Abstract

The utility model discloses anti-slip memorial alloy power circuit pipe fitting, is made of annular steel handle, steel core, the first thermal contraction one-way memory compo pipe, the second thermal contraction one-way memory compo pipe, X-shaped steel chock；X-shaped steel chock equipment, which is heat-shrinked in one-way memory compo pipe first and is heat-shrinked one-way memory compo pipe with first, forms two steel core card holes, the card hole aperture and steel core close fitting, steel core passes through the memory alloy pipes connection type itself for passing through the second steel core card hole the utility model after adopting the above scheme around annular steel handle rear end portion after the first steel core card hole and does not need the components such as screw, it avoids because fastener caused by route generates heat deforms, the ability of support tension is caused to decline, operation and security risk caused by going offline so as to caused route, so that wiring is stronger and service life is lengthened.

Description

Anti-slip memorial alloy power circuit pipe fitting

Technical field

The utility model relates to ultra-high-tension power transmission line field more particularly to a kind of golden power circuit connectors.

Background technique

Overhead transmission line road uses a large amount of crimp type electric armour clamp, they bear whole tension of route, and this Fitting is just no longer dismantled after installation.For the crimping means of transmission line hardware, currently used grounded-line compression bonding method Have: the method for forcipressure, hydraulic method and detonation pressure method, now wire clamp crimping is all according to standard compression joint technique, usually by steel core It is separated with aluminum stranded conductor, steel strand wires carry out one by one with aluminum stranded conductor.Its emphasis constructed is, steel strand wires crimped with wire clamp after by line Folder is placed on steel tower as steel core and aluminum stranded conductor load-bearing.Crimp quality of these fittings during crimping does not meet related rule It will appear the problems such as crimping armor clamp local temperature is excessively high when the requirement of journey, thus the accident that goes offline, therefore the pressure of these fittings Connecing quality has direct great influence for transmission line safety stable operation.

Utility model content

The purpose of this utility model is to provide it is a kind of can use route fever and can pre- anti-slip power circuit Pipe fitting.

To reach above-mentioned purpose, the anti-slip memorial alloy power circuit pipe fitting of the utility model, wherein by annular steel Handle, steel core, first are heat-shrinked one-way memory compo pipe, the second thermal contraction one-way memory compo pipe, X-shaped steel chock group At；Annular steel handle 1 is fixed on shaft tower by U-bolt, and X-shaped steel chock equipment is heat-shrinked one-way memory first In compo pipe and one-way memory compo pipe is heat-shrinked with first and forms two steel core card holes, which closely fits with steel core Match, steel core bypasses annular steel handle rear end portion across the second steel core card hole after passing through the first steel core card hole, and the second thermal contraction is single Journey memory alloy pipes are tightly sleeved in steel core end and overhead is in the second steel core card hole lower part.

X-shaped steel chock is heat-shrinked one-way memory compo pipe from lower part insertion first, is heat-shrinked one way note with first The contact surface for recalling alloy inside pipe wall is coarse non slip surface, and X-shaped steel chock outer end face is equipped with anti-pull-out block machine.

After adopting the above scheme, it since fastener and fixture use shape memory alloy material pipe, is not coming into operation In the case where the one the second be heat-shrinked one-way shape memory compo pipe itself to the extruding of steel core and X-shaped steel chock just It is provided with the ability of support tension, after putting into operation, the deformation of the marmem as caused by fever, internal diameter of tube body is received Contracting, increases the extruding to steel core, and first is heat-shrinked one-way shape memory compo pipe due to the inertia of X-shaped steel chock, Therefore the effect of power is all undertaken by steel core, to limit the unidirectional sliding of steel core during support tension；Second heat The deformation for shrinking one-way shape memory compo pipe makes steel core be locked, and is stuck in the first thermal contraction one-way shape memory compo pipe Outside further limits the unidirectional sliding of steel core.

Specific embodiment

For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with implementation Mode simultaneously cooperates attached drawing to be explained in detail.

Refering to Figure 1, the utility model annular steel handle 1 is fixed on shaft tower by U-bolt and (is not shown in figure Out), it is passed through among annular steel handle 1 after steel core 2 is separated with aluminum stranded conductor 6 and by bending fold, clamps X-shaped steel chock Wrapped up after 4 by the first thermal contraction one-way shape memory compo pipe 3, the end of steel core 2 is pierced by after fastener portion by fixture --- Second, which is heat-shrinked one-way shape memory compo pipe 5, wraps up.Because cable fever will make marmem deformation occurs to generate power The steel core 2 that banding surrounds, though again because environment influence leads to expanding with heat and contract with cold for pipe fitting, when restoring room temperature, memorial alloy One way shape-memory effect marmem pipe can't be made to reply original shape, to ensure that good contact Effect, while being also prevented from wiring loosening or even falling off.

In use, a steel core 2 of cable waiting is drawn, banding second is heat-shrinked one-way shape memory compo pipe 5, wears Cross first thermal contraction one-way shape memory compo pipe 3 after after annular steel handle 1 be bent 180 ° be adjacent in itself with steel core 2, then It is filled up across the first thermal contraction one-way shape memory compo pipe 3 by X-shaped steel chock 4 and is stuck in X-shaped steel chock 4 and first It is heat-shrinked in two card holes that one-way shape memory compo pipe 3 surrounds, steel handle 1 is fixed on shaft tower by U-bolt； Apply rated load or the tractive force beyond rated load before coming into operation, checks whether cable shrinks back, it is then qualified without shrinking back, have It shrinks back, needs to reinstall.

As shown in Fig. 2, X-shaped steel chock 4 is unidirectionally caught in the first thermal contraction one-way shape memory compo pipe 3 (as shown in figure 1 To be caught in from bottom to top), the first contact surface for being heat-shrinked one-way memory alloy inside pipe wall is coarse non slip surface, X-shaped steel Chock outer end face is equipped with anti-pull-out block machine 41.

Memory alloy pipes connection type of the utility model itself does not need the components such as screw, avoids because route is sent out Fastener caused by heat deformation, cause the ability of support tension decline, caused by going offline so as to caused route operation with Security risk, so that wiring is stronger and service life is lengthened.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
