Description

[0001] The disclosed embodiments relate to the technical field of detection equipment, and in particular to a detection device and method for the torque performance of a turnout connector anti-loosening device. Background Art

[0002] In order to meet the structural design and functional requirements, railway turnouts use a large number of bolted joints to achieve installation, laying, operation and maintenance adjustments. When the train passes through the railway turnout, the wheels form a long-term and high-frequency impact on the turnout structure, which can easily cause the bolts to loosen, reduce the axial tension of the bolted joints, and then affect the stability of the turnout components and the overall structure, endangering driving safety. Therefore, a corresponding bolted joint anti-loosening device must be set for the turnout track simulation to lock the bolted joint structure and ensure the safety and stability of the track and turnout structure.

The nut simulation part 300 is partially disposed in the anti-loosening device 10. The nut simulation part 300 is used to be fixedly connected with the anti-loosening device 10.

[0047] Please refer to Figure 5The locking member 400 includes: a second bolt head 401, a pin 402 and a screw 403 which are arranged in sequence. The diameter of the screw 403 is smaller than the diameter of the pin 402. The pin 402 is matched with the second through hole 301.

[0050] Based on the above embodiments, Figures 1 to 7 The specific structure and connection method of some components in this application are described in more detail.

[0051] First, the specific structure of the bolt simulation member 100 is described. Figure 2 , the first bolt head 101 is hexagonal, and the first groove 202 is hexagonal. Specifically, the first bolt head 101 is a large hexagon, so that it matches the fixed end of the torsion device. The size of the large hexagon is determined according to the inner size of the docking interface of the fixed end of the torsion device. Usually, the outer size of the large hexagonal head is the inner size of the docking interface-0.4mm (matching clearance), and the length is 45 to 50mm.

[0052] In addition, the end of the cylindrical rod 102 of the bolt simulation 100 is provided with an axial blind hole 1021, and the blind hole 1021 is provided with an M12-M20 internal thread with a depth of 12-15 mm. The diameter of the cylindrical rod 102 is consistent with the diameter of the bolt used in the actual working condition of the anti-loosening device 10.

[0053] Optionally, in some embodiments, the outer shape of the track simulation component 200 is a cuboid; the second groove 203 is a rectangular groove, which is used to clamp the anti-loosening device 10 to achieve a fixed connection therewith.

[0054] Next, the specific structure and connection relationship of the anti-loosening device 10 are described.

[0055] Please refer to Figure 1 and Figure 3 The anti-loosening device 10 includes: an anti-loosening base 11, a nut spacer 12 and an anti-loosening cap 13. One end of the nut spacer 12 is fixedly connected to the anti-loosening cap 13, and the other end of the nut spacer 12 is fixedly connected to the anti-loosening base 11. The anti-loosening base 11 and part of the nut spacer 12 are clamped in the second groove 203.

[0056] The anti-loosening process of the bolt connection pair simulated by the anti-loosening device 10 of the present application is as follows: the anti-loosening base 11, the nut spacer 12 and the anti-loosening cap 13 are all provided with through holes, the anti-loosening base 11 and the nut spacer 12 are sequentially sleeved on the cylindrical rod 102, and the anti-loosening base 11 and the nut spacer 12 are fixedly connected, and then the anti-loosening cap 13 is sleeved on the outside of the nut simulation part 300, and the anti-loosening cap 13 and the nut spacer 12 are fixedly connected, thereby playing the role of anti-loosening of the bolts and nuts respectively.

[0057] It can also be understood that the anti-loosening cap 13 is provided with a third through hole 131, which can be a linear circular hole, the nut simulation 300 is partially penetrated in the third through hole 131, and a washer 20 is provided between the nut simulation 300 and the nut spacer 12. The third through hole 131 can be a 12-pointed star through hole, which is used to engage the nut simulation 300 to prevent the nut simulation 300 from rotating.

[0058] In other embodiments, Figure 1 As shown, the third through hole 131 can be a stepped circular through hole, that is, the outer diameter of the third through hole 131 is smaller, the inner diameter is larger, and the inner side surface of the larger diameter is provided with teeth. At this time, after the nut simulation part 300 partially enters the anti-loosening cap 13, the nut simulation part 300 contacts the through hole with a smaller diameter, and there is a certain interval between the nut simulation part 300 and the through hole with a larger diameter. The interval is provided with a gear ring 14, and the outer surface of the gear ring 14 is provided with teeth. In one case, please refer to Figure 6 The gear ring 14 can be a separate component, the outer surface of which meshes with the teeth of the anti-loosening cap 13, and the inner surface of which is in the shape of a star and contacts with the nut simulation part 300 to prevent the nut simulation part 300 from rotating. In another case, please refer to Figure 7The gear ring 14 and the nut simulation member 300 are integrally formed, that is, the gear ring 14 is provided on the outer side surface of the end of the nut simulation member 300, and the nut simulation member 300 is engaged with the anti-loosening cap 13 by using the gear ring 14 provided thereon.

[0059] The following is an illustration of the dimensions of some structures in the above embodiments.

[0060] Please refer to Figure 3 The shape of the track simulation part 200 is a cuboid with a thickness of 35 mm and a length and width of 150 mm. The first through hole 201 of the track simulation part 200 is the diameter of the cylindrical rod 102 of the bolt simulation part 100 + 0.4 mm (fit clearance). The shape of the first groove 202 is hexagonal, with a depth of 15 to 20 mm. The inner dimension of the first groove 202 is the outer dimension of the first bolt head 101 (large hexagonal head) + 0.4 mm (fit clearance), and is used to connect and fix with the large hexagonal head of the bolt simulation part 100. The second groove 203 is a rectangular groove, and the depth, length and width are based on the fixing of the anti-loosening device 10.

[0061] Please refer to Figure 4 The outer dimensions of the nut simulation 300 are consistent with the outer dimensions of the hexagonal nut used in the actual working condition of the anti-loosening device 10. The diameter of the second through hole 301 is the outer dimensions of the hexagonal nut used in the actual working condition of the anti-loosening device 10 + 0.4mm (fit clearance), and the length of the nut simulation 300 is 35~40mm.

[0062] Please refer to Figure 5 The screw rod 403 of the locking member 400 is provided with an external thread matching the internal thread of the blind hole 1021. The diameter of the pin rod 402 is the external dimension of the hexagonal nut used in the actual working condition of the anti-loosening device 10 -0.4mm (fit clearance), and the length is the sum of the length of the nut simulation member 300 and the thickness of the washer 20. The second bolt head 401 is M24~M30, and is a hexagonal shape with a length of 10mm~20mm.

[0071] Optionally, in some embodiments, a torque value determination condition is preset, and the collected torque value is tested for compliance with the determination condition to determine whether the torque performance of the anti-loosening device 10 is qualified.

[0072] The torque value during the test can be collected by the sensor and then transmitted to the computer detection software. The torque and time curve is displayed on the software interface. When the torque-time curve shows a sudden change, the test process ends, and the corresponding torque displayed is the detection torque. The torque value judgment condition is set in the software, and the compliance of the test result with the judgment condition is automatically judged, and whether it is qualified is directly displayed on the software interface.

[0073] In the present application, a counterclockwise rotating torsional force is applied to the nut simulation member 300 to measure the torque. The torsional angular velocity may be 1° / min, and the torsional angular velocity is tested with a steady load.

[0074] During the detection process, the present application fully considers the system integrity of the turnout connector anti-loosening device 10, which is more in line with actual working conditions; the detection device of the present application has a simple structure and is easy to operate.

The test is carried out with a stable loading at a torsion angle speed of 1° / min. The torque value is collected and transmitted to the computer detection software through the sensor. The software interface displays the torque and time curve. When the torque-time curve has a sudden change (after the sudden change, the torque value suddenly decreases, indicating that part of the structure of the anti-loosening device 10 is broken, and the test is over), the test process ends, and the corresponding displayed torque is the detection torque. The test results are shown in Table 1.

[0076] In this test, the judgment condition is that the maximum torque value detected is not less than 500 N·m. According to Table 1, the torque performance of the anti-loosening device 10 tested in this test is qualified.
