Description
Technical field
The utility model relates to the elevator machinery field, relates in particular to a kind of later-model single hinge with Z-shaped Shock-absorption track joint.
Background technology
In the hoisting crane that has the small rail car operation, trolley travelling is being installed on the track of crossbeam.Because crossbeam has luffing or other situation needs, crossbeam is divided into forward and backward big girder construction two parts, and is connected by the crossbeam hinge.Therefore the trolley travelling track also need disconnect at big girder construction position of articulating point place in front and back, is divided into forward and backward two parts track, and the zone of orbital docking is called rail joint.Performance when the shape of rail joint and structure can influence dolly through this zone, how to make dolly be reduced to minimum through vibrations and the impact that rail joint makes, two tracks can not interfered in crossbeam luffing process mutually before and after guaranteeing simultaneously, are two major issues that the rail joint design needs solution.
Before and after big girder construction hinge be divided into two kinds of two hinges and single hinges.In the structure of single hinge form, the pitching hinge is positioned at rail joint below, when track during with the crossbeam pitching, the path of motion of preceding track can and the back Orbital Overlap, cause interference problem.Therefore the rail joint of single hinge at first will be avoided the mutual interference of forward and backward track in the luffing process.
Trolley track is open circuited in the joint, the effect of rail joint be make dolly can pulsation-free from an orbital motion to an other track.Therefore in the structure of rail joint, enough wheel load switch transition zones should be arranged, make the dolly can smooth transition.
In present single hinge structure, interfere mutually for fear of forward and backward track, the trolley track joint of single hinge form all adopts the form of cutting sth. askew, and track is parallel to each other in the joint.Such rail joint can be avoided interference problem, but owing to do not have the wheel load transitional region in the position of orbital docking, the dolly wheel be directly from back track " jumping " to the preceding track, impact big when therefore having brought wheel through joint, the trolley travelling traveling comfort is poor, noise is big, causes serial problems such as trolley track and structure crack easily.
