Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a vibration-damping device and method for geological exploration drilling equipment. Background Technology

[0002] In geological exploration, drilling equipment is the core equipment for obtaining underground geological information, and its drilling accuracy directly affects the accuracy and reliability of geological exploration data. However, during drilling operations, due to the complex underground rock structure (such as the presence of hard rock layers, fracture zones, etc.), the drill bit will generate severe vibrations when it comes into contact with the rock layer. This vibration will not only be transmitted to the main structure of the drilling equipment, but will also cause the drill rod to deviate, thus causing the drilling position to deviate from the preset exploration trajectory. Summary of the Invention

[0003] The purpose of this invention is to provide a vibration-damping device and method for geological exploration drilling equipment. Through a linkage design, the clamping plate and clamping rod achieve synchronous clamping action. A unidirectional lead screw drives the first slider to move the clamping plate horizontally. Simultaneously, through the transmission cooperation of bevel gears, sprockets, and chains, the clamping rod moves synchronously towards the drill rod, forming a multi-directional, coordinated clamping and positioning effect, ensuring the firmness and coaxiality of the drill rod clamping. The fixed base, with the cooperation of the support plate and fixing nails, achieves a stable connection with the working face, providing a reliable installation foundation for the entire device and preventing overall displacement caused by base loosening during the initial stage of operation. The combination structure of the second sliding frame, guide rod, and buffer spring in the vertical limiting mechanism not only strictly limits the horizontal displacement of the moving seat but also absorbs the vertical vibration generated during drilling through the elastic buffering effect of the buffer spring, significantly reducing the impact of vibration on the device's positioning accuracy. The dustproof sleeve also extends the service life of the guide rod, ensuring the long-term stable operation of the limiting mechanism.

[0004] To achieve the above objectives, the present invention provides a vibration-damping device for geological exploration drilling equipment, comprising a fixed base and a movable base. A vertical limiting mechanism is provided between the fixed base and the movable base. A support plate is connected to the side wall of the fixed base, and a fixing nail is provided on the support plate. A first sliding frame is provided on both the fixed base and the movable base. A first slider is provided inside the first sliding frame. An adjustment mechanism is provided between the first sliding frame and the first slider. A connecting rod is provided on the side wall of the first slider. The other end of the connecting rod passes through the first sliding frame and is connected to a clamping plate. A linkage mechanism is provided inside both the fixed base and the movable base. The adjustment mechanism is connected to the linkage mechanism. A first sprocket is provided inside both the fixed base and the movable base. The first sprocket is connected to the linkage mechanism. A rotating shaft is provided on the first sprocket. A clamping rod is provided on the rotating shaft. A fixed shaft is provided inside both the fixed base and the movable base. The other end of the clamping rod is provided on the fixed shaft.

[0005] Preferably, the adjusting mechanism includes a one-way lead screw, which is disposed inside the first slide frame, and a first slider is disposed on the one-way lead screw and slides along the first slide frame via the one-way lead screw.

[0006] Preferably, a groove is provided inside the first sliding frame, and a rotating rod is provided inside the groove. One end of the rotating rod is connected to a one-way lead screw. A first bevel gear is provided on the rotating rod, and a second bevel gear meshes with one side of the first bevel gear. The second bevel gear is connected to a linkage mechanism. One end of a rotating rod passes through the side wall of the first sliding frame and is connected to a servo motor.

[0007] Preferably, the linkage mechanism includes a second sprocket, a connecting shaft connected to the bottom surface of the second bevel gear, the second sprocket being mounted on the connecting shaft, a chain being sleeved between the second sprockets, the chain meshing with the second sprockets, and the first sprocket meshing with the chain.

[0008] Preferably, the top surface of the first sprocket is provided with a connecting seat, and both the fixed base and the movable base are provided with annular grooves. The connecting seat is inserted into the annular groove and slides along the annular groove.

[0009] Preferably, the vertical limiting mechanism includes a second sliding frame, which is disposed on the side wall of the fixed base, and a second slider is disposed on the second sliding frame, the side wall of the second slider being connected to the movable seat.

[0010] Preferably, a guide rod is provided inside the second sliding frame, the second slider is disposed on the guide rod and slides vertically along the guide rod, and a buffer spring is sleeved on the guide rod, one end of the buffer spring is in contact with the second slider, and the other end of the buffer spring is in contact with the inner wall of the second sliding frame.

[0011] Preferably, a dustproof sleeve is fitted on the guide rod, with one end of the dustproof sleeve connected to the second slider and the other end of the dustproof sleeve connected to the inner wall of the second slide frame.

[0012] Preferably, both the clamping plate and the clamping rod are equipped with ball bearings to assist the rotation of the drill rod.

[0013] A method for using a vibration damping device for geological exploration drilling equipment includes the following steps:

[0014] S1: Place the fixed base at the designated location for geological exploration drilling operations, and drive the fixing nails on the support plate into the soil layer of the working face to achieve a stable connection between the fixed base and the working face, ensuring that the overall deployment of the device is flat;

[0015] S2: Pass the drill rod through the clamping areas corresponding to the fixed base and the movable seat in sequence, start the servo motor, the servo motor drives the output shaft to rotate, the output shaft rotates the rod, the rotating rod drives the one-way screw to rotate, so that the first slider slides horizontally along the first slide frame through the one-way screw, and then pushes the clamping plate closer to the drill rod through the connecting rod. At the same time, the meshing transmission of the first bevel gear and the second bevel gear drives the connecting shaft to rotate, and then drives the second sprocket to rotate. The chain realizes the synchronous linkage of multiple second sprockets, and the chain drives the first sprocket to rotate, so that the clamping rod swings synchronously towards the drill rod through the rotating shaft and the fixed shaft until the clamping plate and the clamping rod clamp the drill rod together. At this time, the rotating balls on the clamping plate and the clamping rod are in contact with the surface of the drill rod.

[0016] S3: Drilling operation is carried out. The drilling equipment is started to drive the drill rod to rotate. During the rotation of the drill rod, the ball bearings on the clamping plate and clamping rod roll synchronously with the drill rod, which reduces the rotation resistance of the drill rod and ensures the clamping and positioning accuracy. During the operation, the second slider slides vertically along the second slide frame through the guide rod, which limits the horizontal displacement of the moving seat and prevents the overall device from deviating.

[0017] S4: After drilling is completed, shut down the drilling equipment and start the servo motor. The servo motor drives the output shaft to rotate in the reverse direction. The output shaft rotates the rod, which drives the one-way screw to rotate. This causes the first slider to slide horizontally along the first slide frame via the one-way screw. Then, the connecting rod pulls the clamping plate away from the drill rod. At the same time, the meshing transmission between the first and second bevel gears drives the connecting shaft to rotate, which in turn drives the second sprocket to rotate. The chain enables the synchronous linkage of multiple second sprockets. The chain also drives the first sprocket to rotate, causing the clamping rod to move away from the drill rod synchronously via the rotating shaft and the fixed shaft, until the clamping plate and clamping rod are simultaneously disengaged from the drill rod. After the drill rod is removed, the second slider slides vertically along the second slide frame via the guide rod through the action of the buffer spring, which in turn drives the moving seat to return to the initial position.

[0018] S5: Remove the fixing nails on the support plate and move the entire device away from the work surface.

[0019] Therefore, this invention employs the aforementioned anti-vibration deviation device and method for geological exploration drilling equipment. Through a linkage design, it achieves synchronous clamping action between the clamping plate and the clamping rod. A unidirectional lead screw drives the first slider to move the clamping plate horizontally. Simultaneously, through the transmission cooperation of bevel gears, sprockets, and chains, the clamping rod is driven to move synchronously towards the drill rod, forming a multi-directional and coordinated clamping and positioning effect, ensuring the firmness and coaxiality of the drill rod clamping. Through the fixed base, with the cooperation of the support plate and fixing nails, a stable connection with the working face can be achieved, providing a reliable installation foundation for the entire device and avoiding overall deviation caused by loosening of the base in the early stages of operation. Through the combination structure of the second sliding frame, guide rod, and buffer spring in the vertical limiting mechanism, the horizontal displacement of the moving seat can be strictly limited, and the vertical vibration generated during drilling can be absorbed through the elastic buffering effect of the buffer spring, greatly reducing the impact of vibration on the positioning accuracy of the device. The dustproof sleeve can also extend the service life of the guide rod and ensure the long-term stable operation of the limiting mechanism.

[0039] A method for using a vibration damping device for geological exploration drilling equipment includes the following steps:

[0040] S1: Place the fixed base 1 at the designated location for geological exploration drilling operations, and drive the fixing nails 4 on the support plate 3 into the soil layer of the working face to achieve a stable connection between the fixed base 1 and the working face, ensuring that the overall deployment of the device is flat.

[0041] S2: Pass the drill rod through the clamping areas corresponding to the fixed base 1 and the movable base 2 in sequence, start the servo motor 18, the servo motor 18 drives the output shaft to rotate, the output shaft rotating rod 15 rotates, the rotating rod 15 drives the one-way screw 13 to rotate, so that the first slider 6 slides horizontally along the first slide frame 5 through the one-way screw 13, and then pushes the clamping plate 8 to move closer to the drill rod through the connecting rod 7.

Then, through the connecting rod 7, the clamping plate 8 is pulled away from the drill rod. At the same time, through the meshing transmission of the first bevel gear 16 and the second bevel gear 17, the connecting shaft 20 is driven to rotate, which in turn drives the second sprocket 19 to rotate.
