Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a repairing and trimming device for road base paving construction. Background Art

[0002] With the acceleration of my country's urbanization process, road construction has become an important part of urban infrastructure construction. During the road base paving construction, the finishing and trimming device is mainly used to trim the edges of the base material after paving to ensure the flatness and beauty of the road surface.

[0003] The common device for trimming the edges of base materials is an edge scraper. The edge scraper is installed on the side of the paver. It is a multifunctional device used to scrape and trim the edges of base materials. It can remove excess material and keep the edges neat.

[0004] A grader shoulder slope repairing device is disclosed in Chinese Patent Publication No. CN220080134U. The grader shoulder slope repairing device can discharge excess materials to the bottom of the slope through the repairing device.

[0005] However, compared with the prior art in the related field, the prior art has the following defects: Poor construction continuity: Frequent manual processing of materials is often required, such as manually breaking up agglomerated materials, moving materials to appropriate locations, etc., or multiple additional equipment is required to sequentially complete material breaking up, moving and paving, resulting in frequent interruptions in the construction process, low overall construction efficiency, and extended road edge construction time; Uneven material mixing: It is difficult to fully mix materials at different locations. The quality of the edge of the road after repair may be unstable due to the original state of the materials (such as agglomeration in some areas and looseness in others). The durability of some areas is insufficient due to large differences in material composition, such as local peeling, looseness and other problems; Poor compaction effect: lack of effective loose material structure, uneven compaction due to inconsistent internal compactness of the material during the compaction process, resulting in cracks, potholes and other defects on the road edge, affecting the flatness and driving comfort of the road, and high maintenance costs in the later stage; Weak material adaptability: The ability to handle materials with different characteristics is limited. When faced with sticky materials that are easy to clump or materials with large particles and poor fluidity, it is difficult to effectively break them up and spread them evenly, which can easily cause problems such as material residue, accumulation or uneven paving thickness, and cannot meet the diverse needs of road construction.

DETAILED DESCRIPTION

[0021] 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.

[0022] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0023] An embodiment of a repairing and trimming device for road base paving construction of the present invention is as follows Figures 1 to 7 As shown, it includes a trimming scraper 1, a first rotating shaft 2 is rotatably provided on the front side of the top of the trimming scraper 1, the bottom end of the first rotating shaft 2 is connected to the second rotating shaft 4 through a universal transmission assembly 3, and a material dispersing assembly 5 is provided at the end of the second rotating shaft 4 away from the universal transmission assembly 3. A shaking component 6 is provided on the trimming scraper 1, and the shaking component 6 is used to control the material dispersing assembly 5 to tilt toward one side of the road and to tilt the front side; when the material dispersing assembly 5 rotates, the material dispersing assembly 5 can not only break up the agglomerated materials, but also bring the materials at the bottom of the slope to the top of the slope, and then evenly spread the materials from the top of the slope downward, and at the same time, the rotation of the material dispersing assembly 5 can also be used to preliminarily compact the slope, and the shaking of the material dispersing assembly 5 caused by the shaking of the shaking component 6 can be cooperated to improve the effect of the material dispersing assembly 5 in breaking up the agglomerated materials.

[0024] like Figures 1 to 3 As shown, a driving member 7 is fixedly installed on the top of the trimming scraper 1, and the output end of the driving member 7 is connected to the first rotating shaft 2. The driving member 7 is used to control the rotation of the first rotating shaft 2. A rotating hole is opened at the position of the trimming scraper 1 corresponding to the first rotating shaft 2. The first rotating shaft 2 is connected to the rotating hole through a bearing. The provided bearing can reduce the friction force of the first rotating shaft 2 during rotation, and improve the stability of the first rotating shaft 2 during rotation.

[0025] like Figure 3 , Figure 6 and Figure 7As shown, the universal transmission assembly 3 includes a claw-shaped member 301 fixedly connected to the end of the first rotating shaft 2, and a movable member 302 is movably connected inside the claw-shaped member 301. A plurality of ball grooves 303 are provided on the outer surface of the movable member 302 and the inner wall of the claw-shaped member 301, and a plurality of ball grooves 303 are provided inside each of the plurality of ball grooves 303. By utilizing the cooperation between the ball grooves 303 and the ball grooves 303, after the movable member 302 is tilted inside the claw-shaped member 301, the claw-shaped member 301 can still be moved by the cooperation between the ball grooves 304 and the ball grooves 303. (Since the ball member 304 is always located between the ball member 304 and the ball groove 303, and the ball member 304 can only roll between the ball member 304 and the ball groove 303 and cannot pass between the ball member 304 and the ball groove 303, the first rotating shaft 2 and the second rotating shaft 4 can transmit motion at the same instantaneous angular velocity at any angle, thereby ensuring the smoothness and constant speed of power transmission), control the rotation of the movable member 302; the movable member 302 is spherical in shape, and the second rotating shaft 4 is fixedly installed at the center of the bottom of the movable member 302.

[0026] like Figure 3 and Figure 4 As shown, the material spreading component 5 includes a turntable 501 fixedly installed at the bottom end of the second rotating shaft 4, and a plurality of fixed columns 502 are fixedly provided at one end of the turntable 501 away from the second rotating shaft 4. When the turntable 501 rotates half a circle, the plurality of fixed columns 502 can not only break up the agglomerated materials, but also bring the materials at the bottom of the slope to the top of the slope. When the turntable 501 rotates another half a circle, the materials are evenly spread downward from the top of the slope to avoid the problem of uneven thickness or large difference in compactness of the road edge due to material agglomeration or uneven thickness. At the same time, by tilting the turntable 501, a certain amount of material can be accommodated below the front side of the turntable 501.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the shaking component 6 includes a mounting plate 601 fixedly mounted on the trimming scraper 1, a movable groove 602 is provided on the mounting plate 601 at a position corresponding to the second rotating shaft 4, a protrusion 603 is fixedly provided inside the movable groove 602; the diameter of the movable groove 602 is larger than the diameter of the second rotating shaft 4; a plurality of matching grooves 401 are provided at a position corresponding to the protrusion 603 on the second rotating shaft 4, the end of the protrusion 603 away from the movable groove 602 is an arc surface, and the plurality of matching grooves 401 are all arc grooves. By setting the shaking component 6, when the second rotating shaft 4 rotates, the protrusion 603 and the plurality of matching grooves 401 can be used to rotate. The cooperation between the matching grooves 401 can make the second rotating shaft 4 and the material dispersing component 5 shake (when the protrusion 603 enters one of the matching grooves 401, the second rotating shaft 4 and the movable groove 602 are in a concentric state, and when the protrusion 603 disengages from the matching groove 401, the center points of the second rotating shaft 4 and the movable groove 602 are offset, so that the protrusion 603 continuously enters and disengages from the matching groove 401 to cause the second rotating shaft 4 and the material dispersing component 5 to shake), so as to utilize the shaking to allow the multiple fixed rods 502 to loosen the material when inserted into the material, ensuring that the turntable 501 can compact the slope evenly.

[0028] In summary, the effects are as follows: Good continuity of material handling: the continuous rotation of the turntable 501 and the handling of the material by the fixed column 502 during the rotation process enable the breaking up, transportation and paving of the material to be carried out continuously without frequent manual intervention or additional equipment assistance, which greatly improves the continuity of construction and effectively shortens the overall time of road edge construction.

[0029] Enhanced material mixing uniformity: During the process of the fixed column 502 breaking up the agglomerated materials and transporting the materials between the bottom and top of the slope, the materials at different positions are fully mixed. This helps to make the composition of the materials more uniform, avoids the problem of uneven quality of the road edge caused by the uneven original distribution of materials, and improves the overall stability and durability of the road edge.

[0030] Improve the uniformity of slope compaction: The shaking component 6 enables the fixed column 502 to loosen the material when inserted into the material, creating more favorable conditions for the compaction work of the rotating disk 501 and the finishing scraper 1. At the same time, the shaking of the fixed column 502 during the rotation process also helps to further evenly distribute the material, so that the rotating disk 501 and the finishing scraper 1 can compact the slope more evenly, reducing road diseases caused by uneven compaction, such as cracks, potholes, etc.

[0031] Coping with various material characteristics: Whether it is sticky materials that are easy to clump, or materials with large particles and poor fluidity, the device can effectively handle them through the action of the rotating disk 501 and the fixed column 502. During the rotation and shaking process, the fixed column 502 can automatically adjust the force on the material according to the actual situation of the material to ensure that the material is fully broken up and evenly spread.

[0032] The driving member 7 and the mobile device described in this application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0033] The working process is as follows: S1: Figure 1 and Figure 2 As shown, when in use, the trimming scraper 1 is fixedly mounted on a mobile device, and when the mobile device moves, the trimming scraper 1 and the material thinning assembly 5 trim the edge of the road base at the same time; S2: Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, by starting the driving member 7, the first rotating shaft 2 drives the second rotating shaft 4 to rotate through the universal transmission assembly 3, and then the second rotating shaft 4 drives the material dispersing assembly 5 to rotate; S3: Figure 2 As shown, when the turntable 501 rotates half a circle, the multiple fixed columns 502 can not only break up the agglomerated materials, but also bring the materials at the bottom of the slope to the top of the slope. When the turntable 501 rotates another half circle, the materials are evenly spread from the top of the slope downward, thereby avoiding the problem of uneven thickness or large difference in compactness at the edge of the road due to agglomeration or uneven thickness of the materials. S4: Figure 2 As shown, by tilting the turntable 501, a certain amount of material can be accommodated below the front side of the turntable 501; S5: Figure 2 , Figure 4 and Figure 5 As shown, by setting the shaking component 6, when the second rotating shaft 4 rotates, the second rotating shaft 4 and the material dispersing component 5 can be shaken by utilizing the cooperation between the protrusion 603 and the plurality of matching grooves 401, so that by utilizing the shaking, the plurality of fixing rods 502 can loosen the material when being inserted into the material, ensuring that the turntable 501 can compact the slope evenly; S6: Figure 1 and Figure 2 As shown, the slope is compacted for the second time by a trimming scraper 1 to keep the edge neat.

[0034] 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 and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
