Technical Field

[0001] The invention relates to a hydraulic tool, in particular to a quick-lock and quick-release hydraulic tool, belonging to the technical field of foundation engineering construction. Background Art

[0002] When carrying out soil nail wall construction, soil nails are needed to fix the assembled flexible panel on the soil slope. The commonly used soil nails cannot be recycled for secondary use after use. In order to protect the environment, save materials and reduce costs, the soil nails currently used can be recycled and reused, which greatly reduces the one-time consumption cost of the support project and realizes green, environmentally friendly, low-carbon and low-energy construction. At the same time, the use and recycling of soil nails cannot be done solely by manual operation.

[0003] Therefore, the use and recovery of soil nails require the use of special tools to meet current construction needs. Although a variety of hydraulic locking and unloading tools have been produced on the market, in general, there are still many common problems. First, the existing hydraulic tools adopt an integrated structure, which makes it inconvenient to transport. Second, the existing hydraulic tools are not equipped with lock buckles, which makes it impossible to remove the soil nails. Summary of the invention

[0006] Preferably, in order to ensure that the two-piece anchor ring is firmly connected, four fixing plates are provided and arranged in a plum blossom shape and are welded to the two-piece anchor ring.

[0007] Preferably, in order to ensure that the soil nail is completely clamped, the soil nail is clamped and locked by a three-locking plate anchor ring when locking.

[0008] Preferably, in order to prevent the cylinder from being blocked, two through-type leakage holes are provided on the side wall of the cylinder.

[0009] Preferably, in order to quickly unlock the three-locking piece, the spring seat is elastically connected to the three-locking piece via a second spring.

[0010] The beneficial effects of the present invention are as follows: the hydraulic tool is reasonably designed, four fixing plates are provided and arranged in a plum blossom shape, and are welded to the two-piece anchor ring to ensure that the two-piece anchor ring is firmly connected, and the soil nails are clamped and locked by the three-locking plate anchor ring when locking to ensure that the soil nails are completely clamped, two through-type leakage holes are provided on the side wall of the cylinder to prevent the cylinder from being blocked, and the spring seat is elastically connected to the three locking plates through the second spring, so that the three locking plates can be quickly unlocked.
