[0038] Example 1:

[0039] As shown in Figures 1-5, this embodiment provides a portable rope clamp for safety ropes, which includes the following main components:

[0040] Matching base 1: Two sets of symmetrically arranged bases, each with a lower input hole 301 at the bottom for the safety rope to pass through. The bases are fixed to the workbench surface with bolts to ensure overall stability.

[0041] Extension block 2: Fixed above the mating base 1, with a connecting guard plate on the inner side to enhance structural strength. Its external threaded hole can be connected to an external fixing device to further prevent the rope clamp from shifting.

[0042] Outer plate 3: Fixed inside the mating base 1, it has a hollow structure with an opening at the top for easy installation of the limiting wedge 5. The outer wall has a side output hole 302 for ropes to pass through. The edge of the outer plate 3 is provided with a pivot groove 101 and a mating groove 103. A locking shaft 102 passes through the pivot groove 101 to achieve coaxial mating of the two outer plates. The mating shaft 104, inserted into the mating groove 103, can fix the rotational position of the outer plate.

[0043] Operating handle 4: Installed on the outer wall of the outer cover plate 3, located directly above the expansion block 2. The opening and closing state of the outer cover plate 3 can be controlled by pushing or rotating the operating handle 4.

[0044] Limiting wedge 5: Embedded in the cavity of the outer jacket plate 3, including a main locking block 201, a rotating column frame 202, a rope guide groove 203, and an inner rope outlet hole 204. The top of the main locking block 201 is provided with a mating locking ring 205, which is in clearance fit with the limiting protrusion 401 on the inner wall of the outer jacket plate 3 to ensure that the limiting wedge 5 stably locks the rope when locked.

[0045] Example 2:

[0046] The operating steps for this rope clamp are as follows:

[0047] Rope insertion: The safety rope is inserted through the lower input hole 301 of the mating base 1, and then through the hole at the bottom of the limiting wedge 5 into the rope guide groove 203. Since the lower input hole 301 and the hole at the bottom of the limiting wedge 5 are the same size and coincident in position, there is no deviation after the rope is inserted.

[0048] Engaging and securing: Push the operating handle 4 to rotate the outer jacket plate 3 around the locking shaft 102. At this time, the mating groove 103 at the other end of the outer jacket plate 3 aligns with the mating shaft 104, and the mating shaft 104 is inserted to secure the outer jacket plate 3. During this process, the rotating column frame 202 of the limiting wedge 5 engages with the limiting protrusion 401 on the inner wall of the outer jacket plate 3, forcing the main engaging block 201 to press the rope downwards, completing the engagement.

[0049] Rope release: Pull out the engaging pin 104 and rotate the operating handle 4 in the opposite direction to open the outer cover plate 3. The limiting wedge 5 automatically resets under the separation action of the rotating column frame 202 and the limiting protrusion 401, releasing the compression on the rope and achieving rapid release.

[0050] Rope guide: After locking, the rope passes through the inner rope exit hole 204 above the rope guide groove 203 and is horizontally discharged through the side output hole 302 to ensure that the rope path is straight and avoid wear.

[0051] The portable rope catcher described in this embodiment achieves rapid locking and releasing of the safety rope through the linkage design of the limiting wedge 5 and the outer plate 3. Its compact structure and convenient operation make it suitable for high-altitude work equipment, rescue equipment, and other scenarios, significantly improving safety and work efficiency.
