Abstract

The utility model relates to a covered wire clip which belongs to a wire clipping and fastening tool and is used for distribution lines of overhead covered wires of low-voltage wires and high-voltage wires of power plants, transformer stations and other electric power systems. The utility model can also be used for dragging and fastening operations of cable installation of ships, submarine cables, laying pipelines, industry pipelines and enterprise pipelines. The utility model is provided with an upper clipping plate and a lower clipping plate which can be correspondingly opened and closed, and the upper and the lower clipping plates are circular arc shapes, long barrel type and semicircle. An inner hole of each clipping plate is a conical cavity, a rubber conical core body is installed in the cavity, the middle of the inner part of the core body is provided with a conducting wire-shaped inner hole, and the upper clipping plate and the lower clipping plate are provided with pulling rings which can tightly fix the upper clipping plate and the lower clipping plate. The utility model has the advantages of no conducting wire damage, fast wire-fastening speed and high efficiency. The utility model is an ideal wire fastening and clipping tool which is suitable for the electric power systems.

Description

A kind of insulated wire clamp device

The utility model relates to the tension disk of a kind of insulated wire clamp, stringing, is used for the utensil of operations such as the low high voltage overhead insulated wire distribution line tractive of electric power system, degree of tightness.

Along with science and technology development, the various advanced materials of electric power system constantly are used, the High-Voltage Insulation line is to put into operation in recent years in the electric industry, in the overhead insulating line process, also exist many shortcoming and defect at present, owing to there being new insulating material not have novel clamp instrument, what use at the aerial high-voltage insulated wire is that steel-fastening core aluminium hinge line fixing-line device replaces the card insulated wire, blocking big model High-Voltage Insulation ply-yarn drill does not get on, have to scalp card again to the big part of insulated wire diameter with file, so promptly trouble is undesirable again, for example YLTV low-voltage insulation line is by a lead of four twisted shapes of forming, because do not block the Line tool, just have to be with rope around tying up, be to adopt the original method operation always, not only labour intensity is big for dry method like this, man-hour is long, construction schedule is slow, inefficiency and electric industry operating personnel's personal safety do not had reliable guarantee, and coefficient of safety is low.

In view of the foregoing, the purpose of this utility model provides a kind of high efficiency, reduces labour intensity, construction schedule is fast, can guarantee reliably operating personnel's personal safety to be applicable to low High-Voltage Insulation line tension disk, has filled up the blank of clamp instrument.

The purpose of this utility model can realize by following technical proposals, a kind of insulated wire clamp device is that the train wheel bridge (3) by two microscler semicircle arcuations can separate with lower plate (4), can be a tubular to altogether the time again, it is the cavity of a taper that the outside has step Inner portion, the cone rubber core (8) that matches with it is housed in conical cavity, cone rubber core center has the intermediate throughholes that adapts with insulated wire that will clamping, one side involutory at last lower plate has outstanding respectively, the opening part of middle ear pawl (11) (12) for opening after the coincidence of ear pawl up and down is used for tightening up lower plate by fastening bolt (5), has pin-and-hole cover (7) in the fastening bolt lower end and has bearing pin (6) and be used for positioning and fixing.One side of train wheel bridge (3) has circular pipe type draw ring cover (10), and one side of lower plate (4) is one with microscler draw ring (1), and the other end of draw ring passes its external part of draw ring cover (10) of train wheel bridge and can fix by draw ring nut (9) is spacing.

The utility model compared with prior art, can make once success of clamp, do not hinder lead, stringing speed is fast, the rope that has changed original use is tied up original stupid way with the plastics band around wiring, increases work efficiency more than 2 times, reduces the work personnel, making personal safety that reliability be arranged, is the clamp utensil that desirable power construction is suitable for.

Accompanying drawing is the utility model three-dimensional structure diagram.

1--draw ring, 2--fastening nut, 3--train wheel bridge, 4--lower plate, 5--fastening bolt, 6--clamping plate bearing pin, 7--clamping plate guide, 8--rubber tapering core, 9--draw ring nut, 10--draw ring cover.

Specifically describe specific embodiment of the utility model below.

Insulated wire clamp device adopts 45 steel, plating zinc on surface, train wheel bridge (3) and lower plate (4) and middle conical cavity and cone rubber core are the main parts of this tension disk, the inner cone core is to adopt the bigger elastomeric material of coefficient of friction to make the awl core, since inside and outside when being the cone-shaped clamp, drawing presss from both sides tighter and tighter, so safe and reliable insulated wire that do not damage again, the main body of tension disk is an open-close type, outer rim has step, to gain in strength, last lower plate can adopt the 45# steel, machined into, the ear pawl can weld by processing by steel plate, the middle part of last lower plate has breach, draw ring cover 10 can be welded in the side of train wheel bridge (3), also can be cast into one and be used for fixing lower plate and fixed pull ring (1), lower plate is welded with guide (7) guide endoporus and seals in bearing pin (6) and be connected fastening bolt (5) bearing pin guide with the horizontal aperture in screw rod lower end and match, be used for clamping lower plate, (1) 1 of draw ring adopts that reinforcing bar is zinc-plated to form, one end is welded on the lower plate rear end, other end front has in the draw ring cover that screw thread seals in train wheel bridge matches with draw ring nut (9), rubber tapering sandwich (8), the outside is a tapering, and endoporus is according to wire shape, and lead is to calculate external diameter and decide, rubber tapering sandwich, Outer Taper simultaneously has breach, in order to putting lead inside, plays clamping wire.

In operation, when needing stringing, earlier rubber cone clevis core is chosen the position, the rubber sandwich opened put on the lead, then tension disk is opened in the middle of parallel the putting into, stretch away forward, put in the middle of the rubber sandwich, the tight good hold-doun nut stringing of the tension disk that closes then, wire grip are hung tension disk draw ring Inner, get final product stringing.

Claims

1, a kind of insulated wire clamp device, but it is characterized in that by two microscler semicircle arcuations and centre being the train wheel bridge (3) and lower plate (4) of conical cavity folding, one side after last lower plate is involutory has the pawl of ear up and down (11) that outstanding centre is an opening respectively, (12), the lower plate (4) of lower end that can be by fastening bolt (2) fastening bolt at the opening part of ear pawl up and down has pin-and-hole cover (7) and bearing pin (6), one side of train wheel bridge (3) has circular pipe type draw ring cover (10), lower plate (4) is an one with the annular draw ring of length (1) of one end, the other end string of draw ring is crossed the draw ring cover (10) of train wheel bridge and can be fixed by draw ring nut (9) is spacing, the cone rubber core (8) that matches with it is housed in conical cavity between last lower plate (3) (4), and cone rubber core center has the intermediate throughholes that adapts with insulated wire.Having slotted eye on the housing of last lower plate can adopt pin block to fix rubber core.
