detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:

A locking ladder suitable for steel pipe poles, comprising a plurality of spikes 1, an outer tube 4, a connecting rod 5 and a locking mechanism 9, the connecting rod 5 is provided with a plurality of support rings 7, the connecting rod 5 and The peripheral surface of the support ring 7 is vertical. Both the connecting rod 5 and the supporting ring 7 are located inside the outer tube 4, the outer peripheral surface of the supporting ring 7 is in clearance fit with the inner wall of the outer tube 4, and the tube wall of the outer tube 4 is provided with A plurality of pipe wall openings 2, one end of the plurality of foot nails 1 passes through one of the pipe wall openings 2 and is respectively movably connected with the connecting rod 5, and the pipe wall of the outer pipe 4 is relatively provided with multiple For the coaxial locking hole 10, the locking mechanism 9 includes a rod-shaped part 8 and a rope 11, the rod-shaped part 8 is in clearance fit with the locking hole 10, and the connecting rod 5 is provided with multiple A through hole 13, the central axis of the through hole 13 is perpendicular to the axis of the connecting rod 5. The pin 3 is connected between the foot nail 1 and the connecting rod 5 .

The flexible cable 11 has two sections, and one end of the two sections of flexible cable 11 is respectively connected to one end of the rod-shaped part 8 .

The lifting of the connecting rod 5 can be realized by the lifting connecting rod driving mechanism 6 . When the connecting rod 5 descends to a certain position, the foot nail 1 is in a horizontal state, and a through hole 13 on the connecting rod 5 is aligned with a pair of locking holes 10. At this time, the rod-shaped part 8 of the locking mechanism 9 is passed through The through hole 13 and a pair of locking holes 10 prevent the connecting rod 5 from moving up and down, and the connecting rod 5 is fixed. The foot spike 1 is fixed in a horizontal state, and now the foot spike 1 is in a climbable state, and the staff can stand on the foot spike 1 and climb upwards.

When the connecting rod 5 rose to a certain position, the foot nail 1 was in the maximum inclined state, the outer end of the foot nail 1 drooped, and a through hole 13 on the connecting rod 5 was aligned with a certain pair of locking holes 10. The rod-shaped part 8 of the stop mechanism 9 passes through the through hole 13 and the pair of locking holes 10, so that the connecting rod 5 can no longer move up and down, and the connecting rod 5 is fixed. At this moment, the foot spike 1 is in a fixed inclined state, that is, in a state of being unable to climb, and irrelevant personnel cannot stand on the inclined foot spike 1 . The potential safety hazard caused by unrelated personnel climbing the ladder is avoided.

When the locking ladder suitable for steel pipe rods is in an incapable state of climbing, lock the two sections of flexible ropes 11 with a lock 12, so that the rod-shaped part 8 and the two sections of flexible cables 11 form a closed ring, Lock the connecting rod 5 and the foot nail 1, so as to completely prevent irrelevant personnel from climbing the ladder.
