The slider 23 is connected to the support frame 12, and the slider 23 is integrally manufactured with the support frame 12 in this embodiment. The rubber spreading base 11 is connected with 2 support frames 12 in a sliding mode through a sliding block 23.
The support frame 12 is connected with the rubber expansion pipe 13 through a rubber expansion pipe connecting mechanism. The hose expansion connection mechanism comprises a threaded rod 14. The support frame 12 is provided with a slide hole 15 along the length direction thereof. One end of the threaded rod 14 passes through the slide hole 15. The threaded rods 14 on the upper and lower sides of the support frame 12 are provided with nuts 20, and when the nuts 20 tightly abut against the side walls of the support frame 12, the threaded rods 14 are fixed with the support frame 12. The other end of the threaded rod 14 is in threaded connection with the rubber expansion pipe 13.

After the rubber expansion pipe 13 is aligned with the desulfurization pipe, the upper side wall and the lower side wall of the support frame 12 are tightly propped through the nuts 20, so that the position of the threaded rod 14 is fixed. Finally, the positioning nut is loosened to lower the arc-shaped protective cover 21, and when the arc-shaped protective cover 21 is lowered to a proper position, the positioning nut limits the position of the arc-shaped protective cover 21 on the threaded rod 14. Because the arc-shaped protective cover 21 is close to the support frame 12 first, the arc-shaped protective cover 21 does not limit the rotation of the threaded rod 14 in the installation process of the threaded rod 14 and the rubber expansion pipe 13, so that the threaded rod 14 and the rubber expansion pipe 13 cannot be in threaded connection.
When the rubber expansion pipe 13 expands the rubber on the rubber lining pipe, the air pump ventilates the airflow channel 18, the air is sprayed out through the air outlet 19, and the air generates an outward force on the rubber lining pipe in the spraying process, so that the rubber lining pipe is prevented from passing against the outer side wall of the rubber expansion pipe 13, and the friction damage of the rubber expansion pipe 13 to the rubber lining pipe is reduced.
Referring to fig. 3 and 4, before the rubber-lined pipe 2 on the outer side of the pipe body 1 is adhered to the flange, the pipe body 1 provided with the rubber-lined pipe 2 is expanded by a rubber-lined pipe expander so that the outer side wall of the rubber-lined pipe 2 is pressed against the inner side wall of the pipe body 1.
