Description

Technical Field

[0001] This utility model relates to the field of measuring devices, and in particular to a retaining wall slope measuring device. Background Technology

[0002] A retaining wall is a structure used to keep soil in a specific location. It is commonly found on steep slopes, mounds, or other places where soil sliding or collapse needs to be prevented. The main function of a retaining wall is to resist the lateral pressure of the soil and prevent soil sliding or collapse caused by gravity.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] This utility model provides, for example Figure 1-5 The retaining wall slope measuring device shown. Example

[0051] The system includes a laser positioning device 1, an integrated bracket 2, a mounting frame 3, a connecting component 4, and an adjusting component 5. The laser positioning device 1 emits mutually perpendicular beams. The integrated bracket 2 is located on the side of the laser positioning device 1 and is used to support the laser positioning device 1 at a fixed height. The mounting frame 3 is located outside the laser positioning device 1 and is mounted on the integrated bracket 2 via the connecting component 4. The adjusting component 5 is located between the laser positioning device 1 and the mounting frame 3 and is used to adjust the tilt angle of the laser positioning device 1. When using the laser positioning device 1 to assist in the construction of a retaining wall, firstly, the integrated bracket 2 is used to place the laser positioning device 1 at the designated position, ensuring that the two beams emitted by the laser positioning device 1 are in a horizontal and vertical state, respectively. Then, the mounting frame 3 and the laser positioning device 1 are rotated via the connecting component 4 to make the horizontal beam emitted by the laser positioning device 1 parallel to the construction position of the retaining wall. Then, the tilt angle of the laser positioning device 1 is adjusted via the adjusting component 5 to tilt the vertical beam emitted by the laser positioning device 1 until the tilt angle of the beam is the same as the slope of the retaining wall.

[0052] Furthermore, the adjustment assembly 5 includes a mounting collar 51, a connecting shaft 52, a first connecting housing 53, and a second connecting housing 54. The mounting collar 51 is fixedly mounted on the outside of the laser positioning device 1. The end of the connecting shaft 52 is fixedly connected to the mounting collar 51. The first connecting housing 53 and the second connecting housing 54 are respectively fixedly connected to the ends of the mounting bracket 3. The outer walls of the two connecting shafts 52 are rotatably connected to the first connecting housing 53 and the second connecting housing 54, respectively. Thus, the laser positioning device 1 can rotate relative to the first connecting housing 53 and the second connecting housing 54 through the mounting collar 51 and the two connecting shafts 52, thereby changing the tilt angle of the vertical light emitted by the laser positioning device 1.

[0053] In particular, the adjustment assembly 5 also includes a scale ring 55, a shaft 56, and a pointer 57. The scale ring 55 is fixedly connected to the inside of the second connecting housing 54. One end of the shaft 56 is fixedly connected to the connecting shaft 52. The pointer 57 is fixedly connected to the end of the shaft 56. The pointer 57 is located on the side of the scale ring 55 away from the laser positioning instrument 1. The second connecting housing 54 is equipped with a transparent plate, so as to facilitate the observation of the position of the pointer 57 pointing on the scale ring 55, and thus facilitate the observation of the tilt angle of the laser positioning instrument 1.

[0054] Furthermore, the adjustment assembly 5 also includes a first gear 58, a drive shaft 59, and a second gear 510. The first gear 58 is fixedly installed at the end of the outer wall of the connecting shaft 52. The outer wall of the drive shaft 59 is slidably inserted into the first connecting housing 53. The second gear 510 is slidably engaged with the outside of the drive shaft 59. The second gear 510 is slidably engaged with the outside of the drive shaft 59 by a slider. The diameter of the second gear 510 is much smaller than the diameter of the first gear 58. Thus, rotating the drive shaft 59 can drive the connecting shaft 52 to rotate through the second gear 510 and the first gear 58, thereby changing the tilt angle of the laser positioning device 1.

[0055] Furthermore, the adjustment assembly 5 also includes a limiting plate 511, a fixing block 512, and a locking rod 513. The limiting plate 511 is disposed on the side of the second gear 510 and is fixedly installed inside the first connecting housing 53. The fixing block 512 is fixedly connected to the outside of the drive shaft 59. The end of the locking rod 513 is fixedly connected to the fixing block 512. One side of the limiting plate 511 has multiple locking grooves in a circular array that match the locking rod 513. The locking rod 513 engages with the locking grooves on the limiting plate 511 to lock the drive shaft 59, thereby ensuring the stability of the laser positioning instrument 1 after the tilt angle adjustment is completed.

[0056] Furthermore, the adjustment assembly 5 also includes a protective sleeve 514, a return spring 515, and a plane bearing. The protective sleeve 514 is fixedly connected to the inside of the first connecting housing 53. One end of the outer wall of the drive shaft 59 is located inside the protective sleeve 514. The return spring 515 is sleeved inside the protective sleeve 514. The plane bearing is located between the return spring 515 and the drive shaft 59. The return spring 515 can provide an elastic compressive force to the drive shaft 59 through the plane bearing, thereby ensuring the stability of the drive shaft 59 driving the locking rod 513 to engage with the limit plate 511. Example

[0057] Based on embodiment 1, the integrated bracket 2 includes a tripod 21, a fixed sleeve 22, a support column 23, and a locking bolt 24. The fixed sleeve 22 is fixedly installed on the top of the tripod 21. The outer wall of the support column 23 is slidably sleeved with the fixed sleeve 22. The top of the support column 23 is connected to the connecting assembly 4. The outer wall of the locking bolt 24 is threadedly connected to the fixed sleeve 22. One end of the locking bolt 24 is pressed against the support column 23. Loosening the locking bolt 24 allows the support column 23 to slide relative to the fixed sleeve 22, thereby changing the height of the laser positioning device 1.

[0058] Furthermore, the connecting assembly 4 includes a connecting sleeve 41, a mounting cap 42, a braking block 43, a guide rod 44, and a limiting spring 45. The outer wall of the connecting sleeve 41 is fixedly connected to the mounting frame 3. The connecting sleeve 41 is rotatably sleeved on the top of the outer wall of the support column 23. Under the action of the connecting sleeve 41, the mounting frame 3 can rotate relative to the support column 23, thereby changing the direction of the horizontal beam emitted by the laser positioning device 1. The mounting cap 42 is fixedly connected to the top of the connecting sleeve 41. The braking block 43 is sleeved inside the mounting cap 42. The bottom of the braking block 43 is connected to the support column 23. The guide rod 44 is pressed together with the brake block 43. One end of the guide rod 44 is fixedly connected to the mounting cap 42. The bottom of the outer wall of the guide rod 44 is slidably inserted into the brake block 43. The limiting spring 45 is slidably sleeved on the outside of the guide rod 44. One end of the limiting spring 45 is pressed together with the brake block 43. Under the action of the limiting spring 45, the bottom of the brake block 43 is pressed together with the top of the support column 23, thereby increasing the friction between the connecting sleeve 41 and the support column 23. This ensures the stability of the mounting frame 3 driving the laser positioning device 1 outside the support column 23 when there is no external force.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
