Abstract
The utility model discloses a fixed connection structure between a bridge crane and a movable steel frame foundation. The fixed connection structure is characterized in that two ends of a bridge frame of the bridge crane are respectively provided with a plate-type hinged support seat and a basin-type rubber support seat; and the plate-type hinged support seat and the basin-type rubber support seat are fixedly arranged on the movable steel frame foundation. Compared with the prior art, the fixed connection structure between the bridge crane and the movable steel frame foundation has the advantages of being high in loading capacity, flexible in plane rotation and large in horizontal displacement, the phenomena of deflection and rail gnawing of the movable steel structure foundation can be avoided, and the whole stability of the steel structure foundation is enhanced; and the fixed connection structure is simple in structure and convenient to maintain.
Description
Technical field
The utility model relates to the heavy lift technical field, and is especially a kind of for the crane in bridge type of dock and dock wharf and the fixed connection structure of removable Foundation of steel frame.
Background technology
Hinged-support is the fixing critical component that is connected with removable steel structure base of crane in bridge type, crane in bridge type is because various loads such as deadweight, lift heavy, trolley travelling and wind, can occur in the crane span structure plane displacement and around with the rotation of point of connection, therefore when the design crane span structure is connected with the basis, must consider that deflection is on the impact on basis, design discharges displacement, and reducing hoisting crane is vital to the adverse effect of steel structure base.
At present, crane in bridge type is connected with steel structure base, generally all adopts to rigidly connect and hinged combined supporting form, and namely an end of crane bridge is for being rigidly connected, and the other end of crane bridge is that the forms such as board-like hinge, ball-type hinge or flexible hinge are hinged.The form that these are hinged, can discharge well crane span structure around rotation or the swing of anchoring point, but in-plane displancement can't discharge, can only overcome by rigidly connecting a little, causing to rigidly connect holds steel structure to be subjected to load towards a side oscillation, this is very disadvantageous for steel structure base, also is the major reason that causes removable steel structure base to produce deflection and gnaw rail.
The utility model content
The purpose of this utility model is a kind of crane in bridge type of designing for the deficiencies in the prior art and the fixed connection structure of removable Foundation of steel frame, adopt the hinged-support combination support form of different structure at the crane span structure two ends, hoisting crane crane span structure produces when operation rotation, swing and horizontal displacement have been solved preferably, it is large to have load-carrying capacity, Plane Rotation is flexible, the advantage that horizontal displacement is large, and also simple in structure, cost is low, and installation and maintenance is convenient.
The purpose of this utility model is achieved in that the fixed connection structure of a kind of crane in bridge type and removable Foundation of steel frame, comprise crane in bridge type and removable Foundation of steel frame, the crane span structure two ends that are characterized in crane in bridge type are respectively equipped with board-like hinged-support and pot rubber bearing, described board-like hinged-support and pot rubber bearing are arranged on the removable Foundation of steel frame, and board-like hinged-support and pot rubber bearing and Overhead Crane Bridge and removable Foundation of steel frame are for captiveing joint.
Described board-like hinged-support is to arrange in pairs.
Described pot rubber bearing is to arrange in pairs.
It is large that the utility model compared with prior art has a load-carrying capacity, Plane Rotation is flexible, the advantage that horizontal displacement is large, hoisting crane crane span structure produces when operation rotation, swing and horizontal displacement have been solved preferably, avoid the deflection of removable steel structure base and gnawed the rail phenomenon, greatly improved the resistance to overturning of steel structure base, simple in structure, cost is low, and installation and maintenance is all very convenient.

The specific embodiment
Consult accompanying drawing 1, the utility model is comprised of crane in bridge type 3 and removable Foundation of steel frame 4, the crane span structure two ends of crane in bridge type 3 are respectively equipped with a pair of board-like hinged-support 1 and a pair of pot rubber bearing 2, described board-like hinged-support 1 and pot rubber bearing 2 are arranged on the removable Foundation of steel frame 4, and board-like hinged-support 1 and pot rubber bearing 2 and crane in bridge type 3 crane span structures and removable Foundation of steel frame 4 are for captiveing joint.
Consult accompanying drawing 6, the utility model is when hook load or trolley travelling, the in the vertical direction downwarp of the portal structure of crane in bridge type 3, produce an a pivot angle and along the b displacement of crane span structure length direction, this moment, board-like hinged-support 1 was by the rotation of board-like hinge around axle, the a angle of dissolving portal structure changes, and 2 of the pot rubber bearings of the crane span structure other end pass through horizontal displacement simultaneously, dissolve the b displacement along the crane span structure length direction.In addition because pot rubber bearing 2 has the swing ability of certain radian in the horizontal surface direction, swing for the portal structure horizontal direction that produces such as wind load, can dissolve equally, thereby can not produce adverse influence to removable Foundation of steel frame 4, preferably resolve the problem that removable Foundation of steel frame 4 is gnawed rail and sideslip.
