Description

Blasthole safety device

Technical Field

The utility model relates to the technical field of blasting protection equipment, in particular to a blast hole safety protection device.

Background

In the construction of foundation engineering, the problem that stubborn stones or rocks and the like are needed to be solved by blasting operation is usually solved, wherein the blasting operation comprises the steps of drilling blast holes into a medium to be blasted, excavating a powder chamber or laying explosive on the surface of the medium to be blasted, putting an initiating detonator into the medium to be blasted, and then detonating. According to different charge shapes and charge modes, the blasting method is mainly divided into a blast hole method, a charge room method and a bare charge method, and the blast hole method is widely applied and is a basic form of a rock and soil blasting technology due to the advantages that the blast hole method does not need complex drilling equipment and can be constructed under various complex conditions.

Blasting by using a blasthole method requires that blastholes with various apertures are drilled in a medium, and the blastholes are detonated through procedures of charging, putting into detonating, blocking the apertures, connecting wires and the like. In blasting operation, because of poor quality of blocking up the charging orifice, excessive charging, uneven rock mass and other factors, blasting flying stones can be generated, and the personal safety of surrounding personnel can be directly influenced by the flying stones generated by blasting.

At present, in order to prevent the flying stones generated by blasting from splashing to cause casualties, before blasting operation, a gun is protected by the blasting protection article, and the gun is woven by waste tires, so that the gun has high strength, elasticity and toughness, is not easy to break and has a certain weight.

In order to apply the cannon to different scenes, numerous products are derived from the cannon, for example, an orifice anti-flying stone device for pile foundation blasting construction is disclosed in a patent with publication number of CN214657099U, an upper frame structure and a lower frame structure are made of 8I-steel beams with length of 3.5m, the end parts of the I-steel beams are welded, a buffer device is arranged between the upper frame structure and the lower frame structure, and the buffer device is a single-layer rubber cannon cover.

Meanwhile, in the 20 th section of the patent, an upper frame structure and a lower frame structure are fixedly connected through 36M 30 bolts, and the upper frame structure and the lower frame structure clamp a single-layer rubber gun through bolts. However, in this patent, once the part of the gun quilt is damaged, the whole gun quilt can only be replaced, and as the gun quilt is sewn by rubber, once the part is damaged, the whole gun quilt needs to be scattered and detached completely, the whole gun quilt is generally replaced directly, but all bolts need to be removed in sequence to replace the gun quilt, so that the time is wasted.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a blast hole safety protection device, which solves the problems that after the local damage of a gun quilt, the whole gun quilt needs to be replaced, and more bolts need to be detached in sequence, so that a great amount of time is wasted in replacing the gun quilt.
