Problems solved by technology

[0006] However, in the traditional lining material reversing device, since the pipe lining material before reversing is stored in the storage container in a folded state, the pull-out resistance during reversing is too large, requiring a large reversing pressure
[0007] In addition, since the pipe lining material is stored in a folded state, when it is pulled out, the folded upper pipe lining material will fluctuate up and down according to the amount of extraction, resulting in the failure to pull out smoothly

Embodiment Construction

[0028] In the present invention, an electric motor is used to wind the pipe lining material on a rotating body such as a reel, and when the pipe lining material is reversed, the electric motor is operated as a generator, and a brake is applied to the withdrawal of the pipe lining material , Hereinafter, embodiments of the present invention will be described based on the drawings.

[0029] Figure 1~3 It shows the composition of the lining material reversing device, and the symbol 10 is a storage container with a closed structure for storing the lining material of the pipe, usually as figure 1 As shown, it is assembled on the loading platform of a truck through the support plates 11 and 12 and transported to the job site. The support plate 12 is provided with ribs 12a, 12b extending in the horizontal direction for reinforcing the support plate. The support plate 11 is also provided with identical ribs 11a, 11b (please refer to image 3 ). In addition, vertical adjustment me...

Abstract

A pipe lining material is wound in a roll on a rotary body (22) using an electric motor (21), and stored in a storage container (10). Wen everting, compressed air is applied within the storage container (10) to pull the lining material from the storage container and evert it via an eversion nozzle (40) attached to the storage container. At this time, the electric motor (21) functions as an electric generator and brakes the pullout of the pipe lining material (1). With such a constitution, the pullout speed of the pipe lining material is substantially constant and the pipe lining material can be smoothly everted with little pullout resistance.

Description

technical field [0001] The present invention is an inner lining material reversing device, in detail, it is used to apply an inner lining material to the inner surface of an old and corroded existing pipeline to repair the inner lining material of the existing pipeline. Material reversal device. Background technique [0002] There is a pipe lining construction method that has been actually adopted. When the existing pipes such as sewer pipes, gas pipes, communication cable pipes, and cable pipes buried underground are old and corroded, there is no need to dig out the existing pipes from the ground. road, but apply a lining to its inner surface to restore the pipeline. [0003] One of the above-mentioned pipe lining methods is known to be constructed with a pipe lining material in which an unhardened liquid curable resin is impregnated on a tubular resin adsorbent whose outer surface is airtightly covered with a plastic film. In this construction method, when the lining mat...
