Corresponding annular magnet.A lashed cable slot 4 is equipped on the lateral surface of two sliding bars and on the outside of support tube.
The lateral surface of support tube is equipped with two strip pilot holes 6 axially extending along support tube, two strip guiding
Hole is distributed along the axial direction of support tube.Sliding bar and strip pilot hole correspond.The lateral surface of sliding bar is equipped with operating stick
5, one end of operating stick passes through corresponding strip pilot hole and is located at the outside of support tube.Pass through between operating stick and sliding bar
It is threadedly coupled.
Clamping screw and sliding bar correspond.Clamping screw is arranged on support tube for fixing corresponding sliding bar.
A clamping screw in two clamping screws is close to one end of support tube, and another clamping screw is close to the another of support tube
End.
Anti- cable dropping device is located at the outside of support tube.
Anti- cable dropping device include the first sliding sleeve 8.1 for being slidably located on sliding bar with the second sliding sleeve 8.2, connect
The sliding sleeve connecting rod 8.3 of one sliding sleeve and the second sliding sleeve is arranged on the lateral surface of sliding bar and the limit axially extending along sliding bar
Slot 8.5, is arranged in the first sliding sleeve end face the limited block 8.6 for being arranged on the medial surface of the first sliding sleeve and matching with limiting slot
On countercheck rod 8.4, be fixed on the lateral surface of sliding bar and determine absorption between the first sliding sleeve and the second sliding sleeve
Magnet 8.8 is arranged in towards the first moving magnet 8.9 determined on the first sliding sleeve end face of adsorption magnet and is arranged on the second sliding sleeve
Second moving magnet 8.7.
In a ring, and the second moving magnet is set on the second sliding sleeve second moving magnet.Second moving magnet and close second moves
The annular magnet of magnet cooperates.
In same anti-cable dropping device, the second sliding sleeve is between the first sliding sleeve and support tube, sliding sleeve connecting rod and blocking
Bar is located at the opposite sides of sliding bar, determines adsorption magnet between the first moving magnet and the second sliding sleeve.
In same anti-cable dropping device, the bottom surface of lashed cable slot is close to sliding sleeve connecting rod, and the notch of lashed cable slot is close to countercheck rod.
Countercheck rod is between the first sliding sleeve and the second sliding sleeve, and countercheck rod is along the axially extending of sliding bar.Countercheck rod is used
Deviate from the aerial condutor that prevention is placed in lashed cable slot by the notch of lashed cable slot.
For the first end of limiting slot close to support tube, the second end of limiting slot is located at the phase of the first end of limiting slot with support tube
To two sides.
As shown in Fig. 2, when limited block is against in the second end of limiting slot, the axial direction of countercheck rod and lashed cable slot in sliding bar
On be in staggered distribution.
The telescoping cable spacing expander of the present embodiment it is specifically used as follows:
First, as shown in Figure 1 and Figure 2, drives sliding bar to slide in support tube by operating stick, determine until the second sliding sleeve is against
The end face of annular magnet, and until limited block is against in the second end of limiting slot, at this point, the second moving magnet and annular magnet
It is attracted, and countercheck rod is in staggered distribution in the axial direction of sliding bar with lashed cable slot；
Second, an aerial condutor in two aerial condutors 9 is placed in one in a lashed cable slot, another aerial condutor is set
In in another lashed cable slot；
Third, as shown in figure 3, driving corresponding sliding bar toward pull-out outside support tube by one of operating stick, in this mistake
Cheng Zhong determines adsorption magnet 8.8 and goes together with sliding bar one far from the movement of support tube direction, and due to the second moving magnet and annular magnetic
Iron is attracted, thus the first sliding sleeve is remained stationary with the second sliding sleeve, when determining adsorption magnet and being against on the first moving magnet, adsorbs magnetic surely
Iron and the first moving magnet are attracted, and countercheck rod 8.4 will stop the notch of lashed cable slot, are placed in lashed cable slot by countercheck rod prevention
Aerial condutor by lashed cable slot notch deviate from；
After determining adsorption magnet and being against on the first moving magnet, anti-cable dropping device will be gone together with sliding bar one far from support tube side
Sliding bar is locked in support tube by clamping screw after sliding bar sets length toward pull-out outside support tube to movement
It is upper；
Then, it drives corresponding sliding bar toward pull-out outside support tube by another operating stick, in this process, adsorbs magnetic surely
Iron 8.8 is gone together with sliding bar one far from the movement of support tube direction, and since the second moving magnet and annular magnet are attracted, thus the
One sliding sleeve is remained stationary with the second sliding sleeve, when determining adsorption magnet and being against on the first moving magnet, determines adsorption magnet and the first dynamic magnetic
Iron is attracted, and countercheck rod 8.4 will stop the notch of lashed cable slot, by countercheck rod prevent the aerial condutor that is placed in lashed cable slot by
The notch of lashed cable slot is deviate from；
After determining adsorption magnet and being against on the first moving magnet, anti-cable dropping device will be gone together with sliding bar one far from support tube side
Sliding bar is locked in support tube by clamping screw after sliding bar sets length toward pull-out outside support tube to movement
It is upper.
The telescoping cable spacing expander of the present embodiment can not only strut two aerial condutors, be that the upright bar of electric pole is made
Industry provides enough working spaces, and driven by operating stick corresponding sliding bar toward during pull-out outside support tube,
Aerial condutor is blocked bar and is limited in lashed cable slot, and aerial condutor is avoided to be deviate from by the notch of lashed cable slot, to stablize, is reliable
Two aerial condutors are strutted, and the operation for strutting two aerial condutors is convenient, fast.
