Detailed Description
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 structural diagram of a tamping device provided in an embodiment of the present application. As shown in fig. 1, the tamping apparatus provided in this embodiment includes: the device comprises an excitation mechanism 1, an opening and closing driving mechanism 2, a tamping arm 3 and a torque eliminating mechanism 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 mode is adopted, and specifically, the mode that the eccentric shaft rotates to generate vibration can be adopted. Alternatively, the excitation mechanism 1 may be configured to generate vibration by a hydraulic, pneumatic, or electric principle.
One end of the opening and closing driving mechanism 2 is connected with the excitation mechanism 1, and the other end is connected with the tamping arm 3. One of the functions of the opening and closing driving mechanism 2 is to transmit the vibration generated by the vibration exciting mechanism 1 to the tamping arm 3 to drive the tamping arm 3 to generate vibration. The tip of tamping arm 3 links to each other with the tamping pick, transmits the vibration for the railway ballast through the tamping pick to make the railway ballast remove to the sleeper below and reach closely knit purpose.
The opening and closing driving mechanism 2 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 2 stretches to drive the tamping arm 3 to generate tightening action so as to promote the ballast to move towards the lower part of the sleeper or generate outward loosening action, which is the second action of the opening and closing driving mechanism 2. The opening and closing drive mechanism 2 may be an oil cylinder, an air cylinder, or another component, 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 3 is hinged with the opening and closing driving mechanism 2, and the other end is connected with the tamping pickaxe.
During operation, the opening and closing driving mechanism 2 generates a torque to the excitation mechanism 1, so that the excitation mechanism 1 tends to rotate in a first direction.
In the embodiment, the torque eliminating mechanism 4 is connected with the excitation mechanism 1 and is used for eliminating the torque applied to the excitation mechanism 1, so that the excitation mechanism is stressed in a balanced manner, and the service life of the excitation mechanism is prolonged.
According to the technical scheme provided by the embodiment, the vibration excitation mechanism, the opening and closing driving mechanism, the tamping arm and the torque eliminating mechanism are adopted, wherein one end of the opening and closing driving mechanism is connected with the vibration excitation mechanism, and the other end of the opening and closing driving mechanism is connected with the tamping arm and is used for transmitting vibration to the tamping arm; 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 the movement trends of inward tightening and outward loosening; the torque eliminating mechanism is connected with the excitation mechanism and used for eliminating torque applied to the excitation mechanism when the opening and closing driving mechanism works, the problem that the service life of the oil cylinder is short due to the fact that the oil cylinder is used for offsetting the torque applied to the excitation mechanism in the traditional scheme is solved, and the maintenance cost of the tamping device is reduced.
The middle part of the tamping arm 3 is hinged with a fixed point, one end of the tamping arm 3 is hinged with the opening and closing driving mechanism 2, and the other end is connected with the tamping pickaxe. The opening and closing driving mechanism 2 can drive the tamping arm 3 to rotate relative to the fixed point in the process of stretching. As shown in fig. 1, when the opening and closing driving mechanism 2 extends, the driving arm 3 is driven to rotate clockwise, so as to generate the effect of tightening the tamping pick; when the opening and closing driving mechanism 2 is shortened, the driving arm 3 is driven to rotate anticlockwise, and the effect of releasing the tamping pickaxe is generated.
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 3 through the opening and closing driving mechanism 2, so that the tamping pick installed at the bottom end of the tamping arm 3 vibrates. Meanwhile, the opening and closing driving mechanism 2 pushes the tamping arm 3 to rotate, so that the tamping pickaxe generates tightening and clamping actions. When the opening and closing driving mechanism 2 pushes the tamping arm 3 to clamp, the torque generated by the clamping force is counteracted by the torque eliminating mechanism 4.
Furthermore, a forked connecting piece 5 is used for connecting the opening and closing driving mechanism 2 and the excitation mechanism 1. Specifically, the bifurcated connecting member 5 has a first connecting portion perpendicular to the first connecting portion and a second connecting portion having a straight structure, and two opposite ends of the first connecting portion are hinged to the two opening and closing driving mechanisms 2, respectively. One end of the second connecting part is fixedly connected to the midpoint of the first connecting part and is perpendicular to the first connecting part. The other end of the second connecting part is fixedly connected with the excitation mechanism 1.
For the torque cancellation mechanism 4, the present embodiment provides an implementation: the torque cancellation mechanism 4 includes: a first moving member and a second moving member. The first moving part is hinged with a fixed point, a moving pair is formed between the first moving part and the second moving part, and the second moving part is connected with the vibration excitation mechanism 1. When the excitation mechanism 1 generates a twisting trend, the first moving part and the second moving part generate relative movement, and the first moving part rotates relative to the fixed point.
A specific implementation manner is as follows: as shown in fig. 1, the first moving member is a sleeve 41, and the second moving member is a link 42. One end of the sleeve 41 is a closed end, and the other end is an open end. The closed end of the sleeve 41 is hinged to a fixed point, and one end of the connecting rod 42 is fixedly connected to the excitation mechanism 1, and the other end is telescopically inserted into the sleeve 41 from the open end.
Another specific implementation manner is as follows: fig. 2 is a schematic structural diagram of another tamping device provided in the embodiment of the present application. As shown in fig. 2, the first moving member is a connecting rod 42, the second moving member is a sleeve 41, one end of the sleeve 41 is a closed end, and the other end is an open end. The closed end of the sleeve 41 is fixedly connected with the excitation mechanism 1, one end of the connecting rod 42 is hinged with a fixed point, and the other end is telescopically inserted into the sleeve 41 from the open end.
The first moving part in the torque eliminating mechanism 5 is hinged to a fixed point, and when the eccentric shaft of the excitation mechanism 1 rotates, the first moving part rotates around the fixed point and slides with the second fixing part, so that the normal motion of the excitation mechanism 1 and the opening and closing driving mechanism 2 is ensured while the clamping torque is counteracted.
The torque eliminating mechanism 4 and the connection part of the forked connection piece 5 and the excitation mechanism 1 are respectively positioned at two opposite sides of the excitation mechanism. One specific scheme is as follows: the connecting line between the torque cancellation mechanism 4 and the connecting point of the bifurcated connecting member 5 and the excitation mechanism 1 passes through the center of the excitation mechanism 1.
In fig. 1 and 2, the opening and closing driving mechanism 2 is connected to the top of the excitation mechanism 1 through the branched connecting member 5, and the torque canceling mechanism 4 is connected to the bottom of the excitation mechanism 1.
