The hoisting tool is divided into two symmetrical parts, each part is composed of a semi-annular bottom board (1), two hoisting boards (2), a semi-annular reinforcing ring (3) and several reinforcing board (4), where the bottom board (1) is provided with a plurality of fixing holes (11); the hoisting boards are arranged on two open ends of the bottom board eudipleurally, the inner ends of the hoisting boards are fixed with the two open ends of the bottom board respectively, the external ends extend outwards and freely, the inner ends of the hoisting boards (2) are provided with bolt joining holes (22), and the external ends of the hoisting boards (2) are provided with hoisting holes (21); the reinforcing ring (3) is arranged on the inner ring of the bottom board (1); and the reinforcing boards (4) are arranged on the bottom board (1) in a radiation shape. By means of the utility model, the hoisting operation of the exhaust valve cylinder lid assembly is simple, reliable and practical, it is possible to save time and reduce workload.
Description
(1) technical field
The utility model relates to the integral lifting instrument of blow off valve cylinder cap assembly when main frame is opened and inspect on a kind of medium-and-large-sized boats and ships.Belong to the shipbuilding technical field.
(2) background technology
At present, institute's medium-and-large-sized marine main engine power of building is between 10000KW～40000KW, and the weight of main exhaust valve barrel cap assembly is between 4～12 tons.Build up operation after regular meeting carries out some coherence checks or replacing spare part because of various problems need that main exhaust valve barrel lid etc. is hung main frame at boats and ships.Original way that adopts is to take blow off valve and cylinder cap apart independent lifting respectively, has increased the work capacity of many dismountings and multiple dress, also can spend a lot of times.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of does not need blow off valve and the cylinder cap integral lifting instrument of blow off valve cylinder cap assembly separately and when main frame is opened and inspect on the medium-and-large-sized boats and ships of integral lifting.
The purpose of this utility model is achieved in that the integral lifting instrument of blow off valve cylinder cap assembly when main frame is opened and inspect on a kind of medium-and-large-sized boats and ships, described lifting tool is divided into two parts symmetrical front and back, each part is formed by base plate, a boatswain chair, reinforcing pad and brace panel, described base plate is semi-annular shape, base plate is provided with a plurality of fixed orifices, be used for with need rise hanging piece be connected, fixing; Described boatswain chair has two, be symmetrically arranged in two open ends of base plate, captive joint with two open ends of base plate respectively in described two boatswain chair the inners, the outer end stretches out and freely stretches, this plays boatswain chair the inner and is provided with the Bolt Connection hole, be used for described two parts symmetrical front and back integral lifting instrument is connected, fixes, play a boatswain chair outer end and be provided with lifting eye, be used for lifting; Described reinforcing pad is semi-annular shape, and this reinforcing pad is arranged at the inner ring of described base plate; Described brace panel has polylith, is radial arrangement on base plate.Reinforcing pad and brace panel play integrally stiffened effect.
The beneficial effects of the utility model are:
Adopt the utility model lifting tool integral lifting main exhaust valve barrel cap assembly simple, reliable and practical, can save time and reduce work capacity.
(4) description of drawings
