Abstract
The invention discloses an insulation single-column ladder which comprises a hollow columnar tube body. The tube body is provided with ladder rods which are perpendicular to the tube body in the axial direction in a left-right symmetry mode, and four hanging rings are evenly distributed at the top end of the tube body around the periphery. According to the insulation single-column ladder, the tube body is provided with the ladder rods which are perpendicular to the tube body and used for climbing in the axial direction in the left-right symmetry mode, the ladder rods are provided with anti-sliding grooves to improve the safety, the four direction of the top of the ladder are provided with four hanging rings respectively, the function of being connected with an insulation cable is achieved, meanwhile, all the hanging rings are connected with the tube body through movable blocks, and the connecting parts can make 360-degree rotation to balance the uneven stress of insulation drawing wires on the four sides. In addition, a middle metal joint of the insulation single-column ladder is in a threaded connection mode, four circular fixing rings are designed in the middle metal joint, and temporary drawing wires can be added when necessary.
Description
Technical field
The single-column ladder the present invention relates to insulate.
Background technology
In prior art, process wire defect in shelves at transmission line, often adopt insulated flexible ladder to be suspended on wire, personnel climb to the wire fault location, then by aluminium wire, are wound around or study for a second time courses one has flunked the method such as preformed armor rods repairing, make wire meet the requirement of transmission line service conditions.
But there is following defect in prior art:
1. in being arranged, the shelves of disconnected thigh process defect on wire, through checking the operation that can not hang rope ladder.
2. stand shelves or two people and above on same wire, through checking the operation that can not hang rope ladder.
Summary of the invention
Technical problem to be solved by this invention just is to provide a kind of insulation single-column ladder, applied widely, can be in the situation that can not hang soft ladder busywork and use.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of insulation single-column ladder, comprise the pipe shaft of open column shape, and described pipe shaft is symmetrically set with the terraced bar vertical with pipe shaft vertically, and described pipe shaft top is around circumferentially being evenly equipped with four links.
Preferably, described terraced bar is provided with antiskid groove.
Preferably, two neighbouring terraced distance between tie rods are 35cm.
Preferably, described link is connected with pipe shaft by movable block, between described movable block and pipe shaft, is provided with 360 degree rotational structures.
Preferably, described pipe shaft comprises at least two elementary sections, by metal joint, is threaded between adjacent two elementary sections.
Preferably, described pipe shaft above metal joint around circumferentially being evenly equipped with four clamping ringss.
Preferably, described pipe shaft and terraced bar are the epoxy resin integrated formed structure.
The insulate pipe shaft of single-column ladder of the present invention is symmetrically set with the terraced bar vertical with pipe shaft vertically for climbing, the ladder bar is provided with antiskid groove to improve fail safe, and in four directions, ladder top, four links are arranged respectively, realize the function be connected with insulation ropes, each link passes through movable block simultaneously, the connecting portion potential energy is done 360 degree rotations, inhomogeneous stressed with balance four sides insulation bracing wires.In addition, insulation single-column ladder intermetallic metal joint adopts the form that is threaded, and is designed with herein four clamping ringss, can increase temporary guy in case of necessity.
Thereby after the employing technique scheme, advantage of the present invention is:
1. this insulation single-column ladder can effectively be filled up wire in shelves, can not hang the neutral that insulated flexible ladder carries out operation after checking, and has increased the methods of live line working emergency treatment defect.
2. the single-column ladder that should insulate is simple to operate, has greatly alleviated the physical consumption (with respect to the climbing rope ladder) of the live line working personnel ladder stand period of the day from 11 p.m. to 1 a.m.
3. the single-column ladder that should insulate adopts the form of four side guys, has improved the fail safe of operation, and operating efficiency also is greatly improved.
4. this insulation single-column ladder has also improved the ability of live line working emergency treatment defect, has rationally solved the difficult problem in production reality, has further perfected hot line maintenance Work tool management system.
The accompanying drawing explanation
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation one of the present invention;
Fig. 2 is structural representation two of the present invention.
Embodiment
Fig. 1 and Fig. 2 show the insulate concrete structure of single-column ladder of the present invention.
It comprises the pipe shaft 1 of open column shape, and described pipe shaft 1 is symmetrically set with the terraced bar 2 vertical with pipe shaft vertically, and described pipe shaft top is around circumferentially being evenly equipped with four links 3.Described terraced bar 2 is provided with antiskid groove 20.Two neighbouring terraced bar 2 spacings are 35cm.Described link 3 is connected with pipe shaft by movable block 30, between described movable block and pipe shaft, is provided with 360 degree rotational structures.Described pipe shaft comprises at least two elementary sections, by metal joint 4, is threaded between adjacent two elementary sections.。Described pipe shaft above metal joint around circumferentially being evenly equipped with four clamping ringss 40.Described pipe shaft and terraced bar are the epoxy resin integrated formed structure.
Insulation single-column ladder of the present invention is equipotential people carrier.It realizes connecting by metal joint with multistage epoxy resin pipe, firm with four, top of ladder temporary guys after, personnel climb the processing of carrying out defect to wire from ground, thereby can be in the situation that can not hang soft ladder busywork and use.
