Description

Technical Field

[0001] This application relates to the field of pile hole detection technology, and in particular to a hole and trenching detection device under dry hole conditions. Background Technology

[0002] Currently, in the fields of bridges, high-rise buildings and other construction projects, the most widely used foundation form and support structure is the use of hole-forming and trench-casting to form pile foundations. The quality of hole-forming directly affects the quality of pile formation, thus affecting the quality and safety of the entire project.

[0003] Before the pile foundation is poured, the quality of the borehole needs to be inspected to ensure the quality of the piles and the entire project. A common method for inspecting the borehole quality involves placing spliced ​​steel plates on a casing, with a gap in the middle for lowering a probe. The inspection equipment is placed on the steel plate, and the probe is lowered through the gap to inspect the borehole and trench. In this process, the spliced ​​steel plates support the weight of the entire inspection equipment, and the equipment needs to be manually moved onto the plates, posing a significant safety hazard.

[0004] Therefore, how to conduct hole and trenching inspection under dry hole conditions while ensuring safety has become an urgent problem to be solved in this field. Utility Model Content

[0005] In order to perform hole and trenching inspection under dry hole conditions with safety considerations, this application provides a hole and trenching inspection device under dry hole conditions.

[0006] The technical solution of the hole and trenching inspection equipment under dry hole conditions provided in this application is as follows: A hole-forming and grooving inspection device under dry hole conditions includes a telescopic support, a winch, a stranded wire, and a probe; the telescopic support is installed above the casing; the winch is installed on one side of the telescopic support, and a reel is provided inside the winch; the stranded wire is wound on the reel, and one end of the stranded wire is connected to the probe; the stranded wire passes through the telescopic support, allowing the probe to enter the casing.

[0007] By adopting the above technical solution, a telescopic support is installed above the casing, and the stranded wire binding the probe passes through the telescopic support. A winch is installed next to the telescopic support, and a reel is installed inside the winch. The stranded wire is wound onto the reel. When testing is required, the reel is rotated to lengthen the stranded wire, thereby lowering the probe. When testing is finished, the reel rotates to rewind the stranded wire back onto the reel, thereby retracting the probe. One end of the stranded wire is fixedly connected to the probe, and the other end is wound onto the reel. When using the testing equipment to test grooves and holes, it is only necessary to install the telescopic support above the casing and the winch next to the telescopic support. The telescopic support provides some support to the stranded wire, allowing the stranded wire and probe to be lowered vertically. It is not necessary to move the winch above the casing for testing, which increases safety and eliminates the safety hazards caused by the steel plate on which the testing equipment is placed tipping over or breaking during testing.

[0008] Preferably, there are multiple spools, which are placed side by side.

[0009] By adopting the above technical solution, multiple spools are placed side by side, with the shafts of the multiple spools located on the same straight line. This increases the service life of the multiple spools and prevents individual spools from wearing out too quickly and requiring frequent replacement.

[0010] Preferably, there are multiple strands of wire, and the number of strands is the same as the number of spools.

[0011] By adopting the above technical solution, multiple strands are wound on different reels, and all the strands are connected to the probe. The multiple strands can not only ensure the balance of the probe when it is lowered for testing, but also provide a certain degree of protection for the probe, preventing the strands from breaking during testing and causing the probe to fall and damage the probe or the hole.

[0012] Preferably, the winch further includes a transmission device, pressure sensors, pedometers, and a second drive unit. The transmission device is fixed to the side of the winch near the telescopic support. There are multiple pressure sensors, the number of which is the same as the number of reels, and all of the pressure sensors are fixed to the transmission device. There are multiple pedometers, the number of which is the same as the number of reels, and each of the multiple pedometers is fixed to a pressure sensor. The stranded wire is wound around the pedometer. The output end of the second drive unit is connected to the transmission device.

[0013] By adopting the above technical solution, the stranded wire is wound around the pedometer, and a pressure sensor is installed under the pedometer. When the probe is lowered normally, the stranded wire directly presses on the sliding wheel of the pedometer, applying a downward pressure to the pedometer. The force on the pedometer is relatively uniform. When the probe connected to the stranded wire touches the bottom of the hole during detection, the pressure on the pedometer will change abruptly. The pressure sensor detects the change in force, and the depth of the hole is calculated by the pedometer. The second driving component drives the transmission device. The pedometer and the pressure sensor are both installed on the transmission device. When the spool reverses and retracts the stranded wire, the driving component is activated to drive the transmission device. The transmission device drives the pedometer to move left and right within a certain range, so that the stranded wire is evenly wound on the spool, preventing uneven winding on the spool due to single-point winding and the occurrence of wire detachment. Preferably, the pedometer includes multiple sliding wheels that collectively constrain the stranded wire.

[0014] By adopting the above technical solution, the stranded wire is directly pressed onto the sliding surface, applying a certain pressure to the sliding wheel. The sliding wheel can rotate around its axis. When the wire is released from the wheel, the sliding wheel provides certain support for the stranded wire, restricting the stranded wire and preventing it from vibrating during release, which could lead to inaccurate test results or even damage to the probe.

[0015] Preferably, the telescopic support includes connecting rods, legs, and round tubes. The connecting rods include multiple first connecting rods and multiple second connecting rods, which are hinged to each other. There are multiple legs, which are respectively installed around the telescopic support to hold the protective sleeve, and the legs are telescopic. There are multiple round tubes, and both ends of the multiple round tubes are respectively connected to different connecting rods. All the multiple round tubes can rotate around an axis, and the axis of the round tube is parallel to the axis of the parallel-placed reels. The stranded wire is laid on the round tube.

[0016] By adopting the above technical solution and utilizing the principle of a quadrilateral telescopic mechanism, multiple connecting rods are set up. Multiple first connecting rods and multiple second connecting rods are hinged to each other to form a quadrilateral structure, which can be telescopic, thus ensuring that the telescopic support is suitable for protective cylinders of various sizes. The support feet clamp the protective cylinder, and the telescopic support feet can be freely adjusted in height to suit protective cylinders of different heights. Multiple round tubes are set up, with different connectors at both ends of the round tubes. The axis of the round tubes is parallel to the axis of the parallel reels, so that the stranded wire wound on the reels can be laid on the round tubes. During testing, the round tubes are used to extend the stranded wire from the reels to the telescopic support, so that the stranded wire turns downward from the round tubes it is laid on. The round tubes can rotate around their axes, making the wire release from the reels smoother.

[0017] Preferably, the telescopic bracket further includes a locking element; the locking element is fixedly connected to the connecting rod.

[0018] By adopting the above technical solution, when the telescopic bracket extends to a suitable length using a quadrilateral structure, the connecting rod adjacent to the support leg is fixed by a locking device to prevent it from moving, thus fixing the entire telescopic mechanism.

[0019] Preferably, the winch further includes an operation panel and a first drive unit. The operation panel is fixed to the side of the winch away from the pedometer and includes multiple operation buttons. The first drive unit is electrically connected to the operation panel, and the output end of the first drive unit is connected to the shaft of the reel.

[0020] By adopting the above technical solution, the output end of the first driving component is connected to the shaft of the spool. The operation panel is used to control the first driving component to start, stop, or rotate forward and backward, thereby controlling the rotation direction of the spool and thus controlling the release or retraction of the stranded wire. At the same time, the operation panel is fixed on the side away from the pedometer, which is convenient for operation and will not affect the release and retraction of the stranded wire.

[0021] Preferably, the probe includes multiple laser rangefinders, which are mounted around the probe. By adopting the above technical solution, the number of laser rangefinders is equal to or greater than four, and multiple laser rangefinders are installed around the probe. The laser rangefinders are used to detect the hole wall spacing in the horizontal direction of the hole. The laser rangefinders have higher stability and reliability, and the measurement accuracy is relatively high.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The stranded wire passes through the telescopic support, which provides a certain load for the stranded wire. During testing, the installed telescopic support is directly moved onto the casing, and testing can be carried out without moving the winch. Under the premise of safety, hole and groove testing is carried out under dry hole conditions.

[0023] 2. The connecting rods on the telescopic support are hinged to each other to form a quadrilateral telescopic structure, which allows the telescopic support to adjust the telescopic length, thereby adapting to different sizes of protective cylinders and making it widely applicable.

[0024] 3. A pressure sensor is installed under the pedometer to detect the component force applied to the pedometer by the stranded wire in real time. When the probe is lowered, the pressure sensor detects a uniform force. When the probe touches the bottom, the component force applied to the pedometer by the stranded wire changes abruptly. The pressure sensor detects the force change, and the pedometer is used to detect the hole depth.

[0025] 4. Multiple laser rangefinders for horizontal measurement are installed around the probe. The laser rangefinders have high reliability and stability, and also have high detection accuracy. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a hole-forming and trenching detection device under dry hole conditions.

[0030] Example 1 Reference Figure 1The hole-forming and trenching detection equipment under dry hole conditions includes a telescopic support 1, a winch 2, a stranded wire 3, and a probe 4; the telescopic support 1 is installed above the casing 10; the winch 2 is installed on one side of the telescopic support 1, and a reel 21 is provided inside the winch 2; the stranded wire 3 is wound on the reel 21, and one end of the stranded wire 3 is connected to the probe 4; the stranded wire 3 passes through the telescopic support 1, so that the probe 4 enters the casing 10. The telescopic bracket 1 is installed on the protective casing 10. One end of the stranded wire 3 is wound around the reel 21, and the other end is fixed to the probe 4. The stranded wire 3 passes through the telescopic bracket 1 and rests on the round tube 13. The round tube 13 provides a certain support for the stranded wire 3. The winch 2 is placed on one side of the telescopic bracket 1. The position of the stranded wire 3 is changed by using the telescopic bracket 1. The position of the probe 4 is also different when the stranded wire 3 rests on different round tubes 13. However, it is necessary to ensure that the probe 4 is located in the protective casing 10. It is not necessary to place the splicing steel plate on the protective casing 10 and then place the winch 2 on the steel plate. This greatly improves the safety during the test and also ensures the accuracy of the test.

[0031] There are multiple reels 21, which are placed side by side. In this embodiment, there are two reels 21. The reels 21 are installed on the winch 2 away from the pedometer 24. The axes of the multiple reels 21 coincide and can all rotate around the axis. In this embodiment, the rotation direction of the reel 21 when releasing the strand 3 is set to forward rotation, and the rotation direction of the reel 21 when retracting the strand 3 is set to reverse rotation. The operation panel 25 can control the forward or reverse rotation of the reel 21 by controlling the first drive component 26. At the same time, the rotation speed of the multiple reels 21 should be consistent. The multiple reels 21 can be installed on the same shaft, and the same shaft can be used to control the rotation speed of all reels 21 to be consistent. This ensures that when the probe 4 is lowered, the tension of the strand fixed on the probe 4 is consistent, and the probe 4 will not be subjected to uneven tension due to inconsistent tension, which would result in unsatisfactory detection results.

[0032] The stranded wires 3 are multiple, and the number of stranded wires 3 is the same as the number of spools 21. The multiple stranded wires 3 are wound on different spools 21 respectively, and the multiple stranded wires 3 are evenly fixed on the probe 4. In this embodiment, there are two stranded wires 3, which are fixed on the symmetrical sides of the probe 4 respectively, to ensure that the probe 4 is subjected to equal tension from the stranded wires 3, thereby ensuring that the probe 4 will not tilt during detection and ensuring the accuracy of detection. In this embodiment, the stranded wires 3 should be made of high-strength, wear-resistant materials and have a certain resistance to tearing.

[0033] The winch 2 also includes a transmission device 22, pressure sensors 23, pedometers 24, and a second drive unit 27. The transmission device 22 is fixed to the side of the winch 2 near the telescopic support 1. There are multiple pressure sensors 23, the number of which is the same as the number of reels 21, and all of the multiple pressure sensors 23 are fixed to the transmission device 22. There are multiple pedometers 24, the number of which is the same as the number of reels 21, and each of the multiple pedometers 24 is fixed to a corresponding pressure sensor 23. The stranded wire 3 is wound around the pedometer 24. The output end of the second drive unit 27 is connected to the transmission device 22. In this embodiment, there are two pressure sensors 23 and two pedometers 24. The transmission device 22 is a lead screw drive, and the second drive component 27 is a motor. The second drive component 27 controls the transmission device 22 to rotate forward or backward, thereby controlling the pressure sensor 23 to move left or right. However, the range of movement of the pressure sensor 23 should be less than or equal to the length of the spool 211 on a single spool 21. The stranded wire 3 is pressed on the pedometer 24. The pedometer 24 provides certain support to the stranded wire 3 and can also prevent the stranded wire 3 from vibrating when it is unwinding. At the same time, it can provide a detection source for the pressure sensor 23.

[0034] In this embodiment, a limiting member 101 is provided on the telescopic bracket 1 near the pedometer 24. The limiting member 101 is fixed on the telescopic bracket 1, and the stranded wire 3 passes through the limiting member 101. When retracting or releasing the wire, the pedometer 24 needs to move together with the pressure sensor 23 under the action of the transmission device 22 so that the stranded wire 3 can be evenly released or retracted from the reel 21. In this case, the stranded wire 3 will also move left and right with the pedometer 24. If the stranded wire 3 is not limited, the probe 4 may also move left and right under the pull of the stranded wire 3. Therefore, a limiting member 101 is needed to limit the part of the stranded wire 3 from the limiting member 101 to the probe 4 so that this part of the stranded wire 3 will not move with the pedometer 24, thereby ensuring that the probe 4 is not affected.

[0035] In other embodiments of this application, since the inner edge of the telescopic bracket 1 near the round tube of the limiting member 101 contacts the stranded wire 3, the outer edge of the stranded wire 3 will be scraped when it is retracted or released. Therefore, the edge of the telescopic bracket 1 that contacts the stranded wire 3 can be rounded, or an anti-wear strip can be installed on the rod of the telescopic bracket 1, or other technical means known to those skilled in the art can be used to protect the stranded wire 3. The pedometer 24 includes multiple sliding wheels 241, which together constrain the stranded wire 3. In this embodiment, there are two sliding wheels 241 of different sizes. The stranded wire 3 passes over the larger sliding wheel 2411 and then changes direction, passing over the smaller sliding wheel 2412. Both sliding wheels 241 provide support for the stranded wire 3. The side plates of both sliding wheels 241 are relatively high, which can restrict the position of the stranded wire, ensuring that the stranded wire remains on the sliding wheel 241. When the control wheel 21 releases the wire, the sliding wheel 241 rotates synchronously with the release of the stranded wire 3. The length of the released stranded wire is calculated by counting the number of rotations of the sliding wheel 241. In this embodiment, the height of the telescopic bracket 1 should be lower than the height of the pedometer 24. When the stranded wire 3 is connected below the probe, it ensures that the stranded wire 3 can fully contact the sliding wheel 241, preventing insufficient force between the stranded wire 3 and the sliding wheel 241, which could lead to inaccurate test results.

[0036] The telescopic support 1 includes connecting rods 11, legs 12, and circular tubes 13. The connecting rods 11 include multiple first connecting rods 111 and multiple second connecting rods 112, which are hinged together. Multiple legs 12 are installed around the telescopic support 1 to hold the protective sleeve 10; the legs 12 are telescopic. Multiple circular tubes 13 are present, with each end connected to a different connecting rod 11. All circular tubes 13 can rotate around an axis, and the axes of all circular tubes 13 are parallel to the axes of the parallel-placed reels 21. The stranded wire 3 rests on the circular tubes 13. In this example, the principle of a quadrilateral telescopic mechanism is used to hinge multiple first connecting rods 111 and multiple second connecting rods 112 to form multiple... The quadrilateral telescopic mechanism consists of multiple quadrilateral telescopic mechanisms forming a row of telescopic mechanisms, with a total of two rows of telescopic mechanisms. The two ends of the circular tube 13 are respectively connected to the two rows of telescopic mechanisms, and the axis of the circular tube 13 should be horizontal. In this embodiment, there are four legs 12, and the four legs 12 fix the two rows of telescopic mechanisms respectively. When the telescopic bracket 1 is installed on the protective cylinder 10, the protective cylinder 10 is clamped by the legs 12. When installing the telescopic bracket 1, the legs 12 need to be fixed. The fixing method can be to fix the legs 12 to the ground with screws, or to add counterweights to the legs 12 to press the entire legs 12 to prevent movement, or any other fixing method that does not affect the detection. The telescopic length of the telescopic bracket 1 is adjustable to adapt to protective cylinders 10 of different sizes, and the legs 12 can also be telescopic to adapt to protective cylinders 10 of different heights.

[0037] The telescopic bracket 1 also includes a locking member 14; the locking member 14 is fixedly connected to the connecting rod 11; the locking member 14 is used to fix the connecting rod 11. When the telescopic bracket 1 is adjusted to a suitable length, the locking member 14 is used to lock the connecting rod 11, thereby restricting the telescopic bracket 1 from extending or retracting due to the tension of the twisted wire 3 and the probe 4, which would cause the round tube 13 to move and affect the test results. When fixing the connecting rod 11, a shim can be installed in the hole of the locking member to restrict the movement of the connecting rod 11, or a limiting rod at different positions can be set to restrict the space of the connecting rod 11, or any other method that does not affect the test can be used; when the support leg 12 is fixed, the extension and retraction of the telescopic bracket 1 is already restricted to a certain extent, and the locking member 14 further restricts the movement of the connecting rod 11, further restricting the connecting rod 11. The winch 2 also includes an operation panel 25 and a first drive unit 26. The operation panel 25 is fixed to the side of the winch 2 away from the pedometer 24. The operation panel 25 includes multiple operation buttons 251. The first drive unit 26 is electrically connected to the operation panel 25, and the output end of the first drive unit 26 is connected to the shaft of the reel 21. The operation panel 25 is used to control the first drive unit 26, which is connected to the reel 21. The first drive unit 26 can be controlled to rotate or stop, rotate forward or reverse, by different operation buttons 251, thereby controlling the reel 21 to rotate or stop, rotate forward or reverse. At the same time, the operation panel 25 should be installed on the side away from the pedometer 24, that is, away from the telescopic bracket 1, so that the operation is more convenient and avoids contact with the stranded wire 3 during operation.

[0038] The probe 4 includes multiple laser rangefinders 41, which are installed around the probe 4. Compared with ultrasonic testing technology, laser ranging technology has higher stability, reliability and accuracy. When the hole wall is honeycomb-shaped, such as the protective sleeve 10 with solidified concrete blocks on the surface, the ultrasonic signal will be severely attenuated, making it impossible for the device to receive an effective reflected signal. However, laser ranging technology does not have this problem. Laser ranging technology emits an infrared laser with a fixed frequency and speed to the hole wall, uses a receiver to receive the light signal reflected back from the hole wall, and calculates the distance from the probe to the hole wall by measuring the time from emission to reception.

[0039] The implementation principle of a hole-forming and trenching detection device under dry hole conditions according to an embodiment of this application is as follows: During detection, the winch 2 is moved to a position a certain distance from the casing 10. After the stranded wire 3 is passed around the large sliding wheel 2411 and the small sliding wheel 2412 respectively, the telescopic bracket 1 is adjusted to the same size and height as the casing 10. The stranded wire 3 passes through two adjacent round pipes 13 on the telescopic bracket 1, and is fixed together with the probe 4 on one of the round pipes 13. It is necessary to ensure that the probe 4 is inside the casing 10 after the telescopic bracket 1 is installed. Then, the telescopic bracket 1 is moved onto the casing 10, and the casing 10 is clamped with the support leg 12. During the transportation process, it is necessary to control the wire reel 21 to release the wire, and at the same time, control the length of the stranded wire 3 to prevent damage to the probe 4. After adjustment, the support leg 1 is... 2. Secure the connecting rod 11 using the locking member 14, and the test can begin. Use the operation button 251 to control the first drive member 26, which in turn controls the reel 21 to release the stranded wire 3, and slowly lower the probe 4. During the lowering of the probe 4, the diameter of the hole is continuously detected using the laser rangefinder 41. When the probe 4 touches the bottom, the force on the stranded wire 3 changes abruptly, and the force on the pedometer 24 also changes abruptly. The pressure sensor 23 detects the force change to determine the detection depth, and the test ends. Then, use the operation button 251 to control the first drive member 26, which retracts the stranded wire 3 from the reel 21. During the retraction, control the second drive member 27 to control the transmission device 22, so that the stranded wire 3 is evenly wound on the reel 21, and the probe 4 is pulled out from the protective sleeve 10, and the test is completed.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
