Technical field
The utility model relates to a kind of for the telescopic crane peculiar to vessel on the mini engineering ship.
Background technology
Entered since the new century, particularly in recent years, under the vigorously supporting of national policy, the shipbuilding industry of China had had significant progress, and marine technology also has a great development.In the construction of many water projects of country, all kinds of auxiliary vessels are had very large demand, especially in the inland river or the demand of the mini engineering ship that uses of harbour more and more.Such auxiliary vessel, tonnage is generally little, be generally less than 1000t, type length, molded breadth and the moldeed depth of ship are all smaller, type length is generally less than 50m, and molded breadth is generally less than 20m, and moldeed depth is generally less than 10m, and the hoisting crane of equipment aboard ship but often has the hoisting operation operating mode of large swinging radius, big elevating height.Be subject to space, stability and the boats and ships current problem on the inland river of boats and ships, the conventional deck crane of a large brachium can not be installed again on the ship, this moment, the deck crane of multi-expansion arm became optimal selection.Telescopic crane peculiar to vessel of import, prices are rather stiff.At present, China seldom has company can set foot in this field, domestic manufacturer in the sector, also only be to share the low-end product that advanced country has abandoned substantially, aim at international industry development direction, immediately following upper advanced foreign technology step, develop the product of international most advanced level, be the most urgent task of China's ship building industry.
The manufacturing of telescopic crane peculiar to vessel, the general deck crane of comparing is on technical risk, on the manufacturing process, higher to the integrated technology requirement, be not only the technical requirements to a company, also be simultaneously the requirement to a national relevant industries technology.
Summary of the invention
The purpose of this utility model is in order to solve an above difficult problem, develop a kind of multi-expansion deck crane that is applicable on the mini engineering ship, the utlity model has novel structure, compactness, external form succinct, take less between deck space, can realize the advantage such as many special engineered operations.
The purpose of this utility model is achieved through the following technical solutions: a kind of telescopic crane peculiar to vessel, comprise base, base is connected with body of the tower by rotary system, the engine installation of rotary system below being arranged on ship deck links to each other, principal arm is installed above the body of the tower, be inserted with the first telescopic boom in the principal arm, be inserted with the second telescopic boom in the first telescopic boom, the front end of principal arm is provided with the first telescopic system for control the first telescopic boom, be provided with in the second telescopic boom be used to the second telescopic system of controlling described the second telescopic boom, the coupling end of principal arm is provided be used to the main hoisting system of controlling main suspension hook, be provided with changing-breadth system between the below of principal arm and the rotary system, the below of principal arm is provided be used to the secondary hoisting system of controlling secondary suspension hook.
Further improvement of the utility model is: base inside is equipped with a cover hydraumatic swivel joint and a cover centre collector ring, and hydraumatic swivel joint and centre collector ring are controlled required electrical energy transfer to system liquid force feed and system to each actuating unit of hoisting crane.
The utility model compared with prior art has the following advantages: the utility model is by the design of multi-expansion arm, in the narrow and small between deck space of mini engineering ship, a deck crane that has large swinging radius, big elevating height is provided on this project ship, have novel structure, compactness, external form succinct, take less between deck space, can realize the advantage such as many special engineered operations.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-base, 2-body of the tower, 3-principal arm, 4 first telescopic booms, 5-the second telescopic boom, 6-rotary system, 7-master's hoisting system, the secondary hoisting system of 8-, 9-changing-breadth system, 10-the first telescopic system, 11-the second telescopic system, 12-engine installation, 13-master's suspension hook, the secondary suspension hook of 14-.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Fig. 1 shows the utility model telescopic crane peculiar to vessel, comprise base 1, base 1 inside is equipped with a cover hydraumatic swivel joint and a cover centre collector ring, hydraumatic swivel joint and centre collector ring are controlled required electrical energy transfer to system liquid force feed and system to each actuating unit of hoisting crane, base 1 is connected with body of the tower 2 by rotary system 6, the engine installation 12 of rotary system 6 below being arranged on ship deck links to each other, principal arm 3 is installed above the body of the tower 2, be inserted with the first telescopic boom 4 in the principal arm 3, be inserted with the second telescopic boom 5 in the first telescopic boom 4, the front end of principal arm 3 is provided with the first telescopic system 10 for control the first telescopic boom 4, be provided with the second telescopic system 11 for control the second telescopic boom 5 in the second telescopic boom 5, the coupling end of principal arm 3 is provided be used to the main hoisting system 7 of controlling main suspension hook 13, be provided with changing-breadth system 9, principal arm between the below of principal arm 3 and the rotary system 6, the luffing of the first telescopic boom and the second telescopic boom is all realized by changing-breadth system; Main actuating unit that is the hydraulic ram of changing-breadth system and telescopic system the inside all adopt mesohigh hydraulic ram peculiar to vessel, and be stable and reliable for performance; The below of principal arm 3 is provided be used to the secondary hoisting system 8 of controlling secondary suspension hook 14.
The utility model is considered space and the stability problem of mini engineering ship, the deadweight of hoisting crane must alleviate as far as possible, the center of gravity of hoisting crane must move down as far as possible, therefore the main components of hoisting crane is all made of the high-strength deck of boat, and the engine installation of hoisting crane independently is placed in the cabin below the ship deck, by the hydraumatic swivel joint and the centre collector ring that are installed in the hoisting crane base interior system liquid force feed and system are controlled required electrical energy transfer to each actuating unit of hoisting crane.Hoisting crane is provided with three joint arms, is respectively principal arm, the first telescopic boom, the second telescopic boom, and the expanding-contracting action of telescopic boom is realized by the ship hydraulic oil cylinder of large stroke.Hoisting crane is provided with two load hooks, and main suspension hook is used for the operation that hoists of little swinging radius, heavy load, and secondary suspension hook is used for the operation that hoists of large swinging radius, big elevating height, little load.During hoisting crane work, by stretching of telescopic boom, can realize the engineer operation of large swinging radius, big elevating height; When the hoisting crane shutdown, when shelving, the retraction owing to telescopic boom can realize again taking less between deck space, thereby has solved the problem of mini engineering ship narrow space.
