Description

Technical Field

[0001] This utility model relates to the field of magnetic measurement technology for reinforcing cage length, and in particular to a device for detecting the length of reinforcing cages in cast-in-place piles using magnetic logging well method. Background Technology

[0002] During the construction of cast-in-place piles, magnetic logging technology is widely used for non-destructive testing of the reinforcement cage length to ensure that the length meets design requirements. Traditional testing methods typically involve placing test holes inside or beside the pile, and determining the actual extension length of the reinforcement cage by measuring the change in magnetic induction intensity along the depth direction of the test holes. In this process, the testing wheel serves as the core component for data acquisition, with one end connected to the instrument host and the other end acting as the testing probe.

[0003] Currently, existing magnetic logging devices for detecting the length of cast-in-place pile reinforcement cages have good overall integrity and high stability due to the integrated design of the detection wheel and the main unit interface. However, the two must be separated during the winding or unwinding operations. Frequent plugging and unplugging operations can easily damage the connection interface to the main unit and reduce the overall detection efficiency and service life of the device. Therefore, there are certain limitations in its use.

[0004] Based on this, we propose a device for detecting the length of the reinforcing cage of cast-in-place piles using magnetic logging to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a device for detecting the length of the reinforcing cage of cast-in-place piles using magnetic logging, which can solve the problems of the existing magnetic logging device for detecting the length of the reinforcing cage of cast-in-place piles, which requires frequent plugging and unplugging due to the integrated design of the detection wheel and the main unit interface, resulting in easy damage to the interface, low detection efficiency and reduced service life.

[0007] To solve the above-mentioned technical problems, this utility model provides a device for detecting the length of the reinforcing cage of a cast-in-place pile using magnetic logging, which adopts the following technical solution: it includes a detection wheel support, one side of which is connected to an adjusting shaft via a bearing, one end of which is fixedly connected to a first pulley blade, and the other end of which is connected to a second pulley blade via a bearing, and a detection wire is wound around the middle of the adjusting shaft, with the detection wire located between the first and second pulley blades;

[0008] A storage cylinder is installed on the outer side of the detection wheel support.

[0009] Optionally, a take-up / release sleeve is connected to one side of the inner side of the second pulley blade, and an adjusting handle is installed on the side of the second pulley blade away from the take-up / release sleeve. The adjusting handle, the second pulley blade, and the take-up / release sleeve are connected in a continuous manner, and the adjusting handle, the second pulley blade, and the take-up / release sleeve are matched with the structure of the detection wire.

[0010] Optionally, an interface fixing seat is provided on one side of both the first pulley blade and the detection wheel support. The interface fixing seat is matched with the detection wire structure. An adjustment seat is installed on the end of the second pulley blade near the take-up and release sleeve. An adjustment positioning component is provided on the top of the adjustment seat.

[0011] Optionally, the adjusting positioning component includes a fixing bolt, one end of which is provided with a toothed clamp.

[0012] Optionally, an adjusting screw hole is provided between the adjusting seat and the second pulley blade and the take-up and unwind sleeve. The adjusting screw hole is matched with the structure of the fixing bolt, and the adjusting screw hole and the fixing bolt are threaded together.

[0013] Optionally, one end of the detection wire is equipped with a host interface, which is located in the middle of the interface mounting base. The end of the detection wire away from the host interface is equipped with a detection probe, which is compatible with the storage cylinder structure.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The detection device designed in this scheme avoids the interface damage caused by frequent plugging and unplugging in traditional integrated designs by optimizing the connection method between the detection wheel and the host interface. By separating the detection wheel from the host interface and using the coordination of the adjustment handle, the cable retraction sleeve and the adjustment seat, efficient cable retraction and untraction can be achieved. This structural design not only reduces interface wear caused by frequent plugging and unplugging, but also significantly extends the service life of the device, resulting in a more stable and reliable detection device that is suitable for various complex construction environments.

[0016] 2. The detection device designed in this scheme can ensure that the detection wire is kept in a neat state during the wire winding process by adjusting the positioning parts and fixing bolts. When the fixing bolts are separated from the adjusting screw hole and the wire winding sleeve, the second pulley blade can be rotated clockwise to perform the wire winding operation; when the fixing bolts are connected to the adjusting screw hole and the wire winding sleeve, the second pulley blade can be rotated counterclockwise to perform the wire winding operation. This adjustment method can effectively avoid measurement errors caused by tangled cables, improve the accuracy and reliability of detection, and enhance the flexibility and practicality of the device in the field of rebar cage length detection technology.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a device for detecting the length of a cast-in-place pile reinforcement cage using magnetic logging. The device includes a detection wheel support 1. One side of the detection wheel support 1 is connected to an adjusting shaft 2 via a bearing. One end of the adjusting shaft 2 is fixedly connected to a first pulley blade 3. The end of the adjusting shaft 2 away from the first pulley blade 3 is connected to a second pulley blade 4 via a bearing. A detection wire 5 is wound around the middle of the adjusting shaft 2, located between the first pulley blade 3 and the second pulley blade 4. A storage cylinder 6 is installed on the outer side of the detection wheel support 1. This detection device solves the problem of traditional detection equipment requiring frequent plugging and unplugging of the main unit during wire winding and unwinding operations. The second pulley plate 4 has a take-up / reel-out sleeve 7 connected to one side of its interior. An adjustment handle 8 is installed on the side of the second pulley plate 4 away from the take-up / reel-out sleeve 7. The adjustment handle 8, the second pulley plate 4, and the take-up / reel-out sleeve 7 are connected in a continuous manner. The adjustment handle 8, the second pulley plate 4, and the take-up / reel-out sleeve 7 are structurally compatible with the detection wire 5. Through the adjustment handle 8 installed on the second pulley plate 4, and the continuous connection between the adjustment handle 8, the second pulley plate 4, and the take-up / reel-out sleeve 7, the detection wire 5 can be guided and transported during the take-up or reel-out process.

[0026] Both the first pulley blade 3 and the detection wheel support 1 are provided with interface fixing seats 9 on one side. The interface fixing seats 9 are matched with the structure of the detection wire 5. The second pulley blade 4 is equipped with an adjusting seat 10 at one end near the take-up and release sleeve 7. The top of the adjusting seat 10 is provided with an adjusting positioning component 11. By adding interface fixing seats 9 to one side of the first pulley blade 3 and the detection wheel support 1 respectively, and the interface fixing seats 9 are matched with the structure of the detection wire 5, the connection host interface 15 added to one end of the detection wire 5 can play a double fixing role. The adjusting positioning component 11 includes a fixing bolt 12. One end of the fixing bolt 12 is provided with a toothed clamp 13. By adding the toothed clamp 13 to one end of the fixing bolt 12, the adjusting handle 8, the second pulley blade 4, and the detection wire 5 connected inside the take-up and release sleeve 7 can be fixed or released.

[0027] An adjusting screw hole 14 is provided through the adjusting seat 10, the second pulley blade 4, and the take-up / release sleeve 7. The adjusting screw hole 14 is structurally matched with the fixing bolt 12, and the adjusting screw hole 14 and the fixing bolt 12 are threaded together. Through the structural design of the threaded engagement between the adjusting screw hole 14 and the fixing bolt 12, when the fixing bolt 12 is separated from the adjusting screw hole 14 and the take-up / release sleeve 7, rotating the second pulley blade 4 clockwise can release the detection wire 5. When the fixing bolt 12 is separated from the adjusting screw hole 14 and the take-up / release sleeve 7, the wire can be released by rotating the second pulley blade 4 clockwise. When 7 is in the connected state, rotating the second pulley blade 4 counterclockwise can retract the detection wire 5. One end of the detection wire 5 is equipped with a host interface 15, which is located in the middle of the interface fixing base 9. The end of the detection wire 5 away from the host interface 15 is equipped with a detection probe 16. The detection probe 16 is matched with the structure of the storage cylinder 6. The matching design of the detection probe 16 with the structure of the storage cylinder 6 makes it easy to store and place the detection probe 16 attached to one end of the detection wire 5 inside the storage cylinder 6.

[0028] Working Principle: The detection device designed in this scheme mainly consists of a detection wheel support 1, an adjusting shaft 2, a first pulley blade 3, a second pulley blade 4, and a detection wire 5. When the second pulley blade 4 is rotated clockwise or counterclockwise, it works in conjunction with the wire take-up sleeve 7, the adjusting handle 8, and the adjusting seat 10. Because the adjusting handle 8, the second pulley blade 4, the wire take-up sleeve 7, and the detection wire 5 are structurally matched, the detection wire 5 wound around the middle of the adjusting shaft 2 can be unwound or rewound. The second pulley blade 4 works in conjunction with the adjusting seat 10 and the adjusting positioning part 11. When the fixing bolt 12 is separated from the adjusting screw hole 14 and the wire take-up sleeve 7, clockwise rotation of the second pulley blade 4 can unwound the detection wire 5. When the fixing bolt 12 is connected to the adjusting screw hole 14 and the wire take-up sleeve 7, counterclockwise rotation of the second pulley blade 4 can rewound the detection wire 5.

[0029] The above adjustment method can solve the problem of the need for frequent plugging and unplugging of the host interface 15 during the wire winding and unwinding operation of traditional detection equipment. At the same time, this adjustment method can also ensure that the detection wire 5 can be easily adjusted to a neat state during the wire winding process, thereby improving the flexibility and practicality of the equipment in the field of magnetic measurement of rebar cage length.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
