根据《煤矿安全规程》(2006版)第403条规定:摩擦轮式矿井提升机的提升钢丝绳每两年更换一次。在更换提升绳的过程中,大多采用以旧绳带新绳的方法进行放绳,施工过程中存在一个新绳绳头与旧绳绳头连接的问题,新旧绳连接这个环节费时、费力,技术和质量要求高。新旧绳的接头方式多采用新旧钢丝绳搭接,用钢丝绳扎头卡制的连接方式。该方式的接头外形尺寸较大,钢丝绳扎头使用多,接头耗用时间长,经过天轮和滚筒时容易出绳槽,对天轮和滚筒衬垫有损伤。本文介绍的是一种新型的连接方式。1新旧钢丝绳的连接要求新旧绳连接处绕经提升机天轮和滚筒,旧绳带着新绳下放,绳头的连接必须满足如下要求:①外形尺寸必须满足顺利绕过提升机天轮和滚筒,而不致于受卡或跳出绳槽;②接头的承载能力达到全部钢丝绳悬垂长重量6倍以上的安全系数;③设备的体积小、重量轻,便于天轮平台处操作、放置;④施工方便,无须复杂的材料和工艺,操作简便,施工时间短;⑤接
According to “Coal Mine Safety Regulations” (2006 version) Article 403 provides: friction wheel mine hoist wire rope replacement every two years. In the process of replacing the hoisting ropes, most of the ropes use the old ropes with the new ropes to release the ropes. During the construction, there is a problem that the ropes of the new ropes are connected with the old ropes. The connection between the old and the new ropes takes time and laboriously, and the technical And high quality requirements. Old and new style of rope joints more use of new and old steel lap lap, with wire rope tie card system connections. The way the connector larger size, the use of wire rope tie much, the connector consumes a long time, after the days of the wheel and roller out of the rope slot easily, on the day wheel and cylinder liner damage. This article describes a new type of connection. 1 old and new rope connection requirements Old and new rope connection around the hoisting machine pulley and pulley, the old rope with a new rope down, rope connection must meet the following requirements: Dimensions must be sufficient to successfully bypass hoist days pulley and drum , But not by the card or jump out of the rope groove; ② joint carrying capacity of all rope overhang weight 6 times longer than the safety factor; ③ equipment, small size, light weight, easy to Tianzhu platform at the operation, placement; ④ easy construction , Without complicated materials and processes, easy to operate, short construction time; ⑤ access
