Summary of the invention

[0006] The purpose of the present invention is to solve the shortcoming in the prior art that asphalt close to the ground is inconvenient to compact, and to propose an asphalt vibration compaction device and a method for using it for road and bridge construction.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an asphalt compaction device for road and bridge construction, comprising a casing, four fixed blocks are evenly fixedly installed inside the casing, and limiting rods are fixedly installed on the upper surfaces of the four fixed blocks.

[0010] The effect achieved by the above components is as follows: after the casing is moved to the asphalt pavement at the position where compaction is required, the automatic telescopic rod is started to retract. At this time, the two mutually fitting paddle plates will be inserted into the concrete floor to a certain depth. At this time, the vibration block inside the casing is started, and the vibration block will drive the pressure block to move downward. During the movement of the pressure block, the broken arms of the cross structure on the pressure block will squeeze the two paddle plates at the same time, and the pressure block will move relative to the inclined surfaces of the paddle plates, thereby realizing the opening of the two paddle plates.

In the present invention, by providing a toggle device, after the casing is moved to the asphalt pavement at the position where compaction is required, the automatic telescopic rod is started to retract, and at this time, the two mutually fitting toggle plates will be inserted into the concrete floor to a certain depth, and at this time, the vibration block inside the casing is started, and the vibration block will drive the pressing block to move downward, and in the process of the pressing block moving, the broken arm of the cross structure on the pressing block will squeeze the two toggle plates at the same time, and the pressing block will move relative to the inclined surface of the toggle plates, thereby realizing the opening of the two toggle plates. At this time, the opened toggle plates will push the asphalt materials at the two sides apart, and the pressing block will continue to move, thereby realizing the compaction of the asphalt floor after being pushed apart, and facilitating the compaction of the asphalt pavement that is inconvenient to compact inside. In the process of retracting the pressing block, the inclined surface of the terrace structure on the pressing block will generate vibration between the two toggle plates. The shifting plate will be reset by the elastic force of the No. 1 spring on the connecting strip, which is convenient for the subsequent work of pushing away the concrete material. In the process of pushing away the concrete material, most of the pushed away material will accumulate between the rotating plate and the shifting plate. When the vibration block is reset, the barbed strip on the rotating plate can push the pushed away material into the surface of the asphalt ground after the initial compaction, which is convenient for the secondary compaction of the asphalt pavement. The rotating plate will be quickly reset and vibrated by the elastic force of the No. 2 spring between the positioning block and the pressure strip, thereby improving the reset efficiency of the asphalt after pushing away.

At this time, the limiting work of the plate frame during rotation can be realized, which is convenient for using the plate frame to vibrate the upper layer of the asphalt ground, and the limit frame on the limit frame is pulled out from the upper side of the plate frame, and the ball is pulled, and the ball drives the pull rope to slide on the surface of the pulley, and the pulley has the effect of changing the direction of the pulling force of the pull rope, and the pull rope will drive the two plate frames to lift up, and at this time the pull rope is put on the inner wall of the limit bar, and the ball will be stuck on the upper side of the limit bar, and the support work of the lifted plate frame can be realized, which is convenient for the normal use of the toggle device, and the auxiliary device is set to facilitate the conversion of the vibration block structure, thereby facilitating the compaction work of different layered grounds.

[0035] 3. In the present invention, by providing a leveling device, after the asphalt pavement is initially compacted, the shovel frame with a herringbone structure is rotated to a position that is horizontal to the ground, and the rotating bolt is pressed against the surface of the inclined plate. At this time, the fixed work of the rotated shovel frame can be achieved. In the process of pushing the casing, the shovel frame will level the excess asphalt material on the asphalt ground, and the excess raw materials will flow from the reserved groove of the shovel frame into the position between the two baffles. The inner wall of the herringbone structure shovel frame will flatten the raw materials, thereby achieving the filling of the pits on the asphalt ground after leveling, thereby improving the repair effect of the asphalt ground.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0048] Embodiment 1, as Figure 1-9 As shown, the present invention provides an asphalt compaction device for road and bridge construction and a method for using the device, comprising a casing 1, four fixed blocks 3 are evenly fixedly installed inside the casing 1, limit rods 4 are fixedly installed on the upper surfaces of the four fixed blocks 3, vibration blocks 2 are slidably connected to the surfaces of the four limit rods 4, a buffer spring 5 is fixedly connected to the side where the vibration block 2 and the fixed block 3 are close to each other, a toggle device 6 is provided on the surface of the vibration block 2, an auxiliary device 7 is provided on the side wall of the vibration block 2, and a leveling device 8 is provided on the side wall of the casing 1.

[0049] The specific arrangement and functions of the shifting device 6, the auxiliary device 7 and the leveling device 8 will be described in detail below.

[0050] like Figure 3 and Figure 4As shown, the toggle device 6 includes a connecting strip 605 with toggle function, a round rod 606 and a toggle plate 608, a pressure block 601 with a driving function and a spring 607, a mounting block 602 with a supporting function, an automatic telescopic rod 603 and a universal wheel 604. By providing the toggle device 6, it is convenient to toggle and reset the asphalt material, and to facilitate the layered compaction of the asphalt floor, thereby improving the compaction efficiency of the asphalt floor and extending the service life of the asphalt pavement in the later stage.

[0051] The eight connecting strips 605 are all fixedly connected to the inner wall of the casing 1, and the eight connecting strips 605 are grouped in groups of four by four. The circular rod 606 is slidably connected to the inside of the connecting strip 605, the dial plate 608 is fixedly connected to the end face of the circular rod 606, and the side of the dial plate 608 close to the upper end is in a "V"-shaped structure, and the cross-section of the lower end of the dial plate 608 is a right-angled trapezoidal structure. The pressing block 601 is fixedly connected to the lower surface of the vibration block 2, the pressing block 601 is in a "cross" structure, and the cross-section of the lower side of the pressing block 601 is a step structure. The No. 1 spring 607 is sleeved on the surface of the circular rod 606, and the two ends of the No. 1 spring 607 are fixedly connected to the connecting strip 605 and the dial plate 608 respectively. The four mounting blocks 602 are all fixedly connected to the side wall of the casing 1, the automatic telescopic rod 603 is fixedly connected to the lower surface of the mounting block 602, and the universal wheel 604 is fixedly connected to the output end of the automatic telescopic rod 603. After the casing 1 is moved to the asphalt pavement at the position where compaction is required, the automatic telescopic rod 603 is started to retract. At this time, the two mutually fitting plates 608 will be inserted into the concrete floor to a certain depth. At this time, the vibration block 2 inside the casing 1 is started, and the vibration block 2 will drive the pressing block 601 to move downward. During the movement of the pressing block 601, the broken arms of the cross structure on the pressing block 601 will squeeze the two plates 608 at the same time, and the pressing block 601 will move relative to the inclined surface of the plates 608, thereby realizing the opening of the two plates 608. When the pressing block 601 is working, the opened paddle 608 will push the asphalt materials on both sides away, and the pressing block 601 will continue to move, so as to realize the compaction work of the asphalt ground after being pushed away, which is convenient for the compaction work of the asphalt road surface that is inconvenient to compact inside. In the process of retracting the pressing block 601, the inclined surface of the step structure on the pressing block 601 will move relative to the two paddle plates 608. At this time, the paddle plates 608 will receive the elastic force of the No. 1 spring 607 on the connecting strip 605 to reset, which is convenient for the subsequent work of pushing away the concrete material.

[0052] The side wall of the paddle plate 608 is fixedly connected with two fixing strips 610. A rotating plate 611 is rotatably installed on one side of the two fixing strips 610 close to each other. The rotating plate 611 is an arc-shaped strip structure, and a plurality of barbed strips are evenly arranged on the arc surface of the rotating plate 611. In the process of removing the concrete material, most of the removed material will accumulate between the rotating plate 611 and the paddle plate 608. When the vibration block 2 is reset, the barbed strips on the rotating plate 611 can push the removed material into the surface of the asphalt ground after the initial vibration, which is convenient for the secondary vibration of the asphalt pavement. The side wall of the paddle plate 608 is fixedly connected with two positioning blocks 612. The interiors of the two positioning blocks 612 are both slidably connected with the limit pin 613. The lower end of the limit pin 613 is fixedly connected with a pressure strip 614. The cross section of the pressure strip 614 is an "L"-shaped structure. The surface of the limit pin 613 is covered with a second spring 609. The two ends of the second spring 609 are respectively fixedly connected to the positioning block 612 and the pressure strip 614. The rotating plate 611 will be quickly reset and vibrate due to the elastic force of the No. 2 spring 609 between the positioning block 612 and the pressure strip 614, thereby improving the reset efficiency of the asphalt after being pushed away.

[0053] like Figure 3 and Figure 5 As shown, the auxiliary device 7 includes two auxiliary blocks 708, and the two auxiliary blocks 708 are fixedly connected to the side walls of the vibration block 2. The two auxiliary blocks 708 are internally slidably connected with a limit frame 701 in a "U" shape. The lower end of the limit frame 701 is fixedly connected with two limit frames 707 in a "U" shape. The side wall of the pressing block 601 is fixedly connected with two rotating shafts 705. The side walls of the two rotating shafts 705 are rotatably installed with a plate frame 704. The side wall of the plate frame 704 is fixedly connected with two convex strips, and the upper cross-section of the convex strips is a triangular structure. When the upper layer of the asphalt floor needs to be vibrated after the initial compaction of the asphalt floor, the plate frame 704 will be suspended on the rotating shaft 705 due to its own gravity, and the limit frame 707 on the limit frame 701 will be stuck on the upper side of the plate frame 704. At this time, the limit work of the plate frame 704 during rotation can be realized, which facilitates the use of the plate frame 704 to vibrate the upper layer of the asphalt floor, and the limit frame 707 on the limit frame 701 is pulled out from the upper side of the plate frame 704.

[0054] The side wall of the vibration block 2 is fixedly connected with a plate 702, and a pull rope 703 is slidably penetrated inside the plate 702. The lower end of the pull rope 703 has two branches, and the two branches at the lower end of the pull rope 703 are fixedly connected with a rotating pin 706. The rotating pin 706 is connected to the inside of the plate frame 704 for internal rotation. The upper end of the pull rope 703 is fixedly connected with a sphere 710. The side wall of the vibration block 2 is fixedly connected with a limit bar 709, and the limit bar 709 is an "L"-shaped structure. The pull rope 703 will drive the two plate frames 704 to lift up. At this time, the pull rope 703 is sleeved on the inner wall of the limit bar 709, and the sphere 710 will be stuck on the upper side of the limit bar 709. At this time, the support work of the lifted plate frame 704 can be realized, which facilitates the normal use of the toggle device 6. The side wall of the vibration block 2 is fixedly connected with two shafts 711, and the side wall of the shaft 711 is rotatably installed with a pulley 712. The ball 710 drives the pull rope 703 to slide on the surface of the pulley 712 , and the pulley 712 has the effect of changing the direction of the pulling force of the pull rope 703 .

[0055] like Figure 7 and Figure 8 As shown, the leveling device 8 includes two inclined plates 82, both of which are fixedly connected to the side wall of the housing 1. A rotating rod 86 is rotatably installed inside the two inclined plates 82, and a shovel frame 81 is fixedly connected to the side wall of the rotating rod 86. The cross section of the shovel frame 81 is a "human" structure. A plurality of reserved grooves 89 are opened on one side of the shovel frame 81, and two baffles 85 are fixedly installed on the inner wall of the shovel frame 81. After the initial vibration of the asphalt pavement, the shovel frame 81 with the "human" structure is rotated to a position that is horizontal to the ground. In the process of pushing the housing 1, the shovel frame 81 will level the excess asphalt material on the asphalt ground, and the excess raw materials will flow from the reserved groove 89 of the shovel frame 81 to the position between the two baffles 85. The inner wall of the shovel frame 81 with the herringbone structure will flatten the raw materials, thereby filling the pits on the asphalt ground after leveling, thereby improving the repair effect of the asphalt ground.

[0056] Both ends of the rotating rod 86 are fixedly connected to the connecting plate 83, and the internal thread of the connecting plate 83 is penetrated by a bolt 84. The bolt 84 is turned and pressed against the surface of the inclined plate 82, so that the shovel frame 81 can be fixed after rotation. The inner wall of the rotating rod 86 is slidably connected to a support bar 87, and the surface of the inclined plate 82 is fixedly connected to two rectangular bars 88. When the shovel frame 81 is not needed, the shovel frame 81 is rotated and lifted, and the support bar 87 inside the rotating rod 86 is slid, and the support bar 87 is stuck in the position between the two rectangular bars 88, so that the support work of the lifted shovel frame 81 can be achieved.

[0057] A method for using an asphalt compaction device for road and bridge construction comprises the following steps:

[0058] S1: The asphalt product is spread by using the spreading plate 608 in the spreading device to achieve preliminary compaction of the inner asphalt structure;

[0059] S2: The rotating plate 611 drives the asphalt to be reset by the elastic force of the second spring 609, which facilitates the compaction of the asphalt pavement of the upper structure;

[0060] S3: Using auxiliary devices to drive the rotating plate frame to work parallel to the ground, facilitating the normal compaction work of the upper structure asphalt pavement;

[0061] S4: The shovel frame 81 of the leveling device 8 facilitates the leveling or filling of the bumps and potholes on the asphalt road surface, thereby improving the efficiency of compacting the asphalt road surface.

[0062] The overall working principle is that after the casing 1 is moved to the asphalt pavement at the position where compaction is required, the automatic telescopic rod 603 is started to shrink, and at this time, the two mutually fitting plates 608 will be inserted into the concrete floor to a certain depth, and at this time, the vibration block 2 inside the casing 1 is started, and the vibration block 2 will drive the pressing block 601 to move downward, and during the movement of the pressing block 601, the broken arm of the cross structure on the pressing block 601 will squeeze the two plates 608 at the same time, and the pressing block 601 will move relative to the inclined surface of the plates 608, thereby realizing the opening of the two plates 608. At this time, the opened plates 608 will push the asphalt materials on both sides apart, and the pressing block 601 continues to move, so as to realize the compaction of the asphalt floor after being pushed apart, which is convenient for the compaction of the asphalt pavement that is inconvenient to compact inside. In the process of retracting the pressing block 601, the inclined surface of the terrace structure on the pressing block 601 will contact with the two plates 60 8, at this time, the paddle plate 608 will receive the elastic force of the No. 1 spring 607 on the connecting strip 605 to reset, which is convenient for the subsequent work of pushing away the concrete material. In the process of pushing away the concrete material, most of the pushed away material will be accumulated in the position between the rotating plate 611 and the paddle plate 608. When the vibration block 2 is reset, the barbed strips on the rotating plate 611 can push the pushed away material into the surface of the asphalt ground after the initial compaction, which is convenient for the secondary compaction of the asphalt road surface. The rotating plate 611 will be quickly reset and shaken by the elastic force of the No. 2 spring 609 between the positioning block 612 and the pressure strip 614, thereby improving the reset efficiency of the asphalt after being pushed away. By setting the paddle device 6, the pushing and resetting of the asphalt material is facilitated, the layered compaction of the asphalt ground is facilitated, thereby improving the efficiency of the compaction of the asphalt ground and extending the service life of the asphalt road surface in the later stage.

[0063] When the upper layer of the asphalt floor needs to be vibrated after the initial compaction of the asphalt floor, the ball 710 is taken out from the inner wall of the limit bar 709. At this time, the plate frame 704 will be suspended on the rotating shaft 705 due to its own gravity, and the limit frame 707 on the limit frame 701 is stuck on the upper side of the plate frame 704. At this time, the limit work of the plate frame 704 during rotation can be realized, which is convenient for using the plate frame 704 to vibrate the upper layer of the asphalt floor. The limit frame 707 on the limit frame 701 is pulled out from the upper side of the plate frame 704, and the ball 710 is pulled out. 10 will drive the pull rope 703 to slide on the surface of the pulley 712, and the pulley 712 has the effect of changing the direction of the pulling force of the pull rope 703. The pull rope 703 will drive the two plate frames 704 to lift up. At this time, the pull rope 703 is put on the inner wall of the limit bar 709, and the ball 710 will be stuck on the upper side of the limit bar 709. At this time, the support work of the lifted rear plate frame 704 can be achieved, which is convenient for the normal use of the toggle device 6. By setting the auxiliary device 7, the conversion work of the vibration block 2 structure is facilitated, and then the compaction work of different layered ground is facilitated.

[0064] After the initial compaction of the asphalt pavement, the shovel frame 81 of the herringbone structure is rotated to a position horizontal to the ground, and the bolt 84 is rotated to press against the surface of the inclined plate 82. At this time, the fixed work of the rotated shovel frame 81 can be achieved. In the process of pushing the casing 1, the shovel frame 81 will level the excess asphalt material on the asphalt ground, and the excess raw materials will flow from the reserved groove 89 of the shovel frame 81 into the position between the two baffles 85. The inner wall of the herringbone shovel frame 81 will flatten the raw materials, thereby filling the pits on the asphalt ground after leveling, thereby improving the repair effect of the asphalt ground. When the shovel frame 81 is not needed, the shovel frame 81 is rotated and lifted, and the support bar 87 inside the sliding rotating rod 86 is clamped in the position between the two rectangular bars 88. At this time, the support work of the lifted shovel frame 81 can be achieved. By setting the leveling device 8, the repair and filling work of the asphalt ground is facilitated, and the compaction effect of the upper asphalt ground is improved.
