Speed slowing and reducing mechanism

Abstract

The invention discloses a speed slowing and reducing mechanism used for abseiling-style escape and outdoor movement. The speed slowing and reducing mechanism comprises a shell body, a driving piece and a driven piece, wherein hydraulic oil is filled in the shell body; the driving piece and the driven piece are respectively arranged in the shell body; the contact end surfaces of the driving piece and the driven piece are engaged with each other in shape; the driving piece is rotated around a central axis to drive the driving piece to move along the central axis under the effect of external force, so that the hydraulic oil flows in and out between the driving piece and the driven piece periodically; therefore, the damping energy consumption is generated. According to the speed slowing and reducing mechanism, the circulating movement of the driving piece is converted into reciprocating movement of the driven piece; the damping is generated through oil holes in the driving piece, so that additional transmission mechanisms, such as gears, are almost not required to be added in addition to a fixing mechanism when the speed slowing and reducing mechanism is used; the overall structure is sealed and is compact; external energy or other artificial control and interference are not required; main movement parts work in the hydraulic oil, so that the main movement parts are almost not required to be maintained and cared, and the reliability is extremely high.

Description

technical field [0001] The present invention relates to a high-rise building escape or outdoor sports device, in particular to a slow speed control device that can be used for rope descent escape or outdoor sports, or applied to other conditions that require automatic speed control and constant speed without external energy or human control. mechanism. Background technique [0002] With the development of the urbanization process, there are more and more high-rise buildings. The use of high-rise buildings not only improves the utilization rate of urban land and shows the style of the city, but also brings some safety hazards. For example, when disasters such as fires and earthquakes break out, people who are in high-rise buildings are generally difficult to escape. [0003] At present, high-rise buildings are rarely equipped with escape tools. When a disaster occurs, people on the upper floors of the building can only escape through safe passages or waiting for rescue. Un...

Problems solved by technology

[0003] At present, high-rise buildings are rarely equipped with escape tools. When a disaster occurs, people on the upper floors of the building can only escape through safe passages or waiting for rescue. Under such circumstances, the life safety of the trapped people will be greatly threatened; at the same time, with the rise of outdoor sports, the needs and requirements of outdoor sports for slow descent equipment are also getting higher and higher. To solve the above problems, people have developed Descending devices and other escape tools, but the existing Descending Devices have the following disadvantages: ① The damping in the initial state is the smallest, and it slides at the maximum speed, so that the escape personnel can only slow down the descending speed by increasing the damping, such as improper operation or The failure of the descending device may easily cause safety hazards such as excessively fast descent speed; ②Most descending devices need to be manually controlled to descend, and the escape personnel generally operate for the first time when escaping. ③The structure is complicated, the manufacturing cost is high, it is difficult to be popularized and applied, and it is not generally accepted by the public
