In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The embodiment provides a tamping device for tamping a sleeper of a ballast track. The tamping device can be applied to small tamping equipment and tamping vehicles.
Fig. 1 is a schematic diagram of an implementation principle of a tamping device provided in an embodiment of the present application. As shown in fig. 1, the present embodiment provides a tamping apparatus, including: the device comprises an excitation mechanism 1, a vibration transmission mechanism 2, an opening and closing driving mechanism 3 and a tamping arm 4.
The vibration exciting mechanism 1 is used for exciting the tamping arm to generate vibration through self action. The excitation mechanism 1 may be a mechanical excitation mechanism, for example: the eccentric excitation mechanism is adopted, and particularly, a mode that the eccentric shaft rotates to generate vibration can be adopted. Alternatively, the excitation mechanism 1 may be a hydraulic excitation mechanism, an electromagnetic excitation mechanism, or an electrohydraulic excitation mechanism.
The vibration transmission mechanism 2 is connected between the excitation mechanism 1 and the opening and closing drive mechanism 3. One end of the opening and closing driving mechanism 3 is connected with the vibration transmission mechanism 2, and the other end is connected with the tamping arm 4. The vibration generated by the vibration exciting mechanism 1 is transmitted to the tamping arm 4 through the vibration transmission mechanism 2 and the opening and closing driving mechanism 3 in sequence, so that the tamping arm 4 is convenient to insert downwards during tamping operation. The end of the tamping arm 4 is connected with the tamping pick, and vibration is transmitted to the railway ballast through the tamping pick, so that the railway ballast is moved to the lower part of the sleeper and the aim of compacting is fulfilled.
The opening and closing driving mechanism 3 is of a telescopic structure, and the distance between two ends of the opening and closing driving mechanism is variable. In the operation process, the end part of the opening and closing driving mechanism 3 stretches and retracts to drive the tamping arm 4 to generate tightening action so as to promote the railway ballast to move towards the lower part of the sleeper. The opening/closing drive mechanism 3 may be an oil cylinder, an air cylinder, or another member, or may be a mechanism driven by an oil cylinder, an air cylinder, or the like as a drive force.
One end of the tamping arm 4 is hinged with the opening and closing driving mechanism 3, and the other end is connected with the tamping pickaxe.
The vibration transmission mechanism 2 is connected between the excitation mechanism 1 and the opening and closing drive mechanism 3, the excitation mechanism 1 and the opening and closing drive mechanism 3 are separated, and when the excitation mechanism 1 or the opening and closing drive mechanism 3 is damaged, only the damaged part needs to be replaced. When one part is damaged, the work of other parts is not influenced.
The working principle of the tamping device is as follows: the vibration exciting mechanism 1 generates vibration through rotation of the eccentric shaft, and the vibration is transmitted to the tamping arm 4 through the vibration transmission mechanism 2 and the opening and closing driving mechanism 3, so that the tamping pickaxe installed at the bottom end of the tamping arm 4 vibrates. Meanwhile, the opening and closing driving mechanism 3 pushes the tamping arm 4 to generate tightening and clamping actions.
The technical scheme provided by the embodiment adopts an excitation mechanism, a vibration transmission mechanism, an opening and closing driving mechanism and a tamping arm, wherein the vibration transmission mechanism is connected between the excitation mechanism and the opening and closing driving mechanism; one end of the opening and closing driving mechanism is connected with the vibration transmission mechanism, and the other end of the opening and closing driving mechanism is connected with the tamping arm, so that the vibration generated by the vibration excitation mechanism is transmitted to the tamping arm through the vibration transmission mechanism and the opening and closing driving mechanism in sequence; the distance between the two ends of the opening and closing driving mechanism is variable and is used for driving the tamping arm to generate an inward tightening movement trend; the vibration transmission mechanism is connected between the vibration excitation mechanism and the opening and closing driving mechanism, and the vibration excitation mechanism and the opening and closing driving mechanism are separately arranged, so that the problem of high maintenance cost caused by the fusion design of a bearing outer sleeve of the clamping oil cylinder and the eccentric shaft in the traditional scheme is solved, damaged parts are independently replaced, and the maintenance cost is reduced.
The middle part of the tamping arm 4 is hinged with a fixed point, one end of the tamping arm 4 is hinged with the opening and closing driving mechanism 3, and the other end is connected with the tamping pick. The opening and closing driving mechanism 3 can drive the tamping arm 4 to rotate relative to the fixed point in the process of stretching. As shown in fig. 1, when the opening and closing driving mechanism 3 extends, the driving arm 4 is driven to rotate anticlockwise, so that the effect of tightening and clamping the tamping pick is generated; when the opening and closing driving mechanism 3 is shortened, the driving arm 4 is driven to rotate clockwise, and the effect of releasing the tamping pickaxe is generated.
The present embodiment provides a specific implementation manner of the vibration transmission mechanism 2: the middle of the vibration transmission mechanism 2 is hinged to a fixed point so that the vibration transmission mechanism 2 can rotate around the fixed point. One end of the vibration transmission mechanism 2 is hinged with the excitation mechanism 1, and the other opposite end is hinged with the opening and closing driving mechanism 3. The vibration generated by the excitation mechanism 1 enables the vibration transmission mechanism 2 to swing slightly around the fixed hinged point, so that the opening and closing driving mechanism 2 is driven to generate small displacement, and the vibration transmission of the vibration transmission mechanism 2 as a medium is realized.
One specific way is as follows: the vibration transmission mechanism 2 is in a connecting rod shape, and the middle part of the connecting rod-shaped vibration transmission mechanism 2 is provided with a hinge hole which is used for correspondingly matching and rotating with a hinge shaft arranged at a fixed point; or, the middle part of the vibration transmission mechanism 2 is provided with a hinged shaft which is used for correspondingly matching and rotating with a hinged hole arranged at a fixed point. The top end of the vibration transmission mechanism 2 is connected with the excitation mechanism 1, and the bottom end is connected with the opening and closing driving mechanism 3.
Or, another specific way: the vibration transmission mechanism 2 is disc-shaped, and the middle part of the disc-shaped vibration transmission mechanism 2 is provided with a hinge hole which is used for correspondingly matching and rotating with a hinge shaft arranged at a fixed point; or, the middle part of the vibration transmission mechanism 2 is provided with a hinged shaft which is used for correspondingly matching and rotating with a hinged hole arranged at a fixed point. The top end of the vibration transmission mechanism 2 is connected with the excitation mechanism 1, and the bottom end is connected with the opening and closing driving mechanism 3. Alternatively, the excitation mechanism 1 and the opening and closing drive mechanism 3 may be connected to any part of the vibration plate.
Alternatively, the vibration transmission mechanism 2 may be a structure other than a link or a vibration plate, and the present embodiment is not limited thereto.
The vibration excitation mechanism 1 in the tamping device shown in fig. 1 is an eccentric vibration excitation mechanism, and comprises an eccentric shaft, and the rotation center of the eccentric shaft is horizontally arranged.

When the excitation mechanism 1 stretches leftwards by a small margin, the vibration transmission mechanism 2 is driven to rotate anticlockwise by a small margin relative to a fixed point; when the excitation mechanism 1 contracts rightward by a small margin, the vibration transmission mechanism 2 is driven to rotate clockwise by a small margin relative to a fixed point, so that the vibration transmission mechanism generates vibration.

The tamping arms 4 on the two sides form a pair of operation tamping arms for tamping one sleeper, so that the railway ballast is concentrated below the sleeper.

One ends of the two excitation mechanisms 1 are hinged to the same fixed point, and the other ends of the two excitation mechanisms are hinged to the top end of one vibration transmission mechanism 2 respectively. The bottom end of one vibration transmission mechanism 2 is correspondingly hinged with one opening and closing driving mechanism 3, and one tamping arm 4 is correspondingly hinged with one opening and closing driving mechanism 3.

The tamping arms 4 on the two sides form a pair of operation tamping arms for tamping one sleeper, so that the railway ballast is concentrated below the sleeper.
Compared with the scheme shown in fig. 4, the scheme shown in fig. 5 saves one excitation mechanism 1 and one vibration transmission mechanism 2, and two opening and closing driving mechanisms 3 are connected to the same vibration transmission mechanism 2, so that the space can be further saved, the structure can be simplified, and the manufacturing cost can be reduced.
In addition to the above scheme, the vibration transmission mechanism 2 is also provided with more than three movable hinged ends, can be connected with a greater number of opening and closing driving mechanisms 3 and correspondingly connected with the tamping arms 4, so that the double-sleeper tamping mechanism can simultaneously tamp two sleepers; or the obtained three-sleeper tamping mechanism can simultaneously tamp three sleepers.
