TECHNICAL FIELD
[0001] The utility model belongs to road construction technical field, concretely relates to a construction road surface scraping device. BACKGROUND
[0002] Road surface flatness is an important standard for evaluating road quality, directly affecting the comfort and safety of driving. Driving on a flat road surface can reduce bumps and vibrations, improving passenger experience; on the contrary, a bumpy road surface will increase the bumpiness of the vehicle, causing passengers to be uncomfortable, and may damage vehicle parts, increasing maintenance costs and accident risks. Especially in high-speed or emergency situations, uneven road surfaces are more likely to cause vehicle loss of control, so maintaining good road surface flatness is crucial to ensuring traffic safety and improving driving comfort. By improving road construction technology and maintenance strategies, this situation can be effectively improved to promote efficient operation of the transportation system.
[0003] During road construction, the scraping of the construction road surface is a key operation, and its main purpose is to use a special scraping device to level the road surface to ensure that the road surface meets the design requirements for flatness. When scraping the construction road surface, it is often necessary to scrape it in both directions to ensure the flatness and construction quality of the road surface. For example, in some projects with high requirements for road surface flatness, such as highways, airport runways, etc., simply relying on one-way scraping cannot completely eliminate the slight unevenness of the road surface, and it is necessary to scrape it in both directions to meet the design requirements. In addition, in different conditions of concrete setting, it is also necessary to scrape it in both directions to ensure the flatness of the road surface. However, most existing road surface scraping devices have scraping plates that can only be tilted in one direction, which makes it difficult to operate in the opposite direction. This one-way scraping limitation brings many inconveniences and problems in actual construction, not only affecting construction efficiency, but also possibly leading to substandard road surface flatness, thereby affecting the quality and service life of the entire project.

Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more of the features.
[0024] Embodiment one:
[0025] Please refer to Figures 1-4 As shown in the figure, a construction pavement scraping device, comprising:
[0026] The driving part 2 and the guide rail 1 are symmetrically arranged on both sides of the road, the driving part 2 slides on the guide rail 1, the top surface of the driving part 2 is fixedly provided with a lifting assembly, the top ends of the two lifting assemblies are fixedly provided with a support frame 4, the bottom surface of the support frame 4 is fixedly provided with a boom 5 on both sides, and a scraping mechanism is arranged between the two booms 5.
[0027] The scraping mechanism comprises a scraping plate 10, the scraping plate 10 is arranged in a fan shape, the two ends of the scraping plate 10 are fixedly provided with a pressing plate 11, the two sides of the scraping plate 10 are symmetrically provided with a right-angle frame 9, the tail ends of the two right-angle frames 9 are fixedly provided at the connection between the scraping plate 10 and the pressing plate 11, the right-angle ends of the two right-angle frames 9 are fixedly provided with a transmission shaft 8, the transmission shaft 8 penetrates through the two booms 5 and is rotatably connected with the booms 5, the center of the transmission shaft 8 is provided with a transmission assembly, and the connection between the transmission shaft 8 and the two booms 5 is provided with a limiting assembly.
[0028] By Figure 3It can be known that the limiting assembly includes two symmetrically arranged limiting plates 6, the side walls of the two limiting plates 6 opposite to each other are fixedly arranged on the side walls of the two hangers 5 opposite to each other, the two limiting plates 6 are L-shaped, and a positioning plate 7 is arranged between the inner included angles of the two limiting plates 6.
[0029] As can be known from the above, when the road surface needs to be scraped and flattened, the whole device is first installed on the guide rail 1 on both sides of the road through the driving part 2. The driving part 2 includes but is not limited to mechanical structures that can provide power for the device and drive it to slide on the slide rail, such as motors, hydraulic cylinders, air cylinders and the like. These structures all belong to the prior art, and thus will not be described in detail. The guide rail 1 facilitates the device to be in a horizontal position during operation. When the driving part 2 slides on the guide rail 1, the scraping plate 10 and the pressing plate 11 are first lifted by the lifting assembly. The first pass is forward flattening, so the scraping plate 10 and the pressing plate 11 are then lowered to the height required for scraping by the lifting assembly. The arc-shaped scraping plate 10 can better adapt to the profile of the road surface, especially when the road surface has a certain degree of undulation or unevenness. The arc-shaped design can ensure that the scraping plate 10 maintains good contact with the road surface, thereby improving the scraping effect. The pressing plate 11 is fixed at both ends of the arc-shaped scraping plate 10 and can apply additional pressure to the road surface during scraping to ensure that the scraping plate 10 is in close contact with the road surface, thereby enhancing the scraping effect. After one pass of forward scraping, the transmission shaft 8 is driven to rotate by the transmission assembly. Since the positioning plate 7 is arranged between the inner included angles of the limiting plates 6, the limiting plates 6 are L-shaped, the inner included angle thereof is 90°, and the positioning plate 7 is fixedly arranged on the transmission shaft 8, the transmission shaft 8 can only rotate within the 90° included angle of the limiting plates 6. Therefore, when the transmission assembly drives the transmission shaft 8 to rotate by 90°, the rotation is stopped under the action of the limiting plates 6. The scraping plate 10 and the pressing plate 11 are fixedly arranged at both ends of the transmission shaft 8 by the two right-angle frames 9. Therefore, when the transmission shaft 8 rotates by 90°, the scraping plate 10 and the pressing plate 11 are correspondingly turned over by 90°, similar to mirror image turning over. At this time, the whole device is moved in the reverse direction on the track by the driving part 2, and the reverse scraping of the road surface is completed.
[0030] Specifically, with regard to the above, as shown in Figure 1 and Figure 2 The transmission assembly includes two chain wheels 12 arranged one above the other, and the outer walls of the two chain wheels 12 are jointly meshed with a chain 13. The chain wheel 12 located at the upper side is fixedly sleeved at the center of the outer wall of the transmission shaft 8, the chain wheel 12 located at the lower side is fixedly provided with a driving shaft 15 at the center, and the end surface of the driving shaft 15 is fixedly provided with a first motor 14.
[0031] Both ends of the driving shaft 15 are rotatably provided with fixed plates 16, the bottom surfaces of the two fixed plates 16 are fixedly provided with a bearing plate 17, both ends of the bearing plate 17 are fixedly provided on the two hangers 5, and the mounting plate of the first motor 14 is fixedly provided on the top surface of the bearing plate 17.
[0032] As can be seen from the above, the first motor 14 is a forward and reverse servo motor, which belongs to the prior art, and thus will not be described again. When the first motor 14 is started, it drives the driving shaft 15 to rotate, drives the sprocket 12 fixedly connected thereto to rotate, and through the meshing relationship between the chain 13 and the two sprockets 12, the three form a transmission. The sprocket 12 on the upper side is fixedly provided on the outer wall of the transmission shaft 8, so as to drive the transmission shaft 8 to rotate synchronously, thereby changing the direction of the scraping plate 10.
[0033] Specifically, with reference to the above, as shown in Figure 1 The lifting assembly includes a telescopic cylinder 3 fixedly provided on the top surface of the driving part 2, and the top end of the movable shaft of the telescopic cylinder 3 is fixedly provided on the bottom end of the support frame 4.
[0034] As can be seen from the above, when the road surface needs to be scraped in the forward and reverse directions, the telescopic cylinder 3 can lift the scraping plate 10 to a certain height, so that it can be smoothly turned over. After turning over, the telescopic cylinder 3 adjusts the height of the scraping plate 10 again, so that it is in contact with the road surface and performs reverse scraping operation.
[0035] Example two:
[0036] With reference to the above, as shown in Figures 1-3 The bottom end of each of the two hangers 5 is fixedly provided with a plurality of springs 23, the ends of the plurality of springs 23 away from the hangers 5 are fixedly provided with a vibrating plate 22, and a vibrating assembly is provided above the vibrating plate 22.
[0037] The vibrating assembly includes two side plates 18 fixedly provided on the bottom surface of the bearing plate 17 and a second motor 19, the lower end of each of the two side plates 18 is rotatably provided with a connecting shaft 20, the opposite ends of the two connecting shafts 20 are fixedly provided with an eccentric wheel 21 in the shape of a long strip, the outer wall of the eccentric wheel 21 is tangent to the top surface of the vibrating plate 22, and the output shaft of the second motor 19 is fixedly provided on the end surface of one of the connecting shafts 20.
[0038] From the above, the second motor 19 is a positive and negative rotation servo motor, belongs to the prior art, therefore no longer tedious, through the second motor 19 and the connecting shaft 20, drive eccentric wheel 21 rotation, because eccentric wheel 21's outer wall and the vibration flat plate 22 tangent, vibration flat plate 22 through a plurality of springs 23 fixedly arranged at the bottom end of the boom 5, through the rotation of eccentric wheel 21, make vibration flat plate 22 constantly produce vibration, through vibration flat plate 22 to the reciprocating strike of the scraping plate 10 and the pressing plate 11, so can help the device in scraping operation, especially the scraping of the concrete pavement, can further eliminate these surface defects, vibration can make the concrete surface particles rearrange, fill the scratch and uneven place, thereby improving the flatness and smoothness of the pavement.
[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
