れており、運搬容易となつている。 Examples will be described with reference to the drawings. A pair of vertical rods 1 are incorporated into a part of the frame and supported by pillars P. A threaded rod 2 is suspended from a wire w hanging from a large pulley W. The weight G is locked to the lower end of the threaded rod 2 by a nut N. Current balancers function with the above structure. The present invention is attached thereto, and the spring receiving plate 3 is movable up and down along the threaded rod 2, and is locked to the lower end of the threaded rod by a nut 4. This spring receiving plate 3 is a strip-shaped plate provided with a bottomed spring cylinder 3a, into which a spring 5 is inserted. The pressing plate 6 is also a strip-shaped plate, placed on the spring receiving plate via the spring 5, and has a hole in the center thereof into which a nut N can be freely inserted. This pressing plate has a notch 6a into which the rod 1 can be inserted from the side, and brackets 6b protrude from both sides of the notch. The press plate can be moved up and down along the rod 1. The bracket 6b is provided with a shaft 6c,
A cam 7 is rotatably supported on this. The cam 7 can be brought into frictional contact with the rod 1 by rotation, and at the point where the cam 7 can make frictional contact with the rod 1, a receiving piece 8 is fixed to a pressing plate on the back of the rod. The shaft 6c and the cam 7 are connected to the bracket 6b.
Make it easy to put on and take off. Protrusions 7a and 3b are provided on the cam 7 and the spring receiving plate 3, respectively, and the two are engaged with each other. When the spring receiving plate 3 is lowered relative to the pressing plate 6, the cam 7 rotates and presses the rod 1 due to the engagement between the protrusions 7a and 3b. The temporary fixing bolt 9 passes through the spring cylinder 3a, has an upper end locked to the pressing plate, and a lower end temporarily fixes the spring receiving plate to the pressing plate with a temporary fixing nut 10. That is, the parts of the present invention are integrated into one piece, making it easy to transport.

Remove c and cam 7, assemble them into rod 1, and then reinstall them. The spring receiving plate 3 and the pressing plate 6 are integrated with a temporary fixing bolt 9 via a spring 5 inserted between them, and a screw 2 is inserted into a hole in the center of the plate and tightened with a nut 4. Attach to the bottom of weight G. At this time, both protrusions 7a and 3b are kept in a proper engaged state. After that, temporarily tighten the nut 1
Remove 0.

る。 Installation is now complete. When a break occurs in the overhead contact line, the weight, pressure plate, and spring support plate try to fall suddenly, but the spring support plate separates from the pressure plate due to the action of the spring, causing the cam to rotate. . The fall is stopped by the frictional engagement between the cam and the rod. As described above, a feature of the present invention is that it can be attached to an existing balancer as is and the desired effect can be achieved.
