[0028] The clamping block mechanism 3 includes a threaded rod 301 rotatably connected to the arc bottom plate 1, one end of the threaded rod 301 away from the arc bottom plate 1 is fixedly connected to the rotating handle 302, the threaded rod 301 is threadedly connected to the feed plate 303, the feed plate 303 is fixedly connected to two feed rods 304, the two feed rods 304 are symmetrically arranged on the feed plate 303, the feed rod 304 passes through the arc bottom plate 1, the feed rod 304 and the arc bottom plate 1 are slidably connected, and one end of the feed rod 304 away from the feed plate 303 is fixedly connected to the rubber clamping block 305.

[0029] Specifically, rotating the handle 302 will drive the threaded rod 301 to rotate, and the threaded rod 301 can drive the feed plate 303 to move. The feeding of the feed plate 303 can drive the feed rod 304 to feed, thereby driving the rubber block 305 to feed, so that the rubber block 305 contacts with devices such as power poles, so as to realize direct contact between the arc bottom plate 1 and devices such as power poles, thereby ensuring the stability of the arc bottom plate 1.

[0030] The movable plate mechanism 4 includes an arc-shaped slide groove 401 opened on the arc-shaped bottom plate 1, a movable plate 402 is provided on the arc-shaped slide groove 401, the movable plate 402 and the arc-shaped bottom plate 1 are slidingly connected, the movable plate 402 is fixedly connected to the motor base 403, the motor base 403 is fixedly connected to the motor 404, the output shaft of the motor 404 is fixedly connected to the first gear 405, the first gear 405 is meshed with the second gear 406, and the second gear 406 is fixed on the arc-shaped bottom plate 1.

[0031] Specifically, the motor 404 is turned on, and the output shaft of the motor 404 rotates to drive the first gear 405 to rotate. Since the first gear 405 and the second gear 406 are meshed, the movable plate 402 can move along the arc-shaped slide groove 401 to enable the movable plate 402 to surround the power pole.

[0032] The one-way rotating block mechanism 5 includes a rotating seat 501 fixed on the moving plate 402, the rotating seat 501 is rotatably connected to the central axis 502, the central axis 502 is fixedly connected to a plurality of clamping rod seats 503, the clamping rod seats 503 are rotatably connected to the clamping rod 504, a spring 505 is fixedly connected between the clamping rod 504 and the central axis 502, a rotating sleeve 506 is provided outside the central axis 502, the rotating sleeve 506 is rotatably connected to the rotating seat 501, a plurality of ratchet teeth 507 are fixedly connected inside the rotating sleeve 506, the rotating sleeve 506 is fixedly connected to the rotating block 508, and the rotating block 508 is fixedly connected to the multi-stage hydraulic telescopic cylinder 7. The clamping wheel mechanism 6 includes a hydraulic telescopic rod 601 fixed on the moving plate 402, the hydraulic telescopic rod 601 is fixedly connected to the wedge block 602, the central axis 502 passes through the rotating seat 501 and is rotatably connected to the rotating seat 501, the central axis 502 is fixedly connected to the clamping wheel 603, and a plurality of wedge grooves 604 are provided in the circumference of the clamping wheel 603. The protection frame mechanism 8 includes a protection bottom shell 801 fixed on the multi-stage hydraulic telescopic cylinder 7, and the four corners of the protection bottom shell 801 are fixedly connected to the vertical rod 802, and the vertical rod 802 is fixedly connected to the protection frame 803. The limiting clamping ring mechanism 9 includes a connecting rod 901 fixed on the protection bottom shell 801, and the connecting rod 901 is fixedly connected to the semicircular ring shell 902, and the semicircular ring shell 902 is provided with a rotating ring groove 903, and a semicircular ring 904 is provided in the rotating ring groove 903. The semicircular ring 904 is slidably connected to the semicircular ring shell 902, and the semicircular ring shell 902 is threadedly connected to the locking bolt 905, and the semicircular ring 904 is provided with a limiting hole, and the locking bolt 905 passes through the limiting hole.

[0033] Specifically, the locking bolt 905 is turned to release the limit on the semicircular ring 904, and the semicircular ring 904 is adjusted so that the power pole is placed in the semicircular ring shell 902 and the semicircular ring 904. At this time, the locking bolt 905 is turned so that the locking bolt 905 passes through the limit hole to achieve the relative position fixation of the semicircular ring shell 902 and the semicircular ring 904. At this time, if it is necessary to protect the bottom shell 801 from rising, the multi-stage hydraulic telescopic cylinder 7 is opened to extend the multi-stage hydraulic telescopic cylinder 7. By opening the hydraulic telescopic rod 601, the wedge block 602 is inserted into the wedge groove 604 to achieve the limited rotation of the clamping wheel 603 and the central axis 502. At this time, under the action of the clamping rod 504, the rotating sleeve 506 can be rotated in one direction, that is, the multi-stage hydraulic telescopic cylinder 7 is rotated upward to avoid the multi-stage hydraulic telescopic cylinder 7 from falling when the multi-stage hydraulic telescopic cylinder 7 fails. Due to the limit of the clamping rod 504, the multi-stage hydraulic telescopic cylinder 7 can be prevented from shortening, thereby ensuring the safety of power installation.

[0034] In addition, if it is necessary to lower the protective bottom shell 801, the hydraulic telescopic rod 601 is opened so that the wedge block 602 is no longer inserted in the wedge groove 604, thereby releasing the restricted rotation of the clamping wheel 603 and the central axis 502, thereby releasing the unidirectional rotation of the multi-stage hydraulic telescopic cylinder 7. At this time, the multi-stage hydraulic telescopic cylinder 7 is opened to shorten the multi-stage hydraulic telescopic cylinder 7, so that the protective bottom shell 801 can be lowered along the power pole.

[0035] Example 2, continue to refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 In an embodiment of the present invention, the contact wheel mechanism 10 includes a contact wheel shaft 1001 rotatably connected to the semicircular ring shell 902, and one end of the contact wheel shaft 1001 away from the semicircular ring shell 902 is fixedly connected to a contact wheel seat 1002, and the contact wheel seat 1002 is rotatably connected to the contact wheel 1003.

[0036] Specifically, the contact wheel 1003 can directly contact the power pole, thereby preventing the limiting clamping ring mechanism 9 from directly contacting the power pole.

[0037] During the implementation of the present invention, the mounting frame is first moved to the specified position by the roller mechanism 2, at which time the power pole and other fixing devices are placed between the two clamping block mechanisms 3. At this time, the clamping block mechanism 3 is used to connect with the power pole and other fixing devices, and then the limit of the clamping wheel mechanism 6 on the one-way rotating block mechanism 5 is released. At this time, the power pole is placed inside the limit clamping ring mechanism 9 by adjusting the limit clamping ring mechanism 9, and personnel can stand in the protective frame mechanism 8. At the same time, the one-way rotating block mechanism 5 is limited to one-way rotation by the clamping wheel mechanism 6. At this time, opening the multi-stage hydraulic telescopic cylinder mechanism 7 can drive the protective frame mechanism 8 to rise. In addition, when the multi-stage hydraulic telescopic cylinder mechanism 7 fails, the protective frame mechanism 8 can also be prevented from rotating downward to ensure the safety of personnel on the protective frame mechanism 8. Opening the moving plate mechanism 4 can enable the protective frame mechanism 8 to be installed around the power pole. If the protective frame mechanism 8 needs to be lowered, the limit of the one-way rotating block mechanism 5 by the clamping wheel mechanism 6 is released, so that the multi-stage hydraulic telescopic cylinder mechanism 7 shrinks, thereby causing the protective frame mechanism 8 to descend.

[0038] The present invention can achieve connection with the power pole by setting a clamping block mechanism 3, ensure the stable connection of the arc bottom plate 1, can drive the protection frame mechanism 8 to move around the power pole through the moving plate mechanism 4, can drive the protection frame mechanism 8 to rise and fall through the multi-stage hydraulic telescopic cylinder 7, can achieve connection with the power pole through the limiting clamping ring mechanism 9, and can avoid direct contact between the limiting clamping ring mechanism 9 and the power pole through the contact wheel mechanism 10, which will cause excessive friction and damage to components, thereby improving the safety of power installation.
