Description

Technical Field

[0001] The present application relates to the technical field of tensioning jacks, and in particular to a high-efficiency tensioning jack with a hydraulic anchoring function. Background Art

[0002] Tensioning jack is a hydraulic equipment used in prestressed construction. It is mainly used for high-precision tensioning of steel bars, steel strands or steel wire bundles. It is widely used in concrete structures such as bridges, buildings, and sleepers to enhance their crack resistance and bearing capacity.

[0003] The existing tensioning jack structure primarily consists of an anchor ring, multiple circumferentially arranged anchor plates, and a cylinder housing an internal anchor cable fixing assembly. The anchor plates slide along the inner wall of the anchor ring to hold the anchor cable, while the cylinder, driven by an oil pump, telescopes and retracts to complete the tensioning operation.

[0004] To do this, first thread the anchor cable through the anchor ring and tap the anchor plate with a tool to secure it. The cable is then threaded into the cylinder, where the end of the cylinder contacts the anchor ring. Activating the tensioning pump causes the cylinder to extend outward, driving the internal fixing assembly to lock onto the anchor cable, gradually tensioning it as the cylinder moves. When the desired tension is reached, the cylinder retracts, releasing the fixing assembly and facilitating removal. Finally, pull the anchor plate outward to release the cable, and remove the anchor ring, completing the tensioning process.

[0005] Regarding the above-mentioned related technologies, since the workers hold the cylinder body and the anchor ring in abutment, during the tensioning process, the vibration generated by the equipment can easily cause the cylinder body and the anchor ring to deflect, forming local stress concentration. This misaligned abutment state will cause the anchor cable to bear eccentric loads, resulting in uneven force on the steel wires inside the anchor cable. Some steel wires may reach the yield strength prematurely due to overload, while the other part fails to fully exert its bearing role, resulting in the defect of poor tensioning effect of the tensioning jack.

A first fixing hole 331 and a second fixing hole 332 are penetrated by a side wall of the rotating shell 33 close to the third auxiliary plate 38, and the fixing rod 381 and the first fixing hole 331 are plugged in and adapted, and the fixing rod 381 and the second fixing hole 332 are plugged in and adapted.

[0046] When the locking cam 33 is unlocked, the locking cam 33 is unlocked and the locking cam 33 is unlocked, so that the cam 33 is unlocked and the locking cam 33 is unlocked.

[0047] refer to Figure 1 and Figure 2 A clearance groove 9 is defined on the side of the first push block 322 away from the first screw rod 62 and the side of the second push block 361 away from the second screw rod 82. The clearance groove 9 extends through opposite sides of the first push block 322 or the second push block 361. When the first push block 322 pushes the first pull plate 42, the clearance groove 9 on the first push block 322 clears the first spring 31 and the first latching rod 41.

[0048] The implementation principle of a high-efficiency tensioning jack with a hydraulic anchor locking function in the embodiment of the present application is as follows: First, the anchor cable is passed through the anchor ring 2, and the anchor plate 21 is inserted into the gap between the anchor cable and the anchor ring 2 to complete the clamping and fixing of the anchor cable. Next, one end of the connecting pipe 3 is placed on the extended end of the cylinder body 1. After the end of the connecting pipe 3 abuts the first abutment plate 12, the connecting pipe 3 and the cylinder body 1 are fixed by the first clamping assembly 4. Subsequently, the anchor cable is passed through the cylinder body 1 and the cylinder body 1 is moved toward the anchor ring 2, driving the connecting pipe 3 forward together. When the other end of the connecting pipe 3 abuts the second abutment plate 22, the cylinder body 1 and the anchor ring 2 are simultaneously engaged. At this time, the second clamping assembly 5 completes the fixing of the connecting pipe 3 and the anchor ring 2, thereby forming a rigid connection between the anchor ring 2 and the cylinder body 1. During the tensioning process, the cylinder body 1 is not easily deflected from the anchor ring 2 due to vibration, ensuring the stability and accuracy of the prestressing and improving the tensioning effect of the tensioning jack.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
