Description
Technical Field
[0001] The utility model belongs to the field of construction engineering, and more specifically, particularly relates to an insurance structure for an anti-falling hanging basket. Background Technique
[0002] As a suspension platform driven by a wire rope traction hoist to move up and down on the facade, the aerial work hanging basket is commonly used as a means of transportation for workers during high-altitude operations such as high-rise exterior wall painting, glass cleaning, and building construction. However, the inherent dangerous nature of high-altitude work makes the safety protection against the falling of the hanging basket the top priority to be considered before the operation.
[0003] Based on the above, safety nets are often used during high-rise building construction. If a worker accidentally falls during the operation, the safety net plays a certain buffering role for the falling worker. However, if a pendant is used as a moving tool, obviously the strength of the safety net is difficult to support, and it can no longer protect the personal safety of construction workers. Therefore, there are many hanging basket insurance structures on the market to prevent the hanging basket from falling. A good identification and determination structure can not only ensure that the safety rope is locked in time when the hanging basket falls, avoiding further falling; but also avoid self-locking when the hanging basket moves up and down normally, which brings inconvenience. At the same time, it is also necessary to consider that in the case of overloading of the hanging basket, the insurance device itself can withstand the strong impact caused by the falling. Now, an insurance structure for an anti-falling hanging basket is designed. Content of the Utility Model

When sliding, the sliding rod 18 is limited, so as to avoid the synchronous runner A being tilted by the pulling of the safety rope 30 and losing its due function, and the axis of the synchronous runner A always remains horizontal.
[0038] The specific usage mode and function of this embodiment:
[0039] In the present utility model, when in use, first lock the safety structure on the anti-falling steel pipe of the hanging basket through the locking structure A6 and the locking structure B7; then pass the safety rope 30 through the upper limit perforation 11 into the lock body 3, then pass through the gap between the two synchronous rotating wheels A17, pass through the limiting plate 13, and then pass through the gap between the pressing structure 22 and the synchronous rotating wheel 25, and finally pass out of the lock body 3 through the lower limit perforation 12; squeeze the limiting block of the guide rod B223 by the compression spring 224, cooperate with the synchronous rotating wheel B254, and push the pressing wheel 221 to press the safety rope 30 to enhance the biting force of the safety structure on the safety rope 30; when the hanging basket falls rapidly, the safety rope 30 is clamped between the two synchronous rotating wheels A17 and pulls the synchronous rotating wheel A17 upward, driving the lever 15 to rotate around the lever rotating shaft 14, and the barb on the left side of the lever 15 presses down on the pressure lever 29, causing the pressure lever 29 to rotate counterclockwise around the rotating shaft of the circular gear A26. The circular gear A26 meshes with the circular gear B27 and rotates in the opposite direction. The toothed bite 28 fixed on the right side of the circular gear B27 rotates counterclockwise around the rotating shaft of the circular gear B27, and the toothed bite 28 catches the outer ratchet 242, and the synchronous rotating wheel 25 is locked; when the hanging basket falls normally, the pawl 243 of the speed switch 24 rotates around the square shaft 245, and the buffer spring B247 abuts against the sliding groove 244 to keep the rotating shaft of the whole pawl 243 and the sliding groove 244 on the axis of the fixed shaft 23; when the hanging basket falls rapidly, the square shaft 245 rotates at an accelerated speed. Due to the centrifugal force, the pawl 243 and the sliding groove 244 gradually deviate to the side close to the pawl 243 during the rotation process until the pawl 243 contacts the inner ratchet 242 and the two engage. At this time, the synchronous rotating wheel 25 is stuck and stops rotating, the safety structure is locked at the height position fixed by the safety rope 30 and does not slide down, and the hanging basket is firmly fixed. This is the second layer of insurance for this safety structure.
