Description

Portable hanging base for hatch cover Technical Field The invention relates to the technical field of ship supporting equipment, in particular to a portable hanging base for a hatch cover. Background In some cabins of ships, equipment rooms, sailing cabins and the like, the upper deck is basically provided with a hatch cover, which is mainly used as a person escape opening, an access opening, a cargo access opening and the like. The ship hatch is the only vertical channel between the cabin and the deck, the fixed crane is difficult to accurately butt joint the hatch edge due to the limitation of the lifting angle, the portable crane is small in size, and the high-efficiency transfer of 'cabin-deck' materials can be realized by virtue of the advantage of flexible deployment. Existing portable hanging bases for hatch covers use tripod type or welded fixed bolt bases. The welded fixed bolt base is immovable, and the base is preset in advance at all possible positions to be used, so that material waste is caused, and limited precious space on a ship body is occupied when the portable crane is not installed. Disclosure of Invention In view of the above problems in the prior art, an embodiment of the present invention provides a portable hanging base for a hatch cover, so as to solve the technical problems of large occupied space, material waste and occupied ship space in the prior art. The embodiment of the invention provides a portable hanging base for a hatch cover, which comprises the following components: the supporting bottom plate is characterized in that one side plate body of the supporting bottom plate is attached to the top end of the hatch coaming, the other side plate body extends out of the edge of the hatch coaming in an overhanging manner, a hollowed-out first avoiding part is arranged at the part of the plate body corresponding to the hatch coaming inner hatch, and a bolt hole is formed in the position of the plate body corresponding to the hatch coaming fixing stud; The fixed cylinder is vertically fixed on the overhanging section plate body of the supporting bottom plate, and the top of the cylinder body of the fixed cylinder is opened; The bottom upright post of the portable crane is arranged in the fixed cylinder in a penetrating way and is fixedly connected with the fixed cylinder through the limiting component. In one embodiment, the spacing assembly comprises, The positioning pin penetrates through the fixed cylinder and the bottom upright post of the portable crane and is connected and fixed with the fixed cylinder and the bottom upright post of the portable crane; the limiting bolt is arranged on the fixed cylinder in a penetrating way, and the inner side end of the limiting bolt is propped against the bottom upright post of the portable crane so as to prevent the bottom upright post of the portable crane from shaking.
