Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track straightening machine that adjusts the height, level, and track of a track while running on the rails of a track, and particularly relates to the rail lifting and lateral pushing devices thereof. .

In order to use a track straightening machine to level, level, and track the rails of a track, the track straightening machine is stopped at the position where the track should be straightened, and the rail elevation device installed on this track straightening machine is used. By the rail catch of
It is necessary to grab the rail and raise it a certain amount above the trackbed. After adjusting the height and level of the elevated rail using this rail lifting device, at the same time, a side pushing device is activated by a signal from a detection device installed in the track straightening machine. ,
The rail supported by the rail lifting device is laterally moved by a predetermined amount to straighten the track.

In this way, when leveling track rails, two tasks are essential: leveling, which involves raising the rail and adjusting its height and level, and street alignment, which involves moving the rail laterally. However, conventionally, the rail lifting device and the lateral pushing device were each installed separately on the track straightening machine. However, separately providing the rail lifting device and the lateral pushing device as in the conventional type has the disadvantage that the overall structure of the straightening machine becomes complicated and larger.

The present invention was proposed in order to overcome the drawbacks of the conventional type, and its purpose is to attach wheels for horizontal pushing to the catch box of the rail hoisting device, and also to remove the entire catch box. By making the track straightening machine movable in the lateral direction using a lateral push cylinder, we have created a lateral push device that has a simple configuration and can perform both rail hoisting and lateral push work. It is about providing.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments.

In the figure, reference numeral 1 denotes left and right catch boxes, and the catch boxes 1 are supported by lifting cylinders 2 so as to be movable up and down with respect to the underframe of the track straightening machine. Furthermore, links 3 are provided on the side surfaces of the left and right catch boxes 1, respectively, for regulating the lateral movement of the left and right catch boxes 1.
One end is connected to the underframe of the track straightening machine. Inside each catch box 1 is a pair of rail catches 4.
is built in so that it can rotate freely. This rail catch 4 is rotated by catch cylinders 5, 5 which are pivotally connected to the catch box 1, and is configured to grip the rail R below the catch box or store it inside the catch box 1. has been done. The left and right catch boxes 1 are connected at their central portions by pipes 6a and 6b which are slidably assembled together. That is, by making the pipes 6a and 6b expandable and retractable, the distance between the left and right catch boxes 1 can be varied.

A support frame 7 is attached to the left and right catch boxes 1 so as to protrude in the front and rear direction (longitudinal direction of the rail).
is fixed, and a horizontal push wheel 8 is mounted on this support frame 7.
is rotatably supported. Further, rods 10 and 10' of horizontal push cylinders 9 and 9' are connected to the front and rear support frames 7 in a direction perpendicular to the longitudinal direction of the rail. These horizontal push cylinders 9, 9' are
Support arm 1 fixed to the center of the underframe of the track straightening machine
It is pivotally attached to the lower end of 1.

The horizontal push wheel 8 is, for example, the inner flange wheel 1.
2 and an outer flange 13 rotatably assembled to the inner flange wheel 12. Inner tsuba wheel 12
is rotatably supported on a support shaft 14 provided on the support arm.

On the other hand, the outer flange 13 is also rotatably supported on the support shaft 14, but as shown in FIG. The short diameter portion is dimensioned so as not to engage with the rail head. This outer flange 13 is provided with a storage mechanism for rotating it 90 degrees. As this storage mechanism, as shown in FIG. 5a, a mechanism using gears is employed in this embodiment, but the outer flange 13 may also be rotated by a link or the like. That is, in FIG. 5a, a gear 15 is integrally formed on the outer surface of the outer collar 13. A drive gear 16 meshes with this gear 15, and this drive gear 1
A shaft 17 of No. 6 is extended in the side direction of the luggage box 1 while being supported by the support frame 7. The end of the shaft 17 is supported by a support plate 18 provided on the side of the cargo box 1.
A link 19 is connected to the end of the shaft 17. This link 19 is connected to the storage mechanism of each horizontal push wheel 8 provided at the front and rear of the catch box 1, and is used to interlock the front and rear outer flanges 13.
The rods are connected. Further, this storage cylinder 20 is supported by a support plate 18 fixed to the side surface of the storage box.

The rail-up lateral pushing device of the present invention has the above-mentioned configuration, and its operation will be explained next.

During rail hoisting work, the lifting cylinder 2 is operated in the same way as in a conventional rail hoisting device using a catch box, and the catch box 1 is lowered close to the rail. In this state, the catch cylinder 5 provided in the catch box 1 is operated to rotate the rail catch 4 downward about its support shaft, and the rail R is gripped by this rail catch.
After the rail R is gripped by the rail catch 4, the lifting cylinder 2 is operated to raise the catch box 1, and the rail R is also raised together with the catch box 1.

In this way, in order to horizontally push the raised rail R and straighten it accordingly, the entire catch box 1 holding the rail R is pushed in the lateral direction using the horizontal push cylinders 9 and 9'. (in the longitudinal direction of the sleeper), and the rail R is moved laterally by the horizontal push wheels 8 provided on the catch box 1. In this case, the inner flange wheel 12 of the horizontal push wheel 8 is
When the catch box 1 is lowered onto the rail R, it is in contact with the surface of the rail R. Therefore, when pushing the rail R outward, the flange of the inner flange wheel 12 is pressed against the surface of the rail R. As it engages the head, the rail R moves outward with the catch box.

On the other hand, the horizontal push cylinders 9, 9' rods 10, 1
0' to move the rail R inward, the outer flange 13 of the lateral push wheel 8 is engaged with the head of the rail. In this case, the outer flange 13 has an oval shape, and only its long diameter portion engages with the rail, so when pushing sideways, this outer flange 13
Rotate 90 degrees so that the long diameter part engages with the head of rail R. In order to rotate this outer flange 13, a storage cylinder 2 provided on the side of the catch box 1 is used.
0 to rotate the shaft 17 via the link 19 connected thereto. That is, a drive gear 16 is fixed to this shaft 17, and moreover, this drive gear 16 meshes with the gear 15 of the outer collar 13, so that the storage cylinder 20
By this operation, the outer flange 13 is rotated by a predetermined angle and can be engaged with the rail R.

In addition, when moving the track straightening machine within the work zone when performing continuous horizontal pushing work on the rail, the catch box 1 remains lowered and the rail catch 4 is moved.
remains engaged with the head of rail R and does not apply pressure to the catch cylinder. Furthermore, if only the outer flange 13 of the side push wheel 8 is rotated by the storage cylinder 20 so as not to engage with the head of the rail R, the catch box can move on the rail while being supported by the inner flange wheel 12. You can run and move to the next lift device.

Next, in order to store this rail up-and-side pushing device, the catch cylinder 5 in the catch box 1 is operated, the rail catch 4 is lifted upward, and the rail R is released from the rail catch. Also, for the side push wheel 8, by operating the storage cylinder 20, the outer flange 13 is rotated 90 degrees so that its short diameter part is on the rail R side, and the side push wheel 8 and the rail are rotated. Release the engagement with R. In this state, if the entire catch box 1 is lifted up by the lifting cylinder 2, the track straightening machine can perform forward travel, etc.

As described above, the rail climbing lateral pushing device of the present invention is configured such that the catch box of the rail climbing device is provided with a lateral pushing wheel, and the catch box is further configured to be movable in the lateral direction by a lateral pushing cylinder. Therefore, compared to the conventional arrangement in which the lifting device and the side pushing device are separately provided on the body of the straightening machine, the overall structure of the device can be made smaller and simpler. In particular, even in a normal lifting device, wheels are provided at the front and rear of the catch box to support the catch box during work movement, but in the present invention, these moving wheels also serve as lateral pushing wheels. With this configuration, there is almost no need to provide any additional members other than the cylinder for the lateral push mechanism, so the overall configuration of the device can be greatly simplified.

In addition, if the left and right catch boxes are slidably connected using pipes as in the illustrated embodiment, so that both can be moved freely, it can easily be used in cases such as a slack bag. Further, by selecting the operation of the horizontal push cylinder, it is possible to push the left and right rails individually or simultaneously.

Furthermore, if the structure is such that the collar can be rotatably stored as in the illustrated embodiment, when moving between sleepers during work, it is only necessary to store the collar and there is no need to raise the entire catch box. Another advantage is that the next horizontal push operation can be performed continuously while the catch box is lowered.

Furthermore, when lateral push wheels are provided at the front and rear of the catch box, as in the illustrated embodiment, the lateral push load on the rails is not concentrated in one place, so that no excessive force is applied to the rails and sudden deformation occurs. It also has the effect of not waking up.
