Description

Auxiliary device for installing lining plate of water supply and drainage pipeline Technical Field The invention relates to the technical field of pipelines, in particular to an auxiliary device for installing lining plates of water supply and drainage pipelines. Background After municipal pipelines or other large pipelines are used for a long time, conditions such as corrosion or water leakage and the like can occur in the municipal pipelines or other large pipelines, even the phenomenon of pipe explosion occurs, and the pipe explosion frequency and the effect of the pipe explosion are aggravated year by year along with the increase of the service life and the damage of the pipelines. Most of the tubes are glass fiber reinforced plastic sand inclusion tubes, and the reasons are that the glass fiber reinforced plastic sand inclusion tubes and construction quality cannot meet the requirements, and structural defects are caused by long-term overrun load of the glass fiber reinforced plastic sand inclusion tubes, so that the tubes are burst. And when the pipeline is repaired in a full section, a lining stainless steel repair technology is generally adopted, a stainless steel plate is fed according to the inner diameter of the pipeline at a construction site, the stainless steel plate is conveyed into the pipeline, and the original pipeline is internally lined with the stainless steel and is tightly attached to the original pipeline for repair. In the construction process, the welding quality of the welding seam of the stainless steel plate is the key point of the control of the construction quality, and the traditional construction method is to stabilize and fix the stainless steel plate by manual assistance and then to weld the stainless steel plate in a segmented manner. In order to facilitate the support of a stainless steel lining plate, china patent No. CN218267925U discloses a stainless steel lining forming rounding device which comprises a first supporting part, a second supporting part and a stainless steel lining forming rounding device, wherein a swinging part is arranged above the first supporting part, a stop piece is arranged below the first supporting part, contact parts which are attached to the inner diameter of a pipeline are arranged at the end parts of the first supporting part and the second supporting part, and the stainless steel lining forming rounding device is provided, so that the stainless steel lining forming rounding device can support a stainless steel plate, ensure the attachment stability of the steel plate and the pipeline and improve the welding quality. In order to reduce the possibility that the expander falls off easily after the steel plate is supported, the direction of the supporting force of the expander on the steel plate is generally vertical to the inner wall of the pipeline as much as possible, namely, the extending direction of the expander is along the radial direction of the pipeline, but when the stainless steel lining plate at the horizontal position in the pipeline is supported by the patent, the position of the expander is required to be continuously adjusted, so that the supporting force of the expander on the lining plate is vertical to the inner wall of the pipeline, and the supporting force of the expander on the lining plate is relatively complicated. Disclosure of Invention In order to solve at least one technical problem mentioned in the background art, the invention aims to provide an auxiliary device for installing lining plates of water supply and drainage pipelines, which enables a pipe supporting device to be positioned quickly and is convenient for supporting the lining plates. In order to achieve the aim, the invention provides the technical scheme that the auxiliary device for installing the lining plate of the water supply and drainage pipeline comprises a bearing seat, wherein a moving mechanism is arranged on the lower side of the bearing seat, a first pipe supporting device is arranged on one side of the bearing seat, a second pipe supporting device is arranged on one side of the first pipe supporting device far away from the bearing seat, the second pipe supporting device is positioned in the middle of the first pipe supporting device, the first pipe supporting device comprises a first sealing block which is arranged on the bearing seat in a sliding manner along the vertical direction, a first sealing cavity is formed in the first sealing block in the vertical direction, a first air pump which is communicated with the first sealing cavity is arranged on the first sealing block, two first moving rods which move back are arranged on two sides of the first sealing cavity in a sliding manner, and a linkage mechanism which is used for enabling the two first moving rods to move equidistantly is arranged on the first sealing block. Further, the link gear is including rotating the first gear of installing in first sealing block, offer the cavity t
