Rocker slider mechanism quick release device

Abstract

The invention discloses a quick unhooking device with a rocker sliding block mechanism. The quick unhooking device comprises a parent plate, a left clamping hook, a right clamping hook, a left swing arm, a right swing arm, a driving device, a locking spring and a controller. The left clamping hook and the right clamping hook are symmetrically arranged on the left side and the right side of the parent plate through a pin shaft b. One end of the left swing arm and one end of the right swing arm are hinged to the left clamping hook and the right clamping hook correspondingly, and the other end of the left swing arm and the other end of the right swing arm are arranged in a sliding groove of the parent plate through a pin shaft c. The parent plate, the left clamping hook, the right clamping hook, the left swing arm, the right swing arm and the pin shaft c form the rocker sliding block four-connecting rod mechanism in a hinged mode. The locking spring is connected with a lower spring connecting shaft on the parent plate and an upper spring connecting shaft of the pin shaft c. The driving device is connected with the pin shaft c in a driving mode. According to the quick unhooking device with the rocker sliding block mechanism, the safe opening and closing functions and the automatic locking function of the unhooking device are achieved, and the safety performance in the heavy object lifting process is enhanced; moreover, quick unhooking is achieved under the gravity effect of lifted heavy objects, and the purposes of quickness and high efficiency are achieved.

Description

technical field [0001] The invention relates to a quick decoupling device for lifting heavy objects and sudden unloading under load, which is applied to occasions such as high-altitude throwing in some civil engineering and mechanical engineering, and specifically relates to a quick decoupling device for a rocker slider mechanism. Background technique [0002] Most of the fast uncoupling devices in the market are complex in structure, and the decoupling and hooking functions are realized by pulling the uncoupling rods with manual ropes, which cannot reach the fast and safe uncoupling and hooking functions. Contents of the invention [0003] The purpose of the present invention is to solve the problems of complex structure and low safety of the quick uncoupling device in the prior art, and provide a fast and high-safety fast uncoupling device for the rocker slider mechanism. The device is compact in structure, safe and reliable, practical and convenient , can realize liftin...
