TECHNICAL FIELD

[0001] The present application relates to the field of supervision and inspection, in particular to a shotcrete support structure detection equipment. BACKGROUND

[0002] Shotcrete is a kind of concrete which is constructed by spraying. There are two construction methods for shotcrete, namely dry mixing method and wet mixing method. Generally, the dry mixing method is adopted. Shotcrete is prepared by mixing cement, sand and stones with a maximum particle size of 25mm at a certain ratio, and then the mixture is fed into a spraying machine. Compressed air is used to transport the dry mixture along the pipeline to the spraying head, where the mixture is mixed with water and sprayed onto the working surface at a speed of 40-60m / s. Wet mixing method is to mix the raw materials with water in advance before spraying.

[0003] After the concrete is sprayed at the construction site, the operator needs to detect the flatness of the sprayed site and other detections. The conventional flatness detection device uses laser marking to detect the flatness, which cannot directly detect the concave degree of the uneven concrete compared with other positions. SUMMARY

[0050] With reference to Figure 5 and Figure 6The third control assembly is arranged in the mounting base 1 and comprises a limiting plate 36. The second clamping block 34 is provided with a fifth sliding groove in the height direction thereof. The control rod 33 and the limiting plate 36 are in sliding fit with the inner side wall of the fifth sliding groove.

The end portion of the connecting rod away from the limiting plate 36 penetrates into the third sliding groove 351 and is fixedly connected with the second driving rod 37.

[0052] With reference to Figure 4 and Figure 6 When the control rod 33 is pushed by the wall and the second return spring 332 is compressed, the control rod 33 moves towards the mounting base 1 relative to the conical block 2. The fifth clamping block 362 on the control rod 33 pushes the fourth clamping block 361 to move. The movement of the fourth clamping block 361 causes the second clamping block 34 to move. The movement of the second clamping block 34 pushes the first clamping block 31 to move. At this time, the first clamping block 31 pulls the spur gear 15 to stop meshing with the bevel gear 14. The first clamping block 31 moves towards the third clamping block 35. The third clamping block 35 is in clamping connection with the first clamping groove on the first clamping block 31.

[0053] With reference to Figure 4 and Figure 6 When the conical block 2 approaches the wall, the control rod 33 first contacts the wall. The second return spring 332 continuously pushes the control rod 33 to move following the movement of the conical block 2. When the control rod 33 is pushed by the wall and the second return spring 332 is compressed, the control rod 33 moves towards the mounting base 1 relative to the conical block 2. Since the control rod 33 is in clamping connection with the second clamping block 34, the control rod 33 pushes the second clamping block 34 to move at this time. The movement of the second clamping block 34 abuts against the first clamping block 31. The movement of the second clamping block 34 continuously pushes the first clamping block 31 to move. When the control rod 33 moves to be flush with the conical block 2 (i.e., the conical block 2 and the control rod 33 simultaneously contact the wall), the first clamping block 31 pulls the spur gear 15 to stop meshing with the bevel gear 14 at this time. The conical block 2 stops moving.

[0054] The implementation principle of the shotcrete support structure detection equipment is as follows: the motor 16 is started, the motor 16 drives the first driving rod 18 to rotate, the first driving rod 18 rotates to drive the plurality of straight gears 15 to rotate simultaneously, the straight gears 15 rotate to drive the corresponding bevel gears 14 to rotate, the bevel gears 14 rotate to drive the first screw rod 12 to rotate, and the first screw rod 12 rotates to drive the corresponding conical blocks 2 to move;

[0055] When the conical block 2 approaches the wall, the control rod 33 first contacts the wall, the second return spring 332 continuously pushes the control rod 33 to move along with the movement of the conical block 2, after the control rod 33 is pushed by the wall and the second return spring 332 is compressed, the control rod 33 moves to the mounting base 1 relative to the conical block 2, the control rod 33 pushes the second clamping block 34 to move due to the clamping of the second clamping block 34, the second clamping block 34 moves and abuts against the first clamping block 31, and the second clamping block 34 continuously pushes the first clamping block 31 to move, when the control rod 33 moves to the same level as the conical block 2 (i.e., the conical block 2 and the control rod 33 contact the wall at the same time), the first clamping block 31 pulls the straight gear 15 to stop meshing with the bevel gear 14 at this time, and the first clamping block 31 moves to the third clamping block 35, and the third clamping block 35 is clamped with the first clamping groove on the first clamping block 31.

[0056] When the conical block 2 finishes testing the flatness of the wall, the operator drives the second driving rod 37 to move, the second driving rod 37 moves to make the limiting plate 36 away from the second clamping block 34, after the limiting plate 36 is away from the second clamping block 34, the fifth clamping block 362 loses the limiting effect of the fourth clamping block 361, under the action of the second return spring 332, the control rod 33 returns to the initial position, at the same time, the third clamping block 35 is away from the first clamping block 31 and is disengaged from the clamping of the first clamping groove, under the action of the first return spring 32, the first clamping block 31 returns to the initial position, and the first clamping block 31 simultaneously pushes the second clamping block 34 to move to the initial position;

[0057] Due to the flatness problem of the wall surface, the time when each movable sleeve 11 reaches the initial position is different, when a certain movable sleeve 11 first reaches the initial position, the sleeve ring 13 moves to the unthreaded position of the first screw rod 12, the sleeve ring 13 stops moving, and the movable sleeve 11 corresponding to the sleeve ring 13 stops moving; by arranging the movable sleeve 11, the first driving assembly and the first control assembly 3, when the wall is not flat, the moving distances of the movable sleeves 11 are different, and the stop positions of the conical blocks 2 are different, at this time, the operator can intuitively know the flatness of each position of the wall through the moving distances of the movable sleeves 11.

[0058] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
