Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, in particular to an adjustable flatness tester. Background Art

[0002] An adjustable flatness tester is a precision instrument specially used to measure and evaluate the surface flatness of various materials. It has an adjustable function to adapt to objects of different sizes, shapes or measurement requirements. This tester usually uses non-contact measurement technology, such as laser, optical or mechanical probes, to obtain accurate data on the surface of the object being tested.

[0003] The prior art discloses a laser flatness tester installation device for road detection (CN212895814U). The utility model comprises a mounting plate and a detector body. First telescopic rods are connected at the four corners of the lower surface of the mounting plate. The lower ends of the two first telescopic rods on the left and the lower ends of the two first telescopic rods on the right are respectively connected with shock absorbing mechanisms. A first rectangular sleeve is connected at the middle position of the lower surface of the mounting plate. The front and rear ends of the first rectangular sleeve are respectively slidably connected with the second rectangular sleeve. The side of the connecting block away from the second rectangular sleeve is connected with the detector body. The utility model can change the distance between the two detector bodies by driving the connecting block to move left and right, thereby improving the application range of the device. By setting the shock absorbing mechanism, the mounting plate can be provided with shock absorbing protection during its movement, thereby preventing the detector body from being affected by vibration and improving the detection accuracy of the detector body.

[0004] After searching, it was found that when using the device, the connecting block needs to be adjusted left and right according to the road surface in advance to control the distance between the two detector bodies. This method requires advance operation when using and is not convenient. At the same time, there is a possibility of repeated detection between the two detector bodies, which is not conducive to the accuracy of the data; furthermore, when using the device, it is unable to smooth out stones or mud that affect the detection, so it is easy to be disturbed by stones or mud during the detection process, thereby affecting the detection effect.

[0030] The working principle is as follows: a telescopic rod, a shock absorbing mechanism and a universal wheel are fixedly arranged on the bottom surface of the mounting plate 10. The connection relationship between the mounting plate 10 and the telescopic rod, the shock absorbing mechanism and the universal wheel has been disclosed in detail in a prior art laser flatness tester installation device for road detection (CN212895814U), and will not be repeated here. The device sets a surrounding component and utilizes the rotation of the driving gear 18 to engage the transmission gear frame 15, so that the driven gear 16 is driven to realize revolution, and the driven gear 16 realizes rotation around the fixed gear 13, thereby realizing a surrounding detection, avoiding the inconvenience caused by measuring the ground width in advance, and thus ensuring the accuracy of the data; by setting a leveling structure, the surrounding component is used to cooperate with the pushing frame 19 to realize reciprocating linear pushing, and the push shovel 21 is pushed to remove the stone, and the angle of the connecting rod 23 is controlled to enable the leveling wheel 24 to contact the ground.

At this time, the driven gear 16 revolves around the fixed gear 13 and rotates at the same time.

[0033] like Figure 3 , Figure 4 and Figure 5As shown, the push frame 19 is composed of an inner annular groove and two slide posts, and the two slide posts are symmetrically arranged on both sides of the outer wall of the inner annular groove. The bottom surface of the driven gear 16 is rotatably connected with a push block 17, and the push block 17 is arranged away from the center of the driven gear 16.

[0034] The specific implementation method is as follows. When in use, the device is placed on the ground whose flatness needs to be tested, and the flatness of the ground is tested by adjusting the surrounding components and the leveling structure. Specifically, the motor 11 is started, and the driving gear 18 engages the gear ring of the gear frame 15 to rotate, and the gear frame 15 drives the driven gear 16 to revolve, and the driven gear 16 revolves around the fixed gear 13 while engaging the fixed gear 13 to rotate. At this time, the push block 17 slides in the inner annular groove of the push frame 19. In this sliding process, since the driven gear 16 rotates, the push block 17 is away from the center of the driven gear 16, so the push block 17 will push the push frame 19 to realize reciprocating motion in the two support seats 12. In this process, the tester body 27 connected to the bottom of the push block 17 will follow the movement of the push block 17 to realize surrounding detection, and the push frame 19 will push the shovel 21 to remove stones or mud, and the leveling wheel 24 uses the cleaning bristles 25 to roll and clean the ground.
