s4, after the expansion to a proper degree, stopping rotating the tightening knob 203, and realizing the tight fixation between the threaded rod 202 and the central threaded hole on the connecting seat 201 through the thread matching between the two;
s5, after the expansion operation is completed, the tightening knob 203 is rotated in the reverse direction to take out the device body from the hose.
According to the invention, the inner core rod 301 is driven to move axially along the core rod body 1 by tightening or loosening the steel wire rope ring through a rope traction driving mode by virtue of the driving mechanism 2 arranged on one side, so that the supporting mechanism 4 is unfolded, meanwhile, the second roller 406 arranged at the top end of the roller rod 404 on the second supporting rod 402 is also contacted with the inner wall of the supporting shell 5, so that the contact area between the supporting shell 5 and the supporting structure is increased, the structural stability and the flexibility of the supporting mechanism 4 in folding and unfolding are ensured, and when the supporting shell 5 is fully contacted with the soft foam plastic paved on the inner wall of the hose, the effect of fixed support can be achieved. It should be noted that, when the driving mechanism 2 is used, the threaded rod 202 with the wire rope loop should be previously screwed out of the connecting seat 201, and the moving stroke of the inner core rod 301 is generally estimated, so as to pre-wind the threaded rod 202 and the wire rope loop, and to ensure that the threaded rod 202 is screwed into the connecting seat 201 deep enough to ensure enough friction and stability in a tensioned state, and ensure that the core rod body 1 is stable, but the threaded rod 202 cannot be screwed too much, so that the interference with the translation of the inner core rod 301 occurs, and the stroke of the inner core rod 301 is affected; when the device is unloaded, the device body can be easily taken out only by reversely twisting the knob; considering that the length of the hose is not fixed, the supporting position of the device body is not fixed, therefore, when the device body is designed, all manual operation space of the device body is compressed into the outer cylinder of the device body, so that even if the device body is deep into the hose, the expansion and lengthening of the elastic knob 203 can still be realized, the expansion, the retraction and other operations of the supporting mechanism 4 can be completed, and the practicability of the invention is greatly improved; meanwhile, in consideration of the fact that the pipe fittings of the fiber winding preparation process are not always parallel straight line pipe fittings in actual use, the fiber winding preparation process also comprises a plurality of main shapes such as a convex shape, a concave shape, a trapezoid shape and the like, aiming at the different shapes, the upper ends of the first supporting rod 401 and the second supporting rod 402 can be designed into detachable joint type movable supporting rods, in order to ensure the uniform expansion degree in the use process, the lower ends of the first supporting rod 401 and the second supporting rod 402 always adopt spherical rod heads 403 with the same size and model, and the actions of the main supporting group and the auxiliary supporting group are ensured to be always simultaneous and synchronous; on this basis, the model of the support rod at the upper end is changed, the expansion support of different types of inner surface pipe fittings can be realized, and the expansion range from the fully retracted state to the fully extended state is an effective expansion range.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the equivalent replacement or change according to the technical solution and the modified concept of the present invention should be covered by the scope of the present invention.
