The knob 42 is installed above the first screw 43, and the lifting plate 45 is installed through a bearing below the first screw 43 and at a position inside the bottom box 41. A plurality of insert cones 44 are installed below the lifting plate 45, and the bottom box 41 and the shell 1 are connected via a lifting assembly 46.

[0024] By adopting the above technical solution, the staff can, when necessary, perform auxiliary fixation on the position of the device through the cooperation of the first screw rod 43 and the insert cone 44 and other structures, thereby reducing the possibility of accidental movement of the device.

[0025] Specifically, the shape and size of the inner cross section of the bottom box 41 are the same as the shape and size of the outer cross section of the lifting plate 45 .

[0026] By adopting the above technical solution, the device can ensure that the inner side of the bottom box 41 can be in close contact with the outer side of the lifting plate 45, thereby preventing the lifting plate 45 from rotating and deviating during movement, ensuring normal operation.

[0027] Specifically, the lifting assembly 46 includes a fixed frame 461, threaded holes 462, screws 463 and connecting columns 464.

A plurality of threaded holes 462 are provided on the side of the connecting column 464 away from the first screw 43, and a screw 463 is installed on the top of the fixed frame 461 through threads.

[0028] By adopting the above technical solution, the staff can adjust the height of the shell 1 and other structures by cooperating with the screws 463 and the connecting column 464 when necessary, so as to better meet the work needs in different situations.

[0029] When the present embodiment is used, when the device is needed to detect the slope during highway construction, the worker holds the rubber sleeve 8 outside the grip 7, carries the device and places it at the working position, and turns the knob 42 in the fixed lifting device 4, the knob 42 drives the first screw 43 to rotate, the first screw 43 is threadedly connected to the bottom box 41, the first screw 43 is bearing-connected to the lifting plate 45, and the outer side of the lifting plate 45 is close to the inner side of the bottom box 41, so the first screw 43 drives the lifting plate 45 to descend, and then inserts the cone 44 into the ground, and then the worker screws the lifting The screw 463 on the fixed frame 461 in the component 46 disengages it from the threaded hole 462 on the connecting column 464, and then pulls the shell 1 to make it and the connecting column 464 and other structures rise to the required height, and then rotates the screw 463 in the opposite direction to connect it with the corresponding threaded hole 462. Under the action of gravity, the counterweight ball component 3 is always facing downward, thereby driving the ring arrow component 2 to rotate a certain amount. The staff can judge the size of the slope through the scale pointed by the ring arrow component 2, and the staff can judge the other scale through the scale magnification component 6, and the work is completed.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the pressing anti-rotation device 5 includes a connecting shell 51, a rubber block 52, a connecting plate 53, a second screw 54 and a rotating plate 55. The connecting shell 51 is installed at the top of the shell 1 and located on the side of the scale magnification component 6 away from the grip 7. The second screw 54 is installed on the top of the connecting shell 51 through a thread, and the rotating plate 55 is installed above the second screw 54. The connecting plate 53 is installed below the second screw 54 and located on the inner side of the connecting shell 51 through a bearing, and the rubber block 52 is installed below the connecting plate 53.

[0032] By adopting the above technical solution, the staff can prevent the ring arrow assembly 2 from rotating when necessary through the cooperation of the rubber block 52 and the second screw 54, thereby preventing the scale it points to from changing, thereby better meeting the work needs in different situations.

[0033] Specifically, the shape and size of the inner cross section of the connection shell 51 are the same as the shape and size of the outer cross section of the connection plate 53 .

[0034] By adopting the above technical solution, the device can ensure that the inner side of the connecting shell 51 can be tightly attached to the outer side of the connecting plate 53, thereby preventing the connecting plate 53 from rotating and deviating during movement, and ensuring normal operation.

[0035] When this embodiment is in use, when the staff needs to prevent the ring arrow assembly 2 from rotating, the staff rotates and presses the rotating plate 55 in the anti-rotation device 5, and the rotating plate 55 drives the second screw 54 to rotate. The second screw 54 is threadedly connected to the connecting shell 51, and the second screw 54 is bearing-connected to the connecting plate 53. The outer side of the connecting plate 53 is close to the inner side of the connecting shell 51, so the second screw 54 drives the connecting plate 53 to descend, and then drives the rubber block 52 to press and fix the ring arrow assembly 2, thereby preventing it from rotating and preventing the scale it points to from changing, thereby better meeting the work needs in different situations.

[0036] The structure and principle of the shell 1 and its upper structure, the ring arrow assembly 2 composed of a ring, a triangular arrow, an iron block, a connecting plate, a level tube and a magnetic block, the counterweight ball assembly 3 composed of a fixed column and a counterweight ball, the scale magnification assembly 6 composed of a first angle scale line, a slip ring, a magnifying glass, a reference arrow, a slider, a screw and a rotating column, the grip 7, and the rubber sleeve 8 in the utility model have been disclosed in a highway slope detection device disclosed in Chinese patent application No. 202222666767.0. Its working principle is that the gravity of the counterweight ball will drive the ring to rotate until the counterweight ball is located on the ring. , at this time, the fixed column is in a vertical state, which prevents people from rotating the ring. No matter who or when the counterweight ball is used, it is always located directly below the ring, so that the result of each test is the same, ensuring the accuracy of each test result; turning the screw, the screw turns the slider to move up and down relative to the screw, so the slider will slide up and down inside the first slide groove, and the slider drives the slip ring and the magnifying glass to move up and down. People can observe the scale value on the first angle scale line pointed by the reference arrow through the magnifying glass from the upper side, avoiding people from bending over and tilting their heads to observe the test results, reducing the difficulty of people reading.

[0037] The working principle and use process of the utility model are as follows: when the device is needed to detect the slope during highway construction, the worker holds the rubber sleeve 8 outside the grip 7, carries the device and places it to the working position, and rotates the knob 42 in the fixed lifting device 4, and the knob 42 drives the first screw 43 to rotate, the first screw 43 is threadedly connected to the bottom box 41, the first screw 43 is bearing-connected to the lifting plate 45, and the outer side of the lifting plate 45 is close to the inner side of the bottom box 41, so the first screw 43 drives the lifting plate 45 to descend, and then inserts the cone 44 into the ground, and then the worker screws the screw 463 on the fixed frame 461 in the lifting assembly 46 to disengage it from the threaded hole 462 on the connecting column 464, and then pulls the shell 1 to make it and the connecting column 464 and other structures rise to the required height, and then reversely rotates the screw 463 to connect it with the corresponding threaded hole 462 Under the action of gravity, the counterweight ball assembly 3 is always facing downward, thereby driving the circular arrow assembly 2 to rotate to a certain extent. The staff can judge the size of the slope through the scale pointed by the circular arrow assembly 2, and the staff can judge another scale through the scale magnifying assembly 6, and the work is completed; when the staff needs to prevent the circular arrow assembly 2 from rotating, the staff rotates and presses the rotating plate 55 in the anti-rotation device 5, and the rotating plate 55 drives the second screw 54 to rotate. The second screw 54 is threadedly connected to the connecting shell 51, and the second screw 54 is bearing-connected to the connecting plate 53, and the outer side of the connecting plate 53 is close to the inner side of the connecting shell 51, so the second screw 54 drives the connecting plate 53 to descend, and then drives the rubber block 52 to press and fix the circular arrow assembly 2, thereby preventing it from rotating and preventing the scale it points to from changing, which better meets the work needs in different situations.
