[0022] The following specific embodiments illustrate the implementation of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosed content.

[0023] The present application provides a kind of pipe material meter weight wall thickness automatic detection device, the following preferred embodiments of pipe material meter weight wall thickness automatic detection device are described.

[0024] Example one

[0025] Pipe detection equipment is used for the measurement of pipe weight, length and wall thickness. In the pipe production cycle, it is necessary to regularly patrol the finished pipe, according to the pipe data of the patrol, the qualified rate of the pipe can be reflected, and the production can be adjusted according to the data, which is of great significance. The commonly used inspection method at present is manual detection and record, and the data record is usually recorded manually on paper, which is low in efficiency and inconvenient for data statistics and analysis. The device for pipe detection in the prior art is mostly manually transported, measured and recorded, which improves the efficiency of manual measurement and data recording of each pipe, but the degree of automation is not high, and the data recording and statistics are inconvenient. The present application proposes a pipe material meter weight wall thickness automatic detection device with high degree of automation, which can be set on the process program after the pipe production equipment, saving the manual transportation process, realizing the measurement of pipe meter weight and wall thickness, recording data at the same time, improving the production efficiency, facilitating the adjustment of pipe production, and reducing the labor cost.

[0026] As shown in the accompanying drawings Figure 1As shown, in this embodiment, the automatic pipe weight / wall thickness detection device uses a tilting frame 100 as a whole, including three support bases. The support bases are equipped with connecting brackets for connecting other components. The tilting frame 100 has two tilting rods 101, which are L-shaped. The connecting brackets leave a gap for the tilting frame 100, allowing it to move up and down within the gap. The two tilting frames 100 face the same direction. A hydraulic cylinder 102 is connected to the bottom of the tilting frame 100, which is used to push the tilting frame 100 up and down. The device is positioned on the left side of the tilting frame 100. Roller assemblies 200 are connected to both ends on the right. The roller assemblies 200 are connected to the connecting bracket via a rotating shaft 503. The rotation axes of the two roller assemblies 200 are parallel and at the same height. Each rotating assembly has an arc-shaped recess 201. When the pipe is transported on the roller assembly 200, the arc-shaped recess 201 can keep the pipe centered and prevent the pipe from rubbing against the turning rack 100 or other components or falling off. The roller assembly 200 uses nylon rollers to avoid scratching or bumping the pipe. The rotation direction of the roller assembly 200 and the roller assembly 300 is the same.

[0027] A roller assembly 300 is provided between the two tilting frames 100. The roller assembly 300 is located at the midpoint of the length of the tilting frame 100. The roller assembly 300 consists of a traction belt 301, a built-in drive motor, and two rollers. The drive motor drives the rollers to rotate, so that the traction belt 301 rotates around the two rollers. The height of the roller assembly 300 should be higher than the height of the two roller assemblies 200. The pipe is transported on the first roller assembly 200. When the front section touches the roller assembly 300, it is driven forward by the friction of the traction belt 301 and continues to be transported. If the height of the roller assembly 300 is lower than the height of the roller assembly 200, this function cannot be achieved.

[0028] A weighing component 400 is set at each end of the roller assembly 300. Each weighing component 400 is located between the roller assembly 300 and the adjacent tipping bar 101. Each weighing component 400 is connected to a hydraulic cylinder 102. The hydraulic cylinder 102 can lift the weighing component 400. When both weighing components 400 are lifted at the same time, the pipe on the roller assembly 300 can be lifted and weighed. Each weighing component 400 is provided with an arc-shaped recess 201 to prevent the pipe from falling off during weighing. At the end of the flipping rack 100, i.e. the end of the flipping rack 100 in the pipe transport direction, a ranging component 500 is provided. The ranging component 500 includes a rotary motor 502 and a laser rangefinder 501. The laser rangefinder 501 is connected to the rotary motor 502 through a rotating shaft 503. The rotary motor 502 can drive the laser rangefinder 501 to rotate and measure the wall thickness of the pipe. When measuring the wall thickness of the pipe, the laser rangefinder 501 performs laser ranging through two sensors, one of which is located inside the pipe and the other is located outside the pipe.

[0029] The embodiment also includes an information processing and recording assembly 600, which is connected to each hydraulic cylinder 102 on the turnover rack 100, each roller assembly 200 and 300, the weighing assembly 400, and the distance measuring assembly 500. During the pipe meter weight and wall thickness measurement process, the information processing and recording assembly 600 controls the roller assemblies 200 and 300 to transport the pipe to the measurement position, controls the weighing assembly 400 to lift the weighing, and controls the distance measuring assembly 500 to measure the pipe wall thickness. Finally, the data is recorded.

[0030] Taking the recorded data after pipe production as an example, the operation steps of the pipe meter weight and wall thickness automatic detection device in the embodiment are as follows: After the pipe is produced by the production machine, it is directly transported to the roller assembly 200, transported to the roller assembly 300 through the roller assembly 200, and pulled by the roller assembly 300 to the end roller assembly 200. When the front end of the pipe extends between the two sensors of the laser range finder 501, the information processing and recording assembly 600 controls the roller assembly 300 to stop rotating, controls the hydraulic cylinders 102 of the two weighing assemblies 400 to lift the weighing assemblies 400, and controls the two weighing assemblies 400 to lift the pipe and measure the weight. After the lifting of the weighing assembly 400 is completed, the information processing and recording assembly 600 controls the rotation of the motor 502, and the laser range finder 501 measures the wall thickness of the pipe. When the distance measuring assembly 500 completes the measurement, the information processing and control system controls the weighing assembly 400 to descend to the initial position, the pipe returns to the surface of the roller assembly 300, the information processing and control system controls the hydraulic cylinders 102 of the two turnover levers 101 to lift, pushes the pipe out, and the pipe is turned into the rack.

[0031] The pipe meter weight and wall thickness automatic detection device in the embodiment has a simpler structure than the pipe measurement device in the prior art, can be improved on the basis of the turnover rack 100, and further saves costs. It can measure the meter weight and wall thickness of the pipe, record the data, save labor costs, and be arranged after the process flow of the pipe production device or used for pipe inspection, and is flexible to use.

[0032] Embodiment Two

Figure 1, including the turnover frame 100, the overall frame of the turnover frame 100 adopts a split steel structure design, mainly composed of H-shaped steel connection; the turnover frame 100 is provided with two turnover rods 101, the two turnover rods are connected respectively to one hydraulic cylinder 102, the hydraulic cylinder 102 is fixedly connected to the turnover frame 100, the turnover rod 101 is L-shaped and is arranged obliquely, relies on the extension and contraction movement of the hydraulic cylinder 102, drives the turnover rod 101 to move up and down, thereby pushing the pipe out; the turnover frame 100 is further provided with a roller assembly 200 and a roller assembly 300, the roller assembly 200 is provided with a circular arc recess 201 on the surface, the circular arc recess 201 ensures that the pipe is not easy to fall off from the roller assembly 200 during transportation, two roller assemblies 200 are arranged at both ends of the turnover frame 100 in the embodiment; the roller assembly 200 adopts a polyurethane rubber-coated roller, an R50mm circular arc recess 201 is processed on the surface; the roller assembly 300 is located at the middle position of the turnover frame 100, the roller assembly 300 includes a traction belt 301 responsible for driving the pipe, two rollers supporting the traction belt 301, a driving motor driving the two rollers to rotate, the driving motor adopts a 2.2kW servo motor drive, the two rollers adopt a synchronous transmission structure, an anti-skid pattern is arranged on the surface of the traction belt 301, further preventing the pipe from slipping, the installation height of the roller assembly 200 is lower than the installation height of the roller assembly 300 by 200mm, forming a natural slope.

[0034] The weighing assembly 400 is connected to the turnover rack 100 through the hydraulic cylinder 102, and has a round smooth recess 401 with a radius of 60 mm at the upper end, which prevents the pipe from sliding during the weighing process.

At the end of the pipe transportation direction, the turnover rack 100 is further connected to a distance measuring assembly 500, which comprises a laser range finder 501 and a rotary motor 502. The laser range finder 501 is connected to the rotary motor 502 through a rotating shaft 503, and has a U-shaped structure.
