Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a large-diameter core wall drilling equipment. Background Art

[0002] The core wall of a dam is a structural design in hydraulic structures, especially in earth-rock dams. The core wall is the central part of the dam body, which is isolated from the dam shell (the outer part of the dam body) on both sides and usually has a small permeability to prevent water from penetrating from the central part of the dam body to the sides. The function of the core wall is mainly to improve the overall stability of the dam body because it can reduce the impact of water pressure on the dam body. The core wall is usually made of non-permeable materials (such as clay), which can effectively intercept water molecules and prevent them from passing through the dam body.

[0003] In order to meet specific engineering requirements, such as installing drainage pipes, temperature sensors or other monitoring equipment to ensure the safety of the dam and the need for monitoring, the core wall needs to be perforated. Since the core wall is usually made of materials such as soil, clay, sand and gravel, these materials will be cut or broken during drilling, resulting in debris. These debris will affect the installation of drainage pipes and sensors. Summary of the invention

A motor seat 404 is fixedly installed on the body 1, and a motor 405 is fixedly installed on the motor seat 404. The output shaft of the motor 405 is fixedly connected to one of the pulleys of the transmission belt 403. The motor 405 is started to drive the transmission belt 403 to rotate, and then the two screw rods 402 are driven to rotate, so that the driving plate 406 can be driven to move inside the slide groove 401, thereby driving the punching device or the cleaning device to move.

[0029] The punching device includes a punching motor 5 fixedly mounted on one of the driving plates 406, a drill bit 501 rotatably mounted on one of the driving plates 406, and an output shaft of the punching motor 5 is coaxially fixedly connected with the drill bit 501. The punching motor 5 is started to drive the drill bit 501 to rotate, and the feed mechanism drives the drill bit 501 to move, so that the core wall can be punched.

[0030] The cleaning mechanism includes an adjustable roller brush assembly and an air blowing assembly. The adjustable roller brush assembly is equipped with a plurality of roller brushes 703. The adjustable roller brush assembly controls the distance between the roller brush and the inner wall of the hole. The air blowing assembly blows out the impurities in the hole. The roller brush 703 can clean the inner wall of the hole, so that the dust and debris attached to the inside of the hole fall off from the inner wall of the hole, and the air blowing assembly discharges the dust and debris to the outside of the hole.

[0031] Furthermore, the cleaning mechanism includes a cleaning motor 6 fixedly mounted on one of the driving plates 406, a transmission shaft 601 rotatably mounted on one of the driving plates 406, and an installation box 602 coaxially fixedly connected to the transmission shaft 601 and fixedly mounted on the transmission shaft 601.

At this time, the first fan 8 is started, and the first fan 8 will blow air in the direction away from the hole outlet. At this time, the impurities at the bottom of the hole will be affected by the wind force of the first fan 8. After the wind blown by the first fan 8 contacts the bottom of the hole, it will move in the opposite direction, thereby driving the impurities to move toward the hole opening. Then, the second fan 801 is started, and the second fan 801 will blow air in the direction close to the hole opening, thereby exerting a force on the impurities to move toward the direction close to the hole opening, thereby blowing the impurities to the outside of the hole opening, and completing the discharge of the impurities.

[0034] Working principle: Start the motor 405 to drive the two screw rods 402 to rotate, so that the punching device can be driven to move to a position close to the core wall and make the drill bit 501 contact the wall. After adjusting the punching position, start the punching motor 5 to drive the drill bit 501 to rotate, and drive the drill bit 501 to move to the inside of the core wall through the feeding mechanism, so that the core wall can be punched. After the punching is completed, the drill bit 501 is moved out of the punched hole again through the feeding mechanism. Then start the driving motor to drive the second gear 301 to rotate, so that the first gear 3 can be driven to rotate, and then drive the conversion column 2 to rotate. Then the drill bit 501 is moved out from the position coaxial with the hole, and after the conversion column 2 is rotated 180 degrees, the installation box 602 is moved to a position coaxial with the hole.
