Abstract

PURPOSE:To execute easily an overall measurement by providing at least three turning pieces and damping pieces on a pedestal, and installing a push spring and a spring. CONSTITUTION:A roller 10 is made adjacent to a trolley line 24 by supporting a supporting rod 1, by drawing a tow rope 20 in this way, the trolley line 24 is inserted between the roller 10 and a light shielding material 13. The roller 10 is hooked onto the trolley line 24, and subsequently, moved along the trolley line 24 by a supporting rod 1 by loosening the tow rope 20 and bringing the light shielding material 13 into contact with the lower face of the trolley line 24. In this way, an abrasion state of the trolley line is read continuously by a scale plate 23.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trolley equipped with a measuring device so as to be able to move along a trolley wire in order to determine the location of the vehicle.

The contact wire is worn out by the sliding movement of the pantograph, and when the wear becomes significant, it breaks. For this reason, the contact wire has a wear limit claw corresponding to the nominal cross-sectional area, taking into account the safety factor. Whether or not the wear limit has been reached is determined by a person climbing up the overhead wire using a ladder or the like and measuring the remaining diameter of the contact wire with a micrometer or the like.

Since the lifespan of Toro IJ wires is often influenced by local wear rather than overall wear, it is necessary to measure the entire surface of Kiruta TJ.

This invention applies to both live wires and dead wires! The hanger ears, where contact wires are hung at intervals of 1.5 mm, are also provided with a trolley for the trolley wire wear measuring instrument, which can be moved along the contact wire without having to be repaired.

To achieve this objective, the present invention comprises a pedestal fixed to one end of the support rod, and a distance of 1 inch along one edge of the pedestal.・At least three rotating pieces provided on the pedestal so that they can rotate only to one side of the pedestal and move a limited length perpendicular to the direction of rotation, and a rotating piece J -10 A brake piece provided on the base so as to engage with -'I'j5 in the direction perpendicular to the rotation direction and suppress the rotation of the rotating piece, and one end of the rotating piece to engage with the brake piece and hang it. a push spring disposed at the center of rotation of the rotary piece to push the rotary piece toward the brake piece; A contact wire equipped with a spring with a q girder on both sides, and several rollers arranged in a row on each rotary piece so that the rotation center line of the rotary piece and the center line are at right angles and are located outside the pedestal. This is a trolley for an IG4 wear measuring instrument.

An embodiment of the bogie of the present invention will be described with reference to the drawings.

A rectangular plate-shaped pedestal is fixed to one end of the support rod at right angles to the support rod. Three U-shaped notches 3 are formed at intervals along one longitudinal edge of the pedestal λ.

Inside the notch 3, an L-shaped rotating piece 11 shorter than the entrance width of the notch 30 is arranged such that one side of the L-shape is located within the notch 3 and the other side protrudes. The support 1111+left is planted at both ends near the end of one side of the rotating piece so that it protrudes, and the protruding part rotates into the hole provided in the opposing wall of the notch 3 and moves in the axial direction. It has been inserted so that it can be inserted.

On the other side of the pedestal λ, a supporting part B is integrally provided with the pedestal so as to pass near the entrance of each notch 3 from one end to the other, and a rotating piece is provided on the other side of the pedestal λ. This is to prevent it from rotating around the support 1qb s. With such a notch 3 and support part B provided on the pedestal λ (J and a rotating piece G on the pedestal), it is possible to move in the axial direction by the support shaft S. It can also be provided so that it can rotate on one side.

A coiled push spring 7 is inserted between the rotating piece and the pedestal λ on the outer periphery of the support shaft on the same side of each rotating piece lt. is forcing it on. Push 7
On the opposite side of the pedestal λ, a brake piece g is fixed to the pedestal so as to overlap with the end of the rotary piece g in the notch 3. The rotating piece G pressed against the support part B and the brake piece G is held so as not to rotate around the support shaft 12. On the other hand, when the rotating piece g is moved to the other side by compressing the spring 7, the rotating piece is removed from the brake piece g, and the support 1Ili 3 is moved to I! As l+, it can be rotated from the - side of the pedestal.

A plate-shaped spring 7 is attached to the center of the rotating piece on the pedestal λ so as to extend at right angles to the support.
C is pressed against the support part A by the support part A. Note that the push spring 7 may be provided between the end of the support shaft S in the pedestal λ and the bottom of a hole that holds the left support shaft of the pedestal S. A roller 10 is provided on the outer surface of the other side of the figure 14 shape of the rotating piece, the center line of which is perpendicular to the direction of rotation of the rotating piece.
The rollers 10 of each rotating piece are rotatably mounted so as to form a line.
