Description
Technical field
The invention belongs to power construction equipment technical field, particularly a kind of portable LGJ- steel-cored aluminium strands positioning is held
Device.
Background technology
Need to dock LGJ- steel-core-aluminiums in 35kV-500kV high-voltage power line conductives line and the installation of electrical primary equipment
Two layers of aluminium wire line is wrapped up in the splicing fitting such as twisted wire and strain clamp, splicing sleeve, device clamp, the outside of LGJ- steel-cored aluminium strands,
Inside is zinc-coated wire cored wire.According to construction requirement, when two steel-cored aluminium strands dock, first have to two conducting wire end outer layers
Aluminium wire line peel off, then by the termination of zinc-coated wire cored wire insertion joint steel pipe crimping, primarily to undertaking tension force, finally
An aluminium pipe sleeve is mounted in conducting wire crimped outside again, which continues aluminum pipe for strain insulator.
In the prior art, it is to use-kind of portable LGJ- steel-cored aluminium strands stripping silk device to divest outer layer aluminium wire line, is led divesting
During line outer layer aluminium wire line, its drawback is：First, aluminium is caused when rotating disc type cutter rotates incision to the outer layer aluminium wire line of steel-cored aluminium strand
Silk thread broken lot, it is difficult to destroy former conducting wire process lines poling.2nd, rotating disc type cutter revolves the outer layer aluminium wire line of steel-cored aluminium strand
Turn to be subjected to displacement during incision and cause notch angle, aluminium wire line ginseng time is not neat.3rd, outer layer of the rotating disc type cutter to steel-cored aluminium strand
Aluminium wire line causes aluminium wire line end burr or crimping when rotating incision, these burrs or crimping in poling with inside pipe wall friction,
Cut and embedded inside pipe wall are produced, occurs that steel-cored aluminium strand the end of a thread is stuck in pipe when serious, advance and retreat must not.Card pipe not only increases
Workload, also results in strain clamp, splicing sleeve, the coarse crimping of device clamp aluminum steel string pipe, and overcurrent voltage drop control will be caused to lose
Normal resistance increase produces superheating phenomenon, it is also possible to causes aluminium hydraulic pressed connecting pipe to damage.These phenomenons are that crimping strain insulator continues aluminum pipe and conducting wire
Strictly forbid in joint steel pipe process.
The content of the invention
The present invention to solve the above-mentioned problems, devises a kind of portable LGJ- steel-cored aluminium strands positioning holder, is turning
When disc type cutter rotates incision to the outer layer aluminium wire line of steel-cored aluminium strand, it can ensure the cut-out of aluminum steel termination using positioning holder
Face aluminium wire line not broken lot, keep former conducting wire process lines is neat, burr crimping does not occur, operation it is accurate it is convenient, ensure construction matter
The characteristics of amount.
To achieve these goals, the technological means taken of the present invention is：
A kind of portable LGJ- steel-cored aluminium strands positioning holder, the device are included by two hinged valve semi-rings of articulated shaft
Shape positioning mould is buckled, and the free-end of positioning mould buckle is respectively arranged with connecting seat, is tightened to two connecting seats by fastener whole
Body, positioning mould buckle is internal to be installed with semi-circular positioning mould respectively, and the outside radius surface of positioning mould is equal to positioning
The inner side radius surface of mould buckle, the inner side radius surface of positioning mould are equal to the radius of steel-cored aluminium strand, the termination of the positioning mould
Protrude positioning mould buckle and be provided with a groove for being used to fix rotating disc type cutter cam.
The fastener is made of bolt and wing nut, and the connecting seat is ears, and one end of bolt is positioned at
In the ears of side, wing nut is located on the other end of bolt.
The free-end of the side positioning mould buckle is provided with handle, and handle is located at the lower end of fastener.
Be provided with positioning mould tongue in described positioning mould buckle, positioning mould be provided with match with positioning mould tongue it is recessed
The annular top of groove, positioning mould buckle and positioning mould is respectively arranged with bolt hole, and it is fixed that positioning mould is fixed on by bolt
In the mould buckle of position.
The beneficial effects of the invention are as follows：Steel-cored aluminium strand is placed in the inside of positioning mould, two valve positioning moulds and positioning mould buckle
Merge fastening, the radius of positioning mould is equal to the radius of steel-cored aluminium strand, steel-cored aluminium strand is fixed, is cutting steel wire aluminum stranded conductor
Outer layer aluminum steel when, the steel wire aluminum stranded conductor that is not cut off will not broken lot and section is neat, impulse- free robustness or crimping, can be smooth
Insertion conducting wire joint steel pipe in and strain insulator continue in aluminum pipe, avoid burr or crimping and inside pipe wall rub generation cut be difficult to it is embedding
Enter inside pipe wall phenomenon；The upper end of positioning mould is provided with a groove, and the cam of rotating disc type cutter roller is fixed in groove, can protect
The tool-post structure edge of a knife circumferentially linearity in rotary cutting is demonstrate,proved, can prevent that notch angle or the end of a thread are loose.The stripping silk device only needs one
People constructs, and can improve three times of work efficiency, ensures construction personnel's safety, reduces waste of material.
