Abstract

The invention discloses a simple climbing falling protector for an electric transmission line. The simple climbing falling protector is composed of a padlock and a speed difference protector; the speed difference protector is composed of a connecting ring, a speed difference protector shell and a safety belt; the padlock is composed of a hook, a spring tongue, a spring tongue clamp, a closed circular ring, a tongue pulling rope, an upper fixed pulley and a lower fixed pulley, the suspended end of the spring tongue and an arc spring tongue hook bill of the hook form a closed ring together to hold an iron tower glide tack, and a spring tongue hook at the right end of the spring tongue clamp can hook or release the suspended end of the spring tongue. The simple climbing falling protector has the two following advantages that use is convenient, the simple climbing falling protector can be hung on the iron tower glide tack or taken out easily, and an iron tower climbing worker can operate the falling protector conveniently without affecting the pole and tower climbing work of the iron tower climbing worker; effective protection can be provided for the iron tower climbing worker during pole and tower climbing, it is ensured that the worker does not loss effective protection during the work of going up and down a pole and tower, and falling accidents of the iron tower climbing worker during pole and tower climbing are prevented.

Description

Transmission line of electricity simply climbs catching device

Technical field

The present invention relates to power equipment, especially relates to a transmission line of electricity and simply climb catching device, it is a kind of for frame Empty transmission line of electricity is ascended a height the Special safety anti-falling tool that operation is used.

Background technology

With the fast development of electrical network, overhead transmission line is constantly built, is increased, the work of accordingly ascending a height of power worker The situation of industry will be significantly increased, as construction of line during construction and input post exercise line maintenance.Our province 500kV is defeated at present Electric line has reached more than 3000 kilometer, in all of steel tower, only less than being mounted with rail mounted iron tower falling-proof on 1% steel tower Device.In most work high above the ground, climbing steel tower personnel during ascending a height be without anti-falling protection.In overhead power transmission Circuit is ascended a height in operation, and steel tower personnel are because of a variety of causes for climbing（Such as strong wind, circuit rock, the job morale of itself etc.）Cause weight The heart is unstable very likely from falling from high altitude, personnel casualty accidentses occurs, causes unnecessary loss.

Content of the invention

It is an object of the invention to provide a kind of can effective protection climbing steel tower personnel safely, prevent from falling, safety is imitated The transmission line of electricity of beneficial high, easy to use, low cost simply climbs catching device.

The object of the present invention is achieved like this：

A kind of transmission line of electricity simply climbs catching device, including the speed difference being made up of connection ring, speed difference protector housing and seat belt Protector, the upper end of the connection ring that can rotate upwardly and downwardly is by lock pin and with speed difference device insurance, the speed difference protector housing of annular Lower end is flexibly connected, and seat belt is dish type and can extract out and withdraw, the lower end of seat belt is fixed on the seat belt hanging hole of connection ring In, it is characterized in that：Also include the extension being made up of coupler body, bullet tongue, bullet tongue card, closed circle, pull tab rope, upper fixed pulley and lower fixed pulley Lock, the lower end of coupler body is closed circle, is provided with a groove on the inside of the closed circle linkage section of coupler body with coupler body lower end, carries bullet Bullet tongue one end of spring is by playing bottom of the tongue hinge in groove, at closed circle, and the other end of bullet tongue is hanging, bullet The middle part of tongue card is by playing top of the tongue card hinge in groove, and the free end for playing tongue can be with the arc bullet tongue hook-bill of coupler body A closing ring body is collectively formed, the steel tower foot nail in closed-loop body is embraced, the bullet tongue grab for playing tongue card right-hand member can be hooked or de- The free end for playing tongue being opened, tongue is played as coupler body anti-drop device, plays tongue card and play tongue device as fixing；In coupler body and coupler body lower end Fixed pulley and lower fixed pulley is respectively equipped with the outside of closed circle linkage section, and the upper end of pull tab rope is fixed on the free end for playing tongue On, the lower end of pull tab rope from groove by rear, bypass hanging after upper fixed pulley and lower fixed pulley, pull tab again successively from top to bottom Restrict for packing up bullet tongue, the upper end of seat belt is fixed on closed circle.

The present invention is made up of padlock and speed difference protector, and the coupler body width in padlock follows closely width slightly larger than foot, climbs during use Climbing steel tower personnel only need to make bullet tongue free end depart from the arc bullet tongue hook-bill of coupler body, hook with the left end of thumb press bullet tongue card Body is suspended to steel tower foot and nails on, and unclamps thumb during extension, and bullet tongue is upspring again and resetted, and steel tower foot nail i.e. in coupler body and plays tongue institute Do not fall out in the closed-loop body of composition, the free end of pull tab rope is tied up on the belt of climbing steel tower personnel, when coupler body is removed, only Pull tab rope is pulled, is played and coupler body by tongue is packed up, is removed, repeatable operation, complete climbing.Connection ring is connected with seat belt, so speed Difference protector can guarantee that the personnel's climbing of climbing steel tower will not be fallen to ground when slipping out of the hand, and play protection climbing steel tower personal security Effect, it is ensured that be unlikely to during climbing steel tower personnel climbing to fall to death because falling, traumatic injury, so as to take precautions against falling risk.This Bright be made up of high-strength aluminum alloy, rotating junction divides connection reliable, lightly nimble, safety durable.

Therefore, the present invention has following two features：

1st, the present invention is easy to use, it is easy to can just be suspended to steel tower foot and nail on or take out, convenient climbing steel tower human users, not shadow Ring climbing steel tower personnel and climb pole tower operation；

2nd, when the present invention can climb shaft tower for climbing steel tower personnel, effective protection being provided, it is ensured that has not lost during pole tower operation up and down , when preventing from climbing steel tower personnel's rod-rising tower, there is falling accident in effect protection.

Therefore, the present invention have can effective protection climbing steel tower personnel safely, prevent from falling, safety benefit is high, use The convenient, advantage of low cost, is a kind of instrument of delicate structure.
