Description

Technical Field

[0001] The utility model relates to the technical field of roadbed design, in particular to a slope measuring device for roadbed design. Background Art

[0002] The roadbed slope refers to the inclined surface connecting the ground on both sides of the roadbed cross section. The construction quality of the slope has a great impact on the stability of the roadbed. Therefore, it is necessary to measure parameters such as the angle and height of the slope during roadbed design.

[0003] In order to measure the above parameters, the Chinese utility model patent with authorization announcement number CN217953473U discloses a slope measuring device for highway roadbed design, which includes a No. 1 ruler, a No. 2 ruler movably connected to the bottom end of the No. 1 ruler, a horizontal angle scale protractor fixedly connected to the inside of the No. 2 ruler, a bubble level fixedly connected to the upper surface of the top of the No. 1 ruler and a sliding horizontal infrared locator, and a sliding horizontal infrared locator fixedly connected to the outer edge of the top of the No. 1 ruler. Through the tip of the bottom of the No. 1 ruler and the bubble level, the device can be placed vertically on the ground. By fitting the No. 2 ruler with the measured slope and adjusting the horizontal angle scale protractor on the No. 2 ruler, the slope angle can be directly observed. By adjusting the sliding horizontal infrared locator so that the infrared radiation is on the angle scale line of the No. 2 ruler, the observed angle scale can be made more accurate.

[0004] Although the above patent can measure the height and angle of the slope, after the No. 2 ruler is stored in the cavity of the No. 1 ruler, the No. 2 ruler cannot be limited. As a result, when the measuring device is transferred, the No. 2 ruler can easily rotate freely out of the No. 1 ruler, causing the No. 2 ruler to break. At the same time, the length of the No. 2 ruler is limited, resulting in certain limitations in the measurement of the slope width by the No. 2 ruler. Utility Model Content

[0028] Place the support rod 1 vertically on the ground on one side of the slope, then open the locking piece and rotate the measuring rod 2 so that the measuring rod 2 fits the slope surface. At this time, record the angle between the measuring rod 2 and the support rod 1, and record the position of the slope width on the measuring rod 2 to facilitate calculating the angle and height parameters of the slope. If the slope width is large, the rotating operating part drives the extension rod 3 to move outward from the measuring rod 2 through the transmission part, so that the total length of the measuring rod 2 and the extension rod 3 can accurately measure the slope width; the operation is simple and convenient, the support rod 1 can stably store the measuring rod 2 and the extension rod 3, and can adjust the total length of the measuring rod 2 and the extension rod 3 according to the actual width of the slope, so that the measuring device has good measurement flexibility and good adaptability.

[0032] The operating member includes a knob 42 rotatably arranged on one side of the measuring rod 2 , and one end of the measuring rod 2 freely passes through the measuring rod 2 and is coaxially fixedly connected to the knob 42 .

[0033] The rotating knob 42 drives the rotating rod 4 to rotate. During the rotation of the rotating rod 4, the gear 41 and the plurality of assembly teeth 33 drive the extension rod 3 to move between the inner and outer sides of the measuring rod 2 to change the total length of the measuring rod 2 and the extension rod 3.

[0034] like Figure 2-3 As shown, according to another embodiment of the present invention, the slope measuring device for roadbed design is further optimized in terms of the limit member it includes, a cavity 12 is opened in the side wall of one end of the rotating groove 11, and the limit member includes a pull rod 13 that slides through the side wall of the rotating groove 11 and the cavity 12, a limit plate 14 is fixedly sleeved on the pull rod 13, and a spring 15 is elastically connected between the limit plate 14 and the side wall of the cavity 12 away from the rotating groove 11; wherein the end of the pull rod 13 located in the rotating groove 11 is a wedge-shaped structure, so that when the pull rod 13 is against the side wall of the measuring rod 2, the pull rod 13 can move out of the rotating groove 11 and compress the spring 15, and when the measuring rod 2 is rotated into the rotating groove 11, the pull rod 13 is reset by the elastic action of the spring 15, and the measuring rod 2 is limited.

[0035] like Figure 1-2 As shown, according to another embodiment of the present invention, in the slope measuring device for roadbed design, preferably, a fixing plate 32 is fixedly installed on one end of the extension rod 3 located outside the measuring rod 2.

[0036] like Figure 1 As shown, according to another embodiment of the present invention, in the slope measuring device for roadbed design, preferably, the side wall of the support rod 1 is provided with an angle scale 6 arranged in a circular trajectory, and a pointer 5 is coaxially fixedly installed after one end of the rotating shaft 21 passes through the rotating groove 11, and the pointer 5 is coaxially rotated and arranged in the angle scale 6; rotating the measuring rod 2 can drive the pointer 5 to rotate synchronously, and the accurate rotation angle can be obtained through the angle scale 6.

[0038] The operating principle of the present invention is as follows: when the present invention is used, the tip of the support rod 1 is inserted into the soil on one side of the slope, and the support rod 1 is supported stably according to the circular level 7, and then the pull rod 13 is pulled to make the pull rod 13 disengage from the limit of the measuring rod 2, and then the measuring rod 2 is rotated until it fits the slope surface. At this time, the angle scale 6 pointed by the pointer 5 is recorded, and the position of the width of the slope on the measuring rod 2 is recorded at the same time, so as to calculate the angle and height parameters of the slope. If the width of the slope is large, the butterfly bolt 43 is loosened, and then the knob 42 is turned to drive the rotating rod 4 to rotate. During the rotation of the rotating rod 4, the gear 41 and several The transmission of the assembly teeth 33 drives the extension rod 3 to move outward from the measuring rod 2, so that the total length of the measuring rod 2 and the extension rod 3 can accurately measure the width of the slope; after the measurement is completed, the knob 42 is rotated in the opposite direction to retract the extension rod 3 into the measuring rod 2, and then the butterfly bolt 43 is tightened to fix the rotating rod 4, and then the measuring rod 2 is rotated toward the rotating groove 11, so that the pull rod 13 is against the side wall of the measuring rod 2, and the pull rod 13 moves outward from the rotating groove 11 and compresses the spring 15. When the measuring rod 2 is rotated into the rotating groove 11, the elastic action of the spring 15 resets the pull rod 13 and limits the measuring rod 2 to complete the storage of the measuring rod 2.
