[0043] In the present application, the tower body 1 is a steel structure cylindrical tower body 1; referring to Figure 13 , Figure 13 A cross-sectional view showing the cooperation of the angle iron 4 and the fixed bin 3, in some other embodiments, when the tower body 1 is an angle iron tower, there are generally four angle irons 4, and the fixed bin 3 is welded on the outer side wall of one side of one of the angle irons 4, the length extension direction of the fixed bin 3 is in the same direction as the length extension direction of the angle iron 4, and the worker climbs along the pole climbing 2 extending out of the outer side of the angle iron 4.

[0044] Referring to Figures 5-9 , the first limiting component 36 includes a guide plate 361 and a limiting block 362 connected to one end of the guide plate 361, the end of the guide plate 361 away from the limiting block 362 is rotationally connected to the groove wall of the first sliding groove 311 away from the limiting plate 34, and the limiting block 362 and the groove wall of the first sliding groove 311 away from the limiting plate 34 are connected by a resilient member 363, the elastic force of the resilient member 363 is used to make the end of the guide plate 361 close to the limiting block 362 abut against the limiting plate 34, the side of the guide plate 361 away from the limiting block 362 forms a first guide surface 3611, and the top of the limiting block 362 forms a limiting surface 3621; the positioning component 35 includes a guide member 351 embedded in the first sliding groove 311 and a hand-held rod 352 connected to the guide member 351 and extending out of the first sliding groove 311, and a hanging ring 353 is connected to the end of the hand-held rod 352 away from the guide member 351, the guide member 351 has a second guide surface 3511 cooperating with the first guide surface 3611.

[0045] When the worker climbs upward, the second guide surface 3511 of the positioning component 35 abuts against the first guide surface 3611 and presses the guide plate 361, the guide plate 361 presses the resilient member 363 through the limiting block 362, so that the end of the guide plate 361 close to the limiting block 362 moves to the groove bottom of the first sliding groove 311, thus the positioning component 35 can slide upward along the first guide surface 3611 until it moves above the guide plate 361, the guide plate 361 abuts against the limiting plate 34 under the reaction force of the resilient member 363, at this time, even if the guide member 351 slides downward, the guide member 351 will be limited on the limiting surface 3621 of the limiting block 362, the end of the guide plate 361 is rotationally connected to the groove bottom of the first sliding groove 311, and the limiting block 362, the guide plate 361, the groove bottom of the first sliding groove 311 and the limiting plate 34 form a stable support structure, which limits the downward sliding of the guide member 351, and realizes the function of one-way locking.

[0046] Referring to Figures 9-12The second limiting assembly 37 comprises a plurality of stop blocks 371 staggered on both sides of the length extension direction of the second sliding groove 321, and the stop blocks 371 are used to block the positioning member 35 in the length extension direction of the second sliding groove 321. In the length extension direction of the second sliding groove 321, the adjacent two stop blocks 371 have a sliding gap 372 perpendicular to the length extension direction of the second sliding groove 321 and facilitating the movement of the positioning member 35.

[0047] When the worker climbs down, the guide 351 of the positioning member 35 is blocked by the stop block 371 when moving downward, avoiding the free falling of the guide 351. The plurality of stop blocks 371 are staggered left and right in the vertical direction, so that the positioning member 35 moves downward in an “S” shape, that is, the worker climbs down a distance, and the hand holding rod 352 of the positioning member 35 can be easily adjusted left and right by the worker's hand, which is simple to operate. The worker can always hold the hand holding rod 352 of the positioning member 35 with one hand and hold the hand and foot rod 22 with the other hand.

[0048] In the present application, the limiting plate 34 of the uplink bin 31 and the downlink bin 32 has a long slot matched with the first sliding groove 311 and the second sliding groove 321. The long slot of the limiting plate 34 of the uplink bin 31 extends in the vertical direction, and the long slot of the limiting plate 34 of the downlink bin 32 extends in an “S” shape.

[0049] The adjacent two stop blocks 371 on the same side of the length extension direction of the second sliding groove 321 have a gap 372, and the stop block 371 on the other side of the second sliding groove 321 partially extends into the gap 372.

[0050] In this way, when the positioning member 35 moves downward from top to bottom, the part of the stop block 371 extending into the gap 372 can effectively block the positioning member 35 from falling over many stop blocks 371 under the action of gravity, causing unnecessary safety risks. Especially when the edge of the stop block 371 is worn after a long time of use, the worn part is easy to guide the stop block 371, or the worn part has a larger gap, which is easy to make the positioning member 35 fall over the next layer of stop blocks 371.

[0051] In some embodiments, the side close to each other of the two adjacent stop blocks 371 on the left and right sides can be provided with an infrared detector 373, and the infrared detector 373 is used to detect the distance between the two stop blocks 371. Because wear will change the distance between the two adjacent stop blocks 371, the wear of the stop block 371 can be detected, and the detection data of the infrared detector 373 is transmitted to the terminal device on the ground, so that the wear of the stop block 371 of the entire downlink bin 32 can be monitored, and maintenance can be performed in advance.

[0052] The top surface of the stopper 371 is connected to a friction layer.

[0053] The sidewall of the bottom of the upgoing bin 31 or the downgoing bin 32 is provided with an inspection groove 33 communicating with the circulating channel and used for sliding out the positioning member 35. The positioning member 35 can be slid out of the circulating channel through the inspection groove 33, so that the positioning member 35 can be replaced or inspected.

[0054] The first sliding groove 311 and the second sliding groove 321 are respectively located on the side of the support rod 21 away from the hand and foot rod 22. In this way, the safety rope of the safety belt can be prevented from being wound on the hand and foot rod 22 during the climbing of the worker, and the position where the safety rope is connected to the safety belt can be selected as the two sides of the waist of the worker or the back of the waist.

[0055] The elastic member 363 is a spring.

[0056] The guide plate 361 is connected to the groove wall of the first sliding groove 311 through the ball hinge 364.

[0057] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradiction). In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described.
