Description

[0002] The inspection and maintenance of pole-mounted switches is an inevitable task for power workers in their daily lives. Pole-mounted switches installed at high altitudes require regular inspection and maintenance.

[0003] When inspecting the pole switch, the operator usually uses a ladder set up at the bottom of the pole for the operator to climb. When the operator climbs to the appropriate position, he needs to stand on the upper end of the ladder to perform the inspection work. The operator will move while performing the inspection work, and the ladder will shake during the movement, resulting in poor stability of the ladder during use, which may easily cause safety hazards. Secondly, when there is a distribution box at the bottom of the pole, the distribution box interferes with the installation of the ladder, making it inconvenient to use. For this reason, we propose an auxiliary device for inspecting the pole switch. Summary of the invention

[0043] Working principle of the present invention:

[0044] When in use, when the pole switch is repaired, when the pole switch is installed on two electric poles and the distance between the two electric poles is far, the two swing boxes 411 are rotated so that the angle between the two swing boxes 411 is 180 degrees at the maximum, the movable box 412 is moved inside the swing box 411, and the sliding plate 413 is moved inside the movable box 412. The sliding plate 413 moves with the auxiliary block 421, and the auxiliary block 421 moves with the sliding block 422, so that the sliding block 422 is attached to the side of the electric pole, and the electric pole is tightly held by the mutual compression between the sliding block 422 and the clamping block 428, and then the installation box 3 is rotated, and the installation box 3 rotates with the swing block 511, and the swing block 511 rotates with the fixed support block 512, and then the swing block 511 is swung to make the first connecting cross bar 513 lean against the electric pole for the operator to climb;

[0045] When there is only one electric pole and there is a distribution box at the bottom of the electric pole, there is no position at the bottom of the electric pole where the clamping and fixing structure can be attached. At this time, the movable box 412 can be taken out from the inside of the swing box 411. First, the clamping block 428 and the sliding block 422 are used to hold the electric pole tightly above the distribution box. Then, the fixed support block 512 is rotated to make the first connecting cross bar 513 stick to the electric pole. At this time, the first connecting cross bar 513 is in an inclined state. Then, the movable box 412 is moved so that the movable box 412 drives the first slider 414 to move to the position of the fifth threaded cavity 521 and aligns the second threaded cavity 416 with the fixed support block 512. The movement of the movable box 412 is constrained by screwing the third locking threaded column 522 into the inside of the fifth threaded cavity 521 and penetrating into the inside of the second threaded cavity 416, so as to allow the arch operator to climb.

[0046] When there is no position on the electric pole for the clamping and fixing structure to be attached, the two swing boxes 411 are swung so that the two swing boxes 411 are cross-distributed, and then the first telescopic rod 426 is started, and the sliding block 422 is moved downward by the first telescopic rod 426 so that the bottom of the sliding block 422 contacts the ground. At this time, the mounting plate 1 and the two sliding blocks 422 are distributed in a triangle, and the fourth threaded column 525 is rotated to separate the fourth threaded column 525 from the inside of the sixth threaded cavity 524, and the sliding rod 515 can be pulled out from the inside of the second slide groove 514 to separate the sliding rod 515 from the fixed support block 512, and the upper ends of the two sliding rods 515 are placed in the interior of the connecting block 526, so that the position of the sixth threaded column 527 corresponds to the position of the sixth threaded cavity 524, and the sliding rod 515 is constrained by screwing the fourth threaded column 525 into the inside of the sixth threaded column 527 and the sixth threaded cavity 524 so that the sliding rod 515 supports the fixed support block 512, thereby providing a climbing environment for the arch operator.
