Description

Technical Field

[0001] The present invention relates to the technical field of strength detection equipment, and in particular to a device for detecting the compressive strength of a rail gauge baffle. Background Art

[0002] Rail gauge plates are essential fastening and adjustment components in railway track systems, maintaining the standard distance between rails and ensuring safe and stable train travel. During production, specialized stamping and shearing equipment is used to precisely cut and punch the plates. After production, to ensure quality across batches, product samples undergo strength testing. Furthermore, some rail gauge plates are injection molded, and these samples also require post-production strength testing to ensure they meet applicable standards. Currently, universal testing machines are used for testing, securing the plates with a fixture and applying pressure using a pneumatic cylinder. However, this method can only test a single part at a time, and the sample must be reloaded between each test. This is inefficient for batches of at least five parts. Furthermore, the limitation to single-part testing creates gaps in the processing of multiple parts, resulting in discontinuous operations.

[0003] Therefore, it is urgent to design a rail gauge baffle compressive strength testing device with continuous multi-workpiece testing function, aiming to solve the low efficiency problem existing in the existing testing technology, thereby improving the speed and reliability of the overall testing process. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a rail gauge baffle compressive strength testing device with a continuous multi-workpiece testing function.

Rack 2 is arranged relative to rack 1 on the same side so that the upper pressure plate and the lower pressure plate operate in relative directions.

[0007] Furthermore, it also includes a support plate, a through groove is opened on the lower roller frame, and a support plate is set on both sides of the through groove. A turntable rotates between the support plates on both sides, and a push plate is arranged circumferentially on the turntable for moving the rail baffle body to unload the material. A motor with an output end connected to the rotating end of the turntable is also installed on one side of the support plate.

[0008] Furthermore, it also includes a rotating rod, and a rotating rod is rotated on both sides of the upper roller frame. A torsion spring is arranged between the rotating rod and the outer wall of the upper roller frame.

[0010] Furthermore, it also includes contact terminals, and the top of the position adjustment plate is provided with contact terminals arranged at intervals.

[0011] Furthermore, the two card frames each have a wedge-shaped end on one side facing each other, and the bottom surface of the wedge-shaped end is flat.

[0012] Furthermore, the upper roller frame and the lower roller frame are inclined downward from the back to the front.

[0013] The present invention has the following advantages: by tilting the lower roller frame and the upper roller frame, continuous testing of multiple rail gauge baffles can be achieved in one operation, thereby greatly improving the testing efficiency; in addition, by combining the coordinated operation of the stabilizing component and the limiting component, the upper and lower pressure plates are used to ensure that the position of the rail baffle body is stable during the detection process, reducing manual intervention and improving the stability and accuracy of the testing process; and the design of the limiting component ensures that each baffle to be tested can be accurately positioned at the test position and remain stable throughout the test process, avoiding test errors caused by inaccurate positioning or loose fixation.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: A device for detecting the compressive strength of a rail gauge baffle, such as Figures 1-6 Shown, including: The rack 1 is provided with two, and a lower roller rack 2 and an upper roller rack 21 are obliquely arranged between the two racks 1. The wheels on the lower roller rack 2 and the upper roller rack 21 are relatively distributed up and down, and both show a trend of gradually tilting downward from the back to the front. The rotation of the wheel body itself is used to assist in pushing the rail baffle body 100, and the rail baffle body 100 can automatically move forward and feed with the help of gravity, thereby ensuring its stable forward movement and realizing the detection and transportation processing of multiple samples; Two cylinders 3 are respectively arranged on the front sides of the two frames 1, and the telescopic ends of both are arranged upward. A push rod 31 is provided on the telescopic end of each cylinder 3 for applying pressure to the rail stopper body 100. The push rod 31 has a built-in pressure sensor to monitor and transmit test data in real time. At the same time, considering that the rail stopper body 100 has a specific extended protrusion structure, the push rod 31 can accurately apply pressure and bend this part, which can effectively achieve the required compressive strength test. A stabilizing assembly 4 for stabilizing the detection position of the rail stopper body 100 includes mounting brackets 41 fixedly mounted on the two frames 1, an upper pressing plate 42 and a lower pressing plate 43 sliding between the two mounting brackets 41, and the upper pressing plate 42 and the lower pressing plate 43 cooperate to fix the detection position of the rail stopper body 100. Drive assemblies for driving the upper pressing plate 42 and the lower pressing plate 43 are provided on the mounting brackets 41, respectively, to ensure the automation of the operation of the two, making the operation of the device more consistent; The limit assembly 5 includes a contact frame 51 fixedly arranged between the lower front parts of the two mounting frames 41. The contact frame 51 is located below the lower pressure plate 43. The contact frame 51 has raised ends with a left-right symmetrical layout. The two raised ends have a downwardly inclined inclined surface on the side away from each other. A card frame 52 is symmetrically slidable on the left and right sides of the lower front part of the lower pressure plate 43. The two card frames 52 have wedge-shaped ends on the opposite sides. The bottom surface of the wedge-shaped end is flat, and the opposite sides of the two have wedge-shaped surfaces inclined downward. An elastic member 53 is provided between the card frame 52 and the inner wall of the lower pressure plate 43. In this embodiment, the elastic member 53 is a spring, which can provide the necessary elastic force for the reset movement of the card frame 52. A card frame 52 is also provided. There is an inclined block 54 that contacts and cooperates with the raised end on the same side. The inclined block 54 and the inclined surface of the corresponding raised end match each other to achieve smooth contact. A movable frame 55 passes through and slides in the middle of the front side of the bottom plate of the lower roller frame 2. The movable frame 55 can move up and down along the bottom plate of the lower roller frame 2. A stop block 56 is provided at the top of the movable frame 55 to limit the position of the rail baffle body 100. An elastic member 2 57 is provided between the stop block 56 and the bottom plate of the lower roller frame 2. In this embodiment, the elastic member 2 57 is a spring, which provides an elastic force for the reset movement of the movable frame 55 and the stop block 56. The bottom end of the movable frame 55 is provided with a contact block 58 that contacts and slides with the card frame 52. The left and right sides of the contact block 58 are provided with grooves for easy cooperation with the wedge surface of the card frame 52.

[0027] like Figure 3-Figure 5 As shown, the driving assembly includes driving motors 44 respectively arranged on the mounting frames 41, and the output ends of the driving motors 44 are connected to the driving gears 45 located in the corresponding mounting frames 41. Racks 1 421 meshing with the driving gears 45 on the same side are provided on both sides of the upper pressure plate 42, and racks 2 431 meshing with the driving gears 45 on the same side are provided on both sides of the lower pressure plate 43. The racks 2 431 and the racks 1 421 on the same side are arranged relative to each other, so that the upper pressure plate 42 and the lower pressure plate 43 operate in relative directions.

[0028] During use, the rail guard bodies 100 are placed one by one between the lower roller frame 2 and the upper roller frame 21. Due to the inclined configuration of the device, the rail guard bodies 100 move forward along the inclination. At this time, the stop block 56 is located in front of the gap between the lower roller frame 2 and the upper roller frame 21, and the upper and lower pressure plates 42 and 43 are in an open position. At the same time, the inclined block 54 contacts the raised end of the contact frame 51, keeping the two side frames 52 separated from each other and the elastic member 1 53 in a compressed state. As the rail baffle body 100 moves forward, it comes into contact with the stop block 56 and limits the movement of the rail baffle body 100 through the stop block 56, and then starts the drive motor 44 to drive the corresponding drive gear 45 to rotate. As the drive gear 45 rotates, the corresponding meshing rack 1 421 and rack 2 431 are driven to move, prompting the two to move closer to each other, and then drive the connected upper pressure plate 42 and lower pressure plate 43 to move closer to each other, and gradually contact the rail baffle body 100 to clamp and fix it. At the same time, as the lower pressure plate 43 moves upward, the card frame 52 is disengaged from the contact with the corresponding raised end of the contact frame 51, the inclined block 54 is released from the abutment with the corresponding raised end, and the elastic member 1 53 is reset accordingly. The card frames 52 on both sides are reset and move closer to each other. The pressing plate 43 moves synchronously until the wedge-shaped end of the card frame 52 comes into contact with the contact block 58. At this time, the lower pressing plate 43 has not yet come into contact with the rail stopper body 100. Until the wedge-shaped end of the card frame 52 is stuck in the corresponding groove of the contact block 58, the elastic member 1 53 is deformed accordingly. When the lower pressing plate 43 continues to move up a certain distance and contacts the rail stopper body 100 to achieve clamping, the wedge-shaped end of the card frame 52 will also fit the groove of the contact block 58 and move up a certain distance, thereby achieving the situation where the upper pressing plate 42, the lower pressing plate 43 and the stop block 56 jointly restrict the movement of the rail stopper body 100, thereby further stabilizing the detection position of the rail stopper body 100, and then starting the cylinder 3 on the corresponding side to drive the connected push rod 31 to move up, thereby applying pressure to the rail stopper body 100 for strength testing; After the detection is completed, the cylinder 3 is reset, the drive motor 44 is reversed, and the drive gear 45 drives the rack 1 421 and the rack 2 431 to move in the opposite direction through meshing, so that the upper pressure plate 42 and the lower pressure plate 43 are separated and reset. After the lower pressure plate 43 moves down a certain distance, the card frame 52 and its wedge-shaped end move down accordingly until the bottom plane of the wedge-shaped end of the card frame 52 contacts the contact block 58 and forms a resisting state, thereby synchronously pulling the contact block 58, the moving frame 55 and the resisting block 56 to move down synchronously, and the elastic member 2 57 is deformed accordingly. At this time, the rail baffle body 100 that has been tested is no longer restricted by the resisting block 56 and can continue to move forward. The rail baffle body 100 is discharged, and the subsequent rail baffle body 100 is gradually moved forward to replace it until the inclined block 54 contacts the raised end of the contact frame 51 again, and uses its own tilting tendency to make the card frames 52 on both sides move away from each other, and the elastic member 1 53 returns to the compressed state. At the same time, the card frame 52 is freed from the restriction of the corresponding contact block 58, and the elastic member 2 57 is reset. The contact block 58, the movable frame 55 and the stop block 56 move up synchronously, and the stop block 56 returns to its original position and limits the position of the rail baffle body 100 that has replaced it. This cycle is repeated until the rail baffle bodies 100 in the device are detected one by one.

[0029] Example 2: Based on Example 1, Figure 7 and Figure 8 As shown, it also includes a support plate 6, and a through groove 20 is opened in the front and rear directions on the bottom plate of the lower roller frame 2. A support plate 6 is fixedly provided on the left and right sides of the through groove 20. A turntable 62 is rotated between the support plates 6 on both sides, and a push plate 63 is arranged circumferentially on the turntable 62. The push plate 63 is used to push the rail baffle body 100 for automatic feeding. A motor 61 with an output end connected to the rotating end of the turntable 62 is also installed on one side of the support plate 6.

[0030] When the rail baffle body 100 that has been inspected is discharged and a new sample is needed to replace it, the motor 61 is started to drive the turntable 62 to rotate, and the rail baffle body 100 that needs to be replaced is pushed forward by the push plate 63 so that it can be quickly replaced to the vacant position at the inspection position, thereby achieving the effect of rapid material replacement.

[0031] like Figure 7 and Figure 9 As shown, it also includes a turning rod 7. Turning rods 7 are rotated on the left and right sides of the upper roller frame 21. Torsion springs 71 are provided between the turning rod 7 and the outer wall of the upper roller frame 21. A marking pen 72 is also provided on the turning rod 7. The marking pens 72 on both sides are different in color and can cope with different production batches of rail baffle bodies 100 for differentiated marking processing. The other side of the turning rod 7 is provided with a contact plate 73 that contacts and cooperates with the rail baffle body 100.

[0032] Since it is necessary to inspect rail baffle bodies 100 of different production batches during inspection, in view of this situation, when using the device, it is possible to reversely place and distinguish rail baffle bodies 100 according to different batches, that is, the extended protrusions of rail baffle bodies 100 of different batches are arranged relative to each other. As the rail baffle body 100 tilts forward, its extended protrusion will contact the contact plate 73, driving the corresponding rotating rod 7 to rotate, and the torsion spring 71 will deform. At this time, the marking pen 72 flips over so that the tip of the pen contacts the rail baffle body 100, and marks the corresponding color along the surface of the rail baffle body 100. After marking is completed, the contact plate 73 is released, the torsion spring 71 is reset, and the marking pen 72 flips upward. This process is repeated to mark each piece of rail baffle body 100.

[0033] like Figure 7 and Figure 10 As shown, it also includes a connecting frame 8, a connecting frame 8 is provided at the bottom of the lower roller frame 2, an operating lever 81 is rotated on the connecting frame 8, and a worm 82 is symmetrically provided on the operating lever 81, and a position adjustment plate 84 is rotated on the left and right sides of the bottom plate of the lower roller frame 2 respectively, and a worm wheel 83 is provided at the bottom of the rotating end of the position adjustment plate 84, which is meshed with the worm 82 on the same side.

[0034] like Figure 10 As shown, contact ends 85 are also included. Contact ends 85 are arranged at intervals on the top of the position adjustment plates 84. By driving the operating rod 81 to rotate, the worm 82 rotates and engages with the corresponding worm wheel 83, driving the position adjustment plates 84 to rotate and tilt synchronously, so that the spacing between the position adjustment plates 84 on both sides is adapted to the width of the rail baffle body 100 to be transported, ensuring that the contact ends 85 can contact and limit the position of the rail baffle body 100, thereby adjusting the center position of the rail baffle body 100.

[0035] It can be seen that, through the synergistic effect of various components, the present invention constructs an efficient and continuous rail gauge baffle compressive strength testing device. The tilted lower roller frame 2 and upper roller frame 21 realize the automatic feeding and continuous testing of multiple samples. The stabilizing component 4 and the limiting component 5 ensure that each baffle to be tested can be accurately fixed and positioned in the test position, reducing manual intervention and improving the test accuracy and efficiency. At the same time, the support plate 6, the turntable 62 and its push plate 63 are further introduced to realize automatic feeding. The rotating rod 7 and its marking pen 72 distinguish different batches of samples, and the spacing of the position adjustment plate 84 is adjusted through the connecting frame 8 and the operating rod 81 to adapt to samples of different widths and ensure centering. The overall design improves the continuity and detection speed of multi-workpiece processing, enhances the reliability and automation level of the detection process, and significantly improves production efficiency and product quality control capabilities.

[0036] While the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised which do not depart from the scope of the invention.
