Abstract

The invention discloses a manned system of a ship crane. An independent manned winch is mounted on the rear portion of a cargo winch on a crane jib. The manned winch is composed of a wall frame, a winding drum, a manned lifting cage, a hydraulic motor, a speed reducer, a winding drum brake and a valve set. The winding drum is fixed to the jib through the wall frame. The speed reducer is arranged in the winding drum. The speed reducer is provided with a wet hydraulic normal close brake and is connected with the hydraulic motor. The valve set is mounted on the hydraulic motor. A manned steel wire rope is wound on the winding drum and is connected with the manned lifting cage through a lifting hook. The winding drum brake is mounted on the winding drum and is provided with a lifting hook ascending and descending limiting device. The requirements for safety and reliability of the manned winch of the manned system are higher than those of the cargo winch, the winding drum brake is additionally arranged on the basis of integrating the brake on the speed reducer, dual brake is formed, the two brakes are controlled by the same oil way and act at the same time, and the design redundancy rate of the safety and reliability of the manned winch is fully guaranteed.

Description

technical field [0001] The invention specifically relates to a manned system of a marine crane. Background technique [0002] Marine jib crane is a kind of mechanical equipment installed on ships for loading and unloading cargo between ships or between ships and wharves. Cargo, but in the special working conditions of some ship types, it is necessary to use jib cranes to complete the lifting work of personnel. According to the requirements of the crane manned regulations of relevant classification societies, ordinary cargo winches installed on marine cranes cannot be used for manned because of safety and reliability issues. If personnel transfer is required, special manned winches must be equipped. At present, with the development of the marine industry, more and more ships need to use ordinary cranes to complete the transfer of personnel. Therefore, we need to design a manned winch and control system that can be installed on a common crane to complete the work of lifting ...
