Next, the details of each part of the rail clearance adjuster C will be described with reference to FIGS. The body portion 32 is made by fitting the square tube-shaped movable body 37 in the square tube-shaped fixing body 36 freely back and forth sliding <br/> movement, the rear bracket 38 to the rear end lower surface of the stationary body 36 A front bracket 39 is fixed to the lower surface of the front end portion of the movable main body 37. A leveling push / pull cylinder 35 is connected to the front bracket 39 and the rear bracket 38 by pins 40, and the front bracket 3 is fixed.
9. A front rail grip 33 and a rear rail grip 34 are attached to a support 41 attached to a rear bracket 38, respectively. The front rail gripping portion 33 and the rear rail gripping portion 34 each include a clamp cylinder 42 orthogonal to the rail 1. The cylinder body 43 supports an upper U-shaped frame 44 a of a first gripping claw 44 with a pin 45. Movable body 46
A second gripping claw 47 is supported on the U-shaped groove 46a by a pin 48, and an intermediate portion between the first gripping claw 44 and the second gripping claw 47 is fixed to the brackets 41a and 41b of the support 41 by a pin 49, respectively. When the rail 1 is gripped by the first and second gripping claws 44 and 47 as shown in FIG. 10 when the cylinder movable body 46 of the clamp cylinder 42 is extended, and when the cylinder 1 is reduced as shown in FIG. The grip claws 44, 47 release the grip of the rail 1. A bracket 50 is provided on the front and rear intermediate lower surfaces of the fixed body 36, and a mounting plate 51 is supported on the bracket 50 by pins 52 so as to be vertically swingable.
A downwardly U-shaped frame 53 is attached so as to straddle the adjusting push / pull cylinder 35, and an infrared transmitter 54 and an infrared receiver 55 are attached to the lower left and right sides of the frame 53 so as to face each other. A rail play measuring device D using infrared rays is constituted, and the upper portion of the mounting plate 51 is screwed into a screw rod 57 rotated by a motor 56 to rotate the motor 56 so that the frame 53 swings up and down together with the mounting plate 51. As a result, the rail gap measuring device D moves to a lower position facing the seam 4 of the rail 1 and an upper position above the rail 1. The mounting piece 58 attached to the rear bracket 38 is provided with a photoelectric type seam plate detection sensor 59 for detecting the seam plate 2,

[0010] The electromagnetic switching valve 61, as shown in FIG. 11, the first electromagnetic switching valve 61 ₁ for supplying the discharged pressurized fluid of the first pump 64 to the lining push-pull cylinder 35, the second pump to the clamp cylinder 42 made from the second electromagnetic switching valve 61 ₂ for supplying a discharged pressurized fluid of 65, these first and second electromagnetic switching valve 61
_1, 61 ₂ to be automatically switched manual lever provided on the upper body 13 are also available automatic control together with the driving unit of the drive unit and the arm B of軌陸vehicle A by the controller.

Next, the work of adjusting the rail play will be described. The rail tightening bolt for tightening the rail 1 on one side in the traveling direction and the seam plate bolt 3 for tightening the seam plate 2 are loosened, and the first and second arms 14 and 16 are swung upward to adjust the clearance between the rails. The track machine A is caused to travel along the rail 1 by the iron wheel 12 with the main machine C positioned above the rail 1.
When the rail clearance adjuster C is close to the seam 4 of the rail 1, the rail vehicle A is stopped, and the first and second arms 14, 16 are stopped.
Is pivoted downward to put the rail clearance adjuster C on the rail 1. When the first and second arms 14 and 16 are moved forward at a very low speed to move the rail clearance adjuster C along the rail 1 and the seam plate detection sensor 59 detects the seam plate 2, the first and second arms 14 and 16 are moved.
The second arms 14 and 16 are stopped to stop the rail play adjuster C at the position shown in FIG. With the rail clearance measuring device D as the lower position, the rail clearance S is measured and input to the controller, and the clamp cylinder 42 of the front and rear rail grippers 33, 34 is extended with the leveling push / pull cylinder 35 at the intermediate position, and the first. The rail 1 is gripped by the second gripping claws 44 and 47, respectively. After confirming the grip of the rail, the rail temperature is detected by the rail temperature detector 60 and input to the controller. The controller calculates a correction amount based on the measured rail clearance S, the rail temperature, and the appropriate rail clearance, and displays the corrected amount. the lining push-pull cylinder 35 outputs a switching signal to the to the first electromagnetic change-over valve 61 ₁ at the same time displayed on the extension or contraction little front grip part 3
The distance between the rail 3 and the rear grip 34 is changed to move one of the rails 1 to correct the rail gap.

[0012]

The rail clearance adjuster C can be moved with respect to the rail 1 or set on the rail 1 by the traveling of the track-and-land traveling vehicle A and the vertical swing of the arm B. The machine C can be moved and set mechanically irrespective of human power, thereby simplifying the operation.
34 rail gripping and releasing operation and front and rear rail gripping part 3
Since the movement of the clamps 3 and 34 is performed by the clamp cylinder 42 and the adjusting push / pull cylinder 35, no manual operation is required and the operation is simplified. it can. The seam plate detection signal from the seam plate detector 59 can detect that the rail clearance adjuster C has matched the rail seam 4, the rail clearance measuring device D can measure the rail clearance, and the rail temperature detector 60 can detect the rail temperature. Can be detected, so that they can be automatically controlled.
