[0021] The probe adjusting mechanism 11 comprises a lifting groove 1101, an electric push rod 1102, a lifting plate 1103, a limiting plate 1104, a limiting groove 1105, a T-shaped groove 1106, a T-shaped block 1107, a moving plate 1108, a threaded rod 1109, a motor 1110, a stabilizing block 1111, a connecting plate 1112, a connecting block 1113 and a probe 1114. The inner side surface of the box body 1 is provided with the lifting groove 1101. The inner side surface of the lifting groove 1101 is fixedly connected with the electric push rod 1102. One end surface of the electric push rod 1102 is fixedly connected with the lifting plate 1103. One side surface of the lifting plate 1103 is fixedly connected with the limiting plate 1104. The inner side surface of the lifting groove 1101 is provided with the limiting groove 1105. The lower surface of the lifting plate 1103 is provided with the T-shaped groove 1106. The inner side surface of the T-shaped groove 1106 is slidably connected with the T-shaped block 1107. The lower surface of the T-shaped block 1107 is fixedly connected with the moving plate 1108. The inner side surface of the moving plate 1108 is threadedly connected with the threaded rod 1109. One end surface of the threaded rod 1109 is fixedly connected with the motor 1110. The outer side surface of the threaded rod 1109 is rotatably connected with the stabilizing block 1111. The lower surface of the moving plate 1108 is fixedly connected with the connecting plate 1112. The lower surface of the connecting plate 1112 is fixedly connected with the connecting block 1113. One side surface of the connecting block 1113 is threadedly connected with the probe 1114. Through the arrangement of the lifting groove 1101, the electric push rod 1102, the lifting plate 1103, the limiting plate 1104, the limiting groove 1105, the T-shaped groove 1106, the T-shaped block 1107, the moving plate 1108, the threaded rod 1109, the motor 1110, the stabilizing block 1111, the connecting plate 1112, the connecting block 1113 and the probe 1114, when the electric push rod 1102 receives a control signal and starts to work, the push rod of the electric push rod 1102 will perform a telescopic movement, driving the lifting plate 1103 to move up and down in the lifting groove 1101. The limiting plate 1104 fixedly connected with one side of the lifting plate 1103 will slide in the limiting groove 1105 together with the lifting plate 1103, thereby driving the moving plate 1108 and the probe 1114 to lift. When the motor 1110 starts, the threaded rod 1109 will perform a rotary movement. The threaded rod 1109 rotates in the stabilizing block 1111. When the threaded rod 1109 rotates, the moving plate 1108 will perform a linear movement on the threaded rod 1109, driving the probe 1114 to move in the horizontal direction. At the same time, the T-shaped block 1107 above the moving plate 1108 slides in the T-shaped groove 1106 below the lifting plate 1103. The connecting plate 1112 below the moving plate 1108 is fixedly connected with the connecting block 1113.

[0023] Further, the inner size of the fixed column 8 is consistent with the outer size of the rotating shaft 9, and the pulley 10 is provided with two groups on the lower surface of the box body 1. Through the arrangement of the fixed column 8 and the rotating shaft 9, when the device moves on the track, the pulley 10 will swing with the ups and downs of the track surface. The fixed column 8 limits the rotating shaft 9 to prevent the rotating shaft 9 from shaking or deviating, so that the pulley 10 moves more smoothly.
[0024] Further, the lifting plate 1103 is in sliding connection with the lifting groove 1101, and the outer size of the limiting plate 1104 is consistent with the inner size of the limiting groove 1105. Through the arrangement of the limiting groove 1105 and the limiting plate 1104, in use, the limiting groove 1105 limits the limiting plate 1104 to ensure that the lifting plate 1103 can only move smoothly in the vertical direction, preventing the lifting plate 1103 from deviating or shaking, and enabling the probe 1114 connected to the lifting plate 1103 to be accurately adjusted in the vertical direction.
[0025] Further, the limiting plate 1104 is provided with two groups symmetrically about the central axis of the lifting plate 1103, and the stabilizing block 1111 is fixedly connected with the moving plate 1108. Through the arrangement of the limiting plate 1104, in use, the limiting plate 1104 is provided with two groups symmetrically about the central axis of the lifting plate 1103, which further enhances the stability of the moving plate 1108, enabling the lifting plate 1103 to smoothly drive the probe 1114 to rise or fall.
[0026] Further, the T-shaped block 1107 is provided with two groups on the upper surface of the moving plate 1108, and the probe 1114 is provided with multiple groups on the lower surface of the connecting plate 1112. Through the arrangement of the T-shaped block 1107, in use, the two groups of T-shaped blocks 1107 improve the load capacity of the moving plate 1108, enabling the moving plate 1108 to stably drive the probe 1114 to adjust in the horizontal direction when the number of probes 1114 is large or heavy.
[0027] Further, the connecting block 1113 is provided with two groups on both sides of the probe 1114, and the probe 1114 is fixedly connected with the connecting block 1113 through bolts. Through the arrangement of the probe 1114 and the connecting block 1113, in use, the probe 1114 is fixedly connected with the connecting block 1113 through bolts. In the use process, different types of probes 1114 can be replaced according to different detection requirements. When the probe 1114 is damaged, it can be quickly replaced, thereby improving the practicability of the equipment and the convenience of maintenance.
[0028] Working principle: the operator holds the pushing handle 6 on the upper side of the box body 1 and applies a pushing force. The pulley 10 rolls on the track surface, thereby driving the whole device to move along the track to the position to be detected. When the device needs to be carried to a position far away or inconvenient to push, the two groups of carrying handles 7 arranged on the side surface of the box body 1 can be used to lift the device for carrying. The flaw detector 3 is fixed on the upper side of the box body 1. When the device moves to the detection position, the flaw detector 3 starts to emit a flaw detection signal. The signal emitted by the flaw detector 3 acts on the track surface through the probe 1114 in the probe adjusting mechanism 11 below, interacts with the track material, and generates a feedback signal which is received by the probe 1114 and then transmitted back to the flaw detector 3. The display screen 5 presents the data received by the flaw detector 3 in the form of intuitive images or numerical values to the operator. The operator can observe the content on the display screen 5 to judge whether the track has defects and the position, size and other information of the defects. The detector 2 is used to observe the track and transmit information to the probe adjusting mechanism 11 to adjust the position of the probe 1114. When the electric push rod 1102 receives a control signal to start working, the push rod of the electric push rod 1102 will perform a telescopic movement, driving the lifting plate 1103 to move up and down in the lifting groove 1101. The limiting plate 1104 fixedly connected to one side of the lifting plate 1103 will slide in the limiting groove 1105 together with the lifting plate 1103, thereby driving the moving plate 1108 and the probe 1114 to lift. When the motor 1110 starts, the threaded rod 1109 rotates in the stable block 1111. When the threaded rod 1109 rotates, the moving plate 1108 will move linearly on the threaded rod 1109, driving the probe 1114 to move in the horizontal direction. At the same time, the T-shaped block 1107 above the moving plate 1108 slides in the T-shaped groove 1106 below the lifting plate 1103. The connecting plate 1112 below the moving plate 1108 is fixedly connected with the connecting block 1113. The connecting block 1113 is provided with two groups on both sides of the probe 1114, which can make the probe 1114 more stably installed below the connecting plate 1112.
[0029] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
