Abstract
The invention relates to a core rod replacing device for a wall bushing, which includes an outer sleeving piece formed through sequentially connecting a duckbilled pad (5), a bushing (6) and a top cap (4), wherein a core rod (3) is accommodated inside the outer sleeving piece; the front end of the core rod (3) extends out of the duckbilled pad (5) and is propped against the inside of a rubber seal ring (1); a clamping frame (8) used for fixing the core rod (3) is arranged inside the bushing (6); the clamping frame (8) is connected with a threaded rod (12) penetrating out of the top cap (4); and a screw (11) positioned on the outer side of the top cap (4) is arranged on the threaded rod (12). The core rod replacing device for the wall bushing has the following advantages: firstly, through the adoption of the principle of the reactive force, the threaded rod penetrates through the top cap, the screw is fastened and screwed to press the top cap, the bushing and the duckbilled pad, so as to press the seal ring, as a result, a pin hole is extruded and exposed; and secondly, a V-type opening is formed lengthways at the middle of the front end of the duckbilled pad, a fixing pin can be inserted simply and quickly by one person, and the problem that the pin cannot be inserted in the pin hole in place due to the external elastic deformation of the seal ring can be solved.
Description
Technical field
The present invention relates to a kind of instrument used when changing wall bushing plug.
Background technology
Wall bushing is used for electric substation's High-Voltage Electrical Appliances, for wire through earth conductor dividing plate, wall or electrical appliance enclosure, supports that current-carrying part makes it over the ground or casing insulation.Variety classes is divided into, at present on-the-spot many employing aluminium conductor porcelain bushing shells according to through the conductor at its center and the difference of outer insulating material.Because wall bushing conductor part easily produces couple corrosion, contact surface temperature rise is too high and cause conductor tab to burn out, and often makes the conductor life-span greatly be shorter than the insulator life-span.When running into this type of defect, if take the method directly changing conductor plug during process in the past, due to existing commercially not relevant construction tool, cause the difficulty when fixing oil resistant rubber seal with fixture very big; Therefore all can directly change whole sleeve pipe, this method not only needs again to purchase new sleeve pipe and parts, and makes operation power off time long, Technical Economy extreme difference.
Summary of the invention
The object of the invention is to design a kind of wall bushing plug changer, by the method for operating personnel's tightening nut, just detachable or installation conductor plug, saves operating cost, improves construction quality and operating efficiency, facilitate operative.
The technical solution used in the present invention is for this reason: the present invention includes the package assembly be connected in sequence by duckbilled pad (5), sleeve pipe (6) and top cap (4), plug (3) is contained in package assembly, plug (3) front end is stretched out and is supported in rubber sealing ring (1) from duckbilled pad (5), the clamping frame (8) of stationary core rod (3) is established in sleeve pipe (6), clamping frame (8) connects a threaded bar (12) passed from top cap (4), threaded bar (12) is established the screw (11) being in outside, top cap (4).
Described duckbilled pad (5) front end is horizontal flat duckbill, and V-type mouth is longitudinally opened in middle part, and rear end is hollow circuit cylinder.
The cross section of described clamping frame (8) is U-shaped, and horizontal cross opens hole to insert pin (7).
Described sleeve pipe (6) can be split type, is spliced by each section of copper sheathing.
Packing ring (10) is established between described screw (11) and top cap (4).
Advantage of the present invention is: 1, utilize reaction force principle, by threaded bar through top cap, tightens holding screw, makes it oppress top cap, sleeve pipe and duckbilled pad, and then compressing sealing ring, reaches and pinhole is extruded the object exposed; 2, after the front center of duckbilled pad has longitudinally opened V-type mouth, singlely can insert fixator pins quickly and easily, avoid due to the outside elastic deformation of sealing ring and pin cannot be inserted into the problems such as position in pinhole.

Detailed description of the invention
As shown in the figure: during use, first arrange on conductor plug 3 at copper (aluminium) and be inserted in duckbilled pad 5, V-type mouth side is near pinhole 2.Copper (aluminium) on clamping frame 8U type muzzle is arranged conductor plug 3, clamping frame 8 through hole and copper (aluminium) are arranged conductor plug 3 and are tightened up a screw after hole aligns, the two phase chain is incited somebody to action with pin 7 and little pin 9, sleeve pipe 6, top cap 4 is inserted in again successively from threaded bar 12 side, and on three being spun, in threaded bar 12, be finally inserted in packing ring 10, holding screw 11 of screwing on successively.This structure of simplifying is portable and simple to operate, singlely can complete whole operation, can avoid needing to transfer a great deal of workman's common operational.
During use, tighten holding screw 11 with corresponding spanner, duckbilled pad 5 by conductance extruding rubber sealing ring 1, to pinhole 2 exposes suitable size, pin can be inserted into position.After pin is inserted into position, unscrew holding screw 11, lay down holding screw 11, packing ring 10, top cap 4, sleeve pipe 6 successively, extract pin 7, unload clamping frame 8, duckbilled pad 5.So far, change the operation of wall bushing plug to complete.This mode is efficiently saved, simple to operation and ensure safety.
The front end of duckbilled pad 5 of the present invention is horizontal flat duckbill, and middle part is longitudinally opened V-type mouth and facilitated pin to insert, and rear end is hollow circuit cylinder, is with the fine and closely woven screw thread of five circles outward.
Pin 7 of the present invention is tack type, and top is tubbiness cylinder, bottom is omit slender cylinder, and plug 5 is firm to be connected to utilize this pin 7 clamping frame 10 and copper (aluminium) can be arranged.
