Abstract
The invention relates to a disassembling tool of a pulling and inserting plug in an RMU (Ring Main Unit). The disassembling tool is characterized by comprising a U-shaped plate (3), wherein the bottom part of the U-shaped plate (3) is provided with a threaded hole, a screw rod (2) is inserted in the threaded hole, one end, which is far away from the U-shaped plate (3), on the screw rod (2) is provided with a handle (1) which is vertical to the screw rod (2), one end, which stretches into the U-shaped plate (3), on the screw rod (2) is provided with a connecting seat, and the connecting seat is connected with a circular clamping head (4). Test shows that after the adoption of the disassembling tool disclosed by the invention, the time for replacing the pulling and inserting plug in the RMU can be effectively shortened, thus the time for replacing the RMU can be greatly quickened, maintaining, overhauling and construction operation can be convenient, and the labor productivity is facilitated to be increased.
Description
Technical field
The present invention relates to a kind of ring main unit unplugg extracting tool.
Background technology
In recent years, development along with city, The Surroundings in Cities is beautified to requirement more and more higher, often require power supply enterprise to change overhead transmission line into cable laying, for urban beautification establish a firm foundation, in I and II city, change all overhead transmission lines into cable laying line cord for this reason, cause accordingly ring main unit prevailing.In repair and maintenance work, when ring main unit unplugg breaks down, need to dismantle unplugg, but current be mainly by manually laying down unplugg, the strength needing is very large, causes time-consuming taking a lot of work, and has extended power-off time.
Summary of the invention
The object of this invention is to provide a kind of ring main unit unplugg extracting tool simple in structure, easy to use, the unplugg in can quick-detachment ring main unit after use.
A kind of ring main unit unplugg extracting tool, its special feature is: comprise U-shaped plate, in this U-shaped plate bottom, have screwed hole, in this screwed hole, be fitted with screw rod, one end away from U-shaped plate on this screw rod is provided with the handle vertical with this screw rod, and one end of stretching on this screw rod in U-shaped plate is provided with Connection Block, this Connection Block is connected with the dop of a ring-type.
Wherein on dop, be provided with draw-in groove, on this draw-in groove inwall, be coated with rubber blanket or plastic mattress.
Wherein said Connection Block is connected with dop by screw thread, or this Connection Block is connected with dop by securing member.
Through probationary certificate, adopt after extracting tool of the present invention, can effectively shorten the time of changing unplugg in ring main unit, thereby greatly accelerate to change the time of ring main unit, thereby be convenient to maintenance, maintenance, construction operation, be conducive to raise labour productivity.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is a kind of ring main unit unplugg extracting tool, comprise U-shaped plate 3, in these U-shaped plate 3 bottoms, have screwed hole, in this screwed hole, be fitted with screw rod 2, one end away from U-shaped plate 3 on this screw rod 2 is provided with the handle vertical with this screw rod 21, and one end of stretching on this screw rod 2 in U-shaped plate 3 is provided with Connection Block, and this Connection Block is connected with the dop 4 of a ring-type.
Wherein on dop 4, be provided with draw-in groove, for example, in 6 jiaos or other and the corresponding draw-in groove of unplugg shape, on this draw-in groove inwall, be coated with rubber blanket or plastic mattress, thereby can avoid damaging unplugg, this rubber blanket or plastic mattress are bolted on draw-in groove inwall or by glue on draw-in groove inwall.
Wherein Connection Block is connected with dop 4 by screw thread, or this Connection Block is connected with dop 4 by securing member, thereby can change so different dop 4, can adapt to dissimilar unplugg.
Centring ring that in addition can also mounting circular ring shape at U-shaped plate 3 top open parts, this centring ring is welded on U-shaped plate 3 top open parts, can strengthen the intensity of U-shaped plate 3, thereby can also make screw rod keep vertical more convenient dismounting by centring ring and contacting of ring main unit internal partition.
Using method of the present invention is: as shown in Figure 1, the dop 4 of U-shaped plate 3 top open parts is stretched in ring main unit and connected with unplugg, then fix U-shaped plate 3, rotary handle 1, can take off unplugg by screw rod 2, Connection Block, dop 4 synchronous rotaries successively.When needs are installed unplugg, except the rotation direction of handle 1 on the contrary, other step is turned around substantially.
Claims (3)
1. a ring main unit unplugg extracting tool, it is characterized in that: comprise U-shaped plate (3), in this U-shaped plate (3) bottom, have screwed hole, in this screwed hole, be fitted with screw rod (2), in the upper one end away from U-shaped plate (3) of this screw rod (2), the handle (1) vertical with this screw rod (2) is installed, and one end of stretching on this screw rod (2) in U-shaped plate (3) is provided with Connection Block, this Connection Block is connected with the dop (4) of a ring-type.
2. ring main unit unplugg extracting tool as claimed in claim 1, is characterized in that: wherein on dop (4), be provided with draw-in groove, on this draw-in groove inwall, be coated with rubber blanket or plastic mattress.
3. ring main unit unplugg extracting tool as claimed in claim 1 or 2, it is characterized in that: wherein said Connection Block is connected with dop (4) by screw thread, or this Connection Block is connected with dop (4) by securing member.
