Description

Technical Field

[0001] The invention belongs to the technical field of railway maintenance, in particular to a tamping device for ballasted railway. Background Art

[0002] In the current railway maintenance work, there is a large demand for small-scale, temporary line repair and tamping compaction operations. These operations usually occur when the window time is short and the budget is limited. Traditional tamping comprehensive operation vehicles cannot be used in these scenarios due to their large size and high cost. Therefore, railway maintenance personnel can only rely on portable tamping picks for manual hand-held operations. Although they can deal with problems in an emergency in the short term, they cannot meet the requirements of efficient and precise tamping due to their limitations.

[0003] At present, manual hand-held operation of portable tamping picks is difficult to achieve. Since factors such as tamping angle and position mainly depend on the operator's experience and physical strength, the tamping effect often varies from person to person and is difficult to maintain consistency. This manual operation method not only increases the labor intensity of the operator, but also makes it difficult to ensure the quality of tamping, resulting in unstable operation results and failure to achieve the ideal tamping compaction effect, which in turn affects the stability of the track structure and the safety of train operation. Summary of the invention

[0004] The object of the present invention is to provide a tamping device for ballasted railway to solve the problems mentioned above in the prior art.

[0005] Provided is a tamping device for ballasted railway, comprising a plurality of tamping assemblies, each tamping assembly comprising a chassis, the upper part of the chassis is rotatably connected to a transverse axis, the upper part of the transverse axis is slidably connected to a swing frame, tamping picks are arranged on both sides of the upper part of the swing frame, the upper part of the chassis is provided with a transverse mechanism, the transverse mechanism is used to drive the swing frame to move transversely along the transverse axis, the upper part of the transverse mechanism is provided with an angle adjustment mechanism, and the swing frame is provided with a lifting device for driving the tamping pick to move along the swing frame.

[0006] As a further embodiment of the present invention: the transverse movement mechanism includes a transverse movement frame, the transverse movement frame is arranged above the chassis, a transverse movement shaft is rotatably connected above the transverse movement frame, a transverse movement upper swing rod is fixedly connected above the transverse movement shaft, a transverse movement lower swing rod is also fixedly connected below the transverse movement shaft, both sides of the transverse movement lower swing rod are connected with sliding blocks through transverse movement flexible shafts, the sliding block is slidably connected to the transverse movement shaft, the upper part of the sliding block is fixedly connected with a swing frame, the transverse movement flexible shaft on the opposite side is tightened, and the other side is relaxed, and the transverse movement flexible shaft The driving sliding block pulls the swing frame as a whole to the left to achieve lateral left movement. The working mode of the lateral movement flexible shaft is similar to that of a bicycle brake line. One end of the lateral movement flexible shaft is fixed on the lateral movement lower swing rod, and the other end is fixed on both sides of the swing frame. When the lateral movement lower swing rod swings, the movement direction and distance of the swing frame are controlled by pulling or loosening the lateral movement flexible shaft. Through the swing of the lateral movement lower swing rod, the lateral movement flexible shaft repeatedly pulls the swing frame in the lateral direction, thereby adjusting the working position of the tamping pick. The operating range can be expanded without moving the entire chassis, thereby improving the operating efficiency and accuracy.

[0007] As a further embodiment of the present invention: the upper part of the transverse frame is also provided with a positioning plate, and the positioning plate is provided with a plurality of positioning holes. The transverse upper swing arm can change its angle by rotation. When the transverse upper swing arm rotates to the target position, the locking pin is inserted into the corresponding positioning hole to fix the transverse upper swing arm. After the locking pin is inserted, the further movement of the transverse upper swing arm is limited, thereby fixing the angle of the transverse lower swing arm. The fixing effect is transmitted to the transverse flexible shaft to keep the transverse state of the swing frame unchanged. When the position of the swing frame needs to be changed, the locking pin is pulled out, the transverse upper swing arm is adjusted to a new angle, and the corresponding positioning hole is inserted again to complete the new position setting. By inserting the locking pin into different positioning holes, the angle of the transverse upper swing arm can be selectively fixed, thereby indirectly controlling the swing range of the transverse lower swing arm and the pulling distance of the transverse flexible shaft, and then adjusting the swing frame to move horizontally along the transverse axis, so that the tamping pick can be accurately adjusted to the target position below the sleeper. Through the transverse movement, the device can cover different areas of the track to achieve uniform tamping.

[0008] As a further embodiment of the present invention: a locking pin for passing through the positioning hole is provided on the upper transverse swing arm. The locking pin is inserted into different positioning holes, and the angle of the upper transverse swing arm can be selectively fixed, thereby indirectly controlling the swing range of the lower transverse swing arm and the pulling distance of the transverse flexible shaft, and then adjusting the swing frame to move laterally along the transverse axis, so that the tamping pick can be accurately adjusted to the target position under the sleeper.

[0009] As a further embodiment of the present invention: the angle adjustment mechanism includes a screw base, which is arranged above the transverse frame, and an adjusting screw is rotatably connected to the screw base. The upper part of the adjusting screw is threadedly connected to a guide seat, and the guide seat is rotatably connected to a swing frame via a guide shaft. When the adjusting screw rotates, the threaded engagement between the adjusting screw and the guide seat drives the guide seat to move along the screw axis, and the movement of the guide seat drives the swing frame connected thereto to rotate around the guide shaft, thereby changing the angle of the swing frame. Since the threaded connection has a self-locking characteristic, after the adjusting screw stops rotating, the position of the guide seat remains unchanged, thereby fixing the angle of the swing frame. By rotating the adjusting screw, the moving distance of the guide seat can be accurately controlled, thereby achieving precise adjustment of the swing frame angle, which is suitable for scenarios where the tamping pick needs to operate at different sleeper positions or angles.

[0010] As a further embodiment of the present invention: a balancing shaft is also provided on one side of the upper part of the chassis. The balancing shaft is installed on one side of the upper part of the chassis and placed on the rails to provide additional support to prevent the entire device from tilting or shaking during operation.

[0011] As a further embodiment of the present invention: a balancing roller is arranged on the side of the upper part of the balancing shaft away from the chassis. The balancing roller facilitates the balancing shaft to approach the track surface and provides additional support, ensuring that the entire equipment does not tilt or shake due to center of gravity shift or vibration during operation, and maintains a stable state, thereby improving operation accuracy. The balancing roller can adjust its position by rolling according to track conditions (such as unevenness or slopes) and changes with terrain, avoiding equipment tilting or center of gravity shift, alleviating the impact force caused by vibration by rolling, and reducing direct impact on the balancing shaft and chassis.

[0012] As a further embodiment of the present invention: the tamping pick is provided with a throttle handle. When the throttle handle is pulled, the power of the tamping pick increases and the work intensity also increases accordingly; on the contrary, reducing the pulling degree of the throttle handle can reduce the power output and reduce the workload. By adjusting the power output, the throttle handle can reduce the energy consumption of the tamping pick when it does not need to run at full power, thereby effectively reducing the wear and loss of the machine and reducing maintenance costs.

[0013] As a further embodiment of the present invention: two adjacent tamping assemblies are connected by a connecting rod, which connects and fixes the tamping assemblies, ensuring the relative position and stability between the tamping assemblies. During operation, multiple tamping assemblies can work together to improve work efficiency. The tamping assemblies are connected on-site using a connecting rod, and the position of the tamping assemblies can be flexibly assembled and adjusted according to on-site needs, and multi-point tamping can be performed.

[0014] As a further embodiment of the present invention: travel rollers are arranged under the chassis, and the travel rollers facilitate moving the entire chassis on the rails.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The lifting device is installed on the swing frame and is used to drive the tamping pick to move up and down along the swing frame. During the tamping process, the lifting device presses the tamping pick into the ballast for operation, and lifts it to the initial position after completion, so that the device can move to the next operation point. In small-scale, temporary line repair and tamping compaction operations, the tamping angle and tamping position of the tamping pick can be adjusted. The device provides stable support through the chassis, uses the transverse axis and the swing frame to achieve precise positioning of the tamping pick, and combines the transverse mechanism and the angle adjustment mechanism to flexibly adjust the position and direction of the tamping pick. Driven by the lifting device, the tamping pick compacts the ballast under the sleeper, making the track structure more stable, ensuring the safety and stability of the train operation, and avoiding manual tamping that cannot ensure the tamping quality.

[0031] See also Figure 1-5 As shown, a tamping device for ballasted railway in an embodiment of the present invention comprises a plurality of tamping assemblies 100, each tamping assembly 100 comprises a chassis 1, a traverse shaft 2 is rotatably connected to the upper part of the chassis 1, a swing frame 3 is slidably connected to the upper part of the traverse shaft 2, tamping picks 4 are arranged on both sides of the upper part of the swing frame 3, a traverse mechanism 5 is arranged on the upper part of the chassis 1, the traverse mechanism 5 is used to drive the swing frame 3 to move transversely along the traverse shaft 2, an angle adjustment mechanism 6 is arranged on the upper part of the traverse mechanism 5, and a lifting device 7 for driving the tamping pick 4 to move along the swing frame 3 is arranged on the swing frame 3; (the specific structure of the lifting device 7 is a telescopic electric cylinder, the telescopic end of which is connected to the tamping pick 4 through a connecting block, the connecting block is slidably connected to the swing frame 3, and specifically the tamping pick 4 is driven to move along the swing frame 3 by the telescopic electric cylinder);

[0032] The transverse movement mechanism 5 is responsible for driving the swing frame 3 to move transversely along the transverse movement axis 2, so that the tamping pick 4 can be accurately adjusted to the target position under the sleeper. Through the transverse movement, the device can cover different areas of the track to achieve uniform tamping;

[0033] The angle adjustment mechanism 6 is used to adjust the angle of the swing frame 3, thereby changing the working direction of the tamping pick 4, and can adapt to the shapes and angle requirements of different sleepers and tracks, ensuring the flexibility and efficiency of the tamping operation.

[0034] The lifting device 7 is installed on the swing frame 3, and is used to drive the tamping pick 4 to perform lifting and lowering movements along the direction of the swing frame 3. During the tamping process, the lifting device 7 presses the tamping pick 4 into the ballast to perform operations. The specific lifting device 7 is and lifts it to the initial position after completion, so that the device can move to the next operating point. The tamping angle and tamping position direction can be adjusted through the angle adjustment mechanism 6 and the transverse movement mechanism 5. The transverse movement axis 2 and the swing frame 3 are used to achieve precise positioning of the tamping pick 4. The position and direction of the tamping pick 4 can be flexibly adjusted in combination with the transverse movement mechanism 5 and the angle adjustment mechanism 6. Driven by the lifting device 7, the tamping pick 4 compacts the ballast under the sleeper, making the track structure more stable, ensuring the safety and stability of the train operation, and avoiding manual tamping that cannot ensure the tamping quality.

[0035] In one embodiment, see Figure 1 and Figure 4 As shown, the transverse movement mechanism 5 includes a transverse movement frame 51, which is arranged above the chassis 1, and a transverse movement shaft 52 is rotatably connected to the top of the transverse movement frame 51, and a transverse movement upper swing rod 53 is fixedly connected to the top of the transverse movement shaft 52, and a transverse movement lower swing rod 54 is also fixedly connected to the bottom of the transverse movement shaft 52. Both sides of the transverse movement lower swing rod 54 are connected to sliding blocks 56 through transverse movement soft shafts 55, and the sliding blocks 56 are slidably connected to the transverse movement shaft 2. The upper part of the sliding block 56 is fixedly connected to the swing frame 3. When the transverse movement lower swing rod 54 swings to the left, one side of the transverse movement soft shaft 55 is tightened and the other side is relaxed. The tightened transverse movement soft shaft 55 pulls the swing frame 3 to the right as a whole through the sliding block 56 to complete the lateral right movement. When the transverse movement lower swing rod 54 swings to the right;

[0036] The transverse flexible shaft 55 on the opposite side is tightened and the other side is relaxed. The transverse flexible shaft 55 drives the sliding block 56 to pull the swing frame 3 as a whole to the left to achieve lateral left movement. The working mode of the transverse flexible shaft 55 is similar to that of a bicycle brake line. One end of the transverse flexible shaft 55 is fixed on the transverse lower swing rod 54, and the other end is fixed on both sides of the swing frame 3. When the transverse lower swing rod 54 swings, the movement direction and distance of the swing frame 3 are controlled by pulling or loosening the transverse flexible shaft 55. Through the swing of the transverse lower swing rod 54, the transverse flexible shaft 55 repeatedly pulls the swing frame 3 in the lateral direction, thereby adjusting the working position of the tamping pick 4. The operating range can be expanded without moving the entire chassis 1, thereby improving the operating efficiency and accuracy.

[0037] In one embodiment, see Figure 3 and Figure 4 As shown, a positioning plate 8 is also provided on the upper part of the transverse frame 51, and a plurality of positioning holes 81 are provided on the positioning plate 8. The transverse upper swing rod 53 can change its angle by rotation. When the transverse upper swing rod 53 rotates to the target position, the locking pin 9 is inserted into the corresponding positioning hole 81 to fix the transverse upper swing rod 53. After the locking pin 9 is inserted, the further movement of the transverse upper swing rod 53 is restricted, thereby fixing the angle of the transverse lower swing rod 54. The fixing effect is transmitted to the transverse soft shaft 55 to keep the transverse state of the swing frame 3 unchanged. When the position of the swing frame 3 needs to be changed, the locking pin 9 is pulled out. Locking pin 9, adjusts the upper transverse swing rod 53 to a new angle, and inserts the corresponding positioning hole 81 again to complete the new position setting. By inserting the locking pin 9 into different positioning holes 81, the angle of the upper transverse swing rod 53 can be selectively fixed, thereby indirectly controlling the swing range of the lower transverse swing rod 54 and the pulling distance of the transverse flexible shaft 55, and then adjusting the swing frame 3 to move laterally along the transverse axis 2, so that the tamping pick 4 can be accurately adjusted to the target position under the sleeper. Through the transverse movement, the device can cover different areas of the track to achieve uniform tamping.

[0038] In one embodiment, see Figure 3 and Figure 4 As shown, a locking pin 9 for passing through the positioning hole 81 is provided on the upper transverse swing rod 53. The locking pin 9 is inserted into different positioning holes 81, and can selectively fix the angle of the upper transverse swing rod 53, thereby indirectly controlling the swing range of the lower transverse swing rod 54 and the pulling distance of the transverse flexible shaft 55, and then adjusting the swing frame 3 to move laterally along the transverse axis 2, so that the tamping pick 4 can be accurately adjusted to the target position under the sleeper.

[0039] In one embodiment, see Figure 3 and Figure 4As shown, the angle adjustment mechanism 6 includes a screw base 61, which is arranged above the transverse frame 51, and an adjusting screw 62 is rotatably connected to the screw base 61. The upper part of the adjusting screw 62 is threadedly connected to a guide seat 63, and the guide seat 63 is rotatably connected to the swing frame 3 through a guide shaft 64. When the adjusting screw 62 rotates, the threaded engagement between the adjusting screw 62 and the guide seat 63 drives the guide seat 63 to move along the screw axis, and the movement of the guide seat 63 drives the swing frame 3 connected thereto to rotate around the guide shaft 64, thereby changing the angle of the swing frame 3. Since the threaded connection has a self-locking characteristic, after the adjusting screw 62 stops rotating, the position of the guide seat 63 remains unchanged, thereby fixing the angle of the swing frame 3. By rotating the adjusting screw 62, the moving distance of the guide seat 63 can be accurately controlled, thereby realizing accurate adjustment of the angle of the swing frame 3, which is suitable for scenarios where the tamping pick 4 needs to operate at different sleeper positions or angles.

[0040] In one embodiment, see Figure 1 A balancing shaft 10 is also provided on one side of the upper part of the chassis 1. The balancing shaft 10 is installed on one side of the upper part of the chassis 1 and is placed on the rails to provide additional support to prevent the entire device from tilting or shaking during operation.

[0041] In one embodiment, see Figure 1 As shown, a balancing roller 11 is provided on the upper side of the balancing shaft 10 away from the chassis 1. The balancing roller 11 provides additional support for the balancing shaft 10 to approach the track surface, ensuring that the entire equipment does not tilt or shake due to center of gravity shift or vibration during operation and maintains a stable state, thereby improving operation accuracy. The balancing roller 11 can adjust its position by rolling according to track conditions (such as unevenness or slopes) and changes in terrain to avoid equipment tilting or center of gravity shift, and alleviate the impact force caused by vibration by rolling, thereby reducing direct impact on the balancing shaft 10 and the chassis 1.

[0042] In one embodiment, see Figure 1 As shown, the tamping pick 4 is provided with a throttle handle 12, and the throttle handle 12 enables the user to adjust the output power of the tamping pick according to actual needs. When the throttle handle 12 is pulled, the power of the tamping pick 4 increases, and the work intensity also increases accordingly; on the contrary, reducing the pulling degree of the throttle handle 12 can reduce the power output and reduce the workload. By adjusting the power output, the throttle handle 12 can reduce the energy consumption of the tamping pick 4 when full power operation is not required, thereby effectively reducing the wear and loss of the machine and reducing maintenance costs. Since the power output can be flexibly adjusted according to work requirements, the throttle handle 12 helps to avoid unnecessary energy waste. When working under light load, reducing the power output can effectively save energy and improve energy utilization efficiency.

[0043] In one embodiment, see Figure 1and Figure 4 As shown, two adjacent tamping assemblies 100 are connected by a connecting rod 101, and two adjacent tamping assemblies 100 are connected by the connecting rod 101 to form an overall working system. The connecting rod 101 plays a role in connecting and fixing the tamping assemblies 100, ensuring the relative position and stability between the tamping assemblies 100. During operation, multiple tamping assemblies 100 can work together to improve work efficiency. The tamping assemblies 100 are connected on-site using the connecting rod 101, and the position of the tamping assemblies 100 can be flexibly assembled and adjusted according to on-site needs, and multi-point tamping can be performed.

[0044] In one embodiment, see Figure 1 and Figure 4 As shown, travel rollers 13 are provided below the chassis 1, and the travel rollers 13 facilitate moving the entire chassis 1 on the rails.

[0045] Specific steps for using the device: 1. Lift the chassis 1 onto the rails, and place the running wheels at the end of the balancing shaft 10 on the rails on the other side to prevent overturning, ensuring that the equipment is in a stable state before starting to avoid accidents during operation;

[0046] Step 2: Install the portable tamping pick 4 onto the swing frame 3, adjust the angle adjustment mechanism 6 to tilt the swing frame 3 to the fixed marking line, corresponding to a 30° tilt angle. The setting of the fixed marking line provides a clear adjustment reference, reduces human errors, and improves operation consistency.

[0047] Step 4: Push the whole rail to the tamping position, turn on the tamping pick 4, and the lifting device 7 drives the tamping pick 4 to insert into the ballast bed. After tamping for three seconds, it automatically rises and falls to gradually complete the tamping operation of the entire sleeper to ensure that the operation area is not missed.

[0048] Step 5: Pull out the locking pin 9, adjust the transverse mechanism 5, pull the swing frame 3 80 mm to the left along the transverse axis 2, and then repeat the tamping action of "Step 4", move and operate according to the preset position, and finally complete all tamping tasks in this area to provide stable support for the track.

[0049] Step 6: Pull out the locking pin 9, adjust the transverse movement mechanism 5, pull the swing frame 3 along the transverse movement axis 2 to move 80 mm to the left and 160 mm to the right, and then repeat the tamping action of "Step 4" to complete the tamping operation in this area.
