Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway track slabs, specifically a track slab for area flaw detection. Background Technology
[0002] In railway transportation systems, the safety and stability of the tracks directly affect the safe operation of trains. Therefore, it is necessary to conduct flaw detection on railway tracks to inspect for damage within the rails. By detecting problems in advance, issues can be addressed, thereby ensuring the safety of the tracks during use.
[0003] In the inspection pits of maintenance workshops or repair stations, flaw detection track slabs are typically installed. Rails are placed on these slabs for flaw detection, a necessary facility for vehicle inspection, maintenance, and testing. Traditional flaw detection zones are usually designed using a combination of short concrete sleepers or wooden sleepers. While this method results in short maintenance and replacement cycles, it also leads to high maintenance costs. Furthermore, the lack of drainage design prolongs maintenance time and reduces efficiency. Additionally, the traditional short sleeper connection method cannot effectively maintain track stability, potentially causing track deformation or creating safety hazards. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a flaw detection track plate that can reduce maintenance costs and improve inspection efficiency.
[0005] To solve the above-mentioned technical problems, the present invention includes a plate body, the structural feature of which is that a bearing area is provided in the center of the plate body, and multiple rail bearing platforms capable of bearing rails are installed on the bearing area. The rail bearing platforms are arranged in two rows, and the two rows of rail bearing platforms are arranged left and right and parallel to each other. The two rows of rail bearing platforms can respectively support two rails of the railway. A drainage ditch is provided on the plate body, and an inlet and an outlet are provided on the side wall of the drainage ditch.
[0006] With the above structure, the slab is installed in a maintenance workshop or pit. Two rows of rail support platforms are arranged parallel to each other, allowing rails to be placed on them side-by-side. Two rails are placed on the two rows of support platforms, ensuring their stability. A drainage ditch is also provided on the slab. When rails are placed on the support platforms, various flaw detection methods can be used, including ultrasonic testing. Ultrasonic testing often requires a coupling agent, but in practice, water is frequently used. Water is added through the inlet to provide the coupling agent, improving efficiency. The water, acting as the coupling agent, falls into the drainage ditch, preventing water accumulation on the track slab and affecting the inspection process. Excess water is drained through the outlet. When other materials are used as the coupling agent, the water used to wash the coupling agent falls into the drainage ditch for easy cleaning and collection, further improving flaw detection efficiency.
[0007] The rail support platform is provided with bolt holes that run vertically through it. The rail support platform is fixed to the bearing area by bolts. The rail support platform can be replaced and can be adapted to rails of different widths, increasing the applicability of the flaw detection rail plate.
[0008] The drainage system includes two transverse drainage channels and two longitudinal drainage channels. The transverse drainage channels are located on the front and rear sides of the two rows of rail support platforms. The longitudinal drainage channels connect the two transverse drainage channels. The transverse drainage channels are symmetrically arranged along the center line of the front-to-back direction of the slab, and the longitudinal drainage channels are symmetrically arranged along the center line of the left-to-right direction of the slab. The transverse drainage channels are located on the front and rear sides of the rail support platforms and are parallel to the direction of the rails, which can collect water from all places and improve collection efficiency. The longitudinal drainage channels connect the two transverse drainage channels and ensure water collection, thereby facilitating water flow in the drainage channels and improving maintenance efficiency.
[0009] The upper opening of the drainage ditch is provided with a stepped surface, which diverts water. As the water flows down the stepped surface, the water flow speed is slowed down, the impact is mitigated, and the impact on rail flaw detection is avoided.
[0010] The inlet and outlet are equipped with inlet and outlet pipes, which are directly generated during the pouring process by pre-burying the inlet and outlet pipes.
[0011] The lower end face of the drainage ditch is inclined, and the height of the lower end face of the drainage ditch gradually decreases towards the outlet, so that the water flows towards the outlet. When water needs to be discharged, it is convenient for the water to flow towards the outlet.
[0012] The upper surface of the bearing area is inclined, and the center line of the upper surface of the bearing area is the highest in the front-to-back direction. The height of the upper surface of the bearing area gradually decreases from the center line to both the front and rear ends. The upper surface of the bearing area is inclined, and the transverse drainage ditch is located on the front and rear sides of the rail support platform. It is located on the lower side of the upper surface of the bearing area. The water flows along the upper surface to both the front and rear sides and enters the drainage ditch, which avoids water accumulation on the upper surface of the bearing area and improves the applicability of the flaw detection track plate.
[0013] The plate is provided with grouting holes and venting holes, which are located on the center line of the front and rear direction of the plate. The grouting and venting holes are used to complete the grouting and production of the track plate.
[0014] The plate body is provided with lifting sleeves for hoisting. The lifting sleeves are set at the front and rear ends and are symmetrically arranged to facilitate the hoisting and demolding of the track plate and to facilitate its movement.
[0015] In summary, this utility model has the advantages of saving costs, high efficiency, and strong applicability. Attached Figure Description

[0021] like Figure 1-5 As shown, this utility model is a regional flaw detection track slab, which includes a slab body 1, on which transverse and longitudinal drainage grooves 4 are provided, and a bearing area 2 for mounting a track support platform 3 is provided in the middle of the slab body 1. For ease of description, let... Figure 1 Left is left, right is right. Let... Figure 1 The upper side is the front, and the lower side is the rear. Multiple rail support platforms 3 are installed at the center of the plate 1. The rail support platforms 3 are arranged in two rows, parallel to each other in the left-right direction. The track slab with this flaw detection area is placed in the inspection pit of the maintenance workshop or repair station, with the rail support platforms 3 protruding upwards. Two rails are placed on the rail support platforms 3 respectively, followed by the inspection and maintenance of the railway rails. For flaw detection, water can be used as a coupling agent to achieve ultrasonic flaw detection of the rails. Other coupling agents can also be used. After ultrasonic flaw detection, the coupling agent needs to be rinsed off. The plate 1 is equipped with a water channel 4, which allows water to be provided as a coupling agent or excess water to be drained and replaced, enabling quick completion of the work and improving maintenance efficiency. The plate 1 is equipped with grouting holes 71 and venting holes 72, which are located on the center line of the front-rear direction of the plate 1. The grouting and production of the track slab are completed through the grouting holes and venting holes 72. The plate 1 is equipped with a lifting sleeve 73 for hoisting. The lifting sleeve 73 is set at both the front and rear ends and is symmetrically arranged to facilitate the hoisting and demolding of the track plate and to facilitate its movement.
[0022] like Figure 1-5As shown, the rail support platform 3 is fixed to the bearing area 2 of the plate 1 by bolts. The rail support platform 3 can be replaced to adapt to the flaw detection process of rails with different gaps. The distance between the transverse center lines of the two rows of rail support platforms 3 is slightly larger than the rail gauge. In this embodiment, the distance between the transverse center lines of the two rows of rail support platforms 3 is 1445mm. Since the standard rail gauge is 1435mm, the distance between the center lines of the rail support platforms 3 ensures that the two rails with the standard gauge are placed on the two rows of rail support platforms 3 respectively without falling off, providing a stable bearing structure. The upper surface of the bearing area 2 is an inclined surface. The highest point of the upper surface of the bearing area 2 is at the center line of the plate 1 in the front-back direction. It gradually decreases towards the front and back sides along the center line of the plate 1. The upper surface of the bearing area 2 is an inclined surface. When water flows onto the upper surface of the bearing area 2, due to the inclined upper surface, the water flows into the drainage ditch 4, which facilitates drainage and avoids water accumulation on the bearing area 2, which would affect the flaw detection effect. There are 10 support platforms in total, with 5 in each row. The two rows of support platforms are symmetrically arranged to maintain the stability of the rails.
[0023] like Figure 1-5 As shown, the drainage ditch 4 includes a transverse drainage ditch 41 arranged laterally and a longitudinal drainage ditch 42 arranged longitudinally. There are two transverse drainage ditches 41, located at the front and rear sides of the bearing area 2, and also at the front and rear sides of the support platform 3. The two transverse drainage ditches 41 penetrate from the left end face to the right end face of the plate 1, and are symmetrically arranged. There are two longitudinal drainage ditches 42, both located between the transverse drainage ditches 41. The longitudinal drainage ditches 42 transversely penetrate the bearing area 2. The two longitudinal drainage ditches 42 are symmetrically arranged. The bottom surface of the drainage ditch 4 is inclined, with one side higher than the other in the front-to-back direction. In this embodiment, the inclination angle of the bottom surface of the drainage ditch 4 is 1°. In other embodiments, the inclination angle of the bottom surface of the drainage ditch 4 can be other angles. An outlet 6 and an inlet 5 are provided on the outer end face of the transverse drainage ditch 41 at the lowest point of the inclination of the drainage ditch 4. In this embodiment, the bottom surface of the front side of the drainage ditch 4 is higher than that of the rear side. At the rear end of the drainage ditch 4, there is an inlet 5 and an outlet 6 that penetrate the side wall of the transverse drainage ditch 41 in a front-to-back direction. The positions of the inlet 5 and the outlet 6 correspond to those of the longitudinal drainage ditch 42. The inclined bottom surface of the drainage ditch 4 allows water to flow towards the lower part of the bottom surface and then be discharged from the outlet 6. The correspondence between the outlet 6 and the inlet 5 and the longitudinal drainage ditch 42 increases the drainage efficiency. At the same time, the drainage ditch 4 is designed in a stepped shape, which diverts water through the stepped surface. When the water flows down the stepped surface, the water flow speed is slowed down, the impact is mitigated, and the impact on rail flaw detection is avoided, significantly improving maintenance efficiency.
[0024] like Figure 1-5As shown, the track slab in the flaw detection area adopts an integrated design, forming a stable support structure. This design not only improves the load-bearing capacity of the track but also effectively reduces the types of materials used in the track. High-strength concrete is used to increase the durability and impact resistance of the track slab, facilitating installation and maintenance. It also reduces the possibility of track deformation, thereby improving maintenance safety.
