When making, can more it is intuitive accurately judge cable elbow-shaped head apart from the distance between ring main unit high-tension cable casing,
Further, the second activity semilune folder 16 and described second is fixed on the inner wall of semilune folder 17
Equipped with the second bolster 37;
Second bolster 37 is semilune and fixes half with the first activity semilune folder 10 and described first
The inner wall of month clevis part 11 is close to;
Second bolster, 37 material is silicon rubber.
Specifically, since the second activity semilune folder 16 and second fixes the inner wall and cable elbow-shaped of semilune folder 17
Head is in contact, therefore cable elbow-shaped head, the second activity semilune folder 16 and second fix the inner wall of semilune folder 17 with length
Time uses, and frayed degree is higher.Therefore it is fixed in semilune folder 17 in the second activity semilune folder 16 and second
The second bolster 37 is arranged in wall, and abrasion is placed to play the role of protection.
Using traditional manual type during cable elbow-shaped head is installed, the relative position of part can be caused to become
Change, prevents stress solid with semiconductor layer from effectively overlapping, to influence field distribution, cause the operation of cable elbow-shaped head hidden
Suffer from.Destruction will not be generated to cable elbow-shaped head and surrounding components using the cable elbow-shaped head mounting device of the application.Meanwhile second
Cushioning effect is played in the vibration that bolster 37 generates cable elbow-shaped head in installation and removal in the process, and then reinforces protection cable
Elbow-type head.
Further, the inner wall of the locating slot 35 is equipped with third bolster 38;
One end that second push-pull rod 21 is close to the movable block 6 is equipped with the 4th bolster 39;
4th bolster, 39 material is silicon rubber.
Specifically, the bottom of movable block 6 is located inside locating slot 35, and movable block 6 is connected with hydraulic device 4, hydraulic pressure dress
The push-and-pull connecting rod 22 for setting 4 drives movable block 6 to be slided along support link 3 by the first push-pull rod 20 and the second push-pull rod 21, to protect
It demonstrate,proves movable block 6 and the connection of the second push-pull rod 21 is closer, in the inner wall setting third bolster 38 of locating slot 35, increase friction
Power.Meanwhile cushioning effect is played in the vibration that third bolster 38 generates cable elbow-shaped head in installation and removal in the process, in turn
Reinforce protection cable elbow-shaped head
Further, the hydraulic pump 31 pumps for electronic double loop hydraulic.
Specifically, single loop refers to just that there are one the circuits of power supply for a load;Double loop refers to just a load
There are two the circuits of power supply.High situation is generally required power supply reliability, using double circuit power supply, it can be protected in this way
In power supply when having a power failure for some reason, another power supply can continue to power.Hydraulic pump 31 is pumped using electronic double loop hydraulic, is ensured
Hydraulic device 4 is avoided the occurrence of as possible during being promoted and choosing operation because single circuit power supply has a power failure for some reason so that electricity
Cable elbow-type head mounting device can not continue the case where operation.
Further, the installation cable elbow-shaped head method includes:
S100:Casing fixed ring 1 is fixedly connected with fixed block 5;

S600:Described sleeve pipe fixed ring 1 is detached with the ring main unit high-tension cable casing, the cable elbow-shaped head fixed ring
2 detach with the cable elbow-shaped head, complete installation.
It is the application cable elbow-shaped head installation procedure schematic diagram referring to Fig. 5.
Specifically, step S100, the casing fixed ring 1 that selection matches with ring main unit high-tension cable casing size, will cover
Pipe fixed ring 1 is fixedly connected by the first mounting hole 9 with fixed block 5 by the first connection bolt 13.It is solid to loosen casing by step S200
Determine the casing fixing bolt 7 of ring 1, the first activity semilune folder 10 is rotated around the first arc track 12, is lived so as to adjust first
The space size surrounded between 10 and first fixation semilune folder 11 of dynamic semilune folder.In turn, ring main unit high-tension cable
Casing can pierce into the first activity semilune folder 10 and first and fix the space surrounded between semilune folder.Then, it locks
Casing fixing bolt 7 so that casing fixed ring 1 is fixedly connected with ring main unit high-tension cable casing.Step 300, selection and cable
The cable elbow-shaped head fixed ring 2 that elbow-type head distribution cable access side size matches, passes through second by cable elbow-shaped head fixed ring 2
Connection bolt 19 is connected with movable block 6, and the second connection bolt 19 passes through the second mounting hole 15.Step S400, loosens cable elbow
The elbow-type head fixing bolt 14 of type head fixed ring 1, the second activity semilune folder 16 is rotated around the second arc track 18, to adjust
Whole second activity semilune folder 16 and second fixes the space size surrounded between semilune folder 17.Cable elbow-shaped head is matched
Electrical cables access side pierces into the second activity semilune folder 16 and second and fixes the space surrounded between semilune folder 17.Electricity
Cable elbow-type head distribution cable access side corresponds to the positions b in installation site i.e. Fig. 4.Then, locking elbow-type head fixing bolt 14, makes
Cable elbow-shaped head fixed ring 2 is obtained to be fixedly connected with cable elbow-shaped head distribution cable access side.Step S500 starts hydraulic device 4,
Carry out forward operation.During forward operation, the hydrostatic sensor 26 in hydraulic device 4 detects the hydraulic oil liquid in oil cylinder 24
Pressure, the distance between 27 detection cable elbow-type head of displacement sensor and ring main unit high-tension cable casing.Pass through microcomputer control
System adjusts the movable block 6 being connect with hydraulic device 4 close to ring main unit high-tension cable casing or far from ring main unit high-tension cable in time
The shift action size of casing, until cable elbow-shaped head is all promoted in ring main unit high-tension cable casing.Step S600, casing
Fixed ring 1 is detached with ring main unit high-tension cable casing, and cable elbow-shaped head fixed ring 2 is detached with the cable elbow-shaped head, completes peace
Dress.
