DETAILED DESCRIPTION

[0028] The embodiment of the present invention provides a device for detecting leveling of assembled road plates. Figure 1-2As shown, the vehicle body 11 includes a vehicle body 11, a flap 13, a first swing arm 15, a second swing arm 18, a detection mechanism and a driving mechanism. The vehicle body 11 is composed of a horizontal portion located at the upper side and a vertical portion located at the lower side. A turnover groove 14 is provided in the horizontal portion of the vehicle body 11. The first swing arm 15 is provided in the turnover groove 14. The first swing arm 15 is hinged to the inner wall of the turnover groove 14. A rotation cavity 17 is provided in the first swing arm 15. The second swing arm 18 is provided in the rotation cavity 17. The other end of the second swing arm 18 extends to the outside of the rotation cavity 17. The fixing head 12 is fixedly provided on the vehicle body 11. On the vertical part of the body 11, the fixed head 12 is located on the lower side of the body 11, the flap 13 is hinged to the inner side of the fixed head 12, a hinge head 19 is fixedly provided on the upper end surface of the flap 13, one end of the second swing arm 18 is hinged to the inner wall of the rotating cavity 17, the other end of the second swing arm 18 is hinged to the hinge head 19, a sliding cavity 22 is opened in the flap 13, a detection mechanism is arranged in the sliding cavity 22, the detection mechanism is used to detect the surface angle of the road plate, the driving components are arranged on both sides of the vertical part of the body 11, and the driving components are used to reduce the friction during the movement of the body 11.

[0029] A handle 16 is fixed to the upper end of the first swing arm 15, and the handle 16 can swing toward the side close to the vehicle body 11 or away from the vehicle body 11. Furthermore, since some assembled road panels are very heavy, even up to two tons, a transverse hydraulic structure is installed at the handle 16, so that it can push the second swing arm 18 to complete the detection.

[0030] like Figure 2-4 As shown, the detection mechanism includes a detection column 23, a detection slide 24, an adjustment plate 25 and a varistor 26. The detection column 23 is fixed on the upper wall of the sliding cavity 22, the detection slide 24 is slidably arranged in the detection column 23, the lower end of the detection slide 24 extends to the outside of the detection column 23, the adjustment plate 25 is fixed at the lower end of the detection slide 24, the varistor 26 is fixed on the upper wall of the sliding cavity 22 and is located in the detection column 23, and an elastic member is provided between the detection slide 24 and the varistor 26, and the elastic member is used to ensure that the adjustment plate 25 is level.

[0031] The elastic member is a telescopic spring 27, one end of which is connected to the varistor 26, and the other end of which is connected to the upper surface of the detection slide column 24. A detection terminal is provided in the flap 13, and the varistor 26 is electrically connected to the detection terminal.

[0032] The sum of the lengths of the first swing arm 15 and the second swing arm 18 matches the vertical portion of the vehicle body 11 . When the first swing arm 15 and the second swing arm 18 remain in a vertical state, the flap 13 remains in a horizontal state.

[0033] The vertical portion of the vehicle body 11 is provided with a positioning groove 30 , a first sliding groove 31 and a second sliding groove 32 in sequence from the inside to the outside. The cross-sectional area of ​​the positioning groove 30 is smaller than that of the second sliding groove 32 and smaller than that of the first sliding groove 31 .

[0034] like Figure 5 As shown, the driving mechanism includes a friction component and a rotating component. The friction component is arranged in the positioning groove 30, and the rotating component is arranged on both sides of the friction component. The friction component includes a positioning plate 33 and a pressure spring 34. The positioning plate 33 is slidably arranged in the positioning groove 30, and the pressure spring 34 is fixedly arranged between the side of the positioning plate 33 close to the vehicle body 11 and the inner wall of the positioning groove 30. The pressure spring 34 is arranged in an array along the length direction of the positioning plate 33. The rotating component includes a positioning slide 35, a roller shaft 36 and a roller 37. The positioning slide 35 is slidably arranged in the positioning groove 30, and the roller shaft 36 is fixedly arranged on the side where the two positioning slides 35 are away from each other. The roller 37 is rotatably connected to the end where the two roller shafts 36 are away from each other.

[0035] The positioning slide 35 can slide in the first slide groove 31 and be limited by the inner wall of the positioning slide 35. The pressure spring 34 pushes the positioning plate 33 to slide toward the side away from the vertical part of the vehicle body 11 through the elastic force. When the positioning plate 33 and the surface of the positioning slide 35 are against each other, the friction force between the positioning plate 33 and the positioning slide 35 fixes the position of the positioning slide 35 in the first slide groove 31. The second slide groove 32 is adapted to the cross-sectional diameter and length of the roller shaft 36.

[0036] When the staff needs to level the assembled road plate, they hold the handle 16 to drive the first swing arm 15 to swing, and the first swing arm 15 drives the second swing arm 18 to swing relatively through the hinge shaft. At this time, due to the change in the angle between the first swing arm 15 and the second swing arm 18, the projected lengths of the first swing arm 15 and the second swing arm 18 are shortened, so that the flap 13 is flipped upward relatively. When the flap 13 flips to the upper limit position, the staff swings the handle 16 back to the initial state and releases the handle 16. Due to the length limit of the first swing arm 15 and the second swing arm 18, the flap 13 is , during which the flap 13 drives the adjustment plate 25 to counteract the assembled road plate through the detection column 23 and the detection slide column 24. The assembled road plate uses the reaction force to make the adjustment plate 25 drive the detection slide column 24 to rise in the detection column 23. The detection slide column 24 compresses the telescopic spring 27, thereby changing the pressure on the surface of the varistor 26. At this time, the staff detects the pressure parameters of the varistor 26 through the detection terminal, thereby detecting the relative height of the detection slide column 24, and then obtaining the flatness feedback of the plate surface, which is convenient for the staff to level.

[0037] like Figure 6 As shown, by adjusting the relative heights of the two rollers 37, the flap 13 can be positioned on the step to level the assembled road slab close to one side of the step.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
