[0002] In mine production and engineering acceptance, it is necessary to measure and inspect the construction quality of medium-deep holes. Factors such as hole depth, inclination angle, azimuth angle, and hole formation quality all determine the blasting quality and the effectiveness of roadway formation. Due to the rudimentary conditions at mine construction sites, the inspection of medium-deep holes in mines currently typically uses a measuring ruler to measure the hole depth. This method has low accuracy, and the measuring ruler's limited length makes it unsuitable for measuring deep holes. Furthermore, excessively long rulers are inconvenient to carry during fieldwork. Existing measuring rulers cannot measure other hole parameters, and other inspection methods are required to assess hole quality, thus failing to meet the needs of measuring and inspecting medium-deep holes in mines.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] To address the aforementioned technical problems in deep hole measurement and inspection in mines, this utility model proposes a comprehensive inspection device capable of simultaneously measuring hole depth and inspecting the quality within the hole.

[0022] Reference Figure 1 and Figure 2 In some embodiments of this utility model, a comprehensive detection device for deep hole detection in mines includes: The hole depth measuring unit 10 includes multiple measuring rulers, each measuring ruler having a strip-shaped structure. The measuring rulers are connected in a sliding fit to form a telescopic structure. A locking mechanism 20 is provided between two slidingly connected measuring rulers, which is used to lock the two measuring rulers. The tilt measuring unit includes a scale 31 and a level 32 mounted on the scale. The scale 31 is mounted on the measuring ruler and is located on the same surface as the measuring ruler. The scale 31 and the measuring ruler are rotatably connected. The flaw detection ball 40 is located at the end of the measuring ruler that can extend to the outermost end of the hole depth measuring unit.

[0023] In some embodiments, the hole depth measuring unit 10 includes a first measuring ruler 11, a second measuring ruler 12, a third measuring ruler 13... and an nth measuring ruler 14, with each measuring ruler being connected in a sliding fit with the others in sequence. For example, the first measuring ruler and the second measuring ruler are connected in a sliding fit, the second measuring ruler and the third measuring ruler are connected in a sliding fit, and so on.

[0024] Reference Figure 1 Taking three measuring rulers as an example, the third measuring ruler 13 is provided with a third receiving groove that cooperates with the second measuring ruler 12, the second measuring ruler 12 is provided with a second receiving groove that cooperates with the first measuring ruler 13, the second measuring ruler 12 is set in the third receiving groove and one end extends out of the third receiving groove, and the first measuring ruler 11 is set in the second receiving groove and one end extends out of the second receiving groove.

[0025] Reference Figure 1 and Figure 4 For example, the second measuring ruler has an L-shaped structure, and an open second receiving groove is formed on the second measuring ruler.

[0026] Reference Figure 2 A locking mechanism 20 for locking the first and second measuring scales is provided on one end of the second measuring scale that extends into the third receiving groove. Correspondingly, a locking mechanism for locking the second and third measuring scales is provided at one end of the third measuring scale.

[0027] In some embodiments, refer to Figure 4 The first measuring ruler 11 and the second measuring ruler 12 are respectively provided with dovetail grooves, and the second measuring ruler 12 and the third measuring ruler 13 are respectively provided with dovetail slide rails. The first measuring ruler and the second measuring ruler, and the second measuring ruler and the third measuring ruler are respectively connected by sliding fit through the dovetail grooves and the dovetail slide rails.

[0028] In some embodiments, such as Figure 3 and Figure 4 As shown, the locking mechanism 20 includes a locking sleeve 21, a cam 22, a pressing block 23, and a trigger 24; The locking sleeve 21 is fitted onto the measuring scale and fixedly connected to the measuring scale by the set screw; The cam 22 is rotatably connected to the locking sleeve 21. A sliding hole 15 corresponding to the position of the cam is provided on the measuring scale. The clamping block 23 is fitted in the sliding hole 15. When the cam rotates, it can apply a pressing force to the clamping block, so that the clamping block applies a pressing force to another measuring scale to lock the measuring scale. The trigger 24 is mounted on the cam 22. The cam is rotated by the trigger to lock and unlock the measuring scales.

[0029] The locking mechanisms installed on each measuring scale are arranged in sequence when the hole depth measuring unit is folded up, which can provide a limit for the position between each measuring scale.

[0030] by Figure 4 Taking the structure in the example, during installation, the clamping block is installed into the sliding hole of the second measuring scale, and then the locking sleeve is put on the second measuring scale from above, and the locking sleeve is fixed on the second measuring scale by the set screw.

[0031] A clearance space is provided on the locking sleeve to facilitate the rotation of the cam, and the cam is positioned to press against the clamping block. The top of the clamping block is designed with an arc shape to facilitate its engagement with the cam.

[0032] Alternatively, a groove can be provided on the top of the clamping block so that when the cam rotates to the clamping state, it falls into the groove, thereby keeping the locking mechanism in the locked state and ensuring the stability of the lock.

[0033] In some embodiments, a mounting support is vertically provided on the nth measuring ruler, and the scale 31 is rotatably connected to the mounting support. When the measuring ruler is horizontal, the level 32 and the nth measuring ruler 14 are arranged parallel to each other.

[0034] During measurement, the hole depth measuring unit is adjusted to a certain length, and the measuring ruler is inserted into the hole to measure the hole depth. At the same time, the scale is rotated to adjust the level to be horizontal. At this time, the angle of the hole can be measured by reading the angle scale on the scale.

[0035] In some embodiments, the flaw detection ball 40 is disposed on one end of the first measuring scale extending out of the second receiving groove. The flaw detection ball 40 is rotatably connected to the first measuring scale 11 to facilitate inserting the flaw detection ball into the hole and inspecting the hole formation quality through the flaw detection ball.

[0036] In some embodiments, such as Figure 5As shown, the flaw detection ball 40 includes two hemispherical shells 41, and a mounting part 42 is provided on the hemispherical shell 41. The two hemispherical shells 41 are rotatably connected to the first measuring scale 11 through the mounting part 42. The flaw detection ball with a two-sided hemispherical shell structure facilitates the installation and removal between the flaw detection ball and the first measuring scale, thereby facilitating the replacement of flaw detection balls of different specifications according to different apertures.

[0037] The hemispherical shell can be made of materials with a certain degree of flexibility and elasticity, such as rubber or plastic, so that the flaw detection ball has a certain degree of passability. By utilizing the tension fit between the flaw detection ball and the inner wall of the hole, the flaw detection ball can be used to smooth the inner wall of the hole, thereby further improving the forming quality of the hole while conducting the inspection.

Therefore, they should not be construed as limitations on this utility model.

[0039] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
