The invention discloses a safety protection device for tunnel engineering construction, and relates to the technical field of construction auxiliary equipment. The device comprises two bases, whereina set of symmetrically arranged compression-resistant tensile parts are hinged to one surface of each of the two bases, the compression-resistant tensile parts comprise sleeves, the inner walls of thesleeves are slidably connected with sliding rods, the circumferential side surfaces of the sliding rods are connected with tensile springs and compression-resistant springs in a sleeve mode, supporting frames are hinged to the surfaces of the two bases, the ends, far away from the bases, of the two sets of compression-resistant tensile parts are hinged to the supporting frames, stretchable mechanisms are mounted between the inner surfaces of the supporting frames, and two symmetrically-arranged buffer pieces are fixedly connected to the surfaces of the supporting frames. According to the device, through design of the stretchable mechanisms and an unwinding roller, a fixed structure of a traditional guardrail is changed into a stretchable structure, and through implementation of a stretchable function, the device can be conveniently transported and rapidly arranged, and the device can adapt to various scene layout requirements through implementation of the stretchable function.
Description
technical field [0001] The invention belongs to the technical field of construction auxiliary equipment, in particular to a safety protection device for tunnel engineering construction. Background technique [0002] Construction guardrails are generally made of iron pipes, which are processed by layers of processes such as seamless iron pipe bending, welding, grinding and polishing, high-pressure baking paint, and filming. They are widely used in the isolation and warning of construction sites. [0003] Ordinary construction guardrails made of iron pipes cannot be changed in structure, occupy a large space, and are not conducive to transportation or carrying, and the existing guardrails do not have anti-collision and energy-absorbing functions, so their practicability is low. Contents of the invention [0004] The purpose of the present invention is to provide a safety protection device for tunnel engineering construction. Through the design of the compression and tensile ...
