Circular pipe inner wall support frame

Abstract

The invention discloses a circular pipe material internal wall supporting frame which is provided with a shaft (6) which is sleeved by a shaft sleeve (1) which is movably connected with a plurality of supporting rods (2) which are uniformly arranged on the circumference of the shaft sleeve (1); a spring (3) is arranged between the shaft sleeve (1) and the supporting rods (2); the external end of the supporting rod (2) is provided with an idler wheel (5); a plurality of idler wheels (5) are also distributed on the same circumference. The circular pipe material internal wall supporting frame is arranged deep inside the pipe material to carry out the supporting, the supporting effect is good, the phenomena such as collapse deformation, etc. are avoided, the coaxiality of the pipe material can be excellently ensured; furthermore, the spring is arranged between the supporting rods and the shaft sleeve, and the opening degree of the supporting rods can be automatically adjusted so as to be applicable to the pipe material of different pipe diameters and lead the idler wheels to closely contact with the pipe material.

Description

Technical field: [0001] The invention relates to a support frame, which is especially suitable for circular pipes. Background technique: [0002] As we all know, long circular pipes are not easy to support, and pipes with thinner walls are prone to collapse and deformation during brushing or processing, especially pipes with softer materials. Therefore, it is relatively difficult to clean or process the inner wall of the circular pipe, and the operation is time-consuming and laborious. And there is no device that can effectively support the inner wall of the circular pipe at present. Invention content: [0003] The present invention aims at the above-mentioned deficiencies of the prior art, and provides a simple in structure, convenient and practical support frame for the inner wall of a circular pipe. [0004] The technical solution of the present invention is: a support frame for the inner wall of a circular pipe, provided with a shaft 6, the shaft 6 is covered with a ...
