Abstract
The utility model relates to a replacing tool/appliance for double insulator strings, which is formed by sequentially connecting draw plates, retractable draw rods and a draw ring, wherein the draw plates adopt the following structure: an adjusting bolt is connected on the left ends of the two parallel plates, the right ends of the two parallel plates are connected with a fixing bolt, and the two parallel plates are provided with a plurality of adjusting holes; and the retractable draw rods adopt the following structure: a left rod and a right rod are respectively screwed on the left end and the right end of a cylinder, the left end of the left rod is suspended on the fixing bolt, and the right end of the right rod is suspended on the draw ring. The replacing tool/appliance is simple, practical and portable, and is a special tool for replacing double insulator strings of 220kV or below.
Description
Technical field
The utility model relates to the electric armour clamp maintenance and uses Work tool, especially for the specific purpose tool of changing 220kV and following double insulator string.
Background technology
Two insulator strings of power supply administration are changed at present, all are the manual labors of burdensome, generally use large-scale Work tool that it is changed, and in using large-scale Work tool process, are difficult for guaranteeing construction safety.Like this, exist the efficient of line maintenance work lower, the carrying of construction Work tool is difficulty, jeopardizes the bigger problem of potential safety hazard of construction.
The utility model content
The purpose of the utility model provides a kind of two insulator strings simple and practical, that be convenient for carrying and changes Work tool.
This novel purpose is achieved in that a kind of pair of insulator string replacing Work tool, is connected to form in order by arm-tie, scalable pull bar and draw ring; Pulling plate structure is: regulate bolt and be connected on the two parallel-plate left ends, be connected with a set bolt on the two parallel-plate right-hand members, and on two parallel-plates a plurality of adjustment holes arranged; Scalable Tiebar structure is: left bar and right bar are screwed in respectively on the left and right end of cylindrical shell; The left end cover of left side bar hangs on the set bolt, and the right-hand member cover of right bar hangs on the draw ring.
Above-mentioned draw ring is that an annulus or structure are: two otic placodes are arranged on the cuboid plate, be bolted on two otic placodes.
The beneficial effect of the utility model is: this is novel large-scale construction tool miniaturization, adopts the galvanized steel material to process, and it has and is convenient for carrying and puts, and is collapsible, also characteristics such as flexible.Can practice thrift construction equipment entrained when going out the construction of open-air high-altitude greatly, reduce high-altitude maintainer's workload.Can carry out 220kV and following double insulator string replacing, and can stretch, practice thrift work total time to a great extent, improved operating efficiency, reduced the carrying difficulty to different insulator string quantity.We believe that it bring very big facility can for later electrical production; In the near future, it will extensively utilization in electrical production obtains.
Description of drawings
Fig. 1 is this novel front view.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Fig. 1, Fig. 2 illustrate, and this pair insulator string is changed Work tool and connected to form in order by arm-tie 1, scalable pull bar 2 and draw ring; Arm-tie 1 structure is: regulate bolt 1c and be connected on two parallel-plate 1a, the 1b left end, be connected with a set bolt 1d on the two parallel-plate right-hand members, and two parallel-plate 1a, 1b are last that a plurality of adjustment hole 1e are arranged; Scalable Tiebar structure is: left bar 2b and right bar 2c are screwed in respectively on the left and right end of cylindrical shell 2a; The left end cover of left side bar 2b hangs on the set bolt 1d, and the right-hand member cover of right bar 2c hangs on the draw ring.All porose on left side bar 2b and the right bar 2c, hang on the respective bolt through the hole.Draw ring is that an annulus or structure are (structure among the figure): two otic placodes are arranged on the cuboid plate 3a, and bolt 3b is fixed on two otic placodes.A left side bar and right bar can adopt one to spin another root and cylindrical shell fixed form with cylindrical shell.Arm-tie, scalable pull bar and draw ring are metalwork.On the cylindrical shell 2a internal thread is arranged.(zinc-plated) arm-tie and (zinc-plated) draw ring are mainly used in and connect insulator string two ends connecting plate, play fixation.Scalable pull bar is mainly used in to be regulated and adaptation insulator string length and quantity.(zinc-plated) is distributed with the hole that a plurality of diameters are 17mm above the arm-tie, be used to regulate the selection of bolt installation site.
Claims (2)
1. two insulator strings are changed Work tool, it is characterized in that, are connected to form in order by arm-tie (1), scalable pull bar (2) and draw ring; Arm-tie (1) structure is: regulate bolt (1c) and be connected on two parallel-plates (1a, the 1b) left end, be connected with a set bolt (1d) on the two parallel-plate right-hand members, and on two parallel-plates (1a, 1b) a plurality of adjustment holes (1e) arranged; Scalable Tiebar structure is: left bar (2b) and right bar (2c) are screwed in respectively on the left and right end of cylindrical shell (2a); The left end cover of left side bar (2b) hangs on the set bolt (1d), and the right-hand member cover of right bar (2c) hangs on the draw ring.
2. according to claim 1 pair of insulator string changed Work tool, it is characterized in that said draw ring is that an annulus or structure are: two otic placodes are arranged on the cuboid plate (3a), and bolt (3b) is fixed on two otic placodes.
