Description

Technical Field

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

[0002] During highway construction, it is necessary to measure the slope for acceptance. A slope measuring instrument is needed for measurement. Currently, most slope measurement methods on the market use pendulum-type slope measuring instruments, and there will be certain errors when using the large pendulum.

[0003] A Chinese patent (authorization announcement number: CN117647228A) proposes a slope measuring device for highway construction, including a frame, a measuring mechanism fixed to the top inner wall of the frame, the measuring mechanism is used to measure the angle of the slope, the upper surface of the frame is provided with a connecting plate, the connecting plate can be connected to a traction member for climbing operations, both sides of the frame are provided with an adjustment mechanism and a driving wheel, the adjustment mechanism can adjust the distance between the driving wheel and the frame, and a weight block is fixedly connected to the bottom inner wall of the frame. The present invention can photograph the road section condition in front of the equipment, adjust the distance between the driving wheel and the frame, so that the driving wheel can avoid obstacles when the equipment climbs the slope, simulate the inclination of the vehicle itself when the vehicle enters and exits, and judge whether it meets the safety range value. At the same time, it can detect the length of the slope, the slope at different positions on the slope, and the curvature of the slope itself. It has a multifunctional detection function and an integrated detection effect, and is practical.

[0004] When the above scheme is used, since only a short distance of the slope can be measured, the surface of the slope may be uneven, which will cause certain errors when the above scheme is used. In order to solve the problem of certain errors when used, we propose a highway construction slope measuring device. Utility Model Content

[0014] Beneficial Effects

[0015] The utility model provides a road construction slope measuring device. Compared with the prior art, it has the following beneficial effects:

[0016] When using the highway construction slope measuring device, one only needs to hold the handle, use a spirit level to keep the installation frame on a horizontal plane, and abut the second abutment movable bar against the junction of the slope and the ground. At this time, the installation frame is pressed downward, and when the first abutment movable bar on the slope is lifted up, the lifted first abutment movable bar will push the corresponding second elastic telescopic arm. At this time, the second elastic telescopic arm will rotate, and the second elastic telescopic arm will pull the first elastic telescopic arm when rotating. The angle between the two groups of second elastic telescopic arms can be measured by a protractor, so as to measure the slope at this time. Since the distance between several first abutment movable bars is far, longer slopes can be measured. BRIEF DESCRIPTION OF THE DRAWINGS

A pulley 15 is rotatably connected to the outer wall of the mounting frame 1, and the outer wall of the pulley 15 is wrapped with sponge, which can reduce damage to the reset pull wire 18. The pulley 15 can also avoid friction between the reset pull wire 18 and the outer wall of the mounting frame 1.

[0029] Working principle: When in use, you only need to hold the handle 4, use the level 5 to keep the mounting frame 1 on the horizontal plane, and abut the second abutting movable bar 26 against the junction of the slope and the ground. At this time, press the mounting frame 1 downward. When the first abutting movable bar 2 on the slope is lifted up, the lifted first abutting movable bar 2 will push the corresponding second elastic telescopic arm 7. At this time, the second elastic telescopic arm 7 will rotate. When the second elastic telescopic arm 7 rotates, it will pull the first elastic telescopic arm 6.

It is worth noting that this kind of slope can only be measured on the symmetrical curved slope;

[0031] When the first abutting movable bar 2 is pushed out, the first abutting movable bar 2 will pull the reset wire 18, and the reset wire 18 will drive the recovery wire wheel 17 to rotate, and the recovery wire wheel 17 drives the clamping annular block 21 to rotate together through the rotating disk 16, and the clamping annular block 21 drives the reset torsion spring 20 to store force through the clamping piece 22. When the first abutting movable bar 2 leaves the abutment with the curved slope, the reset torsion spring 20 releases the stored force, and the reset torsion spring 20 drives the clamping annular block 21 to reset and rotate through the clamping piece 22, and the clamping annular block 21 drives the recovery wire wheel 17 to rotate through the rotating disk 16, and the recovery wire wheel 17 resets the reset wire 18, and the reset wire 18 is pulled by the recovery wire wheel 17, and the reset wire 18 drives the first abutting movable bar 2 to reset.
