Description

The split crane span structure of bridge crane six
Technical field
The utility model belongs to hoisting machinery technical field, and in particular to a kind of split portal structure of bridge crane six.
Background technology
Bridge crane is that crossbearer carries out the crane gear of material handling in workshop, factory building, warehouse and stock ground overhead.It is Several parts such as dolly, traveling mechanism of the larger traveller and control cabinl pulpit by crane span structure, equipped with hoisting mechanism are constituted.
The current split crane span structure structural shape of conventional bridge crane six, is that girder and end carriage are whole by being welded into one Body, crane span structure is an inseparable frame structure.This structure mainly has a disadvantage that:
(1) structure bulky, bulky, transport inconvenience;
(2) installation difficulty is big, and installation accuracy is not high;
(3) anti-fatigue ability is poor.Attachment weld at connection between girder and carriage is be easiest to occur fatigue rupture one Position.Therefore, this Anti-Fatigue ability is unsatisfactory;
(4) big generally existing " three legs " phenomenon of crane span structure rigidity, wheel load skewness, wheel service life is short.
Utility model content
Problem to be solved in the utility model is to provide that a kind of simple in construction, easy for installation, anti-fatigue ability is strong, improve car Take turns the Overhead Crane Bridge of service life.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that:The split crane span structure of bridge crane six, Quadro frame structure including two girders and two groups of end carriage component compositions;
The end carriage component includes two butt beams and a tie-beam, and the end carriage includes connection end and fixing end, described Connection end is provided with connecting portion, and the connecting portion of the two ends of the tie-beam respectively with the two butts beam is hinged;
The two ends of the girder are overlapped on the end carriage of described two groups of end carriage components the same side and fixed thereto respectively;
The bottom surface of the fixing end of the end carriage is fixed with lifting machine trolley group;
The lifting machine trolley group has at least 4 groups wheels for being distributed in the crane span structure corner, the lifting machine trolley group Traffic direction it is identical with the length direction of the end carriage.
The height of the end carriage cross section is less than the width of its cross section.
The girder is connected with the end carriage by flange.
The girder is vertical with the end carriage.
The connecting portion is the connecting plate that the connection end extends to side.
After adopting the above technical scheme, compared with traditional Overhead Crane Bridge, crane span structure can split into individual components, Portable construction is succinct, is easy to manufacture processing, transport, installs;Girder is ridden on end carriage, is connected with end carriage by high-strength bolt, peace Fill precision high, during bridge crane load-carrying, the shearing of end of main beam is mainly born by girder mother metal, shear resistance is strong, resist tired Labor ability is strong;" flat " structure that the end carriage depth of section of crane span structure is less than width has certain vertical flexibility, owns bridge machine Wheel contacts track, allows wheel load to be evenly distributed, and improves wheel service life.
Brief description of the drawings

Fig. 2 is the side view of the split crane span structure of the utility model bridge crane six
Fig. 3 is the structural representation of end of main beam
Embodiment
As depicted in figs. 1 and 2, the split crane span structure of bridge crane six, including two girders 1 and two groups of end carriage components composition Quadro frame structure;The end carriage component includes two butt beams 2 and a tie-beam 3.That is, with traditional overhead traveling crane The overall structure of machine crane span structure is compared, and the Overhead Crane Bridge includes the detachable butt beam 2 of two girders 1 and four, is it " six splits " structure.
The end carriage includes connection end 21 and fixing end 22, and the connection end 21 is provided with connecting portion, the tie-beam Connecting portion of the two ends respectively with the two butts beam is hinged;It is same that the two ends of the girder are overlapped on two groups of end carriage components respectively It is on the end carriage of side and fixed thereto;The girder is vertical with the end carriage.
(" cart runs machine i.e. alleged by background section with lifting machine trolley group for the bottom surface of the fixing end of the end carriage Structure ") it is fixed, the traffic direction of the lifting machine trolley group is identical with the length direction of the end carriage.
The height of end carriage cross section is less than the width of its cross section, and the vertical stiffness of end carriage is small, holds in the presence of load Easily occurring a small amount of vertical deformations, i.e. end carriage has certain vertical flexibility.Meanwhile, the height of end carriage cross section is transversal less than its The width in face, the horizontal rigidity of end carriage is sufficiently large, can avoid end carriage that excessive deformation occurs in the horizontal direction, turn into crane span structure Parallelogram and gnaw rail phenomenon.
The wheel count of lifting machine trolley group is usually 4 groups, and every group of wheel includes at least two wheel.The wheel of bridge machine is put In orbit, 3 points determine a plane, due to engineering in practice, mismachining tolerance absolute being, so as to cause 4 groups of wheels can not In one plane, the situation that wheel soars is certainly existed.The split crane span structure of the utility model bridge crane six is in handling weight During thing, girder 1 transmits the force to end carriage 2 after load is born, because end carriage has certain flexibility, so that can be in vertical side 3mm~5mm deformation is produced upwards, and then the wheel of the lifting machine trolley group under the bottom surface of the fixing end of end carriage 2 will all connect Rail-engaging road so that wheel load is distributed on all wheels, so as to effectively overcome cart " three legs " phenomenon, improves wheel and uses the longevity Life.
Fig. 3 show the end of girder, and the lapping ends of girder are connected on end carriage and by flange.
The connecting portion is the connecting plate 23 that the connection end extends to side.The end of tie-beam is hinged with connecting plate, So that whole tie-beam is located at the top of end carriage, it is easy to the installation and removal of tie-beam.
Track is laid above two girders, is easy to OTC's trolley (i.e. " dolly " alleged by background section) OK Walk.
The utility model has the advantage of:Simple for structure, girder, end carriage, tie-beam are separable individual components, both just It is readily transported again in lifting, storage;Easily manufactured, assembly precision is high;Anti-fatigue ability is strong;Simple installation is quick, time saving and energy saving; End carriage has certain vertical flexibility, makes all wheel contact tracks of bridge machine, allows wheel load to be evenly distributed, improve wheel service life.
