Description

Technical Field

[0001] This utility model belongs to the field of airport asphalt road paving technology, and in particular relates to an airport asphalt pavement compaction device. Background Technology

[0002] Airport asphalt roads are runways within airports used for aircraft takeoff and landing. Unlike conventional roads, airport asphalt roads have more stringent construction requirements, including higher standards for road levelness, crack resistance, and deformation resistance.

[0003] During the paving of airport asphalt roads, after the asphalt material is initially laid by equipment such as bulldozers, operators need to perform fine spreading and leveling. Fine spreading and leveling are used to further flatten and compact the asphalt road.

[0004] Specifically, the construction process often requires multiple operators to work together. One operator uses tools like shovels to further spread the asphalt, while the other uses rollers to compact it. This compaction process often involves repeatedly rolling the asphalt back and forth in the same spot to achieve flattening. Therefore, due to the low level of automation, the required number of operators (i.e., manpower) is large, resulting in high paving costs. Consequently, current methods are relatively outdated in terms of both workload and efficiency.

[0005] Meanwhile, the drawbacks of manual fine paving are that, in order to ensure that the road is fully leveled and compacted, multiple repeated operations are often performed during the manual paving process, which further increases the workload. At the same time, the workload of subsequent repair and correction after manual fine paving is also relatively large, such as the need for secondary or even multiple compaction and leveling of areas that are not fully compacted.

[0045] Example 1

[0046] like Figures 1-5 As shown, an airport asphalt pavement compaction device includes end frames 1 spaced apart on both the front and rear sides; in order to increase the stability of the end frames 1, connecting beams 11 are welded between the end frames 1.

[0047] The asphalt residue spreading mechanism is rotatably connected between the end portions of the end frames 1, and a rolling mechanism is located inside the asphalt residue spreading mechanism; the asphalt residue spreading mechanism is located at the right end portion between the end frames 1. During operation, the asphalt residue spreading mechanism is used to spread the asphalt residue again which is not completely spread.

[0048] Specifically, the asphalt residue spreading mechanism comprises a rotating rod 21 rotatably connected between the end frames 1 (the front and rear ends of the rotating rod 21 are fixedly connected with rotating shafts, the rotating shafts are rotatably connected with bearing frames A, and the bearing frames A are fixedly installed on the bottom of the end frames 1).

[0049] Meanwhile, the rotating rod 21 is assembled with a spreading plate 22, the spreading plate 22 is adjusted on the rotating rod 21 through an adjusting structure, and the distance between the outer end of the spreading plate 22 and the rotating rod 21 can be adjusted through the adjusting structure.

[0050] Specifically, the rotating rod 21 is provided with a long sliding groove which is equal in length to the spreading plate 22; and the spreading plate 22 is slidingly connected in the long sliding groove.

[0051] The adjusting mechanism comprises adjusting sliding openings 211 provided at the top of the rotating rod 21 at the front and rear sides, the top of the spreading plate 22 is fixedly connected with screw rods 23 which penetrate through the adjusting sliding openings 211, and the screw rods 23 are threadedly connected with locking nuts 231.

[0052] During the adjusting process, the operator loosens the locking nuts 231 until the locking nuts 231 no longer press the top of the rotating rod 21, and then the operator slides the spreading plate 22 in the horizontal and left-right directions to adjust the distance between the right end of the spreading plate 22 and the rotating rod 21, that is, to adjust the length of the spreading plate 22 extending out of the right side wall of the rotating rod 21. For example, when the asphalt accumulation is large, the extending length is increased.

[0053] During the rotating process, the spreading plate 22 continuously spreads the accumulated asphalt, which facilitates subsequent rolling and compaction.

[0054] In order to improve the spreading effect of the material of the spreading plate 22, the two sides of the spreading plate 22 are integrally formed with inclined slope surfaces (which are convenient for embedding into the asphalt material) and a plurality of tooth structures 221 are integrally formed at the edge positions of the slope surfaces. The tooth structures 221 further assist the embedding into the material, which facilitates the spreading of the material.

[0055] Embodiment 2

[0056] As Figures 1-5As shown, the embodiment is based on the structure of embodiment 1, and the roller mechanism comprises a roller shaft 3 (the front and rear ends of the roller shaft 3 are fixedly connected with rotating shafts, the rotating shafts are rotatably connected with bearing frames A, and the bearing frames A are fixedly installed on the bottom of the end frame 1). The roller shaft 3 is used to preliminarily compact the paving asphalt.

[0057] Specifically, the rotating rod 21 and the roller shaft 3 are driven to rotate through the transmission structure. Specifically, according to the existing belt transmission mode, the transmission structure comprises a first driven pulley 41 installed on the rotating shaft position of the rotating rod 21; the transmission structure further comprises a second driven pulley 42 driven by a transmission belt, the second driven pulley is installed on the rotating shaft position of the roller shaft 3; the transmission structure further comprises a transmission motor 43, a driving pulley 431 is respectively installed on the output shaft of the transmission motor 43 and the second driven pulley 42, and the driving pulleys 431 are connected through a transmission belt; the transmission motor is fixedly installed on the top of the end frame 1.

[0058] During operation, under the driving of the motor, the driving pulleys 431 rotate, the second driven pulley 42 drives the first driven pulley 41 to rotate, and then the rotating rod 21, the material spreading plate 22 and the roller shaft 3 rotate, the former spreads the asphalt, and the latter preliminarily compacts the road.

[0059] In order to further increase the compaction degree of the road, the adjusting roller mechanism is installed between the end frames 1.

[0060] The adjusting roller mechanism is located on the left side of the roller mechanism, and specifically, the adjusting roller mechanism comprises an adjusting roller shaft 5, the front and rear ends of the adjusting roller shaft 5 are rotatably connected with end bearing frames 52, the top portions of the end bearing frames 52 are fixedly connected with a plurality of sliding adjusting screws 51 slidingly connected to the end frame 1, and the upper ends of the sliding adjusting screws 51 are threadedly connected with support adjusting nuts blocked on the top portion of the end frame 1.

[0061] During operation, the support adjusting nuts are loosened to slide downward to adjust the adjusting roller shaft 5, for example, when the compaction degree of the road is not enough (the roller shaft cannot completely and fully compact the asphalt material), the weight of the heavy adjusting roller shaft 5 is completely applied to the road, and for the case that the road is sufficiently compacted, the adjusting roller shaft 5 is lifted up to reduce the pressure of the adjusting roller shaft 5 pressing on the road, and after adjustment, the support adjusting nuts are adjusted downward to be supported on the end frame 1.

[0062] Embodiment 3

[0063] As Figures 1-5As shown, the airport asphalt pavement compaction device in the embodiment is based on the structure of the embodiment 1, and further comprises a vibrating and leveling mechanism (the vibrating and leveling mechanism is located at the left side of the adjusting roller mechanism) arranged between the tail portions of the end frame 1. The vibrating and leveling mechanism is supported by the adjusting nut to realize the last vibration and leveling of the road.

[0064] Specifically, the vibrating and leveling mechanism comprises a vibrating and leveling plate 6, and a vibrating motor 7 is fixedly installed at the top center of the vibrating and leveling plate 6 in the prior art manner; the vibrating and leveling plate 6 is fixedly installed at the bottom of the end frame 1 through spring structures at the top front and back sides thereof.

[0065] The spring structure 8 comprises fixed columns 82 fixedly connected at the bottom of the end frame 1 and the top of the vibrating and leveling plate 6 respectively, and a reinforcing spring 81 is sleeved between the fixed columns 82; the fixed columns 82 are arranged in a spaced manner (there are hollow portions in the spring cavities of the reinforcing spring 81). The two ends of the reinforcing spring 81 are fixedly connected to the end frame 1 and the vibrating and leveling plate 6 respectively.

[0066] Meanwhile, the outer side wall and the front and back side walls of the vibrating and leveling plate 6 are fixedly connected with upwardly bent inclined baffles 61 respectively (to avoid the asphalt residue from entering the vibrating and leveling plate 6 during the vibration process).

[0067] During the working process, under the action of the vibrating motor 7, the vibrating and leveling plate 6 in the vibrating state vibrates to level the road and simultaneously assists the compaction through the vibration.

[0068] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also be within the protection scope of the present application.
