Abstract

PURPOSE:To prevent a collector head from loosing contact with a trolley wire and to make it possible to observe the right or left deviation of the trolley wire visually from a work stand, by dividing a vertical shaft into two and making a toggle joint of a main arm and a subarm, and fitting the base part of the main arm to the stand frame with an axle, and fitting a pantograph body to the free end of the subarm with ant axle. CONSTITUTION:A vertical shaft is divided into two, and a toggle joint of a main arm 2 and a subarm 7 is made. The center of the base part of the main arm 2 is fitted to a stand frame with an axle, and the base end part is pulled by a spring 6 to energize rising. Besides, the subarm 7 has a bent part 7a, and is fitted with an axle to the main arm 2 at the bent base part. Besides, the end part of the bent part 7a is tied to a stand board 1 with a tie rod 9, and constitution is so made that the subarm 7 may also rise by the rising of the main arm 2. And a pntograph body 12 is fitted to the free end of the subarm 7 with an axle, and attitude controlling rod 14 is provided in parallel with the subarm 7. And the pantograph body is always kept vertical regardless of the inclination of the subarm 7, by the approximate parallelogram movement between the rod 14 and the subarm 7.

Description of the Related Art Since a trolley wire is stretched in a left-right zigzag manner, it is inspected whether or not the trolley wire reciprocates left and right within a specified range on a current collecting boat of the vehicle before or after the vehicle normally starts running or periodically. I have to keep it. For this reason, inspection using a railroad vehicle is performed. A railroad vehicle is a vehicle that has four wheels that can travel on the rail in addition to four wheels that can travel on the ground and that can be switched as needed.

A lower horizontal axis of a rectangular frame F having vertical and horizontal axes fixed to a vertical axis is rotatably supported on a support base, and a torsion spring S is attached to the lower horizontal axis to urge the frame body to rise. The pantograph main body P is attached to the horizontal axis. A tie rod R is attached, which does not affect the ups and downs of the frame,
It also keeps the axis of the pantoscope always vertical.

適否判定に困難があった。However, since the trolley wire is pushed up by the rigid frame body, it is difficult to adapt to the height change of the trolley wire, and there are many derailments due to the frame body tilting during inspection traveling. Further, since the panther body P is far from the work table of the railroad vehicle and it is difficult to visually inspect it, it is difficult to determine whether the deviation is appropriate.

垂直に保たれるようにしておく。A vertical axis of a known example is divided into two parts to form a toggle joint of a main arm and a sub arm. The main arm is pivotally attached to the underframe at the center of the base, and the base end is pulled by an attached spring to urge the rising. A bending part is made on the sub arm and is pivotally attached to the main arm at the bending base. Connect the bent arm end of the sub arm to the base with a tie rod so that the sub arm also rises when the main arm rises. Although the panter body is pivotally attached to the open end of the sub arm, a posture control rod is provided in parallel with the sub arm, and the substantially parallelogram movement of this rod and the sub arm makes the panter body independent of the inclination angle of the sub arm. Keep it always vertical.

When the folding restraint of this device is released, both the main and sub arms stand up as shown in FIG. 1, and the trolley wire is pushed up by the current collecting boat. Since it is pushed up by the toggle joint, the current collecting boat does not get familiar with the undulation of the trolley wire and does not cause separation.
