Principle of operation
Before an operator climbs the ladder, the clamping holes 15 in the middle of the clamping piece 14 above the auxiliary upper part of the ladder are aligned with handrails on two sides of the tower crane ladder, the lower pressing plate 33 is placed on the nearest one-stage pedal column, and then the lower pull belt 7 and the lantern ring 8 are utilized for powering the motor in the motor box 9 to clamp the clamping piece 14, and meanwhile the ladder wheel 21 rotates to put on the upper one-stage pedal column of the tower crane ladder. After the fixing, the pull belt 7 is loosened temporarily, and the safety rope on the operator is hung on the handle 3 outside the auxiliary housing 2 of the cat ladder, and at the moment, the heavy objects on the body can be hung on the handle together. The pull strap 7 under the ladder support is then pulled tight, and the two feet are each fitted with a collar 8 over the feet. When an operator starts climbing the tower crane, each time the foot is lifted, power is provided for a motor in the motor box 9, so that clamping pieces 14 on two sides are clamped and confirmed once, and meanwhile, the climbing wheel 21 rotates;
when the ladder wheel 21 rotates, the next ladder claw 24 is hung upwards on the pedal column of the higher stage, at this time, as the ladder claw 24 positioned above buckles one pedal column, the pressing block 48 arranged below the second cylindrical bulge 26 is pressed into the second cylindrical bulge 26 to enable the locking rod 42 to rise, so hydraulic oil in the locking hydraulic pipe 45 is extracted to enable the locking blocks 46 arranged on two sides of the locking rotating wheel 44 to extend out to form fixed connection with the ladder wheel 21, and meanwhile, the other three ladder claws 24 are not lifted due to the fact that the locking columns 42 in the inner part are not lifted, so that the corresponding locking columns 46 do not extend in situ to enable the ladder claw 24 to rotate; meanwhile, the hydraulic rod 30 below the auxiliary climbing ladder moves, the auxiliary climbing ladder is pushed upwards by using the supporting force generated by pressing the pressing plate 33 on the pedal column of the tower crane ladder, the hydraulic rod 30 and the pressing plate 33 below the auxiliary climbing ladder are retracted after the auxiliary climbing ladder ascends to a certain height, and the pressing plate 33 can be opened to avoid colliding with the pedal column above the auxiliary climbing ladder in the upward movement process, so that the auxiliary climbing ladder can ascend once;
in the ascending process, a motor 39 is arranged above the arc chute 28 fixed on the inner side of the auxiliary climbing ladder casing 2 to continuously operate, the half gear 38 which drives the arc chute 28 to be close to one side of the casing 2 rotates to push out the rectangular scraping claw 34, when the half gear 38 rotates by a certain angle, the two are disengaged, the arc chute 29 is pulled back under the action of the closed hydraulic rod 40, the arc chute 35 contacts a pedal column clamped by the climbing ladder wheel in the recycling process, the climbing ladder on two sides is assisted to simultaneously carry out scraping activities, one-time scraping and cleaning can be completed, and mud blocks and dust residues on the surface of the pedal column are reduced.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
