The climbing assembly 200 consists of two sets of longitudinal bars 201, one set of transverse bars 202 and multiple sets of attachment bars 203, both sets of longitudinal bars 201 being provided at both ends of the outer wall of the transverse bar 202, with multiple sets of attachment bars 203 equally at one end the outer wall of the two sets of longitudinal bars 201, the role of the fixing bar 203 being to fix the transversal bar 202 and the tower 100.

A riser channel 201a is provided at an end of the outer wall of the two sets of longitudinal rods 201 remote from the mounting bar 203, both ends of the inner wall of the above-mentioned riser channel 201a are fixedly connected to the limit blocks 201b, and the seat belt connector 301 is slidably connected within the riser channel 201a , wherein the seat belt connector 301 comprises a first slider 301a and a spring block 301b, both ends of the outer wall of the first slider 301a are provided with a fourth inner slot 301a-1, wherein an end surface of the outer wall of the spring block 301b is a ramp, the bottom surface of the spring block 301b is a horizontal end surface, one end of the outer wall of the spring block 301b being provided with a third spring 301b-1, the other end of the third spring 301b-1 being fixed to the inner wall of the fourth inner slot 301a-1 of the first slider 301a is connected, wherein the spring block 301b is slidably connected to the fourth inner slot 301a-1 of the first slider 301a, the outer wall of the seat belt connector 301 is provided at one end with a limit slider 302, the shape of the limit slider 302 is a cube, the Limiting slide 302 closely adapts to the inner wall of the riser channel 201a. The riser passage 201a is used as a slideway of the first slider 301a. The role of the restraining block 201b is to restrain the seat belt connector 301 to prevent the seat belt connector 301 from slipping inside the riser channel 201a. Due to the slidable connection of the spring block 301b within the fourth inner slot 301a-1 of the first slider 301a and the ramp of an end surface of the outer wall of the spring block 301b when the seat belt connector 301 rises within the riser channel 201a and when the spring block 301b in contact with the limit block 201b comes, the spring block 301b receives a pushing force so that the spring block 301b shrinks within the fourth inner slit 301a-1. At this time, the restriction block 201b no longer restricts the seat belt connector 301. When the seat belt connector 301 moves upward, since the spring block 301b is provided with a third spring 301b-1 at one end of the outer wall, the spring block 301b pops out from the second inner slot 301a-1 by the elastic force of the third spring 301b-1 . Since the bottom of the spring block 301b is a horizontal end surface, the spring block 301b cannot pass through the restriction block 201b and move downward. The role of the limit slider 302 is to cooperate with the riser channel 201a so that the seat belt connector 301 does not offset or roll within the riser channel 201a.

After that, pull the seat belt up until the seat belt connector 301 contacts the limit block 201b closest to the bottom inside the riser channel 201a and continue to pull it up. At this time, the safety rope 305 drives the seat belt connector 301 through the protection pin 304 and the limit slider 302 to move up. Since an end surface of the outer wall of the spring block 301b is a ramp, and the spring block 301b is slidably connected within the fourth inner slot 301a-1, when the seat belt connector 301 receives a pushing force from the ramp, this causes the spring block 301b to be at both ends of the outer wall of the first slider 301a slides within the fourth inner slot 301a-1 so that the seat belt connector 301 can pass the limit block 201b, when the seat belt connector 301 has passed the limit block 201b, the third spring 301b-1 causes the spring block 301b out of the fourth inner slot 301a -1 of the first slider 301a pops out because the spring block 301b is fixedly connected to a third spring 301b-1 at one end of the outer wall. Since the bottom of the spring block 301b is a horizontal end face, when the seat belt connector 301 moves down within the riser channel 201a, it is blocked by the limit block 201b and cannot move down, preventing the personnel from falling when climbing the tower falls down.

The pressing slot 202a serves to accommodate the pressing block 202b. The action of the second spring 202b-1 makes it possible to support the press block 202b without applying a force to the press block 202b, so that the ramp of the press block 202b is not in contact with the first connection block 201d-2, causing the sliding limit block 201d under under normal conditions, by means of the thrust force provided by the first spring 201d-1, it causes the first link block 201d-2 to push the slide limit block 201d, so that the slide limit block 201d is laid horizontally in the drop channel 201c, thereby preventing the seat belt connector 301 in down the fall channel 201c.

Working principle: when the staff has to dismount, they put on a seat belt. The seat belt connector 301 and the limit slider 302 are arranged at both ends of the seat belt to slide in the drop channel 201c at the top of the longitudinal bar 201. The seat belt connector 301 and the limit slider 302 slide out of the drop channel 201c at the top of the longitudinal bar 201 due to gravity and are blocked by the sliding limit block 201d placed horizontally on top of the drop channel 201c. If the personnel use both hands to hold the press block 202b at both ends on the same set of crossbars during the descent 202, since an end surface of the outer wall of the pressing block 202b is a ramp, the pressing block 202b pushes the first connecting block 201d-2 to slide within the first inner slot 201c-1, with the sliding limit block 201d sliding through the first connecting block 201d-2 is brought. To do this, the slide limiter block 201d is received within the first inner slot 201c-1 so that it no longer blocks the seat belt connector 301 within the drop channel 201c. The seat belt connector 301 falls onto the sliding limit block 201d of the next layer due to gravity and so on until the operator descends to the bottom layer and the seat belt connector 301 is pulled off the bottom of the drop channel 201c. With the cooperation of the riser channel 201a and fall channel 201c in the longitudinal bars 201 and the protection assembly 300 in this embodiment, the personnel does not have to frequently lift and then buckle the seat belt during the climbing operation, which saves the operator a lot of man-hours and thereby improves the climbing efficiency. And through the structural adjustment of the press blocks 202b at both ends of the crossbar 202, the staff must complete the process of descending with both hands on the same crossbar 202 to complete the dismounting, so that the staff dismounting on the straight ladder is more standardized to complete the further guarantee the personal safety of the operator.

The role of the second inner slot 201e is to receive the rotating rod 201f and the connecting rod 201f-1, and the role of the first slide groove 201e-1 is to serve as a slideway of the second slider 303.

The second inner slot 201e is rotatably connected to a pivot rod 201f at the top, the pivot rod 201f having an inverted "L" shape, the platform cover 401 is rotatably connected to the top of the deceleration platform 101, the platform cover 401 has through slots 401a on both ends of the outer wall, the pivot rod 201f passing through the platform cover 401 via through slot 401a, the pivot rod 201f serving to cooperate with the through slot 401a at one end of the outer wall of the platform cover 401 to recognize that the platform cover 401 has two states of the Has locking and opening.

The rotating rod 201f is provided with a connecting rod 201f-1 on the outer wall, the connecting rod 201f-1 being closely fitted to the inner wall of the second inner slot 201e, the connecting rod 201f-1 having a second sliding groove 201f-1a and a third sliding groove 201f-1b is provided on the outer wall, and the second slider 303 is slidably connected to the inner walls of the second sliding groove 201f-1a and the third sliding groove 201f-1b. In the normal state (ie, the locked state), the bottom of the third slide groove 201f-1b with the first slide groove 201e-1 is close to the drop channel 201c and the bottom of the second slide groove 201f-1a with the first slide groove 201e-1 is close, respectively of the riser channel 201a continuously connected. In the open state (i.e. the in 2 state shown), the top of the second slide groove 201f-1a falls horizontally with the first slide groove 201e-1 near the riser channel 201a, and the top of the third slide groove 201f-1b horizontally with the first slide groove 201e-1 near the fall channel 201c, respectively together, the role of the second sliding groove 201f-1a and the third sliding groove 201f-1b is when the second slider 303 slides within the first sliding groove 201e-1 so that the second slider 303 moves due to the limitation of the seat belt connector 301 and the Limit slider 302 can only move up or down, or move up or down by the second slider 303, so that the rotating rod 201f rotates, whereby the purpose of opening or locking the platform cover 401 is achieved.
