Description

Technical Field

[0001] The invention relates to the technical field of column installation, in particular to a drilling device for highway guardrail column construction and an operating method thereof. Background Art

[0002] The construction of highway guardrail posts is a complex and meticulous process. First, professional measuring instruments, such as total stations, are used to accurately measure and locate the positions of guardrail posts. The exact positions of posts are marked on the ground and marked with markings or markers. According to the design requirements, holes are drilled at the predetermined positions using a drilling machine. After the drilling is completed, a pile driver is used to drive the guardrail posts into the holes to ensure the verticality and stability of the posts. For areas with poor geological conditions, special piling methods or reinforcement measures may be required. Connectors and fixings, such as beams, brackets, bolts, etc., are installed on the posts to ensure that the connectors and fixings are firmly installed and meet the design requirements. Then, concrete pouring and maintenance work is carried out. After the pouring is completed, anti-corrosion treatment, quality inspection and acceptance are carried out. During the drilling process, first start the drilling equipment, let the engine idle for a while, check whether the instruments and indicator lights are normal, and after confirming that the equipment is operating normally, slowly adjust the drill bit position to align it with the drilling position. During the drilling process, keep the drill bit rotating and advancing at a uniform speed, always pay attention to the working condition of the drill rod, and avoid the drill rod from getting stuck or bending. After the drilling is completed, check whether the parameters such as the diameter, depth and verticality of the borehole meet the design requirements, and then use a cleaning tool to clean up the soil, gravel and other debris in the borehole. However, in the actual drilling process, due to the uneven hardness of some strata or the existence of soft and hard interlayers, the drill bit may be unevenly stressed during the drilling process. In order to ensure the smooth drilling of the drill bit, greater drilling pressure and torque are often applied. As the number of uses increases, the drill rod is prone to bending. The bent drill rod is prone to causing the borehole to be easily deflected and the aperture changes during the drilling process, affecting the subsequent installation of guardrail posts. To this end, we propose a drilling device for highway guardrail post construction and an operating method thereof. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 13The present invention provides a technical solution: a drilling device for the construction of highway guardrail columns. The present invention makes corresponding improvements to the technical problems in the background technology, including a vehicle body 1, a power mechanism 2 fixedly installed on the vehicle body 1, and a support part 3 slidably connected to the side wall of the vehicle body 1 is installed on the side wall, wherein the support part 3 is fixedly connected to the power mechanism 2, and a stand 4 slidably connected to the side wall is installed on the support part 3, and a servo motor 5 is fixedly installed on the stand 4, wherein the output end of the servo motor 5 is fixedly connected to the end of a drill rod 6, the power mechanism 2 controls the support part 3 to adjust the position, and then the support part 3 drives the stand 4 and the mechanical parts thereon to adjust the position, and two annular disc racks 7 are fixedly installed on the side wall of the support part 3, and the two annular disc racks 7 are fixedly installed on the side wall of the support part 3. The central axis of the disc rack 7 coincides with the axis of the drill rod 6. A testing sleeve 71 is fixedly installed on the annular disc rack 7 close to the drilling surface, and a rubber ring sleeve 72 is installed inside the testing sleeve 71, wherein the inner wall of the rubber ring sleeve 72 is in contact with the drill rod 6, and a pressure element 73 is also fixedly installed inside the testing sleeve 71, and the pressure element 73 is in contact with the outer wall of the rubber ring sleeve 72; it should be noted that a screw mechanism is also installed inside the support part 3, and the gantry 4 can be directional position adjusted under the action of the screw mechanism. Since the screw mechanism is a drilling device component in the prior art, the present invention does not describe it too much. The gantry 4 can be adjusted in position through the screw mechanism, and the servo motor 5 and the drill rod 6 on the gantry 4 can be adjusted in position; Combined with Figure 3 and attached Figure 4 As shown, during the drilling process, the power mechanism 2 first controls the support part 3 to adjust the position. When the end of the drill rod 6 (i.e., the drill bit) is close to the ground, the control stand 4 is adjusted through the screw mechanism, so that the end of the drill rod 6 contacts the ground, and the drill rod 6 is made to drill under the action of the servo motor 5. During the drilling process, the stand 4 is adjusted to make the drill rod 6 penetrate into the ground. Since the testing sleeve 71 is fixedly mounted on one of the annular disc racks 7 (the annular disc rack 7 is the annular disc rack 7 close to the drilling surface), and the annular disc rack 7 is fixedly mounted on the side wall of the support part 3, when the drill rod 6 is adjusted in position, the rubber ring sleeve 72 plays a role in protecting the drill rod 6. When the drill rod 6 is bent, the rubber ring sleeve 72 will be squeezed. When the rubber ring sleeve 72 is squeezed, a force will be applied to the pressure element 73. The pressure element 73 is subjected to the force to change its value, and then the pressure element 73 is transmitted to the central control device in the form of an electrical signal to inform the staff that the drill rod 6 is bent. In order to detect the holes drilled by the drill rod 6, the present invention is designed as follows: a plurality of detection sleeves 8 are arranged under one of the annular racks 7, a detection shaft 81 slidably connected to the inner wall thereof is installed on the top of each detection sleeve 8, and one end of the detection shaft 81 is located outside the detection sleeve 8, and a clamping unit 9 for limiting the detection shaft 81 is also arranged inside the detection sleeve 8, and an adjusting unit 10 for controlling the position adjustment of the detection sleeve 8 is also arranged on the annular rack 7, the detection sleeve 8 is adjusted in position by the adjusting unit 10, and the hole quality can be effectively detected by the detection shaft 81. As a further limitation of the present invention, the clamping unit 9 includes a clamping seat 91 symmetrically arranged inside the detection sleeve 8, and a clamping seat 91 is installed on the clamping seat There is a clamping shaft body 92 rotatably connected thereto, wherein a limit plate frame 93 is fixedly installed at one end of the detection shaft body 81 located inside the detection sleeve 8, and a plurality of clamping blocks 94 are fixedly installed on both sides of the limit plate frame 93, and the clamping blocks 94 are arranged in a right-angled triangle shape, wherein the clamping shaft body 92 is located between two of the clamping blocks 94, and the clamping shaft body 92 is located on the movement trajectory of the clamping blocks 94, and a buffer spring 95 is connected between the limit plate frame 93 and the inner wall of the detection sleeve 8, and an extension shaft body 96 is also fixedly installed on the clamping seat body 91, and the end of the extension shaft body 96 passes through the inner wall of the top of the detection sleeve 8 and extends to the outside, wherein a spring body 97 is connected between the clamping seat body 91 and the inner wall of the detection sleeve 8, and it should be noted that a scale groove is also provided on the detection shaft body 81; Combined with Figure 6 As shown, the outer shape of the clamping block 94 is set in the shape of a right triangle. When the detection shaft 81 moves toward the inside of the detection sleeve 8, the inclined surface of the clamping block 94 will exert a force on the clamping shaft 92, so that the clamping shaft 92 drives the clamping seat 91 to squeeze the spring body 97; In order to facilitate the subsequent installation of the column, the present invention monitors whether the value of the inner diameter of the hole changes. The change in the value of the inner diameter of the hole is not only affected by the bending condition of the drill rod 6, but may also be related to the speed, quality, wear and other factors of the end of the drill rod 6 (i.e., the drill bit). As a further limitation in the present invention, the adjustment unit 10 includes a plurality of limit frames 101 fixedly installed between the two annular racks 7, the limit frames 101 correspond to the detection sleeve 8 one by one, and the end of the detection sleeve 8 is fixedly installed with a connecting shaft 102, and the connecting shaft 102 The end portion passes through one of the annular disc racks 7 and extends to the bottom of the other annular disc rack 7. A through groove (not shown in the figure) for limiting the connecting shaft body 102 is opened on one of the annular disc racks 7 (the annular disc rack 7 is the annular disc rack 7 close to the drilling surface). An electromagnetic assembly 103 is installed on the annular disc rack 7 located above the connecting shaft body 102, and a sliding frame 104 is arranged below the electromagnetic assembly 103. A sliding block 105 that is slidably connected to the inner wall of the sliding frame 104 is fixedly installed at the end of the connecting shaft body 102, and the sliding frame 104 The top is a magnetic surface, and the electromagnetic assembly 103 generates magnetism on the top of the sliding frame 104 when it is energized. It should be noted that the magnetic pole of the electromagnetic assembly 103 can be changed by changing the energization direction of the electromagnetic assembly 103. Since the magnetic pole change of the electromagnetic assembly 103 is a prior art, the present invention does not describe it in detail. The limiting frame 101 is also provided with a guide shaft body 106 fixedly connected to the two annular racks 7, and the sliding frame 104 is limitedly slidable on the guide shaft body 106, and the telescopic part 10 is symmetrically installed on the connecting shaft body 102. 7, and guide grooves 11 for limiting the telescopic portion 107 are provided on both sides of the limiting frame 101, the guide grooves 11 in the present invention include a sliding area 111, an inclined downward area 112, a descending area 113, an inclined upward area 114 and a reset area 115, wherein a guide panel 116 is fixedly installed at the intersection of the sliding area 111 and the reset area 115 and at the intersection of the descending area 113 and the inclined upward area 114, wherein one side of the guide panel 116 is an inclined surface and the other side is a right-angle surface, combined with the attached Fig. 9 As shown, the guide panel 116 (located at the intersection of the sliding area 111 and the reset area 115) is a right-angled surface on the side located in the sliding area 111, and is an inclined surface on the side located in the reset area 115; the guide panel 116 (located at the intersection of the descending area 113 and the inclined upward area 114) is an inclined surface on the side located in the descending area 113, and is a right-angled surface on the side located in the inclined upward area 114.

[0019] Combined with Figure 3As shown, in the initial state, the telescopic portion 107 is located in the sliding area 111. After the drilling work of the drill rod 6 is completed, the control stand 4 is controlled to move upward through the screw mechanism, so that the stand 4 drives the drill rod 6 to move upward during the ascending process, so that the drill rod 6 is located above the detection sleeve 8 (as shown in the attached figure). Fig.10 As shown), the electromagnetic component 103 is then energized to generate a repulsive force on the top of the sliding frame 104, so that the sliding frame 104 performs a directional movement under the action of the guide shaft 106. During the movement of the sliding frame 104, the sliding block 105 inside it moves synchronously with it, and then the telescopic portion 107 on the connecting shaft 102 moves along the trajectory of the sliding area 111. When it moves to the sliding area 111, it will enter the inclined downward area 112 under the action of the right-angle surface of the guide panel 116 (located at the intersection of the sliding area 111 and the reset area 115), and finally enter the descending area 113. During this process, the connecting shaft 102 will drive the detection sleeve 8, the detection shaft 81 and other related components to move closer, as shown in the attached figure. Fig.10As shown, at this time, the telescopic portion 107 is located in the inclined downward area 112. When the telescopic portion 107 enters the descending area 113, the diameter of the circular trajectory formed by the multiple detection shaft bodies 81 (that is, the intersection of the extended lines of the axes of the multiple detection shaft bodies 81 is the center of the circle, and the circular trajectory is made with the center of the circle to the end of the detection shaft body 81) is smaller than the diameter of the hole, and the telescopic portion 107 continues to move in the descending area 113. During this process, the detection sleeve 8 and the detection shaft body 81 are located in the hole. When the telescopic portion 107 enters the inclined downward area 113, the diameter of the circular trajectory formed by the multiple detection shaft bodies 81 is smaller than the diameter of the hole. When the detection shaft 81 is in the oblique upward area 114, the detection shaft 81 is completely inserted into the hole. Since the depth of the installation hole of the column is mostly fixed, the detection shaft 81 is generally close to the bottom of the hole. Then the power supply direction of the electromagnetic component 103 is changed so that the electromagnetic component 103 generates an attraction force on the sliding frame 104, and the telescopic part 107 moves along the trajectory of the oblique upward area 114 under the action of the right-angle surface of the guide panel 116, and then the detection shaft 81 moves toward the inner wall of the hole, and finally The detection shaft 81 contacts the inner wall of the hole and is contracted by the action of the inner wall of the hole. When the detection shaft 81 contracts toward the inside of the detection sleeve 8, the detection shaft 81 drives the limit plate frame 93 to squeeze the buffer spring 95, and the inclined surface of the clamping block 94 applies a force to the clamping shaft 92, so that the clamping shaft 92 drives the clamping seat body 91 to squeeze the spring body 97, and then the detection shaft 81 can move toward the inside of the detection sleeve 8, but when the detection shaft 81 moves in the opposite direction, the right angle of the clamping block 94 The detection shaft 81 cannot move to the outside of the detection sleeve 8, and when the telescopic portion 107 moves from the reset area 115 to the sliding area 111, the detection shaft 81 can record the minimum value of the aperture in the hole. When the detection shaft 81 leaves the hole, the staff can observe the scale value of the outer wall of the detection shaft 81. By comparing the scale values ​​of multiple detection shafts 81, the inner diameter value of the hole can be effectively understood, so that the staff can monitor the aperture value. In the actual drilling process, the ground gravel at the hole will be discharged outside the hole under the action of the chip discharge groove, that is, it is easy to accumulate near the hole, but too much gravel near the hole will increase the friction resistance between the drill rod 6 and the hole wall, thereby reducing the drilling speed. In order to overcome this resistance, the servo motor 5 needs to apply a larger drilling pressure and torque, which will not only increase energy consumption, but also reduce the drilling efficiency. If the drilling speed is too fast, the drilling pressure is too large, etc., the drill rod 6 may be subjected to excessive impact force or torque, thereby increasing the risk of bending. Based on this, the present invention is designed as follows: Combined with Figure 11-13As shown, an annular sleeve 12 is also fixedly installed at the bottom of the support part 3, and a circular frame 121 is arranged inside the annular sleeve 12 for limited movement inside the annular sleeve 12, wherein a telescopic shaft 122 is also fixedly installed on the outer wall of the circular frame 121, and an adjusting groove 13 is opened on the inner wall of the annular sleeve 12, wherein the adjusting groove 13 includes a plurality of arcuate grooves 131 and vertical grooves 132, and the arcuate grooves 131 and the vertical grooves 132 are in a connected state, wherein a guide panel 2 133 is fixedly installed at the intersection of one end of the arcuate groove 131 and the vertical groove 132, and one side of the guide panel 2 133 is an inclined surface, and the other side is a right-angle surface, and the telescopic shaft 122 is limited in the adjustment groove 13 and slides. The circular frame 121 is movable, wherein the top of the circular frame 121 is a magnetic surface, and a plurality of electromagnet bodies 123 are fixedly installed on the inner wall of the top of the annular sleeve 12, and the electromagnet bodies 123 generate magnetism on the magnetic surface of the circular frame 121 when energized, and a plurality of movable sliders 124 slidably connected to the inner wall of the circular frame 121 are also installed inside the circular frame 121, and a constant force spring 125 is connected between the movable slider 124 and the inner wall of the circular frame 121, wherein a magnetic shaft 126 is also fixedly installed on the movable slider 124, and a telescopic scraper 127 is connected to the end of the magnetic shaft 126, wherein a plurality of strong magnets 128 are fixedly installed at the bottom of the annular sleeve 12, and the strong magnets 128 are located on the descending trajectory of the magnetic shaft 126;It should be noted that, in the initial state, the telescopic scraper 127 is located above the ground and does not contact the ground. At this time, the drilled gravel will be discharged to the vicinity of the drill rod 6, that is, below the telescopic scraper 127. During the operation of the drill rod 6, the electromagnet body 123 is regularly controlled to be energized, so that the electromagnet body 123 produces a repulsive force on the magnetic surface of the circular frame 121, thereby causing the circular frame 121 to move downward in the annular sleeve 12. During the descent, the telescopic shaft body 122 will move along the trajectory of the vertical slot body 132, and then the circular frame 121 will drive the magnetic shaft body 126 and the telescopic scraper 127 at its end to move downward through the moving slider 124, so that the end of the telescopic scraper 127 contacts the ground, that is, the telescopic scraper 127 penetrates into the gravel. When the telescopic shaft body 122 enters the bottom of the vertical slot body 132, the magnetic shaft body 126 moves to the corresponding position of the strong magnet 128. The strong magnet 128 is used to repel the magnetic shaft body 1 26 generates an attraction force, so that the magnetic shaft 126 drives the telescopic scraper 127 to move toward the strong magnet 128 under the action of the moving slider 124. In this process, the telescopic scraper 127 will scrape the gravel from the vicinity of the hole to prevent the gravel from affecting the drilling of the drill rod 6, and also prevent the gravel from falling into the hole. The moving slider 124 will squeeze the constant force spring 125 during the movement. When the telescopic scraper 127 scrapes the gravel from the vicinity of the hole, the electromagnet body 123 changes the current direction to generate an attraction force on the circular frame 121, and then the telescopic shaft 122 will move along the trajectory of the arc groove 131 under the action of the guide panel 133, so that the circular frame 121 adjusts its angle, and then the telescopic scraper 127 also adjusts its angle accordingly, so that the subsequent telescopic scraper 127 can clean the remaining uncleaned areas to prevent the gravel near the hole from affecting the drilling of the drill rod 6. ;

The end of the telescopic scraper 127 contacts the ground and penetrates into the gravel. The telescopic shaft body 122 enters the bottom of the vertical slot body 132, and the strong magnet 128 generates an attractive force on the magnetic shaft body 126, so that the magnetic shaft body 126 drives the telescopic scraper 127 to move toward the strong magnet 128, and the telescopic scraper 127 scrapes the gravel from the vicinity of the hole; S3, the electromagnet body 123 changes the direction of the current to generate an attractive force on the circular frame 121, the telescopic shaft 122 moves along the trajectory of the arc-shaped groove 131 under the action of the second guide panel 133, the circular frame 121 adjusts its angle, and the telescopic scraper 127 adjusts its angle and cleans the remaining uncleaned areas; S4, after the drilling is completed, the drill rod 6 is located above the detection sleeve 8, and the electromagnetic assembly 103 is energized to generate a repulsive force on the top of the sliding frame 104.

When the telescopic portion 107 enters the inclined upward area 114, the detection shaft 81 is completely inserted into the hole, and then the power supply direction of the electromagnetic component 103 is changed so that the electromagnetic component 103 generates an attraction force on the sliding frame 104. The telescopic portion 107 moves along the trajectory of the inclined upward area 114 under the action of the right-angled surface of the guide panel 116, and the detection shaft 81 moves toward the inner wall of the hole, and finally contacts the inner wall of the hole and shrinks under the action of the inner wall of the hole. The detection shaft 81 drives the limit plate frame 93 to squeeze the buffer spring 95. When the detection shaft 81 moves in the opposite direction, the right-angled surface of the clamping block 94 is blocked by the clamping shaft 92. Then, when the telescopic portion 107 moves from the reset area 115 to the sliding area 111, the detection shaft 81 can record the minimum value of the aperture in the hole. By comparing multiple detection shafts 81, the inner diameter value of the hole can be understood. S6. After the detection is completed, the extension shaft 96 is pulled outward so that the clamping seat body 91 drives the clamping shaft body 92 to leave the motion track of the clamping block body 94. Under the action of the buffer spring 95, the clamping block body 94 causes the limit plate frame 93 to drive the detection shaft body 81 back to the initial position, that is, the detection is completed.
