Description

Technical Field

[0001] This invention belongs to the field of drilling technology for precast concrete components, and in particular relates to a drilling device for processing precast concrete components. Background Technology

[0002] Precast concrete components, as core components in prefabricated buildings and various engineering structures, are widely used in modern construction. During the production and processing of precast concrete components, it is typically necessary to machine through holes of different specifications and locations on the surface of the components according to the process requirements of assembly connections, pipeline routing, or embedded part installation. Currently, drilling operations for precast concrete components are mainly completed using specialized mechanical drilling equipment or CNC drilling machines.

[0003] A drilling device for processing precast concrete components, disclosed in CN113977777A, includes a base, an operating table fixedly connected to the top of the base, a cavity inside the operating table, and a numbered hole evenly opened on the top of the operating table, which communicates with the cavity. A precast concrete component is placed on the top of the operating table, and the drilling operation of the precast concrete component is completed by a drill bit that moves up, down and rotates above the precast concrete component.

[0004] The aforementioned existing drilling devices have the following technical defects in actual operation:

[0005] (1) The existing concrete precast support platform is designed with a multi-hole structure to avoid the downward movement of the drill rod. This design limits the drilling position on the surface of the concrete precast. Before drilling, the concrete precast needs to be accurately positioned according to the drilling position. When the drilling position is misaligned with the hole on the surface of the support platform, the position of the concrete precast needs to be readjusted and repositioned, which reduces the efficiency of drilling the concrete precast. If the misalignment is not detected in time, the rotating drill rod will damage the support platform, increasing the wear of the drill rod and the maintenance cost of the drilling device.

[0006] (2) Most existing drilling devices only have a one-way dust suction hood above the drill bit or use open drilling. Not only is the dust suction range limited, but when the drill bit penetrates the bottom surface of the precast component, the airflow and fine dust will spread outward from the bottom avoidance area. If the bottom of the precast component is unsupported around the penetration position, the concentrated axial thrust when the drill bit penetrates will easily cause local cracking of the concrete around the bottom of the hole, affecting the flatness of the hole edge and the structural strength of the component. Summary of the Invention

[0007] The purpose of this invention is to provide a drilling device for processing precast concrete components. Through the structural design of the drive assembly, drilling assembly, lifting assembly, moving part, centering assembly and material loading assembly, the problems in the background art mentioned above are solved.

[0012] In one embodiment of the present invention, the drilling assembly further includes a motor mounting box, a motor with two output ends connected to the drill rod installed inside the motor mounting box, and a linkage sleeve fixed at the bottom of a support plate fixed on one side of the motor mounting box. The linkage sleeve is slidably sleeved on the linkage rod and its upper end passes through the support plate.

[0013] Preferably, the dust extraction unit includes a hollow guide hood located below the motor mounting box. A corrugated pipe communicating with the inner cavity of the hollow guide hood is connected between the hollow guide hood and the motor mounting box. The corrugated pipe is concentrically mounted on the outside of the drill rod. Limiting guide rods that are slidably connected to the side wall of the motor mounting box are fixed on opposite sides of the hollow guide hood. An air inlet pipe is connected to the periphery of the hollow guide hood.

[0014] In one embodiment of the present invention, the movable part includes a movable seat, and a movable channel is provided on the top of the movable seat along its length direction; the centering component further includes a movable frame sleeved on the top of the movable seat and rollingly engaged with the movable seat through guide wheels, a linkage rod fixed on one side of the top of the movable frame, and a dust discharge pipe passing through the movable channel and fixedly connected to the movable frame.

[0015] In one embodiment of the present invention, the lifting assembly includes a lifting platform slidably disposed between vertical guide grooves, the top of the lifting platform having a rectangular opening and an annular guide frame, the rectangular opening being located inside the annular guide frame, and guide roller cavities being opened on opposite sides of the bottom of the lifting platform; the movable seat is sleeved on the top of the annular guide frame and rolls with the annular guide frame through guide wheels.

[0016] In the above scheme, a turntable connected to one output end of a motor is rotatably provided inside the circular cavity. A bearing guide roller is provided at an eccentric position on the side of the turntable near the lifting component. The bearing guide roller is slidably fitted inside the corresponding guide roller cavity. An arc-shaped guide groove coaxial with the bearing guide roller is provided on the side of the turntable opposite to the bearing guide roller. An eccentric guide groove is connected to the end of the arc-shaped guide groove.

[0017] Optionally, the material loading assembly further includes a material loading platform connected to the inner side of the drive frame via a rotating shaft. The drilling opening is located at the center of the top of the material loading platform. A motor three for controlling the rotation of the material loading platform is installed on one side of the drive frame. The drilling opening is symmetrically provided with limiting channels on both sides. The material loading platform is symmetrically provided with reinforcing channels on both sides. The top of the material loading platform is symmetrically provided with positioning component one that plugs into the limiting channel. The bottom of the material loading platform is symmetrically provided with positioning component two that plugs into the limiting channel. Positioning component one and the corresponding positioning component two are connected by bolt fasteners.

[0018] In one implementation of the present invention, the drive frame is provided with reinforcing components on both opposite sides; wherein, the reinforcing components include a support frame slidably disposed between the limiting guide rails, a stepped guide wheel mounted on the support frame via a rotating shaft, the small diameter section of the stepped guide wheel fitting into an arc-shaped guide groove or an eccentric guide groove, and the large diameter section of the stepped guide wheel fitting into a guide channel; symmetrical inclined guide frames are provided above the support frame, a spherical pushing member is fixed at the top of the support frame and fits against the bottom inclined surface of the inclined guide frame, a reinforcing rod is fixed on one side of the inclined guide frame and slidably fitted into a through hole on the surface of the drive frame, and a support rod is fixed on the opposite two outer side walls of the drive frame and slidably penetrates the inclined guide frame, and an elastic member connecting the inclined guide frame and the drive frame is sleeved on the support rod.

[0019] The present invention has the following beneficial effects: 1. The present invention sets a drilling port on the material loading component used to support precast concrete components. During the process of adjusting the drilling position of the drilling component and the centering component by using the drilling control mechanism, the open space of the drilling port facilitates the multi-directional adjustment of the bucket-shaped support cover. The position of the bucket-shaped support cover inside the drilling port can be flexibly adjusted to meet the drilling operation requirements of different positions on the surface of the precast concrete components. It does not have the technical defects of low positioning efficiency and easy damage to the multi-hole support platform caused by the existing multi-hole support platform structure.

[0020] 2. During the drilling operation, the corrugated pipe between the motor mounting box and the hollow guide shroud is in a compressed state. The bucket-shaped support shroud provides stable support to the bottom of the precast concrete component at the drilling position, thus providing effective support for the drilling point. This avoids the problem of localized cracking of the concrete around the bottom of the hole caused by the concentrated axial thrust when the drill rod penetrates. At the same time, the synergistic effect of the elastically compressible corrugated pipe and the bucket-shaped support shroud can prevent dust generated during the drilling process from escaping and polluting the environment.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figures 1 to 12The present invention is a drilling device for processing precast concrete components, comprising a drive assembly 1, a lifting assembly 3, a centering assembly 5, and a loading assembly 6; a drilling assembly 2 is provided above the drive assembly 1, and a drilling control mechanism for controlling its lifting and translation is provided above the drilling assembly 2; the lifting assembly 3 is lifted and installed inside the drive assembly 1, and its top is provided with a moving part 4 that slides along the X-axis; the centering assembly 5 is slidably disposed on the moving part 4 along the Y-axis and is concentrically arranged with the drilling assembly 2.

[0038] The material loading assembly 6 is installed inside the drive assembly 1 and above the centering assembly 5, and is used for supporting and positioning the precast concrete component 7; the drilling assembly 2 includes a drill rod and a dust extraction part that is concentrically sleeved on the outside of the drill rod and can be elastically compressed; the centering assembly 5 includes a bucket-shaped support cover 8 coaxial with the drill rod and a linkage rod 9 that slides vertically through the drilling assembly 2, and a dust discharge pipe 10 is fixed at the bottom of the bucket-shaped support cover 8. Both the dust extraction part and the dust discharge pipe 10 are connected to the dust removal equipment; the material loading assembly 6 includes a drilling port 11. When the bottom of the dust extraction part presses against the top of the precast concrete component 7, the bucket-shaped support cover 8 is controlled to pass through the drilling port 11 and support the bottom of the precast concrete component 7. The dust is extracted in situ through the dust extraction part and the dust discharge pipe 10 throughout the drilling process.

[0039] The specific structure of the driving component 1 in this invention is as follows: Figure 4 As shown, the drive assembly 1 includes a drive carrier 12, on which motors 13 are mounted on both outer side walls of the drive carrier 12, and on both inner side walls of the drive carrier 12, circular cavities 14 are provided, with the circular cavities 14 and motors 13 being coaxially arranged.

[0040] Vertically arranged limiting guide rails 15 are installed on both outer side walls of the drive frame 12. A guide channel 16 is provided between the two limiting guide rails 15 on the same side, which passes through the circular cavity 14. The guide channel 16 is arranged parallel to the limiting guide rails 15. Vertical guide grooves 17 are provided on both inner side walls of the drive frame 12.

[0041] The specific structure of the drilling assembly 2 in this invention is as follows: Figure 12 As shown, the drilling assembly 2 also includes a motor mounting box 18. The output end of the second motor, mounted inside the motor mounting box 18, is connected to the drill rod. A linkage sleeve 19 is fixed to the bottom of a support plate fixed to one side of the motor mounting box 18. It should be noted that the linkage sleeve 19 is always fitted onto the linkage rod 9, and the two will not detach. Furthermore, during the process of controlling the lowering of the motor mounting box 18 for drilling, the linkage sleeve 19 will never contact the moving frame 26. Figure 3 and Figure 12The relative position of the linkage sleeve 19 and the linkage rod 9 is such that the bottom of the hollow guide shroud 20 just touches the top of the precast concrete component 7. The linkage sleeve 19 is slidably sleeved on the linkage rod 9, and its upper end passes through the support plate. Specifically, the drilling control mechanism set above the motor mounting box 18 includes a traveling seat that can move automatically along the X and Y axes. The output end of the lifting part (such as an electric actuator or hydraulic rod) installed on the traveling seat is connected to the top cover of the motor mounting box 18. The movement process of the traveling seat is set by the control system, which is a prior art technique.

[0042] It should be noted that the motor mounting box 18 is connected to the single-sided linkage rod 9 through the support plate and the linkage sleeve 19. The support plate, the linkage sleeve 19 and the single-sided linkage rod 9 are all made of high-strength material. This high-strength linkage structure can effectively offset the deflection torque and prevent the moving frame 26 from sliding and jamming on the moving seat 24 due to uneven force.

[0043] The specific structure of the dust extraction unit in this invention is as follows: Figure 12 As shown, the dust extraction unit includes a hollow guide hood 20 located below the motor mounting box 18. A corrugated pipe 21 communicating with the inner cavity of the hollow guide hood 20 is connected between the hollow guide hood 20 and the motor mounting box 18. The corrugated pipe 21 is concentrically located on the outside of the drill rod. Limiting guide rods 22 that are slidably connected to the side walls of the motor mounting box 18 are fixed on opposite sides of the hollow guide hood 20. Through the joint connection of the limiting guide rods 22 and the corrugated pipe 21, the relative position between the hollow guide hood 20 and the motor mounting box 18 is fixed in the initial state. The top of the limiting guide rods 22 is supported by the top of the sliding groove on the motor mounting box 18. An air inlet pipe 23 is connected to the periphery of the hollow guide hood 20.

[0044] The specific structure of the moving part 4 in this invention is as follows: Figure 3 and Figure 11 As shown, the moving part 4 includes a moving base 24, and a moving channel 25 is provided on the top of the moving base 24 along its length direction; the centering component 5 also includes a moving frame 26 sleeved on the top of the moving base 24 and rollingly engaged with the moving base 24 through guide wheels. The guide wheels on both sides of the bottom of the moving frame 26 are engaged in the guide wheel grooves on the side wall of the moving base 24. The linkage rod 9 is fixed on one side of the top of the moving frame 26. The dust exhaust pipe 10 passes through the moving channel 25 and is fixedly connected to the moving frame 26. When the lifting component 3 is at its lowest position, the bottom of the dust exhaust pipe 10 on it is also higher than the bottom of the drive frame 12. The dust exhaust pipe 10 and the hollow guide hood 20 are both connected to the dust removal equipment through external hoses. During the drilling operation, each external hose will not be interfered with by the movement of each lifting component.

[0045] The specific structure of the lifting component 3 in this invention is as follows: Figure 7 and Figure 8As shown, the lifting assembly 3 includes a lifting platform 27 slidably disposed between the vertical guide grooves 17. The top of the lifting platform 27 is provided with a rectangular opening 28 and an annular guide frame 29. The rectangular opening 28 is located inside the annular guide frame 29. Guide roller cavities 30 are opened on opposite sides of the bottom of the lifting platform 27. The movable seat 24 is sleeved on the top of the annular guide frame 29 and rolls with the annular guide frame 29 through guide wheels. Specifically, the guide wheels on both sides of the bottom of the movable seat 24 are fitted into the guide wheel grooves on the side wall of the annular guide frame 29.

[0046] like Figure 1 , Figure 3 and Figure 9 As shown, a turntable 31 connected to the output end of motor 13 is rotatably installed inside the circular cavity 14. The motors 13 on both sides are linked for control. A bearing guide roller 32 is provided at the eccentric position of the turntable 31 near the lifting assembly 3. The bearing guide roller 32 is slidably fitted inside the corresponding guide roller cavity 30. An arc-shaped guide groove 33 coaxial with the bearing guide roller 32 is provided on the side of the turntable 31 opposite to the bearing guide roller 32. An eccentric guide groove 34 is connected to the end of the arc-shaped guide groove 33. The turntables 31 on both sides achieve the smooth up and down movement of the lifting assembly 3 by rotating synchronously.

[0047] In the initial state, the bearing guide rollers 32 on both sides are at their lowest positions, and the bearing guide rollers 32 cooperate with the guide roller cavity 30 to support the lifting platform 27. When drilling is required on the precast concrete component 7, the traveling seat is controlled to move to the required position according to the drilling position requirements through the drilling control mechanism. The traveling seat drives the drilling assembly 2 to move along the same trajectory through the lifting part on it. The drilling assembly 2 drives the centering assembly 5 to move to the required position with the cooperation of the linkage sleeve 19 and the linkage rod 9. At this time, the drill rod and the bucket-shaped support cover 8 move synchronously to the required drilling position.

[0048] Simultaneously starting the motors on both sides 13 drives the turntable 31 to rotate 180° counterclockwise (e.g.) Figure 3 As shown), the bearing guide roller 32, which rotates synchronously with the turntable 31, moves to its highest position, i.e. Figure 3 At the indicated position, during this process, the lifting assembly 3 is driven to move upward to the set position by the pushing action of the bearing guide roller 32 on the guide roller cavity 30. The rubber pad on the top of the bucket-shaped support cover 8 is flush with the top surface of the material loading assembly 6 (i.e., the top surface of the material loading platform 35). The precast concrete component 7 is placed on the top of the material loading assembly 6 and circumferentially positioned. At this time, the rubber pad on the top of the bucket-shaped support cover 8 on the lifting assembly 3 is tightly pressed against the bottom of the precast concrete component 7 by the drilling operation port 11. Then, the drilling assembly 2 is controlled to move downward by the lifting part on the drilling control mechanism. After the rubber pad at the bottom of the hollow guide cover 20 is attached to the top of the precast concrete component 7, the dust removal equipment is started so that the outside air enters the inner cavity of the hollow guide cover 20 along the air inlet pipe 23, and then enters the dust removal equipment through the hollow guide cover 20 along the external hose.

[0049] Next, the secondary drive motor is started to rotate the drill rod. While the drill rod rotates, it is gradually lowered via a lifting mechanism until it penetrates the precast concrete component 7, completing the drilling operation. Dust generated during the initial drilling phase is discharged into the dust collection equipment via airflow through the hollow guide hood 20. At the moment the drill rod penetrates the bottom of the precast concrete component 7, the dust generated during drilling enters the bucket-shaped support hood 8. The dust entering the bucket-shaped support hood 8 is then discharged into the dust collection system along the dust discharge pipe 10 and the corresponding external hose under the action of airflow. In the equipment, during the drilling operation when the drill rod rotates and descends, the corrugated pipe 21 between the motor mounting box 18 and the hollow guide shroud 20 is in a compressed state. Through the stable support of the bottom of the precast concrete component 7 at the drilling position by the bucket-shaped support cover 8, an effective support is formed for the drilling point. This can avoid the problem of local cracking of the concrete around the bottom of the hole caused by the concentrated axial thrust when the drill rod penetrates. At the same time, through the synergistic effect of the elastically compressible corrugated pipe 21 and the bucket-shaped support cover 8, the dust generated during the drilling process can be prevented from escaping and polluting the environment.

[0050] This invention addresses these shortcomings by providing a drilling opening 11 on the material-carrying assembly 6 that supports the precast concrete component 7. During the drilling process, the drilling control mechanism adjusts the drilling positions of the drilling assembly 2 and the centering assembly 5. The open space of the drilling opening 11 facilitates multi-directional adjustment of the bucket-shaped support cover 8, allowing for flexible adjustment of its position within the opening 11 to meet the drilling needs at different locations on the surface of the precast concrete component 7. Compared to existing multi-hole support structures, which suffer from the drawback of requiring precise positioning of the precast concrete component before drilling, necessitating readjustment and repositioning when misalignment occurs, thus reducing drilling efficiency, and potentially damaging the support platform due to the wear and tear on the drill rod if misalignment is not detected promptly, leading to increased maintenance costs, this invention effectively solves these shortcomings through the combined action of the drilling opening 11 and the bucket-shaped support cover 8.

[0051] After the drilling operation is completed, the drilling assembly 2 is first moved upwards by the drilling control mechanism to complete the reset, and the positioning lock on the precast concrete component 7 is released and it is removed. Then, the motors 13 on both sides are started to drive the turntable 31 to rotate 180° clockwise (e.g., Figure 3 As shown), the bearing guide roller 32, which rotates synchronously with the turntable 31, moves to the lowest position (that is, the turntable 31 and the bearing guide roller 32 on it are reset). During this process, the lifting assembly 3 is driven to move down to the initial position by the weight of the lifting assembly 3 and the supporting effect of the bearing guide roller 32 on the guide roller cavity 30. The centering assembly 5 moves down synchronously with the lifting assembly 3 to complete the reset.

[0052] Example 2, based on Example 1, such as Figure 5 , Figure 6 and Figure 10 As shown, the material loading assembly 6 also includes a material loading platform 35 connected to the inner side of the drive frame 12 via a rotating shaft. The drilling port 11 is located at the top center of the material loading platform 35. A motor 36 for controlling the rotation of the material loading platform 35 is installed on one side of the drive frame 12. During the drilling operation, the precast concrete component 7 is supported by the material loading platform 35.

[0053] The drilling opening 11 is symmetrically provided with limiting channels 37 on both sides. The loading platform 35 is symmetrically provided with reinforcing channels 38 on both sides. The axis of the reinforcing channel 38 is on the same horizontal plane as the axis of the motor 36, ensuring that the reinforcing channel 38 is still at the same height after the loading platform 35 is rotated 180°. The top of the loading platform 35 is symmetrically provided with positioning parts 1 39 that are inserted into the limiting channels 37. The bottom of the loading platform 35 is symmetrically provided with positioning parts 2 40 that are inserted into the limiting channels 37. Positioning parts 1 39 and corresponding positioning parts 2 40 are connected by bolt fasteners. The positioning parts 1 39 and positioning parts 2 40 on the upper and lower sides of the loading platform 35 are different in size, which can meet the drilling operations of two different sizes of precast concrete parts 7.

[0054] The specific structure of the reinforcing component 41 in this invention is as follows: Figure 1 and Figure 10 As shown, the drive frame 12 is provided with reinforcing components 41 on both sides; wherein, the reinforcing component 41 includes a support frame 42 slidably disposed between the limiting guide rails 15, and a stepped guide wheel 43 is mounted on the support frame 42 through a rotating shaft. The small diameter section of the stepped guide wheel 43 is fitted in the arc-shaped guide groove 33 or the eccentric guide groove 34, and the large diameter section of the stepped guide wheel 43 is fitted in the guide channel 16. In the initial state, the small diameter section of the stepped guide wheel 43 is fitted in the end of the eccentric guide groove 34 near the axis, and the large diameter section of the stepped guide wheel 43 is fitted in the bottom of the guide channel 16.

[0055] A symmetrical inclined guide frame 44 is provided above the support frame 42. A spherical pusher 45 is fixed at the top of the support frame 42 and fits against the bottom inclined surface of the inclined guide frame 44. A reinforcing rod 47 is fixed on one side of the inclined guide frame 44 and slides into the through hole 46 on the surface of the drive carrier 12. The reinforcing rod 47 is always fitted into the through hole 46. Support rods 48 that slide through the inclined guide frame 44 are fixed on the two opposite outer walls of the drive carrier 12. An elastic element 49 is sleeved on the support rod 48 and connects the inclined guide frame 44 and the drive carrier 12. In this embodiment, a return spring is used.

[0056] In the initial state, the bearing guide roller 32 is at its lowest position, the small-diameter section of the stepped guide wheel 43 fits into the end of the eccentric guide groove 34 near the axis, the large-diameter section of the stepped guide wheel 43 fits into the bottom of the guide channel 16, the top of the spherical pusher 45 abuts against the bottom of the inclined surface of the inclined guide frame 44, and the reinforcing rod 47 is separated from the reinforcing groove 38 on the loading platform 35. During the counterclockwise rotation of the control turntable 31 (e.g. Figure 3 As shown), the small-diameter section of the stepped guide wheel 43 rolls along the eccentric guide groove 34 in a direction away from the axis of the turntable 31. The eccentric guide groove 34 pushes the small-diameter section of the stepped guide wheel 43, causing the large-diameter section of the stepped guide wheel 43 to roll upwards along the guide channel 16. The support frame 42, which moves upwards synchronously with the stepped guide wheel 43, drives the spherical pressing member 45 to move upwards. The spherical pressing member 45 presses against the inclined surface of the inclined guide frame 44, causing the inclined guide frame 44 to gradually approach the drive frame 12 and compress the elastic member 49. When the small-diameter section of the stepped guide wheel 43 rolls along the eccentric guide groove 34 and just enters the arc-shaped guide groove 33, the support frame 42 moves up to the highest position and stops moving upward. Each reinforcing rod 47 is horizontally inserted into the corresponding reinforcing groove 38. Through the self-locking action of the motor 36 on the loading platform 35 and the locking position of the reinforcing rods 47 and the reinforcing groove 38, the stable placement of the precast concrete component 7 on the top of the loading platform 35 can be ensured, so as to avoid the loading platform 35 shaking during the drilling operation. As the turntable 31 continues to rotate counterclockwise, since the small-diameter section of the stepped guide wheel 43 rolls along the arc-shaped guide groove 33, the support frame 42 remains stable at the highest position and stops moving upward, while the turntable 31 can continue to rotate counterclockwise until the turntable 31 completes a 180° counterclockwise rotation. The bearing guide roller 32, which rotates synchronously with the turntable 31, moves to the highest position. After the precast concrete component 7 is positioned and fixed on the top of the loading platform 35, the drilling operation can begin. When drilling is required for another size of precast concrete component 7, the loading platform 35 can be rotated 180° by motor 36 in the initial state, and the positioning of the precast concrete component 7 around the perimeter can be achieved by positioning components 2 40 on both sides.
