Abstract
Description
Technical Field
[0001] This invention belongs to the field of pile-slab wall construction technology, specifically relating to an integrated machine for drilling holes for pile-slab wall anchor bolts. Background Technology
[0002] Pile-slab walls, as a common slope protection structure, are widely used in landslide control and slope reinforcement in highway, railway, and water conservancy projects. In pile-slab wall construction, anchor bolts are key components connecting the retaining slab and the anti-slide piles. The integrated pile-slab wall anchor bolt drilling machine is a specialized piece of machinery for this type of anchor bolt construction. This equipment can complete the positioning and drilling of anchor bolt holes on the outside of the anti-slide pile.
[0003] In the current design of integrated anchor bolt drilling machines, due to the large slenderness ratio and low radial bending stiffness of the anchor bolt itself, during drilling, the anchor bolt is only supported by the drive end and the front guide seat, while its middle section is in an unrestrained state. When the drill bit encounters uneven strata or obstacles, the non-uniform radial resistance applied to the drill bit will be converted into a lateral load that causes the anchor bolt to bend. This bending deformation will directly cause the drilling trajectory to deviate from the design axis, reducing the drilling accuracy. More seriously, when the drill bit contacts high-strength layers such as hard rock, the huge axial reaction force during continuous lateral movement will cause the anchor bolt to undergo compressive instability, resulting in significant back-pushing and bending deformation. This deformation not only aggravates the drilling deviation, but also directly transmits abnormal impact loads to the drive motor and propulsion hydraulic system, posing a risk of overload damage to the mechanical structure. At the same time, continuous rod vibration also accelerates the wear of the support components. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated drilling machine for pile-slab wall anchor bolts, in order to solve the problems mentioned in the background art, such as insufficient drilling accuracy and susceptibility to impact from hard layers in existing integrated drilling machines.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated machine for drilling anchor bolts in pile-slab walls, the integrated machine for drilling anchor bolts includes a support part, a drilling part, and a holding mechanism; The drilling section is located above the support section, and the support section is equipped with a drive component that drives the drilling section to slide horizontally. The holding mechanism consists of a frame structure, a holding component, and a detection component; in: The frame structure is located inside the support and is fitted onto the outside of the drilled part; the frame structure moves in the same direction when the drilled part slides horizontally. The retaining component is placed inside the frame structure and rotates synchronously with the drilling section; The detection component is disposed between the retaining component and the frame structure. The detection component is wired or wirelessly connected to the driving component, and the detection component closes the extension of the driving component when the retaining component is reversed and pressed.
[0006] As a preferred technical solution of the present invention, the frame structure includes a retainer with a central hole on its surface, and the retaining component and the detection component are both placed in the central hole; wherein the bottom end of the retainer extends downward to form two support points. Compared with a single square structure, this structural design can also reduce the weight of the entire retainer. The support includes a base, and a slide rail is fixed on the inner bottom surface of the base for the bottom end of the retainer to slide, thereby realizing the sliding of the retainer inside the base.
[0007] As a preferred technical solution of the present invention, the retaining assembly includes an inner cylinder, a bearing, and a threaded ring; The inner cylinder is composed of two semi-cylinders, forming a cylindrical structure. Both ends of the semi-cylinders are threaded, allowing for adjustments based on the anchor rod's dimensions. The drilling section includes a servo motor and an anchor rod mounted on the servo motor's output. The anchor rod has spiral protrusions on its outer surface. The inner walls of the semi-cylinders are provided with spiral grooves that fit the outer walls of the anchor rod. Therefore, when the anchor rod is rotated by the servo motor, it drives the inner cylinder to rotate synchronously. One end of the inner cylinder protrudes outside the retainer, while the other end is placed inside the central hole. The bearing is sleeved on the outside of the inner cylinder, and the outer wall of the bearing abuts against the inner wall of the central hole. When the inner cylinder rotates, it will not drive the outer wall of the bearing and the retainer to rotate, thereby avoiding motion interference and reducing the friction force on the inner wall of the central hole when the inner cylinder rotates, thus reducing wear. At least two threaded rings are provided and symmetrically fitted at the threads at both ends of half-cylinder one and half-cylinder two. The threaded rings can limit the connection of half-cylinder one and half-cylinder two to form a complete inner cylinder. At the same time, the inner cylinder will not be loose. The side of the bearing abuts against the inner side of the threaded ring. The threaded rings limit the bearing and ensure that the position of the inner cylinder and the bearing will not change.
[0008] As a preferred technical solution of the present invention, the detection component includes a built-in spring, a mounting ring, and a pressure sensor; The built-in spring is sleeved on the other end of the inner cylinder, and one end of the built-in spring abuts against the threaded ring on the other end of the inner cylinder; The mounting ring is installed on one side of the retainer and blocks the central hole portion, while the pressure sensor is installed inside the mounting ring and inside the central hole, and the pressure sensor abuts against the other end of the built-in spring; The mounting ring and pressure sensor are concentrically distributed, and a hole for the anchor rod to pass through is opened at the center of both.
[0009] As a preferred technical solution of the present invention, a limiting end ring is also installed on the other side of the retainer. The limiting end ring is sleeved on one end of the inner cylinder and abuts against the threaded ring at one end of the inner cylinder. By setting the limiting end ring, the inner cylinder can be limited to the middle hole and will not move axially towards the outside of the retainer. With the bearing, radial position jump of the inner cylinder can be avoided. When the end of the anchor rod encounters the hard layer and generates a reaction force, it will simultaneously drive the inner cylinder to move towards the mounting ring. At this time, the inner cylinder will squeeze the built-in spring. At this time, the pressure monitored by the pressure sensor changes and exceeds the threshold. At this time, the pressure sensor will stop the drive to avoid the entire drilling part from continuing to squeeze, which would cause a large reaction force and severe deformation of the anchor rod. At this time, the anchor rod is in the current position for drilling. At the same time, under the rebound of the built-in spring, it always adheres to the hard layer. When the drilling of the hard layer is completed, the built-in spring resets. At this time, the pressure of the pressure sensor returns to the normal value, and the drive continues to run.
[0010] As a preferred technical solution of the present invention, a guide seat is also provided at one end of the top of the base. The guide seat has a hole for the anchor rod to pass through. The guide seat and the retaining mechanism are used to support the end and middle of the anchor rod.
[0011] As a preferred technical solution of the present invention, the bottom end of the servo motor is also equipped with a sliding seat that is slidably disposed on the top of the base. The end of the sliding seat facing the direction of the retainer extends vertically downward and forms a protrusion. It also includes a pushing component, which includes a snap-fit part and a pushing part; The snap-fit part is located inside the sliding seat, while the push part is fixed to the retainer; One end of the pushing part is limited and stopped by the locking part.
[0012] As a preferred technical solution of the present invention, the pushing part is a push rod that passes through the protrusion of the sliding seat. The top of the push rod is provided with a sliding groove, and a limiting plate is fixed inside the sliding groove. The limiting plate and the end of the sliding groove form a pushing groove. The bottom end of the snap-fit part is inserted into the pushing groove, and the height of the limiting plate is lower than the depth of the sliding groove.
[0013] As a preferred technical solution of the present invention, a vertical hole is opened in the protrusion of the sliding seat, and the locking part includes a push post disposed in the vertical hole. An adjusting spring is connected above the push post. The bottom two sides of the push post are inclined, and the height of the inclined area of the push post exceeds the limit plate but is lower than the depth of the slide groove. When the sliding seat is driven by the driving component, the push post will push the limit plate, and the limit plate will drive the push rod, thereby driving the entire holding mechanism to move synchronously with the servo motor. When the anchor rod continues to drill in and the holding mechanism is in contact with the guide seat, the position of the holding mechanism will be limited. At this time, the inclined part of the push post will pass the limit plate and move in the slide groove. At this time, the sliding seat no longer drives the push rod to move, thereby achieving the purpose of continuing to drill the anchor rod. When exiting the anchor rod, the push post will pass the limit plate and be limited by the inner wall of the end of the slide groove, thereby pulling the push rod.
[0014] In a preferred embodiment of the present invention, the driving component is a hydraulic rod, the extended end of which is connected to the bottom end of the sliding seat; the hydraulic rod has a control module that is wirelessly or wiredly connected to the pressure sensor.
[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a retaining mechanism with sensing function is added. This retaining mechanism provides intermediate radial constraint for the anchor rod throughout the entire process, suppressing bending vibrations during conventional drilling and fundamentally ensuring the straightness accuracy of the hole. At the same time, the detection component integrated in the retaining mechanism can sense abnormal axial thrust encountered by the anchor rod in real time. When it is determined that the drill bit is in contact with hard rock, the hydraulic propulsion can be automatically paused and the mode can be switched to constant pressure drilling. At this time, the spring in the retaining mechanism is compressed and stored energy, which can ensure that the drill bit always breaks the rock with constant pressure, avoiding impact overload, and also prevent the drill bit from slipping due to detachment from the rock surface. After the hard rock is broken and the resistance drops back to the normal range, the propulsion is automatically resumed. This improvement enables the equipment to adapt to changes in strata, achieving a smooth, accurate and efficient construction process, while significantly reducing the probability of mechanical impact damage.

Detailed Implementation
[0018] 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.
[0019] Please see Figures 1 to 8 The present invention provides a technical solution: an integrated machine for drilling holes for pile-slab wall anchor bolts, which includes a support part, a drilling part, and a holding mechanism; The drilling section is located above the support section, and the support section is equipped with a drive component that drives the drilling section to slide horizontally. The retaining mechanism consists of a frame structure, retaining components, and detection components; in: The frame structure is located inside the support and is fitted onto the outside of the drilled part; the frame structure moves in the same direction when the drilled part slides horizontally. Keep the component inside the frame structure and rotate synchronously with the drilled part; The detection component is positioned between the retaining component and the frame structure. The detection component is wired or wirelessly connected to the drive component, and the detection component closes the extension of the drive component when the retaining component is reversed and pressed.
[0020] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The frame structure includes a retainer 301, on the surface of which a central hole 301a is provided. Both the retaining component and the detection component are placed inside the central hole 301a. The bottom end of the retainer 301 extends downward to form two support points. Compared with a single square structure, this structural design can reduce the weight of the entire retainer 301. The support includes a base 100, and a slide rail 102 is fixed on the bottom surface inside the base 100 for the bottom end of the retainer 301 to slide, thereby realizing the sliding of the retainer 301 inside the base 100.
[0021] In this embodiment, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 The retaining components include an inner cylinder 302, a bearing 304, and a threaded ring 308; The inner cylinder 302 is a cylindrical structure composed of half-cylinder 302a and half-cylinder 302b, and both ends of half-cylinder 302a and half-cylinder 302b are threaded. This structure allows for adjustment and replacement according to the size of the anchor rod 202. The drilling part includes a servo motor 200 and the anchor rod 202 installed on the output part of the servo motor 200. The outer surface of the anchor rod 202 has spiral protrusions. The inner walls of half-cylinder 302a and half-cylinder 302b are provided with spiral grooves that fit the outer wall of the anchor rod 202. Therefore, when the anchor rod 202 is rotated by the servo motor 200, it will drive the inner cylinder 302 to rotate synchronously. One end of the inner cylinder 302 protrudes to the outside of the retainer 301, and the other end is placed inside the central hole 301a. The bearing 304 is sleeved on the outside of the inner cylinder 302, and the outer wall of the bearing 304 abuts against the inner wall of the central hole 301a. When the inner cylinder 302 rotates, it will not drive the outer wall of the bearing 304 and the retainer 301 to rotate, thereby avoiding motion interference and reducing the friction force on the inner wall of the central hole 301a when the inner cylinder 302 rotates, thus reducing wear. At least two threaded rings 308 are provided and symmetrically sleeved on the threads at both ends of the first half-cylinder 302a and the second half-cylinder 302b. The threaded rings 308 can limit the connection of the first half-cylinder 302a and the second half-cylinder 302b to form the complete inner cylinder 302. At the same time, the inner cylinder 302 will not be loose. The side of the bearing 304 abuts against the inner side of the threaded rings 308. The threaded rings 308 limit the bearing 304 and ensure that the positions of the inner cylinder 302 and the bearing 304 do not change.
[0022] In this embodiment, refer to Figure 4 , Figure 5 , Figure 6 The detection components include a built-in spring 305, a mounting ring 306, and a pressure sensor 307; The built-in spring 305 is sleeved on the other end of the inner cylinder 302, and one end of the built-in spring 305 abuts against the threaded ring 308 on the other end of the inner cylinder 302; Mounting ring 306 is mounted on one side of retainer 301 and partially blocks the central hole 301a, while pressure sensor 307 is mounted inside mounting ring 306 and inside central hole 301a. Pressure sensor 307 abuts against the other end of built-in spring 305. The mounting ring 306 and the pressure sensor 307 are concentrically distributed, and a hole for the anchor rod 202 to pass through is opened at the center of both.
[0023] In this embodiment, refer to Figure 4 On the other side of the retainer 301, a limiting end ring 303 is also installed. This limiting end ring 303 is sleeved on one end of the inner cylinder 302 and abuts against the threaded ring 308 at one end of the inner cylinder 302. By setting the limiting end ring 303, the inner cylinder 302 can be completely limited within the central hole 301a, preventing axial movement towards the outside of the retainer 301. In conjunction with the bearing 304, radial movement of the inner cylinder 302 can be avoided. When the end of the anchor rod 202 encounters the hard layer and generates a reaction force, it will simultaneously drive the inner cylinder 302 towards the mounting ring 306. When the device moves in the direction of the hole, the inner cylinder 302 will compress the built-in spring 305. At this time, the pressure monitored by the pressure sensor 307 changes and exceeds the threshold. The pressure sensor 307 then stops the drive to prevent the entire drilling section from continuing to be compressed, which would cause a large reaction force and severe deformation of the anchor rod 202. At this time, the anchor rod 202 is in the current position for drilling. At the same time, under the rebound of the built-in spring 305, it always adheres to the hard layer. When the drilling of the hard layer is completed, the built-in spring 305 resets, and the pressure of the pressure sensor 307 returns to the normal value. The drive then continues to operate.
[0024] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 A guide seat 203 is also provided at one end of the top of the base 100. The guide seat 203 has a hole through which the anchor rod 202 passes. The guide seat 203 and the retaining mechanism 300 provide support for the end and middle of the anchor rod 202.
[0025] In this embodiment, refer to Figure 2 , Figure 3 , Figure 7 , Figure 8 The bottom end of the servo motor 200 is also equipped with a sliding seat 201 that is slidably disposed on the top of the base 100. The end of the sliding seat 201 facing the holder 301 extends vertically downward and forms a protrusion. It also includes a push component 400, which includes a snap-fit portion and a push portion; The snap-fit part is located inside the slide seat 201, while the push part is fixed on the retainer 301; One end of the propulsion unit is stopped by the locking part.
[0026] In this embodiment, refer to Figure 8 The pushing part is a push rod 401, which passes through the protrusion of the sliding seat 201. The top of the push rod 401 is provided with a sliding groove 401a. A limiting plate 401b is fixed inside the sliding groove 401a. The limiting plate 401b and the end of the sliding groove 401a form a pushing groove 401c. The bottom end of the snap-fit part is inserted into the pushing groove 401c. The height of the limiting plate 401b is lower than the depth of the sliding groove 401a.
[0027] In this embodiment, refer to Figure 8 A vertical hole is formed in the protrusion of the sliding seat 201. The engaging part includes a push post 402 disposed in the vertical hole. An adjusting spring 403 is connected above the push post 402. The bottom sides of the push post 402 are inclined, and the height of the inclined area of the push post 402 exceeds the limit plate 401b but is lower than the depth of the slide groove 401a. When the sliding seat 201 is driven by the driving component, the push post 402 pushes the limit plate 401b, which in turn drives the push rod 401, thereby driving the entire holding mechanism 300 to follow the servo motor 2. 00 Synchronous movement: When the anchor rod 202 continues to drill and the holding mechanism 300 is in contact with the guide seat 203, the position of the holding mechanism 300 will be limited. At this time, the inclined part of the push rod 402 will pass the limiting plate 401b and move in the slide groove 401a. At this time, the sliding seat 201 will no longer drive the push rod 401 to move, thereby achieving the purpose of continuing to drill the anchor rod 202. When exiting the anchor rod 202, the push rod 402 will pass the limiting plate 401b and be limited by the inner wall of the end of the slide groove 401a, thereby pulling the push rod 401.
[0028] In this embodiment, refer to Figure 1 The driving component is a hydraulic rod 101, the extended end of which is connected to the bottom end of the sliding seat 201; the hydraulic rod 101 has a control module that is wirelessly or wiredly connected to the pressure sensor 307.
[0029] The working principle of the integrated pile-slab wall anchor bolt drilling machine is explained below: During drilling, the anchor rod 202 is installed first, and then the hydraulic rod 101 is activated, pushing the sliding seat 201 to slide along the top of the base 100, thereby driving the servo motor 200 and the anchor rod 202 to extend horizontally together; when the sliding seat 201 moves, the push column 402 in its protrusion pushes the push rod 401 through the limiting plate 401b, so that the holding mechanism 300 moves forward synchronously with the servo motor 200; the inner cylinder 302 engages with the protrusion on the outer wall of the anchor rod 202 through the spiral groove on the inner wall, and drives the inner cylinder 302 to rotate synchronously when the servo motor 200 rotates; When the front end of the anchor rod 202 encounters a hard layer during drilling, the reverse resistance pushes the anchor rod 202 and the inner cylinder 302 to move slightly towards the mounting ring 306. At this time, the threaded ring 308 compresses the built-in spring 305 and increases the pressure on the pressure sensor 307. When the pressure sensor 307 detects that the pressure exceeds the set threshold, it automatically controls the hydraulic rod 101 to stop extending. At this time, the anchor rod 202 continues to rotate and drill in the current position, and the built-in spring 305 remains compressed, so that the drill bit always presses against the hard layer to achieve constant pressure rock breaking. After the hard layer is penetrated and the resistance decreases, the built-in spring 305 rebounds, the pressure of the pressure sensor 307 returns to the normal range, and the hydraulic rod 101 restarts and continues to advance. If the holding mechanism 300 cannot move forward during drilling due to contact with the guide seat 203, the inclined part of the push rod 402 will slide along the limiting plate 401b and enter the slide groove 401a. At this time, the sliding seat 201 continues to move forward while the holding mechanism 300 remains stationary, realizing the independent drilling of the anchor rod 202. When retracting the drill, the hydraulic rod 101 retracts in the opposite direction, and the sliding seat 201 moves backward. At this time, the push rod 402 is limited by the inner wall of the end of the slide groove 401a, pulling the push rod 401 and the holding mechanism 300 backward in sync until they are completely retracted.
[0030] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
