[0025] As attached Figure 1 To the attached Figure 3 As shown:

[0026] The utility model provides a sandblasting and rust removal machine for accessories in a steel structure wind tower, comprising a sandblasting tank 1, a sandblasting pump device 2, a sandblasting tube 3, a sandblasting head 4 and a sandblasting extension arm 5. The sandblasting pump device 2 fixedly installed at the lower outside of the sandblasting tank 1 is connected to one end of the sandblasting tube 3, and the other end of the sandblasting tube 3 is connected to the sandblasting head 4. The sandblasting tube 3 and the sandblasting head 4 are respectively clamped and fixed on the two limiting clamps 52 of the sandblasting extension arm 5; the sandblasting extension arm 5 includes a handle extension arm rod 51 and a fastening bolt 53, two of the limiting clamps 52 are fixedly installed on the handle extension arm rod 51, and each of the limiting clamps 52 is installed with a fastening bolt 53, and the fastening bolt 53 controls the deformation of the limiting clamp 52 by locking; the handle extension arm rod 51 is located below the sandblasting tube 3 and the sandblasting head 4.

[0027] Furthermore, three legs 7 are cleverly fixed to the bottom of the sandblasting tank 1. Two of these legs are equipped with wheels 8, allowing the entire sandblasting machine to be easily moved within the work area, improving the equipment's flexibility and operating efficiency. The third leg 7 provides a stabilizing support, ensuring the stability of the sandblasting tank 1 during operation.

[0028] Furthermore, to further enhance the portability and operability of the device, a push rod 9 is fixedly mounted on the exterior of the sandblasting tank 1, making it easier for the operator to push the sandblasting machine for movement. Furthermore, a hook assembly is also provided on the exterior for hanging the sandblasting extension arm 5 and the lifting base 6. This design not only makes the device more compact, but also facilitates storage of the sandblasting extension arm 5 and the lifting base 6 when not in use.

[0029] Furthermore, the design of the sandblasting extension arm 5 fully considers operational flexibility and safety. One of the restraining clamps 52, which secures the sandblasting head 4, is rotatably connected to the shaft 64 of the support base 6. This design allows the sandblasting head 4 to remain stable while being able to rotate around the shaft to a certain angle, thus meeting the needs of rust removal at different angles and positions.

[0030] Furthermore, to ensure the stability of the sandblasting head during high-speed blasting, two limit plates 10 are fixedly mounted on the sandblasting head 4 in a mirror-symmetrical manner, and are closely located on both sides of the limiting clamp 52. This close contact design effectively prevents the sandblasting head 4 from shaking or falling off during operation, ensuring the safe execution of the rust removal operation.

[0031] Furthermore, the sandblasting extension arm 5 also incorporates ergonomic design, providing a more comfortable operating experience for the operator. An upper grip 55 and a lower grip 56 are respectively and fixedly installed on the grip extension arm rod 51, and the two are arranged on opposite sides of each other, facilitating the operator to choose the gripping method according to actual needs. The upper grip 55 adopts an "L" shape design, and its root is arc-shaped, effectively avoiding interference with the sandblasting pipe 3 or the sandblasting head 4. The lower grip 56 is vertically designed, providing another stable gripping option.

[0032] Furthermore, on one side of one of the restraint clamps 52, a shoulder rest 54 is also fixedly installed. The shoulder rest is designed with a "C"-shaped notch, which perfectly fits the human shoulder, and a soft pad is贴心地设置了软垫以增加舒适度。This design enables the operator to reduce the shoulder burden during long-term operation and improve work efficiency.

[0033] Furthermore, as an important component for supporting and rotating the sandblasting head, the lifting seat 6 is also精巧地 designed. The lifting seat consists of a support frame 61, mounting bolts 62 and a rotating seat 63. Both the support frame 61 and the rotating seat 63 adopt a "凵" shape structure. This design not only saves materials but also enhances the structural stability. A number of screw holes are linearly penetrated on both sides of the support frame 61 for installing the mounting bolts 62 to fix the rotating seat 63, and the height position of the rotating seat 63 is adjusted by拆卸安装螺栓62. Two symmetrical rotating shafts 64 are fixedly installed inside the rotating seat 63 for connecting and supporting the sandblasting head 4 to rotate.

[0034] Furthermore, to further improve the mobility and flexibility of the lifting seat 6, a self-locking universal wheel 65 is also fixedly installed at the bottom of the support frame 61. This enables the lifting seat to not only move freely on the ground but also fix its position through the self-locking function when needed, ensuring the stability of the sandblasting operation.

[0035] The working principle is as follows: First, when sandblasting and rust removal operations are required for the internal accessories of the steel structure wind tower, the operator places the sandblasting machine tank 1 at the designated position. Since three legs 7 are cleverly fixedly installed under the sandblasting machine tank 1, and two of the legs 7 are equipped with moving wheels 8, the entire sandblasting machine can be easily moved to an appropriate position within the working area. Subsequently, the third leg 7 is adjusted to ensure the stability of the sandblasting machine tank 1 and prevent shaking during the operation.

[0036] It should be noted that the part "贴心地设置了软垫以增加舒适度" and "拆卸安装螺栓62" in the original text seem to have some inaccuracies or unclear expressions. The above translation tries to make sense as much as possible based on the context.The operator then activates the sandblasting pump 2, located outside and below the sandblasting tank 1 and connected to one end of the sandblasting hose 3. The sandblasting pump 2 delivers the blasting material (such as garnet sand or quartz sand) from the sandblasting tank 1 at high speed through the sandblasting hose 3 to the sandblasting head 4. The sandblasting hose 3 and sandblasting head 4 are each secured to two restraining clamps 52 on the sandblasting extension arm 5. These restraining clamps are tightened with fastening bolts 53 to ensure the stability of the sandblasting hose 3 and sandblasting head 4 during operation.

[0037] The operator then grasps the upper handle 55 or lower handle 56 on the sandblasting extension arm 5, choosing the preferred grip. The upper handle 55 is L-shaped, with a curved base to prevent interference with the sandblasting tube 3 or sandblasting head 4. The lower handle 56 is vertical, providing a more stable grip. The design of the sandblasting extension arm 5 allows the operator to operate further away from the sandblasting source, improving operational safety.

[0038] Subsequently, the operator can change the position and angle of the sandblasting head 4 by moving the sandblasting extension arm 5. In particular, one of the limiting clamps 52 is rotatably connected to the rotating shaft 64 of the lifting seat 6, which allows the sandblasting head 4 to rotate around the rotating shaft at a certain angle while remaining stable. The lifting seat 6 is composed of a support frame 61, a mounting bolt 62 and a rotating seat 63. A self-locking universal wheel 65 is installed at the bottom of the support frame 61, which is convenient for movement and can be fixed in position when needed. The operator can flexibly adjust the angle and position of the sandblasting head 4 according to the specific position and shape of the accessories in the steel structure wind tower to achieve the best rust removal effect.

[0039] Finally, during the high-speed spraying process, the sandblasting head 4 is equipped with two mirror-symmetrical limit plates 10, which are tightly positioned on either side of the limiting clamp 52, effectively preventing the sandblasting head 4 from shaking or falling off during operation. Furthermore, the operator can utilize the "C"-shaped notch and cushioning of the shoulder support 54 to reduce shoulder strain during long-term work, improving work comfort and efficiency. Throughout the rust removal process, the sandblasting material precisely strikes the workpiece surface in the form of a high-speed jet, effectively sandblasting and removing rust from the accessories within the steel structure wind tower.

[0040] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
