Technical Field

[0001] The utility model relates to the technical field of drill barrel driving, in particular to a vibration core pushing device. Background Art

[0002] Tunnel core drilling rigs are devices specifically used for collecting rock or concrete core samples during tunnel construction, maintenance, and geological exploration. Such drilling rigs are mainly used to detect the quality of tunnel linings, evaluate the strength of rocks or concrete, and other geological properties.

[0003] The prior art (publication number: CN221346782U) discloses a driving device for a tunnel drill barrel, including a main gearbox, an air intake cover, a water intake cover, a secondary gearbox, a main shaft flange, a drill barrel, a guide member, a drill rig, a hexagonal shaft, a bipolar oil cylinder group, a slipper assembly, a motor, a driving gear, a transition gear, a driven gear, a drill barrel driving gear, and a drill barrel driven gear; the main gearbox uses a dual motor. After power transmission through the transition gear and the driven gear, it effectively improves the torque during the operation of the drill barrel, ensures the power during the operation of the drill barrel, improves the drilling efficiency. Through the ingenious design of the installation structure of the hexagonal shaft and the drill barrel driving gear, the drill barrel can still be telescoped when the main gearbox is fixed, reducing the load of the drill barrel and improving the stability of the drill barrel. Compared with the traditional power mechanism that follows the movement of the drill barrel, the length of the pipeline is shortened, and the pipeline does not need to follow the movement of the drill barrel. The device structure is ingenious and is conducive to popularization and use.

[0004] When the drill barrel of the prior art works on different rock formations, the drill barrel needs to be retracted to discharge the rocks in the drill barrel. However, during the retraction process, it is easy to encounter the working condition of rock core jamming. At this time, the staff needs to manually knock the drill barrel to shake the internal rocks and discharge the rocks in the drill barrel, which seriously affects the working efficiency of the tunnel core drilling rig. Therefore, we propose a vibration core pushing device to solve the above problems. Content of the Utility Model

[0005] The utility model aims to provide a vibration core pushing device to solve the problem that the drill barrel is prone to rock core jamming when retracting.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a vibration core pushing device, including a drill rig, an installation seat is provided at the upper end of the drill rig, a driving member is provided on the installation seat, a vibration shaft is provided at the output end of the driving member, an eccentric block is provided on the outer wall of the end of the vibration shaft far from the driving member, a vibration sleeve is provided on the outer wall of the end of the vibration shaft close to the eccentric block, and the vibration sleeve is located inside the drill barrel.

[0007] The beneficial effects of this solution are as follows: The driving part drives the vibration shaft to rotate. Since an eccentric block is provided at the end of the vibration shaft, the vibration shaft vibrates under the action of the eccentric block, thereby driving the vibration sleeve to vibrate, and then loosening the rock stuck in the drill barrel, preventing the core from getting stuck when the drill barrel retracts, and increasing the working efficiency of the tunnel drill.

[0008] Preferably, as an improvement, a bushing is provided at one end of the mounting seat away from the driving part, and the bushing is sleeved on the outer wall of the vibration shaft. One end of the bushing away from the driving part is connected to the vibration sleeve.

[0009] The beneficial effects are as follows: One end of the bushing is connected to the mounting seat, and the other end is connected to the vibration sleeve, thereby fixing the vibration sleeve. When the driving part drives the vibration shaft to rotate, the vibration sleeve does not rotate with the vibration shaft, thereby reducing the wear on the inner wall of the drill barrel and increasing the service life of the drill barrel.

[0010] Preferably, as an improvement, a bearing seat is provided at the upper end of the drill rig. The mounting seat is arranged at one end of the bearing seat, and the bushing penetrates through the bearing seat.

[0011] The beneficial effects are as follows: The bearing seat is used to fix the mounting seat, further improving the stability of the driving part during operation. At the same time, the bearing in the bearing seat can also dampen the vibration of the bushing, reducing the vibration amplitude of the bushing and avoiding wear on the inner wall of the drill barrel.

[0012] Preferably, as an improvement, a wear-resistant plate is provided at one end of the vibration sleeve away from the driving part.

[0013] The beneficial effects are as follows: The wear-resistant plate is used to protect the vibration sleeve, the vibration shaft and the eccentric block located inside the vibration sleeve, preventing rocks from entering the vibration sleeve and causing damage to internal components.

[0014] Preferably, as an improvement, the drill barrel is provided with water holes running through it.

[0015] The beneficial effects are as follows: By introducing water from one end of the gearbox and discharging it from the front end of the drill barrel, it can effectively reduce the dust generated during the operation of the drill barrel and also reduce the noise generated during the operation of the drill barrel.

[0016] Preferably, as an improvement, air holes are provided running through the bearing seat, the bushing, the vibration sleeve and the wear-resistant plate. One end of the air hole is opened at one end of the bearing seat close to the driving part, and the other end penetrates through the wear-resistant plate.

[0017] The beneficial effects are as follows: High-pressure gas is introduced from one end of the bearing seat and reaches the front end of the wear-resistant plate through the air hole, thereby blowing out the fine rocks in the drill barrel and preventing the fine rocks from entering the inside of the large drill barrel.

[0018] Preferably, as an improvement, bearings are provided on both the front and rear inner walls of the vibration sleeve, and the vibration shaft is rotatably installed between the two bearings.

[0019] The beneficial effects are as follows: The bearing can improve the smoothness of the rotation of the vibrating shaft. At the same time, due to the relatively long vibrating shaft, the bearing can provide certain support for the vibrating shaft, thereby increasing the stability of the vibrating shaft during rotation.

[0020] Preferably, as an improvement, the driving member is set as a motor.

[0021] The beneficial effects are as follows: The motor can achieve high-speed operation and maintain high-speed stability during operation, thereby improving production efficiency and product quality. Description of the Drawings

The rotating shaft is rotatably installed inside the gearbox. A drill barrel 4 is fixedly installed at the right end of the rotating shaft. For the specific structure, please refer to the prior art (publication number: CN221346782U), and no further elaboration will be made here. A bearing seat 11 is fixedly installed on the left side of the upper end of the drill rig 1, as shown in Figure 3The lower end of the bearing seat 11 shown is fixed with a mounting seat 6 by bolts, and a driving member 7 is detachably fixedly installed on the lower end of the mounting seat 6. The driving member 7 is set as a motor, and a vibration shaft 5 is fixedly installed on the output end of the driving member 7, and the upper end of the vibration shaft 5 rotates through the bearing seat 11, the tooth box and the drill tube 4 in sequence. A shaft sleeve 10 is fixedly installed on the upper end of the mounting seat 6, and the shaft sleeve 10 is fixedly sleeved on the outer wall of the vibration shaft 5. A vibration sleeve 9 is fixedly installed on the upper end of the shaft sleeve 10 through a flange, and the vibration sleeve 9 covers the upper end of the vibration shaft 5, and the vibration shaft 5 can rotate in the vibration sleeve 9. An eccentric block 8 is fixedly installed on the outer wall of one end of the vibration shaft 5 located at the vibration sleeve 9, and a wear-resistant plate 12 is fixedly installed on the upper end of the vibration sleeve 9. Bearings 13 are fixedly installed on the upper and lower inner walls of the vibration sleeve 9, and the vibration shaft 5 is connected to the two bearings 13.
