Description

Technical Field

[0001] This utility model belongs to the field of hoisting tools, and in particular relates to an automatic unhooking device. Background Technology

[0002] Shackles are key connecting components in rigging, primarily used to connect ropes, slings, chains, and other lifting equipment to transfer force during the lifting of heavy objects. Shackles are widely used in equipment installation, machinery manufacturing, automobile manufacturing, aerospace manufacturing, shipbuilding, and other fields. Traditionally, after lifting operations are completed, workers need to climb to a height to manually remove the shackles. This requires workers to climb, and during such work, personnel safety conditions are often inadequate, increasing the risk of personal injury. For the lifting of tall storage tanks and towers, scaffolding needs to be erected after lifting to facilitate personnel access for shackle removal. Erecting scaffolding not only incurs additional installation costs but also delays the construction schedule. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes an automatic unhooking device with reasonable structural design, high safety, and the ability to automatically remove the unhooking hook at high altitudes, thereby improving the efficiency of hoisting operations.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] An automatic unhooking device, comprising:

[0006] The buckle body has a U-shaped structure, with two ends of the opening respectively provided with insertion hole A and insertion hole B, wherein insertion hole B is a threaded hole;

[0007] A pin, the right end of which is inserted into the insertion hole A and the insertion hole B, and the section inserted into the insertion hole B is provided with a matching external thread; the left end of the pin, the section not inserted into the buckle body, is a long rack structure; the left end face of the pin is connected to the rotating end of the rotating ring.

[0008] The unhooking mechanism includes a bracket located on the left side of the buckle body, a rotary drive device mounted on the bracket, a winch mechanism and a guide tube, and a pull rope with one end connected to the winch mechanism and the other end passing through the guide tube and connected to the fixed end of the rotating ring; the rotating end of the rotary drive device engages with the long rack structure of the pin to control the rotation of the pin.

[0009] The battery compartment is located on the right side of the buckle body, and integrates a remote control circuit board and a battery that powers the rotary drive device and the hoisting mechanism.

[0010] A distance sensor, mounted on the outside of the battery compartment, is used to monitor the position of the pin.

[0011] The remote controller is connected to the remote control circuit board and controls the operation of the rotary drive device and the hoisting mechanism; the distance sensor is connected to the remote controller.

[0012] The remote control circuit board is integrated in the battery compartment and connects to the remote controller via the 2.4G frequency band to control the rotary drive device and the hoisting mechanism. The remote controller can control the forward and reverse rotation of the rotary drive device and the hoisting mechanism. The rotation of the rotary drive device can drive the pin shaft into the socket B to complete the assembly with the buckle body, or it can drive the pin shaft out of the socket B to separate from the buckle body. The hoisting mechanism can pull the rope to pull the pin shaft out further, so that the sling inserted into the buckle body can be completely released, completing the unhooking operation. The position signal of the pin shaft returned by the distance sensor will be sent back to the remote controller, so that the operator can know the position of the pin shaft. The remote controller can be set with an indicator light. When the pin shaft reaches the designated position, the distance sensor will send an alarm signal back to the remote controller, and the indicator light on the remote controller will light up.

[0013] Furthermore, a limiting boss is provided on the outer wall of the pin shaft, and the limiting boss is located on the left side of the buckle body; the section of the pin shaft between the right end of the limiting boss and the insertion hole B with external thread is a smooth shaft structure, and the section of the pin shaft at the left end of the limiting boss is a long rack structure.

[0014] When assembling with the buckle body, the section of the pin with external threads is rotated and screwed into the threaded hole B of the buckle body under the drive of the motor, realizing a threaded connection. Compared with the structure of direct insertion, it is more stable and firm. During hoisting, the sling or sling is placed on the section of the pin with a smooth shaft structure. Compared with the structure where the entire pin is externally threaded, it is less likely to wear the sling or sling. The limiting boss plays a limiting role to prevent the pin from being completely pulled out and to limit the depth of screwing into the buckle hole B.

[0015] Furthermore, the bracket includes a horizontal support plate located above the pin, a vertical support plate connected at its upper end to the horizontal support plate, and a support tie rod located on the upper surface of the horizontal support plate; the right end of the horizontal support plate is fixed to the left side of the buckle body; the vertical support plate is provided with a through hole that does not affect the pin's passage; and the support tie rod supports the guide tube.

[0016] Furthermore, the rotary drive device includes a drive motor mounted on the horizontal support plate, a transmission gear connected to the output end of the drive motor, and symmetrical support gears located on both sides of the bottom of the pin shaft; the shafts of the transmission gear and the support gear are rotatably connected to the vertical support plate through shafts; the transmission gear and the support gear mesh with the long rack structure of the pin shaft.

[0017] The drive motor indirectly meshes with the long rack structure of the pin shaft through a transmission gear, causing the pin shaft to rotate; the support gear ensures effective meshing between the transmission wheel and the pin shaft, while also ensuring that the center position of the pin shaft does not change, facilitating the screwing of the pin shaft into or out of the threaded hole of the buckle body.

[0018] Furthermore, the battery is a replaceable dry cell battery or a button cell battery.

[0019] Furthermore, the weight of the unhooking mechanism and the battery compartment are balanced, and the buckle is in a balanced state after the pin is engaged in the buckle body.

[0020] Compared with the prior art, the automatic unhooking device of this utility model has the following advantages:

[0021] The automatic unhooking device of this utility model, through its reasonable structural design, enables remote-controlled automatic removal of the unhooking device at heights, completely avoiding the risks of working at heights and improving the efficiency of hoisting operations. A distance sensor monitors the pin position in real time, and in conjunction with the unhooking mechanism, it allows for precise unhooking by first rotating the pin back and then pulling it out. The rotary drive device has a reasonable structural design; through the transmission process of the drive motor, transmission gears, and the long rack structure of the pin, combined with the support gear, it ensures stable screwing in and out of the pin. The weight-balanced design on both sides of the buckle body prevents tilting during hoisting, improving safety. Attached Figure Description
