Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe inspection, and in particular to a rotary all-round defect inspection device for seamless steel pipes. Background Technology

[0002] Seamless steel pipe is a type of steel with a hollow cross-section and no seams around its perimeter. It is manufactured by hot working methods such as piercing and hot rolling or cold working methods such as cold rolling and cold drawing. Defect detection of seamless steel pipe is an important part of ensuring its quality and performance, including chemical composition analysis, visual inspection, dimensional inspection, bending and ovality detection, and non-destructive testing.

[0003] The existing Chinese utility model patent with application number CN201821288227.0 relates to a seamless steel pipe internal and external defect detection device, including a rubber roller, a rotating platform, an endoscope, an area array camera, a bracket, a lead screw, a guide rail and a mounting plate, etc. It can detect defects on the inner and outer walls of seamless steel pipes, and is stable in movement, easy to operate, comprehensive in detection and highly reliable.

[0004] However, the above-mentioned device does not have the ability to operate continuously in actual use. In particular, the process of transporting steel pipes on the equipment requires the use of external equipment for hoisting, which reduces the operating efficiency of the equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a seamless steel pipe rotary all-round defect detection device that uses a conveying device to transport steel pipes, connects to the steel pipe production line, facilitates steel pipe transportation, improves equipment inspection efficiency, uses a transverse movement device to inspect the entire surface of the steel pipe, uses a protective device to prevent the steel pipe from colliding with the equipment during transportation and inspection, and uses a rotating device to drive the steel pipe to rotate in conjunction with the transverse movement device to inspect the entire steel pipe, thus improving the practicality of the device.

[0006] This utility model discloses a rotary omnidirectional defect detection device for seamless steel pipes, comprising a conveying device, a transverse moving device, a protective device, and a rotating device. The transverse moving device is mounted on the conveying device, the protective device is mounted on the conveying device, and the rotating device is mounted on the conveying device. The conveying device transports the steel pipes and connects to the steel pipe production line, facilitating pipe transportation and improving equipment detection efficiency. The transverse moving device performs overall surface detection on the steel pipes. The protective device prevents damage to the equipment from collisions during transport and detection. The rotating device drives the steel pipes to rotate in conjunction with the transverse moving device to perform overall detection of the steel pipes, thus improving the practicality of the device.

[0007] Preferably, the conveying device includes a frame, conveying rollers, limiting grooves, and motors. Multiple sets of conveying rollers are horizontally mounted on the frame, and limiting grooves are provided in the middle of the conveying rollers. Multiple sets of motors are mounted on the side of the frame, and the output ends of the multiple sets of motors are respectively connected to the multiple sets of conveying rollers on the frame. When the motors are turned on, power is transmitted to the conveying rollers to drive them to rotate, which assists in the transportation process of the steel pipes, enhances the continuous inspection capability of the equipment, reduces the time lost in the steel pipe handling process, and improves the inspection efficiency of the equipment. The limiting grooves on the conveying rollers limit the steel pipes, which facilitates inspection in conjunction with the transverse movement device, thus improving the practicality of the device.

[0008] Preferably, the transverse movement device includes a transverse movement chamber, a geared motor, a transverse movement platform, a lead screw, and transverse movement limiting rods. The transverse movement chamber is installed on the right side of the upper end face of the frame, and the geared motor is installed on the left end face of the transverse movement chamber. The lead screw and two sets of transverse movement limiting rods are horizontally installed inside the transverse movement chamber. The transverse movement platform is connected to the lead screw through a nut. Both sets of transverse movement limiting rods pass through the transverse movement platform. A strip hole is provided on the upper end face of the transverse movement chamber to communicate with the interior of the transverse movement chamber. When the geared motor is turned on, power is transmitted to the lead screw to drive the lead screw to rotate. The rotating lead screw transmits power to the transverse movement platform through the nut, causing the transverse movement platform to move laterally inside the transverse movement chamber, thereby driving the detection equipment to detect the surface of the pipe. The transverse movement process of the transverse movement platform is limited by the two sets of transverse movement limiting rods, reducing the impact of the transverse movement platform's own vibration on the detection process, and improving the stability and practicality of the device.

[0009] Preferably, the device also includes an L-shaped bracket, a first electric cylinder, a detection platform, and a camera module. The L-shaped bracket is connected to the upper surface of the transverse platform. The upper part of the L-shaped bracket extends through the strip hole on the transverse chamber to the upper side of the limiting groove. The first electric cylinder is installed on the upper surface of the L-shaped bracket. The detection platform is connected to the moving end of the first electric cylinder. The camera module is installed on the lower surface of the detection platform. By controlling the extension of the first electric cylinder, the working height of the detection platform can be adjusted, enabling the device to adapt to steel pipes of different diameters. Combined with the camera module, the device can detect the surface of the steel pipe, thus improving its adaptability and practicality.

[0010] Preferably, the protective device includes a protective plate, a pressure switch, a spring, and a pressing rod. A set of circular holes is provided at the front and rear of the right end face of the testing platform, and a set of pressing rods is provided at the front and rear of the left end face of the protective plate. The two sets of pressing rods are inserted into the two sets of circular holes on the testing platform. A pressure switch is provided on the left end face of each circular hole, and the pressure switch is connected to the pressing rods via the spring. The protective plate provides protection for the main body of the testing platform, preventing the steel pipe from directly colliding with the testing platform. In the event of a collision, the steel pipe presses against the protective plate, causing the pressing rods to move to the left, transmitting pressure to the pressure switch via the spring. When the pressure switch detects that the pressure exceeds a preset value, it controls the equipment to stop operating, preventing collisions and improving the practicality of the device.

[0011] Preferably, the rotating device includes a second electric cylinder, a lifting platform, support rollers, a drive motor, lifting limit rods, and lifting limit sleeves. Multiple sets of second electric cylinders are installed on the bottom surface of the frame, located below the gaps between the multiple sets of conveying rollers. A lifting platform is connected to the moving end of each second electric cylinder. Support rollers are installed at the front and rear of the lifting platform. Lifting limit rods are installed at the front and rear of the lower end of the lifting platform. Lifting limit sleeves are installed at the front and rear of each set of second electric cylinders on the upper surface of the frame. The lifting limit rods can be inserted into the lifting limit sleeves. A set of drive motors is installed on the lifting platform of the second electric cylinder. The output end of the drive motors is connected to a set of support rollers. By controlling the extension of multiple sets of second electric cylinders, the two sets of support rollers on the lifting platform are driven to rise, thereby enabling the support rollers to lift the steel pipe and separate it from the conveying rollers. Then, the drive motor is turned on to transmit power to the support rollers connected to it, causing the support rollers to rotate. The rotating support rollers drive the steel pipe to rotate, thereby cooperating with the transverse movement device to complete the surface inspection of the steel pipe. The lifting and lowering process of the lifting platform is limited by the lifting limit rod and the lifting limit sleeve, which improves the practicality of the device.
