Description

Technical Field

[0001] This utility model relates to the field of pipe grinding technology, and in particular to a tooling for internal inspection and grinding of pipes. Background Technology

[0002] Steel pipelines are widely used in many fields such as oil and natural gas transportation and urban pipeline network construction due to their significant advantages such as safety, low consumption and high efficiency. In the process of laying long-distance transportation pipelines, pipe sections need to be connected into a whole through welding. Due to the welding characteristics, the weld area between pipe sections is prone to various defects such as porosity, slag inclusion, and weld beads. These defects not only affect the aesthetics of the pipeline, but may also become stress concentration points, reducing the structural strength and service life of the pipeline. Therefore, it is necessary to carry out fine grinding and painting treatment at the weld to ensure pipeline quality and operational safety.

[0003] Traditional pipe interior grinding methods are mainly manual, requiring workers to hold grinding tools and go deep into the pipe to grind the inner wall section by section by manually rotating the grinding head. Although this method could meet basic grinding needs in early pipeline construction, its limitations have become increasingly apparent as the scale of projects expands and quality requirements increase. Manual grinding is inefficient, and for long-distance, large-diameter pipelines, the construction cycle is long and the labor cost is high. At the same time, the grinding quality is highly dependent on the experience and operational stability of the workers, making it difficult to ensure the uniformity and consistency of grinding in the weld area.

[0004] However, the metal dust generated during manual polishing can not only enter workers' bodies through the respiratory tract, potentially causing occupational diseases such as pneumoconiosis with long-term exposure, but also suspend inside the pipes, causing visual interference and forcing workers to frequently stop work to clean or adjust their operating posture, further reducing work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where manual entry into pipes for grinding not only causes physical harm to workers, but also affects visibility due to flying dust and reduces grinding efficiency. Therefore, this invention proposes a tooling for inspecting and grinding inside pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tooling for inspecting and grinding the inside of a pipe includes a fixed pipe and an angle grinder bracket, which is fixedly sleeved on the fixed pipe. An endoscope lens is installed inside the fixed pipe, and a cable is electrically connected to the endoscope lens. The end of the cable away from the endoscope lens passes through the fixed pipe and is electrically connected to a display screen. A guide wheel is installed on the fixed pipe, and the fixed pipe is provided with an adjusting component to support the guide wheel. A dust suction hood is provided on the fixed pipe.

[0008] For adjusting the telescopic reach of the guide wheel and the angle of the angle grinder and endoscope lens, preferably, the adjusting component includes an end joint bearing fixedly sleeved on a fixed tube, a positioning frame fixedly sleeved on the outer ring of the end joint bearing, and electric telescopic rods fixedly connected to the four corners of the positioning frame, with the telescopic ends of the electric telescopic rods fixedly connected to the guide wheel.

[0009] For positioning the endoscope lens, preferably, one end of the fixing tube is threaded with a sealing cap, and the endoscope lens is inserted into the sealing cap.

[0010] To facilitate connection between the vacuum hood and an external vacuum cleaner, preferably, a vacuum tube is fixedly installed inside the fixed tube, with one end of the vacuum tube passing through the fixed tube and fixedly connected to the vacuum hood.

[0011] To improve the anti-slip performance of the fixed tube, preferably, an anti-slip sleeve is fixedly fitted on the fixed tube, and the anti-slip sleeve is made of rubber.

[0012] To improve the dust adsorption effect, preferably, the dust hood is duckbill shaped, and the air inlet of the dust hood faces the shooting direction of the endoscope lens.

[0013] Compared with the prior art, this utility model provides a tooling for inspecting and grinding the inside of pipes, which has the following beneficial effects:

[0014] 1. The tooling for inspecting and grinding the inside of the pipe has an adjustable component. The operator can hold the free end of the fixed pipe and rotate it to adjust the angle of the angle grinder and endoscope lens. This facilitates the inspection of the inside of the pipe and also allows for uniform grinding of the inner wall of the pipe, thereby improving work efficiency.

[0015] 2. The tooling for inspecting and grinding inside the pipe is equipped with a suction pipe, which facilitates the connection between the suction hood and an external vacuum cleaner, thereby improving the quality of dust removal during pipe grinding.

[0016] 3. The tooling for inspecting and grinding inside the pipeline is equipped with a dust suction hood. The duckbill-shaped design narrows the air outlet to form a flat airflow channel, causing the airflow to form a high-speed jet at the outlet. According to the principles of fluid mechanics, the jet will entrain the surrounding air to form a negative pressure zone, which significantly enhances the adsorption capacity of smoke and dust.

[0017] All parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model uses an endoscope lens and a display screen to facilitate workers to inspect the inside of pipes. At the same time, the guide wheel can be extended and retracted using an adjusting component, so that the grinding fixture can adapt to the inner walls of pipes of different specifications. Furthermore, by connecting an external vacuum cleaner to the dust hood, the dust generated during grinding can be absorbed, improving the image quality of the endoscope lens.

[0027] Example:

[0028] Reference Figures 1-6A tooling for inspecting and grinding the inside of a pipe includes a fixed pipe 1 and an angle grinder bracket 2, which is fixedly fitted onto the fixed pipe 1. The angle grinder bracket 2 consists of two metal clamps, one for fitting onto the fixed pipe 1 and the other for fixing the angle grinder. An endoscope lens 3 is installed inside the fixed pipe 1, and a cable 4 is electrically connected to the endoscope lens 3. The end of the cable 4 away from the endoscope lens 3 passes through the fixed pipe 1 and is electrically connected to a display screen 5. The endoscope lens 3 and the display screen 5 are P40 handheld endoscopes with 8mm dual lenses and a 2-meter inspection cable. Available in 5-meter and 10-meter lengths, this portable tubular endoscope features a high-definition dual-lens design. One end of the fixed tube 1 is threaded with a sealing cap 9, and the endoscope lens 3 is inserted into the sealing cap 9. Four guide wheels 6 are mounted on the fixed tube 1. The fixed tube 1 is equipped with an adjustable component to support the guide wheels 6. The fixed tube 1 is also equipped with a dust suction hood 8, which is duckbill-shaped and has its air intake facing the shooting direction of the endoscope lens 3. A dust suction tube 10 is fixedly installed inside the fixed tube 1, with one end of the dust suction tube 10 passing through the fixed tube 1 and fixedly connected to the dust suction hood 8.

[0029] Specifically, the endoscope lens 3 and the display screen 5 work together to facilitate the inspection of the inside of the pipe by the staff. At the same time, the guide wheel 6 can be extended and retracted by the adjustment component so that the grinding fixture can adapt to the inner wall of pipes of different specifications. Furthermore, by connecting the external vacuum cleaner to the dust hood 8, the dust generated during grinding can be absorbed, thereby improving the image quality of the endoscope lens 3.

[0030] The adjusting component includes an end joint bearing 7, which is fixedly sleeved on the fixed tube 1. The outer ring of the end joint bearing 7 is fixedly sleeved with a positioning frame 71. Each of the four corners of the positioning frame 71 is fixedly connected to an electric telescopic rod 72. The telescopic end of the electric telescopic rod 72 is fixedly connected to the guide wheel 6.

[0031] Specifically, by setting an adjustment component, the operator can hold the free end of the fixed tube 1 and rotate it to adjust the angle of the angle grinder and the endoscope lens 3, which facilitates the inspection of the inside of the pipe and can also uniformly grind the inner wall of the pipe, thereby improving work efficiency.

[0032] A rubber anti-slip sleeve 11 is fixedly fitted on the fixed tube 1.

[0033] Specifically, the anti-slip sleeve 11 made of rubber can improve the anti-slip performance of the fixed tube 1, thereby making it easier for the operator to adjust the angle of the angle grinder.

[0034] Working principle: When inspecting the inside of the pipeline, the operator uses an external control switch to activate the electric telescopic rod 72. The telescopic end of the electric telescopic rod 72 drives the guide wheel 6 to the designated position. The operator then inserts the guide wheel 6 into the inner wall of the pipeline, allowing it to move while conforming to the inner wall. During this movement, the operator uses the endoscope lens 3 and the display screen 5 to inspect the inside of the pipeline. When it is necessary to grind the inner wall of the pipeline, the operator uses an external control switch to activate the angle grinder and adjusts the angle of the angle grinder by rotating the fixed tube 1, thus enabling all-around grinding of the inner wall of the pipeline.

[0035] During the polishing process, the staff connects the vacuum hose 10 to an external vacuum cleaner and starts the vacuum cleaner. At this time, the vacuum hood 8 sucks the dust generated during polishing into the vacuum cleaner, which can improve the imaging quality of the endoscope lens 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
