Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and more specifically to an actuator based on a drilling rig. Background Technology

[0002] Drilling rigs, as key equipment widely used in geological exploration, mining, construction, and tunnel engineering, primarily perform drilling operations through methods such as rotary cutting or impact crushing. However, with increasingly complex construction processes and ever-growing demands for efficiency, safety, and automation, traditional single-function drilling rigs are no longer sufficient to meet the needs of modern engineering projects.

[0003] Currently, after drilling is completed, a series of follow-up procedures are often required, such as the installation of anchor bolts (cables), grouting, hole enlargement, pile formation, or cleaning around the borehole and assisting in pipe laying. A few improved drilling rigs have attempted to integrate some of these follow-up procedures onto the drilling rig by adding simple auxiliary function modules to the power head or other parts of the rig body.

[0004] The new actuators added to traditional improved drilling rigs are often bulky and seriously interfere with the original drilling and feeding systems in space. This not only limits the drilling capacity of the rig itself (such as drilling depth and angle), but may also restrict the movement of the new mechanism and result in poor functional performance. Summary of the Invention

The output end of the first rotary drive unit is fixedly connected to a convex housing. A second rotary drive unit is mounted on the side of the convex housing away from the first rotary drive unit. A hexagonal cylinder is fixedly connected to the output end of the second rotary drive unit. A high-pressure rotary jet grouting drill bit is mounted on the outside of the hexagonal cylinder. A third rotary drive unit is mounted on the side of the hexagonal cylinder away from the second rotary drive unit. A hydraulic impact drilling drill bit is mounted on the output end of the third rotary drive unit.

[0010] Preferably, a protective shell is fixedly connected to the outer side of the base, and a worm is rotatably connected to the inner wall of the protective shell through a bearing, with the outer side of the worm meshing with the outer side of the worm wheel.

[0011] Preferably, a hydraulic motor is installed on the outside of the protective housing, the end of the worm gear near the hydraulic motor passes through the protective housing and extends to the outside of the protective housing, and the output shaft of the hydraulic motor is fixedly connected to the end of the worm gear located outside the protective housing by a coupling.

[0012] Preferably, the protective shell has a first connecting groove on the side near the base, and the base has a second connecting groove on the side near the protective shell.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments. Example 1:

[0023] Reference Figure 1-6 The first embodiment of the present invention discloses an actuator based on a drilling rig, comprising: Drive unit 1, driven by tracks, and equipped with the control unit of the drilling rig; The operation execution component 3 includes a first rotary drive 32 mounted on the outside of the adjusting seat 21. A convex housing 31 is fixedly connected to the output end of the first rotary drive 32. The first rotary drive 32 is used for coarse adjustment of the overall position of the two drill bits. By driving the convex housing 31 to rotate, the entire drilling system can be quickly adjusted to the vicinity of the working area, achieving a wide range of position adjustments and laying the foundation for subsequent precise adjustments. A second rotary drive 35 is mounted on the side of the convex housing 31 away from the first rotary drive 32. A hexagonal cylinder 33 is fixedly connected to the output end of the second rotary drive 35. The second rotary drive 35 is used for individual fine adjustment of the two drill bits. By controlling the rotation angle of the hexagonal cylinder 33, the position of each drill bit can be adjusted independently and precisely to meet the personalized requirements of different drilling operations for drill bit position. A high-pressure rotary jet grouting drill bit 5 is mounted on the outer side of the hexagonal cylinder 33. A third rotary drive 36 is mounted on the side of the hexagonal cylinder 33 away from the second rotary drive 35. A hydraulic impact drilling drill bit 4 is mounted on the output end of the third rotary drive 36. The third rotary drive 36 is used to switch the working positions of the two drill bits. By rotating its output end, the hydraulic impact drilling drill bit 4 and the high-pressure rotary jet grouting drill bit 5 can be quickly and smoothly interchanged, ensuring the continuity of operation when switching drill bits and avoiding mutual interference. The first rotary drive 32, the second rotary drive 35, and the third rotary drive 36 have the same internal structure and their sizes decrease sequentially. This compact hierarchical structural design integrates three different rotary drives within a limited space, ensuring that the original operation of the drilling rig is not affected and greatly improving the integration and space utilization of the equipment.

[0024] Specifically, the first rotary drive component 32 includes a base 326, which is fixedly connected to the side of the connecting seat 25 away from the adjusting seat 21. A slewing bearing 322 is rotatably connected inside the base 326, and a worm gear 323 is fixedly connected to the outside of the slewing bearing 322. A through mounting hole 324 is provided on the slewing bearing 322, and the mounting holes 324 are distributed in a ring at equal intervals on the outside of the slewing bearing 322 for installing and connecting external equipment, ensuring a stable connection, and being able to withstand the huge torque and impact force generated during drilling operations.

[0025] Specifically, a protective shell 327 is fixedly connected to the outer side of the base 326. A worm gear 325 is rotatably connected to the inner wall of the protective shell 327 through a bearing. The outer side of the worm gear 325 meshes with the outer side of the worm wheel 323 to form a worm wheel 323 and worm gear 325 transmission mechanism. This mechanism has a self-locking function and can automatically lock the position after adjustment to prevent the drill bit from shifting during operation, thus ensuring the accuracy and stability of drilling.

[0026] Specifically, a hydraulic motor 321 is installed on the outside of the protective housing 327. The end of the worm gear 325 near the hydraulic motor 321 passes through the protective housing 327 and extends to the outside of the protective housing 327. The output shaft of the hydraulic motor 321 and the end of the worm gear 325 located outside the protective housing 327 are fixedly connected by a coupling to provide stable and strong power output for the rotary drive component, ensuring that the drill bit moves smoothly and responds quickly during switching and adjustment.

[0027] Specifically, the protective housing 327 has a first connecting groove on the side near the base 326, and the base 326 has a second connecting groove on the side near the protective housing 327. The protective housing 327 communicates with the interior of the base 326 through the first and second connecting grooves, which facilitates the lubrication and maintenance of the internal transmission components, while also reducing the weight of the overall structure and improving the flexibility of the equipment. The worm gear 325 can mesh with the worm wheel 323 inside the base 326 through the first and second connecting grooves.

[0028] Specifically, a first bracket 37 is fixedly connected to the outside of the hexagonal tube 33. The first bracket 37 has an L-shaped design. The high-pressure jet grouting drill bit 5 is installed on the outside of the first bracket 37. The L-shaped design provides better lever arm support for the drill bit, enabling it to remain stable during high-pressure jet grouting operations and improving the uniformity and quality of grouting.

[0029] Specifically, the output end of the third rotary drive 36 is fixedly connected to a mounting plate 34, and the side of the mounting plate 34 away from the third rotary drive 36 is fixedly connected to a second bracket 38. The hydraulic impact drilling bit 4 is installed on the outside of the second bracket 38. The design of the mounting plate 34 increases the connection area, improves the stability of the impact drilling bit when subjected to high-frequency impact, and effectively reduces the wear and tear on the equipment caused by vibration.

[0030] Specifically, both the first support 37 and the second support 38 are made of high-strength steel structure, and the first support 37 and the second support 38 are staggered to allow for switching between different drill bits according to operational needs. This staggered design ensures that the movement trajectories of the two drill bits do not overlap when they are working or switching positions, fundamentally avoiding physical interference that may occur during the switching process. This makes the switching process very smooth, and drilling, grouting and other operations can be carried out continuously, greatly improving drilling efficiency. Example 2:

[0031] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The height adjustment assembly 2 includes an adjustment seat 21 positioned above the drive unit 1. Two symmetrically distributed cylinders 24 are mounted on the adjustment seat 21. The extension and retraction ends of both cylinders 24 are mounted on the top of the drive unit 1. By synchronously extending and retracting the two symmetrically distributed cylinders 24, the adjustment seat 21 and the entire drilling system above it can be smoothly raised and lowered, achieving precise adjustment of the drilling height. This design allows the drilling rig to flexibly adapt to the operational needs of different terrains, effectively reducing the impact of ground undulations on drilling accuracy and operational efficiency, and ensuring the smooth progress of drilling operations.

[0032] Specifically, three triangularly distributed guide posts 23 are fixedly connected to the outside of the drive device 1. Three through guide holes are opened at the top of the adjusting seat 21, and guide sleeves 22 are fixedly connected to the inner walls of the guide holes. The three guide sleeves 22 are fitted onto the outer sides of the corresponding guide posts 23. The three triangularly distributed guide posts 23 and the guide sleeves 22 cooperate to form a stable guiding system. When the cylinder 24 drives the adjusting seat 21 to rise and fall, the guide posts 23 ensure that the adjusting seat 21 always remains vertically raised and lowered, preventing skewness and further improving the verticality and accuracy of the drilling operation.

[0033] Specifically, a connecting seat 25 is fixedly connected to the outside of the adjusting seat 21 to securely connect the operation execution component 3, integrating the height adjustment function with the drill bit operation function into one, ensuring the rigidity and coordination of the overall structure.

[0034] The remaining structure is the same as that in Example 1.

[0035] The workflow of this invention is as follows: During drilling operations, the drive unit 1 can drive the entire drilling equipment to move in position. After moving to the work area, the positions of the two drill bits are adjusted according to the designed drilling position. Start cylinder 24. The extension and retraction of cylinder 24 drives the adjusting seat 21 to adjust up and down until the drill bit is adjusted to a suitable height and then stops. Under the action of the first rotary drive 32, the hexagonal cylinder 33 installed on its outer side can be rotated through the convex outer shell 31. The rotation of the hexagonal cylinder 33 moves the first bracket 37 and the second bracket 38 installed on its outer side, thereby adjusting the position of the hydraulic impact drilling bit 4 and the high-pressure rotary jet grouting bit 5. When the rotary drive is working, the hydraulic motor 321 drives the worm 325 to rotate through the output shaft. The rotation of the worm 325 drives the slewing bearing 322 inside the base 326 to rotate through the worm wheel 323. The rotation of the slewing bearing 322 drives the equipment mounted on the slewing bearing 322 to rotate, thereby adjusting the position and angle. The second rotary drive unit 35 and the third rotary drive unit 36 ​​can adjust the positions of the hydraulic impact drilling bit 4 and the high-pressure jet grouting bit 5 through the first bracket 37 and the second bracket 38 respectively, thereby performing impact drilling, jet mixing, concrete / grout delivery and synchronous grouting operations.

Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the motors will not be described in detail here.
