Description
Technical field
The utility model relates to the technical field of power transmission sequence hoisting operation, relates in particular to 2 lifting instruments of a kind of overhead ground wire ratchet wrench of power transmission sequence hand-type.
Background technology
At present; Installation for the power line tower overhead ground wire; The workmen is in order to remove overhead ground wire from pulley block; After the ground wire suspension clamp is installed, utilize the connection gold utensil that ground wire is fixed on ground wire hanging point place, the method for employing is that installation personnel carries out method pickaback, and this method pickaback exists following problem in real work:
(1) because workmen standing place on tower is not the optimum position that is fit to pickaback, strength can not be given full play in process pickaback, has certain difficulty with the correct position that makes ground wire can reach installation pickaback.
(2) pickaback during overhead ground wire because overhead ground wire weight is big, many work high above the ground personnel cause the lumbar strain phenomenon in operation process.
(3) pickaback overhead ground wire because the height shouldered of effect of ground line tension is high more; Tension force is big more; Needed strength is also just big more, a lot of big ground wire operations of span, and the operating personnel does not shoulder the position and from takeing on to come off the situation on ground, ground wire whereabouts takes place owing to ground wire takes place strength inadequately.
(4) this operational method needs two people's coordinating operations on the tower, because standing place and height is different, inharmonious, the inefficiency of cooperatively interacting, labour intensity is big, potential safety hazard is many.
Summary of the invention
For solving overhead ground wire the practical problem that exists is installed; The utility model provides a kind of overhead ground wire ratchet wrench hand-type 2 lifting instruments; Its simple and reasonable, esy to use, safe and reliable, suitable single operation on tower, the overhead ground wire line lifter of the low high efficiency of labour intensity.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
2 lifting instruments of a kind of overhead ground wire ratchet wrench hand-type; Constitute by the lifter of channel-section steel two ends connection and the jig of channel-section steel middle part setting; Described jig is the convex structure that is enclosed within on the symmetry angle steel arranged side by side; The limit, convex structure two ends of jig is provided with fixed screw, and the concave slot of jig convex structure is provided with jackscrew.
2 lifting instruments of a kind of overhead ground wire ratchet wrench hand-type; Said lifter is made up of crane boom, coiling steel pipe, ratchet, ratchet, spanner, the fixedly screw mandrel of crane boom, steel wire rope, suspension hook; Crane boom is a trench structure, and the crane boom bottom land links to each other with channel-section steel through connecting screw, and the crane boom trough rim is provided with wind the line steel pipe and fixing screw mandrel; Said coiling steel pipe is provided with the coiling hanging hole of steel wire rope, and steel wire rope is linked to each other with fixing screw mandrel through suspension hook by the coiling steel pipe; Said coiling steel pipe one end is provided with ratchet, ratchet and ratchet engagement; The said coiling steel pipe other end is provided with the spanner that cooperates with ratchet spanner.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
2 lifting instruments of a kind of overhead ground wire ratchet wrench hand-type in the time of can making the workmen carry out work high above the ground, need not used pickaback; Single independence just can be accomplished; Avoided the waist injury in the work progress, the standing part of this instrument and cross-arm makes full use of the original structure of double hanging point angle steel; When stressed, avoid the damage to cross-arm, easy for installation, firm, stable; Also, can easily ground wire be risen to suitable installation site because of having shortened suspension centre to the distance of lifting by crane thing, the jig that this lifter adopts can according to the in-plane of lead cross-arm hanging point angle bar install adapt to wide; This lifter adopts two ends to be fixed with two lifting devices; Make things convenient for the lifting and the fixed installation of ground wire, the lifting partial design of this lifter adopts ratchet to be automatically locked, and that suspension clamp is connected gold utensil is convenient and swift when hanging point is installed removing the ground wire coaster.This instrument has characteristics such as advantages of simple, safe and reliable, operating efficiency height.
