The invention relates to the technical field of pulley blocks, and particularly relates to the fields of overhead crossing, mountain rescue, fire fighting and emergency rescue, high-altitude operation, evacuation transfer, outdoor activities, cable sliding, military affairs and the like. A double-track sliding device comprises two device bodies, the two device bodies are symmetrically arranged, a plurality of fixed stainless steel rivets are installed between the side faces of the two device bodies in a penetrating mode, bearings are fixedly arranged on the surfaces of the fixed stainless steel rivets in a sleeving mode, and pulleys are fixedly arranged on the surfaces of the outer rings of the bearings in a sleeving mode. According to the scheme, the multiple pulleys are arranged, the rope can be connected with the pulleys at different positions to be used for establishing a pulley system for pulling in all directions, and the multiple pulleys rotate on the bearing after being stressed, so that the pulleys have good sliding efficiency and are used for reducing friction force between the rope and the pulleys; and therefore, a worker can conveniently pull the rope, the rope is particularly smooth, stable and smooth during overhead crossing, personnel conveying and rope slipping, and the convenience and the safety of operation are improved.

    本发明涉及滑轮组技术领域,尤其应用于架空横渡、山地救援、消防抢险、高空作业、疏散转移、户外活动、溜索、军事等领域。一种双轨道滑动装置,包括两个器身,两个所述器身对称排列,两个所述器身的侧面之间均贯穿安装有多个固定不锈钢铆钉,所述固定不锈钢铆钉的表面固定套设有轴承,多个所述轴承的外圈表面固定套设有滑轮。本方案中,通过设置多个滑轮,多个滑轮的设置,绳索可与不同位置的滑轮连接,用于建立在各个方位拉拽的滑轮系统,而且多个滑轮受力后均在轴承上旋转,使得滑轮具有很好的滑动效率,用于减少绳索和滑轮之间的摩擦力,进而方便工作人员拉拽绳索,在架空横渡、输送人员、溜索时,特别顺滑、平稳而流畅,提升了操作的便捷性和安全性。
