Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flatness measurement, in particular to a slope construction flatness reference measurement device. BACKGROUND

[0002] In modern civil engineering, especially in the construction of infrastructure such as roads, railways, water conservancy, etc., the construction quality of the slope directly relates to the stability and safety of the overall project. The flatness of the slope surface, as one of the important indicators to measure its construction quality, must be accurately measured and effectively controlled during the construction process.

[0003] In the prior art, there are some auxiliary devices for improving the efficiency and accuracy of slope flatness detection. For example, a patent with the publication number CN119756243A discloses a slope construction flatness detection auxiliary device, which includes a mobile vehicle, a cross beam hinged to one side of the mobile vehicle, a guide block slidingly connected to the cross beam, and a test device fixedly installed on one side of the guide block. The device includes a drive box fixed to the lower side of the guide block, a central tube connected to the lower end of the drive box, and a first test rod rotatably connected to the central tube. The above-mentioned patent controls the movement of the roller on the slope surface. When the roller encounters a protruding obstacle, the internal plug will move upward, thereby lifting the cover plate at the lower end of the liquid injection pipe, and the stored marking liquid is sprayed to achieve on-site marking of the protruding area.

[0004] However, this technical solution has obvious functional limitations: its marking mechanism relies on the upward displacement of the roller caused by the protruding reaction force, so it can only effectively identify and mark the protruding parts of the slope surface. For the concave or low-lying areas on the slope surface, since the roller will not produce an upward triggering action when passing through, the device cannot start the marking process, and thus cannot achieve visual identification of the concave areas. This defect results in incomplete detection results, making it difficult for subsequent construction personnel to accurately find and handle all uneven areas during flatness repair operations, and easily missing the concave parts, causing incomplete repair and ultimately affecting the overall flatness quality of the slope and the safety of the project. Moreover, the length of its guide rail is fixed and cannot adapt to slopes of different lengths. SUMMARY

[0005] Therefore, the present application provides a slope construction flatness reference measurement device that can overcome the shortcomings of existing flatness detection auxiliary devices, which can only effectively identify and mark the protruding parts of the slope surface, but cannot achieve visual identification of the concave areas.

The retraction mechanism is equipped with a conveying mechanism for transporting the sleeve 20. The retraction mechanism includes a fixed plate 23, a turntable 24, a crossbar 25, a second motor 26, and a rotating rod 27. Two fixed... The mounting plate 23 has a sleeve 20 fixedly connected to the lower part of the left mounting plate 23. A turntable 24 is rotatably connected to the right mounting plate 23, and the sleeve 20 slides through the lower part of the turntable 24. A crossbar 25 is connected to the middle of the left mounting plate 23, and the sleeve 20 is wrapped around the outside of the crossbar 25. A second motor 26 is installed in the middle of the left side of the left mounting plate 23. A rotating rod 27 is rotatably connected inside the crossbar 25, and the two ends of the rotating rod 27 are respectively connected to the output shafts of the turntable 24 and the second motor 26. The conveying mechanism includes a winding mechanism. The turntable 24 has a winding wheel 28, a support rod 29, a guide wheel 30, and a third motor 31. The lower right side of the turntable 24 is rotatably connected to the winding wheel 28, and the sleeve 20 passes around the winding wheel 28.

The third motor 31 is installed on the upper part of the rear support rod 29, and the rear end of the rotation shaft of the upper guide wheel 30 is connected to the output shaft of the third motor 31.

[0032] like Figure 3 As shown, it also includes a fourth motor 32 and a second gear 33. The fourth motor 32 is installed on the top right side of the rotating tube 3, and a notch is opened on the top right side of the rotating tube 3. The output shaft of the fourth motor 32 is connected to the second gear 33, which passes through the notch and meshes with the tooth hole 14.

[0033] like Figure 1 As shown, it also includes a storage frame 34. The lower front side of the mobile vehicle body 1 is connected to the storage frame 34, and the fixing rod 4, splicing rod 7 and mobile seat 10 can be placed in the storage frame 34 when not in use.

[0034] Initially, the movable seat 10 is fitted onto the fixed rod 4, and both the fixed rod 4 and the splicing rod 7 are placed inside the storage frame 34 for easy transport. The two liquid storage tanks 21 each contain an appropriate amount of two different colored marking liquids. When the device is needed, the movable vehicle 1 is first transported to the top of the slope 001, with the rotating tube 3 facing the slope. Then, the controller 1001 controls the fourth motor 32 to start working. The fourth motor 32 drives the second gear 33 to rotate slowly, and then the rotating tube 3 is rotated upwards to a suitable angle to facilitate the subsequent installation of the splicing rod 7. Then, a splicing rod 7 is slowly inserted into the rotating tube 3, and the splicing rod 7... With the toothed hole 14 facing upwards, until the toothed hole 14 on the splicing rod 7 meshes with the second gear 33, the rotation of the second gear 33 drives the splicing rod 7 to move downwards. When the middle section of the splicing rod 7 moves into the interior of the rotating tube 3, the controller 1001 controls the fourth motor 32 to temporarily stop working, causing the splicing rod 7 to temporarily stop moving. Since the fourth motor 32 has a self-locking function, the meshing of the second gear 33 and the toothed hole 14 locks the splicing rod 7 onto the rotating tube 3, preventing the splicing rod 7 from falling off. Then, the threaded engagement of the threaded rod 8 and the threaded hole 9 tightens the fixing rod 4 to the lower end of the splicing rod 7, and the fixing rod... 4. When the splicing rod 7 is aligned with the support rod 7, the rotating tube 3 is released. Under the action of gravity, the rotating tube 3, the splicing rod 7, and the fixing rod 4 will all rotate downwards. The fixing rod 4 drives the roller 16 to rotate downwards until the roller 16 contacts the slope surface. Since the fixing rod 4 and the support rod 15 are set vertically, it can be ensured that the splicing rod 7 and the fixing rod 4 are parallel to the slope surface. Then, the next splicing rod 7 is tightened and fixed to the upper end of the previous splicing rod 7 through the threaded engagement of the threaded rod 8 and the threaded hole 9, so that the two splicing rods 7 are aligned. Then, the fourth motor 32 drives the splicing rod 7 and the fixing rod 4 to move downwards a specified distance. The roller 16 will roll down the slope surface to assist in splicing. The rod 7 and the fixed rod 4 move downwards. Repeating the above operation allows for the selection of an appropriate number of splicing rods 7 based on the actual length of the slope. During the splicing process, whenever the fixed rod 4 moves downwards, the controller 1001 controls the second motor 26 to drive the rotating rod 27 to rotate. The rotating rod 27 drives the right side of the sleeve 20 to rotate, thus removing the sleeve 20 from the outside of the crossbar 25. Simultaneously, the controller 1001 controls the third motor 31 to drive the guide wheel 30 to rotate. The guide wheel 30 transports the removed portion of the sleeve 20 to the right, allowing the sleeve 20 to follow the fixed rod 4 downwards. Once the appropriate number of splicing rods 7 are spliced, as... Figure 1As shown, the electric wheel 6 will be in contact with the ground, and then the first motor 12 will be controlled to work by the controller 1001, the first motor 12 drives the first gear 13 to rotate, through the meshing of the first gear 13 and the tooth hole 14, the moving seat 10 can be driven to move upward along the fixed rod 4 and the spliced rod 7, at the same time, the controller 1001 will control the third motor 31 to drive the wire wheel 30 to reverse, the wire wheel 30 can convey the sleeve 20 to the left to be collected, and the controller 1001 will control the second motor 26 to drive the rotating rod 27 to reverse, the rotating rod 27 drives the right part of the sleeve 20 to reverse, so as to rewrap the collected part of the sleeve 20 outside the cross rod 25, when the moving seat 10 moves to the edge of the slope top, the first motor 12 will be controlled to stop working by the controller 1001, and the moving seat 10 stops moving, thus, all the preparation work has been completed, the value of the pointer 301 on the scale 201 is the inclination angle of the slope surface; then the laser sensor 11 will be controlled to work by the controller 1001, and then the moving seat 10 will be controlled to move slowly downward along the fixed rod 4 and the spliced rod 7 by the controller 1001, the moving seat 10 can drive the laser sensor 11 and the nozzle 17 to move slowly along the slope surface, the laser sensor 11 can detect the distance between the laser sensor 11 and the slope surface in real time, and can upload the detection value of each point on the slope surface to the controller 1001 for analysis and comparison, if the difference between the detection value and the preset value is greater than 1cm, it is determined that the slope surface is uneven, if the detection value is greater than the preset value, the point is a concave part, otherwise it is a convex part (for example, the preset value is 10cm, when the detection value of the point greater than 11cm is determined as a concave part, and when the detection value of the point less than 9cm is determined as a convex part); when the nozzle 17 moves to the concave part, the controller 1001 will control the front liquid pump 22 to work, the front liquid pump 22 will extract the marking liquid in the front liquid tank 21, and spray the marking liquid on the concave part through the front liquid pipe 18 for marking, after the marking is completed, the controller 1001 will control the front liquid pump 22 to stop working, similarly, when the nozzle 17 moves to the convex part, the controller 1001 will control the rear liquid pump 22 to work, so as to spray the marking liquid in the rear liquid tank 21 on the convex part for marking, after the marking is completed, the controller 1001 will control the rear liquid pump 22 to stop working; when the moving seat 10 moves to the edge of the slope bottom, the moving seat 10 will be controlled to stop moving by the controller 1001, and then the moving vehicle body 1 and the electric wheel 6 will be controlled to move backward by a specified distance by the controller 1001, in the moving process, the moving seat 10 needs to be controlled to move upward along the fixed rod 4 and the spliced rod 7 to the edge of the slope top, when the moving vehicle body 1 and the electric wheel 6 stop moving, the above operation is repeated, so that the flatness of the slope surface can be measured and marked again.When the whole slope measurement is completed, the fourth motor 32 is controlled by the controller 1001 to drive the second gear 33 to reverse, the second gear 33 drives the fixed rod 4 and the spliced rod 7 to move upwards, then the spliced rod 7 is twisted and disassembled by the staff, and the disassembled spliced rod 7 and the fixed rod 4 are placed back into the storage frame 34.
