Abstract
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...
