[0002] The billet lifting machine is an important equipment of the billet delivery system of the continuous casting machine, and is responsible for lifting the billet cut to size to the steel pushing carriage. The billet on the carriage is pushed to the hot charging position or the hot sending position by the steel pushing machine for transfer. The lifting machine is the key link of the billet transfer. The lifting machine has four position states of lifting in place, lifting in the middle, returning in the middle and in situ. The two most critical position states are lifting in place and in situ. At present, the steel wire rope is connected with the lifting machine mechanism, and the heavy hammer is driven by the steel wire rope to collect the lifting machine position signal. Because the steel wire rope is flexible, it is not hard connection, and there is a phenomenon that the steel wire rope is not tight, which leads to the failure to accurately collect the lifting machine position signal. At the same time, after long-term sliding wear, the steel wire rope will produce many burrs on the surface, causing the heavy hammer to be blocked, and the lifting machine position signal cannot be collected. In this case, the whole steel wire rope needs to be replaced, which is difficult to maintain and has a large workload.
