Abstract

The invention discloses a hydraulic descent control device which mainly comprises a one-way throttle valve group, a hydraulic pump and a reel component, wherein the one-way throttle valve group is fixedly installed on the hydraulic pump, and the upper oil port of the one-way throttle valve group is communicated with the upper oil port of the hydraulic pump; the lower oil port of the one-way throttle valve group is communicated with the lower oil port of the hydraulic pump; the mounting flange of the hydraulic pump is connected with a reel frame through screws and the reel component; the output shaft of the hydraulic is connected with one end of a reel through keys; the other end of the reel is connected with a support shaft through the keys; the reel frame can be connected with a fixing body through a lug seat and an upper fixing rope which are above the reel frame; and the rope on the reel is connected with a human body through a body connection rope at the lower end of the rope. When the hydraulic descent control device disclosed by the invention is used, the human body can be stably and safely descended slowly from high positions, and particularly, the hydraulic descent control device can play an important role in rescuing the staff of high-rise buildings, and has a wide application prospect when being used as a fire-fighting appliance.

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, use the descender to escape from the window. The use of the existing descending device re...
