Or maintenance, ensures the unimpeded of power transmission and transformation line with this, falling proof device is that a kind of safety being applied to work high above the ground process is protected
Protecting equipment, it is by being fixed on the steel constructions such as electric power line pole tower, substation framework, portal frame and the architectural dragline of eminence,
Forming together with catching device, be now widely used on electric power line pole tower, the overall principle of Guide Rail Design is, former not changing
There is iron tower structure, do not affect circuit properly functioning, do not affect workman under the principle of normal operation, carry out the layout of reasonable benefit/risk,
Make more safe and reliable the moving on shaft tower of workman, prevent the generation of falling from high altitude accident.And the interior use of industry at present is anti-fall
Device great majority exist, and structure is complicated, the excessively heavy safety that be difficult to ensure that use during unreasonable with structure design of volume,
And the problem and shortage such as the translational speed greatly reducing operator.Therefore, for the problems referred to above, a kind of transmission line of electricity is proposed
Anti-fall device.
Utility model content
Having problems for above-mentioned prior art, this utility model provides the anti-fall device of a kind of transmission line of electricity, is created by employing
" Dual-locking device " structure, locking is stable, and efficiently solves because tilting operation tenesmus rocking tendency excessive and clash into other
Object and the accident that causes, good reliability, solve problem present in background technology.
For achieving the above object, the technical solution adopted in the utility model is: the anti-fall device of a kind of transmission line of electricity, including steel band
And it is wrapped in the ratchet-gear wheel that steel band is peripheral；Described ratchet-gear wheel is arranged at the inside center of shell, and between shell and ratchet-gear wheel
Ratchet is set；Described ratchet runs through shell one end by steel wire cable, and ratchet is connected to upper hook by steel wire cable；Institute
The one end stating shell is connected to nylon kernmantle, and the side of nylon rope arranges hook.
Further, distance 3 5cm between described ratchet-gear wheel and shell, and ratchet-gear wheel is the jagged circular knot of boundary zone
Structure.
Further, described ratchet is fixed on the inwall of shell, and ratchet is circular arc.
Further, 2/3rds of a diameter of nylon kernmantle diameter of described steel wire cable.
Further, described steel wire cable is a kind of with the steel wire cable being automatically adjusted length device.
The beneficial effects of the utility model are: the anti-fall device of this kind of transmission line of electricity is the compactest, easy to operate, and safety coefficient is high,
Good reliability, uses " Dual-locking device " structure of original creation, and locking is stable, and efficiently solves because inclination operation tenesmus is waved
The accident that amplitude is excessive and clashes into other objects and causes, can lock dropped object limiting apart from interior fast braking, be suitable for defeated
In electric line, accessory lifting and replacing, protect the life security of ground handling operator and hung the damage of workpiece object, can be effective
The protection life security of workmen and the damage of hanging object, can play important during the dangerous repairing of power system
Effect, be suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
In figure: 1, lower draw-bar, 2, steel wire cable, 3, ratchet, 4, steel band, 5, ratchet-gear wheel, 6, shell, 7, nylon
Kernmantle, 8, upper hook.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear,
It is fully described by.Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
Based on the embodiment in this utility model, the institute that those of ordinary skill in the art are obtained under not making creative work premise
There are other embodiments, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, the anti-fall device of a kind of transmission line of electricity, including steel band 4 and the ratchet-gear wheel 5 that is wrapped in steel band 4 periphery；
Described ratchet-gear wheel 5 is arranged at the inside center of shell 6, and arranges ratchet 3 between shell 6 and ratchet-gear wheel 5；Described ratchet 3
Run through shell 6 one end by steel wire cable 2, and ratchet 3 is connected to hook 8 by steel wire cable 2；Described shell 6
One end be connected to nylon kernmantle 7, and the side of nylon kernmantle 7 arranges hook 8.
As optimisation technique scheme of the present utility model: distance 3 5cm between described ratchet-gear wheel 5 and shell 6, and ratchet-gear wheel
5 is the jagged circular configuration of boundary zone；Described ratchet 3 is fixed on the inwall of shell 6, and ratchet 3 is in circular arc；Institute
State steel wire cable 2 a diameter of nylon kernmantle 7 diameter 2/3rds；Described steel wire cable 2 is a kind of with being automatically adjusted
The steel wire cable 2 of length device.
Steel band 4 in use, is first tied up to the position of protection rope by this utility model, and steel band 4 is applied in the inside of shell 6,
When the length of user sensation steel wire cable 2 is long or too short, can by regulation be positioned at steel band 4 surface ratchet-gear wheel 5 and
The length of the chimeric steel wire cable 2 that stretches of ratchet 3, upper hook 8 is enclosed within electric wire by user, works out rope 7 by nylon
Being connected to shell 6, shell 6 is linked together by steel wire cable 2 with lower draw-bar 1, and lower draw-bar 1 is enclosed within the belt of user,
Once nylon kernmantle 7 ruptures, and lower draw-bar 1 is immediately by the weight transmitting of user to steel band 4, thus realizes anti-fall merit
Can, at utmost protect the operation safety of user.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and not
In the case of deviating from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore,
