Abstract
The invention discloses a tool for changing two strings of insulators. The tool consists of a pull plate, a telescopic pull rod and a pull ring which are connected in sequence, wherein the structure of the pull plate is that: an adjustment bolt is connected to left ends of two parallel plates; a fixing bolt is connected to the right ends of the two parallel plates; a plurality of adjustment holes are formed in the two parallel plates; the structure of the telescopic rod is that: a left rod and a right rod are screwed on the left end and the right end of a barrel body respectively; the left end of the left rod is sleeved and hung on the fixing bolt; and the right end of the right rod is sleeved and hung on the pull ring. The tool has the characteristics of simplicity, practicability and convenience for carrying, and is a tool special for changing two strings of insulators at 220 kV or below.
Description
Technical field
The present invention relates to the electric armour clamp maintenance and use 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.
Summary of the invention
The purpose of this invention is to provide a kind of two insulator strings simple and practical, that be convenient for carrying and change Work tool.
The objective of the invention is to realize like this: a kind of pair of insulator string changed Work tool, 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 invention has the beneficial effects as follows: the present invention is 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 a front view of the present invention.
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.
