[0002] At present, in order to ease the tension of urban land, the height of buildings is constantly increasing, and more and more medium and high-rise buildings are springing up. However, fire safety issues also come with it. When fires and other accidents occur in high-rise buildings, elevators cannot be used and the corridors are filled with thick, suffocating toxic smoke. Therefore, high-rise residents generally have difficulty escaping. This issue has received widespread attention and attention from the society.

[0003] At present, in order to facilitate high-rise residents to escape quickly in the event of a fire accident, a high-rise emergency escape device, also called a descender, has been invented. It is a safety rescue device that allows people to slowly descend along a rope. It can be installed in the window, balcony or flat roof of a building through a special installation device. In the event of a fire, high-rise residents can use the escape device to slowly descend and escape.

[0004] However, the brake pads of common escape devices on the market are mostly made of plastic, which not only has limited friction but is also easy to wear, resulting in a small number of effective uses of the escape device and a short lifespan. In addition, the brake pad position lacks isolation. During the process of firefighting, water easily adheres to the wire rope and gradually enters the brake pad along with its transmission, which easily causes the brake pad to slip and greatly reduce friction, and the safety performance will also decrease. Therefore, it is urgent to improve the existing high-rise emergency escape device and provide a high-rise emergency escape device with isolation and waterproof functions. Summary of the invention

[0005] The purpose of the utility model is to provide a high-rise emergency escape device with reasonable design, simple structure, good wear resistance and waterproof isolation function to solve the problems existing in the prior art.

DETAILED DESCRIPTION

[0027] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0028] like Figure 1-7As shown, the utility model high-rise emergency escape device includes a waterproof isolation plate 1, a left box body 2 is provided on the left side of the waterproof isolation plate 1, a right box body 3 is provided on the right side of the waterproof isolation plate 1, a friction wall 6 is fixedly connected to the inner side of the bottom end of the right box body 3, a pulley assembly 7 is installed at the bottom end of the waterproof isolation plate 1, a transmission assembly 8 is provided on the right side of the pulley assembly 7, the transmission assembly 8 is located in the right box body 3, a brake wheel 11 is provided on the outer side of the right end of the transmission assembly 8, a plurality of isolation strips 12 are fixedly connected to the right side wall of the brake wheel 11, a brake block 13 is clamped and installed between two adjacent isolation strips 12, the brake block 13 is located on the inner side of the friction wall 6, and the two are in contact and sliding fit.

[0029] On the basis of the above structure, a connecting plate 4 is fixedly sleeved on the outer sides of the ends of the left box body 2 and the right box body 3 that are close to each other, and the two connecting plates 4 are fixedly connected by a plurality of bolts 5 .

[0030] In this embodiment, the two connecting plates 4 are fixed by bolts 5 to facilitate stable assembly between the waterproof isolation plate 1, the left box body 2 and the right box body 3.

[0031] Based on the above structure, the rope pulley assembly 7 includes a first shaft rod 71, a rope wheel 72 and a gear ring 73. The bearing of the first shaft rod 71 is installed inside the waterproof isolation plate 1. The left end of the first shaft rod 71 is fixedly connected to the rope wheel 72, and the right side of the first shaft rod 71 is fixedly connected to the gear ring 73. The rope wheel 72 and the gear ring 73 are respectively located on the left and right sides of the waterproof isolation plate 1.

[0032] In this embodiment, the rope wheel 72 and the ring gear 73 can rotate synchronously through the first shaft 71, and the transmission assembly 8 can be operated through the ring gear 73.

[0033] On the basis of the above structure, a plurality of threaded columns 9 are distributed in a ring shape around the gear ring 73 . One end of the threaded column 9 is welded and fixed to the waterproof isolation plate 1 , and a nut 10 is threadedly sleeved on the outer side of the other end of the threaded column 9 .

[0034] In this embodiment, the threaded column 9 and the nut 10 are arranged to facilitate the stable installation of the transmission assembly 8 on the right side of the waterproof isolation plate 1 .

[0035] Based on the above structure, the transmission assembly 8 includes a mounting plate 81, a second shaft rod 82, a fixed gear 83 and a reduction gear 84. The mounting plate 81 is located on the right side of the ring gear 73. The second shaft rod 82 is connected to the second shaft rod 82 by a bearing at the center of the mounting plate 81. The left end of the second shaft rod 82 is fixed with a fixed gear 83. Reduction gears 84 are symmetrically arranged on both sides of the fixed gear 83. The two reduction gears 84 are both mounted on the left outer wall of the mounting plate 81 by bearings.

[0036] On the basis of the above structure, the mounting plate 81 is movably sleeved on the outer side of the threaded column 9 , and both the fixed gear 83 and the gear ring 73 are meshed and connected with the reduction gear 84 .

[0037] In this embodiment, when the ring gear 73 rotates, the reduction gear 84 can drive the fixed gear 83, the second shaft 82 and the plurality of brake blocks 13 to rotate rapidly, and the rotation speed can be reduced by friction to achieve the purpose of slow descent.

[0038] On the basis of the above structure, the brake wheel 11 is fixedly sleeved on the outer side of the right end of the second shaft 82, the isolation strip 12 and the brake block 13 are both distributed in a ring shape, and the two are arranged at intervals, the brake block 13 and the friction wall 6 are combined to form a friction pair, and the material of the brake block 13 is powder alloy.

[0039] In this embodiment, the brake block 13 made of powder alloy is not only stronger and more wear-resistant, but also resistant to high temperatures and provides a more stable friction force.

[0040] The working principle of the utility model is as follows:

[0041] When in use, when the wire rope transmission drives the rope wheel 72 to rotate, it can drive the first shaft rod 71 and the ring gear 73 to rotate synchronously, and the ring gear 73 can drive the two reduction gears 84 meshing therewith to rotate, and the reduction gear 84 can only rotate around its own axis, but cannot revolve around the second shaft rod 82, so that the escape device not only runs smoothly but also is not easy to be damaged. At this time, the rotating reduction gear 84 can make the fixed gear 83, the second shaft rod 82, the brake wheel disc 11, the isolation strip 12 and the plurality of brake blocks 13 rotate synchronously, and the brake blocks 13 and the friction wall 6 form a friction pair. When the plurality of brake blocks 13 rotate, the friction between the plurality of brake blocks 13 and the friction wall 6 is used to reduce the rotation speed, so as to achieve the purpose of slow descent escape;

[0042] The existing escape device is composed of two shells directly assembled together, and all components are installed between the two shells. Therefore, fire water is easy to adhere to the transmission wire rope and enter the brake block 13 position, causing the brake block 13 to slip and reduce friction, affecting the safety of the escape device. However, the difference between this solution and the existing escape device is that a waterproof isolation plate 1 is also installed between the left box body 2 and the right box body 3. The waterproof isolation plate 1 forms a separate receiving space between the left box body 2 and the right box body 3, which can isolate the rope wheel 72 from the brake block 13, and can prevent water attached to the surface of the wire rope from entering the brake block 13 position, avoiding the brake block 13 from slipping and reducing friction, thereby ensuring the stable and safe use of the escape device.

[0043] In the present application, a brake block 13 made of powdered alloy is used to replace the brake block 13 made of plastic in the prior art. The brake block 13 made of powdered alloy can provide higher wear resistance and is not afraid of high temperature. It can provide a more stable operating state in a fire accident. In addition, the present application adjusts the number of original brake blocks 13 from four to three, which can increase the contact area between the brake block 13 and the friction wall 6, further increase the friction force, and make the use of the escape device safer.

[0044] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
