Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of geological disaster crack measurement, in particular to a geological disaster crack measurement device. Background Art
[0002] A crack measurement device is a special tool for measuring cracks in geological structures, and is widely used in fields such as geological exploration and geological disaster early warning.
[0003] Although the existing geological disaster crack measurement devices can measure the width or depth of cracks individually, they are usually carried out separately. When measuring the crack depth, it is necessary to pre-measure the crack without crossing the crack to obtain a reference value, and then perform cross-crack measurement. In both non-cross-crack measurement and cross-crack measurement, it is necessary to pre-draw multiple placement points in advance. Especially for cross-crack measurement, it is necessary to draw the positions of transducers at equal distances on both sides of the crack, which is more troublesome to operate, wastes a lot of time, and has low efficiency.

A second hinge rod 17 is hinged to the support rod 6. Third hinge rods 18 are respectively hinged to both ends of the second hinge rod 17. The other end of the third hinge rod 18 is hinged to the slider 11.
[0025] Through the cooperative setting of the mounting frame 1, the measuring instrument body, the transducer 2, the clamping plate 3, the first hinge rod 4, the connecting head 5, the lifting component, the support rod 6, the slide cylinder 8, the connecting rod 9, the slide hole 10, the slider 11 and the driving component in the above structure, it is convenient to drive the connecting head 5 to move up and down through the lifting component. The connecting head 5 drives the clamping plate 3 to slide relatively along both sides of the bottom of the mounting frame 1 through the first hinge rod 4. Furthermore, it is convenient for the clamping plate 3 to be clamped on both sides of the crack width. Through the setting of the anti-slip layer 21, it is convenient for the clamping plate 3 to be limited between the cracks. The setting in cooperation with the scale line 15 is convenient to more intuitively obtain the width information of the crack; in addition, the driving component drives the slider 11 to drive the connecting rod 9 and the transducer 2 to move synchronously to both sides of the crack. By rotating the rotating handle, the rotating handle drives the second threaded rod 16.

[0026] Embodiment 2
[0027] On the basis of Embodiment 1, combined with the attached Figure 4 , a connecting plate 19 is connected to the top end of the support rod 6. A spring 20 is connected between the connecting plate 19 and the connecting block 7. The spring 20 is sleeved outside the support rod 6.
[0028] Through the cooperative setting of the support rod 6, the connecting block 7, the connecting plate 19, and the spring 20 in the above structure, the connecting block 7 drives the sliding cylinder 8 and the connecting rod 9 to abut against the base under the elastic force of the spring 20, facilitating the transmission and reception of ultrasonic signals.
[0029] The specific usage method is as follows:
[0030] First, move the sliding cylinder 8 closer to the connecting plate 19 with one hand. At this time, the spring 20 contracts and stores energy, exposing the clamping plate 3.
[0031] Then, by rotating the handle 14, the handle 14 drives the first threaded rod 13 to rotate. The first threaded rod 13 drives the connecting head 5 through the threaded fit with the threaded hole 12. Due to the hinge setting of the first hinge rod 4, the connecting head 5 can only move up and down. The connecting head 5 drives the clamping plate 3 to slide relatively along both sides of the bottom of the mounting frame 1 through the first hinge rod 4, thereby facilitating the clamping plate 3 to be clamped on both sides of the crack width. The anti-slip layer 21 is provided to facilitate the clamping plate 3 to be limited between the cracks. The scale line 15 is provided to facilitate obtaining the crack width information more intuitively.
[0032] Next, apply a coupling agent to the bottom end of the transducer 2. Slowly release the sliding cylinder 8. The sliding cylinder 8 drives the connecting rod 9 and the transducer 2 downward under the reset action of the spring 20, so that the bottom end of the transducer 2 abuts against the ground. Thus, it is convenient to transmit ultrasonic signals through one side transducer 2 and receive ultrasonic signals through the other side transducer 2, thereby facilitating obtaining a set of crack depth information. Then, move the sliding cylinder 8 closer to the connecting plate 19 again. At this time, the spring 20 contracts and stores energy. Drive the second threaded rod 16 with the other hand. The second threaded rod 16 drives one side slider 11 to slide along the sliding hole 10 through the threaded penetration fit with the mounting frame 1. The slider 11 drives the second hinge rod 17 through the same side third hinge rod 18. The second hinge rod 17 drives the other side slider 11 through the second hinge rod 17 on the opposite side, so that the two sliders 11 can approach or move away from each other as needed, thereby driving the connecting rod 9 to drive the transducer 2 to slide into or out of the sliding cylinder 8, thereby facilitating adjusting the distance between the transducer 2 and the crack. Slowly release the sliding cylinder 8. The sliding cylinder 8 drives the connecting rod 9 and the transducer 2 downward under the reset action of the spring 20, so that the bottom end of the transducer 2 abuts against the ground, thereby facilitating obtaining the crack depth information at different transducer 2 spacings. Thus, it is convenient to accurately measure the crack depth.
