Description

Technical Field

[0001] This invention belongs to the field of pile hole diameter detection technology, specifically a pile hole diameter detection device for municipal building construction. Background Technology

[0002] During municipal building construction, pile holes are drilled in the ground. The diameter of the pile holes is measured using a pile hole diameter detection device. However, existing pile hole diameter detection devices require finding the center of a circle and lowering the device at that center for measurement. This method of centering is extremely cumbersome and cannot quickly and accurately measure the pile hole diameter. As a result, the pile hole diameter detection process is time-consuming and labor-intensive, which slows down the progress of municipal building construction to some extent. In addition, most existing pile hole diameter detection devices can only measure at the opening of the pile hole and cannot measure the various sections at the depth of the pile hole, making it difficult for construction personnel to control the diameter at the depth of the pile hole.

[0003] Therefore, a device for detecting the diameter of pile holes used in municipal building construction is proposed to solve the above problems. Summary of the Invention

[0014] Preferably, the system further includes a pile hole contour drawing mechanism, which is mounted on the hole diameter detection mechanism and the lifting mechanism. The pile hole contour drawing mechanism includes a storage box and a touch panel assembly. The touch panel assembly is mounted on the bottom of the fixed sleeve and located outside the drive motor.

A first inclined block is connected to the top of the mounting block. A second inclined block is connected to the fixed block and can abut against the inclined surface of the first inclined block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention, by setting up a movable wheel, a circular scale, and gear four, allows the electric push rod to retract rapidly during testing. Due to the restoring effect of the tension spring one, the movable wheel can quickly abut against the inner wall of the pile hole. At this time, the tension spring one has not fully released its elastic force. Due to the operation of the drive motor, the movable wheel can roll along the hole wall. Under the rolling action of the movable wheel, the movable shaft and gear one can rotate. Due to the rotation of gear one, gear five, gear two, circular shaft one, gear three, and the circular scale can be meshed and rotated. Due to the rotation of gear three... Rotation drives gear four, shaft two, and the measuring disc to rotate. The circular measuring disc displays the travel length of the movable wheel, while the measuring disc displays the number of rotations of the circular measuring disc. After the movable wheel has rolled one revolution on the hole wall, the number of revolutions is observed through pointer two, and the value on the circular measuring disc is observed through pointer one. Finally, the circumference of the hole wall at that cross-section is obtained, and the hole diameter is determined from the circumference of the hole wall. This design can improve the accuracy of hole diameter measurement, allowing for inspection without finding the center of the circle, thereby improving the efficiency of pile hole diameter inspection.

[0017] This invention, by setting up a sliding shaft frame, a slider, and a fixing sleeve, places the support on the pile hole, roughly in the center of the pile hole. A motor drives a lead screw to rotate, which in turn drives the slider, fixing sleeve, hole diameter detection mechanism, pile hole contour drawing mechanism, and clay treatment mechanism to descend along the sliding shaft frame and penetrate into the pile hole. The device is lowered to the section of the pile hole that needs to be measured, so that the hole diameter detection mechanism and the pile hole contour drawing mechanism can detect the section of the pile hole at that point. This allows for the detection of hole diameters at different sections deep within the pile hole, thus expanding the application range of the device.

[0018] This invention, by setting up a touch panel assembly and a capacitive stylus, allows the movable wheel to contact the hole wall when the electric push rod rapidly retracts, causing the mounting block to move. This allows the inclined block one to gradually detach from the inclined block two. At this time, the tension spring two, under tension, can lift the lifting frame, mounting plate, and capacitive stylus due to the restoring effect of its elasticity. This causes the capacitive stylus to extend from inside the storage box and contact the receiving surface of the touch panel assembly. As the movable wheel rolls, the capacitive stylus synchronously draws the rolling trajectory of the movable wheel on the touch panel assembly. When encountering a protrusion or depression in the hole wall, the mounting block moves along with the movable wheel, drawing the protrusion or depression of the hole wall during the process of the capacitive stylus drawing its trajectory. Construction personnel can observe the trajectory and changes of the hole wall in real time at an external image receiving end, thereby determining the hole diameter of the cross-section and obtaining the position and size of the protrusions and depressions in the cross-section hole wall.

[0019] This invention, by setting up a pressing wheel and a scraper, allows clay from the hole wall to easily adhere to the movable wheel during its rolling process. The tension spring three, under tension, due to its restoring elasticity, can drive the pressing wheel to tightly abut against the movable wheel via the limiting frame and fixing frame. Under the pressing and abutting action between the movable wheel and the pressing wheel, the clay on the movable wheel is squeezed out by the pressing wheel. If harder, more stubborn clay adheres to the movable wheel, it will cause the pressing wheel, fixing frame, limiting frame, and rack one to move outwards as it passes through the pressing wheel, further stretching the tension spring three. Simultaneously, rack one, through gear six, drives rack two to move within the connecting block. As rack two moves, fixed shaft one and fixed arm move together, and fixed shaft two drives the arc block and scraper to retract into the arc sleeve. At this time, the arc spring is compressed. After the stubborn clay has completely passed through the extrusion wheel, due to the disappearance of the extrusion force between the extrusion wheel and the stubborn clay, and due to the restoring effect of the elastic force of tension spring three and the arc spring, the extrusion wheel can continue to press against the movable wheel. At the same time, the arc block and scraper will quickly pop out from the arc sleeve. The scraper scrapes off the stubborn clay on the movable wheel, thereby removing the clay adhering to the surface of the movable wheel during the detection process. This can prevent the clay from affecting the final measurement value and improve the accuracy of the device. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 13 As shown, the present invention provides a pile hole diameter detection device for municipal building construction, including a lifting mechanism 1 and a hole diameter detection mechanism 2;

[0036] The aperture detection mechanism 2 is mounted on the lifting mechanism 1;

[0037] The aperture detection mechanism 2 includes a drive motor 21, which is mounted on the lifting mechanism 1. The drive motor 21 drives and connects to a fixed block 22. A slide rod 23 is movably sleeved inside the fixed block 22. One end of the slide rod 23 is connected to a connecting plate 24, and the other end is connected to a mounting block 26. A connecting rod 27 is connected to the other side of the mounting block 26, and the other end of the connecting rod 27 is connected to a connecting block 28. A tension spring 25 located outside the slide rod 23 connects the connecting plate 24 and the fixed block 22. An electric push rod 223 is mounted on the fixed block 22, and the output end of the electric push rod 223 abuts against the connecting plate 24. A movable shaft 29 is movably mounted inside the connecting block 28, and a fixed sleeve is attached to the outside of the movable shaft 29. The movable wheel 210 inside, the movable shaft 29 is externally fixedly fitted with a gear 211, the connecting block 28 is movably mounted on both sides with a first round shaft 212 and a second round shaft 216 respectively, the outer side of the first round shaft 212 is fixedly fitted with a round wheel ruler 213, the outer side of the first round shaft 212 is fixedly fitted with a gear 215 located above the round wheel ruler 213, the outer side of the first round shaft 212 is fixedly fitted with a gear 214 located above the gear 215, the outer side of the round wheel ruler 213 is provided with measuring scale, the outer side of the second round shaft 216 is fixedly fitted with a gear 217, the gear 217 meshes with the gear 215, the outer side of the second round shaft 216 is fixedly fitted with a ruler 218 located above the gear 217, the ruler 218 is provided with a circle number scale.

[0038] Using the above scheme: During testing, the electric push rod 223 retracts rapidly. Due to the restoring effect of the spring 25, the movable wheel 210 can be quickly driven to abut against the inner wall of the pile hole. At this time, the spring 25 has not fully released its elastic force. Due to the operation of the drive motor 21, the movable wheel 210 can be driven to roll along the hole wall. Under the rolling action of the movable wheel 210, the movable shaft 29 and gear 211 can be rotated. Due to the rotation of gear 211, gears 224, 214, 212, 215, and 213 can be meshed and driven to rotate. The rotation of gear 3 215 drives gear 4 217, shaft 2 216 and scale 218 to rotate. The travel length of the movable wheel 210 is displayed by the scale 213, and the number of rotations of the scale 213 is displayed by the scale 218. After the movable wheel 210 rolls once on the hole wall, the number of rotations is observed by pointer 222 and the value on the scale 213 is observed by pointer 1 221. Finally, the circumference of the hole wall at that cross section is obtained. The specific value of the hole diameter is obtained by the circumference of the hole wall, which can improve the accuracy of hole diameter measurement and allow for detection without finding the center.

[0039] like Figure 3 and Figure 4As shown, the lifting mechanism 1 includes a bracket 11, a sliding shaft frame 12 is installed inside the bracket 11, a slider 13 is slidably sleeved on the outside of the sliding shaft frame 12, a fixed sleeve 14 is connected to the bottom of the slider 13, a lead screw 15 that can be driven by a motor is threaded inside the slider 13, and the bottom end of the fixed sleeve 14 is connected to the drive motor 21.

[0040] Using the above scheme: the support 11 is assumed to be on the pile hole, so that it is roughly in the center of the pile hole. The motor drives the lead screw 15 to rotate. Under the action of the lead screw, the slider 13, the fixed sleeve 14, the hole diameter detection mechanism 2, the pile hole outline drawing mechanism 3 and the clay treatment mechanism 4 are driven to descend along the sliding frame 12 and penetrate into the pile hole. They are lowered to the pile hole section that needs to be measured, so that the hole diameter detection mechanism 2 and the pile hole outline drawing mechanism 3 can be used to detect the section of the pile hole at that point.

[0041] like Figure 6 , Figures 9 to 11 As shown, a housing 220 is connected above the connecting block 28 and located outside the scale plate 218, gear 214, and gear 211. The top end of the round shaft 216 extends to the top of the housing 220 and is fixedly fitted with a knob 219. A pointer 222 that can indicate the scale on the scale plate 218 is connected above the housing 220. A pointer 221 that can indicate the scale on the circular wheel scale 213 is connected to the housing 220. A gear 5 224 that can mesh with gear 214 and gear 211 is movably installed inside the housing 220. Gear 214, gear 5 224, and gear 211 have the same size. The circular wheel scale 213 and the movable wheel 210 have the same diameter.

[0042] Using the above scheme: Since gears 214, 524, and 111 are the same size, their angular velocities and linear velocities are the same. Furthermore, since gear 1211 and the movable wheel 210 have the same angular velocity, their angular velocities are also the same. Since the diameters of the circular ruler 213 and the movable wheel 210 are the same, their linear velocities are also the same. Therefore, the circular ruler 213 displays the travel distance of the movable wheel 210. Simultaneously, for every one rotation of the circular ruler 213, the scale plate 218 rotates one mark, allowing the scale plate 218 to display the number of rotations of the circular ruler 213.

[0043] like Figure 6 , Figure 12 and Figure 13As shown, it also includes a clay treatment mechanism 4, which is set inside the aperture detection mechanism 2. The clay treatment mechanism 4 includes a limiting frame 41, which is movably sleeved inside the connecting block 28. A fixing frame 45 outside the connecting block 28 is connected to one side of the limiting frame 41. A pressing wheel 47 that abuts against the movable wheel 210 is movably installed inside the fixing frame 45. A tension spring 46 located outside the limiting frame 41 is connected between the connecting block 28 and the fixing frame 45.

[0044] Using the above solution: During the rolling process of the movable wheel 210, clay from the hole wall easily sticks to the movable wheel 210. The tension spring 46, which is in a stretched state, can drive the extrusion wheel 47 to tightly abut against the movable wheel 210 through the limit frame 41 and the fixed frame 45 due to the recovery effect of the elasticity. Under the extrusion and abutment action between the movable wheel 210 and the extrusion wheel 47, the clay on the movable wheel 210 can be squeezed by the extrusion wheel 47 and detached from the movable wheel 210.

[0045] like Figure 6 , Figure 12 and Figure 13 As shown, a gear six 42 is movably installed inside the connecting block 28, and a rack one 43 extending into the inside of the connecting block 28 is connected to the inner side of the limiting bracket 41. The rack one 43 meshes with the gear six 42, and a rack two 44 that can mesh with the gear six 42 is slidably installed inside the connecting block 28.

[0046] Using the above scheme: if hard, stubborn clay adheres to the movable wheel 210, when it passes through the extrusion wheel 47, it will cause the extrusion wheel 47, the fixed frame 45, the limit frame 41 and the rack 43 to move outward, thereby further stretching the tension spring 46. At the same time, the rack 43 drives the rack 44 to move within the connecting block 28 through the meshing of the gear 42.

[0047] like Figure 6 , Figure 12 and Figure 13 As shown, an arc sleeve 48 is installed inside the connecting block 28, and an arc block 49 is movably fitted inside the arc sleeve 48. A scraper 410 that can abut against the movable wheel 210 is connected to one side of the arc block 49, and an arc spring 411 is connected to the other side of the arc block 49. The other end of the arc spring 411 is connected to the inner wall of the arc sleeve 48.

[0048] Using the above solution: when the arc spring 411 is compressed, due to the elastic recovery effect of the arc spring 411, the arc block 49 and the scraper 410 can be quickly ejected from the arc sleeve 48, and the stubborn clay on the movable wheel 210 can be scraped off by the scraper 410.

[0049] like Figure 6 , Figure 12 and Figure 13As shown, the bottom of the arc block 49 is connected to a fixed shaft 413 extending below the connecting block 28, and the bottom of the rack 44 is connected to a fixed shaft 412 extending below the connecting block 28. A fixed arm 414 is fixedly sleeved on the outside of the fixed shaft 412, and the fixed shaft 413 can move within the fixed arm 414.

[0050] Using the above scheme: Due to the movement of rack 2 44, fixed shaft 1 412 and fixed arm 414 can move together, and through fixed shaft 2 413, arc block 49 and scraper 410 are driven to retract into arc sleeve 48, so that arc spring 411 is compressed and stores force.

[0051] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, it also includes a pile hole contour drawing mechanism 3, which is set on the hole diameter detection mechanism 2 and the lifting mechanism 1. The pile hole contour drawing mechanism 3 includes a storage box 31 and a touch panel assembly 32. The touch panel assembly 32 is installed at the bottom of the fixed sleeve 14 and is located outside the drive motor 21. The storage box 31 is installed above the mounting block 26. A lifting frame 33 is slidably mounted inside the mounting block 26. The top of the lifting frame 33 extends into the storage box 31 and is connected to a mounting plate 35. A capacitive pen 36 is installed inside the mounting plate 35. A tension spring 2 34 is connected to the bottom of the mounting block 26. The other end of the tension spring 2 34 is connected to the lifting frame 33. A ramp block 1 37 is connected to the top of the mounting block 26. A ramp block 2 38 that can abut against the ramp block 1 37 is connected to the fixed block 22.

[0052] Using the above scheme: When the electric push rod 223 retracts rapidly and the movable wheel 210 abuts against the hole wall, the movement of the mounting block 26 allows the inclined block 37 to gradually detach from the inclined block 38. At this time, the tension spring 34, which is in a stretched state, can drive the lifting frame 33, the mounting plate 35, and the capacitive pen 36 to rise due to the recovery effect of the elasticity. This allows the capacitive pen 36 to extend from the inside of the storage box 31 and abut against the receiving surface of the touch panel assembly 32. When the movable wheel 210 rolls, the capacitive pen 36 will simultaneously draw the rolling trajectory of the movable wheel 210 on the touch panel assembly 32. When encountering a protrusion or depression in the hole wall, the mounting block 26 will move along with the movable wheel 210. During the process of the capacitive pen 36 drawing the trajectory, the protrusion or depression of the hole wall will be drawn simultaneously.

[0053] Working principle and usage process of this invention:

[0054] The support 11 is placed on the pile hole, roughly in the center of the pile hole. The motor drives the lead screw 15 to rotate. Under the action of the lead screw, the slider 13, the fixed sleeve 14, the hole diameter detection mechanism 2, the pile hole outline drawing mechanism 3 and the clay treatment mechanism 4 are driven to descend along the sliding frame 12 and penetrate into the pile hole. They are lowered to the section of the pile hole that needs to be measured, so that the section of the pile hole can be detected by the hole diameter detection mechanism 2 and the pile hole outline drawing mechanism 3.

[0055] During testing, the electric push rod 223 retracts rapidly, causing the connecting plate 24 to lose its support. The tension spring 25, currently under tension, quickly moves the connecting plate 24, slide rod 23, mounting block 26, connecting rod 27, and connecting block 28 due to its restoring elasticity, causing the movable wheel 210 to abut against the inner wall of the pile hole. At this time, the tension spring 25 has not fully released its elasticity. Due to the operation of the drive motor 21, the movable wheel 210 can roll along the hole wall, and simultaneously, under the restoring elasticity of the tension spring 25... The tension spring 25 can slide laterally within the fixed block 22 according to the protrusions or depressions of the hole wall, ensuring that the movable wheel 210 always abuts against the hole wall. The rolling action of the movable wheel 210 causes the movable shaft 29 and gear 211 to rotate. The rotation of gear 211 meshes with and drives gears 224, 214, 212, 215, and 213 to rotate. The rotation of gear 215, in turn, drives gear 217, 216, and 218 to rotate. Since gears 214, 524, and 111 are the same size, their angular velocities and linear velocities are also the same. Furthermore, because gear 1211 and the movable wheel 210 have the same angular velocity, their angular velocities are also the same. Since the diameters of the circular scale 213 and the movable wheel 210 are the same, their linear velocities are also the same. Therefore, the circular scale 213 can be used to display the movement of the movable wheel. The travel length of the moving wheel 210 is measured while the circular ruler 213 rotates one revolution. The scale 218 will rotate one mark, and the number of revolutions of the circular ruler 213 can be displayed on the scale 218. After the moving wheel 210 rolls one revolution on the hole wall, the number of revolutions is observed through pointer two 222, and the value on the circular ruler 213 is observed through pointer one 221. The calculation is: number of revolutions × maximum value of the scale on the circular ruler 213 + the current value of the scale on the circular ruler 213 = the circumference of the hole wall at this cross section. Finally, the specific value of the hole diameter is obtained by using the circumference of the hole wall.

[0056] When the electric push rod 223 retracts rapidly, causing the movable wheel 210 to abut against the hole wall, the movement of the mounting block 26 allows the inclined block 37 to gradually detach from the inclined block 38. At this time, the tension spring 34, which is in a stretched state, can drive the lifting frame 33, the mounting plate 35, and the capacitive pen 36 to rise due to the restoring effect of the elasticity. This causes the capacitive pen 36 to extend from the inside of the storage box 31 and abut against the receiving surface of the touch panel assembly 32. As the movable wheel 210 rolls, the capacitive pen 36 will synchronously draw the rolling trajectory of the movable wheel 210 on the touch panel assembly 32. When encountering a protrusion or depression in the hole wall, the mounting block 26 will move along with the movable wheel 210. During the process of the capacitive pen 36 drawing the trajectory, the protrusion or depression of the hole wall is drawn. Construction personnel can observe the trajectory and changes of the hole wall in real time at the external image receiving end, thereby determining the hole diameter of that section.

[0057] During the rolling of the movable wheel 210, clay from the hole wall easily sticks to it. The tension spring 46, under tension, due to its restoring elasticity, can drive the compression wheel 47 to tightly abut against the movable wheel 210 via the limit bracket 41 and the fixed bracket 45. Under the compression and abutment action between the movable wheel 210 and the compression wheel 47, the clay on the movable wheel 210 is squeezed and removed from it. If hard, stubborn clay sticks to the movable wheel 210, when it passes the compression wheel 47, the compression wheel 47, fixed bracket 45, limit bracket 41, and rack 43 will move outwards, further stretching the tension spring 46. Simultaneously, rack 43, through gear 6 42, drives rack 2 44 within the connecting block 28. The movement of rack 24 allows fixed shaft 1 412 and fixed arm 414 to move together, and through fixed shaft 2 413, arc block 49 and scraper 410 are driven to retract into arc sleeve 48. At this time, arc spring 411 is compressed. After the stubborn clay has completely passed through extrusion wheel 47, due to the disappearance of the extrusion pressure between extrusion wheel 47 and stubborn clay, and due to the elasticity recovery effect of tension spring 3 46 and arc spring 411, extrusion wheel 47 can continue to abut against movable wheel 210. At the same time, arc block 49 and scraper 410 will quickly pop out from arc sleeve 48. The scraper 410 scrapes off the stubborn clay on movable wheel 210, thereby removing the clay adhering to the surface of movable wheel 210 during the detection process and preventing the clay from affecting the final measurement value.
