Description

Technical Field

[0001] This invention relates to the field of strength testing equipment technology, and in particular to a device for testing the compressive strength of railway track gauge baffles. Background Technology

[0002] Track gauge blocks are indispensable fastening and adjustment components in railway track systems, maintaining the standard distance between rails to ensure the safety and stability of train operation. During production, specialized stamping and shearing equipment is used for precise cutting and punching of the blocks. After production, to ensure the quality of each batch, product samples need to undergo strength testing. Additionally, some track gauge blocks are manufactured using injection molding; these samples also require strength testing after production to ensure they meet usage standards. Currently, universal testing machines are used for testing, where the block is fixed by clamps and pressure is applied using cylinders. However, this method can only test a single workpiece at a time, and samples must be reloaded and unloaded between each test cycle, making it inefficient for batches requiring at least five samples to be tested. Furthermore, the limitation to testing only a single workpiece creates intervals and discontinuous processing when testing multiple workpieces.

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

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a railway gauge baffle compressive strength testing device with continuous multi-workpiece testing function.

[0005] The technical implementation scheme of the present invention is as follows: a device for testing the compressive strength of railway gauge baffles, comprising:

[0006] The machine frame consists of two frames, with a lower roller frame and an upper roller frame arranged at an angle between the two frames.

[0007] Two cylinders are respectively located on the front side of the frame, and each cylinder has a push rod on its extension and retraction end for applying pressure to the rail baffle body.

[0008] A stabilizing component for securing the detection position of the rail guard plate body includes mounting brackets respectively mounted on two frames, with an upper pressure plate and a lower pressure plate sliding between the two mounting brackets, and each mounting bracket is equipped with a driving component that drives the upper pressure plate and the lower pressure plate respectively.

[0009] The limiting component includes a contact frame disposed between two mounting brackets. The contact frame has symmetrically arranged protruding ends. A retaining frame slides symmetrically on the lower pressure plate. An elastic element is disposed between the retaining frame and the inner wall of the lower pressure plate. An inclined block that contacts and cooperates with the protruding ends on the same side is also disposed inside the retaining frame. A movable frame passes through and slides on the lower roller frame. A stop block that limits the position of the rail baffle body is disposed at the top of the movable frame. An elastic element is disposed between the stop block and the lower roller frame. A contact block that contacts and slides with the retaining frame is disposed at the bottom of the movable frame.

[0010] Furthermore, the drive assembly includes drive motors respectively mounted on the mounting bracket. The output end of each drive motor is connected to a drive gear located in the corresponding mounting bracket. Both sides of the upper pressure plate are provided with rack 1 that meshes with the drive gear on the same side. Both sides of the lower pressure plate are provided with rack 2 that meshes with the drive gear on the same side. The rack 2 and the rack 1 on the same side are arranged opposite to each other so that the upper pressure plate and the lower pressure plate operate in opposite directions.

[0011] Furthermore, it also includes support plates, with a through groove on the lower roller frame, and a support plate on each side of the through groove. A turntable rotates between the two support plates, and push plates arranged circumferentially on the turntable for pushing the rail baffle body to feed. A motor with its output end connected to the rotating end of the turntable is also installed on one of the support plates.

[0012] Furthermore, it also includes rotating rods, with rotating rods on both sides of the upper roller frame. Torsion springs are installed between the rotating rods and the outer wall of the upper roller frame. Marking pens are also installed on the rotating rods, and contact plates that contact and cooperate with the rail baffle body are installed on the other side of the rotating rods.

[0013] Furthermore, it also includes a connecting frame, with a connecting frame at the bottom of the lower roller frame. An operating lever is rotatably mounted on the connecting frame, and worm gears are symmetrically mounted on the operating lever. A position adjustment plate is rotatably mounted on each side of the lower roller frame, and a worm wheel that meshes with the worm gear on the same side is mounted at the bottom of the rotating end of each position adjustment plate.

[0014] Furthermore, it also includes contact ends, with contact ends arranged at intervals on the top of the position adjustment plate.

[0015] Furthermore, both card frames have wedge-shaped ends on opposite sides, with the bottom surface of the wedge-shaped ends being flat.

[0016] Furthermore, the upper and lower roller frames are inclined downwards from back to front.

[0017] This invention offers the following advantages: By tilting the lower and upper roller frames, multiple rail gauge baffles can be continuously tested in a single operation, significantly improving testing efficiency. Furthermore, the coordinated operation of the stabilizing and limiting components, utilizing the combined action of the upper and lower pressure plates, ensures the stable position of the rail gauge baffle during testing, reducing manual intervention and enhancing the stability and accuracy of the testing process. The limiting component design ensures that each baffle is accurately positioned in the testing location and remains stable throughout the testing process, avoiding testing errors caused by inaccurate positioning or insecure fixing. This design not only guarantees the reliability of the overall testing results but also supports the continuous processing of multiple workpieces, further improving production efficiency.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: A device for testing the compressive strength of railway gauge baffles, such as... Figures 1-6 As shown, it includes:

[0031] The frame 1 has two components, with a lower roller frame 2 and an upper roller frame 21 inclinedly arranged between the two frames 1. The wheels on the lower roller frame 2 and the upper roller frame 21 are distributed vertically opposite each other, and both of them show a tendency to gradually tilt downwards from back to front. The rotation of the wheels themselves is used to assist in pushing the rail baffle body 100, and gravity is also used to enable the rail baffle body 100 to move forward automatically for feeding, thereby ensuring its stable forward movement and realizing the detection, transportation and processing of multiple samples.

[0032] Two cylinders 3 are respectively set on the front side of the two frames 1, with their telescopic ends facing upwards. Each cylinder 3 has a push rod 31 for applying pressure to the rail baffle 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 baffle body 100 has a specific extended protrusion structure, the push rod 31 can accurately apply pressure and bend this part to effectively achieve the required compressive strength test.

[0033] A stabilizing component 4 is used to stabilize the detection position of the rail baffle body 100. The stabilizing component 4 includes a mounting bracket 41 that is fixedly mounted on two frames 1 respectively. An upper pressure plate 42 and a lower pressure plate 43 slide between the two mounting brackets 41. The upper pressure plate 42 and the lower pressure plate 43 cooperate to fix the detection position of the rail baffle body 100. Each mounting bracket 41 is equipped with a driving component that drives the upper pressure plate 42 and the lower pressure plate 43 respectively, ensuring the automation of their operation and making the operation of the device more consistent.

[0034] The limiting component 5 includes a contact frame 51 fixedly disposed between the lower front sides of two mounting brackets 41. The contact frame 51 is located below the lower pressure plate 43. The contact frame 51 has symmetrically arranged protruding ends, and the side of the two protruding ends that is far apart from each other has a downwardly inclined surface. A retaining frame 52 is symmetrically slidable on the lower front side of the lower pressure plate 43. Each retaining frame 52 has a wedge-shaped end on its facing side, the bottom surface of which is flat, and the facing sides have a downwardly inclined wedge-shaped surface. An elastic element 53 is disposed between the retaining frame 52 and the inner wall of the lower pressure plate 43. In this embodiment, the elastic element 53 is a spring, which can provide the necessary elastic force for the retaining frame 52 to reset and move. An additional element is disposed within the retaining frame 52. An inclined block 54 is provided to contact and cooperate with the protruding end on the same side. The inclined block 54 and the inclined surface of the corresponding protruding end match each other to achieve stable contact. A movable frame 55 is slidably provided through 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 element 57 is provided between the stop block 56 and the bottom plate of the lower roller frame 2. In this embodiment, the elastic element 57 is a spring, which provides elastic force for the reset movement of the movable frame 55 and the stop block 56. A contact block 58 is provided at the bottom of the movable frame 55 to contact and slide with the frame 52. The left and right sides of the contact block 58 have grooves to facilitate cooperation with the wedge-shaped surface of the frame 52.

[0035] like Figures 3-5 As shown, the drive assembly includes drive motors 44 respectively mounted on mounting brackets 41. Each drive motor 44 has a drive gear 45 connected to its output end within the corresponding mounting bracket 41. Both sides of the upper pressure plate 42 are provided with racks 421 that mesh with the drive gears 45 on the same side. Both sides of the lower pressure plate 43 are provided with racks 431 that mesh with the drive gears 45 on the same side. The racks 431 and racks 421 on the same side are arranged opposite to each other so that the upper pressure plate 42 and the lower pressure plate 43 operate in opposite directions.

[0036] In use, the rail baffle bodies 100 are placed one by one between the lower roller frame 2 and the upper roller frame 21. Due to the inclined setting of the device, the rail baffle bodies 100 will move forward along the inclined trend. At this time, the abutment block 56 is located in front of the lower roller frame 2 and the upper roller frame 21, while the upper pressure plate 42 and the lower pressure plate 43 are in an open state. At the same time, the inclined block 54 contacts the protruding end on the contact frame 51, keeping the two side frames 52 far apart from each other, and the elastic element 53 is in a compressed state.

[0037] As the rail baffle body 100 moves forward, it contacts the abutment block 56, which restricts the movement of the rail baffle body 100. Then, the drive motor 44 is activated, driving the corresponding drive gear 45 to rotate. As the drive gear 45 rotates, it drives the corresponding meshing racks 421 and 431 to move, causing them to move closer together. This, in turn, causes the connected upper pressure plate 42 and lower pressure plate 43 to move closer together 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 clamping frame 52 disengages from the corresponding protruding end of the contact frame 51, the inclined block 54 releases its abutment from the corresponding protruding end, the elastic element 53 resets, and the clamping frames 52 on both sides move closer together and reset as the lower pressure plate 43 moves upward. The pressure plate 43 moves synchronously until the wedge-shaped end of the clamping frame 52 contacts the contact block 58. At this time, the lower pressure plate 43 has not yet contacted the rail baffle body 100. Until the wedge-shaped end of the clamping frame 52 is inserted into the corresponding groove of the contact block 58, the elastic element 53 deforms accordingly. When the lower pressure plate 43 continues to move upward a certain distance and contacts the rail baffle body 100 to achieve clamping, the wedge-shaped end of the clamping frame 52 will also move upward a certain distance along the groove of the contact block 58. This achieves the situation where the upper pressure plate 42, the lower pressure plate 43, and the abutment block 56 jointly restrict the movement of the rail baffle body 100, thereby further stabilizing the detection position of the rail baffle body 100. Then, the cylinder 3 on the corresponding side is activated to drive the connected top rod 31 to move upward to apply pressure to the rail baffle body 100 for strength testing.

[0038] After the test is completed, cylinder 3 resets, drive motor 44 reverses, and drive gear 45 drives rack 421 and rack 431 to move in opposite directions through meshing, causing upper pressure plate 42 and lower pressure plate 43 to separate and reset. After lower pressure plate 43 moves down a certain distance, clamping frame 52 and its wedge-shaped end move down accordingly until the bottom plane of the wedge-shaped end of clamping frame 52 contacts contact block 58 and forms an abutment state, thereby synchronously pulling contact block 58, moving frame 55 and abutment block 56 down synchronously, and elastic element 57 deforms accordingly. At this time, the tested rail baffle body 100 is no longer restricted by abutment block 56 and can continue to move forward. The rail baffle body 100 is discharged, and the subsequent rail baffle body 100 moves forward to replace it until the inclined block 54 contacts the protruding end of the contact frame 51 again. Using its own tilting tendency, the two side frames 52 move away from each other. The elastic element 1 53 returns to the compressed state. At the same time, the frame 52 is released from the restriction of the corresponding contact block 58, and the elastic element 2 57 is reset. The contact block 58, the moving frame 55 and the abutment block 56 move upward synchronously. The abutment block 56 returns to its original position and restricts the position of the replacement rail baffle body 100. This operation is repeated until the rail baffle body 100 in the device has been tested one by one.

[0039] Example 2: Based on Example 1, such as Figure 7 and Figure 8 As shown, it also includes a support plate 6. A through groove 20 with front and rear edges is provided on the bottom plate of the lower roller frame 2. A support plate 6 is fixedly installed on the left and right sides of the through groove 20 respectively. A turntable 62 rotates between the two support plates 6. Push plates 63 are arranged circumferentially on the turntable 62. The push plates 63 are used to push the rail baffle body 100 for automatic material replenishment. A motor 61 with the output end connected to the rotating end of the turntable 62 is also installed on one side of the support plate 6.

[0040] When the tested rail baffle body 100 has finished discharging and a new sample is urgently needed to replace it, the motor 61 is started to drive the turntable 62 to rotate. The push plate 63 pushes the rail baffle body 100 that needs to be replaced forward, so that it can quickly replace the vacant position of the test position, thereby achieving the effect of rapid material replacement.

[0041] like Figure 7 and Figure 9 As shown, it also includes a rotating rod 7. The upper roller frame 21 has rotating rods 7 on both the left and right sides. Torsion springs 71 are provided between the rotating rods 7 and the outer wall of the upper roller frame 21. Marking pens 72 are also provided on the rotating rods 7. The marking pens 72 on both sides are different colors, which can be used to distinguish the rail baffle bodies 100 from different production batches. The other side of the rotating rods 7 is provided with contact plates 73 that contact and cooperate with the rail baffle bodies 100.

[0042] Since the inspection requires testing different production batches of rail baffle bodies 100, the device can be used to differentiate them by placing the rail baffle bodies 100 in reverse order. Specifically, the extended protrusions of rail baffle bodies 100 from different batches are arranged opposite each other. As the rail baffle body 100 tilts forward, its extended protrusions contact the contact plate 73, causing the corresponding rotating rod 7 to rotate and the torsion spring 71 to deform. At this time, the marking pen 72 flips over, its tip contacting the rail baffle body 100, marking the surface of the rail baffle body 100 with the corresponding color. After marking, the contact plate 73 is released, the torsion spring 71 returns to its original position, and the marking pen 72 flips upward, repeating this process to mark each rail baffle body 100.

[0043] like Figure 7 and Figure 10 As shown, it also includes a connecting frame 8. The bottom of the lower roller frame 2 is provided with a connecting frame 8. An operating rod 81 is rotatably mounted on the connecting frame 8. Worms 82 are symmetrically mounted on the operating rod 81. A position adjustment plate 84 is rotatably mounted on the left and right sides of the bottom plate of the lower roller frame 2. The bottom of the rotating end of the position adjustment plate 84 is provided with a worm wheel 83 that meshes with the worm 82 on the same side.

[0044] like Figure 10 As shown, it also includes contact ends 85. The top of the position adjustment plate 84 is arranged with contact ends 85 at intervals. By driving the operating rod 81 to rotate, the worm gear 82 rotates and meshes with the corresponding worm wheel 83, driving the position adjustment plate 84 to rotate and tilt synchronously, so that the distance 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 restrict the position of the rail baffle body 100, thereby adjusting the center position of the rail baffle body 100.

[0045] Therefore, through the synergistic effect of various components, this invention constructs a highly efficient and continuous testing device for the compressive strength of rail gauge baffles. The inclined lower roller frame 2 and upper roller frame 21 enable automatic feeding and continuous testing of multiple samples. The stabilizing component 4 and limiting component 5 ensure that each baffle to be tested is accurately fixed and positioned at the test location, reducing manual intervention and improving testing accuracy and efficiency. Simultaneously, the introduction of a support plate 6, a turntable 62, and its push plate 63 enables automatic material replenishment. A rotating rod 7 and its marking pen 72 distinguish between different batches of samples, and the spacing of the positioning plates 84 is adjusted via a connecting frame 8 and an operating rod 81 to accommodate samples of different widths, ensuring centered positioning. The overall design improves the continuity and testing speed of multi-workpiece processing, enhances the reliability and automation level of the testing process, and significantly improves production efficiency and product quality control capabilities.

[0046] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention.
