Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and more specifically to a turnout tamping machine. Background Technology

[0002] The stable operation of railway tracks depends on the load-bearing capacity of sleepers and ballast. However, during long-term operation, sleepers and ballast will suffer daily wear and tear due to factors such as train rolling and environmental erosion. If not maintained in time, this can easily lead to track settlement and reduced smoothness, affecting the smoothness and safety of transportation.

[0003] After replacing railway sleepers, the ballast underneath must be tamped to improve track stability by increasing its density. Currently, tamping methods in the industry mainly fall into two categories: one is large tamping machines, which offer high tamping efficiency but are bulky, inconvenient to move, and limited by railway schedules, making them unsuitable for routine small-scale maintenance work, especially in complex areas such as turnouts; the other is manual tamping, which involves manually striking the ballast with simple tools. This method is not only extremely labor-intensive and inefficient, but also results in inconsistent tamping density and poor work quality due to uneven manual control. Utility Model Content

[0004] One advantage of this invention is that it provides a turnout tamping machine. By adding a lifting leg cylinder, it achieves the lifting leg avoidance function of the tamping pick on one side, solving the industry pain point that ordinary tamping machines cannot insert the tamping leg on one side of the turnout position. It can achieve full coverage operation in the turnout area and conventional lines without manual tamping. Relying on an excavator as the power carrier, and with the precise control of each action by hydraulic valves, it improves the work efficiency. The stable vibration of the eccentric shaft, combined with the balance design of the counterweight plate, improves the uniformity of the compaction of the ballast at the bottom of the sleeper, and the work quality is far superior to that of manual labor and simple equipment. The composite structure of the shock-absorbing pad effectively absorbs vibration energy, improves the fatigue life of the key structure of the equipment, and reduces vibration damage to the excavator. The protective design of the counterweight plate shell and rubber pads avoids injury from rotating parts and rail wear, respectively, significantly improving the safety factor of operation. There is no need to design a separate power system; it can be operated using existing excavators. The structure is simple, the vulnerable parts are easy to replace, and the maintenance cost is low, making it suitable for widespread application.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0019] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0020] After the railway ballast is laid, it needs to be tamped to increase its density. A tamping machine can be used to vibrate and tamp the ballast under the sleepers on both sides of the rail to increase its density. Ordinary tamping machines can be used on normal tracks, but at railway turnouts, due to railway restrictions, the tamping leg on one side may not be able to be inserted, so ordinary tamping machines cannot complete the work. This turnout tamping machine can raise the tamping leg on one side of the railway turnout by extending and retracting the hydraulic cylinder, so that the tamping leg on one side can be inserted for work.

[0021] A turnout tamping machine includes an upper support assembly, a slewing assembly, a shock absorption assembly, a lower support assembly, a tamping power assembly, a tamping execution assembly, and a leg-lifting adjustment assembly. The components are connected in sequence to form a complete working unit, which can be adapted to an excavator as a power carrier to achieve flexible operation.

[0022] The upper support assembly serves as the connection base between the equipment and the power carrier. It includes an upper support ear plate 2 and a hydraulic valve 1. The upper support ear plate 2 is fixed to the top of the upper support body and is used for detachable connection with the front end of the excavator boom. According to conventional settings, it can be connected by a pin hinge for easy quick assembly and disassembly. The hydraulic valve 1 is installed on the side of the upper support body and can adopt an electromagnetic directional valve structure. It is used to control the oil circuit opening and closing and pressure regulation of all cylinders and hydraulic components of the equipment, so as to achieve precise control of each action.

[0023] The slewing assembly enables flexible adjustment of the equipment's operating angle, including a slewing motor 3, a center connector 13, and a grease fitting 12 for the slewing motor. The slewing motor 3 is fixed to the bottom of the upper support body, and its output end is connected to the lower support 6 assembly for transmission. It is used to control the rotation angle and position of the lower support 6, enabling continuous rotation from 0 to 360° to adapt to different operating orientation requirements. The center connector 13 is integrated inside the slewing motor 3 and adopts a multi-pass rotary sealing structure. It is responsible for controlling the smooth flow of each hydraulic line and preventing cross-entanglement during equipment rotation, ensuring continuous oil supply during 360° rotation. The grease fitting 12 for the slewing motor is located on the side of the slewing motor 3 housing, extends to the upper support through an oil pipe, and is equipped with a grease nipple for periodically lubricating the internal transmission structure of the slewing motor 3 with grease.

[0024] The vibration damping assembly is used to reduce the impact of tamping vibration on the carrier and the equipment itself. It includes an upper damping pad 4, a lower damping pad, and four damping pads 5. The upper surface of the upper damping pad 4 is fixedly connected to the heightening ring of the slewing assembly. The heightening ring is used to increase the height and avoid obstacles, preventing it from touching the lower bolts during rotation. The lower surface is fixed to the damping pads 5. It is made of stamped steel plate and has four sets of bolt holes on the surface. Each set of bolt holes includes four fixing bolt holes and one auxiliary positioning hole. It is connected to the damping pads 5 through bolt holes. The damping pads 5 can be spring structures or nitrile rubber composite structures, etc., which can generate damping energy dissipation and vibration reduction effects. They have excellent vibration damping and buffering performance. During tamping operations, they can absorb vibration energy, reduce the transmission of vibration to the upper support assembly and excavator, and improve operational stability and equipment life.

[0025] The lower support 6 is the core load-bearing and connecting component of the equipment. It adopts a welded steel structure and is made of side plates, vertical plates and tie plate. The whole structure is a symmetrical frame structure. The two sides are provided with disc connection holes for installing the tamping power component, and the middle is provided with pin hole for connecting the tamping execution component, ensuring the structural strength of the connection of each component.

[0026] The tamping power assembly provides vibration power for tamping operations and includes a hydraulic motor 15, a spline sleeve 16, an eccentric shaft 18, a bearing assembly, and a counterweight unit. The hydraulic motor 15 is fixed to the disc connection hole on one side of the lower support 6 to provide power for the overall tamping.

[0027] Spline sleeve 16 is installed between the spline shaft of hydraulic motor 15 and the spline of eccentric shaft 18. It is forged from alloy steel and has an involute spline in the inner hole to achieve a rigid connection between the motor spline and the spline of eccentric shaft 18, so that the power of hydraulic motor 15 can be continuously and smoothly transmitted to eccentric shaft 18. Eccentric shaft 18 horizontally passes through the disc connection holes on both sides of the lower bracket 6 and is connected to hydraulic motor 15 for transmission. It generates periodic excitation force through its own eccentric rotation, which drives the tamping actuator to achieve vibration tamping. The bearing assembly includes a motor end bearing 17, a counterweight side bearing 19, and a counterweight side thrust bearing 20. The motor end bearing 17 is mounted on the side of the eccentric shaft 18 closest to the hydraulic motor 15. The counterweight side bearing 19 and the counterweight side thrust bearing 20 are mounted on the side of the eccentric shaft 18 closest to the counterweight unit, ensuring the stability of the eccentric shaft 18 during high-speed rotation. The motor side plate and the eccentric shaft 18 are connected to the disc connecting hole. The spline sleeve 16 and the motor end bearing 17 are located inside the motor side plate. The motor side plate is connected to a motor side plate yellow... The grease port on the motor side plate extends through an oil pipe to the lower bracket 6 and is equipped with an oil nozzle, which is fixedly installed on the lower bracket 6. The counterweight side bearing 19 and the counterweight side thrust bearing 20 are located inside the eccentric shaft 18 structural plate. The eccentric shaft 18 structural plate is connected to the eccentric shaft structural plate grease port 14. The eccentric shaft structural plate grease port 14 extends through an oil pipe to the lower bracket 6 and is equipped with an oil nozzle, which is fixedly installed on the lower bracket 6. This can improve stability and lubricate the structure with lubricating oil, thereby increasing the service life of the structure.

[0028] Furthermore, the specific structural form of the eccentric shaft 18 and bearing assembly is as follows: A disc on the outer side of the spline sleeve 16 supports the motor, and a disc on the inner side of the spline sleeve 16 supports the inner ring of the motor end bearing 17. The bearing is located inside the spline of the eccentric shaft 18, with a grease seal on the inner side of the bearing. Further inward is the lug plate of the opening / closing cylinder 7. Between the lug plate of the opening / closing cylinder 7 and the eccentric shaft 18, there is also a bearing and a seal. After the lug plate of the opening / closing cylinder 7 is an oil seal, after which is a bearing, after which is a top ring, and after the top ring is a thrust bearing. The outer side of the thrust bearing is an oil seal, and further out is a tapered counterweight disc. The inner side of the counterweight disc has a grease port for adding grease.

[0029] The counterweight unit includes a counterweight disc 23, counterweight fixing bolts 21 and washers, and a counterweight disc housing 22. The counterweight disc 23 is fixed to the end of the eccentric shaft 18 by the counterweight fixing bolts 21 and washers to balance the centrifugal force generated by the rotation of the eccentric shaft 18 and improve vibration stability. The counterweight fixing bolts 21 and washers are made of high-strength bolts and spring washers to prevent the counterweight disc 23 from loosening and falling off during high-speed rotation. The counterweight disc housing 22 is made of thin steel plate welded and is placed on the outside of the counterweight disc 23 to prevent personnel from being injured or debris from being caught in the counterweight disc 23 during rotation, thereby improving operational safety. The eccentric shaft 18 works with the hydraulic motor 15 to perform tamping, and its eccentricity can be designed according to the tamping density requirements.

[0030] The tamping actuator directly realizes the ballast tamping operation, including an opening and closing cylinder 7, a tamping pick bracket 8, a tamping pick 11, and a rubber pad 10; the outer end of the opening and closing cylinder 7 is hinged to the top of the tamping pick bracket 8, and the inner end is hinged to the eccentric shaft 18, which is responsible for transmitting the vibration power generated by the eccentric shaft 18 to the tamping pick 11 and controlling the opening and closing angle of the tamping pick 11 to adapt to different sleeper spacings; the tamping pick bracket 8 adopts a cast steel structure, with the middle part hinged to the lower bracket 6 through a pin shaft, and the top connected to the opening and closing cylinder 7, which is used to install and fix the tamping pick 11 and transmit vibration and opening and closing power; The tamping pick support 8 includes a fixed tamping pick seat and a deflecting tamping pick seat. The fixed tamping pick seat is located on one side of the lower end of the tamping pick support 8, and the deflecting tamping pick seat is hinged to the other side of the lower end of the tamping pick support 8. One end of the lifting leg cylinder 9 is hinged to the top of the tamping pick bracket 8, and the other end is hinged to the deflection tamping pick seat. Its extension and retraction are controlled by the hydraulic valve 1. When working on a turnout section, if the tamping leg on one side is blocked by the turnout structure and cannot be inserted, the lifting leg cylinder 9 can be controlled to retract, causing the tamping pick bracket 8 on that side to flip upward, avoid the turnout obstacle, and then extend to insert into the ballast layer for operation, thus achieving flexible adaptation to turnout sections.

[0031] The tamping pick 11 is forged from high manganese steel. Its head is wedge-shaped to facilitate insertion into the ballast layer. The tamping pick 11 is connected to the fixed tamping pick seat and the deflection tamping pick seat by two bolts on the side and one bolt on the top, which facilitates replacement after wear. During operation, it is inserted into the ballast layer and compacted by vibration.

[0032] The rubber pad 10 is made of wear-resistant rubber and is fixed in the middle of the tamping pick bracket 8 on the side close to the rail. It is located between the fixed tamping pick seat and the deflecting tamping pick seat. It is used to fit against the side of the rail during operation to prevent the equipment from causing wear on the rail surface during operation, and at the same time further reduce impact vibration.

[0033] The equipment assembly process includes: Basic assembly: Weld the upper bracket ear plate 2 to the top of the upper bracket body, fix the hydraulic valve 1 to the side of the upper bracket with bolts, and connect the excavator hydraulic system pipeline; hoist and fix the swing motor 3 to the bottom of the upper bracket, pre-install the center connector 13 inside the swing motor 3, ensure that the oil circuit interface is connected to the hydraulic valve 1 pipeline, and install the grease nipple of the swing motor grease port 12.

[0034] Assembly of the shock absorber and the lower support 6: Install the shock absorber 5 between the upper seat plate 4 and the lower seat plate of the shock absorber, and fix the upper seat plate 4 of the shock absorber to the heightening ring of the rotating assembly with bolts; fix the lower support 6 (with the side plate, upright plate and reinforcing plate pre-welded) to the lower surface of the lower seat plate of the shock absorber with bolts to ensure that the connection surface is flat and without gaps.

[0035] Power component assembly: The motor end bearing 17 is press-fitted onto one end of the eccentric shaft 18 via the motor side plate, and then inserted through the disc connection hole on one side of the lower bracket 6. During the insertion process, it needs to pass through the ear plates on the ends of the two opening and closing hydraulic cylinders 7 in one go. The other end is press-fitted onto the counterweight side bearing 19 and the counterweight side thrust bearing 20 in sequence via the eccentric shaft 18 structural plate. The hydraulic motor 15 is fixed to the side of the lower bracket 6 via the flange, so that the spline shaft of the motor is aligned with the spline of the eccentric shaft 18, and the spline sleeve 16 is inserted to achieve a rigid connection. The counterweight plate 23 is inserted into the end of the eccentric shaft 18 and locked with the gasket by the counterweight fixing bolt 21. The counterweight plate protective shell 22 is installed on the outside and fixed. A grease nipple is installed on the grease port 14 of the eccentric shaft structural plate.

[0036] Assembly of the execution and adjustment components: The tamping pick bracket 8 is hinged to the lower part of the lower bracket 6 by a pin, and the other end of the opening and closing cylinder 7 is connected to the top of the tamping pick bracket 8; the tamping pick 11 is fixed to the bottom of the fixed tamping pick seat and the deflection tamping pick seat by 3 high-strength bolts, and the rubber pad 10 is fixed to the side of the tamping pick bracket 8 near the rail; the two ends of the lifting leg cylinder 9 are respectively hinged to the reserved interface of the deflection tamping pick seat and the tamping pick bracket 8, and connected to the hydraulic valve 1 control pipeline.

[0037] Debugging and inspection: Connect the excavator boom to the upper support ear plate 2 with the pin to ensure a firm hinge; start the excavator and control the movement of each cylinder through the hydraulic valve 1 to check whether the rotary motor 3 rotates smoothly, whether the opening and closing cylinder 7 drives the tamping pick 11 to open and close properly, and whether the extension and retraction of the lifting leg cylinder 9 is flexible; add grease through the grease port 12 of the rotary motor and the grease port 14 of the eccentric shaft structure plate to ensure sufficient lubrication of all rotating parts.

[0038] The usage method is as follows: Connect and fix the assembled tamping machine to the excavator boom through the upper bracket ear plate 2, and check the sealing of each pipeline connection; plan the operation route according to the work area, clear large pieces of debris around the sleepers, and ensure that the tamping pick 11 can be inserted into the space unobstructed.

[0039] Start the excavator's power system, turn on the swing motor 3, and adjust the tamping pick 11 to align with the ballast layer on both sides of the sleeper; control the extension of the opening and closing cylinder 7 to open the tamping pick 11 to a suitable angle, and operate the excavator to insert the tamping pick 11 into the ballast layer at the bottom of the sleeper; start the hydraulic motor 15 to drive the eccentric shaft 18 to rotate at high speed and generate vibration, tamping time is 3-5 seconds per sleeper to ensure the ballast is compacted; control the hydraulic motor 15 to stop, the opening and closing cylinder 7 extends to drive the tamping pick 11 to retract, and operate the excavator to move to the next sleeper to repeat the operation.

[0040] When the operation reaches the turnout position, if it is detected that the tamping pick 11 on one side is blocked by the turnout switch machine or other structures and cannot be inserted, the hydraulic valve 1 controls the retraction of the lifting cylinder 9, which drives the deflection tamping pick seat to rotate upward at a suitable angle to avoid the obstacle. After that, the excavator is operated to adjust the position of the equipment so that the tamping pick 11 is aligned with the ballast layer. The lifting cylinder 9 is then controlled to extend and reset. After the tamping pick 11 is inserted into the ballast layer, the vibration tamping process of the conventional line is repeated. During the operation, the angle can be finely adjusted by the rotary motor 3 to ensure tamping coverage in the special angle area of ​​the turnout.

[0041] After each day's work is completed, clean the ballast dust off the equipment surface and add grease through the grease port 12 of the rotary motor and the grease port 14 of the eccentric shaft structure plate; check the wear of the tamping pick 11, and replace it in time if the wear of the head wedge structure exceeds the threshold; check whether the rubber pad 10 is damaged and whether the shock-absorbing pad 5 is aged and deformed, and replace it if necessary.
