Embodiment Construction

[0011] With reference to the accompanying drawings, figure 2 Among them, the hook is welded on the tapered seat, and the hanging head 4 can rotate freely around the axis 8. The positional relationship between the length of the lower part of the hanging head 4 and the semi-cylindrical axis 2 is: when the plane of the semi-cylindrical axis 2 is horizontal, the hanging head 4 It can pass freely; when the plane of the semi-cylindrical shaft 2 was vertical, the lower part of the suspension head 4 would be stuck. When in use, turn the suspension head 4 to figure 2 In the position shown, the baffle plate 7 is lifted up, and the baffle plate 7 drives the semi-cylindrical shaft 2 to rotate, so that the plane of the semi-cylindrical shaft 2 is vertical, and the baffle plate 7 is locked in the vertical position by the safety pin 6. The role of the cylindrical shaft 2 and the stop pin 5, the suspension head 4 is stuck and locked in the figure 2 position, then you can hang the ring on...

Abstract

The invention relates to a quick release mechanism for a crane. The quick release mechanism consists of a hanging seat and a hanging ring, wherein a steel wire rope and the hanging ring are cast into a whole, and the hosting ring can freely rotate around the axis of the steel wire rope; a hanging hook and a conical seat are connected together and fixed on a skiff, a hanging head on the hanging hook can freely rotate around an axis vertical to the steel wire rope, and a safety pin, a baffle plate and a semicylindrical shaft are jointly acted to control the position and the action of the hanging head, therefore rapid hook hanging and hook release are realized.

Description

(1) Technical field [0001] The invention relates to a device installed on small boats equipped for ships and offshore working platforms for crew emergency escape and daily work, which belongs to the shipbuilding technology, and specifically relates to a crane release hanger ring, which has the following characteristics: Quick hook and unhook function. (2) Background technology [0002] In the case of high sea conditions and speed boat release, fast and safe hooking and unhooking is an important condition to ensure the safety of small boats and people on board. At present, the domestic hooks basically cannot realize fast hooking and unhooking when the speed is received and the boat is released, which limits the speed of the boat. (3) Contents of the invention [0003] In order to solve the above-mentioned limitations, the present invention designs a novel crane quick release hanger ring to realize fast hooking and unhooking. figure 1 It is a schematic diagram of the coord...
