[0033] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0034] Embodiment 1

[0035] Figure 1 This is a schematic diagram of a tamping assembly according to an embodiment of the present application.

[0036] As shown in the figure, the tamping assembly of the embodiment of the present application includes:

[0037] two tamping modules 1;

[0038] A connecting frame 2, wherein two tamping modules 1 are respectively connected at both ends of the connecting frame 2 in the transverse direction, and the two tamping modules 1 are spaced apart in the transverse direction of the connecting frame;

[0039] The connecting frame 2 is used to be fixed to the frame of the tamping device and to span across the two sides of the rail to be tamped. The two tamping modules 1 are used to tamping the ballast on both sides of the rail 51 .

[0040] In the tamping assembly of the embodiment of the present application, two tamping modules are connected by a connecting frame. The two tamping modules share the connecting frame, which also provides a basis for the two tamping modules to share other parts. The connecting frame is also used to fix with the frame of the tamping device. At the same time, since the two tamping modules are respectively connected to the two ends of the connecting frame in the lateral direction, and the two tamping modules are spaced apart in the lateral direction of the connecting frame. In this way, when the connecting frame spans across the two sides of the rail to be tamped, the two tamping modules can tamp the ballast on both sides of the rail. The tamping assembly of the embodiment of the present application has a simple structure, realizes the connection of the two tamping modules, and provides a basis for the two tamping modules to share other parts. The tamping assembly has a small number of parts and has low manufacturing and maintenance costs. At the same time, when the two tamping modules of the same tamping assembly tamp the ballast on both sides of the rail, the distance of the two tamping modules of the same tamping assembly from the rail is limited by the connecting frame.

[0041] During implementation, the tamping component also includes:

[0042] The vibration device 3 is connected to the connecting frame 2, and the vibration device 3 is used to provide the vibration required for tamping for the two tamping modules of the same tamping assembly.

[0043] The vibrating device is connected to the connecting frame to provide the vibration required for tamping for the two tamping modules of the same tamping assembly. In this way, the two tamping modules share the vibrating device, so that the tamping assembly has fewer parts and a simple structure.

[0044] Embodiment 2

[0045] The tamping assembly of the embodiment of the present application, based on the first embodiment, also has the following characteristics.

[0046] In implementation, such as Figure 1 and Figure 3 As shown, the two tamping modules 1 are arranged diagonally at both ends of the connecting frame 2 in the transverse direction;

[0047] The two tamping modules 1 are used to tamp the ballast at the diagonal position in the cross-shaped position formed by the intersection of the rail 51 and the sleeper 52.

[0048] There are many ways to realize that the two tamping modules are arranged diagonally at both ends of the connecting frame in the transverse direction, which are described below with reference to the accompanying drawings.

[0049] As an alternative, Figure 2 As shown, the connecting frame 2 includes:

[0050] A connecting rod 21, used to connect with the frame of the tamping device;

[0051] Two tamping module mounting seats 22 are provided at both ends of the upper surface of the connecting rod 21;

[0052] Among them, one of the tamping modules 1 is correspondingly connected to one of the tamping module mounting seats 22 .

[0053] In this way, the tamping module is connected to the tamping module mounting seat, and the connection position is located on the connecting rod. The two tamping modules are arranged diagonally at both ends of the connecting frame in the transverse direction, so that during the tamping operation, the clamping reaction force of the tamping module can be offset and not transmitted to the vibration device, thereby reducing the force required to be provided by the tamping module, and further making the size of the vibration device smaller. Specifically, the connecting rod can rotate around the axis.

[0054] In implementation, such as Figure 2 As shown, the connecting frame 2 also includes:

[0055] A vibration device mounting seat 23 is provided at the lower surface of the connecting rod 21, and the vibration device 3 is connected to the vibration device mounting seat 23;

[0056] The vibration device mounting seat 23 and one of the tamping module mounting seats are arranged at the same end of the connecting frame.

[0057] The vibrating device is located below the connecting rod. In this way, the parts above and below the connecting rod are fully utilized.

[0058] As an optional method, the connecting frame includes:

[0059] A connecting rod, used for connecting with the frame of the tamping device;

[0060] Two tamping module mounting seats are arranged at both ends of the lower surface of the connecting rod;

[0061] Wherein, one of the tamping modules is correspondingly connected to one of the tamping module mounting seats.

[0062] In this way, the tamping module is connected to the tamping module mounting seat, and the connection position is located below the connecting rod. The two tamping modules are arranged diagonally at both ends of the connecting frame in the transverse direction, so that during the tamping operation, the clamping reaction force of the tamping module can be offset and not transmitted to the vibration device, thereby reducing the force required to be provided by the tamping module, and further making the size of the vibration device smaller.

[0063] In implementation, the connecting frame further includes:

[0064] A vibration device mounting seat, arranged on the upper surface of the connecting rod, and the vibration device is fixed on the vibration device mounting seat;

[0065] Wherein, the vibration device mounting seat and one of the tamping module mounting seats are arranged at the same end of the connecting frame.

[0066] The vibrating device is located on the connecting rod. In this way, the parts above and below the connecting rod are fully utilized.

[0067] The difference between the two optional methods in the embodiment of the present application is that the installation positions of the vibrating device and the opening and closing drive device are different. When the vibrating device is located on the connecting rod, this embodiment is conducive to the pipeline connection of the vibrating device. In practical applications, any method can be selected according to the specific space of the tamping device including the tamping assembly.

[0068] In implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the tamping module 1 comprises:

[0069] An opening and closing driving device 11 is hinged to the tamping module mounting seat 22, and the opening and closing driving device 11 can be extended and retracted;

[0070] A tamping arm 12, wherein one tamping arm 12 is hinged to one of the opening and closing driving devices 11, and a tamping arm hinge hole 121 is provided in the middle of each tamping arm 12 for being hinged to an external frame;

[0071] A tamping pick 13, wherein one tamping pick 13 is correspondingly fixed to the lower end of one of the tamping arms 12;

[0072] The opening and closing driving device 11 is used to drive the tamping arm 12 to rotate around the tamping arm hinge hole 121 by telescoping so that the two tamping picks 13 produce a clamping action.

[0073] In this way, the clamping action of the tamping pick is realized through a simple structure; and the tamping of the ballast is realized by combining with the vibration of the vibration device.

[0074] Specifically, Figure 2 As shown, the end of the connecting rod serves as a frame hinge point 211. The frame hinge point 211 is used to connect the connecting frame and the frame.

[0075] Specifically, Figure 2 As shown, the tamping module mounting seat 22 is an arm-shaped tamping module mounting seat, and the open end of the arm-shaped tamping module mounting seat 22 has a tamping module mounting seat hinge point 221. The tamping module mounting seat hinge point 221 is movably hinged with the opening and closing drive device 11.

[0076] Specifically, the tamping module mounting seat is a single-ear structure or a fork-type double-ear structure.

[0077] In this way, the tamping module mounting seats are spaced apart in a direction perpendicular to the transverse direction of the connecting frame.

[0078] Specifically, Figure 2 As shown, the vibration device mounting seat 23 has a vibration device mounting seat hinge point 231. The vibration device mounting seat hinge point 231 is connected to the vibration device.

[0079] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the opening and closing driving device 11 includes an oil cylinder or a gas cylinder with telescopic ends;

[0080] The vibration device includes a mechanical vibration device, a hydraulic vibration device, an electromagnetic vibration device, an electromagnetic vibration device, or an electro-hydraulic vibration device.

[0081] Specifically, the mechanical excitation device may adopt an eccentric excitation mode, and the eccentric rotation direction may adopt a horizontal arrangement or a vertical arrangement mode.

[0082] Embodiment 3

[0083] The tamping assembly of the embodiment of the present application, based on the first embodiment, also has the following characteristics.

[0084] In implementation, such as Figure 4 As shown, the two tamping modules 1 are arranged at two ends of the same side of the connecting frame;

[0085] The two tamping modules 1 are used to tamp the ballast located on both sides of the rail and on the same side of the sleeper in a cross-shaped position formed by the intersection of the rail and the sleeper.

[0086] In this way, the two tamping modules located on the same side of the sleeper can tamp the ballast on both sides of the rail.

[0087] As an optional manner, the connecting frame includes:

[0088] A connecting rod, used for connecting with an external rack;

[0089] Two tamping module mounting seats are arranged at both ends of the upper side surface of the connecting rod;

[0090] Wherein, one of the tamping modules is correspondingly connected to one of the tamping module mounting seats.

[0091] In this way, the two tamping modules are connected to the two ends of the upper side surface of the connecting rod.

[0092] In implementation, the connecting frame further includes:

[0093] A vibration device mounting seat, arranged at the lower surface of the connecting rod, and the vibration device is connected to the vibration device mounting seat;

[0094] Wherein, the vibration device mounting seat and the two tamping module mounting seats are oriented on the same side surface.

[0095] In this way, the two tamping modules and the vibrating device are connected to the same side or both sides of the connecting rod.

[0096] Embodiment 4

[0097] Figure 5 To include two Figure 1 A schematic diagram of a single sleeper guide rail arrangement of the tamping assembly shown, Figure 6 for Figure 5 A front schematic diagram of a single sleeper guide rail device is shown; Figure 7 for Figure 5 A side schematic diagram of a single-sleeper guide rail arrangement is shown.

[0098] like Figure 5 , Figure 6 and Figure 7 As shown, the single-sleeper tamping device of the embodiment of the present application comprises:

[0099] The two tamping assemblies described in the first embodiment; as an alternative, the two tamping assemblies described in the second embodiment and the two tamping assemblies described in the third embodiment may also be used;

[0100] A frame 41, wherein the two tamping assemblies are respectively connected to the frame 41 through the connecting rods 21;

[0101] The four tamping modules of the two tamping assemblies are used to tamp the ballast at four positions of the cross-shaped position formed by the intersection of the rails and the sleepers.

[0102] The single-sleeper tamping device of the embodiment of the present application realizes the tamping of ballast at four positions in the cross-shaped position formed by the intersection of the rail and the sleeper at the same time, and the tamping efficiency is high; at the same time, the number of parts of the single-sleeper tamping device is small, and the manufacturing and maintenance costs of the single-sleeper tamping device are low. The frame provides a fixed fulcrum for each part of the single-sleeper tamping device.

[0103] In implementation, such as Figure 5 , Figure 6 and Figure 7 As shown, the single-sleeper tamping device also includes:

[0104] The lifting and inserting device 42 is connected to the frame 41 and is used to drive the frame 41 and the tamping assembly to lift and insert, so that the single-sleeper tamping device can be inserted into and leave the ballast bed.

[0105] The existence of the lifting and inserting device enables the single-sleeper tamping device to be inserted into and leave the ballast bed.

[0106] In implementation, such as Figure 5 , Figure 6 and Figure 7 As shown, the single-sleeper tamping device also includes:

[0107] The lubrication system 43 is used to lubricate the relatively moving positions in the single-sleeper tamping device.

[0108] The lubrication system can lubricate the relatively moving positions in the single-sleeper tamping device, so that the friction state of the relatively moving positions of the entire single-sleeper tamping device can reduce friction resistance and alleviate wear.

[0109] The working principle of the single-sleeper tamping device in the embodiment of the present application is:

[0110] The vibration device generates vibration, which is transmitted to the opening and closing drive devices located on both sides of the rail through the connecting frame, and then transmitted to the tamping arm connected to the opening and closing drive device, so that the tamping pick installed on the tamping arm vibrates, which is conducive to the insertion of the tamping pick during tamping. In addition, the opening and closing drive device pushes the tamping arm to rotate around the hinge hole of the tamping arm, so that the tamping pick installed on the tamping arm produces a clamping action, and the tamping picks cooperate with each other to achieve tamping operation.
