when the climbing frame ascends, the stop lever 4 on the right side of the rotating shaft 3 is subjected to upward thrust given by the climbing frame from the lower part, the stop lever 4 drives the rotating shaft 3 to rotate anticlockwise, the stop lever 4 is in contact with the baffle plate 10 when rotating anticlockwise, but the baffle plate 10 can rotate clockwise around the hinge shaft under the action of the stop lever 4, so that the stop lever 4 is abducted, the stop lever 4 passes through the baffle plate 10 and then passes between the two transverse plates 8, and the stop lever rotates circularly continuously, so that when the climbing frame ascends, the sliding block 6 does not move, the rotating of the rotating shaft 3 is not hindered, and the climbing frame can normally climb;
when the climbing frame descends normally, the stop lever 4 on the right side of the rotating shaft 3 is pushed downwards by the climbing frame from above, the stop lever 4 drives the rotating shaft 3 to rotate clockwise, the stop lever 4 firstly passes through the two transverse plates 8 when rotating clockwise and then contacts with the baffle 10, the baffle 10 cannot rotate anticlockwise around the hinge shaft due to the torsion spring between the baffle 10 and the vertical plate 7, so that the stop lever 4 needs to push the sliding block 6 to move upwards after contacting with the baffle 10, the stop lever 4 is separated from the sliding block 6 after pushing the sliding block 6 to slide upwards to a certain height because the sliding track of the sliding block 6 is in the vertical direction and the stop lever 4 rotates around the axis of the rotating shaft 3, and the sliding block 6 is not at the highest point capable of sliding per se when the stop lever 4 is about to be separated from the sliding block 6, and the descending speed of the climbing frame is slow when the climbing frame descends normally, so that the sliding block 6 is slow when the stop lever 4 pushes the sliding block 6 to move upwards, therefore, the slide block 6 can slide downwards under the gravity once separated from the stop lever, so that the gear teeth at the right end of the cross bar cannot be meshed with the two gears 9 on the rotating shaft 3 in the process, the clockwise rotation of the rotating shaft 3 cannot be influenced, and the climbing frame can normally descend;
when the climbing frame falls, the stop lever 4 on the right side of the rotating shaft 3 is pushed downwards by the climbing frame from above, the stop lever 4 drives the rotating shaft 3 to rotate clockwise at a high speed, the stop lever 4 still passes through the two transverse plates 8 when rotating clockwise, then the baffle plate 10 is pushed to move upwards quickly, when the stop lever 4 pushes the slider 6 to move upwards to a certain height and is about to be separated from the slider 6, the height of the slider 6 still does not reach the highest point capable of sliding, but the slider 6 slides upwards due to the high speed of the upward sliding of the slider 6 at the moment, after the stop lever 4 is separated from the baffle plate 10, the slider 6 still slides upwards under inertia and finally slides to the highest point capable of sliding, so that the gear teeth at the right ends of the two transverse plates 8 are meshed with the gear 9 on the rotating shaft 3, the rotating shaft 3 is locked, the stop lever 4 cannot rotate continuously, the climbing frame cannot fall continuously, and the rightmost end of the transverse plate 8 is positioned on the left side of the axis of the rotating shaft 3, the gravity of the climbing frame can be converted into the right thrust of the gear 9 to the transverse plate 8 by the rotating shaft 3, so that the meshing between the gear teeth on the transverse plate 8 and the gear 9 is only tighter and tighter under the gravity of the climbing frame, even if the climbing frame shakes after stopping the falling, the locking state of the rotating shaft 3 cannot be relieved, and the safety is extremely high;
when the locking of the rotating shaft 3 needs to be relieved, the climbing frame only needs to climb upwards for a certain distance, the rotating shaft 3 rotates anticlockwise under the pushing of the climbing frame, then the gear teeth on the transverse plate 8 are reversely screwed out from the gear 9, then the sliding block 6 slides downwards under the gravity, the climbing frame is normally lowered, and the locking relieving of the rotating shaft 3 can be realized.
It is worth mentioning that, even if cement falls on the rotating shaft 3 when the device is used, the rotating shaft 3 is subjected to larger resistance when rotating, but the rotating shaft 3 in the device is always driven by the climbing frame, the rotating resistance of the rotating shaft 3 obviously cannot resist the driving force given to the rotating shaft 3 by the climbing frame, and the rotating shaft 3 does not rotate or rebound, so that the cement falling on the rotating shaft 3 cannot affect the use of the device.
The utility model has the following remarkable advantages:
1. when the climbing frame is used, the stop lever 4 can be pushed to rotate by the climbing frame which moves up and down, the speed of the stop lever 4 for pushing the sliding block 6 to slide upwards is different through the difference between the normal descending speed and the falling speed of the climbing frame, once the stop lever 4 is separated from the sliding block 6 when the climbing frame descends normally, the sliding block 6 moves downwards under the gravity, the gear teeth on the right side of the transverse plate 8 are not driven to be meshed with the gear 9, and the sliding block 6 can continue to slide upwards under the inertia even if the stop lever 4 is separated from the sliding block 6 when the climbing frame falls, so that the gear teeth on the right side of the transverse plate 8 are meshed with the gear 9, the rotating shaft 3 is locked, the climbing frame is prevented from falling, the structure is novel, and the reliability is high.
2. When the device locks the rotating shaft 3, the rightmost end of the transverse plate 8 is positioned on the left side of the axis of the rotating shaft 3, so that the impact of the creeper in falling can only enable the gear teeth on the transverse plate 8 to be meshed with the gear 9 more tightly, the locking mechanism cannot be loosened even if the subsequent creeper shakes, part of acting force applied to the rotating shaft 3 is converted into leftward extrusion force on the transverse plate 8, and the compression coefficient of the transverse plate 8 is obviously greater than the shear coefficient, so that the device can bear larger load.
3 when the utility model is used, even if cement falls on the rotating shaft 3, the rotating shaft 3 is subjected to larger resistance when rotating, but the rotating shaft 3 in the device is always driven by the climbing frame, the rotating resistance of the rotating shaft 3 obviously cannot resist the driving force given to the rotating shaft 3 by the climbing frame, and the rotating shaft 3 does not rotate or rebound, so that the cement falls on the rotating shaft 3 and cannot influence the use of the device.
