[0003] The Chinese patent discloses a long blow bracket added to a long telescopic soot blower for boilers (the authorization announcement number is: CN220436546U), which provides multiple support points for the soot blowing gun barrel through the cooperation of the front bracket and multiple in-furnace bracket mechanisms, solving the problem that the soot blowing gun barrel is bent due to its own gravity because it is in a suspended state for a long time, greatly reducing the labor intensity of personnel frequently replacing the soot blowing gun barrel. However, since the limiting sleeve is sleeved outside the soot blowing gun barrel, although the soot blowing gun barrel can rotate in the limiting sleeve, when the soot blowing gun barrel is moving and rotating continuously, it is easy to generate friction with the limiting sleeve, which will not only generate abnormal noises, but also cause scratches on the surface of the soot blowing gun barrel, etc., and cannot improve the smoothness of the soot blowing gun barrel when it is moving.

One end of the valve 31 is fixedly communicated with an inner pipe 32. One end of the inner pipe 32 is sleeved with an outer pipe 33. A supporting mechanism 4 is installed on the support frame 2. The supporting mechanism 4 includes a connecting rod 41, an adjusting frame 42 and a reinforcing rod 43. Adjusting frames 42 are fixedly connected to both ends of the connecting rod 41, and two symmetrically distributed reinforcing rods 43 are fixedly connected to the top of the connecting rod 41. A bolt 44 is threadedly connected to the adjusting frame 42. The tops of the two reinforcing rods 43 are fixedly connected to an arc plate 45. Three rollers 46 are fixedly connected to the inner arc surface of the arc plate 45. The adjusting frame 42 is slidably sleeved outside the support frame 2. One end of the bolt 44 abuts against the support frame 2. The reinforcing rods 43 are obliquely distributed. All three rollers 46 abut against the periphery of the outer pipe 33. The supporting mechanism 4 can support the outer pipe 33, and at the same time of supporting, it can also reduce the wear of the outer pipe 33, prevent the outer pipe 33 from generating friction with other components during the traveling process, resulting in abnormal noises or scratches, etc. Moreover, the height of the supporting mechanism 4 is adjustable, so that the rollers 46 can always be in contact with the outer pipe 33, making the outer pipe 33 travel more smoothly.

[0021] A transmission mechanism 5 is installed on the outer pipe 33. The transmission mechanism 5 includes a first motor 51, a lead screw 52, and an adjustment plate 53. The first motor 51 is fixedly connected to the mounting bracket 3, and the driving end of the first motor 51 penetrates through the mounting bracket 3 and is fixedly installed with a lead screw 52. An adjustment plate 53 is sleeved on the external thread of the lead screw 52. Two guide blocks 54 are fixedly connected to the top of the adjustment plate 53. One end of the lead screw 52 is rotatably connected to a fixed plate 55 through a bearing. The fixed plate 55 is fixedly connected to the bottom of the cross beam 1. The guide blocks 54 are slidably connected inside the guide groove 11. A second motor 6 is fixedly connected to the adjustment plate 53, and the driving end of the second motor 6 penetrates through the adjustment plate 53 and is fixed to a first gear 61. A second gear 62 is fixedly sleeved on the outside of the outer pipe 33. The adjustment plate 53 is slidably sleeved on the outside of the inner pipe 32.

[0023] Working principle: When using this device, first loosen the bolt 44, then hold the connecting rod 41 and move it upward until the three rollers 46 abut against the periphery of the outer pipe 33. Then tighten the bolt 44. Then control the first motor 51 and the second motor 6 to work. After the second motor 6 is powered on, it can drive the first gear 61 and the second gear 62 to rotate, thereby driving the outer pipe 33 to rotate. After the first motor 51 rotates forward, it can drive the lead screw 52 to rotate forward. Through the guiding function of the guide block 54 in the guide groove 11, the adjustment plate 53 can be driven to continuously move to the right, and then the rotating outer pipe 33 can be driven to continuously move to the right until the outer pipe 33 moves into the boiler. Then open the valve 31. At this time, the gas enters the outer pipe 33 through the inner pipe 32 and is discharged from the end of the outer pipe 33 for soot blowing, so that the inside of the boiler can be cleaned in multiple directions.
