Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road construction equipment, in particular to a road tamping equipment for urban roads. BACKGROUND

[0002] In some engineering construction, such as the filling of roadbed, dam and the backfilling of construction site, etc. The soil is often used as building material. Due to excavation, transportation and filling, the original structure and state of the soil are changed. If not compacted by artificial, the void ratio is often large, and the compressibility is high and the shear strength is low, which is difficult to meet the needs of engineering. In order to reduce the post-construction settlement of the filling and improve the strength, the soil must be compacted by rolling, tamping or vibration according to certain standards in engineering. The existing road tamping equipment for urban roads, when the equipment tamps the road surface, the ground soil is dry, and when the tamping wheel is rolled and tamped, the ground is easy to crack, resulting in poor tamping. When it rains, the ground is easy to collapse. When the tamping wheel tamps and rolls the ground, there is clay sticking to the surface of the tamping wheel. However, the equipment cannot effectively clean the clay when it is working, so the clay on the surface of the tamping wheel increases, which affects the tamping of the ground. When the scraper cleans the clay on the surface of the tamping wheel, the stones on the ground may be imprinted on the surface of the tamping wheel due to the gravity of the tamping wheel. When the scraper contacts the tamping wheel, the scraper may be damaged because it is fixed. The lower end of the one-piece cast tamping block is flat, which may cause the soil around the contact between the lower end of the one-piece cast tamping block and the ground to be uplifted when the one-piece cast tamping block tamps the ground. When the tamping wheel encounters a protruding ground, the tamping block will cause the entire equipment to be uplifted, so that the tamping wheel leaves the ground. The tamping block is driven by a motor, and when the downward force is less than the upward force, the rotating shaft may be bent. The existing technology for adjusting the tamping depth is still controlled by hydraulic pressure and PLC, but the accuracy of the hydraulic pressure cannot be guaranteed, so the accuracy of the tamping depth is low when the hydraulic pressure and PLC are used to adjust the tamping depth. SUMMARY

[0003] In view of the defects of the prior art, the present application provides a road tamping equipment for urban roads, which solves the problems of poor tamping, collapse of the ground in rainy weather, clay adhesion during tamping and rolling of the tamping wheel, and the inability to effectively clean the tamping wheel during operation, thereby causing more and more clay to adhere to the surface of the tamping wheel and affecting the tamping of the ground. In addition, the weight of the tamping wheel itself may imprint stones on the surface of the tamping wheel, which may damage the scraper when the scraper contacts the tamping wheel. Furthermore, when the integrated cast tamping block tamps the ground, it is easy to cause the surrounding soil around the lower end of the integrated cast tamping block to be uplifted, and the integrated cast tamping block to be uplifted when encountering a protruding ground.

[0013] Compared with the prior art, the road tamping device for urban roads has the following beneficial effects:

[0014] 1. A water nozzle is installed on the left side of the frame body of the left side of the frame body of the tamping device frame body, which sprays water on the ground during operation of the device. The amount of water sprayed is not large, and the water is sprayed in a misty manner, which makes the ground more humid. This method not only increases the adhesion of the soil, but also strengthens the strength of the soil. When the tamping wheel compacts the ground, compared with the ground without water spraying, this method is better than the ground without water spraying in terms of soil tamping strength and soil adhesion. In the existing technology, there is no water spraying on the ground during tamping. Through this method, the problem of cracks on the ground caused by the tamping wheel when the tamping wheel is rolling and tamping is solved, which causes the tamping to be not solid, and the ground collapses when it rains.

[0015] 2. When the tamping wheel tamps the ground, some soil is adhered to the surface of the tamping wheel. However, in the existing technology, when the surface of the tamping wheel is adhered with soil, the device can only be stopped to scrape off the clay on the surface. In this technology, an inclined through hole is provided on the right side of the frame body of the left side of the frame body of the tamping device frame body. The inclined through hole is convenient for scraping off the clay for cleaning. An installation plate is installed on the inner surface of the inclined through hole, and a chamfered scraper is installed on one end of the installation plate, thereby completing the scraping of the clay on the surface of the tamping wheel. Since the inclination angle of the installation plate is consistent with the inclination angle of the inclined through hole, the scraped clay will flow out of the device along the inclined angle and fall onto the ground, solving the problem of clay adhesion when the tamping wheel is rolling and tamping the ground, and the problem of ineffective cleaning during device operation, which causes the clay on the surface of the tamping wheel to increase, thereby affecting the tamping of the ground.

[0016] 3. A third groove is provided on one end of the installation plate, and a plurality of pressure relief springs are installed on the inner surface of the third groove. The pressure relief springs are fixed on the inner surface of the second groove. First, considering that the tamping wheel will adhere to relatively solid stones on the surface due to the weight of the tamping wheel when tamping the ground, this problem exists in reality. When the stones come into contact with the chamfered scraper, the chamfered scraper moves downward to the third groove under the action of the pressure relief spring, thereby preventing the chamfered scraper from hard contact with the stones, thereby solving the problem of damage to the scraper caused by the stones on the surface of the tamping wheel when the scraper cleans the clay on the surface of the tamping wheel due to the gravity of the tamping wheel.

[0017] 4. When the one-piece cast tamping block tamps the ground, as shown in Figure 16As shown, a represents the ground, b represents the raised soil, c represents the integrated cast compaction block in the technology, and the difference between the lower end of the integrated cast compaction block and the lower end of the integrated cast compaction block without the arc is that the ground does not have obvious raised soil, but the integrated cast compaction block without the arc has more raised soil when the ground is compacted, so the technology solves the problem that the lower end of the integrated cast compaction block is relatively flat, and the integrated cast compaction block is easy to cause the phenomenon of raised soil around the lower end of the integrated cast compaction block when the integrated cast compaction block is compacted on the ground. Figure 16 As shown, a represents the ground, b represents the raised soil, c represents the integrated cast compaction block in the technology, and the difference between the lower end of the integrated cast compaction block and the lower end of the integrated cast compaction block without the arc is that the ground does not have obvious raised soil, but the integrated cast compaction block without the arc has more raised soil when the ground is compacted, so the technology solves the problem that the lower end of the integrated cast compaction block is relatively flat, and the integrated cast compaction block is easy to cause the phenomenon of raised soil around the lower end of the integrated cast compaction block when the integrated cast compaction block is compacted on the ground.

[0018] 5、In the existing technology, when the compaction block encounters unevenly upwardly protruding ground, the compaction block will cause the entire device to be raised upward, so that the compaction wheel is separated from the ground, and because the compaction block is driven by a motor, when the downward force is less than the upward force, the rotating shaft may be bent, because the rotating shaft drives the connecting block to move, and the connecting block drives the compaction block to compact the ground, so in the technology, when the compaction block encounters upwardly protruding ground, the phenomenon of upward tilting of the device is solved due to the action of the high-strength extension spring and the weight of the two groups of compaction wheels being much greater than the weight of the integrated cast compaction block, and the problem of bending of the rotating shaft when the downward force is less than the upward force is also solved.

[0019] 6、In the existing technology, the size of the compaction depth is still determined by hydraulic pressure and PLC control, but in actual operation, the size of the hydraulic pressure cannot guarantee accurate adjustment, so the accuracy of the compaction depth adjustment on the ground by hydraulic pressure and PLC control is low, and in the technology, the compaction depth is adjusted by changing the connecting body, the connecting body has multiple groups of self-made specifications with different lengths, and the connecting body is processed according to strict size specifications, so the accuracy of the compaction depth on the ground can be effectively guaranteed.

When in use, the device is moved to the ground to be rammed by the universal movable wheel 7, the first drive motor 2 is started to drive the rotating shaft 3 to rotate and drive the transmission gear 4 to rotate, the movable rod 5 is moved upward through the gear transmission principle of the transmission gear 4 and the driving gear block 6, so that the ramming wheel 29 contacts the ground, then the motor drives the rotating body 17 to rotate, the rotating wheel 16 is driven to rotate through the transmission belt 20, and the ramming wheel 29 is driven to rotate, so that the ground is rammed. The second drive motor 10 is started to drive the rotating shaft 12 to rotate, so that the connecting body 36 rotates and drives the connecting block 43 to rotate. Since the connecting block 43 is connected with the movable runner 41, when the connecting body 36 rotates, the connecting block 43 drives the movable runner 41 to rotate. Since the connecting body 36 is a cam structure, the movable runner 41 can move up and down, the driving carrier 38 is driven to move up and down by the movable runner 41, and the integrated cast ramming block 33 is driven to move up and down, so that the integrated cast ramming block 33 performs the ramming operation on the ground. As shown in Figure 16 , a represents the ground, b represents the raised soil, and c represents the integrated cast ramming block 33 in this technology. As shown in Figure 16It can be obviously contrasted that the lower end of the integral cast ramming block 33 is provided with a rounded arc, and there is a difference between the rounded arc and the integral cast ramming block 33 without the rounded arc. When the rounded arc is provided, the ground does not appear obvious uplifted soil blocks, but the integral cast ramming block 33 without the rounded arc appears more uplifted soil blocks when the ground is rammed. Therefore, the present technology solves the problem that the lower end of the integral cast ramming block 33 is relatively flat, and when the integral cast ramming block 33 is used to ram the ground, the phenomenon of uplifted soil blocks around the contact between the lower end of the integral cast ramming block 33 and the ground is easily caused. When the integral cast ramming block 33 moves up and down, the two sides of the integral cast ramming block 33 are penetrated by the fixed cylinders 32, and the outer surfaces of the fixed cylinders 32 are provided with high-strength extension springs 34. When the integral cast ramming block 33 encounters an unevenly upwardly protruding ground, the integral cast ramming block 33 will cause the entire device to be uplifted upward, so that the ramming wheels 29 are separated from the ground. Moreover, because the integral cast ramming block 33 is driven by a motor, when the downward force is less than the upward force, the rotating shaft 12 may be bent. Because the rotating shaft 12 drives the connecting block 43 to move, and the connecting block 43 drives the integral cast ramming block 33 to ram the ground, in the present technology, when the integral cast ramming block 33 encounters an upwardly protruding ground, the high-strength extension springs 34 are used, and the weight of the two groups of ramming wheels 29 is far greater than the weight of the integral cast ramming block 33, thereby solving the problem that the device is uplifted upward when the integral cast ramming block 33 encounters a protruding ground, and preventing the problem that the rotating shaft 12 may be bent when the downward force is less than the upward force. Moreover, when the ramming wheels 29 ram the ground, some soil is adhered to the surfaces of the ramming wheels. However, in the existing technology, when the soil is adhered to the surfaces of the ramming wheels 29, the device can only be stopped to scrape the adhered soil. In the present technology, the inclined through hole 21 is formed in the right side of the frame body on the left side of the ramming device frame body, the inclined through hole 21 is convenient for scraping and cleaning the adhered soil, the mounting plate 22 is installed on the inner surface of the inclined through hole 21, the chamfered scraper 23 is installed on one end of the mounting plate 22, thereby completing the scraping of the adhered soil on the surfaces of the ramming wheels 29. Because the inclination angle of the mounting plate 22 is consistent with the inclination angle of the inclined through hole 21, the scraped soil will flow out of the device along the inclined angle and fall to the ground, thereby solving the problem that the adhered soil cannot be effectively cleaned when the ramming wheels 29 ram and roll the ground, and the adhered soil on the surfaces of the ramming wheels 29 becomes more and more, thereby affecting the ramming of the ground. Moreover, the third recess 46 is formed in one end of the mounting plate 22, and a plurality of pressure relief springs 47 are installed on the inner surface of the third recess 46. The pressure relief springs 47 are fixed on the inner surface of the second recess 45. First, because the weight of the ramming wheels 29 affects the ramming of the ground,The surface of the tamper wheel 29 will stick to the relatively solid stones, and in reality, this problem also exists. When the stones contact the chamfered scraper 23, the chamfered scraper 23 moves downward to the lower part of the third groove 46 through the action of the decompression spring 47, thereby preventing the chamfered scraper 23 from hard contact with the stones, thereby solving the problem that when the scraper cleans the surface of the tamper wheel 29, the stones on the ground may be printed on the surface of the tamper wheel 29 due to the gravity of the tamper wheel 29 itself, and when the chamfered scraper 23 contacts the tamper wheel 29, the chamfered scraper 23 may be damaged due to the relatively fixed chamfered scraper 23. When the entire device is working, a water spraying nozzle 28 is installed on the left side of the frame body on the left side of the tamper device frame body 1. When the device is working, the ground is sprayed with water, and the amount of water sprayed will not be large, and the water is sprayed in a misty manner, so that the ground is relatively wet. This way not only increases the cohesiveness of the soil, but also strengthens the strength of the soil. When the tamper wheel 29 compacts and tamps the ground, compared with the ground without water spraying, this way is better than the ground without water spraying in terms of soil compaction strength and soil cohesiveness. Because there is no water spraying on the ground during the tamping process in the existing technology, this way solves the problem that when the device tamps the road surface, the soil on the ground is dry, and when the tamper wheel 29 is rolled and tamped, the ground is prone to cracking, thereby causing the tamping to be not solid. When it rains, the ground is prone to collapse. After the device is started, the water spraying nozzle 28 sprays water on the ground, which can increase the cohesiveness of the soil and the strength of the tamping when the tamper wheel 29 is rolled and tamped. The tamper wheel 29 is two groups, and the tamper wheel 29 is responsible for rolling and flattening the ground. The left tamper wheel 29 is used to preliminarily roll the ground, and then the integrated cast tamper block 33 is used to tamp the ground. After tamping, the right tamper wheel 29 is used for final rolling and tamping, and the work is completed. After the work is completed, the first driving motor 2 starts to drive the rotating shaft 3 to rotate, drives the transmission gear 4 to rotate, and drives the gear block 6 to move downward through the cooperation of the transmission gear 4 and the transmission gear 4. The movable rod 5 moves downward, so that the universal movable wheel 7 contacts the ground, and then the device is moved.
