Description

Technical Field

[0001] The invention relates to the technical field of track maintenance, in particular to a tamping pick with intelligent state monitoring. Background Art

[0002] The lithium-ion battery tamping pick is a small-scale track maintenance machine used for railway trackbed maintenance. It is primarily used for tamping ballast at turnouts and on busy lines during train intervals. It is suitable for tamping ballast and other granular materials, and delivers excellent tamping quality for track lifts greater than 30 mm.

[0003] Traditional lithium-ion tamping picks typically use a fixed eccentric block coupled with motor speed regulation to achieve frequency regulation. However, they suffer from significant shortcomings in amplitude regulation. The amplitude is primarily determined by the fixed parameters of the eccentric block, making it difficult to flexibly and precisely adjust the amplitude based on the specific conditions of the roadbed, such as its material, density, and ballast particle size. In soft areas of the roadbed, excessive amplitude can cause excessive ballast disturbance and damage the roadbed structure. In hard or compacted areas, however, excessive amplitude fails to achieve the desired tamping effect, resulting in inefficient tamping operations and difficulty in ensuring quality.

[0004] At the same time, existing lithium-ion tamping picks lack effective buffering mechanisms, causing vibrations to directly impact the pick and the operator during operation. During high-frequency, high-intensity tamping operations, intense vibrations not only significantly impact the pick's mechanical components, such as the motor and transmission, accelerating component wear, reducing equipment life, and increasing maintenance costs and downtime; they also significantly impact operator comfort and operational stability. Prolonged operation can easily lead to health issues such as hand fatigue, numbness, and even hand-arm vibration syndrome, severely impacting operator motivation and efficiency.

[0005] Therefore, the present invention proposes a tamping pick with intelligent state monitoring to solve the above problems. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a tamping pick with intelligent state monitoring to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tamping pick with intelligent state monitoring, comprising: a tamping pick, wherein two eccentric devices are symmetrically arranged inside the tamping pick, handles are fixedly connected to both sides of the tamping pick, a pick head is installed in the lower middle portion of the tamping pick, a pressure sensor is installed in the pick head, amplitude adjustment mechanisms are provided in both eccentric devices, and a vibration reduction feedback mechanism is provided below the amplitude adjustment mechanism;

[0008] The amplitude adjustment mechanism is used to adjust the vibration frequency to the optimal value according to different roadbed conditions to achieve efficient tamping;

[0009] The vibration damping feedback mechanism is used to reduce the vibration intensity fed back to the handle by the pick head during tamping operation.

[0010] Preferably, the amplitude adjustment mechanism includes a component box, which is fixedly connected to the eccentric device, and a driving device is fixedly connected to the middle of the inner cavity of the component box. Both sides of the driving device are rotatably connected to a cover shell, and a movable cavity is opened in the cover shell. The movable cavity is fixedly connected to a fixed block on the side close to the driving device.

[0011] Preferably, the amplitude adjustment mechanism also includes a driving screw, which is rotatably connected to the middle part of a side of the fixed block away from the driving device, and positioning rods are provided on both sides of the driving screw, and the positioning rods are fixedly connected to the fixed block, and the positioning rod and the end of the driving screw away from the fixed block are fixedly connected to the cover shell, and five eccentric weight blocks are slidably connected to the positioning rod, and the middle part of the eccentric weight block away from the fixed block is rotatably connected to an internal threaded column, and the middle part of the upper surface of the eccentric weight block is rotatably connected to a control rod, and the end of the control rod away from the eccentric weight block is rotatably connected to the fixed block.

[0012] Preferably, the vibration damping feedback mechanism includes a vertical positioning column, which is slidably connected to the inside of the pickaxe head, a shock-absorbing spring is fixedly connected to the middle of the vertical positioning column, a push rod is fixedly connected to the lower surface of the vertical positioning column, and the outer ring of the end of the push rod away from the vertical positioning column is slidably sleeved with a hydraulic cavity, and three flow holes are opened around the center of the circle at the end of the push rod close to the hydraulic cavity, and a current-carrying conductor is fixedly connected to the inner wall of the bottom of the hydraulic cavity.

[0013] Preferably, the driving device can be implemented as a bidirectional driving motor, and the fixed block is an L-shaped block. The fixed block has a built-in driving motor and is electrically connected to an external controller.

[0014] Preferably, the eccentric weight block is a semicircular block, and the internal thread column is threadedly connected to the driving screw.

[0015] Preferably, the vertical positioning column is composed of two cylinders, the hydraulic cavity is provided with electrorheological fluid, and the current-carrying conductor is connected to an external power supply device.

[0016] Compared with the prior art, the present invention provides a tamping pick with intelligent state monitoring, which has the following beneficial effects:

[0017] 1. Through the setting of the amplitude adjustment mechanism, under the tamping contact action of the pick head on the roadbed, according to the differences in roadbed material, density and particle size in different railway sections, the spacing between the eccentric weights is adjusted under the drive of the drive device, so as to adjust the vibration frequency of the tamping pick. On soft roadbed, the spacing is increased and the vibration frequency is increased, and high-frequency and small-amplitude vibration is used to promote rapid rearrangement and compaction of the ballast; on hard roadbed, the spacing is reduced and the vibration frequency is reduced, and low-frequency and large-amplitude vibration is used to provide strong tamping force, break up the compacted layer, and ensure that different roadbeds can achieve the ideal tamping effect. With the help of the driving screw, the operator can quickly adjust the spacing of the eccentric weights during on-site operations, instantly change the vibration frequency, achieve rapid response, and efficiently complete the tamping task.

[0018] 2. By setting up the amplitude adjustment mechanism, the existing technology of adjusting the vibration frequency of the tamping pick by changing the motor speed is avoided. The change of motor speed directly affects the rotation speed of the eccentric weight block, and then changes the vibration frequency. The response speed is slow, and it is difficult to achieve high-precision frequency control during the adjustment process. It is difficult to quickly and accurately reach the target vibration frequency. The present structure changes the vibration frequency by adjusting the spacing of the eccentric weight block itself. This adjustment method does not rely on the change of motor speed, and has relatively low requirements on motor performance and stability. It can also achieve flexible adjustment of the vibration frequency at the optimal operating speed of the motor, so that the motor always runs at the optimal efficiency speed, better avoiding energy waste caused by frequent acceleration and deceleration, and accurately adjusting the vibration frequency according to different roadbed working conditions. It also avoids invalid work caused by too high or too low vibration frequency, thereby reducing the energy consumption of the entire tamping operation process, conforming to the development trend of energy conservation and environmental protection, and reducing the operating cost of railway maintenance.

[0019] 3. Through the setting of the vibration reduction feedback mechanism, when the tamping intensity is high, the pressure sensor is connected to the external control device to control the power supply of the energized conductor, thereby solidifying the electrorheological fluid in the hydraulic chamber and increasing the stiffness. This quickly converts the vibration energy into its own elastic potential energy and internal friction heat energy. When the shock-absorbing spring recovers after contraction, the solidified electrorheological fluid is regarded as a rigid medium, blocking and dispersing the transmission path of high-frequency and large-scale vibrations, reducing the transmission of vibration to the equipment and the operator's hands during tamping work, alleviating vibration hazards, and achieving efficient vibration reduction. The electrorheological fluid state is flexibly adjusted according to the actual amplitude, comprehensively optimizing the performance of the tamping pick under various working conditions, and improving the overall adaptability and work efficiency of the equipment. Furthermore, the electrorheological fluid can effectively suppress large-scale vibrations and prevent unnecessary deviation and shaking of the pick head during vibration. It enables the pick head to always act vertically and accurately on the roadbed ballast, ensuring uniform force and consistent depth each time of tamping. This helps to achieve a tight and uniform arrangement of the roadbed ballast, improve the overall stability and bearing capacity of the roadbed, and ensure the safety and stability of railway operations.

The end of the push rod 33 close to the hydraulic cavity 35 is provided with three flow holes 34 around the center. The bottom inner wall of the hydraulic cavity 35 is fixedly connected to an electric conductor 36. The electric conductor 36 is mainly used for energizing and solidifying when the amplitude is large, and then converting the vibration energy into its own elastic potential energy and internal friction heat energy to achieve a shock absorption effect. The electric conductor 36 is connected to an external power supply device.

[0041] Everything in the above example works as follows:

[0042] The following is the working process of the amplitude adjustment mechanism 2 for adjusting the optimal vibration frequency according to different roadbed conditions to achieve efficient tamping:

[0043] When in use, the tamping pick 1 is started to observe whether its vibration is normal, whether there is any abnormal noise when the motor is running, and whether all components are running smoothly. Then the operator stands at a suitable position outside the track, holds the amplitude adjustment mechanism 2 on both sides of the tamping pick 1 with both hands, and aims the pick head 13 at the trackbed ballast. The tamping pick 1 is started to make it vibrate and act on the ballast. When the pick head 13 is tamping, the tamping vibration intensity is fed back through the pressure sensor in the pick head 13, and then the pressure is fed back to the external controller under the action of the external controller.

[0044] If the tamping intensity is large, the built-in power supply of the fixed block 25 is started to drive the driving screw 27 to rotate forward. When the driving screw 27 rotates forward, the rotation of the driving screw 27 drives the internal threaded column 29 connected to the eccentric block 28 to gradually move toward one end away from the fixed block 25 along the forward rotation direction of the internal threaded column 29, and the movement of the internal threaded column 29 synchronously drives the eccentric block 28 to move in the direction away from the fixed block 25. At the same time, through the connection of multiple control rods 210 between the eccentric blocks 28, when the eccentric blocks 28 on the internal threaded column 29 move, the multiple eccentric blocks 28 are driven at the same time by the connection of the control rod 210 to move horizontally on the positioning rod 26, thereby widening the distance between the multiple eccentric blocks 28, and the distance between the eccentric blocks 28 is expanded. Since the eccentric blocks 28 of the tamping pick 1 will generate centrifugal force when rotating, the centrifugal force is the key factor causing the tamping pick 1 to vibrate and thus achieve the tamping effect. According to the centrifugal force formula F=mω2r, where F is the centrifugal force, m is the mass of the eccentric block, ω is the angular velocity, and r can be understood as the distance from the center of mass of the eccentric block to the center of rotation, which is approximately equivalent to the eccentric block spacing. When the motor speed in the drive device 22, i.e., the angular velocity ω, and the eccentric block mass m are relatively fixed, the larger the eccentric block spacing r, the greater the centrifugal force F. A greater centrifugal force will increase the vibration intensity of the tamping pick 1, thereby generating a greater tamping force and achieving a stronger tamping effect, which corresponds to a greater tamping strength. Based on demand, the interval between the eccentric blocks 28 is adjusted under the drive of the built-in power supply of the fixed block 25 to provide a tamping effect of greater strength. Conversely, the built-in power supply of the fixed block 25 drives the internal threaded column 29 to rotate in the opposite direction, thereby controlling the spacing between the eccentric blocks 28 to decrease and reduce the tamping strength.

[0045] Through the setting of the amplitude adjustment mechanism 2, under the tamping contact action of the pick head 13 on the roadbed, according to the differences in roadbed material, density and particle size of different railway sections, the spacing between the eccentric weights 28 is adjusted under the drive of the driving device 22, so as to adjust the vibration frequency of the tamping pick. On soft roadbed, the spacing is increased to increase the vibration frequency, and high-frequency and small-amplitude vibration is used to promote the rapid rearrangement and compaction of the ballast; on hard roadbed, the spacing is reduced to reduce the vibration frequency, and low-frequency and large-amplitude vibration is used to provide strong tamping force, break up the compacted layer, and ensure that different roadbeds can achieve the ideal tamping effect. With the help of the driving screw 27, the operator can quickly adjust the spacing of the eccentric weights 28 during on-site operations, instantly change the vibration frequency, achieve rapid response, and efficiently complete the tamping task.

[0046] Furthermore, by setting up the amplitude adjustment mechanism 2, the existing technique of adjusting the vibration frequency of the tamping pick by changing the motor speed is avoided. The change in motor speed directly affects the rotation speed of the eccentric weight 28, thereby changing the vibration frequency, resulting in a slow response speed, and it is difficult to achieve high-precision frequency control during the adjustment process, and it is difficult to quickly and accurately reach the target vibration frequency. The present structure changes the vibration frequency by adjusting the spacing of the eccentric weight 28 itself. This adjustment method does not rely on changes in the motor speed, and has relatively low requirements for motor performance and stability. It can also achieve flexible adjustment of the vibration frequency at the optimal operating speed of the motor, so that the motor always runs at the optimal efficiency speed, better avoiding energy waste caused by frequent acceleration and deceleration, and accurately adjusting the vibration frequency according to different roadbed working conditions, and avoiding ineffective work caused by too high or too low a vibration frequency, thereby reducing the energy consumption of the entire tamping operation process, complying with the development trend of energy conservation and environmental protection, and reducing the operating cost of railway maintenance.

[0047] Please refer to the above working process Figures 1 to 6 .

[0048] The following is the working process of the vibration damping feedback mechanism 3 for reducing the vibration intensity fed back from the pick head 13 to the handle 12 during the tamping operation:

[0049] During use, when the pick head 13 is performing tamping work, the vibration force transmitted by the contact between the pick head 13 and the roadbed is transmitted to the shock-absorbing spring 32, causing the shock-absorbing spring 32 to contract. At the same time, the push rod 33 is slidably inserted into the hydraulic cavity 35. Under the action of the circulation hole 34, the electrorheological fluid in the hydraulic cavity 35 circulates in the hydraulic cavity 35. If the tamping intensity is large, it means that the vibration energy is high and the impact force is strong. At this time, the current-carrying conductor 36 is energized to solidify the electrorheological fluid, and its stiffness will be greatly improved. It can quickly convert the vibration energy into its own elastic potential energy and internal friction heat energy. Then, when the shock-absorbing spring 32 is contracted and restored, the solidified electrorheological fluid can be approximately regarded as a rigid medium. It can effectively block and disperse the transmission path of high-frequency and large-scale vibrations, like a solid barrier, making it difficult for vibrations to pass through the hydraulic cavity 35 to other parts of the equipment and the hands of the operator, thereby significantly reducing the vibration hazards and achieving efficient shock absorption.

[0050] On the contrary, even if the amplitude is small, the continuous vibration may interfere with the stable operation of the equipment and the operator's working accuracy. After the electrorheological fluid is energized and solidified, it can still increase the internal damping of the hydraulic cavity 35. This damping effect can consume vibration energy and suppress the accumulation and amplification of small vibrations. At the same time, its certain rigidity after solidification can stabilize the working state of the hydraulic rod, reduce the displacement deviation of components caused by small vibrations, and ensure that the tamping pick 1 can operate smoothly and accurately under small amplitudes, which also has the effect of shock absorption and optimization of working performance.

[0051] Through the setting of the vibration reduction feedback mechanism 3, when the tamping intensity is large, the pressure sensor is connected to the external control device to control the power conductor 36 to be energized, thereby solidifying the electrorheological fluid installed in the hydraulic cavity 35 and improving the rigidity, thereby quickly converting the vibration energy into its own elastic potential energy and internal friction heat energy. When the shock-absorbing spring 32 shrinks and recovers, the solidified electrorheological fluid is regarded as a rigid medium to block and disperse the transmission path of high-frequency and large-scale vibrations, thereby reducing the vibration transmitted to the equipment and the operator's hands during tamping work, reducing the vibration damage, and achieving It can realize efficient shock absorption and flexibly adjust the state of electrorheological fluid according to the actual amplitude, comprehensively optimize the performance of the tamping pick under various working conditions, and improve the overall adaptability and working efficiency of the equipment. Furthermore, the electrorheological fluid can effectively suppress large vibrations in vibration reduction, prevent unnecessary deviation and shaking of the pick head 13 during the vibration process, and enable the pick head 13 to always act vertically and accurately on the roadbed ballast, ensuring uniform tamping force and consistent depth each time, which is conducive to achieving a tight and uniform arrangement of the roadbed ballast, improving the overall stability and carrying capacity of the roadbed, and ensuring the safety and stability of railway operation.
