Description

Technical Field

[0001] The present invention relates to a tamping car applicable to turnout operation and a tamping operation method, belonging to the technical field of railway maintenance machinery design and manufacturing. Background Art

[0002] A tamping car is a large-scale track maintenance machine used to eliminate track deviations and tamp the ballast under the sleepers during the construction of new railway lines and line maintenance operations. Its working device usually includes a measuring device for detecting the line, a lifting and lining device for correcting the line, and a tamping device for tamping the ballast under the sleepers.

[0003] When the tamping car is used for turnout operation, its working device needs to be designed adaptively. For example, the tamping device needs to perform large-range rotation and transverse movement, and thus a rotatable and transversable tamping frame needs to be designed. The current rotatable and transversable frame has the disadvantages of being too large in structure or having a small movement range. In the lifting and lining device, the lifting wheels and lifting hooks are designed at different positions, and their control and operation are independent of each other, resulting in the disadvantages of non-compact structure and complex operation. The tamping device has the characteristics of relatively single structure type, and some tamping devices have low working reliability due to overly complex structure. Therefore, it is necessary to develop a tamping car applicable to turnout operation that solves the above problems and has the characteristics of simple and compact structure, reliable work, high engineering application value, etc.

[0004] For example, Chinese Patent No. CN1056140A discloses a track tamping machine with a transversable tamping unit. A traveling track tamping machine with four tamping units arranged on both sides of the rail and capable of moving transversely along the track is equipped with a tamping mechanism that can open and close and vibrate. The tamping mechanism is installed on a tool carrier beam connected to the tool frame and adjustable in height along the guide rail. The tool frame of each outer tamping unit on the mechanical transverse direction is installed on the tool frame of the adjacent inner tamping unit arranged in the mechanical transverse direction. At the same time, the tool frame of the outer tamping unit can be moved a certain distance away from the tool frame of the inner tamping unit along the track transverse direction by using a displacement driving mechanism, and the two inner tamping units can move independently on the transverse guide rails that are horizontally transverse to the longitudinal direction of the machine. However, its working reliability is relatively low. Summary of the Invention

[0005] The present invention provides a tamping car applicable to turnout operation, and its working device, especially the tamping device, the lifting and lining device, and the rotatable and transversable frame, have the advantages of simple and compact structure, wide operation range, reliable work, high engineering application value, etc.

[0006] A tamping car applicable to turnout operation, comprising a vehicle body, a lifting and lining device, a tamping device, and a rotating and traversing frame. The lifting and lining device is connected below the vehicle body, the tamping device is connected to the rotating and traversing frame, and the rotating and traversing frame is connected to the vehicle body. The lifting and lining device includes lifting wheels and lifting hooks, which are interconnected and both connected to a lifting switching mechanism, and the attitude is changed through the lifting switching mechanism.

[0007] The tamping device adopts an eccentric vibration shaft structure arranged vertically and is installed on the rotating and traversing frame. The traversing device of the rotating and traversing frame adopts a movable fulcrum structure. The rotating and traversing frame includes a first traversing beam, a second traversing beam, and a movable fulcrum.

[0008] The vehicle body of the tamping car includes a tamping operation vehicle and a material vehicle, which are interconnected. The tamping operation vehicle includes a front driver's cab, an operation driver's cab, a tamping operation vehicle frame, and a tamping operation vehicle roof. The material vehicle includes a rear driver's cab, a material vehicle frame, a material vehicle roof, and a material hopper.

[0009] The tamping car further includes a running system, a power system, a measuring system, and an auxiliary lifting device. The running system and the power system are used to provide power for vehicle running and operation. The measuring system is used to detect track parameter deviations and guide tamping operations. The auxiliary lifting device is used to assist the lifting operation in the turnout area.

[0010] The lifting and lining device mainly includes a lifting and lining frame, a lifting device, and a lining device. The lifting device and the lining device are installed on the lifting and lining frame. The lifting device includes lifting wheels and lifting hooks. The lifting wheels and the lifting hooks are both connected to a lifting switching mechanism, and the working attitudes of the lifting wheels and the lifting hooks are changed through the lifting switching mechanism. The lining device includes a lining driving mechanism and lining wheels. The lining driving mechanism drives the lining wheels to move laterally to achieve the lining operation.

[0011] The lifting and lining device further includes a lifting and lining position adjusting mechanism and a frame mounting seat. One end of the frame mounting seat is connected to the body of the track maintenance machine, and a guide post is installed at the other end. The lifting and lining position adjusting mechanism is connected between the frame mounting seat and the lifting and lining frame. Under the pushing or pulling action of the lifting and lining position adjusting mechanism, the entire lifting and lining frame moves along the guide post, so as to realize the adjustment of the lifting and lining position in the X direction.

[0012] The lifting device further includes a lifting driving mechanism, a lifting traversing mechanism, and a lifting hook moving mechanism. The lifting driving mechanism makes the lifting and lining frame move vertically to achieve the lifting operation. The lifting traversing mechanism makes the lifting wheels and the lifting hooks move laterally to adapt to the lifting operation in curves and turnout areas. The lifting hook moving mechanism is used to move the lifting hook to realize the hooking action of the lifting hook on the rail head and the rail bottom.

[0013] The tamping device includes an excitation device, a clamping and opening drive device, and a clamping device. The excitation device mainly includes a rotational power source, a vibration shaft component, and an energy storage device, which are arranged vertically in sequence. The vibration shaft component adopts an eccentric vibration structure, and the rotation axis is vertical. The clamping device includes clamping arms, inner pick arms, outer pick arms, a pick-up driving device, and clamping picks. The inner pick arms and the outer pick arms can be separately lifted under the action of the pick-up driving device, and clamping picks are installed on both the inner pick arms and the outer pick arms, thereby realizing the lifting action of the clamping picks. The clamping and opening drive device is connected to the clamping device through a joint. The joint includes two kinematic pairs, namely, a rotation axis perpendicular to the movement plane of the clamping device and a rotation axis parallel to the movement plane of the clamping device, for transmitting the effective-direction vibration generated by the excitation device and eliminating the ineffective-direction vibration. The tamping device further includes a box body and guide columns for support and operation guidance. The tamping device further includes a lubrication system for lubricating rotating components.

[0014] The rotary and traversing frame includes a rotary device, a traversing device, a frame cavity, and an operation unit mounting rack. The frame cavity includes a fixed cavity and a rotary cavity. The fixed cavity is fixedly connected to the body of the tamping car, and the rotary cavity is arranged inside the fixed cavity and can move relative to the fixed cavity. The rotary device includes a fixed beam, a rotary beam, a rotary shaft, and a rotary drive device. The fixed beam is connected to the body of the tamping car. The fixed beam and the rotary beam are connected by the rotary shaft. The rotary drive device drives the rotary beam to rotate relative to the fixed beam with the rotary shaft as the center. At the same time, the rotary beam is also connected to the rotary cavity, thereby transmitting the rotary motion of the rotary beam to the rotary cavity. The traversing device includes a first traversing beam, a second traversing beam, a movable fulcrum, an end plate, a fulcrum guide column, a traversing drive device, and a fulcrum drive mechanism. The first traversing beam is installed inside the rotary cavity, and the traversing drive device causes the first traversing beam to perform a traversing action relative to the rotary cavity. One end of the second traversing beam is connected to the end of the first traversing beam through the end plate. The other end of the second traversing beam is installed with the movable fulcrum, and at the same time, the movable fulcrum is nested and installed on the fulcrum guide column and can move along the fulcrum guide column. The fulcrum guide column is installed outside the rotary cavity. This structure enables the fulcrum of the second traversing beam to change with the change of the traversing position, thereby making the traversing range wider. The operation unit mounting rack is installed on the second traversing beam. The operation unit mounting rack includes an operation unit traversing guide sleeve and an operation unit traversing drive mechanism. The operation unit traversing drive mechanism enables the operation unit mounting rack to traverse along the second traversing beam.

[0015] Preferably, the movable fulcrum is further connected to the fulcrum drive mechanism, so that the movable fulcrum moves along the fulcrum guide column to realize the active adjustment of the position of the movable fulcrum.

[0016] More preferably, the movable fulcrum includes two guide groove structures. The first guide groove is a circular through-hole in the center of a rectangular block. The outer side of the rectangular block is connected to the edge of the second guide groove through two arc plates. The second guide groove is formed by connecting two semi-circular arch structures into one body, and a circular through-hole is formed in the center of the semi-circular arch. After the two semi-circular arches are connected, they are connected to the rectangular block of the first guide groove through the two arc plates. The axes of the circular through-holes of the first guide groove and the second guide groove are parallel; the first guide groove is located below the second guide groove.

[0017] A second transverse moving beam is installed in the first guide groove, and a fulcrum guide post is installed in the second guide groove.

[0018] The second aspect of the present invention provides a rotary transverse moving frame with another structural form.

[0019] The rotary transverse moving frame includes an inner rotary transverse moving device, an outer rotary transverse moving device, and an operation unit mounting rack.

[0020] The inner rotary transverse moving device includes an inner rotary device and an inner transverse moving device. The inner rotary device includes an inner fixed beam, an inner rotary beam, an inner rotary shaft, an inner fixed frame, an inner rotary frame, and an inner rotary driving mechanism. Both the inner fixed beam and the inner fixed frame are fixed to the body of the road maintenance machine, and the inner rotary beam is fixedly connected to the inner rotary frame. The inner fixed beam and the inner rotary beam are connected by the inner rotary shaft. When the inner rotary driving mechanism acts, the inner rotary beam will drive the inner rotary frame to rotate around the inner rotary shaft, thereby realizing the rotary motion. The inner transverse moving device includes an inner transverse moving guide post, an inner transverse moving guide sleeve, and an inner transverse moving driving mechanism. An inner operation unit mounting rack is installed on the inner transverse moving guide sleeve and can slide along the inner transverse moving guide post under the action of the inner transverse moving driving mechanism. The inner transverse moving guide post is connected to the inner rotary frame, so when the inner rotary frame rotates, the inner transverse moving guide post also rotates, thereby driving the inner operation unit mounting rack to rotate.

[0021] The outer rotary transverse moving device includes an outer rotary device and an outer transverse moving device. The outer rotary device includes a first outer rotary shaft, a first outer rotary driving mechanism, a second outer rotary shaft, and a second outer rotary driving mechanism.

[0022] The outer transverse moving device includes an outer telescopic arm and an outer transverse moving driving mechanism. One end of the outer telescopic arm is hinged to the body of the tamping car through the first outer rotary shaft, and the other end is hinged to the outer operation unit mounting rack through the second outer rotary shaft. The outer telescopic arm includes a multi-layer guide sleeve structure and undergoes telescopic changes under the action of the outer transverse moving driving mechanism to realize the transverse moving action. The outer telescopic arm rotates around the first outer rotary shaft under the action of the first outer rotary driving mechanism to realize the rotary motion. When the second outer rotary driving mechanism acts, it drives the outer operation unit mounting rack to rotate around the second outer rotary shaft to realize a further rotary motion.

[0023] The third aspect of the present invention provides a tamping operation method, which combines the tamping vehicle provided by the present invention / invention applicable to turnout operation to perform tamping operation on the line, especially the tamping operation in the turnout area.

[0024] Combined with the structural scheme of the tamping vehicle provided by the present invention, the preferred scheme of the tamping operation method will be described:

[0074] Example 1.1: A tamping car applicable to turnout operation, as Figure 1 shown, the tamping car includes a vehicle body 1. An alignment and lifting device 7 and a rotary and lateral translation frame 9 are installed under the frame of the vehicle body 1. A tamping device 8 is installed under the rotary and lateral translation frame 9. The tamping operation vehicle includes a tamping car body 1 and a material car 2, which are connected to each other. A front driver's cab 11 is installed on the tamping car body 1. An operation driver's cab 12 is installed in the middle of the tamping car body 1. The tamping car body 1 is connected to the frame of the tamping operation vehicle 13 at the lower part, and a roof 14 of the tamping operation vehicle is installed above the tamping car body 1. The material car 2 includes a rear driver's cab 21, which is installed on the frame 22 of the material car. A roof 23 of the material car is also connected above the rear driver's cab 21. A material hopper 24 is installed on the frame 22 of the material car.

[0075] The tamping car body 1 further includes a running system 3, a power system 4, a measurement system 5, and an auxiliary lifting device 6. The running system 3 and the power system 4 are used to provide power for vehicle running and operation. The measurement system 5 is used to detect the deviation of track parameters and guide the tamping operation. The auxiliary lifting device 6 is used to assist the lifting operation in the turnout area.

[0076] Figure 3 For Figure 1Structure diagram of the lifting and lining device 7 of the shown tamping car. The lifting and lining device 7 includes a lifting and lining frame 71, a lifting device 72, a lining device 73, a lifting and lining position adjusting mechanism 74, and a frame mounting seat 75. One end of the frame mounting seat 75 is connected to the body of the track maintenance machine, and the other end is equipped with a guide post 76, which is nested and connected to the lifting and lining frame 71. The lifting and lining position adjusting mechanism 74 is connected between the lifting and lining frame and the frame mounting seat 75. Under the action of the lifting and lining position adjusting mechanism 74, the entire lifting and lining frame 71 moves along the guide post 76, thereby realizing the displacement adjustment of the lifting and lining position along the X direction. The lifting and lining frame 71 is connected to the lining device 73 and the lifting device 72. The lining device 73 and the lifting device 72 are both arranged symmetrically about the X-direction center axis of the lifting and lining frame 71.

[0077] The lifting device 72 includes a lifting drive mechanism 721, a lifting transverse movement mechanism 722, a lifting wheel 723, a lifting hook 724, a lifting switching mechanism 725, a lifting hook movement mechanism 726, a lifting transverse movement guide post 727, and a rotating mounting block 728. In this embodiment, two sets of lifting devices 72 are arranged symmetrically about the Y direction to perform lifting operations on two rails respectively. One end of the lifting drive mechanism 721 of the lifting device 72 is connected to the body of the track maintenance machine, and the other end is connected to the lifting and lining frame 71. The lifting drive mechanism 721 is connected to the lower part of the lifting and lining frame 71. The lifting hooks 724 and the lifting wheels 723 are symmetrically arranged about the Y direction on the lifting and lining frame 71. Under the action of the lifting drive mechanism 721, the lifting and lining frame 71 moves along the Z direction, and then drives the lifting wheel 723 or the lifting hook 724 to move along the Z direction to realize the lifting operation; one end of the lifting transverse movement mechanism 722 is connected to the lifting and lining frame 1, and the other end is connected to the lifting wheel 723 and the lifting hook 724. The lifting transverse movement guide post 727 is installed at the lower part of the lifting and lining frame 71 below the lifting drive mechanism 721. The outer part of the lifting transverse movement guide post 727 is sleeved with a rotating mounting block 728. The rotating mounting block 728 includes a transverse movement guide post mounting hole 281 in the Y direction, a through hole 282 for the lifting hook installation along the Z direction, and a lifting wheel installation hole 283 along the X direction. The lifting wheel 723 is installed in the lifting wheel installation hole 283, and the lifting hook 724 is installed in the lifting hook installation hole 282. The rotating mounting block 28 is connected to the lifting transverse movement mechanism 722, so that under the action of the lifting transverse movement mechanism 722, the lifting wheel 723 and the lifting hook 724 move along the lifting transverse movement guide post 727 in the Y direction to adapt to the lifting operation in curves and turnout areas.

[0078] The lifting wheel 723 and the lifting hook 724 are connected to each other and can rotate under the action of the lifting switching mechanism 725, thereby realizing the operation using the lifting wheel 723 or the operation using the lifting hook 724. The lifting hook movement mechanism 726 is used to move the lifting hook 724 to realize the hooking action of the lifting hook 724 on the head and bottom of the rail. The lining device 73 includes a lining drive mechanism 731 and a lining wheel 732.

[0079] At the fishplate of the rail, the track lifting hook 724 is used for operation, and at other positions, the track lifting wheel 723 is preferably used for operation. One end of the track lifting switching mechanism 725 is connected to the lifting and lining frame 71, and the other end is connected to the track lifting wheel 723 and the track lifting hook 724.

[0080] As Figure 3 , Figure 4 shown, one end of the track lifting switching mechanism 725 is connected to the bracket of the lifting and lining frame 71, and the other end of the track lifting switching mechanism 725 is connected to the rotating mounting block 728. The track lifting switching mechanism 725 is a telescopic rod, an oil cylinder or a cylinder. When the track lifting switching mechanism 725 extends, the rotating mounting block 728 rotates downward along the axis of the track lifting transverse guide post 727, driving the track lifting wheel 723 and the track lifting hook 724 to rotate clockwise, making the installation axis of the track lifting wheel 723 parallel to the Z direction and the installation axis of the track lifting hook 724 in the X direction, thereby realizing the operation with the track lifting wheel 723; when the track lifting switching mechanism 725 shortens, the rotating mounting block 728 rotates upward along the axis of the track lifting transverse guide post 727, driving the track lifting wheel 723 and the track lifting hook 724 to rotate counterclockwise, making the installation axis of the track lifting wheel 723 parallel to the X direction and the installation axis of the track lifting hook 724 parallel to the Z direction, thereby enabling the operation with the track lifting hook 24.

[0081] The track lifting hook 724 is connected to the track lifting hook moving mechanism 726 above. One end of the track lifting hook moving mechanism 726 is fixedly installed on the rotating mounting block 728, and the other end is connected to the track lifting hook 724, so that the track lifting hook moving mechanism 726 drives the track lifting hook 724 to move along the Z direction, realizing the hooking action of the track lifting hook 724 on the rail head and the rail bottom.

[0082] The lining device 73 includes a lining driving mechanism 731 and a lining wheel 732; one end of the lining driving mechanism 731 is connected to the body of the track maintenance machine, and the other end is connected to the lifting and lining frame 71. The axis of the lining driving mechanism 731 connected to the lifting and lining frame 71 is arranged in the X direction. Thus, when the pulling force or pushing force of the lining driving mechanism 731 acts on the lifting and lining frame 71, the lifting and lining frame 71 moves along the Y direction relative to the body of the track maintenance machine. The lining wheels 732 are placed on the outer sides of the two ends of the lifting and lining frame 71 in the X direction. The lining wheels 732 adopt a structure with a rib on one side of the wheel rim, enabling them to run along the rail. Under the action of the lining driving mechanism 731, the lifting and lining frame 71 moves along the Y direction, and then drives the lining wheels 732 to move along the Y direction, realizing the lining operation.

The clamping and opening drive device 82 is connected to the clamping device 84 through a joint 83. The joint 83 has two kinematic pairs, namely, the rotation axis is perpendicular to the movement plane of the clamping device 84 and the rotation axis is parallel to the movement plane of the clamping device 84, and is used to transmit the effective direction vibration generated by the vibration excitation device 81 and eliminate the ineffective direction vibration. The tamping device 8 further includes a box body 85 and guide columns 86 for support and operation guidance.

The rotary drive device 914 drives the rotary beam 912 to rotate relative to the fixed beam 911 with the rotary shaft 913 as the center. At the same time, the rotary beam 912 is also connected to the rotary cavity 932, so as to transmit the rotary motion of the rotary beam 912 to the rotary cavity 932.

[0085] The transverse movement device 92 includes a first transverse movement beam 921, a second transverse movement beam 922, a movable fulcrum 923, an end plate 924, a fulcrum guide post 925, a transverse movement drive device 926, and a fulcrum drive mechanism 927. The first transverse movement beam 921 is installed inside the rotary cavity 932. The transverse movement drive device 926 is connected between the first transverse movement beam 921 and the rotary cavity 932, and when the transverse movement drive device 926 acts, the first transverse movement beam 921 generates a transverse movement relative to the rotary cavity 932. One end of the second transverse movement beam 922 is connected to the end of the first transverse movement beam 921 through the end plate 924. A movable fulcrum 923 is installed at the other end of the second transverse movement beam 922. At the same time, the movable fulcrum 923 is nested on the fulcrum guide post 925, so that the second transverse movement beam 922 can move along the fulcrum guide post 925. The fulcrum guide post 925 is installed outside the rotary cavity 932. This structure enables the fulcrum of the second transverse movement beam 922 to change with the change of the transverse movement position, thereby making the transverse movement range wider.

[0086] The operation unit mounting frame 94 is installed on the second transverse movement beam 922. The operation unit mounting frame 94 includes an operation unit transverse movement guide sleeve 941 and an operation unit transverse movement drive mechanism 942. The operation unit transverse movement drive mechanism 942 is connected between the operation unit mounting frame 94 and the rotary cavity 921, and enables the operation unit mounting frame 94 to move transversely along the second transverse movement beam 922. The mounting fulcrum drive mechanism 927 is connected between the rotary cavity 921 and the movable fulcrum 923, so that the movable fulcrum 923 moves along the fulcrum guide post 925, realizing the active adjustment of the position of the movable fulcrum 923.

[0087] Embodiment 2.1: A tamping car applicable to turnout operation is the same as Embodiment 1.1, except for the structure of the rotary transverse movement frame as Figure 7 - Figure 9 shown. Among them Figure 8 is the internal frame structure diagram, Figure 9 is the external frame structure diagram.

[0088] As Figure 7 shown, the rotary transverse movement frame 9a includes an internal rotary transverse movement device 91a, an external rotary transverse movement device 92a, and an operation unit mounting frame 93a.

[0089] The internal rotary transverse movement device 91a includes an internal rotary device 911a and an internal transverse movement device 912a, which are respectively used to realize the rotary movement and the transverse movement. As Figure 8As shown in the figure, the inner rotation device 911a includes an inner fixed beam 9111a, an inner rotation beam 9112a, an inner rotation shaft 9113a, an inner fixed frame 9114a, an inner rotation frame 9115a, and an inner rotation drive mechanism 9116a. Both the inner fixed beam 9111a and the inner fixed frame 9114a are fixed to the body of the road maintenance machine. The inner rotation beam 9112a is fixedly connected to the inner rotation frame 9115a. The inner fixed beam 9111a is connected to the inner rotation beam 9112a through the inner rotation shaft 9113a. One end of the inner rotation drive mechanism 116 is connected to the inner rotation beam 112, and the other end of the inner rotation drive mechanism 116 is connected to the inner fixed frame 114. When the inner rotation drive mechanism 9116a acts, the inner rotation beam 9112a will drive the inner rotation frame 9115a to rotate around the inner rotation shaft 9113a, thereby realizing the rotation action.

[0090] The inner transverse movement device 912a includes an inner transverse movement guide post 9121a, an inner transverse movement guide sleeve 9122a, and an inner transverse movement drive mechanism 9123a. An inner operation unit mounting frame 931a is installed on the inner transverse movement guide sleeve 9122a and can slide along the inner transverse movement guide post 9121a under the action of the inner transverse movement drive mechanism 9123a. The inner transverse movement guide post 9121a is connected to the inner rotation frame 9115a. Therefore, when the inner rotation frame 9115a rotates, the inner transverse movement guide post 9121a also rotates, thereby driving the inner operation unit mounting frame 931a to rotate. One end of the inner transverse movement drive mechanism 9123a is connected to the inner operation unit mounting frame 931a, and the other end is connected to the inner fixed frame 9114a. When the inner transverse movement drive mechanism 9123a acts, it drives the inner operation unit mounting frame 931a to move along the inner transverse movement guide post 9121a, thereby realizing the transverse movement action. In this embodiment, two sets of inner operation unit mounting frames 931a are installed for inner side operations.

[0091] In this embodiment, the inner fixed frame 9114a includes an inner fixed frame guide groove. Preferably, the inner fixed frame guide groove is arranged at the edge of the inner fixed frame 9114a, or more preferably, the inner fixed frame guide groove is evenly arranged at the four corners of the edge of the inner fixed frame 9114a.

[0092] The end of the inner rotation frame 9115a is connected to the end of the inner transverse movement guide post 9121a, and the connection point after the connection of the end of the inner rotation frame 9115a and the end of the inner transverse movement guide post 9121a is further lapped in the fixed frame guide groove. When the inner rotation drive mechanism 916a acts, it drives the inner rotation beam 9112a to rotate, driving the inner rotation frame 9115a to rotate, thereby driving the inner transverse movement guide post 9121a to rotate, and then driving the inner transverse movement guide sleeve 9122a and the inner operation unit mounting frame 931a to rotate, so as to realize the transmission of the rotation action.

[0093] Since the inner rotation frame 9115a and the inner transverse guide post 9121a are lapped in the inner fixed frame guide groove, the gravity generated by components such as the operation unit, the inner operation unit mounting frame 931a, the inner rotation frame 9115a, and the inner transverse guide post 9121a will be mainly transmitted directly to the inner fixed frame 9114a through the inner fixed frame guide groove, and then transmitted to the maintenance machinery vehicle body, avoiding the gravity acting on the inner rotation shaft 9113a, improving the force bearing of the entire rotation frame, and enhancing the reliability and service life.

[0094] The inner transverse guide post 9121a is also connected to the inner rotation frame 9115a. Therefore, when the inner rotation frame 9115a rotates, the inner transverse guide post 9121a also rotates, thereby driving the inner operation unit mounting frame 931a to rotate. Therefore, under the simultaneous action of the inner rotation drive mechanism 9116a and the inner transverse drive mechanism 9123a, the inner operation unit mounting frame 931a can generate a rotational transverse movement. The inner operation unit mounting frame 931a is used to mount the operation unit, and then realizes the rotational transverse movement of the operation unit.

[0095] As Figure 9 shown, the outer rotation and transverse movement device 92a includes an outer rotation device 921a and an outer transverse movement device 922a, which are respectively used to realize the rotation action and the transverse movement action. The outer rotation device 921a includes a first outer rotation shaft 9211a, a first outer rotation drive mechanism 9212a, a second outer rotation shaft 9213a, and a second outer rotation drive mechanism 9214a. The outer transverse movement device 922a includes an outer telescopic arm 9221a and an outer transverse drive mechanism 9222a. One end of the outer telescopic arm 9221a is hinged to the tamping car vehicle body through the first outer rotation shaft 9211a, and the other end is hinged to the outer operation unit mounting frame 932a through the second outer rotation shaft 9213a. The outer telescopic arm 9221a is composed of a multi-layer guide sleeve structure, and under the action of the outer transverse drive mechanism 9222a, it undergoes telescopic changes to realize the transverse movement action.

[0096] One end of the outer telescopic arm 9221a is hinged to the maintenance machinery vehicle body through the first outer rotation shaft 9211a, and the other end of the outer telescopic arm 9221a is hinged to the outer operation unit mounting frame 932a through the second outer rotation shaft 9213a; the outer telescopic arm 9221a rotates around the first outer rotation shaft 9211a under the action of the first outer rotation drive mechanism 9212a to realize the rotation action. When the second outer rotation drive mechanism 9214a acts, it drives the outer operation unit mounting frame 932a to rotate around the second outer rotation shaft 9213a to realize a further rotation action.

[0097] When the outer lateral translation drive mechanism 9222a acts, the outer telescopic arm 9221a undergoes telescopic changes, thereby driving the outer operation unit mounting bracket 932a to perform a lateral translation action. When the first outer rotation drive mechanism 9212a acts, it drives the outer telescopic arm 9221a to rotate around the first outer rotation axis 9211a, thereby driving the outer operation unit mounting bracket 932a to perform a rotation action. When the second outer rotation drive mechanism 9214a acts, it drives the outer operation unit mounting bracket 932a to rotate around the second outer rotation axis 9213a, achieving a further rotation action.

[0098] Due to the existence of two rotation points, namely the first outer rotation axis 9211a and the second outer rotation axis 9213a, on the outer rotation device 921a, the rotation action is more flexible. Under the combined action of the first outer rotation drive mechanism 9212a, the second outer rotation drive mechanism 9214a, and the outer lateral translation drive mechanism 9222a, the outer operation unit mounting bracket 932a can perform a rotation and lateral translation action. The outer operation unit mounting bracket 932a is used to mount the operation unit, thereby realizing the rotation and lateral translation action of the operation unit.

[0099] In this embodiment, preferably two sets of outer operation unit mounting brackets 932a are installed for outer operations. The outer telescopic arm 9221a preferably adopts a three-stage guide sleeve structure. The more stages are used, the farther the outer end of the outer telescopic arm can reach.

[0100] In this embodiment, preferably, an inner and outer operation unit mounting bracket locking mechanism 94a is installed between the inner operation unit mounting bracket 931a and the outer operation unit mounting bracket 932a, and the inner operation unit mounting bracket 931a and the outer operation unit mounting bracket 932a are connected or unlocked through the inner and outer operation unit mounting bracket locking mechanism 94a. When the operation unit does not need to perform remote operations, the inner operation unit mounting bracket 931a and the outer operation unit mounting bracket 932a can be fixedly connected to each other and controlled to act uniformly by the inner rotation and lateral translation device 91a. When the operation unit needs to perform remote operations, the inner operation unit mounting bracket 931a and the outer operation unit mounting bracket 932a are unlocked from each other. The inner operation unit mounting bracket 931a is controlled to act by the inner rotation and lateral translation device 91a, and the outer operation unit mounting bracket 932a is controlled to act by the outer rotation and lateral translation device 92a. The inner operation unit mounting bracket 931a and the outer operation unit mounting bracket 932a operate independently without interference.
