Description

[0001]
[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a tension balancer for maintaining a constant line tension on a square iron pole, and enables mounting of the iron pole regardless of the vertical and horizontal dimensions of the pole.
[0002]
[Prior art]
If the target is a circular column for retaining the tension balancer, it is sandwiched by a pair of semicircular bands, so that it is possible to cope with a column having a slightly different diameter. Further, since the tension balancer is provided on the side of the track so as not to hinder the traveling of the vehicle, the angle of the detent must also correspond to the angle, but this adjustment is extremely easy with a circular column.
[0003]
However, in the case of a square pillar, there are both a rectangular shape and a square shape, and the vertical and horizontal dimensions of the pillar are not always constant, and the joint design must be performed for each shape of the square pillar. Further, in the case of a square pillar, the work is carried out at a high place because holes are made in the steel pole constituent material and bolts are fastened to the mounting member, so that there is always a danger.
Japanese Utility Model Application Laid-Open No. 58-181620 discloses a stopper for a square pillar. A plurality of bolt insertion holes are drilled on the arc of the center of the steel tower on the horizontal plane on one side of the angle steel material to prevent pulleys
A bracket is freely attachable on this arc so that the line of force for retaining the tension balancer is always at the center of the tower. However, in this structure, the range of adjustment of the force line angle is limited, and there has been a problem that the attachment adjustment cannot be performed sufficiently with respect to the retaining angle of the tension balancer.
[0004]
[Means for solving the problem]
Four members having two orthogonal sides and having edges at both ends can be brought into contact with the four corners of the prism, and the corresponding edges of the adjacent members are tightened with bolts to form a tightening frame. As a result, it is possible to mount the rectangular column without making a hole and regardless of the size of the rectangular shape. One side of the vertical side of the angle-shaped mounting bracket is bolted to a long hole in the waterside direction drilled on one outer surface of the tightening frame so that the left and right positions can be adjusted. Separately, a pair of arm retaining bearing plates which are welded upright to the center of a rectangular washer is prepared as a bearing fitting, and the bolt holes drilled at both ends are inserted into the bolt holes 3b drilled on the arc wire of the mounting bracket. Secure with bolts correspondingly.

【Example】
Reference is made to the drawings. An angle R in FIG. 1 indicates a square corner of a square iron pole. On the other hand, the frame piece 1 is provided with edges 1a at the ends of both sides that can abut on the corners. Each of the four frame pieces 1 forms a rectangular fastening frame S by tightening the corresponding edges with bolts 2. The mounting bracket 3 is made up of two orthogonal sides, and a long hole 3a is formed in one vertical side thereof, and is fixed to the corresponding side edge 1b of the frame piece 1 by a bolt 4 so that the left and right positions can be adjusted. If necessary, the holes in the side edges 1b are also elongated holes as shown in FIG. On the other side of the mounting bracket 3 on the horizontal side , bolt holes 3b with a plurality of equal pitches are formed on an arc line. The bearing member 5 is formed by welding a pair of bearing plates 5b upright at the center of a rectangular washer 5a, and has bolt holes at both ends. The bolt holes can be selectively overlapped with two holes 3b on the arc line, and are fixed by bolts 6. That is, the mounting angle of the bearing member 5 can be adjusted to the left and right. Normally, there is no problem if the left and right sides are set to about 5 degrees.
[0006]
The configuration is as described above. In this device, the fastening frame S is attached to a square iron pole as shown in FIG. 4, and is used for the main arm A and the sub arm B. In each case, the arm end is used by being locked to the shaft 5C of the bearing plate. Although both have the same configuration, the design may be changed according to the difference in stress. Although not shown, it can also be used as a tightening frame for attaching the weight of the tension balancer.
[0007]
【effect】
A tension balancer can be attached to a square iron pole regardless of its shape and size and without drilling a bolt hole in the iron pole. The mounting direction can be adjusted to either left or right.
