Problems solved by technology

Although the pulling cylinder mentioned above can indicate the degree of tension of the oblique stay wire, it is necessary to cut off the steel strand of the oblique stay wire during installation and install it between the upper and lower steel strands. When the pulling cylinder is damaged, it is very difficult to disassemble and install Complicated, and after one strand is divided into upper and lower strands, the possibility of loosening is increased

Embodiment 1

[0038] This embodiment provides a tension indicator, which can indicate the tension degree of the oblique stay wire during use, so as to be adjusted at any time.

[0039] figure 1 A partial structural schematic view of the stay wire provided in Embodiment 1 of the present invention is shown, and the stay wire includes fastening hardware, steel strands and ground anchors. The fastening hardware includes a U-shaped outer frame, a stay wire hardware and fastening bolts. The wire-staying fittings can pull the steel strand, and at the same time receive the reverse tension of the steel strand. The ground anchor is connected to the arc-shaped rod of the U-shaped outer frame, and can pull the U-shaped outer frame.

[0040] In this embodiment, the cable fittings of the oblique cable are provided with two through holes at intervals, and the two arms of the U-shaped outer frame can respectively pass through the two through holes, so that the cable fittings are sheathed on the U-shaped out...

Embodiment 2

[0057] This embodiment provides a cable-stayed wire, which is different from the cable-stayed wire in Embodiment 1 in that the number of tension indicators installed on the fastening hardware is different. Figure 8 It shows a partial structural schematic view of the oblique wire provided in Embodiment 2 of the present invention, refer to Figure 8 In this embodiment, the two arms of the U-shaped outer frame of the fastening fittings for the obliquely stayed wires are respectively fitted with one of the tension indicators, and the installation method of the two tension indicators is the same as that of the first embodiment.

[0058] When the oblique stay wire becomes loose, directly observe the readings of the tension indicators on the two arms of the U-shaped outer frame to directly know the position where the oblique stay wire becomes loose, and adjust it in time. In addition, installing tension indicators on the two arms can make the cable and its fastening hardware more ba...

Embodiment 3

[0060] The difference between this embodiment and the first embodiment lies in that the indicating device 200 of the tension indicator provided by this embodiment is different from that in the first embodiment.

[0061] The supporting plate 250 of the indicating device 200 provided in this embodiment protrudes from the accommodating cavity 110 to open a waist-shaped hole, and the indicating block 220 is passed through the waist-shaped hole, and the position can be moved, and two locking pieces 260 can be used to Be fixed to indicate the tension scale value or tension value.

[0062] Specifically, the indicating block 220 is an indicating screw, which is passed through the waist-shaped hole, and its position can be adjusted. The tip parts located at both ends of the indicator screw can replace the function of the indicator needle 240 to indicate the tension scale value or tension degree value on the tension scale 230 in the use state.

[0063] More specifically, the locking me...

Abstract

The invention belongs to the technical field of electric pole installation, and discloses a tension indicator and an inclined stay wire. The tension indicator comprises a fixing seat, an indicating device and an elastic element, a containing cavity is formed in the fixing seat, and a sliding groove is formed in the side wall of the containing cavity; the indicating device comprises a movable block and an indicating block, the movable block is movably arranged in the containing cavity in a penetrating mode, and the indicating block is located outside the containing cavity and connected to the movable block through the sliding groove; the elastic element is located between the cavity bottom of the containing cavity and the movable block, and when the movable block slides towards the cavity bottom of the containing cavity, the elastic element can be compressed. The tension indicator can intuitively observe whether the stay wire is loosened on the basis of ensuring the integrity of the stay wire, and timely maintain the stay wire so as to adjust the loosening phenomenon of the stay wire caused by various factors, ensure that the stay wire is kept in a tight state, and avoid dangers caused by shaking of an electric pole.

Description

technical field [0001] The invention relates to the technical field of pole installation, in particular to a tension indicator and a diagonal stay wire. Background technique [0002] In the distribution lines of the distribution network, the pole is a commonly used line laying device. It is characterized by simple structure and low cost, and is very suitable for large-scale and extensive laying. However, compared with the iron tower, the chassis of the pole has a smaller contact area with the ground, which is not conducive to stable fastening installation. Therefore, in order to balance the problem of unbalanced pulling force of the power transmission cable at the top of the pole and to ensure the stability of the installation of the pole, it is necessary to pull and fix the inclined cable. The oblique stay wire can pull and control the pole from different angles, which greatly improves the anti-dumping ability of the pole body. [0003] The cable-stayed wire is composed o...
