Each ejector rod 12 is rotatably connected in the notch 11 through a torsion spring 31; by arranging the torsion spring 31, the V-shaped elastic sheet 13 is assisted to reset the ejector rod 12, so that the end part of the ejector rod 12 can be stably embedded in a gap between adjacent latches 15.
Working principle: in the embodiment of the invention, the electric power maintainer can operate only on the ground, so that the ascending operation is avoided, meanwhile, the approach to a bare cable is avoided, and the danger of electric contact is reduced; the transverse plate 1 is clamped at the end part of the telegraph pole and is fastened by the long screw 3; the cable is arranged between the supporting plate 7 and the pressing plate 8, and then the cable is clamped and fixed through the fastening bolt 9; when a cable sags seriously, an operator holds a long rod, the end part of the long rod is fixedly connected with an inner hexagon sleeve, the inner hexagon sleeve is sleeved on the hexagonal prism 6, then the long rod is rotated to drive the screw rod 5 to rotate, and due to the arrangement of multi-stage threads on the screw rod 5, the lifting height of a supporting block close to the upper layer is larger than that of a supporting block below, at the moment, the gap between two adjacent cables is gradually increased, the possibility of contact between the upper cable and the lower cable is reduced, and the safety of power transmission is ensured; the operation on the ground is avoided, the ascending operation is ensured, the safety is ensured, the operation away from the high-voltage bare cable is realized, the danger is reduced, meanwhile, the long rod is used, the moment is increased, and the labor intensity of circuit maintenance personnel is reduced;
the cable is erected in the air, the cable is blown by wind, high frequency and long time vibration are carried out, meanwhile, the cable self-gravity presses down the supporting plate 7, the supporting plate 7 can be forced to rotate by itself, the supporting plate 7 gradually moves downwards, and the upper and lower adjacent cables are contacted again, therefore, according to the problems, the rotation between the screw 5 and the vertical plate 2 is restrained by arranging the ejector rod 12; when the inner hexagon sleeve is sleeved on the hexagonal prism 6, the inner side wall of the inner hexagon sleeve extrudes the ejector rod 12, the ejector rod 12 is extruded and rotated into the notch 11, at the moment, the end part of the ejector rod 12 is separated from the latch 15, the long rod is rotated, the screw rod 5 is rotated, and upward movement of the supporting plate 7 is realized; when the inner hexagonal sleeve is separated from the hexagonal prism 6, the ejector rod 12 loses extrusion of the inner side wall of the inner hexagonal sleeve, the ejector rod 12 is reset under the elasticity of the V-shaped elastic sheet 13, the end part of the ejector rod 12 is embedded in a gap between the adjacent clamping teeth 15 again, even if the inner hexagonal sleeve is separated from the ejector rod 12, the ejector rod 12 is reset and cannot be embedded in the gap, and under the condition of later wind blowing and vibration, when the screw rod 5 rotates, the end part of the ejector rod 12 can be smoothly embedded in the gap, so that the stability of the screw rod 5 is ensured, and the screw rod 5 is prevented from rotating automatically;
when the inner hexagon sleeve is sleeved on the hexagonal prism 6, the hexagonal prism 6 is sleeved completely by the inner hexagon sleeve, only then, the inner side wall of the inner hexagon sleeve can effectively extrude the inner hexagon sleeve to separate the end part of the inner hexagon 12 from the latch 15, and meanwhile, the hexagonal prism 6 is completely sleeved by the inner hexagon sleeve, so that the extrusion stress area between the inner hexagon sleeve and the hexagonal prism 6 is ensured, slipping caused by small contact area between the inner hexagon sleeve and the hexagonal prism 6 is prevented, and the side edges on the surface of the hexagonal prism 6 are polished smoothly, so that slipping occurs between the inner hexagon sleeve and the hexagonal prism 6;
the clamping plate 16 with a plurality of clamping legs 17 is arranged at the end part of the ejector rod 12, so that the stability between the ejector rod 12 and the clamping teeth 15 is increased, the end part of the ejector rod 12 is reduced to be scratched and worn by the clamping teeth 15 for a plurality of times, and the end part of the ejector rod 12 is prevented from losing the effect of clamping the clamping teeth 15;
the cable is embedded in the groove 18, and then the bolt 9 is tightened; because the cable fixing device is used for fixing the cable, the cable is required to be lifted, various installation tools and components are carried on the body, if the components fall off during fixing, firstly, the components fall on the ground and then are prepared, or other auxiliary maintenance personnel ascend to feed, the construction operation period is prolonged, secondly, the components fall off and can cause accidental injury to ground personnel, therefore, the end part of the pressing plate 8 is rotated on the rotating shaft 19, the rotating shaft 19 passes through the rectangular grooves 21 of the L-shaped plate 20, namely, the pressing plates 8 are connected onto the supporting plate 7, so that the operation of field operators is facilitated, and the possibility of uneven preparation is reduced;
the grooves 18 on the upper and lower adjacent supporting plates 7 are arranged in a left-right staggered mode, so that when cables in the grooves 18 sag, the cable sagging parts are distributed in a staggered mode, the possibility of electrical contact of the cables of the lower vertical line is reduced, and the situation is suitable for a cable laying space without external wind or gas flow, and the cables do not swing and contact naturally; the extrusion plate 23 and the connection plate 25 are arranged, so that the cable with serious sagging is also tightened, and the possibility of electrical contact between the upper and lower adjacent cables is increased; the adjusting bolt 22 is rotated, the adjusting bolt drives the extruding plate 23 to approach to the direction of the transverse plate 1, meanwhile, the extruding plate 23 is pushed to approach to the direction of the transverse plate 1, and the fixed pulley 26 on the connecting plate 25 extrudes the cable, so that the cable is gradually in a tight state, the sagging amplitude of the cable between two telegraph poles is reduced, and the possibility of electrical contact of the cable is reduced; the cable is a bare cable, insulation between the cable and the fixing device is naturally considered, and the operation of using insulating materials and the like by partial parts is considered by the person skilled in the art; the anti-falling plate 28 is arranged on the fastening bolt 9, so that the problem of unexpected falling of the fastening bolt 9 or uneven stock preparation of the fastening bolt 9 is also considered, and the fastening bolt 9 is configured and arranged on the pressing plate 8 when the fixing device is produced, thereby facilitating the electric power operation of operators at a later stage.
