Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering construction technology, specifically to adjustable water intake tunnel construction equipment and methods. Background Technology

[0002] Water intake tunnels, as underground water conveyance structures that traverse mountains, are key facilities in water conservancy projects connecting water sources (such as reservoirs, rivers, and lakes) with downstream water-using areas. Their core function is to achieve the safe and efficient transportation of water resources. During the construction of water intake tunnels, drilling operations are required to form construction channels with a predetermined outline. Currently, water-cooled drills are commonly used in the industry for this type of drilling.

[0003] In traditional construction processes, workers first need to use a water-cooled drill to drill inclined holes along the tunnel's designed outline. After the holes are formed, a wedge-shaped steel chisel must be manually inserted into the gap between the rock column and the hole wall. By striking the chisel, the rock column is separated from the rock mass. Then, a special tool is used to remove the detached rock column from the hole. This process requires the coordinated operation of multiple tools, which is not only cumbersome and labor-intensive but also inefficient, seriously affecting the construction progress.

[0004] In existing related technologies, such as the construction equipment disclosed in patent publication number CN120667010B, although attempts have been made to optimize the material removal method, it still relies on pry bars to strike and detach the rock column. This design not only easily causes the equipment's center of gravity to become unbalanced, increasing the difficulty of operation and safety risks, but also makes the overall layout of the equipment less compact due to the external auxiliary material removal structure. Summary of the Invention

[0005] The purpose of this invention is to provide adjustable water intake tunnel construction equipment and method for water conservancy projects, so as to solve the problem of inconvenient material unloading in existing equipment.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An adjustable water intake tunnel construction device for water conservancy projects includes a support mechanism on which a water mill frame is rotatably mounted. A water mill feed push rod is installed at the upper end of the water mill frame, and the output end of the water mill feed push rod is connected to a U-shaped frame.

The lower end of the water supply pipe extends into the cylinder plate. Further embodiment: The diameter adjustment unit includes an array of adjustment slide rods arranged inside the bottom frame. Each adjustment slide rod has an adjustment slider that slides on it. The lower end of the adjustment slider is connected to the cylinder plate via a clutch rod. The upper end of the adjustment slider is rotatably provided with a toggle shaft. A toggle disk is provided above the bottom frame. The toggle disk has multiple arc-shaped grooves arranged in an array. The arc-shaped grooves match the toggle shaft. The outer side of the toggle disk is rotatably connected to the outer ring of the bearing. The outer side of the outer ring of the bearing is fixedly connected to the bottom frame via a connecting side block. The toggle disk is connected to a drive component for rotating it. Further embodiment: The driving component includes an adjusting worm gear fixed to the outside of the dial, the outside of the adjusting worm gear meshing with an adjusting worm, the adjusting worm being coaxially mounted on a transmission shaft, one end of the transmission shaft being connected to the output end of an adjusting motor, the other end of the transmission shaft being rotatably connected to an adjusting bracket on the bottom frame, and the fixed end of the adjusting motor being connected to the bottom frame; Further solution: The actuating disc has a central hole at its center, and each cylinder plate has a central groove at its upper end. Multiple central grooves form a water injection hole coaxial with the central hole. Further solution: The angle adjustment mechanism includes a flip shaft disposed at both ends of the water mill base. The flip shaft is rotatably connected to the support mechanism. At least one end of the flip shaft is fixedly provided with a steering worm wheel. The upper side of the steering worm wheel meshes with a steering worm. The steering worm is connected to a steering motor for driving its rotation. The other end of the steering worm is rotatably connected to a steering bracket on the support mechanism. The base of the steering motor is also fixedly connected to the steering bracket. Further solution: The support mechanism includes two sets of base frames, each base frame is equipped with a set of wheels for displacement, each set of base frames has two vertical frames symmetrically arranged at the upper end, a first crossbeam is erected between two adjacent vertical frames, and the tops of the vertical frames on the two base frames are supported by a second crossbeam.

[0007] Usage instructions and procedures Equipment positioning and angle calibration: The equipment is moved to the predetermined construction position by the traveling wheels on the base frame, and the traveling wheels are locked to fix the equipment; the angle adjustment mechanism is activated, and the steering worm and steering worm gear are driven by the steering motor to drive the tilting shaft and water grinding frame to tilt, so that the water grinding cylinder is accurately aligned with the target drilling area.

[0008] Drilling operation implementation: Start the water mill motor to drive the drive shaft and water mill cylinder assembly to rotate at high speed; simultaneously start the water mill feed push rod to push the U-shaped frame and water mill base to move smoothly along the feed guide rod, so that the end of the high-speed rotating water mill cylinder assembly contacts the rock surface and continues to drill until a cavity of the target depth is formed; during the drilling process, the liquid supply mechanism is started simultaneously to continuously deliver cooling lubricant to the drilling area to reduce the operating temperature and reduce equipment wear and dust pollution.

[0009] Rock column unloading operation: After a single drilling is completed, the water mill feed push rod drives the water mill cylinder assembly to be removed from the rock; start the regulating motor to drive the transmission shaft, regulating worm gear and regulating worm wheel transmission, drive the dial to rotate, the arc groove on the dial pushes the regulating slider to move along the regulating slide rod, and then drives multiple cylinder plates to separate synchronously through the clutch lifting rod, and the rock column inside the cylinder falls off naturally under the action of gravity, completing the unloading operation.

[0010] The present invention has the following beneficial effects: The material removal efficiency is greatly improved and the labor intensity is significantly reduced: The innovative design of the detachable water mill cylinder group is adopted. The cylinder can be opened and closed precisely through the diameter adjustment unit. After a single drilling, there is no need to rely on additional auxiliary tools such as wedge steel chisels and pry bars. The cylinder plate can be separated and the rock column can be removed by motor drive alone, which completely solves the pain points of traditional equipment material removal that are time-consuming, labor-intensive and cumbersome to operate. At the same time, it avoids the problem of equipment center of gravity shift caused by the knocking of auxiliary structures, and greatly improves the safety and convenience of operation.

[0011] Construction adaptability and flexibility are significantly enhanced: the angle adjustment mechanism can achieve multi-angle precise adjustment of the drilling direction, adapting to the drilling needs of different locations and angles in water intake tunnels; the cylinder diameter can be flexibly adjusted through the adjustment unit to adapt to construction scenarios with different hole diameters, without the need to replace the entire set of drilling tools; the overall structure of the equipment is compact, with no external redundant auxiliary components, providing stronger accessibility and adaptability to working space in narrow tunnel construction environments, and greatly expanding the scope of application.

[0012] Extended equipment lifespan and optimized construction quality: The fluid supply mechanism enables precise delivery of cooling and lubricating fluid, continuously cooling and lubricating the drilling area, effectively reducing drill bit wear and thermal deformation, and extending the service life of core equipment components; at the same time, the fluid can suppress dust generated during drilling, improve the construction environment, and reduce the impact of dust on equipment and operators; the coordinated design of the feed slip ring and guide rod ensures the stability of the drilling process, improves the smoothness of the borehole wall and the accuracy of the borehole diameter, and guarantees construction quality.

[0013] Convenience of maintenance and guarantee of sample integrity: The detachable structure of the water mill cylinder not only facilitates the unloading of rock columns, but also provides convenience for internal maintenance of the equipment. It allows for quick inspection, cleaning and replacement of components such as the cylinder plate and clutch rod, reducing maintenance costs and downtime. In scenarios where rock sampling is required, the detachable cylinder can avoid the squeezing and damage to samples caused by traditional sampling methods, better ensuring sample integrity and providing reliable sample support for geological exploration.

[0016] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0017] refer to Figures 1-8 As shown, an adjustable water intake tunnel construction device for water conservancy projects includes a support mechanism. A water mill frame 200 is rotatably mounted on the support mechanism. A water mill feed push rod 201 is installed on the upper end of the water mill frame 200. The output end of the water mill feed push rod 201 is connected to a U-shaped frame 202. The lower end of the U-shaped frame 202 is connected to a water mill base 204. A water mill motor 205 is mounted on the water mill base 204. The output end of the water mill motor 205 is equipped with a water mill cylinder assembly 300 for drilling. The water mill frame 200 is connected to an angle adjustment mechanism for adjusting its angle, thereby adjusting the construction direction. The water mill cylinder assembly 300 includes four cylinder plates 301, which can also be set to other numbers. A bottom frame 305 and a top plate 321 are provided above the cylinder plates 301. The bottom frame 305 and the top plate 321 are connected by multiple connecting grids 322. The upper end of the top plate 321 is connected to the drive shaft 318, and the drive shaft 318 is connected to the output end of the water mill motor 205. The bottom frame 305 is provided with a diameter adjustment unit for adjusting the degree of closure of the multiple cylinder plates 301. The diameter adjustment unit can adjust the diameter of the cylinder formed by the multiple cylinder plates 301 to facilitate the unloading of materials later, which greatly facilitates the subsequent rock column detachment. The water grinding base 204 is symmetrically provided with feed slip rings 207 on both sides. The feed slip rings 207 are slidably mounted on the feed guide rods 206. The feed guide rods 206 are symmetrically arranged on both sides of the lower end of the water grinding frame 200. This allows the water grinding base 204 to slide smoothly along the feed guide rods 206 when it is fed, so as to improve the stability of its drilling. The vertical frame 100 is also equipped with a liquid supply mechanism to provide liquid for the operation of the water mill cylinder assembly 300. The continuous injection of water into the drilling position through the liquid supply structure helps to cool and lubricate, reduces dust, and also improves the life of the parts. The liquid supply mechanism includes a liquid storage cylinder 500 for storing liquid, which is mounted on a vertical frame 100. A liquid pump is installed inside the liquid storage cylinder 500, and a liquid supply pipe 501 is provided at the output end of the liquid pump. A buffer tank 502 is provided at the lower end of the water mill base 204. The buffer tank 502 has a through hole for the drive shaft 318 to pass through, and a sealing ring matching the drive shaft 318 is provided at the through hole. The drive shaft 318 has a hollow internal structure. The outer side of the drive shaft 318 is provided with a water inlet hole 319 that communicates with the buffer tank 502. The lower end of the drive shaft 318 is connected to a water supply pipe 320. The lower end of the water supply pipe 320 extends into the cylinder plate 301, thereby providing drilling fluid to the water mill cylinder assembly 300. The liquid is pumped into the buffer tank 502 through the liquid supply pipe 501 by a liquid pump. The liquid enters the drive shaft 318 along the water inlet hole 319, and then enters the cylinder body formed by the cylinder plate 301 along the drive shaft 318, thereby providing cooling and lubricating fluid for drilling. The diameter adjustment unit includes an array of adjustment slide rods 303 arranged inside the bottom frame 305. Each adjustment slide rod 303 has an adjustment slider 302 slidably mounted on it. The lower end of the adjustment slider 302 is connected to the cylinder plate 301 via a clutch rod 316. The upper end of the adjustment slider 302 is rotatably equipped with a toggle shaft 309. A toggle disc 308 is provided above the bottom frame 305. The toggle disc 308 has a plurality of arc-shaped grooves 310 arranged in an array. The arc-shaped grooves 310 match the toggle shaft 309. The outer side of the toggle disc 308 is connected to a bearing. The outer ring 304 is rotatably connected, and the outer side of the bearing outer ring 304 is fixedly connected to the bottom frame 305 through the connecting side block 306. The actuating disk 308 is connected to the driving component for rotating it. The driving component can drive the actuating disk 308 to rotate. The arc groove 310 on the actuating disk 308 pushes the actuating shaft 309, thereby causing the adjusting slider 302 to move along the adjusting slider 303, thereby causing multiple cylinder plates 301 to close and open. When closed, they form a complete cylinder structure. When opened, they can facilitate the detachment of rock columns in the cylinder structure. The operation is simple. The driving component includes an adjusting worm gear 307 fixed on the outside of the dial 308. The outside of the adjusting worm gear 307 meshes with the adjusting worm 314. The adjusting worm 314 is coaxially mounted on the transmission shaft 313. One end of the transmission shaft 313 is connected to the output end of the adjusting motor 312, and the other end of the transmission shaft 313 is rotatably connected to the adjusting bracket 315 on the bottom frame 305. The fixed end of the adjusting motor 312 is connected to the bottom frame 305. The adjusting motor 312 drives the transmission shaft 313 and the adjusting worm 314 to rotate. The adjusting worm 314 matches the central slot 317, thereby driving the dial 308 to rotate and providing power for the adjustment of the diameter adjustment unit. The actuating disc 308 has a central hole 311 at its center, and each cylindrical plate 301 has a central groove 317 at its upper end. Multiple central grooves 317 form a water injection hole coaxial with the central hole 311. The angle adjustment mechanism includes a flip shaft 203 disposed at both ends of the water mill base 204. The flip shaft 203 is rotatably connected to the support mechanism. At least one end of the flip shaft 203 is fixedly provided with a steering worm gear 401. The upper side of the steering worm gear 401 meshes with a steering worm 402. The steering worm 402 is connected to a steering motor 403 for driving its rotation. The other end of the steering worm 402 is rotatably connected to a steering bracket 400 on the support mechanism. The base of the steering motor 403 is also fixedly connected to the steering bracket 400. The steering motor 403 drives the steering worm 402 to rotate. The steering worm 402 matches the steering worm gear 401 to drive the flip shaft 203 to rotate, thereby driving the entire water mill frame 200 to flip, thus completing the angle adjustment. Here, in order to improve the protection performance, a dustproof shell is provided at the position of the steering worm gear 401 and the steering worm 402. The support mechanism includes two sets of base frames 102. The base frames 102 are equipped with a set of traveling wheels 103 for displacement. Each set of base frames 102 has two vertical frames 100 symmetrically arranged at the upper end. A first crossbeam 101 is erected between two adjacent vertical frames 100. The tops of the vertical frames 100 on the two base frames 102 are supported by a second crossbeam 104.

[0018] Working principle: In actual use, the equipment is moved to the predetermined position by the walking wheel set 103, and then the position of the equipment is locked. Then, the angle adjustment mechanism is used to align the water grinding cylinder set 300 with the target area. The water grinding motor 205 drives the water grinding cylinder set 300 to rotate at high speed. During the rotation, the U-shaped frame 202 is pushed to move by the water grinding feed push rod 201. The water mill motor 205 drives the water mill cylinder assembly 300 to rotate. The end of the water mill cylinder assembly 300 rotates at high speed on the rock surface. The water mill feed push rod 201 drives the U-shaped frame 202 and the water mill base 204 to move, thereby enabling the water mill cylinder assembly 300 to drill a cavity at the target depth in the rock. At the same time as drilling, the liquid pump sends liquid into the buffer tank 502 through the liquid supply pipe 501. The liquid enters the drive shaft 318 through the water inlet hole 319, and then flows along the drive shaft 31... 8. The water mill cylinder assembly 300 is inserted into the cylinder body formed by the cylinder plate 301 to provide cooling and lubricating fluid for drilling. After a single drilling is completed, the water mill cylinder assembly 300 is removed from the rock. Then, the drive unit can drive the actuating disk 308 to rotate. The arc groove 310 on the actuating disk 308 pushes the actuating shaft 309, thereby causing the adjusting slider 302 to move along the adjusting slide rod 303, thereby separating the multiple cylinder plates 301. After separation, it is convenient for the rock column in the cylinder structure to fall off. The operation is simple.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
