[0020] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:
[0022] like Figure 1 to Figure 4 As shown, a road structure layer paving thickness control device includes: a base fixing mechanism 1, a thickness control mechanism 2 and a wire rope winch 3, the base fixing mechanism 1 includes: a steel chassis 10, four fixing nails 11, the steel chassis 10 is drilled with four through holes at four corners, and the four fixing nails 11 are respectively penetrated in the through holes, the thickness control mechanism 2 includes a scale rod 20 and a steel tray 21, the scale rod 20 is fixedly welded at the center position of the steel chassis 10, the steel tray 21 is sleeved on the scale rod 20, and a circular hole 210 and a rectangular hole 211 are respectively opened on both sides of the steel tray 21; the wire rope winch 3 includes: an automatic retractor 30, a wire rope 31, and a hook 32, the automatic retractor 30 is installed on the steel chassis 10, the wire rope 31 is coiled on the drum of the automatic retractor 30, and the hook 32 is installed on the free end of the wire rope 31.
[0023] Specifically, when in use, at least two devices need to be used at the same time. The steel chassis 10 is fixed to the ground by the fixing nails 11, and the height of the steel pallet 21 is adjusted according to the paving thickness. The free end of the steel wire rope 31 passes through the circular hole 210 of the steel pallet 21 of the same device, and the hook 32 is hung on the rectangular hole 211 of another device.
[0024] The thickness control mechanism 2 also includes: an active buckle 22 and a tension adjustment screw 23. The active buckle 22 is sleeved on the scale rod 20. The top of the active buckle 22 is fixedly connected to the bottom of the steel tray 21. A threaded through hole is opened on one side of the active buckle 22. The tension adjustment screw 23 passes through the threaded through hole and is threadedly connected to the active buckle 22.
[0025] Specifically, the movable buckle 22 is welded and fixed to the steel pallet 21 to form a whole, which is put on the scale rod 20 as a whole. Tightening the tension adjustment screw 23 to press it against the scale rod 20 can fix the movable buckle 22 on the scale rod 20. Loosening the tension adjustment screw 23 can make the movable buckle 22 and the steel pallet 21 slide up and down on the scale rod 20, which is used to quickly adjust the paving thickness during construction.
[0026] The wire rope winch 3 also includes: a fixed chuck 33 and a rotating buckle 34. The fixed chuck 33 is fixedly mounted on the outer surface of the automatic recoverer 30. A circle of limiting holes is evenly arranged on the fixed chuck 33. One end of the rotating buckle 34 is fixedly connected to the drum shaft of the automatic recoverer 30, and the other end is equipped with a limiting column 35 adapted to the shape of the limiting hole.
[0027] Specifically, when the limiting column 35 is clamped in the limiting hole, the drum shaft of the automatic reclaimer 30 can be fixed; when the wire rope 31 needs to be pulled out or recovered, the limiting column 35 is pulled out from the limiting hole of the fixed chuck 33 and the rotating buckle 34 is rotated.
[0028] A mounting plate 12 is fixedly mounted on the steel chassis 10, and protrusions are fixedly connected on both sides of the mounting plate 12. A mounting sleeve 36 is mounted on the back of the automatic recycler 30, and a slide groove adapted to the shape of the protrusion is provided on the inner side of the mounting sleeve 36, and the mounting plate 12 is clamped on the inner side of the mounting sleeve 36.
[0029] Specifically, the mounting sleeve 36 is inserted from above onto the mounting clamp plate 12 to fix the wire rope winch onto the base fixing mechanism 1 .
[0030] The circular hole 210 and the rectangular hole 211 reserve grooves having the same diameter as the steel wire rope 31 at the position where the steel wire rope 31 is extended and hung.
[0031] Specifically, the steel wire rope 31 passes through the groove, so that the upper surface height of the steel tray 21 and the steel wire rope 31 are consistent.
[0032] One end of the tension adjustment screw rod 23 in contact with the scale rod 20 is provided with a rubber sleeve.
[0033] Specifically, the tension adjustment screw 23 is prevented from wearing the scale of the scale rod 20 .
[0034] The steel chassis 10 is a steel plate of 250mm×250mm×10mm, the diameter of the through hole is 6mm, the center of the through hole is set at a position 20mm away from the two adjacent sides of the steel chassis 10, the length of the fixing nail 11 is 8mm, and the mounting card 12 is installed at a position 50mm away from the side of the steel chassis 10.
[0035] Specifically, the base fixing mechanism 1 has good stability and load-bearing capacity to adapt to different road surfaces and construction requirements.
[0036] The scale rod 20 is a solid round steel with a diameter of 14 mm, and the side marked with scale is flat. The steel tray 21 is a steel plate of 150 mm×150 mm×5 mm. The diameter of the circular hole 210 is 20 mm, and the size of the rectangular hole 211 is 20 mm×15 mm.
[0037] Specifically, the solid round steel ensures the strength of the scale rod 20 .
[0038] The length of the steel wire rope 31 is 25 m and the diameter is 8.3 mm.
[0039] Specifically, it is convenient for the automatic retractor 30 to retract the wire rope 31 .
[0040] The method of using the present invention is as follows: before the paving operation, a row of road structure layer paving thickness control devices are placed on the left and right sides of the paver, with an interval of 20m between two adjacent road structure layer paving thickness control devices, and the height of the steel pallet 21 is adjusted according to the paving thickness.
[0041] When in use, the limit column 35 is pulled out from the limit hole of the fixed chuck 33, the free end of the steel wire rope 31 is passed through the circular hole 210 of the steel tray 21 of the same device, the hook 32 is hung on the rectangular hole 211 of the adjacent device, the rotating buckle 34 is manually rotated to tighten the steel wire rope 31 and insert the limit column 35 into the fixed chuck 33. The steel wire rope 31 is parallel to the paving surface of the paver and is in a suitable working position. The paver sensor is placed on the steel wire rope 31 and moves through the device to adjust the required paving thickness. As the paver moves forward, the material is spread on the road surface, thereby realizing the control of the road paving thickness. During the construction process, the construction personnel should always observe the scale markings of the steel tray 21 and whether the steel wire rope 31 is tied tightly, and make adjustments in time if there is any abnormality.
[0042] The device can be recycled. After completing a stage of paving tasks, it can be easily disassembled from the current paving thickness control point and flexibly transferred to the next paving area for reinstallation. After the construction is completed, the residual materials on the device should be cleaned in time, and the device should be inspected and maintained in preparation for the next use.
[0043] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
