Problems solved by technology
In the process of hoisting operation, the amplitude of the jib of the crane is supported by the jib hinge seat. Since the jib hinge seat is fixed on the hull, the jib of the crane cannot be hoisted in multiple working positions; during towing During the operation, because the jib of the crane is in the cantilever state, the center of gravity of the whole ship is high, the ability of the jib to resist the lateral load generated by the roll of the hull is weak, and the anti-wind and wave performance is poor. Generally, it can only withstand the wave height below 5 meters. The operating range of the crane is limited due to the wind and wave conditions; in addition, because the overall design height of the jib of the crane is high, the existing crane is not convenient for maintenance of the jib

The invention relates to an arm support hinge seat system of a crane and an arm support type crane. The arm support hinge seat system is used for fixing an arm support of the crane arranged on a shipbody. The arm support hinge seat system comprises a sliding rail, an arm support hinge seat and multiple hinge seat fixing bases. The sliding rail is configured to be arranged on the ship body along the longitudinal direction of the ship body; the arm support hinge seat can move on the sliding rail; the multiple hinge seat fixing bases are configured to be arranged on the ship body, the multiple hinge seat fixing bases are arranged along the extending direction of the sliding rail, and the hinge seat fixing bases can be connected with the arm support hinge seat to fix the arm support hinge seat. According to the arm support type crane comprising the arm support hinge seat system, the arm support of the crane can carry out hoisting at multiple working positions, the arm support of the cranecan be placed on the ship body, and therefore the operation range of the crane is widened; and in addition, due to the fact that the arm support of the crane can be placed on the ship body, the arm support is convenient to maintain.
Description
Technical field [0001] The invention relates to the technical field of cranes, in particular to a boom hinged seat system of a crane and a boom crane. Background technique [0002] Floating cranes can be divided into rotary and non-rotating types according to their slewing performance. The non-rotating type is also known as the fixed boom type. The fixed boom floating crane has a lower cost and has a wide range of applications. However, the existing The fixed boom type floating crane installed on the hull of the hull has a boom hinge seat at the front end of the hull and is fixed on the deck or supporting frame foundation of the hull. In the process of hoisting operations, the boom of the crane is supported by the boom hinge base. Since the boom hinge base is fixed on the hull, the crane boom cannot be lifted in multiple working positions; During the operation, because the crane's boom is in a cantilever state, the center of gravity of the whole ship is high, and the boom has a ...
