Abstract

The invention discloses a high-voltage aerial work elevator. The elevator comprises a pulley, a hand-operated arm and a main frame, wherein a connecting rope is wound around the pulley and a lifting hook is arranged at one end of the connecting rope; the main frame comprises a supporting rod, and pulley clamp plates are fixed at one end of the supporting rod; the pulley clamp plates comprises a left clamp plate and a right clamp plate, which are provided with symmetrical central holes; and the pulley and the pulley clamp plates are fixed through the hand-operated arm. According to the invention, the lifting hook is used for hanging the elevator on a high-tension cable where operations are required, the connecting rope connected with the lifting hook is wound around the pulley, a worker stands on a foot board, meanwhile a safety belt penetrates through a sleeve loop and is fastened tightly with the elevator, and the hand-operated arm is operated by hand to achieve the purpose of up-down movement by using the working principle of the pulley. The elevator is economical, suitable for use, time-saving and labor-saving, and has the advantages that the structure is simple, the operation is convenient, the potential safety hazard is reduced, and the work efficiency is improved.

Description

A kind of high pressure work high above the ground lift
Technical field
The present invention relates to a kind of lift, relate in particular to a kind of lift for the work high above the ground of electric power system high-tension line.
Background technology
In the electric power transmission industry field, the high-tension line work high above the ground is common work, in recent years along with the continuous rising of electric pressure, and the continuous employing of common-tower double-return road ultra-high-tension power transmission line and extraordinary tower, exhaling of transmission line claims height and band to hang down more and more higher apart from ground, general in the past throwing extension highly is 25 meters, modern extra high voltage line can reach 50 meters-60 meters height, circuit overhauls in the high-altitude, change the closely-spaced rod of circuit, A, B, C is separately during device such as rod, the staff generally adopts about traditional rope ladder, rope ladder is subjected to the influence of strong wind weather in the air easily at height, make the staff not move up and down effectively, personal safety is on the hazard.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate, economic and practical high pressure work high above the ground lift.
The technical solution used in the present invention is:
A kind of high pressure work high above the ground lift, it is characterized in that: comprise pulley, hand arm and body frame, be wound with connection cord on the pulley, connection cord one end is provided with suspension hook, body frame comprises support bar, and support bar one end fixedly has the pulley clamping plate, and described pulley clamping plate comprise left clamping plate and right clamping plate, left side clamping plate and right clamping plate are provided with the centre bore of symmetry, and pulley and pulley clamping plate are by hand arm clamping.
Described lift also comprises alignment pin.
Be provided with a plurality of pin-and-holes around the described right clamping plate centre bore.
Described pulley right flank is provided with a plurality of alignment pin grooves, and alignment pin passes pin-and-hole and is absorbed in the alignment pin groove.
Described post upper also is provided with the safety belt running-on.
Described pedal center is provided with the rope hole, and connection cord passes pedal rope hole.
Described body frame adopts aluminum alloy materials.
Described pin-and-hole is consistent with the alignment pin groove fit.
The present invention utilizes suspension hook lift to be hung on the high-voltage line that needs operation, pulley is wound in the connection cord of connecting shackle, the staff stand on the pedal, it is solid simultaneously safety belt to be passed running-on and lift bolt, the mobile phone tool shakes hand arm, utilize the principle of pulley to reach the purpose that moves up and down, further, anti-limited slip wheel and connection cord break away from, utilize more firm fixedly connected, simple in structure, easy to operate, economic and practical, time saving and energy saving of alignment pin, reduce potential safety hazard, increase work efficiency.
