[0025] As attached Figures 1-5 As shown, the locking mechanism includes a fixed plate 6 fixedly connected to the top of the steel plate 1. A telescopic assembly 7 is fixedly connected to the inner wall of the fixed plate 6. A movable plate 8 is fixedly connected to one end of the telescopic assembly 7. A limiting block 801, inserted into the outer wall of the anti-impact connecting column 3, is provided at one end of the movable plate 8. A limiting groove 302 for inserting the limiting block 801 is provided on the outer wall of the anti-impact connecting column 3. The vertical cross-sectional length and width of the limiting groove 302 are greater than the vertical cross-sectional length and width of the limiting block 801, respectively. A T-shaped slider 802 connected to the top of the steel plate 1 is provided at the bottom of the movable plate 8. A T-shaped groove 102 is provided horizontally on the top of the steel plate 1 corresponding to the outer side of the T-shaped slider 802. The telescopic assembly 7 includes components fixedly connected to the outer wall of the fixed plate 6. A fixed cylinder 701 is provided, with a telescopic rod 702 connected horizontally to the inner side of its end. The end of the telescopic rod 702 is fixedly connected to the outer wall of the movable plate 8, and the other end of the telescopic rod 702 extends into the interior of the fixed cylinder 701 and is fixedly connected to a connecting plate 703.

[0027] Working principle: This utility model designs an intelligent construction hoist anti-overrun safety device, the specific structure of which is shown in the attached instruction manual. Figures 1-5As shown, in this technical solution, the anti-collision safety device is fixedly installed on the top crossbeam of the construction hoist drive scaffold. The detachable anti-collision connecting column 3 can be assembled and disassembled with the steel plate 1. During assembly, pushing the movable plate 8 outward causes the telescopic assembly to retract. At this time, the T-shaped locking block 5 at the bottom of the anti-collision connecting column 3 is embedded into the T-shaped locking groove 101 at the top of the steel plate 1, ensuring a stable and precise connection of the anti-collision connecting column 3 to the top of the steel plate 1. Then, the movable plate 8 is released, the telescopic assembly 7 resets, pushing the movable plate 8 towards the anti-collision connecting column 3, and causing the limiting locking block 801 on the movable plate 8 to engage. The anti-collision connecting column 3 is locked in the limiting slot 302 on the outer wall. At this time, the anti-collision connecting column 3 maintains a stable state after being connected to the steel plate 1. Then, the anti-collision connecting column 3 is tightened and fixed to the outer frame of the hoist drive by the locking bolt 4. Alternatively, it can be reinforced by fixing the fixing plate 2 with screws. The anti-collision connecting column 3 contacts and limits the limit component at the top of the guide rail frame as the hoist drive frame rises, thus preventing the intelligent construction hoist cage from rushing out of the guide rail frame. The detachable anti-collision connecting column 3 can be easily replaced when it deforms after a period of use.
