Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a drilling system and method for medium and high-rise buildings. Background Technology

[0002] In the fields of building construction and interior decoration, it is often necessary to drill holes in the beams or ceilings of mid- to high-rise buildings (3-10 meters high) to secure mounting brackets for water, electricity, and HVAC pipes. Currently, this type of drilling is mainly done manually, which presents the following technical challenges: (1) Workers need to climb ladders, scaffolding or mobile lifting work platforms to work at heights, which poses a great risk of falling and makes it difficult to guarantee personal safety.

[0003] (2) When using a mobile vehicle with a lifting frame, each time a drilling point is completed and the vehicle needs to be moved to the next position, the lifting frame must be lowered first, and then raised again after the vehicle is moved into place. The workers have to climb up repeatedly, which is cumbersome and results in low overall drilling efficiency.

[0004] (3) The location of the holes is usually determined manually by measuring and marking with a tape measure or ruler. This is not only time-consuming and laborious, but also prone to measurement errors, which affect the accurate installation of the subsequent mounting bracket.

[0005] Therefore, there is an urgent need for an automated, precise, and safe drilling system and method for mid- to high-rise buildings to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] Design a drilling system for medium and high-rise buildings, including a base, with self-locking casters at the bottom of the base, a gantry bracket at the top of the base, a lifting device at the middle of the upper surface of the base, the lifting device extending upward through the gantry bracket, a working platform connected to the top of the lifting device, and a longitudinal moving mechanism, a transverse moving mechanism, a rotating mechanism, and a drilling mechanism sequentially connected above the working platform, with support mechanisms on both sides of the drilling mechanism; The drilling mechanism includes a drilling motor, a mounting block coaxially connected to the drilling motor, a fixed block movably connected to the mounting block, and a drill rod fixedly connected to the mounting block. An embedding groove is provided on one end of the mounting block near the fixed block. A limit ring is fixedly fitted on the fixed block. Multiple locking blocks are fixed on the outer circumferential surface of the mounting block. Bolts are provided on the locking blocks. A U-shaped locking block corresponding to and cooperating with the locking block is provided on the outside of the limit ring. When the mounting block and the fixed block are fixed, the locking block is engaged with the locking block and fixed by the bolts.

[0008] Preferably, both the longitudinal moving mechanism and the lateral moving mechanism are screw and nut structures, and guide rods are provided on both sides of the screw.

[0009] Preferably, the rotating structure includes a rotating shaft on a transverse moving mechanism, a driven bevel gear connected to the rotating shaft, and a main bevel gear meshing with the driven bevel gear. The main bevel gear is driven by a rotary motor. A mounting seat is provided on the top of the rotating shaft, and the drilling mechanism is provided on the mounting seat.

[0010] Preferably, the support mechanism includes an L-shaped movable frame and a top plate located at the end of the movable frame, the movable frame being driven to move by a screw and nut structure.

[0011] Preferably, the lifting mechanism includes a fixed sleeve mounted on the base, the top of the fixed sleeve extending above the gantry bracket, and a lifting rod movably mounted inside the fixed sleeve. The working platform is located on the top of the lifting rod, and teeth are provided on one side of the lifting rod. Gears that mesh with the teeth are provided inside the fixed sleeve. The gears are fixed to the inner walls on both sides of the sleeve via a rotating shaft. A lifting motor is provided on the outer side of the sleeve, and the output shaft of the lifting motor is coaxially connected to the rotating shaft.

[0012] Preferably, a pusher frame is connected to one side of the base, and the pusher frame and the gantry bracket are fixedly connected by a reinforcing rod.

[0013] Preferably, it also includes a laser positioning device and a controller. The laser positioning device includes at least one crosshair laser module, which is fixedly mounted on a fixed block and emits laser light in a horizontal direction. It is used to project a crosshair spot onto the side wall of the top beam, and the center of the crosshair spot coincides with the projection of the drill rod axis onto the side wall plane of the top beam. The controller is electrically connected to the drilling motor, the lifting motor, the drive motor of the longitudinal moving mechanism, the drive motor of the lateral moving mechanism, the drive motor of the support mechanism, and the rotary motor.

[0014] Preferably, it further includes a position detection device electrically connected to the controller, the position detection device including a first sensor for detecting the rising height of the lifting rod and a second sensor for detecting the number of rotations of the drilling motor.

[0015] A drilling method, implemented based on a drilling system for medium and high-rise buildings, includes the following steps: S1: Parameter setting; First, set the drilling depth and lifting height values ​​through the controller's input unit; S2: Equipment in position; push the base to the working area so that the drill rod is horizontal and pointing towards the side wall of the top beam; S3: Automatic lifting; Start the lifting motor, the lifting rod drives the work platform to rise, when the position detection device reports that the lifting height value set in step S1 has been reached, the controller automatically cuts off the power to the lifting motor, so that the laser module of the laser positioning device rises to the same height as the preset drilling point. S4: Laser coarse positioning; turn on the laser positioning device so that the horizontally emitted crosshair laser module projects a crosshair spot on the side wall of the top beam, and push the base so that the center of the crosshair spot is aligned with the preset drilling point on the side wall. S5: Positioning and fine-tuning; If the drill rod axis is not aligned with the preset drilling point, the controller controls the rotating mechanism to drive the motor for fine-tuning, so that the drill rod rotates in the horizontal plane to the position aligned with the preset drilling point; at the same time, the longitudinal and transverse moving mechanisms are used again for fine-tuning so that the drill rod axis coincides with the center of the crosshair spot in the horizontal plane. S6: Auxiliary support; The controller outputs pulse signals to the drive motor of the support mechanism, causing the two symmetrically arranged top plates to move towards the side wall of the top beam with the drill rod axis as the center line of symmetry and automatically press against both sides of the position to be drilled. When the top plate contacts the side wall of the top beam and the pressure reaches the preset value, the controller cuts off the power to the drive motor of the support mechanism to form a stable auxiliary support. S7: Automatic drilling; The drilling motor is started to rotate forward and the number of rotations is counted in real time through the controller, and the drill rod is fed horizontally; When the drilling depth set in step S1 is reached, the controller automatically stops rotating forward and starts the drilling motor to rotate in reverse, driving the drill rod to exit the drilling surface; S8: Reset and operation of the next hole; The controller controls the support mechanism drive motor to reverse, so that the top plate is released; Then the controller controls the lifting motor to reverse, so that the working platform is lowered a certain distance; If the next hole is in the same horizontal plane but in a different orientation, the drill rod direction is finely adjusted directly through the rotating mechanism and steps S5 to S7 are repeated; If the position of the next hole changes significantly, the base is pushed to the next area and steps S2 to S7 are repeated.

[0016] The beneficial effects of this invention are as follows: 1. By setting up a base, lifting device and remote controller, the operator only needs to push the equipment and operate the controller on the ground, without having to climb to a high place to drill holes, thus completely avoiding the personal safety risk of falling from a height.

[0017] 2. The lifting device, longitudinal / lateral movement mechanism, rotation mechanism, and automatic drilling mechanism work together to achieve one-button lifting of the work platform, multi-dimensional automatic fine-tuning and alignment of the drill rod, and automatic feed and retraction. Especially when there are multiple drilling points in different orientations on the same horizontal plane, there is no need to lower the platform or move the base. Continuous operation can be achieved simply by adjusting the angle through the rotation mechanism. This overcomes the cumbersome "one-up-one-down" operation of traditional lifting frames, significantly improving the continuity and efficiency of operations.

[0018] 3. By projecting a crosshair laser module onto the target wall, aligning with the drill rod axis, and combining this with closed-loop feedback from the position detection device, a "what you see is what you get" non-contact precision positioning is achieved. The controller automatically controls the lifting height, drilling depth, and support clamping, reducing human measurement and operational errors and ensuring the consistency and accuracy of the drilling position.

[0019] 4. Symmetrical support mechanisms that can be synchronously driven by the controller are set on both sides of the drilling mechanism. Before drilling, the support mechanisms automatically tighten against the two side walls of the position to be drilled, providing stable auxiliary support for the entire system. This effectively counteracts the severe recoil and vibration generated during the drilling process, ensures the smoothness of the drill rod feed, prevents the drill rod from swaying, and thus improves the drilling quality and the service life of the equipment.

[0020] 5. The drilling mechanism adopts a combination connection structure of mounting block, fixing block, limit ring, locking block and U-shaped card block, which can quickly disassemble and assemble the drill rod without special tools, and facilitate the replacement of drill bit or maintenance according to different hole diameter requirements.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0023] A drilling system for medium and high-rise buildings, such as Figures 1 to 6 As shown, the device includes a base 1, with self-locking casters 19 at the bottom and a gantry bracket 3 at the top. A push handle 2 is connected to one side of the base 1 to facilitate the movement of the entire device by workers. To enhance structural stability, the push handle 2 and the gantry bracket 3 are fixedly connected by a reinforcing rod. The self-locking casters 19 allow the device to lock after being moved to a designated position, preventing accidental movement during operation.

[0024] A lifting device is provided in the middle of the upper surface of the base 1. The lifting device extends upward through the gantry bracket 3. A working platform 9 is connected to the top of the lifting device. A longitudinal moving mechanism 10, a transverse moving mechanism 11, a rotating mechanism, and a drilling mechanism 14 are connected in sequence above the working platform 9. Supporting mechanisms are provided on both sides of the drilling mechanism 14. The lifting mechanism includes a fixed sleeve 1424 mounted on the base 1. The top of the fixed sleeve 1424 extends above the gantry bracket 3, and a lifting rod 7 is movably mounted inside the fixed sleeve 1424. The working platform 9 is located on the top of the lifting rod 7. A tooth 21 is provided on one side of the lifting rod 7. A gear 6 that meshes with the tooth 21 is provided inside the fixed sleeve 1424. The gear 6 is fixed to the inner walls on both sides of the sleeve via a rotating shaft. A lifting motor 5 is provided on the outside of the sleeve, and the output shaft of the lifting motor 5 is coaxially connected to the rotating shaft.

[0025] When the lifting motor 5 starts, its output shaft drives the gear 6 to rotate. Through the meshing of the gear 6 and the teeth 21, the lifting rod 7 is driven to rise or fall smoothly within the fixed sleeve 1424, thereby driving the work platform 9 to rise or fall. This gear 6 rack and pinion lifting structure has the advantages of strong load-bearing capacity and smooth and controllable lifting.

[0026] Both the longitudinal moving mechanism 10 and the transverse moving mechanism 11 are lead screw and nut structures. Each mechanism includes a lead screw driven by a stepper motor and guide rods symmetrically arranged on both sides of the lead screw. The nut seat moves linearly along the guide rods under the drive of the lead screw. The longitudinal moving mechanism 10 is fixed on the work platform 9 and is used to drive the upper component to move in the front-back direction (Y-axis); the transverse moving mechanism 11 is mounted on the nut seat of the longitudinal moving mechanism 10 and is used to drive the upper component to move in the left-right direction (X-axis). This design enables precise positional fine-tuning of the drilling mechanism 14 in two horizontal dimensions.

[0027] In addition to using a lead screw and nut structure, the longitudinal moving mechanism 10 and the lateral moving mechanism 11 described above can also use a synchronous belt module or a gear and rack module, which can also achieve precise position control. As long as they can achieve precise linear displacement according to the controller's instructions, they should be considered equivalent replacements for the present invention.

[0028] The rotating structure includes a rotating shaft 141 mounted on a transverse moving mechanism 11, a driven bevel gear 6 connected to the rotating shaft 141, and a main bevel gear 6 meshing with the driven bevel gear 6. The main bevel gear 6 is driven by a rotary motor. A mounting base 13 is provided on the top of the rotating shaft 141, and a drilling mechanism 14 is provided on the mounting base 13.

[0029] When the rotary motor starts, it drives the rotating shaft 141 to rotate via a bevel gear pair. A mounting base 13 is provided on the top of the rotating shaft 141, and the drilling mechanism 14 is fixed on the mounting base 13. The rotating mechanism allows the drilling mechanism 14 to rotate ±90° or even 360° in the horizontal plane, thereby adjusting the direction of the drill rod 145 to align with drilling points in different directions.

[0030] The drilling mechanism 14 includes a drilling motor 140, a mounting block coaxially connected to the drilling motor 140, a fixing block 144 movably connected to the mounting block, and a drill rod 145 fixedly connected to the mounting block. An embedding groove is provided on one end of the mounting block near the fixing block 144. A limit ring 146 is fixedly fitted on the fixing block 144. Multiple locking blocks 147 are fixed on the outer circumferential surface of the mounting block. Bolts are provided on the locking blocks 147. A U-shaped locking block 143 corresponding to and cooperating with the locking block 147 is provided on the outer side of the limit ring 146. When the mounting block and the fixing block 144 are fixed, the locking block 143 is engaged with the locking block 147 and fixed by bolts.

[0031] When installing the drill rod 145, insert the drill rod 145 with the fixing block 144 into the groove of the mounting block until the limiting ring 146 abuts against the end face of the mounting block. Then rotate each U-shaped locking block 143 to engage with the corresponding locking block 147. Finally, tighten the bolts on the locking block 147 so that the ends of the bolts press against the U-shaped locking blocks 143, thereby firmly fixing the fixing block 144 to the mounting block. This connection method is convenient to install and disassemble, reliable, and allows for quick replacement of the drill rod 145 according to different hole diameters or wear conditions.

[0032] The support mechanism includes an L-shaped movable frame 17 and a top plate 18 located at the end of the movable frame 17. The movable frame 17 is driven by a screw and nut structure. The drive motor of this screw and nut structure is electrically connected to the controller. During the drilling preparation stage, the controller controls the drive motors on both sides to work synchronously, causing the two L-shaped movable frames 17 to drive the top plate 18, extending horizontally towards the side wall of the top beam 16 to be drilled, with the axis of the drill rod 145 as the center line of symmetry, until the top plate 18 is firmly pressed against the side walls of the drilling position. This mechanism provides a rigid auxiliary support for the drilling operation, effectively counteracting the huge reaction force generated during drilling and ensuring the stability of the system.

[0033] It also includes a laser positioning device and a controller. The laser positioning device includes at least one crosshair laser module 22, which is fixedly mounted on the fixing block 144 and has a horizontal laser emission direction. It is used to project a crosshair spot on the side wall of the top beam 16. The center of the crosshair spot coincides with the projection of the axis of the drill rod 145 onto the side wall plane of the top beam 16. Specifically, two or more crosshair laser modules 22 can be set and installed at different positions of the drilling mechanism 14. By using the crosshair positioning of multiple crosshair spots, the positioning accuracy and anti-interference ability are further improved.

[0034] The controller is electrically connected to the punching motor 140, the lifting motor 5, the drive motor of the longitudinal moving mechanism 10, the drive motor of the lateral moving mechanism 11, the drive motor of the support mechanism, and the rotary motor, respectively. The controller includes an input unit and a display unit for setting the drilling depth and lifting height; The controller is configured to: control the number of rotations of the drilling motor 140 according to the set drilling depth to achieve automatic feeding and retraction; control the start and stop of the lifting motor 5 according to the set lifting height to stop the work platform 9 at a preset position; receive operation commands and control the drive motors of the longitudinal moving mechanism 10, the transverse moving mechanism 11 and the rotating mechanism to achieve fine adjustment of the position of the drill rod 145; and control the drive motor of the support mechanism to achieve automatic tightening and loosening of the top plate 18.

[0035] In addition, the system includes a position detection device electrically connected to the controller. This device includes a first sensor for detecting the rising height of the lifting rod 7 and a second sensor for detecting the number of rotations of the drilling motor 140, thereby calculating the feed depth of the drill rod 145. These sensors are all electrically connected to the controller, forming a closed-loop control system. The first sensor can be a distance sensor or encoder mounted on the fixed sleeve 1424, and the second sensor can be a Hall sensor or encoder mounted on the shaft end of the drilling motor 140.

[0036] The drive motors of the longitudinal moving mechanism 10, the transverse moving mechanism 11, the rotating mechanism, and the supporting mechanism are all stepper motors with brakes. The controller controls the number of rotation steps of each stepper motor by outputting pulse signals. Example 2

[0037] A drilling method, implemented based on a drilling system for medium and high-rise buildings, includes the following steps: S1: Parameter setting; The operator first sets the drilling depth and the height that the lifting rod 7 needs to rise to in this drilling operation through the controller's input unit, such as a touch screen or buttons. S2: Equipment in place; The operator moves the entire equipment to the work area by pushing the base 1 with the hand-operated frame, and the initial direction of the drill rod 145 is horizontally pointed to the side wall of the top beam 16 to be drilled. S3: Automatic lifting; Start the lifting motor 5, and the lifting rod 7 will drive the working platform 9 and all the mechanisms above it to rise smoothly. The first sensor will feed back the height data to the controller in real time. When the lifting height value set in step S1 is reached, the controller will automatically cut off the power to the lifting motor 5 and stop lifting. At this time, the crosshair laser module 22 on the fixed block 144 has risen to the same height as the preset drilling point; S4: Laser coarse positioning; the laser positioning device is turned on, and the crosshair laser module 22 projects a clear crosshair spot on the side wall of the top beam 16. The worker holds the pusher 2 and finely adjusts the position of the base 1 so that the center of the projected crosshair spot is roughly aligned with the preset drilling point on the side wall; S5: Positioning and fine-tuning; If the axis of drill rod 145 is not aligned with the preset drilling point, the controller controls the rotating mechanism to drive the motor for fine-tuning, so that the drill rod 145 rotates in the horizontal plane to the position aligned with the preset drilling point; at the same time, the longitudinal moving mechanism 10 and the transverse moving mechanism 11 are fine-tuned again so that the axis of drill rod 145 coincides with the center of the cross spot in the horizontal plane. S6: Auxiliary support; The controller outputs pulse signals to the drive motor of the support mechanism, so that the axes of the two symmetrically arranged top plates 18 and the drill rod 145 are symmetrical center lines, and move towards the side wall of the top beam 16 respectively and automatically press against both sides of the position to be drilled. When the top plate 18 contacts the side wall of the top beam 16 and the pressure reaches the preset value, the controller cuts off the power supply to the drive motor of the support mechanism to form a stable auxiliary support. S7: Automatic drilling; The drilling motor 140 is started to rotate forward by the controller and the number of rotations is counted in real time, and the drill rod 145 is fed horizontally; When the drilling depth set in step S1 is reached, the controller automatically stops rotating forward and starts the drilling motor 140 to rotate in reverse, driving the drill rod 145 to exit the drilling surface. S8: Reset and operation of the next hole; the controller controls the support mechanism drive motor to reverse, so that the top plate 18 is released; then the controller controls the lifting motor 5 to reverse, so that the working platform 9 is lowered a certain distance; if the next hole is in the same horizontal plane but in a different orientation, the direction of the drill rod 145 is directly adjusted by the rotating mechanism and steps S5 to S7 are repeated; if the position of the next hole changes significantly, the base 1 is pushed to the next area and steps S2 to S7 are repeated.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
