Description

Technical Field

[0001] This invention belongs to the field of slope detection technology, specifically relating to an auxiliary device for detecting the flatness of slope construction. Background Technology

[0002] In modern construction engineering, slope flatness testing is a crucial step in ensuring project quality and safety. Flatness directly affects the stability and durability of the slope, thus impacting the overall lifespan of the project and the safety of the surrounding environment. Therefore, scientific and rigorous testing of slope flatness is of paramount importance.

[0003] CN202121116991.1 discloses a slope angle and flatness measuring device. The device is placed on a slope surface with its bottom surface touching the slope, and a digital angle meter displays the slope angle. When measuring flatness, a laser rangefinder slides along a guide rail, and the readings represent the flatness data at various points on the slope. However, this flatness measuring device requires multiple repositionings and measurements during the flatness testing process. Each repositioning requires calibration, which can lead to inaccurate results and slow down the measurement speed. Furthermore, no protrusions are marked after measurement, which can cause omissions in flatness repair work during subsequent work, resulting in missed repair points. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for detecting the flatness of slopes during construction, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for detecting the flatness of slope construction includes a mobile vehicle with a hinged crossbeam on one side. A guide block is slidably connected to the crossbeam, and a testing device is fixedly connected to one side of the guide block. The testing device includes a drive box, which is fixed to the lower side of the guide block. A central tube is fixedly connected to the lower end of the drive box, and a first test rod is rotatably connected inside the central tube. The drive box is used to drive the first test rod to rotate. When the mobile vehicle moves horizontally, the lower end of the first test rod travels on the slope. When the first test rod passes over a protruding surface, it sprays marking liquid downwards, thereby marking the protruding area of ​​the slope.

[0007] Preferably, a rotating connecting collar is provided on the outside of the central tube, two cantilever beams are fixedly connected to the collar, a slider is slidably connected to the cantilever beams, a push-pull device for driving the slider to move is installed on the cantilever beams, and a second test rod is installed on the slider.

[0008] Preferably, the first test rod includes a base rod, a sliding hole at the lower end of the base rod, a sliding rod slidably connected in the sliding hole, a first spring fixedly connected between the bottom of the sliding hole and the sliding rod, a center hole at the center of the base rod, a spray pipe fixedly connected in the center hole, a plug fixedly connected at the upper end of the spray pipe, a clearance hole on the plug, an installation hole at the top of the base rod, an injection pipe fixedly connected in the installation hole, a slot at the lower end of the injection pipe, a cover plate connected in the slot via a second spring, and a roller rotatably connected to one side of the lower end of the sliding rod.

[0009] Preferably, a connecting beam is fixed to one side of the slide rod, and the connecting beam passes through the relief groove on one side of the slide rod. A ring is fixedly connected to one end of the connecting beam, and a telescopic rod is fixedly connected to the ring. The slide block is provided with two longitudinal holes. The second test rod slides up and down in one of the longitudinal holes, and is slidably connected to the longitudinal rod in the other longitudinal hole. The telescopic rod is fixed to the lower end of the longitudinal rod. Both the longitudinal rod and the second test rod are provided with racks on one side. A gear is rotatably connected to the upper side of the slide block through a bracket, and both racks mesh with the gear.

[0010] Preferably, a rangefinder is installed on one side of the drive box.

[0011] The technical effects and advantages of this invention are as follows: The slope flatness testing auxiliary device provided by this invention can slowly test the flatness of a slope by moving a mobile vehicle forward gradually, eliminating the need for multiple installations and corrections, thus improving testing efficiency. Furthermore, when raised areas are detected on the slope, they can be marked with a colored solution for high visibility. A second testing rod can be used to locate and mark the diffusion boundaries at both ends of the raised areas. During the testing process, a rangefinder monitors the slope flatness in real time. The first testing rod and the rangefinder can mutually verify each other, ensuring the accuracy of the test. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides, for example Figure 1-6 The illustrated auxiliary device for detecting the flatness of slope construction includes a mobile vehicle 1, with a hinged crossbeam 2 on one side of the mobile vehicle 1. The crossbeam 2 has a guide groove, and guide blocks 21 are slidably connected in the guide groove. In this embodiment, two guide blocks 21 are used. A transmission rod 22 is rotatably connected in the guide groove. The transmission rod 22 has a left-hand threaded part and a right-hand threaded part. One of the guide blocks 21 has a left-hand threaded hole. The left-hand threaded part is threaded in the left-hand threaded hole, and the right-hand threaded part is threaded in the right-hand threaded hole. A motor is mounted on the crossbeam 2, and the motor is used to drive the transmission rod 22 to rotate, thereby enabling the guide blocks 21 to slide horizontally back and forth in the guide groove, thereby changing the distance between the two guide blocks 21.

[0020] A testing device 3 is fixedly connected to one side of the guide block 21. The testing device 3 includes a drive box 31, which is fixed to the lower side of the guide block 21. A central tube 32 is fixedly connected to the lower end of the drive box 31. A first testing rod 4 is rotatably connected inside the central tube 32. A rotational power device is installed inside the drive box 31, which can drive the first testing rod 4 to rotate. When the moving vehicle 1 moves horizontally, the lower end of the first testing rod 4 travels on the slope. When the first testing rod 4 passes over a raised surface, it sprays marking liquid downwards, thereby marking the raised area of ​​the slope. At the same time, a rangefinder 10 is installed on one side of the drive box 31. The rangefinder 10 monitors the flatness of the slope in real time. The first testing rod 4 and the rangefinder 10 can verify each other to ensure the accuracy of the test.

[0021] The first test rod 4 includes a base rod 41. The lower end of the base rod 41 is provided with a sliding hole, and a sliding rod 42 is slidably connected in the sliding hole. A first spring 45 is fixedly connected between the bottom of the sliding hole and the sliding rod 42. The base rod 41 is provided with a center hole, and a spray pipe 44 is fixedly connected in the center hole. A plug 47 is fixedly connected to the upper end of the spray pipe 44. A clearance hole 471 is provided on the plug 47. The top of the base rod 41 is provided with a mounting hole, and an injection pipe 46 is fixedly connected in the mounting hole. A slot is provided at the lower end of the injection pipe 46, and a cover plate 461 is connected in the slot through a second spring 462. A roller 49 is rotatably connected to one side of the lower end of the sliding rod 42. When roller 49 encounters a protrusion, it will drive slide bar 42 to move upward. At this time, plug 47 is inserted upward into the lower end of injection tube 46 and lifts cover plate 461. Marking liquid enters injection tube 46 through the gap between injection tube 46, cover plate 461 and card groove wall, and clearance hole 471, thereby spraying marking liquid onto slope surface. In this way, protruding parts of slope can be marked directly during inspection. Workers can intuitively find uneven parts and there will be no leakage during repair.

[0022] The above-described testing method has the following drawbacks: during the test, only the protruding parts within a local linear area of ​​the slope can be tested, and the specific location of the spread beyond the protruding parts cannot be determined. Therefore, this embodiment further improves upon this by using a rotating collar 33 on the outer side of the central tube 32. Two cantilever beams 34 are fixedly connected to the collar 33, and sliders 35 are slidably connected to the cantilever beams 34. A push-pull device 36 for driving the sliders 35 to translate is mounted on the cantilever beams 34, and a second test rod 9 is mounted on the sliders 35. The structure of the second test rod 9 is the same as that of the first test rod 4, and will not be described again here. A connecting beam 43 is fixed to one side of the slide rod 42. The connecting beam 43 passes through the relief groove on one side of the slide rod 42. One end of the connecting beam 43 is fixedly connected to a ring 5. A telescopic rod 71 is fixedly connected to the ring 5. The slider 35 is provided with two longitudinal holes. The second test rod 9 slides up and down in one of the longitudinal holes and slides in the other longitudinal hole to connect with the longitudinal rod 7. The telescopic rod 71 is fixed to the lower end of the longitudinal rod 7. Both the longitudinal rod 7 and the second test rod 9 are provided with racks on one side. A gear 8 is rotatably connected to the upper side of the slider 35 through a bracket. Both racks mesh with the gear 8. When the first test rod 4 rises, the ring 5, telescopic rod 71, and longitudinal rod 7 also rise. Under the action of the gear rack, the second test rod 9 descends, and then the first test rod 4 is driven to rotate via the drive box 31. This causes the ring 5 and cantilever beam 34 to reciprocate, with the rotation angle controlled within ±10°, thus achieving the function of finding the protruding boundary. The position of the slider 35 can be changed by the push-pull device 36 to test the protruding boundary. When the second test rod detects a protrusion, a marking liquid is sprayed. This achieves the purpose of flatness testing. It should be noted that when the push-pull device 36 changes the position of the slider 35, the lower side of the second test rod must be in a suspended state. If it is not in a suspended state, the second test rod may damage the slope.

[0023] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0024] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 invention should be included within the protection scope of the present invention.
