Description

With the aluminium alloys hanging ladder of Self-enclosing structure
technical field:
The utility model relates to a kind of power overhead network maintenance tool, particularly relates to a kind of aluminium alloys hanging ladder with Self-enclosing structure.
background technology:
Along with electric power plays an increasingly important role in economical production, many transmission lines of electricity arbitrarily cannot carry out interruption maintenance, in lead wire and earth wire, hanging ladder operation is an elemental operation mode of livewire work, as: charged repairing wire, removing lead wire and earth wire hang foreign matter etc.It can get rid of circuit major safety risks when charged, and insulating ladder head is absolutely necessary one of instrument.But original ladder head, without the problem of blocking device, makes the upper operating personnel of ladder in operation process, there is very large potential safety hazard.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides that a kind of structure is simple, easy to use, be connected firmly low and that safety the is good aluminium alloys hanging ladder with Self-enclosing structure.
The technical solution of the utility model is:
A kind of aluminium alloys hanging ladder with Self-enclosing structure, comprise two vertical rods, described two vertical rods connect into ladder shape by spaced cross bar, the upper end of described two vertical rods is respectively arranged with hook, the all hinged latch plate of the blind end linked up with described in each, the openend linked up with described in each is provided with a limiting plate, spring is provided with between described latch plate and hook, one end of described latch plate is normally closed in described limiting plate under described spring action, the other end of described latch plate is provided with outstanding rope, the lower end of described outstanding rope falls to ground, controlled by operating personnel, described hook is made up of insulation materials.
Be provided with connecting rod between the other end of two described latch plate, the upper end of described outstanding rope is fixedly connected with described connecting rod; Described limiting plate is L shape or U-shaped.
Described vertical rod and cross bar are made up of insulation materials, and the shape of described hook and size and cable match, and described spring is extension spring, stage clip or torsion spring.
The beneficial effects of the utility model are:
1, the utility model is in livewire work, adds the safety of operation, the simplicity of operation, and the technological gap of uncontrollable hook place, ground blocking device when having filled up hanging ladder operation.
2, the utility model is designed by mechanical linkage transmission mechanism and spring assembly, control blocking device, take the operational method of terrestrial operation blocking device, fill up the technological gap of such instrument domestic in safety applications, this tool combinations to the Quick overhaul of circuit, safeguard and provide reliable guarantee.
3, the utility model structure simple, easy to use, be connected firmly low and safety good, be mainly used in 110 kilovolts and above transmission line of electricity and transformer station's wire, busbar overhaul operation, for major defects such as the lead wire and earth wire damages that circuit occurs, this instrument is a necessary class instrument, therefore range of application is especially extensively and to raising operational security, play very important effect, economic benefit is obvious.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the aluminium alloys hanging ladder with Self-enclosing structure;
Fig. 2 is the sectional side view with the aluminium alloys hanging ladder of Self-enclosing structure shown in Fig. 1.
detailed description of the invention:
Embodiment: see in Fig. 1 and Fig. 2, figure, 1-vertical rod, 2-cross bar, the outstanding rope of 3-, 4-connecting rod, 5-spring, 6-latch plate, 7-links up with, 8-cable, 9-limiting plate.
Aluminium alloys hanging ladder with Self-enclosing structure comprises two vertical rods 1, two vertical rods 1 connect into ladder shape by spaced cross bar 2, the upper end of two vertical rods 1 is respectively arranged with hook 7, wherein: all hinged latch plate 6 of blind end of each hook 7, the openend of each hook 7 is provided with a limiting plate 9, spring 5 is provided with between latch plate 6 and hook 7, one end of latch plate 6 is normally closed in limiting plate 9 under spring 5 acts on, the other end of latch plate 6 is provided with outstanding rope 3, the lower end of outstanding rope 3 falls to ground, is controlled by operating personnel; Hook 7 is made up of insulation materials.
Preferred version: be provided with connecting rod 4 between the other end of two latch plate 6, the upper end of outstanding rope 3 is fixedly connected with connecting rod 4, now adopts one to hang and restricts; Limiting plate 9 is L shape or U-shaped.
Vertical rod 1 and cross bar 2 are made up of insulation materials, and shape and size and the cable 8 of hook 7 match, and spring 5 is extension spring, stage clip or torsion spring.
During use, operating personnel pull outstanding rope 3 downwards, one end of latch plate 6 is thrown off in limiting plate 9, the open at its lower end of hook 7, hook 7 just can hang on cable 8 smoothly, unclamps outstanding rope 3, under the effect of spring 5, the other end of latch plate 6 closes in limiting plate 9, makes the lower end closed of hook 7, effective anti-locking hook.This tool combinations to the Quick overhaul of circuit, safeguard and provide reliable guarantee.
The above is only preferred embodiment of the present utility model, not does any to the utility model
Pro forma restriction, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
