Embodiment

[0024] Example: such as Figure 1 to Figure 4 As shown, a squirrel-cage steel pipe connection device includes a first connection seat 1 for installation in the rear end of the previous steel pipe 3 and a second connection seat 2 for installation in the front end of the rear steel pipe 4, wherein the first The second connecting base 2 can rotate relative to the first connecting base 1 .

[0025] Such as figure 1 and figure 2 As shown, the first connecting seat 1 includes a connecting sleeve 14, a first contact bracket 12 for clamping on the inner wall of the previous steel pipe, and a first fixing frame 11 for abutting against the rear end of the previous steel pipe. The first fixing frame 11 is fixed on the connecting sleeve 14 . It also includes a first movable frame 13 and an adjusting screw 15, the first contact bracket 12 is connected between the first fixed frame 11 and the first movable frame 13, and one end thereof is welded on the first fixed frame 11, The other e...

Abstract

The invention relates to a mouse cage type steel pipe connection device. The mouse cage type steel pipe connection device comprises a first connection base and a second connection base; the first connection base at least comprises a connection sleeve, a first contact support and a first fixed frame; the first fixed frame is fixedly connected to the connection sleeve; the second connection base atleast comprises a second fixed frame, a second contact support and a second movable frame; the two ends of the second contact support are connected to the second fixed frame and the second movable frame correspondingly; and by means of a rotating speed difference of front and rear steel pipes, the second connection base and the first connection base can relatively rotate, so that the second movable frame can move in the axial direction of the connection sleeve relative to the second fixed frame, and the second contact support can expand or shrink in the peripheral direction. The mouse cage type steel pipe connection device is wide in application range, and can achieve connection of the steel pipes in different specifications; and automatic connection and separation of the front and rear steel pipes is achieved, the production efficiency is improved, the labor intensity is relieved, the labor time is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of steel pipe connection, in particular to a squirrel-cage steel pipe connection device. Background technique [0002] During the 3PE / FBE external anti-corrosion process of the steel pipe, the rubber wheels arranged obliquely on the conveying line make the steel pipe rotate and move forward at the same time. The rubber wheels not only play the role of transmission, but also play the role of supporting the steel pipe. The 3PE / FBE external anti-corrosion implementation stage includes intermediate frequency heating, FBE spraying, and PE winding. Due to the requirements of construction material properties and technology, there are no contact support points within this section, and the length of this section is about 3.5 meters. When the length of the steel pipe is greater than 8 meters, it can pass through this range without any impact on production. When the length of the steel pipe is less than 8 meters, due ...
