[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0015] Reference Figure 1 , 3 As shown in Figure 4, a device for peeling the outer shell of an insulated pipe includes a blade holder assembly and a pipe conveying assembly for driving the pipe in a spiral motion. The pipe conveying assembly includes a conveying frame 1 and a drive mechanism. Two rows of conveying wheels 2 are mounted on the conveying frame 1, and all conveying wheels 2 are inclined to one side. The adjacent shafts of one row of conveying wheels 2 are connected by a universal coupling 3. The drive mechanism is used to drive that row of conveying wheels 2. Because all conveying wheels 2 are inclined to one side, the two rows of conveying wheels 2 can drive the pipe in a spiral motion.

[0016] The tool holder assembly includes a gantry frame, a lifting beam 6, and a tool holder 12. The gantry frame includes a crossbeam 4 and two columns 5, which are located on the left and right sides of the conveyor frame 1, respectively. The lifting beam 6 is located below the crossbeam 4, and its left and right ends are slidably connected to the two columns 5, respectively. The lifting beam 6 is connected to the crossbeam 4 through a lifting drive mechanism. The tool holder 12 is slidably mounted on the lifting beam 6, and the two are connected through a reciprocating drive mechanism. A shovel 13 is mounted on the bottom of the tool holder 12. In this embodiment, the shovel 13 is arranged vertically.

[0017] In use, first adjust the position of the scraper 13 according to the pipe specifications: the reciprocating drive mechanism drives the blade holder 12 to move laterally to the designated position, at which point the scraper 13 corresponds to one side of the pipe's central axis; the lifting drive mechanism drives the lifting beam 6 to descend to the designated height, at which point the lower blade of the scraper 13 can contact the outer wall of the pipe's steel pipe; then the pipe slides from the loading rack between the two rows of conveyor wheels 2, the drive mechanism is started, and the two rows of conveyor wheels drive the pipe to move spirally; when the pipe passes under the blade holder assembly, the lower blade of the scraper 13 contacts the outer wall of the pipe's steel pipe, thereby removing the polyurethane insulation layer on the pipe. Example 2

[0018] As a preferred embodiment of this utility model, this embodiment designs the lifting drive mechanism and the reciprocating drive mechanism based on Embodiment 1, specifically as follows: The lifting drive mechanism includes a first motor 7, a first nut 8, and a first lead screw 9. The first motor 7 is fixed to the top of the crossbeam 4, and a mounting bracket 10 is fixed to the top of the crossbeam 4. The first nut 8 is vertically rotatably installed inside the mounting bracket 10, and its outer wall is connected to the output shaft of the first motor 7 through a chain 11. The first lead screw 9 vertically passes through the mounting bracket 10 and the crossbeam 4, and is threadedly connected to the first nut 8. Its lower end is fixed to the top of the lifting beam 6.

[0019] More specifically, there are two sets of lifting drive mechanisms, which are symmetrically arranged on the left and right and operate synchronously.

[0020] When in operation, the first motor 7 is started, which drives the first nut 8 to rotate through the chain 11, thereby driving the lifting beam 6 to move up and down through the first lead screw 9.

[0021] The reciprocating drive mechanism includes a second motor 14, a second nut 16, and a second lead screw 15. The second motor 14 is fixed to the bottom of the lifting beam 6, the second nut 16 is fixed to the tool holder 12, and the second lead screw 15 is arranged parallel to the lifting beam 6. It passes through the tool holder 12 and is threadedly connected to the second nut 16. One end of the lead screw 15 is connected to the output shaft of the second motor 14 through a coupling.

[0022] More specifically, both the first motor 7 and the second motor 14 are geared motors.

[0023] During operation, the second motor 14 is started, which drives the second lead screw 15 to rotate, thereby causing the tool holder 12 to move laterally through the second nut 16. Example 3

[0024] As a preferred embodiment of this utility model, this embodiment differs from Embodiment 1 in that: (Refer to...) Figure 2 As shown, the blade holder 12 of this embodiment is equipped with two blades 13, one in front and one behind. The two blades 13 are located on the same vertical plane, and the lower end of the front blade 13 is higher than the lower end of the rear blade 13.

[0025] When adjusting the position of the scraper 13, the lower edge of the rear scraper 13 should be able to contact the outer wall of the steel pipe. During operation, the front scraper 13 first removes the surface polyurethane insulation layer, and then the rear scraper 13 removes the remaining polyurethane insulation layer.

[0026] Using two scrapers 13, one at the front and one at the back, allows for the removal of the polyurethane insulation layer in layers, which helps reduce the working pressure on the scraper 13 and extend its service life.

[0027] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
