[0045] Working principle of the present invention:

[0046] When in use, when the user needs to climb upward for construction, rotate the positive and negative screw rod 201. The positive and negative screw rod 201 drives the fixed plates 202 to approach each other. The fixed plates 202 drive the clamping plates 203 to approach each other. At the same time, the fixed plates 202 slide on the surface of the first fixing rod 302, and the first fixing rod 302 plays a limiting role on the fixed plates 202. When the clamping plates 203 drive the rollers 204 to contact the climbing frame 1, the user can climb upward. When the user feels a sense of falling, since the locking rubber block 403 always contacts the climbing frame 1, and at the same time the second fixing rod 402 forms a certain angle with the climbing frame 1, the locking rubber block 403 is clamped with the climbing frame 1, so that the second fixing rod 402 contacts the clamping plate 203 through the fixing column 401 to complete the locking, thereby preventing the user from falling and avoiding the occurrence of danger.

[0047] In summary, for the climbing device for UHV transmission line construction, through the combined use of the climbing frame 1, the clamping mechanism 2, the positive and negative screw rod 201, the fixed plates 202, the clamping plates 203, the rollers 204, the limiting mechanism 3, the first fixing block 301, the first fixing rod 302, the second fixing block 303, the locking structure 4, the fixing column 401, the second fixing rod 402, the locking rubber block 403, the bearing 5, the spring 6, the rotating disk 7 and the arc-shaped hanging plate 8, the problems that the existing climbing device for UHV transmission line construction is not convenient to move upward during use and when the user accidentally falls, the hook cannot exert a pulling force, thus causing danger are solved.
