Abstract
The utility model relates to an electric communication pole tower climbing anti-falling device. The prior high-altitude anti-falling device adopts a bulky disc-shaped cam or an eccentric wheel as a braking piece, and the weight of a complete set of the high-altitude anti-falling device reaches to 4 KG; moreover, a steel strand and a trunking are under direct friction; therefore, the steel strand and the trunking which are metalworks are easy to cause a blast injury to a person when a falling accident occurs; moreover, because the frictional coefficient between metalworks is small, braking is difficult to realize or braking distance is very long; therefore, the anti-falling device has poor safety. Through adopting the technical proposal according to which a portable lever type cam brake lever is adopted and a high-density rubber pad is arranged between the steel strand and the trunking, the electric communication pole tower climbing anti-falling device overcomes the disadvantages; moreover, the weight of the entire anti-falling device is only 0.7 KG.
Description
Technical field
The utility model relates to the anti-fall technology of ascending a height, particularly a kind of power communication shaft tower anti-fall device of ascending a height.
Background technology
200620099229.6 patent disclosure a kind of steel strand wires formula high-altitude anti-fall device, because it adopts heavy discoid cam or eccentric wheel as brake component, a whole set of high-altitude anti-fall device weighs 4 kilograms, the work high above the ground personnel will draw it and move up and down, easy consumption causes tired than many-body force, increase work high above the ground danger; Lack liner between these high-altitude anti-fall device steel strand wires and the wire casing, steel strand wires and wire casing directly rub, quicken to wear and tear between them, reduce service life greatly, and once the tenesmus accident takes place because steel strand wires and wire casing are metalwork, to personnel's wound that easily impacts, coefficient of friction is difficult to for a short time to realize braking that the braking distance needs are very long in other words between the metal in addition, so this device poor stability.
Summary of the invention
The utility model purpose provides that a kind of safety is light, the power communication shaft tower of flexible braking, long service life is ascended a height anti-fall device.
The utility model technology contents is a kind of power communication shaft tower anti-fall device of ascending a height, and comprises steel strand wires, wire casing, brake component, and it is characterized in that: brake component is a lever cam brake bar, is furnished with the high density rubber blanket between steel strand wires and wire casing;
The forearm length of lever cam brake bar is less than the back arm lengths;
The forearm of lever cam brake bar is 1 to 2 with the postbrachium length ratio;
The high density rubber blanket is the U type;
Be furnished with torsion spring on the postbrachium of lever cam brake bar;
Directive wheel is equipped with in wire casing inboard, lever cam brake bar forearm top.
Good effect of the present utility model is because it adopts lever cam brake bar structure, the a whole set of power communication shaft tower anti-fall device of ascending a height has only 0.7 kilogram, the sixth that almost has only aforementioned patent, alleviated the weight of the anti-fall device of ascending a height greatly, make things convenient for the work high above the ground personnel to carry, improved security; Be furnished with the high density rubber blanket between steel strand wires and wire casing, prolonged the anti-fall device life-span of ascending a height, once the tenesmus accident takes place because high density rubber blanket buffering is arranged between steel strand wires and wire casing, to personnel's wounds that can not impact, and braking distance is also lacked.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 vertical view.
1-wire casing among the figure, 2-high density rubber blanket, the 3-steel strand wires, the 4-directive wheel, the 5-torsion spring, the 6-bearing pin, 7-lever cam brake bar, 8-safety is with holes.
The specific embodiment
The forearm length of lever cam brake bar 7 is meant the horizontal range of bearing pin 6 centers to lever cam brake bar front end and steel strand wires 3 contact points, and back arm lengths is meant safety 8 centre distances with holes on bearing pin 6 centers to lever cam brake bar right side.
With lie in the work high above the ground personnel on one's body safety belt penetrate in the safety with holes 8 on lever cam brake bar 7 right sides and fasten, when the work high above the ground personnel upwards climb from ground, the a whole set of power communication shaft tower anti-fall device of ascending a height moves up under the safety belt traction, because package unit has only 0.7 kilogram, be installed on inboard directive wheel 4 guide effects of lever cam brake bar forearm top wire casing again, package unit can be free and relaxed moves up and can be not stuck with the work high above the ground personnel in addition.
Torsion spring 5 effect is to guarantee that the forearm of lever cam brake bar 7 contacts with steel strand wires 3 all the time or keeps minimum clearance on lever cam brake bar 7 postbrachiums.
When the work high above the ground personnel unfortunately fall in the high-altitude, safety belt can center on bearing pin 6 to lower swing by pull lever formula cam brake bar 7 postbrachiums, lever cam brake bar 7 forearms upwards push against steel strand wires 3 forward thereupon, steel strand wires 3 push against with U type high density rubber blanket 2 and realize flexible braking, because steel strand wires 3 and 1 of wire casing have high density rubber blanket 2 to cushion, to personnel's wound that can not impact.Fall with 100 kilogram weights of objects test of many times high-altitude on the utility model, its braking distance is no more than 30 centimetres, is crowned with complete success.
Claims (6)
