Description

Technical Field

[0001] The present invention belongs to the technical field of concrete panel rolling, and in particular relates to an asphalt concrete panel rolling device and method. Background Art

[0002] Asphalt concrete panel is an anti-seepage structure used on the surface of hydraulic structures, mainly composed of materials such as asphalt, mineral powder, sand and gravel. It is spread on the surface of hydraulic structures after heating and mixing, and compacted at high temperature. It has good anti-seepage, deformation adaptation, water stability and thermal stability. The components of asphalt concrete panel include panel, cushion layer, dam body and downstream drainage body. Asphalt concrete is made by heating asphalt, mineral powder, sand and gravel to 180-220 degrees, mixing and evenly spreading them on the upstream dam surface, and compacting them at 140-180 degrees. This material not only has good anti-seepage and deformation adaptation properties, but also has certain water stability and thermal stability. Therefore, it is widely used in hydraulic structures such as earth-rock dams and reservoirs.

[0003] In the prior art, since the dam body is inclined at a certain angle, when paving asphalt concrete panels on the dam body, a main winch frame and an auxiliary winch frame are required to tow construction machinery such as slope pavers, vibratory rollers, and dump trucks to ensure normal operation of the construction machinery on the slope of the dam body. During the paving process of the asphalt concrete panel for the dam body, due to the influence of the dam body working surface, labor, mechanical equipment, asphalt concrete paving quality, etc., unevenness, material shortage and other phenomena are prone to occur, resulting in insufficient compaction of the asphalt concrete panel and inability to ensure the compaction effect of the asphalt concrete panel. During the rolling process of the rolling device, the asphalt concrete is paved for the second time at any time according to the quality of the paving of the asphalt concrete panel. The dump truck needs to unload the material again under the traction of the auxiliary winch frame, which is time-consuming and labor-intensive, and seriously affects the construction progress of the project. The secondary material replenishment of the dump truck will also cause rolling damage to the asphalt concrete panel for paving of the dam body that has been completed. At the same time, when operating the asphalt concrete panel rolling device, the construction personnel need to check the rolling quality of the rolling device at any time. Due to the operation on the inclined dam body, the operating personnel’s visual field is limited, and the compaction effect of the asphalt concrete panel cannot be accurately observed, which affects the construction quality of the asphalt concrete panel.

By setting the cab 10, the viewing angle of the construction personnel is increased, which is convenient for the construction personnel to observe the compaction effect of the asphalt concrete panel. Two guide mechanisms 4 are arranged in front of the front vehicle body 1. By setting the guide mechanisms 4, the entire device is towed, so that the device can operate on a slope with a certain slope.

[0078] like Fig.11 A method for rolling an asphalt concrete panel is shown, comprising the following steps:

[0079] Step 1: Connect the asphalt concrete panel rolling device: pass the steel wire rope of the auxiliary gallows vehicle through the two wire guide mechanisms 4 on the side of the front vehicle body 1, and fix the steel wire rope to the auxiliary gallows vehicle by passing it around the wire wheel 402, and connect and pull the asphalt concrete panel rolling device, and move the asphalt concrete panel rolling device to a slope with a certain slope for operation;

[0080] Step 2: Vibration compaction of the asphalt concrete panel: first start the driving mechanism 8 to push the asphalt concrete panel rolling device to move, the driving motor 806 drives the rolling roller 708 to rotate, the rolling roller 708 rotates to drive the asphalt concrete panel rolling device to move back and forth, and then compacts the asphalt concrete panel, and then start the vibration mechanism 7 to vibrate and compact the asphalt concrete panel, the vibration motor 701 drives the cam 707 to rotate, under the action of the center of gravity of the cam 707, the rotation of the cam 707 generates vibration and synchronously drives the rolling roller 708 to vibrate, and the rolling roller 708 vibrates to vibrate and compact the asphalt concrete panel;

[0081] Step 3, take care of the rolling roller: During the rolling process, the scraping mechanism 6 scrapes off the stones adhering to the outside of the rolling roller 708, and the compression spring 602 pushes the scraper 601 to contact the rolling roller 708 to prevent the stones from adhering to the outside of the rolling roller 708, which causes the surface of the concrete panel to be uneven. The watering mechanism 11 sprays water on the rolling roller 708 to prevent the outer side of the rolling roller 708 from adhering to the asphalt concrete mixture, and takes care of the rolling roller 708 to ensure the compaction effect of the asphalt concrete panel.

[0082] Step 4: Omnidirectional vibration compaction of the asphalt concrete panel: When the asphalt concrete panel rolling device needs to turn, by starting the first telescopic rod 301 to extend and retract, the two first telescopic rods 301 move in opposite directions, thereby controlling the movement direction of the asphalt concrete panel rolling device, maintaining the construction process of step 2 and step 3, and realizing omnidirectional vibration compaction of the asphalt concrete panel;

[0083] Step 5, observe whether there are defects on the surface of the asphalt concrete panel: the cab 10 can rotate 180 degrees, and the rotary motor 1001 drives the cab 10 to rotate, which increases the viewing angle of the construction personnel and facilitates the construction personnel to observe the compaction effect of the asphalt concrete panel. When there are no defects on the surface of the asphalt concrete panel, perform steps 2 to 4; when it is observed that the surface of the asphalt concrete panel has unevenness and material shortage defects, perform step 6;

[0084] Step six, filling the surface of the asphalt concrete panel: start the filling mechanism 9 to fill the surface of the asphalt concrete panel, the swing wheel 902 drives the stirring wheel 908 to swing back and forth, the stirring wheel 908 swings back and forth to stir the asphalt concrete mixture in the silo 905, the silo 905 drives the limiting column 904 to slide in the arc-shaped through hole of the rotating plate 901 to prevent the asphalt concrete mixture in the silo 905 from leaking, the second telescopic rod 928 drives the left baffle plate 921 and the right baffle plate 922 to move in the opposite direction, put the asphalt concrete mixture at the specified position, and fill and compact the surface of the asphalt concrete panel.

[0085] When the present invention is used, the steel wire rope of the auxiliary gallows vehicle is passed through the two wire guide mechanisms 4 on the side of the front vehicle body 1, and the steel wire rope is passed around the wire pulley 402 and fixed to the auxiliary gallows vehicle. Since the front vehicle body 1 and the rear vehicle body 2 are both provided with a vibration mechanism 7 and a driving mechanism 8, during construction work, the driving mechanism of the front vehicle body 1 can be started according to actual needs, and the vibration mechanism 7 of the rear vehicle body 2 can be used for rolling, or the driving mechanism of the rear vehicle body 2 can be started, and the vibration mechanism 7 of the front vehicle body 1 can be used for rolling. First, start the driving mechanism 8 to push the device to move, and then start the vibration mechanism 7 to compact the asphalt concrete panel. During the compaction process, the scraping mechanism 6 scrapes off the stones adhered to the outside of the rolling roller 708, and the compression spring 602 pushes the scraper 601 to contact the rolling roller 708 to prevent the outer side of the rolling roller 708 from adhering to the stones, resulting in an uneven surface of the concrete panel. The watering mechanism 11 sprays water on the rolling roller 708 to prevent the outer side of the rolling roller 708 from adhering to the asphalt concrete mixture, thereby ensuring the compaction effect of the asphalt concrete panel. When the rolling device needs to turn, by starting the first telescopic rod 301 to extend and retract, the two first telescopic rods 301 move in opposite directions to control the movement direction of the device. When it is observed that the surface of the asphalt concrete panel is uneven or lacking in material, start the feeding mechanism 9 to feed the surface of the asphalt concrete panel to ensure that the asphalt concrete panel is compacted and smooth, thereby improving the construction quality.

[0086] When the driving mechanism 8 is started to push the device to move, the output end of the driving motor 806 drives the driving gear 802 to rotate, and the driving gear 802 is meshed with the reduction gear 803. The rotation of the driving gear 802 drives the reduction gear 803 to rotate, and the reduction gear 803 is meshed with the driven gear 804. The rotation of the reduction gear 803 drives the driven gear 804 to rotate. The rotation of the driven gear 804 drives the rolling roller 708 to rotate, and the rotation of the rolling roller 708 drives the rolling device to move.

[0087] The vibration mechanism 7 is started to compact the asphalt concrete panel. The output end of the vibration motor 701 drives the vibration shaft 702 to rotate. The rotation of the vibration shaft 702 drives the four active pulleys 703 to rotate. Under the action of the power belt 704, the rotation of the active pulley 703 drives the driven pulley 705 to rotate. The rotation of the driven pulley 705 drives the driven shaft 706 to rotate. The rotation of the driven shaft 706 drives the cam 707 to rotate. Under the action of the center of gravity of the cam 707, the rotation of the cam 707 generates vibration and synchronously drives the rolling roller 708 to vibrate. The vibration of the rolling roller 708 compacts the asphalt concrete panel.

[0088] When the angle of the cab 10 needs to be adjusted, the rotating motor 1001 is started, and the output end of the rotating motor 1001 drives the rotating gear 1002 to rotate. The rotating gear 1002 is meshed and connected with the rotating ring gear 1003. The rotation of the rotating gear 1002 drives the rotating ring gear 1003 to rotate, and the rotating ring gear 1003 drives the cab 10 to rotate. By rotating the cab 10, the viewing angle of the construction personnel is increased, which facilitates the construction personnel to observe the compaction effect of the asphalt concrete panel.

[0089] When a position where feeding is required is observed, the feeding mechanism 9 is started to feed the surface of the asphalt concrete panel, and the asphalt concrete mixture is poured into the silo 905. The reduction gear 803 rotates to drive the internal shaft to rotate, and the shaft rotation drives the synchronous wheel 805 to rotate. Under the action of the connecting rod 906, the synchronous wheel 805 rotates to drive the swing wheel 902 to swing back and forth, and the reciprocating swing of the swing wheel 902 drives the swing shaft 903 to rotate back and forth. The reciprocating rotation of the swing shaft 903 drives the stirring rod 907 to swing back and forth. The stirring wheel 908 is driven to swing back and forth, and the reciprocating swing of the stirring wheel 908 stirs the asphalt concrete mixture in the silo 905 to prevent it from hardening and becoming unusable. When the rolling device is operating on a slope with a certain slope, under the action of the center of gravity of the silo 905, the silo 905 drives the limit column 904 to slide in the arc-shaped through hole of the rotating plate 901, so that the silo 905 always maintains a state parallel to the working surface to prevent the asphalt concrete mixture in the silo 905 from leaking out and the asphalt concrete panel cannot be replenished.

[0090] When it is observed that the asphalt concrete panel is uneven or lacking in material, the travel motor 927 is started, and the output end of the travel motor 927 drives the travel gear 924 to rotate, and the travel gear 924 is meshed and connected with the travel rack 923. Under the action of the travel rack 923, the travel gear 924 drives the travel plate 929 to slide on the two sliding rods 909. When the travel sensor 926 coincides with the position of the specified opening and closing sensor 925, the second telescopic rod 928 is started, and the output end of the second telescopic rod 928 pushes the push rack 911 to move to one side, and the push rack 911 is meshed and connected with the two opening and closing gears 913. The push rack 911 moves to one side and drives the two opening and closing gears 913 to rotate in the opposite direction. The two opening and closing gears 913 rotate in the opposite direction and drive the other ends of the two push rods 914 to move to both sides. The other end of the push rod 914 moves to both sides and drives the sliding block 916 to move between the left baffle plate 921 and the right baffle plate 9 22 slides in the T-shaped slide groove on the lower surface of the two push rods 914, and the other ends of the two push rods 914 move to both sides to push the left and right baffle plates 921 and 922 to move in the opposite direction. The left and right baffle plates 921 and 922 move in the opposite direction, driving the reset blocks 919 at both ends to move in the opposite direction. The reset blocks 919 at both ends move in the opposite direction to stretch the tension spring 918. At this time, the asphalt concrete mixture is placed in the specified position through the square through holes of the hopper 905 and the opening and closing seat 917, and the asphalt concrete panel is filled. After filling, the second telescopic rod 928 is started to contract, and the tension spring 918 contracts to pull the reset blocks 919 at both ends to move towards each other. The reset blocks 919 at both ends move towards each other and drive the left and right baffle plates 921 and 922 to move towards each other. The left and right baffle plates 921 and 922 move towards each other and drive the push rack 911 to reset. At this time, the next asphalt concrete panel can be filled. After the filling is completed, the filling part is rolled by the rolling device.
