[0009] Furthermore, the deceleration device comprises a housing, a speed limiter and a rope drum, wherein the speed limiter and the rope drum are both assembled in the housing, and the speed limiter is connected to the rope drum shaft for controlling the rotation speed of the rope drum.

[0010] Furthermore, it includes a first fixed pulley, a second fixed pulley, a third fixed pulley and a fourth fixed pulley, the first fixed pulley and the second fixed pulley are assembled on the side of the lower end of the support platform close to the reduction device through a fixed shaft, the third fixed pulley and the fourth fixed pulley are assembled on the side of the lower end of the support platform away from the reduction device through a fixed shaft, and the two fixed shafts are parallel to each other, one end of the rope passing through the first rope hole is sequentially embedded in the grooves of the first fixed pulley and the third fixed pulley, and the other end of the rope passing through the second rope hole is sequentially embedded in the grooves of the second fixed pulley and the fourth fixed pulley.

[0011] Furthermore, the grooves of the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley are all provided with damping plates, and when the rope moves vertically, a large friction force is generated between the damping plates and the fixed pulleys to slow down the descent speed of the rope, thereby ensuring that the user will not be injured due to a large force when landing due to the rope descending too fast.

[0012] Furthermore, the safety protection device includes a safety belt and an anti-drop buckle, one end of the anti-drop buckle is fixedly connected to one end of the rope, and the other end is fixedly connected to the safety belt.

[0013] Furthermore, the safety belt is movably connected to a buckle for tightening or tightening the safety belt, and the buckle can be moved on the safety belt to adjust the tightness, so that the safety belt is firmly put on the user.

[0014] Furthermore, the lower end of the support platform is fixedly connected to an anti-slip pad.

[0015] Furthermore, a supporting crossbeam is installed between the fixed legs on both sides of the lower end of the supporting platform to increase the stability of the entire escape device.

[0016] The working principle of the utility model is as follows:

[0017] When in use, the escape device is fixed, the user puts on a safety belt, and after passing through the buckle hoop, grabs the guardrail on the supporting platform as a support point for jumping down. When the user falls, the vertical movement of the rope causes the rope drum to rotate. The rotation speed of the rope drum is controlled by connecting it to the rope drum through a speed limiter, thereby limiting the speed of the vertical movement of the rope, allowing the user to land safely on the bottom surface.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. In the utility model, the deceleration device integrates the rope drum and the speed limiter together. The integrated design does not require the rope drum to be dropped from a height during use, thereby avoiding damage to the rope drum and avoiding danger.

[0020] 2. In the utility model, damping plates are provided in the grooves of the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley. When the rope moves vertically, a large friction force is generated between the damping plates and the fixed pulleys to slow down the descent speed of the rope. At the same time, under the restriction of the speed limiter, the speed of the rope is further reduced, ensuring that the user will not be injured due to the large force when landing due to the excessive descent speed of the rope.

[0021] 3. In the utility model, guardrails are arranged on both sides of the top of the support platform. When the user is ready to slowly descend, he or she can hold the guardrails on the support platform with his or her hands, so that the user has a support point when jumping outward through the guardrails on the support platform, thereby alleviating the user's fear when hanging in the air.

[0022] 4. In the present invention, a supporting crossbeam is installed between the fixed legs on both sides of the lower end of the supporting platform to increase the stability of the entire escape device. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed leg 3 for fixing the escape device is arranged at the lower end of the supporting platform 1. The deceleration device 5 is fixed on the fixed leg 3 through a connecting strip 4. The rope 6 is wound in the deceleration device 5. A first rope through hole 8 and a second rope through hole 9 are provided on the side of the deceleration device 5. One end of the rope 6 passes through the first rope through hole 8 from the deceleration device 5 and is connected to the safety protection device. The other end of the rope 6 passes through the second rope through hole 9 from the deceleration device 5 and is connected to the anti-falling device 7. In the use state, the user wears the safety protection device to descend, and the end of the rope 6 equipped with the anti-falling device 7 rises accordingly.

[0030] The deceleration device 5 comprises a housing, a speed limiter and a rope drum. The speed limiter and the rope drum are both assembled in the housing. The speed limiter is connected to the rope drum shaft to control the rotation speed of the rope drum.

[0031] When in use, the escape device is fixed, the user puts on the safety protection device and tightens it, and then grabs the guardrail 2 on the support platform 1 as a support point for jumping down. When the user falls, the vertical movement of the rope 6 causes the rope drum to rotate, and the speed limiter is connected to the rope drum to control the rotation speed of the rope drum, thereby limiting the speed of the vertical movement of the rope 6, so that the user can safely fall on the bottom surface. During use, the rope drum does not need to be thrown down from a high place, which avoids damage to the rope drum and avoids the occurrence of danger.
