摘　　要：卷扬式启闭机在机架和相连接的工作桥桥面相应部位预留一定规格的孔洞,以便于闸门启闭时钢丝绳的通过和观察闸门的运行状况,采用固定式防尘挡板封闭在钢丝绳保养时需要人工挪开和封闭,工作劳动强度大且效率低,而且不便于现场运行人员观察闸门运行状况,存在一定的安全隐患。结合实际情况,开展卷扬式启闭机绳孔自动封闭系统研究,采用可移动天窗代替固定式防尘挡板,利用原来的封板支架安装活动式启闭器,并与闸门启闭控制电路有效连接,实现了在闸门运行时封闭装置的自动启闭,不但克服了上述困难,而且能够确保运行人员可以实时观察闸门运动以及水面的情况,更好地对装置进行控制以及根据水面的实际情况进行调节,同时提高了工作效率,为其他类似工程提供参考。A certain size of holes are reserved in the corresponding parts of the frame and the working bridge deck of the winch-hoist,so as to facilitate the passage of the wire rope and the observation of the operation status of the gate when the gate is opened and closed.The use of fixed dust-proof baffles requires manual removal and closing during wire rope maintenance,which is labor-intensive and low-efficiency,and it is not convenient for on-site operators to observe the operating status of the gate,which has certain safety hazards.Combined with the actual situation,the research on the automatic closing system of the rope hole of the winch-hoist is carried out.A movable skylight is used to replace the fixed dust-proof baffle,and the original sealing plate bracket is used to install the movable opening and closing device,which is effectively connected with the gate opening and closing control circuit.The automatic opening and closing of the closing device during the operation of the gate is realized,which not only overcomes the above difficulties,but also ensures that the operator can observe the movement of the gate and the situation of the water surface in real time,and better control the device and adjust according to the actual situation of the water surface.At the same time,it improves work efficiency and provides reference for other similar projects.
