A spraying structure 6 is provided at a position close to one side of the center of the rear inner wall of the protective shell 1. Two placing structures 8 are arranged horizontally side by side at a position close to one side of the center of the lower inner wall of the protective shell 1. A spraying pipe 7 is arranged inside the spraying moving structure 5. The protective shell 1 provides a closed working environment to protect operators and the environment from dust during the spraying process. The box door 2 allows operators to enter the interior of the protective shell 1 for equipment maintenance and inspection. The stabilizing block 3 and the frame 4 together constitute the installation platform for the spraying moving structure 5 and the spraying structure 6, ensuring the stability and accuracy of the equipment.

The spraying structure 6 includes a slideway 601, a spraying box 602, and a suction pump 603, which are responsible for transporting the spraying material into the spraying pipe 7.

[0034] The spraying moving structure 5 includes a slide rail 501, two sliders 502, a chain 503, two gears 504, two motors 505, and two connecting plates 509. The slide rail 501 is arranged at the center of the front inner wall of the frame 4. The two sliders 502 are connected inside the slide rail 501. The two connecting plates 509 are respectively arranged at positions close to the upper part of the centers of the rear end faces of the two sliders 502. The two motors 505 are respectively arranged at positions close to both sides of the center of the rear end face of the frame 4. The two gears 504 are respectively arranged at positions close to both sides of the center of the interior of the frame 4. The output ends of the two motors 505 penetrate the rear end face of the frame 4 and lead to the interior of the frame 4, and the ends are respectively fixedly connected to the rear end faces of the two gears 504. The chain 503 is sleeved on the outer side walls of the two gears 504.

[0035] Through the combination of the slide rail 501 and the slider 502, the horizontal movement of the spraying pipe 7 on the inner wall of the steel pipe pile is realized. When the motor 505 rotates, the chain 503 is driven by the gear 504. Through the rotation of the chain 503, the slider 502 is driven to move along the slide rail 501, realizing the horizontal movement of the spraying pipe 7. Through the precise control of the motor 505 and the gear 504, the precise movement of the spraying pipe 7 on the inner wall of the steel pipe pile can be realized, ensuring the uniformity and consistency of spraying. The chain 503 meshes with the two gears 504 respectively, providing precise movement control to ensure the precise movement of the spraying pipe 7 along the inner wall of the steel pipe pile, thereby realizing a uniform spraying effect. The two sliders 502 are slidably connected inside the slide rail 501. The sliding connection of the slider 502 in the slide rail 501 ensures the stable movement of the spraying pipe 7, reducing the decline in spraying quality caused by vibration or instability.

[0036] On one side near the center of the outer sidewall of the spraying pipe 7, a plurality of spray nozzles 507 are arranged in a circular pattern. On the outer sidewall of the spraying pipe 7 on one side of the spray nozzles 507, a rotator 508 is provided. On the upper and lower end faces of the spraying pipe 7 at one side near the center inside the frame 4, a gripper 506 is provided. The spraying pipe 7 is one of the core components of the spraying device. It is responsible for evenly spraying spraying materials such as powder or liquid onto the inner wall of the steel pipe pile. The spray nozzles 507 are responsible for spraying the spraying materials onto the inner wall of the steel pipe pile. The function of the rotator 508 is to rotate the spraying pipe 7 during the spraying process to ensure that the spraying materials can evenly cover the entire inner wall of the steel pipe pile. The gripper 506 is used to fix the position of the spraying pipe 7 to prevent it from shifting during the spraying process, achieving all-round and uniform spraying of the inner wall of the steel pipe pile and ensuring the coverage and uniformity of the spraying materials.

[0037] The spraying structure 6 includes a slideway 601, a spraying box 602, and a suction pump 603. The slideway 601 is arranged at the center of the upper end face of the frame 4 and at one side near the center of the rear inner wall of the protective shell 1. The suction pump 603 is arranged at the output end of the spraying box 602. The output end of the suction pump 603 penetrates the upper end face of the slideway 601 and leads to the inside of the frame 4, and the end is fixedly connected to one end of the spraying pipe 7. The spraying box 602 is used to store the spraying materials and, through the suction pump 603, to suck out the spraying materials from the spraying box 602. When the suction pump 603 works, it sucks out the spraying materials from the spraying box 602 and transports them to the spraying pipe 7 through the slideway 601, thus realizing the transportation and spraying of the spraying materials.

[0038] The placing structure 8 includes a placing platform 801, an elastic layer 802, and a wear-resistant layer 803. The placing platform 801 is arranged on the lower inner wall of the protective shell 1. The elastic layer 802 is arranged on the upper end face of the placing platform 801. The placing platform 801 provides a stable supporting surface for the steel pipe pile. The function of the elastic layer 802 is to absorb the impact and vibration generated when the steel pipe pile is placed, reducing damage to the steel pipe pile. The wear-resistant layer 803 is used to improve the wear resistance and service life of the placing platform 801. The elastic layer 802 is made of rubber. The rubber elastic layer 802 can significantly reduce the possible damage to the steel pipe pile during the placement and removal processes and extend the service life of the steel pipe pile.

[0039] Working principle: After the user opens the box door 2 and places the steel pipe pile on the placement platform 801, the placement platform 801 provides a stable support surface for the steel pipe pile. The elastic layer 802 functions to absorb the impact and vibration generated when the steel pipe pile is placed, reducing damage to the steel pipe pile. The wear-resistant layer 803 is used to improve the wear resistance and service life of the placement platform 801. When the suction pump 603 works, it sucks the spraying material out of the spraying box 602 and transports it to the spraying pipe 7 through the slideway 601. When enough spraying material is transported inside the spraying pipe 7, the motor 505 is started. When the motor 505 rotates, the chain 503 is driven by the gear 504. Through the rotation of the chain 503, the slider 502 is driven to move along the slide rail 501, realizing the horizontal movement of the spraying pipe 7. Through the precise control of the motor 505 and the gear 504, the spraying pipe 7 is one of the core components of the spraying device. It is responsible for evenly spraying the spraying material such as powder or liquid onto the inner wall of the steel pipe pile. The nozzle 507 is responsible for spraying the spraying material onto the inner wall of the steel pipe pile. The function of the rotator 508 is to rotate the spraying pipe 7 during the spraying process to ensure that the spraying material can evenly cover the entire inner wall of the steel pipe pile. The clamp 506 is used to fix the position of the spraying pipe 7 to prevent it from shifting during the spraying process.
