Example 2
Embodiment 2 is a modified structure of embodiment 1, and is different from embodiment 1 in that: as shown in fig. 3, a masonry platform anti-falling device 531 is respectively and fixedly arranged on the supporting bodies 520 of the masonry platform 510; the outer wall of the tower body 220 is respectively provided with a brake plate 260 corresponding to each masonry platform anti-falling device 531; the two masonry platform anti-falling devices 531 are arranged at an angle of 180 degrees with respect to the masonry platform 510. The two masonry platform anti-falling devices 531 are respectively arranged, so that the force applied to the masonry platform 510 is more uniform.
Example 3
Embodiment 3 is a modified structure of embodiment 2, and is different from embodiment 2 in that: as shown in fig. 4, the positioning grooves of the two braking plates 260 are arranged on the same cross section in a staggered manner. I.e., the brake plates 260 on either side of the support body 520 maintain a certain amount of relative height difference when arranged in elevation. This measure may improve the stopping distance for accidental downslide of the masonry platform 510; the accidental slide-down stopping distance is only half the distance between the detents on the brake plate 260 at the maximum.
The method comprises the following specific operation steps:
the method comprises the following three working states as shown in figures 8 and 9:
1. the masonry platform 510 is normally raised
When the masonry platform 510 is normally lifted, the ratchet mechanism of the ratchet component 533 continuously gives way in the clamping groove of the brake plate 260 and slides upwards; the interaction between the ratchet members 533 and the stop plates 260 does not form a stop for the raising movement of the masonry platform 510.
2. Accidental descent of the masonry platform 510
When the masonry platform 510 is accidentally lowered, the ratchet mechanism of the ratchet member 533 is inserted into the positioning groove of the brake plate 260 by the spring force of the spring 534, and the lower surface of the ratchet mechanism of the ratchet member 533 is in contact with the lower surface of the positioning groove of the brake plate 260. The falling force of the masonry platform assembly 590 formed by the combination of the masonry platform 510 and the support body 520 is transmitted to the tower body 220 through the brake plate 260, so that the stop is realized.
3. The masonry platform 510 descends under manual control
When the masonry platform 510 is in a high position and needs to descend, the masonry platform 510 can descend in an unlocking mode under the condition of manual control.
When unlocking is controlled manually, the unlocking pedal 538 is pedaled, downward force is applied to the unlocking sliding plate 535 through the traction rope, the unlocking sliding plate 535 rotates around the pin shaft 536 while the ratchet component 533 rotates around the floating pin shaft 537 to relatively rotate the ratchet component 533, under double compound motion, the ratchet mechanism of the ratchet component 533 retreats out of the positioning groove of the brake plate 260, one end of the unlocking sliding plate 535 abuts against two sides of the positioning groove of the brake plate 260, the ratchet component 533 is completely retreated out of the clamping groove of the brake plate 260 under the action of lever force, unlocking is achieved, and therefore descending of the masonry platform 510 is controlled manually.
