Description

Steel wire rope anti-swing structure of electric hoist

Technical Field

The utility model relates to an auxiliary hoisting equipment, specific theory has related to an electric block's wire rope anti-swing structure.

Background

The crane refers to a multi-action hoisting machine for vertically lifting and horizontally carrying heavy objects within a certain range, which is also called a crown block, a gantry crane and a crane, and generally comprises a rack, a trolley, an electric hoist, a lifting appliance, a cart running mechanism and the like, wherein the trolley running mechanism drives a winch to move, a steel wire rope of the winch is connected with a lifting hook, the lifting hook is used for lifting goods, and because the steel wire rope is flexible, during normal work, inertia force generated by the large/small trolley of the crane in starting, stopping, accelerating, decelerating or turning motion can cause the lifting hook of the bridge crane and the swinging of the lifted weight, especially the large/small trolley of the crane in emergency can cause the steel wire rope to drive the lifted equipment or goods to swing, and great potential safety hazards are caused.

In order to solve the above problems, people are always seeking an ideal technical solution.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-2, a wire rope anti-swing structure of an electric hoist includes a first pulley block and a second pulley block fixed on a spreader 2 and perpendicular to each other, a cross beam 7 disposed corresponding to the first pulley block, a longitudinal beam 8 disposed corresponding to the second pulley block, a first anti-swing wire rope 6 wound around the first pulley block, a second anti-swing wire rope 12 wound around the second pulley block, and a wire rope lifting mechanism; specifically, a lifting mechanism may be provided for the first anti-swing wire rope and the second anti-swing wire rope, respectively, and the lifting mechanism may be an electric block that is mounted on the crane frame 1 and that operates synchronously.

Specifically, the first pulley block comprises a first movable pulley 4 fixed at the top of the lifting appliance 2 and first fixed pulleys 10 respectively arranged at two ends of the cross beam 7, and the first movable pulley 4 and the first fixed pulleys 10 form an inverted triangle structure; the second pulley block comprises a second movable pulley 3 arranged above the first movable pulley 4 and second fixed pulleys 11 respectively arranged at two ends of the longitudinal beam 8, and the second movable pulley 3 and the second fixed pulleys 11 form an inverted triangle structure; the central shaft of the first movable pulley 4 is connected with the central shaft of the second movable pulley 3 through a connecting rod 5.

In the hoisting process, the first anti-swing steel wire rope is wound on the first pulley block, the second anti-swing steel wire rope is wound on the second pulley block to form two V-shaped structures which are crossed with each other, the cross beam and the longitudinal beam are combined, the stability of the structure is fully improved, the large-amplitude swing is avoided, meanwhile, the cross beam and the longitudinal beam can also play a role in preventing the top of a crane from impacting a trolley mechanism when the crane arrives at the top.

Further, the fixed point of the first anti-swing steel wire rope 6 is fixed on the cross beam 7, and the fixed point of the second anti-swing steel wire rope 12 is fixed on the longitudinal beam 8.

Specifically, the connecting rod 5 is an L type connecting rod.
