Description

Technical Field

[0001] This invention relates to the field of drilling rig technology, specifically a tracked multi-functional drilling rig. Background Art

[0002] A drilling rig is a mechanical device used in the exploration or development of mineral resources (including solid minerals, liquid minerals, gaseous minerals, etc.) to drive drilling tools into the ground and obtain physical geological data.

[0003] For example, patent CN118855409B discloses a tracked multi-functional mechanical core drill, including a tracked chassis with symmetrically arranged mounting frames fixedly installed on the chassis. A U-shaped plate is rotatably connected to the mounting frames. This invention relates to the field of core drilling technology. This invention adjusts the force of the striking plate in the striking assembly by adjusting the components, ensuring that the vibration generated by the striking plate hitting the hollow drill is just enough to expel the core from the hollow drill. This effectively prevents the core from getting stuck in the hollow drill and also avoids excessive striking force that could damage the hollow drill. Furthermore, the cleaning brush in the cleaning assembly cleans the surface of the hollow drill, preventing contaminants from affecting its rotation and the extraction and quality of the core. Simultaneously, when the hollow drill is raised, it facilitates cleaning of surface dirt, preventing it from affecting the striking plate's impact on the hollow drill. This effectively improves the working efficiency and reliability of the core drill.

[0004] Existing drilling rigs often result in uneven drilling areas and the drill bit not being perpendicular to the drilling area, leading to easy breakage of the drill rod and failing to meet user needs. Therefore, we propose a tracked multi-functional drilling rig. Summary of the Invention

[0005] The purpose of this invention is to provide a tracked multi-functional drilling rig to solve the problem mentioned in the background art that the drilling area is uneven and the drill bit cannot be perpendicular to the drilling area, which makes the drill rod of the drilling rig prone to breakage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tracked multi-functional drilling rig, comprising a walking track, a housing mounted on the top of the walking track, an electrical control box fixedly connected to the inner wall edge of the housing, a hydraulic oil tank fixedly connected to the inner wall of the housing away from the electrical control box, a hydraulic control valve fixedly connected to one side of the hydraulic oil tank, a water tank fixedly connected to one side of the hydraulic control valve, a radiator fixedly connected to one side of the electrical control box, and a motor pump fixedly connected inside the housing;

[0007] The output end of the motor pump is screwed with a pitch hydraulic rod, the output end of the pitch hydraulic rod is screwed with a connecting block, the outer wall of the connecting block is screwed with a pitch base that is fixedly connected to the inner wall of the chassis, and the top of the connecting block is fixedly connected with a sliding frame.

[0008] A sliding hydraulic rod is fixedly connected to the outer wall of the sliding frame, and a pitch sliding swing frame is fixedly connected to the output end of the sliding hydraulic rod. A limiting rod that is fixedly connected to the outer wall of the sliding frame is slidably connected to the inner wall of the pitch sliding swing frame.

[0009] Based on the above structure, the pitch hydraulic rod drives the connecting block to rotate around the pitch base as the center. The rotation of the connecting block drives the sliding frame to rotate synchronously, thereby adjusting the pitch angle of the thruster. Then, the sliding hydraulic rod drives the pitch sliding swing frame to slide along the outer wall of the limit rod.

[0010] Preferably, a working base is installed at the top of the pitch-sliding swing frame. A telescopic hydraulic rod is fixedly connected to the inner wall of the working base. A working frame that is slidably connected to the top of the working base is fixedly connected to the output end of the telescopic hydraulic rod. A thruster is fixedly connected to the inner wall of the working frame. A rock drill that is slidably connected to the top of the working frame is fixedly connected to the output end of the thruster. A drill rod is fixedly connected to the output end of the rock drill. A drill bit is installed at one end of the drill rod. A limiting base is fixedly connected to the bottom of the drill rod at the top of the working frame. A limiting frame that is sleeved on the outside of the drill rod is fixedly connected to the top of the limiting base. A cleaning frame is fixedly connected to one end of the working frame. A rotating ring is fitted into the outer wall of the drill bit, and a linkage frame is fixedly connected to the outer wall of the rotating ring and sleeved on the outside of the drill rod. A cleaning disc is fixedly connected to one end of the linkage frame, a scraper is fixedly connected to the outer wall of the cleaning disc, and a sweeping bar is fixedly connected to the side wall of the cleaning disc. During operation, the telescopic hydraulic rod drives the working frame to slide along the top of the working base, thereby moving the drill bit to the drilling area, so that the drill bit is perpendicular to the drilling area, realizing the rapid positioning operation of the drill bit in different construction environments. The rotation of the linkage frame drives the cleaning disc to rotate along the drilling area. The rotation of the cleaning disc scrapes away the dust in the drilling area through the scraper. At the same time, the rotation of the cleaning disc drives the sweeping bar to rotate synchronously, so as to keep the dust away from the drilling area.

[0011] Preferably, the pitch angle of the thruster is between +65° and -20°, the left and right swing angle of the thruster is ±180°, and the drilling depth of the thruster is 800mm. During operation, the pitch hydraulic rod drives the connecting block to rotate around the pitch base as the center. The rotation of the connecting block drives the sliding frame to rotate synchronously, thereby adjusting the pitch angle of the thruster. Then, the sliding hydraulic rod drives the pitch sliding swing frame to slide along the outer wall of the limit rod, thereby adjusting the sliding length of the thruster. Next, the telescopic hydraulic rod drives the working frame to slide along the top of the working base, thereby moving the drill bit to the drilling area, so that the drill bit is perpendicular to the drilling area, realizing the rapid positioning operation of the drill bit in different construction environments.

[0012] Preferably, the central axis of the limiting frame, cleaning frame, and cleaning disc coincides with the central axis of the drill rod. The scraper and sweeper are both arc-shaped. The scraper is radially distributed along the outer wall of the cleaning disc. There are three sets of sweepers. During operation, the linkage frame rotates, causing the cleaning disc to rotate along the drilling area. The rotation of the cleaning disc scrapes away the dust in the drilling area through the scraper. At the same time, the rotation of the cleaning disc causes the sweeper to rotate synchronously, making it easier to move the dust away from the drilling area.

[0013] Preferably, a screw rod passes through the inner wall of the limiting frame. A handwheel is fixedly connected to one end of the screw rod, and a rotating guide block is threadedly connected to the outer wall of the screw rod. A rotating guide plate is movably connected to the side wall of the rotating guide block. A linkage ring that is rotatably connected to the inner wall of the limiting frame is fixedly connected to the top of the rotating guide plate. A limiting guide post is fixedly connected to the inner wall of the linkage ring. A limiting clamp rod that is screwed to the inner wall of the limiting frame is movably connected to the outer wall of the limiting guide post. A limiting roller that is rotatably connected to the outer wall of the drill rod is screwed to one end of the limiting clamp rod. A guide strip is provided on the outer wall of the limiting roller. During operation, the rotating guide block slides through the rotating guide plate, causing the linkage ring to rotate. The rotation of the linkage ring causes the limiting guide post to rotate. The rotation of the limiting guide post causes the limiting clamp rod to swing. The swing of the limiting clamp rod causes the guide strip on the outer wall of the limiting roller to fit against the outer wall of the drill rod, thereby achieving the limiting operation of the drill rod and preventing the drill rod from breaking.

[0014] Preferably, three sets of limiting guide posts are provided. The limiting clamp rod forms a swing structure with the limiting guide post and the limiting frame through the linkage ring and the limiting guide post. The guide strip is spiral in shape. During operation, the linkage ring rotates, causing the three sets of limiting guide posts to rotate synchronously. The rotation of the limiting guide post causes the limiting clamp rod to swing. The swing of the limiting clamp rod causes the guide strip on the outer wall of the limiting roller to fit against the outer wall of the drill rod, thereby realizing the limiting operation of the drill rod and preventing the drill rod from breaking. It should be noted that by setting the spiral guide strip, the movement interference of the limiting roller is avoided when the drill rod is extended or retracted.

[0015] Preferably, a connecting pipe is fixedly connected to the outer wall of the cleaning frame, and a connecting interface connected to the water tank output pipe is fixedly connected to one end of the connecting pipe. A nozzle is fixedly connected to the outer wall of the connecting interface, and a cleaning brush is fixedly connected to the inner wall of the cleaning frame. During operation, cooling water in the water tank is injected into the connecting interface in the connecting pipe by a water pump. Then, the cooling water is sprayed out at high speed from the nozzle to perform water cooling operation on the drill rod and drill bit. After drilling is completed, the drill rod and drill bit move away from the drilling area. When the drill rod and drill bit retract, they come into contact with the cleaning brush, thereby cleaning the drill rod and drill bit.

[0016] Preferably, the cleaning brushes are distributed in a circular pattern at equal angles along the inner wall of the cleaning frame. During operation, when the drill rod and drill bit retract, they come into contact with the cleaning brushes, thereby performing a comprehensive cleaning operation on the drill rod and drill bit.

[0017] Preferably, a spring is fixedly connected to the inner wall of the linkage frame, a telescopic ring is fixedly connected to one end of the spring, a push block is fixedly connected to the outer wall of the telescopic ring, a connecting rod is screwed to the inner wall of the telescopic ring, a linkage slider is screwed to one end of the connecting rod, a limiting strip is slidably connected to the side wall of the linkage slider and fixedly connected to the inner wall of the linkage frame, and a linkage clamping block that fits against the outer wall of the drill rod is fixedly connected to the bottom end of the linkage slider. During operation, the spring drives the telescopic ring to slide through its own elastic force, the telescopic ring slides and drives the connecting rod to move, the connecting rod moves and drives the linkage slider to slide along the outer wall of the limiting strip, and the linkage slider slides and drives the linkage clamping block to fit tightly against the drill rod, so that the rotation of the drill rod drives the linkage frame to rotate synchronously.

[0018] Preferably, the connecting rods are provided in three sets. The linkage clamping block forms a clamping structure with the drill rod through the connecting rods and the linkage slider. During operation, the spring drives the telescopic ring to slide through its own elastic force. The sliding of the telescopic ring drives the three sets of connecting rods to move synchronously. The movement of the connecting rods drives the linkage slider to slide along the outer wall of the limiting strip. The sliding of the linkage slider drives the linkage clamping block to fit tightly with the drill rod, realizing the connection operation between the drill rod and the linkage frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a sliding frame, the pitch hydraulic rod drives the connecting block to rotate around the pitch base. The rotation of the connecting block drives the sliding frame to rotate synchronously, thereby adjusting the pitch angle of the thruster. Then, the sliding hydraulic rod drives the pitch sliding swing frame to slide along the outer wall of the limit rod, thereby adjusting the sliding length of the thruster. Next, the telescopic hydraulic rod drives the working frame to slide along the top of the working base, thereby moving the drill bit to the drilling area, so that the drill bit is perpendicular to the drilling area, realizing the rapid positioning operation of the drill bit in different construction environments.

[0021] 2. By setting limit rollers, the rotating guide block slides through the rotating guide plate, driving the linkage ring to rotate. The rotation of the linkage ring drives the three sets of limit guide posts to rotate synchronously. The rotation of the limit guide posts drives the limit clamp rod to swing. The swing of the limit clamp rod causes the guide strip on the outer wall of the limit roller to fit against the outer wall of the drill rod, thereby achieving the limit operation of the drill rod and preventing the drill rod from breaking. It should be noted that by setting a spiral guide strip, the movement of the limit roller is prevented from interfering with the extension and retraction of the drill rod.

[0022] 3. By setting up a cleaning disc, the spring drives the telescopic ring to slide through its own elasticity. The sliding of the telescopic ring drives the three sets of connecting rods to move synchronously. The movement of the connecting rods drives the linkage slider to slide along the outer wall of the limit strip. The sliding of the linkage slider causes the linkage clamp to fit tightly against the drill rod, so that the rotation of the drill rod drives the linkage frame to rotate synchronously. The rotation of the linkage frame drives the cleaning disc to rotate along the drilling area. The rotation of the cleaning disc scrapes away the dust in the drilling area through the scraper. At the same time, the rotation of the cleaning disc drives the sweeping bar to rotate synchronously, which makes it easier to move the dust away from the drilling area. It should be noted that the push block is set up to facilitate the drill rod to pass smoothly through the linkage frame.

[0023] 4. By setting up a cleaning brush, when the drill bit is drilling into the drilling area, it is necessary to cool the drill rod and drill bit. The water pump injects cooling water from the water tank into the connection interface in the connecting pipe. Then, the cooling water is sprayed out at high speed from the nozzle to cool the drill rod and drill bit. After drilling is completed, the drill rod and drill bit move away from the drilling area. When the drill rod and drill bit retract, they come into contact with the cleaning brush, thereby cleaning the drill rod and drill bit. Attached Figure Description

The linkage frame 11 rotates, driving the cleaning disc 12 to rotate along the drilling area. The rotation of the cleaning disc 12 scrapes away the dust in the drilling area through the scraper 1201.

[0051] The working principle of this invention is as follows: When using this tracked multi-functional drilling rig, firstly, the spatial position of the thruster 503 is positioned. The motor pump 206 drives the pitch hydraulic rod 3 to work. The working of the pitch hydraulic rod 3 drives the connecting block 301 to rotate around the pitch base 302. The rotation of the connecting block 301 drives the sliding frame 4 to rotate synchronously, thereby adjusting the pitch angle of the thruster 503. Next, the working of the sliding hydraulic rod 401 drives the pitch sliding swing frame 402 to slide along the outer wall of the limiting rod 403, thereby adjusting the sliding length of the thruster 503. Then, the working of the telescopic hydraulic rod 501 drives the working frame 502 to slide along the top of the working base 5, thereby moving the drill bit 602 to the drilling area, so that the drill bit 602 is perpendicular to the drilling area, realizing the rapid positioning operation of the drill bit 602 under different construction environments.

[0052] Next, the rock drill 6 operates by rotating the drill bit 602 via the drill rod 601. Then, within the limiting frame 8, the operator rotates the handwheel 802. The rotation of the handwheel 802 causes the rotating guide block 803 to slide via the screw 801. The sliding of the rotating guide block 803 causes the linkage ring 805 to rotate via the rotating guide plate 804. The rotation of the linkage ring 805 causes the three sets of limiting guide posts 806 to rotate synchronously. The rotation of the limiting guide posts 806 causes the limiting clamping rod 807 to swing. The swing of the limiting clamping rod 807 causes the guide strip 809 on the outer wall of the limiting roller 808 to fit against the outer wall of the drill rod 601, thereby limiting the operation of the drill rod 601 and preventing the drill rod 601 from breaking. It should be noted that by setting the spiral guide strip 809, the movement interference of the limiting roller 808 is prevented when the drill rod 601 extends or retracts.

[0053] Next, the pusher 503 drives the high-speed rotating drill bit 602 to drill in the drilling area. At this time, in the linkage frame 11, the spring 1101 drives the telescopic ring 1102 to slide through its own elasticity. The sliding of the telescopic ring 1102 drives the three sets of connecting rods 1104 to move synchronously. The movement of the connecting rods 1104 drives the linkage slider 1105 to slide along the outer wall of the limit strip 1106. The sliding of the linkage slider 1105 drives the linkage clamp 1107 to fit tightly against the drill rod 601, so that the rotation of the drill rod 601 drives the linkage frame 11 to rotate synchronously. The rotation of the linkage frame 11 drives the cleaning disc 12 to rotate along the drilling area. The rotation of the cleaning disc 12 scrapes away the dust in the drilling area through the scraper 1201. At the same time, the rotation of the cleaning disc 12 drives the sweeping strip 1202 to rotate synchronously, which facilitates the removal of dust from the drilling area. It should be noted that the pusher 1103 is set to facilitate the drill rod 601 to pass smoothly through the linkage frame 11.

[0054] Meanwhile, when the drill bit 602 drills into the drilling area, it is necessary to cool the drill rod 601 and the drill bit 602. The cooling water in the water tank 204 is injected into the connection interface 902 in the connecting pipe 901 by a water pump. Then, the cooling water is sprayed out at high speed from the nozzle 903 to perform water cooling on the drill rod 601 and the drill bit 602.

[0055] Finally, after drilling is completed, the drill rod 601 and drill bit 602 move away from the drilling area. When the drill rod 601 and drill bit 602 retract, they come into contact with the cleaning brush 904, thereby cleaning the drill rod 601 and drill bit 602.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
