Description

Technical Field

[0001] This utility model relates to the technical field of slope reinforcement engineering equipment, and more specifically to an array-type multi-hole continuous drilling high-efficiency slope drilling machine. Background Technology

[0002] Slope reinforcement is an important civil engineering measure aimed at enhancing slope stability, preventing geological disasters such as landslides and collapses, and protecting the safety of residents, buildings, and roads below the slope. Many abandoned mine revegetation projects involve this, and the slopes of these old abandoned mines are often steep rock slopes, requiring the drilling of plant growth holes. Previously, the traditional method involved manual drilling using handheld rock drills on these steep slopes under the protection of safety ropes, a dangerous and highly inefficient process.

[0003] Most slope protection methods rely on slope drilling, which necessitates the use of slope drilling rigs. There are many types of slope drilling rigs on the market, such as the ZL201420053172.0 horizontal drilling rig for high-pressure jet grouting of railway subgrade slopes. This rig includes a power unit consisting of a hydraulic pump station; an execution unit consisting of a rotary hydraulic motor, a floating power head, a feed and pullback hydraulic motor, a chain-type feed and pullback mechanism, a drill rod clamping and unhooking mechanism, a swivel, and a drill frame plate; and an operation unit consisting of a hydraulic control circuit, an operating handle, and a display. The horizontal drilling rig is equipped with parallel guide rails laid and fixed along the subgrade slope. The drill frame plate of the horizontal drilling rig has supports to keep it horizontal. The bottom of each support has at least two rollers on each side of the parallel guide rails, which roll and engage with the corresponding guide rails.

[0004] The aforementioned slope drilling rigs represent mainstream slope drilling rigs. They are all single-bit drilling machines. After drilling one spot, they move to the next and continue drilling. They are more suitable for slope protection methods with low drilling density. However, for the aforementioned wire mesh shotcrete slope protection, the drilling density on the prepared slope is relatively high. Using the aforementioned slope drilling rigs is very inefficient and the project progress is slow.

[0005] Furthermore, the drilling angle for slopes typically ranges from 15° to 75°, with the specific angle chosen based on the actual conditions and design requirements of the project. However, the aforementioned slope drilling rigs can only drill horizontally, with a single angle that cannot be adjusted as needed, thus failing to meet the requirements for construction drilling. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned defects of the existing technology and provide a high-efficiency slope drilling rig that is mobile, has a stable chassis, adjustable drilling angle, array-type drilling rigs, and can drill multiple holes in one go.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an array-type multi-hole continuous drilling high-efficiency slope drilling rig, comprising a support platform, a pair of front wheels arranged in a left-right row on the front side of the support platform, a pair of rear wheels arranged in a left-right row on the rear side of the support platform, and a pair of hydraulic winches arranged in a left-right row on the front side of the support platform. The characteristic feature is that several swing beams are hinged at equal intervals between the two hydraulic winches on the front side of the support platform, and a lifting cylinder is respectively provided between each swing beam and the support platform. Each swing beam is respectively provided with a lifting cylinder that extends along its length... The system comprises a large compensation slide rail extending along its length, each of which has a slide beam slidably mounted parallel to it. Each slide beam is connected to a large compensation cylinder via a corresponding swing beam. Each slide beam has a small compensation slide rail extending along its length, and each small compensation slide rail has a motor seat that slides with it. Each motor seat is connected to a small compensation cylinder via a corresponding slide beam. Each motor seat has a hydraulic motor, and each hydraulic motor has a drill rod axially mounted on its motor shaft.

[0008] This utility model has many advantages: (1) It is flexible to move. The hydraulic winch pulls the front and rear wheels and drills holes in a row from bottom to top or from top to bottom. (2) The chassis is stable. The four wheels land smoothly. The two hydraulic winches are distributed left and right, lowering the center of gravity and balancing left and right, which provides a guarantee for stable drilling. (3) The drilling angle is adjustable. The lifting cylinder adjusts the tilt angle of the swing beam, and then adjusts the tilt angle of the drill rod to ensure that the drilling angle is determined according to the actual engineering conditions and design requirements. (4) It can drill multiple holes in one go. The drilling machines are arranged in an array. The number of drilling machines should not be too many or too few. 3 to 8 groups are the best. Multiple groups of drilling machines are distributed in a regular manner and drill holes at the same time, which is neat, orderly and efficient.

[0009] Preferably, each of the slide beams is provided with a guide ring on the side where the free end of the drill pipe is located.

[0010] The guide ring serves to support the drill pipe from the front, enhancing drilling stability and distributing the operational stress on the pipe end to prevent breakage.

[0011] Preferably, each of the slide beams is provided with a small compensation groove extending along its length, wherein a small compensation cylinder is embedded in the small compensation groove.

[0012] The slide beam is designed as a frame structure, allowing the small compensating cylinder to be inserted and fixed in place without affecting the operation of other mechanisms, resulting in a more rational structural design. The hinge seat below the motor base can also extend into the small compensating slide groove and hinge with the cylinder shaft of the small compensating cylinder.

[0013] Preferably, each of the sliding beams is also provided with a pair of sliding rods arranged in a left-right row. The two sliding rods are arranged parallel to the small compensation slide rail. Each of the sliding rods is provided with a sliding sleeve that slides with it. The two sliding sleeves are placed on their corresponding motor seats, one on the left and one on the right.

[0014] These sliding rods are used to assist the motor mount in sliding, stabilize the drilling state, prevent wobbling, and share the recoil force of the small compensation cylinder during drilling.

[0015] Preferably, each of the swing beams is provided with a large compensation groove extending along its length, wherein the large compensation cylinder is embedded in the large compensation groove.

[0016] The swing beam is designed as a frame structure, allowing the large compensation cylinder to be inserted and fixed in place without affecting the operation of other mechanisms, resulting in a more rational structural design. The hinge seat under the sliding beam can also extend into the large compensation groove and hinge with the cylinder shaft of the large compensation cylinder.

[0017] Preferably, the front side of the support platform is provided with a pair of extension platforms extending to the left and right sides respectively, and each extension platform is provided with a hydraulic winch on its upper side.

[0018] Two hydraulic winches are distributed left and right, lowering the center of gravity and balancing left and right sides, ensuring stable drilling.

[0019] Preferably, each of the extended platforms is provided with a front wheel on its lower side, and the wheel axle distance between the two front wheels is greater than the wheel axle distance between the two rear wheels.

[0020] The axle spacing of the two front wheels and the two rear wheels is different. This design makes the four wheels arranged in a trapezoidal shape rather than a rectangular shape, which makes them more stable on the hillside and prevents them from tipping over.

[0021] Beneficial effects: (1) Flexible movement, the hydraulic winch pulls the front and rear wheels, drilling sequentially from bottom to top or top to bottom; (2) Stable chassis, the four wheels land smoothly, the two hydraulic winches are distributed left and right, lowering the center of gravity and balancing left and right, providing a guarantee for stable drilling; (3) Adjustable drilling angle, the lifting cylinder adjusts the tilt angle of the swing beam, and then adjusts the tilt angle of the drill rod, ensuring that the drilling angle is determined by the actual engineering conditions and design requirements; (4) High efficiency and multiple holes at once, the drilling rigs are arranged in an array, and multiple groups of drilling rigs are distributed in a regular manner and drill holes at the same time, which is neat, orderly and efficient.

[0027] like Figure 2 As shown, four swing beams 6 are hinged at equal intervals between two hydraulic winches 4 on the front side of the support platform 1. Each swing beam 6 is connected to the support platform 1 by a lifting cylinder 7. Each swing beam 6 is equipped with a large compensation slide rail 8 extending along its length. Each large compensation slide rail 8 is slidably equipped with a slide beam 9 arranged parallel to it. Each slide beam 9 is connected to a large compensation cylinder 10 between itself and its corresponding swing beam 6. Each slide beam 9 is equipped with a small compensation slide rail 11 extending along its length. Each small compensation slide rail 11 is equipped with a motor seat 12 that slides with it. Each motor seat 12 is connected to a small compensation cylinder 13 between itself and its corresponding slide beam 9. Each motor seat 12 is equipped with a hydraulic motor 14. Each hydraulic motor 14 has a drill rod 15 axially connected to its motor shaft. A drill bit seat is provided on the free end of the drill rod 15. Each slide beam 9 has a guide ring 16 on the side where the free end of the drill pipe 15 is located.

[0028] Each slide beam 9 is provided with a small compensation groove 19 extending along its length, wherein the small compensation cylinder 13 is embedded in the small compensation groove 19.

[0031] Usage: The drilling angle and drill bit are determined based on the actual conditions and design requirements of the slope protection project. All drill bits are pre-installed in the drill bit holders on the free end of the drill rod, and the steel cables of the hydraulic winches on both sides are pre-fixed to the top of the slope. Then, based on the angle of the prepared slope slope and the known drilling angle, the lifting cylinder is calculated to lift the drill rod to tilt the swing beam, indirectly through components such as the sliding beam, so that the drill rod angle reaches the required tilt. Then, the hydraulic winch is activated to pull the drill to the specific drilling position. The large compensation cylinder pushes the sliding beam forward, allowing the drill bit to reach the soil layer. Then, the hydraulic motor is activated, and the small compensation cylinder pushes the motor seat, drilling while advancing, drilling one row of holes at a time. After drilling one row, the position is moved, and the above process is repeated until the entire row of holes is completed.
