Description

Technical Field

[0001] This utility model relates to an anchor cable tension adjustment device and an anchor cable structure. It is applicable to the field of anchor cable structure technology. Background Technology

[0002] Anchor cables are mainly used in geotechnical engineering, slope reinforcement, tunnel support and foundation pit support. By applying prestress, they can improve structural stability, effectively control deformation, enhance the integrity of the rock mass, and extend the service life of the project. However, during construction, the control of anchor cable tension may encounter the following problems: (1) Inaccurate tension: Improper operation by construction personnel or insufficient equipment precision may result in tension not meeting design requirements, affecting structural safety. (2) Anchor cable stress relaxation: Affected by the characteristics of rock mass, anchor cable, and anchor material, the prestress of the anchor cable may gradually decrease over time. (3) High safety risk of anchor cable stress: Affected by the deformation of the surrounding rock, the anchor cable stress may approach or exceed the design value. If the anchor cable stress is not intervened in time, the anchor cable may break, further increasing the project risk. Utility Model Content

[0016] The beneficial effects of this utility model are as follows: This utility model facilitates the installation of anchor cables on soil and rock by anchoring the anchor cables to the soil and rock mass and installing anchor plates on the anchor cables extending beyond the soil and rock mass, thus providing good support. This utility model also facilitates the installation of anchor cables on soil and rock mass by sequentially installing a first anchor plate and a second anchor plate on the anchor cable, and installing a hydraulic disc mechanism between the first and second anchor plates, allowing the anchor cable to pass through the mounting hole of the hydraulic disc mechanism. The hydraulic disc mechanism has a hydraulic base and a hydraulic movable disc, with a hydraulic chamber inside the hydraulic base and a hydraulic valve installed at the lower end of the hydraulic movable disc.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] This embodiment is an anchor cable structure.

[0024] In this embodiment, there is an anchor cable 7 anchored in the rock and soil body 4, with the top end of the anchor cable 7 extending out of the rock and soil body 4. An anchor 8 is fixedly installed on the anchor cable 7 extending out of the rock and soil body 4, which facilitates the installation of the anchor cable 7 on the rock and soil body 4.

[0025] In this embodiment, a first anchor plate 5 and a second anchor plate 6 are installed on the anchor cable 7 between the anchor and the rock and soil body 4. The second anchor plate 6 is located above the first anchor plate 5. An adjustment device is installed on the anchor cable 7 between the first anchor plate 5 and the second anchor plate 6.

[0026] In this embodiment, the adjusting device has a hydraulic disc mechanism 1, a hydraulic chassis 13 and a hydraulic movable disc 14. A hydraulic chamber 16 is provided inside the hydraulic chassis 13. A hydraulic piston head 15 is installed at the lower end of the hydraulic movable disc 14. The hydraulic piston head 15 extends into the hydraulic chamber 16 and slides in cooperation with the hydraulic chamber 16. An inlet hole 12 is formed on the side wall of the hydraulic chamber 16 below the hydraulic piston head 15. The inlet hole 12 is connected to a storage tank through a delivery pump 11. The delivery pump 11 is installed on the storage tank. The first end of the delivery pump 11 is connected to a first delivery pipe that extends into the storage tank. The second end of the delivery pump 11 is connected to the inlet hole 12 on the hydraulic chassis 13 through a second delivery pipe. Thus, the infusion pump 11 facilitates the input of the liquid stored in the storage tank into the hydraulic chamber 16, so that the hydraulic piston head 15 and the hydraulic movable plate 14 can extend and retract under the pressure change in the hydraulic chamber 16, thereby adjusting the position between the first anchor plate 5 and the second anchor plate 6, and thus adjusting the tension of the anchor cable 7.

[0027] In this embodiment, the hydraulic chamber 16 of the hydraulic chassis 13 has an annular cross-section, and the mounting hole is located at the center of the hydraulic chamber 16 on the hydraulic disc mechanism 1. This facilitates a more uniform force distribution between the hydraulic chassis 13 and the first anchor plate 5, and between the hydraulic movable disc 14 and the second anchor plate 6, resulting in better structural stability.

[0028] In this embodiment, a pressure sensor 9 is installed on the hydraulic movable disc 14. The pressure sensor 9 can obtain the pressure information between the hydraulic movable disc 14 and the second anchor plate 6. The tension state of the anchor cable 7 can be determined based on the pressure information between the hydraulic movable disc 14 and the second anchor plate 6.

[0029] In this embodiment, both the infusion pump 11 and the pressure sensor 9 are communicatively connected to the controller 3. The controller 3 can receive pressure information acquired by the pressure sensor 9. When the received pressure information is lower than a preset low pressure value within the controller 3, the controller 3 can control the drive mechanism to operate and cause the telescopic movable disc to extend. When the received pressure information is higher than a preset high pressure value within the controller 3, the controller 3 can control the drive mechanism to operate and cause the telescopic movable disc to retract. This enables automatic adjustment of the anchor cable 7 tension.

[0030] In this embodiment, a display 2 is provided that is communicatively connected to the controller 3. The display 2 can display the pressure information acquired by the pressure sensor 9. This makes it convenient for personnel to view the pressure information.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
