[0002] During the process of mine exploitation, the existence of geological fractures poses a serious threat to the safe production of mines. For example, ground subsidence and landslides may lead to the occurrence of geological disasters. At present, the methods for exploring geological fractures in mines mainly use tape measures, altimeters, etc. During the exploration process of geological fractures, when measuring the width of a certain fracture, for the specific distance of the width of a certain fracture, generally only the position angle of the tape measure across the fracture is visually estimated manually, resulting in a large error between the exploration data of the fracture at a certain position and the actual data.

[0003] Therefore, it is necessary to provide a rapid exploration device for mine geological fractures to solve the problems raised in the above background art. Summary of the Invention

Thereafter, during the adjustment process when the sliding seat rotates around the measuring rod I, under the action of the spring, the measuring rod II can be in contact with the crack wall in real time. Therefore, when the measuring point on one side of the crack measured by the measuring rod I is determined, the corresponding point on the other side of the crack can be quickly and accurately surveyed, and the high-precision data in the survey data can be obtained, so that the crack can be quickly and accurately surveyed.

[0020] Referring to Figures 1-4 , the present invention provides a technical solution: a rapid survey device for mine geological fractures, including a suitcase 1, a horizontal telescopic cylinder 2 is installed on the suitcase 1, a loading box 3 is installed at the output end of the telescopic cylinder 2, a rotating shaft 4 and a control mechanism 5 for controlling the rotation of the rotating shaft 4 are rotatably installed at the lower end of the loading box 3, a survey shell frame 6 is fixed at the lower end of the rotating shaft 4, a horizontal belt 7 and a reversible motor 2 71 for controlling the transmission of the belt 7 are installed in the survey shell frame 6, a moving seat 72 is installed on the belt 7, a reciprocating moving seat 8 is installed on the moving seat 72, a measuring rod 2 10 is installed on the reciprocating moving seat 8, and a measuring rod 1 9 coaxial with the rotating shaft 4 is also installed at the lower end of the survey shell frame 6.

[0021] In this embodiment, the reciprocating moving seat 8 includes a shell plate frame 81 installed at the lower end of the moving seat 72, a slide bar 82 parallel to the belt 7 is installed in the shell plate frame 81, a slide seat 83 is slidably sleeved on the slide bar 82, two sides of the slide seat 83 are respectively connected to the shell plate frame 81 through springs 84, and the measuring rod 2 10 is connected to the lower end of the slide seat 83; wherein, after the spring 84 deforms, the spring 84 can drive the measuring rod 2 10 to maintain contact with the side wall of the fracture, so as to record the change in the position of the receiver 14 driven by the movement of the slide seat 83, thereby positioning and obtaining the fracture width distance with the best accuracy, and further making the measured fracture width distance more accurate. Specifically, when the measuring rod 2 10 is adjusted to contact the crack wall of the fracture, continuously adjust the measuring rod 2 10 to lean towards the crack wall. At this time, the measuring rod 2 10 is forced to drive the slide seat 83 to move, and after moving to a certain extent, stop adjusting the measuring rod 2 10. Thereafter, during the adjustment process when the slide seat 83 rotates around the measuring rod 1 9 as the axis, under the action of the spring 84, the measuring rod 2 10 can be in contact with the crack wall of the fracture in real time. Therefore, when determining the measuring point on one side of the fracture measured by the measuring rod 1 9, the corresponding point on the other side of the fracture can be quickly and accurately surveyed, and thus the fracture can be quickly and accurately surveyed.

[0022] In this embodiment, the first measuring rod 9 and the second measuring rod 10 are both cylindrical structures, so that the first measuring rod 9 can rotate on its own axis, and the second measuring rod 10 can move along the surface of the crack, reducing the friction effect between it and the crack surface and improving the accuracy of the survey data.

[0023] In this embodiment, the first measuring rod 9 is rotatably connected to the survey housing frame 6, and the second measuring rod 10 is rotatably connected to the sliding seat 83.

[0024] In this embodiment, a first pressure sensor 91 for detecting the first measuring rod 9 is installed on the survey housing frame 6, and a second pressure sensor 101 for detecting the second measuring rod 10 is installed on the sliding seat 83. The first pressure sensor 91 is used to detect the degree and state of the pressure on the first measuring rod 9, and the second pressure sensor 101 is used to detect the degree and state of the pressure on the second measuring rod 10.

[0025] In this embodiment, an infrared ranging sensor 13 is installed on the survey housing frame 6, and a receiver 14 for receiving the signal of the infrared ranging sensor 13 is installed on the sliding seat 83. The distance between the first measuring rod 9 and the second measuring rod 10 is surveyed by the infrared ranging sensor 13 and the receiver 14.

[0026] In this embodiment, a telescopic frame 11 is installed at the lower end of the suitcase 1, and a fixed support 12 is installed at the lower end of the telescopic frame 11.

[0027] In this embodiment, symmetric arc surfaces 121 are provided on the fixed support 12, and the cross-section of the arc surface 121 is arranged in the same plane as the telescopic cylinder 2. That is to say, in order to adjust the inclination direction of the telescopic frame 11 before completely fixing the telescopic frames 11.

[0028] In this embodiment, the control mechanism 5 includes a first forward and reverse motor 51 installed in the transfer box 3. A spur gear 53 is installed at the output end of the first forward and reverse motor 51, and the spur gear 53 is meshed with a spur gear ring 52 fixedly sleeved on the rotating shaft 4.

[0029] In specific implementation, the surveyor holds the suitcase 1, selects the area to be surveyed for the geological cracks in the mine, selects the positioning point on one side of the crack in the surveyed area, aligns the fixed support 12 with the positioning point, with the arc surface 121 facing the direction of the crack. Then, by controlling the suitcase 1 and the telescopic frame 11, the survey shell frame 6 is made to span above the crack. After adjusting the preliminary position of the survey shell frame 6, the telescopic frame 11 is fixed. After the preliminary positioning of the positions of the telescopic frame 11 and the survey shell frame 6 is completed, the survey of the crack begins. Through the coordinated control of the telescopic cylinder 2 and the telescopic frame 11, first, the measuring rod one 9 and the measuring rod two 10 are adjusted to a certain extent in the crack. Then, the telescopic cylinder 2 retracts, and the measuring rod one 9 starts to move towards the side wall of the crack. When the pressure sensor one 91 shows a detected value, it indicates that the measuring rod one 9 touches the side wall of the crack. Optionally, when the detected value reaches the first certain degree value, the telescopic cylinder 2 stops telescoping to ensure that the measuring rod one 9 is in a better contact state with the side wall of the crack. Then, the positive and negative motor two 71 controls the belt 7 to drive the moving seat 72 to move, and the measuring rod two 10 is adjusted to be close to the other side wall of the crack. When the pressure sensor two 101 shows a detected value, it indicates that the measuring rod two 10 touches the other side wall of the crack. And when the detected value of the pressure sensor two 101 reaches the second degree value, the moving seat 72 stops moving. That is to say, at this time, the sliding seat 83 drives the spring 84 to deform. After the sliding seat 83 moves a certain distance, the spring 84 has a reset effect on the sliding seat 83. At this time, the initial distance between the measuring rod one 9 and the measuring rod two 10 is measured by the infrared distance measuring sensor 13. Then, the positive and negative motor one 51 in the control mechanism 5 drives the spur gear 53 to drive the spur gear ring 52 to rotate, so that the rotating shaft 4 first drives the survey shell frame 6 to rotate clockwise. The clockwise dynamic distance between the measuring rod one 9 and the measuring rod two 10 is measured by the infrared distance measuring sensor 13. The positive and negative motor one 51 rotates in the reverse direction, so that the survey shell frame 6 rotates counterclockwise to reset, and continuously drives the survey shell frame 6. The counterclockwise dynamic distance between the measuring rod one 9 and the measuring rod two 10 is measured by the infrared distance measuring sensor 13. Among them, if the clockwise dynamic distance is greater than the initial distance and the counterclockwise dynamic distance is also greater than the initial distance, the initial distance is the width of the crack. If the clockwise dynamic distance is greater than the initial distance and the counterclockwise dynamic distance is first less than the initial distance and then greater than the initial distance, the counterclockwise distance at the turning point of the counterclockwise dynamic distance is the width of the crack. If the clockwise dynamic distance is less than the initial distance and the clockwise dynamic distance is first less than the initial distance and then greater than the initial distance, the clockwise distance at the turning point of the clockwise dynamic distance is the width of the crack. Thus, the geological cracks in the mine can be surveyed quickly, efficiently, and with high precision. Among them, when the clockwise dynamic distance is less than the initial distance, the positive and negative motor one 51 only needs to drive the survey shell frame 6 to rotate clockwise.
