Description

Technical Field

[0001] The utility model relates to the technical field of heavy machinery equipment, in particular to a European-style hoist transformed into a large-distance double-hanging-point synchronous lifting mechanism. Background Art

[0002] The crane uses an electrophoretic magnet sling to lift a steel plate to a cutting machine or to lift waste; since the steel plate has a certain length and width. Because the steel plate is relatively long, the sling is suitable for double lifting points to adapt to its working conditions, so the lifting mechanism of the crane must have two lifting points to connect the sling; to ensure the stability and safety of the lifting, the two lifting points are required to rise and fall synchronously. The usual practice is to use two sets of lifting mechanisms for types with larger lifting point spacing, but the synchronization of lifting and lowering cannot require too high precision. For this type of rated lifting weight is not large (the thickest steel plate does not exceed 2 tons), the lifting point spacing is large, and the two lifting points require higher synchronization. Therefore, a technician in this field provides a European hoist transformed into a large-distance double-lifting-point synchronous lifting mechanism to solve the problems raised in the above background technology. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a European hoist transformed into a large-distance double-hanging-point synchronous lifting mechanism, including a lifting seat, a wire rope hoist is fixedly installed on the left side of the lifting seat, a drum is installed in the wire rope hoist, a double-hanging-point sling is arranged directly below the lifting seat, a sling seat is symmetrically fixedly installed on the upper end of the double-hanging-point sling, a lower pulley group is fixedly installed on the sling seat, a plurality of guide wheels are fixedly installed on the lower end of the lifting seat, and upper pulleys are symmetrically installed on the left and right centers of the inner part of the lifting seat.

[0004] Preferably, the wire rope hoist is a double-drum hoist, and the drum has double wire ropes to ensure that the hook can be lifted and lowered vertically without deviation.

[0005] Preferably: the guide wheel on the left side needs to adjust the deflection angle between the wire rope and the drum and the pulley, so as to ensure the stability of vertical lifting.

[0006] Preferably, the vehicle frame is symmetrically fixedly mounted on the left and right ends of the lifting mount.

[0007] Preferably: two steel wire ropes are wound on the drum, one of which is a normal rope that is lowered and fixed to the left frame after passing through the lower pulley group on the left side fixedly installed on the sling hanging seat and the upper pulley on the left side; the other rope is unloaded from the drum, passes through the guide wheel below, changes direction to the guide wheel on the right side, and then passes through the lower pulley group on the right side fixedly installed on the sling hanging seat and the upper pulley on the right side and is fixed to the right frame.

[0008] Preferably, the lower pulley assembly is a front-to-rear symmetrical pulley assembly.

[0009] Technical effects and advantages of the utility model:

[0010] 1. When the utility model is used, by driving a single drum on the wire rope hoist, the double-hanging-point sling wound on the wire rope can be driven by the guide wheel to change the position of the hanging point in the process of winding the wire rope through the lower pulley group and the upper pulley. The single hanging point is changed into a double hanging point by the rope winding method, which meets the requirement of synchronous lifting of the two hanging points and reduces the cost compared with the conventional two sets of lifting mechanisms.

[0011] 2. When the utility model is used, the wire rope hoist uses a double-drum hoist to ensure that the hook is lifted and lowered vertically without deviation, and at the same time, the lifting height of the hoist needs to meet the lifting height requirements after modification, which increases practicality.
