Embodiment 1

[0082] This embodiment provides a general-purpose speed limiter, which is composed of a turntable or a rotating arm [201], a centrifugal speed-limiting member [202], a speed-limiting shell [203], and a speed-guaranteed spring [204]. It mainly works on the principle of centrifugal force and friction self-locking. Its working principle is as follows: figure 1 shown. Speed-limiting shell [203] is fixed on the object that can provide speed-limiting torque. The rotating shaft [205] of the centrifugal speed-limiting member [202] is fixed on the rotating disk or the rotating arm [201]. The working speed-limiting direction of the centrifugal speed-limiting member [202] is the same as that of its free end, that is, when the rotation of the turntable or the rotating arm [201] is consistent with the direction of the free end of the centrifugal speed-limiting member [202], the centrifugal speed-limiting member [202] Provide working resistance, and the working resistance provided during ...

Embodiment 2

[0089]A rope descending device is composed of a fixed support, a safety rope, a safety belt, a safety belt connecting rope and a descender. It is characterized in that one end of the safety rope is tied to a fixed support, and the other end hangs down to the ground. The safety belt is tied on the person or the article to be lowered. The two ends of the safety belt connecting rope have self-locking hooks, one end is hung on the safety belt, and the other end is hung on the pull ring at the free end of the T-shaped hanging rod of the descender. The safety rope is stuck in the rope groove of the descender. The T-shaped hanging rod of the descender and the entire descending device rotate under the pulling force of the safety belt connecting rope. The T-shaped hanging rod directly presses the safety rope or presses the safety rope through the stopper plate, and the friction force generated when sliding down provides part of the descending resistance. At this moment, the total desc...

Embodiment 3

[0149] The rope descending device of the present embodiment is only made of fixed supports, safety ropes and descenders. The descender is the single-rope or double-rope automatic descender provided in the second embodiment. Both ends of the safety rope have anti-off self-locking hooks and hanging rings embedded in the safety rope. The self-locking hooks can be hung in the hanging rings to form a simple belt-type safety belt; or connect two safety ropes, A large rope loop is formed, and only a simple safety belt is reserved at one end, so that when a person slides down, the speed can be controlled by the safety rope rising on the other side. The safety rope is installed in the rope groove of the descender. The size of the self-locking hook is greater than the inner diameter of the rope groove of the descender, so that the safety rope cannot be pulled out from the rope groove of the descender. The pull ring of the T-shaped hanging rod of the descender is hung on the fixed supp...

Abstract

The invention discloses a rope descending device, which consists of a fixed supporting object, a safety rope, a safety belt, a safety belt connecting rope and a descending device. The invention mainly relates to the fields of rope descending, speed limiters and speed limiting pulleys. The fixed supporting object provides a supporting point for the safety rope; and the safety belt and the safety belt connecting rope are connected with the descending device and a person. The descending device has a rope groove for clamping the safety rope and can slide down along the safety rope. Or the descending device is used in a fixed pulley mode. The descending device consists of a base, a T-shaped suspending rod base, a T-shaped suspending rod, a selectable limiting plate, a speed limiter or a manual control handle, and a symmetric design can prevent a reverse installation problem. Descending devices fall into a single rope type and a double rope type according to the number of rope grooves; and according to speed control mode, descending devices fall into a manual type, an automatic type and a manual-autonomic type. The automatic descending device is provided with a speed limiter for controlling the descending speed automatically and is used as a speed limiting dynamic / fixed pulley. The invention also provides a common speed limiter based on a centrifugal force and friction self-locking principle. The rope descending device is simple, safe and reliable in structure and operation and suitable to be used for emergence escape from high-rise buildings.

Description

technical field [0001] The technical field of the invention is the field of rope descent, especially the field of rope descent for escape from heights, and the field of speed governors and speed limiting pulleys. Background technique [0002] In recent years, there are more and more high-rise buildings, and they are getting higher and higher. After a safety accident such as a fire occurs, traditional escape routes such as stairs are easily destroyed. Moreover, fire-fighting equipment in many places, such as ladders and water guns, cannot reach the rescue height. The existing descenders used for outdoor sports need to manually control the descending speed, and generally do not have a good error-proof design, and once installed in reverse, it may cause serious consequences. It is not suitable as escape equipment for ordinary people without special training in emergency situations, especially not suitable for the elderly, weak, sick, disabled and children. [0003] In additi...
