Description

Technical Field

[0002] A tensioning jack is the core tensioning equipment in a prestressed project. It uses the hydraulic principle to precisely stretch prestressed tendons (such as steel strands, steel bars, etc.), so as to pre-establish stress in concrete components, thereby significantly improving the crack resistance, stiffness, and load-bearing capacity of the structure.

[0003] Existing tensioning jacks mainly consist of a cylinder body, an anchor ring, and anchor plates. A fixing component for fixing the cable is provided inside the cylinder body. During the tensioning operation, first, one end of the cable is passed through the anchor ring, and then the anchor plate is inserted into the gap between the anchor ring and the cable to achieve the preliminary fixation of the cable. Then, the end of the cable is passed through the cylinder body, and the position of the cylinder body is adjusted so that one end thereof is closely attached to the side wall of the anchor ring. After starting the equipment, the output shaft of the cylinder body begins to extend outwards. During this process, the internal fixing component automatically completes the clamping and locking of the cable. As the cylinder body continues to extend, the cable is gradually stretched until the preset length is reached, and the tensioning operation is completed. After the operation is completed, the cylinder body contracts and resets, and the fixing component releases the clamping of the cable accordingly. At this time, the cylinder body can be moved to separate it from the cable, and the anchor plate can be removed to release the cable. Finally, the anchor ring is removed to perform the tensioning operation on the next cable.

[0004] In view of the above related technologies, in an engineering scenario that requires batch tensioning, only one cable can be tensioned at a time. After the operator sequentially completes a series of steps such as threading the cable, fixing, tensioning, and disassembling, the operation on the next cable can be carried out.

[0039] First, fasten the second extension plate 5 to one end of the cylinder block 1 away from the anchor ring 2. Pass multiple cable stays passing through the first extension plate 3 through the corresponding fourth avoidance grooves 81 and second avoidance grooves 51, and the cable stays pass between the third clamping block 61 and the fourth clamping block 62 and fall into the second clamping groove 86. Then tighten the second nut 83. The second screw rod 82 drives the second sliding plate 8 to move towards the second extension plate 5. The second screw rod 82 drives the second guide rod 84 to move. The second guide rod 84 drives the second slider 842 to move. The second slider 842 drives the third clamping block 61 or the fourth clamping block 62 to move. Under the guiding action of the side wall of the second avoidance groove 51, the third clamping block 61 and the fourth clamping block 62 move towards each other, and at the same time drive the two second sliders 842 to move towards each other. The third spring 85 is compressed. As the third clamping block 61 and the fourth clamping block 62 gradually approach, the third clamping block 61 and the fourth clamping block 62 complete the clamping and fixing of the cable stay. After the tensioning is completed, loosen the second nut 83 to make the second sliding plate 8 move away from the second extension plate 5. At the same time, the third spring 85 releases its elastic force and pushes the two second sliders 842 to move away from each other. The two second sliders 842 drive the third clamping block 61 and the fourth clamping block 62 to move. The third clamping block 61 and the fourth clamping block 62 release the clamping and fixing of the cable stay, and then pull out the cable stay from the second avoidance groove 51 and the fourth avoidance groove 81 to carry out the tensioning work for the next batch of cable stays.

[0040] Reference Figure 1 、 Figure 4 and Figure 5 , on the side of the second extension plate 5 facing the first extension plate 3, a second support rod 52 is fixedly installed. The first support rod 33 is on the side of the second extension plate 5 away from the cylinder block 1. The second support rod 52 is inclined. On the side wall of the end of the second support rod 52 away from the second extension plate 5, a second card slot 521 is opened. On the side wall of the end of the anchor ring 2 away from the limit slot 21, a second fixing block 9 is fixedly installed. On the side of the second fixing block 9 away from the anchor ring 2, a second placement groove 91 is opened. On one side wall of the second placement groove 91 of the second fixing block 9, a second moving groove 92 is opened. In the second moving groove 92 of the second fixing block 9, a second clamping block 93 is slidably connected. On the side wall of the second clamping block 93 away from the second placement groove 91, a second pull rod 94 is fixedly installed. The length direction of the second pull rod 94 is perpendicular to the length direction of the anchor ring 2. The end of the second pull rod 94 away from the second clamping block 93 penetrates through the second fixing block 9 and is slidably connected with the second fixing block 9. At the end of the second pull rod 94 away from the second clamping block 93, a second pull plate 95 is fixedly installed. The second pull plate 95 is perpendicular to the second pull rod 94. A fourth spring 96 is fixedly installed between the second pull plate 95 and the second fixing block 9. The fourth spring 96 is sleeved outside the second pull rod 94. The side of the second clamping block 93 away from the second pull plate 95 is set as an inclined surface. The second clamping block 93 and the second card slot 521 are in clamping fit.

[0041] During the process of the second extension plate 5 moving towards the cylinder block 1, the second extension plate 5 drives the second support rod 52 to move. During the movement of the second support rod 52, the end of the second support rod 52 first contacts the inclined surface of the second clamping block 93 and pushes the second clamping block 93 to move towards the second moving groove 92. The second clamping block 93 drives the second pull rod 94 to move, the second pull rod 94 drives the second pull plate 95 to move, and the fourth spring 96 is stretched. After the second extension plate 5 abuts against the cylinder block 1, at this time, the second clamping block 93 is aligned with the second clamping groove 521, and the fourth spring 96 contracts, driving the second pull plate 95 to move towards the second fixed block 9. The second pull plate 95 drives the second pull rod 94 to move, the second pull rod 94 drives the second clamping block 93 to move, and one end of the second clamping block 93 is clamped into the second clamping groove 521, realizing the clamping and fixing of the second support rod 52 and the second fixed block 9. During the process of tensioning the anchor cable, the second support rod 52 supports the end of the second extension plate 5 away from the cylinder block 1, making it difficult for the second extension plate 5 to bend.

[0042] The implementation principle of an efficient anchor for an anchor device used in conjunction with a high-efficiency tensioning jack for a hydraulic lock anchor in an embodiment of the present application is as follows: During the process of batch tensioning operation of the anchor cable, first, the first extension plate 3 is sleeved in the limit groove 21 of the anchor ring 2 and is firmly fixed through the fixing ring 22. Subsequently, the ends of multiple anchor cables are sequentially passed through a plurality of first avoidance grooves 31 evenly distributed on the first extension plate 3, and the first fixing assembly 4 clamps and fixes the anchor cables at the positions of the respective first avoidance grooves 31. Next, the second extension plate 5 is installed at one end of the cylinder block 1 facing away from the anchor ring 2 by bolting, and the ends of the anchor cables that have passed through the first avoidance grooves 31 continue to pass through the corresponding plurality of second avoidance grooves 51 on the second extension plate 5. When the cylinder block 1 is pushed towards the anchor ring 2, the second extension plate 5 moves synchronously with the cylinder block 1 until the extended end of the cylinder block 1 is in close contact with the anchor ring 2. At this time, the second fixing assembly 6 performs secondary clamping and fixing on the anchor cables at the second avoidance grooves 51. Finally, the cylinder block 1 is started to work, realizing the synchronous tensioning operation of multiple anchor cables. The operation time is shortened, and the working efficiency of the tensioning jack for tensioning is improved.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
