[0031] Please refer to Figure 8-11 The long telescopic sootblower device 3 includes a sootblower beam structure, which includes a sootblower lower crossbeam plate 307 and a sootblower upper crossbeam plate 309. The sootblower lower crossbeam plate 307 and the sootblower upper crossbeam plate 309 are connected through a plurality of crossbeam support frames 304 and a connecting support plate 321. A motor mounting frame 316 is provided below the sootblower upper crossbeam plate 309. A sootblower servo motor 311 is installed at one end of the motor mounting frame 316. A driving sprocket shaft 315 is provided on the output shaft of the servo motor 311, and a long chain driving transmission sprocket 314 is rotatably provided on the driving sprocket shaft 315. A long chain driven sprocket 305 is provided on the lower surface of the end of the sootblower upper crossbeam 309 away from the sootblower servo motor 311. The long chain driving transmission sprocket 314 is connected to the long chain driven transmission sprocket 305 through a long chain 306, and a sootblower gun barrel 302 is installed in the sootblower beam structure.

[0033] An interface is reserved at the lower end of the sootblower barrel 302 , and a guide support pulley 323 assembly is installed through threads; a threaded barrel port interface 301 is reserved at the end of the sootblower barrel 302 .

[0034] The sootblower beam structure is supported by a plurality of support assemblies, each of which includes a sootblower column 303 and a triangular support foot 310 , and the triangular support foot 310 is fixed to the side of the sootblower column 303 .

[0035] Initially, the traverse hydraulic cylinder 101 and the lifting hydraulic cylinder 111 are in a closed state, the traverse base 106 is at the lowest end and the leftmost end, the pair of rollers 212 is at a minimum spacing state, and the sootblower barrel 302 is at the origin position.

[0036] When in use, the lifting hydraulic cylinder 111 is turned on to drive the transverse base 106 to rise. When the transverse base 106 rises to the highest point of the stroke, the transverse hydraulic cylinder 101 is turned on to drive the transverse base 106 to move horizontally. At this time, the steel pipe moves to the top of the steel pipe rotating device 2. The lifting hydraulic cylinder 111 is retracted and closed, and the steel pipe is separated from the transverse base 106 during the movement of the transverse base 106, and transitions to the steel pipe rotating device 2, and finally the transverse hydraulic cylinder 101 is retracted and closed, and the steel pipe transverse device 1 is in the initial state; when the steel pipe transitions to the steel pipe rotating device 2, the screw motor 219 is started, and the two sets of screw slider platforms 218 move away from both ends, and the distance between the roller wheels 212 is reasonably increased and adjusted, so that the height of the steel pipe axis is maintained at a fixed horizontal height, which is conducive to the soot blower gun barrel 302 entering the inner wall of the steel pipe for full coverage cleaning. After adjusting the distance between the roller wheels 212, the stepper motor 202 is started, and the roller wheels 212 are driven to rotate through the sprocket chain transmission relationship, thereby driving the steel pipe to rotate, which is conducive to increasing the effective contact area between the nozzle and the inner wall of the steel pipe and higher cleaning efficiency. At this time, start the sootblower servo motor 311 and open the pump valve to connect the long soft water pipe 318 to the water source, and use the sprocket chain transmission and the support pulley moving module to drive the sootblower gun barrel 302 to extend into the inner wall of the steel pipe to achieve full coverage cleaning of the inner wall of the steel pipe by the nozzle. Example 1

[0037] Taking a single steel pipe as an example, the specific process of steel pipe lateral cleaning is as follows: At the beginning, the lateral hydraulic cylinder 101 and the lifting hydraulic cylinder 111 are in the closed state, the stainless steel pipe is placed on the V-shaped frame of the lateral base 106, and is in the state of waiting for lateral movement. The lifting hydraulic cylinder 111 is pushed out first, the lateral base 106 rises first, and the lateral hydraulic cylinder 111 is pushed out later, and the lateral base 106 moves horizontally. At this time, the steel pipe is placed above the steel pipe rotating device 2, the lifting hydraulic cylinder 111 retracts part of the stroke, the steel pipe is transferred to the steel pipe rotating device 2, the lifting hydraulic cylinder 111 retracts all the stroke, and the steel pipe and the lateral moving device 14 are completely Separate, the lateral hydraulic cylinder 101 retracts the full stroke, at this time, the steel pipe lateral movement device 1 is in the initial state; the steel pipe is placed on the roller wheels on the steel pipe rotating device 2, and the screw motor 219 works to adjust the spacing of the roller wheels 212 according to the diameter of the steel pipe, so as to ensure that the axis of the steel pipe is always at the same horizontal height, and then the stepper motor 202 works to drive the two sets of active sprockets 1 204 and active sprockets 210 to work. The active sprockets 1 204 and active sprockets 210 are driven by the sprocket chains. The mechanical matching relationship drives the driven sprocket 1 207 and the driven sprocket 2 208 to rotate, thereby driving the roller wheel 212 to rotate, and then driving the long steel pipe 4 to support the self-rotation function; at this time, the long steel pipe 4 is in self-rotation on the steel pipe rotating device 2, and the soot blower servo motor 311 starts to work and drives the long chain active transmission sprocket 314 to rotate, thereby driving the long chain 306 to rotate; the long chain 306 is fixedly connected to the barrel chain connecting device 312, and the barrel chain connecting device 312 is fixedly connected to the soot blower barrel 302, and the long chain The rotation of bar 306 drives the soot blower barrel 302 fixedly connected thereto to move forward and extend. The soot blower barrel port interface 301 has an internal thread interface connected to the self-rotating nozzle, thereby realizing full coverage cleaning of the dirt on the inner wall of the steel pipe by the soot blower. When the soot blower barrel port 301 moves to the end of the steel pipe, the soot blower completes the cleaning of the inner wall of the steel pipe. Then, the soot blower servo motor 311 rotates in the opposite direction, the water valve of the water pipe is closed, and the soot blower barrel 302 returns to the initial position, waiting for the next steel pipe to move horizontally to the steel pipe rotating device 2.
