Abstract
The invention discloses an auxiliary support trolley for a high-speed railway wrecking crane and belongs to the field of auxiliary devices of a crane. The auxiliary support trolley comprises a load-bearing frame, a load-bearing crossbeam, a walking mechanism, a braking system, a hydraulic system and a dynamical system. Two sets of front wheels are respectively connected to two ends of a front frame longitudinal beam by bearings and two sets of rear wheels are respectively connected to two ends of a rear frame longitudinal beam by bearings. The front and rear frame longitudinal beams are matched and connected with the load-bearing crossbeam respectively by flexible connection mechanisms so that the load-bearing crossbeam and the load-bearing frame can rotate relatively and longitudinally move. The load-bearing crossbeam is hinged to a support oil cylinder of crane support legs by a spherical hinge support so that a large support counter-force on the crane support legs is transmitted to wheel sets of the load-bearing crossbeam and the load-bearing frame. Therefore, the auxiliary support trolley realizes that a support counter-force on the crane support legs is dispersed to the auxiliary support trolley, effectively solves the problem of a large crane concentrated load on a railway track, and realizes good operating performances of relative rotation and longitudinal movement between the crane support legs and the auxiliary support trolley.
