Abstract

The invention relates to a deep well mechanical rescue device, which comprises a control device and an enclasping device and is characterized in that a connection rod is arranged between the control device and the enclasping device, an executing part of the control device and an executing part of the enclasping device are transferred through steel wire ropes, the control device is arranged at the top, and the enclasping device is arranged at the bottom end of the deep well mechanical rescue device for implementing rescue. When in use, the rescue device with the structure is placed into the well, and a supporting plate supports trapped persons by adjusting the control device. Simultaneously, protection plates on two sides fold to surround the trapped persons from around in an annular mode to ensure the safety of the trapped persons. After the trapped persons are ensured to be safely firmed, the trapper persons and the rescue device are pulled out of the well bottom by means of labor power, thereby avoiding danger caused by the fact that rescuers go into the well to rescue the trapped persons. Therefore, the rescue method of the deep well mechanical rescue device is simple, easy to implement and strong in operability, the rescue cost is low, the trapper persons can be rescued out of the well bottom successfully, firefighters have no need to go into the well to rescue the trapped persons, and life safety of the trapper persons and the firefighter are ensured.

Description

A kind of deep well mechanical rescue device

Technical field

The invention belongs to deep well mechanical rescue technical field, particularly relate to a kind of deep well mechanical rescue device.

Background technology

In recent years, the number of times that fire brigade's participation disposes well rescue increases gradually, but deep well rescue device category is little on the market at present, mode that traditional rescue mode digs a well, little chap fireman goes into the well.Due to deep-well situation complexity, neural mouthful too little domestic shortage oxygen, rescue difficulty greatly to suing and labouring, rescued personnel's life security and had very large threat, rescue Philadelphia airplane crash, the a large amount of human and material resources of rescue process consumption, sometimes also can delay the valuable rescue time, people can not be freed from rescue process, can not guarantee rescuer's safety.It is reported: fire fighter goes into the well while suing and labouring, must be upside down.Head is will be in a large number congested like this, and overlong time just has life security, after each rescue fire fighter's health all can collapse in the several years, pale, even can be in peril of one's life.
