Portable high-rise descending device

Abstract

The invention provides a portable descending device for tall buildings, which includes a wearing assembly and a screw winding assembly, and the wearing assembly and the screw winding assembly are respectively rigidly connected by a rear shell and a front shell to form a main body of the descending device; In addition, it also includes a wire rope guide buckle fixed on the front of the front shell and a friction grip mechanism. The wire rope guide buckle can quickly ensure that the wire rope enters the spiral groove along a fixed direction, and the friction grip mechanism can ensure the descending speed of the slow descender. ; Finally, it also includes a wedging mechanism placed on the back of the front shell and a crank slider speed manual control mechanism. Control the speed of the descent. Therefore, the present invention not only has a simple structure, but also the modular design of each functional unit effectively guarantees product quality and reduces costs.

Description

technical field [0001] The invention relates to the technical field of high-rise escape applications, in particular to a screw-type speed-adjustable high-rise slow-down device. Background technique [0002] In the era of higher and higher floor buildings, fires in high-rise buildings also occur from time to time. When a fire occurs, people on high floors usually need to descend from balconies or windows to escape. The traditional escape method is to use facilities such as ladders, life-saving bags, and escape wells to escape, but these facilities are expensive, take up a lot of space, and are inconvenient to use. In this case, there have been many different styles of descending devices on the market, such as the Chinese patent with the publication number CN102294084A disclosing a mechanical descending device and the Chinese patent with the publication number CN2566880Y disclosing a reciprocating slow descending device. The lowering devices all use the principle of pulley bl...

The traditional escape method is to use facilities such as ladders, life-saving bags, and escape wells to escape, but these facilities are expensive, occupy a large space, and are inconvenient to use

In this case, there have been many different styles of descending devices on the market, such as the Chinese patent with the publication number CN102294084A disclosing a mechanical descending device and the Chinese patent with the publication number CN2566880Y disclosing a reciprocating slow descending device. The lowering devices all use the principle of pulley blocks. On one side, the user uses gravity to descend to a safe position, and on the other side, the steel wire rope rises to the hanging place to prepare for sending the next person down. In this way, the next person is transported continuously. Because this structure uses the rope It is carried out by means of movement, so once the rope hits an object during movement, the descent will be hindered and the expected effect cannot be achieved

[0003] The location of the fire is random, and it may happen at any location. However, the above-mentioned descending devices need to be installed in advance, and the escape point is fixed, which will be subject to many restrictions in actual use, so there are many available on the market. The hanging slow-down device, such as the Chinese patent with the publication number CN202277620U, discloses a controllable hanging slow-down device. What this patent adopts is that two cone blocks are mutually nested, and the inner cone block is vertically opened. There is a spiral groove, and the steel wire rope is wound in this spiral groove. This solution solves the problem of random escape locations, but each escape device must be equipped with a roll of steel wire rope, that is to say, for a family of three. In addition to the three descending devices, three rolls of steel wire rope must be equipped, and the inner and outer cone blocks are used to compress the steel wire rope for slow descent. The steel wire rope must be relatively thick, otherwise the gap between the two cone blocks is slightly larger, and the steel wire rope may be broken. Detached from the spiral groove, embedded in the two cone blocks, unable to descend
