[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figures 1-4 As shown in the figure, this embodiment proposes a hydraulic unloading device for the first attachment of a wedge-shaped ring on a lifting wire rope, including a lower support 1, an upper support 2, and a hydraulic jack 3. The upper support 2 is installed above the lower support 1. The upper support 2 has a first guide plate 4 and a second guide plate 5 inside. The first guide plate 4 and the second guide plate 5 are arranged vertically and are slidably connected to the upper support 2. The hydraulic jack 3 is located at the top center of the first guide plate 4. The second guide plate 5 has a first mounting seat at the bottom center. A guide shaft 6 is detachably installed in the first mounting seat. The lower end of the guide shaft 6 extends through the bottom of the upper support 2. A top block 7 is located below the bottom of the upper support 2. The top block 7 is detachably installed with the lower end of the guide shaft 6. A wedge-shaped ring clamping mechanism 8 is installed inside the lower support 1. The wedge-shaped ring clamping mechanism 8 is installed with the lower support 1.

[0020] When using the hydraulic unloading device for the first wedge-shaped ring of the lifting wire rope of this utility model, the wedge-shaped rope ring is clamped by the wedge-shaped ring clamping mechanism 8. Then, the hydraulic jack 3 is started. When the output end of the hydraulic jack 3 pushes out, it will contact the upper part of the upper support 2 and can no longer move upward. At this time, the reaction force will push the first guide plate 4 and the second guide plate 5 to move downward, thereby driving the guide shaft 6 to move downward synchronously. Then, the top block 7 at one end of the guide shaft 6 unloads the core of the wedge-shaped rope ring.

[0021] The upper support 2 includes a support plate 201, a top plate 202, and guide rods 203. The top of the support plate 201 is symmetrically provided with guide rods 203, and the top of the two guide rods 203 is provided with a top plate 202. The first guide plate 4 and the second guide plate 5 are slidably connected to the two guide rods 203 at both ends.

[0022] The lower support 1 includes a base plate 101 and a vertical plate 102. The vertical plate 102 is symmetrically arranged on the top of the base plate 101, and the wedge-shaped ring clamping mechanism 8 is installed with the vertical plate 102.

[0023] The support plate 201 has symmetrically arranged sliding plates 9 at its bottom, and the inner side wall of the upright plate 102 has a sliding groove 10. The sliding plate 9 is slidably connected to the sliding groove 10. A locking bolt 11 is provided on one side of the upright plate 102, and multiple locking holes 12 are provided on the sliding plate 9. This utility model allows the upper support 2 to be adjusted in height on the lower support 1 by setting the sliding groove 10. By changing the guide shaft 6 of different lengths, it is possible to perform the ring unloading operation of wedge-shaped rope rings of different sizes. Specifically, this is achieved by moving the sliding plate 9 upward and then connecting it with the corresponding locking hole 12 using the locking bolt 11.

[0024] The wedge-shaped ring clamping mechanism 8 includes a first assembly plate 801, a second assembly plate 802, a bidirectional lead screw 803, and a slide bar 804. The first assembly plate 801 and the second assembly plate 802 are respectively provided on the side walls of the two sets of vertical plates 102. The bidirectional lead screw 803 is rotatably arranged between the two first assembly plates 801, and the slide bar 804 is arranged between the two second assembly plates 802. The slide bar 804 is symmetrically and slidably equipped with locking plates 805. One end of each locking plate 805 is threadedly connected to the bidirectional lead screw 803. One end of the bidirectional lead screw 803 is provided with a knob 806. By rotating the knob 806, the bidirectional lead screw 803 is driven to rotate, causing the two locking plates 805 to move synchronously on the bidirectional lead screw 803 and the slide bar 804, thereby clamping both sides of the wedge-shaped rope ring.

[0025] The slide plate 9 and the support plate 201 are integrally formed, and the first assembly plate 801, the second assembly plate 802 and the upright plate 102 are integrally formed.

[0026] This utility model device uses a hydraulic jack 3 to push out the wedge-shaped rope ring clamped by the wedge-shaped ring clamping mechanism 8. The reverse direction provided by the hydraulic jack 3 drives the guide shaft 6 at the bottom of the second guide plate 5 to move linearly. The top block 7 connected to the lower end of the guide shaft 6 releases the ring core of the wedge-shaped rope ring clamped by the wedge-shaped ring clamping mechanism 8. The ring core release process is highly stable. This utility model device has the advantages of compact and lightweight structure, sturdiness and durability, simple operation, time-saving and high efficiency, stable operation, large supporting force, self-locking, and safety, flexibility and reliability. It is suitable for working in confined spaces.
