Description

An anchor drilling device for slope protection Technical Field

[0001] This invention relates to the field of drilling equipment technology, and more specifically, to an anchor drilling device for slope support. Background Technology

[0002] Slope support anchors are engineering structures that enhance slope stability through anchoring. They are made of materials such as metal and polymer, driven into pre-drilled anchor holes in the slope, and then grouted with concrete to enhance slope stability and ensure the safety of subsequent slope construction.

[0003] Current anchor bolt drilling equipment often results in soil from the borehole wall falling into the hole after drilling. Therefore, after each drilling operation, a cleaning device must be inserted into the borehole to clean the wall. This process is inefficient because it requires removing the drill bit and then inserting and removing the cleaning device. Furthermore, even after cleaning, the soil remaining on the borehole wall is still loose, affecting the quality of subsequent grouting. Summary of the Invention

[0004] The purpose of this invention is to provide an anchor drilling device for slope support, which can improve the efficiency of the entire drilling process and level the hole wall of the anchor bolt, thereby improving the quality of subsequent grouting.

[0005] The present invention is achieved through the following technical solution: a drilling device for anchor bolts for slope support, comprising a mobile body, a mechanical arm mounted on the mobile body, a drilling platform mounted on the end of the mechanical arm away from the mobile body, a drilling mechanism and a drive mechanism for driving the drilling mechanism to move along the length direction of the drilling platform, the drilling mechanism comprising a drill bit, multiple drill rods, and an external rotating component for driving the multiple drill rods to rotate synchronously;

[0006] The external rotating assembly is slidably mounted on the drilling platform. The multiple drill rods are detachably connected end to end in sequence. The drill rod located at the tail end of the drilling mechanism is detachably connected to the external rotating assembly, and the drill bit is detachably connected to the drill rod located at the head end of the drilling mechanism.

[0007] The drill rod is a hollow rod, and each drill rod is provided with a leveling component to level and stabilize the wall of the anchor bolt hole. The outer rotating component is provided with an inner rotating component for driving the leveling component to rotate as a whole.

[0008] The leveling assembly includes a support rod, a spiral plate, and an elastic leveling plate. The support rod is rotatably disposed inside the drill rod, and a connector is provided between the support rods of two adjacent drill rods. The inner edge of the spiral plate is fixedly disposed on the support rod, and the elastic leveling plate is fixedly connected to the outer edge of the spiral plate. A notch is provided on the side wall of the drill rod for the elastic leveling plate to move out.

[0009] Furthermore, the end of the elastic leveling plate away from the vortex-shaped plate is provided with an arc-shaped fold. After the elastic leveling plate moves out of the notch, when the outer rotating component drives the leveling component to rotate, the arc-shaped fold can abut against the hole wall of the anchor bolt hole and guide excess soil into the drill rod through the notch.

[0010] Furthermore, the connector includes a connector block and a connector seat. The connector seat has a connector groove for inserting the connector block and restricting the rotation of the connector block. An anti-rotation member is provided on the side wall of the connector seat. An anti-rotation groove is provided on the side wall of the drill rod for inserting the anti-rotation member. When the connector block is inserted into the connector groove, it can drive the anti-rotation member to disengage from the anti-rotation groove.

[0011] Furthermore, a strip groove communicating with the insertion slot is provided on the side wall of the insertion socket, and the anti-rotation member includes an anti-rotation block hinged in the strip groove. An elastic abutment piece for driving the anti-rotation block into the anti-rotation slot is connected between the anti-rotation block and the end wall of the strip groove.

[0012] Furthermore, the external rotation assembly includes a base, on which an external rotation motor is mounted. A drive disk is mounted on the output shaft of the external rotation motor, and a connecting shaft is mounted on the drive disk for connecting to a drill rod located at the tail end of the drilling mechanism. The connecting shaft is detachably connected to the drill rod located at the tail end of the drilling mechanism, to two adjacent drill rods, and to the drill rod and drill bit located at the head end of the drilling mechanism via the connecting assembly.

[0013] Furthermore, the connecting assembly includes a connecting sleeve, on which a connecting bolt is disposed, and threaded holes for inserting the connecting bolt are provided on the connecting shaft, drill rod, and drill bit.

[0014] Furthermore, the inner rotating assembly includes a rotating disk, which is rotatably disposed within a drive disk. A connector strip is provided in the middle of the rotating disk. After the drill rod located at the tail end of the drilling mechanism is connected to the connecting shaft through a connecting assembly, the connector strip is inserted into the connector slot. A gear ring assembly for driving the rotating disk to rotate is provided on the drive disk.

[0015] Furthermore, the gear ring assembly includes an inner rotating motor, which is fixedly mounted on the drive disk. A drive gear is mounted on the output shaft of the inner rotating motor, and a driven gear ring that meshes with the drive gear is mounted on the outer circumferential surface of the rotating disk.

[0016] Furthermore, the driving mechanism includes a drive motor, a lead screw, and a drive block. Mounting seats are provided at both ends of the bottom of the drilling platform. The lead screw is rotatably connected between the two mounting seats. The drive motor is fixedly mounted on one of the mounting seats, and the output shaft of the drive motor is fixedly connected to the lead screw. The drive block is threadedly connected to the lead screw. A sliding groove is provided on the drilling platform for the drive block to slide. The top end of the drive block passes through the sliding groove and is fixedly connected to the base.

[0017] Furthermore, rollers are provided on both sides of the base, and the drilling platform is provided with a chute for the rollers to roll.

[0018] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0019] 1. This invention sets a leveling component on each drill rod. After the drilling process is completed, the inner rotating component drives the support rod to rotate, thereby causing the vortex-shaped plate to rotate synchronously. This causes the elastic leveling plate to move out of the notch and fit against the side wall of the anchor hole. Then, the outer rotating component drives the entire drill rod to rotate. The elastic leveling plate can level the side wall of the anchor hole and collect the excess soil scraped off during the leveling process into the vortex-shaped plate.

[0020] 2. The present invention provides a plug-in block at one end and a plug-in seat at the other end of a support rod inside each drill rod, and an anti-rotation component at the plug-in seat to fix the position of the plug-in seat and the drill rod, so as to ensure the consistency of the position of the leveling component inside the drill rod. After installation, multiple support rods can rotate synchronously under the drive of the internal rotating component so that the leveling component can move out of the notch to level the hole wall of the anchor bolt hole.

The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] Example

[0033] Referring to Figures 1-8, and in conjunction with specific embodiments, this embodiment provides an anchor drilling device for slope support. Referring to Figures 1 and 2, it includes a mobile body 1, a robotic arm 2 mounted on the mobile body 1, and a drilling platform 3 mounted at the end of the robotic arm 2 away from the mobile body 1. The drilling platform 3 is equipped with a drilling mechanism 4 and a drive mechanism 5 for driving the drilling mechanism 4 to move along the length of the drilling platform 3. The drilling mechanism 4 includes a drill bit 41, multiple drill rods 42, and an external rotating assembly 43 for driving the multiple drill rods 42 to rotate synchronously. The external rotating assembly 43 is slidably mounted on the drilling platform 3. The multiple drill rods 42 are detachably connected end-to-end and located at the drilling mechanism. The drill rod 42 at the tail end of the drilling mechanism 4 is detachably connected to the external rotating assembly 43, and the drill bit 41 is detachably connected to the drill rod 42 at the head end of the drilling mechanism 4. When drilling, the drill bit 41 is installed on the drill rod 42 at the head end of the drilling mechanism 4, and then the drill rod 42 at the tail end of the drilling mechanism 4 is installed on the external rotating assembly 43. The external transmission assembly is activated to drive the drill rod 42 and the drill bit 41 to rotate as a whole, and the drive mechanism 5 is activated to drive the drilling mechanism 4 to advance as a whole to drill on the slope. After drilling a certain distance, the drill rod 42 at the tail end of the drilling mechanism 4 is detached from the external transmission assembly, and a new drill rod 42 is added to extend the overall length of the drilling mechanism 4, thereby increasing the drilling depth.

[0034] Referring to Figure 2, the drive mechanism 5 includes a drive motor 51, a lead screw 52, ​​and a drive block 53. Mounting seats 54 are provided at both ends of the bottom of the drilling platform 3. The lead screw 52 is rotatably connected between the two mounting seats 54. The drive motor 51 is fixedly mounted on one of the mounting seats 54, and its output shaft is fixedly connected to the lead screw 52. The drive block 53 is threadedly connected to the lead screw 52. A sliding groove is provided on the drilling platform 3 for the drive block 53 to slide. The top end of the drive block 53 passes through the sliding groove and is fixedly connected to the base 431. Starting the drive motor 51 rotates the lead screw 52, ​​allowing the drive block 53 to slide along the length of the drilling platform 3, thereby conveying the drilling mechanism 4 forward for drilling operations on the slope surface. Referring to Figure 3, to improve the smoothness of the base 431's movement, rollers 4311 are provided on both sides of the base 431. A rolling groove is provided on the drilling platform 3 for the rollers 4311 to roll.

[0035] Referring to Figures 3 and 4, the drill rod 42 is a hollow rod. Each drill rod 42 is equipped with a leveling component 44 to level and stabilize the wall of the anchor bolt hole. The outer rotating component 43 is equipped with an inner rotating component 45 for driving the leveling component 44 to rotate as a whole. Referring to Figure 5, the leveling component 44 includes a support rod 441, a spiral plate 442, and an elastic leveling plate 443. The support rod 441 is rotatably disposed inside the drill rod 42. A connector 46 is provided between the support rods 441 in two adjacent drill rods 42. The inner edge of the spiral plate 442 is fixedly disposed on the support rod 441. The elastic leveling plate 443 is fixedly connected to the outer edge of the spiral plate 442. A notch 421 is provided on the side wall of the drill rod 42 for the elastic leveling plate 443 to move out. After the drilling process is completed, the inner rotating component 45 drives the support rod 441 to rotate, which in turn drives the vortex plate 442 to rotate synchronously. During the rotation of the vortex plate 442, the elastic leveling plate 443 moves out of the notch 421 and fits against the side wall of the anchor hole. Then, the outer rotating component 43 drives the drill rod 42 to rotate as a whole. The elastic leveling plate 443 can level the side wall of the anchor hole and guide the excess soil scraped off during the leveling process into the vortex plate 442. The vortex plate 442 can continuously transport the soil from the outer edge to the inner edge, thereby collecting the soil. After leveling a certain distance, the drive mechanism 5 is activated to drive the drilling mechanism 4 to move a certain distance out of the anchor hole to level the anchor hole at the next position. Finally, the entire anchor hole wall is flat, which improves the subsequent grouting quality.

[0036] Referring to Figures 5 and 6, the end of the elastic leveling plate 443 away from the vortex-shaped plate 442 is provided with an arc-shaped folded portion 4431. After the elastic leveling plate 443 moves out of the notch 421, when the outer rotating component 43 drives the leveling component 44 to rotate, the arc-shaped folded portion 4431 can abut against the hole wall of the anchor bolt hole and guide excess soil into the drill rod 42 through the notch 421, so as to facilitate the collection of excess soil and avoid local accumulation of soil in the anchor bolt hole, which would affect the subsequent grouting process. Moreover, the arc-shaped folded portion 4431 can increase the contact area with the soil and improve the leveling effect of the anchor bolt hole.

[0037] Referring to Figures 3 and 4, the outer rotating assembly 43 includes a base 431, on which an outer rotating motor 432 is mounted. A drive disk 433 is mounted on the output shaft of the outer rotating motor 432. A connecting shaft 434 is mounted on the drive disk 433 for connecting to the drill rod 42 located at the tail end of the drilling mechanism 4. The connecting shaft 434 is detachably connected to the drill rod 42 at the tail end of the drilling mechanism 4, to adjacent drill rods 42, and to the drill rod 42 and drill bit 41 at the head end of the drilling mechanism 4 via a connecting assembly 47. The connecting assembly 47 includes a connecting sleeve 471, on which a connecting bolt 472 is mounted. Threaded holes for the connecting bolt 472 are provided on the connecting shaft 434, the drill rod 42, and the drill bit 41. The connecting sleeve 471 and connecting bolt 472 can be used to easily and stably connect components such as drill rod 42, connecting shaft 434 and drill bit 41, so that the drilling mechanism 4 can be extended to a specified length during the drilling operation, and the components can be easily disassembled after the drilling process is completed.

[0038] Referring to Figures 5 and 6, the connector 46 includes a connector block 461 and a connector seat 462. Each drill rod 42 has a connector block 461 at one end of its support rod 441 near the drill bit 41 and a connector seat 462 at the other end away from the drill bit 41. The connector seat 462 has a connector groove for inserting the connector block 461 and restricting its rotation. An anti-rotation member 463 is provided on the side wall of the connector seat 462, and an anti-rotation groove is provided on the side wall of the drill rod 42 for inserting the anti-rotation member 463. When the connector block 461 is inserted into the connector groove, it can drive the anti-rotation member 463 to disengage from the anti-rotation groove. When the drill rod 42 is not installed, the relative position of the support rod 441 and the drill rod 42 is fixed under the action of the anti-rotation member 463, and relative rotation will not occur. During the drilling operation, drill rods 42 need to be continuously added to increase the drilling depth. Each time a drill rod 42 is added, after the added drill rod 42 is connected to the drill rod 42 in the direction close to the drill bit 41, the plug block 461 on the support rod 441 of the next drill rod 42 is inserted into the plug seat 462 on the support rod 441 of the previous drill rod 42, releasing the position restriction between the previous support rod 441 and the drill rod 42. However, the relative position between the next support rod 441 and the drill rod 42 is still restricted. When all drill rods 42 are installed, the inner rotating component 45 can release the restriction on the position between the drill rod 42 and the support rod 441 located at the tail end of the drilling mechanism 4, and can drive multiple support rods 441 to rotate synchronously, thereby driving the leveling component 44 to rotate as a whole.

[0039] Referring to Figures 6 and 7, a strip groove communicating with the insertion slot is provided on the side wall of the insertion base 462. The anti-rotation member 463 includes an anti-rotation block 4631 hinged in the strip groove. An elastic abutment piece 4632 for driving the anti-rotation block 4631 into the anti-rotation slot is connected between the anti-rotation block 4631 and the end wall of the strip groove. When no external force is applied, the anti-rotation block 4631 is located in the anti-rotation slot under the action of the elastic abutment piece 4632. At this time, there is no relative rotation between the support rod 441 and the drill rod 42. When the insertion block 461 is inserted into the insertion slot of the insertion base 462, the end of the insertion block 461 abuts against the part of the anti-rotation block 4631 located in the insertion slot, causing the anti-rotation block 4631 to flip and disengage from the anti-rotation slot, releasing the restriction on the position between the support rod 441 and the drill rod 42. At this time, the support rod 441 and the drill rod 42 can rotate relative to each other. It should be noted that the plug block 461 has an inclined surface at one end located in the plug slot. When the plug block 461 is fully inserted into the plug slot, the inclined surface is in contact with the anti-rotation block 4631.

[0040] Referring to Figures 3 and 8, the inner rotating assembly 45 includes a rotating disk 451, which is rotatably mounted inside the drive disk 433. A connector strip 452 is provided in the middle of the rotating disk 451. After the drill rod 42 located at the tail end of the drilling mechanism 4 is connected to the connecting shaft 434 via a connecting assembly 47, the connector strip 452 is inserted into the connector slot. The drive disk 433 is provided with a gear ring assembly 453 for driving the rotating disk 451 to rotate. Specifically, the gear ring assembly 453 includes an inner rotating motor 4531, which is fixedly mounted on the drive disk 433. A drive gear 4532 is provided on the output shaft of the inner rotating motor 4531, and a driven gear ring 4533 meshing with the drive gear 4532 is provided on the outer circumferential surface of the rotating disk 451. When the internal rotating motor 4531 is started, the output shaft of the rotating motor drives the drive gear 4532 to rotate. The driven gear ring 4533, which meshes with the drive gear 4532, rotates and drives the rotating disk 451 to rotate. This, in turn, drives the support rod 441 to rotate through the plug bar 452, so that the leveling assembly 44 rotates as a whole.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
