Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Since the short hanger and the long hanger contain the same components, the short hanger is used as an example to describe the structure. figure 1 As shown, the components are as follows: hook 1, rope 2, suspension ring 3, sonar scanning instrument 4, sealing box 5, hydraulic cylinder part 6, push rod sliding bracket 7, push rod 8. A sealed hydraulic station is installed in the sealed box 5, and the hydraulic cylinder part 6 is driven through the corresponding pipeline; the piston 18 of the hydraulic cylinder is connected with the push rod 8 through threads, so that the push rod 8 can make a straight line through several push rod sliding brackets 7 Reciprocating motion; there are ropes 2 corresponding to the number of hooks on the push rod 8, and the push rod 8 pulls the ropes 2 to untie the ropes, so that the hook 1 can be aut...

Abstract

The invention provides a submarine pipeline press cake release combined hanging bracket. The submarine pipeline press cake release combined hanging bracket mainly comprises a long hanging bracket body, a short hanging bracket body, an outer source unhooking type hanging hook, a hydraulic system and a sonar imaging system. According to different task environments, the long hanging bracket body and the short hanging bracket body can be riveted and jointed through bolts, and the aim of variable structure press cake hanging work is achieved. The hook on the hanging bracket has the functions of loading and automatically releasing press cakes, and the press cakes are used for protecting submarine pipelines. A hydraulic drive manner is used for press cake unhooking on the hanging bracket, and transportation of the hanging bracket is completed under submarine oil pipe position imaging, observing and positioning through the sonar system. By means of the hanging bracket, the press cakes can be loaded and released, and are used for protecting the submarine pipelines. The hydraulic drive manner is used for press cake unhooking on the hanging bracket, so that safety and reliability are achieved.

Description

technical field [0001] The invention relates to a submarine pipeline press block releasing combined hanger, in particular to a submarine pipeline pressing block releasing combined hanger. Background technique [0002] The traditional briquette release hanger uses divers to dive to the bottom of the sea to complete the positioning of the submarine pipeline; after the briquettes are transported to the release position under the instructions of the divers, the divers cut each rope to complete the release of the briquettes. Work efficiency is low and there is certain danger. In waters with a depth of more than 200 meters, due to the limitation of divers' ability, the underwater robot can only remove the hooks one by one to release the cement briquettes, and the cost is too high. In addition, the traditional hanger has no way to adapt to the working conditions to improve the efficiency of long straight pipelines and curved pipelines. In order to solve these problems, the presen...
