Steel wire rope adjusting device

Abstract

The invention discloses a steel wire rope adjusting device. The device comprises a support, a steel wire rope pressing plate, a sliding chute, a positioning plate, an adjusting nut, an adjusting screw, a guide rod, a steel wire rope fixing bolt pair, a positioning bolt pair and a nut fixing bolt pair. When the steel wire rope adjusting device is assembled, the lower plane of the support is fixedly arranged on an installation plane, the ends of steel wire ropes pass through the middle parts of the support and the steel wire rope pressing plate, the steel wire rope fixing bolt pair is tightened, the steel wire rope pressing plate is put in the middle of the support, the positioning plate is put in and the positioning bolt pair is tightened. When the steel wire ropes need to be adjusted, the tightened positioning bolt pair is loosened and the positioning plate is taken away, and the operation end of the adjusting screw is clamped by utilizing special tools, such as a wrench, to be rotated, so that the adjusting nut, the steel wire rope pressing plate and the steel wire ropes can move toward the needed adjustment directions together. The problem of height difference or inclination, caused by inconsistence of the length of the steel wire ropes due to various reasons, such as machining deviation and installation deviation of a drum and characteristic deviation of the steel wire ropes, of a lifting appliance can be solved by adopting the steel wire rope adjusting device.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a wire rope adjusting device suitable for various general and special hoisting gate or bridge cranes. Background technique [0002] At present, in order to ensure the balance of the spreader of various hoisting gantry or bridge cranes, when the hoisting mechanism adopts a wire rope, a balance pulley device is used in the wire rope winding system; for example, the publication number is 202542765U, and the publication date is November 2012 The Chinese patent document on March 21 discloses a wire rope pulley assembly, including a first pulley block, a second pulley block, and steel wire ropes worn on the first pulley block and the second pulley block, and the steel wire ropes pass through the first pulley block at intervals. Each pulley of the first pulley block and the second pulley block has its starting end and end located on the same side of the pulley shaft. The wir...
