Description

Technical Field

[0001] This utility model relates to the technical field of slope detection equipment, specifically a highway slope detection device. Background Technology

[0002] The detection of roadbed slope gradient is a basic testing item stipulated in the highway engineering quality inspection and evaluation standards. The slope gradient of a highway roadbed depends on geological and hydrological conditions, as well as the fill and cut height of the roadbed. Once the design slope gradient is determined, exceeding the specified value during construction will result in increased land occupation and cross-sectional economic costs; conversely, failing to meet the specified value will directly affect the stability of the roadbed and create potential quality hazards. Therefore, slope detection devices are needed to detect road slope gradients.

[0003] In the prior art, CN220018529U discloses a building ground slope detector, including a building slope, a placement plate at the top of the building slope, and a detector body disposed on one side of the placement plate… The detection component 4 is affected by gravity and hangs naturally. The angle between the detection component 4 and the detector body 3 affected by the slope is the slope of the building slope 5. In the above-mentioned prior art, during use, because the lower end of the detection component has a certain weight, the entire device will shake after being placed on the ground. Readings can only be taken after it has completely stopped, which takes a long time and has low measurement efficiency. At the same time, there is no protective device on the outside of the detection component, and external wind may affect the shaking of the detection component, making it difficult to stop and affecting the measurement work.

The support plate 2 is vertically disposed on one side of the upper surface of the base plate 1.

A connecting plate 7 is disposed at the front end of the rotating shaft 12. A counterweight 10 is disposed at the bottom of the connecting plate 7. The front sidewall of the back plate 5 is rotated... The shaft 12 has a scale mark 8 representing an angle centered on its axis. A transparent cover 6 is provided on the front side wall of the back plate 5 to protect the counterweight 10 and the connecting plate 7. A damping assembly is provided at the rear end of the shaft 12 to actively decelerate its rotation. The damping assembly includes a collar 19 and a fixing plate 13. The collar 19 is fitted onto the shaft 12, and multiple limiting rods 15 are provided at the bottom of the collar 19. The fixing plate 13 is located on the rear side wall of the back plate 5 and is positioned corresponding to the limiting rods 15. The limiting rods 15 are vertically slidably connected to the limiting holes 17. A retaining plate 14 is provided at the bottom of each limiting rod 15. A compression spring 16 is provided between the retaining plate 14 and the fixing plate 13. The collar 19 has no friction with the rotating shaft 12 under no external force. A traction rope 21 is provided on the upper part of the collar 19. A protective box 20 is provided outside the damping assembly. The protective box 20 is connected to the rear side wall of the back plate 5. The traction rope 21 movably passes through the top of the protective box 20. The upper part of the rope 21 moves through the horizontal plate 3 to the front side wall of the horizontal plate 3 and is connected to the handle 9; the rear end side surface of the rotating shaft 12 and the inner ring of the collar 19 are respectively provided with anti-slip pads 18; the locking component includes a locking screw 4, the horizontal plate 3 is provided with a through hole 22 and the support plate 2 passes through the through hole 22, the end face of the horizontal plate 3 is provided with a threaded hole 23, the locking screw 4 is screwed to the threaded rod and pressed against the support plate 2; the connecting plate 7 is provided with an alignment port 11 for observing the scale mark 8 at the position corresponding to the scale mark 8.

[0024] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0025] According to the instruction manual Figure 1-6As can be seen, when using this utility model, the height of the horizontal plate 3 and the back plate 5 can be adjusted by the locking parts, making it convenient for personnel to operate the device. During measurement, the personnel place the device on the road surface where the slope to be measured. The base plate 1 is placed on the road surface and is parallel to the road surface. Since the support plate 2 is perpendicular to the base plate 1 and the horizontal plate 3 is parallel to the base plate 1, the horizontal plate 3 is parallel to the road surface. However, since the road surface has an inclination angle, the horizontal plate 3 and the back plate 5 are also inclination. Since the rotating shaft 12 is rotatably connected to the center of the semi-circular back plate 5 at the bottom of the horizontal plate 3, and the front end of the rotating shaft 12 is connected to the connecting plate 7 and the counterweight 10, the connecting plate 7 will eventually be vertical due to the influence of gravity, thus forming an angular difference with the scale mark 8 on the back plate 5 that represents the angle. The personnel take the reading, which is the inclination angle of the road surface and the horizontal plane. The measurement method is simple and convenient. When the device is placed on the road surface, the connecting plate 7 and the counterweight 10 will swing naturally, and the rotating shaft 12 will rotate accordingly. Traditionally, waiting for them to stop naturally wastes a lot of time. This invention uses a damping component at the rear end of the rotating shaft 12 to apply friction, reducing its rotational speed and amplitude, thereby reducing the swing of the connecting plate 7 and the counterweight 10, accelerating their stopping, saving significant time, and improving measurement efficiency. Furthermore, a transparent cover 6 is placed over the connecting plate 7 and the counterweight 10 to prevent wind interference during measurement and to reduce the swing time of the connecting plate 7 and the counterweight 10, further improving measurement efficiency. Simultaneously, it eliminates external interference, improving measurement accuracy.

[0026] The damping assembly includes a collar 19 and a fixing plate 13. The collar 19 is fitted onto the rotating shaft 12. Multiple limiting rods 15 are provided at the bottom of the collar 19. The fixing plate 13 is located on the rear side wall of the back plate 5 and has limiting holes 17 corresponding to the positions of the limiting rods 15. The limiting rods 15 are vertically slidably connected to the limiting holes 17. A retaining plate 14 is provided at the bottom of the limiting rods 15. A compression spring 16 is provided between the retaining plate 14 and the fixing plate 13. The collar 19 has no friction with the rotating shaft 12 when there is no external force. A traction rope 21 is provided on the upper part of the collar 19. During operation, the operator pulls the traction rope 21 to move the collar 19 upwards, causing the lower part of the inner ring of the collar 19 to contact the lower part of the rotating shaft 12, generating friction. This reduces the rotational speed and amplitude of the rotating shaft 12, thereby reducing the swaying of the connecting plate 7 and the counterweight 10, accelerating the stopping process, and saving a significant amount of time. The traction rope 21 pulls the collar 19 upward, causing the limiting rod 15 to slide vertically into the limiting hole 17 of the fixed plate 13, ensuring the stability of the collar 19's movement. The upward movement of the collar 19 drives the limiting rod 15 to move upward, thereby compressing the compression spring 16 between the clamping plate 14 and the fixed plate 13. When the person releases the traction rope 21, the compression spring 16 returns to its original position. After returning to its original position, the collar 19 has no contact with the rotating shaft 12, ensuring the accuracy of the final reading.

[0027] The damping component is covered by a protective box 20, which is connected to the rear side wall of the back plate 5. The traction rope 21 passes through the top of the protective box 20. The protective box 20 protects the damping component and extends its service life.

[0028] The upper part of the traction rope 21 extends through the horizontal plate 3 to the front wall of the horizontal plate 3 and is connected to the handle 9. Pulling the handle 9 is more effortless. Moreover, on the front wall of the back plate 5, it is convenient for personnel to operate the damping component while observing the swing of the connecting plate 7 and the counterweight 10.

[0029] Among them, anti-slip pads 18 are provided on the rear end side surface of the rotating shaft 12 and the inner ring of the collar 19, respectively, to increase the friction of the collar 19 when restricting the rotating shaft 12 and improve the damping effect.

[0030] The locking component includes a locking screw 4. A through hole 22 is provided on the horizontal plate 3 and the support plate 2 passes through the through hole 22. A threaded hole 23 is opened on the end face of the horizontal plate 3. The locking screw 4 is screwed to the threaded rod and pressed against the support plate 2. When adjusting, the locking screw 4 is loosened, and the horizontal plate 3 can be moved up and down. Finally, the horizontal plate 3 is fixed by pressing the support plate 2 with the locking screw. The adjustment is simple and convenient.

[0031] The connecting plate 7 has an alignment port 11 for observing the scale 8, which allows personnel to take readings through the alignment port 11.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
