Description

Auxiliary supporting structure for supporting leg of hoisting equipment Technical Field The utility model relates to the technical field of cantilever lifting equipment, in particular to an auxiliary supporting structure of a supporting leg of lifting equipment. Background The cantilever crane is widely applied to the scenes of site loading and unloading, warehouse hoisting, ship shore operation and the like due to special structural form and strong operation flexibility, the existing cantilever crane supporting leg structure mostly adopts a rigid supporting rod to directly support the ground, and the ground is pressed by the ground friction and gravity to hoist the reaction force, so that the ground is always uneven, soft and the like in actual operation, the single supporting structure is difficult to provide enough transverse supporting and stabilizing force, and particularly when the single cantilever crane supporting arm swings greatly or lifts in heavy load, the potential hazards of torque deviation or sideslip are more easily generated. Based on the supporting leg auxiliary supporting structure, the utility model designs a supporting leg auxiliary supporting structure of the lifting equipment so as to solve the problems. Disclosure of Invention The utility model aims to provide an auxiliary supporting structure for supporting legs of hoisting equipment so as to solve the technical problems. The auxiliary supporting structure for the supporting leg of the lifting equipment comprises a supporting leg rod and a cross beam arm, wherein the outer wall of the supporting leg rod is fixedly connected with two symmetrical limiting plates, a swivel is rotatably arranged between the two limiting plates, the outer wall of the swivel is fixedly connected with two symmetrical connecting columns, one end of each connecting column is fixedly connected with a joint, one end of each joint is provided with a hanging hole, a self-locking hook is hung in each hanging hole, one end of each self-locking hook is fixedly connected with a steel rope, and the other end of each steel rope is fixedly connected with a first seat plate; The utility model discloses a landing leg pole, including landing leg pole, first bedplate, second bedplate, landing leg pole one end fixedly connected with second bedplate, fixedly connected with side stay between second bedplate and the landing leg pole, stake nail hole has all been seted up to second bedplate and first bedplate outer wall. Preferably, a baffle is fixed on the outer wall of the connecting column, and the baffle is arranged on the outer side of the connecting position of the connecting column and the joint and used for limiting the sliding of the steel rope. Preferably, the steel rope is led out by the self-locking hook, winds around the connecting column between the baffle and the swivel, and extends outwards to be fixedly connected with the first seat board, so that the length of the use requirement can be adjusted. Preferably, the swivel is sleeved on the supporting leg rod between the two limiting plates, and the swivel can rotate around the supporting leg rod in the axial direction. Preferably, one end of the beam arm is rotatably connected to one end of the leg bar, which is far away from the first seat plate, in a hinged manner, and is used for being connected with the crane body to provide a transverse path and support. Compared with the prior art, the utility model has the beneficial effects that: Two strands of steel ropes are simultaneously connected with the first seat board and the swivel, after the first seat board is fixed, flexible compensation of lateral tension of the supporting leg rod is realized, after the second seat board is fixed, the potential hazards of torque deviation or sideslip are not easy to generate in supporting stability force lifting, and the steel ropes can be wound around the connecting column to adjust the service length, and through the rotatable fit of the swivel, more supporting angles and operation sites can be suitable for.
