The invention provides a steel wire rope lay length control device. With the device, the problem that in the prior art, because the lay lengths of steel wire ropes are not checked before a hoisting device takes up the ropes, the internal stress of the steel wire ropes become large or smaller, and the service life of the steel wire ropes is seriously influenced is solved. The device comprises a shell, wherein a roller is arranged in the shell, a hollow cylinder is arranged on the right side of the roller, the end, arranged on the outer side of the shell, of the hollow cylinder is sleeved with rotating cylinder, the rotating cylinder can drive steel wire ropes to twist, and a movable plate is arranged on the front side of the shell; a first bevel gear is arranged on the front side of the movable plate, a rotating shaft is arranged on the front side of the movable plate, a second bevel gear is arranged at the upper end of the rotating shaft, a first friction wheel is fixed to the lower end of the rotating shaft, a worm is arranged at the lower end of the movable plate, a worm wheel used in cooperation with the worm is arranged on the rotating cylinder, a second friction wheel is fixedto the front segment of the worm, the sections of the peripheral surfaces of the first friction wheel and the second friction wheel are of circular arc shapes, a third friction wheel is arranged between the first friction wheel and the second friction wheel, and the first friction wheel can drive the third friction wheel to rotate through the second friction wheel.

    本发明提供了一种钢丝绳捻距控制装置,有效的解决了现有技术中起吊装置在收绳前没有对钢丝绳的捻距进行校核,造成钢丝绳内部应力变大或者变小,严重影响钢丝绳寿命的问题;其解决的技术方案是,包括壳体,壳体内有滚轮,滚轮右侧有空心筒,空心筒置于壳体外侧的一端上套装有转筒,转筒能带动钢丝绳扭转,壳体前侧有活动板;活动板前侧有第一锥齿轮,活动板前侧有转轴,转轴上端有第二锥齿轮,转轴下端固定有第一摩擦轮,活动板下端有蜗杆,转筒上有与蜗杆配合的蜗轮,蜗杆前段固定有第二摩擦轮,第一摩擦轮与第二摩擦轮的外缘面的截面呈圆弧形,第一摩擦轮与第二摩擦轮之间有第三摩擦轮,第一摩擦轮经第二摩擦轮能带动第三摩擦轮转动。
