Description

Technical Field

[0001] This utility model belongs to the field of grouting effect detection technology, and specifically relates to a grouting effect detection device. Background Technology

[0002] In construction engineering and mine reinforcement, grouting is a key technology for ensuring project stability. It involves injecting grout into cavities to fill them and enhance the structure's load-bearing capacity. After grouting is completed, accurate monitoring of the grouting effect is essential for ensuring project quality. Currently, common methods for monitoring grouting effectiveness include ground-penetrating radar (GPR), acoustic wave detection, and core drilling. However, these methods all face challenges in practical operation, such as difficulties in positioning the testing equipment and poor testing stability.

[0003] For example, when using core drilling or insertion-type inspection equipment, the inspection head needs to be inserted deep into the borehole. However, due to the lack of an effective guiding structure, the inspection head is prone to displacement and shaking inside the borehole, resulting in deviations in the inspection data and affecting the accuracy of the inspection results. At the same time, existing inspection equipment is difficult to adapt to boreholes of different diameters. When faced with inspection requirements for boreholes of varying sizes, it is necessary to frequently change the matching equipment, resulting in low inspection efficiency and poor equipment versatility.

[0004] To address this issue, another grouting effect testing device is provided. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a grouting effect detection device to solve the problems of difficulty in positioning the detection equipment in the borehole, easy displacement and shaking during the detection process leading to data deviation, difficulty in adapting to boreholes of different diameters requiring frequent equipment replacement, and affecting detection efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grouting effect testing device includes a hollow T-shaped base. A hollow tube is welded and fixedly installed on the upper surface of the T-shaped base. A sleeve block is slidably fitted on the outer surface of the hollow tube. A locking element is provided between the sleeve block and the hollow tube. At least three hinge members are welded circumferentially at equal intervals on the outer surfaces of the sleeve block and the T-shaped base. A hinge rod is hinged between two corresponding upper and lower hinge members. A guide device is fixedly installed on the side of the hinge rod away from the hollow tube. A detection head is detachably installed at the lower end of the T-shaped base. The signal output terminal of the detection head is electrically connected to a data transmission line. The data transmission line extends through the inner cavity of the T-shaped base and the hollow tube to the outside of the hollow tube and is connected to an external grouting effect testing instrument.

[0008] In the above technical solution, each hinge component includes two lugs, with the upper lug fixedly connected to the sleeve block and the lower lug fixedly connected to the T-shaped seat.

[0009] In the above technical solution, the hinge rod includes an upper rod and a lower rod. The adjacent ends of the upper rod and the lower rod are hinged together by a pivot. The upper end of the upper rod is hinged between the two upper lugs by a pivot, and the lower end of the lower rod is hinged between the two lower lugs by a pivot.

[0010] In the above technical solutions, the guiding device includes a wheel frame, which is fixedly installed on the outer surface of the corresponding lower rod, and a roller is rotatably installed inside the wheel frame.

[0011] In the above technical solution, the front surface of the hollow tube is provided with multiple positioning holes at equal intervals in a vertical direction, and the front surface of the sleeve is threaded with a locking bolt, the rear end of the locking bolt being snapped into the corresponding positioning hole.

[0012] In the above technical solution, the top end of the detection head is screwed into the inner cavity of the T-shaped seat.

[0013] In the above technical solution, two C-shaped plates are symmetrically rotated and installed on the upper outer surface of the hollow tube. Each C-shaped plate has a hanging groove in the middle of its inner side, and corresponding clamping grooves are opened on the opposite surfaces of the two C-shaped plates. The data transmission line is located between the two clamping grooves.

[0014] The grouting effect detection device of this utility model has the following advantages compared with the prior art:

[0015] This invention provides an internal wiring channel for the data transmission line by configuring a hollow T-shaped seat and a hollow tube, thus providing protection. Through the sliding fit between the sleeve and the hollow tube, along with locking components, multiple vertical positioning holes and locking bolts on the hollow tube, the position of the sleeve can be flexibly adjusted, thereby changing the included angle of the hinge rod and driving the guide device to move, precisely adapting to drilling holes of different diameters, thus enhancing the device's versatility. The hinge rod adopts a segmented structure, making adjustment more flexible. Precise guidance is achieved by utilizing the rollers of the guide device in contact with the inner wall of the hole. The hanging groove and clamping groove of the C-shaped plate provide double protection for the data transmission line. These structural designs effectively solve the problems existing in current grouting effect detection methods, such as difficulty in positioning the detection equipment, poor detection stability, difficulty in adapting to drilling holes of different diameters, poor equipment versatility, inconvenient replacement and maintenance of the detection head, and easy damage to the data transmission line. This effectively improves the accuracy, efficiency, and reliability of the detection data. Attached Figure Description

[0022] 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.

[0023] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:

[0024] A grouting effect testing device includes a hollow T-shaped seat 1. A hollow tube 2 is welded and fixedly installed on the upper surface of the T-shaped seat 1. A sleeve block 3 is slidably fitted on the outer surface of the hollow tube 2. A locking element is provided between the sleeve block 3 and the hollow tube 2. At least three hinge pieces 4 are welded circumferentially at equal intervals on the outer surface of both the sleeve block 3 and the outer surface of the T-shaped seat 1. A hinge rod 5 is hinged between two corresponding upper and lower hinge pieces 4. A guide device 6 is fixedly installed on the side of the hinge rod 5 away from the hollow tube 2. A detection head 11 is detachably installed at the lower end of the T-shaped seat 1. The signal output terminal of the detection head 11 is electrically connected to a data transmission line 111. The data transmission line 111 extends through the inner cavity of the T-shaped seat 1 and the hollow tube 2 to the outside of the hollow tube 2 and is connected to an external grouting effect testing instrument. This ensures that the test data can be transmitted in a timely and accurate manner, providing a reliable basis for the evaluation of the grouting effect.

[0025] By setting up hollow T-shaped base 1 and hollow tube 2, the overall weight of the device is reduced, making it easier to operate and transport. On the other hand, it provides an internal wiring channel for data transmission line 111, effectively protecting data transmission line 111 and preventing it from being interfered with or damaged by external factors during use.

[0026] The sliding fit between the sleeve 3 and the hollow tube 2, along with the locking mechanism, allows for flexible adjustment of the position of the sleeve 3 on the outer surface of the hollow tube 2. This changes the angle of the hinge rod 5, causing the guide device 6 to move inward or outward by a different distance. This flexibly adjusts the position to meet the needs of adjusting the actual borehole diameter, enhancing the versatility and applicability of the device. Furthermore, the guide device 6 ensures the smooth downward movement of the detection head 11 within the borehole, effectively preventing deviation and swaying during the detection process, thereby improving the accuracy and reliability of the detection data.

[0027] In the above technical solution, the hinge 4 includes two lugs. The upper lug is fixedly connected to the sleeve block 3, and the lower lug is fixedly connected to the T-shaped seat 1. The hinge rod 5 includes an upper rod 51 and a lower rod 52. The adjacent ends of the upper rod 51 and the lower rod 52 are hinged together by a pivot. The upper end of the upper rod 51 is hinged between the two upper lugs by a pivot, and the lower end of the lower rod 52 is hinged between the two lower lugs by a pivot.

[0028] The segmented hinge rod 5 design allows for more flexible angle adjustments during the adjustment of the sleeve block 3. When the sleeve block 3 slides on the hollow tube 2, the upper rod 51 and lower rod 52 can rotate around the hinge axis, thereby driving the guide device 6 to accurately adjust its position to adapt to drilling holes of different diameters. This flexible adjustment method not only improves the device's adaptability to different hole diameters but also ensures that the guide device 6 remains in close contact with the borehole wall, providing stable support and guidance for the detection head 11, effectively reducing shaking during the detection process and improving detection accuracy.

[0029] Each guide device 6 includes a wheel frame 61, which is fixedly installed on the outer surface of the corresponding lower rod 52. Rollers 62 are rotatably installed inside each wheel frame 61. In actual use, the rollers 62 can contact the inner wall of the hole to achieve the guiding function.

[0030] In addition, multiple positioning holes 21 are vertically and equidistantly opened on the front surface of the hollow tube 2, and a locking bolt 31 is threaded through the front surface of the sleeve block 3. The rear end of the locking bolt 31 is snapped into the corresponding positioning hole 21.

[0031] The positioning holes 21 and locking bolts 31 work together to provide precise positioning for adjusting the sleeve 3. When the position of the sleeve 3 needs to be adjusted, simply loosen the locking bolts 31, slide the sleeve 3 to the appropriate position, and then tighten the locking bolts 31 to make it engage with the corresponding positioning holes 21, thus fixing the sleeve 3 in place. The multiple positioning holes 21 can meet the adjustment requirements of drilling holes of different diameters, ensuring that the sleeve 3 can be stably fixed on the hollow tube 2 after adjustment, preventing the sleeve 3 from sliding during the testing process, thereby ensuring the stability of the testing process and the accuracy of the test data.

[0032] In addition, the top of the detection head 11 is screwed into the inner cavity of the T-shaped seat 1. The detection head 11 is installed in the T-shaped seat 1 by screwing, which facilitates the replacement and maintenance of the detection head 11 and reduces the operating cost of the equipment.

[0033] Finally, two C-shaped plates 7 are symmetrically rotated and installed on the upper outer surface of the hollow tube 2. Each C-shaped plate 7 has a hanging groove 71 in the middle of its inner side, and a clamping groove 72 is correspondingly opened on the opposite surface of the two C-shaped plates 7. The data transmission line 111 is located between the two clamping grooves 72.

[0034] The C-shaped plate 7 provides double protection for the data transmission line 111. The mounting slot 71 can be used to hang external equipment or tools, facilitating the carrying and use of the device. The clamping slot 72 can lightly clamp and fix the data transmission line 111, preventing it from shaking or being pulled during device use, avoiding damage or poor contact, ensuring that the test data can be stably and accurately transmitted to the external grouting effect inspection instrument, and improving the reliability of the test results.

[0035] Working principle: In use, firstly, according to the diameter of the borehole to be inspected, loosen the locking bolt 31 on the sleeve 3, and slide the sleeve 3 on the hollow tube 2 to a suitable position. At this time, the sleeve 3 drives the hinge 4 to move, which in turn causes the upper rod 51 and lower rod 52 of the hinge rod 5 to rotate around the pivot, changing the angle of the hinge rod 5 and driving the roller 62 to adjust its position until the roller 62 adapts to the borehole diameter. After adjustment, tighten the locking bolt 31 so that it is engaged in the corresponding positioning hole 21, fixing the sleeve 3 on the hollow tube 2. Then, install the detection head 11, and connect the data transmission line 111 of the detection head 11 to the external grouting effect inspection instrument through the T-shaped seat 1 and the inner cavity of the hollow tube 2.

[0036] Then, using an external rope with a hook, hooked in the mounting groove 71 of the C-shaped plate 7, the entire device, carrying the detection head 11, is slowly inserted into the borehole until it contacts the inner wall. The roller 62 and hinged rod 5 provide support and guidance for the detection device, ensuring the detection head 11 can be smoothly lowered into the hole for inspection. During the inspection, the grouting effect is evaluated using an external grouting effect inspection instrument. After the inspection is completed, the detection device can be removed from the borehole. If the detection head 11 needs to be replaced, it can be replaced by unscrewing the threaded connection between the top of the detection head 11 and the T-shaped seat 1.
