Description

Technical Field

[0001] This application relates to a track lifting and tamping device and a tamping machine, belonging to the field of railway maintenance machinery design and manufacturing technology. Background Technology

[0002] During railway operation, due to the repeated action of various alternating loads over a long period of time, the geometric dimensions of the track will undergo slight changes, resulting in deviations in the horizontal direction and vertical direction, which in severe cases may even affect the safety of train operation.

[0003] The track lifting and aligning device is one of the core components of the tamping machine, used for track lifting and aligning operations. Due to the complex structure of track lines, varying train speeds and load requirements, and different track types used in railways, existing track lifting and aligning devices cannot meet the requirements for lifting all turnouts. Therefore, it is necessary to develop a track lifting and aligning device that can adapt to various turnouts. Summary of the Invention

[0008] A reset mechanism is connected to the starting mechanism and the position adjustment mechanism;

[0009] The track-setting mechanism is connected to the main frame via a position adjustment mechanism, forming at least one hinge point. The track-setting mechanism rotates vertically along the hinge point under the track-setting force, and swings along the hinge point under the track-setting force.

The restoring force of the reset mechanism is transmitted to the track-setting mechanism, causing the track-setting mechanism to reset.

[0010] The position adjustment mechanism includes a traction member connected to the reset mechanism; the traction member swings under the action of a force, and the reset mechanism deforms under the force transmitted by the traction member; the restoring force of the reset mechanism is transmitted to the traction member, causing the traction member to reset.

In the clamping state, the swinging member drives the two clamping arms to swing, so that the two clamping members move closer to each other to clamp the track, and the second lifting member drives the second connecting member to rise and fall. In the releasing state, the swinging member drives the two clamping arms to swing, so that the two clamping members move further apart from each other to release the track.

[0022] In an exemplary embodiment, the clamping member includes a rail clamping wheel, a threaded sleeve, a bearing, a shaft, a nut, and a locking member. The shaft is disposed inside the rail clamping wheel and extends from one end of the rail clamping wheel. The nut is sleeved on the end of the shaft that extends from the rail clamping wheel. The threaded sleeve is sleeved on the shaft and located below the nut. The bearing is located outside the shaft and inside the threaded sleeve. The locking member is disposed between the nut and the threaded sleeve.

[0023] In an exemplary embodiment, the track lifting frame includes a first connecting part and a second connecting part. The second track lifting assembly has two sets. The two sets of the second track lifting assembly are disposed in the first connecting part, and the first track lifting assembly is disposed in the second connecting part and located between the first connecting part and the second connecting part.

[0024] In an exemplary embodiment, the first connecting portion includes a lifting plate and a first mating portion, the lifting plate being movable on the first mating portion, and the second connecting member being connected to the second lifting member through the lifting plate, the second lifting member being raised and lowered to drive the clamping member to be raised and lowered.

[0025] In an exemplary embodiment, the second connecting portion includes a second mating portion, the first connecting member is slidably connected to the second mating portion, and the first connecting member reciprocates on the second mating portion under the action of a force.

[0026] In one exemplary embodiment, the position adjustment mechanism includes:

[0027] A hollow assembly, through which the traction member protrudes;

[0028] The second moving part is connected at one end to the traction part and at the other end to the mating body;

[0029] One of the traction component and the mating body is fixedly connected to the main frame, and the other is rotatably connected to the lifting track frame; the second moving component drives the traction component to move within the mating body.

[0030] In an exemplary embodiment, the mating body includes a cavity, a first plate, a second plate, and an adjusting member. The first plate and the second plate are both disposed within the cavity. The first plate is disposed on the inner wall of the cavity, and the second plate is located on both sides of the first plate to restrict the first plate from moving out of the cavity. One end of the adjusting member extends from the outer wall of the cavity into the inner wall of the cavity to contact the first plate, and the other end is located on the outer side of the outer wall of the cavity. Adjusting the adjusting member adjusts the distance between the first plate and the inner wall of the cavity.

[0031] The traction component can slide within the cavity under the applied force.

[0032] According to a second aspect of the embodiments of this application, a tamping machine is provided, comprising:

[0033] As described above, the track-setting device

The reset mechanism is connected to the track-setting mechanism and the position adjustment mechanism. The track-setting mechanism is connected to the main frame through the position adjustment mechanism, forming at least one hinge point. The track-setting mechanism rotates vertically along the hinge point under the track-setting force, and the track-setting mechanism rotates along the hinge point under the track-setting force. The oscillation mechanism and the reset mechanism are deformed by the force transmitted by the oscillation of the track-setting mechanism.

The position adjustment mechanism includes a traction component connected to the reset mechanism. The traction component oscillates under the action of the force, and the reset mechanism deforms under the force transmitted by the traction component. The restoring force of the reset mechanism is transmitted to the traction component, causing it to reset. The position adjustment mechanism includes a traction component, which oscillates under the action of the force.

[0053] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0054] In the process of developing this application, the inventors discovered that existing track lifting and shifting devices cannot meet the requirements of all turnouts for track lifting operations. Therefore, it is necessary to develop a track lifting and shifting device that can adapt to a variety of turnouts.

[0055] To address the aforementioned problems, this application provides a track-lifting device suitable for tamping machines, such as... Figure 1 and Figure 2As shown, the tamping machine has a main frame 1, including a track-raising mechanism, a position adjustment mechanism 2 connected to the track-raising mechanism, and a reset mechanism 3 connected to the position adjustment mechanism 2. The position adjustment mechanism 2 includes a traction member 21, which is connected to the reset mechanism 3. One end of the traction member 21 is connected to the track-raising mechanism, and the other end is connected to the main frame 1. The traction member 21 swings under the action of force. Due to the connection between the traction member 21 and the reset mechanism 3, the reset mechanism 3 is deformed by the force transmitted by the traction member 21. The restoring force of the reset mechanism 3 is transmitted to the traction member 21, which drives the traction member 21 to reset.

[0056] Preferably, the reset mechanism 3 includes a first reset mechanism and a second reset mechanism, which are located on opposite sides of one end of the traction member 21. When operating on a curve, the traction member 21 is subjected to a force and swings toward the first reset mechanism. The first reset mechanism is subjected to a force that causes deformation and compression, while the second reset mechanism is subjected to a force that causes deformation and stretching. When the operation is completed and the device is retracted, the compression and restoring forces of the first and second reset mechanisms work together to drive the traction member 21 to swing toward the second reset mechanism until it is reset to a perpendicular state between the traction member 21 and the track-lifting frame 6. That is, neither the first nor the second reset mechanism has deformed, thus completing the locking action of the track-lifting device. The reverse is also true.

[0057] Furthermore, such as Figure 5 As shown, the reset mechanism includes an elastic element 31, an adjusting component 32, an abutting part 33, and a mounting base 34. The abutting part 33 abuts against the traction member 21. One end of the elastic element 31 abuts against the abutting part 33, and the other end abuts against the mounting base 34. The adjusting component 32 is provided on the mounting base 34 and is used to adjust the elastic force of the elastic element 31.

[0058] The adjustment assembly 32 includes an adjustment member 321 and a shaft 322. The adjustment member 321 is disposed on the mounting base 34, and the shaft passes through at least part of the elastic member 31. One end of the shaft is connected to the abutment portion 33, and the other end is connected to the mounting base 34. The adjustment member 321 is rotatably connected to the shaft. Rotating the adjustment member 321 causes the mounting base 34 to move closer to or further away from the abutment portion 33, thereby adjusting the compression amount of the elastic member 31.

[0059] Preferably, the elastic element 31 is a spring, and the adjusting element 321 is an adjusting nut 4255. The adjusting nut 4255 is threaded to the shaft. By rotating the adjusting nut 4255 on the shaft, the distance between the mounting base 34 and the abutment part 33 can be adjusted, thereby adjusting the compression of the spring. It is understood that the elastic element 31 may include, but is not limited to, springs, sponges, or other devices with elastic force and restoring force.

[0060] Furthermore, such as Figure 4As shown, the track-setting mechanism includes a track-setting frame 6 connected to the position adjustment mechanism 2, a track-setting mechanism 4 mounted on the track-setting frame 6, and a track-setting mechanism with one end mounted on the track-setting frame 6 and the other end connected to the main frame 1; the track-setting mechanism generates a force to drive the track-setting frame 6 to swing, so that the track-setting mechanism 4 swings relative to the track.

[0061] Specifically, the track-shifting mechanism includes a track-shifting component 51. One end of the track-shifting component 51 is fixedly connected to the main frame 1, and the other end is rotatably connected to the track-shifting frame 6. The track-shifting component 51 generates a force to drive the track-shifting frame 6 to swing to one side or retract. There are two track-shifting components 51, each connected to the track-shifting frame 6. At least one track-shifting component 51 generates a force to drive the track-shifting frame 6 to swing and adjust the swing amplitude. The track-shifting component 51 can be a structure with telescopic swinging function, such as a luffing cylinder or a pneumatic cylinder.

[0062] Furthermore, such as Figure 3 As shown, the track lifting mechanism 4 includes a first track lifting assembly 41, which includes a first lifting member 411, a track lifting member 412, a first moving member 413, and a first connecting member 414. The first moving member 413 is connected to the first lifting member 411, and the first connecting member 414 is located on the track lifting frame 6. The track lifting member 412 is located on the track lifting frame 6. One end of the first lifting member 411 is connected to the track lifting member 412, and the other end is connected to the main frame 1. The first moving member 413 drives the track lifting member 412 to reciprocate along a direction perpendicular to the track to adjust the position of the track lifting member 412 relative to the track. The first lifting member 411 drives the track lifting member 412 to rise and fall to achieve track lifting. Specifically, the track lifting member 412 is a track lifting hook used to hook the bottom of the track to achieve track lifting operation.

[0063] Furthermore, such as Figure 6 As shown, the track lifting mechanism 4 also includes a second track lifting assembly 42, which includes a second connector 421, a second lifting member 422, a swing member 423, a clamping arm 424, and a clamping member 425. One end of the second lifting member 422 is connected to the main frame 1, and the other end is connected to the second connector 421. The clamping arm 424 is connected to the second connector 421, and one end of the swing member 423 is connected to the clamping arm 424, and the other end is connected to the second connector 421. The clamping member 425 is located at the end of the clamping arm 424. The assembly includes two clamping arms 424 and two clamping members 425. The second track-lifting assembly 42 has a clamping state and a releasing state. In the clamping state, the swing member 423 drives the two clamping arms 424 to swing so that the two clamping members 425 move closer to each other to clamp the track jaws. The second lifting member 422 drives the second connecting member 421 to lift and lower to achieve track lifting. In the releasing state, the swing member 423 drives the two clamping arms 424 to swing so that the two clamping members 425 move further apart to release the track jaws.

[0064] Specifically, such as Figure 7As shown, the clamping component 425 includes a clamping wheel 4251, a threaded sleeve 4252, a bearing 4253, a shaft 4254, a nut 4255, and a locking component 4256. The shaft 4254 is located inside the clamping wheel 4251 and extends from one end of the clamping wheel 4251. The nut 4255 is fitted onto the end of the shaft 4254. The threaded sleeve 4252 is fitted onto the shaft 4254 and located below the nut 4255. The bearing 4253 is located outside the shaft 4254 and inside the threaded sleeve 4252. The locking component 4256 is located between the nut 4255 and the threaded sleeve 4252 to achieve locking. By rotating the nut 4255 and the threaded sleeve 4252, the clamping wheel 4251 can be disassembled, realizing the replaceability of the worn parts. The locking component 4256 can be a stop washer or other components with locking functions.

[0065] When performing track lifting operations, depending on the track rail structure, the lifting hook can be used to hook onto the bottom of the rail and lift it using the first lifting component 411; or the double clamping components 425 on both sides can be used to clamp the rail jaws and lift it using the second lifting component 422 to complete the track lifting operation, which has good flexibility and mobility.

[0066] Furthermore, the track lifting frame 6 includes a first connecting part 61 and a second connecting part 62. The second track lifting assembly 42 has two sets. The two sets of second track lifting assemblies 42 are disposed on the first connecting part 61, and the first track lifting assembly 41 is disposed on the second connecting part 62 and located between the first connecting part 61 and the second connecting part 62.

[0067] The first connecting part 61 includes a track-lifting plate 611 and a first mating part 612. The track-lifting plate 611 is slidably connected to the first mating part 612, and the track-lifting plate 611 can slide on the first mating part 612. The second connecting member 421 is connected to the second lifting member 422 through the track-lifting plate 611. The driving force of the second lifting member 422 is transmitted to the second connecting member 421 through the track-lifting plate 611, thereby driving the clamping member 425 to rise and fall. The clamping member 425 clamps the rail jaw to realize the track-lifting operation. Optionally, the second lifting member 422 can be a component with driving force, such as a cylinder, hydraulic cylinder, or motor, that can realize lifting.

[0068] Furthermore, the second connecting part 62 includes a second mating part 621, and the first connecting member 414 is slidably connected to the second mating part 621. The first connecting member 414 moves back and forth on the second mating part 621 under the action of force, thereby increasing the stroke of the track lifting member 412. This can effectively avoid the situation of difficulty in recovery after the track lifting member 412 has reached its maximum stroke. It achieves an increase of 45mm on one side of the maximum stroke of the track lifting member 412 on the original basis without increasing the overall width, and the maximum center distance of the track lifting member 412 can reach 3163mm.

[0069] The first connecting member 414 has through holes 415 at both ends, and the second mating part 621 has guide post mounting holes 416. A guide post is installed in the guide post mounting holes 416 and passes through the through holes 415 of the first connecting member 414, so that the first connecting member 414 moves along the guide post under the action of force. Optionally, one of the first connecting member 414 and the second mating part 621 can be provided with a guide rail, and the other can be provided with a pulley, with the pulley sliding along the guide rail. Alternatively, one of the first connecting member 414 and the second mating part 621 can be provided with a fixed slide rail, and the other can be a movable slide rail, with the movable slide rail sliding on the fixed slide rail.

[0070] Furthermore, the position adjustment mechanism 2 includes: a mating body 22, which is hollow and allows the traction member 21 to pass through it; and a second moving member 23, one end of which is connected to the traction member 21 and the other end of which is connected to the mating body 22; one of the traction member 21 and the mating body 22 is fixedly connected to the main frame 1, and the other is rotatably connected to the lifting rail frame 6; the second moving member 23 drives the traction member 21 to move within the mating body 22, thereby moving the lifting rail frame 6 and achieving position adjustment when using the lifting hook or clamp. Optionally, the second moving member 23 can be a hydraulic cylinder, pneumatic cylinder, motor, or other driveable component.

[0071] Furthermore, such as Figure 8 As shown, the mating body 22 includes a cavity 221, a first plate 222, a second plate 223, and an adjusting member 224. Both the first plate 222 and the second plate 223 are located within the cavity 221. The first plate 222 is detachably mounted on the left, right, and upper inner walls of the cavity 221. The second plate 223 is located on both sides of the first plate 222 to limit its passive movement out of the cavity 221 under the force of the traction member 21, thus serving a limiting function. One end of the adjusting member 224 penetrates from the outer wall of the cavity 221 into the inner wall to abut against the first plate 222, while the other end is located on the outer side of the outer wall of the cavity 221. The adjusting member 224 is adjusted to adjust the distance between the first plate 222 and the inner wall of the cavity 221. The traction member 21 can slide within the cavity 221 under the applied force.

[0072] Specifically, the adjusting element 224 can be a combination of bolts and screws. The length of the screw in the cavity 221 can be adjusted by turning the screw knob, thereby adjusting the distance between the first plate 222 and the inner wall of the cavity 221, and also facilitating the disassembly of the first plate 222. The first plate 222 is a wear-resistant nylon plate, and the second plate 223 is detachable to facilitate the replacement of the first plate 222. There are multiple adjusting elements 224, which are distributed on the top and side surfaces of the mating body 22.

[0073] According to a second aspect of the embodiments of this application, a tamping machine is provided, including: the above-mentioned track lifting device; a main frame 1, the track lifting device being connected to the main frame 1; and a main control device electrically connected to the track lifting device.

[0074] The main lifting mechanism controls the lifting components 412 of each of the left and right lifting mechanisms 4 to clamp the left and right rails respectively. Each lifting mechanism 4 can be controlled independently. For ordinary lines and main lines before and after turnouts, the tamping car uses a set of clamping components 425 on each side to clamp the left and right rails for lifting operations. When traveling straight in the switch area, the wheel load acts on the straight main rail and the straight switch rail. Because the switch rail is closely fitted to the main rail and is relatively fragile and easily damaged, the clamping components 425 cannot clamp the switch rail for operation. At this time, the left and right lifting components 412 are used to lift the straight main rail and the curved main rail respectively. During the lifting operation, depending on the rail structure, the lifting component 412 can be hooked onto the bottom of the rail or the clamping component 425 can be clamped onto the rail jaw. The lifting operation is completed by lifting with the lifting cylinder, which has good flexibility and maneuverability.
