Description

TECHNICAL FIELD

[0001] The utility model belongs to steel pipe testing technical field, and specifically is a kind of steel pipe length measurement with weighing sample pipe. BACKGROUND

[0002] In industrial production and quality detection process, the weighing and length measurement of steel pipe are important links to ensure that product meets standard requirements.The steel pipe length measurement with weighing sample pipe is mainly used for calibration and comparison of single weighing length measurement equipment to ensure measurement accuracy.Because steel pipe can be affected by factors such as material deviation, processing error during production, transportation and use, its actual quality data needs to be obtained by weighing.Meanwhile, accurate measurement of the quality of sample pipe helps to optimize the accuracy of length measurement equipment, improve the reliability of measurement data and ensure the accuracy of subsequent detection work.

[0003] However, the complete steel pipe length measurement with weighing sample pipe is usually long, generally about ten meters, and there are many difficulties in direct overall weighing or calibration.Firstly, due to the long length and large weight of steel pipe, overall weighing can easily cause unstable data due to gravity shift, affecting measurement accuracy.Secondly, during calibration, complete sample pipe is difficult to accurately measure on standard equipment, and error can also be caused by equipment limitation or inconvenient operation due to its length. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims to provide a kind of steel pipe length measurement with weighing sample pipe to solve at least one aspect of the problems and defects proposed in the above background technology.

[0005] A kind of steel pipe length measurement with weighing sample pipe is provided, comprising several pipe subassemblies, several pipe subassemblies are connected to each other, the pipe subassembly includes internal connecting pipe and external connecting pipe, adjacent internal connecting pipe and external connecting pipe are mutually clamped, and the internal connecting pipe and external connecting pipe are connected at the fixed ring.

[0006] Further, a plurality of clamping portions are provided on the outer side of the internal connecting pipe in the circumferential direction, the clamping portions can be clamped into the corresponding clamping grooves inside the external connecting pipe, so that the two are fixed together, the clamping type connection structure can provide stable connection, and is convenient for disassembly and reassembly, so that the sample pipe is more stable, accurate, easy to disassemble and reassemble when segmented connection, thereby improving the accuracy of length measurement and operation convenience.

[0007] Further, the inner part of the external connecting pipe is provided with a plurality of clamping grooves in the circumferential direction, and a plurality of clamping parts are clamped in the plurality of clamping grooves, and the clamping parts are embedded in the clamping grooves when inserted into the external connecting pipe, thereby achieving stable mechanical connection. The connecting structure can effectively prevent loosening caused by vibration or external force during use, thereby improving the connection reliability. Different lengths of sample pipes can be quickly disassembled or assembled according to requirements, so as to adapt to segmented weighing measurement, improve measurement accuracy, solve the problems of difficult weighing and calibration of long sample pipes, and improve the convenience and measurement accuracy of use.

[0008] Further, the clamping part is a rectangular protruding structure, and the clamping part adopts a rectangular protruding structure, that is, the outer shape is a regular rectangular protrusion, instead of a circular or beveled buckle. The rectangular structure can enhance the stability of contact and reduce the risk of loosening. Compared with other shapes, the rectangular protruding structure can be more firmly embedded in the clamping groove, thereby avoiding loosening caused by vibration or external force.

[0009] Further, the upper part of the fixing ring is provided with a plurality of mounting holes, and a jacking bolt is arranged in each of the plurality of mounting holes. The clamping force provided by the jacking bolt can effectively limit the axial displacement between the internal connecting pipe and the external connecting pipe, thereby improving the measurement accuracy. Uniformly distributed stress of the plurality of mounting holes enables the plurality of jacking bolts to uniformly act on the surface of the connecting pipe, thereby avoiding single-point stress concentration, improving the structural stability and durability, and facilitating installation and disassembly. Compared with welding or permanent fixing mode, the jacking bolt connection can be quickly installed or disassembled, thereby improving the use flexibility of the sample pipe.

[0010] Further, the upper part of the jacking bolt is provided with an arc top block, and the arc top block of the end part of the jacking bolt is directly in contact with the external connecting pipe when the jacking bolt is tightened. The contact area of the arc top block is larger than that of the end part of the bolt, so that the clamping force can be uniformly distributed, thereby avoiding deformation or damage of the pipe wall caused by single-point stress.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] The plurality of pipe subassemblies are used for segmented weighing, and then the weights of the parts are accumulated to obtain the accurate mass of the whole sample pipe. The segmented measurement can effectively improve the measurement accuracy, avoid the weight error or inconvenient weighing caused by the too long whole sample pipe, and ensure the accuracy of the measurement data by pre-calibrating the sample pipe according to the standard before measurement. The measurement accuracy of the single-branch weighing and length measuring equipment is improved. The segmented measurement not only can improve the measurement accuracy and avoid the error caused by the too long whole sample pipe, but also can facilitate transportation, storage and use, and improve the convenience of operation.

[0022] Please refer to Figures 1-4As shown, the utility model discloses a kind of steel pipe length measurement with weighing sample tube, including several sub-pipe assemblies 100, several sub-pipe assemblies 100 are connected with each other, several sub-pipe assemblies 100 all include internal connecting pipe 101 and external connecting pipe 102, adjacent internal connecting pipe 101 and external connecting pipe 102 are mutually clamped, and fixed ring 200 is arranged at the junction of internal connecting pipe 101 and external connecting pipe 102;

[0023] Sub-pipe assembly 100 is composed of internal connecting pipe 101 and external connecting pipe 102.

[0024] Adjacent internal connecting pipe 101 and external connecting pipe 102 are clamped, forming a stable connection structure, and fixed ring 200 is used to further enhance the stability of the connection to ensure that there is no looseness or deviation during segmentation and weighing. Since the length of the complete sample tube is usually about ten meters, direct weighing or calibration is difficult, so multiple sub-pipe assemblies 100 are used for segmented weighing, and then the weights of each part are added up to obtain the accurate mass of the entire sample tube. Segmental measurement can effectively improve the measurement accuracy and avoid the weight error or weighing inconvenience caused by the length of the whole sample tube. Before measurement, the sample tube can be pre-calibrated according to the standard to ensure the accuracy of the measurement data and avoid errors caused by the length of the whole sample tube. The measurement accuracy of the single weighing length measurement device can be improved, which can be split as needed for convenient transportation, storage and use, and to avoid inconvenience in operation.

[0025] In one embodiment, please refer to Figure 1 、 Figure 2 And Figure 4 As shown, the outer side of internal connecting pipe 101 is provided with a plurality of clamping portions 1011 in the circumferential direction, and the outer side of internal connecting pipe 101 is provided with a plurality of clamping portions 1011 in the circumferential direction. Clamping portion 1011 is used for stable clamping with external connecting pipe 102 to form a reliable connection structure. When internal connecting pipe 101 is inserted into the inside of external connecting pipe 102, clamping portion 1011 can be clamped into the corresponding clamping groove 1021 inside external connecting pipe 102, so that the two are fixed together, and the clamping type connection structure can provide stable connection, while facilitating disassembly and reassembly, so that the sample tube is more stable, accurate and easy to disassemble when segmented, thereby improving the accuracy and operation convenience of length measurement and weighing.

[0026] In one embodiment, please refer to Figure 1 、 Figure 2 And Figure 3As shown, the inner part of the external connecting pipe 102 is provided with a plurality of clamping grooves 1021 in the circumferential direction, and a plurality of clamping parts 1011 are clamped in the plurality of clamping grooves 1021. When the clamping part 1011 is inserted into the external connecting pipe 102, it will be embedded in the clamping groove 1021 to achieve stable mechanical connection. The connection structure can effectively prevent loosening caused by vibration or external force during use, and improve the connection reliability. Different lengths of sample pipes can be quickly disassembled or assembled according to the needs to adapt to segmented weighing measurement, improve the measurement accuracy, solve the problem of long sample pipe not easy to weigh and calibrate, and improve the convenience and measurement accuracy of use.

[0027] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the clamping part 1011 is a rectangular protruding structure. The clamping part 1011 adopts a rectangular protruding structure, that is, its shape is a regular rectangular protrusion, rather than a circular or beveled buckle. The clamping groove 1021 of the external connecting pipe 102 is designed as a matching rectangular groove to ensure that the clamping part 1011 can be stably embedded. The rectangular protruding structure provides a larger contact area. Compared with other shapes such as circular or chamfered buckles, the rectangular structure can enhance the contact stability and reduce the risk of loosening. Compared with other shapes, the rectangular protruding structure can be more firmly embedded in the clamping groove 1021 to avoid loosening caused by vibration or external force.

The fixing ring 200 is firmly combined with the internal connecting pipe 101 and the external connecting pipe 102 through the action of the tightening bolts 300 to prevent loosening. The clamping force provided by the tightening bolts 300 can effectively limit the axial displacement between the internal connecting pipe 101 and the external connecting pipe 102 during weighing or measurement to improve the measurement accuracy. The uniform distribution of stress of the plurality of mounting holes 2001 enables the plurality of tightening bolts 300 to uniformly act on the surface of the connecting pipe, avoiding single-point stress concentration and improving the structural stability and durability. Compared with welding or permanent fixing methods, the use of tightening bolts 300 for connection can quickly install or disassemble, improving the flexibility of the sample pipe.

[0029] In one embodiment, as shown in Figure 1 and Figure 2 Figure 1 Figure 2As shown, the upper part of the jacking bolt 300 is provided with an arc top block 400, and the upper part of the jacking bolt 300 is provided with the arc top block 400, that is, the end of the jacking bolt 300 is not directly in contact with the external connecting pipe 102, but forces through the arc top block 400. When the jacking bolt 300 is tightened, the arc top block 400 at the end thereof is directly in contact with the external connecting pipe 102; the contact area of the arc top block 400 is greater than that of the bolt end, can uniformly distribute the clamping force, avoids the deformation or damage of the pipe wall caused by single-point force, and the arc of the arc top block 400 is matched with the arc of the external connecting pipe 102.
