Description

Technical Field

[0001] The utility model relates to the technical field of road surface compaction, in particular to a steel slag asphalt concrete road surface compaction device. Background Art

[0002] Steel slag asphalt concrete is a kind of concrete that is broken in a special way. Steel slag is used as the aggregate in the asphalt concrete pavement to replace the traditional stone aggregate. Since steel slag has porous physical characteristics, it has very good adhesion to asphalt; therefore, using steel slag as aggregate can improve the strength of asphalt concrete; the structure of steel slag asphalt concrete is relatively stable and can maintain a long service life under different temperature, humidity and climate conditions. Therefore, steel slag asphalt concrete is widely used in highway construction, airport runway construction, large parking lot construction and other fields.

[0003] The local repair project of steel slag asphalt concrete pavement is to remove the damaged filler at the local location where the pavement is severely damaged, and use new steel slag asphalt concrete to repair it. In the prior art, when filling the repaired pavement, due to the small repair area, the cost of using heavy-duty leveling equipment to flatten the pavement petroleum asphalt concrete is high; therefore, the repaired pavement is usually compacted manually using a flat shovel or a hand-held rammer; however, this compaction method is inefficient, has poor results, and is time-consuming and labor-intensive.

[0004] To solve the above problems, various rammers are disclosed in existing patents, such as a road compacting rammer disclosed in Chinese utility model patent with authorization publication number CN220813310U, a frog-type rammer disclosed in Chinese utility model patent with authorization publication number CN206752444U, and a frog-type rammer disclosed in Chinese utility model patent with authorization publication number CN205975572U; the rammers disclosed in the above patents have basically the same principles, that is, an eccentric flywheel is driven to rotate by a motor, and the rotation drives the rammer vertically to the road surface to achieve road surface compaction. However, this type of rammer has a defect, that is, when the eccentric flywheel rotates, it not only drives the rammer to move up and down, but also drives it forward passively; and this type of rammer is hand-held, so when the user operates it, the rammer swings forward, driving the user's arm to swing forward, which has a greater impact on the user's arm; it also requires the user's arm to exert a greater force to control the rammer to prevent it from swinging forward too much and hitting the road surface in a jumping manner, thereby making the road surface incompletely compacted. Therefore, this type of rammer is more difficult to operate and requires a higher strength from the user. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a steel slag asphalt concrete pavement compacting device, which solves the problem that the existing rammer has a large impact on the user's arm during operation.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A steel slag asphalt concrete pavement compacting device comprises a compacting vehicle body, a tamping mechanism, a double flywheel mechanism and a driving mechanism; the compacting vehicle body is provided with a tamping mechanism movably; the top of the tamping mechanism is provided with a double flywheel mechanism, the bottom of the tamping mechanism is provided with a driving mechanism, and the driving mechanism and the double flywheel mechanism are connected in transmission;

[0008] The driving mechanism includes a first gear plate and a second gear plate, and tooth grooves are provided on opposite sides of the first gear plate and the second gear plate; a driving gear is provided between the first gear plate and the second gear plate, and the first gear plate and the second gear plate are respectively meshed and connected with the driving gear; the driving gear is drivingly connected with the output shaft of the driving motor, and the driving motor is arranged at the bottom of the tamping mechanism;

[0009] The double flywheel mechanism comprises a first eccentric flywheel and a second eccentric flywheel, which are respectively connected to the first gear plate and the second gear plate in driving connection; the center of gravity of the first eccentric flywheel and the second eccentric flywheel in the initial position is respectively located directly below their respective eccentric positions.

[0010] In the present scheme, the driving motor drives the first gear plate and the second gear plate to rotate simultaneously through the driving gear, and the rotation directions are opposite; therefore, when the first gear plate and the second gear plate drive the first eccentric flywheel and the second eccentric flywheel to rotate respectively, the rotation modes of the first eccentric flywheel and the second eccentric flywheel are also opposite; the impact forces of the tamping mechanism driven to swing upward and downward in reverse rotation can add to each other, while the impact forces of the forward swing and backward swing in reverse rotation can offset each other, which makes the tamping mechanism pound the road surface with a larger amplitude in the vertical direction and a stronger pounding impact force; the force in the horizontal direction is smaller, so the impact on the user's arm is smaller during operation, and it is more convenient to use; and there is no need to apply force to control the tamping mechanism to swing forward during operation, which is more labor-saving.

[0011] Furthermore, the tamping mechanism includes two side upright plates, each of which is provided with slide rails on both sides, and the side upright plates are movably connected to the compacting vehicle body through the slide rails; compacting plates are connected to the bottoms of the two side upright plates.

[0012] In this solution, the compaction plate is used to increase the contact area between the bottom of the tamping mechanism and the road surface to increase the road surface compaction efficiency.

[0013] Furthermore, the first gear plate and the second gear plate are rotatably connected to the bottom of the two side vertical plates through two gear shafts respectively; the first eccentric flywheel and the second eccentric flywheel are rotatably connected to the top of the two side vertical plates through two flywheel shafts respectively; the gear shaft and the flywheel shaft are connected through a belt transmission mechanism.

[0014] In this solution, the first gear plate and the second gear plate are both rotatably connected to the side plate through the gear shaft, so that the first gear plate and the second gear plate are connected to the side plate as a whole. During tamping operation, the gravity of the first gear plate and the second gear plate is also used to compact the road surface. This design enables the tamping mechanism to exert greater force on the road surface.

[0015] Furthermore, two bearing seats are provided between the two side plates, and bearings are installed in the two bearing seats; the two gear shafts are rotatably connected to the two bearing seats through the two bearings respectively.

[0016] In this solution, the two bearing seats support the two gear shafts respectively to ensure the stability of the first gear plate and the second gear plate during tamping work.

[0017] Furthermore, the compacting vehicle body includes a front vehicle body and a rear vehicle body, the front vehicle body is slidably connected to a slide rail on one side of the side stand; the rear vehicle body is slidably connected to a slide rail on the other side of the side stand;

[0018] The bottoms of the front vehicle body and the rear vehicle body are both provided with running wheels.

[0019] In this solution, the travel wheels are designed to easily push the device to move as a whole so as to pound and compact different locations.

[0020] Furthermore, a lug plate is fixedly connected to the front end of the rear vehicle body, and a limit plate is rotatably connected to the lug plate.

[0021] In this solution, during operation, the limit plate is rotated to a position parallel to the front edge of the rear vehicle body without affecting the up and down movement of the tamping mechanism; after the work is completed, the limit plate is rotated to a position perpendicular to the front edge of the rear vehicle body to limit the tamping mechanism so that the tamping mechanism is suspended in the air so as not to affect the overall movement of the device.

[0022] Furthermore, a bulldozer is provided at the front end of the front vehicle body, and the bulldozer is arranged to be inclined upward along the traveling direction of the compacting vehicle body.

[0023] In this solution, a bulldozer is designed at the front end of the front vehicle body to flatten the unevenness of the road surface to facilitate tamping and compaction by the tamping mechanism at the rear.

[0024] Furthermore, a handrail is provided at the rear end of the rear vehicle body.

[0025] The beneficial effects of the utility model are:

[0026] The steel slag asphalt concrete pavement compacting device provided by the utility model adopts a double eccentric flywheel design, and the two eccentric flywheels rotate in opposite directions, and the centers of gravity of the initial positions of the rotation are all below their respective eccentric positions, so when the two rotate, they start to rotate to both sides from the lowest point of the center of gravity, and the centers of gravity of the two meet at the highest point, and then continue to rotate to the lowest point to complete a swing cycle. Therefore, the impact forces of the two driving the tamping mechanism to swing upward and downward in the reverse rotation are mutually additive, and the impact forces of the two swinging forward and backward in the reverse rotation are mutually offset, which makes the tamping mechanism beat the road surface with a larger amplitude in the vertical direction and a stronger tamping impact force; the force acting on the tamping mechanism in the horizontal direction is small, so the impact on the user's arm is small during operation, and it is easier to use. In addition, compared with the tamping machine using an eccentric flywheel in the prior art, the tamping mechanism of the utility model will not swing forward in a jumping manner when tamping the ground, so the user does not need to apply force to control the forward swing of the tamping mechanism during operation, and the operation is more convenient and labor-saving.

For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all inventions and creations conceived using the utility model are protected.

[0035] like Figure 1 As shown, this embodiment provides a steel slag asphalt concrete pavement compacting device, which is used to pound and compact the pavement in a small-scale pavement filling project; the pavement compacting device adopts a double eccentric flywheel design, and the swings generated in the horizontal direction during the rotation of the two eccentric flywheels will offset each other, thereby reducing the impact on the user's arm, and the operability is strong; it specifically includes:

[0036] Compacting vehicle body 1, tamping mechanism 2, double flywheel mechanism 3 and driving mechanism 4;

[0037] Among them, a tamping mechanism 2 is movably arranged on the compacting vehicle body 1; a double flywheel mechanism 3 is arranged on the top of the tamping mechanism 2, and a driving mechanism 4 is arranged on the bottom of the tamping mechanism 2, and the driving mechanism 4 and the double flywheel mechanism 3 are transmission-connected.

[0038] The tamping mechanism 2 includes two side plates 21, a compacting plate 22 and a slide rail 23. Slide rails 23 are provided on both sides of each side plate 21. The side plates 21 are movably connected to the compacting vehicle body 1 through the slide rails 23. The bottom of the two side plates 21 is connected with a compacting plate 22, and the compacting plate 22 is used to increase the contact area between the bottom of the tamping mechanism 2 and the road surface, so as to increase the road surface compaction efficiency.

[0039] like Figure 2 As shown, the driving mechanism includes a first gear plate 41, a second gear plate 42, a driving gear 43 and a driving motor 44; the first gear plate 41 and the second gear plate 42 are rotatably connected to the bottom of the two side vertical plates 21 through two gear shafts 45 respectively; the first gear plate 41 and the second gear plate 42 are provided with tooth grooves on the opposite sides; a driving gear 43 is provided between the first gear plate 41 and the second gear plate 42, and the first gear plate 41 and the second gear plate 42 are respectively meshed and connected with the driving gear 43; the driving gear 43 is transmission-connected to the output shaft of the driving motor 44, and the driving motor 44 is arranged at the bottom of the tamping mechanism 2.

[0040] The double flywheel mechanism 3 includes a first eccentric flywheel 31, a second eccentric flywheel 32 and a flywheel shaft 33. The first eccentric flywheel 31 and the second eccentric flywheel 32 are rotatably connected to the tops of the two side panels 21 through two flywheel shafts 33 respectively; the first eccentric flywheel 31 and the second eccentric flywheel 32 are respectively connected to the first gear plate 41 and the second gear plate 42; the center of gravity of the first eccentric flywheel 31 and the second eccentric flywheel 32 at the initial position is located directly below their respective eccentric positions. The gear shaft 45 and the flywheel shaft 33 are connected through a belt transmission mechanism 5, which is a conventional mechanism for mechanical transmission. For the specific structure, see Figure 2 .

[0041] The driving motor 44 drives the first gear plate 41 and the second gear plate 42 to rotate simultaneously through the driving gear 43, and the rotation directions are opposite; therefore, when the first gear plate 41 and the second gear plate 42 drive the first eccentric flywheel 31 and the second eccentric flywheel 32 to rotate respectively, the rotation modes of the first eccentric flywheel 31 and the second eccentric flywheel 32 are also opposite; the impact forces of the tamping mechanism 2 to swing upward and downward in the reverse rotation are added to each other, while the impact forces of the two to swing forward and backward in the reverse rotation are offset to each other, which makes the tamping mechanism 2 pound the road surface with a larger amplitude and stronger pounding impact force in the vertical direction; the force acting on the tamping mechanism 2 in the horizontal direction is smaller, so the impact on the user's arm is smaller during operation, and it is more convenient to use; and there is no need to apply force to control the tamping mechanism 2 to swing forward during operation, and the operation is more labor-saving.

[0042] Two bearing seats 46 are also arranged between the two side plates 21, and bearings are assembled in the two bearing seats 46; the two gear shafts 45 are rotatably connected to the two bearing seats 46 through two bearings respectively; the two bearing seats 46 support the two gear shafts 45 respectively to ensure the stability of the first gear plate 41 and the second gear plate 42 during the tamping work.

[0043] The compacting vehicle body 1 includes a front vehicle body 11 and a rear vehicle body 12. The front vehicle body 11 is slidably connected to a slide rail 23 on one side of a side vertical plate 21; the rear vehicle body 12 is slidably connected to a slide rail 23 on the other side of the side vertical plate 21; the bottom of the front vehicle body 11 and the rear vehicle body 12 are both provided with running wheels 13, which can easily push the device to move as a whole so as to hammer and compact different positions.

[0044] like Figure 3 As shown, an ear plate 15 is fixedly connected to the front end of the rear body 12, and a limit plate 16 is rotatably connected to the ear plate 15. During operation, the limit plate 16 is rotated to a position parallel to the front end edge of the rear body 12 without affecting the up and down movement of the tamping mechanism 2; after the work is completed, the limit plate 16 is rotated to a position perpendicular to the front end edge of the rear body 12 to limit the tamping mechanism 2 so that the tamping mechanism 2 is suspended in the air so as not to affect the movement of the entire device.

[0045] A bulldozer 14 is provided at the front end of the front body 11, and the bulldozer 14 is inclined upward along the traveling direction of the compacting body 1; the bulldozer 14 is designed at the front end of the front body 11 to flatten the unevenness of the road surface to facilitate the tamping mechanism 2 behind to compact it.

[0046] A handrail 17 is provided at the rear end of the rear vehicle body 12 .

[0047] The working principle of this embodiment is:

[0048] When the steel slag asphalt concrete pavement compacting device provided in this embodiment is used, it is pushed by the handrail 17 to move to the road surface that needs to be compacted; the limit plate 16 is rotated to a position parallel to the front edge of the rear vehicle body 12, so that the tamping mechanism 2 can fall to the ground; and preparations are made to start the tamping work.

[0049] The driving motor 44 is started, and the driving motor 44 drives the first gear plate 41 and the second gear plate 42 to rotate simultaneously through the driving gear 43. The first gear plate 41 and the second gear plate 42 respectively drive the first eccentric flywheel 31 and the second eccentric flywheel 32 to rotate.

[0050] At the beginning of rotation, the positions of the first eccentric flywheel 31 and the second eccentric flywheel 32 are as follows: Figure 1 or Figure 2 As shown, at this time, the centers of gravity of the first eccentric flywheel 31 and the second eccentric flywheel 32 are both directly below their respective eccentric positions; therefore, when the two rotate, they rotate from the lowest point of the center of gravity to both sides, as shown in FIG. Figure 4 shown.

[0051] In the middle of the rotation, the center of gravity of the first eccentric flywheel 31 and the second eccentric flywheel 32 rotates to the highest point. Figure 5 As shown; and then continue to rotate to the lowest point to complete a swing cycle. Therefore, the impact forces of the first eccentric flywheel 31 and the second eccentric flywheel 32 swinging forward and backward in the reverse rotation offset each other, so the tamping mechanism 2 can only repeatedly pound and compact the road surface in the vertical direction.

[0052] Those skilled in the art will appreciate that the embodiments herein are intended to help readers understand the principles of the present invention, and should be understood that the protection scope of the present invention is not limited to such specific statements and embodiments.
