Description

Technical Field

[0001] The present invention belongs to the technical field of concrete paving, and specifically relates to a concrete paving device for road construction. Background Art

[0002] Currently, during road concrete construction, concrete needs to be poured onto the road, and then a concrete paver is used to spread the concrete so that the concrete is evenly laid on the road.

[0003] When most existing concrete pavers work, they mostly rely on a driving mechanism (such as a towing vehicle) to drive a scraper to move along the road, and the scraper scrapes the concrete layer to achieve the concrete spreading operation. However, since the concrete poured on the road cannot ensure comprehensive coverage of the entire road, some positions on the road are prone to low-lying phenomena due to lack of concrete. When the scraper scrapes the concrete layer, the concrete layer moves forward along the road together with the scraper. Since the forward-moving concrete layer does not have the effect of moving along the width direction of the road, it cannot cover the low-lying positions on the road, resulting in unevenness of the spread concrete. Summary of the Invention

The shifting rod penetrates through the chute and is movably matched with the chute.

[0008] As a further improvement of the present invention: the vibration exciting assembly includes a support rod, a vibration exciting rod, a vibration exciting plate and a first elastic member.

The second driving assembly includes an inclined push plate, a connecting rod and an extension rod. There are several groups of inclined push plates. The several inclined push plates are fixedly arranged on the circumferential side wall of the turntable.

[0009] As a further improvement of the present invention: a second support plate is further fixedly arranged on the side of the first scraping plate away from the plurality of second scraping plates. A second guiding rod is fixedly arranged at the upper end of the support rod. The upper end of the second guiding rod penetrates through the second support plate and is movably matched with the second support plate.

Specific embodiments

[0014] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0015] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0016] Please refer to Figure 1 and Figure 2 , this embodiment provides a concrete paving device for road construction, including a first scraper 10, a second scraper 20, a first drive assembly 30, a vibration excitation assembly 40, and a second drive assembly 50. A bracket 101 is provided on the first scraper 10, and the bracket 101 is connected to an external towing vehicle (not shown in the figure). There are several groups of the second scrapers 20, and the several second scrapers 20 are arranged on one side of the first scraper 10 and are spaced apart along the length direction of the first scraper 10. The first drive assembly 30 is installed on the side wall of the first scraper 10, and the first drive assembly 30 is used to drive the several second scrapers 20 to reciprocate along the length direction of the first scraper 10. The vibration excitation assembly 40 is arranged on the side of the first scraper 10 away from the several second scrapers 20. The second drive assembly 50 is arranged on the side wall of the first scraper 10 and is used to drive the vibration excitation assembly 40 to vibrate so as to perform vibration excitation treatment on the paved concrete.

[0017] When it is necessary to pave road concrete, an external towing vehicle drives the first scraper 10 to move along the length of the road through the bracket 101. The first scraper 10 scrapes the concrete along the length direction of the road, thereby leveling the concrete and realizing the paving of the concrete on the road. While the first scraper 10 is moving, the second driving assembly 30 is used to drive a plurality of second scrapers 20 to reciprocate along the length direction of the first scraper 10 (that is, a plurality of second scrapers 20 reciprocate along the width direction of the road). At the same time, the second driving assembly 50 is used to drive the vibration assembly 40 to vibrate. When the plurality of second scrapers 20 reciprocate, the concrete on one side of the first scraper 10 is scraped along the width direction of the road, so that the concrete can automatically fill the possible pothole positions on the road, thereby ensuring the flatness of the paved concrete. When the vibration assembly 40 vibrates, the paved concrete can be vibrated to vibrate out the air in the concrete, thereby ensuring the compactness of the concrete and improving the paving effect of the road concrete.

[0018] Please refer to Figure 1 and Figure 3 , in one embodiment, a first guide rod 102 is fixedly arranged on the side wall of the first scraper 10. A plurality of the second scrapers 20 are movably sleeved outside the first guide rod 102. A fixing plate 201 is fixedly arranged on the tops of the plurality of second scrapers 20. A first support plate 103 is fixedly arranged on the side wall of the first scraper 10. The first driving assembly 30 includes a motor 301, a turntable 302, a driving rod 303 and a dial rod 305. The motor 301 is fixedly arranged on the upper part of the first support plate 103. The turntable 302 is installed at the output end of the motor 301. One end of the driving rod 303 is fixedly connected to the fixing plate 201, and the other end extends above the turntable 302 from the upper part of the first scraper 10. A chute 304 is formed in the driving rod 303. The dial rod 305 is fixedly arranged at an eccentric position on the side of the turntable 302 away from the motor 301. The dial rod 305 penetrates through the chute 304 and is movably matched with the chute 304.

[0019] When an external vehicle pulls the vehicle and drives the first scraper 10 to move along the length direction of the road through the bracket 101, the first scraper 10 scrapes the concrete laterally. At the same time, the motor 301 drives the turntable 302 to rotate, and then drives the lever 305 to move in a circular motion. When the lever 305 moves in a circular motion, through the movable cooperation with the chute 304, it drives the driving rod 303 to reciprocate along the length direction of the first scraper 10. The driving rod 303 drives a plurality of second scrapers 20 to synchronously reciprocate along the length direction of the first scraper 10 through the fixing plate 201, and then scrapes the concrete gathered on one side of the first scraper 10 in the width direction of the road, so that the concrete can automatically fill the possible pothole positions on the road, thereby improving the flatness after concrete paving; when the plurality of second scrapers 20 reciprocate along the length direction of the first scraper 10, through the movable cooperation between the plurality of second scrapers 20 and the first guide rod 102, the smoothness of the movement of the plurality of second scrapers 20 can be ensured, and then the scraping effect of the concrete on one side of the first scraper 10 is improved.

[0020] Please refer to Figure 2 、 Figure 3 and Figure 4 , in one embodiment, the vibration exciting assembly 40 includes a support rod 401, a vibration exciting rod 402, a vibration exciting plate 403 and a first elastic member 405. The vibration exciting plate 403 is arranged at the lower part of the side of the first scraper 10 away from the plurality of second scrapers 20. The support rod 401 is arranged above the vibration exciting plate 403. There are several groups of the vibration exciting rods 402. The several vibration exciting rods 402 are fixedly arranged at the bottom of the support rod 401 and are spaced along the length direction of the support rod 401. The first elastic member 405 is arranged at the upper part of the support rod 401 and is used to provide elastic support for the support rod 401, so that the lower ends of the several vibration exciting rods 402 are in contact with the upper surface of the vibration exciting plate 403. The second driving assembly 50 includes an inclined push plate 501, a connecting rod 502 and an extension rod 503. There are several groups of the inclined push plates 501. The several inclined push plates 501 are fixedly arranged on the circumferential side wall of the turntable 302. The several inclined push plates 501 are annularly spaced on the circumferential side wall of the turntable 302. The connecting rod 502 is fixedly arranged at the upper end of the support rod 401. One end of the extension rod 503 is fixedly connected to the side wall of the connecting rod 502, and the other end extends between two adjacent groups of the inclined push plates 501.

[0021] When an external towing vehicle drives the first scraper 10 through the bracket 101, the first scraper 10 can drive the vibration excitation plate 403, the support rod 401 and several vibration excitation rods 402 to move synchronously. The vibration excitation plate 403 is dragged along the surface of the paved concrete. When the motor 301 drives the turntable 302 to rotate and then drives several second scrapers 20 to reciprocate along the length direction of the first scraper 10, the turntable 302 can also drive several inclined push plates 501 to rotate. When the upper surface of a certain group of inclined push plates 501 acts on the extension rod 503, it can push the extension rod 503 to move upward, and then drive the support rod 401 and several vibration excitation rods 402 to move upward through the connecting rod 502. At this time, the first elastic member 405 is compressed by force, and the lower ends of several vibration excitation rods 402 are far away from the vibration excitation plate 403. As the group of inclined push plates 501 continues to rotate, when the extension rod 503 slides off the upper end of the group of inclined push plates 501, the first elastic member 405 pushes the support rod 401 and then drives the support rod 401 to move downward. The support rod 401 drives the connecting rod 502, the extension rod 503 and several vibration excitation rods 402 to move downward. The lower ends of several vibration excitation rods 402 impact the upper surface of the vibration excitation plate 403, and the vibration excitation plate 403 transmits the impact force to the concrete below, thereby vibrating and compacting the paved concrete and at the same time vibrating out the air in the concrete; by driving several inclined push plates 501 to rotate through the turntable 302, the upper surfaces of several inclined push plates 501 act on the extension rod 503 in sequence, and in cooperation with the first elastic member 405, continuous up and down movement of several vibration excitation rods 402 can be realized, and then continuous impact on the vibration excitation plate 403 can be carried out to realize continuous vibration compaction of the road concrete.

[0022] Please refer to Figure 4 , in an embodiment, a second support plate 104 is further fixedly arranged on a side of the first scraper 10 away from several second scrapers 20. A second guide rod 404 is fixedly arranged at the upper end of the support rod 401. The upper end of the second guide rod 404 penetrates through the second support plate 104 and is movably matched with the second support plate 104. One end of the first elastic member 405 is connected to the second support plate 104, and the other end is connected to the support rod 401.

[0023] Through the movable matching effect of the second guide rod 404 and the second support plate 104, a guiding effect can be provided for the up and down movement of the support rod 401 and several vibration excitation rods 402, so as to ensure that several vibration excitation rods 402 can move up and down smoothly, and then smoothly carry out vibration excitation treatment on the vibration excitation plate 403.

[0024] Please refer to Figure 5, in one embodiment, a third support plate 105 is further fixedly arranged on one side of the first scraping plate 10 away from the plurality of second scraping plates 20. A third guide rod 407 is fixedly arranged on the upper surface of the vibration excitation plate 403. A guide sleeve 408 is movably sleeved on the upper end of the third guide rod 407. The guide sleeve 408 is fixedly arranged at the bottom of the third support plate 405. The vibration excitation plate 403 is further connected to the guide sleeve 408 through a second elastic member 406. The second elastic member 406 is used to provide an elastic pulling force to the vibration excitation plate 403.

[0025] When the plurality of vibration excitation rods 402 move downward and impact the upper surface of the vibration excitation plate 403, the vibration excitation plate 403 is impacted and thus moves downward. The vibration excitation plate 403 drives the third guide rod 407 to move downward relative to the guide sleeve 408. When the plurality of vibration excitation rods 402 move upward, the second elastic member 406 can pull the vibration excitation plate 403 and thus drive the vibration excitation plate 403 and the third guide rod 407 to move upward, realizing the reset of the vibration excitation plate 403.

[0026] In one embodiment, the first elastic member 405 and the second elastic member 406 can be springs or metal shrapnel, and there is no limitation here.

[0027] In the embodiment of the present invention, when it is necessary to pave road concrete, an external towing vehicle drives the first scraping plate 10 to move along the length of the road through the bracket 101. The first scraping plate 10 scrapes the concrete along the length direction of the road, thereby leveling the concrete and realizing the paving of the concrete on the road. While the first scraping plate 10 is moving, the second driving assembly 30 is used to drive the plurality of second scraping plates 20 to reciprocate along the length direction of the first scraping plate 10. At the same time, the second driving assembly 50 is used to drive the vibration excitation assembly 40 to vibrate. When the plurality of second scraping plates 20 reciprocate, the concrete on one side of the first scraping plate 10 is scraped along the width direction of the road, so that the concrete can automatically fill the possible pothole positions on the road, thereby ensuring the flatness of the paved concrete. When the vibration excitation assembly 40 vibrates, the paved concrete can be vibration-excited to vibrate out the air in the concrete, thereby ensuring the compactness of the concrete and improving the paving effect of the road concrete. Compared with the prior art, during the paving process of the road concrete, the concrete can be automatically filled into the pothole positions of the road, thereby ensuring the flatness of the paved concrete and improving the paving effect of the concrete. And after the concrete paving is completed, the concrete can be timely vibration-excited to eliminate the air inside the concrete, avoiding the phenomenon of air pockets inside the concrete after coagulation, and improving the paving strength of the concrete.

[0028] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
