Description

Technical Field

[0001] This utility model relates to an automated sandblasting equipment, specifically an automated sandblasting mechanism for the exterior facade of a platform-type steel tower. Background Technology

[0002] In the painting operations of large cable tower segments in the factory, automated spraying mainly provides various solutions for the exterior of the workpiece. When the workpiece itself is more than 5m high (including the support), conventional paint booths cannot meet the requirements for the installation of overhead crane-type spraying robots in terms of height. Therefore, it is usually necessary to use some small mobile devices with attached robotic arms for operation. This operation method has a high degree of human intervention, high labor intensity, low operation efficiency, and high operation cost. On the other hand, due to the inconvenience of robotic arm movement and the limited swing range, the overall sandblasting efficiency is low and the sandblasting effect is poor. Furthermore, since the sandblasting end needs to swing continuously, conventional sandblasting mechanisms often have problems such as sandblasting guide detachment and difficulty in controlling the sandblasting angle range due to the relatively large stress of the spray during sandblasting. This makes it difficult to ensure the safety of workers. In particular, the existing sandblasting mechanism is also prone to the problem of sandblasting splash. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a special sandblasting mechanism for the exterior of steel towers that features continuous operation, long-lasting durability, high work efficiency, good sandblasting effect, and good safety.

[0004] To solve the above-mentioned technical problems, the present invention provides a special sandblasting mechanism for the exterior of steel towers, comprising a mobile platform vehicle, a longitudinal moving platform mounted on the mobile platform vehicle capable of reciprocating along the longitudinal direction of the mobile platform vehicle, and a transverse moving platform mounted on the longitudinal moving platform capable of reciprocating laterally along the longitudinal moving platform. A sandblasting robotic arm capable of rotating on the transverse moving platform is mounted on the transverse moving platform. A sandblasting swing head for sandblasting the exterior of the steel tower is installed at the end of the sandblasting robotic arm. A double-angled sandblasting conduit is fixedly installed on the sandblasting swing head. The double-angled sandblasting conduit has an upper fixed pipe that is inclined upwards and a lower fixed pipe that is inclined downwards, forming a sandblasting angle of 65-85° between the upper fixed pipe and the lower fixed pipe.

[0005] The double-angled sandblasting guide also includes a U-shaped component with a mounting sleeve. An upper inclined block and a lower inclined block are respectively provided on the two side walls of the U-shaped component. The upper fixed pipe is provided on the upper inclined block, and the lower fixed pipe is provided on the lower inclined block. The double-angled sandblasting guide is installed on the swing head rotation shaft of the sandblasting swing head through the mounting sleeve on the U-shaped component.

[0006] Both the upper and lower fixing tubes are open tubes with two connecting lugs.

[0007] The sandblasting robotic arm includes a rotating seat mounted on a transverse moving platform, a main arm rotatably mounted on the rotating seat, a swingable large arm mounted via the main arm's rotating shaft, a swingable small arm seat mounted via the large arm's rotating shaft, a small arm rotatably mounted on the small arm seat, and a swinging seat mounted at the end of the small arm. The sandblasting swing head is mounted on the swinging seat and can swing under the drive of the swinging seat.

[0008] The longitudinal moving platform has guide rails arranged along the width direction of the moving platform vehicle, and the bottom of the transverse moving platform is provided with a sliding groove that cooperates with the guide rails. The width of the transverse moving platform is smaller than the width of the longitudinal moving platform and it can reciprocate within the width range of the longitudinal moving platform.

[0009] The mobile platform vehicle is equipped with wheels and a drive unit at the bottom to drive the wheels.

[0010] The arm span of the sandblasting robotic arm is 5-8m.

[0011] The advantages of this utility model are:

[0012] The mobile platform vehicle features a longitudinal moving platform, a transverse moving platform, a sandblasting robotic arm with a sandblasting swing head mounted on the transverse moving platform, and a double-angled sandblasting guide fixedly installed on the sandblasting swing head, creating a sandblasting angle of 65-85°. This allows the sandblasting swing head to be moved to the outer facade of the steel tower for sandblasting as needed, offering convenient, reliable, and easy-to-control operation. Furthermore, it effectively controls the sandblasting angle range, ensuring worker safety. The double-angled structure ensures perfect and even coverage of the set area, preventing any areas from remaining rust and significantly improving the sandblasting effect. The angled design of the two fixed tubes also ensures that the sand particles at the blasting nozzles... The impact forces are partially offset, effectively mitigating sand splashing during automated sandblasting operations and further ensuring the safety of operators. Furthermore, the sandblasting robotic arm, equipped with a sandblasting swing head on a platform capable of multiple degrees of freedom, fulfills sandblasting needs from various angles, further improving the quality of sandblasting and rust removal. While improving the efficiency and quality of flat coating work using automated equipment, it simplifies equipment operation and workflow, and allows free access to the factory, increasing site utilization and facilitating future maintenance and upgrades. Finally, the width of the lateral moving platform is smaller than that of the longitudinal moving platform, allowing it to reciprocate within the width range of the longitudinal moving platform, resulting in excellent stability within a certain movement space.

[0019] The following detailed description of the special sandblasting mechanism for the exterior of steel towers, in conjunction with the accompanying drawings and specific embodiments, will further illustrate this utility model.

[0020] As shown in the figure, the special sandblasting mechanism for the exterior of steel towers of this utility model includes a mobile platform vehicle 1, a longitudinal moving platform 2 mounted on the mobile platform vehicle that can reciprocate along the longitudinal direction of the mobile platform vehicle, and a transverse moving platform 3 mounted on the longitudinal moving platform 2 that can reciprocate laterally along the longitudinal moving platform. The longitudinal moving platform 2 has guide rails 21 arranged along the width direction of the mobile platform vehicle. The bottom of the transverse moving platform 3 is provided with a groove that cooperates with the guide rails. The width of the transverse moving platform 3 is smaller than the width of the longitudinal moving platform, allowing it to reciprocate within the width range of the longitudinal moving platform, thereby restricting the transverse moving platform... The 3-meter range of movement improves the accuracy of the movement position and ensures the stability of the entire device. The bottom of the mobile platform vehicle 1 is equipped with traveling wheels 22 and a drive device for driving the traveling wheels. A sandblasting robotic arm 4 that can rotate on the horizontal moving platform 3 is installed. The arm span of the sandblasting robotic arm 4 is 5-8m, preferably 6m. The end of the sandblasting robotic arm 4 is equipped with a sandblasting swing head 5 for sandblasting the exterior of the steel tower. A double-angled sandblasting duct 6 is fixedly installed on the sandblasting swing head 5. The double-angled sandblasting duct 6 includes a U-shaped part 9 with a mounting sleeve 12. The two side walls of the U-shaped part 9 are respectively equipped with The system consists of an upper inclined block 10, a lower inclined block 11, an upper fixed pipe 7 mounted on the upper inclined block 10, and a lower fixed pipe 8 mounted on the lower inclined block 11. The inclination angles of the upper inclined block 10 and the lower inclined block 11 are designed so that the upper fixed pipe 7 tilts upwards and the lower fixed pipe 8 tilts downwards, forming a sandblasting angle of 65-85° between the upper fixed pipe 7 and the lower fixed pipe 8. In other words, the double-inclination sandblasting guide is composed of a U-shaped component with upper and lower inclined blocks and upper and lower fixed pipes mounted on the upper and lower inclined blocks. The upper and lower inclined blocks of the U-shaped component have an angle of 74.63°, and the upper and lower fixed pipes and the upper and lower inclined blocks are parallel to each other. This structural design allows us to control the sandblasting angle at 74.63°. Through testing, it was found that a sandblasting angle of 70°~80° generally yields the best results. Field operation verification showed that 74.63° is the most effective. By moving the longitudinal and lateral moving platforms and swinging the sandblasting robotic arm 4, the sandblasting head 5 can be positioned on the outer facade of the steel tower for sandblasting operations. During operation, the mobile platform vehicle is controlled to move to the work area. By adjusting the longitudinal and lateral moving platforms and the movement of the sandblasting robotic arm with a reach of 6m, the sandblasting gun can be aligned with the sandblasting position for sandblasting operations.

[0021] Furthermore, the aforementioned double-angled sandblasting guide tube 6 is mounted on the swing head rotation shaft of the sandblasting swing head 5 via the mounting sleeve on the U-shaped part. Meanwhile, the aforementioned upper fixed tube 7 and lower fixed tube 8 are both open tubes with two connecting ear plates. Both open tubes with two connecting ear plates are fixed with a row of bolts, which is very safe.

[0022] Furthermore, the aforementioned sandblasting robotic arm 4 includes a rotating base 13 mounted on a transverse moving platform, a main arm 14 (rotating) rotatably mounted on the rotating base, a swingable large arm 16 (swinging) mounted via the main arm rotation shaft 15 of the main arm 14, a swingable small arm base 18 (swinging) mounted via the large arm rotation shaft 17 of the large arm 16, a small arm 19 (rotating) rotatably mounted on the small arm base 18, and a swinging base 20 mounted at the end of the small arm. The sandblasting swing head 5 is mounted on the swinging base 20 via a swinging shaft and can swing under the drive of the swinging base. In addition, the double-angled sandblasting guide tube 6 (rotating) mounted on the sandblasting swing head 5 via the swing head rotation shaft together constitute a specific six-axis structure, which improves its control accuracy.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
