DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger having a trolley wire clamping ear attached to a lower end thereof, branched upward and locked by two suspension wires, the length of which corresponds to a use point one by one. The present invention relates to a crimping device for adjusting and fixing the pressure.

2. Description of the Related Art First, a hanger to be processed by the present apparatus is defined. Conventional hangeyers hang one trolley wire from one stranded wire, but in recent years hang one trolley wire from two horizontally parallel stranded wires and use this as a feeder wire. Instead, there has emerged one in which a separately provided "feeding wire" has been eliminated. The present invention is of this type, and includes three members, a branch fitting 1, a hanger loop 2, and a hanger bar 3, as shown in FIGS. The branch fitting 1 has a branch pipe 1a protruding at both ends of the upper surface of the base material, and a leg pipe 1b protruding at the center of the lower surface. The hanger loop 2 has a loop that can be locked to the suspension line M, and one end thereof is inserted and fixed to the branch pipe 1a. The hanger bar 3 is inserted into the leg tube 1b so as to be able to move in and out, and an ear E is attached to a lower end. Of the above, the hanger loop 2 is not directly connected to the suspension wire M but is locked via the protective cover C. However, in the apparatus of the present invention, the mounting dimension of the protective cover C is taken into account by the scale S. No protective cover is required during processing. The height interval (hereinafter abbreviated as “height” h) to the center of the lower trolley wire changes as the mounting position of the hanger to the suspension line shifts. Since the hanger bar 3 is inserted into and out of the leg tube 1b so as to be freely inserted into and out of the leg tube 1b, it is necessary to adjust the protruding length in accordance with the fluctuation of the height h by design or actual measurement, and then compress the leg tube to be integrated with the hanger bar. No.

[0003]

Conventionally, a worker who cuts a hanger bar and crimps a branch fitting at a factory based on a design value, or a person who has a scale at a site, can perform simple calculations or actual measurements. Calculated the distance between the branch metal fitting and the ear, put the mark so that the position was not deviated, and carried it between the upper and lower dies. As for the overhead height, since a considerable error occurs between the calculated value and the actually measured value, machining at the site based on the actually measured value is mainly used. Therefore, even if it was unavoidable at the prototype stage, after moving to mass production,
There has been a demand for a device that can easily determine the length of a site and press the crimp without error.

[0004]

A hanger loop cradle and a hanger bar cradle which move up and down integrally with the lower die are provided on the left and right sides of the lower die. A pair of engaging pins are planted in the hanger loop receiving stand, and when the hanger loop is locked thereto, the leg tube 1b
Is just above the lower die. A scale parallel to the hanger bar support is attached to the hanger bar support so that the distance h from the receiving pin can be read at the lower end of the hanger bar for adjusting the inside of the leg tube. It is assumed that the target height value is determined in advance by calculation on the drawing or actual measurement at the site.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. As described above, since the dimension of the protective cover C to be put on the suspension line is taken into consideration in the scale S together with the wire diameter of the suspension line, the protective cover is not required for measurement and crimping with the apparatus of the present invention. The upper and lower dies D1 and D2 can compress the leg tube 1b of the branch fitting. The receiving tables U1 and U2 are fixed to the lower die on the left and right sides of the lower die, and operate integrally with the lower die that is moved up and down by a lower hydraulic mechanism. A pair of engaging pins P are implanted in the cradle U1, and when the loop of the hanger loop 2 is locked to this, the leg tube 1b just comes over the lower die D2. A scale S is attached to the cradle U2 in parallel with the hanger bar 3. This scale makes it possible to read the distance from the pin P to the end of the hanger bar. Assuming that the maximum (height) of the interval (height) between the suspension wire and the trolley wire is h1 and the minimum is h2 in a plurality of hangers installed in one intervening space as shown in FIG. 5, the scale S is as shown in FIG. It only needs to be long enough to make the terminal readable.

[0006]

According to the present invention, the pair of hanger loops 2 and 2 are inserted and crimped in advance to the branch fitting. If the hanger bar 3 is mounted between the two cradles of the lower die D2, the crimping can be performed as it is simply by adjusting the hanger bar. It is easy to determine the length corresponding to the predetermined height and there is no risk of misoperation.
