Description

Technical Field

[0001] The invention relates to the technical field of port ship pressure vessel transfer hangers, in particular to a pressure-covering positioning port ship pressure vessel transfer hanger. Background Art

[0002] Ships are used in ports to transport oil and natural gas. Pressure vessels are used to store oil and natural gas during transportation to avoid explosions and other dangerous situations of these flammable and explosive oil products. Since the pressure vessels are large in size, they need to be hoisted and transported by transfer hangers during processing and use. The patent name disclosed in the prior art with the announcement number "CN114655839A" is "A method for lifting and transporting a nuclear material shielding container". It discloses that the left lifting arm and the right lifting arm are fixed to the connecting hole of the wedge block by a fixing piece, and the lifting ring drives the screw main shaft and the spring seat to move up and down with the wedge block under the action of the large spring. The left lifting arm and the right lifting arm have a matching notch, and the bottom of the notch has a drum-shaped sleeve, which is perpendicular to the notch and is fixed to the eccentric bottom of the notch through a connecting shaft. Position, the slots of the left lifting arm and the right lifting arm are offset to the slots by one slot wall thickness and sleeved on the screw main shaft, so that the most bulging parts of the two drum-shaped sleeves and the diameter line of the screw main shaft are on the same line. When the left lifting arm and the right lifting arm are lifted, they rotate synchronously around the centers of the two connecting shafts in two directions at the same angle to achieve the opening and closing action of the left lifting arm and the right lifting arm. The size of the distance ensures that the left lifting arm and the right lifting arm can be disengaged from the container when they are opened to the maximum, and are smaller than the distance between the two bosses of the container when they are opened to the minimum, so as to ensure that the container is clamped; The patent name disclosed in the prior art with the announcement number "CN115947216B" is "A transfer sling for hazardous waste containers". It discloses that when lifting and transferring a barrel containing hazardous chemicals, stability is more required. The device is moved to the top of the barrel through a lifting device. When the device descends, four connecting rods are inserted from the surrounding space of a barrel until the magnet contacts the top of the barrel. At this time, the magnet is restricted by the top of the barrel, and the device continues to move downward until the telescopic unit is completely shortened. At this time, the screw rod remains stationary, and the upper connecting plate and the lower connecting plate continue to move downward under the action of gravity, and the gear moves downward accordingly. At this time, the lower connecting plate moves downward relative to the screw rod, and the inner cavity ball of the gear moves along the spiral groove on the surface of the screw rod to realize the rotation of the gear. When the gear rotates, it drives the four racks to move synchronously, and the rack pulls the sliding plate and the connecting piece to move along the limiting groove. The sliding plate pulls the connecting rod to move, and the connecting rod drives the hook at the bottom to move until the outer side of the hook is completely in contact with the smooth outer wall of the barrel.

[0003] When the transfer hanger for port ship pressure vessels in the above-mentioned prior art is in use, the hook at the bottom is moved only by the connecting rod, so that the outer side of the hook is completely in contact with the smooth outer wall of the barrel body, so as to clamp the barrel body for transfer and lifting. This operation will result in a smaller clamping degree for the port ship pressure vessel. During the process of transfer and lifting, the port ship pressure vessel may fall off or other dangerous situations may occur, thereby affecting the subsequent transfer and lifting operations.

[0004] Therefore, we propose a pressure-covering positioning transfer hanger for port ship pressure vessels to solve the above-mentioned problems. Summary of the invention

[0022] The connection mechanism includes a lifting head 91 screwedly installed above the water pipe support seat 8, and a water pipe support frame 9 is installed above the lifting head 91; a pad is installed inside the upper middle part of the container bottom support 3, above the water pipe support frame 9, and on the inner side of the pressure control block 152, and the pad is made of POM material. The bottom surface of the pressure vessel body 16 is arranged in contact with the upper surface of the container bottom support 3, and the outer side surface of the pressure vessel body 16 is installed with water pipe bodies 161 at equal intervals, and the water pipe support frame 9 is arranged below the water pipe body 161. The interior of the opening and closing arm 11 is penetrated by screws. The groove is connected with an adjusting threaded rod 12, one end of which is rotatably connected to the outer side of the pressure-covering adjusting block 15; the upper and lower sides of the opening and closing arm 11 are symmetrically rotatably installed with connecting plates 111, one end of which is connected to a vertical rod 112; a through groove 151 is opened inside the pressure-covering adjusting block 15, and the vertical rod 112 is penetrated through the through groove 151; the fixed arc frame 10, the opening and closing arm 11, the pressure-covering adjusting block 15, the through groove 151 and the pressure-covering control block 152 are all arranged in an arc-shaped structure, and the four groups of fixed arc frames 10 and the opening and closing arms 11 constitute a complete circular ring structure.

[0023] First, manually pull the manual locking pin 113 in the locking mechanism upward in sequence, so that the manual locking pin 113 is separated from the locking hole 102 in the corresponding fixed arc frame 10 and the through hole in one end of the opening and closing arm 11. At this time, the opening and closing arm 11 can be manually rotated so that the other end of the opening and closing arm 11 can be well rotated and unfolded with the corresponding fixed arc frame 10 through the movable shaft. At this time, the pressure vessel body 16 is placed in the connecting pipe welded part with a cage structure composed of the support column 6, the cage-type fixed ring frame 7 and the fixed arc frame 10. At this time, the bottom of the pressure vessel body 16 will contact the pad embedded and installed in the middle above the bottom support 3 of the container. At this time, the bottom support of the container 3 will be placed at the bottom of the pressure vessel body 16, and the cage-type connecting pipe welding parts will limit and block the surroundings of the pressure vessel body 16. At this time, the water receiving pipe body 161 is placed on the water receiving pipe support frame 9, and the water receiving pipe body 161 is placed by the water receiving pipe support frame 9 and the pad on the upper surface. Then, as shown above, the opening and closing arm 11 is rotated in the opposite direction, so that one end of the opening and closing arm 11 is rotated into the fixed arc frame 10 at the corresponding position, and then the manual locking pin 113 is inserted into the locking hole 102, so as to lock the rotated opening and closing arm 11, so that the four groups of opening and closing arms 11 and the fixed arc frame 10 form a complete ring shape.

[0024] Then, the four adjusting threaded rods 12 are manually rotated in sequence. Since the adjusting threaded rods 12 are threadedly connected to the opening and closing arms 11, the adjusting threaded rods 12 rotate while driving the pressure-covering adjusting block 15 and the pressure-covering control block 152 to move inward. At this time, the vertical rod 112 connected to one end of the connecting plate 111 slides in the through groove 151 with an arc-shaped structure, thereby ensuring that the pressure-covering adjusting block 15 and the pressure-covering control block 152 move inward stably. At this time, the pressure-covering control block 152 with an inclined inner side surface is well aligned with the outer surface above the pressure vessel body 16 The tapered collar on the side is pressed and positioned, so that the upper outer side surface of the pressure vessel body 16 can be squeezed and fixed stably, ensuring that the pressure vessel body 16 is stably placed in the entire transfer hanger. Then the hand winch 2 is connected to the main lifting shackle 13. The maximum load-bearing capacity of a single main lifting shackle 13 is 1200KN. Then the cross sling mechanism 1 is connected to an external crane. At this time, the entire transfer hanger can stably transfer and lift the pressure vessel body 16, thereby preventing the pressure vessel body 16 from tipping over and falling.

[0025] Embodiment 2: The pressure-covering positioning port ship pressure vessel transfer hanger in this embodiment is based on the embodiment 1, by adding a transfer chassis 14, so that the entire transfer hanger can be used as an integral transport bracket to meet different usage requirements. For specific structures, refer to the attached Figure 5-Figure 8As shown, four groups of positioning pins 301 for positioning and guiding are correspondingly installed on the bottom surface of the container bottom support 3, and the lower ends of the positioning pins 301 are inserted into the corresponding positioning holes on the upper surface of the transfer chassis 14. The upper surface of the transfer chassis 14 is grooved with equal intervals and equipped with clamping cylinders 141. The output end of the clamping cylinder 141 is connected to a clamping block 142 in a "7"-shaped structure, and the clamping block 142 is connected to the outer side below the container bottom support 3; side pull shackles 143 are symmetrically installed at the four corners of the surface of the transfer chassis 14, and the side pull shackles 143 are connected to the hand winch 2. First, the container bottom support 3 is lifted upward, and then the transfer chassis 14 is placed directly below the container bottom support 3. At this time, the bottom support 3 of the container is moved downward, and the four positioning pins 301 on the bottom surface of the bottom support 3 of the container are inserted into the corresponding positioning holes on the transfer chassis 14. Then the hand winch 2 is connected and tightened with the side pull buckle 143, and then the clamping cylinder 141 is started. The output end of the clamping cylinder 141 drives the clamping block 142 in a "7" shape to move, so that the clamping block 142 clamps the outer side of the bottom support 3 of the container, and then as shown in Example 1, similarly, the pressure vessel body 16 is placed in the transfer hanger, and then the pressure vessel body 16 can be transferred to the pre-assembly workshop through the transfer chassis 14, so it can meet different usage requirements.

[0026] Embodiment 3: The pressure-covering positioning port ship pressure vessel transfer hanger in this embodiment, on the basis of embodiment 1, can completely separate the bottom surface of the pressure vessel body 16 from the bottom support 3 of the container through the jacking head 91, so as to facilitate use during insulation operation, which can meet different usage requirements. The connection mechanism includes a support frame cylinder 92 installed in the water pipe support seat 8, and the output end of the support frame cylinder 92 passes through the upper surface of the water pipe support seat 8 and is connected to the jacking head 91. A water pipe support frame 9 is installed above the jacking head 91. When the pressure vessel body 16 is placed on the bottom support 3 of the container, the water pipe body 1 on the outside of the pressure vessel body 16 is 61 is placed above the water receiving pipe support frame 9 at the corresponding position, and then the pressure vessel body 16 can be transferred and hoisted as shown in Example 1. When the pressure vessel body 16 needs to be insulated, the lifting head 91 and the water receiving pipe support frame 9 are synchronously moved upward by the four groups of support frame cylinders 92, so that the water receiving pipe support frame 9 pushes the water receiving pipe body 161 on the outside of the pressure vessel body 16 upward, thereby moving the pressure vessel body 16 upward, so that the bottom surface of the pressure vessel body 16 is completely separated from the bottom support 3 of the container, and then the pressure vessel body 16 can be insulated, so it can meet different usage requirements.

[0027] Embodiment 4: The pressure-covering type positioning port ship pressure vessel transfer hanger in this embodiment provides another structure of locking mechanism on the basis of embodiment 1, through which the rotating opening and closing arm 11 can be automatically locked, which is more convenient to operate, saves time and effort, and the specific structure is shown in the attached figure. Figure 13-14 As shown, the locking mechanism includes an automatic locking rod 114 installed in a groove at one end of the opening and closing arm 11, the lower end of the automatic locking rod 114 is connected to the inside of the opening and closing arm 11 through a connecting spring 115, the upper end of the automatic locking rod 114 is arranged in an inclined shape, the upper end of the automatic locking rod 114 is inserted into the locking hole 102 opened inside the upper end of the fixed arc frame 10, and the upper outer side of the movable shaft is nested and connected with a vortex spring 101. When the opening and closing arm 11 needs to be rotated outward and expanded, the automatic locking rod 114 is manually pressed downward at this time. At this time, the automatic locking rod 114 moves downward to squeeze and store force on the connecting spring 115, and then the upper part of the automatic locking rod 114 is separated from the locking hole 102. At this time, the movable shaft and the opening and closing arm 11 can be automatically driven to rotate by the stored force of the vortex spring 101, thereby making the opening and closing arm 11 It can be easily unfolded by rotating outward. When the opening and closing arm 11 needs to be rotated inward, the opening and closing arm 11 can be rotated manually. At this time, one end of the opening and closing arm 11 is rotated close to the corresponding fixed arc frame 10. At this time, the outer side surface of the fixed arc frame 10 will automatically apply a downward pressure to the automatic locking rod 114 which is inclined above. At this time, the automatic locking rod 114 squeezes and accumulates force on the connecting spring 115. Then, when one end of the opening and closing arm 11 is rotated into the corresponding fixed arc frame 10, the force accumulated by the connecting spring 115 automatically drives the automatic locking rod 114 to move upward and reset, so that the upper end of the automatic locking rod 114 is inserted into the locking hole 102. At this time, the vortex spring 101 accumulates force, thereby automatically locking. The operation is convenient, time-saving and labor-saving. You only need to manually push the opening and closing arm 11 to rotate.
