[0023] Beneficial Effects

[0024] The present invention provides a compressive strength detection device and a detection method for high-speed railway track fastener processing.

[0025] Compared with the prior art, it has the following beneficial effects:

[0026] 1. Based on the compressive strength detection device and detection method for high-speed rail fastener processing, through the mutual cooperation between the placement plate mechanism, the hydraulic cylinder, the bearing plate mechanism, the extrusion plate mechanism and the servo motor, multiple high-speed rail fasteners to be detected are placed on the corresponding positions on the placement plate mechanism, and then the hydraulic cylinder is started to drive the bearing plate mechanism and the extrusion plate mechanism to move downward, and then the servo motor is started to drive the extrusion plate mechanism to rotate. During the rotation process of the extrusion plate mechanism, the bearing plate mechanism cooperates with the extrusion plate mechanism to achieve multiple repeated downward extrusion operations on multiple fasteners at the same time, that is, the compressive strength test of multiple fasteners can be carried out in a short time, thereby improving the overall detection efficiency.

[0027] 2. Based on the compressive strength detection device and detection method for high-speed railway track fastener processing, through the mutual cooperation between the bearing plate, the protrusion, the top plate and the lower pressure roller, when the lower pressure roller passes through the upper surface of the bearing plate and the upper surface of the protrusion alternately, when passing through the upper surface of the protrusion, the pressure applied to the fastener is large, and when passing through the upper surface of the bearing plate, the pressure applied to the fastener is small, thereby simulating the situation when the wheel at the bottom of the high-speed railway passes directly over the fastener on the track, the gravity of the wheel completely acts on the fastener, and the pressure generated on it is large, and when the wheel leaves the fastener, the gravity of the wheel partially acts on the fastener, and the pressure generated on it is relatively small, thereby simulating the dynamic force environment of the fastener during the actual running of the high-speed railway wheel on the track, so that the test results are closer to the performance of the fastener in actual use, and the accuracy of the test results is improved.

[0028] 3. Based on the compressive strength detection device and detection method for high-speed rail track fastener processing, through the mutual cooperation between the square rod, the third limit hole, the third bolt and the second scale, each third bolt can be pulled out in turn, and the horizontal height of each lower pressure roller can be adjusted within a certain range. The greater the distance the lower pressure roller is adjusted downward, the greater the pressure value generated on the bump when the lower pressure roller passes through the upper surface of the bump. By adjusting the downward distance of the lower pressure roller, the pressure value applied to the upper surface of the bump can be accurately controlled, that is, the pressure value applied to the fastener can be accurately controlled, so as to achieve the purpose of applying different test pressure values ​​to the top of the fastener and meet various detection needs.

[0029] 4. Based on the compressive strength detection device and detection method for high-speed railway track fastener processing, through the mutual cooperation between the protrusion, the first limiting hole and the second bolt, the second bolt is inserted into the first limiting hole at different heights in the protrusion, and the height of the top of the protrusion protruding from the upper surface of the carrier plate can be adjusted, that is, when the second bolt is inserted into the first limiting hole located at the bottom, the part of the top of the protrusion that can protrude from the upper surface of the carrier plate is at a maximum value, and conversely, the part of the top of the protrusion that can protrude from the upper surface of the carrier plate is at a minimum value, thereby achieving the effect of adjusting the top of the protrusion to protrude from the upper surface of the carrier plate at different heights. When the protrusion protrudes to the maximum value, the lower pressure roller passes through the upper surface of the protrusion and can apply greater pressure. Conversely, when the protrusion protrudes to the minimum value, the lower pressure roller passes through the upper surface of the protrusion and can apply less pressure, thereby achieving the purpose of applying different test pressures to the test fasteners.

The extrusion plate mechanism 6 includes a top plate 61. A plurality of square rods 62 are uniformly slidably penetrated in a circle on the top outer side of the top plate 61. A U-shaped plate 63 located below the top plate 61 is fixedly provided at the bottom of each square rod 62. A lower pressure roller 64 is rotatably provided in each U-shaped plate 63. A plurality of third limiting holes 65 are provided from top to bottom on the side away from each other of the plurality of square rods 62.

Each third bolt 66 is threadedly penetrated in the corresponding third limiting hole 65. A second scale 67 is provided on the surface of the side away from each other of the plurality of square rods 62. A rotating shaft 68 is fixedly penetrated in the middle of the top plate 61.The bottom of the rotating shaft 68 is rotatably connected to the top of the square column 57, and the top of the rotating shaft 68 is rotatably passed through the bottom of the placement box 10 and is fixedly connected to the output shaft of the servo motor 11.

[0056] Through the cooperation among the bearing plate 51, the protrusion 53, the top plate 61 and the lower pressure roller 64, when the lower pressure roller 64 passes through the upper surface of the bearing plate 51 and the upper surface of the protrusion 53 alternately, when passing through the upper surface of the protrusion 53, the pressure applied to the fastener is large, and when passing through the upper surface of the bearing plate 51, the pressure applied to the fastener is small, thereby simulating that when the wheel at the bottom of the high-speed rail passes directly above the fastener, the gravity of the wheel completely acts on the fastener, and the pressure on it is large, and when the wheel leaves the fastener, the gravity of the wheel partially acts on the fastener, The pressure is relatively small, simulating the dynamic force environment of the high-speed rail wheel on the fastener during actual driving, so that the test result is closer to the performance of the fastener in actual use, and the accuracy of the test result is improved.

The greater the distance the lower pressure roller 64 is adjusted downward, the greater the pressure value generated on the protrusion 53 when the lower pressure roller 64 passes through the upper surface of the protrusion 53. The larger the distance, the more accurately the pressure value applied to the upper surface of the protrusion 53 can be controlled by adjusting the downward movement distance of the lower pressure roller 64, that is, the accurately controlled pressure value applied to the fastener can be used to achieve the purpose of applying different test pressure values ​​to the top of the fastener, and meet various detection requirements.

When the protrusion 53 is in the position hole 54, the portion of the top of the protrusion 53 that can protrude from the upper surface of the carrier plate 51 is at a maximum value, otherwise the portion of the top of the protrusion 53 that can protrude from the upper surface of the carrier plate 51 is at a minimum value, thereby achieving the effect of adjusting the protrusion of the top of the protrusion 53 to different heights above the upper surface of the carrier plate 51. When the protrusion 53 protrudes to the maximum value, the lower pressure roller 64 passes through the upper surface of the protrusion 53 and can apply a greater pressure. Otherwise, when the protrusion 53 protrudes to the minimum value, the lower pressure roller 64 passes through the upper surface of the protrusion 53 and can apply a smaller pressure, thereby achieving the purpose of applying different test pressures to the test fasteners.

[0057] The embodiment of the present invention further provides a method for detecting the compressive strength of high-speed rail fasteners, using a device for detecting the compressive strength of high-speed rail fasteners. The specific method includes the following steps:

[0058] Step 1, open the transparent sealing door 12, pull the top plate assembly 34 upwards, and then place the high-speed rail track fastener to be tested in the placement seat 321, then place the square limit frame 323 on the top of the placement seat 321, and at the same time, the square limit frame 323 is located at the recessed position of the fastener, and the square limit frame 323 is locked on the top of the placement seat 321 by using the first bolt 324, and the position of the fastener is limited and locked at the same time, and then the pull on the top plate assembly 34 is released, and the top plate assembly 34 moves downward under the action of its own gravity, and the lower surface of the top plate assembly 34 contacts the top of the fastener directly below, observe the first scale 333 pointed to by the pointer plate 343 at this time, and record the initial horizontal position of the top plate assembly 34 at this time;

[0059] Step 2, then start the hydraulic cylinder 4, pull the bearing plate mechanism 5 and the squeezing plate mechanism 6 downward to the preset position, so that the bottom of the bearing plate 51 contacts the top of the plurality of top plate assemblies 34, and the bottom of the lower pressure roller 64 contacts the top of the bearing plate 51, then pull out the latch 59, and the bearing plate 51 is freely slidably sleeved on the outside of the square column 57, because the positions of the plurality of lower pressure rollers 64 and the plurality of protrusions 53 are arranged one by one, then start the servo motor 11, drive the rotating shaft 68 to rotate, and during the rotation of the rotating shaft 68, the top plate 61 is driven to rotate, and the plurality of lower pressure rollers 64 rotate accordingly, and during the rotation of the lower pressure roller 64, when passing through the upper surface of each protrusion 53, the bearing plate 51 is pressed downward as a whole, and the pressure is transmitted to the fastener through the top plate assembly 34, and the fastener below is squeezed, and the squeezing plate mechanism 6 rotates a set number of circles, and multiple squeezing of the fastener is completed in the process;

[0060] Step three, then start the hydraulic cylinder 4 again to push the bearing plate mechanism 5 and the squeezing plate mechanism 6 upwards, so that the squeezing plate mechanism 6 is in its original position. At this time, the top of the top plate assembly 34 is not affected by external pressure, and the lower surface contacts the top of the fastener directly below under the action of its own gravity. After the test is completed, the pointer plate 343 points to the first scale 333, and the horizontal position of the top plate assembly 34 at this time is recorded. The horizontal position of the top plate assembly 34 after the test is completed is compared with the initial horizontal position of the top plate assembly 34, and the range of the position change is observed, that is, the value can be adjusted according to the actual detection requirements. When the value exceeds the set range, for example, the horizontal position of the top plate assembly 34 after the test deviates from the initial horizontal position by more than three scales, the fastener to be tested is unqualified, otherwise it is qualified, thereby realizing the compressive strength test of the fastener.
