[0020] The present application will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0021] like Figure 1-5As shown, a heating device for anti-corrosion and thermal insulation pipe spraying comprises a support frame 1, a sliding seat 2, a rotating sleeve 3 and a heating coil 4; the sliding seat 2 is axially slidably arranged on the support frame 1 along the rotating sleeve 3, the rotating sleeve 3 is rotatably arranged on the sliding seat 2 along its own axis, and the heating coil 4 is located inside the rotating sleeve 3; along the extension direction of the heating coil 4, the pitch of the heating coil 4 gradually increases, and the diameter of the heating coil 4 gradually increases.

[0022] The heating coil 4 enters from one end of the rotating sleeve 3 and does not contact the interior of the rotating sleeve 3 .

[0023] The entire rotating sleeve 3 can rotate along its own axis, so that the workpiece fixed inside the rotating sleeve 3 rotates with the rotating sleeve 3 to achieve uniform heating.

[0024] The heating coil 4 is spring-shaped. As it goes deeper into the rotating sleeve 3, the pitch of the heating coil 4 gradually increases, and the diameter of the heating coil 4 also gradually increases. That is, as it goes deeper into the rotating sleeve 3, the heating effect of the heating coil 4 on the steel pipe gradually decreases. Therefore, in actual use, the sliding seat 2 can be made to slide relative to the support frame 1 according to different requirements of the steel pipe, thereby achieving different heating requirements for the steel pipe.

[0025] In some further embodiments, a power supply 5 is further included, and the heating coil 4 is connected to the power supply 5 .

[0028] The sliding between the sliding seat 2 and the support frame 1 is achieved through the sliding block and the slide rail. By moving the sliding seat 2, the position of the steel pipe in the heating coil 4 can be changed, thereby achieving different degrees of heating requirements.

[0029] In some further embodiments, a clamping ring 6 is provided inside the rotating sleeve 3 , and the clamping ring 6 is connected to the inner wall of the rotating sleeve 3 via a connecting arm 61 . An abutment bolt 60 is radially threaded onto the clamping ring 6 .

[0031] The abutment bolt 60 is used to limit the position of the steel pipe. When the steel pipe is located in the clamping ring 6, the abutment operation of the steel pipe can be achieved by tightening the abutment bolt 60 inward.

[0032] In some further embodiments, an auxiliary roller 64 is further included. The auxiliary roller 64 is rotatably connected to the adjustment rod 63. The adjustment rod 63 is radially slidably arranged on the mounting bracket 62 along the rotating sleeve 3. The mounting bracket 62 is arranged on the inner wall of the rotating sleeve 3.

[0033] The auxiliary roller 64 is mainly used to realize the axial movement of the steel pipe relative to the rotating sleeve 3. The mounting frame 62 is a plate-shaped structure, and the adjusting rod 63 is a U-shaped structure. The auxiliary roller 64 is rotatably set in the middle position of the adjusting rod 63. The two ends of the adjusting rod 63 slide through the adjusting frame, and two adjusting bolts are screwed on both ends of the adjusting rod 63. The two adjusting bolts are respectively located on both sides of the adjusting frame to fix the adjusting rod 63 after the adjustment of the adjusting rod 63 is completed.

[0034] Two sets of auxiliary rollers 64 , adjustment rods 63 , and mounting brackets 62 are provided correspondingly.

[0035] In some further embodiments, a driving shaft 20 and a driven shaft are rotatably provided on the sliding seat 2, the driving shaft 20 and the driven shaft are spaced apart, one end of the driving shaft 20 is connected to the transmission end of the motor 22, and a rotating disk 21 is provided on the driving shaft 20 and the driven shaft, and the rotating disk 21 is rollingly connected to the outer wall of the rotating sleeve 3.

[0036] The motor 22 controls the driving shaft 20 to rotate, and the driving shaft 20 drives the rotating disk 21 thereon to rotate, thereby realizing the rotation of the rotating sleeve 3.

[0037] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description.
