Abstract

The invention discloses a hydraulic descent control device which mainly comprises a one-way throttle valve bank, a hydraulic pump (or a hydraulic motor) and a reel component. The one-way throttle valve bank is fixedly mounted on the hydraulic pump, an upper oil port of the one-way throttle valve bank is communicated with an upper oil port of the hydraulic pump, and a lower oil port of the one-way throttle valve bank is communicated with a lower oil port of the hydraulic pump. A mounting flange of the hydraulic pump is connected with a reel frame of the reel component through a screw, an 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 frame can be connected with a fixing body through an upper fixing rope and a lug on the upper portion of the reel frame, and a rope on the reel is connected with a human body through a human body connecting rope at the lower end of the reel. The hydraulic descent control device can be used for realizing high-altitude stability and safe descent of a human body, particularly can play a great role in personnel rescue of high-rise buildings, and has a wide application prospect if serving as a fire fighting instrument.

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 group and a winch 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...
