[0001] The present application relates to the technical field of railway maintenance machinery, and specifically, to a three-sleeper tamping device. Background Art

[0002] Tamping operation is one of the main tasks for maintaining the ballast bed of ballasted railways. Through tamping, the stability of the railway ballast bed can be effectively improved, ensuring the safety of train operation. In order to improve the tamping operation efficiency and at the same time ensure that the tamping device can adapt to railway ballast beds with different sleeper spacings, currently during the main line tamping operation, the maximum number of sleepers that can be tamped simultaneously at one time is three, that is, a three-sleeper tamping device is used for operation. The widely used three-sleeper tamping device currently adopts the eccentric shaft connecting rod swinging vibration principle, where each tamping arm is connected to the eccentric shaft, and the vibration excitation generated by the eccentric shaft is transmitted to the tamper.

[0003] In order to achieve three-sleeper tamping, multiple eccentric shafts and multiple clamping cylinders are usually adopted, resulting in problems such as complex structure, large number of components, and high manufacturing cost for the three-sleeper tamping device. Summary of the Invention

[0009] A tamper is installed at the bottom end of the tamping arm, and the middle part is hinged to the frame through a fixed hinge point and can rotate around the hinge point with the frame.

[0010] Adopting the three-sleeper tamping device provided in the embodiments of the present application has the following beneficial effects:

[0011] In the above three-sleeper tamping device, the excitation device generates vibration, the opening and closing drive device generates opening and closing control to produce a clamping action on the tamping arm, the vibration generated by the excitation device is transmitted to the tamping arm through the opening and closing drive device, and the vibration is transmitted and the clamping control is carried out between the tamping arms through the tamping arm transmission device, so as to transmit the vibration to the tamper at the bottom end of the tamping arm; since the above three-sleeper tamping device can complete the vibration transmission and the clamping action through fewer excitation devices, opening and closing drive devices, tamping arms and tamping arm transmission devices, therefore, the above three-sleeper tamping device has the advantages of simple structure, small number of parts and low manufacturing cost.

[0029] The tamping arm transmission device is hinged between the tamping arms; as Figure 1 As shown in the structure, a tamping arm transmission device is hinged between the first primary tamping arm 7 and the first secondary tamping arm 11, and between the second secondary tamping arm 12 and the fourth primary tamping arm 10. The vibration generated by the excitation device 2 and the opening and closing control generated by the opening and closing drive device are transmitted to the first secondary tamping arm 11 through the first primary tamping arm 7 by the tamping arm transmission device, and are transmitted to the second secondary tamping arm 12 through the fourth primary tamping arm 10; as Figure 2 As shown in the structure, tamping arm transmission devices for transmitting vibration and opening and closing control are provided between the first primary tamping arm 7 and the first secondary tamping arm 11, between the first secondary tamping arm 11 and the first tertiary tamping arm 13, between the second primary tamping arm 8 and the second secondary tamping arm 12, and between the second secondary tamping arm 12 and the second tertiary tamping arm 14; for the convenience of description and distinction, each tamping arm transmission device can be defined as the first tamping arm transmission device 16, the second tamping arm transmission device 17, the third tamping arm transmission device 18, and the fourth tamping arm transmission device 19; the tamping arm transmission device can be a connecting rod, and the length of the connecting rod is fixed or adjustable;

Preferably, the tamping arms are all arranged in the vertical direction, with a tamping pick installed at the bottom end, and the middle part is hinged to the frame 1 through a fixed hinge point 15 and can rotate around the hinge point with the frame 1; according to the different vibration transmission paths of the tamping arms, the tamping arms can be divided into two-stage tamping arms and three-stage tamping arms; as Figure 1 As shown in the structure, the tamping arms include the first primary tamping arm 7, the second primary tamping arm 8, the third primary tamping arm 9, the fourth primary tamping arm 10, the first secondary tamping arm 11, and the second secondary tamping arm 12; as Figure 2 As shown in the structure, the tamping arms include the first primary tamping arm 7, the second primary tamping arm 8, the first secondary tamping arm 11, the second secondary tamping arm 12, the first tertiary tamping arm 13, and the second tertiary tamping arm 14.

[0031] Meanwhile, for the convenience of description, Figures 1-9 also shows three sleepers, namely the first sleeper 28, the second sleeper 29, and the third sleeper 30.

[0032] The working principle of the above three-sleeper tamping device is as follows: The excitation device 2 generates vibrations, and the vibrations are transmitted to each tamping arm through the opening and closing drive device, causing the tampers installed on each tamping arm to vibrate; the tamping arm can include a primary tamping arm and a secondary tamping arm, and can also include a primary tamping arm, a secondary tamping arm, and a tertiary tamping arm; the opening and closing drive device transmits the vibrations generated by the excitation device 2 to the primary tamping arm, and the primary tamping arm transmits the vibrations to the secondary tamping arm through the tamping arm transmission device, and the secondary tamping arm transmits the vibrations to the tertiary tamping arm through the tamping arm transmission device, causing the tampers installed on the primary tamping arm, secondary tamping arm, and tertiary tamping arm to vibrate. Using the above vibration transmission method can enable all tampers to obtain vibrations, which is beneficial to the insertion of the tampers during tamping; meanwhile, by driving the primary tamping arm to rotate through the opening and closing drive device, the tamper installed on the primary tamping arm generates a clamping action, and the rotational movement of the primary tamping arm is transmitted to the secondary tamping arm and the tertiary tamping arm through the tamping arm transmission device, enabling the secondary tamping arm and the tertiary tamping arm to both generate clamping actions, thereby realizing the clamping actions of all tampers, and realizing the relative clamping actions of the tampers through the cooperation of each tamping arm.

[0033] In the above three-sleeper tamping device, the excitation device 2 generates vibrations, the opening and closing drive device generates opening and closing to control the tamping arm to generate a clamping action, and the vibrations generated by the excitation device 2 are transmitted to the tamping arm through the opening and closing drive device. The tamping arms transmit vibrations and clamping control to each other through the tamping arm transmission device, thereby transmitting the vibrations to the tampers at the bottom end of the tamping arm; since the three-sleeper tamping device can complete vibration transmission and clamping actions with a relatively small number of excitation devices 2, opening and closing drive devices, tamping arms, and tamping arm transmission devices, therefore, the above three-sleeper tamping device has the advantages of simple structure, few components, and low manufacturing cost.

[0034] The above three-sleeper tamping device can be divided into the following specific embodiments for detailed description according to different specific structures adopted:

[0035] Embodiment 1

[0036] As Figure 1As shown in the structure, the excitation device 2 includes a first excitation device 20 and a second excitation device 21 which are symmetrically arranged; the opening and closing driving device includes a first outer opening and closing driving device 3 and a second outer opening and closing driving device 4 which are symmetrically arranged, and a first inner opening and closing driving device 5 and a second inner opening and closing driving device 6 which are symmetrically arranged; the tamping arm transmission device includes a first tamping arm transmission device 16 and a second tamping arm transmission device 17 which are symmetrically arranged; the tamping arm includes a first primary tamping arm 7, a second primary tamping arm 8, a third primary tamping arm 9, a fourth primary tamping arm 10, a first secondary tamping arm 11 and a second secondary tamping arm 12; both the first outer opening and closing driving device 3 and the second outer opening and closing driving device 4 are arranged in the horizontal direction; one end of the first outer opening and closing driving device 3 is connected to the first excitation device 20, and the other end is hinged to the first primary tamping arm 7; one end of the second outer opening and closing driving device 4 is connected to the second excitation device 21, and the other end is hinged to the fourth primary tamping arm 10; both the first inner opening and closing driving device 5 and the second inner opening and closing driving device 6 are arranged obliquely in the vertical direction; one end (such as the top end shown in Figure 1 ) of the first inner opening and closing driving device 5 is connected to the first excitation device 20 (such as the bottom end shown in Figure 1 ), and the other end is hinged to the second primary tamping arm 8; one end (such as the top end shown in Figure 1 ) of the second inner opening and closing driving device 6 is connected to the second excitation device 21 (such as the bottom end shown in Figure 1 ), and the other end is hinged to the third primary tamping arm 9; a first secondary tamping arm 11 is arranged between the first primary tamping arm 7 and the second primary tamping arm 8, the top end of the first secondary tamping arm 11 is hinged to the first primary tamping arm 7 through the first tamping arm transmission device 16, and the movable hinge point of the first tamping arm transmission device 16 and the first primary tamping arm 7 is located between the fixed hinge point 15 and the first outer opening and closing driving device 3; a second secondary tamping arm 12 is arranged between the third primary tamping arm 9 and the fourth primary tamping arm 10, the top end of the second secondary tamping arm 12 is hinged to the fourth primary tamping arm 10 through the second tamping arm transmission device 17, and the movable hinge point of the second tamping arm transmission device 17 and the fourth primary tamping arm 10 is located between the fixed hinge point 15 and the second outer opening and closing driving device 4.

[0037] During the operation of the above three-sleeper tamping device, when the first outer opening and closing drive device 3, the second outer opening and closing drive device 4, the first inner opening and closing drive device 5, and the second inner opening and closing drive device 6 open, the first tamper 22 and the third tamper 24 clamp towards the first sleeper 28, the second tamper 23 and the fifth tamper 26 clamp towards the second sleeper 29, and the fourth tamper 25 and the sixth tamper 27 clamp towards the third sleeper 30. At this time, the tamper shoes of the first tamper 22 and the third tamper 24 are arranged facing each other to realize tamping of the first sleeper 28, the tamper shoes of the second tamper 23 and the fifth tamper 26 are arranged facing each other to realize tamping of the second sleeper 29, and the tamper shoes of the fourth tamper 25 and the sixth tamper 27 are arranged facing each other to realize tamping of the third sleeper 30. Therefore, with the three-sleeper tamping device having the above structure, tamping operations can be carried out on three sleepers simultaneously.

[0038] As Figure 6 shown in the structure, the first excitation device 20, the first inner opening and closing drive device 5, and the first outer opening and closing drive device 3 are of an integral structure and form the first excitation type opening and closing drive device 32; the second excitation device 21, the second inner opening and closing drive device 6, and the second outer opening and closing drive device 4 are of an integral structure and form the second excitation type opening and closing drive device 33.

[0039] Since the first excitation type opening and closing drive device 32 is used to replace the first excitation device 20, the first inner opening and closing drive device 5, and the first outer opening and closing drive device 3, and the second excitation type opening and closing drive device 33 is used to replace the second excitation device 21, the second inner opening and closing drive device 6, and the second outer opening and closing drive device 4, the structure of the three-sleeper tamping device is made simpler.

[0040] Embodiment 2

[0041] As Figure 2As shown in the structure, the excitation device 2 includes a first excitation device 20 and a second excitation device 21 which are symmetrically arranged; the opening and closing drive device includes a first outer opening and closing drive device 3 and a second outer opening and closing drive device 4 which are symmetrically arranged; the tamping arm transmission device includes a first tamping arm transmission device 16 and a second tamping arm transmission device 17 which are symmetrically arranged, and a third tamping arm transmission device 18 and a fourth tamping arm transmission device 19 which are symmetrically arranged; the tamping arms include a first primary tamping arm 7, a second primary tamping arm 8, a first secondary tamping arm 11, a second secondary tamping arm 12, a first tertiary tamping arm 13 and a second tertiary tamping arm 14; the first outer opening and closing drive device 3 and the second outer opening and closing drive device 4 are both arranged in the horizontal direction; one end of the first outer opening and closing drive device 3 is connected to the first excitation device 20, and the other end is hinged to the first primary tamping arm 7; one end of the second outer opening and closing drive device 4 is connected to the second excitation device 21, and the other end is hinged to the second primary tamping arm 8; on the side of the first primary tamping arm 7 facing the second primary tamping arm 8, a first secondary tamping arm 11, a first tertiary tamping arm 13, a second tertiary tamping arm 14 and a second secondary tamping arm 12 are arranged in sequence; the top end of the first secondary tamping arm 11 is hinged to the first primary tamping arm 7 through the first tamping arm transmission device 16, and the top end of the second secondary tamping arm 12 is hinged to the second primary tamping arm 8 through the second tamping arm transmission device 17; the top end of the first tertiary tamping arm 13 is hinged to the first secondary tamping arm 11 through the third tamping arm transmission device 18, and the top end of the second tertiary tamping arm 14 is hinged to the second secondary tamping arm 12 through the fourth tamping arm transmission device 19.

[0042] During the working process of the above three-sleeper tamping device, when the first outer opening and closing drive device 3 and the second outer opening and closing drive device 4 open, the first tamper 22 and the third tamper 24 clamp towards the first sleeper 28, the second tamper 23 and the fifth tamper 26 clamp towards the second sleeper 29, and the fourth tamper 25 and the sixth tamper 27 clamp towards the third sleeper 30. At this time, the tamper shoes of the first tamper 22 and the third tamper 24 are arranged facing each other to tamp the first sleeper 28, the tamper shoes of the second tamper 23 and the fifth tamper 26 are arranged facing each other to tamp the second sleeper 29, and the tamper shoes of the fourth tamper 25 and the sixth tamper 27 are arranged facing each other to tamp the third sleeper 30. Therefore, it is possible to perform tamping operations on three sleepers simultaneously.

[0043] As Figure 7 As shown in the structure, the first excitation device 20 and the first outer opening and closing drive device 3 are an integral structure and form a first excitation type opening and closing drive device 32; the second excitation device 21 and the second outer opening and closing drive device 4 are an integral structure and form a second excitation type opening and closing drive device 33.

[0044] Since the first excitation type opening and closing drive device 32 is adopted to replace the first excitation device 20 and the first outer opening and closing drive device 3, and the second excitation type opening and closing drive device 33 is adopted to replace the second excitation device 21 and the second outer opening and closing drive device 4, the structure of the three-sleeper tamping device is made simpler.

[0045] Embodiment 3

[0046] As Figure 3 As shown in the structure, the three-sleeper tamping device includes one said excitation device; the opening and closing drive devices include the first outer opening and closing drive device 3 and the second outer opening and closing drive device 4 which are symmetrically arranged; the tamping arm transmission devices include the first tamping arm transmission device 16 and the second tamping arm transmission device 17 which are symmetrically arranged, and the third tamping arm transmission device 18 and the fourth tamping arm transmission device 19 which are symmetrically arranged; the tamping arms include the first primary tamping arm 7, the second primary tamping arm 8, the first secondary tamping arm 11, the second secondary tamping arm 12, the first tertiary tamping arm 13 and the second tertiary tamping arm 14; both the first outer opening and closing drive device 3 and the second outer opening and closing drive device 4 are arranged in the horizontal direction; one end of the first outer opening and closing drive device 3 is connected to the excitation device 2, and the other end is hinged to the first primary tamping arm 7; one end of the second outer opening and closing drive device 4 is connected to the excitation device 2, and the other end is hinged to the second primary tamping arm 8; on the side of the first primary tamping arm 7 facing the second primary tamping arm 8, the first secondary tamping arm 11, the first tertiary tamping arm 13, the second tertiary tamping arm 14 and the second secondary tamping arm 12 are arranged in sequence; the top end of the first secondary tamping arm 11 is hinged to the first primary tamping arm 7 through the first tamping arm transmission device 16, and the top end of the second secondary tamping arm 12 is hinged to the second primary tamping arm 8 through the second tamping arm transmission device 17; the top end of the first tertiary tamping arm 13 is hinged to the first secondary tamping arm 11 through the third tamping arm transmission device 18, and the top end of the second tertiary tamping arm 14 is hinged to the second secondary tamping arm 12 through the fourth tamping arm transmission device 19.

[0047] Since the above three-sleeper tamping device only adopts one excitation device 2, the structure of the three-sleeper tamping device is simplified. At the same time, the first outer opening and closing drive device 3 and the second outer opening and closing drive device 4 are symmetrically arranged on both sides of the excitation device 2, so that the forces on the excitation device 2 can cancel each other out, which is beneficial to extending the service life of the excitation device 2, and thus extending the service life of the three-sleeper tamping device.

[0048] As Figure 8 As shown in the structure, the excitation device 2, the first outer opening and closing drive device 3 and the second outer opening and closing drive device 4 are of an integral structure and form an excitation type opening and closing drive device 31.

[0049] Since the vibration excitation type opening and closing drive device 31 is adopted to replace the vibration excitation device 2, the first outer side opening and closing drive device 3, and the second outer side opening and closing drive device 4, the structure of the three-pillow tamping device is further simplified.

[0050] Embodiment 4

[0051] As Figure 4 shown in the structure, the vibration excitation device 2 includes a first vibration excitation device 20 and a second vibration excitation device 21 distributed in the vertical direction, and the first vibration excitation device 20 is located at the top of the second vibration excitation device 21; the opening and closing drive device includes a symmetrically arranged first inner side opening and closing drive device 5 and a second inner side opening and closing drive device 6, and a symmetrically arranged first outer side opening and closing drive device 3 and a second outer side opening and closing drive device 4; the tamping arm transmission device includes a symmetrically arranged first tamping arm transmission device 16 and a second tamping arm transmission device 17; the tamping arms include a first primary tamping arm 7, a second primary tamping arm 8, a third primary tamping arm 9, a fourth primary tamping arm 10, a first secondary tamping arm 11, and a second secondary tamping arm 12; the first outer side opening and closing drive device 3 and the second outer side opening and closing drive device 4 are both arranged in the horizontal direction and are connected to the first vibration excitation device 20; one end of the first outer side opening and closing drive device 3 far from the first vibration excitation device 20 is hinged to the first primary tamping arm 7; one end of the second outer side opening and closing drive device 4 far from the first vibration excitation device 20 is hinged to the fourth primary tamping arm 10; the first vibration excitation device 20 is located between the first outer side opening and closing drive device 3 and the second outer side opening and closing drive device 4; the first inner side opening and closing drive device 5 and the second inner side opening and closing drive device 6 are both arranged obliquely in the vertical direction; one end (such as Figure 4 the top shown) of the first inner side opening and closing drive device 5 is connected to the second vibration excitation device 21 (such as Figure 4 the bottom shown), and the other end is hinged to the second primary tamping arm 8; one end (such as Figure 4 the top shown) of the second inner side opening and closing drive device 6 is connected to the second vibration excitation device 21 (such as Figure 4 the bottom shown), and the other end is hinged to the third primary tamping arm 9; a first secondary tamping arm 11 is arranged between the first primary tamping arm 7 and the second primary tamping arm 8, and the top of the first secondary tamping arm 11 is hinged to the first primary tamping arm 7 through the first tamping arm transmission device 16, and the movable hinge point of the first tamping arm transmission device 16 and the first primary tamping arm 7 is located between the fixed hinge point 15 and the first outer side opening and closing drive device 3; a second secondary tamping arm 12 is arranged between the third primary tamping arm 9 and the fourth primary tamping arm 10, and the top of the second secondary tamping arm 12 is hinged to the fourth primary tamping arm 10 through the second tamping arm transmission device 17, and the movable hinge point of the second tamping arm transmission device 17 and the fourth primary tamping arm 10 is located between the fixed hinge point 15 and the second outer side opening and closing drive device 4.

[0052] The first excitation device 20 and the second excitation device 21 of the above three-sleeper tamping device are arranged in an up-and-down structure. When the third tamper 24 and the fourth tamper 25 perform the clamping action, the first inner opening and closing driving device 5 and the second inner opening and closing driving device 6 need to perform a contraction action. When the third tamper 24 and the fourth tamper 25 perform the opening action, the first inner opening and closing driving device 5 and the second inner opening and closing driving device 6 need to perform an elongation action.

[0053] As Figure 9 shown in the structure, the first excitation device 20, the first outer opening and closing driving device 3, and the second outer opening and closing driving device 4 are of an integral structure and constitute the first excitation type opening and closing driving device 32; the second excitation device 21, the first inner opening and closing driving device 5, and the second inner opening and closing driving device 6 are of an integral structure and constitute the second excitation type opening and closing driving device 33.
