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 deceleration type slow down machine has a shell 1 with a pulley deceleration device inside, including an eccentric wheel 2, a pair of auxiliary pulleys 3, a pair of guide pulleys 4 and ropes 5, and an eccentric wheel 2. The fixed shaft on the housing 1 is set in the center, and a pair of auxiliary pulleys 3 and a pair of guide pulleys 4 are symmetrically arranged on both sides of the eccentric wheel 2 through the fixed shaft on the housing 1; one end of the rope 5 is connected from the housing After entering the gap of the body 1, first pass between the eccentric wheel 2 and the guide pulley 4 on one side, and then pass between the auxiliary pulley 3 and the eccentric wheel 2 on the same side, forming an "S" shape. , and 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. ...

Abstract

The pulley deceleration type slow descending machine includes one casing, and one pulley deceleration device including one eccentric wheel, one pair of auxiliary pulleys, one pair of guide pulleys and one rope. The eccentric wheel with a shaft is set in the center inside the casing, the auxiliary pulleys and the guide pulleys are fixed separately on two sides of the eccentric wheel, and the rope penetrates between the pulleys in S form. The pulley deceleration type slow descending machine decelerates by means of the friction force be the pulleys and the friction between the rope and the pulleys.

Description

technical field [0001] The invention relates to the field of slow elevators, in particular to a pulley deceleration type slow elevator. 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 deceleration type desce...
