[0041] The present application provides a technical solution: a concrete drilling device for building construction, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The utility model provides a kind of drilling device, including load-bearing plate 1, drill bit 3 and support frame 11, load-bearing plate 1 is fixedly connected with support frame 11, support frame 11 is equipped with sliding slot and is slidably connected with sliding rod 2 by sliding slot, driving assembly 31 is fixedly connected on sliding rod 2, the output end of driving assembly 31 is fixedly connected with drill bit 3, first rotating groove 22 is equipped on sliding rod 2, and cooperation component is equipped in first rotating groove 22, and power mechanism for driving drill bit 3 to drill is equipped on load-bearing plate 1.

[0042] Load-bearing plate 1 of the device can be placed on the moving frame, then after confirming the position to be drilled, the device is moved to the position to be drilled, and then the device is fixedly positioned.

[0043] The moving frame and the limiting fixing mechanism are existing mechanisms, and those skilled in the art are familiar with them, so they will not be described in detail here, and they are not shown in the drawings.

[0044] By providing drill bit 3, the effect of drilling the position to be drilled is achieved, and drill bit 3 is an existing mechanism, and those skilled in the art are familiar with it, so it will not be described in detail here.

[0045] Through the cooperation of the power mechanism and the cooperation component, the sliding rod 2 reciprocatingly slides up and down, and the driving assembly 31 drives the drill bit 3 to rotate at the same time, so that the drill bit 3 reciprocatingly slides up and down when drilling, so that the drill bit 3 will be withdrawn each time it drills, so that the concrete debris can be discharged, improving the quality of drilling and avoiding the damage of the drill bit 3.

[0046] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the cooperation component includes a round block 27, a support rod 28 and a support block 29, the round block 27 is fixedly connected with the support rod 28 and the support block 29 respectively, the support rod 28 and the support block 29 are located at both ends of the round block 27 respectively, and the round block 27 is rotatably connected on the first rotating groove 22.

[0047] The power mechanism includes a driving rod 4, the support frame 11 is equipped with a sliding slot and is slidably connected with the driving rod 4 through the sliding slot, the driving rod 4 is equipped with a second rotating groove 41, the second rotating groove 41 is rotatably connected with a disc 42, the disc 42 is equipped with a sliding groove 43, and the sliding groove 43 is slidably connected with the support rod 28.

[0048] The power mechanism further includes a hollow frame 21 fixedly connected on the sliding rod 2, a sliding block 23 slidably connected on the hollow frame 21, a rotating rod 24 rotatably connected on the sliding block 23, a cooperation frame 25 fixedly connected on the rotating rod 24, a cooperation groove 26 equipped on the cooperation frame 25, and the cooperation groove 26 cooperates with the support block 29.

[0049] The power mechanism further comprises a connecting block 45 fixedly connected to the load-bearing plate 1, and an electric push rod 44 fixedly connected to the connecting block 45, with an output end of the electric push rod 44 fixedly connected to the driving rod 4. The driving rod 4 is provided with a position sensor, and the position sensor is electrically connected to the drill bit 3.

[0050] The electric push rod 44 is a PLC programmed electric push rod, so that the output end of the electric push rod 44 reciprocates. The PLC programmed electric push rod is a prior art and is well known to those skilled in the art, and thus will not be described in detail here.

[0051] When the electric push rod 44 is started, the output end of the electric push rod 44 reciprocates, and since the output end of the electric push rod 44 is fixedly connected to the driving rod 4, the driving rod 4 reciprocates, and the second rotating groove 41 on the driving rod 4 drives the disc 42 to reciprocate. Since the sliding groove 43 on the disc 42 is in sliding connection with the support rod 28 on the circular block 27, the circular block 27 and the support rod 28 drive the sliding rod 2 to reciprocate.

[0052] When the sliding rod 2 slides downward, the drill bit 3 drills a hole at a position to be drilled. When the sliding rod 2 slides upward, the drill bit 3 synchronously slides upward, so as to discharge the concrete chips, thereby improving the quality of drilling the building concrete.

[0053] By arranging the position sensor, when the driving rod 4 slides away from the electric push rod 44, the sliding rod 2 drives the drill bit 3 to slide downward. Since the position sensor is electrically connected to the drill bit 3, the rotating speed of the drill bit 3 increases, thereby improving the drilling quality. When the driving rod 4 slides toward the electric push rod 44, the sliding rod 2 drives the drill bit 3 to slide upward. Since the position sensor is electrically connected to the drill bit 3, the rotating speed of the drill bit 3 decreases, so that the concrete chips are smoothly discharged, and the hole wall is not damaged.

[0054] Referring to Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 , the support frame 11 is provided with an adjusting mechanism for automatically deepening the drilling depth.

The air inlet pipe 54 and the air outlet pipe 53 are fixedly communicated with the first piston cylinder 5. The air inlet pipe 54 and the air outlet pipe 53 are respectively located at two ends of the first piston cylinder 5. A one-way valve 55 is fixedly connected to each of the air inlet pipe 54 and the air outlet pipe 53.

[0055] The adjusting mechanism further comprises a second piston cylinder 6 fixedly connected in the hollow frame 21, a second sealing plug 62 slidably connected on the inner wall of the second piston cylinder 6, a second piston rod 61 fixedly connected on the second sealing plug 62, the second piston rod 61 being fixedly connected with the sliding block 23, the exhaust pipe 53 being fixedly communicated with the second piston cylinder 6 at the end away from the first piston cylinder 5, and a first spring 63 sleeved on the second piston rod 61, the two ends of the first spring 63 being fixedly connected with the second sealing plug 62 and the second piston cylinder 6 respectively.

[0056] When the driving rod 4 reciprocally slides, the fixed block 52 drives the first piston rod 51 and the first sealing plug 56 to reciprocally slide along the first piston cylinder 5, so that the air pressure in the first piston cylinder 5 reciprocally changes, due to the fixed connection between the fixed block 52 and the driving rod 4.

[0057] When the first piston rod 51 and the first sealing plug 56 slide along the first piston cylinder 5 to the end away from the air inlet pipe 54, the negative pressure is generated in the first piston cylinder 5 through the cooperation of the one-way valve 55, so that the air outside is sucked into the first piston cylinder 5 through the air inlet pipe 54, and when the first piston rod 51 and the first sealing plug 56 slide along the first piston cylinder 5 to the end close to the air inlet pipe 54, the high pressure is generated in the first piston cylinder 5 through the cooperation of the one-way valve 55, so that the air in the first piston cylinder 5 is discharged into the second piston cylinder 6 through the exhaust pipe 53.

[0058] Since the second piston cylinder 6 is in the sealed state at this time, when the air is discharged into the second piston cylinder 6 through the exhaust pipe 53, the second sealing plug 62 and the second piston rod 61 are pushed to the end away from the exhaust pipe 53, so that the sliding block 23 slides along the hollow frame 21 to the end close to the sliding rod 2.

[0059] When the sliding block 23 slides along the hollow frame 21 to the end close to the sliding rod 2, the rotating rod 24 thereon drives the cooperation frame 25 to slide to the end close to the sliding rod 2, and since the cooperation groove 26 on the cooperation frame 25 cooperates with the support block 29 on the circular block 27, the support block 29 drives the circular block 27 and the support rod 28 to rotate with the first rotating groove 22 as the center, so that when the driving rod 4 reciprocally slides, the circular block 27 and the support rod 28 rotate, so that when the sliding rod 2 reciprocally slides along the support rod 28, the sliding distance of the drill bit 3 driven by the sliding rod 2 is longer than the last time, so that the drilling distance is increased.

[0060] After each drilling, the drilling distance of the next time is increased, and so on, so that the drilling quality is improved, and the drill bit 3 is prevented from being damaged. Embodiment

[0063] After the drilling is completed, the hand pulling block 71 is manually pushed, so that the connecting rod 72 and the circular table 65 slide into the second piston cylinder 6, and at this time, the circular table 65 is disengaged from the circular table hole 64, and at the same time, the cooperation of the first spring 63 makes the gas in the second piston cylinder 6 discharged through the conveying pipe 66 and the nozzle 67, so that the concrete chips in the drilling hole are blown and cleaned, thereby achieving the effect of timely cleaning the drilling hole.

[0064] The circular table 65 and the circular table hole 64 are arranged, so that the gas in the second piston cylinder 6 will not overflow when the hand pulling block 71 is not manually pushed;

[0080] Start the electric push rod 44, when the output end of the electric push rod 44 reciprocatingly slides, because the output end of the electric push rod 44 is fixedly connected with the driving rod 4, so that the driving rod 4 reciprocatingly slides, the second rotating groove 41 on it drives the disc 42 to reciprocatingly slide, because the sliding groove 43 on the disc 42 is slidingly connected with the support rod 28 on the circular block 27, so that the circular block 27 and the support rod 28 drive the sliding rod 2 to reciprocatingly slide.

[0081] When the sliding rod 2 slides downward, the drill bit 3 drills the position to be drilled, when the sliding rod 2 slides upward, the drill bit 3 synchronously slides upward, thereby discharging the concrete chips, improving the quality of drilling the building concrete.

[0082] By setting the position sensor, when the driving rod 4 slides away from the end of the electric push rod 44, at this time the sliding rod 2 drives the drill bit 3 to slide downward, because the position sensor is electrically connected with the drill bit 3, so that the rotating speed of the drill bit 3 increases, improving the drilling quality, when the driving rod 4 slides towards the end close to the electric push rod 44, at this time the sliding rod 2 drives the drill bit 3 to slide upward, because the position sensor is electrically connected with the drill bit 3, so that the rotating speed of the drill bit 3 decreases, thereby the concrete chips are smoothly discharged, and the effect of not damaging the hole wall.

[0084] When the first piston rod 51 and the first sealing plug 56 slide along the first piston cylinder 5 away from the end of the air inlet pipe 54, through the cooperation of the one-way valve 55, so that the negative pressure is generated in the first piston cylinder 5, thereby the air outside is sucked into the first piston cylinder 5 through the air inlet pipe 54, when the first piston rod 51 and the first sealing plug 56 slide along the first piston cylinder 5 towards the end close to the air inlet pipe 54, through the cooperation of the one-way valve 55, so that the high pressure is generated in the first piston cylinder 5, thereby the gas in the first piston cylinder 5 is discharged into the second piston cylinder 6 through the exhaust pipe 53.

[0085] Since the second piston cylinder 6 is in a sealed state at this time, when the gas is discharged to the second piston cylinder 6 through the exhaust pipe 53, the second sealing plug 62 and the second piston rod 61 are pushed away from the end of the exhaust pipe 53, so that the sliding block 23 slides along the hollow frame 21 to the end close to the sliding rod 2.

[0086] When the sliding block 23 slides along the hollow frame 21 to the end close to the sliding rod 2, the rotating rod 24 thereon drives the matching frame 25 to slide to the end close to the sliding rod 2, and since the matching groove 26 on the matching frame 25 cooperates with the support block 29 on the round block 27, the support block 29 drives the round block 27 and the support rod 28 to rotate around the first rotating groove 22, so that when the driving rod 4 reciprocates, the sliding distance of the sliding rod 2 driven by the drill bit 3 is longer than the last time due to the rotation of the round block 27 and the support rod 28, so that the drilling distance is increased.

[0087] After each drilling, the distance of the next drilling is increased, and so on, so that the drilling quality is improved and the drill bit 3 is prevented from being damaged.

[0088] After the drilling is completed, the hand-pulling block 71 is manually pushed to make the connecting rod 72 and the circular table 65 slide into the second piston cylinder 6, and at this time the circular table 65 is disengaged from the circular table hole 64, and at the same time the cooperation of the first spring 63 makes the gas in the second piston cylinder 6 discharged through the conveying pipe 66 and the nozzle 67, so as to blow and clean the concrete chips in the drilling hole, thereby achieving the effect of timely cleaning the drilling hole.

[0089] The circular table 65 and the circular table hole 64 are arranged to prevent the gas in the second piston cylinder 6 from overflowing when the hand-pulling block 71 is not manually pushed;

[0090] The limiting groove 75 and the limiting block 74 are arranged to limit the connecting rod 72 and the circular table 65 when the hand-pulling block 71 is pushed until the limiting block 74 is located at the inner end of the connecting frame 7, and the hand-pulling block 71 is rotated to disengage the limiting block 74 from the limiting groove 75 and cooperate with the inner end of the connecting frame 7, so as to limit the connecting rod 72 and the circular table 65 until the gas in the second piston cylinder 6 is exhausted.

[0091] The second spring 73 is arranged to assist the connecting rod 72 and the circular table 65 to reset, and when the circular table 65 and the circular table hole 64 cooperate, the circular table 65 and the circular table hole 64 will not loosen.

[0092] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
