Problems solved by technology

But there are two problems worthy of attention. One is that friction will generate heat, especially when the distance is long and continuous use. There is a big change due to the difference in weight, and even the difference can be more than five times

Embodiment 1

[0027] Such as Figure 1 to Figure 7 As shown, a high-altitude descending device includes a housing 1, a sheave 3, a shaft 2 and a rope 10 installed in the groove of the sheave 3; 5 and a slow-down mechanism composed of four pendulum needle frames 6 meshed with spike gears.

[0028] The shaft 2 passes through the center of the sheave 3, and is installed vertically and rotatably with the two side plates of the housing 1, and the spike gear 5 is arranged coaxially with the sheave 3 , the spike gear 5 and the sheave 3 are provided with a key 4 and fixedly connected with the shaft 2 .

[0029] The four pendulum needle racks 6 of the slow-down mechanism are arranged on the periphery of the pointed gear 5, installed between the side wall of the housing 1 and the middle partition 111 of the housing, and can swing freely, each A swing frame 6 includes a swing frame 61 with journals on both sides, and two pairs of swing needles 62 fixed in the swing frame 61. The teeth of the pointed...

Embodiment 2

[0036] The situation of embodiment 2 is basically the same as that of embodiment 1, the difference is that embodiment 2 has two sets of slow-down mechanisms, which are respectively arranged on the left and right sides of the sheave ( Figure 8 ). At this time, because the damping resultant force of the two sets of slow-down mechanisms is relatively large. It is especially suitable for the slow descent of more than two people or heavy objects. Certainly also can be made into the slow descending device of more than three sets of slow descending mechanisms. It can also be made into one, two, three, or more than four swing needle racks in the slow-down mechanism (four in embodiment 1); it can also be made into more than three pairs of swing needles in each swing rack (Embodiment 1 is two pairs), which will not be repeated one by one here.

Abstract

The invention relates to a rescue and escape device, and in particular relates to a high-altitude descent control device, which is mainly used when a person is required to urgently descend in a high-rise or other high-altitude situations, and required to fall safely at a certain speed. The high-altitude descent control device comprises a shell, a grooved pulley in the shell, a shaft, a rope arranged in a grooved wheel groove, and is characterized in that more than one set of descending mechanism is arranged in the shell; and each set of descending mechanism mainly comprises a pointed gear and more than one balancing point rack which is engaged with the pointed gear. The high-altitude descent control device is simple in structure, safe and reliable, enables the descending speed to be stabilized in a safety value, and is a high-altitude descent control device with a novel structure.

Description

technical field [0001] The present invention relates to a rescue and escape equipment, specifically a high-altitude slow descent device, which is mainly used for emergency descent in high-rise buildings or other high-altitude places, but requires a safe landing at a certain speed. Background technique [0002] With the development of the economy, high-rise buildings have sprung up everywhere. When dangerous situations occur in high buildings or high altitudes, such as fires, earthquakes, etc., personnel need to escape or evacuate by themselves. Therefore, various high-altitude descending devices have attracted the attention of people from all walks of life. [0003] The key to the high-altitude descending device technology is slowing down. To achieve slowing down, it is necessary to have a slowing down device that can effectively produce damping effect. At present, there are many types of such devices at home and abroad, but in fact there are not many that are put on the m...
