Abstract
The utility model discloses an insulating single-column ladder including a hollow column shaped pipe body, the pipe body is provided with ladder rods vertical to the pipe body in left-right symmetry along the axial direction, and four hanging rings are circumferentially and uniformly distributed around the top end of the pipe body. The pipe body of the insulating single-column ladder is provided with the ladder rods vertical to the pipe body in left-right symmetry along the axial direction for people to climb, the ladder rods are provided with antiskid grooves to improve the safety, and the four hanging rings are arranged at the four corners of the top end of the ladder to realize the function of the connection with insulation ropes; meanwhile, the connection parts of the hanging rings are capable of performing 360-degree rotation via movable blocks to balance the nonuniform force bearing of insulation pull wires at the four sides. In addition, the middle metal joints of the insulating single-column ladder are in a threaded connection manner and are provided with four fixing circular rings, and temporary pull wires can be increased if necessary.
Description
Technical field
The utility model relates to insulation single-column ladder.
Background technology
In prior art, at transmission line, process wire defect in shelves, often adopt insulated flexible ladder to be suspended on wire, personnel climb to the wire fault location, then are wound around or study for a second time courses one has flunked the method such as preformed armor rods repairing by aluminium wire, 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.
The utility model content
Technical problem to be solved in the utility model 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 utility model adopts following technical scheme: a kind of insulation single-column ladder, the pipe shaft that comprises open column shape, 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, is provided with 360 degree rotational structures between described movable block and pipe shaft.
Preferably, described pipe shaft comprises at least two elementary sections, between adjacent two elementary sections, by metal joint, is threaded.
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 pipe shaft of the utility model insulation single-column ladder 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 respectively arranged, 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 utility model is:
1. this insulation single-column ladder can effectively be filled up wire in shelves, after checking, can not hang the neutral that insulated flexible ladder carries out operation, has increased the methods of live line working emergency treatment defect.
2. this insulation single-column ladder 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. this insulation single-column ladder 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
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the utility model structural representation one;
Fig. 2 is the utility model structural representation two.
Embodiment
Fig. 1 and Fig. 2 show the concrete structure of the utility model insulation single-column ladder.
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, is provided with 360 degree rotational structures between described movable block and pipe shaft.Described pipe shaft comprises at least two elementary sections, between adjacent two elementary sections, by metal joint 4, is threaded.。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 utility model 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.
