Description

[0002] Special equipment is widely used in many fields such as petrochemical, aviation, medical, mining, industry, etc. For example, in the petrochemical industry, special equipment such as reactors, steam generators, distillation towers, etc. are widely used in oil refining and chemical processing; in the aviation industry, special equipment such as machine tools, testing equipment, unit test benches, etc. are widely used in aircraft manufacturing and airport facility maintenance. Special equipment refers to equipment that poses a greater risk to personal and property safety, including some pressure-bearing equipment, such as pressure pipes, pressure vessels, etc., among which pressure pipes are tubular equipment that uses a certain pressure to transport gas or liquid.

[0003] In the process of using special equipment, it is necessary to apply suitable pressure pipelines. In order to determine the sealing performance of the pressure pipeline, the corresponding detection device is often required to detect the sealing performance of the pipeline, and judge the actual sealing performance of the pressure pipeline according to the test results to ensure that it can have better safety effects when put into use. However, traditional pressure detection equipment has the problem of low detection efficiency. At the same time, the pipeline cannot be classified according to the test results during the detection process. After the detection is completed, it is not convenient for operators to quickly confirm the specific crack location of the unqualified pipeline, which affects the subsequent efficiency of handling the specific unqualified situations of the unqualified pipeline, and the use effect is poor.

[0010] As a preferred technical solution of the present invention, the standard parts unloading assembly includes a pneumatic telescopic cylinder, which is fixedly arranged at the telescopic end of the first electric unloading rod, a piston block is slidably arranged in the pneumatic telescopic cylinder, one side of the piston block is fixedly connected to the piston column, a memory rebound part is sleeved on the piston column in the pneumatic telescopic cylinder, and the end of the piston column outside the pneumatic telescopic cylinder is fixedly connected to the unloading head.

[0011] As a preferred technical solution of the present invention, the air inlet end of the pneumatic telescopic cylinder is fixedly connected to the air transmission tube, the air inlet end of the air transmission tube is connected to the air outlet end of the air guide block, the top of the air guide block is fixedly connected to the air pressure detector, and the display panel of the air pressure detector corresponds to the image collector.

[0012] As a preferred technical solution of the present invention, the non-standard parts unloading assembly includes a push rod fixedly arranged at the telescopic end of the second electric unloading rod, a sensor device is arranged at one end of the push rod, and a signal output end of the sensor device corresponds to the image collector.

[0013] As a preferred technical solution of the present invention, the air pump assembly includes a pressurized air box fixedly arranged on one side of the enclosure, a telescopic air guide tube is arranged at the air outlet end of the pressurized air box, the air outlet end of the telescopic air guide tube is connected to the air inlet end of the inflation nozzle, and a telescopic air guide tube is arranged between the sealing nozzle and the air guide block.

[0014] As a preferred technical solution of the present invention, the pushing assembly includes a mounting block fixedly arranged on the side wall of the enclosure, one side of the mounting block is fixedly connected to an electric telescopic column, the telescopic end of the electric telescopic column is fixedly connected to a driving arm, and a fixing ring is fixedly sleeved on the sealing nozzle and the inflation nozzle, and the fixing ring is fixedly connected to the end of the driving arm.

[0015] As a preferred technical solution of the present invention, the liquid supply detection assembly includes a mounting arm fixedly arranged on the side wall of the enclosure, the mounting arm is fixedly connected to an electric push rod close to the loading tray, the telescopic end of the electric push rod is fixedly connected to an arc plate, the inner side of the arc plate is fixedly connected to a detection strip, and the detection strip is immersed in detection liquid.

[0016] The present invention has the following advantages: when in use, the operator places the end of the pipe to be inspected in the loading groove on the loading plate, and then drives the limit column to achieve fixed limit of the pipe under the action of the telescopic part, and then starts the driving motor to drive the loading plate to rotate. During the rotation, the arc plate is driven to move under the action of the electric push rod, and the detection strip on the arc plate will contact the outer wall of the pipe. Then, under the action of the electric telescopic column, the driving arm drives the air guide nozzle and the sealing nozzle on the fixed ring to achieve sealing of the two ends of the pipe. Then, under the action of the pressurized gas filling box, carbon dioxide gas with a certain pressure value is filled into the inside of the pipe. If the pipe is not sealed well and a leak occurs, the carbon dioxide gas will overflow from the leaking position of the pipe. At this time, since there is a detection liquid on the detection strip, the detection liquid will penetrate into the crack position of the pipe, and the carbon dioxide will mix with the detection liquid. At this time, the detection liquid will change color. At the same time, under the action of the air pressure, the gas will also enter the gas guide block from the sealing nozzle. Then it enters the pneumatic telescopic cylinder through the air guide block, and the piston block in the pneumatic telescopic cylinder will drive the piston column to extend and then drive the unloading head to move closer to one side of the loading tray. In this process, since the amount of pressurized inflation is fixed, if the pipeline leaks, the movement amplitude of the unloading head at one end of the pneumatic telescopic cylinder is different, and the pressure in the pneumatic telescopic cylinder is the largest when there is no leakage, and the movement amplitude of the unloading head is also the largest at this time. At this time, when the driving motor drives the loading tray to rotate intermittently, if the pipeline does not leak, the first electric unloading rod can drive the unloading head at one end of the pneumatic telescopic cylinder to contact the pipeline and unload the pipeline. If the pipeline leaks, the unloading head cannot move to the position corresponding to the contact with the pipeline. Therefore, when the loading tray rotates to the position on the side of the second electric unloading rod, the second electric unloading rod will drive the pushing rod to contact the pipeline. After the sensor on the pushing rod contacts the pipeline, it is squeezed and sends a signal to control the image collector to collect. At the same time, the pushing rod pushes the unqualified pipeline to the screening and recycling box;

[0017] In the above process, the device realizes the classification and recycling of pipelines, and can mark the position of pipeline cracks at the same time. Under the action of the air pressure detector, the specific pressure value of each pipeline can be recorded, and all are recorded on the corresponding display screen. At the same time, under the action of the image collector, each time an unqualified pipeline is detected, the unqualified pressure value of the leaking pipeline can be imaged, which is convenient for the operator to carry out targeted treatment of the pipeline later, greatly improving the convenience of subsequent processing of the pipeline, making the detection results more diverse, the detection efficiency higher, and the use effect better.

[0038] Example 3, please refer to Figure 1-Figure 8 The actual application scenario of the device is to use it in the operation of sealing detection of some special equipment. The operator places the end of the pipe to be detected in the loading groove 28 on the loading tray 10, and then drives the limit column 29 to achieve fixed limit of the pipe under the action of the telescopic member 31, and then starts the driving motor 12 to drive the loading tray 10 to rotate. During the rotation process, the arc plate 5 is driven to move under the action of the electric push rod 4. The detection strip 6 on the arc plate 5 will contact the outer wall of the pipe, and then the air guide nozzle and the sealing nozzle 17 on the fixed ring 36 are driven by the driving arm 22 under the action of the electric telescopic column 21 to achieve sealing of both ends of the pipe, and then pressurize the Under the action of the inflation box 23, carbon dioxide gas with a certain pressure value is filled into the inside of the pipeline. If the pipeline is not sealed well and a leak occurs, the carbon dioxide gas will overflow from the leaking position of the pipeline. At this time, since there is a detection liquid on the detection strip 6, the detection liquid will penetrate into the crack position of the pipeline, and the carbon dioxide will mix with the detection liquid. At this time, the detection liquid will change color. At the same time, under the action of air pressure, the gas will also enter the air guide block 39 from the sealing nozzle 17, and then enter the pneumatic telescopic cylinder 14 through the air guide block 39. The piston block 32 in the pneumatic telescopic cylinder 14 will drive the piston column 34 to extend and then drive the unloading head 16 to move closer to the side of the loading tray 10. In this process, Since the amount of pressurized inflation is fixed, if the pipeline leaks, the movement amplitude of the discharge head 16 at one end of the pneumatic telescopic cylinder 14 is different, and the pressure in the pneumatic telescopic cylinder 14 is the largest when there is no leakage, and the movement amplitude of the discharge head 16 is also the largest at this time. At this time, when the driving motor 12 drives the loading tray 10 to rotate intermittently, if the pipeline does not leak, the first electric discharge rod 13 can drive the discharge head 16 at one end of the pneumatic telescopic cylinder 14 to contact the pipeline and unload the pipeline. If the pipeline leaks, the discharge head 16 cannot move to the position corresponding to the contact with the pipeline. Therefore, when the loading tray 10 rotates to the side position of the second electric discharge rod 25, the second electric discharge rod 25 is used to discharge the material. The material rod 25 will drive the push rod 26 to contact the pipeline. After the sensor device 9 on the push rod 26 contacts the pipeline, it will be squeezed and send out a signal to control the image collector 18 to collect. At the same time, the push rod 26 will push the unqualified pipeline to the screening and recycling box 24. In the above process, the device realizes the classification and recycling of pipelines, and can mark the crack position of the pipeline. Under the action of the air pressure detector 27, the specific pressure value of each pipeline can be recorded, and all are recorded on the corresponding display screen. At the same time, under the action of the image collector 18, each time an unqualified pipeline is detected, the unqualified pressure value of the leaking pipeline can be imaged.
