Novel height-adjustable supporting leg of inner floating roof storage tank

Abstract

A novel height-adjustable supporting leg of an inner floating roof storage tank comprises a supporting leg body, a supporting top and a height adjusting part, the supporting leg body comprises a supporting leg outer pipe, a T-shaped lead screw and a supporting leg inner pipe, the T-shaped lead screw and the supporting leg outer pipe are sleeved with the supporting leg outer pipe body, and a T-shaped lead screw base and the bottom of the supporting leg outer pipe are fixed to an inner tank bottom plate of the storage tank; a height adjusting part is arranged on the T-shaped lead screw and comprises a nut which sleeves the T-shaped lead screw and is in threaded connection with the T-shaped lead screw, and the nut is connected with the bottom of the supporting leg inner pipe; the upper end of the supporting leg inner pipe extends out of the supporting leg outer pipe; a supporting top is arranged at the top end of the supporting leg inner pipe and comprises a supporting leg cap, a cap seat, a thrust bearing and a bearing seat; the cap seat is formed by connecting the top of a cap seat shaft with a horizontally arranged top tray; the cap seat shaft is connected into the bearing seat through the thrust bearing sleeved outside and is connected to the top of the supporting leg inner pipe; a supporting leg cap is supported on a top disc of the cap seat, a limiting sleeve is fixed to the bottom of the supporting leg cap and sleeved outside the top end of the supporting leg inner pipe, and a top bolt is connected with a horizontally-arranged nylon plate to be in contact support with the bottom face of the floating roof in the storage tank. The height of the supporting legs is adjustable, and water filling and discharging are not needed.

Description

technical field [0001] The invention relates to the technical field of storage tank floating roofs, in particular to a novel height-adjustable support leg of a storage tank with an inner floating roof. Background technique [0002] The inner floating roof storage tank is an oil tank with a floating roof above the liquid level in the vaulted oil tank, and its storage of light oil products can reduce losses by 95%-97% compared with the vaulted roof tank. For the internal floating roof storage tank, the floating plate in the oil storage tank is a floating top cover that floats on the liquid surface of the oil tank and rises and falls with the oil product, which can reduce the volatilization loss of the medium, and because the internal floating plate transfers the medium, that is, the inside of the tank The storage material is effectively isolated from the air, which also reduces the risk of fire and explosion to a certain extent. The vault outside the oil storage tank can preve...
