Description

Technical Field

[0001] This utility model relates to the field of unhooking device technology, and in particular to a pin-type electric automatic unhooking device. Background Technology

[0002] As a critical safety device, the unhooking device is widely used in lifting machinery, ship loading and unloading, and engineering equipment to achieve rapid connection and release of loads. Traditional unhooking devices mostly rely on manual operation, using mechanical levers or hydraulic mechanisms to achieve the unhooking function. However, in complex or high-risk operating environments, manual operation suffers from low efficiency, slow response speed, and safety hazards, making it difficult to meet the needs of modern industrial automation and intelligence.

[0003] Therefore, there is an urgent need for a compact and efficient electric automatic unhooking device to improve the accuracy, reliability and safety of the unhooking action and meet the needs of automated operation under complex working conditions. Utility Model Content

[0004] The purpose of this utility model is to provide a pin-type electric automatic unhooking device to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides a pin-type electric automatic unhooking device, including an unhooking device body, a first housing, a second housing, and a lifting shaft. The first housing and the second housing are respectively disposed on both sides of the unhooking device body. A shackle is disposed on the top of the unhooking device body, and the shackle is connected to the unhooking device body by bolts and fixing nuts.

[0006] The first housing contains a drive component, a sleeve, and a ball screw. The motor is fixedly connected to the unhooking device body via a support frame. The ball screw is located inside the sleeve and is fixed to the unhooking device body via the sleeve. The lifting shaft is connected to the nut support on the ball screw.

[0007] Preferably, the driving component is a motor, the output end of the motor is fixedly connected to a first gear, and the end of the ball screw away from the nut support is fixedly connected to a second gear. The first gear and the second gear are connected by chain drive.

[0008] Preferably, the sleeve and the ball screw are rotatably connected via bearings.

[0009] Preferably, the second housing is provided with an electronic control device and a power display device inside. The electronic control device is fixed on the inner side wall of the second housing, and the power display device is located at the inner top of the second housing.

[0010] Preferably, the front side of the second housing is provided with a switch button, an open button and a close button, and the rear side is provided with a close position indicator button and an open position indicator button.

[0011] Preferably, the bottom of the unhooking device body is provided with a sliding groove, the lifting shaft is disposed inside the sliding groove, and the lifting shaft is slidably connected to the sliding groove.

[0012] Preferably, the sleeve is provided with a limiting groove, the nut support is provided with a limiting post, and the limiting post is slidably connected to the limiting groove.

[0013] Preferably, the lifting shaft has an internal cavity.

[0014] Preferably, the electronic control device is equipped with a remote control receiver module, which is wirelessly connected to a remote controller.

[0015] Therefore, the present invention provides a pin-type electric automatic unhooking device with the following beneficial effects: the present invention drives the first gear to rotate through a motor, the first gear drives the second gear to rotate through a chain, and then drives the ball screw to rotate. The ball screw converts the rotational motion into the linear motion of the hanging shaft, realizing the automation of the unhooking action, significantly improving the operating efficiency and response speed, and is especially suitable for work scenarios that require rapid release.

[0016] By employing ball screw transmission, the transmission efficiency is high and the precision is stable, ensuring accurate control of the unhooking action. The ball screw transmission has a self-locking characteristic to prevent accidental release of the load and enhance the reliability of the equipment. By setting limit grooves and limit columns, the stability of the linear movement of the lifting shaft is ensured, while preventing the movement of the lifting shaft from exceeding the safe range, thus improving the safety of the equipment.

[0017] By integrating the drive and transmission inside the first housing and the electronic control device inside the second housing, the layout is compact and highly protective, making it suitable for confined spaces or harsh working conditions. Attached Figure Description
