Abstract

The invention relates to the field of construction safety, in particular to an anti-collapse safety helmet for shaft sinking operation. The invention aims to provide the anti-collapse safety helmet for shaft sinking operation, so as to solve the problems of protecting the mouth and nose of a victim to breathe smoothly and preventing the victim from being hit by falling soil when a collapse phenomenon occurs during shaft sinking. The anti-collapse safety helmet comprises a helmet shell, a wearing cavity with a downward opening is formed in the helmet shell, a safety mechanism is arranged on the upper side of the wearing cavity, and the safety mechanism comprises a reaction cavity which is formed in the helmet shell and located on the upper side of the wearing cavity; and a rotary protection disc rotationally connected to the inner wall of the helmet shell is arranged in the reaction cavity.

Description

technical field [0001] The invention relates to the field of construction safety, in particular to an anti-collapse safety helmet used for drilling wells. Background technique [0002] Sinking refers to the work of digging a shaft in rock and soil. During the drilling operation, due to various reasons, landslides often occur. This phenomenon is unpredictable and often causes great harm. The landslides during drilling often carry a lot of sand. When digging a well, if you encounter landslides, even if you can get out in time with the help of your teammates, you will be buried by the sudden collapse of the soil, or even hit your head by the falling sand, covering your mouth and nose, so that the victims cannot Breathe smoothly, cause life and health threat to builder, so it is necessary to provide a kind of device that can solve the above problems. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to prov...
