Abstract

The invention discloses a convenient-using type blasting insulating protecting device. The device comprises a protecting device body, a fixing plate, a boss, a first supporting rod and a protecting net, wherein the protecting plate which is connected to a bottom plate though an elastic layer is arranged at the left side of the protecting device body; the fixing plate is arranged at the right side of the bottom plate through a buffering spring, and the upper end and the lower end of the fixing plate are connected to a baffle plate; the boss is arranged at the right side of the baffle plate; the first supporting rod is connected with the upper end of the fixing plate through a rotating hinge, and the lower end of the first supporting rod is connected with a second supporting rod through a rotating hinge; the left end of the second supporting rod is inserted into a fixing sleeve which is positioned below the right side of the fixing plate; the protecting net is arranged at the inner side of the first supporting rod, and the lower part of the protecting net is connected to the connecting rod. The convenient-using type blasting insulating protecting device is capable of protecting a blasting person, is convenient to mount and can be repeatedly used for a plurality of times.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a convenient blasting isolation protection device. Background technique [0002] At present, the excavation construction of hard rock and some soft rock in domestic tunnels is mainly based on blasting excavation. For blasting construction in densely built areas or with strict safety distance requirements, good safety protection measures must be required. According to the survey, the tunnel In blasting construction, because the flying rocks are limited by the initial support around the tunnel, the flying rocks will fly in one direction, so as long as the safety protection of the flying rocks running direction is done well, the purpose of safety protection can be achieved. At this stage, blasting construction There are mainly two methods in the process: (1) For those sites that meet the safety distance requirements, the security warning is mainly adopted outside the blasting safet...
