Description
Technical Field
The utility model relates to a drilling device, in particular to a drilling device for drilling holes in a concrete structural slab.
Background
In secondary structure construction or house decoration, it is often necessary to perform a drilling operation on a concrete structure wall or a floor top plate of a concrete structure; the hand-held electric drill is usually used for drilling, a drill bit of the electric drill rotates to enter a concrete structure wall, concrete dust generated by drilling is blown out from the drilling hole, serious pollution is caused to the construction environment, particularly, the body health of construction personnel can be damaged, the dust blown out is effectively collected, the construction environment is protected to the maximum extent, and the problem which needs to be solved urgently in a construction site is solved.
Disclosure of Invention
The utility model provides a drilling device for drilling holes in a concrete structural slab, which solves the technical problem of effectively collecting dust which is generated by drilling and is raised outwards.
The utility model solves the technical problems by the following technical scheme:
a drilling device for drilling holes on a concrete structural slab comprises a concrete wall body, a handheld electric drill and a hemispherical transparent plastic protective cover, a drill bit clamping seat is arranged on the hand-held electric drill, a drill bit is arranged on the drill bit clamping seat, a central bayonet is arranged at the center of a hemisphere of the hemispherical transparent plastic protective cover, a folding rubber telescopic cylinder is connected on the round cover opening of the hemispherical transparent plastic protective cover, a dust collecting nozzle is arranged at the position, close to the circular cover opening, of the hemispherical transparent plastic protective cover, a dust collecting bottle is connected onto the dust collecting nozzle, a drill bit clamping seat of the hand-held electric drill is sleeved in the central clamping opening, the outer side port of the folding rubber telescopic cylinder is connected to the wall surface of the concrete wall body in an abutting mode, and the drill bit is sealed in a closed space formed by the hemispherical transparent plastic protective cover, the folding rubber telescopic cylinder and the wall surface of the concrete wall body.
The dust collecting bottle is in threaded connection with the dust collecting nozzle, and dust falling water is arranged in the dust collecting bottle.
The utility model realizes the closed operation of wall drilling, controls the dust generated by drilling in the hemispherical transparent plastic protective cover, and effectively absorbs the dust by the dust fall water in the dust collecting bottle, thereby preventing the flying dust from causing the harm to the lung of constructors and the pollution to the environment.

fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is described in detail below with reference to the accompanying drawings:
a drilling device for drilling holes on a concrete structural slab comprises a concrete wall body 4, a handheld electric drill 1 and a hemispherical transparent plastic protective cover 2, wherein a drill bit clamping seat 9 is arranged on the handheld electric drill 1, a drill bit 5 is arranged on the drill bit clamping seat 9, a central bayonet 10 is arranged at the center of a hemisphere of the hemispherical transparent plastic protective cover 2, a foldable rubber telescopic cylinder 3 is connected to a circular cover opening 12 of the hemispherical transparent plastic protective cover 2, a dust collecting nozzle 11 is arranged at a position, close to the circular cover opening 12, of the hemispherical transparent plastic protective cover 2, a dust collecting bottle 7 is connected to the dust collecting nozzle 11, the drill bit clamping seat 9 of the handheld electric drill 1 is sleeved in the central bayonet 10, an outer side end opening of the foldable rubber telescopic cylinder 3 is abutted to the wall surface of the concrete wall body 4, and the drill bit 5 is sealed on the wall surface of the hemispherical transparent plastic protective cover 2, The folding rubber telescopic cylinder 3 and the wall surface of the concrete wall 4 form a closed space.
An external thread 6 is arranged on the dust collecting nozzle 11, a dust collecting bottle 7 is screwed on the dust collecting nozzle 11, and dust falling water 8 is arranged in the dust collecting bottle 7.
The length of the folding rubber telescopic cylinder 3 is larger than the depth of a drilled hole, when an operator holds the electric drill to drill the hole, the hand-held electric drill 1 is pushed to the wall surface by the contraction of the folding rubber telescopic cylinder 3 along with the penetration of a drill bit, and in the whole process of drilling, the drilled hole is sealed in a closed space formed by the hemispherical transparent plastic protective cover 2, the folding rubber telescopic cylinder 3 and the wall surface of a concrete wall body 4, so that the raised dust can only enter the dust collecting bottle 7, and the pollution to the environment outside the hemispherical transparent plastic protective cover 2 is protected.
