Description

Technical Field

[0001] This utility model relates to the field of anchor cable prestress testing technology, specifically to an efficient non-destructive testing device for anchor cable prestress. Background Technology

[0002] Anchor cables are structural components used to provide prestress and are widely used in various engineering structures. Anchor cable prestressing refers to the use of steel cables, reinforcing bars, or other materials in a structure to increase its load-bearing capacity and resistance to deformation by applying a predetermined tension (i.e., prestress). During the construction phase of prestressed structures, the tension and application sequence of the anchor cables must be strictly controlled to ensure that the anchor cable tension meets design requirements. Therefore, a highly efficient and non-destructive testing device for anchor cable prestressing is needed to test the anchor cables without damaging them, ensuring that the construction quality meets the expected standards.

[0003] The existing technology has the following shortcomings:

[0004] 1. When using tensioning equipment to test anchor cables, the existing high-efficiency non-destructive testing device for anchor cable prestress usually requires the use of external suspension ropes to fix the suspended tensioning equipment because the tensioning equipment itself does not have a support structure. However, when testing some low-height anchor cables, it is often wasteful and troublesome to install additional suspension ropes.

[0005] 2. When the existing tensioning equipment of the high-efficiency non-destructive testing device for anchor cable prestress is transported by a transport vehicle, the bottom of the tensioning equipment is usually in hard contact with the vehicle body. Due to the vibration of the vehicle body during transportation, the tensioning equipment is prone to vibration and collision. The vibration reduction effect of the tensioning equipment of the high-efficiency non-destructive testing device for anchor cable prestress can be further improved during transportation.

Ultimately, it can further enhance the shock absorption effect of the tensioning equipment during transportation. Attached Figure Description

[0027] Specifically, the fixing plate 6 facilitates the installation of the mounting block 7;

[0028] In this embodiment, one end of the threaded rod 10 is fixedly installed on one side of the mounting block 7, and the nut 11 is threadedly connected to the threaded rod 10.

[0029] Specifically, the threaded rod 10 facilitates the installation of the support rod 8 and the nut 11;

[0030] In this embodiment, the top end of the support rod 8 is provided with an opening that is compatible with the threaded rod 10, and this opening is not a threaded hole. The top end of the support rod 8 is sleeved on the threaded rod 10.

[0038] The working principle and usage process of this utility model are as follows: One set of anchor rods of the anchor cable 3 to be tested is passed through the testing port of the tensioning device 1. If the anchor cable 3 is installed at a high height, the suspended tensioning device 1 is fixed using an external suspension rope. If the anchor cable 3 is installed at a low height, the four sets of nuts 11 are rotated sequentially to move them away from their corresponding support rods 8. The four sets of support rods 8 are then rotated sequentially to bring their bottoms closer to the ground. Simultaneously, the fixing frame 901 is rotated so that the bottom of the base block 902 is in contact with the ground. The four sets of nuts 11 are then rotated sequentially to ensure they are in contact with the support rods 8. Tightening the washers 12 further tightens the nuts 11 against the support rods 8. At this point, both sides of the support rods 8 are respectively in contact with… Nut 11 and mounting block 7 are tightly attached, and support rod 8 will not rotate arbitrarily. Support rod 8, together with fixing component 9, can support tensioning equipment 1 and fix tensioning equipment 1. Connect the connecting pipeline of the output device of tensioning equipment 1 to terminal 5. Tensioning equipment 1 uses piezoelectric ceramic sensor to detect stress change of anchor cable 3. The detection range of sensor covers different sections of anchor cable 3, which can achieve segmented and efficient detection of anchor cable 3 and is not easy to damage anchor cable. This structure can support and fix tensioning equipment 1 through its own support structure when detecting some low-height anchor cables 3, without the need to install additional lifting ropes.

[0039] Furthermore, when the tensioning device 1 is transported by a transport vehicle, the spring 903 combined with the damping component 904 can achieve a good shock absorption effect, and the anti-slip block 905 can improve the anti-slip properties of the bottom block 902, thereby improving the placement stability of the tensioning device 1. Ultimately, this can further enhance the shock absorption effect of the tensioning device 1 during transportation.
