[0005] In order to solve the above technical problem, the navigation mark operation crane automatic unhooking device of the utility model, including hanging component, connecting component, limiting component and hoisting component, the connecting component includes a pair of upper end through hinged shaft one hinged on the hanging component connection arm one and connection arm two, the hoisting component includes lifting arm one and lifting arm two, the lower end of the connection arm and the upper end of the lifting arm one are hinged at hinged shaft two, the lower end of the connection arm two and the upper end of the lifting arm two are hinged at hinged shaft three, the middle part of the lifting arm one and the middle part of the lifting arm two are mutually crossed and hinged at hinged shaft four, the lower end of the lifting arm and the lower end of the lifting arm two form clamping part, the limiting component is the rod-like structure that one end is hinged on the hinged shaft two and is located between the connection arm one and the lifting arm one, the other end of the limiting component is placed above the hinged shaft three by gravity, and can move with the change of device working state, limiting block is arranged on the limiting component, when clamping part gradually opens so that the limiting block falls between the hinged shaft two and the hinged shaft three, it can play the limiting effect.
[0006] The connection arm one and the connection arm two are respectively formed by a pair of arms that are symmetrical relative to the hanging component.
[0007] The lifting arm one and the lifting arm two are respectively formed by a pair of arms that are symmetrical relative to the hanging component.
[0008] The fastening block is arranged between the lower end supporting arms of the first hoisting arm and the second hoisting arm respectively.
[0009] The limiting part is provided with a rope hole.
[0010] The device is convenient to open and close. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 2 It is a perspective view of the device in a closed state. DETAILED DESCRIPTION
[0013] The automatic unhooking device of the navigation beacon operation crane will be further described in detail in combination with the drawings and specific embodiments.
[0014] As shown in the drawings, the automatic unhooking device of the navigation beacon operation crane comprises a hanging part 1, a connecting part 2, a limiting part 3 and a hoisting part 4. The connecting part 2 comprises a pair of connecting arms 5 and 6 which are hingedly connected to the hanging part 1 through a hinging shaft 12 at the upper end.
[0015] The hoisting part 4 comprises a first hoisting arm 7 and a second hoisting arm 8. The lower end of the connecting arm 5 and the upper end of the first hoisting arm 7 are hingedly connected at a hinging shaft 13, the lower end of the connecting arm 6 and the upper end of the second hoisting arm 8 are hingedly connected at a hinging shaft 14, and the middle part of the first hoisting arm 7 and the middle part of the second hoisting arm 8 are hingedly connected at a hinging shaft 15. The lower end of the first hoisting arm 7 and the lower end of the second hoisting arm 8 jointly form a clamping part.
[0016] The limiting part 3 is a rod-shaped structure which is hingedly connected to the hinging shaft 13 at one end and located between the connecting arm 5 and the first hoisting arm 7. The other end of the limiting part 3 is supported above the hinging shaft 14 by gravity and can move with the change of the working state of the device, and a rope hole 10 is formed in the limiting part 3. A limiting block 9 is arranged on the limiting part 3, and when the clamping part is gradually opened and the limiting block 9 falls between the hinging shaft 13 and the hinging shaft 14, the limiting effect is achieved.
[0017] The connecting arm 5, the connecting arm 6, the first hoisting arm 7 and the second hoisting arm 8 are respectively composed of a pair of supporting arms which are symmetrical with respect to the hanging part 1. Fastening blocks 11 are arranged between the lower end supporting arms of the first hoisting arm 7 and the second hoisting arm 8 respectively to connect them as a whole.
[0018] In use, since the default state of the device when not in use is the open state, first hoist the device above the weight to be hoisted, so that the lifting ring of the weight is in the space of the clamping part formed by the lower ends of the first lifting arm 7 and the second lifting arm 8, then pull the rope through the rope hole 10, lift the limiting part 3, so that the limiting block 9 is disengaged from between the second hinge shaft 13 and the third hinge shaft 14, under the action of gravity, the angle between the first connecting arm 5 and the second connecting arm 6 gradually decreases, so that the clamping part is closed, and the hoisting operation can be performed. When lowering, after the hoisted object contacts the ground, the hanging part 1 continues to be pressed down, the angle between the first connecting arm 5 and the second connecting arm 6 gradually increases, so that the clamping part is opened and unhooked, and the opening angle gradually increases, until the limiting part 3 falls down, and the limiting block 9 is re-engaged into between the second hinge shaft 13 and the third hinge shaft 14 to complete the limiting.
[0019] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
