Figure 2 It is a schematic structural diagram of a pointer 107 and a scale 108 according to the first embodiment of the utility model.

[0020] The roadbed structural layer material defect detection device of the utility model includes a main rod body 101, a cross arm 102, a sliding sleeve 103, a measuring rod 104, a top block 105, an adjustment rod 106, a pointer 107, a scale 108, a bubble level 109, a locking screw 110, and a limit block 111, which solves the problem that the prior art needs to use the second measured scale to subtract the first measured scale, and the detection steps are relatively cumbersome, thereby affecting the detection efficiency. It can be understood that the above scheme can also be used to improve the problem of detection efficiency.

[0021] In this embodiment, the main rod body 101 is a square cylinder with a handle on the side, which is convenient for controlling the main rod body 101 and facilitating measurement operations. The measuring component is installed on the main rod body 101, so that the thickness of the roadbed structure layer can be conveniently and directly measured, which solves the problem of the prior art that the detection steps are cumbersome due to the need to subtract the first measured scale from the second measured scale, thereby affecting the detection efficiency.

[0022] The cross arm 102 is fixedly connected to the main rod body 101 and is located at one side of the main rod body 101. The sliding sleeve 103 is fixedly connected to the cross arm 102 and is located at a side of the cross arm 102 away from the main rod body 101. The measuring rod 104 passes through the sliding sleeve 103 and is slidably connected to the sliding sleeve 103. The top block 105 is fixedly connected to the measuring rod 104 and is located at the top end of the measuring rod 104. The adjusting rod 106 passes through the measuring rod 104 and is slidably connected to the measuring rod 104 and is located at an end of the measuring rod 104 away from the top block 105. The pointer 107 is fixedly connected to the top block 105 and is located at the top block 1 05 top, the scale 108 is fixedly mounted on the main rod body 101 and is located on the side of the main rod body 101 close to the pointer 107, the cross arm 102 is mounted on the middle position of the side of the main rod body 101, and is perpendicular to the main rod body 101, the sliding sleeve 103 is a hollow rectangular sleeve, the measuring rod 104 is a square cylinder, passing through the sliding sleeve 103, the outer wall of the measuring rod 104 is in contact with the inner wall of the sliding sleeve 103, the sliding sleeve 103 can guide the measuring rod 104, so that the measuring rod 104 can only slide vertically, the top block 105 is fixedly mounted on the top of the measuring rod 104, when the top block 105 is in contact with the cross arm 1 02, the measuring rod 104 can no longer move downward, the adjusting rod 106 is an L-shaped square column, the bottom end of the measuring rod 104 is provided with a through hole, the adjusting rod 106 passes through the through hole and is slidably connected to the measuring rod 104, and the position of the detection point can be flexibly adjusted by sliding the adjusting rod 106. When the top block 105 contacts the cross arm 102, the lowest end of the adjusting rod 106 is flush with the bottom end of the main rod body 101. There are two pointers 107, which are symmetrically arranged on the top of the top block 105. The two pointers 107 are respectively located on both sides of the main rod body 101, and the scale 108 is two pieces, corresponding to the two pointers 107 respectively. The scale 108 is arranged vertically with the zero scale position facing downward. When the top block 105 contacts the cross arm 102, the pointer 107 just points to the zero scale. The pointer 107 can accurately reflect the difference between the bottom end of the main rod body 101 and the bottom end of the adjusting rod 106. By placing the bottom end of the main rod body 101 at the bottom of the roadbed structure layer and the bottom end of the adjusting rod 106 at the top of the roadbed structure layer, the value of the pointer 107 on the scale 108 can be read to measure the thickness of the roadbed structure layer. The detection steps are simple, which solves the problem that the prior art needs to subtract the first measured scale from the second measured scale, and the detection steps are complicated, thereby affecting the detection efficiency.

[0023] Secondly, the bubble level 109 is horizontally installed on the cross arm 102. The bubble level 109 is horizontally installed on the side of the cross arm 102 to facilitate the leveling of the cross arm 102. Leveling the cross arm 102 can ensure that the main rod body 101 and the measuring rod 104 are in a vertical state, reducing measurement errors. Through the bubble level 109, the accuracy of the measurement can be ensured.

[0024] At the same time, the locking screw 110 is threadedly connected to the measuring rod 104 and is located at one end of the locking screw 110 close to the adjusting rod 106. A threaded hole is provided on the measuring rod 104, and the locking screw 110 can be inserted into the measuring rod 104 through the threaded hole to abut against the adjusting rod 106. By tightening the locking screw 110, the end of the locking screw 110 abuts against the adjusting rod 106, and the adjusting rod 106 is locked under the action of friction.

[0025] In addition, the limit block 111 is fixedly connected to the adjusting rod 106 and is located at the end of the adjusting rod 106. The limit block 111 can prevent the adjusting rod 106 from slipping off the measuring rod 104. The limit block 111 can limit the adjusting rod 106.

[0026] In this embodiment, when in use, the bottom end of the main rod body 101 is placed at the bottom of the roadbed structure layer, and then the bottom end of the adjusting rod 106 is placed at the top of the roadbed structure layer. At this time, the difference between the bottom end of the main rod body 101 and the bottom end of the adjusting rod 106 will be directly reflected by the pointer 107 and the scale 108. The reading indicated by the pointer 107 is the thickness of the roadbed structure layer. During the measurement process, the adjusting rod 106 can be slid to adjust the position of the bottom end of the adjusting rod 106. After the position is adjusted, the locking screw 110 is tightened to lock it. In addition, during the measurement process, the level can be observed through the bubble level 109 to ensure the accuracy of the measurement. The present application can directly reflect the thickness of the roadbed structure layer through the pointer 107, without calculating the measured value. Compared with the prior art, the steps are simplified, the detection efficiency is improved, and the problem that the prior art needs to use the second measured scale to subtract the first measured scale, and the detection steps are cumbersome, thereby affecting the detection efficiency.
