Abstract
A kind of transmission circuit insulator string maintenance transmission coaster, it is characterized in that, it is connected and is formed with semicircular arc-shaped lower snap ring Fig. 4 (7) make-up by a semicircular arc-shaped upper snap ring (5), wherein one end connection is hinged using axis pin (6), the other end is connected using T-shaped screw (10) and nut (11), and the T-shaped screw connecting pin is enable to tighten or loosen.The invention has the advantages that transmitting coaster can facilitate and be stably and fixedly mounted on insulator steel cap, easy to operate, dismounting is also easy to, and improves the safety factor of working at height；Shortening even is eliminated on line operating personnel and lifts Work tool distance, reduces labor intensity, improves working efficiency, breaks coaster hanging point delivery threshold, light and flexible, safe and reliable, and coaster overall weight is light, is convenient for carrying.
Description
Technical field
The invention belongs to ultra-high-tension power transmission line maintenance auxiliary tool, refer to transmission circuit insulator string maintenance when pair
The Work tool used carries out a kind of tool for being transferred to high-altitude.
Background technology
In high aerial completion, line maintenance tool kind is various for the service work of transmission line of electricity, need to be by this in maintenance
A little service kits are transferred to high-altitude.Currently, general transmission method is to use sling, steel wire set will transmit pulley suspension in insulator
Lower section (see Fig. 1), this construction method transmission rope hanging point is low, and operating personnel on circuit is needed to bend to incline, arduously lift ability
It completes Work tool to transmit, increases on-line operation personnel labor intensity, working efficiency is low, more with higher operating risk, nothing
It is all difficult to ensure by appropriate use for the personal safety or Work tool for being operating personnel, or even can therefore be delayed transmission line of electricity inspection
It repaiies, causes heavy economic losses.
Invention content
It is an object of the invention to overcome above-mentioned transmission coaster, proposes that one kind can shorten even to be eliminated on line and grasp
Make personnel and lift Work tool distance, for the purpose of reducing labor intensity, raising working efficiency, breaks coaster hanging point delivery threshold, gently
Just flexible, safe and reliable and special transmission coaster easy to operation.
Realizing the technical solution of above-mentioned purpose is：A kind of transmission circuit insulator string maintenance transmission coaster, feature of present invention
It is to be made of the semicircular arc-shaped lower snap ring make-up connection of a semicircular arc-shaped upper snap ring and one, wherein one end connection uses
Axis pin is hinged, the other end using T-shaped screw and nut connect, enable T-shaped screw connecting pin fasten or pine
It opens；It is equipped with concave the core of the card slot in the semi arch inner ring of the upper snap ring and lower snap ring and offers through screw on the core of the card slot
Hole is fixed with the core of the card that is semicircular arc-shaped and offering screw hole in the core of the card slot using slotted screw；
It is equipped with ladder-type trough on the entire semi arch ridge of upper snap ring, caulking groove is offered in ladder type trench bottom, divides in caulking groove
Cloth is inlaid with steel ball, and being equipped with a stop screw fastening in the tail end of caulking groove is used for backstop steel ball.
Upper and lower snap ring stall is ridden over using hoist rope in caulking groove on the steel cap of insulator when the present invention works
Steel ball on tool for transmitting carried out by hoist rope lifting.
The present invention can be adapted for different insulator steel caps by replacing different the core of the cards, to increase its extensive adaptation
Property.
The invention has the advantages that transmitting coaster can facilitate and be stably and fixedly mounted on insulator steel cap, grasp
Make simply, dismounting is also easy to, and improves the safety factor of working at height；Shortening even is eliminated operating personnel on line and lifts work device
Have distance, reduce labor intensity, improve working efficiency, breaks coaster hanging point delivery threshold, light and flexible, safe and reliable, coaster
Overall weight is light, is convenient for carrying.

See Fig. 1, Fig. 2, Fig. 3, a kind of transmission circuit insulator string maintenance transmission coaster, feature of present invention is, by one and half
The upper snap ring 5 of arc-shaped connects composition with semicircular arc-shaped 7 make-up of lower snap ring, and wherein one end connection is carried out using axis pin 6
Be hinged, the other end using T-shaped screw 10 and with pad nut 11 connect, enable the T-shaped screw connecting pin fasten or
It unclamps；It is equipped with concave the core of the card slot in the semi arch inner ring of the snap ring up and down and offers through screw hole on the core of the card slot,
The core of the card that is semicircular arc-shaped and offering screw hole 9 is fixed with using slotted screw 8 in the core of the card slot；
It is equipped with ladder-type trough on 5 entire semi arch ridge of upper snap ring, caulking groove is offered in ladder type trench bottom, divides in caulking groove
Cloth is inlaid with steel ball 4, and being equipped with a fastening of stop screw 3 in the tail end of caulking groove is used for backstop steel ball 4.
Upper and lower snap ring stall is ridden over into caulking groove on the steel cap of insulator 12 using hoist rope 2 when the present invention works
Tool for transmitting 1 is carried out by hoist rope lifting on steel ball in son.
The present invention can be adapted for different insulator steel caps by replacing different the core of the cards, to increase its extensive adaptation
Property.
The installation method for transmitting coaster is as above, and upper and lower snap ring 5,7 is stuck in the steel cap of insulator 12 in addition, fixed frame component is
Be equivalent to a closed fixture with the core of the card, first the core of the card 9 respectively with main body 5 and renovate 7 and be linked together with slotted screw 8, renovate 7
With main body 5 again with two axis pins 6, T-shaped screw 10, band pad nut 11 is attached as entirety.Wherein replace different the core of the cards 9
It can be adapted for different 12 steel caps of insulator (see Fig. 5).
