Abstract

The invention discloses a hydraulic descent control device, which mainly consists of a one-way throttle valve bank, a hydraulic pump and a reel assembly, wherein the one-way throttle valve bank is fixedly arranged on the hydraulic pump; the upper port of the one-way throttle valve bank is communicated with the upper port of the hydraulic pump; and the lower port of the one-way throttle valve bank is communicated with the lower port of the hydraulic pump. A mounting flange of the hydraulic pump is mutually connected with a reel rack of the reel assembly through bolts; the output shaft of the hydraulic pump is connected with one end of a reel through a key; and the other end of the reel is connected with a support shaft through a key. The reel rack can be connected with a fixed body through a lug and an upper fixed rope above the reel rack. A rope on the reel is mutually connected with a human body through a human body connecting rope at the lower end of the reel. By utilizing the hydraulic descent control device disclosed by the invention, a human body can stably and safely descend slowly. The hydraulic descent control device can perform an important action especially personnel rescue of high-rise buildings. If used as a fire-fighting apparatus, the hydraulic descent control device is wide in application prospect.

Description

technical field [0001] The invention relates to a hydraulic descending device, in particular to a hydraulic descending device composed of a hydraulic pump, a one-way throttle valve and a winch wheel assembly. Background technique [0002] At present, high-rise buildings such as high-rise office buildings and residential buildings have been widely used. In the event of emergency events such as fires and earthquakes, it is necessary to adopt reasonable self-rescue and rescue methods. The common rescue method is to evacuate through rescue channels, or use Even so, casualties often occur in the above emergencies. Strengthening emergency handling and self-rescue can greatly reduce or even avoid major casualties. If high-rise buildings can be equipped with certain personnel self-rescue equipment, in the event of an emergency, more escape methods can be selected for self-rescue. For example, using a descending device to escape from a window, etc. The use of the existing descendin...
