Mechanical automatic butt-joint releasing device

Abstract

The invention relates to a mechanical automatic butting and releasing device, which comprises a drop hanger part and a hanger rod part. The drop hanger part comprises a cylindrical drop hanger body of which an upper end flange is connected with a lifting wire rope through a wire rope joint, and the interior of a lower end flange is provided with at least two shaft pin sliding bushes on the same axial cross section along the radial direction. A spring shaft pin which can flex under the action of a compression spring is arranged in each of the shaft pin sliding bushes; and the hanger rod part comprises a step cylindrical hanger rod body of which the top end is provided with a hanger rod head capable of sliding along the inner wall of the drop hanger body and matching the front end of the spring shaft pin in a blocking mode. A releasing sliding ring which can slide axially along the hanger rod body is arranged between the hanger rod head and steps of the hanger rod body. The upper ring surface and the lower ring surface of the releasing sliding ring are matched with the shapes of the front ends of the spring shaft pins so that the releasing sliding ring can press the spring shaft pins into the shaft pin sliding bushes when the releasing sliding ring passes through the spring shaft pins. The bottom end of the hanger rod body is provided with a clamping device for connecting a hung device. The mechanical automatic butting and releasing device uses a pure mechanical structure to effectively realize the automatic butting and releasing of an underwater operating device.

Description

technical field [0001] The invention relates to a hoisting recovery mechanism for submersibles and other underwater operating equipment with flexible connections, in particular to a mechanical automatic docking release device. Background technique [0002] With the continuous development of marine resources, underwater operation equipment such as submersibles are more and more widely used. One of the common characteristics of these equipment is that there is a long flexible umbilical cable connected with the power and control equipment on the mother ship. connect. Before the equipment is operated in the ocean, it must first be hoisted from the ship deck to the horizontal level through the special hoisting equipment on the mother ship, and then the hoisting equipment must be disengaged, and the submersible and other underwater equipment can perform deep sea operations by themselves; after the operation is completed, First of all, it is necessary to dock the hoisting equipmen...
