[0001] The present application relates to the technical field of decoupling devices, and in particular to a decoupling device. Background Art

[0002] A decoupler is a device that automatically unhooks cargo during lifting. It typically consists of a hook, a sliding hook, a compression spring, a handle, and a main frame. It's primarily used in lifting operations and automatically unhooks cargo once it reaches a predetermined position, streamlining operations and improving efficiency.

[0003] Some existing decoupling devices require manual decoupling operations, which is laborious and reduces work efficiency, and there is room for improvement. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a decoupling device that can automatically open and close the decoupling device through the electric cylinder drive control, avoiding manual opening and closing operations of the decoupling device, saving manpower, and improving work efficiency. At the same time, it can protect the electric cylinder, avoid easy damage to the electric cylinder, and extend the service life of the electric cylinder. It solves the problem that some existing decoupling devices require manual decoupling operations, which is more laborious, reduces work efficiency, and has room for improvement.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a decoupling device, comprising a connecting rod, the outer circumference of the connecting rod is rotatably connected to a first hook, the outer circumference of the connecting rod is rotatably connected to a second hook, the upper surface of the first hook is fixedly connected to a fixing plate, the front face of the fixing plate is fixedly connected to an electric cylinder, the interior of the electric cylinder is slidably connected to an output shaft, the end of the output shaft away from the electric cylinder is fixedly plugged with a sliding rod, a sliding groove is provided at the top of the second hook, the outer circumference of the sliding rod is slidably connected to the second hook through the sliding groove, the front face of the fixing plate is fixedly connected to a protective cover, and the interior of the protective cover is slidably connected to a cover door.

[0006] Through the above scheme, since some existing unhooking devices require manual unhooking operations, which is more laborious and reduces work efficiency, there is room for improvement. By providing a sliding rod that moves horizontally with the electric cylinder as the power, and a sliding groove that is adapted to the sliding rod at the top of the second hook, the sliding rod can drive the second hook to rotate and open and close when it moves, avoiding manual opening and closing operations of the unhooking device, saving manpower and improving work efficiency. By providing a protective cover and a cover door on the outside of the electric cylinder, the electric cylinder is protected, avoiding easy damage to the electric cylinder and extending the service life of the electric cylinder.

[0007] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the sliding rod, and the outer surface of the limiting ring is slidably connected to the second hook through a slot provided inside the second hook.

[0008] Through the above solution, the sliding rod is restricted to prevent the sliding rod from easily falling out of the sliding groove, thereby improving the stability of the sliding rod movement.

[0009] Furthermore, a heat dissipation plate is provided inside the cover door, and heat dissipation holes arranged at equal intervals are opened inside the heat dissipation plate.

[0010] Through the above solution, the heat generated during the operation of the electric cylinder in the protective cover can be discharged through the heat dissipation holes on the heat dissipation plate, thereby avoiding heat accumulation inside the protective cover and damage to the electric cylinder.

[0011] Furthermore, a push plate is fixedly connected to the front of the cover door.

[0012] Through the above solution, the cover door can be pushed and pulled to open and close by the push plate, which provides convenience for the user. At the same time, the push plate can also restrict the cover door to prevent the cover door from easily falling off from the inside of the protective cover.

[0013] Furthermore, an observation window is fixedly connected to the top of the protective cover, and the observation window is made of transparent material.

[0014] Through the above solution, the working status of the electric cylinder in the protective cover can be observed through the observation window made of transparent material, which provides convenience for the user.

[0015] Furthermore, a mounting plate is fixedly connected to the upper surface of the fixing plate, and mounting holes arranged at equal intervals are provided inside the mounting plate.

[0016] According to the above solution, the decoupler can be mounted on the external device by using bolts through the mounting holes on the mounting plate, which facilitates the installation of the decoupler.

[0017] Furthermore, the protective cover is fixedly connected to the fixing plate by bolts, and the cover door is fixedly connected to the protective cover by bolts.

[0018] Through the above solution, bolts are used to connect and fix the protective cover and the fixing plate, which facilitates the installation and disassembly of the protective cover. Bolts are used to connect and fix the cover door and the protective cover to prevent the cover door from being easily opened, thereby improving the stability of the cover door.

[0019] Furthermore, a notch is formed at one end of the protective cover close to the output shaft, and the notch corresponds to the position of the output shaft.

[0020] Through the above solution, the notch can prevent the protective cover from being obstructed by the output shaft during installation and removal, thereby enabling the protective cover to be installed and removed smoothly.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The unhooking device is configured to have a sliding rod on the first hook that is powered by an electric cylinder and moves laterally, and a sliding groove at the top of the second hook that is adapted to the sliding rod, so that the sliding rod can drive the second hook to rotate and open and close when it moves, thereby avoiding manual opening and closing operations of the unhooking device, saving manpower, and improving working efficiency. A protective cover and a cover door are provided on the outside of the electric cylinder to protect the electric cylinder, thereby avoiding easy damage to the electric cylinder and extending the service life of the electric cylinder. This solves the problem that manual opening and closing operations of the unhooking device are relatively laborious and the relatively precise electric cylinder is easily damaged during operation.
