Description

Double-wire rope anti-falling high-altitude operation safety hanging bracket Technical Field The utility model relates to the technical field of safety hanging frames, in particular to a double-steel wire rope anti-falling high-altitude operation safety hanging frame. Background At present, in order to improve the safety of overhead operation, relevant safety production regulations and regulations are put forward in the country, and current safety hanging frame usually adopts a plurality of slings to connect, but in the safety hanging frame motion process, the hoist cable length that different reels were released has the error, leads to each hoist cable atress inconsistent, leads to hoist cable disconnection easily, has great potential safety hazard. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the double-wire rope anti-falling overhead operation safety hanging bracket which ensures the consistent length of slings at two sides through the rotation of the movable pulley, avoids unbalanced stress of slings, is simple, efficient, safe and reliable and is convenient to operate. The utility model provides a double-wire-rope anti-falling high-altitude operation safety hanging bracket, which comprises a bearing bracket, wherein a movable pulley with an axis extending along the horizontal direction is arranged on the bearing bracket in a rotating manner and is connected with the bearing bracket through an anti-falling mechanism, a sling is wound on the movable pulley, the two ends of the sling are respectively connected with a winding drum and a fixing frame, the length of the sling at the two sides is ensured to be consistent through the rotation of the movable pulley, the stress unbalance of the sling is avoided, after one end of the sling is disconnected, the bearing bracket moves downwards under the action of gravity, the movable pulley is driven by the sling to accelerate to rotate, the anti-falling mechanism is driven by the movable pulley to be started, the movable pulley stops rotating, and the sling continues to pull the bearing bracket to prevent the bearing bracket from falling. The anti-falling mechanism comprises a brake wheel coaxially and fixedly arranged on a movable pulley, a plurality of sliding grooves A extending along the radial direction of the brake wheel are formed in the brake wheel, a brake rod is arranged in the sliding grooves A in a sliding mode, the brake rod is connected with the brake wheel through a reset spring A, a cross rod is arranged on a bearing support and is intersected with the movement track of the brake rod, the brake wheel is driven to rotate in an accelerating mode through the acceleration rotation of the pulley, the brake rod moves outwards along the sliding grooves A under the action of centrifugal force and is intersected with the cross rod, and the movable pulley stops rotating.
