According to the present invention, in order to solve the above-mentioned problems, claws for fitting to rail heads are provided at both ends of a shaft composed of a horizontal member, and the shaft is laterally suspended between a pair of right and left rails. In a rail gauge adjusting device for a rail, which adjusts a gauge to a predetermined distance by expanding and contracting a shaft body made of a horizontal member in a left-right direction, a claw fitted to a rail head is provided with a clamp mechanism for gripping the rail, A screw rod consisting of a right-hand screw and a left-hand screw is connected symmetrically in the middle of the shaft body with the rotating gear of the ratchet mechanism interposed, and the handle lever of the ratchet mechanism is rotated in one direction to operate the track. The distance between the gauges can be adjusted to a predetermined distance.

Therefore, according to the present invention, when repairing or laying a railway track, the distance between the pair of left and right rails can be easily and quickly adjusted to a predetermined distance. Moreover, since it is simple and lightweight, it is easy to carry.

According to still another aspect of the present invention, the shaft body provided with the claws at both ends is provided with an electric insulating material interposed therebetween. Therefore, according to the present invention, it is possible to work smoothly and safely without short-circuiting the signal circuit of the line while adjusting the rail gauge.

According to still another aspect of the present invention, there is provided a claw clamping mechanism in which a hook having a hook-like lower end is provided on the outside of the hook so as to be tiltable, and the handle is vertically moved by operating a handle lever. The means is that the hook can freely move back and forth to the jaw of the rail.

Therefore, according to the present invention, the handlebar of the ratchet mechanism is used to adjust the gauge when the shaft provided with claws at both ends, which are fitted to the rail head, is laid across the pair of left and right rails. Even when the rotating operation is performed, since the claws firmly grip the rail by the clamp mechanism, the operation of adjusting the gauge can be performed easily and smoothly.

In the figure, reference numeral 6 denotes a claw, which is generally called a catch, which fits into the head of the rail 1, has a U-shaped cross section, and is provided at both ends of a shaft 7 made of a horizontal member. In the case of the present embodiment, a hollow metal frame material is used for the shaft body 7 in order to reduce the weight, but the shaft body 7 can be made to have an appropriate material and shape. Reference numeral 8 denotes a clamp mechanism for gripping the rail 1. A locking piece 9 having a hook-like lower end is provided on the outside of the claw so as to be tiltable, and the handle lever 10 is vertically moved in the direction of the arrow in the figure. , Locking piece 9
Is provided so as to be able to advance and retreat from the outside of the claw to the jaw portion 1a of the rail. Reference numerals 7a and 7b denote threaded rods provided in the middle of the shaft body 7 and composed of a right-handed screw and a left-handed screw, and are connected symmetrically with the rotating gear of the ratchet mechanism 11 interposed therebetween. Reference numeral 12 denotes a handle lever of a ratchet mechanism.
7b, the claw 6 is extended and contracted right and left via the shaft body 7. Reference numeral 13 denotes an electrical insulating material interposed in the shaft body 7, which is formed by dividing a hollow metal frame material and sandwiching and fixing it from both sides. As a result, the signal circuit of the track does not short circuit while adjusting the gauge, so that the operation of the train is not hindered. However, if the shaft 7 is made of an insulating material, the electric insulating material 1
3 can be omitted.

FIG. 2 shows a clamp mechanism 8 for holding a rail.
FIG. 3 is an overall perspective view showing the details of FIG. In the figure, reference numeral 10a denotes a push rod protruding from the tip of the handle lever 10. When the handle lever 10 is vertically moved in the direction of the arrow in the figure, the upper part of the lock piece 9 is pushed to tilt the lock piece 9. It is to let. 14a and 14b are support pieces of the handle lever 10 erected on the surface of the claw 3, and are provided so that the pin 15 can be inserted and the handle lever 10 can rotate. In the embodiment, a pair of right and left is provided, but one side may be supported. 1
