Anti-tilting dual protection device of hanging basket

Abstract

The invention discloses an anti-tilting dual protection device of a hanging basket. The anti-tilting dual protection device of the hanging basket is provided with two sets of rope clamping mechanisms,and a safety rope and a working rope penetrate the rope clamping mechanisms correspondingly. A swing arm mechanism is in transmission connection with the two rope clamping mechanisms at the same time. When the anti-tilting dual protection device moves, the swing arm mechanism simultaneously triggers the two rope clamping mechanisms, and the two rope clamping mechanisms synchronously move to clampthe ropes penetrating the rope clamping mechanisms. During running, when protection of any one set of rope locking device loses efficacy, including that a safety lock loses efficacy or a steel wire rope is broken, the protection of the other set of rope locking device is still effective, and the anti-tilting reliability of the hanging basket is greatly improved. An arranged guide wheel and the swing arm mechanism are coaxial, constraint is formed on the horizontal shifting of the working rope, the tilting rotating center of a suspended platform coincides with the rotating center of the swingarm mechanism, and the effects of external factors on the rope locking angle of the safety lock are eliminated. The anti-tilting dual protection device of the hanging basket has the remarkable advantages of being high in rope locking precision, simple in structure, reliable in action and low in cost and is suitable for being widely applied in the double-hanging point hanging basket.

Description

technical field [0001] The invention relates to the field of safety protection for a hanging basket, in particular to a double protection device for a hanging basket working at a high place with double lifting points. Background technique [0002] At present, the high-altitude operation in the construction field widely uses the double-suspension-point high-altitude operation basket (abbreviated as the suspension basket), which is mainly composed of two sets of suspension mechanisms erected at high altitudes, a suspension platform for manned lifting operations, and two suspension platforms on the suspension platform. The hoists installed at the two hoisting points, the anti-tilt safety locks respectively installed upstream of the two hoists, and the corresponding wire ropes. Anti-tilt safety locks mainly include swing arm rope clip safety locks. The lock rope device mainly includes a swing arm mechanism and a rope clamp mechanism. The swing arm mechanism usually adopts an ope...

Problems solved by technology

It can be seen that the angle of the lock rope of the safety lock is not only related to the characteristics of the lock rope itself, but also related to the installation position of the safety lock and the hoist on the suspension platform. Since point N is far away from point P, the suspension platform is inclined When the working rope produces a large horizontal offset to the safety lock, coupled with the dispersion of the installation position, the technical defects of low precision and poor interchangeability of the lock rope of the prior art safety lock are caused. Although these are not fatal problems, However, it restricts the performance of the safety lock and increases the difficulty of maintenance.
