Abstract

The utility model discloses a support pillar bracket for a ball-shaped storage tank. On the support pillar, a support pillar bracket is fixedly connected. The support pillar bracket is fixedly connected with the lower part of the connecting surface of the support pillar and a ball-shaped storage tank. The support pillar bracket is provided with an arc contact surface matched with the ball-shaped storage tank. The arc contact surface of the support pillar bracket is fixedly connected on the outer wall of the shell of the ball-shaped storage tank. The support pillar is provided with an arc contact surface matched with the ball-shaped storage tank. The utility model with simple structure compensates for the defects that a narrow gap is difficultly welded at the lower part of the connecting place, the weld quality is imperfect, the restraint intensity of the position of the ball shell is high, etc. The utility model which has simple manufacture and easy installation improves the stress concentration problem in the position of the ball shell, with the stress decreased above 30% maximally.

Description

The spherical storage tank support supporting plate
Technical field
The utility model relates to a kind of pillar supporting plate of spherical storage tank.
Background technique
At present the pillar of the spherical storage tank of using be generally directly with the following portion connecting structure pattern of spherical shell joint be connected, the flange connection, its welding position is narrow and small, welding is difficult, welding quality is unreliable, cause that easily this position stress of spherical shell concentrates and crack, cause the safe operation coefficient of spherical storage tank to reduce.
Summary of the invention
The purpose of this utility model provides a kind of concentrated spherical storage tank support supporting plate of terminal stress that spherical shell is connected with pillar that improves.
For achieving the above object, solution of the present utility model is: a kind of spherical storage tank support supporting plate, be fixedly connected with a pillar supporting plate on the described pillar, described pillar supporting plate is fixedly connected on the bottom of pillar and spherical storage tank junction surface, described pillar supporting plate is provided with the arc contact surface suitable with spherical storage tank, the arc contact surface of described pillar supporting plate is fixedly connected on the housing outer wall of spherical storage tank, and described pillar is provided with the arc contact surface suitable with spherical storage tank.
The utility model is simple in structure, it can remedy the narrow defectives such as welding, bad, this position restraint intensity height of spherical shell of weldquality that are difficult to of joint underclearance, make simple and easy, easy for installation, save steel about 10%, reduce cost more than 15%, improve the problem of stress concentration at this position of spherical shell, maximum can reduce stress more than 30%.By finite element analysis computation, the stress minimum through the result relatively draws this position of spherical shell of U-shaped support board structure connection is about 180～240MPa.
Description of drawings
Fig. 1 the utility model embodiment is welded on the structural representation on the spherical tank.
Fig. 2 the utility model embodiment's plan view.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the plan view of Fig. 2.
Embodiment
As shown in Figures 1 to 4, be welded with a pillar supporting plate 3 on its described pillar 2 of spherical storage tank support supporting plate described in the utility model, described pillar supporting plate 3 is welded on the bottom of pillar 2 and spherical storage tank 1 junction surface, described pillar supporting plate 3 is provided with the arc contact surface suitable with spherical storage tank 1, and the arc contact surface of described pillar supporting plate 3 is welded on the shell wall of spherical storage tank 1.This pillar supporting plate 3 is that steel plate is rolled into U-shaped, is cut to the bottom from the top of this U-shaped pillar supporting plate 3, and cutting surface is the arc shaped surface that matches with the outer wall camber line of spherical storage tank.Described pillar 2 also is provided with the arc contact surface suitable with spherical storage tank 1.
