Description

Technical Field

[0001] This utility model relates to the technical field of appearance inspection devices, specifically an appearance inspection device for special equipment. Background Technology

[0002] Special equipment refers to eight categories of equipment that involve life safety and are highly dangerous, including boilers, pressure vessels, pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities, and special motor vehicles for on-site use. Pressure cylinders belong to the pressure vessel category of special equipment and are mainly used for storing and transporting compressed or liquefied gases. They are characterized by mobility and refillability. Visual inspection equipment is required to assist in the visual inspection of pressure cylinders.

[0003] For example, the announcement number is CNU (named a non-destructive testing device for special equipment), which includes a base. Support plates are fixedly installed on both sides of the base. A drive pulley is rotatably connected to the top of each support plate. A transmission belt is fitted around the outside of the drive pulley. Brackets are fixedly installed on both sides of the middle of the base. A rotation detection component is installed inside the brackets. A mounting shell is fixedly installed on the top of the rotation detection component. An ultrasonic probe is installed on the bottom side of the mounting shell. A mounting groove is formed in the middle of the base, and a rotating platform is installed within the mounting groove. A built-in motor is installed inside the base near the support plates. The output of the built-in motor... A rotating rod is fixedly installed at one end of the shaft, and the rotating rod passes through the top of the support plate and is fixedly connected to the drive pulley. By starting the built-in motor, the drive pulley will rotate, which in turn will drive the rotation detection component to rotate through the transmission belt. The drive pulley will drive the driven pulley to rotate, which will cause the telescopic rods on both sides to rotate synchronously. This will cause the ultrasonic probe at the top of the telescopic rod to rotate around the special equipment for detection. At the same time, the servo motor will be started to drive the placement platform to rotate, which will cause the special equipment on the top of the placement platform to rotate. This allows for all-round detection of the special equipment, avoiding major accidents caused by putting it into use without detecting local damage or faults.

[0004] The aforementioned special equipment inspection equipment facilitates comprehensive inspection of special equipment through its adjustable mechanism. However, it cannot flip the equipment over during the inspection process, resulting in the bottom surface of the equipment not being effectively inspected, which affects the inspection results. Therefore, we provide a visual inspection device for special equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a device for the appearance inspection of special equipment, in order to solve the problem mentioned in the background art that the existing special equipment inspection equipment facilitates the all-round inspection of special equipment through the set movable adjustment mechanism, but cannot flip the special equipment during the inspection process, resulting in the bottom part of the special equipment not being effectively inspected, thus affecting the inspection effect of special equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for visual inspection of special equipment, comprising a device frame, an inspection cavity provided at the center of the device frame, two support rollers provided inside the inspection cavity, and a pressure gas cylinder being provided in contact and support between the two support rollers;

[0007] Also includes:

[0008] The movable guide rail is positioned directly above the detection cavity, and a threaded screw is installed inside the movable guide rail. A screw slider is movably mounted on the screw, and a hanging rod is welded to the lower end of the screw slider. A visual inspection camera is fixed to the lower end of the hanging rod by screws.

[0009] A hollow bottom groove is located at the bottom center of the device frame. The hollow bottom groove is connected to the interior of the detection cavity. A support platform is provided below the hollow bottom groove, and an electric push rod is fixed to the upper end of the support platform by screws.

[0010] The top material arc plate is located below the pressure gas cylinder and inside the detection cavity. The piston rod of the electric push rod passes through the hollow bottom groove and is welded to the top material arc plate.

[0011] Preferably, a support plate is provided on one side of the detection cavity. The support plate and the device frame are an integral structure. A computer is fixedly mounted on the front end of the support plate by screws. A data cable is provided between the output end of the visual inspection camera and the input end of the computer.

[0012] Preferably, the screw thread is provided with horizontal guide rods on both sides, and both horizontal guide rods are integral with the movable guide rail. The screw slider is guided and connected to the movable guide rail through the horizontal guide rods.

[0013] Preferably, a lead screw motor is fixed to one end of the movable guide rail by screws, and the output shaft of the lead screw motor is connected to the threaded lead screw inside the movable guide rail via a coupling.

[0014] Preferably, one end of the device frame is fixed with two drive motors by screws, and the output shafts of the two drive motors are respectively connected to the rotating shafts of the two supporting rollers through couplings.

[0015] Preferably, two mounting rods are provided on each of the two outer walls of the movable guide rail, and the two ends of the four mounting rods are welded to the movable guide rail and the device frame, respectively.

[0016] Preferably, four connecting rods are provided between the bearing platform and the four supporting base frames, and the two ends of the connecting rods are welded to the bearing platform and the supporting base frames respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention places the pressure cylinder to be tested inside the testing cavity and supports it with two supporting rollers. Two drive motors then rotate the rollers in the same direction, causing the cylinder to rotate in contact with them. This allows for comprehensive visual inspection of the cylinder's outer walls, preventing the bottom from being missed. After inspection, an electric push rod raises the top plate, simultaneously lifting the cylinder for easy retrieval from the testing cavity. This overcomes the problem of existing special equipment testing equipment, which, while allowing for comprehensive inspection through adjustable mechanisms, cannot flip the equipment during testing, resulting in ineffective inspection of the bottom surface and affecting the testing results.
