DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-4 The device for detecting the thickness of loose paving during road construction shown in the figure comprises a chassis 1 and a universal level 2. The universal level 2 is arranged on the top of the chassis 1. The chassis 1 is provided with multiple level adjustment mechanisms. The level adjustment mechanism comprises a threaded sleeve 4. An annular cavity is provided in the chassis 1. Rotary holes are provided on the opposite inner walls of the annular cavity. Threaded sleeves 4 are installed in two rotating holes for common rotation. A screw 5 is installed on the inner thread of the threaded sleeve 4. A supporting foot 6 is provided at the bottom end of the screw 5 through a movable component. A rotating component is provided on the threaded sleeve 4. A limiting component is provided at the top of the screw 5. A fixed cylinder 3 is fixed on the top of the chassis 1. The relative inner walls of the fixed cylinder 3 are commonly fixedly installed with a fixing rod 14, and a sliding sleeve 15 is slidably installed on the fixing rod 14. A sliding hole is opened on the circumferential inner wall of the fixed cylinder 3, and an upper circular plate 16 is fixedly sleeved on the sliding sleeve 15. A pressing mechanism is provided on the top of the upper circular plate 16. A rectangular plate 19 is fixedly installed on the circumferential outer wall of the upper circular plate 16, and a scale steel bar 20 is fixedly installed on the bottom of the rectangular plate 19. A lower circular plate 21 is slidably installed on the sliding sleeve 15, and a reset mechanism is provided on the top of the lower circular plate 21. An observation plate 23 is fixedly installed on the circumferential outer wall of the lower circular plate 21, and the observation plate 23 is slidably installed on the scale steel bar 20.

[0024] With the above structure, when in use, the chassis 1 is first placed on an unpaved road surface, with the scale steel bar 20 positioned above the loose road surface. Due to the arrangement of the movable assembly, each support foot 6 can be aligned with the ground, preventing the chassis 1 from tilting due to uneven ground. The levelness is then observed using the universal level 2. When adjustment is required, the threaded sleeve 4 is rotated by the rotating assembly, and the screw 5 is then driven upward or downward by the combined action of the thread and the limit assembly, thereby adjusting the levelness of the chassis 1. After the level is adjusted, the upper circular plate 16 is moved downward by the pressing mechanism, thereby driving the sliding sleeve 15 and the lower circular plate 21 to move downward synchronously. When the observation plate 23 contacts the surface of the loose road surface, it stops under the action of the loose road surface. At this time, the upper circular plate 16 continues to move downward, thereby driving the rectangular plate 19 and the scale steel bar 20 to move downward and insert into the loose road surface. The scale on the scale steel bar 20 is observed through the observation plate 23, thereby achieving the thickness measurement function.

[0025] like Figure 3 As shown, the movable component includes a movable ball 7, which is fixedly installed at the bottom end of the screw 5. A ball groove is provided at the top of the supporting foot 6, and the movable ball 7 is movably installed in the ball groove. The advantage of this arrangement is that through the arrangement of the movable ball 7, the movable function of the supporting foot 6 can be realized, thereby better fitting the road surface.

[0026] Specifically, when the chassis 1 is placed on the ground, multiple supporting feet 6 are in contact with the ground. Due to the setting of the movable balls 7, the supporting feet 6 can be freely adjusted to fit the ground, avoiding the chassis 1 from tilting due to the tilt of the ground.

[0027] like Figure 3 As shown, the rotating assembly includes a rotating shaft 8, the bottom end of the rotating shaft 8 is rotatably mounted on the bottom inner wall of the annular cavity, the top end of the rotating shaft 8 extends to the outside of the chassis 1 and is fixedly mounted with a knob 11, a driving gear 9 is fixedly sleeved on the rotating shaft 8, and a driven gear 10 is fixedly sleeved on the threaded sleeve 4, and the driving gear 9 is meshed with the driven gear 10. The advantage of this arrangement is that, through the arrangement of the driving gear 9 and the driven gear 10, the threaded sleeve 4 can be driven to rotate synchronously by the rotating shaft 8.

[0028] Specifically, when the screw 5 needs to be adjusted to rise or fall, the rotating shaft 8 is driven to rotate by turning the knob 11, thereby driving the driving gear 9 to engage with the driven gear 10, thereby driving the threaded sleeve 4 to rotate, and driving the screw 5 to achieve the lifting function through the action of the thread.

[0029] like Figure 3As shown, the limiting assembly includes a limiting rod 13, a limiting hole is opened on the top of the chassis 1, the limiting rod 13 is slidably installed in the limiting hole, the top of the screw 5 is fixedly installed with a fixing plate 12, and the top of the limiting rod 13 is fixedly connected to the bottom of the fixing plate 12. The advantage of this arrangement is that through the setting of the limiting rod 13, the screw 5 can be limited by the fixing plate 12 to prevent the screw 5 from rotating synchronously with the rotation of the threaded sleeve 4.

[0030] Specifically, when the threaded sleeve 4 rotates, the screw rod 5 is driven by the action of the thread to realize the lifting function. The setting of the fixing plate 12 and the limiting rod 13 can prevent the screw rod 5 from rotating synchronously with the threaded sleeve 4.

[0031] like Figure 5 As shown, the pressing mechanism includes multiple pressing shafts 17, and multiple circular holes are opened on the inner wall of the top of the fixed cylinder 3. The multiple pressing shafts 17 are slidably installed in the multiple circular holes. The bottom ends of the multiple pressing shafts 17 are fixedly installed on the top of the upper circular plate 16, and the top ends of the multiple pressing shafts 17 are jointly fixedly installed with a pressing plate 18. The advantage of this arrangement is that by setting multiple pressing shafts 7 and pressing plates 18, the upper circular plate 16 can be driven to move downward.

[0032] Specifically, when the pressing plate 18 is pressed, it drives the multiple pressing shafts 17 to move downward synchronously, thereby driving the multiple upper circular plates 16 to move downward synchronously, so as to facilitate the rectangular plate 19 and the scale steel bars to move downward synchronously for measurement.

[0033] like Figure 5 As shown, the reset mechanism includes a reset spring 22, which is sleeved on the sliding sleeve 15. The top end of the reset spring 22 is fixedly mounted on the bottom of the upper circular plate 16, and the bottom end of the reset spring 22 is fixedly mounted on the top of the lower circular plate 21. The advantage of this arrangement is that, through the arrangement of the reset spring 22, when the squeeze on the lower circular plate 21 is released, the lower circular plate 21 can be driven by its elastic action to achieve the reset function.

[0034] Specifically, when the upper circular plate 21 moves downward, it drives the sliding sleeve 15 to move synchronously, and under the connecting action of the return spring 22, it drives the lower circular plate 21 to move downward synchronously, so as to drive them to move synchronously. When the lower circular plate 21 contacts the loose road surface, the lower circular plate 21 stops moving. At this time, the upper circular plate 16 continues to move, squeezing the return spring 22. When the squeezing of the lower circular plate 21 is released, it is reset by the elastic action of the return spring 22.

[0035] like Figure 3 As shown, the bottom end of the supporting foot 6 is fixedly provided with an anti-skid pad. The advantage of such a setting is that the anti-skid pad can achieve the fixing function of the supporting foot 6, thereby preventing it from sliding.

[0036] Specifically, when the support legs 6 are in contact with the ground, the provision of the anti-skid pads can prevent them from sliding, thereby improving stability.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
