Background

Urban residents centralize living and activity areas and are configured with basic domestic water, electricity and gas; in the electricity utilization aspect of residents, the residents are generally paved by erecting telegraph poles, and also paved in a deep-buried underground mode, and for cables which are erected by the telegraph poles, the cables are erected and fixed at the end parts of the telegraph poles by using brackets; because various urban power utilization types require different types of cables, namely high-voltage cables, weak-current cables and signal cables, the cables are erected on telegraph poles through brackets, and therefore the different types of cables are laid in a classified manner through the brackets arranged up and down;

the power consumption requirements are different, so that the types of cables are different, some cables are bare aluminum wires, and the surfaces of some cables are coated with insulating layers; when the cable is erected, the cable between two telegraph poles cannot be in a stretched state, the cable between the two telegraph poles needs to be ensured to sag, the three forces of the tension of the two telegraph poles to the cable and the self weight of the cable are balanced, any two of the three forces cannot be on the same straight line, but the upper cable and the lower cable need to be considered to be out of contact; the bare cables have extensibility, the sag amplitude between the two cables is gradually increased for a long time, particularly in hot summer, the extensibility of the bare cables is more prominent, and at the moment, power maintenance personnel need to patrol and check the bare cables to avoid the condition that the sag amplitude of the cables is too large and the upper and lower bare cables are electrically contacted;

due to the structural design of the existing cable support, when the cable is tightened and the droop amplitude is reduced, the cable needs to ascend, climb to a support position point and be adjusted to be tightened, the trouble is caused to power maintenance personnel, the danger is increased during ascending operation, and meanwhile, the danger is increased when a body is close to a bare cable.

Therefore, the urban road cable fixing device is provided for solving the problems.

the arrangement of the position of the ejector rod 12 requires that the hexagonal prism 6 is completely sleeved by the inner hexagonal sleeve when the inner hexagonal sleeve is sleeved on the hexagonal prism 6, only then, the inner side wall of the inner hexagonal sleeve can effectively extrude the ejector rod 12 to enable the end part of the ejector rod 12 to be separated from the latch 15, and meanwhile, the hexagonal prism 6 is completely sleeved by the inner hexagonal sleeve, so that the extrusion stress area between the inner hexagonal sleeve and the hexagonal prism 6 is ensured, the slip between the inner hexagonal sleeve and the hexagonal prism 6 due to small contact area is prevented, and the side edges on the surface of the hexagonal prism 6 are removed and smoothened, so that the slip between the inner hexagonal sleeve and the hexagonal prism 6 is caused;

the end part of the ejector rod 12 is provided with a clamping plate 16 with a plurality of clamping feet 17, so that the stability between the ejector rod 12 and the clamping teeth 15 is improved, the abrasion of the end part of the ejector rod 12 caused by the clamping teeth 15 for multiple times is reduced, 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 fastening bolt 9 is tightened; because the cable fixing device is used for fixing cables, climbing operation is needed, various mounting tools and components are carried on the body, if the cables are fixed, the components fall off, firstly, the cables still need to fall to the ground and then prepared, or other auxiliary maintenance personnel climb to the height to feed the cables, the construction operation period is prolonged, and secondly, the components fall off and cause accidental injury to ground personnel, therefore, the end parts of the extrusion plates 23 are rotated on the rotating shaft 19, and the rotating shaft 19 passes through the rectangular grooves 21 of the L-shaped plates 20, namely, the extrusion plates 23 are connected to the supporting plate 7, the operation of field operation personnel is facilitated, and the possibility of uneven material preparation is reduced;

the grooves 18 on the upper and lower adjacent supporting plates 7 are arranged in a left-right staggered manner, so that when the cables in the grooves 18 sag, the sagging parts of the cables are distributed in a staggered manner, and the possibility of electrical contact of the sagging cables is reduced, and the cable laying device is suitable for cable laying spaces without external wind or gas flow, and the cables naturally cannot swing and contact; the extrusion plate 23 and the connecting plate 25 are arranged to tighten the cable with serious sagging, so that the possibility of electrical contact between the upper and lower adjacent cables is increased; by rotating the adjusting bolt 22, the adjusting bolt drives the extrusion press to approach towards the transverse plate 1, meanwhile, the extrusion plate 23 is pushed to approach towards the transverse plate 1, the fixed pulley 26 on the connecting plate 25 extrudes the cable, and the cable is gradually in a tightening state, so that 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 a person skilled in the art can consider that parts of the parts are operated by using insulating materials and the like; the anti-dropping plate 28 is arranged on the fastening bolt 9, so that the problem that the fastening bolt 9 accidentally drops or the problem that the materials of the fastening bolt 9 are uneven is also considered, when the fixing device is produced, the fastening bolt 9 is configured and installed on the extrusion plate 23, and the electric power operation of later-stage operators is facilitated.
