滑升模板的提升方式很多,模板的提升机具也有多种类型。如目前比较广泛使用的爬升式千斤顶,系借助于一种能交替进行锁固和放松的卡钳装置,沿一根细长的支承杆不断向上爬升,并自始至终地将荷载传递于支承杆。这样的卡钳装置,叫做卡具或者卡头。卡具在工作时,不仅要求能够传递荷载,而且要求动作灵活、可靠,既能保证锁固安全,又能在上升时,立即与支承杆脱
There are many ways to lift a sliding template, and there are many types of lifting devices for a template. For example, climbing jacks, which are more widely used at present, are steadily upwardly climbed along an elongated support rod by means of a caliper device that can be alternately locked and relaxed, and transfer the load to the support rod from beginning to end. Such a caliper device is called a clamp or a chuck. When the fixture is in operation, it not only requires that the load can be transferred, but also requires flexible and reliable operation. It can not only guarantee the safety of the lock, but also can immediately take off the support rod when it rises.
