Description

Technical Field

[0001] The utility model relates to the technical field of highways, in particular to a highway slope ruler. Background Art

[0002] As a device specifically designed for highway construction, the core function of a slope gauge is to accurately collect slope data, providing crucial data support for highway construction. This device ensures that slope control during construction is based on accurate data, thereby improving the overall quality and safety of the project.

[0003] Chinese patent CN 208505294 U discloses a slope meter for highway engineering, the measurement principle of which mainly relies on the deflection angle of the gravity bob. Specifically, when the slope meter is placed on the slope to be measured, the gravity bob will deflect due to the slope of the slope, and its deflection angle represents the slope of the slope. However, in actual construction sites, environmental conditions are often harsh, including humidity, dust, and the possible presence of large amounts of sand and gravel. In such an environment, the rotating shaft components inside the slope meter are extremely susceptible to corrosion, such as rust or sand and gravel embedding. These factors may have a serious impact on the smooth rotation of the gravity bob, resulting in inflexible or stuck rotation. Once such problems occur in the rotating shaft, the deflection of the gravity bob will no longer accurately reflect the actual slope of the slope, thereby causing measurement deviations.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0026] like Figure 1-Figure 4 As shown, a road grade ruler includes a rectangular ruler body 100, a mounting slot is formed in the middle of the rectangular ruler body, a rotating shaft 2 is provided on each side of the mounting slot, a rotating disk 3 is rotatably connected between the two rotating shafts, and a locking mechanism 4 is provided on both sides of the mounting slot.

[0027] Furthermore, a raised rubber block 34 is provided in the installation slot, and the raised rubber block can abut against the rotating disk to limit the rotating disk from rotating around the rotating axis.

[0028] Furthermore, the rotating disk includes a disk body 31, a transparent disk surface 32 is installed on the top of the disk body, and an installation cavity is formed between the disk body and the transparent disk surface, and the installation cavity is filled with colored liquid.

[0029] The solution is refined, and the installation cavity is accurately filled with half of its volume of deionized water or special measuring liquid to reduce the impact of liquid impurities on measurement accuracy.

[0030] Specifically, when the rotating disk rotates to a vertical state, the liquid surface passes through the center point of the transparent disk surface, providing an intuitive reference for measurement.

[0031] Furthermore, the transparent disk is provided with a plurality of scales 33, which are engraved with laser technology to ensure that the scales are clearly readable for a long time and can maintain high-precision measurement even in harsh environments.

[0032] According to a refinement of the solution, the rotating disk can rotate around the rotating axis until it is perpendicular to the rectangular ruler.

[0033] The solution is refined. When the rotating disk is perpendicular to the rectangular ruler body, the rotating disk is clamped between the two clamping mechanisms.

[0034] Furthermore, the installation slot includes a semicircular slot 101 and a rectangular slot 102 . A semicircular slot is formed in the middle of the rectangular ruler body, and the end of the semicircular slot extends toward the edge of the rectangular ruler body to form a rectangular slot.

[0035] Furthermore, the edges of the rectangular notch are rounded.

[0036] In at least one embodiment, the locking mechanism includes a fixed block 41, a guide hole is formed in the middle of the fixed block, a guide rod 42 is slidably fitted in the guide hole, a locking block 45 is provided at one end of the guide rod close to the installation slot, a limiting plate 43 is provided at one end of the guide rod away from the installation slot, and a flexible spring 44 is provided between the limiting plate and the fixed block.

[0037] The solution is refined, and the flexible spring can drive the limiting plate to move in a direction close to the fixed block.

[0038] In at least one embodiment, a leveling mechanism 5 is provided at the end of the rectangular ruler body, and the leveling mechanism includes a sliding rod 52, with which a sliding plug hole that cooperates with the sliding rod is provided on the side wall of the rectangular ruler body, and a threaded sleeve 53 is provided at the end of the sliding rod, and a leveling bolt 54 is threadedly connected to the threaded sleeve.

[0040] To work, place the road grade gauge on the road surface whose slope is to be measured. Adjust the leveling mechanism to center the bubble in the T-shaped bubble level 104, ensuring the grade gauge is parallel to the road surface. If necessary, fine-tune the leveling bolts 54 for further adjustment.

[0041] Rotate the rotating disk 3 while observing the liquid level in the transparent disk 32. When the liquid level passes through the center point of the transparent disk, it indicates that the rotating disk is roughly perpendicular to the slope, and it is fixed with the locking mechanism 4. After ensuring that the rotating disk is stable, reconfirm that the bubble of the T-shaped bubble level 104 is still centered to ensure measurement accuracy.
