Description

Technical Field

[0001] The invention relates to a measuring device, in particular to a simple side slope ratio measuring device, and belongs to the technical field of side slope construction. Background Art

[0002] Generally speaking, with the continuous acceleration of construction projects in my country, the slope ratio of the foundation pit is an important parameter in engineering construction, especially in foundation pit projects with slope excavation, which is related to the safety of the foundation pit. Slope ratios (such as 1:1 or 1:0.5) are used in engineering to indicate the steepness of the slope. The slope ratio refers to the ratio of the vertical distance H to the horizontal distance L. In actual construction, it is often necessary to measure the slope ratio of the slope. However, traditional measurement methods are time-consuming and labor-intensive. Due to the complexity of the operation, few people are willing to re-measure frequently during the slope excavation process, which may result in the slope ratio not meeting the design requirements.

[0003] Most of the existing slope ratio measuring devices are triangular structures, including vertical rods, horizontal rods and diagonal rods. The vertical rods and horizontal rods are vertically connected, and the two ends of the diagonal rods are respectively connected to the vertical rods and the horizontal rods. A positioning rod is set through the horizontal rod, and the horizontality of the slope ratio measuring device is adjusted by the positioning rod. At the same time, there are basically no direct measurement tools for existing slope ratio measurement. In actual use, the height difference between the top and bottom of the slope and the plane position spacing are collected and calculated using a total station. The process is cumbersome and inconvenient to use. The measurement result cannot directly reflect the slope ratio and needs to be calculated.

[0004] At present, a Chinese invention patent with the announcement number CN214893271 U discloses a slope ratio measuring device, which belongs to the technical field of slope measurement in construction projects. The slope ratio measuring device includes a horizontal rod, a vertical rod, and an oblique rod. The two ends of the oblique rod are hinged to one end of the horizontal rod and the vertical rod respectively. The other end of the horizontal rod is connected to the vertical rod by a second locking bolt. The oblique rod includes a sleeve rod and an insertion rod. The sleeve rod and the insertion rod are connected by a sleeve and a first locking bolt is provided. A horizontal bubble tube is provided on the horizontal rod. A "U"-shaped connecting block is hingedly installed on the outer side of the hinged end of the oblique rod and the vertical rod by a connecting bolt. A positioning anchor is provided at the bottom of the connecting block. However, the slope ratio measuring device has the problem that when it is used, the vertical rod must be anchored to the ground at the measurement position by a positioning anchor. The use process is cumbersome and inconvenient. The measurement result cannot directly reflect the slope ratio and needs to be obtained after calculation.

[0005] Therefore, the key to solving the above technical problems is to develop a simple slope ratio measuring device that is easy to operate and can read quickly. Summary of the Invention

[0093] Further, as Figure 6 shown, the connection component 5 includes:

[0099] In the present invention, the limit locking member 54 is arranged to pass through the lower part of the connecting member 52. When the limit locking member 54 is tightened, the limit locking member 54 is tightly connected to the non-transparent cover end of the shell 12, thereby limiting the rotation of the connecting member 52 and limiting the rotation of the second gear 53; a gap is provided between the limit locking member 54 and the second gear 53; the limit locking member 54 includes a limit locking knob and a screw connected to one end of the limit locking knob, and the screw is threadedly connected to the locking threaded hole at the lower part of the connecting member 52; the limit locking knob is a cylinder or a cone.

[0104] In summary, a more specific embodiment of the present invention is:

[0105] Before using the simple slope ratio measuring device of the above-mentioned design structure, it is necessary to manufacture and install it as a backup.

[0106] The device has a simple structure and no complicated mechanical structure. It can be manufactured in a general factory according to the design drawing of the device. After the device is manufactured according to the design drawing requirements, it can be installed as a spare according to needs.

[0107] The specific installation steps are:

[0108] After the device is processed in the factory, the operator only needs to carry the device to the designated construction site by hand or with corresponding transport equipment for use.

[0109] The specific steps are:

[0110] First, take the slope ratio measuring device 1 to the slope position to be measured;

[0111] Then, the movable rod 62 is pulled out through the connecting block 63;

[0112] Then, loosen the limit locking member 54 to allow the telescopic measuring rod 6 to rotate freely;

[0113] Next, place the retractable measuring rod 6 against the slope to be measured, and observe the level bubble 4 with your eyes to place the handle 3 in a horizontal state;

[0114] Finally, tighten the limit locking member 54 to fix the telescopic measuring rod 6, and read the reading of the indicator needle 11 on the dial 13.

[0115] As time goes by, when all construction work is completed and the present invention is no longer needed, the operator only needs to dismantle the present invention. When dismantling:

[0116] First, the operator loosens the limit locking member 54 to allow the telescopic measuring rod 6 to rotate freely;

[0117] Then, rotate the telescopic measuring rod 6 to a suitable position;

[0118] Next, tighten the limit locking member 54 to fix the telescopic measuring rod 6;

[0119] Finally, the movable rod 62 can be folded up through the connecting block 63. At the same time, after cleaning and repairing the various components of the present invention, they are transported to the designated tool storage warehouse for storage again by manual labor or corresponding transportation equipment, so as to be used in the next cycle.

[0120] During the entire operation process described above, the second gear 53 rotates 90°, which drives the first gear 2 to rotate 360°.

[0121] The circumference R of the second gear 53 is exactly 4 times the circumference r of the first gear 2. The slope ratio range is between 1:0 and 1:∞. The corresponding rotation angle of the second gear 53 is between 0° and 90°, and the corresponding rotation angle of the first gear 2 is between 0° and 360°.

[0122] For example, if the slope ratio of a certain slope is 1:n, during measurement, the second gear 53 rotates by an angle of arctan 1:n, and the corresponding angle of rotation of the first gear 2 is 4×arctan 1:n. This means that the pointer connected to the first gear 2 also rotates by 4×arctan 1:n. During manufacturing of the device, the slope ratio value can be calculated and marked at the corresponding position. The slope ratio scale lines and the corresponding scale / slope ratio values ​​on the dial 13 are calculated by calculating the gear rotation angle and then back-calculating them on the dial.

[0123] Taking a slope with a slope ratio of 1:1 as an example, when measuring this slope, the angle of rotation of the second gear 53 is arctan1:1 = 45°. Since the circumference R of the second gear 53 is exactly 4 times the circumference r of the first gear 2, the angle of rotation of the first gear 2 caused by the second gear 53 is 4×arctan1:1 = 180°. That is, the pointer connected to the first gear 2 also rotates 180°. Therefore, the position where the pointer rotates 180° corresponds to the position with a slope ratio of 1:1.

[0124] Comparative analysis with traditional methods

[0125]

[0126]

[0127] In summary, the present invention is simple to measure, easy to carry, saves time and effort, and can measure the slope ratios of different slopes. In actual use, only one device of the present invention needs to be carried.
