Abstract

The invention discloses a lifting semitrailer outrigger, comprising an outer leg, lifting inner leg sheathed inside the outer leg, and a screw connecting the outer leg with the lifting inner leg, wherein a folding support leg is connected at the lower end of the lifting inner leg, and a wheel structure is arranged at the lower end of the folding support leg; the screw is respectively connected with a guide screw fixed at the inner side of the lifting inner leg and a bearing block fixed at the inner side of the outer leg; fixed nuts are connected at the top end of the screw and the upper end of the bearing block, a plane pressure bearing is connected at the lower end of the bearing block, and the inner side of the plane pressure bearing is connected with the screw; the outer leg is equipped with a screw rod, and a spiral bearing is connected inside the outer leg and the back end of the screw rod; and the outer side of the spiral bearing is clamped with the outer sides of the tops of the fixed nuts. The lifting semitrailer outrigger has the advantages of compact structure, low cost, small welding deformation, convenient manufacture and assembly, high precision, great lifting force, portability and flexibility, foldable folding support leg and convenient operation. And high- strength mill ball-resistant nodular iron nuts are used.

Description

technical field [0001] The invention relates to a semi-trailer outrigger, in particular to an elevating semi-trailer outrigger. Belongs to the automotive field. Background technique [0002] At present, the advantages of semi-trailers in medium and long-distance logistics transportation are becoming more and more obvious, and they have become the most important type of transportation vehicles. The outer sides of the left and right side beams at the front end of the semi-trailer are usually equipped with movable outriggers to help support the semi-trailer when loading and unloading goods or parking for maintenance, and the height of the semi-trailer can be adjusted according to the actual height of the traction seat of various tractors. These movable outriggers should generally be retracted during the driving of the semi-trailer, so as to reliably prevent the movable outriggers from contacting the ground and prevent safety accidents from being induced. [0003] The outrigge...
