Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to drainage and noise reduction pavement paving equipment and a paving method. Background Art

[0002] There are two main methods for reducing road noise: one is to add a wear layer. That is, to lay a noise reduction functional layer on the surface, with a thickness of about 2cm, generally not more than 4cm, such as OGFC. The other is a porous noise reduction structure layer, which is the pavement structure. It has the functions of noise reduction and drainage. It is called a low-noise pavement or drainage pavement. Noise reduction pavement can reduce noise by 3~8dB. As an environmentally friendly road technology, noise reduction pavement technology has been widely used at home and abroad.

[0003] Since OGFC mixture uses more coarse aggregate and less fine aggregate, the aggregate is easy to heat up and the temperature of the aggregate is difficult to control. If the temperature of the mixture is too high, the asphalt will flow easily, and if the temperature is too low, the construction work will be difficult; improving the construction efficiency can solve the problem of insufficient temperature of the OGFC layer when rolling due to the lower temperature of the OGFC mixture to a certain extent, but the laying speed of the OGFC layer has an upper limit. Before rolling the OGFC layer, the ironing plate needs to fully iron the OGFC layer, so improving the efficiency cannot fundamentally solve the construction difficulty of the OGFC mixture due to the temperature; and because the truck cannot accurately control the falling time, speed and weight of the OGFC mixture when unloading the OGFC mixture, the auxiliary heating OGFC asphalt in the asphalt paver loading box fluctuates. In this state, relying on the traditional conveyor belt with the auger cannot meet the needs of uniform paving, and the asphalt paver driver and the truck driver need to have high professional operation experience, which greatly increases the difficulty of OGFC paving, and is accompanied by the problem of low acceptance rate of the OGFC layer.

[0004] OGFC mixture has poor temperature-maintaining ability. Failure to spread and roll it in time will cause it to solidify and stick together prematurely. Rolling will result in excessive local gaps, making it prone to collapse, potholes and other defects within the specified service life of the road. In severe cases, it can cause local waterlogging on the road, reducing or even losing the road surface's ability to drain water and reduce noise. Summary of the invention

[0035] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0037] Combine the following Figure 1-11The specific implementation mode of the present invention is described, a drainage and noise reduction pavement paving equipment and paving method, including a frame 15, a driving module 11 is fixedly provided on one side of the frame 15, and the driving module 11 is a popular concept, including the driver's driving position, the power system of the whole vehicle, the hydraulic system, etc., and the frame 15 is provided with a driving module on the primary side away from the driving module 11; the driving module includes a plurality of track wheels 27 and a track 23, the track wheels 27 are rotatably connected to the frame 15, and the track 23 is driven by the track wheels 27; the track 23 and the track wheels 27 provide power for the whole vehicle, wherein the track wheels 27 include a driving wheel, a limiting wheel, a load-bearing wheel and a track-supporting wheel etc., which can satisfy the forward and backward movement and on-the-spot steering of the present invention, wherein the driving wheel is connected to the power system of the whole vehicle and is powered by an electric motor; a paving module is provided on one side of the driving module 11, and the paving module includes an auger roller, and the auger roller includes a main auger roller 43 and an auxiliary auger roller, and a main auger blade 18 is fixedly provided on the circumference of the main auger roller 43, and an auxiliary auger blade 24 is provided on the circumference of the auxiliary auger roller, and there are two auxiliary auger blades 24, which are respectively located on both sides of the main auger blade 18; an ironing plate 13 is provided on the side of the paving module away from the driving module 11, and the ironing plate 13 is detachably mounted on one end of the frame 15. The position of the main auger roller 43 will not change, but the auxiliary auger roller can move, thereby changing the paving width. There is no need to pause the construction and debug the equipment. The adjustment can be completed during the movement of the equipment to meet the situation of sudden changes in road width. The main auger blades 18 and the auxiliary auger blades 24 always have overlapping parts, and the spirals of the main auger blades 18 and the auxiliary auger blades 24 are opposite. When the main auger roller 43 and the auxiliary auger roller turn in opposite directions, the OGFC mixture can be smoothly transported from the middle part where the main auger blades 18 and the auxiliary auger blades 24 overlap; in addition, the main auger blades 18 and the auxiliary auger blades 24 can work independently in the non-overlapping parts. When laying the OGFC layer, by changing the position of the auxiliary auger roller, it can flexibly adapt to changes in road width to ensure uniform paving without reducing paving efficiency.

The spline-connected spline shaft 42 and spline sleeve 41 can satisfy the requirements of torque transmission and axial sliding at the same time, and the spline shaft 42 and the spline sleeve 41 adopt trapezoidal and inverted trapezoidal keys and pins, which can ensure that they are not stuck when conveying OGFC mixture.

A hydraulic rod 12 is provided on one side of each spline shaft 42, and the two ends of the hydraulic rod 12 are respectively hinged to the scraper 14 and the frame 15. The movement of the scraper 14 follows the spline shaft 42. When the length of the secondary auger roller changes, the two scrapers 14 undergo the same displacement, ensuring that the OFGC mixture will not overflow to a place where it is not necessary to lay; one end of the cylinder barrel and one end of the piston rod of the hydraulic rod 12 are both hingedly connected, and the rotating pair is adaptive so as to meet the requirement that the scraper 14 only undergoes horizontal displacement relative to the frame 15.

[0040] Advantageously, the main auger roller 43 is rotatably connected to the frame 15, a transmission gear 29 is fixedly disposed in the middle of the main auger roller 43, a driving gear 28 is meshed on one side of the transmission gear 29, and the driving gear 28 is fixedly disposed in the middle of the spline sleeve 41; a trapezoidal baffle 44 is disposed on the side of the driving gear 28 and the transmission gear 29 close to the driving module 11, the trapezoidal baffle 44 is fixedly connected to the frame 15, and the main auger roller 43 and the spline sleeve 41 are rotatably connected to the trapezoidal baffle 44 respectively. The trapezoidal baffle 44 isolates the transmission part, and a sealed bearing is disposed on its side, which does not affect the transmission of the main auger roller 43 and the auxiliary auger roller, and ensures that the OGFC mixture does not affect the gear transmission, wherein the driving gear 28 is powered by the motor inside the frame.

[0041] Advantageously, a feeding module is provided on the side of the driving module 11 away from the screed plate 13, and the feeding module includes a loading box 19, and the loading box 19 is fixedly arranged on the side of the frame 15 away from the crawler 23, and a conveyor belt 25 is provided on one side of the loading box 19, and the conveyor belt 25 is driven by two conveyor belt wheels 26, and the conveyor belt wheels 26 are detachably mounted on the frame 15, and a plurality of friction ribs are provided on the surface of the conveyor belt 25 away from the conveyor belt wheels 26. The screed plate 13 is a common component of an asphalt paver, and can be heated and vibrated to smooth the asphalt; the conveyor belt 25 is supported by special materials, and is composed of a plurality of metal plates hinged to each other, which is resistant to high temperature and not easy to get stuck, and the friction ribs ensure that the OGFC mixture will not slip when being transported, and a certain part of the material will not accumulate in the dead corner of the loading box 19 for a long time.

[0042] Advantageously, a lever 33 is provided on one side of the conveyor belt 25, and the lever 33 is rotatably set on a fixed rod 34, and the fixed rod 34 is fixedly connected to the frame 15. A connecting rod 31 and a rack 35 are respectively provided at both ends of the lever 33, and the connecting rod 31 and the rack 35 are respectively hinged to the lever 33 through waist-shaped holes; the connecting rod 31 is slidably connected to the frame 15, and the rack 35 is slidably connected to the frame 15, one side of the rack 35 engages with a pinion 36, and the pinion 36 is rotatably connected to the frame 15, and a baffle 37 is provided on one side of the pinion 36, and the baffle 37 is fixedly set on the rotating shaft of the pinion 36. The waist-shaped hole allows adaptive adjustment of the hinge point between the rack 35 and the connecting rod 31 within a certain range. When the lever 33 rotates, the hinge point will inevitably change, so as not to interfere with the normal judgment process. The distance between the fixed rod 34 and the connecting rod 31 is small, so that the displacement of the connecting rod 31 is amplified, thereby driving the baffle 37 to change position.

[0043] Advantageously, a tensioning wheel 38 and a limiting wheel 39 are rotatably provided on one side of the frame 15, and the tensioning wheel 38 and the limiting wheel 39 jointly drive the tensioning belt 16. A positioning roller 17 is provided on the side of the frame 15 away from the driving module 11, and the positioning roller 17 is fixedly arranged on a telescopic rod 30, and the telescopic rod 30 is slidably connected with the frame 15; the tensioning belt 16 is sleeved on one end of the positioning roller 17. The positions of the loading truck and the whole vehicle can be known through the positioning roller, and the driving state of the truck can be planned by judging the state of the tensioning belt 16.

OGFC mixtures of different weights on the upper surface of the conveyor belt 25 will cause the floating plate to have different positions. The position of the baffle 37 is directly adjusted by the real-time position of the floating plate, and the amount of feeding is determined by the change of unloading, so that there will be no accumulation of materials or shortage of materials, and the uniform laying of the OGFC layer is ensured.

[0045] Advantageously, the frame 15 is symmetrically arranged, with a tensioning wheel 38, a limiting wheel 39 and a tensioning belt 16 provided on both sides of the frame 15, and the two tensioning belts 16 are respectively located at both ends of the alignment roller 17; a guard plate 40 is fixedly provided on both sides of the frame 15, and the track wheel 27 is rotatably arranged on the guard plate 40.

[0046] Advantageously, a control panel 20 is provided on the side of the conveyor belt 25 close to the driving module 11, and the control panel 20 is rotatably set on a fixed frame 21, and the fixed frame 21 is fixedly set on the frame 15, and the control panel 20 is driven by a driving belt 22; a protective shell is provided on the outer side of the control panel 20 and the driving belt 22, and the protective shell is fixedly connected to the frame 15.

[0047] Working principle of the present invention:

[0048] OGFC asphalt is the abbreviation of open-graded anti-skid wear layer asphalt pavement. OGFC has a large porosity (generally between 17% for the alignment roller and 22% for the drive belt), which can significantly reduce the water mist, splashing and glare caused by surface water on the pavement, improve the driving safety of the pavement, and reduce driving noise. Since this pavement structure is a multi-void embedded skeleton structure, the pavement's ability to resist rutting deformation is improved.

[0049] Since OGFC mixtures use more coarse aggregates and less fine aggregates, aggregates are easy to heat up and it is difficult to control the temperature of aggregates. If the mixture temperature is too high, asphalt will easily flow, and if the temperature is too low, construction work will be difficult. Therefore, temperature control during construction is particularly important. It is critical to ensure the temperature of the mixture during construction. The mixture should be tightly covered during transportation. After the mixture is spread, the roller should follow the paver to roll it so that the mixture can be quickly formed to ensure the overall quality of the OGFC asphalt mixture pavement.

[0050] A drainage and noise reduction pavement, which comprises, from top to bottom, an OGFC surface layer, a graded crushed stone layer, a clean water sand cushion layer, a transverse drainage pipe, and a plain soil compaction layer; when paving, the pavement is evenly laid in reverse order from bottom to top;

[0051] The OGFC surface layer is composed of OGFC asphalt, and is paved in conjunction with a drainage and noise reduction pavement paving device and paving method of the present invention;

[0052] OGFC asphalt is produced in a mixing plant and transferred to a truck compartment. The drainage and noise reduction pavement paving equipment and paving method of the present invention enters the paving site, and the driving direction, i.e., the paving path, is perpendicular to the cross section of the road. The truck loaded with OGFC asphalt stops at one side of the loading box 19 of the present invention, and aligns its compartment with the loading box 19. The truck compartment is slowly lifted, and the OGFC asphalt slides down and slides into the loading box 19.

[0053] The operator operates the present invention in the driving module 11, controls the conveyor belt wheel 26 to rotate, and the conveyor belt wheel 26 drives the conveyor belt 25 to deliver the OGFC asphalt into the paving module, and then starts the crawler wheel 27, and the crawler wheel 27 drives the crawler belt 23, and the present invention slowly travels along the preset route. At this time, the truck cooperates with the present invention to travel synchronously at the same speed;

[0054] The rear tire of the truck abuts against the alignment roller 17. The spring in the telescopic rod 30 and the tension belt 16 made of elastic material make the truck wheel always abut against the alignment roller 17, but the truck will not hit the frame 15. Within the allowed range, the truck will always deliver the OGFC asphalt into the loading box 19. The tension wheel 38 provided on the tension belt 16 is provided with a sensor. The tension state of the tension belt 16 is judged by the sensor. When the tension state is in a natural state (that is, the truck wheel and the alignment roller 17 are not in contact), it is necessary to feedback to the truck driver to reduce the driving speed of the truck. When the tension state of the tension belt 16 is too loose, it is necessary to feedback to the truck driver to increase the driving speed of the truck. The truck driver corrects the driving speed in real time to ensure that the OGFC asphalt can be accurately put into the loading box 19.

[0055] The driving gear 28 is started, driving the transmission gear 29 to rotate, and the main auger roller 43 and the spline sleeve 41 rotate at the same time and in opposite directions; the main auger roller 43 drives the main auger blade 18 to rotate, the spline sleeve 41 drives the spline shaft 42 to rotate, and the spline shaft 42 drives the auxiliary auger blade 24 to rotate. Under the action of the main auger blade 18 and the auxiliary auger blade 24, the OGFC asphalt moves to both sides until it fills the position between the main auger blade 18 and the auxiliary auger blade 24;

[0056] The screed plate 13 is started to smooth the layer closest to the road surface (affected by the height of the screed plate 13 and the road surface, and can be adjusted), and the rest of the OGFC asphalt continues to move forward following the present invention; during this process, the hydraulic rod 12 is started to control the scraper 14 to move along the axis of the spline sleeve 41, and control the scraper 14 to approach or move away from the trapezoidal baffle 44, thereby controlling the paving width of the OGFC asphalt to meet the construction conditions of narrowing or widening the road; specifically, after the hydraulic rod 12 is started, the spline shaft 42 and the spline sleeve 41 slide, and the hinge points of the hydraulic rod 12 and the scraper 14 and the hydraulic rod 12 and the driving module 11 all undergo adaptive angle changes;

[0057] In order to prevent the OGFC asphalt from overflowing from the end of the scraper 14 and to ensure the gap after the OGFC layer is compacted, the driver controls the speed of the crawler wheel 27 to control the driving speed of the present invention so that the consumption and replenishment of the OGFC asphalt are in a balanced state;

[0058] OGFC asphalt slides unevenly from the inside of the truck compartment (due to the temperature and adhesion of the OGFC asphalt, the different falling heights of the material caused by the consumption of OGFC asphalt, and the friction between the OGFC asphalt and the compartment). OGFC asphalt often slides down in clumps, and the sliding amount and sliding time cannot be determined. The truck driver can control the lifting height of the truck compartment, which can only roughly control the sliding amount of OGFC asphalt.

[0059] When the conveyor belt 25 is not started, the OGFC asphalt on the conveyor belt 25 is in the shape of a small hill. When the conveyor belt 25 is started, the part that contacts the conveyor belt 25 under the action of the friction ribs first enters the paving module, and the part of the OGFC asphalt on the upper side of the hill is blocked by the baffle 37 and is spread out. When the OGFC asphalt on the bottom side of the hill enters the paving module, the part on the upper side that is blocked can contact the conveyor belt 25 and is thus fed into the paving module. When a large amount of OGFC asphalt falls into the loading box 19 in a short period of time, in order to prevent the OGFC asphalt on the top layer from being unable to contact the conveyor belt 25 for a long time due to the accumulation of OGFC asphalt and causing adhesion, the floating plate and the conveyor belt wheel 26 slide (conveying The belt 25 is subject to increased gravity), the conveyor belt 25 moves relative to the frame 15, the conveyor belt 25 drives the clamping strip 32 to move, the clamping strip 32 drives the lever 33 to rotate around the fixed rod 34, the lever 33 amplifies the displacement of the clamping strip 32, causing the rack 35 to slide along the frame 15 for a large distance (in this process, the waist-shaped holes at both ends of the lever 33 will be displaced with the rack 35 and the hinge point of the clamping strip 32, and no motion interference will occur), the rack 35 drives the pinion 36 to rotate, the pinion 36 drives the baffle 37 to rotate, the deflection degree of the baffle 37 can control the cross-sectional size of the path of the OGFC asphalt entering the paving module, and when the baffle 37 rotates to a horizontal state, the OGFC asphalt can pass through at the fastest speed;

[0060] When the speed of passing the OGFC asphalt increases, the level of the OGFC asphalt in the paving module will increase, and the driver can judge it with the naked eye and make an operation to increase the driving speed of the present invention, while the truck driver cooperates;

[0061] In addition, the driver also needs to observe in real time whether the levels of OGFC asphalt at the positions of the two auxiliary auger blades 24 are different. When there is an obvious difference in the levels of OGFC asphalt on both sides, observe through the rearview mirror whether the truck driver pours the OGFC asphalt crookedly (to the left or right in the loading box 19). When the driver finds that the OGFC asphalt has fallen into the middle position of the loading box 19, the driver starts the drive belt 22 to control the control panel 20 to swing, and guide the OGFC asphalt to the left or flow, thereby solving the interference caused by the truck driver's misoperation.
