DETAILED DESCRIPTION

[0026] The following is a combination of specific implementation cases and attached Figures 1 to 4 The present invention is further described below, but the present invention is not limited to these embodiments.

[0027] Regarding the problem that asphalt grouting has not been vibrated in the gap, the natural settlement of asphalt will easily cause local depression in the grouting area, affecting the final flatness of the asphalt grouting and the overall stability after grouting, please refer to Figures 1 to 4 As shown, a highway construction and maintenance device is proposed, including a shell 1, springs 2 are vertically connected to the left and right sides of the inner cavity of the shell 1, and a lifting platform 3 is installed at the bottom end of the spring 2. When the lifting platform 3 moves downward under the action of an external force, the spring 2 can be forced to undergo elastic deformation. When the external force on the lifting platform 3 is removed, the lifting platform 3 can be moved upward with the help of the elastic force of the spring 2, and the lifting platform 3 moves in the vertical direction through a limiting component; the limiting component includes a limiting groove 7 opened on the inner side wall of the shell 1 along the vertical direction, and a first limiting rod 8 is vertically installed in the inner cavity of the limiting groove 7. A moving block 9 is slidingly sleeved on the outer wall of the first limiting rod 8, and the moving block 9 is The moving block 9 is connected to the side wall of the lifting platform 3. When the lifting platform 3 moves, it can drive the moving block 9 to move along the outer wall of the first limit rod 8 to limit the moving direction of the lifting platform 3; to avoid the lifting platform 3 from deflecting during movement, the inner cavity of the shell 1 is rotatably installed with a rotating shaft 4 from front to back through a bearing, and a cam 5 is eccentrically installed on the outer wall of the rotating shaft 4. The cam 5 rotates and fits with the upper surface of the lifting platform 3. The bottom end of the lifting platform 3 is connected to a vibration component for knocking on the ground to vibrate the ground. A motor 6 is installed on the front side of the outer wall of the shell 1. The output end of the motor 6 is connected to the rotating shaft 4. The motor 6 is turned on to drive the rotating shaft 4 and the cam 5 to rotate circumferentially;

[0028] The specific steps of realizing the compaction component to compact the ground are: the rotating shaft 4 and the cam 5 are driven to rotate circumferentially by the turned-on motor 6. When the distal side of the cam 5 moves to fit the upper surface of the lifting platform 3, the lifting platform 3 is prompted to move downward. At this time, the spring 2 is stretched. When the proximal side of the cam 5 rotates to fit the upper surface of the lifting platform 3, the lifting platform 3 is prompted to move upward under the elastic pulling action of the spring 2, thereby realizing the reciprocating lifting and lowering movement of the lifting platform 3, so as to drive the compaction component set at the bottom of the lifting platform 3 to perform synchronous lifting and lowering movement, and the compaction component intermittently knocks the ground to compact the asphalt in the inner cavity of the ground gap to avoid subsequent natural sedimentation of the asphalt.

[0029] See also Figure 2As shown, the compaction assembly includes a fixed seat 10 installed at the bottom end of the outer wall of the lifting platform 3, and two mounting plates 12 are symmetrically installed on the front and rear sides of the inner cavity of the fixed seat 10. A spring damper 14 is vertically installed at the bottom end of the outer wall of the mounting plate 12. The spring damper 14 is a commonly used component in the existing market. Its model can meet the use of this application and will not be described here. A compaction plate 15 is installed at the bottom end of the spring damper 14. Through the setting of the spring damper 14, the spring damper 14 can not only drive the compaction plate 15 to the ground for normal compaction under the action of external force, but also avoid the compaction plate 15 from rigidly contacting the ground, thereby protecting the compaction plate 15 and extending the service life of the compaction plate 15.

[0030] See also Figure 2 and Figure 3 As shown, a lead screw 11 is rotatably installed on the inner cavity of the fixed seat 10 from front to back through a bearing, and threads in opposite directions are symmetrically arranged on the front and rear sides of the outer wall of the lead screw 11. Two mounting plates 12 are respectively threadedly sleeved on the front and rear sides of the outer wall of the lead screw 11. When the lead screw 11 rotates, the two mounting plates 12 can be prompted to move synchronously toward or relative to each other; two second limit rods 13 are fixedly installed on the inner cavity of the fixed seat 10 from front to back, and the mounting plates 12 are slidably sleeved on the outer walls of the two second limit rods 13. When the mounting plates 12 move, they can move in the front and rear directions under the limiting action of the second limit rods 13 without skewing or twisting.

[0031] See also Figure 2 As shown, the second mounting seat 17 and the first mounting seat 16 are respectively installed at the bottom ends of the left and right side walls of the shell 1, and the second mounting seat 17 and the first mounting seat 16 are respectively installed at the bottom ends of the outer walls thereof with universal wheels 18, and the overall movement of the equipment can be realized through the universal wheels 18; a connecting rod 19 is vertically installed at the bottom end of the outer wall of the second mounting seat 17, and a scraper 20 is installed at the bottom end of the connecting rod 19. After the asphalt is filled and the asphalt is vibrated, as the shell 1 moves to the right, the scraper 20 at the bottom end of the connecting rod 19 is prompted to scrape the asphalt at the grouting position, so that the plane after the asphalt grouting is flush with the ground, thereby ensuring the neatness and stability of the road surface after the grouting; the scraper 20 is provided with inclined open ports from left to right, and the excess asphalt scraped off is accumulated at the open port of the scraper 20, which is convenient for subsequent centralized cleaning.

[0032] The working principle of a highway construction and maintenance device in this embodiment is as follows:

[0033] When the housing 1 moves to the right, the motor 6 is turned on to drive the rotating shaft 4 and the cam 5 to rotate circumferentially. When the distal side of the cam 5 moves to fit the upper surface of the lifting platform 3, the lifting platform 3 is forced to move downward. At this time, the spring 2 is stretched. When the proximal side of the cam 5 rotates to fit the upper surface of the lifting platform 3, the lifting platform 3 is forced to move upward under the elastic pulling action of the spring 2, thereby realizing the lifting and reciprocating movement of the lifting platform 3, so as to drive the fixed seat 10 and the vibration plate 15 set at the bottom end of the lifting platform 3 to synchronously lift and reciprocate, so as to vibrate the asphalt in the inner cavity of the ground gap between the two vibration plates 15 to prevent the subsequent natural sedimentation of the asphalt;

[0034] During the lifting and lowering process of the lifting platform 3, the moving block 9 connected to the outer wall of the lifting platform 3 can be lifted and lowered along the outer wall of the first limiting rod 8, so as to enable the lifting platform 3 to move stably in the vertical direction without deflection;

[0035] When the width of the ground gap changes and the distance between the two vibration plates 15 needs to be adjusted, the screw 11 is driven to rotate, so that the two mounting plates 12 symmetrically arranged on the front and rear sides of the outer wall of the screw 11 and threadedly sleeved move relative to or toward each other, so as to adjust the distance between the two mounting plates 12, and then adjust the distance between the vibration plates 15 connected to the bottom ends of the front and rear spring dampers 14;

[0036] After the asphalt is filled and vibrated, as the housing 1 moves to the right, the scraper 20 at the bottom of the connecting rod 19 is prompted to scrape the asphalt at the grouting joint, so that the plane after the asphalt grouting joint is flush with the ground, ensuring the neatness and stability of the road surface after the grouting joint;

[0037] The utility model is provided with two corresponding front and rear vibration plates 15, which can evenly and intermittently knock and compact the ground, and vibrate the asphalt in the gap, so as to avoid the problem of surface depression caused by subsequent natural sedimentation of asphalt, thereby ensuring the flatness of the surface after grouting and the overall stability of the grouting position, and no depression will appear after scraping. In addition, the distance between the front and rear two groups of vibration plates 15 can be adjusted, so that the distance between the two vibration plates 15 is adapted to the vibration processing requirements of road gaps of different widths, and the equipment is more versatile.

[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
