Description

Technical Field

[0001] The utility model relates to the technical field of wet spraying manipulators, in particular to a wet spraying manipulator conveying and swinging mechanism with simple structure, high connection strength, stable turning and high sealing performance. Background Art

[0002] As we all know, concrete spraying robots are widely used in construction. They use compressed air or other power sources to transport a precisely proportioned mixture through a pipe and spray it at high speed onto the surface where it solidifies, forming a concrete support layer. Shotcrete technology is simple, cost-effective, and widely applicable, making it a vital tool in various construction applications.

[0003] Currently, the mechanism for controlling the rotation of the spray head in an existing concrete spraying robot is a rotary swing mechanism. The rotary swing mechanism includes a primary cylinder, a secondary cylinder, and a conveying swing mechanism. The primary cylinder is mounted on the extension arm of the mobile robot, and the secondary cylinder is connected to the output shaft of the primary cylinder. The output shaft of the secondary cylinder is connected to the conveying swing mechanism. The primary cylinder drives the secondary cylinder and the conveying swing mechanism to rotate together, and the secondary cylinder drives the conveying swing mechanism to rotate. The conveying swing mechanism includes a swing motor, a swing mounting frame, and a conveying pipe. The swing mounting frame is connected to the output shaft of the secondary cylinder. The swing motor is fixed to the swing mounting frame. The output shaft of the swing motor is fixedly connected to the conveying pipe. Since the output shaft of the swing motor is exposed and the entire working environment of the wet spraying robot is dusty, dust may enter the output shaft of the swing motor, resulting in unstable flipping. In addition, since the material being transported in the conveying pipe may pause, the conveying pipe will vibrate. The gravity of the conveying pipe is completely supported on the output shaft of the swing motor, causing the output shaft of the swing motor to be subjected to shaking force and medium gravity, resulting in a reduced service life of the output shaft of the swing motor, unstable flipping, and reduced connection strength. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies in the prior art and to provide a wet spraying manipulator conveying swing mechanism with simple structure, high connection strength, stable flipping and high sealing performance.
