Compared with the prior art, the utility model it is nimble, convenient to have the upset of hanging the piece, adjusts the load lifting capacity of two dollies or distributes the load ratio in a flexible way, can satisfy more lifting and hang job requirements, and main girder structure is simple, the atress good, and it is convenient to operate operation and routine maintenance, has reduced manufacturing and operation cost, improves the poor in coordination with operation and security performance of two dollies.
Description
Technical field
The utility model relates to shipbuilding gantry crane technical field, especially a kind of single-beam shipbuilding gantry crane.
Background technology
In recent years, along with the high speed development of domestic ship building industry, domestic shipyard generally have employed shipbuilding gantry crane and the span winch coordinative composition of equipments pattern in the operation of building berth Regional Synergetic, with the productivity effect of lifting means.Shipbuilding gantry crane is made up of portal-framed structure, upper dolly, lower dolly and operating unit, and upper dolly and lower trolley travelling, on girder, realize hoisting crane by two dolly collaborate and hang the lifting of loads, handling, lift and the standing up of aerial segmentation.The girder pattern of shipbuilding gantry crane is divided into twin-spar construction and single-spar construction, girder pattern is twin-spar construction, on it, dolly and lower dolly are cross-placed in the box beam in two same cross sections respectively, realize hoisting crane and hang the structural segmented demand of standing up of carrying aloft, because two coxostermum overall stress of box beam are less, and web weight accounts for about 50% of main beam structure deadweight, so the degree of utilization of material is not high.Girder pattern is the shipbuilding gantry crane of single-spar construction, on the upper box that on it, dolly and lower dolly are arranged at same box beam and lower box, make main beam structure structural form complicated, especially dolly is descended to be arranged in the bottom of girder, lower dolly application force is unfavorable to main beam structure, with dolly repair and maintenance is difficult at present.
The single-beam shipbuilding gantry crane of prior art is because only having single girder, lower dolly is difficult to realize realizing passing through upper dolly above girder, generally all be designed to lower dolly passing through to upper dolly below girder, this just requires that girder bottom must arrange the orbit of lower dolly, beam interface is divided into main box and both sides small box structure or beam interface is divided into upper and lower two main boxes and both sides small box structure by single girder, these two kinds of section forms of beam complex structures, manufacture degree of difficulty is large, structure stress is not good enough, stock utilization is low, manufacture and operation cost high, especially dolly repair and maintenance difficulty and poor safety performance is descended.
Utility model content
The purpose of this utility model is not enough for prior art and a kind of single-beam shipbuilding gantry crane of design, adopt collaborative the lifting of single girder double trolley structure, under the suspension hook of a wherein dolly, a revolution suspender is set, realize rotation and the upset of hanging piece, simplify the overall manufacturing process of hoisting crane, the inner space of especially single casing main beam structure is large, the electric control room of complete machine can be positioned over girder inside, operation operation and daily attention are conveniently, structure is simple, substantially improve the stressed of girder, stock utilization is high, alleviate hoisting crane deadweight, reduce manufacture and operation cost, simplified structure part manufacture and design difficulty, solve the problem of dolly maintenance difficult.
The purpose of this utility model is achieved in that a kind of single-beam shipbuilding gantry crane, comprise the portal-framed structure be made up of girder and rigid leg and flexible leg and the lifting trolley be arranged on girder, rigid leg and flexible leg have operating unit, portal-framed structure is walked on crane track by operating unit, be characterized in that girder is the casing list main beam structure of upside-down trapezoid, its top flange panel is arranged two lifting trolleys on same track, two lifting trolleys are walked on girder by track, track and girder are for being fixedly connected with, and lifting trolley is connected for rolling with track; Described lifting trolley has two suspension hooks, arranges revolution suspender under two suspension hooks of a wherein lifting trolley.
Described revolution suspender is made up of the bottom of irrotational top and rotation, and revolution suspender is fixedly connected with two suspension hooks by irrotational top.
The utility model compared with prior art has flexible overturning, the convenience of hanging piece, adjust load-carrying ability or the flexible allocation load ratio of two dollies, can meet and more lift job requirements, main beam structure is simple, stressed good, simplify the overall manufacturing process of hoisting crane, the inner space of especially single casing main beam structure is large, the electric control room of complete machine can be positioned over girder inside, operation operation and daily attention are conveniently, alleviate hoisting crane deadweight, reduce manufacture and operation cost, improve work compound's technique and the safety of two dollies.

Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cross section structure schematic diagram of Fig. 1;
Fig. 3 ~ Fig. 5 is the utility model concrete utilization schematic diagram.
Detailed description of the invention
Accompanying drawings 1, the portal-framed structure that the utility model is made up of girder 1 and rigid leg 7 and flexible leg 8 and the lifting trolley 2 be arranged on girder 1 form, rigid leg 7 and flexible leg 8 have operating unit 9, and portal-framed structure is walked on crane track 10 by operating unit 9.
Accompanying drawings 2, described girder 1 is the casing list main beam structure of upside-down trapezoid, and two lifting trolley 2, two lifting trolleys 2 its top flange panel arranged on same track 6 are walked on girder 1 by track 6, track 6 and girder 1 are for being fixedly connected with, and lifting trolley 2 is connected for rolling with track 6; Described lifting trolley 2 has two suspension hooks 3, and wherein two suspension hook of a lifting trolley 2 arranges revolution suspender 4 for 3 times; Described revolution suspender 4 is made up of the bottom of irrotational top and rotation, and revolution suspender 4 is fixedly connected with two suspension hooks 3 by irrotational top.
Accompanying drawings 3, when structural segmented 11 are lifted by two lifting trolleys 2, one end of structural segmented 11 is hung by the revolution suspender 4 of a lifting trolley 2 and carries, the other end of structural segmented 11 is hung by two suspension hooks 3 of another lifting trolley 2 and carries, and two lifting trolleys 2 lifting structural segmented 11 are walked according to job requirements or walked on crane track 10 by operating unit 9 on girder 1.
Accompanying drawings 4 ~ Fig. 5, when structural segmented 11 needs rotations or when standing up, two suspension hooks 3 of the other end of structural segmented 11 and another lifting trolley 2 are broken off relations and unloads, rotated structural segmented 11 or again link up with after standing up by revolution suspender 4 as required, the skyborne flexible upset of implementation structure segmentation 11, according to the technological requirement lifting operation, adjust load-carrying ability or the flexible allocation load ratio of two lifting trolleys 2, can meet and more lift job requirements.
More than just be further described the utility model, and be not used to limit this patent, all be the utility model equivalence enforcement, within the right that all should be contained in this patent.
