Description

Technical Field

[0001] The utility model relates to the technical field of cold-mix emulsified asphalt paving, in particular to a cold-mix emulsified asphalt paving box. Background Art

[0002] Cold mix cold paving technology has become one of the important ways to achieve low-carbon transportation due to its advantages of saving energy, protecting the environment, and reducing construction costs. Micro surfacing, as a representative preventive maintenance technology of cold mix cold paving, has been widely promoted and applied in the preventive maintenance of asphalt pavements on highways in my country due to its advantages of fast construction, short curing cycle, and low cost. However, after the construction of micro surfacing, the driving noise is large, the driving comfort is poor, and it is easy to fall off in the high humidity environment of the tunnel. The actual service life is 2 to 3 years, which is difficult to further adapt to the requirements of preventive maintenance technology. Cold mix ultra-thin overlay is a preventive maintenance technology for asphalt pavements with a certain structural layer thickness. It can effectively improve the anti-skid performance and flatness of asphalt pavements, and at the same time, it can treat and repair the mobility rutting of the pavement, and restore the service function of the pavement to a large extent. It successfully overcomes the problems of high noise and poor durability of micro surfacing technology. At the same time, compared with hot (warm) mix asphalt mixture, it effectively avoids the large consumption of energy and environmental pollution during the heating process of asphalt and mineral materials, as well as the asphalt aging problem caused.

[0003] The traditional micro-surfacing paving box has a scraper installed on the rear plywood of the paving box (with a tractor pulling it in front). The disadvantage of this is that during the paving process, the scraper has a large elasticity and deformation effect. If it encounters uneven road sections such as ruts and potholes, the scraper itself will exert a certain elastic pressure on the road surface, causing the paved road surface to fail to meet the flatness requirements. For example, ruts will be formed in places where there are ruts under the pressure of the scraper. In addition, due to the elastic effect of the scraper during the paving process, a part of the coarser graded particles will have a band-like supporting effect on the scraper, thereby producing more transverse ripples.

DETAILED DESCRIPTION

[0025] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] like Figure 1-8 As shown, the present embodiment provides a cold-mix emulsified asphalt paving box, which includes a tractor and a paving box 1 connected to the tractor chain, the paving box 1 is located behind the tractor in the direction of travel and extends in a direction perpendicular to the direction of travel of the tractor, a paving board 2 is rotatably installed on the bottom of the paving box 1 on the side away from the tractor, and a smoothing plate 3 is also floatingly arranged on the side of the paving board 2 away from the paving box 1, and the smoothing plate 3 can reciprocate along the extension direction of the paving box 1 during the movement of the tractor, the smoothing plate 3 is inclined and the higher side of the smoothing plate 3 faces the paving board 2 and is always separated from the paving board 2; the smoothing plate 3 is also fixedly provided with upwardly curved arc-shaped transition edge plates 4 on both sides of the reciprocating direction, and the tractor, as in the prior art, can be installed with a mixing box on it to directly mix the paving material, and then directly introduce it into the paving box 1 for paving operations.

[0028] During paving, unlike the prior art, the present invention uses rotating paving board 2 to adjust the paving thickness. After adjustment, paving board 2 can scrape the paving material (i.e., emulsified asphalt mixture) so that there will be no excess paving material at the rear. At the same time, the smoothing plate 3 arranged at the rear reciprocates horizontally (i.e., reciprocates in a direction perpendicular to the direction of travel of the tractor) to smooth the surface layer. The resulting pull marks or ripples are smoothed out, so that no pull marks or ripples are left, and finally the surface layer after paving has a higher flatness, solving the problem of uneven surface. The problem in the prior art that large particles in the asphalt material may be pulled to form scratches or ripples, which may have an adverse effect on subsequent use is solved; specifically, the present embodiment also provides a method for paving using the system, that is, the mixed emulsified asphalt is paved using a paving box 1, the paving box 1 moves under the traction of a tractor to form a cover layer on the road surface behind the paving box 1, and the surface of the cover layer is smoothed synchronously behind the paving box 1, and the smoothing direction is perpendicular to the moving direction of the paving box 1; the thickness of the cover layer is 0.6-1.5 cm, The smoothing operation includes using the smoothing plate 3 to contact the surface of the overlay layer at an inclination angle of 1-3° and reciprocating in the direction of the smoothing operation. The inclination angle is the angle between the smoothing plate 3 and the horizontal plane in the paving direction. The smoothing plate 3 is set to be inclined, and the higher side is located at the front end in the travel direction. This can prevent the edge of the smoothing plate 3 from colliding with the paving material particles protruding from the surface of the overlay layer, resulting in the formation of transverse scratches or ripples perpendicular to the travel direction on the overlay. In a further exemplary embodiment, the higher side of the smoothing plate 3 is inclined and curved upward. The curved portion is configured to be an arc with a smooth transition, so that it can provide downward pressure when in contact with the protruding paving materials, and at the same time smooth it out in the transverse reciprocating motion (while smoothing is also moving forward for paving), thereby ensuring that the marks or ripples formed by paving are smoothed out and no new marks or ripples are generated; in more detail, the upwardly curved arc-shaped transition edge plates 4 configured on both sides of the smoothing plate 3 can also provide downward pressure similar to the curved portion when the smoothing plate 3 reciprocates in the transverse motion (in a direction perpendicular to the moving direction), so as to better smooth out the protruding paving materials.

[0029] In a further exemplary scheme, the inclination angle of the smoothing plate 3 is 1-3°, that is, it is slightly higher in front of the traveling direction, and the curved part is arranged to prevent the protruding paving material from flipping over to the top of the smoothing plate 3 (although the excess paving material will be restricted in front of the paving plate 2 after being scraped by the paving plate 2, but because the paving material has a certain elasticity, similar to the prior art, during the paving process, some paving material may be first pressed into the cover layer by the paving plate 2 (corresponding to the pressing plate in the prior art) and then move upward to protrude above the cover layer), thereby ensuring that the protruding part is smoothed under the action of downward pressure and lateral reciprocating.

[0030] In a further exemplary embodiment, a first mounting shaft 5 and a second mounting shaft 6 are rotatably mounted in parallel with each other in the extension direction of the paving box 1, and a first auger 7 and a second auger 8 with opposite rotation directions are fixedly mounted on both ends of the first mounting shaft 5, and a third auger 9 and a fourth auger 10 with opposite rotation directions are fixedly mounted on both ends of the second mounting shaft 6. Figure 4 As shown by the arrow in the figure, this is the moving direction of the paving material in the paving box 1 when the first installation shaft 5 and the second installation shaft 6 are in operation. First, a mixing tank is also provided on the tractor in front. The mixed paving material falls directly to the front of the middle section of the paving box 1, that is, between the first auger 7 and the second auger 8. The material is distributed to both sides through the first auger 7 and the second auger 8. At the same time, the paving box 1 moves forward. The paving material will cover the bottom of the paving box 1 and will be spread on the road surface through the lower edge of the paving board 2 below. More paving material on both sides will move to the middle driven by the third auger 9 and the fourth auger 10, so that the paving material in the paving box 1 can be spread more evenly.

[0031] In a further detailed exemplary scheme, similar to the prior art, the paving box 1 has slide bars 11 fixedly connected to the lower ends on both sides along its travel direction, and the slide bars 11 provide a contact basis between the paving box 1 and the road surface during its travel. Different from the prior art, the paving box 1 in this scheme is directly connected to the upper end surface of the slide bars 11, the paving plate 2 is located between the two slide bars 11, and the smoothing plate 3 is located behind the slide bars 11. During the reciprocating movement, the smoothing plate 3 does not contact the slide bars 11 to avoid collision; in more detail, the slide bar 11 is also similar to an upward curved arc at the end close to the tractor.

[0032] In a further detailed exemplary embodiment, Figure 1 , 2As shown, a first elastic plate 12 is connected to the outer wall of the bottom of the side of the paving box 1 facing away from the paving board 2, and the first elastic plate 12 is inclined downward and extends into the paving box 1. During the movement of the paving box 1, the paving box 1 may be displaced up and down due to uneven road surface. The first elastic plate 12 can maintain contact with the road surface, thereby preventing the paving material from escaping outward through the gap generated during the up and down displacement. In more detail, a second elastic plate 13 is also connected to the paving box 1, and the second elastic plate 13 is inclined downward and contacted with the first elastic plate 12, so that the second elastic plate 13 on the inside provides downward pressure so that the lower end of the first elastic plate 12 fits better with the road surface, thereby preventing the paving material from leaking. In more detail, the first elastic plate 12 and the second elastic plate 1 3 can be detachably connected, and wear-resistant rubber plates are used, which is convenient for subsequent replacement and maintenance, and the cost of use is also low; more specifically, the second elastic plate 13 can be directly connected to the inner wall of the paving box 1 by bolts 14, and a first connecting plate 15 is fixedly connected to the outer wall of the paving box 1, and a strip through groove is opened on the first connecting plate 15. The first elastic plate 12 passes through the strip through groove and the upper end is fixedly connected to a limiting plate 16. The first connecting plate 15 is also connected to a bolt 14 that extends laterally into the strip through groove and passes through the first elastic plate 12, thereby realizing the detachable connection of the first elastic plate 12. Specifically, the bolts 14 at the first elastic plate 12 and the second elastic plate 13 are both threadedly connected, which is convenient for disassembly and installation.

[0033] In a further detailed exemplary embodiment, Figure 1 , 5 As shown in Figure 8, the paving box 1 is provided with a paving board 2 on one side of which the lower end is fixedly connected with an arc-shaped plate 17 extending into the paving box 1, and a pair of first mounting plates 18 are also fixedly connected at both ends of the arc-shaped plate 17, and a third mounting shaft 19 is rotatably installed between the two first mounting plates 18, and a rotating cylinder 45 is fixedly connected to one side of the paving board 2, and the rotating cylinder 45 is fixedly sleeved on the third mounting shaft 19, and the other side of the paving board 2 rotates with the third mounting shaft 19, and the distance between the lower end surface of the two slide bars 11 increases or decreases; similarly, the first mounting shaft 5, the second mounting shaft 6 and the third mounting shaft 19 are respectively driven to rotate by the motor 20, and the third mounting shaft 19 is The shaft 19 drives the paving board 2 to rotate when rotating, and stops at a certain position, which limits the paving thickness. The arc plate 17 and the two first mounting plates 18 are equivalent to enclosing a space for the installation of the paving board 2, and the two ends of the space extend outside the paving box 1. At the same time, the paving box 1 and the corresponding two first mounting plates 18 are fixedly connected by the slide bar 11, so that the two sides of the paving board 2 can be flush with the inner wall of the paving box 1, so that all the paving materials can be paved through the bottom of the paving board 2. Furthermore, a recessed portion 21 can be provided on the end of the slide bar 11 close to the paving board 2, so that the paving board 2 can be set longer ( Figure 8(shown by the middle dotted line) to ensure that all paving materials can pass under the paving plate 2 to achieve paving;

[0034] In more detail, the lower end of the arc plate 17 is bent backward and the two sides are fixed to the two slide bars 11 respectively, so that the arc plate can also guide the paving material in the paving box 1. The upper end of the arc plate 17 in the paving box 1 makes the paving material move forward and obliquely downward, then move backward and obliquely downward into between the slide bars 11 below, and finally enter the working range of the paving board 2 at the rear to realize paving.

[0035] In a further exemplary scheme, the paving box 1 is also fixedly connected to a second mounting plate 22, to which a telescopic drive 23 is also fixedly connected, and the telescopic drive 23 has a telescopic end 24 parallel to the extension direction of the paving box 1, and the telescopic end 24 is fixedly connected to a fourth mounting shaft 25, and a limiting roller 26 is also fixedly sleeved on the fourth mounting shaft 25, and a pair of limiting rings 27 are also fixedly connected to the roller surface of the limiting roller 26, and a floating ring 28 surrounding the limiting roller 26 is also arranged between the two limiting rings 27, and the floating ring 28 is a vertically arranged long strip ring structure and the lower end is also rotatably connected to the smoothing plate 3 through a first connecting rod 29, and the floating ring 28 is always located between the two limiting rings 27 during the operation of the telescopic drive 23.The overlay layer formed after paving is higher than the original road surface, and the floating ring 28 can adapt to the lifting of the smoothing plate 3 (it can be moved upward). During the smoothing, the telescopic drive 23 runs (the frequency of the reciprocating of the smoothing plate 3 does not need to be too high, and the speed of the tractor is not fast, ensuring that the surface of the overlay layer can be smoothed once by the smoothing plate 3 during the travel process, so the telescopic drive 23 can be a telescopic cylinder) to drive the limit roller 26 and the limit ring 27 to reciprocate, and the floating ring 28 is clamped between the two limit rings 27, so it also reciprocates together. More specifically, the second mounting plate 22 is also fixedly mounted with a first vertical plate 30 and a second vertical plate 31, and the telescopic drive 23 is fixedly mounted on the first vertical plate 30. , the telescopic end 24 passes through the first vertical plate 30 and is fixed to the fourth mounting shaft 25, and the fourth mounting shaft 25 is telescopically passed through the second vertical plate 31, so that the limiting roller 26 reciprocates between the first vertical plate 30 and the second vertical plate 31, driving the lower smoothing plate 3 to reciprocate. In more detail, two sets of limiting rollers 26 and corresponding first connecting rods 29 can be set, and a mounting frame 32 is fixedly installed on the smoothing plate 3, and two corresponding first mounting seats 33 are fixedly installed on the mounting frame 32 for the two first connecting rods 29 to rotate and install respectively, thereby driving the smoothing plate 3 to reciprocate more smoothly; in a further scheme, a pair of guide plates 34 are also fixedly connected to the fourth mounting plate, and the two guide plates 34 are located between the fourth mounting shaft 25 and the paving box 1, The two guide plates 34 are also provided with inclined guide holes 35, with the higher end of the guide holes 35 facing the paving box 1, and a cross bar 36 is provided between the two guide holes 35, and the cross bar 36 is also fixedly connected to a second connecting rod 37, and the second connecting rod 37 is also rotatably connected to a second mounting seat 38 fixedly mounted on the mounting frame 32. When the smoothing plate 3 encounters a raised paving material, the higher side of the smoothing plate 3 can be lifted up to ensure that the raised part smoothly enters under the smoothing plate 3, and then in the subsequent reciprocating process, the raised part is smoothed and pressed into the cover layer in a transverse reciprocating manner. The second connecting rod 37 and the cross bar 36 can assist in making the floating ring 28 float up and down more smoothly; in particular, the guide hole 35 is provided with a large width, Regarding the diameter of the cross bar 36, the two guide holes 35 restrict the cross bar 36 from being detached from it, and the corresponding second connecting rod 37 is also arranged obliquely, and the internal width of the floating ring 28 is slightly larger than the limiting roller 26, to ensure that the smoothing plate 3 does not encounter too much resistance when it is upward. In this way, the limiting ring 27 can be set smaller, and the floating ring 28 can be clamped to prevent the floating ring 28 from having a larger relative displacement with the limiting roller 26 in the lateral direction, that is, the smoothing plate 3 can be reciprocated synchronously; in particular, the length of the smoothing plate 3 in the reciprocating direction can be greater than the paving plate 2, so that the cover layer can be completely covered during the reciprocating process, and can also be smaller than the paving plate 2, so that the cover layer can be covered by increasing the reciprocating amplitude.

[0036] like Figure 1 ,3 As shown, the tractor and the paving box 1 are connected by a chain, and the tractor tows the paving box 1 forward through a connecting chain 44. More specifically, a pair of second connecting plates 39 are fixedly connected to the outer wall of the paving box 1 on one side close to the tractor, and a threaded cylinder 40 is fixedly connected to the second connecting plate 39, and the threaded cylinder 40 is provided with a notch 41 opening upward on the side facing the tractor, and also includes a third connecting rod 42 cooperating with the two threaded cylinders 40, and the middle section of the third connecting rod 42 is sunken to form an annular connecting portion 43, and the connecting chain 44 includes two corresponding ones, and one end is respectively wrapped around the connecting portion 43 and does not protrude outside the circle where the third connecting rod 42 is located (that is, the circle formed by the surrounding is located between the outer circle of the connecting portion 43 and the outer circle of the third connecting rod 42), the other end of the connecting chain 44 is pulled out through the notch 41 to connect with the tractor, and the third connecting rod 42 is threadedly connected to the threaded cylinder 40, thereby locking the connecting chain 44 on the second connecting plate 39, and the tractor can tow the paving box 1 forward through the connecting chain 44.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
