[0035] The present invention will be further described with reference to the following embodiments.

[0036] Example 1.

[0037] like Figure 1-4 As shown, an oil pipeline peeling machine includes a heating main unit 1, which is electrically connected to a power supply 2 and a heating arc plate 3, and the heating arc plate 3 is provided with a heating surface 4 and a back surface 5. A heating coil is installed inside the heating arc plate 3, and an adjustment scraping mechanism is installed at one end of the back surface 5. The heating arc plate 3 is movably fitted with the outer wall of the oil pipeline 6, and the adjustment scraping mechanism is coordinated with the outer wall of the oil pipeline 6 for movably scraping.

[0038] The present application is used to peel and scrape the 3PE anti-corrosion layer on the outside of the oil pipeline 6. First, the heating host 1 is connected to the power supply 2, and then the heating coil is heated by the heating host 1, so that the heating arc plate 3 generates heat. The 3PE anti-corrosion layer on the outside of the oil pipeline 6 is heated by fitting the heating arc plate 3 with the oil pipeline 6. When the temperature rises to a level that can soften the 3PE anti-corrosion layer, the heating arc plate 3 can be rotated, and the softened 3PE anti-corrosion layer can be peeled and scraped by adjusting the scraping mechanism. A control panel is provided on the heating host 1, and a power switch, a start switch, a temperature display and a voltage display panel are provided on the control panel. The power switch controls the power supply of the entire equipment. After power is supplied, an instruction is sent to the heating coil through the start switch for heating. The power supply 2 adopts a 380VAC / 50HZ power supply 2.

[0039] The adjusting scraping mechanism includes a bending positioning plate 7, which is fixedly mounted on the back side 5. Two adjusting screws 8 are spirally mounted on the bending positioning plate 7. A fixed plate 9 is rotatably mounted on the end of the adjusting screw 8 close to the oil pipeline 6. A scraping adjusting assembly 10 is mounted on the fixed plate 9. The scraping adjusting assembly 10 is movably scraped in cooperation with the oil pipeline 6.

[0040] The adjustable scraping mechanism is fixedly mounted on one end of the back side 5 through the bending positioning plate 7. At the same time, the rotation direction of the heating arc plate 3 is toward the end away from the bending positioning plate 7. The relative distance between the fixed plate 9 and the oil pipeline 6 can be adjusted on the bending positioning plate 7 by adjusting the screw 8, so that the scraping adjustment component 10 is in contact with the oil pipeline 6. When the heating arc plate 3 rotates, the 3PE anti-corrosion layer on the outer wall of the oil pipeline 6 can be peeled and scraped off by the scraping adjustment component 10.

[0041] The scraping adjustment assembly 10 includes positioning side plates 101 installed at both fixed ends, and a scraper 102 is rotatably installed between the two positioning side plates 101. The two sides of the scraper 102 are rotatably installed on the two positioning side plates 101 through a rotating shaft 107. The rotating shaft 107 extends to the outside of the positioning side plates 101 and is fixedly installed with a turntable 103. Each positioning side plate 101 is provided with a first threaded positioning hole 104, and the turntable 103 is provided with a plurality of second threaded positioning holes 105 in a surrounding array. The first threaded positioning hole 104 is movably corresponding to the second threaded positioning hole 105, and a locking screw 106 is spirally installed inside the first threaded positioning hole 104 and the second threaded positioning hole 105 corresponding to the first threaded positioning hole 104.

[0042] The scraping adjustment assembly 10 peels and scrapes the outer wall of the oil pipeline 6 by rotating the scraper 102 installed on the two positioning side plates 101. The scraper 102 can adjust the angle with the outer wall of the oil pipeline 6 through the turntable 103. It is suitable for oil pipelines 6 with different curvatures. After adjusting to the appropriate angle, the locking screw 106 is simultaneously screwed into the first threaded positioning hole 104 and the second threaded positioning hole 105 to fix the fitting angle of the scraper 102 and the oil pipeline 6.

[0043] A discharge slot 11 is provided between the scraper 102 and the fixed plate 9 .

[0044] The scraper 102 scrapes off the 3PE anti-corrosion layer on the outer wall of the oil pipeline 6 and discharges the material through the discharge slot 11 to prevent the 3PE anti-corrosion layer from accumulating at the scraper 102 position.

[0045] A hexagonal nut 12 is mounted on one end of the adjusting screw 8 , and a limiting disc 13 is mounted on the other end. The limiting disc 13 and the adjusting screw 8 are rotatably mounted with the fixing plate 9 .

[0046] The adjusting screw 8 is rotatably mounted inside the fixing plate 9 via the limiting disc 13 , thereby driving the fixing plate 9 to move linearly.

[0047] Two heated handles 14 are fixedly mounted on the back side 5 .

[0048] The heated handle 14 is made of insulating material to ensure operator safety.

[0049] The utility model heats the heating coil through the heating main unit 1, and then heats the outer wall of the oil pipeline 6 by the heating arc plate 3. Then, the heating arc plate 3 is rotated to peel off the 3PE anti-corrosion layer on the oil pipeline 6 by adjusting the scraping mechanism. The scraping adjustment component 10 can be used to adjust the angle between the scraper 102 and the oil pipeline 6 to adapt to oil pipelines 6 of different diameters, and can be adjusted according to the thickness of the 3PE anti-corrosion layer, thereby improving the applicability of the oil pipeline 6 peeling machine.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
