Description

Technical Field

[0001] The invention relates to the technical field of road surface leveling, and in particular to a leveling device for a continuously reinforced concrete road surface in a highway engineering. Background Art

[0002] Longitudinal continuous steel bars and transverse steel bars are arranged in the surface layer of continuously reinforced concrete pavement. After reinforcement, scattered cracks with very small gaps are allowed to appear in the road slab. Except for construction joints, transverse joints can be eliminated, and end joints are only set at the ends of the slabs or at the connection with the structure with a few expansion joints or anchoring structures. This improves the driving quality of the road surface and reduces maintenance work. After the transverse and longitudinal steel bars are arranged, they need to be covered with cement. When the cement is laid, in order to ensure the flatness of the concrete pavement after solidification, a leveling device will be used to level the laid concrete.

[0003] However, there are some shortcomings in the current concrete pavement leveling device. When the existing leveling roller is leveling concrete, a certain amount of concrete will stick to its surface, which will cause potholes in the leveled road surface during the subsequent leveling operation. In addition, the guide roller of the existing leveling device directly guides the excess concrete on both sides to the middle, which causes a large amount of concrete to accumulate in front of the guide roller, seriously affecting the efficiency of the concrete pavement leveling work.

[0015] The working principle and beneficial effects of the present invention are: 1. The present invention scrapes off the concrete adhered to the curved surface of the leveling roller through the contact between the guide plate and the leveling roller, and enters the upper surface of the guide plate. The connecting shaft drives the cylindrical sleeve and the sliding ring to rotate, and the compression spring squeezes the sliding ring to make the outer friction plate in close contact with the inner friction plate. When the rotating inner friction plate is completely in contact with the rotating outer friction plate, the rotating outer friction plate drives the inner friction plate and the rotating sleeve to rotate a certain angle. During the process, the sliding block slides along the arc rod at a certain angle. When the thrust of the curved spring on the guide plate is greater than the friction between the outer friction plate and the inner friction plate, the curved spring pushes the sliding block to quickly reset, thereby causing the guide plate to vibrate, and then causing the concrete on the upper surface of the guide plate to slide down, thereby solving the problem that a certain amount of concrete will stick to the surface of the existing leveling roller when leveling concrete, which will cause potholes in the leveled road surface during subsequent leveling operations, and at the same time, concrete accumulation on the upper surface of the guide plate is avoided, further ensuring the cleaning effect of the leveling roller.

[0016] 2. The present invention drives the second pulley to rotate through the second transmission belt. The rotation of the second pulley will drive the rear rotating roller and the transmission wheel to rotate. The rear transmission wheel drives the front transmission wheel and the rotating roller to rotate through the belt. At this time, the front spiral piece and the rear spiral piece are both in a rotating state. The rotating front spiral piece will guide the excess concrete above the upper surface of the steel plate to both sides, and the existing potholes will be filled in the process. Excessive concrete will be guided to the middle part by the rotating rear spiral piece, so as to fill the unfilled potholes, thereby solving the problem that the existing guide rollers directly guide the excess concrete on both sides to the middle part, causing a large amount of concrete to accumulate in front of it, which seriously affects the concrete pavement leveling work.

[0017] 3. The present invention changes the relative distance between the counterweight and the central axis of the tamping roller by extending or shortening the telescopic rod. After the position of the counterweight is adjusted, the driving wheel three rotates, which drives the pulley three to rotate through the transmission belt three, and the pulley three drives the tamping roller to rotate. Since the counterweight is biased toward one side of the tamping roller, the tamping roller vibrates, and the tamping roller vibrates the concrete below. According to different concrete compositions, the vibration amplitude of the tamping roller is changed until it is a suitable amplitude, thereby ensuring good density and flatness of the concrete and further improving the ultimate strength and durability of the concrete.

The driving wheel 13 is connected to the driving belt 188, the middle of the two connecting frames 181 are fixedly installed with wheels 189, the connecting frames 181 are fixedly connected to the rectangular plate 8, the front spiral piece 185 is shorter than the middle of the rotating roller 182, the diameter of the tamping roller 31 is equal to the diameter of the leveling roller 5, the diameter of the front spiral piece 185 and the rear spiral piece 186 are equal to the diameter of the leveling roller 5, the spiral directions of the front spiral piece 185 and the rear spiral piece 186 are opposite, and the front spiral piece 185 and the rear spiral piece 186 are geometrically aligned with the two sets of rotating rollers 182. The plurality of inner friction plates 76 and the plurality of outer friction plates 710 are arranged equidistantly around the center, and the gap between the individual outer friction plates 710 is larger than that between the two adjacent inner friction plates 76, so as to prevent the individual outer friction plates 710 from entering the gap between the inner friction plates 76 due to the thrust of the compression spring 78. The function of the plurality of inner friction plates 76 is to drive the second pulley 187 to rotate through the second transmission belt 188, and the rotation of the second pulley 187 will drive the rear rotating roller 182 and the transmission wheel 183 to rotate, and the rear transmission wheel 183 will drive the front transmission wheel 184 through the belt 184.

Excess concrete will be guided to the middle by the rotating rear spiral piece 186, so as to fill the unfilled potholes, thereby solving the problem that the existing guide rollers directly guide the excess concrete on both sides to the middle, causing a large amount of concrete to accumulate in front of it, which seriously affects the leveling work of the concrete pavement.

[0025] Working principle: When the present invention is used, the device is placed on a concrete road surface that needs to be leveled. At this time, the leveling roller 5 and the wheel 189 are in contact with the upper surfaces of the steel plates on both sides of the road surface. The controller 17 is controlled to make the motor 1 9 and the motor 2 12 work. When the motor 2 12 works, it will drive the driving wheel 2 13 and the driving wheel 3 14 to rotate. The driving wheel 2 13 drives the pulley 2 187 to rotate through the transmission belt 2 188. The rotation of the pulley 2 187 will drive the rear rotating roller 182 and the transmission wheel 183 to rotate. The rear transmission wheel 183 drives the front transmission wheel 183 and the rotating roller 182 to rotate through the belt 184. At this time, the front spiral piece 185 and the rear spiral piece 186 are both in a rotating state. The rotating front spiral piece 185 will guide the excess concrete higher than the upper surface of the steel plate to both sides. In the process, the existing potholes will be filled. Excessive concrete will be guided to the middle by the rotating rear spiral piece 186, thereby filling the unfilled potholes. The driving wheel 314 rotates, and the transmission belt 37 drives the pulley 36 to rotate, and the pulley 36 drives the tamping roller 31 to rotate. Since the counterweight block 33 is biased toward one side of the tamping roller 31, the tamping roller 31 vibrates, and the tamping roller 31 vibrates the concrete below. Before use, the telescopic rod 34 is extended or shortened to change the relative distance between the counterweight block 33 and the central axis of the tamping roller 31, thereby changing the vibration amplitude of the tamping roller 31; The operation of the motor 9 drives the driving wheel 10 to rotate, and the driving wheel 10 drives the pulley 6 to rotate through the transmission belt 11. The rotation of the pulley 6 drives the leveling roller 5 to rotate. The rotation of the leveling roller 5 will level the middle concrete pavement after the tamping roller 31 is vibrated, and at the same time push the device forward; the guide plate 71 contacts the leveling roller 5, and the concrete adhered to the curved surface of the leveling roller 5 will be scraped off and enter the upper surface of the guide plate 71. The rotation of the connecting shaft 4 drives the cylindrical sleeve 77 and the sliding ring 79 to rotate, and the compression spring 78 squeezes the sliding ring 79, so that the outer friction plate 710 is in close contact with the inner friction plate 76. Since there is friction between the outer friction plate 710 and the inner friction plate 76, when the rotating inner friction plate 76 and the rotating outer friction plate 7 10 When the contact is complete, the rotating outer friction plate 710 will drive the inner friction plate 76 and the rotating sleeve 75 to rotate a certain angle. During the process, the sliding block 72 will slide a certain angle along the arc rod 73 and squeeze the curved spring 74. With the squeezing, the thrust of the curved spring 74 on the sliding block 72 will gradually increase. When the thrust of the curved spring 74 on the guide plate 71 is greater than the friction between the outer friction plate 710 and the inner friction plate 76, the curved spring 74 will push the sliding block 72 to quickly reset, thereby causing the guide plate 71 to vibrate, and then causing the concrete on the upper surface of the guide plate 71 to slide down. During the reset of the sliding block 72, the contact area between the inner friction plate 76 and the outer friction plate 710 will become smaller, that is, the friction between the outer friction plate 710 and the inner friction plate 76 will decrease.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
