Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Reference is made to the accompanying drawings. The furred ceiling drilling auxiliary device of this embodiment is including removing slide, fixed support rod 3, lifting support pole 4, electric drill and drive assembly. Wherein, the movable sliding plate comprises a horizontal supporting plate 1 and a rolling pulley 2 fixed at the bottom of the supporting plate 1. The fixed support bar 3 is vertically arranged on the support plate 1 and has a cavity 30 inside, and the opposite walls of the two cavities 30 are provided with convex strips 31 extending along the vertical direction. The lifting support rod 4 is arranged in the fixed support rod 3 through the cavity 30. Specifically, the whole lifting support rod 4 is a square column, and at least two opposite side wall surfaces are provided with sliding grooves 41 corresponding to the shape and size of the convex strips 31, and the sliding grooves 41 also extend in the vertical direction. In this embodiment, the four side walls of the lifting support rod 4 are provided with sliding grooves 41, and the cross section of each sliding groove is substantially square. The convex strip 31 is correspondingly positioned in the sliding groove 41, so that vertical guiding is provided for the ascending and descending of the lifting support rod 4 on one hand, and the stability of the whole device is improved during high-speed operation of the electric drill on the other hand. The top opening of the cavity 30 of the fixed support rod 3 is further provided with a dustproof cover plate 10, and the dustproof cover plate 10 is provided with a hole for the lifting support rod 4 to pass through.

The transmission assembly is arranged on one side of the lifting support rod 4 and comprises an upper toothed fixed pulley 5 provided with a hand crank 8, a chain 6 and a lower toothed fixed pulley 7 positioned below the upper toothed fixed pulley 5. The chain 6 is connected with the upper tooth-shaped fixed pulley 5 and the lower tooth-shaped fixed pulley 7 and is fixedly connected with the bottom of the lifting support rod 4, so that the lifting support rod 4 can be driven to ascend or descend by rotating the hand crank 8. In this embodiment, the lifting support rod 4 can be retracted into the cavity 30 of the fixed support rod 3 substantially after being lowered, thereby facilitating the portability and transportation of the whole device. In particular, the upper tooth-shaped fixed pulley 5 is also provided with a limiting rod 9. When continuous drilling is needed, after the drilling of the previous hole is finished, the limiting rod 9 can be leveled to limit the rotation of the gear type fixed pulley with the handle, and after the next hole is positioned, the limiting rod 9 is pulled up to continue operation. In order to prolong the service life of the transmission assembly, the lower tooth-shaped fixed pulley 7 is fixed in the lower protective cover 12 through a fixed shaft 15, and the upper tooth-shaped fixed pulley 5 is fixed in the upper protective cover 11 through a hand crank 8.

An electric drill fixing splint 13 is arranged at the upper end of the lifting support rod 4, and the electric drill fixing splint 13 is provided with a bolt and a sliding groove for fixing an electric drill 14. Consequently, can easily reach the floor below of wanting the drilling through the removal of backup pad 1, then can break away from complicated scaffold or the not high double ladder of security through drive assembly, the operation personnel stand on the floor and can carry out the furred ceiling drilling operation of floor, have not only improved the efficiency of construction, have reduced the construction risk moreover.

During the use, when constructor need carry out the furred ceiling drilling operation, install electric drill 14 on electric drill fixed splint 13 earlier, after fixing through backup pad 1 location, rotate upper tooth form fixed pulley 5 and make lift support rod 4 rise, start the electric drill and begin to drill after touching the floor. After the drilling is finished, the upper toothed fixed pulley 5 is reversely rotated by the hand crank 8, and the lifting support rod 4 can be lowered, so that one-time drilling work is finished. If a plurality of holes need to be drilled continuously, the limiting rod 9 is leveled after the previous hole is drilled, so that the upper toothed fixed pulley 5 rotates by 180 degrees at most, the descending value of the lifting support rod 4 is smaller, and the workload of ascending the lifting support rod 4 in the next operation can be reduced.

It should be noted that the above describes exemplifying embodiments of the invention. However, it should be understood by those skilled in the art that the present invention is not limited to the above embodiments, which are only used for illustrating the principle of the present invention, and that various changes and modifications may be made without departing from the scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
