[0029] A single-cable release device provided by the present invention, as Figures 1 to 3 shown, includes a release frame 1 and a release lever 2;

[0030] The release lever 2 includes a movable end 21 and a rotating end 22. The movable end 21 is hinged to the release frame 1, and an electric push rod 221 is rotatably connected to the rotating end 22 so that the electric push rod 221 drives the release lever 2 to rotate around the movable end 21 as the center;

[0031] The release lever 2 is rotatably connected with a connector 3. The connector 3 is fixedly connected with a release rod 31. The release rod 31 is slidably matched with the release frame 1. A release stop 32 is arranged at one end of the release rod 31 away from the release lever 2. The release frame 1 is rotatably connected with a rotating member 11. The rotating member 11 is movably abutted and matched with the release stop 32, and a hook 12 is arranged on the rotating member 11.

[0032] In this embodiment, when the device is in use, first, the hook 12 hooks the pulley shaft of the pulley 5. When release is required, the electric push rod 221 extends, driving the release lever 2 to rotate around the movable end 21 as the center. The joint 3 drives the release rod 31 to move to the right, and the release baffle moves to the right accordingly. At this time, the release baffle releases the restriction on the rotating member 11. The rotating member 11 rotates under the action of its own gravity, causing the pulley 5 to unhook and slide, and the release is completed. Then, the electric push rod 221 contracts, the release baffle moves to the left, the rotating member 11 returns to its original position, and after the pulley 5 returns, it hangs on the hook 12 to hook the pulley 5.

[0033] In this embodiment, the release frame 1 includes a fixing part 13 and a mounting part 14. The mounting part 14 is fixedly connected to the end face of the fixing part 13 away from the cableway. The movable end 21 is hinged to the fixing part 13. The joint 3 is in telescopic sliding fit with the mounting part 14. In this embodiment, the joint 3 is a U-shaped joint 3. The joint 3 is hinged to the release lever 2 to achieve its rotatable connection with the release lever 2. The hinge point between the joint 3 and the release lever 2 is located between the movable end 21 and the rotating end 22.

[0034] In this embodiment, a support frame 141 is provided on the top end face of the mounting part 14. The electric push rod 221 is hinged to the support frame 141. Based on the top end face of the mounting part 14, the hinge point between the electric push rod 221 and the support frame 141 is higher than the hinge point between the electric push rod 221 and the connecting frame, so that the electric push rod 221 is in an inclined state.

[0035] In this embodiment, the mounting part 14 includes a mounting cavity 142. The release rod 31 slides telescopically along the mounting cavity 142. The mounting cavity 142 provides a stable sliding environment for the release rod 31, which can enhance the reliability of the device. The end face of the mounting part 14 facing the pulley 5 is provided with a first opening 1421 corresponding to the rotating member 11 to ensure that when the release block 32 releases the restriction on the rotating member 11, the rotating member 11 can rotate smoothly, so as to realize the unhooking and sliding of the pulley 5. It should be noted that due to the length of the rotating member 11, in order to ensure that when the release block 32 releases the restriction on the rotating member 11, the rotating member 11 can rotate smoothly, a second opening 1422 is provided on the end face of the mounting part 14 away from the pulley 5. In other embodiments, the second opening 1422 can be selected to be provided or not according to the use environment.

[0036] In this embodiment, the release block 32 is set in an L-shaped structure for supporting the rotating member 11. A buffer part 111 is provided at one end of the rotating member 11 facing the release block 32. The buffer part 111 is formed on the end face of the rotating member 11 facing the first opening 1421. The width of the rotating member 11 gradually decreases along the side facing the release block 32 to form the buffer part 111, which can effectively slow down the rotation speed of the rotating member 11 and play a buffering role.

[0037] In this embodiment, a connecting shaft 1423 is provided in the installation cavity 142. The rotating member 11 is rotatably installed on the installation portion 14 through the connecting shaft 1423. In other embodiments, in order to enable the rotation of the rotating member 11, the connecting shaft 1423 can be close to the side away from the release baffle, or a counterweight is provided on the side of the rotating member 11 facing the baffle, so that after the release block 32 moves to the right, the support restriction on the rotating member 11 is released, and the rotating member 11 can rotate clockwise under the action of its own gravity.

[0038] In this embodiment, a pull rod 23 is provided on the release lever 2, and an elastic member 311 is sleeved on the outer wall of the release rod 31. The elastic member 311 is in abutting fit between the block and the inner wall of the installation cavity 142. When a power failure occurs and the electric push rod 221 cannot operate, the pull rod 23 can be manually moved to move the release rod 31 to the right to complete the release. Then, under the action of the spring, the hook 12 assembly resets, and other operations are the same as those of the electric one.

[0039] In this embodiment, the device further includes a trolley fixing device 4. The trolley fixing device 4 includes a fixing plate 41. The fixing plate 41 is provided with a limiting groove 42 and a wire rope clip 43. The wire rope clip 43 passes through the fixing plate 41 and is fixed on the wire rope. The trolley 5 is in fitting engagement with the limiting groove 42. When the trolley 5 returns, the trolley fixing device 4 can effectively increase the stability of the trolley 5, so that the trolley 5 maintains a stable state and is easy to hang on the hook 12 to hook the trolley 5. It should be noted that the cooperation of the wire rope clip 43 with the fixing plate 41 and the wire rope on the trolley fixing device 4 is a prior art, and those skilled in the art should be clear about its structure, principle, usage method, etc., and will not be specifically described here.

[0040] A single-cable release device provided by the present utility model is mainly used for the release of a trolley 5 sliding on a single rope. The electric push rod 221 is used to realize the automatic operation of release and hooking of the hook 12, reducing manual intervention, effectively improving work efficiency, and the device uses the lever principle to achieve force transmission, with a compact structure, easy to install and maintain, and stronger practicability.
