Description

Technical Field

[0001] The present invention relates to the technical field of slope measurement, and particularly relates to a slope measurement device for construction engineering. Background Art

[0002] There are mainly two methods for measuring slope: the leveling method and the instrument measurement method.

[0003] The leveling method is a relatively simple and accurate method, suitable for slope measurement in a small range. Its principle is based on the reference of the horizontal plane. The starting point and the ending point of the slope are selected, and a leveling staff is set up at the starting point to ensure that the leveling staff is horizontal. Then, a leveling staff is also set up at the ending point and ensured to be in the same horizontal plane as the leveling staff at the starting point. A measuring tool is used to measure the height difference and the horizontal distance between the starting point and the ending point, and the slope is calculated based on the height difference and the horizontal distance.

[0004] In actual operation, it is necessary to ensure the accuracy and stability of the leveling staff, and at the same time, try to avoid external interference during measurement. This method is applicable to various environments, whether it is flat or rough terrain, as long as stable support points and appropriate measurement distances can be found.

[0005] In construction engineering, slope measurement is a key link to ensure construction quality. When using the leveling method for slope measurement, when encountering rough terrain, if stable support points and appropriate measurement distances cannot be found, it will cause difficulties in slope measurement. In addition, although the traditional leveling method has high accuracy, it is complex in operation and low in efficiency. And the existing electronic slope meters have problems such as high price and single function. Therefore, it is of great practical significance to design a slope measurement device based on physical sensors and the leveling method. Summary of the Invention

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Refer to Figure 1 and Figure 2 , a slope measuring device for construction engineering. In order to be able to measure the slope even when a stable support point and a suitable measurement distance cannot be found, an installation base, a horizontal bubble tube 4, and a slope measuring mechanism are provided here. The installation base includes a cross pad frame 1, a slope top pointing component 2, and a lifting control frame 3. The cross pad frame 1 is an adjustable cross plate frame. The slope top pointing component 2 is arranged at one end of the cross pad frame 1, and the lifting control frame 3 is arranged at the center of the cross pad frame 1 and is perpendicular to the cross pad frame 1;

[0036] The horizontal bubble tube 4 is arranged at the center of the end frame of the lifting control frame 3. The slope measuring mechanism includes a pendulum measuring assembly 5 and a fixed-distance sensing assembly 6. The pendulum measuring assembly 5 is arranged on one side of the end frame of the lifting control frame 3;

[0037] The pendulum measuring assembly 5 includes a basic fixed frame 51 and a telescopic pendulum frame 52. The basic fixed frame 51 is fixedly arranged on one side of the end frame of the lifting control frame 3. The telescopic pendulum frame 52 is rotatably installed on one side of the end frame of the lifting control frame 3. Moreover, the basic fixed frame 51, the telescopic pendulum frame 52, and the horizontal bubble tube 4 rotate based on the same axis. The fixed-distance sensing assembly 6 is arranged at the bottom ends of the basic fixed frame 51 and the telescopic pendulum frame 52 to measure the distance between the ends of the basic fixed frame 51 and the telescopic pendulum frame 52.

[0038] As Figure 2 shown, the lifting control frame 3 includes a lifting base 31 and a placement cross plate 32. The lifting base 31 is arranged at the center of the cross cushion frame 1. The placement cross plate 32 is arranged at the lifting end of the lifting base 31, and the placement cross plate 32 is parallel to the cross cushion frame 1. A mounting long slot is opened at the center of the plate body of the placement cross plate 32. The horizontal bubble tube 4 is arranged inside the mounting long slot. The pendulum measuring assembly 5 is arranged on one side of the plate body of the placement cross plate 32, and the pendulum measuring assembly 5 rotates coaxially with the horizontal bubble tube 4. When the cross cushion frame 1 is arranged along the slope surface, the placement cross plate 32 can be parallel to the slope surface. At this time, it is convenient for the horizontal bubble tube 4 and the pendulum measuring assembly 5 on the placement cross plate 32 to determine the inclination angle of the slope surface and perform distance conversion.

[0039] The lifting base 31 includes multiple sections of lifting plate bodies, and the multiple sections of plate bodies of the lifting base 31 are tightly connected, so that the lifting base 31 can be controlled to expand and contract, thereby adjusting the distance between the placement cross plate 32 and other measuring structures on the placement cross plate 32 and the cross cushion frame 1. Moreover, when the lifting base 31 is shortened to the shortest, the bottom end of the basic fixed frame 51 and the pointing part of the slope top pointing assembly 2 at the end of the cross cushion frame 1 are in the same plane.

[0040] As Figure 3 shown, the horizontal bubble tube 4 includes a bubble tube main body 41 and a rotating base shaft 42. The rotating base shaft 42 is arranged on the inner side wall of the mounting long slot at the center of the placement cross plate 32. The center of the bubble tube main body 41 is arranged on the rotating base shaft 42, so that when the entire placement cross plate 32 is inclined and arranged on the slope along with the cross cushion frame 1, the bubble tube main body 41 can remain horizontal under the rotation of the rotating base shaft 42, forming a horizontal reference point to help confirm the horizontal plane.

[0041] As Figure 5 and Figure 6As shown in the figure, the base fixed frame 51 includes a stationary fixed frame 511 and a bottom contact cushion block 512. The stationary fixed frame 511 is arranged on one side of the placement cross plate 32 through a fixed shaft body. The bottom contact cushion block 512 is fixedly arranged at the bottom end of the stationary fixed frame 511, and the bottom end of the bottom contact cushion block 512 is a plane.

[0042] The telescopic pendulum frame 52 includes a telescopic frame body and a counterweight bottom block arranged at the bottom end of the telescopic frame body. Among them, the telescopic frame body is a multi-section telescopic metal frame body, and the end of the telescopic frame body is connected to the fixed shaft body where the stationary fixed frame 511 is connected to the placement cross plate 32. The bottom end of the counterweight bottom block is an arc edge;

[0043] Among them, the end of the telescopic frame body of the telescopic pendulum frame 52 is rotatably installed on the fixed shaft body where the stationary fixed frame 511 is connected to the placement cross plate 32 through a low-friction bearing, and an angle scale for reading is arranged at the joint where the low-friction bearing fits with the placement cross plate 32, so that the telescopic pendulum frame 52 can maintain a vertical state under the action of gravity, and the angle between the base fixed frame 51 and the telescopic pendulum frame 52 can be obtained through the angle scale.

[0044] As Figure 5 shown, the fixed-distance sensing component 6 includes a positioning cross beam 61 and a displacement sensor 62. The positioning cross beam 61 is arranged at the bottom end of the bottom contact cushion block 512, and the displacement sensor 62 is arranged at the bottom end of the counterweight bottom block of the telescopic pendulum frame 52, and the displacement sensor 62 fits with the positioning cross beam 61;

[0045] Among them, the positioning cross beam 61 is parallel to the bottom end of the bottom contact cushion block 512, and the displacement sensor 62 is parallel to the bottom end of the counterweight bottom block of the telescopic pendulum frame 52, so that when the counterweight bottom block of the telescopic pendulum frame 52 rotates and moves away from the bottom contact cushion block 512, the displacement sensor 62 can measure the distance between the counterweight bottom block and the bottom contact cushion block 512.

[0046] As Figure 7 and Figure 8 shown, it should be clear that for the general slope calculation, it is carried out through the horizontal length and vertical width of the slope. As Figure 7 and Figure 8 shown, the slope I = vertical height H / horizontal length L, and the slope is obtained. Since the stationary fixed frame 511 and the bottom contact cushion block 512 are perpendicular to the slope surface, when the telescopic pendulum frame 52 maintains a vertical state under the action of gravity, the distance h between the bottom counterweight bottom block of the telescopic pendulum frame 52 and the bottom contact cushion block 512 is equivalent to the vertical height H at this time, and the height value l of the stationary fixed frame 511 and the bottom contact cushion block 512 is equivalent to the horizontal length L. At this time, conversion can be carried out to obtain the slope.

[0047] The slope obtained through this conversion method can perform equivalent conversion and quickly calculate the slope in the case where there is no suitable measurement distance on the slope surface.

[0048] AsFigure 4 As shown, the cross-shaped pad holder 1 includes a transverse backing plate 101 and a longitudinal backing plate 102. Both the transverse backing plate 101 and the longitudinal backing plate 102 are metal backing plates, and the longitudinal backing plate 102 is tightly inserted into the center of the transverse backing plate 101, making the entire cross-shaped pad holder 1 in an adjustable state in terms of transverse length and longitudinal length. The pointing end of the slope top pointing component 2 is in the same plane as the transverse backing plate 101. It should be noted that the longitudinal backing plate 102 can be pulled out from the transverse backing plate 101, so that the slope can be placed solely through the transverse backing plate 101 to adapt to the slope.

[0049] As Figure 8 shown, the slope top pointing component 2 includes a laser pointing device 21 and an adjustable pad holder 22. The laser pointing device 21 is arranged on one side of the transverse backing plate 101, and the adjustable pad holder 22 is arranged at the lower end of one side of the transverse backing plate 101;

[0050] Among them, the laser line emitted by the laser pointing device 21 is parallel to the transverse backing plate 101, and the laser line emitted by the laser pointing device 21 is in contact with the bottom of the bottom contact pad 512. When the entire device needs to be parallel to the slope, the laser line emitted by the laser pointing device 21 can be used to point to the slope top in a straight line. At this time, the transverse backing plate 101 and the bottom contact pad 512 can be regarded as parallel to the slope.

[0051] As Figure 8 shown, the adjustable pad holder 22 includes a regulating component 221 and a bottom contact pad holder 222. The regulating component 221 is fixedly arranged on the transverse backing plate 101, and the moving end of the regulating component 221 is slidably installed on the plate body of the transverse backing plate 101. Four bottom contact pad holders 222 are arranged in a group below the moving end of the regulating component 221. The bottom contact pad holder 222 is a telescopic pad holder, and the regulating component 221 is a device pushed by an electric push rod. By controlling the positions of the moving end and the bottom contact pad holder 222 below the transverse backing plate 101, a support structure at different points can be formed on the undulating slope, so that the cross-shaped pad holder 1 is parallel to the slope, the laser line emitted by the laser pointing device 21 can point to the slope top, and a basis parallel to the slope is formed for the measuring structure above the cross-shaped pad holder 1.

[0052] It should be noted that, as Figure 8 shown, through the telescoping of the bottom contact pad holder 222 and the adjustment of the position of the bottom contact pad holder 222 on the transverse backing plate 101 by the regulating component 221, when the transverse backing plate 101 fits the bottom end of the slope, the entire cross-shaped pad holder 1 and the measuring device on the cross-shaped pad holder 1 can be kept parallel to the slope, so that the entire measuring device can be quickly and parallelly placed without a stable support point, facilitating subsequent calculation of the slope.

[0053] Working principle: Make one end of the horizontal backing plate 101 fit against the bottom end of the slope to be measured, and make the entire cross-shaped pad frame 1 fit on the slope and parallel to the slope. If the slope has undulations, the length of the bottom-touching pad frame 222 can be adjusted, and the position of the regulating member 221 and the bottom-touching pad frame 222 on the horizontal backing plate 101 can be adjusted to make the bottom end of the bottom-touching pad frame 222 touch the undulating part. Finally, make the laser line emitted by the laser pointing member 21 at the end of the horizontal backing plate 101 point to the top of the slope, so that the entire cross-shaped pad frame 1 is parallel to the straight line between the head and tail points of the slope. At this time, the lifting base 31 will be perpendicular to the slope with the placement of the cross-shaped pad frame 1, and the placement cross plate 32 will be parallel to the slope. The bubble tube body 41 can be kept horizontal under the rotation of the rotating basic shaft 42 to form a horizontal reference point to help confirm the horizontal plane. At this time, the fixed frame 511 on the placement cross plate 32 will be perpendicular to the slope. Adjust the multi-section plates of the lifting base 31 to be shortened to the shortest. At this time, the bottom-touching pad block 512 at the bottom of the fixed frame 511 fits against the slope, and the telescopic pendulum frame 52 will remain vertical under the action of gravity. At this time, adjust the length of the telescopic pendulum frame 52 to make the counterweight bottom block at the bottom of the telescopic pendulum frame 52 also fit against the slope. Measure the distance between the counterweight bottom block and the bottom-touching pad block 512 through the displacement sensor 62. At this time, the slope can be obtained by dividing the obtained distance value by the height values of the fixed frame 511 and the bottom-touching pad block 512, so as to quickly obtain the slope of the entire slope. It can quickly calculate the slope of the slope without a suitable support pad and the measurement of distance.
