Since it is necessary to perform the operation within 3 to 4 hours from the last train to the first train, the section where adjustment is possible is limited, and the efficiency is extremely poor.

[0004] The present invention has been proposed in view of the above point, and an object of the present invention is to improve the efficiency of work and to eliminate the problem of shortage of labor by adjusting the disorder by mechanical force.

[0005]

The structure of the straightening machine according to the present invention is as follows.

An outer frame having a fixed pile slidably held in a vertical direction and an inner frame holding portion formed horizontally in a lower portion; An inner frame formed by attaching a movable hook fitting to the outside and a floating prevention hook fitting to the inside, and the tip of the cylinder rod is fixed to the outer frame at the lower surface on both sides while being slidably held on both sides, A moving cylinder in which a part of the cylinder outer cylinder is fixed to the inner frame, and a vibration motor attached to the fixed pile in order to insert the fixed pile into the roadbed,
Street straightener for crushed stone track.

[0007] It is also possible to fix the cylinder outer cylinder side of the movable cylinder to the outer frame and fix the tip of the cylinder rod to the inner frame. Next, it is preferable that the distance between the moving hook metal member and the floating prevention hook metal member can be freely adjusted by a distance adjusting bolt.

[0008]

[Function] The street straightening machine is transported on a track to a target work location by a work vehicle. At a predetermined location, a movable hook fitting and a floating prevention hook fitting are first lowered onto a rail.
Next, the moving cylinder is set near the center of the extruding stroke, and then the vibration motor is driven to drive the fixed pile into the roadbed to a predetermined position. As a result, the fixed frame is fixed. Next, when the moving cylinder is operated, the inner frame moves, the moving hook fitting engages outside the rail, the floating prevention hook fitting engages inside the other rail, and further drives the moving cylinder, A force is applied to the outer rail, and the rail moves together with the macula trees. This reaction force is received by the fixed pile, and the floating force acting on the inner frame frame by the moving force is prevented by the floating prevention hook being hooked on the opposite rail. The track moves by a predetermined amount, the street is measured from the reference pile, and when it returns to normal, the moving work is stopped, and this work is performed at several places in the section where it is not straight, so that all street irregularities are properly corrected. . When the straightening work is completed, when the fixing pile of the straightening machine is pulled out by the work vehicle, the outer frame and the inner frame are also suspended, so that the work returns to the next work place or work base.
