Description

Technical Field

[0001] This utility model relates to the technical field of rail flaw detection equipment, specifically to a rail weld flaw detection scanning bracket and its installation structure. Background Technology

[0002] Currently, the flaw detection of weld seams in in-service rails mostly relies on manual flaw detection methods such as ultrasonic single-probe reflection method, dual-probe K-type scanning method, and dual-probe serial scanning method.

[0003] During the above-mentioned flaw detection operation of rail welds, workers need to carry a variety of tools with them. The actual operation steps are complicated and tedious, the workload is quite heavy, and each inspection is time-consuming and inefficient.

[0004] Therefore, there is an urgent need to design a scanning bracket that integrates and supports flaw detection equipment and can automatically position itself on the rail, so as to facilitate workers' flaw detection operations. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a rail weld flaw detection and scanning bracket and its installation structure that can be automatically installed and positioned on the rail or detached from the rail by lifting. The rail weld flaw detection and scanning bracket can be used to arrange flaw detection probes and other components, eliminating the need for workers to carry flaw detection tools with them.

[0006] To achieve this objective, the rail weld flaw detection and scanning bracket designed in this utility model includes a cantilever beam bracket for hoisting and end plate brackets connected to the front and rear ends of the cantilever beam bracket. The end plate bracket includes a fixed end plate that can be vertically supported on the rail surface to initially position the rail weld flaw detection and scanning bracket on the rail, and two hinged end plates that are respectively hinged to the left and right sides of the end of the cantilever beam bracket and arranged parallel to the fixed end plate. The left and right sides of the fixed end plate are respectively hinged to the two hinged end plates by a connecting rod, and the connecting rod is arranged perpendicular to the fixed end plate and the hinged end plates. A self-driving structure is connected between the fixed end plate and the two hinged end plates. Through the self-driving structure, the two hinged end plates can automatically clamp the rail web when the fixed end plate is lowered onto the rail, and automatically release the rail web when the fixed end plate is lifted upward.

[0007] Furthermore, a preliminary positioning plate is fixed to the bottom left and right sides of the fixed end plate, the inner surface of which can fit against the side of the rail head of the rail, so that the fixed end plate is initially positioned on the rail surface of the rail.

[0008] Furthermore, the connecting rod is fixed to the fixed end plate, and the middle part of the hinged end plate is hinged to the connecting rod.

[0009] Furthermore, a hinge rod is connected between the top of the hinged end plate and the cantilever beam support, and the two ends of the hinge rod are respectively hinged to the cantilever beam support and the hinged end plate.

[0010] Furthermore, the self-driving structure includes a crossbar hinged between the middle of the two hinged end plates and a self-lifting mechanism that drives the crossbar to move up and down by being lowered and raised on the rail via the fixed end plate.

[0011] Furthermore, the left and right ends of the crossbar are respectively provided with waist-shaped holes along the length direction of the crossbar, and a positioning rod that can slide in the waist-shaped hole is fixed in the middle of the inner side of each hinge end plate.

[0012] Furthermore, the self-lifting mechanism includes a self-lifting slide fixed to the fixed end plate, and a self-lifting slider that can move up and down is slidably disposed inside the self-lifting slide, and the self-lifting slider is fixed to the crossbar.

[0013] Furthermore, each of the hinged end plates has a rail head positioning half-groove corresponding to the rail head on its inner middle side, and a rail waist positioning half-groove corresponding to the rail web on its inner lower side. The two rail head positioning half-grooves can form a rail head positioning groove that mates with the rail head, and the two rail web positioning half-grooves can form a rail web positioning groove that mates with the rail web. The rail head positioning groove and the rail web positioning groove can form an I-shaped groove structure that mates with the rail.

[0014] Furthermore, a locking device is fixed to the outer surface of the fixed end plate. The locking device can be a magnetic locking device or other locking structures, such as clamping.

[0015] Furthermore, the installation structure of the rail weld flaw detection and scanning bracket includes a rail, and the end plate brackets at the front and rear ends of the cantilever beam bracket are mounted on the front and rear sides of the rail. The fixed end plates at the front and rear ends of the cantilever beam bracket are vertically supported on the rail surface of the rail, and the two hinged end plates at the same end of the cantilever beam bracket clamp the rail through the self-driving structure.

[0016] The beneficial effects of this invention are as follows: The fixed end plate can be vertically supported on the rail surface, enabling the rail weld flaw detection scanning bracket to achieve rapid and accurate initial positioning on the rail. This is like building a stable "working platform" for flaw detection work in a complex rail environment, reducing flaw detection deviations caused by inaccurate positioning, helping to improve the accuracy of flaw detection, and ensuring that the flaw detection area can accurately cover the weld and its surrounding key parts. When the fixed end plate is installed on the rail, the self-driving structure enables the two hinged end plates to automatically clamp the rail web. This automatic clamping mechanism can effectively reduce the complexity and time cost of manual operation, and can ensure that the connection between the bracket and the rail is tight and stable during flaw detection. The tight connection can prevent the flaw detection equipment from shaking or shifting during operation, thereby ensuring that the flaw detection probe can always be kept in the ideal flaw detection position, improving the accuracy and reliability of flaw detection data. When the fixed end plate is lifted upward, the two hinged end plates can automatically release the rail web. This makes the disassembly process of the bracket extremely simple, without the need for complicated tools or additional operating steps to loosen the connection between the bracket and the rail. This significantly improves the efficiency of the entire flaw detection operation, especially in situations requiring frequent support movement for multi-position flaw detection, resulting in substantial time savings. Because the fixed end plate and the hinged end plate are hinged together by a connecting rod, and the clamping and releasing actions are achieved through a self-driven structure, this design allows the support to adapt to rails of different sizes to a certain extent. Whether there are slight differences in rail web width or other variations in rail dimensions, the support can flexibly adjust the clamping state, enhancing its versatility and applicability, and reducing the hassle of needing to replace supports of different specifications due to differences in rail dimensions.

[0017] In summary, the rail weld flaw detection scanning bracket, through its rational structural design, reduces the complexity of the operator's procedures. Workers do not need to spend a significant amount of time and energy manually adjusting and fixing the bracket, allowing them to focus more on operating the flaw detection equipment and monitoring the flaw detection data. This not only improves the efficiency of flaw detection work but also helps to enhance the quality of flaw detection and reduce the probability of flaw detection errors caused by human fatigue or complex operations.

[0027] like Figure 1As shown in Figure 7, in some embodiments, the rail weld flaw detection and scanning bracket designed by this utility model includes a cantilever beam bracket 1 for hoisting and end plate brackets 2 connected to the front and rear ends of the cantilever beam bracket 1. The cantilever beam bracket 1 includes a cantilever beam 1.1 and cantilever beam end blocks 1.2 fixedly connected to its two ends. The end plate support 2 includes a fixed end plate 2.1 that can be vertically supported on the rail surface of the rail 3 and allows the rail weld flaw detection and scanning support to be initially positioned on the rail 3, and two hinged end plates 2.2 that are respectively hinged to the left and right sides of the end of the cantilever beam support 1 and arranged parallel to the fixed end plate 2.1. The left and right sides of the fixed end plate 2.1 are respectively hinged to the two hinged end plates 2.2 by a connecting rod 4, and the connecting rod 4 is arranged perpendicular to the fixed end plate 2.1 and the hinged end plates 2.2. A self-driving structure is connected between the fixed end plate 2.1 and the two hinged end plates 2.2. Through the self-driving structure, the two hinged end plates 2.2 can automatically clamp the rail web of the rail 3 when the fixed end plate 2.1 is placed on the rail 3, and automatically release the rail web when the fixed end plate 2.1 is lifted upward.

[0028] Example 1

[0029] Based on some of the above embodiments, a preliminary positioning plate 2.3 is fixed on the bottom left and right sides of the fixed end plate 2.1, respectively. The inner surface of the plate can fit against the side of the rail head of the rail 3, so that the fixed end plate 2.1 is initially positioned on the rail surface of the rail 3. The structure of the preliminary positioning plate 2.3 allows the fixed end plate 2.1 to be better secured to the rail head of the rail 3.

[0030] Example 2

[0031] Based on some of the above embodiments or Embodiment 1, the connecting rod 4 is fixed to the fixed end plate 2.1, and the middle part of the hinged end plate 2.2 is hinged to the connecting rod 4. The hinged end plate 2.2 can rotate around the connecting rod 4, and the fixed end plate 2.1 is fixed to the connecting rod 4, so that the fixed end plate 2.1, the hinged end plate 2.2, and the connecting rod 4 form a stable integral structure. The connecting rod 4 can be used as a guide rail, on which a probe bracket or slider is arranged (the probe bracket is fixed to the slider), and the probe is installed in the probe bracket, so that the probe can detect along the length direction of the rail 3. Furthermore, through the structure of the connecting rod 4, the probe and the hinged end plate 2.2 can be linked. While the hinged end plate 2.2 clamps the rail 3, the probe can also be in contact with the surface of the rail 3 to realize weld flaw detection.

[0032] Example 3

[0033] Based on some of the above embodiments, or Embodiment 1 or Embodiment 2, a hinge rod 2.4 is connected between the top of the hinged end plate 2.2 and the cantilever beam support 1. The two ends of the hinge rod 2.4 are respectively hinged to the cantilever beam support 1 and the hinged end plate 2.2. The hinged end plate 2.2 and the hinge rod 2.4 form a skeleton-like hinged structure with the cantilever beam support 1, which facilitates the clamping of the hinged end plate 2.2 onto the rail 3.

[0034] Example 4

[0035] Based on some of the above embodiments, or Embodiment 1, Embodiment 2, or Embodiment 3, the self-driving structure includes a crossbar 2.5 hinged between the middle parts of two hinged end plates 2.2 and a self-lifting mechanism that drives the crossbar 2.5 to move up and down via a fixed end plate 2.1 on a rail 3. The left and right ends of the crossbar 2.5 are respectively provided with oblong holes along its length. A positioning rod 5, which can slide within the oblong hole, is fixed to the inner middle of each hinged end plate 2.2. The self-lifting mechanism includes a self-lifting slide block 6 fixed to the fixed end plate 2.1. A self-lifting slider 7, which can move up and down, is slidably disposed within the self-lifting slide block 6 and is fixed to the crossbar 2.5. The crossbar 2.5 is hinged between the middle parts of the two hinged end plates 2.2. Simultaneously, oblong holes are provided at the left and right ends of the crossbar 2.5 along its length, and the positioning rod 5 in the inner middle of each hinged end plate 2.2 can slide within the oblong hole. This design allows the crossbar 2.5 to have a certain adaptive adjustment space when subjected to external force or driven by the self-lifting mechanism. The positioning rod 5 slides within the oblong hole, serving as a guide for the hinged end plate 2.2. When the crossbar 2.5 moves up and down, it can drive the hinged end plate 2.2 to clamp or release the rail 3. The self-lifting slide 6 is fixed to the fixed end plate 2.1, providing a stable support base for the self-lifting slider 7. The self-lifting slider 7 can slide up and down within the self-lifting slide 6 and is fixed together with the crossbar 2.5. This structure allows the self-lifting mechanism to directly and effectively drive the crossbar 2.5 to move up and down. Furthermore, the self-lifting mechanism uses a combination of slide and slider, a relatively compact design. Compared to some complex lifting devices (such as large hydraulic lifting platforms), it has a significant advantage in terms of space occupation. This allows the entire self-driven structure to be installed and used in relatively small spaces, making it particularly suitable for equipment or work scenarios with high space requirements, such as the internal equipment installation of some rail vehicles or the compact workstations of industrial automated production lines.

[0036] Example 5

[0037] Based on certain embodiments, or Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4 described above, each hinged end plate 2.2 has a rail head positioning half-groove 10 corresponding to the rail head of the rail 3 on its inner middle side, and a rail waist positioning half-groove 8 corresponding to the rail web of the rail 3 on its inner lower side. The two rail head positioning half-grooves 10 can form a rail head positioning groove that mates with the rail head of the rail 3, and the two rail waist positioning half-grooves 8 can form a rail waist positioning groove that mates with the rail web of the rail 3. The rail head positioning groove and the rail waist positioning groove can form an I-shaped groove structure that mates with the rail 3. Through the reasonable structural design of the hinged end plate 2.2, the mutual clamping between the hinged end plate 2.2 and the rail 3 is ensured.

[0038] Example 6

[0039] Based on some of the above embodiments, or Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, or Embodiment 5, a magnetic base 9, i.e., a locking device, is fixed to the outer surface of the fixed end plate 2.1. The magnetic bases 9 at both ends of the scanning bracket allow the scanning bracket to be stably installed on the rail 3, further increasing the stability of the scanning bracket.

[0040] Example 7

[0041] Based on some of the above embodiments, or Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, or Embodiment 6, an installation structure for a rail weld flaw detection and scanning bracket is designed, including a rail 3, and end plate brackets 2 at both ends of a cantilever beam bracket 1, which are mounted on the front and rear sides of the rail 3. The fixed end plates 2.1 at both ends of the cantilever beam bracket 1 are vertically supported on the rail surface of the rail 3, and the two hinged end plates 2.2 at the same end of the cantilever beam bracket 1 clamp the rail 3 through a self-driving structure.

[0042] In this invention, a rail weld flaw detection component can be arranged on the scanning bracket to achieve standardized flaw detection operations. The fixed end plate 2.1 can be vertically supported on the rail surface of the rail 3, enabling the rail weld flaw detection scanning bracket to achieve rapid and accurate initial positioning on the rail 3. This is like building a stable "working platform" for flaw detection work in a complex track environment, reducing flaw detection deviations caused by inaccurate positioning, helping to improve flaw detection accuracy, and ensuring that the flaw detection area can accurately cover the weld and its surrounding critical parts. When the fixed end plate 2.2 is installed on the rail 3, the self-driving structure enables the two hinged end plates 2.2 to automatically clamp the rail web of the rail 3. This automatic clamping mechanism can effectively reduce the complexity and time cost of manual operation, and can ensure a tight and stable connection between the bracket and the rail during flaw detection. The tight connection prevents the flaw detection equipment from shaking or shifting during operation, thereby ensuring that the flaw detection probe can always be kept in the ideal flaw detection position, improving the accuracy and reliability of the flaw detection data. When the fixed end plate 2.1 is lifted upwards, the two hinged end plates 2.2 automatically release the rail web. This makes the disassembly process of the bracket extremely simple, requiring no complicated tools or additional steps to loosen the connection between the bracket and the rail 3. This significantly improves the efficiency of the entire flaw detection operation, especially when frequent bracket movement is required for multi-position flaw detection, saving considerable time. Since the fixed end plate 2.1 and the hinged end plate 2.2 are hinged together by the connecting rod 4 and can achieve clamping and loosening actions through a self-driving structure, this design allows the bracket to adapt to rails of different sizes to a certain extent. Whether there are slight differences in the rail web width or other changes in the rail dimensions, the bracket can flexibly adjust the clamping state, enhancing the versatility and applicability of the bracket and reducing the trouble of needing to replace different specifications of brackets due to differences in rail dimensions.

[0043] In summary, the rail weld flaw detection scanning bracket, through its rational structural design, reduces the complexity of the operator's procedures. Workers do not need to spend a significant amount of time and energy manually adjusting and fixing the bracket, allowing them to focus more on operating the flaw detection equipment and monitoring the flaw detection data. This not only improves the efficiency of flaw detection work but also helps to enhance the quality of flaw detection and reduce the probability of flaw detection errors caused by human fatigue or complex operations.
