Description

Technical Field

[0001] The utility model belongs to the field of slope measurement, in particular to a visual slope measurement device. Background Art

[0002] There are many kinds of slope control methods in the construction process of earthwork engineering. In particular, the majority of construction workers have many ways to control the slope in basic construction. The traditional methods in the past include step excavation method, sample frame method, distance vertical line method, and the tools for controlling the slope include slope ruler, slope inspection board, etc. However, these methods are more troublesome to operate, especially when detecting the slope of the project. For example: to measure the slope by the distance vertical line method, first measure the horizontal distance of multiple slopes, and then calculate the slope ratio of the slope. When measuring, it cannot be used when the wind is strong, because the wind will blow the tape measure, causing measurement errors and making the calculated slope ratio inaccurate. Therefore, the distance vertical line method is limited by certain external conditions, and the measurement speed is slow and difficult to master; the slope ruler is also limited by certain conditions when measuring the slope. What kind of slope ruler can only measure what kind of slope.

[0003] Secondly, most current projects have multi-level slopes with large drop heights. Therefore, in earthwork construction, it is very important to control the slope standard. Whether it is the filling construction of embankments (dams), canal embankments or the foundation construction of other types of buildings, it is very important to strictly control the slope. Otherwise, it will affect the quality of the project, and in serious cases, it will cause rework and waste manpower and material resources. Utility Model Content

[0023] See also Figure 1-3 The present embodiment is described as a visual slope measuring device, which includes a main body, a scale pointer 2, a dial 3 and a laser 7. The dial 3 is arranged on one side of the main body, and an angle scale is arranged on the dial 3. A rotating ring is rotatably connected to the main body, and the scale pointer 2 and the laser 7 are arranged on both sides of the rotating ring. The laser 7 is coaxially and oriented with the scale pointer 2, and the scale pointer 2 corresponds to the position of the dial 3.

[0024] When in use, place the visual slope measuring device at the reference point at the top or foot of the measured slope, adjust the scale pointer 2 to the designed slope according to the dial 3, and during the adjustment process, the laser 7 and the scale pointer 2 rotate synchronously on the same axis and in the same direction under the drive of the rotating ring. After adjusting to the designed slope, turn on the laser 7 to project a virtual reference line through the laser, measure the vertical distance between the reference line and the slope to be measured, and the thickness of the slope to be measured can be directly obtained. The construction can be controlled by measuring the vertical distance from the virtual reference line to the surface to be measured.

[0025] In this embodiment, the body is rotatably connected with a pointer adjuster 1, and the pointer adjuster 1 is connected to a rotating ring. The rotating ring is driven to rotate by rotating the pointer adjuster 1, and the rotation of the rotating ring drives the scale pointer 2 and the laser 7 to rotate synchronously, coaxially and in the same direction. Preferably, the pointer adjuster 1 is connected to the rotating ring through a gear set, and the pointer adjuster 1 drives the rotating ring to rotate through the meshing transmission relationship between the gears, thereby driving the rotation of the scale pointer 2 and the laser 7. A ground plug bracket 6 is provided at the bottom of the body. Preferably, the ground plug bracket 6 is a telescopic ground plug bracket, and the body and the telescopic ground plug bracket are connected by a bolt interface. A level 5 is provided on the inner ring of the rotating ring, and the horizontal state of the visual slope measuring device is judged by the level 5. Preferably, the level 5 is a tube level. A grip handle 4 is provided on the body for easy operation, and the body is preferably made of plastic.

[0026] When using this embodiment, first, place the telescopic ground plug bracket at the measured reference point at the top of the slope or the foot of the slope, then install the visual slope measuring device on the telescopic ground plug bracket, and tighten the bolt interface between the telescopic ground plug bracket and the body. Then, turn the pointer adjuster 1 to rotate the scale pointer 2 and the laser 7 to the designed slope, and turn on the laser 7; finally, control the construction by measuring the vertical distance from the laser reference line emitted by the laser 7 to the surface to be measured. If the theoretical vertical distance is greater than the measured value, it is an under-excavation state; if the theoretical vertical distance is less than the measured value, it is an over-excavation state.
