Description

Technical Field

[0001] The present invention belongs to the technical field of road maintenance and construction equipment, and in particular relates to intelligent equipment for reinforcing highway subgrade and pavement and a control method thereof. Background Art

[0002] Pavement reinforcement refers to the measures taken to restore or improve the performance of the road surface, which decreases in surface performance and bearing capacity with age. When the structural condition or surface function of the road surface cannot meet the requirements of use, a reinforcement layer is added to the old road surface. With the rapid increase in traffic volume and axle load, the road is prone to varying degrees of damage in some locations after being run over by vehicles for a long time. Therefore, it is necessary to immediately reinforce and repair the cracked road surface to ensure road safety. When adding the reinforcement layer, mortar is generally injected into the inside of the crack through a pipe for filling. After the mortar overflows the road surface, a scraper is used to scrape the mortar on the top of the crack flat. At present, traditional pavement repair work often relies on manual operation, which has limited efficiency and may be inaccurate. Since the working environment of pavement repair is usually complex and changeable, including different types of road surfaces, traffic conditions and weather conditions, it is difficult for manual labor to carry out repair work in such a complex environment and faces challenges. The control ability of grouting equipment is not ideal, and the amount of slurry flowing out of the grouting equipment is difficult to effectively control, resulting in excessive outflow of slurry, which is prone to slurry accumulation and stratification, thus affecting the repair effect.

[0024] In the present invention, Figure 1 and Figure 2 The grouting assembly 5 includes a grouting support frame 500 vertically arranged on the front end of the movable frame 1 and a vertical grouting pipe 501 movably arranged on the grouting support frame 500, and a buffer slurry storage shell 5010 is provided at the top of the vertical grouting pipe 501, and the discharge port at the bottom end of the slurry collection box 4 is connected with the vertical grouting pipe 501 through a hose 22 and a buffer slurry storage shell 5010, and a grouting nozzle 5011 is detachably connected to the lower end of the vertical grouting pipe 501; an upper fixed support plate 502, a sliding support plate 503 and a lower fixed support plate 504 are provided on the outer side wall of the grouting support frame 500 from top to bottom, and a pair of sliding guide columns 505 are respectively provided between the two ends of the upper fixed support plate 502 and the two ends of the lower fixed support plate 504, and the two ends of the sliding support plate 503 are respectively slidably provided between the two ends of the upper fixed support plate 502 and the two ends of the lower fixed support plate 504. On the guide column 505, the buffer slurry storage shell 5010 is arranged on the sliding support plate 503, and the upper end of the vertical grouting pipe 501 is upwardly penetrated from the bottom of the sliding support plate 503 and connected to the top of the buffer slurry storage shell 5010, and the lower end of the vertical grouting pipe 501 downwardly passes through the lower fixed support plate 504, and a lifting cylinder 506 is fixed in the vertical direction at both ends near the upper fixed support plate 502. The two ends of the sliding support plate 503 are respectively connected to the output shaft of the lifting cylinder 506 arranged at both ends of the upper fixed support plate 502; during the grouting operation, before the grouting nozzle 5011 injects slurry into the grouting port 100, the sliding support plate 503 is first pushed to move on the sliding guide column 505 by the lifting cylinder 506, so that the grouting nozzle 5011 extends into the grouting port 100, so that the opening position of the grouting nozzle 5011 and the grouting port 100 is maintained at a suitable distance.

[0025] In the present invention, Figure 2 and Figure 3 As shown, a sliding limit groove 5012 is provided on the surface of the sliding support plate 503 along the length direction, a sliding support platform 5013 is provided in the sliding limit groove 5012, a pair of support guide rails 5014 are provided in the sliding limit groove 5012 for supporting the sliding support platform 5013 to slide in the length direction of the sliding limit groove 5012, a sliding limit passage opening 5015 parallel to the sliding limit groove 5012 is provided on the lower fixed support plate 504, and the lower end of the vertical grouting pipe 501 is extended from the sliding limit of the lower fixed support plate 504. The channel opening 5015 extends downward and passes through the lower fixed support plate 504; a horizontal driving cylinder 5015 is provided on the sliding support plate 503 outside the edge of one end of the sliding limit groove 5012, and the output shaft of the horizontal driving cylinder 5015 is connected to the end of the sliding support platform 5013. The horizontal driving cylinder 5015 pushes the sliding support platform 5013 to move back and forth in the sliding limit groove 5012 and drives the buffer slurry storage shell 5010 and the vertical grouting pipe 501 to move back and forth together. During this process, the vertical grouting pipe 501 injects slurry into the grouting port 100.

[0026] In the present invention, Figure 3 and Figure 4 As shown, a buffer support 5010 is provided at the bottom of the buffer slurry storage shell 5010, and the bottom of the buffer slurry storage shell 5010 is provided on the supporting sliding support platform 5013 through the buffer support 5010. The buffer support 5010 is a spring or an annular buffer rubber pad (such as a tire). During the process of the slurry collection box 4 conveying the slurry to the buffer slurry storage shell 5010, due to the large impact pressure of the slurry and the pouring pressure of the slurry is buffered in the buffer slurry storage shell 5010, the buffer slurry storage shell 5010 can start the buffering effect under the support of the buffer support 5010, and the buffer slurry storage shell 5010 can also achieve micro-oscillation buffering through inertia during the back-and-forth movement with the sliding support platform 5013, so that the slurry inside the buffer slurry storage shell 5010 is shaken as a whole, and the slurry density is more uniform.

[0027] like Figure 3 and Figure 4As shown, a threaded connection portion 501a is provided at the lower end of the vertical grouting pipe 501, and the lower end of the threaded connection portion 501a is threadedly connected to the inner wall of the top connection portion of the grouting nozzle 5011, and a fixed support ring 501b is provided on the outer wall of the vertical grouting pipe 501 above the threaded connection portion 501a. A distance sensor 501e electrically connected to the control box 10 is provided on the outer wall of the fixed support ring 501b; the lifting cylinder 506 pushes the sliding support plate 503 to move on the sliding guide column 505, driving the buffer slurry storage shell 5010 and the sliding support platform 5013 on the sliding support plate 503 to move up and down, and at the same time driving the vertical grouting pipe 501 moves up and down accordingly. During the upward movement of the vertical grouting pipe 501, the fixed support ring 501b touches the lower surface of the lower fixed support plate 504, thereby preventing the vertical grouting pipe 501 from moving further upward, so that the opening position of the grouting nozzle 5011 and the grouting port 100 can be quickly adjusted to maintain a suitable distance position, and the distance is monitored by the distance sensor 501e. In addition, during the process of the grouting nozzle 5011 injecting slurry into the grouting port 100 for reinforcement, the distance sensor 501e is used to detect the relative distance of the liquid level rise, and transmit the data of the relative liquid level rise to the PLC controller to control the grouting pump 3 to perform grouting operation.

[0028] In the present invention, Figure 3 and Figure 4 As shown, a buffer spring 501c is provided on the surface of the fixed support ring 501b and is sleeved on the outer wall of the vertical grouting pipe 501. A limit support ring 501d that is movably sleeved on the outer wall of the vertical grouting pipe 501 is connected to the upper end of the buffer spring 501c. During the process of the lifting and moving cylinder 506 pushing the sliding support plate 503 to move on the sliding guide column 505, the limit support ring 501d touches the lower surface of the lower fixed support plate 504, so that the limit support ring 501d slides relative to the sliding guide column 505 and squeezes the buffer spring 501c, so that the limit support ring 501d touches the lower surface of the lower fixed support plate 504 to restrict the vertical grouting pipe 501 from moving upward, thereby being effectively buffered.

[0029] In the present invention, Figure 1 and Figure 2As shown, a boost port 401 and a feeding port 402 are respectively provided on the top of the slurry collection box 4, the boost port 401 is connected to the boost pump 6 through a boost pipe, a sealing cover 403 is provided on the feeding port 41, and a slurry filter 404 is provided at the bottom end of the interior of the slurry collection box 4, the slurry filter 404 is used to filter larger particles in the slurry, and the boost pipe 401a extending from the boost port 401 into the slurry collection box 4 extends under the slurry filter 404, and the high-pressure airflow generated by the boost pump 6 stirs the concrete slurry in the slurry collection box 4 through the boost pipe 401a and increases the internal pressure, thereby increasing the grouting pressure of the slurry ejected from the straight grouting pipe 501 at the bottom end of the slurry collection box 4, and a switch valve 44 is provided on the slurry outlet at the bottom end of the slurry collection box 4; water can be added to the feeding port 402 to slurry the slurry collection box 4 After cleaning or mixing the additive mixture with the concrete reward through the feeding port, the sealing cover 403 tightly seals the feeding port 402, and the pressure can be increased to the slurry collection box 4 through the booster pump 6, so that the slurry flow in the slurry collection box 4 can be rapidly increased, and the slurry flow speed in the hose 22 is accelerated, and the pressure of the slurry sprayed out of the vertical grouting pipe 501 is increased, thereby increasing the pressure during pouring and strengthening, accelerating the speed of spraying and strengthening, improving work efficiency and strengthening quality. During the roadside strengthening and reinforcement operation, the switch valve 44 at the bottom of the slurry collection box 4 is opened, and the booster pump 6 is immediately started to transport the slurry to the slurry collection box 4, and the stirring motor 25 at the top of the slurry storage tank 2 drives the mixing paddle 24 to stir the slurry in the slurry storage tank 2, and then the slurry sprayed out from the grouting nozzle 5011 connected to the outlet of the straight grouting pipe 501 is used for reinforcement.

[0030] Combine Figures 1 to 4The grouting control process of the intelligent equipment for reinforcing and strengthening highway roadbed and pavement of the present invention is as follows: slurry is fed into the slurry storage tank 2 and stirred evenly, the movable frame 1 is moved to the front of the construction position of the grouting port 100, the grouting nozzle 5011 of the grouting assembly 5 is adjusted to extend into the grouting hole 10, the switch valve 44 is opened, the grouting pump 3 is started, and the slurry in the slurry storage tank 2 is transported to the slurry collection box 4, the liquid level and pressure of the slurry input into the slurry collection box 4 are detected and sent to the PLC controller provided in the control box 10 for judgment and analysis, and the booster pump 6 is started according to the liquid level and pressure, so that the concrete slurry in the slurry collection box 4 is quickly injected into the grouting hole 10 through the hose 22, the grouting pipe 501 and the grouting nozzle 5011, and the pavement gap is reinforced with grouting reinforcement operation; more specifically: the slurry is fed into the grouting tank 2 and the grouting nozzle 5011 is adjusted to extend into the grouting hole 10, and the switch valve 44 is opened, the grouting pump 3 is started, and the slurry in the slurry storage tank 2 is transported to the slurry collection box 4, and the liquid level and pressure of the slurry input into the slurry collection box 4 are detected and sent to the PLC controller provided in the control box 10 for judgment and analysis, and the booster pump 6 is started according to the liquid level and pressure, so that the concrete slurry in the slurry collection box 4 is quickly injected into the grouting hole 10 through the hose 22, the grouting pipe 501 and When transported to the slurry collection box 4, the slurry position sensors 43 at different positions continuously detect the first liquid level height and the second liquid level height of the slurry sent into the slurry collection box 4. When the first liquid level height is within the preset height range, the booster pump 6 is started to increase the pressure in the slurry collection box 4 so that the slurry is pressurized and grouting is performed through the hose 22, the grouting pipe 501 and the grouting nozzle 5011. At the same time, the first pressure in the slurry collection box 4 is obtained and judged by the first pressure sensor 42 and the duration of the first pressure is recorded. When the grouting pressure reaches the required pressure for a specified time, the slurry height in the grouting port 100 detected by the distance measuring sensor 501e is used to judge whether the grouting hole is full. If it is full, the grouting pump 3 and the booster pump 6 are stopped in turn, and the grouting is stopped. If it is not full, the operating power of the grouting pump 3 is adjusted to increase the slurry.

[0031] In an embodiment of the present invention, if the first pressure is greater than the preset pressure, the power of the grouting pump 3 is adjusted to reduce the amount of slurry sent into the slurry collection box 4, thereby achieving the purpose of accurately adjusting the slurry delivery flow rate; if the second liquid level is greater than the preset height range of 15%-20%, the return pump 232 is started to extract the excess slurry in the slurry collection box 4 and return it to the slurry storage tank 2, and the density sensor 233 is used to detect whether the density of the slurry is greater than the preset slurry density. If it is greater than the preset slurry density, the water-cement ratio of the slurry is adjusted, thereby providing a basis for dynamic adjustment of the water-cement wall of the slurry, and the second pressure in the slurry return pipe 23 is detected by the second pressure sensor 230, and the second slurry flow in the slurry return pipe 23 is detected by the second flow sensor 231, and the size of the pressure control valve 234 is adjusted according to the second pressure and the second slurry flow, thereby adjusting the grouting pressure, thereby avoiding damage to the injection tank propeller pump and the booster pump.

[0032] In the present invention, the pressure is controlled by setting the grouting pressure range to the PLC controller. During the reinforcement grouting reinforcement process, the first slurry flow of the slurry flowing through the first feed pipe 20 is detected by the first flow sensor 200. The operating power of the entire grouting pump 3 is adjusted according to the real-time monitoring and collection of the first slurry flow and the first pressure during grouting, so that the grouting pressure is controlled between 0.2Mpa and 0.6Mpa. In this way, the changes in grouting pressure and grouting flow can be timely understood by obtaining the grouting pressure and grouting volume in real time; the operating power of the grouting pump 3 can be adjusted in time to maintain the stability of the grouting pressure to the greatest extent. After the grouting reinforcement is completed, the processing equipment moves the reinforcement intelligent equipment to scrape the surface of the injected slurry flat, so that the slurry is flush with the road surface, and the grouting treatment is smoother and more beautiful.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
