Abstract
The utility model discloses a shape memory alloy connection piece (a screwed tube or a screwed bar) in the technical field of connection elements. The shape memory alloy connection piece can be used for connecting pipelines and cables. The shape memory alloy connection piece can be a screwed tube or a screwed bar; one end (or two ends) of the screwed tube or the screwed bar serving as the shape memory alloy connection piece has (or have) a screwed structure (or screwed structures). When in use, the screwed tube or the screwed bar serving as the shape memory alloy connection piece works needs to be heated by an external source. Before use, the screwed tube or the screwed bar serving as the shape memory alloy connection piece is subjected to precompression and thermal treatment. The screwed tube or the screwed bar serving as the shape memory alloy connection piece can be used for replacing the conventional manual or mechanical bolt connection, so that a function of connecting pipelines and cables is realized. The shape memory alloy connection piece is suitable for occasions with small spaces, such as an aerospace, high altitude and seabed where manual assembly is not easy to implement; particularly, the shape memory alloy connection piece is suitable for connection occasions needing relatively large compression force. The screwed tube or the screwed bar serving as the shape memory alloy connection piece supplies large compression force and is high in locking force and difficult to fall down.
Description
Technical field
The utility model relates to and is used for a kind of marmem link (threaded pipe or threaded bar) that pipeline is connected with cable, belongs to connecting element.
Background technique
At present, the pipeline in field and being connected of cable such as Aero-Space, offshore platform, ocean fiber optic cable communications, railway communication and railway electrical network, overhead electrical network, fire-fighting adopt armstrong's patent to connect usually, and connecting element is mainly bolt.Be characterized in that the bolt Material Strength is high, can dismantle repeatedly.But,,, adopt artificial assembling to be difficult for realizing or slowly like occasions such as aerospace, high-altitude, seabed, space are narrow and small for some special occasions.Especially connection needs the occasion of big pretightening force, is difficult to realize through manual work.Behind artificial pretension, also be prone to the loosening situation such as pipeline leakage or connection get loose that cause.
The model utility content
The utility model is to some special occasions in the existing technology, and the artificial assembling of employing is difficult for realizing or is slow.Connection needs the occasion of big pretightening force; Be difficult to realize through manual work; Behind artificial pretension, also be prone to and loosening cause pipeline to reveal or connect defective such as to get loose and a kind of marmem link is provided, the restoring force that provides when utilizing the reminiscence of marmem realizes being connected of pipeline and cable; The compressive force that connects and fix is big, and assembling is quick.
The marmem link that the utility model provides is threaded pipe or threaded bar, and an end (or two ends) of described marmem link threaded pipe or threaded bar has worm structure.
In general, marmem threaded pipe wall thickness is at 0.5mm～1000mm.Marmem threaded bar diameter is at 1mm～1000mm.The intermediate section length of marmem threaded pipe or threaded bar is at 1mm～5000mm.
Marmem link threaded pipe or threaded bar material that the utility model provides can adopt existing shape memory alloy material, like binary or ternary Ti-Ni alloy, copper base alloy or iron-base marmem etc.
Need the external source heating when marmem threaded pipe or threaded bar work.Marmem threaded pipe or threaded bar are passed through precompression and heat treatment before use.
Marmem considerable reverse transformation of a kind of strain capacity and bigger restoring force can occur after heating surpasses critical phase transition temperature.In this process, can export 400-650MPa stress, in addition higher.The restoring force that utilizes marmem reverse transformation process to produce can be realized the linkage function of pipeline and cable.The linkage structure of pipeline and cable by marmem threaded pipe or threaded bar, threaded pipe or cable, packing ring, be connected bearing and constitute.Earlier pipeline is docked in being connected bearing with cable during use; And recess and marmem threaded pipe or threaded bar on the joint are aligned; Through external source heating marmem link threaded pipe or threaded bar to more than the phase transition temperature; The link elongation produces powerful compressive force, thereby realizes the linkage function of pipeline and cable.Utilize this marmem link threaded pipe or threaded bar can be used for substituting the manual or mechanical bolt of conventional artificial and connect, realize the linkage function of pipeline and cable.
The linkage structure of this pipeline and cable by marmem threaded pipe or threaded bar, threaded pipe or cable, packing ring, be connected bearing and constitute.The using process of this marmem threaded pipe or threaded bar; Earlier pipeline is docked in being connected bearing with cable during use; And recess and marmem threaded pipe or threaded bar on the joint are aligned; To more than the phase transition temperature, the link elongation produces powerful compressive force, thereby realizes the linkage function of pipeline and cable through external source heating marmem link threaded pipe or threaded bar.
The utility model has the advantages that: utilize this marmem link threaded pipe or threaded bar can be used for substituting the manual or mechanical bolt of conventional artificial and connect, realize the linkage function of pipeline and cable.Be applicable to like occasions such as spaces such as aerospace, high-altitude, seabed are narrow and small, be difficult for artificial assembling occasion.Especially connection needs the occasion of big compressive force.The compressive force that this marmem link threaded pipe or threaded bar provide is big, and coupling mechanism force is strong, is difficult for getting loose.

Embodiment
Below in conjunction with ssembly drawing and embodiment the structure with marmem link threaded pipe or threaded bar connecting pipeline and cable that the utility model relates to is explained.
Pipeline as shown in Figure 1 and cable linkage structure, by marmem threaded pipe or threaded bar 1, connect bearing 2, threaded pipe or cable 3, packing ring 4 constitutes.One end (or two ends) of threaded pipe or threaded bar has worm structure, marmem threaded pipe or threaded bar 1 total length 40mm, and active section length is 30mm, active section outside diameter 11mm, diameter of bore are 7mm.Screw thread is M16mm, and thread depth is 10mm.It is 0.5mm that pipeline or cable are furnished with the recess height, and width is 11.3mm.Pipeline or cable 3 outside diameters are 40mm, and diameter of bore is 30mm.Packing ring 4 thickness are about 1mm.When using marmem link threaded pipe or threaded bar 1; Earlier pipeline is inserted with cable 3 and be connected bearing 2; Pipeline and cable 3 recesses and marmem link threaded pipe or threaded bar 1 are aligned; Put into marmem link threaded pipe or threaded bar 1 then; To more than the phase transition temperature, marmem link threaded pipe or threaded bar 1 elongation produce powerful compressive force, realize that pipeline is connected with cable 3 through external source heating marmem link threaded pipe or threaded bar 1.
Marmem link threaded pipe or threaded bar that pipeline that the utility model relates to or cable connect, the compressive force and the coupling mechanism force that provide are big, and assembling is quick, is applicable to the difficult occasion of the inconvenient or artificial locking of artificial assembling.Can be widely used in the pipeline in fields such as Aero-Space, offshore platform, ocean fiber optic cable communications, railway communication and railway electrical network, overhead electrical network, fire-fighting and the occasion that is connected of cable, the extensive application prospect.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
