DETAILED DESCRIPTION
[0018] The embodiments of the present application are presented by way of example and description, and are not exhaustive or limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application in order to design various embodiments with various modifications for particular uses according to the principles of the present application.
[0019] Please refer to Figures 1-5 In the embodiment, a highway construction flatness detection device is provided, which comprises a cart 1 and a top rod 2. The front side end face of the cart 1 is provided with a front cavity 16. The left side end face of the front cavity 16 is rotatably provided with an adjusting lead screw 17 through a bearing. The right side end face of the adjusting lead screw 17 is provided with a first motor. The outer side wall of the adjusting lead screw 17 is provided with a first sliding block. The upper end face of the first sliding block is provided with an adjusting frame 11. One end of the adjusting frame 11 is provided with a base. The top of the base is provided with a spring rod 12. The bottom of the spring rod 12 is provided with the top rod 2. The inner side wall of the base is symmetrically provided with a fixed groove. The top of the fixed groove is provided with an upper pressure sensor 13. The bottom of the fixed groove is provided with a lower pressure sensor 14. The outer side wall of the top rod 2 is symmetrically provided with a plug. The other end of the adjusting frame 11 is provided with a dust collector 15. The dust collector 15 is arranged in front of the base. During operation, the dust collector 15 cleans the dust on the road surface, so as to avoid affecting the test accuracy of the road surface. When the road surface is concave, the spring rod 12 drives the top rod 2 to move downward, so that the plug presses on the lower pressure sensor 14 for warning treatment. When the road surface is convex, the spring rod 12 contracts, so that the top rod 2 moves upward, and the plug presses on the upper sensor for warning treatment. The first motor is started to drive the adjusting lead screw 17 to rotate, so that the adjusting frame 11 moves left and right, thereby facilitating the detection of the entire road surface. The cart 1 does not need to be pushed to move, thereby reducing the labor intensity. The present application has simple structure, low manufacturing cost, and is convenient to operate.
[0020] The upper end surface of the trolley 1 is provided with an upper seat 18, and the inner bottom of the upper seat 18 is provided with a control panel 19. The control panel 19 is electrically connected with the lower pressure sensor 14 and the upper pressure sensor 13. The rear of the upper seat 18 is provided with a first warning light 21, which is electrically connected with the upper pressure sensor 13. The right of the first warning light 21 is provided with a second warning light 22, which is electrically connected with the lower pressure sensor 14. The first warning light 21 and the second warning light 22 are controlled by the control panel 19. When the PLC program is written in the control panel 19, the operation of each device is controlled. When the upper pressure sensor 13 senses the pressure, the first warning light 21 is turned on through the control panel 19. When the lower pressure sensor 14 senses the pressure, the second warning light 22 is turned on through the control panel 19. It is convenient to intuitively understand the concave-convex flatness of the road surface, so that the road surface can be repaired in time.
[0021] The upper end surface of the adjusting frame 11 is provided with an upper frame 23, which is connected with the upper end surface of the upper seat 18 in a sliding fit manner. When working, the upper frame 23 supports the adjusting frame 11, and ensures the stability of the left and right movement of the adjusting frame 11.
[0022] The bottom of the dust collector 15 is provided with a dust suction port, and the outer side wall of the dust suction port is provided with a side cavity 24. A plurality of first springs 25 are arranged on the inner top of the side cavity 24 along the circumferential direction. The bottom of the first spring 25 is provided with an outer shell 26, and the bottom of the outer shell 26 is provided with a soft pad 27. When working, the first spring 25 drives the outer shell 26 to move downward and press on the road surface, thereby improving the dust collection effect of the dust collector 15. The soft pad 27 protects the outer shell 26 from being damaged by friction with the road surface, and also plays a certain damping effect on the dust collector 15.
[0023] When working, the dust collector 15 cleans the dust on the road surface to avoid affecting the test accuracy of the road surface. When the road surface is concave, the spring rod 12 drives the top rod 2 to move downward, so that the plugboard presses on the lower pressure sensor 14 for warning treatment. When the road surface is convex, the spring rod 12 contracts, so that the top rod 2 moves upward, and the plugboard presses on the upper sensor for warning treatment. The first motor is started to drive the adjusting screw 17 to rotate, so that the adjusting frame 11 moves left and right, thereby facilitating the detection of the entire road surface. The labor intensity is reduced, the structure of the utility model is simple, the manufacturing cost is low, and the operation is convenient.
[0024] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor shall belong to the protection scope of the present application.
