Description

Technical Field

[0001] This utility model relates to the field of cladding flaw detection technology, and more specifically, to a camera mechanism for flaw detection of the cladding quality of the inner wall of pipes. Background Technology

[0002] A cladding device is a piece of equipment used for surface cladding technology. It typically uses a high-energy-density heat source, such as a laser, plasma arc, or electron beam, to heat metal or alloy powder to a molten state and then clad it onto the surface of the workpiece to form a cladding layer with specific properties.

[0003] During the cladding process on the inner wall of pipes, the cladding quality directly affects the durability and safety of the pipes. The quality of the cladding is influenced by the process and the method used to process the cladding head. Therefore, product quality inspection is necessary after processing. Existing equipment is not convenient for 360-degree all-around inspection of the inner wall of the clad pipe, and low inspection quality will affect subsequent product use. In view of this, we propose a flaw detection camera mechanism for the cladding quality of pipe inner walls. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a flaw detection camera mechanism for the inner wall cladding quality of pipes, so as to solve the technical problems of the current flaw detection mechanism being inconvenient to conduct blind spot detection and having low detection quality.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a flaw detection camera mechanism for the inner wall cladding quality of pipes, including an assembly frame, a rotating frame, and a flaw detection cylinder. The assembly frame is installed at the front end of the drive frame of the inspection line. A drive disk is rotatably installed at the outer end of the assembly frame. The rotating frame is fixedly installed on the drive disk. A guide rail assembly is provided on the outer side of the rotating frame, and an adjustment frame is slidably installed at the lower end of the guide rail assembly. An assembly base is embedded at the front end of the adjustment frame. The flaw detection cylinder is inserted into the inner opening of the assembly base. A cylinder is provided at the upper end of the flaw detection cylinder. A lifting cylinder is slidably installed in the bottom opening of the flaw detection cylinder, and a flaw detection head is provided at the bottom of the lifting cylinder.

[0006] In use, this invention involves inserting the assembly frame and the front-end rotating frame into the pipe port via a drive frame. The flaw detector's camera is then activated to inspect the cladding joint inside the pipe. The guide rail assembly is activated, causing the adjustment frame to rise and fall, which in turn adjusts the height of the flaw detector, allowing the camera to focus. Then, a motor is started, rotating the drive disc, which in turn rotates the rotating frame. This structure allows the flaw detector's camera to rotate 360 ​​degrees, achieving comprehensive, blind-spot-free inspection and taking high-definition photos of the pipe's inner wall. Furthermore, image analysis technology can be used to monitor and evaluate the cladding quality in real time, ensuring product quality. During the use of the device, the flaw detector head needs to be inserted into the pipe. The existing device requires the height of the flaw detector head to complete the camera focusing. Improper operation can easily damage the camera at the flaw detector head. By using a protective cover to externally protect the flaw detector head, the camera can perform external inspection through the flaw detector head. The flaw detector head reduces the camera's field of view. The lifting cylinder can be lowered by starting the cylinder, and the latch can be changed from the first latch to the second latch. Pressing down on the outer side of the flaw detector head can open the protective cover, which is installed with a torsion spring, to a certain angle, thereby increasing the field of view and improving the efficiency of inspection.

[0007] Preferably, a motor is fixedly installed on the inner side of the assembly frame, and the output shaft of the motor is connected to the drive disk.

[0008] Preferably, the bottom of the mounting base is provided with a protective cover, and there are four protective covers in total, which are arranged in a circular array. The protective covers are rotatably mounted on the outside of the bottom opening of the mounting base by a torsion spring hinge.

[0009] Preferably, the protective cover has a probe opening at the connection point, the four protective covers form a ring-shaped protective mechanism, and the ring-shaped protective mechanism is adapted to the probe head, the probe opening corresponding to the camera of the probe head.

[0010] Preferably, a buckle is embedded in the upper front side of the lifting cylinder, and a first slot and a second slot are provided at the upper end of the flaw detection cylinder, and the buckle is adapted to the first slot and the second slot.

[0011] Preferably, a compression spring is sleeved and installed in the middle of the lifting cylinder, and the upper and lower ends of the compression spring are respectively fixed to the lifting cylinder and the flaw detection cylinder.

[0012] Preferably, a cylinder is embedded in the upper end of the flaw detection cylinder, and the lower end of the cylinder is connected to the upper end of the lifting cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs an assembly frame. During use, the assembly frame and the front rotating frame are inserted into the pipe port via a drive frame. The camera of the flaw detector head is activated to detect flaws in the cladding port inside the pipe. The guide rail assembly is activated to raise and lower the adjustment frame, which in turn adjusts the height of the flaw detector head to achieve camera focusing. Then, the motor is activated to drive the drive plate to rotate, which in turn drives the rotating frame to rotate. Through the above structure, the flaw detector head camera rotates 360 degrees, achieving a flawless inspection and taking high-definition pictures of the inner wall of the pipe. Subsequently, image analysis technology can be used to achieve real-time monitoring and evaluation of the cladding quality, ensuring product quality.

[0015] 2. This utility model also incorporates a protective cover. During the use of the device, the flaw detector head needs to be inserted into the pipe. Existing devices require height adjustment of the flaw detector head to focus the camera. Improper operation can easily damage the camera at the flaw detector head. The protective cover provides external protection for the flaw detector head, allowing the camera to perform external inspections through the flaw. The flaw reduces the camera's field of view. The lifting cylinder can be lowered by starting a cylinder, and the latch can be changed from the first latch to the second latch. Pressing down on the outer side of the flaw detector head allows the protective cover, which is installed with a torsion spring, to open at a certain angle, increasing the field of view and improving inspection efficiency.
