[0017] Please refer toFigure 1 、 Figure 2 、 Figure 3 and Figure 4 The patent provides a technical solution: a kind of earth excavation measuring device, including fixed plate 1, fixed plate 1 is two, the top inner side of fixed plate 1 is equipped with chute 2, slidingly installed with sliding block 3 in chute 2, fixedly installed with cross rail 4 between two sliding blocks 3, slidingly installed with sliding ring 5 on the side wall of cross rail 4, the bottom of sliding ring 5 is fixedly installed with adjusting rod 6, the bottom end of adjusting rod 6 is fixedly installed with box 7, the bottom of box 7 is equipped with sliding hole 8, the inner side wall top wall of box 7 is fixedly installed with first fixed contact 9, the inside left side wall of box 7 is installed with bulb and battery, the inside right side wall of box 7 is fixedly installed with connecting rod 10, the left end of connecting rod 10 is fixedly installed with second fixed contact 11, the inside right side wall of box 7 is installed with bulb and battery, the inner side wall of sliding hole 8 is slidingly installed with vertical rod 12, the top end of vertical rod 12 is installed with moving contact 13 on the left and right sides, and the bottom end of vertical rod 12 is installed with gyro wheel 14.

[0018] As Figure 2 indicated, the left moving contact 13 is located directly below the first fixed contact 9, and the spacing can be the protrusion range of the foundation pit ground, such as 0.5 mm, and the right moving contact 13 is located directly above the second fixed contact 11, and the spacing is the recess range of the foundation pit ground, such as 0.5 mm.

[0019] The left moving contact 13 and the first fixed contact 9 are connected in series with the left bulb and battery through wires, and the right moving contact 13 and the second fixed contact 11 are connected in series with the right bulb and battery through wires.

[0020] Specifically, adjusting rod 6 includes screw rod 15, square rod 16 and square tube 18, the side wall of cross rail 4 is provided with rectangular hole 19, the inner side wall of sliding ring 5 is provided with through hole 20 at both ends, the top of sliding ring 5 is provided with circular groove 21, the inner side wall of circular groove 21 is fixedly installed with bearing 22, the side wall of screw rod 15 is fixedly installed on the inner side wall of the inner ring of bearing 22, the bottom end of screw rod 15 extends to the lower side of sliding ring 5 through rectangular hole 19 and through hole 20 in sequence, the top end of square rod 16 is provided with threaded groove 17, threaded groove 17 is screwed on screw rod 15, the bottom end of square rod 16 is fixedly installed on the top of box 7, the top of square tube 18 is fixedly installed on the bottom of sliding ring 5, and the inner side wall of square tube 18 is slidably fitted with the outer side wall of square rod 16.

[0021] By the inner side wall of square tube 18 and the outer side wall of square rod 16 being slidably fitted, the moving track of square rod 16 is limited, so that it can only move up and down, which is equivalent to the limiting mechanism in the screw mechanism.

[0022] When the position of the roller 14 needs to be adjusted forward and backward, the screw rod 15 can be rotated to drive the square rod 16 and the box body 7 to move upward by a distance, and then the vertical rod 12 is moved upward to make the roller 14 away from the ground, avoiding the friction of the roller 14 contacting the ground in the foundation pit and making the movement of the roller 14 inconvenient.

[0023] Specifically, the top of the box body 7 is embedded with a transparent observation window 23.

[0024] The transparent observation window 23 is convenient for the staff to observe the two bulbs in the box body 7.

[0025] Specifically, the left and right sides of the slip ring 5 are fixedly installed with pull lines 24.

[0026] The pull lines 24 are convenient for the staff on the foundation pit to pull the left and right sides of the slip ring 5.

[0027] Specifically, the fixed plate 1 is provided with a mounting hole, and the mounting hole is provided with a bolt 25.

[0028] The bolt 25 is convenient for fixing the fixed plate 1 to the ground and placing the movement.

[0029] Specifically, the left side of the left slide block 3 is integrally formed with a plate body 26, the top of the plate body 26 is attached with a pressing plate 27, and the end of the left bolt 25 is tightly attached to the top of the pressing plate 27.

[0030] The front and back lengths of the pressing plate 27 match the front and back lengths of the fixed plate 1 (the front and back lengths of the fixed plate 1 are slightly larger than the front and back lengths of the foundation pit), and after moving the slide block 3 forward and backward, the position of the slide block 3 can be fixed by tightening the bolt 25, pressing the pressing plate 27 on the bolt 25, and then pressing the plate body 26 on the pressing plate 27.

[0031] Working principle: as shown in the figure, Figure 1 The staff on the ground pulls the left pull line 24 to the left, drives the slip ring 5 to move to the left, and if the ground in the foundation pit is convex, the vertical rod 12 will be moved upward to make the left moving contact 13 contact with the first fixed contact 9, so that the left bulb is lit, and if the ground in the foundation pit is concave, the vertical rod 12 will be moved downward to make the right moving contact 13 contact with the second fixed contact 11, so that the right bulb is lit.

[0032] The wire on the moving contact 13 is long, which is convenient for the position of the moving contact 13 to move.
