Definitions

  • ABSTRACT A release mechanism for use with relatively large chain, such as mooring chain of ships, drilling platforms and the like is disclosed which comprises an elongated cylindrical body having link portions integrally formed at opposite ends for connection to the chain.
  • the body of the mechanism has two disconnectable sections, each of which have a generally radially directed flange adjacent a circumferential line of disconnection.
  • a number of locking shoes bridge the line of disconnection, and each of them have a pair of generally opposed radial surfaces for engaging the flanges to hold the two sections together.
  • One end of each of the shoes has a rocker portion that curves radially inwardly relative to the side wall.
  • a concentric cam holds all of the locking shoes against the outer.
  • the present invention generally relates to automatic release mechanisms and, more particularly, to automatic release mechanisms for large chain or the like that are adapted for remote control actuation.
  • FIG. I is a plan view of the release mechanism embodying the present invention.
  • FIG. 2 is an end view of the mechanism shown in FIG. 1;
  • FIG. 3 is an enlarged plan view of the mechanism shown in FIG. 1 with portions removed to reveal the internal structure thereof and shown in its locked or armed configuration;
  • FIG. 4 is a view similar to FIG. 3, and illLsLatin mechanism immediately after actuation;
  • FIG. 5 is a cross section taken generally along the line 5-5 in FIG. 3;
  • FIG. 6 is a schematic diagram of the general hydraulic circuit utilized in the mechanism of the present invention.
  • FIG. 1 there is shown a release mechanism, indicated generally at 10, in conjunction with a large mooring chain 12 which is shown in phantom.
  • the release mechanism comprises 2 bodysections l4 and 16 which are separable or disconnectable along a line indicated at 18.
  • the sections 14 and 16 can separate from one another to relieve any load or tension that is placed upon the mechanism 10 and chain 12.
  • the release mechanism 10- can be activated by predetermined coded accoustic command signals, the receipt of which initiates a series of events which result in the body sections 14 and 16 being separated from one another to release the platform or the like which is anchored by the chain 12.
  • the hydraulic, electrical and movable structural elements that operate to release the mechanism are contained within the outer side walls of the cylindrically shaped mechanism and are therefore protected from physical abuse as well as the corrosive underwater environment in which the mechanism is intended to operate.
  • Each of the body sections 14 and 16, together with their respective link portions 20 are preferably integrally formed as unitary elements so that maximum strength is achieved.
  • the side walls of the body sections 14 and 16 may be several inches thick, and the mechanism 10 may approach 8 feet in overall length and may have a weight of about 6500 pounds so that it can achieve design breaking loads of up to a million pounds, for example. It should be understood that several chains and release mechanisms 10 with working loads of 300,000 pounds, for example, may be used to moor or anchor drilling platforms and other massive structures that may be used at sea.
  • the body sections 14 and 16 are preferably of unitary construction with the outer side walls providing the primary tension or load-bearing capability, a number of access plates 24, suitably attached by bolts 26, are provided to permit maintenance and the like of the internal components of the mechanism.
  • the plates preferably have gaskets (not shown) provided to make a watertight seal.
  • the body portion 16 has a watertight control compartment, indicated generally at 30, which houses electrical modules 32, hydraulic accumulators 34, hydraulic valving 36 and a hydraulic cylinder 38 and piston 40.
  • the electrical modules 32 include a receiver which is adapted to receive, amplify and decode an accoustic release command signal that is sent from a command transmitter.
  • the receiver is operably connected to the hydraulic accumulators and valve components of the mechanism so that the piston can be driven to cause the release of the mechanism in response to a release command signal being accoustically transmitted from a control station. It should be understood that the electrical and hydraulic components in the control compartment 30 are shown in schematic and idealized form.
  • each of the sections 14 and 16 is substantially increased in thickness immediately adjacent the line of disconnection 18. More specifically, the side walls of the sections 14 and 16 have an inwardly directed annular flanges 42 and 44, respectively, each'of which have respective angled surfaces 4-6 and 48. At the line of disconnection 18, the flange 44 has an annular tongue 50 that seats within a cooperatively configured groove 52 in the flange 42.
  • a number of locking shoes are provided, with the locking shoes 56 extending generally around the inside of the side walls of both the body sec-' tions 14 and 16 adjacent the line of disconnection. It should be understood that while only two of such locking shoes are shown in FIGS. 3 and 4 for the purpose of clarity of illustration, there are additional locking shoes utilized, such as shown in the cross section of FIG. wherein eight locking shoes are illustrated. While the number of locking shoes in and of itself is not critical there should be a sufficient number so that extraordinary stress is not focused on any particular locking shoe which may detrimentally affect the structural integrity of the mechanism as a whole.
  • the locking shoes 56 have a locking portion which comprises a pair of opposed angled surfaces 58 which are separated by a bridge'portion 60 and also includes a rocker portion 62 which is radially inwardly curved as shown.
  • the release mechanism is also provided with a central cam 64 which has a generally circular shape from the end view thereof, and which is inwardly curved laterally along the outer surface 66. When the mechanism is in its armed or locked position, shown in FIG. 3, it is seen that the cam 64 is in contact with the bridge portion 60 of all of the locking shoes 56 and, while in this position, the opposed angled surfaces 580i the locking portion engage the angled surfaces 46 and 48 of the flanges 42 and 44, respectively, and thereby lock the two body sec ons together.
  • a spring 39 may be provided in the connecting the piston to the cam 64, causes the locking shoes to become disengaged from the annular flanges 42 and 44 and permit separation of the body sections 14 and 16.
  • the rocker portion 62 of each of the locking shoes 56 also have one or more smaller recesses 72 therein for cooperative engagement with an annular retaining ring 74 which is attached to the side wall of the body section 16 so that the locking shoes are prohibited from sliding to the right when the cam is being moved in the same direction.
  • the only permitted movement of the locking shoes 56 is the rocking or pivoting movement wherein the rocker portion 62 is moved radially outwardly and the locking portion with the inclined surfaces 58 is moved radially inwardly.
  • the area in which the locking shoes and cam 64 are located be sealed from the control area by a wall 76 so that water will not enter the control area 30 after the sections have been separated.
  • an o-ring seal (not shown) or other sealing means is preferably provided around the shaft which extends from the compartment 30 so that water cannot enter the compartment between shaft and the wall 76.
  • a lubricating fluid such as oil 'or the like, may be provided within the area housing the locking shoes and cam to further protect the movable components from the corrosive effects of the underwater environment.
  • the locking shoes when the locking shoes are in the armed or locked position, they will be in contact with the surface of the outer walls of the body sections 14 and 16 and that during the pivoting movement caused by the cam 64, the left end portion shown in FIGS. 3 and 4 of the locking shoes 56 will be brought toward one another as shown in FIG. 4. Accordingly, it is preferred that the locking shoes be generally triangularly shaped as shown in FIG. 5 so that they can be moved radially inwardly without interfering with one another, particularly in the event a larger number of locking shoes are incorporated as shown for the eight locking shoes illustrated.
  • each of accumulators 34 has a soienoid valve 36 located within the hydraulic circuit that extends to the piston cylinder and conduits 80 downstream of each of the solenoid valves are combined in a single flow path. It is aiso preferred that a valve 82 be usedto provide a controlled leak within the system so that a leak.
  • valve 82 provides a slow acting control pressure bleeding function to prevent gradual build up of dangerous pressures within the conduit, but does not otherwise interfere with a sudden release of the high pressure fluid by the controlled actuation of the mechanism through a command signal generated by the transmitter at a control station or the like.
  • a remotely actuable release mechanism adapted to interconnect two portions of a chain or the like and to separate said portions from one another while under high tension, said mechanism being adapted for underwater use and comprising:
  • a body having two mating sections with each of the sections being connected to one of said chain portions so that separation of said body sections separates said chain portions;
  • movable locking means contained in one of said body sections and movable between a first position locking said body-sections together and a second position wherein said sections can be disconnected;
  • said actuating means including a control section contained within a watertight compartment and having electrical and hydraulic controls, said control section having piston means extending therefrom for moving said locking means from said first to said second position.
  • a release mechanism as defined in claim 1 including means for biasing said locking means in said first position.
  • a body comprising two mating sections disconnectable along a line of disconnection, the end of each section having securing means to which link means of the large chain or the like can be attached, each of said sections having a transverse inwardly extending flange adjacent the line of disconnection;
  • oneor more movable locking shoes having a locking portion bridging said flanges and line of disconnection, said locking shoes havingopposed surfaces for engaging said flanges, said shoes being adapted to prohibit disconnection of said sections when said opposed surfaces thereof are maintained in contact with said flanges;
  • each of said shoes having an inwardly curved rocker portion at one endthereof adapted to contact the side walls when moved radially outwardly, the outward movement of said rocker portion causing the locking portion to move radially inwardly and disengage the opposed surfaces of said locking portion from said flanges to thereby permit disconnection of said body sections;
  • cam means located adjacent said locking shoes and normallyholding said locking portion opposed surfaces in contact with said flanges, said cam means being adapted to contact and move said rocker portion radially outwardly and cause said locking portion to move away from said flanges and thereby permit separation of said sections;
  • a release mechanism as defined in claim 6 wherein a retaining ring is attached to said cylindrical side wall and cngageable with a recess of each of said locking shoes to prevent sliding movement of said shoes when said cam means is moved into contact therewith.
