Technical Field

[0001] The invention relates to the technical field of road paving equipment, and in particular to road paving equipment for traffic engineering. Background Art

[0002] Road paving equipment mainly includes excavators, rollers, pavers, road repair machines, concrete mixers, etc. These equipment play an irreplaceable role in the road construction process to ensure the smooth progress of the project and the quality of the road.

[0003] Asphalt paver is a kind of heavy machinery specially used for road construction. It is mainly used to spread asphalt mixture evenly on the road base, and perform preliminary vibration and leveling. The following is a relevant introduction to asphalt paver: Classification by paving width: Asphalt paver can be divided into four categories according to paving width: small, medium, large and super large. Classification by walking mode: Asphalt paver can be divided into crawler type and tire type. Crawler type paver is suitable for uneven construction environment, while tire type paver is suitable for flat road construction. Asphalt paver is mainly composed of power unit, transmission system, walking device, feeding device and working device. Its working principle is to transport asphalt mixture to the spiral paver through the feeding device, and then the spiral paver distributes the material to the entire paving width, and finally pre-compacts and leveling through vibration and ironing device.

[0004] For example, the invention patent with announcement number CN111379209B provides a cement pavement paving and maintenance integrated machine for road construction.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0032] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a road paving equipment for traffic engineering, which is used to be installed on a road paving vehicle, and includes a housing 100, a paving mechanism and a feeding mechanism. The housing 100 is fixedly arranged on the road paving vehicle. The paving mechanism includes two augers 140, which are distributed in sequence along a first direction, and the two augers 140 are symmetrically arranged about the middle of the housing 100. The first direction is a horizontal direction, and the first direction is perpendicular to the moving direction of the road paving vehicle. Each augers 140 is arranged on the housing 100 along the first direction, and the augers 140 can rotate around their own axis, and the two augers 140 can approach and move away from each other along the first direction.

[0033] Along the first direction, the two ends of the auger 140 are respectively the first end and the second end, and the end where the two auger 140 are close to each other is the first end. The second end of each auger 140 is provided with a first hydraulic cylinder 130, and the first hydraulic cylinder 130 is arranged along the first direction, and one end of the first hydraulic cylinder 130 is ball-jointed with the housing 100. Each auger 140 can swing in the horizontal direction with the connection point of the first hydraulic cylinder 130 and the housing 100 as the center of the circle and the length of the first hydraulic cylinder 130 and the auger 140 along the first direction as the radius. The feeding mechanism is used to transport asphalt between the two augers 140.

[0034] During operation, the auger 140 rotates around its own axis while the two auger 140 move closer to or farther from each other along a first direction, and the auger 140 swings around the connection point between the first hydraulic cylinder 130 and the housing 100 .

[0035] The asphalt is first transported between the two augers 140 by the feeding mechanism. When the asphalt falls into the shell 100, it tends to form a cone on the ground and in the middle of the shell 100, and the point where the asphalt falls is the top of the cone. In the process of falling, the asphalt will be segregated, and large particles of asphalt will fall to the bottom of the asphalt pile. The swing of the first end of the auger 140 flattens the original cone-shaped asphalt pile, so that the pushed asphalt can be mixed with the large particles of asphalt, thereby reducing the impact of segregation on paving.

[0036] When there is a lot of asphalt accumulated on both sides of the outer shell 100 along the first direction, the auger 140 can pass through the materials accumulated on both sides of the outer shell 100 along the first direction while moving toward the two sides of the outer shell 100 along the first direction, and squeeze the excess asphalt on both sides of the outer shell 100 along the first direction back into the spiral blades 142. Then, as the auger 140 approaches the middle of the outer shell 100, the auger 140 transports the excess asphalt to the middle of the outer shell 100, thereby preventing the asphalt density on both sides of the outer shell 100 along the first direction from being too high, resulting in uneven overall density of the laid asphalt.

[0037] Along the first direction, when a large amount of asphalt accumulates in the middle of the outer shell 100, the auger 140 can accelerate the movement of the asphalt in the middle of the outer shell 100 toward both sides of the outer shell 100 along the first direction, thereby improving the conveying efficiency of the auger 140 and preventing the asphalt density in the middle of the outer shell 100 from being too high.

[0038] In this embodiment, the auger 140 includes a rotating shaft 141 and a spiral blade 142 . The rotating shaft 141 is arranged along a first direction, the spiral blade 142 is arranged along the first direction, and the spiral blade 142 is fixedly connected to the rotating shaft 141 .

A road paving equipment for traffic engineering also includes a first driving mechanism, and the first driving mechanism includes two driving components, each of which includes a base 151, a motor 152, a first gear 153 and a second gear 154. The base 151 is slidably arranged in the power box 120, and a bearing is fixedly arranged on one side of the base 151, and the axis of the bearing is arranged along the first direction, and the bearing is fixedly connected to the rotating shaft 141. The first gear 153 is fixedly arranged on the output shaft of the motor 152, and the second gear 154 is fixedly arranged on the rotating shaft 141, and the second gear 154 is meshed with the first gear 153.

[0040] The motor 152 is started, and the motor 152 drives the second gear 154 to rotate through the first gear 153, thereby driving the auger 140 to rotate. The two augers 140 rotate in different directions, and both transport the asphalt in the middle of the housing 100 to both sides of the housing 100 along the first direction.

[0041] In this embodiment, along the first direction, first slide grooves 121 are respectively provided on both sides of the power box 120, and the first slide grooves 121 are arranged along the second direction, the second direction is a horizontal direction, the second direction is perpendicular to the first direction, and the second direction is the moving direction of the road paving vehicle, and the rotating shaft 141 is slidably arranged in the first slide groove 121. The two sides of the housing 100 along the first direction are the first side and the second side, and the two sides of the housing 100 along the second direction are the third side and the fourth side.

[0042] In this embodiment, a road paving equipment for traffic engineering also includes a second driving mechanism, which includes a second hydraulic cylinder 122. The second hydraulic cylinder 122 is arranged along the second direction. One end of the second hydraulic cylinder 122 is fixedly connected to the power box 120. The other end of the second hydraulic cylinder 122 is fixedly provided with a connecting rod 123. The connecting rod 123 is arranged along the first direction. A hinged rod 124 is fixedly provided at both ends of the connecting rod 123. The hinged rod 124 is arranged along the second direction. One end of each hinged rod 124 is ball-jointed to a base 151.

[0043] The second hydraulic cylinder 122 is started, and the second hydraulic cylinder 122 is extended and shortened along the second direction. Since one end of the first hydraulic cylinder 130 is ball-jointed with the housing 100, one end of each articulated rod 124 is ball-jointed with a base 151, each auger 140 swings in the horizontal direction with the connection point of the first hydraulic cylinder 130 and the housing 100 as the center and the length of the first hydraulic cylinder 130 and the auger 140 along the first direction as the radius.

[0044] In this embodiment, the rotating shaft 141 includes a first connecting tube 143, a second connecting tube 144 and a first connecting shaft 145. The first connecting tube 143, the first connecting shaft 145 and the second connecting tube 144 are sequentially distributed along the direction from the first end to the second end of the auger 140, the first connecting tube 143, the first connecting shaft 145 and the second connecting tube 144 are all arranged along the first direction, the first connecting tube 143 is in the first slide groove 121, the first connecting shaft 145 and the second connecting tube 144 are fixedly connected, the first connecting shaft 145 can be slidably arranged in the first connecting tube 143 along the first direction, and the first connecting shaft 145 and the first connecting tube 143 can rotate synchronously.

[0045] When the first hydraulic cylinder 130 is started, the first connecting pipe 143 and the first connecting shaft 145 can move relative to each other, so that the rotating shaft 141 can be extended and retracted, and then the extension and contraction of the first hydraulic cylinder 130 can drive the two augers 140 to continuously move away from and closer to each other along the first direction.

[0046] In this embodiment, a plurality of second slide grooves are provided in the first connecting tube 143, and the plurality of second slide grooves are distributed along the circumference of the first connecting tube 143, and each second slide groove is arranged along the first direction. A plurality of protrusions 146 are fixedly provided on the first connecting shaft 145, and each protrusion 146 can be slidably arranged in a second slide groove along the first direction. The first connecting tube 143 and the first connecting shaft 145 can move relative to each other and can rotate synchronously.

[0047] In this embodiment, a ring block is fixedly provided at one end where the first hydraulic cylinder 130 and the auger 140 are connected, and a ring groove is provided in the second connecting pipe 144, in which the ring block is rotatably provided. The first hydraulic cylinder 130 drives the auger 140 to move synchronously, and the auger 140 can rotate relative to the first hydraulic cylinder 130.

[0048] In this embodiment, the feeding mechanism includes a hopper and a conveyor belt, the hopper is fixedly arranged on the road paving vehicle, and the hopper and the conveyor belt are sequentially distributed along the vertical direction. The conveyor belt is rotatably arranged on the road paving vehicle, and the conveyor belt is arranged along the second direction, one end of the conveyor belt is arranged at the lower end of the hopper, and the other end of the conveyor belt is located in the middle of the housing 100. A discharge channel connected to the conveyor belt is opened on the side of the housing 100 close to the road surface.

[0049] In this embodiment, a road paving equipment for traffic engineering further includes a compaction mechanism, which includes a screed plate 110 and a lower pressing plate 111. The screed plate 110 is arranged along the first direction, and the screed plate 110 is fixedly arranged on the road paving vehicle. The screed plate 110 is located at the rear side of the housing 100 along the traveling direction of the road paving vehicle. The lower pressing plate 111 is arranged along the first direction, and the lower pressing plate 111 is between the screed plate 110 and the housing 100. A third hydraulic cylinder is fixedly arranged on the lower pressing plate 111, and the third hydraulic cylinder is arranged vertically, and one end of the third hydraulic cylinder is fixedly connected to the paving side.

[0050] Working process: asphalt is put into the hopper, and the asphalt in the hopper falls to the middle of the shell 100 through the conveyor belt. The motor 152 is started, and the motor 152 drives the second gear 154 to rotate through the first gear 153, thereby driving the auger 140 to rotate. The two augers 140 rotate in different directions, and both convey the asphalt in the middle of the shell 100 to both sides of the shell 100 along the first direction. The auger 140 spreads the asphalt in the shell 100, and the spread asphalt falls onto the road surface from the discharge channel. During the movement of the paving vehicle, the lower pressure plate 111 continuously rises and presses down to pre-compact the asphalt on the road surface, and then the screed plate 110 levels the asphalt.

[0051] During the process of paving asphalt by the auger 140, the second hydraulic cylinder 122 is started, and the second hydraulic cylinder 122 is extended and shortened along the second direction. Since one end of the first hydraulic cylinder 130 is ball-jointed with the housing 100, one end of each articulated rod 124 is ball-jointed with a base 151, each auger 140 swings in the horizontal direction with the connection point of the first hydraulic cylinder 130 and the housing 100 as the center and the length of the first hydraulic cylinder 130 and the auger 140 along the first direction as the radius, and the first end of the auger 140 swings from the third side to the fourth side of the housing 100.

[0052] When the asphalt falls from the hopper, it tends to form a cone on the ground and in the middle of the shell 100, and the point where the asphalt falls is the top of the cone. In the process of falling, the asphalt will be segregated, so that large particles of asphalt gather around the auger 140. The large particles on the first and second sides of the shell 100 can be transported and moved by the auger 140, while the large particles falling on the third and fourth sides of the shell 100 will continue to accumulate. The swing of the first end of the auger 140 flattens the original cone-shaped asphalt pile, so that the pushed asphalt can be mixed with the large particles of asphalt, thereby reducing the impact of segregation on paving.

[0053] During the process of paving the asphalt by the auger 140, the first hydraulic cylinder 130 is started, thereby driving the two auger 140 to continuously move away from and approach each other along the first direction. When the asphalt on the first side and the second side of the shell 100 is relatively large, the auger 140 can pass through the materials accumulated on the first side and the second side during the process of moving toward the first side and the second side of the shell 100, and squeeze the excess asphalt on the first side and the second side back into the spiral blade 142, and then as the auger 140 approaches the middle of the shell 100, the auger 140 transports the excess asphalt to the middle of the shell 100. This prevents the asphalt density on the first side and the second side of the shell 100 from being too high, resulting in uneven overall density of the paved asphalt.

[0054] Along the first direction, when a large amount of asphalt accumulates in the middle of the outer shell 100, the auger 140 can accelerate the movement of the asphalt in the middle of the outer shell 100 toward the first side and the second side of the outer shell 100, thereby improving the conveying efficiency of the auger 140 and preventing the asphalt density in the middle of the outer shell 100 from being too high.

[0055] At the same time, the movement and swing of the auger 140 along the first direction can increase the transmission area. Specifically, when the auger 140 is tilted, that is, when the first end of the auger 140 is close to the third side and the fourth side of the housing 100, the movement of the auger 140 along the first direction drives the asphalt between the auger 140 and the housing 100, preventing the asphalt between the auger 140 and the housing 100 from accumulating in one place for a long time, causing the temperature to drop and adhesion to occur, thereby affecting the pavement paving effect, and helping to improve the paving quality.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
