Memorial alloy be it is a kind of its deformation occurred at a lower temperature can be completely eliminated after heat temperature raising, recover it
The alloy material of original-shape before deformation.Marmem deforms at a lower temperature, after heating before recoverable deformation
Shape, this shape-memory phenomena present in heating process are referred to as one-way memory effect.The memory that the present embodiment uses
Alloy is one-way memory alloy.
Referring to Fig. 1, memory alloy pipes 100 include the first compo pipe 10 and the second compo pipe 20, each compo pipe are in
Hollow circular cylinder, and opening is provided with along its length, central angle corresponding to a smooth open contour is α, and α size is typically set in 5 °
~25 °, steel core diameter is bigger, it is necessary to which the opening central angle alpha set is bigger.The opening side and second of first memory alloy pipes 10
The opening side of memory alloy pipes 20 is fixedly connected, and whole compo pipe is in ω shapes.
At present at a distance in aerial electric line, steel-cored aluminium strand is widely used, steel core 300 mainly plays increase intensity
Effect, aluminum stranded conductor 400 mainly play a part of to transmit electric energy.Some steel-cored aluminium strand outer layers are additionally provided with insulating barrier 500, and safety is resistance to
With, it is anti-oxidant, anticorrosive, play a protective role.Different according to voltage, wire sectional area is also different.
For the thickness of memory alloy pipes 100 typically between 2~10mm, the wire tension that steel core is subjected to is bigger, and memory is closed
The thickness of golden pipe 100 is thicker；Steel core diameter is bigger, and the thickness of memory alloy pipes 100 is thicker.The length of memory alloy pipes 100 with
The proportional setting of wire tension and steel core diameter that steel core is subjected to, typically in 10~100CM.
Referring to Fig. 2, each alloy bore size is R, the radius for the steel core 300 that memory alloy pipes 100 need to clamp is
R, R ＞ r, ensure in the fully-inserted each compo pipe of the energy of steel core 300, convenient installation.
Referring to Fig. 3, ω shapes are made in one-way shape memory compo pipe at low temperature, steel core is inserted in memory alloy pipes 100,
After assembling, the external heat of memory alloy pipes 100 is given, memorial alloy is fast to thermotonus, and memory alloy pipes 100 will soon be to it
Original-shape recovers, in closure state.Due to the presence of steel core, memory alloy pipes can not be retracted to interior when it stops naturally
Footpath, so as to which memorial alloy tube wall has strong pressure to steel core 300, play the purpose of firm connection.
Referring to Fig. 4, the external stability of memory alloy pipes 100 is welded with steel handle 200, will by steel handle 200
Steel tower or shaft tower in the fixed steel core and transmission line of electricity held tightly are fixedly mounted, and play the load-bearing to steel-cored aluminium strand and winding displacement.
The method of wire clamp crimping now is all according to standard compression joint technique, is usually separated steel-cored aluminium strand, steel strand wires
Carried out one by one with aluminum stranded conductor, wire clamp is placed on steel tower to be held for steel-cored aluminium strand by steel strand wires after being crimped with pipe joint
Weight.
Embodiment one：
Referring to Fig. 5, the steel core 300 in a steel-cored aluminium strand of the crimping of needs is inserted in memory alloy pipes 100
The first memory alloy pipes 10 in, by the steel core 300 in another steel-cored aluminium strand insert in memory alloy pipes 100 second note
Recall in compo pipe 20.Assemble, give the external heat of memory alloy pipes 100, make its heated recovery original-shape, start slowly to close
Close, ∞ shapes are faded to by ω shapes.Due to the insertion of steel core, it is hindered to resile completely, therefore memory alloy pipes 100
Inwall has powerful pressure to the steel core 300 for being inserted the heart, so as to reach the effect of holding.
Two steel-cored aluminium strands for needing to crimp respectively remember by the first memory alloy pipes 10 and second through memory alloy pipes 100
The holding of compo pipe 20 is recalled, it is achieved thereby that the connection of two aluminium steel conductors.
The outside weldings of memory alloy pipes 100 have steel handle 300, by steel handle 300 will the fixed steel core held tightly with
Steel tower or shaft tower in transmission line of electricity are fixedly mounted, and play the load-bearing to steel-cored aluminium strand and winding displacement.
Embodiment two：
Referring to Fig. 6, the steel core 300 for the two section steel-cored aluminium strands for needing to connect is separated, first segment steel core 301 is worn
The first memory metal pipe 10 is crossed, the second section steel core 302 passes through the second memory metal pipe 20 in the same direction；Two section steel cores pass through memory metal
After pipe 100, after bending 180 ° in the air, first segment steel core 301 inserts the second memory metal pipe 20, and the second section steel core 302 inserts
First memory metal pipe 10.First steel core 301 and the lap of the second steel core 302, it is mutually nested.
Assemble, give the external heat of memory alloy pipes 100, make its heated recovery original-shape, start slowly to close, by ω
Shape fades to ∞ shapes.Due to the insertion of steel core, it is hindered to resile completely, therefore the inwall pair of memory alloy pipes 100
The steel core 300 for being inserted the heart has powerful pressure, so as to reach the effect of holding.
The first segment steel core 301 and second of the present embodiment saves the connection of steel core 302, is taken up in order of priority by two memorial alloys
The holding of pipe is fixed, then is inverted by 180 ° of distortion, is increased frictional force, is improved the bearing capacity of steel core；Two section steel cores are mutually embedding
Set, further increase frictional force, improve the steadiness of two section steel core connections.
The outside weldings of memory alloy pipes 100 have steel handle 300, by steel handle 300 will the fixed steel core held tightly with
Steel tower or shaft tower in transmission line of electricity are fixedly mounted, and play the load-bearing to steel-cored aluminium strand and winding displacement.
Whole installation process, without the use of Large Hydraulic Equipment, it is especially apparent in the local advantage of apparatus inconvenience transport.Note
It is more sensitive to temperature to recall alloy, can quickly realize obvolvent, greatly reduces the time of construction.Reduce big machinery carrying and
Use, shorten the engineering time, using efficiency is improved, greatly reduce each side's cost.And one-way memory alloy is used, its deformation is
Expendable, after temperature decline, rudder type pipe joint of memory alloy throws away presentation closed form, without worrying pipe joint by temperature shadow
Sound is repeatedly elastic, and security performance is greatly enhanced.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model should be included in
Within the scope of protection.
