Abstract
A kind of for insulator cradle for replacing insulator string of power transmission line Novel special triangular, solve transmission circuit insulator string replacing labour intensity large, cause the problem of time delay power transmission, it is characterized in that arranging a positive triangle tripod 3 of top band annulus, go to the bottom at the positive triangle tripod 3 of top band annulus and garden treasured screw 4 is set, upper top connection one enclosed annulus 2, arrange in enclosed annulus 2 other end and be connected with end band ring half-pass button screw rod, the present invention has and can realize alleviating intensity of workers, easy to operate, speed is fast, safe and reliable, the advantage that effect is high, be adapted to transmission circuit insulator string change, 220KV-110KV transmission line changes the special use of insulator string institute adapted bottle-holding rack.
Description
Technical field
The present invention is specifically related to a kind of for the special tripod of insulator cradle for replacing insulator string of power transmission line.Belong to the technical field that electric machinery specific purpose tool makes, be adapted to transmission circuit insulator string and change, 220KV-110KV transmission line changes the special use of insulator string institute adapted bottle-holding rack.
Background technology
For guaranteeing power circuit power supply reliability, for a long time, electric power system, according to administrative transmission line region, carries out the comprehensive regulation of circuit targetedly, comprises the transmission line insulator flashover caused due to filthy problem here and causes circuit breaking accident.Associated production enterprise proposition circuit Composite (pass by line unification and be replaced by silicon rubber synthetic insulators by all power transmission lines for this reason, and carry out RTV spray painting after the larger glass insulator of replacing creep distance is adopted to line tension part), and because the bottle-holding rack tripod screw rod operating aluminium alloy jig adapted used fails to insert smoothly in jig fixing hole in replacing strain insulator string process, cause the invisible increase of intensity of workers.The more important thing is that shift fails completing task on time task, time delay power transmission happens occasionally, and system power supply reliability is had a strong impact on.One of reason, strain rod tower insulator string and the angular deviation of tower body horizontal vertical large; Reason two, bottle-holding rack tripod screw rod and bottle-holding rack deviation angle integral, can not flexible transformation angle, can only extremely push away hard holder during human users, but often things turn out contrary to one's wishes.Screw rod is failed directly to insert in jig fixing hole.Not yet have one to alleviate personnel labor intensity at present, Novel work utensil simple and efficient to handle occurs, also there are no relevant bibliographical information and record.
Summary of the invention
Object of the present invention is exactly that more than customer service is not enough, provides and can realize alleviating intensity of workers, simple and practical, easy to operate, safe and reliable, and the one of successful is used for the special tripod of insulator cradle for replacing insulator string of power transmission line.
The present invention adopts following technical scheme to realize: described one is used for the special tripod of insulator cradle for replacing insulator string of power transmission line, it is characterized in that arranging a positive triangle tripod 3 of top band annulus, go to the bottom at the positive triangle tripod 3 of top band annulus and garden treasured screw 4 is set, upper top connection one enclosed annulus 2, arranges in enclosed annulus 2 other end and is connected with end band ring half-pass button screw rod.The special tripod of bottle-holding rack, comprise precious 2, the screw in φ 12 garden, interior angle 60 degree of length of sides are 15CM, and brandreth one end band φ 18 annulus of positive gable-top end band φ 16 annulus, length is 15CM half-pass button φ 12 screw rod one, enclosed φ 18 annulus one.One of the present invention is used for insulator cradle for replacing insulator string of power transmission line Novel special triangular, is nested by enclosed annulus 2 three ring and carries out strict pull test during production.
One of the present invention is used for the special tripod of insulator cradle for replacing insulator string of power transmission line, has and can realize alleviating intensity of workers, simple and practical, easy to operate, safe and reliable, the advantage of successful.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of for the special tripod structure figure of insulator cradle for replacing insulator string of power transmission line.
Accompanying drawing 2 is a kind of for the special tripod exploded view of insulator cradle for replacing insulator string of power transmission line.
In figure: 1. end band ring half-pass button screw rod, 2. enclosed annulus, the 3. positive triangle tripod of top band annulus, the 4. precious screw in garden.
Embodiment
Implement clever below in conjunction with accompanying drawing to do the present invention and further believe explanation, one is as shown in Figure 2 used for the special tripod of insulator cradle for replacing insulator string of power transmission line, for single-piece makes, comprise band lead screw 1, enclosed ring 2, the positive tripod 3 of top band. the precious screw 4 in garden, one end band half-pass button φ 14 screw rod, long 15CM; Top φ 16 annulus is rolled up weldering by φ 10 round steel and is formed positive tripod, hack lever is φ 14 round steel, long 15CM, it is 60 degree of positive tripods 3 that φ 18 enclosed ring is formed in enclosed ring 2, band angle, top by the weldering of φ 10 round steel volume, one is as shown in Figure 1 used for insulator cradle for replacing insulator string of power transmission line Novel special triangular, vibrational power flow is for arranging a positive triangle tripod 3 of top band annulus, go to the bottom at the positive triangle tripod 3 of top band annulus and garden treasured screw 4 is set, upper top connection one enclosed annulus 2, arranges in enclosed annulus 2 other end and is connected with end band ring half-pass button screw rod.Owing to being ring structures, screw rod all around operates and does not limit by support point, handles very skillfully, and therefore can reach anticipation object.
