Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a stable hole drilling device for building walls. Background Art

[0002] Drilling holes in building walls through a hole drilling device facilitates subsequent equipment installation, structural reinforcement, decoration, inspection and maintenance, as well as renovation and expansion.

[0003] A wall hole drilling device for decoration with the patent application number CN202110758309.7 has an overall structure that is not convenient for storage and folding, occupies a large space, and uses a sheath for dust prevention. It cannot be closely attached to an uneven wall surface, and the vibration generated during hole drilling is also likely to cause internal dust to overflow. At the same time, the waste chips generated during hole drilling cannot be automatically collected and processed. When the sheath is separated from the wall, the waste chips located at the outer end inside the sheath are likely to spill out. Summary of the Invention

[0004] The problem solved by the present invention is to provide a stable hole drilling device for building walls, which solves the above technical problems.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A stable hole drilling device for building walls includes a mobile trolley, on which a lifting platform is installed in a lifting manner. A clamping block is installed on the lifting platform, and a U-shaped seat is clamped on the lifting platform. A plurality of guide columns are installed on the bottom side of the U-shaped seat. The guide columns penetrate through the lifting platform and the mobile trolley and are installed with a bottom plate. Side seats are symmetrically installed on the U-shaped seat. A vertical seat is arranged inside the two side seats, and a rotating seat is installed between the two side seats. A lifting seat is slidably installed on the vertical seat and the rotating seat. A support plate is installed on the lifting seat. A sliding frame is slidably installed on the support plate. A third motor is installed on the sliding frame. The output end of the third motor is installed with a drill bit, and a slag collection and dust prevention mechanism is installed outside the drill bit.

[0007] Preferably, first air cylinders are installed around the top of the lifting platform, and the telescopic ends of the first air cylinders are connected to the mobile trolley.

[0008] Preferably, a first motor is installed outside one of the side seats, and the output end of the first motor is fixedly connected to the rotating seat.

[0009] Preferably, a first guide rail is provided on the vertical seat and the rotating seat, and the lifting seat moves along the first guide rail. Second air cylinders are installed at both ends of the lifting seat. An installation groove is opened on the top side of the rotating seat, and a second motor is installed in the installation groove. The output end of the second motor is installed with a winding wheel, and a connecting rope is connected to the winding wheel and is connected to the lifting seat.

[0010] Preferably, a plate seat is provided at the top of the outer side of the vertical seat, and a limiting plate is installed in the plate seat. A clamping groove is formed at the bottom of the outer side of the rotating seat.

[0011] Preferably, second guide rails are symmetrically installed on the top side of the support plate, and the second guide rails are slidably installed with the sliding frame. A sliding groove is formed on the support plate. A third air cylinder is installed at the bottom side of the support plate. A sliding plate is installed at the bottom side of the sliding frame, and the sliding plate penetrates through the sliding groove and is connected to the telescopic end of the third air cylinder.

[0012] Preferably, the slag collecting and dust-proof mechanism includes an annular cover. Rotating arms are symmetrically installed on the annular cover. Rotating shafts are symmetrically installed on the outer side of the sliding frame, and the rotating shafts are connected to the rotating arms through bearings. A fourth motor is installed on one of the rotating arms, and the output end of the fourth motor is connected to the rotating shaft.

[0013] Preferably, a connecting annular cloth is installed between the annular cover and the third motor. An inner cavity is formed on the annular cover. A plurality of springs are installed in the inner cavity, and the springs are connected to the annular seat. An airbag is installed on the annular seat. A retaining ring is installed on the inner side of the outer end of the annular cover.

[0014] Preferably, a material pipe is connected to the bottom side of the annular seat, and the material pipe is connected to the collecting cylinder.

[0015] Preferably, the specific operation steps of the device are as follows:

[0016] Step 1: Drive the lifting table to lift and lower through the operation of the first air cylinder. When the lifting table rises, the clamping block is clamped into the mouth-shaped seat, driving the mouth-shaped seat, the guide post and the bottom plate to move upward. Move through the rollers at the bottom of the moving trolley. When the lifting table descends, the mouth-shaped seat, the guide post and the bottom plate descend synchronously until the bottom plate contacts the ground, realizing the limitation of the moving trolley.

[0017] Step 2: Drive the rotating seat to rotate through the operation of the first motor. When the rotating seat rotates to the top of the vertical seat, at this time, the limiting plate moves out of the plate seat and then is clamped into the clamping groove and fixed by bolts. Drive the winding wheel to rotate through the operation of the second motor, realizing the winding and unwinding of the connecting rope, driving the lifting seat to lift and lower along the first guide rail. After the lifting is completed, drive the second air cylinder to work until the telescopic end contacts the first guide rail, realizing the fixation of the lifting seat. The limiting plate is retracted into the plate seat, and when the rotating seat rotates to one side of the vertical seat, folding and storage are realized.

[0018] Step 3: The third air cylinder contracts to drive the carriage to move. At this time, the swing arm is in a parallel state, and the airbag on the ring seat contacts the wall surface. The deformation of the airbag ensures a tight fit. The third motor works to drive the drill bit to rotate, and the third air cylinder drives the carriage to continue moving for drilling. At this time, the ring seat gradually retracts into the inner cavity of the ring cover, and at the same time, the waste chips generated by drilling are collected in the ring seat. As the ring seat moves, the retaining ring pushes the waste chips into the material pipe and drops into the collection cylinder. After the drilling is completed, at this time, the third air cylinder contracts, and at the same time, the fourth motor works to drive the swing arm to rotate upward, ensuring that the waste chips falling on the airbag fall onto the ring seat.

[0019] The beneficial effects of the present invention are as follows: The rotating seat rotates on the side seat, which can not only realize the folding and storage of the whole device after the device is used, reducing the occupied space, but also can be used in combination with the vertical seat and the rotating seat to expand the lifting range of the lifting seat, facilitating the realization of drilling work at different heights.

[0020] During drilling, the swing arm is in a parallel state, and the airbag on the ring seat contacts the wall surface. The deformation of the airbag ensures a tight fit. And when the third air cylinder drives the carriage to move for drilling, at this time, the ring seat gradually retracts into the inner cavity of the ring cover, compressing the spring to ensure that the airbag always fits the wall surface, avoiding the dust and waste chips generated by drilling from flying out. The waste chips generated by drilling are automatically collected in the ring seat. As the ring seat moves, the retaining ring pushes the waste chips into the material pipe and drops into the collection cylinder. After the drilling is completed, at this time, the third air cylinder contracts, and at the same time, the fourth motor works to drive the swing arm to rotate upward, ensuring that the waste chips falling on the airbag fall onto the ring seat, avoiding the leakage of waste chips.
