The invention relates to the technical field of net hauling winches, in particular to a net hauling winch and a cultivation work ship. The net hauling winch comprises a seat frame and a mounting base, and the seat frame is provided with a hook and a mounting hole. Locking holes extending in the vertical direction and a limiting sliding groove with an upward opening are formed in the mounting base, the hooks are slidably connected into the limiting sliding groove in a hung mode in the vertical direction, and the mounting holes are communicated with the corresponding locking holes and fixedly connected with the corresponding locking holes through fasteners. The breeding work ship comprises the net hauling winch, an installer can loosen the seat frame only by lifting the seat frame and enabling the hook to be slidably hung in the limiting sliding groove in the vertical direction, pre-assembly of the seat frame and the installation base in a hanging mode is achieved, the installer does not need to keep lifting motion for a long time, and the disassembly and assembly efficiency is improved. Due to the fact that the locking hole extends in the vertical direction, the matching performance of the locking hole and the mounting hole is improved. When the seat frame and the installation base are installed in a hanging mode, the fastener is directly replaced, the seat frame does not need to be lifted, and the replacement difficulty of the fastener is reduced.
本发明涉及起网绞车技术领域,尤其涉及一种起网绞车及养殖工船。起网绞车包括座架和安装底座,座架设置有挂钩和安装孔。安装底座上设置有沿竖直方向延伸的锁紧孔和开口朝上的限位滑槽,挂钩沿竖直方向滑动地挂接于限位滑槽内,安装孔与对应的锁紧孔连通并通过紧固件固定相连。养殖工船包括上述的起网绞车,安装人员仅需将座架抬起后使挂钩沿竖直方向滑动地挂接于限位滑槽内即可松开座架,实现了座架与安装底座挂接方式的预组装,无需安装人员长时间保持托举动作,提高了拆装效率。由于锁紧孔沿竖直方向延伸,提高了锁紧孔与安装孔的匹配性。在座架与安装底座保持挂接安装时直接更换紧固件,无需托举座架,降低了紧固件的更换难度。
