Abstract

The invention discloses a safety protection device for tunnel engineering construction. The safety protection device comprises a control unit, a protection shell, a personnel dragging assembly and a safety guarantee assembly. The main body of the protection shell is hemispherical, is hollow and is used for storing living goods and accommodating refugees; a plurality of entrances and exits are formed in the protection shell, channel closing plates are positioned on the entrances and exits, and the normal state is an open state; the personnel dragging assembly comprises a dragging winch, a dragging rope, a dragging rope splicing assembly, a rope head positioning assembly and a trigger switch; the dragging winch is positioned in the protection shell; the dragging winch is used for winding and unwinding the dragging rope, and a rope head positioning assembly is positioned at the end, away from the dragging winch, of the dragging rope; the number of the dragging ropes is multiple, each dragging rope is formed by splicing a plurality of rope bodies through the dragging rope splicing assembly, and the trigger switch is used for controlling operation of the dragging winch; the rope head positioning assembly is used for fixing the splicing rope on a constructor; and the safety guarantee assembly comprises a safety air bag.

Description

technical field [0001] The invention relates to the technical field of refuge rooms, in particular to a safety protection device for tunnel engineering construction. Background technique [0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. [0003] In order to ensure the life safety of construction workers when the tunnel collapses, the existing technology usually adopts the method of building an emergency shelter in the tunnel under construction for the construction workers to avoid when there is a collapse and wait for rescue; the patent number is CN201810083131. The Chinese invention patent of 9 discloses an emergency refuge room for tunnel construction landslides, which overcomes the problem that the outside world cannot understand the situation in the refuge room after the collapse of the existing emergency sh...
