Description

Technical Field

[0001] The present invention relates to the technical field of intelligent drilling rigs, and particularly to an intelligent drilling rig for road construction. Background Art

[0002] When a road bears the repeated load pressure of vehicles, especially in sections where heavy vehicles frequently pass. The wheel pressure of the vehicle will generate a complex stress distribution on the road surface. For example, when a large truck passes by, a large pressure is generated at the contact area between its tire and the road surface. The long-term action of vehicle loads will cause the fatigue of road surface materials. Just like stretching a rubber band repeatedly, when it reaches a certain number of times, the rubber band will break. Similarly, under the repeated load action, the road surface materials will gradually generate fatigue cracks. At the beginning, they may be fine mesh cracks. As the vehicle continues to pass, the cracks will gradually expand and extend.

[0003] The generation of cracks means that the integrity of the road surface structure is damaged. When directly filling the slurry on the crack surface, it is very difficult for the slurry to penetrate deep into the crack. Especially for some deeper, thinner or winding cracks, the slurry may only stay on the surface or in the shallow part and cannot fully fill the crack. After drilling, the grouting pipe can penetrate into the crack interior or the corresponding position of the foundation, providing a clear injection channel for the slurry, enabling the slurry to spread and fill more smoothly along the crack or the pores of the foundation under the action of pressure, ensuring that the crack is fully grouted from the inside to the outside. Usually, it is necessary to drill holes and grout in the crack area. After drilling and grouting, the slurry penetrates deep into the crack. When the slurry solidifies, it will bond the road surface structures on both sides of the crack together again.

[0004] The existing drilling and grouting are usually carried out manually. The staff needs to first find the cracks on the road surface, measure the depth of the cracks, then control the drilling rig to drill holes in the crack area. After drilling, the drill bit of the drilling rig is pulled out, and the grouting pipe is inserted into the hole to grout the crack. Until the slurry injection is completed, the staff pulls it out. This drilling and grouting procedure is cumbersome and takes too much time to drill and grout the cracks in an area, reducing the working efficiency of drilling and grouting.

[0005] Therefore, it is very necessary to have an intelligent drilling rig for road construction with high drilling and grouting efficiency and capable of automatically finding road cracks. Summary of the Invention

And according to the degree of cracking of the crack, an accurate amount of slurry is extracted and injected into the interior of the crack, effectively preventing the phenomenon of too much or too little injected slurry, achieving the effect of saving resources.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-9 , the present invention provides a technical solution: an intelligent drill for road construction, including a transfer vehicle 1. A camera 5 for photographing the ground is obliquely and fixedly connected to the lower side of the transfer vehicle 1. A power supply box 2 for storing power is fixedly connected to the upper side of the transfer vehicle 1. A control box 3 is provided on one side of the power supply box 2 and the control box 3 is fixedly connected to the transfer vehicle 1.

[0020] The adjusting mechanism 7 includes two support frames 71 fixedly connected to the upper side of the transfer vehicle 1. A first electric slide rail 72 is fixedly connected to the upper side of each support frame 71. The sliding end of the first electric slide rail 72 is fixedly connected to a second electric slide rail 75. A drilling and grouting assembly 76 is provided at the sliding end of the second electric slide rail 75. A slider 77 is fixedly connected to one side of the drilling and grouting assembly 76. A third electric slide rail 73 is fixedly connected to one side of the slider 77. The sliding end of the third electric slide rail 73 is fixedly connected to a connecting plate 78. A probe 74 is fixedly connected to the inside of the connecting plate 78. A sliding groove 11 is provided on one side of the transfer vehicle 1. The slider 77 is slidably connected to the sliding groove 11.

[0021] Supplementary description based on the above structure is as follows. The first electric slide rail 72 is used to drive the drilling and grouting assembly 76 and the probe 74 to slide along the chute 11, so that the probe 74 is aligned with the crack and the drill bit 765 is aligned above the crack respectively. The sliding of the sliding end of the second electric slide rail 75 is used to drive the drill bit 765 to move downward, so as to drill holes in the cracks of the road. The sliding of the sliding end of the third electric slide rail 73 is used to drive the probe 74 to move downward, so that the probe 74 is inserted into the crack and the depth of the crack is obtained.

[0022] The drilling and grouting assembly 76 includes a fixed cylinder 763 fixedly connected to the sliding end of the second electric slide rail 75. A second motor 761 is fixedly connected to the upper side of the fixed cylinder 763. The output end of the second motor 761 penetrates the fixed cylinder 763 and is fixedly connected with a screw column 766. A number of first spiral grooves 7661 are evenly arranged on the outer side of the screw column 766. A positioning cylinder 762 and a slurry passing cylinder 764 are respectively arranged on the outer side of the screw column 766. The upper side of the positioning cylinder 762 is fixedly connected with the fixed cylinder 763. The lower side of the positioning cylinder 762 is slidably connected with the slurry passing cylinder 764 through a T-shaped block. The lower side of the screw column 766 is fixedly connected with a drill bit 765. A second spiral groove 7651 is arranged on the outer side of the drill bit 765. A number of slurry spraying valves 767 are evenly and fixedly connected to the outer side of the slurry passing cylinder 764. Slurry passing grooves 7641 are arranged inside both the slurry passing cylinder 764 and the positioning cylinder 762. A slurry inlet valve 769 is fixedly connected to the outer wall above the slurry passing groove 7641. A water inlet valve 768 is fixedly connected to the inner wall above the slurry passing groove 7641.

[0023] Supplementary description based on the above structure is as follows. The rotation of the output end of the second motor 761 is used to drive the screw column 766 to rotate, and then drive the drill bit 765 to rotate. When the drill bit 765 drills a hole, when the screw column 766 rotates at a high speed, the material will be affected by the centrifugal force. The centrifugal force pushes the material towards the side wall of the second spiral groove 7651, so that it clings to the groove wall. With the continuous rotation of the screw column 766, the material is driven by the centrifugal force and continuously moves upward along the trajectories of the second spiral groove 7651 and the first spiral groove 7661, and finally is transported to the external environment. The slurry feeding mechanism 6 transports the slurry to the slurry inlet valve 769, and then enters the inside of the slurry passing groove 7641 through the slurry inlet valve 769. The slurry spraying valve 767 is used to spray the slurry inside the slurry passing groove 7641 into the surrounding cracks.

[0024] A material passing groove 7642 is provided at the center below the grouting cylinder 764. A retaining ring 7643 is fixedly connected to the upper side of the drill bit 765, and the retaining ring 7643 is in close contact with the grouting cylinder 764. Two L-shaped sliders 7645 are respectively fixedly connected to the lower side of the retaining ring 7643. Two L-shaped chutes 7646 are respectively provided inside the drill bit 765. The L-shaped sliders 7645 are slidably connected to the L-shaped chutes 7646. Two grouting holes 7644 are respectively provided below the grouting cylinder 764. The grouting holes 7644 communicate with the grouting groove 7641, and the material passing groove 7642 communicates with the second spiral groove 7651.

[0025] The supplementary description based on the above structure is as follows. When the drill bit 765 moves downward to drill a hole, the L-shaped slider 7645 slides downward and presses against the bottom surface of the L-shaped chute 7646, and the other end of the grouting hole 7644 is blocked by the drill bit 765. When the drill bit 765 moves upward and disengages from the hole, the L-shaped slider 7645 slides upward and presses against the top surface of the L-shaped chute 7646. At this time, the other end of the grouting hole 7644 communicates with the material passing groove 7642.

[0026] Since the L-shaped slider 7645 is only slidably connected to the L-shaped chute 7646 up and down, when the screw column 766 drives the drill bit 765 to rotate, it will indirectly drive the grouting cylinder 764 to rotate.

[0027] In the initial state, the bottom end of the probe 74 and the bottom end of the drill bit 765 are 5 mm away from the ground. When it is necessary to drill and grout the cracks on the road, the transfer vehicle 1 starts to move forward. Every time the transfer vehicle 1 moves a certain distance, the camera 5 takes a photo and gives it to the judgment module. A certain distance is the shooting width of the camera 5 until the camera 5 shoots a crack on the roadside surface. The judgment module judges that there is a crack in this area that needs to be drilled and grouted. The first electric slide rail 72 drives the probe 74 to move until the camera 5 shoots that the lower end of the probe 74 is directly above the crack. The judgment module judges that the crack depth can be measured at this time. The sliding of the sliding end of the third electric slide rail 73 drives the probe 74 to move downward. A pressure sensor is provided at the bottom end of the probe 74. When the bottom end of the probe 74 presses against the bottom end of the crack, the probe 74 is driven by the third electric slide rail 73 to move upward for return. The pressure sensor emits a signal to the judgment module, and the judgment module judges that the calculation of the crack depth can start. According to the distance that the sliding end of the third electric slide rail 73 moves downward from the start to the end, the length of the crack is obtained. Usually, the drilling depth is about 20 cm deeper than the crack depth.

[0028] Six groups of slurry spraying valves 767 are evenly arranged on the surface of the slurry passing cylinder 764. The distance between each group of slurry spraying valves 767 is set to 20 cm. When the second motor 761 controls the drill bit 765 to rotate and the second electric slide rail 75 controls the drill bit 765 to drill downward, the slurry feeding mechanism 6 transports the slurry to the slurry inlet valve 769, and then enters the inside of the slurry passing groove 7641 through the slurry inlet valve 769 to pre-fill the inside of the slurry passing groove 7641 and fill the inside of the slurry passing groove 7641 with slurry. The control box 3 adds twenty centimeters to the length of the crack, then divides it by twenty and rounds up to obtain the minimum number of groups of slurry spraying valves 767 that need to be opened from the bottom. When the drill bit 765 reaches the required drilling depth, at least the previously calculated number of groups of slurry spraying valves 767 are sequentially opened from the bottom. The slurry inside the slurry passing groove 7641 passes through the opened slurry spraying valves 767 and is sprayed inside each crack, thereby filling each crack with slurry.

[0029] When the drill bit 765 moves downward to drill a hole, the L-shaped slider 7645 slides downward and presses against the bottom surface of the L-shaped chute 7646, and the other end of the slurry passing hole 7644 is blocked by the drill bit 765. At this time, the other end of the slurry passing hole 7644 cannot discharge slurry. After each crack is filled with slurry, all the slurry spraying valves 767 are closed, and the second electric slide rail 75 controls the drill bit 765 to move upward. When the drill bit 765 moves upward and disengages from the hole, the L-shaped slider 7645 slides upward and presses against the top surface of the L-shaped chute 7646. At this time, the other end of the slurry passing hole 7644 communicates with the material passing groove 7642. The retaining ring 7643 is used to block the slurry to prevent the slurry from leaking. The slurry inside the slurry passing groove 7641 flows through the slurry passing hole 7644 into the inside of the material passing groove 7642, and the slurry flows downward and enters the hole through the second spiral groove 7651 to fill the drilled hole with slurry until the drill bit 765 completely leaves the hole and returns to its position, and the slurry inlet valve 769 is closed. At this time, the drilled hole and the surrounding cracks are all filled.

[0030] The transfer vehicle 1 drives the camera 5 to move. During the movement, the camera 5 continuously takes pictures of the ground to find cracks. After finding the cracks, the camera 5 accurately finds the position where the probe 74 needs to be inserted through shooting. The probe 74 measures the depth of the cracks. After the drill bit 765 finishes drilling, without pulling out the drill bit 765, directly adjust an appropriate number of slurry spraying valves 767 to open. The slurry inside the slurry passing groove 7641 passes through the opened slurry spraying valves 767 and is sprayed inside each crack, thereby filling each crack with slurry, shortening the time of drilling and grouting, achieving the effect of high drilling and grouting efficiency. After the grouting is completed, the second electric slide rail 75 can not only drive the drill bit 765 to move upward and disengage from the hole, but also drive the slurry inside the slurry passing groove 7641 to flow into the hole through the slurry passing hole 7644, the material passing groove 7642, and the second spiral groove 7651 in sequence to fill the hole simultaneously.

[0031] Example 2. Since the depth, range, and width of the cracks on each road are different, the amount of grout required is also different. When grouting manually, it is difficult to control the amount of grout, which easily causes a large amount of grout to be injected into cracks with a short width, small range, and shallow depth, resulting in waste of grout, and a small amount of grout to be injected into cracks with a long width, wide range, and deep depth, resulting in insufficient grout filling. Therefore, the following structure is designed to solve the above technical problems.

[0032] The cleaning mechanism 4 includes a water tank 41 fixedly connected to the upper side of the power supply box 2. A first water pump 42 is fixedly connected to the upper side of the water tank 41, and the input end of the first water pump 42 is connected to the water tank 41 through a pipeline.

[0033] Based on the above structure, the following is a supplementary description. The first water pump 42 is used to pump the water source inside the water tank 41 into the weighing bucket 63.

[0034] The grout feeding mechanism 6 includes a weighing bucket 63 fixedly connected to the upper side of the transfer vehicle 1. The weighing bucket 63 is connected to the output end of the first water pump 42 through a pipeline. A first motor 61 is fixedly connected to the upper side of the weighing bucket 63. There is a grout inlet cover 62 on one side of the first motor 61, and the grout inlet cover 62 is fixedly connected to the weighing bucket 63. The output end of the first motor 61 is fixedly connected to a stirring shaft 64. A plurality of stirring blades 65 are evenly and fixedly connected to the outer side of the stirring shaft 64. An outlet valve 66 and a grout outlet valve 67 are respectively fixedly connected to the lower side of the weighing bucket 63. A second water pump 68 is provided on one side of the weighing bucket 63, and the input end of the second water pump 68 is connected to the grout outlet valve 67 through a pipeline. The output end of the second water pump 68 is fixedly connected to a pressure valve 69, and the output end of the pressure valve 69 is connected to the input end of the grout inlet valve 769 through a pipeline.

[0035] Based on the above structure, the following is a supplementary description. The weighing bucket 63 is used to weigh the grout inside. The rotation of the output end of the first motor 61 is used to control the rotation of the stirring blades 65, thereby stirring the grout inside the weighing bucket 63. The second water pump 68 is used to pump the grout out of the weighing bucket 63 and pressurize it through the pressure valve 69, so as to transport it into the grout passage 7641 under high pressure. However, when the crack width is the same, a higher grouting pressure can make the grout penetrate deeper into the formation, which may increase the grouting volume. But for cracks with a larger width, too high a grouting pressure may cause the grout to flow too fast in the crack, which may not necessarily effectively increase the filling volume and may also cause other problems, such as ground heave. Therefore, for cracks with a larger width, the grouting pressure needs to be appropriately adjusted.

[0036] After all the cracks on the road are filled, the first water pump 42 pumps the water source inside the water tank 41 into the weighing bucket 63 to clean the inside of the weighing bucket 63. After the cleaning of the weighing bucket 63 is completed, the slurry inlet valve 769 and the water inlet valve 768 are opened. The second water pump 68 pumps out the sewage inside the weighing bucket 63, pressurizes it through the pressure valve 69, and conveys it to the inside of the slurry passage groove 7641 at high pressure. At this time, all the slurry spraying valves 767 are opened. Part of the water source first impacts on the surface of the spiral column 766 through the water inlet valve 768, and then flows downward along the first spiral groove 7661 and the second spiral groove 7651 to clean the surfaces of the first spiral groove 7661 and the second spiral groove 7651. Another part of the water source passes through the slurry passage groove 7641 to wash the slurry inside the slurry passage groove 7641 and is discharged through the slurry spraying valve 767.

[0037] When it is necessary to control the usage amount of the slurry according to the depth, range and width of the cracks on the road, the probe 74 first detects the depth of the cracks and converts it into an electrical signal and sends it to the control box. Then the camera 5 takes a shot of the cracks. After the camera 5 takes the image of the crack surface, it will convert the image into an electrical signal and send it to the judgment module. The judgment module will compare it with the recognition photos of different widths and crack distribution ranges of the cracks in the internal database, pre-identify the state of the crack surface, and classify the cracking degree of this crack into slight crack, medium crack and severe crack according to the taken photo of the crack surface and the detected crack depth.

[0038] When the camera 5 captures that the width of the crack is too short and the range is too small, and the depth of the crack is too shallow, the judgment module determines that the cracking degree of this crack is a slight crack. The second water pump 68 pumps out one-sixth of the slurry inside the weighing bucket 63 and injects it into the crack through the slurry spraying valve 767.

[0039] When the camera 5 captures that the width of the crack is too short and the range is too small, and the depth of the crack is too deep, the judgment module determines that the cracking degree of this crack is a medium crack. The second water pump 68 pumps out one-third of the slurry inside the weighing bucket 63 and injects it into the crack through the slurry spraying valve 767.

[0040] When the camera 5 captures that the width of the crack is too long and the range is too small, and the depth of the crack is too shallow, the judgment module determines that the cracking degree of this crack is a medium crack. The second water pump 68 pumps out one-third of the slurry inside the weighing bucket 63 and injects it into the crack through the slurry spraying valve 767.

[0041] When the camera 5 captures that the width of the crack is too short and the range is too large, and the depth of the crack is too shallow, the judgment module determines that the cracking degree of this crack is a medium crack. The second water pump 68 pumps out one-third of the slurry inside the weighing bucket 63 and injects it into the crack through the slurry spraying valve 767.

[0042] When the camera 5 captures that the width and range of the crack are too long and the depth of the crack is too deep, the judgment module determines that the degree of cracking of this crack is a severe crack, and the second water pump 68 pumps out half of the slurry inside the weighing bucket 63 and injects it into the crack through the grouting valve 767.

[0043] The camera 5 captures the cracks on the road surface in real time, and the probe 74 detects the depth of the cracks. After the camera 5 captures the image of the crack surface, it will convert the image into an electrical signal and send it to the judgment module. The judgment module will compare it with the identification photos of cracks with different widths and crack distribution ranges in the internal database, pre-identify the state of the crack surface, and according to the captured photo of the crack surface and the detected crack depth, classify the degree of cracking of this crack into minor cracks, medium cracks and severe cracks, and inject an accurate amount of slurry into the crack according to the degree of cracking of the crack, effectively preventing the phenomenon of too much or too little injected slurry, and achieving the effect of saving resources.
