The utility model relates to a four roller type steel wire rope guiding mechanism, which is used to guide the steel wire rope when the rope out direction of the winch drum is consistent with the load lifting direction. The four rollers are respectively fixed in the four longitudinal grooves of the mounting frame by four pin shafts to form a rope passing hole; the baffle plate is fixed at the bottom of the mounting frame by screws, and the direction of the cross groove on the baffle plate is consistent with the direction of the four rollers; the upper part of the mounting frame is installed with bearing 1, and the lower part is installed with bearing 2. When in use, the guide mechanism is installed at a certain position in the rope out direction of the winch drum through the bearing, the end with the baffle is toward the load direction, and the wire rope passes through the rope passing hole. When the wire rope swings with the load greatly, the wire rope is clamped into the cross groove on the baffle to drive the guide mechanism to rotate as a whole. The utility model realizes to provide guidance for the steel wire rope without changing the direction of the steel wire rope, eliminates the interference of the load swing on the arrangement of the steel wire rope on the drum, and at the same time does not hinder the normal operation of the steel wire rope.

四滚轮式钢丝绳导向机构
本技术涉及各类绞车钢丝绳的导向结构
,具体是一种四滚轮式钢丝绳导向机构。
技术介绍
目前的各类绞车通常使用定滑轮实现钢丝绳的导向。要使定滑轮发挥导向作用,则钢丝绳必须在定滑轮上形成一定的包角,这样就势必改变钢丝绳的方向。在实际工作中,有许多绞车出绳方向与负载提升方向一致,需要在不改变钢丝绳方向的条件下进行钢丝绳的导向,而定滑轮不能满足使用要求。对于此类情形,许多场合都不使用导向机构,钢丝绳由绞车出绳后直接连接负载。譬如常用的行车、电葫芦等。在起重行程较短、使用环境良好、可靠性要求不高的情况下,以上设计能够满足使用要求。然而在长行程起吊、使用环境恶劣、可靠性要求很高时,被吊负载往往会有大幅度的摆动,安全隐患很大,且如果不使用钢丝绳导向机构,则负载的摆动会直接干扰钢丝绳在卷筒上的排布,特别是多层卷筒,很容易出现乱绳。
