Description

Technical Field

[0001] The invention relates to the technical field of motor cooling towers, in particular to a leveling device for asphalt pavement construction. Background Art

[0002] The flatness of asphalt pavement is an important indicator to measure the quality of the pavement. If it is not leveled, the road surface will appear uneven, and vehicles driving on uneven roads will experience bumps, affecting driving comfort. At the same time, asphalt pavement has a design thickness requirement. During the construction process, if it is not leveled, the laying thickness of the asphalt material will be uneven.

[0003] After searching, the patent document with the announcement number CN219951623U discloses a leveling device for asphalt pavement construction. The device is provided with a centrifugal suction pump. When the leveling plate is horizontally moved left and right for leveling operation, the excess asphalt is sucked by the centrifugal suction pump, cut into small pieces by the dividing blade, and finally sucked into the storage box for storage. In this way, during use, it is avoided that the asphalt raised on the road can only be shoveled to one side, resulting in the need for manual collection, which is time-consuming and labor-intensive during operation. At the same time, the device can be used according to the width of the road through the movement of the screw rod during use, so that the device has no limitations during use.

[0004] However, the above-mentioned leveling device has the following defects when used: First, when using a pump body to suck material, the suction intensity cannot be accurately controlled according to the amount of asphalt shoveled out during the leveling process, which makes it easy for asphalt to accumulate during the leveling process, affecting the leveling effect; At the same time, the leveling effect of rollers is mixed, and the leveling range is small.

[0022] In order to be able to quickly push the asphalt aggregate during the leveling process and transport it through the conveying blade 8, as shown in the figure Figure 2-3 As shown, a quick pushing mechanism for pushing materials is provided inside the screed plate 3, and the quick pushing mechanism includes a telescopic tube 12, a controller 18 is fixedly provided on the outer wall of the support block 1, a density sensor 19 is fixedly provided on the end of the telescopic tube 12, and the controller 18, the density sensor 19, the dual-axis motor 28 and the control motor 9 are connected and arranged through a wireless sensor module, one end of the telescopic tube 12 is fixedly provided inside the screed plate 3, a mounting plate 13 is fixedly provided on the top of the screed plate 3, and a reciprocating screw rod 14 is rotatably penetrated inside the mounting plate 13, and the reciprocating screw rod The rod wall sliding sleeve of 14 is provided with a movable plate 15, the lower end of the movable plate 15 passes through the screed plate 3 and is fixedly connected to the telescopic tube 12, the end of the reciprocating screw rod 14 is provided with a self-driving mechanism for driving the reciprocating screw rod 14 to rotate, and the top of the screed plate 3 is provided with a strip hole for cooperating with the sliding of the movable plate 15, the self-driving mechanism includes a bevel gear ring 16 and a bevel gear 17, the bevel gear ring 16 is fixedly sleeved on the lower end of the outer wall of the feed barrel 2, the bevel gear 17 is fixedly connected to one end of the reciprocating screw rod 14 away from the mounting plate 13, and the bevel gear 17 is matched with the bevel gear ring 16.

[0023] In order to facilitate the pushing of the device so that it can perform stable asphalt leveling and collection work on the asphalt pavement surface, such as Figure 1 As shown, the driving assembly includes a support frame 20, which is fixedly connected to the support block 1. A transmission shaft 21 is passed through the lower ends of both sides of the support frame 20 and rotates together. Both ends of the transmission shaft 21 are fixedly sleeved with walking wheels 22. A pushing handle 23 is fixedly provided at the top of the support frame 20 and at the end away from the support block 1.

[0024] In summary, when the leveling device for asphalt pavement construction is used, before leveling the asphalt surface, the operator holds the pushing handle 23 and pushes the support frame 20. At this time, the support frame 20 drives the device to move on the asphalt pavement under the walking support of multiple walking wheels 22. At this time, the bottom of the leveling plate 3 also contacts the inner surface of the asphalt, and then the double-axis motor 28 is started to make the two worms 29 rotate at the same time. Under the self-locking engagement of the worm 29 and the worm wheel 30, the worm wheel 30 rotates stably on the outside of the feed barrel 4, and through the cooperation of the connecting plate 11, the leveling plate 3 follows the rotation of the worm wheel 30. At this time, the leveling plate 3 can quickly rotate and level the surface of the asphalt pavement. Since the leveling plate 3 is symmetrically arranged on both sides, the leveling range can be increased and the leveling efficiency can be improved. During the rotation of the screed plate 3, the asphalt aggregate on the surface of the asphalt pavement can be scraped and collected and enter the screed plate 3 through the collecting groove 4. As the screed plate 3 rotates continuously, the bevel gear 17 follows the screed plate 3 to perform a stable revolution, and the bevel gear ring 16 is fixed in position. Therefore, while the bevel gear 17 revolves around the bevel gear 16, the bevel gear 17 itself rotates and drives the reciprocating screw 14 to rotate, so that the moving plate 15 drives the front end of the telescopic tube 12 to cooperate stably under the sliding cooperation inside the strip hole. At this time, the end of the telescopic tube 12 can The aggregate entering the screed plate 3 is pushed stably and moved to the bottom of the feed barrel 4. Before the screeding work is carried out, the control motor 9 can be turned on, so that the two rotating rods 7 rotate synchronously under the drive of the synchronous wheel 24 and the synchronous belt 25, so that the conveying blade 8 can rotate stably in the feed barrel 4. When the telescopic tube 12 pushes the asphalt aggregate to the lower end of the conveying blade 8, the asphalt aggregate can be stably moved upward by the drive of the conveying blade 8, and finally enters the storage tank 26 on the top of the support block 1 through the guide pipe 27, so that the excess asphalt is effectively collected; During the pushing process of the telescopic tube 12, the sealing sensor 19 at the end of the telescopic tube 12 can be inserted into the asphalt aggregate. When the asphalt aggregate accumulates inside the screed plate 3, the sealing sensor 19 detects a larger density and transmits a signal to the controller 18. At this time, the controller 18 controls the speed of the control motor 9 to increase, while the speed of the dual-axis motor 28 decreases. While reducing the speed of the screed plate 3, the conveying blade 8 rotates rapidly, and the asphalt accumulated in the screed plate 3 is quickly transported outward, ensuring that there is enough space on the screed plate 3 to collect the asphalt aggregate, thereby improving the leveling effect.
