Description

Cable fixture

Technical field

The utility model relates to the cable fixture of clamping electrified cable.

Background technique

In the super heavy oil development oil recovery process in oil field, the heating in medium frequency cable is the critical facility in production process, Chinese patent 95233278 discloses a kind of oil well " heating hollow sucker rod private cable ", and this cable is by the intermediate frequency control cabinet, in hollow rod is lowered into oil well.This cable exposure is in the part of well head, adopt sebific duct or cable insulation leather material looping, zero line contact and live wire immovable point are arranged in the position of wellhead polish rod head end, if not fixation, can swing because of pumping unit up-downgoing to-and-fro motion, mechanical wear cable outer surface insulated hull easily occurs, and sparking, electric leakage accident occur.

In daily management, usually coarse processing method is to be bundle with iron wire, the rope made of hemp or adhesive tape, cable zero line and live wire are tied up and be fixed up, like this due to the part of cable exposure at well head, the disunity of binding and lack of standardization, binding easily occurs come off, cause cable surface insulated hull mechanical wear or fracture, the accidents such as sparking, electric leakage closely occur.Fixation method rate of fault and the cable maintenance cost of this binding are high, and the frequent fault that occurs also increases difficulty to daily management, therefore,, for the needs of producing upper and cost control, are badly in need of the cable fixture of a kind of special use of development.

Summary of the invention

The utility model is In view of the foregoing completed just, its purpose is to provide a kind of cable fixture, it firmly fixes the zero line of cable and live wire to be in the same place with outstanding rope, like this, when zero line and live wire are namely done while pumping with pumping unit with outstanding rope, can not swing, thereby can not wear and tear cable sheath, cause the accidents such as sparking, electric leakage.

Cable fixture of the present utility model has the clamping plate of two make-ups, be formed with the open-minded hole of space to pressing from both sides inboard at clamping plate, want in the outstanding rope of clamping and open-minded hole that electrified cable is arranged in, be provided with the bolt that the outstanding rope in the hole of slitting and electrified cable are clamped in the both sides, hole of slitting.

The hole of slitting is the open-minded hole that forms pressing from both sides two slot make-ups that inboard forms respectively at two clamping plate, and one of them open-minded hole is the open-minded hole of the outstanding rope of the outstanding rope of sandwiched, between two bolts of the clamping plate of make-up; The zero line that another two adjacent open-minded holes are the sandwiched electrified cable and the electrified cable of the live wire hole of slitting, between another two bolts of the clamping plate of make-up.

So that the mode of clamping plate integrally bending forms the slot that forms the open-minded hole of outstanding rope; Form and form the slit slot in hole of electrified cable in the mode of the inner side surface of the make-up at clamping plate depression.

The slot that forms the hole of slitting is semicircle, thereby the hole shape that slits becomes circle.

The aperture in the open-minded hole of outstanding rope is slightly less than the diameter of the outstanding rope of wanting clamping, and the aperture in two open-minded holes of electrified cable equates, and is slightly less than the zero line of the electrified cable of wanting clamping and the diameter of live wire.

Utilize said structure, can be more securely the zero line of electrified cable and live wire and outstanding rope be fixed together, like this, when zero line and live wire are done while pumping with pumping unit, prevent to come off and swing, thereby can not wear and tear cable sheath, cause the accidents such as sparking, electric leakage.

Embodiment

As depicted in figs. 1 and 2, cable fixture of the present utility model has 1, two clamping plate of clamping plate of two make-ups by bolt 4 connections.Be formed with outstanding rope hole 2 and two adjacent electrified cables holes 3 of slitting of slitting at clamping plate 1 to pressing from both sides inboard.Hang rope 5 and be folded in the open-minded hole 2 of outstanding rope, the zero line 6 of electrified cable and live wire 7 are folded in respectively in the open-minded hole 3 of two electrified cables.

Outstanding rope slits hole 2 between two bolts 4 of the clamping plate 1 of make-up, and two electrified cables slit hole 3 between another two bolts 4 of the clamping plate 1 of make-up.

Outstanding rope hole 2 and the electrified cable hole 3 of slitting of slitting is the open-minded hole that forms at two slot make-ups that the folder inner side surface is formed respectively of two clamping plate 1.

So that the mode of clamping plate 1 integrally bending forms the slot that forms the open-minded hole 2 of outstanding rope; Form and form the slit slot in hole 3 of electrified cable in the mode of the inner side surface of the make-up at clamping plate 1 depression.

Preferably, the slot that forms the open-minded hole 2 of outstanding rope and the open-minded hole 3 of electrified cable is semicircle, thereby makes the open-minded hole 2 of outstanding rope and the open-minded hole 3 of electrified cable all form circle.

And preferably, the aperture in the open-minded hole 2 of outstanding rope is slightly less than the diameter of the outstanding rope 5 of wanting clamping, and the aperture in two open-minded holes 3 of electrified cable equates, and is slightly less than the zero line 6 of the electrified cable of wanting clamping and the diameter of live wire 7.

Below using method and the effect of this cable fixture are described.

When pumping unit is quit work, two clamping plate 1 are configured in the both sides of outstanding rope 5 and electrified cable, be located in respectively the open-minded hole 3 of two electrified cables so that hang 5 zero line 6 and the live wires 7 that are located in the open-minded hole 2 of outstanding rope and electrified cable of restricting, then utilize bolt 4 that two clamping plate 1 are linked together and tighten, thereby will hang zero line 6 and live wire 7 clampings of rope 5 and electrified cable.

Like this, because the zero line 6 and the live wire 7 that utilize above-mentioned cable fixture will hang rope 5 and electrified cable are fixed together, so when the zero line 6 of electrified cable and live wire 7 during with the pumping unit to-and-fro motion, prevented coming off and swinging of electrified cable, thereby the crust of the electrified cable that can not wear and tear, cause the accidents such as sparking, electric leakage.

In addition, also can form aperture and be equal to or greater than respectively the outstanding rope 5 of wanting clamping and zero line 6 and the live wire 7 of electrified cable hanging rope hole 2 and the electrified cable hole 3 of slitting of slitting.At this moment, can be at the suitable liner of installation between hole and cable that slits, to keep cable fixture to outstanding rope 5 and the zero line 6 of electrified cable and being fixedly clamped of live wire 7.

In addition, the shape in the open-minded hole 2 of outstanding rope and the open-minded hole 3 of electrified cable is not limited to circle, also can form such as other shapes such as ellipses.

In addition, the mode that is connected and fixed of two clamping plates 1 is not limited to above-mentioned mode of execution, also can use two or three above bolts 4 to be connected and fixed, perhaps use other known fastening means, as long as two clamping plates 1 is fixedly clamped, hang zero line 6 and the live wire 7 of rope 5 and electrified cable.
