Sleeve type supporting leg structure of slag pot car

Abstract

The invention provides a sleeve type supporting leg structure of a slag pot car. The supporting leg structure is connected to the lower portion of a rear car frame and is composed of a supporting leg outer sleeve, a supporting leg inner sleeve and a supporting leg oil cylinder; the supporting leg inner sleeve is sleeved with the supporting leg outer sleeve, a cylinder barrel of the supporting leg oil cylinder is hinged to the supporting leg outer sleeve, a piston rod of the supporting leg oil cylinder is hinged to the supporting leg inner sleeve, and when the supporting leg oil cylinder extends, the supporting leg inner sleeve is drive to stretch out; in the whole motion process, the piston rod is hidden in the supporting leg inner sleeve, a wear-resisting plate is hidden in the supporting leg outer sleeve, the wear-resisting plate and the rod of the supporting leg oil cylinder are not exposed, reliability can be improved, and the structure is more durable; a square sleeve structure is adopted in the supporting leg structure, only one directional freedom degree exits, and supporting is more stable; the supporting leg structure is arranged on a supporting lower portion of a work large arm, the occupied space, in the width direction, of a rear car is small, the overhauling space of rear wheels can be increased, and maintaining convenience is improved.

Description

technical field [0001] The invention relates to a slag tank truck; [0002] In particular, it relates to a sleeve type outrigger structure of a slag tank truck. Background technique [0003] The slag tank truck is a mechanical product developed for the logistics transportation of hot slag in the slag discharge system of the metallurgical engineering production line. [0004] Slag tanker products are gradually used in the non-ferrous metallurgy industry. Due to the acidic environment of non-ferrous smelting, when the existing slag tanker outrigger cylinders are in use, their cylinder rods are exposed in the air, which is easy to be splashed with copper slag and acid gas corrosion, and the frequency of damage higher. [0005] In the slag tank truck in the prior art, when the outrigger cylinder is extended, the cylinder rod will be exposed. In addition, due to the limitation of space, other shielding cannot be added, and the external environment has a great influence on the p...

Problems solved by technology

[0004] Slag tanker products are gradually used in the non-ferrous metallurgy industry. Due to the acidic environment of non-ferrous smelting, when the existing slag tanker outrigger cylinders are in use, their cylinder rods are exposed in the air, which is easy to be splashed with copper slag and acid gas corrosion, and the frequency of damage higher

[0005] In the slag tank truck in the prior art, when the outrigger cylinder is stretched out, the cylinder rod will be exposed. In addition, due to the limitation of space, it is impossible to increase other shelters. When the slag tank is dumped, the external environment has a great influence on the piston rod.
