Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mechanical engineering, and more particularly to an anti-axial vibration device. Background Art
[0002] Anti-axial vibrator is a device specially designed to resist or reduce the influence of axial vibration. It is widely used in mechanical systems that require stable operation, such as drilling tools, industrial screening equipment, precision machining machine tools, etc. It uses elastic support or damping materials to absorb axial vibration energy and reduce vibration transmission. It optimizes structural stiffness to avoid the occurrence of resonance. It integrates sensors and controllers to monitor axial vibration in real time, and adjusts equipment operating parameters through feedback system to suppress vibration.
[0003] Traditional anti-vibration devices use a single hydraulic cylinder structure, such as a cylinder damper. When encountering a hard object during drilling, the instantaneous impact energy far exceeds the cylinder pressure relief threshold, and the hydraulic oil temperature rises sharply, causing the sealing ring to carbonize and fail. The hydraulic cylinder is also pressurized and deformed. Most products will leak under impact conditions, and the single energy path will cause the system to overheat and some structures to fail.
[0004] Traditional anti-vibration devices use a simple four-bar linkage mechanism, but the displacement accuracy of the purely articulated link is easily out of control. Without a pulley limiter, the cumulative error of the articulated gap becomes larger, and the tilt angle deviation of the jacking platform will become larger. In addition, the traditional link has no horizontal constraint. When lateral force is generated to induce the mechanism to swing and twist, the structure will break. Summary of the Invention

[0007] Furthermore, when the device senses vibration, the circular shaft will start the connected rotating motor, drive the hydraulic pump mechanism to start moving, and drive the hydraulic oil to circulate inside the hydraulic pump mechanism and the first-level hydraulic cylinder mechanism. The first-level hydraulic cylinder mechanism and the second-level hydraulic cylinder mechanism will move in the vertical direction, and continue to serve as new power to push the sliding push rod mechanism to move. The same lever is used to stretch the sliding rod mechanism, push the top shell upward, and contact and squeeze the vibrating structure to suppress the vibration.
[0008] Furthermore, the first-level hydraulic cylinder mechanism includes a first-level outer cylinder, chassis one and a lower hydraulic port; the second-level hydraulic cylinder mechanism includes a second-level outer cylinder, chassis three, chassis two and an upper hydraulic port; the bottom of the third-level hydraulic cylinder is fixedly connected to chassis three; a second-level outer cylinder is provided on the outer side of the bottom of the third-level hydraulic cylinder; the bottom of the second-level outer cylinder is fixedly connected to chassis two; a first-level outer cylinder is provided on the outer side of the bottom of the second-level outer cylinder; the bottom of the first-level outer cylinder is fixedly connected to chassis one.
[0009] Furthermore, when the three-stage hydraulic cylinder moves upward, the straight cylinder rod and the circular fixed shaft connected thereto will also move upward. Under the restriction of the circular fixed shaft and the T-shaped frame, the limit rod 2 will move synchronously in the vertical and horizontal directions. During its movement, the pulley 2 fixedly connected to the bottom of the T-shaped frame will move along the fixed rod. The limit rod 2 and the lower fixed seat are fixedly connected to the connecting rod 1. The upper pulley 1 on the other side and the lower fixed seat are fixedly connected to the connecting rod 2. The connecting rod 2 and the connecting rod 1 are fixedly connected by the limit rod 1. When the first-stage hydraulic cylinder moves downward, the limit rod 2 also moves synchronously downward and toward the side away from the lower fixed seat under the restriction of the hydraulic moving mechanism, while driving the connecting rod 1 to rotate clockwise around the lower fixed seat, and the connecting rod 1 will rotate counterclockwise around the upper pulley 1. Conversely, when the third-stage hydraulic cylinder moves upward, the limit rod 2 will drive the connecting rod 1 to rotate counterclockwise around the lower fixed seat, and the connecting rod 1 will rotate clockwise around the upper pulley 1. The connecting rod 1 and the connecting rod 2 move together to drive the top shell to move upward or downward in the vertical direction, thereby suppressing the vibration of the structure.

[0012] Furthermore, when the hydraulic oil moves from the lower hydraulic port into the first-level outer cylinder, it will push the second-level outer cylinder and the third-level hydraulic cylinder to move upward. When the hydraulic oil enters the second-level outer cylinder from the upper hydraulic port, it will compress and push the third-level hydraulic cylinder and the second-level outer cylinder to retract in turn.
[0013] Furthermore, the fixed column is fixedly connected to an outer disk on one side close to the first-stage outer cylinder, the circular shaft is fixedly connected to a central rotating shaft on one side close to the first-stage outer cylinder, the outer disk is fixedly connected to outlet two on one side close to hydraulic pipe two, and the other side of the outer disk is fixedly connected to outlet one, an inner disk is provided on the side of the central rotating shaft close to the outer disk, and a rocker rod two is rotatably connected to the side of the central rotating shaft close to the inner disk, and a rocker rod one is provided on the other side of the rocker rod two.
[0014] Furthermore, after the circular shaft drives the motor, the central shaft will rotate, causing the rocker arm 2 and the rocker arm 1 on it to rotate internally. During the rotation of the eccentric setting of the inner disk, the hydraulic oil flows inside the pores of the outer disk and the inner disk. The rocker arm 2 and the rocker arm 1 stir the hydraulic oil to move, and the oil flows inside the lower hydraulic port, hydraulic pipe 1, hydraulic pump mechanism, hydraulic pipe 2 and upper hydraulic port of the circuit.
[0015] The technical effects and advantages of the present invention are as follows:
[0016] The present invention is provided with a first-level hydraulic cylinder mechanism and a three-level telescopic hydraulic cylinder for gradient energy consumption. The first-level hydraulic cylinder: when high-pressure oil is injected into the lower hydraulic port at the bottom of the chassis, the first-level outer cylinder is pushed upward to consume a small part of the low-frequency impact energy. The second-level hydraulic cylinder: the hydraulic oil enters the second-level outer cylinder through the hydraulic oil channel, pushing the chassis two and the third-level hydraulic cylinder to rise in conjunction, absorbing most of the medium-frequency vibration; the third-level hydraulic cylinder: the straight cylinder rod drives the hydraulic moving mechanism to make vertical fine adjustments, and finely resolves the remaining high-frequency residual vibrations. The durability and tolerance of the three-level hydraulic pressure in the face of large-scale impact conditions are higher, and the internal hydraulic oil is not easy to heat up and affect the structure.
[0017] The present invention is provided with a sliding push rod mechanism. When the hydraulic cylinder rises, the limit rod 2 drives the connecting rod 1 to rotate counterclockwise around the lower fixed seat, and at the same time, the connecting rod 2 rotates clockwise around the upper pulley 1, forming four groups of symmetrical upward thrusts; when the hydraulic cylinder descends, the reverse motion synchronously compresses the vibration space. The presence of the pulley reduces the problem of structural torsional fracture caused by partial lateral force in the traditional structure, and solves the problem of instantaneous accumulation of axial vibration energy caused by sudden encounter with hard and difficult-to-breakthrough objects during drilling.
