In the utility model, the installation mechanism is designed to solve the problem, and the clamping block and the clamping groove of the installation mechanism form a precise positioning structure in the high-altitude gust scene. The platform can be quickly clamped into the corresponding groove of the rotary hinge seat, and it is not necessary to repeatedly adjust the boom, thereby shortening the installation time and avoiding the deformation of the hole position due to knocking. When the drill rod drills hard rock layers and generates high-frequency vibration, the clamping block cooperates with the rubber non-slip pad to buffer the vibration energy and weaken the influence of the alternating stress on the connecting bolt.

[0002] The prefabricated high-altitude drilling rig attached to the boom is a specialized piece of equipment suitable for high-altitude slope anchor bolt and anchor cable construction. It mainly consists of a boom connection module, a prefabricated working platform, and a hydraulic drilling system. It is connected to the top of the boom through a 360° rotating hinge seat and a double-cylinder hydraulic leveling mechanism, which can realize full-circumference rotation of the working platform and real-time level calibration. The working side of the platform integrates a hydraulic drilling system with ±30° pitch adjustment, including a power station, power head, and drill rod. It can accurately adapt to slopes with different inclination angles, expand the working functions of the boom, solve the problems of stability and accuracy of high-altitude drilling, and greatly improve the safety and efficiency of high and steep slope support construction.

[0003] In existing high-altitude scenarios for anchoring construction on steep mountain slopes, aligning the mounting holes of the slewing hinge seat with the platform is extremely inconvenient: the platform is suspended in the air and sways continuously due to 3-4 level gusts of wind; the holes without positioning structures require repeated fine adjustments to the boom posture; workers need to bend over to stabilize the platform and visually calibrate multiple sets of mounting holes; each alignment takes a long time; and the holes are prone to collision and deformation due to limited operating space. To address this, this utility model proposes a prefabricated high-altitude drilling rig attached to the boom. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4This utility model provides a technical solution: a prefabricated high-altitude drilling rig attached to a boom, including a boom 2 mounted on a crane 1, and a hydraulic drilling system 5 located at the end of the boom 2 and at the top of the crane 1. The boom 2 extends to the target working height and horizontal position, realizing flexible adjustment of the working position. A connecting mechanism 3 is provided at the end of the boom 2. The connecting mechanism 3 consists of a rotary hinge seat 31 and a double-cylinder hydraulic leveling mechanism 32. The rotary hinge seat 31 is located between the boom 2 and the hydraulic drilling system 5, connecting the top of the boom 2 and the platform 51, realizing 360° circumferential rotation of the platform to adapt to the working angle of different hole positions. The double-cylinder hydraulic leveling mechanism 32 is located on both sides of the rotary hinge seat 31. The tilt of platform 51 is adjusted to match the slope angle, ensuring drilling accuracy. An installation mechanism 4 is provided at the contact point between the rotary hinge seat 31 and the hydraulic drilling system 5. The installation mechanism 4 consists of a rubber anti-slip pad 41, a locking block 42, a locking groove 43, and multiple limiting components 44. The locking block 42 is located at the bottom of the hydraulic drilling system 5, and the rubber anti-slip pad 41 is fitted onto the surface of the locking block 42. The rubber anti-slip pad 41 buffers drill rod vibration, enhances the anti-slip properties of the contact surface between platform 51 and rotary hinge seat 31, and reduces connection loosening. The locking groove 43 is located at the top of the rotary hinge seat 31, and multiple limiting components 44 are located on the surface of the locking block 42 and inside the locking groove 43. The locking groove 43 and locking block 42 secure the platform 51. 1. The rotary hinge seat 31 provides rapid and precise positioning, simplifying hole alignment. The surface of the locking block 42 is in contact with the inner wall of the slot 43. The cross-section of the locking block 42 is circular. During the installation of the rotary hinge seat 31 and the platform 51, the locking block 42 and the slot 43 are pre-aligned to ensure pre-alignment. Then, the hydraulic drilling system 5 is adjusted as a whole. When multiple limit blocks 441 are aligned with multiple limit slots 442, the hydraulic drilling system 5 moves downward by gravity, causing the locking block 42 to engage with the inner side of the slot 43. The contact surface of the rotary hinge seat 31 is in contact with the rubber anti-slip pad 41. The bolts are then inserted to complete the assembly operation between the rotary hinge seat 31 and the platform 51. The limiting component 44 consists of limit blocks 441 and limit slots 442. 441 is fixed to the surface of the locking block 42. The limiting groove 442 is opened inside the locking groove 43. The limiting component 44 constrains the relative displacement of the platform 51 and the rotary hinge seat 31 to prevent misalignment during operation. Multiple mounting holes are opened on the inner top of the rotary hinge seat 31, the inner side of the rubber anti-slip pad 41, and the bottom of the hydraulic drilling system 5. Bolts pass through the inner side of the mounting holes. The hydraulic drilling system 5 consists of a platform 51, a guardrail 52, a drilling power head 53, a drill rod 54, and a power mechanism 55. The guardrail 52 is installed on the platform 51, the drilling power head 53 is set on the platform 51, the drill rod 54 is set in front of the drilling power head 53, and the power mechanism 55 is set inside the platform 51. The platform 51 carries the drilling equipment and provides a high-altitude operation space.The guardrail 52 ensures the safety of personnel working at height. The drilling power head 53 receives power from the power mechanism 55, driving the drill rod 54 to rotate. The drill rod 54 directly contacts the rock mass to complete the drilling operation for slope anchoring. The power mechanism 55 consists of a hydraulic pump and hydraulic pipelines. The hydraulic pipelines are mounted on the hydraulic pump. The power mechanism 55 provides driving power to the drilling power head, supporting the rotation and feed of the drill rod 54. Valves are installed on the hydraulic pump.

[0016] The working principle and usage process of this utility model: During the operation of the assembled high-altitude drilling rig attached to the boom: Crane 1 travels to the slope construction area, deploys outriggers to stabilize the vehicle body; controls boom 2 to extend to the target working height and horizontal position; The rotary hinge seat 31 of the connecting mechanism 3 is fixed to the top of the boom 2. The platform 51 of the hydraulic drilling system 5 is hoisted. The rotary hinge seat 31 is quickly aligned with the mounting mechanism 4 through the locking block 42 and the locking groove 43. The limiting component 44 engages synchronously to complete the positioning. The rubber anti-slip pad 41 enhances the stability of the contact surface. Start the dual-cylinder hydraulic leveling mechanism 32 and adjust the platform 51 to a suitable position for drilling according to the slope angle; The power mechanism 55 drives the drilling power head 53, which in turn drives the drill rod 54 to rotate and feed, completing the slope anchoring drilling. The vibration during operation is buffered by the rubber anti-slip pad 41 of the installation mechanism 4 to prevent the connection from loosening. After drilling is completed, retract drill rod 54 and retract boom 2.
