Specific embodiments

[0023] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and the description are illustrative in nature and are not used to limit the protection scope of the claims.

[0024] As Figures 1 to 8 collectively shown, the remotely controlled automatic disassembly sling includes a U-shaped sling body. The two booms 1 of the U-shaped sling body are arranged in parallel at intervals. Through holes are provided at the free ends of the booms 1, and a pin shaft 2 is movably installed through the two through holes. A control box body is detachably installed on one side of the U-shaped sling body. A driving device for controlling the telescoping of the pin shaft 2 is installed in the control box body. The driving device is connected to a power supply assembly 5 and a control device. When the pin shaft 2 extends, the U-shaped sling body is in a locked state. When the pin retracts, the U-shaped sling body is in an open state. The present utility model controls the driving device through the control device for the automatic disassembly of the sling. The driving device drives the pin shaft 2 to telescope to automatically open or lock the sling, eliminating the need for workers to climb to high places to manually disassemble the sling, solving the safety hazard problems existing in the prior art, better meeting the needs of customers, having wide applicability and excellent technical effects, and having high practical value and safety benefits.

[0025] As Figures 1 to 8 collectively shown, a counterweight 6 is detachably installed on the other side of the U-shaped sling body. The weight of the counterweight 6 is adapted to the weight of the control box body. The counterweight 6 is used to balance the weight of the control box body, so that the weights on both sides of the U-shaped sling body are kept consistent, maintaining the balance of the U-shaped sling body.

[0026] As Figures 2 to 5As shown together, the driving device is a linear rack reduction motor 4. The linear rack 41 passes through the central through-hole of the motor. When the motor works, it drives the linear rack 41 to reciprocate telescopically. The linear rack reduction motor 4 is a prior art. When it works, it makes the linear rack 41 reciprocate telescopically, and then drives the telescopic movement of the pin shaft 2 to realize the opening and locking of the U-shaped hanging ring body.

[0027] As Figure 1 and Figure 2 As shown together, the control box body includes a U-shaped frame 31 and a housing 32 detachably wrapped on the U-shaped frame 31. At both ends of the U-shaped frame 31, limiting holes 33 are relatively arranged. Both ends of the linear rack 41 are slidably installed in their respective corresponding limiting holes 33. One end of the linear rack 41 passes through the limiting hole 33 and is fixedly connected to the pin shaft 2. The U-shaped frame 31 is the main support frame for installing various internal components. The housing 32 is preferably a U-shaped housing 32, which wraps the three exposed surfaces of the U-shaped frame 31 and forms a detachable box body together with the U-shaped frame 31. The control box body protects its internal structure from being bumped and affected by bad weather such as wind, rain and so on. The limiting holes 33 limit the linear rack 41 to keep its advancing direction consistent with the axis all the time and prevent shaking.

[0028] As Figures 3 to 5 As shown together, a limiting ring 7 is installed at the connection between the linear rack 41 and the pin shaft 2. The limiting ring 7 is located inside the U-shaped frame 31. When the limiting ring 7 fits with the inner wall of the U-shaped frame 31, it plays a role in restricting the excessive extension of the pin shaft 2. When the limiting ring 7 fits with the linear rack reduction motor 4, it plays a role in restricting the excessive retraction of the pin shaft 2.

[0029] As Figure 1 and Figure 2 As shown together, a camera 8 is installed on the outer side wall of the control box body. The camera 8 faces the U-shaped hanging ring body, and the camera 8 is connected to the control device. The camera 8 facing the U-shaped hanging ring body can enable remote operators to observe the opening and closing state of the U-shaped hanging ring body, which is convenient for timely intervention.

[0030] As Figure 4 and Figure 5 As shown together, the counterweight 6 is detachably installed on one of the lifting arms 1 through a first stainless steel fixed pipe clamp 91; the control box body is detachably installed on the other lifting arm 1 through a second stainless steel fixed pipe clamp 92. The first stainless steel fixed pipe clamp 91 and the second stainless steel fixed pipe clamp 92 have the same structure and are very convenient for detachable connection.

[0031] The power supply assembly 5 in the present utility model is preferably a large-capacity lithium battery.

[0032] In this application, for the technical features related to software and circuit programs, the implementation of their functions belongs to the prior art. The essence of the technical solution of this application is the improvement of the composition and connection relationship of the hardware part, and does not involve the improvement of the software program or the circuit structure itself.

[0033] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0034] Only some exemplary embodiments of the present utility model have been described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
