Problems solved by technology

[0002] When an accident occurs in high-altitude operations, or a fire occurs in a high-rise, the traditional way of rapid escape is to escape through facilities such as soft ladders, life-saving bags, and escape wells. However, these facilities are expensive, occupy a large space, and are inconvenient to use, especially for the elderly. Not suitable for the weak, sick and young
In this case, the slow down machine is applied, but most of the current slow down machines have the disadvantages of bulky, complex structure, high production cost, easy to break or poor slow down effect, etc.

Embodiment Construction

[0010] As shown in Figure 1, a pulley-type descending device has a housing 1 with a pulley reduction device inside, including an eccentric wheel 2, a pair of auxiliary pulleys 3, a pair of guide pulleys 4 and a rope 5, and an eccentric wheel 2 The fixed shaft on the housing 1 is arranged in the center, and a pair of auxiliary pulleys 3 and a pair of guide pulleys 4 are respectively symmetrically arranged on both sides of the eccentric wheel 2 through the fixed shaft on the housing 1; After entering the gap of 1, first pass between the eccentric pulley 2 and the guide pulley 4 on one side, and then pass between the auxiliary pulley 3 and the eccentric pulley 2 on the same side, forming an "S" shape. Then pass between the auxiliary pulley 3 and the eccentric wheel 2 on the other side, and pass through between the guide pulley 4 and the eccentric wheel 2 on this side, and finally lead out from the gap of the housing 1 .

[0011] The eccentric wheel 2 is composed of an inner wheel...

Abstract

The present invention discloses a pulley descent control device, providing with a casing in which a pulley decelerating device is arranged. The present invention comprises an eccentric wheel, a pair of assistant pulleys, a pair of end pulleys and a rope. The eccentric wheel is arranged at the center through the dead axle on the casing. The pair of assistant pulleys and the pair of end pulleys are respectively arranged at the two sides of the eccentric wheel symmetrically through the dead axle on the casing. The rope passes round the pulleys in S-shape. The operational principle of the pulley descent control device is that the friction between the pulleys and the friction between the pulleys and the rope together play the role of deceleration and descent control.

Description

technical field [0001] The invention relates to the field of descending devices, in particular to a pulley type descending device. Background technique [0002] When an accident occurs in high-altitude operations, or a fire occurs in a high-rise, the traditional way of rapid escape is to escape through facilities such as soft ladders, life-saving bags, and escape wells. However, these facilities are expensive, occupy a large space, and are inconvenient to use, especially for the elderly. It is not applicable to the weak, sick and young. In this case, the slow descending machine has been applied, but most of the present slow descending machines have the disadvantages of bulky, complex structure, high production cost, fragile or poor slowing down effect. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the prior art, the present invention provides a pulley type descending device with ...
