Supporting device used for supporting oil cylinder

Abstract

The invention discloses a supporting device used for supporting an oil cylinder, comprising a supporting seat and a supporting shaft. One end of the supporting shaft is connected with the supporting seat which is used for supporting the oil cylinder. The supporting seat and the supporting shaft are in sliding fit by two self-lubricating devices which are arranged at two ends of the supporting seat respectively. Each self-lubricating device comprises an upper sliding ring, a lower sliding ring and a self-lubricating shaft sleeve which is arranged between the upper sliding ring and the lower sliding ring. The upper sliding ring is connected with the supporting seat and the lower sliding ring is connected with the supporting shaft. A limit stop which is used for preventing the supporting shaft from sliding out of the supporting seat is arranged at the side (close to the supporting seat) of each self-lubricating device. The supporting device provided by the invention not only has good supporting function, but also has the advantages of simpleness in manufacturing and long service life. The supporting device provided by the invention can effectively resolve the problem of hydraulic deflection of small-tonnage radial gates with large-opening surface holes. On the premise that stroke of the oil cylinder is unchanged, the installation size of the oil cylinder is reduced and the safety of the hydrocylinder is improved. In addition, the cost is low and the business prospect is good.

Description

technical field [0001] The invention relates to a component of a surface hole arc door hydraulic hoist, in particular to a supporting device for supporting a hydraulic hoist oil cylinder. Background technique [0002] The support of the existing surface hole arc door hydraulic hoist oil cylinder is to be connected at the end of the oil cylinder. However, such a support form has the following disadvantages: on the one hand, the oil cylinder itself is allowed to have a certain deflection due to its own weight, and after using this support form, it is necessary to increase the installation size of the oil cylinder, thereby increasing the slenderness ratio of the oil cylinder . During the use of the oil cylinder, due to the excessive installation size, the deflection of the oil cylinder increases, and the piston rod is prone to fatigue deformation, resulting in the failure of the normal use of the oil cylinder. On the other hand, due to the excessive deflection of the piston r...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the excessive deflection of the piston rod in the traditional supporting device, oil leakage and scratches of the piston rod are caused during the use of the oil cylinder, and increasing the diameter of the piston rod and the cylinder body is not conducive to the cost. The problem of control, the present invention provides a new type of supporting device for supporting the oil cylinder, changing the position of the supporting oil cylinder to solve the above problems
