Description

Technical Field

[0001] The invention relates to the technical field of municipal road paving, in particular to a construction road surface paving device for municipal roads. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. When paving a road, a certain amount of asphalt is first sprayed on the road, and then a roller is used to roll it in a straight line to keep the road surface flat.

[0003] When using rollers to roll road asphalt materials, due to the high viscosity of asphalt materials, loose asphalt particles are easily attached to the surface of the rollers. As time goes by, the asphalt particles attached to the surface of the rollers gradually increase and form a mass. The existing cleaning of road leveling equipment is generally done after the road operation is completed. Failure to clean the equipment in time not only easily causes an increase in asphalt material attachments on the equipment, resulting in material waste, but also a large amount of asphalt attachments are easily accumulated, which easily causes bulges on the surface of the roller mechanism, so that the ground is easily sunken during subsequent rolling, reducing the work efficiency. In addition, paved roads generally require that the ground is free of debris. However, the construction environment of municipal roads is harsh. Under the influence of human and natural environmental factors, obstacles of different sizes and materials are easily retained on the road surface. The retention of obstacles on the road surface not only easily affects the increase in the accumulation height of the unloaded asphalt material, making it difficult to judge the feed amount, but also affects the compaction effect of the subsequent asphalt material, and also reduces the road paving effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides a bearing platform, a distance adjusting member, a discharge chamber, a rolling mechanism and a roadblock removal mechanism. Before the device is operated, the pressure rod is pressed downward to force the pressure rod to twist into a straight line. The middle section of the pressure rod is pressed downward, the retaining ring is pressed against the spring group and compressed, the bearing platform is forced to sink, and the feeding chamber, the rolling mechanism and the roadblock removal mechanism provided on the bearing platform are all sunk synchronously and attached to the ground. When paving the road, the feeding chamber is close to the ground, so as to reduce the splashing of asphalt outside the paving area when spraying, and force the rolling mechanism and the roadblock removal mechanism to stick to the ground, so that the asphalt material on the ground can be rolled in time and the road obstacles can be cleared in time, thereby improving the working efficiency.

[0016] 2. The present invention sets a rolling mechanism, and a driving motor drives the worm to rotate. The thread on the outside of the worm is engaged with the two groups of worm wheels, thereby synchronously driving the two groups of worm wheels, the rotating rod and the pressure rollers to rotate synchronously. The two groups of pressure rollers roll and level the raised asphalt blocks or material piles on the ground directly. During the rotation of the pressure rollers, the support sheets of the adjacent friction rollers are in close contact, and the support sheets scrape the asphalt particles on the surface of the pressure rollers to clean the pressure rollers, reduce the waste caused by excessive asphalt material on the surface of the pressure rollers, and indirectly cause uneven road surface rolling, thereby improving work efficiency.

[0017] 3. The present invention sets up a roadblock clearing mechanism, which is used in conjunction with the rolling mechanism. The scraper frame 1 pushes the ground debris in a straight line along the moving direction of the driving vehicle, forcing the area where the feeding chamber passes to reduce the debris, and then the worm is used to drive the half gear to rotate, and the gear 1 meshing with the half gear rotates in the opposite direction, thereby driving the rotation of the rotating shaft and the rotating plate. When the rotating plate rotates counterclockwise, the two groups of scraper frames 2 push the remaining debris accumulated on the road surface to the two sides of the driving vehicle respectively. The multi-angle road cleaning method can effectively push and clear the obvious or protruding roadblocks on the road surface in the driving area of ​​the feeding chamber, keep the paved road surface clean, not only reduce the impact on the accumulation height of the asphalt material discharged, but also reduce the impact on the subsequent compaction effect of the asphalt road surface, and further improve the road paving effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0029] See also Figure 1-8 As shown, a construction road paving device for municipal roads comprises a driving vehicle 1, a rectangular sinking trough 2 is provided at the upper bearing surface of the driving vehicle 1, and a bearing platform 3 is embedded and slidably connected inside the sinking trough 2, and a distance adjusting member 4 is provided on the upper end surface of the bearing platform 3, a feeding cavity 5 is provided in the middle section of the bottom surface of the bearing platform 3, a rolling mechanism 6 is provided through the upper end surface of the bearing platform 3 near one side, a rectangular opening groove 7 is provided on the other side of the upper end surface of the bearing platform 3, and a roadblock clearing mechanism 8 is provided inside the opening groove 7;

[0030] Among them, the limiting blocks 31 are fixedly installed at the centers of the front and rear end surfaces of the bearing platform 3, and the two groups of limiting blocks 31 are respectively slidably connected to the inside of the limiting grooves 32 opened at the centers of the front and rear inner walls of the sinking tank 2, and a gravity spring group 33 is arranged between the bottom surface of the limiting block 31 and the bottom inner wall of the limiting groove 32;

[0031] The distance adjusting member 4 includes a vertical rod 41, which is fixedly mounted on the upper end surface of the driving vehicle 1 at the center of one side of the sinking tank 2, and a vertical plate 42 is fixedly mounted on the upper end surface of the driving vehicle 1 at the center of the other side of the sinking tank 2. An inclined pressure rod 43 is hinged on the top of the vertical rod 41, and a support rod 44 is fixedly mounted at the center of the upper end surface of the supporting platform 3, and two groups of clamping rings 45 are arranged near the top at the front and rear ends of the support rod 44. The pressure rod 43 passes through between the two groups of clamping rings 45 in an inclined state, and the higher end of the pressure rod 43 is rotatably connected to a limiting rod 46, and one end of the limiting rod 46 passes through the vertical rod 41. Inside the card slot 47 opened in the middle section of the top of the plate 42, and the higher end of the limit rod 46 passes through the card slot 47 and is fixedly installed with a card 48, and a snap ring 49 is provided at the front and rear ends of the slot 47 near the upper and lower ends on the side of the vertical plate 42 away from the push rod 44. The front and rear adjacent groups of snap rings 49 are in a row, and are divided into two upper and lower rows. A cross bar 410 is fixedly installed at the center of a side of the vertical plate 42 near the push rod 44, and the push rod 44 passes through the inside of the cross bar 410, and a spring group 411 is provided between the cross bar 410 and the snap ring 45 outside the push rod 44.

[0032] During operation, the driving vehicle 1 is first pushed to the paved road surface, and the vehicle body is placed at the starting end of the road section. When the driving vehicle 1 moves, the material is sprayed by the discharge chamber 5 and the rolling mechanism 6 is used to roll the road surface. In this process, the pressure rod 43 is first pressed downward to force the pressure rod 43 to twist into a straight line. The middle section of the pressure rod 43 presses the pressure rod 44 downward, and the clamping ring 45 presses the spring group 411 to compress. The bearing platform 3 sinks under the force, and the limit block 31 slides down along the inside of the limit groove 32 and forces the gravity spring group 33 to compress. At this time, the feeding chamber 5, the rolling mechanism 6 and the roadblock removal mechanism 8 set on the bearing platform 3 all sink synchronously and stick to the bottom surface. After determining the position of the bearing platform 3, the limit rod 46 moves with the pressure rod 4 3, and one end thereof descends together and slides down along the card slot 47 until the card 48 descends to the bottom of the two groups of snap rings 49 at the bottom, and then the limit rod 46 can be rotated to 90 degrees, forcing the card 48 to be placed horizontally and clamped at the bottom of the two groups of snap rings 49, thereby limiting the pressure rod 43 to prevent the pressure rod 43 from tilting and affecting the stability of the bearing platform 3 when sinking; the setting of the distance adjusting member 4 not only facilitates the feeding chamber 5 to be close to the ground during road paving, thereby reducing the splashing of asphalt outside the paving area during spraying, but also forces the rolling mechanism 6 and the roadblock clearing mechanism 8 to be close to the ground, which can timely roll the asphalt material on the ground and timely clear the road obstacles, thereby effectively improving the road paving efficiency. Example 2

[0033] See also Figure 4 and Figure 5 As shown, the rolling mechanism 6 includes a rectangular storage frame 61, the bottom of the storage frame 61 is open, and the upper and lower ends of the storage frame 61 extend to the outside of the supporting platform 3 respectively, a worm 62 is arranged at the center of the inner wall of both sides of the storage frame 61, and the two ends of the worm 62 extend to the outside of the storage frame 61 and are located at the upper end of the supporting platform 3, one end of the worm 62 is fixedly connected to the driving motor 63, and the other end is fixedly installed with a half gear 64, a side surface of the storage frame 61 is located at the lower end of the half gear 64 and is installed with a gear 1 66 through a rotating shaft 65, and one end of the rotating shaft 65 passes through the half gear 64 and is connected to the roadblock clearing mechanism 8, and the bottom surface of the half gear 64 is meshed with the top of the gear 1 66. Two groups of rotating rods 67 are arranged inside the storage frame 61 at the middle section of the bottom of the worm 62. The front and rear inner walls of the two groups of rotating rods 67 are rotatably connected to the front and rear inner walls of the storage frame 61 respectively. Worm wheels 68 are fixedly installed at the middle sections of the two groups of rotating rods 67 and at the corresponding upper and lower positions of the worm 62. The two groups of worm wheels 68 are respectively meshed with the worm 62 for transmission. Pressure rollers 69 are fixedly installed outside each group of rotating rods 67 and at the front and rear ends of the worm wheels 68. The diameter of the pressure roller 69 is 3 cm larger than the diameter of the worm wheel 68, and the bottom of the pressure roller 69 extends to the outside of the storage frame 61. Friction rollers 610 are provided inside the storage frame 61 and near the lower end of the side of the two groups of pressure rollers 69 away from each other, and the front and rear ends of the friction rollers 610 rotate with the front and rear inner walls of the storage frame 61 respectively. A plurality of groups of inclined support pieces 611 are fixedly installed at equal distances on the outside of each group of friction rollers 610, one group of support pieces 611 is in contact with the outer wall of the adjacent pressure roller 69, and the two groups of friction rollers 610 are symmetrical with the two groups of pressure rollers 69 as the center.

[0034] During operation, the feeding chamber 5 spreads the material along the running direction of the driving vehicle, and the rolling mechanism 6 following closely rolls and levels the asphalt material everywhere. When the rolling mechanism 6 is in use, the driving motor 63 is first started, which drives the worm 62 to rotate, and the threads on the outside of the worm 62 are engaged with the two sets of worm wheels 68, thereby synchronously driving the two sets of worm wheels 68, the rotating rod 67 and the pressure roller 69 to rotate synchronously, so that the two sets of pressure rollers 69 roll and level the raised asphalt blocks or material piles on the ground directly; when the pressure rollers 69 are in a rolling section, the pressure rollers 69 are in a rolling section, and ... After a period of time, a small amount of asphalt particles will adhere to its surface. Since the asphalt material is relatively viscous, more attachments will stick to and gather on the surface of the pressure roller 69. In order to reduce the excessive adhesion of asphalt to the pressure roller 69 and affect the subsequent rolling effect and cause waste of asphalt particles, the pressure roller 69 is close to the support piece 611 of the adjacent friction roller 610 during its rotation. The support piece 611 scratches the asphalt particles on the surface of the pressure roller 69, thereby keeping the surface of the pressure roller 69 free of debris, which is beneficial to improving road paving efficiency and the smoothness of the road surface. Example 3

[0035] During the road paving process, due to the harsh construction environment, obstacles of different sizes and materials are likely to remain on the unpaved road surface, which are easily mixed in the asphalt material, affecting the flattening and compacting effect of the asphalt. By setting up the roadblock removal mechanism 8, obstacles are cleared on the road surface in the paving area, thereby improving the road paving effect;

[0036] See also Figure 6 - Figure 8 As shown, the roadblock removal mechanism 8 includes a scraper frame 81, which is fixedly installed at an opening on one side of the opening groove 7, and the bottom of the scraper frame 81 is a conical structure and is arranged to have a toothed surface, and a sliding groove 82 is provided on a side of the scraper frame 81 close to the inside of the opening groove 7. The roadblock removal mechanism 8 also includes two groups of sliding frames 83, which are respectively arranged at the center of the opening groove 7 near both sides. Two groups of scraper frames 84 are slidably connected inside the two groups of sliding frames 83. The front and rear groups of scraper frames 84 are located at the lower ends of the two groups of sliding frames 83. The two groups of scraper frames 84 and the two groups of sliding frames 83 are arranged to intersect in a cross, and the top surfaces of the scraper frames 84 are fixedly installed with snap rings 3 85 near two points. The two groups of snap rings 3 85 are respectively sleeved inside the two groups of sliding frames 83, and a spring damping shock absorber 86 is fixedly installed between each group of snap rings 3 85 and the inside of the sliding frame 83 adjacent to itself. The bottom of the scraper frame 84 is a conical structure and penetrates to the lower end of the opening groove 7. One end of the scraper frame 84 is slidably connected to the inside of the sliding groove 82. A push plate 87 is fixedly installed at the middle section of the top surface of the two groups of scraper frames 84, and a rotating piece 88 is commonly provided between the two groups of push plates 87. The center of one side of the rotating piece 88 is fixedly connected to the rotating shaft 65, and the upper and lower ends of the rotating piece 88 are curved. An inclined push rod 89 is intersected with one side of the rotating piece 88 near the upper and lower ends, and the other ends of the two groups of push rods 89 are respectively hinged to the center of one side of the front and rear groups of push plates 87.

[0037] During the paving process, the obstacle removal mechanism 8 is arranged at the front end of the running direction of the feeding chamber 5, and the obstacle removal mechanism 8 is used to clear the obstacles on the road surface before paving; first, when the driving vehicle 1 moves, the scraper frame 1 81 pushes the ground debris in a straight line along the moving direction of the driving vehicle 1, forcing the area where the feeding chamber 5 passes to reduce the debris, and then the worm 62 is used to drive the half gear 64 to rotate, and the gear 1 66 meshing with the half gear 64 rotates in the opposite direction, thereby driving the rotation of the rotating shaft 65 and the rotating plate 88. When the rotating plate 88 rotates counterclockwise, the two groups of push rods 89 at the upper and lower ends thereof respectively push the two groups of push plates 87 and the associated scraper frame 2 84 to the front of the opening groove 7 respectively. The rear end moves, and the top snap ring 3 85 of each set of scraper frame 2 84 moves along the inside of the sliding frame 83 and presses the corresponding spring damping shock absorber 86 to form a compression state. The two sets of scraper frame 2 84 push the remaining debris accumulated on the road surface to the two sides of the driving vehicle 1 respectively. When the teeth of the half gear 64 rotate to a position away from the gear 1 66, the gear 1 66 loses the meshing of the half gear 64 and stops rotating. At this time, the rotating shaft 65 and the rotating plate 88 also stop rotating and stop pressing the two sets of scraper frame 2 84, and then the spring damping shock absorber 86 rebounds and resets to force the two sets of scraper frame 2 84 to reset, thereby the push plate 87 and the rotating plate 88 are reset at the same time, which is convenient for subsequent use;

[0038] This multi-angle road cleaning method can effectively push and clear obvious or protruding obstacles on the road surface in the driving area of ​​the feeding chamber 5, keep the paved road surface clean, not only reduce the impact on the accumulation height of the unloaded asphalt material, but also reduce the impact on the subsequent compaction effect of the asphalt road surface, further improving the road paving effect.

[0039] Working principle:

[0040] When the present invention is used, the driving vehicle 1 is first pushed to the paved road, and the vehicle body is placed at the starting end of the road section. The pressure rod 43 is pressed downward to force the pressure rod 43 to twist into a straight line. The middle section of the pressure rod 43 presses the pressure rod 44 downward, and the clamp ring 45 presses the spring group 411 to compress. The bearing platform 3 is forced to sink, and the feeding chamber 5, the rolling mechanism 6 and the roadblock removal mechanism 8 arranged on the bearing platform 3 are all synchronously sunk and attached to the ground. When the road is paved, the feeding chamber 5 is close to the ground, so as to reduce the splashing of asphalt outside the paving area when spraying, and force the rolling mechanism 6 and the roadblock removal mechanism 8 to stick to the ground, so that the asphalt material on the ground can be rolled in time and the road obstacles can be cleared in time;

[0041] Next, the driving motor 63 is started, and the scraper frame 1 81 pushes the debris on the ground in a straight line along the moving direction of the driving vehicle 1, forcing the area where the feeding chamber 5 passes to reduce the debris, and then the worm 62 is used to drive the half gear 64 to rotate, and the gear 1 66 meshing with the half gear 64 rotates in the opposite direction, thereby driving the rotation of the rotating shaft 65 and the rotating plate 88. When the rotating plate 88 rotates counterclockwise, the two groups of push rods 89 at the upper and lower ends thereof respectively push the two groups of push plates 87 and the associated scraper frame 2 84 to move toward the front and rear ends of the opening groove 7 respectively, and the top clamp ring 3 85 of each group of scraper frame 2 84 moves along the inside of the sliding frame 83 and presses the corresponding spring damping shock absorber 86 to a compressed state, and the two groups of scraper frames 2 84 respectively push the remaining debris accumulated on the road surface to the two sides of the driving vehicle 1 to keep the road surface in the paving area clean;

[0042] Furthermore, the driving motor 63 drives the worm 62 to rotate, and utilizes the external thread of the worm 62 to mesh with the two sets of worm wheels 68, thereby synchronously driving the two sets of worm wheels 68, the rotating rod 67 and the pressure roller 69 to rotate synchronously, so that the two sets of pressure rollers 69 roll the raised asphalt blocks or material piles on the ground to directly level them; after the pressure roller 69 has rolled for a period of time, a small amount of asphalt particles will adhere to its surface. Since the asphalt material is relatively viscous, more attachments will stick to the surface of the pressure roller 69. In order to reduce excessive asphalt adhesion to the pressure roller 69 and affect the subsequent rolling effect and cause waste of asphalt particles, the pressure roller 69 is close to the support sheet 611 of the adjacent friction roller 610 during its rotation, and the support sheet 611 scratches the asphalt particles on the surface of the pressure roller 69 to clean the pressure roller 69.
