Abstract
The utility model discloses a transportation automobile support device capable of avoiding the damage of lateral force, in particular to a ground jack for a transportation automobile. The ground jack comprise a vehicle frame, a stand vertical to the vehicle frame and a support seat on the side face of the vehicle frame, the support device is arranged on the support seat, a support leg is movably arranged on the stand, and the support device can be adjustable and is movably connected with the end part of the support leg through a connecting frame. The utility model has the advantages of simple and stable structure and immunity to the influence of external force and greatly prolongs the service life of the ground jack for the transportation automobile.
Description
Technical field
The utility model discloses a kind of transport trolley bracing or strutting arrangement, especially transport trolley supporting leg of avoiding the side force infringement.
Background technology
Steel mill uses the transportation of slag ladle transport trolley to fill the slag ladle of slag, when the deslagging operation, the hydraulic ram of vehicle rear is propped, and all totally needs slag ladle is applied external force in slag ladle for making slag, be that vehicle frame bears certain external force, it is side force that this power passes to hydraulic ram.Because the hydraulic ram of transport trolley adopts hydraulic ram to support, hydraulic ram is easy to cause seal fails under the effect of side force, even cylinder block, piston rod damage.
Summary of the invention
The purpose of this utility model is to provide a kind of transport trolley supporting leg, is used for solving above-mentioned technology and adopts shortcomings such as hydraulic ram lost efficacy easily, damage under lateral forces.
The technical scheme that realizes the utility model purpose is as follows:
The transport trolley supporting leg, this supporting leg comprise vehicle frame, with the supporting seat of the vertically disposed support of vehicle frame, vehicle frame side, supporting seat is provided with bracing or strutting arrangement, is movably equipped with supporting leg on the support, bracing or strutting arrangement is adjustable bracing or strutting arrangement, and bracing or strutting arrangement and supporting leg end flexibly connect by link span.
Described bracing or strutting arrangement comprises gear cluster, leading screw, the leading screw seat of actuating device, pair of meshing, and the end that gear cluster is located at actuating device is connected with the leading screw seat, leading screw and leading screw seat screw thread fit, and the leading screw seat can rotate with gear cluster.
Described supporting leg comprises swash plate, transverse slat and supporting leg seat, and swash plate is movably connected on bracket end, and transverse slat is located at the swash plate end, and the supporting leg seat is located at the bottom surface of swash plate and transverse slat.
Adopted such scheme, when bracing or strutting arrangement supports supporting leg owing to be not to adopt hydraulic pressure to support, but adopted the leading screw support, energy firm stable under the effect of flank force, solved the problem of hydraulic ram seal failure, during the gear cluster of actuating device driving engagement, leading screw can upwards take in or expenditure downwards when the leading screw seat rotated, thereby drove the withdrawal that is supported in of supporting leg.
Useful benefit of the present utility model is a simple and stable structure, not influenced by external force, the very big service life that prolongs transport trolley with supporting leg.
