Abstract
The invention relates to a tool for installing or erecting lines or cables, particularly relates to a wire lifting tool for high-tension transmission line ground wires. The existing high-tension line ground wire lifting and erecting method is complex in operation, long in operating time and uncertain in working and the like. An upward carrying wire lifting trolley comprises a pulley mechanism, a tightening rope and an endless chain lever block; two ends of the tightening rope are connected with two ends of a ground wire preformed armor rod winding layer; the ground wire can be erected at a target position after wire winding operation through the tightening rope. The upward carrying wire lifting trolley has the advantages of simplifying high-tension line ground wire installing and erecting operation, greatly reducing operation time, enabling the ground wire preformed armor rod winding layer to be installed in place through operation for one time and being simple in design, easy to achieve, low in manufacturing and maintenance cost, applicable to various working occasions such as line installation and erection and wide in popularization and application prospect.
Description
Technical field
The present invention relates to a kind of for installing, the instrument of overhead transmission line or cable, be specifically related to the Line tool of carrying of a kind of ultra-high-tension power transmission line ground wire and optical cable.
Background technology
While setting up ultra-high-tension power transmission line, need to install preformed armor rods and strain clamp additional being set up in the additional ground wire of electric tower cross-arm.Existing method of operation is generally: first, operating personnel are according to the installation site of field wiring situation estimation preformed armor rods and strain clamp; Secondly, operating personnel use special spiral shell button instrument to complete preformed armor rods and strain clamp installation; Finally, ground wire is inserted into electric tower cross-arm place.In installation process, the stressing conditions due to preformed armor rods and strain clamp and ground wire is comparatively complicated at the scene, and after setting up, the position of preformed armor rods and strain clamp is usually offset.If after ground wire has set up, there is relatively large deviation in the estimation of discovery preformed armor rods and strain clamp and installation site and target location, need to ground wire be dismantled and be moved to operating desk from electric tower cross-arm, again ground wire is inserted into electric tower cross-arm after readjusting preformed armor rods and strain clamp position.Existing method of operation complex steps, comparatively consuming time, even if skilled craftsman operates, the conservative estimation of its one-stop operation time is at least 4 hours.In addition, existing method of operation need to be estimated the installation site of preformed armor rods and strain clamp, needs operating personnel to possess the practical work experience compared with horn of plenty.In existing high-tension line there is the problems such as complicated operation, activity duration be long in carry line and the erection method of ground wire, and have certain work uncertainty.The upper anti-of high-tension line ground wire that proposes a kind of handled easily carried the Line tool, is problem demanding prompt solution in current installation, built on stilts and maintenance high-tension line.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of shouldering on simple in structure, convenient and practical and carry line coaster, on this, shoulder and carry line coaster and can guarantee after ground wire sets up, the part that preformed armor rods and strain clamp are installed is accurately set up in target location, and reduction activity duration by a relatively large margin and reduce labour intensity.
For solving above technical problem, technical scheme of the present invention is:
In one, shoulder and carry line coaster, comprise the pulley mechanism and the tightening system that are fixedly installed on electric tower cross-arm; Wherein, pulley mechanism comprises pulley support and is arranged on the pulley in pulley support by rotating shaft; Tightening system comprises the rope connecting in turn
, cucurbit and rope
; Rope
be positioned at the groove of described pulley, rope
and rope
free end be fixedly connected with ground wire by knot that can be undone by a pull.
Concrete, described cucurbit is hand chain lever hoist.
Concrete, rope
for nylon rope, rope
comprise steel wire rope and nylon rope; One end of steel wire rope is connected with described cucurbit, and its other end is connected with nylon rope by U-shaped link.
Concrete, pulley mechanism is arranged on electric tower cross-arm top, and pulley mechanism is that on-fixed is connected or bolt connects with the connected mode of electric tower cross-arm.
The common composition of pulley mechanism, tightening system and the ground wire isosceles triangle vertical with electric tower cross-arm; Pulley mechanism is positioned at isosceles triangle vertex position, and ground wire forms the fixing base of length of isosceles triangle, and tightening system forms two waists of isosceles triangle, by cucurbit, tightening system is carried out to folding and unfolding to change the length of isosceles triangle two waists.
Beneficial effect of the present invention: the pulley mechanism that 1, is arranged on electric tower cross-arm top is shouldered the ground wire of carrying line coaster and carry on being and provided support, and has ensured to install overall working stability; 2, when pulley makes tightening system folding and unfolding, freely, protection tightening system is avoided wearing and tearing, extends tightening system useful life in motion; 3, the steel wire rope part of tightening system is positioned at pulley groove, is conducive to tightening system and carries out folding and unfolding when action, keeps the stable of its operation; 4, hand chain lever hoist is for device provides power, have volume little, from heavy and light, the feature such as simple to operate, easy to use; 5, tightening system two ends are fixedly connected with by knot that can be undone by a pull with the two ends of preformed armor rods winding layer on ground wire respectively, when site operation, can adjust at any time the position of two knots that can be undone by a pull according to the actual installation position of preformed armor rods winding layer, ensure that ground wire is inserted into after electric tower cross-arm, its preformed armor rods winding layer position can accurately be positioned at target location, if only use the one end in tightening system to be fixedly connected with and to propose line operation with ground wire, although can realize the anti-function of carrying line and overhead ground wire, the ground portion that adds preformed armor rods winding layer accurately cannot be set up in to target location; 6, the common composition of pulley mechanism, tightening system and the ground wire isosceles triangle vertical with electric tower cross-arm, has ensured to install overall stability.The present invention designs succinctly, easy to implement, make and maintenance cost lower, be applicable to various circuits and the workplace such as install, make somebody a mere figurehead, there is wide promotion and application prospect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of Fig. 1 left view.
Wherein, 1 pulley, 2 pulley supports, 3 ropes
, 4 cucurbits, 5 ropes
, 5-1 steel wire rope, the U-shaped link of 5-2,5-3 nylon rope, 6, ground wire, 6-1 preformed armor rods winding layer, 7 electric tower cross-arms.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 2, self-control pulley mechanism, its middle pulley 1 diameter of phi 280mm, pulley external diameter Φ 325mm, pulley rim width 37mm, pulley support 2 is that 2 block lengths are ∠ 45 × 45 × 5 angle steel of 100mm; The steel wire rope 5-1 part of tightening system is Φ 11mm steel wire rope, according to trigonometric function, in conjunction with lifting and the decline scope of the installation site of pulley mechanism, ground wire 6 target locations, ground wire 6, determines in tightening system and restricts
