The invention discloses a movable thrust roller. A rubber roller is in a thrust or movable state by adjusting the position of heavy iron on a roller vertical rod; by adjusting the end portions of a steel wire inhaul cable head in clamping iron, an air extracting rod is in a fixed or loosened state, so that inflator piers can be closed or started. When the roller system is used on a site, the movable thrust roller only needs to be moved to a designated position, strong and stable thrust can be provided for the roller system through the thrust roller, adjustable connecting rods and the inflatorpiers. When the system needs to be moved, operation is convenient, and wide applicability is achieved. With the movable thrust roller system adopted, the technical problems of low thrust, instabilityand inconvenience in operation are solved. The mechanism is suitable for various construction sites.
本发明涉公开了一种可移动式止推型滚轮,通过调整重铁在滚轮立杆上的位置,使橡胶滚轮处于止推或可移动状态。通过调节卡铁中的钢丝拉索头端部,使抽气杆处于固定或放松状态,进而关闭或启动气筒墩。在现场只需要将可移动式止推型滚轮移动到指定位置后,可以通过止推型滚轮、可调联接杆、气筒墩为该滚轮系统提供较强、较稳定的止推力。需要移动时,操作也比较方便,具有广泛的适用性。解决了止推力不强、不稳定,操作不便的技术问题,适用于各种施工场地。
