Description

  The present invention relates to a fluid handling apparatus having two fluid handling pipes. Each fluid handling pipe is provided with an emergency detachment device, and each fluid handling pipe is overloaded during fluid handling and is likely to be damaged. Further, the present invention relates to a fluid handling apparatus configured such that each emergency release device is activated and separated, and each fluid handling tube is divided into one side of the cargo handling and the other side of the cargo handling.

  For example, a fluid handling device used when handling various fluids such as liquefied propane gas and liquefied natural gas between a land-based fluid storage facility on one side of cargo handling and a tanker on the sea on the other side of cargo handling is used for strong winds and storm surges. In order to prevent an unloading of the fluid handling pipe over the land side and the sea side due to unexpected movement of the tanker due to tsunami etc. In order to prevent the situation from spreading to the other side through the fluid handling pipe when an unexpected situation such as a fire occurs on the land side or the sea side, the flow of fluid has been interrupted quickly in the event of an emergency. Then, after ensuring the prevention of fluid outflow, an emergency detachment device is provided in the middle of the fluid handling pipe to divide the fluid handling pipe into the land side and the sea side.

  In addition, the fluid handling apparatus includes, for example, two fluid handling pipes, a first fluid handling pipe for handling liquefied gas (liquid fluid) and a second fluid handling pipe for handling vaporized gas (gaseous fluid). Some of them are equipped with a fluid handling tube. In an emergency, such a fluid handling device can be used in the event of an emergency, even if either the first fluid handling tube or the second fluid handling tube can be disconnected. Since the whole fluid handling apparatus cannot be divided unless it is possible, both of the fluid handling pipes must be divided. Therefore, conventionally, a fluid handling apparatus provided with such two fluid handling pipes has each fluid handling pipe. Each is provided with an emergency detachment device.

  More specifically, conventionally, such a fluid handling device is, for example, attached to (attached to) the first fluid handling tube and the movement of the first fluid handling tube. When two fluid handling pipes of the moving second fluid handling pipe are provided and the fluid cargo handling pipe needs to be urgently detached, each emergency detachment apparatus (first emergency detachment apparatus) provided in the middle of each fluid handling pipe , The second emergency disengagement device) is activated, and first, the operation of the second emergency disengagement device of the second fluid handling tube attached to the first fluid handling tube is completed, and the second fluid handling tube is in a state where it can be divided, Thereafter, the operation of the first emergency detachment device for the first fluid handling pipe is completed, and the first fluid handling pipe is in a state where it can be separated. A fluid handling tube may for example be lifted by acting on itself or by this The structure is such that the land-side fluid handling pipes separated by the drive mechanism provided in the fluid handling pipe and the divided fluid-handling pipes on the sea side collide with each other and are damaged. .

  Further, since the avoidance operation of the fluid handling pipe is determined only by the state of the first fluid handling pipe, the first fluid handling pipe is divided earlier than the second fluid handling pipe attached to the first fluid handling pipe. If it becomes possible, the connected second fluid handling pipe (undivided) may be forcibly pulled up by the first fluid handling pipe and damaged due to the upward movement of the first fluid handling pipe Therefore, conventionally, for example, for each emergency release device of each fluid handling tube, a hydraulic cylinder mechanism for performing the separation operation of each emergency release device is provided, and these operation strokes are made different. And the separation operation of the second emergency disengagement device of the second fluid handling pipe is completed earlier than the separation operation of the first emergency disengagement device of the first fluid handling pipe due to the operation stroke difference of the hydraulic cylinder mechanism, First The second fluid handling tube was set to be ready divided before the fluid handling tube is capable disconnecting state.

  However, in the conventional fluid handling device, it is considered that the hydraulic cylinder mechanism that operates the separation operation of the emergency release device of the second fluid handling pipe may cause malfunction due to the inclusion of foreign matter or the like. The second emergency release device of the fluid handling pipe is not separable and the second fluid handling pipe is not separated (connected state), and it is forcibly pulled up and damaged by the first fluid handling pipe that moves up and down. Could cause trouble.

  The present invention has been made in view of such problems of the present situation, and the separation operation of the second emergency release device of the second fluid handling pipe is ensured together with the separation operation of the first emergency release device of the first fluid handling pipe. In addition, the separation operation of the second emergency release device is surely completed prior to the separation operation of the first emergency release device of the first fluid handling pipe, and the first fluid handling pipe is in a state where it can be separated. Before, when the second fluid handling tube is surely separable and the first fluid handling tube becomes separable and starts to move up, the first fluid handling tube and the first fluid handling tube An object of the present invention is to provide a fluid handling apparatus excellent in practicality in which the second fluid handling pipe attached to the pipe rises together, and emergency detachment is performed smoothly.

Since the lock mechanism 12 of the member 11 is also released, the first emergency release device 8 of the first fluid handling pipe 1 is separated to perform the second emergency release device 13 of the second fluid handling pipe 2. The separation operation is surely performed.

  In addition, the separation operation of the second emergency release device 13 of the present invention, that is, the release of the lock mechanism 12 of the second clamp member 11 that holds the second emergency release device 13 connected is the operation of the separation operation mechanism 6, specifically Since the operation of the separation operation moving part 14 that is moved by the operation of the separation operation mechanism 6 is transmitted to the lock mechanism 12 of the second clamp member 11 using a mechanical drive transmission means called the wire member 15, The operation of the separation operation mechanism 6 (separation operation moving portion 14) can be transmitted to the lock mechanism 12 of the second clamp member 11 easily and reliably with an extremely simple configuration. Since the length of the lock mechanism 12 of the second clamp member 11 for connecting and holding the second emergency release device 13 is set to be completed during the movement of the separation operation moving unit 14, the separation operation mechanism 6 is activated. The first emergency detachment of the first fluid handling pipe 1 8 is started, and the first emergency detachment device 8 becomes separable and the first fluid handling tube 1 becomes separable. The lock mechanism 12 of the second clamp member 11 of the device 13 is released, the second emergency release device 13 becomes separable, and the second fluid handling tube 2 becomes separable. In order to avoid breakage due to collision between the fluid handling pipes divided to the other side of the cargo handling, when the first fluid handling pipe 1 starts to move upward, the second fluid handling pipe 2 is also attached to the first fluid handling pipe 1. As a result, the second fluid handling pipe 2 is not divided as in the prior art, and there is no risk of causing damage to the first fluid handling pipe 1 or the second fluid handling pipe 2, and smooth emergency detachment is possible. It is an epoch-making fluid handling device with excellent practicality.

By configuring and coupling the couplers 10 to each other, a part of the on-off valve 9 protruding from both couplers 10 is pressed against each other against the extension bias of the biasing body 28, and each is pressed. Thus, the respective urging bodies 28 are retracted and the on-off valve 9 is opened.

  That is, the second emergency release device 13 of this embodiment opens the valve by retracting the urging body 28 against the extension urging force by pressing the on-off valves 9 in a state where the couplers 10 are connected to each other. When the coupler 10 is released by the emergency detachment operation and can be separated, the force of pressing the on-off valves 9 is lost, and the opening and closing of the urging body 28 instantaneously opens and closes. The valve 9 is configured to be closed and automatically switched to the closed state.

  Further, the release operation of the lock mechanism 12 of the second clamp member 11 that holds the coupling state of the couplers 10 of the second emergency release device 13 is performed by the separation operation mechanism 6 of the first fluid handling tube 1. It is configured.

  More specifically, the separating operation mechanism 6 includes a slide moving unit 19 serving as a separating operation moving unit 14 provided in the separating operation mechanism 6 and an operation transmitting wire member 15 connected between the lock mechanism 12. The operation of releasing the lock mechanism 12 is performed by transmitting the above operation.

  More specifically, as shown in FIG. 1, a tubular wire routing guide holding unit 20 (in this embodiment, a pipe is used for guiding and holding the routing of the wire member 15 between the slide moving unit 19 and the lock mechanism 12). The wire member 15 is inserted into the wire guide / holding portion 20 so that it is not caught between the fluid handling tube and other operation mechanisms, and the like between the slide moving portion 19 and the lock mechanism 12. When the wire member 15 is stretched and connected in a stretched state, the cylinder mechanism 16 is operated and the cylinder rod portion 17 (upper cylinder rod portion 17A) moves upward, the slide moving portion 19 is moved along with the movement of the cylinder rod portion 17. The wire member 15 is pulled by sliding upward along the slide guide portion 18 to pull the wire member 15. The pulling operation of the wire member 15 causes the lock mechanism 12 to be released. It has a configuration that is.

  Further, the wire member 15 of the present embodiment has a wire length set to a length that completes the release of the lock mechanism 12 during the stroke of the cylinder rod portion 17, that is, during the movement of the slide moving portion 19, in other words, The connecting positions of the wire member 15 to the slide moving part 19 and the lock mechanism 12 are connected to positions where the release of the lock mechanism 12 is completed during the movement of the slide moving part 19.

  More specifically, the cylinder rod portion 17 necessary for the valve closing operation for switching the opening / closing valve 3 of the first emergency release device 8 to the closed state is used for the locking mechanism 12 of the second clamp member 11 that is released by the wire member 15.

  In addition, the separation operation of the second emergency release device 13 of the present embodiment, that is, the release of the lock mechanism 12 of the second clamp member 11 that holds the second emergency release device 13 connected, Specifically, the operation of the slide moving unit 19 as the separating operation moving unit 14 that moves by the operation of the cylinder rod unit 17 of the cylinder mechanism 16 is used to lock the second clamp member 11 using a mechanical drive transmission means called a wire member 15. Since it is transmitted to the mechanism 12, the operation of the separation mechanism 6 (cylinder mechanism 16) can be transmitted to the lock mechanism 12 of the second clamp member 11 easily and reliably with an extremely simple configuration. The wire member 15 of the cylinder mechanism 16 completes the release of the lock mechanism 12 of the second clamp member 11 that holds the second emergency release device 13 during the stroke of the cylinder rod portion 17 of the cylinder mechanism 16, that is, during the movement of the slide moving portion 19. Length to do Since it is set, the cylinder mechanism 16 is activated, the separation operation of the first emergency release device 8 of the first fluid handling pipe 1 is started, and the first emergency release device 8 becomes separable and the first fluid handling pipe 1 The state where the lock mechanism 12 of the second clamp member 11 of the second emergency disengagement device 13 of the second fluid handling tube 2 is surely released and the second emergency disengagement device 13 is separable before the state becomes separable Thus, the second fluid handling pipe 2 becomes separable, and therefore the first fluid handling pipe 1 (the first fluid handling pipe 1) When one outboard arm 21) starts to move up, the second fluid handling pipe 2 (second outboard arm 25) also moves up together with the first fluid handling pipe 1 (first outboard arm 21). As a result, the conventional second fluid handling pipe 2 is not divided and the first flow No problem arises fear of causing damage to the cargo handling tube 1 and the second fluid handling tube 2, smooth emergency disengagement is innovative fluid handling device having excellent practicality performed.
