Description

Technical Field

[0001] This utility model relates to the technical field of composite pipe processing equipment, and in particular to a large-diameter composite pipe testing and repair equipment. Background Technology

[0002] Large-diameter composite pipes are widely used in many fields such as water supply and drainage, oil and gas transportation, and chemical industry. During their production and manufacturing process, various defects can easily occur due to factors such as the quality of raw materials, processing technology, and equipment precision. The outer surface of the pipe may have obvious flaws such as scratches, pits, and protrusions. If these defects are not detected and dealt with in time, they will seriously reduce the service life of the composite pipe and may even cause safety accidents during use, resulting in huge economic losses and safety risks.

[0003] The existing composite pipe testing and repair equipment still has the following problems:

[0004] 1. Some composite pipe testing and repair equipment uses non-replaceable devices to fix composite pipes, making it impossible to fix and install large-diameter composite pipes of different specifications. This results in poor versatility and adaptability, failing to meet diverse production needs and increasing testing costs.

[0005] 2. Traditional composite pipe inspection and repair rely heavily on manual observation and manual repair. This method is not only inefficient but also has low inspection accuracy. It is almost impossible to accurately identify minor defects. In addition, the manual repair process is very easy to cause secondary damage to the pipe and has low repair efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a large-diameter composite pipe inspection and repair device. This addresses the problem that existing composite pipe inspection and repair devices typically use non-replaceable fixing devices, making it impossible to fix and install large-diameter composite pipes of different specifications. This results in poor versatility and adaptability, failing to meet diverse production needs, increasing inspection costs, and relying heavily on manual observation and repair. This method is not only inefficient but also has low inspection accuracy, making it almost impossible to accurately identify minute defects. Furthermore, manual repair can easily cause secondary damage to the pipe material, and the repair efficiency is low.

[0007] To achieve the above objectives, a large-diameter composite pipe testing and repair device is provided, including a workbench. Slots are provided on both sides of the workbench, and slide rods are fixedly installed in the slots. Two sliding blocks are slidably installed on the slide rods. Two fixing plates are fixedly installed at the upper middle part of the two sliding blocks, and a connecting plate is fixedly installed between the two sliding blocks.

[0008] A cylinder two is fixedly installed on the upper end of one of the fixed plates, and a flange is fixedly installed on the extended end of the cylinder two. A servo motor one is fixedly installed on the upper end of the other fixed plate, and the output end of the servo motor one is also connected to a flange through a coupling. A fixing block is threadedly installed on one side of each flange, and bolts are threadedly fixed to both the flange and the fixing block.

[0009] According to the large-diameter composite pipe testing and repair equipment, a cylinder three is fixedly installed at one end of the bottom of the workbench, and a connecting block is fixedly installed at the extended end of the cylinder three.

[0010] According to the large-diameter composite pipe testing and repair equipment, an opening is provided in one of the slots, the opening is adapted to a connecting block, and the upper end of the connecting block is fixedly installed on the bottom of a sliding block.

[0011] According to the large-diameter composite pipe testing and repair equipment, a second support frame is fixedly installed on both sides of the middle part of the workbench, and an LED light is provided at the bottom of the second support frame.

[0012] According to the large-diameter composite pipe testing and repair equipment, a camera is provided on one side of the bottom of the second support frame, and the camera is located to the left of the LED light.

[0013] According to the large-diameter composite pipe testing and repair equipment, a support frame is fixedly installed on both sides of the end of the workbench, and a cylinder is fixedly installed on the upper end of the support frame.

[0014] According to the large-diameter composite pipe testing and repair equipment, the extension end of the cylinder one passes through the support frame one and is fixedly installed downwards in a mounting box. The mounting box is fixedly installed with a servo motor two, and the output end of the servo motor two is connected to a grinding wheel through a coupling.

[0015] According to the aforementioned large-diameter composite pipe testing and repair equipment, support legs are fixedly installed at the four corners of the bottom of the workbench.

[0016] The above-mentioned solution has the following beneficial effects:

[0017] 1. This patent, by setting up cylinder two, flange, bolt, fixing block and servo motor one, allows for the replacement of the device for fixing the composite pipe during use. Cylinder two can drive a fixing block to move, thereby satisfying the need to fix and install large-diameter composite pipes of different specifications and sizes. This significantly improves versatility and adaptability, thereby meeting diverse production needs and reducing testing costs.

A flange 11 is connected, and a fixing block 7 is threaded on one side of the flange 11. Both the flange 11 and the fixing block 7 are threaded with bolts 12. In use, first select a matching fixing block 7 according to the inner diameter of the composite pipe, and then fix the fixing block 7 to the flange 11 respectively by using bolts 12. Then, according to the length of the composite pipe, first start the cylinder 10 to drive the fixing block 7 fixed on the flange 11 at the extension end of the cylinder 10 to move, thereby fixing the composite pipe in the middle of the two fixing blocks 7. Then start the servo motor 13 to drive the flange 11, the fixing block 7 and the composite pipe to rotate.

[0030] A cylinder 17 is fixedly installed at one end of the bottom of the workbench 1. A connecting block 18 is fixedly installed at the extended end of the cylinder 17. An opening 19 is provided in a slot 16. The opening 19 is adapted to the connecting block 18. The upper end of the connecting block 18 is fixedly installed at the bottom of a sliding block 8.

[0032] Working principle: When putting a large-diameter composite pipe inspection and repair equipment into use, first select a suitable fixing block 7 according to the inner diameter of the composite pipe, and then fix the fixing block 7 to the flange 11 respectively using bolts 12. Then, according to the length of the composite pipe, first start the cylinder 10, which drives the fixing block 7 fixedly installed on the flange 11 at the extension end of the cylinder 10 to move, thereby fixing the composite pipe in the middle of the two fixing blocks 7. Then start the servo motor 13, which drives the flange 11, the fixing block 7 and the composite pipe to rotate. The cylinder 17 drives the connecting block 18, which is fixedly installed at the extension end, to move. This causes the two sliding blocks 8, which are fixedly connected by the connecting plate 14, to move. When the block passes the bottom of the support frame 6, the camera 21 detects the composite tube. When a protrusion is detected in the composite tube, and the protrusion moves to the bottom of the support frame 4, the servo motor 23 is started to drive the grinding wheel 22 to rotate. Then, the cylinder 5 is started to drive the mounting box 3, the servo motor 23, and the grinding wheel 22 to move downward, thereby trimming the protrusion on the composite tube.
