As shown in fig. 1 to 4, the present utility model provides a technical solution:

the utility model provides a scrape pipe scraper for sheathed tube, including scraping the pipe 1, scrape the pipe 1 and include barrel housing 103, a series of heliciform is scraped tooth spout 104 has been seted up to barrel housing 103's surface, through scraping tooth spout 104 sliding connection to have and scrape tooth mobile device 2, scrape tooth mobile device 2 include with scrape tooth spout 104 one-to-one scrape tooth carriage 208, the bottom fixedly connected with of every and scrape tooth carriage 208 scrapes tooth attachment strip 207, one side fixedly connected with of every and scrapes tooth attachment strip 207 scrapes tooth main part 206 in a set of, one end fixedly connected with scrapes tooth mount 205, every scrapes tooth mount 205 respectively with the bottom fixed connection who encloses into the inner wall of scraping tooth spout 104. The scraping sliding frame 208 can slide down along the scraping sliding groove 104, the scraping attaching band 207 is formed by hinging a plurality of metal sheets, and the bending of the scraping attaching band is limited, so that during the sliding down process, the scraping attaching band 207 bulges outwards, and the scraping main body 206 is pushed outwards, so that the scraping main body can be contacted with the inner wall of the petroleum pipe. Simultaneously, the outer sides of all the scraping tooth sliding frames 208 are fixedly connected with a rotating frame 204, and the inner sides of the rotating frame 204 are in sliding sleeve joint with the cylinder shell 103. The wiper blade carrier 208 is therefore limited to the same height, and the individual wiper blade bodies 206, which are located at the same height, are always at the same height. The top end of the rotating frame 204 is fixedly connected with a series of pushing rod bodies 203, and the top ends of all pushing rod bodies 203 are fixedly connected with a driving turntable 202. The inside of the cylinder shell 103 is fixedly connected with a threaded rod 102, the outside of the threaded rod 102 is rotationally screwed with the inside of the driving turntable 202, and the top end of the threaded rod is fixedly connected with an extension rod 101. In this embodiment, when the pipe scraping operation is performed, the extension rod 101 needs to be fixedly connected with a driving device, so that the pipe scraper is inserted into the petroleum pipe and moves along the petroleum pipe, and thus the extension rod 101 is kept still during the process, and thus the driving turntable 202 is rotated, and the driving turntable 202 moves up and down according to the rotation direction. In the present embodiment, when the rotation direction is consistent with the rotation direction of the scraping sliding groove 104, the driving turntable 202 descends to prop up the scraping sliding frame 208, and otherwise ascends, so that the scraping sliding frame 208 is leveled. The inner bottom end of the driving turntable 202 is fixedly connected with a guard plate moving device 3, the guard plate moving device 3 comprises a plurality of follow-up push rods 306, the bottom ends of all the follow-up push rods 306 are jointly clamped with a guard plate lifting platform 303 and communicated to the lower side of the guard plate lifting platform 303, and the threaded rod 102 penetrates through the inner side of the guard plate lifting platform 303. In this embodiment, the apron elevating platform 303 and the threaded rod 102 are not in direct contact, and thus the elevating rotation state of the apron elevating platform 303 is completely dependent on the driving turntable 202. The outside rotation of backplate lift platform 303 is connected with a series of linkage bull stick 305, and the outside of every linkage bull stick 305 all rotates and is connected with a backplate main part 301, and the top sliding connection of barrel housing 103 has a series of backplate slide frame 302, and every backplate slide frame 302 all is with a backplate main part 301 sliding connection respectively. In this embodiment, each guard plate sliding frame 302 includes two clamping plates at two sides and a middle sliding rod, meanwhile, a sliding groove penetrating through the guard plate sliding frame is formed in the side surface of the guard plate main body 301, when the guard plate lifting platform 303 descends, the linkage rotating rod 305 is driven to descend and incline, the guard plate main body 301 is extruded from one end of the linkage rotating rod 305 and naturally rotates along the sliding rod, and under the further pulling of the linkage rotating rod 305, the guard plate main body can slide down for the sliding groove, and vice versa, so that extension and retraction of the guard plate are realized. Meanwhile, the push rod buckle 304 is fixedly connected to the bottom end of each follow-up push rod 306 and can be connected with the clamping groove at the bottom end of the guard plate lifting platform 303 in a clamping mode, so that when the guard plate is contracted to the limit and the scraping teeth still need to be outwards expanded, the buckle can be separated from the clamping groove, the scraping teeth can continue to be outwards expanded, and when the scraping teeth are contracted, the guard plate can extend out in the rising of the lifting platform along with the contact of the buckle and the clamping groove, and the scraping teeth are protected. The top end of the driving turntable 202 is fixedly connected with a rotating handle 201, and the outer side of the extension rod 101 is in sliding connection with the inside of the rotating handle 201. In this embodiment, a rotating rod is provided at the top of the rotating handle 201, and in this embodiment, the rotating rod is formed by a plurality of sleeves of rods which are mutually clamped, so that the rotating rod can extend out of the petroleum pipe, and the rotating disc 202 is convenient for a worker to rotate.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
