Embodiment 2
[0032] The lowermost end of the first pliers arm 6 includes a first upper assembly surface 61 and a first lower assembly surface 62, and the first upper assembly surface 61 and the first lower assembly surface 62 face the center line of the contact surface respectively. Folding, the lowermost end of the second pliers arm 7 includes a second upper assembly surface 71 and a second lower assembly surface 72, and the second upper assembly surface 71 and the second lower assembly surface 72 face the contact surface respectively. The midline is gathered.
[0033]The first upper assembly surface 61 and the second upper assembly surface 71 refer to the contact surface between the object to be transported and the lifting ring when the object to be transported is detached from the lifting tongs, and the object to be transported is on the first upper assembly surface. The assembly surface 61 and the second upper assembly surface 71 form a V shape, so that the object to be transported can...

The invention discloses an automatic unhooking device and a lifting appliance. The automatic unhooking device comprises a worm gear, a worm and a motor used for driving the worm to rotate, wherein the worm gear is meshed with the worm; the automatic unhooking device also comprises a cam, a locking lever, a lifting hanging clamp, a first elastic part and a second elastic part, wherein the cam is fixedly connected with the worm gear; one end of the locking lever is matched with the cam, and the other end of the locking lever is provided with a hook-shaped bulge; the locking lever is provided with a rotating hole; the lifting hanging clamp comprises a first clamp arm and a second clamp arm which are articulated with each other by a fixed shaft; the upper end of the first clamp arm is rotatably matched with a rotary pin shaft; the lower end of the first clamp arm can be in contact with the lower end of the second clamp arm; the contact surface between the first clamp arm and the second clamp arm is positioned at the lowest point; the first elastic part is arranged above the end of the hook-shaped bulge of the locking lever; the second elastic part is arranged under the end of a matching bulge of the second clamp arm. The lifting appliance comprises the automatic unhooking device. The automatic unhooking device and the lifting appliance eliminate the potential safety hazard and improve the working efficiency.
Description
technical field [0001] The invention relates to the lifting industry, in particular to an automatic decoupling device. Background technique [0002] The uncoupling device is frequently used equipment in the lifting industry. The existing decoupling device is a human-intervention hook. However, this kind of decoupling device has a large safety hazard when used, and the efficiency is very low during work. [0003] Therefore, need to invent a kind of novel automatic decoupler. Utility model content [0004] The main purpose of the present invention is to provide a novel automatic decoupling device, so that the automatic decoupling of the lifting equipment can be realized. [0005] The purpose of the present invention and the technical problem solved are realized by adopting the following technical solutions. [0006] Through an automatic decoupling device, it includes a worm wheel, a worm and a motor, the motor drives the worm to rotate, the worm meshes with the worm, and a...
