Description

Technical Field

[0001] The present invention relates to the technical field of hole detection, and particularly to a device and method for detecting the perpendicularity of a hole. Background Art

[0002] After the hole is formed by an anchor drill, it is necessary to detect the perpendicularity of the hole to ensure the hole-forming quality. The existing detection methods are relatively complex, have high requirements for the visual perception of the inspectors, are difficult to control the accuracy, are prone to misjudgment, are difficult to measure the specific perpendicularity deviation value and direction, and the detection instrument is large in volume and heavy in weight and needs to be lifted and transported. Summary of the Invention

[0003] The purpose of the present invention is to provide a device and method for detecting the perpendicularity of a hole, which can relatively conveniently detect the perpendicularity deviation angle and deviation direction of the hole, and the detection device has a simple structure.

[0004] To solve the above technical problems, the present invention adopts the following solutions: A device for detecting the perpendicularity of a hole includes a fixed seat arranged at the hole entrance. At the center of the fixed seat, there is a telescopic rod that coincides with the center of the hole entrance. At the bottom end of the telescopic rod, there is an installation seat. Above the installation seat, there is a detection rod hinged to the telescopic rod. At one end of the detection rod adjacent to the hole wall, there is a ball. During the downward movement of the detection rod along the hole wall, the inclination angle changes following the perpendicularity of the hole wall. On the detection rod, there is an angle sensor for real-time sensing of the inclination angle of the detection rod. On the side of the installation seat, there is a distance sensor for real-time detection of the distance from the side of the installation seat to the hole wall.

[0005] In this solution, the fixed seat is installed at the orifice of the hole, and the telescopic rod is installed at the center of the fixed seat, making the telescopic rod coincide with the center of the orifice. Initially, it is considered that the axis of the hole is parallel to the hole wall, that is, there is no deviation angle in the hole wall. The hole can be vertical, inclined, or horizontal. The detection rod above the mounting seat can rotate. After the detection rod extends into the hole, the ball at its distal end contacts the hole wall. If the perpendicularity of the hole does not deviate, then the inclination angle of the detection rod will not change. If the perpendicularity of the hole deviates during the drilling process, then the side wall of the hole will tilt, and then the inclination angle of the detection rod will also change following the tilt state of the side wall. The angle sensor can detect the change in the inclination angle of the detection rod in real time. The distance sensor on the side of the mounting seat can detect the actual distance from the side of the mounting seat to the hole wall in real time, and this actual distance also changes following the tilt state of the hole wall. The length of the mounting seat is known. In this way, the inclination angle of the hole wall can be obtained based on the inclination angle of the detection rod, the length of the mounting seat, and the actual distance, and then the specific perpendicularity of the hole can be obtained. The telescopic rod descends in sections until it reaches the bottom of the hole, completing the detection of the perpendicularity of the entire hole. The entire detection process does not require manual detection by visual inspection and realizes automatic detection and calculation throughout the process. This device can conveniently detect the deviation angle and deviation direction of the perpendicularity of the hole, and the detection device has a simple structure.

[0006] Optionally, a spherical fixed sleeve is provided at one end of the detection rod adjacent to the hole wall, and the ball is movably arranged in the fixed sleeve.

[0007] Optionally, the lowermost end of the telescopic rod passes through the mounting seat, and a bottom plate is provided at the lower end of the telescopic rod at the bottom surface of the mounting seat. A driving assembly for driving the mounting seat to squeeze the detection rod inward is provided between the bottom plate and the mounting seat.

[0008] Optionally, a notch groove corresponding to the detection rod is provided on the top surface of the mounting seat, and the bottom surface of the notch groove is an inclined surface.

[0009] Optionally, the driving assembly includes a driving member and a transmission block. The top surface of the transmission block is in contact with the bottom surface of the mounting seat in an inclined straight surface, and the bottom surface of the transmission block is in contact with the flat straight surface of the bottom plate. The driving member drives the transmission block to move, and the movement of the transmission block drives the position of the mounting seat to change and squeezes the detection rod inward.

[0010] Optionally, a pelvic cavity is provided on the top surface of the bottom plate, the driving member is installed on the side wall of the pelvic cavity, and two transmission blocks are provided and symmetrically arranged in the pelvic cavity.

[0011] Optionally, the driving member is a cylinder or an electric cylinder, and the telescopic end of the driving member passes through the side wall of the pelvic cavity and contacts the side wall of the transmission block.

[0012] Optionally, the telescopic rod is an electric telescopic rod or a pneumatic telescopic rod.

[0013] Optionally, a rotary motor for driving the telescopic rod to rotate is provided on the top surface of the fixed seat.

[0014] A method for detecting the perpendicularity of a hole includes the following steps: S1: Install the telescopic rod at the central position of the fixed seat, and place the detection rod and the mounting seat in the hole. S2: Fix the fixed seat at the hole opening, and make the telescopic rod coincide with the center of the hole opening. S3: The telescopic rod extends into the hole section by section until it reaches the bottom of the hole. Each time it extends, the angle sensor detects the change in the inclination angle of the detection rod, and the distance sensor detects the actual distance from the side of the mounting seat to the hole wall. Combining the actual distance, the inclination angle of the detection rod, and the length of the mounting seat, the inclination angle of the hole wall is obtained. S4: Obtain the actual length of the inclined section of the hole wall according to the inclination angle of the hole wall. S5: The rotary motor drives the telescopic rod to rotate to obtain the inclination data of one week of the inclined section of the hole wall. According to the data of multiple inclined sections of the hole wall and the corresponding inclination angles, the three-dimensional space shape of the hole is fitted. S6: The telescopic rod retracts to recycle the detection device.

[0015] The beneficial effects of the present invention are as follows: In the present invention, during detection, after the detection rod extends into the hole, the ball at its distal end contacts the hole wall. If the perpendicularity of the hole does not deviate, then the inclination angle of the detection rod will not change. If the perpendicularity of the hole deviates during the drilling process, then the side wall of the hole will be inclined, and then the inclination angle of the detection rod will also change following the inclination state of the side wall. The angle sensor can detect the change in the inclination angle of the detection rod in real time, and the distance sensor on the side of the mounting seat can detect the actual distance from the side of the mounting seat to the hole wall in real time. This actual distance also changes following the inclination state of the hole wall. The length of the mounting seat is known. In this way, according to the inclination angle of the detection rod, the length of the mounting seat, and the actual distance, the inclination angle of the hole wall can be obtained, and then the specific perpendicularity of the hole can be obtained. The telescopic rod descends section by section until it reaches the bottom of the hole, completing the detection of the perpendicularity of the entire hole. The entire detection process does not require manual detection by visual inspection, and automatic detection and calculation are achieved throughout the process. This device can more conveniently detect the deviation angle and deviation direction of the perpendicularity of the hole, and the structure of the detection device is simple.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] A pore verticality detection device includes a fixed seat 1 arranged at the pore opening. At the center of the fixed seat 1, there is a telescopic rod 3 that coincides with the center of the pore opening. At the bottom end of the telescopic rod 3, there is a mounting seat 11. Above the mounting seat 11, there is a detection rod 4 hinged to the telescopic rod 3. At one end of the detection rod 4 adjacent to the pore wall, there is a ball 13. During the downward movement of the detection rod 4 along the pore wall, the inclination angle changes following the verticality of the pore wall. On the detection rod 4, there is an angle sensor 5 for sensing the inclination angle of the detection rod 4 in real time. On the side of the mounting seat 11, there is a distance sensor 6 for detecting the distance from the side of the mounting seat 11 to the pore wall in real time.

[0022] In this embodiment, the fixed seat 1 is installed at the orifice of the hole, and the telescopic rod 3 is installed at the central position of the fixed seat 1, so that the telescopic rod 3 coincides with the center of the orifice of the hole. This device can detect the perpendicularity of vertical, inclined or horizontal holes. Taking the vertical hole as an example in this embodiment, the detection rod 4 above the mounting seat 11 can rotate. After the detection rod 4 extends into the hole, the ball 13 at its distal end contacts the hole wall. As Figure 2 shown, if the perpendicularity of the hole does not deviate, that is, the axis of the hole is vertically parallel to the hole wall, as the telescopic rod 3 extends into the hole, the inclination angle θ of the detection rod 4 will not change. As Figure 1 shown, if the perpendicularity of the hole deviates during the drilling process, the solid line represents the hole with deviation, and the dotted line represents the hole with no deviation in perpendicularity. After the perpendicularity deviates, the side wall of the hole will tilt. As the telescopic rod 3 extends, as Figure 3 shown, the inclination angle θ of the detection rod 4 will also change following the inclination state of the side wall. The angle sensor 5 can detect the change of the inclination angle θ of the detection rod 4 in real time. The distance sensor on the side of the mounting seat 11 can detect the actual distance L1 from the side of the mounting seat 11 to the hole wall in real time. This actual distance L1 also changes following the inclination state of the hole wall. If the hole tilts to the left, the value of L1 will become smaller and smaller. The half-length L2 of the mounting seat 11 can be known, and the length L3 of the detection rod 4 can be known. According to the inclination angle of the detection rod 4, the length of the mounting seat 11, and the actual distance, the inclination angle of the hole wall can be obtained, and then the specific perpendicularity of the hole can be obtained. Specifically: According to the inclination angle value θ of the detection rod 4, L3, and the trigonometric function relationship, the length C of one right-angled side and the length L of the other right-angled side can be obtained. L - L2 - L1 = L4, where L4 is the deviation distance between the inclined hole wall and the standard hole wall. Then, according to C and L4 and the trigonometric function relationship, the deviation angle β of the hole wall can be obtained. Again, according to the value of the deviation angle β and the trigonometric function relationship, the inclined length B of the hole wall can be obtained. One or more detection rods 4 can be provided. Finally, rotate the telescopic rod 3 to detect the perpendicularity deviation angle of one week of this section of the hole. The telescopic rod 3 extends towards the bottom of the hole section by section to obtain the deviation angle of each section of the hole and the length of each section of the detected hole. The three-dimensional space shape of the entire hole is fitted by combining the inclination angle values of multiple sections of the hole, so as to more intuitively see the change of the perpendicularity of the hole. The entire detection process does not require manual detection by relying on visual perception, and realizes automatic detection and calculation throughout the process. This device can more conveniently detect the perpendicularity deviation angle and deviation direction of the hole, and the structure of the detection device is simple.

[0023] Further, a spherical fixed sleeve 12 is provided at one end of the detection rod 4 adjacent to the hole wall, and the ball 13 is movably arranged in the fixed sleeve 12. As Figure 5As shown in the figure, specifically, the fixed sleeve 12 has a spherical cavity inside. The ball 13 is movably embedded in the spherical cavity. There is a hole in the spherical cavity, and about one-third of the ball 13 is exposed outside the fixed sleeve 12. The ball 13 improves the smoothness of the downward movement of the detection rod 4 along the hole wall and the smoothness of the rotation of the detection rod 4.

[0024] Further, the lowermost end of the telescopic rod 3 passes through the mounting seat 11. A bottom plate 8 is provided at the lower end of the telescopic rod 3 and is located on the bottom surface of the mounting seat 11. A driving assembly for driving the mounting seat 11 to squeeze the detection rod 4 inward is provided between the bottom plate 8 and the mounting seat 11.

[0025] Further, as Figure 4 shown, a notch groove 14 corresponding to the detection rod 4 is provided on the top surface of the mounting seat 11, and the bottom surface of the notch groove 14 is an inclined surface.

[0026] Further, the driving assembly includes a driving member 7 and a transmission block 10. The top surface of the transmission block 10 is in contact with the bottom surface of the mounting seat 11 in an inclined straight surface, and the bottom surface of the transmission block 10 is in contact with the flat straight surface of the bottom plate 8. The driving member 7 drives the transmission block 10 to move, and the movement of the transmission block 10 drives the position of the mounting seat 11 to change and squeezes the detection rod 4 inward.

[0027] Further, the top surface of the bottom plate 8 has a pelvic cavity 9, the driving member 7 is installed on the side wall of the pelvic cavity 9, and there are two transmission blocks 10, which are symmetrically arranged in the pelvic cavity 9.

[0028] Further, the driving member 7 is a cylinder or an electric cylinder, and the telescopic end of the driving member 7 passes through the side wall of the pelvic cavity 9 and is in contact with the side wall of the transmission block 10.

[0029] Specifically, as Figure 1 shown, after the perpendicularity detection of the hole is completed, the detection device needs to be recovered. At this time, the controller controls the driving member 7 to act. The driving member 7 is a cylinder or an electric cylinder. The action of the driving member 7 makes the two transmission blocks 10 approach each other. The bottom surfaces of the two transmission blocks 10 are in contact with the bottom surface of the mounting seat 11 in an inclined straight surface, so that the mounting seat 11 moves upward by a certain distance. The upward movement of the mounting seat 11 makes the detection rod 4 snap into the notch groove 14. The mounting seat 11 exerts a squeezing force on the detection rod 4 toward the telescopic rod 3 side, so that the detection rod 4 rotates toward the telescopic rod 3 side, causing the ball 13 to disengage from the hole wall, and the telescopic rod 3 retracts to complete the recovery of the detection device.

[0030] Further, the telescopic rod 3 is an electric telescopic rod 3 or a pneumatic telescopic rod 3.

[0031] Further, a rotary motor 2 for driving the telescopic rod 3 to rotate is provided on the top surface of the fixed seat 1.

[0032] A method for detecting the perpendicularity of a hole includes the following steps: S1: Install the telescopic rod 3 at the central position of the fixed seat 1, and place the detection rod 4 and the mounting seat 11 in the hole; S2: Fix the fixed seat 1 at the hole opening, and make the telescopic rod 3 coincide with the center of the hole opening; S3: The telescopic rod 3 extends into the hole section by section until it reaches the bottom of the hole. Each time it extends, the angle sensor 5 detects the change in the inclination angle of the detection rod 4, and the distance sensor 6 detects the actual distance from the side of the mounting seat 11 to the hole wall. Combine the actual distance, the inclination angle of the detection rod 4, and the length of the mounting seat 11 to obtain the inclination angle of the hole wall; S4: Obtain the actual length of the inclined section of the hole wall according to the inclination angle of the hole wall; S5: The rotary motor 2 drives the telescopic rod 3 to rotate to obtain the inclination data of one week of the inclined section of the hole wall. Combine the data of multiple inclined sections of the hole wall with the corresponding inclination angles to fit the three-dimensional space shape of the hole; S6: The telescopic rod 3 retracts to recycle the detection device.

[0033] In this embodiment, after the telescopic rod 3 extends into the hole, adjust the telescopic rod 3 to the central position of the hole opening, and then fix the fixed seat 1 on the ground with bolts. The telescopic rod 3 extends downward by a certain distance. The angle sensor 5 detects the change in the inclination angle of the detection rod 4, and the distance sensor 6 detects the actual distance from the side of the mounting seat 11 to the hole wall. According to the trigonometric function relationship, obtain the lengths of the two right-angled sides of the triangle formed with the detection rod 4 as the inclined plane. Then, combine the length of the mounting seat 11, the actual distance, and the length of one of the right-angled sides to obtain the offset distance of the hole wall. Combine the offset distance of the hole wall with the length of the other right-angled side to obtain the inclination angle of the hole wall. According to the trigonometric function, obtain the offset length of the hole wall. The rotary motor 2 drives the telescopic rod 3 to rotate to obtain the inclination data of one week of the inclined section of the hole wall. Combine the data of multiple inclined sections of the hole wall with the corresponding inclination angles to fit the three-dimensional space shape of the hole; Finally, the controller controls the driving member 7 to act. The action of the driving member 7 makes the two transmission blocks 10 approach each other. The bottom surfaces of the two transmission blocks 10 are in inclined plane contact with the bottom surface of the mounting seat 11, so that the mounting seat 11 moves upward by a certain distance. The upward movement of the mounting seat 11 causes the detection rod 4 to be stuck in the notch groove 14. The mounting seat 11 exerts a squeezing force on the detection rod 4 toward the telescopic rod 3 side, so that the detection rod 4 rotates toward the telescopic rod 3 side, causing the ball 13 to disengage from the hole wall. The telescopic rod 3 retracts to complete the recycling of the detection device.
