Description

Technical Field

[0001] The invention relates to the technical field of suspended ceiling punching, in particular to an indoor suspended ceiling punching device. Background Art

[0002] At present, indoor projects generally use light steel keel gypsum board, aluminum board, mineral wool board and other suspended ceilings. These suspended ceilings need to fix the keel on the hanging rod. Many buildings are built without pre-embedded iron parts for hanging rods, so during indoor decoration, the ceiling hanging rods must be fixed to the floor with expansion screws. First, use an impact drill to drill a hole with a diameter slightly larger than the diameter of the expansion bolt, then weld the expansion screw firmly at one end of the hanging rod, tighten it into the hole, and squeeze the expansion inner thread hole open.

The ceiling drilling operation has the advantages of convenient construction, high efficiency, high safety and small impact on the environment. The above-mentioned related technologies have the following defects: when the drill rod is drilling, some dust generated by the drilling will leak out from between the drill rod and the drilled hole, but some dust will remain in the hole. In the subsequent drilling, the generated dust will cause friction with the inner wall of the hole, which can easily cause the drilled hole to have a larger diameter and lower precision. For this reason, an indoor ceiling drilling device is proposed. Summary of the invention

[0016] 1. The present invention controls the drilling structure to be continuously separated from the drilled hole during drilling by arranging components such as an outer riser, an inner bend pipe and an outer bend pipe. After the drill rod is separated from the hole each time, the air ring inflates the inner part of the outer bend pipe through the outer riser and the inner bend pipe, and the gas filled in the outer bend pipe is ejected from the upper end of the outer bend pipe. The upward airflow blows into the hole to blow out the dust in the hole, thereby reducing the influence of dust on the hole accuracy when the drilling structure enters the hole for drilling again.

[0017] 2. The present invention provides components such as threaded rods, meshing gears, reciprocating frames, rotating frames and reciprocating screws, so that when the driving gear rotates, the meshing gears and the internal gears are driven to rotate synchronously. During the rotation of the internal gear, the rotating frame is driven to reciprocate up and down by meshing with the reciprocating screw. When the drilling structure moves up and down synchronously with the rotating frame, it is reciprocated and disengaged from the drilled hole. At the same time, the rotation of the driving gear drives the meshing gears to rotate. The rotating meshing gears are engaged with the threaded rods, gradually driving the reciprocating frame to move upward relative to the control frame, so that after the drilling structure follows the rotating frame to move up and down each time, the depth of the drilling structure drilling into the hole again increases. During the drilling of the hole, the drilling structure is disengaged from the hole for multiple times, so as to prevent dust from remaining in the hole and affecting the drilling accuracy.

[0018] 3. The present invention provides components such as a vertical blocking cylinder, a double-slope frame, a force-bearing frame and a horizontal blocking cylinder. Before the breathable top cylinder contacts the wall to be drilled, the breathable top cylinder drives the breathable hole A on the surface of the inner bent tube to be located inside the vertical blocking cylinder, and the vertical blocking cylinder blocks the breathable hole A to prevent the through-hole structure of the outer bent tube from spraying air outwards and causing dust leakage before the breathable top cylinder contacts the wall. When the bottom cover drives the drilling structure to move upwards to drill a hole, the double-slope frame is driven upwards relative to the breathable top cylinder by the vertical elastic telescopic rod. In the force-bearing frame pushed by the inclined surface of the double-slope frame, the two outer bent tubes gradually move away from each other, driving the outer bent tube to gradually misalign with the hole. After the two outer bent tubes move away from a certain distance, the outer bent tube drives the horizontal blocking cylinder to gradually block the breathable hole B on the surface of the inner bent tube, so that when the drilling structure drills into the hole, the upper end of the outer bent tube does not spray air outwards, preventing the outer bent tube from blowing dust into the hole again when spraying air.

[0031] The position control structure 5 includes a power rotating base frame 51 and a control frame 52. The power rotating base frame 51 is rotatably connected to the device support base 1. One end of the power rotating base frame 51 is connected to the motor. Two power telescopic rods 53 are fixed to the bottom surface of the control frame 52. The power rotating base frame 51 can control the angle of the power telescopic rod 53 relative to the device support base 1 by rotation.

Two round rods 54 are fixed to the bottom surface of the reciprocating frame 55. The upper ends of the two power telescopic rods 53 are respectively slidably sleeved on the outer surfaces of the two round rods 54. A meshing gear 56 is rotatably inserted at the right end of the reciprocating frame 55. A threaded rod 57 is threadedly penetrated at the axis of the meshing gear 56. The lower end of the threaded rod 57 is fixed to the control frame 52. A driving gear 58 is meshed on the left side of the meshing gear 56. The lower end of the driving gear 58 rotates and penetrates the upper surface of the reciprocating frame 55. The inner gear 59 has a thread that penetrates the reciprocating screw rod 510 at its axis. The inner gear 59 moves back and forth up and down by meshing with the reciprocating screw rod 510. The reciprocating frame 55 is rotatably sleeved on the outer surface of the reciprocating screw rod 510. A rotating frame 511 is fixed to the upper end of the reciprocating screw rod 510. When the driving gear 58 rotates, it drives the meshing gear 56 and the inner gear 59 to rotate synchronously. During the rotation of the inner gear 59, it meshes with the reciprocating screw rod 510 to drive the rotating frame 511 to move back and forth up and down. When the drilling structure 7 moves up and down synchronously with the rotating frame 511, it reciprocates and disengages from the drilled hole. At the same time, the driving gear 58 rotates and drives the meshing gear 56 to rotate. The rotating meshing gear 56 meshes with the threaded rod 57, gradually driving the reciprocating frame 55 to move upward relative to the control frame 52, so that after the drilling structure 7 follows the rotating frame 511 to move up and down each time, the depth of the drilling structure 7 drilling into the hole again increases, and the drilling structure 7 is separated from the hole many times during the drilling of the hole.

[0032] A longitudinal rod 513 is fixed to the left end of the rotating frame 511, and a connecting shaft plate 512 is rotatably sleeved on the outer surface of the longitudinal rod 513.

Two vertical rods 517 are fixed to the bottom surface of the rotating frame 511. The reciprocating frame 55 is slidably sleeved on the outer surfaces of the two vertical rods 517. When the rotating frame 511 moves up and down, the vertical rods 517 are driven to slide inside the reciprocating frame 55, so that the reciprocating frame 55 will not be misplaced when it moves relative to the rotating frame 511. A rotating motor 518 is fixed to the bottom surface of the reciprocating frame 55, and the output end of the rotating motor 518 is coaxially fixed with the driving gear 58.

The worm 5142 is fixed to the output end of the torque motor 5143, and the worm gear 5141 is meshed with the worm gear 5142. The worm gear 5141 is coaxially fixed to the connecting shaft plate 512, and the torque motor 5143 can control the angle of the bottom cover 2 through the meshing of the worm gear 5142 and the worm gear 5141.

The air pump 42 is connected and installed with the pressure valve pipe 41. The pressure valve pipe 41 penetrates and is installed on the bottom surface of the bottom cover 2. The upper end of the pressure valve pipe 41 is connected and installed with the bottom surface of the air ring 3. A pressure valve is installed on the surface of the pressure valve pipe 41. When the pressure in the air ring 3 is too high, the pressure valve can exhaust and relieve pressure.

[0035] A drilling structure 7 is provided at the axis of the air ring 3, and the drilling structure 7 is installed on the inner bottom wall of the bottom cover 2. Two external vertical pipes 8 are installed on the upper surface of the air ring 3. An inner bent pipe 10 is slidably inserted into the upper end of the external vertical pipe 8. The inner bent pipe 10 is fixed to the inner wall of the breathable top tube 6 on one side away from the axis of the bottom cover 2, and an outer bent pipe 9 is slidably sleeved on the end of the inner bent pipe 10 close to the axis of the bottom cover 2. The end of the outer bent pipe 9 close to the axis of the bottom cover 2 is vertically bent upwards, and a hole-like structure is opened on the upper end of the outer bent pipe 9.

[0036] An air hole A11 is provided on the circumferential side surface of one end of the inner bend pipe 10 located inside the outer vertical pipe 8, an air hole B12 is provided on one end of the inner bend pipe 10 located inside the outer bend pipe 9, a horizontal elastic telescopic rod 13 is fixed to one end of the inner bend pipe 10 located inside the outer bend pipe 9, the other end of the horizontal elastic telescopic rod 13 is connected to the inner wall of the outer bend pipe 9, a vertical blocking cylinder 14 is slidably sleeved on one end of the inner bend pipe 10 located inside the outer vertical pipe 8, the vertical blocking cylinder 14 is fixedly inserted into the outer vertical pipe 8, a horizontal blocking cylinder 15 is fixedly inserted at the lower end of the outer bend pipe 9, the horizontal elastic telescopic rod 13 is located on the inner side of the horizontal blocking cylinder 15, before the ventilating top cylinder 6 contacts the wall, the ventilating top cylinder 6 drives the ventilating hole A11 to be located inside the vertical blocking cylinder 14 through the inner bend pipe 10, so that the vertical blocking cylinder 14 blocks the ventilating hole A11 to prevent the through-hole structure of the outer bend pipe 9 from spraying outwards before the ventilating top cylinder 6 contacts the wall, causing dust leakage.

[0037] The interior of the vertical sealing tube 14 is matched with the lower end of the inner bend pipe 10, the lower end of the inner bend pipe 10 is a vertical end, the upper end of the inner bend pipe 10 is a horizontal end, the lower end of the outer bend pipe 9 is a horizontal end, the upper end of the outer bend pipe 9 is a vertical end, the horizontal end of the inner bend pipe 10 is matched with the inner wall of the horizontal sealing tube 15, the upper end of the outer bend pipe 9 is a pointed end, and the outer bend pipe 9 is a semicircular structure.

A vertical elastic telescopic rod 17 is fixed to the bottom surface of the double inclined plane frames 16. The lower end of the vertical elastic telescopic rod 17 is fixed to the inner bottom wall of the bottom cover 2. A force frame 18 is arranged above each double inclined plane frame 16 and on both sides of the left and right sides of the drilling structure 7. The left and right ends of the upper surface of the double inclined plane frame 16 are inclined planes symmetrical to the axis of the bottom cover 2. When the bottom cover 2 drives the drilling structure 7 to move upward to drill a hole, the double inclined plane frame 16 is driven by the vertical elastic telescopic rod 17 to move upward relative to the ventilated top tube 6. 6 pushes the force-bearing frame 18, and the two outer bends 9 gradually move away from each other, driving the outer bends 9 to gradually be misaligned with the hole. After the two outer bends 9 move away from a certain distance, the outer bends 9 drive the horizontal blocking cylinder 15 to gradually block the air vents B12 on the surface of the inner bend 10, so that when the drilling structure 7 drills into the hole, the upper end of the outer bend 9 does not spray outward, preventing the outer bend 9 from blowing dust into the hole again when spraying. The two double-bevel frames 16 are symmetrically distributed about the axis of the bottom cover 2, and the two outer bends 9 are symmetrically distributed about the axis of the bottom cover 2. The force-bearing frame 18 is fixed to the adjacent outer bends 9.

[0039] The working principle is: when drilling is required, the control device supports the base 1 to move below the position to be drilled, and then controls the breathable top tube 6 to contact the top wall surface, and controls the drilling structure 7 to continuously separate from the drilled hole during drilling. After the drill rod separates from the hole each time, the air ring 3 inflates the outer curved pipe 9 through the outer riser 8 and the inner curved pipe 10, and the gas filled in the outer curved pipe 9 is ejected from the upper end of the outer curved pipe 9, and the upward airflow blows into the hole to blow out the dust in the hole, thereby reducing the amount of dust in the hole when the drilling structure 7 enters the hole for drilling again, thereby reducing the influence of dust on the drilling accuracy during drilling.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
