The utility model discloses further set up to: the winch is connected between the two mounting blocks in a rotating mode, a first gear is fixedly connected with one end of the winch in a coaxial mode, the mounting blocks extend out of the winch, a second gear is fixedly connected with the same shaft, the first gear is meshed with the second gear, a blocking cover is further arranged on the shaft, and the blocking cover is arranged on the first gear and the second gear in a covering mode.
Through adopting above-mentioned technical scheme, keep off the cover and can prevent that the locking rope from twineing on the gear to influence the transmission between capstan winch and the pivot, improve the life of gear.
To sum up, the utility model discloses following beneficial effect has:
firstly, the cage can be prevented from suddenly dropping due to faults, potential safety hazards to surrounding workers can be avoided, and the operation safety is improved;
secondly, the locking piece has simple structure, simple and convenient assembly process and low manufacturing cost;
thirdly, the locking effect of the locking piece is good.
