Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a rapid testing instrument for the grouting fullness of water conservancy and hydropower engineering. Background Technology

[0002] In water conservancy and hydropower projects, sleeve grouting is a key construction technique, mainly used for the connection of prefabricated reinforced concrete structures. This technology uses special grouting sleeves and high-strength non-shrink grout to achieve a reliable connection between steel bars. This connection method has many advantages, including high construction efficiency, good stress performance, low additional stress, and wide applicability. However, the quality and safety of grouting sleeve connections are highly dependent on the fullness of the cement-based grout. If the grout inside the sleeve is not full, the performance of the steel bar connection will not meet the design requirements, which may lead to serious structural safety hazards.

[0003] Endoscopic methods involve directly observing the grouting material inside the grouting sleeve using an endoscopic camera. For example, in a method for inspecting the fullness of grouting material in a steel rebar sleeve, an endoscopic camera is inserted into the inspection hole to take pictures of the surface of the grouting material, and then the fullness of the grouting material is determined by analyzing the pictures.

[0004] When using an endoscopic camera to detect the saturation of grout inside a sleeve, the endoscopic camera needs to be connected to the controller via a long cable harness. Therefore, if the cable harness is not stored properly during transport, it is easily damaged. Once the cable harness is damaged, it will directly affect the normal connection between the endoscopic camera and the controller, thus affecting the smooth progress of the detection work. Therefore, in order to address the above problems, a rapid detection instrument for grout fullness in water conservancy and hydropower projects is proposed. Utility Model Content

[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 of the present utility model. 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] Please see the appendix Figure 1-6 This embodiment discloses a rapid testing instrument for grout fullness in water conservancy and hydropower projects: It includes a testing instrument body, with a wire group protective cylinder 2 fixedly connected to the rear end of the testing instrument body. The wire group protective cylinder 2 has a cavity, and a winding post 26 is fixedly connected to the cavity. A wire 22 is wound on the winding post 26. One end of the wire 22 passes through the wire group protective cylinder 2 and is fixedly connected to the testing instrument body. The other end of the wire 22 is connected to a wiring assembly 3. The wiring assembly 3 includes a support rod located within the cavity and revolving around the winding post 26. A central block 35 is connected to the support rod, and an embedded post 36 is fixedly connected to the top of the central block 35. A threaded track 24 for sliding the embedded post 36 is provided inside the wire group protective cylinder 2. A rubber ball 37 is fixedly connected to the lower end of the central block 35, and a fitting hole 38 for the wire 22 to pass through is provided on the rubber ball 37.

[0024] The instrument body functions the same as existing instruments used for detecting grout saturation. This application does not improve the function of the instrument itself; the instrument body is prior art and will not be described in detail here. The main improvement of this application is that a wire group protective sleeve 2 is added to the rear end of the instrument body. The wire group protective sleeve 2 is fixedly connected to the outer shell of the instrument body by fixing screws. Figure 3As shown, the wire 22 used to connect the instrument body and the probe is wound inside the inner cavity of the wire group protective cylinder 2. This way, when the instrument is moved, the wire 22 can be stored inside the wire group protective cylinder 2 to prevent the wire 22 from being worn during movement. The left end of the wire 22 is connected to the instrument body through the through hole on the winding post 26 and the wiring hole on the outer plate 23. The other end of the wire 22 passes through the wiring assembly 3 and is connected to the probe.

[0025] The support rod inside the wiring assembly 3 is located on the side of the winding post 26 and is located in the cavity. During wiring, the support rod revolves around the winding post 26. The rotation of the support rod drives the central block 35 to rotate, which in turn drives the rubber ball 37 to rotate. The rotation of the rubber ball 37 winds the wire 22 around the winding post 26. To further prevent the wire 22 from getting tangled on the winding post 26, an embedded post 36 is fixedly connected to the central block 35. At the same time, the casing 21 has a threaded track 24 inside. When the central block 35 rotates, the embedded post 36 on the central block 35 will move along the threaded track 24. Under the action of the threaded track 24, the central block 35 has a lateral movement during the movement, which can evenly wind the wire 22 around the winding post 26, avoid messy wiring, and ensure that the wire 22 is neatly and orderly arranged in the wire assembly protection cylinder 2.

[0026] The outer board 23 has a cable tray 25 on its inner side, and the line 22 is located inside the cable tray 25. The line 22 is electrically connected to the main body 1 of the testing instrument. Through the above settings, this design not only ensures the stability of signal transmission, but also reduces the external damage to the line 22 during use and extends the service life of the cable.

[0027] The inner side of the threaded track 24 fits against the outer side of the embedded post 36. The opening shape of the threaded track 24 is a spiral structure. Through the above-mentioned arrangement, the fitting design of the inner side of the threaded track 24 against the outer side of the embedded post 36, combined with the opening shape of the spiral structure, provides a clear path for the movement of the embedded post 36. This design not only improves the stability and accuracy of the movement of the embedded post 36, but also enhances the overall performance and reliability of the device through the guiding effect of the spiral structure.

[0028] The housing 21 has an installation groove on its inner side near the servo motor 33. There is a gap between the inner side of the housing 21 and the outer side of the gear disk 31. A bearing is fixedly connected to the inner side of the gear disk 31. The gear disk 31 is rotatably connected to the winding post 26 through the bearing. Through the above arrangement, a stable installation position is provided for the servo motor 33, ensuring the structural stability of the device. The rotatable connection between the gear disk 31 and the winding post 26 through the bearing reduces friction, improves rotation efficiency, and extends the service life of the device.

[0029] The fitting hole 38 extends through the inner side of the rubber ball 37 on both sides. Both ends of the fitting hole 38 are extended structures. The inner side of the fitting hole 38 fits with the outer side of the line 22. Through the above settings, the stability of the line 22 is ensured during storage and use, and the rubber ball 37 reduces the shaking and wear of the cable.

[0030] Workflow: When the line 22 is retracted, the multi-stage telescopic rod 34 is in the retracted state, and the mounting post 36 is located inside the front end of the housing 21. The servo motor 33 is activated, driving the gear 32 to rotate. The gear 32 drives the outer meshing gear disc 31 to rotate, which in turn drives the multi-stage telescopic rod 34 and the entire device at its rear end to rotate. During the rotation of the mounting post 36, because it is located inside the threaded track 24, the mounting post 36 moves backward. This causes the center block 35 and the rubber ball 37 to move backward, at which point the multi-stage telescopic rod 34 extends. The rubber ball 37 moves backward in a spiral trajectory. The rubber ball 37 is made of rubber and fits against the outside of the wire 22. This provides a certain pre-tightening force when storing the wire 22, improving the stability and orderliness of storing the wire 22. The wire 22 is inside the fitting hole 38. At this time, the wire 22 will be wrapped around the outside of the winding post 26 in a spiral shape. This storage method does not require manual handling, reduces the pulling intensity of the staff, and avoids the wire 22 from scratching against external objects due to its excessive length, improving the safety of using the wire 22 and making it easy to carry.

[0031] When the device is in use, the spindle of the servo motor 33 is rotated in the opposite direction, which pulls the line 22 outward. At this time, the fitting hole 38 will move in a backward spiral trajectory, so that the line 22 is unwound on the outside of the winding post 26. At the same time, the line 22 can extend backward. By inserting the probe into the inside of the sleeve, the saturation of the grout can be detected.

[0032] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
