Problems solved by technology

However, in the two major categories of products, the fire escape cabin and the elevator anti-fall protection in the building, there is currently no dedicated speed control and anti-fall mechanism, so that the high-rise fire rescue cabin without electric drive still uses electromagnetic damping or hydraulic damping. After completing the slow descent, these two types of machinery have always had potential safety hazards and are unreliable. The out-of-control protection of the elevator in the building has been using the safety system 150 years ago to prevent falling. After the box, it suddenly lost control and the box fell, resulting in 2 accidents, or it could not get stuck at all, and there was no anti-fall effect

Embodiment Construction

[0009] figure 1 A speed control fall arrester shown is composed of a rope winding wheel assembly, a ratchet (8), a speed-increasing gear set, and the speed control mechanism is fixed on three blocks through the main shaft (7) and its bushing (6) (25) (22). Between the fixed plates, between the upper fixed plate (12) and the middle partition (31), a rope winding wheel assembly and a ratchet (8) are fixed, which are set on the upper end of the main shaft (7). The ratchet is connected with the main shaft by a square key, and the two parts Can only rotate together, have the chute for steel rope to embed on the axial surface of rope winding wheel (34), be fixed with a plurality of ratchet shafts (10) above the wheel end face, be equipped with ratchets (9) on the shaft, shaft The upper end is equipped with a washer circlip (11) to prevent the pawl from moving axially. The pawl can rotate under the action of the tension spring (3) to ensure that the pawl is engaged with the ratchet (...

Abstract

The invention discloses a speed control fall arrester, which is characterized in that: a rope winding wheel assembly, a ratchet wheel, a speed-increasing gear set, and a speed control mechanism driven by a steel wire rope are fixed between three fixing plates through a main shaft, and the upper fixing plate A rope winding wheel assembly and a ratchet are fixed between the middle partition and are set on the main shaft. Multiple ratchets are fixed on the rope winding wheel and a centrifugal block for releasing the ratchets is composed of an assembly. Between the middle partition and the lower bottom plate A speed-increasing gear set and a speed-control mechanism are fixed between them, which are used to control the deceleration of the high-rise fire rescue cabin, and can also be used as a new type of machinery for the fall protection of high-rise elevators.

Description

(1) Technical field [0001] The invention is a new type of machine (2) Background technology [0002] In the prior art, the speed control of a falling object is controlled by an electric-driven hoist, such as elevators, mine cars, lifting materials at ports and wharves, and rail cable cars for transporting people in tourist attractions, all using the above-mentioned machines. However, in the two major categories of products, the fire escape cabin and the elevator anti-fall protection in the building, there is currently no dedicated speed control and anti-fall mechanism, so that the high-rise fire rescue cabin without electric drive still uses electromagnetic damping or hydraulic damping. After completing the slow descent, these two types of machinery have always had potential safety hazards and are unreliable. The out-of-control protection of the elevator in the building has been using the safety system 150 years ago to prevent falling. After the box, it suddenly lost contro...
