[0001] The utility model belongs to the technical field of track flaw detection, and particularly relates to a flaw detector installation structure for a track flaw detection vehicle. Background Technique

[0002] Track flaw detection is an important means to ensure railway safety. By using professional equipment to detect defects inside and on the surface of the track, it can timely detect hidden dangers such as cracks and wear, prevent accidents from occurring. Advanced flaw detection technologies continuously improve the detection accuracy and efficiency, providing strong support for the stable operation of the railway, and ensuring the safety and smoothness of passenger and freight transportation.

[0003] The existing track flaw detection devices are not convenient for quickly installing the flaw detector, which may lead to too long equipment preparation time, and the track flaw detection vehicle cannot be put into work in time, thus delaying the progress of the entire flaw detection task. When it is necessary to replace the flaw detector to meet different detection requirements, the cumbersome installation process will waste a lot of time, seriously affecting work efficiency and increasing operation costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flaw detector installation structure for a track flaw detection vehicle. By setting an installation mechanism, the problem that the existing track flaw detection devices are not convenient for quickly installing the flaw detector is solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a flaw detector installation structure for a track flaw detection vehicle, including an installation plate. An installation mechanism and an adjustment mechanism are arranged on the installation plate.

[0007] The installation mechanism includes a positioning component and a fixing component. The positioning component includes an installation block fixedly connected to the bottom of the installation plate. A first positioning groove is opened at the bottom of the installation block. A positioning column is fixedly connected to the inner wall of the first positioning groove. Two sliding grooves are opened on the outer wall of the positioning column. A first spring is fixedly connected to the inner bottom wall of each of the two sliding grooves. One end of each of the two first springs far away from the corresponding inner bottom wall of the sliding groove is fixedly connected to a positioning bead. Two second positioning grooves are opened on the inner wall of the first positioning groove. Both of the two positioning beads are slidably connected to the corresponding second positioning groove.

[0008] Furthermore, the fixing component includes a U-shaped groove opened on the inner wall of the installation block. A bidirectional threaded rod is rotatably connected to the inner wall of the installation block. The left end of the bidirectional threaded rod extends to the outside of the installation block. A knob is fixedly connected to the left end of the bidirectional threaded rod.

[0009] Further, two first internal thread blocks are threadedly connected to the bidirectional threaded rod. Both of the two first internal thread blocks are slidably connected to the U-shaped groove. Fixing rods are fixedly connected to the sides of the two first internal thread blocks close to each other. The ends of the two fixing rods close to each other extend into the positioning column and are slidably connected to the positioning column.

[0010] Further, the adjusting mechanism includes a U-shaped plate fixedly connected to the bottom end of the positioning column. A motor is fixedly connected to the top of the U-shaped plate.

[0011] Further, the output shaft of the motor is fixedly connected to a threaded rod through a coupling. The bottom end of the threaded rod extends to the inner bottom wall of the U-shaped plate and is rotatably connected to the U-shaped plate. A second internal thread block is threadedly connected to the threaded rod.

[0012] Further, a sliding rod is fixedly connected to the inner top wall of the U-shaped plate. A slider is slidably connected to the sliding rod. A shock-absorbing plate is fixedly connected between the second internal thread block and the slider.

[0013] Further, a plurality of dampers are fixedly connected to the bottom of the shock-absorbing plate. Springs II are sleeved on the plurality of dampers. A flaw detector is fixedly connected to the bottom ends of the plurality of dampers.

[0014] The utility model has the following beneficial effects:

[0015] 1. By providing the installation mechanism, rotate the knob. The knob drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it drives the first internal thread block to slide in the U-shaped groove. When the first internal thread block moves, it drives the fixing rod to move. Rotate the U-shaped plate. When the U-shaped plate rotates, it drives the positioning column to rotate. When the positioning column rotates, it drives the positioning bead to move. When the positioning bead moves, it drives the first spring to contract. Through the installation mechanism, the installation preparation time of the flaw detector can be reduced, enabling the rail flaw detection vehicle to quickly enter the working state, greatly shortening the operation cycle, improving the work efficiency. At the same time, when flaw detection of different types of rails is required, the old flaw detector can be quickly disassembled and a flaw detector suitable for the new rail can be installed without spending a lot of time on complex installation and debugging processes, thus more flexibly coping with various flaw detection requirements. When the flaw detector fails or needs regular maintenance, it can be quickly removed from the rail flaw detection vehicle for repair and replacement, reducing the equipment downtime and ensuring the continuity of the rail flaw detection work.

[0016] 2. By setting an adjustment mechanism and starting the motor, the motor drives the threaded rod to rotate. When the threaded rod rotates, it drives the second internal thread block to move. When the second internal thread block moves, it drives the shock-absorbing plate to move. When the shock-absorbing plate moves, it drives the slider to slide on the slide rod. When the shock-absorbing plate moves, it drives the flaw detector to move through the damper and spring 2. The adjustment mechanism enables the flaw detector to accurately align with rails of different heights for detection, ensuring the comprehensiveness and accuracy of the flaw detection work. It can easily adapt to different rail heights, expand the application range of the flaw detector, and improve the stability and reliability of the flaw detection work. At the same time, changing the height of the flaw detector can adjust its detection angle with the rail, so that the flaw detection signal can be incident on the rail at a more appropriate angle, thereby improving the detection rate of defects.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A knob 210 is fixedly connected to the left end of the bidirectional threaded rod 29. Two first internally threaded blocks 211 are threadedly connected to the bidirectional threaded rod 29. Both of the two first internally threaded blocks 211 are slidably connected to the U-shaped groove 28. A fixing rod 212 is fixedly connected to one side of each of the two first internally threaded blocks 211 close to each other. One end of each of the two fixing rods 212 close to each other extends into the inside of the positioning column 23 and is slidably connected to the positioning column 23. Through the installation mechanism 2, the installation preparation time of the flaw detector 310 can be reduced, enabling the rail flaw detection vehicle to quickly enter the working state, greatly shortening the operation cycle, and improving work efficiency. At the same time, when flaw detection of different types of rails is required, the old flaw detector 310 can be quickly disassembled and a flaw detector 310 suitable for the new rail can be installed without spending a lot of time on a complex installation and debugging process, thus more flexibly coping with various flaw detection requirements. When the flaw detector 310 fails or needs regular maintenance, it can be quickly removed from the rail flaw detection vehicle for repair and replacement, reducing the equipment downtime and ensuring the continuity of the rail flaw detection work.

[0028] The adjusting mechanism 3 includes a U-shaped plate 31 fixedly connected to the bottom end of the positioning column 23. A motor 32 is fixedly connected to the top of the U-shaped plate 31. The output shaft of the motor 32 is fixedly connected to a threaded rod 33 through a coupling. The bottom end of the threaded rod 33 extends to the inner bottom wall of the U-shaped plate 31 and is rotatably connected to the U-shaped plate 31. An internally threaded block 34 is threadedly connected to the threaded rod 33. A sliding rod 35 is fixedly connected to the inner top wall of the U-shaped plate 31.

A plurality of dampers 38 are fixedly connected to the bottom of the shock-absorbing plate 37. A second spring 39 is sleeved on each of the plurality of dampers 38. The bottom ends of the plurality of dampers 38 are fixedly connected to a flaw detector 310. By means of the adjusting mechanism 3, the flaw detector 310 can accurately align with rails of different heights for detection, ensuring the comprehensiveness and accuracy of the flaw detection work, being able to easily adapt to different rail heights, expanding the applicable range of the flaw detector, improving the stability and reliability of the flaw detection work. At the same time, changing the height of the flaw detector 310 can adjust its detection angle with respect to the rail, enabling the flaw detection signal to enter the rail at a more appropriate angle and improving the defect detection rate.

[0029] A specific application of this embodiment is as follows: Rotate the knob 210. The knob 210 drives the bidirectional threaded rod 29 to rotate. When the bidirectional threaded rod 29 rotates, it drives the internally threaded block 211 to slide within the U-shaped groove 28. While the U-shaped groove 28 provides a space for the internally threaded block 211 to move, it can also limit the internally threaded block 211, converting the rotational motion of the internally threaded block 211 into a linear motion. When the internally threaded block 211 moves, it drives the fixed rod 212 to move, thereby causing the fixed rod 212 to move away from or contact the positioning column 23. When the fixed rod 212 moves away from the positioning column 23 and is no longer in contact with it, rotate the U-shaped plate 31. When the U-shaped plate 31 rotates, it drives the positioning column 23 to rotate. When the positioning column 23 rotates, it drives the positioning bead 26 to move. When the positioning column 23 rotates, it rubs against the first positioning groove 22. Under the pressure of the first positioning groove 22, the positioning bead 26 moves towards the inside of the sliding groove 24. As the positioning column 23 rotates, the pressure continuously increases until the positioning bead 26 is completely retracted into the sliding groove 24. When the positioning bead 26 retracts, it drives the first spring 25 to contract. When the positioning bead 26 is completely disengaged from the second positioning groove 27, the positioning column 23 can be disengaged from the first positioning groove 22, and then the positioning column 23 can be disassembled from the mounting plate 1, thus completing the disassembly of the flaw detector 310. Therefore, it is convenient to quickly disassemble and install the flaw detector 310, reducing the equipment preparation time, enabling the rail flaw detection vehicle to quickly enter the working state, greatly shortening the operation cycle, and improving the work efficiency.

[0030] Start the motor 32, and the motor 32 drives the threaded rod 33 to rotate. When the threaded rod 33 rotates, it drives the internal threaded block 2 34 to move. When the internal threaded block 2 34 moves, it drives the shock-absorbing plate 37 to move. When the shock-absorbing plate 37 moves, it drives the slider 36 to slide on the slide rod 35. The internal threaded block 2 34 is limited by the internal threaded block 2 34 and the slide rod 35, and the rotational motion of the internal threaded block 2 34 is converted into linear motion. When the shock-absorbing plate 37 moves, the flaw detector 310 is driven to move through the damper 38 and the spring 2 39, thereby adjusting the height of the flaw detector 310, so that the flaw detector 310 can adapt to the requirements of rail flaw detection at different heights within a certain range. At the same time, when the flaw detection vehicle vibrates, the vibration is dispersed and buffered by the damper 38 and the spring 2 39, thereby preventing the vibration from being transmitted to the flaw detector 310 and causing damage to the flaw detector 310.
