Conducting wire gripping channel is circumferentially sequentially distributed, and positioning mast axis is overlapped with to receivable column axle of spring.
The various conducting wires situation different there is thickness, especially relatively thinner conducting wire, it is possible to will appear fixation
Not tight situation, so as to cause to shake, slide, there are security risks.In the present invention, conducting wire is fixed on the first anchor ear
(the first screw wears two the first connecting plates, and the first screw and two equal spiral shells of the first connecting plate at this time after in conducting wire gripping channel
Line connection, but the first stud of the first screw does not enter locking air cavity also), the first screw of turn can be continued, connect the first stud
Secondary locking piston is touched and presses, a part of hydraulic oil locked in oil pocket is forced out, and it is locked oil pipe and enters ring internal oil channel, from
And press that positioning column is mobile towards conducting wire clamping passage axis, and finally make positioning column presses the tight conducting wire of side pressure.Such one
Come, even if conducting wire is relatively thin or epidermis is softer, can also ensure fixed.In addition, under cold weather conditions, it may outside conducting wire
Ice sheet is had, if only the first anchor ear directly embraces conducting wire, is easy to appear after skidding ice-out the problem of skidding.In the present invention,
Positioning column compresses in wire process, ice sheet is directly squeezed to broken, and firm compression conducting wire by the way, fixed effect is more preferably.It should be noted that
, when secondary locking piston contact limit body, top plug spring is in compressive state, it may be assumed that top plug spring is in compression shape always
State, so remaining the trend for pushing secondary locking piston, but the position of secondary locking piston depends entirely on the first screw
It is unrelated with the hydraulic oil volume change of ring internal oil channel etc. to the actuating length of secondary locking piston, once the first screw leaves
Secondary locking piston, secondary locking piston remain in the position of contact limit body.Between the ring internal oil channel of two the first semi-rings
It is connected to by metal bellows, so the opposite open or close of the first semi-ring will not influence the normal work of oil circuit.
One of first connecting plate is equipped with anti-guarantor's cylinder body 6, instead protects in cylinder body to be equipped with to be slidingly sealed with anti-guarantor's cylinder body and match
Anti- guarantor's first piston 61 for closing, with it is anti-protect cylinder body be slidingly sealed anti-guarantor's second piston 62 of cooperation and with anti-guarantor's cylinder body inner sidewall it is close
The fixed anti-guarantor's partition 63 of sealing, it is anti-to protect first piston and anti-protect between second piston is connected by anti-keep-alive stopper rod 64, anti-guarantor every
Anti- guarantor's cylinder interior is separated into anti-guarantor main chamber 6a and protects auxiliary chamber 6b with counter by plate, and anti-keep-alive stopper rod passes through and instead protects partition, and anti-keep-alive
Stopper rod is slidably connected with anti-partition of protecting, it is anti-protect first piston be in it is anti-protect in main chamber, it is anti-protect second piston be in it is counter protect it is auxiliary intracavitary,
For anti-first piston of protecting by the anti-main air cavity 6d for protecting and being separated into main oil pocket 6c inside main chamber and be communicated with the atmosphere, anti-second piston of protecting will
The anti-auxiliary air cavity 6f for protecting auxiliary intracavitary part and being divided into auxiliary oil pocket 6e and being communicated with the atmosphere, main air cavity, main oil pocket, auxiliary air cavity and auxiliary oil pocket
It is sequentially distributed along first piston glide direction is instead protected, anti-guarantor's spring 65 is equipped in main air cavity, it is anti-to protect the anti-guarantor's cylinder of spring one end connection
Body, anti-to protect the anti-guarantor's first piston of spring other end connection, anti-spring of protecting is in compressive state always, and anti-axle of spring of protecting is parallel to
Anti- to protect first piston glide direction, anti-guarantor's first piston glide direction, which is parallel to, instead protects second piston glide direction, and auxiliary oil pocket is logical
It crosses anti-oil pipe of protecting to be connected to the ring internal oil channel on one of them first semi-ring, anti-protect is full of hydraulic oil in oil pipe and auxiliary oil pocket, main
Always hydraulic oil is full of in oil pocket.
After two conducting wires are compressed respectively by the positioning column on two the first anchor ears, workpeople can be carried out pole operation etc.
It operates.Since pole operation process needs the regular hour, it is again sometimes that multiple high-tension poles are erect together, is not necessarily
Next high-tension pole is erect again after having erect a high-tension pole, therefore sometimes conducting wire struts the time and needs to maintain more than ten
Hour.But field work, many place day and night temperatures are very big, and ratio can be generated to the hydraulic oil in ring internal oil channel by expanding with heat and contract with cold
Large effect (liquid is affected bigger than solid), i.e., when hydraulic oil volume has more apparent variation, especially shrinkage,
Positioning column can be not fixed firmly obviously to contract so as to cause conducting wire.When heat expansion, positioning column is displaced outwardly presses more by conducting wire
Tightly, since the compression degree originally to conducting wire is proper, additionally apply more pressing force again, be easy to conducting wire
Crust causes to damage.And in the present invention, it is described on the basis of visual angle in Fig. 2: there are the structures such as anti-guarantor's cylinder body, once
External temperature subtracts greatly, then hydraulic oil also shrinkage in main oil pocket, it is anti-protect spring and anti-will protect under first piston push away, anti-protect the to drive
Two pistons move down, and a part of hydraulic oil is flowed into ring internal oil channel and compensated in auxiliary oil pocket, to prevent benefit positioning column from retracting
It is more, continue to ensure the clamping effect to conducting wire.On the other hand, once the big layer of external temperature, then hydraulic oil also heat expansion in main oil pocket,
Anti- first piston of protecting moves up, so that anti-second piston of protecting be driven to move up, auxiliary oil chamber volume becomes larger, a part of liquid in ring internal oil channel
Pressure oil flows into auxiliary oil pocket and compensates, so that the increased additional volumes of hydraulic oil heat expansion institute in ring internal oil channel are cut down,
The damage of wire sheath caused by tension is pressed to obtain to can avoid positioning column.It should be noted that instead protect spring is in pressure always
Contracting state, so remaining the anti-trend for protecting first piston that pushes down on, but the anti-position for protecting first piston depends entirely on
The actual volume of hydraulic oil in main oil pocket, it is unrelated with the hydraulic oil volume change of ring internal oil channel etc..
