In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further explained below with reference to the accompanying drawings.
In this embodiment, referring to fig. 1 to 4, the present invention provides the following technical solutions: the device for reducing the deflection of the steel pipe comprises a pipe clamp assembly 1, a right-angle reinforcing assembly 2 and a groove type reinforcing assembly 3, wherein the pipe clamp assembly 1 comprises a pipe hoop 11, a bolt and a nut 12. The pipe hoop 11 can be made of steel plate or purchased with finished double-hole short pipe clamps. The right-angle strengthening component 2 comprises two right-angle strengthening ribs which can be made of steel plates or can be purchased with finished angle steel. The groove type strengthening component 3 comprises two groove type reinforcing ribs, can be manufactured by steel plates and can also purchase finished channel steel.
The right-angle reinforcing component 2 and the groove-shaped reinforcing component 3 are selected according to the following principles: when the nominal diameter of the steel pipe is DN50-DN150, a right-angle strengthening component 2 is selected; and when the nominal diameter of the steel pipe is DN150-DN300, the groove type strengthening component 3 is selected. When the nominal diameter of the steel pipe is larger than DN300, the device is not suitable to be adopted.
The wall thickness d of the pipe clamp 11, the right-angle reinforcing component 2 and the channel-shaped reinforcing component 3 is determined according to the following principle: when the wall thickness of the pipeline is less than or equal to 4mm, d = the wall thickness of the pipeline; when the pipe wall thickness is > 4mm, d = (pipe wall thickness/2+1) mm.
