Technical Field
[0001] This utility model relates to the field of drilling rig anti-jamming technology, specifically a drilling rig anti-jamming device. Background Technology
[0002] A drilling rig is a highly efficient drilling device widely used in mining, geological exploration, and engineering construction. It drives the drill bit to rotate through a transmission structure such as an electric motor to achieve the purpose of drilling. It is mainly used in the exploration or development of mineral resources (including solid minerals, liquid minerals, gaseous minerals, etc.). By driving the drill bit to drill underground, it obtains physical geological data. When drilling into rocks, if the pressure is too high or the drilling direction is incorrect, the drill bit is easy to get stuck in the borehole.
[0003] Traditional methods require removing the drill bit and using tools to tap or vibrate it to loosen and remove a stuck drill bit. This is not only inconvenient but also requires carrying extra tools, disrupting the drilling process. Therefore, we propose a drilling rig anti-jamming device. Utility Model Content
[0004] The purpose of this utility model is to provide a drill bit anti-jamming device. By fixing an upper ring block and a lower ring block on the outer ring of the drill rod, and placing a sliding striking block on the outer ring of the drill rod between the upper ring block and the lower ring block, when the drill bit is jammed, the striking block can be held and moved up and down back and forth, acting on the surface of the upper ring block and the lower ring block, thereby transmitting the vibration to the drill bit and causing it to loosen. This eliminates the need to carry many extra tools and makes it convenient and quick to release the jammed drill bit, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling rig anti-jamming device, comprising a base, a support plate, and an electric drill. The support plate is fixedly mounted on the top of the base. Electric push rods are installed on both sides of the surface of the support plate. The protruding ends of the electric push rods extend through to the bottom of the support plate, and a lifting plate is horizontally fixed at the end of the protruding ends of the electric push rods. The electric drill is mounted on the surface of the lifting plate. A drill bit is mounted on the output shaft of the electric drill via a drill rod drive. An upper ring block is fixedly mounted around the outer ring of the drill rod near the top, and a lower ring block is fixedly mounted around the outer ring of the drill rod at the lower middle position. A striking block is slidably fitted onto the outer ring of the drill rod between the upper and lower ring blocks.
[0006] By adopting the above technical solution, when the drill bit gets stuck during drilling, the upper and lower ring blocks are struck by the up-and-down movement of the striking block, which transmits the force to the drill bit position, making it easy to vibrate and loosen, thus releasing the stuck state, without the need to carry additional tools.
[0007] Optionally, a rubber sleeve is also provided, with two rubber sleeves of the same size.
[0008] By adopting the above technical solution, before drilling, the rubber sleeve can be placed on the outer ring of the drill rod above and below the striking block to lock the striking block and prevent it from being in an unlocked and wobbly state when the drill rod rotates.
[0009] Optionally, the rubber sleeve has a side opening on its side, through which the rubber sleeve can be fastened to the outer ring of the drill rod.
[0010] By adopting the above technical solution, the rubber sleeve can deform to enlarge the side opening, thereby getting stuck on the outer ring of the drill pipe.
[0011] Optionally, a connector is fixed below the output shaft of the electric drill, and the drill rod is connected and locked to the output shaft of the electric drill through the connector.
[0012] By adopting the above technical solution, the drill pipe is inserted into the joint from the top, and the drill pipe is locked by the joint.
[0013] Optionally, a perforation is provided in the middle of the striking block, through which the drill rod passes.
[0014] Optionally, the diameter of the striking block is larger than the diameters of the upper and lower ring blocks, and the upper and lower ring blocks have the same diameter.
[0015] By adopting the above technical solution, when holding the striking block and moving it up and down to strike the upper and lower ring blocks, the hand is less likely to be trapped between the striking block and the upper or lower ring block.
[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0017] 1. The technical solution of this application fixes an upper ring block and a lower ring block on the outer ring of the drill rod, and places a sliding striking block on the outer ring of the drill rod between the upper ring block and the lower ring block. When the drill bit is stuck, the striking block can be held and moved up and down to act on the surface of the upper ring block and the lower ring block, thereby transmitting to the drill bit to make it vibrate and loosen. This eliminates the need to carry many extra tools and makes it convenient and quick to release the stuck state of the drill bit.
[0018] 2. The technical solution of this application has an additional rubber sleeve. The two rubber sleeves are used to lock the striking block above and below, so that the striking block will not shake during normal operation when the drill rod and drill bit are driven to rotate.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a drilling rig anti-jamming device, including a base 1, a support plate 2 and an electric drill 4. The support plate 2 is fixed above the base 1 and is parallel to the surface of the base 1. Electric push rods 21 are installed on both sides of the surface of the support plate 2. The protruding end of the electric push rod 21 extends through to the bottom of the support plate 2, and a lifting plate 3 is horizontally fixed at the end of the protruding end of the electric push rod 21. The electric drill 4 is installed on the surface of the lifting plate 3. When the electric push rod 21 is raised or lowered, it can drive the lifting plate 3 and the electric drill 4 to raise or lower their height.
[0025] The output shaft of the electric drill 4 passes under the lifting plate 3, and a connector 41 is fixed below the output shaft of the electric drill 4. The lower part of the output shaft is connected to the drill rod 51 through the connector 41. The drill bit 5 is fixed at the bottom end of the drill rod 51. When the drill rod 51 is inserted into the connector 41, the locking bolt located on the side of the connector 41 is tightened to lock the drill rod 51. When the electric drill 4 is working, it drives the drill rod 51 and the drill bit 5 to rotate. An opening is provided on the surface of the base 1 directly below the drill bit 5. When the drill rod 51 and the drill bit 5 are driven to rotate, the electric drill 4 is driven to lower the height, so that the drill bit 5 can pass through the base 1 to perform drilling work.
[0026] An upper ring block 512 is fixed around the outer ring of the drill rod 51 towards the top, and a lower ring block 511 is fixed around the outer ring of the drill rod 51 slightly below the middle. The upper ring block 512 and the lower ring block 511 have the same diameter. A striking block 6 is slidably fitted on the outer ring of the drill rod 51 between the upper ring block 512 and the lower ring block 511. A through hole 61 is opened in the middle of the striking block 6. The drill rod 51 passes through the striking block 6 through the through hole 61. When the drill bit 5 is stuck, the machine can be stopped first, and then the striking block 6 can be held and moved up and down to strike the surfaces of the upper ring block 512 and the lower ring block 511, and the striking force is transmitted to the drill bit 5, making it easy to be vibrated and loosened, thereby releasing the stuck state. If necessary, before striking, the locking of the joint 41 to the drill rod 51 can be released first, so that there is a certain amount of shaking between the top of the drill rod 51 and the joint 41, which makes it easier to strike and loosen the drill bit 5 and release the stuck state.
[0027] The diameter of the striking block 6 is larger than the diameter of the upper ring block 512 and the lower ring block 511. With the above arrangement, when the striking block 6 is held on the outer ring and moved up and down, fingers and other parts are less likely to be caught between the striking block 6 and the upper ring block 512 or the lower ring block 511 and get injured.
[0028] When the drill rod 51 and drill bit 5 rotate, the striking block 6 tends to move around the outer ring of the drill rod 51. To solve this problem, a rubber sleeve 7 is provided. There are two rubber sleeves 7 with the same size. A side opening 71 is provided on the side of the rubber sleeve 7. Before the electric drill 4 starts working, the rubber sleeve 7 is deformed to expand the side opening 71. The side opening 71 can then be fastened to the outer ring of the drill rod 51, above and below the striking block 6. The lower rubber sleeve 7 abuts against the surface of the lower ring block 511, while the upper rubber sleeve 7 abuts against the upper surface of the striking block 6, locking the position of the striking block 6 so that it does not shake during operation.
[0029] When in use, connect the control devices of the electric drill 4 and the electric push rod 21 to power. Before drilling, hold two rubber sleeves 7, one on the outer ring of the drill rod 51 above the lower ring block 511 and the other on the outer ring of the drill rod 51 below the upper ring block 512. The striking block 6 is supported on the surface of the lower rubber sleeve 7, and the upper rubber sleeve 7 abuts against the upper surface of the striking block 6, locking the position of the striking block 6. Then, control the electric drill 4 to rotate the drill rod 51 and drill bit 5, and use the electric push rod 21 to lower the lifting plate 3, allowing the drill rod 51 and drill bit 5 to descend for drilling. If the drill bit 5 gets stuck during drilling, stop the machine. The device is operated by removing the two rubber sleeves 7 to release the lock on the striking block 6. The striking block 6 is then held and moved up and down repeatedly, striking the surfaces of the upper ring block 512 and the lower ring block 511 and transmitting the striking force to the drill bit 5, making it easier to be vibrated and loosened, thus releasing it from its stuck state. If necessary, before striking, the locking of the connector 41 to the drill rod 51 can be released first, so that there is a certain amount of shaking between the top of the drill rod 51 and the connector 41, making it easier to strike and loosen the drill bit 5 from its stuck state. Finally, after locking the connector 41, the striking block 6 is locked again by the two rubber sleeves 7, and then the drilling work continues.
