[0001] The present application relates to the technical field of marine offloading equipment, in particular to a rotary disc type soft pipe ship offloading system. BACKGROUND

[0002] When the sea shipping vessel stores liquid material in the tank and needs offloading operation, the offloading arm of the wharf can be adjusted to the side of the offloading end pipe of the sea shipping vessel until the offloading pipeline is connected with the offloading end pipe of the sea shipping vessel, so as to realize the effective input and output of the liquid material.

The loading and unloading arm mechanism 100 is used to provide suspension support for the external delivery mechanism 200. The external delivery mechanism 200 is used to cooperate with a marine vessel to transport liquid material. The coil pipe mechanism 300 is used to provide normal temperature regulation before the external delivery mechanism 200 transports liquid material. The hose winding and unwinding mechanism 400 is used to enhance the flexibility of the pipeline in the external delivery mechanism 200.

[0045] The loading and unloading arm mechanism 100 comprises a lifting rod 110 arranged on an external lifting mechanism, an end plate 130 movably mounted at the top end of the lifting rod 110, an auxiliary rotating shaft sleeve 120 mounted inside the end plate 130, a transmission pipe 150 movably mounted at one end of the auxiliary rotating shaft sleeve 120, and a top protection pipe 210 movably mounted at the other end of the auxiliary rotating shaft sleeve 120.

[0046] A transversely arranged clamping rod 140 is fixedly mounted on the outside of the lifting rod 110. A support frame 1401 is movably mounted in the clamping rod 140, and the transmission pipe 150 is inserted into the support frame 1401.

[0047] The external delivery mechanism 200 comprises a top protection pipe 210 and a bottom protection pipe 220. A plurality of annular sheaths 230 are uniformly arranged in the inner cavities of the top protection pipe 210 and the bottom protection pipe 220. A hose 240 is inserted into the plurality of annular sheaths 230.

[0048] The inner walls of the top protection pipe 210 and the bottom protection pipe 220 are coated with a heat insulation coating, and a refrigeration gap is reserved between the top protection pipe 210, the bottom protection pipe 220 and the hose 240.

[0049] A through hole is formed in the inside of the annular sheath 230. The ports at the top end and the bottom end of the annular sheath 230 are in a circular arc structure, and a plurality of air exchange grooves are uniformly arranged in the annular sheath 230.

[0050] The coil mechanism 300 comprises two protective cover plates 310 fixedly installed at the bottom end of the top protection pipe 210, a sealing back plate 320 fixedly installed on the two protective cover plates 310, an elongated insertion pipe 330 movably installed in the two protective cover plates 310, and the sealing back plate 320 adapted to be clamped in the slot on the inner side of the elongated insertion pipe 330, two clamping plates 350 fixedly installed at the bottom of the two protective cover plates 310, a shaft 3501 installed in the two clamping plates 350, a winding roller 3502 fixedly installed on the outer part of the shaft 3501, one end of a torsion spring 3504 fixedly installed on the inner wall of the winding roller 3502, the other end of the torsion spring 3504 fixedly installed on one of the clamping plates 350, an outer shell 3505 arranged on the outer part of the winding roller 3502, and a sealing strip 3503 wound on the outer part of the winding roller 3502, and the outer end of the sealing strip 3503 and the bottom end of the elongated insertion pipe 330 clamped and fixedly installed at the top end of the bottom protection pipe 220.

[0051] The top part of the two protective cover plates 310 is fixedly installed with a low-temperature gas flow transmission pipe 3101.

[0052] After the external lifting mechanism, i.e. the lifting rod 110 is pushed upward to the longest state by the external hydraulic module, the external lifting mechanism controls the lifting rod 110 to be tilted toward the sea shipping vessel, the end plate 130 movably installed at the top end of the lifting rod 110 adjusts the outer discharge mechanism 200 to approach the sea shipping vessel outer discharge pipeline, and after the bottom end joint of the bottom protection pipe 220 is connected with the sea shipping vessel outer discharge pipeline,

[0053] The low-temperature gas flow is continuously injected into the inner cavity of the two protective cover plates 310 by the low-temperature gas flow transmission pipe 3101, and under the continuous blowing effect of the normal temperature low-temperature gas flow, the soft pipe 240 in the constrained and straightened state can be subjected to normal temperature treatment before pre-transmission of the liquid material, and the normal temperature treated soft pipe 240 is centrally pressed by the plurality of annular sheaths 230, and after the liquid material in the storage tank is extracted outward by the normal temperature treated soft pipe 240, the soft pipe 240 under pressure expands and is restrained by the plurality of annular sheaths 230, thereby avoiding the problem of wear and tear of the outer wall of the expanded soft pipe 240 and the inner walls of the protective cover plates 310, the top protection pipe 210 and the bottom protection pipe 220.

[0054] The continuously normal temperature regulated soft pipe 240 can ensure the safety during the outer discharge of the liquid material.

[0055] According to the flexible requirement of the soft pipe 240, the length of the bottom protection pipe 220 is regulated by the sealing strip 3503 and the elongated insertion pipe 330, and the elongated insertion pipe 330 slot is blocked by the sealing back plate 320, so that the length of the bottom protection pipe 220 after adjustment will not have the phenomenon of gas overflow. Embodiment 2

[0056] In combination Figures 6 to 9As shown, on the basis of Embodiment 1, the coil mechanism 300 further comprises two upright columns 3701, a guide rod 3702 is fixedly installed inside the upright column 3701, a spring 3704 is arranged outside the guide rod 3702, one end of the spring 3704 is fixedly installed on the upright column 3701, and a stabilizing gasket 3703 is movably installed outside the guide rod 3702 and is adapted to be clamped on the inner side of the adjacent two slide bars 370;

[0057] The other end of the spring 3704 is fixedly installed on the stabilizing gasket 3703;

[0058] The guide rod 3702 has a T-shaped structure as a whole, and two guide rods 3702 are equidistantly arranged at the top and bottom of the two track frames 360, for enhancing the stability of the horizontal movement of the two drive wheels 3804;

[0059] Preferably, the number of slide bars 370 is four, and the adjacent two slide bars 370 are used to provide effective support for the lateral sliding of the stabilizing gasket 3703, and the arc-shaped end faces of the two stabilizing gaskets 3703 are used to protect the outer wall of the side-bent part of the hose 240, and the two springs 3704 provide elastic support for the two stabilizing gaskets 3703, so that the two springs 3704 can exert a compression force on the side-bent part of the hose 240 after the hose 240 finishes the external delivery work, thereby accelerating the rapid emptying of the residual material in the inner cavity of the hose 240.

[0060] The inner wall of the protective cover plate 310 movably installs two guide wheels 340 which are symmetrically distributed, the two slide bars 370 are fixedly installed on the inner wall of the protective cover plate 310, the track frames 360 are fixedly installed on the middle part of the inner side of the protective cover plate 310, the auxiliary shaft 3803 is movably installed on the inner side of the two track frames 360, the two drive wheels 3804 are fixedly installed on the outer side of the auxiliary shaft 3803, and the auxiliary gear 3805 is fixedly installed on the auxiliary shaft 3803;

[0061] The middle part of the auxiliary shaft 3803 movably installs a drawer plate 380, two groups of clamps 3801 are fixedly installed on the two ends of the drawer plate 380, and a linkage shaft 3802 is movably installed in the two groups of clamps 3801;

[0062] The linkage shaft 3802 is composed of a beam and two deflection gears, and one of the deflection gears is adapted to be engaged with the auxiliary gear 3805.

[0063] Preferably, the drawer plate 380 is located in the middle part of the inner side of the two track frames 360, and the drawer plate 380 is used to provide stabilizing support for the auxiliary shaft 3803 and the two drive wheels 3804, and the lateral movement of the drawer plate 380 is controlled to control the auxiliary driving of the two drive wheels 3804 on the side-bent part of the hose 240;

[0064] When the linkage shaft 3802 is driven and rotates the power-assisted gear 3805 and the power-assisted shaft rod 3803, the two drive wheels 3804 can uniformly assist the hose 240, and cooperate with the continuous expansion of the drawer plate 380 outward, so that the assisted hose 240 can be flexibly adjusted during the external delivery of the liquid material, thereby avoiding the phenomenon of over-expansion of the hose 240 when the liquid material enters the inside of the hose 240. Embodiment 3

[0065] In combination Figure 3 and 4 As shown in FIG. 4, in the above embodiment, the hose winding and unwinding mechanism 400 includes a slide rail 410 fixedly installed outside one of the protective cover plates 310, a base 420 movably installed in the slide rail 410, a motor 4201 fixedly installed inside the base 420, a drive gear 4202 fixedly installed on the motor 4201 and adapted to engage with the other deflection gear, two legs 4203 fixedly installed outside the base 420, and a support plate 4204 movably installed in the two legs 4203.

[0066] An end of the drawer plate 380 penetrating outside the two protective cover plates 310 is fixedly installed on the base 420.

[0067] The hose winding and unwinding mechanism 400 further includes two groups of supports 430 fixedly installed outside one of the protective cover plates 310, and the two groups of supports 430 are adapted to align with the slide rail 410. A hydraulic component 440 is fixedly installed inside the two groups of supports 430, and an outer end of a hydraulic sub-rod in the hydraulic component 440 is installed in the support plate 4204.

[0068] Preferably, the back of the slide rail 410 is welded to the middle of the outside of the protective cover plate 310, and a slide channel is formed in the inside of the slide rail 410. A slide block adapted to be clamped in the slide channel is fixedly installed on the side of the base 420 facing the slide rail 410. A machine box is fixedly installed at the outer end of the base 420, and the motor 4201 is fixed in the inside of the machine box and electrically connected with an external control module.

[0069] When the hydraulic component 440 operates and pushes the support plate 4204, the legs 4203 and the base 420 drive the drawer plate 380 to expand laterally. At this time, the hose 240 for external delivery of the liquid material can be flexibly enhanced in the normal temperature pretreatment state. By avoiding direct contact between the hose 240 and the metal pipe wall, and continuously inputting low-temperature gas flow into the metal pipe cavity, the flexibility of the hose 240 is enhanced, the friction resistance of the hose 240 is prevented from becoming large due to excessive heating in the metal pipe cavity, and the problem of accelerated aging after the hose 240 is inflated due to the delivery of the liquid material is avoided.

[0070] The working principle and use process of the application: when the marine ship approaches the top position and needs to carry out the external delivery operation of the liquid material, the external lifting mechanism is used to push the lifting rod 110 to rise, and the external lifting mechanism drives the lifting rod 110 to tilt towards the marine ship external delivery pipe until the joint at the lowest end of the bottom protection pipe 220 is connected with the marine ship external delivery pipe;

[0071] Then the external pipeline is connected with the low-temperature gas flow transmission pipe 3101, and the low-temperature gas flow is input to the inner cavities of the two protective cover plates 310. After the continuous input of the low-temperature gas flow, the two protective cover plates 310, the top protection pipe 210 and the bottom protection pipe 220 connected rear cavity can continuously cool the soft pipe 240 of the built-in structure, and the pretreated soft pipe 240 can safely deliver the liquid material in the marine ship, avoiding the problem of pipe body explosion caused by the temperature difference between the soft pipe 240 and the liquid material in the marine ship;

[0072] Since the soft pipe 240 passes through the structure at the lowest end of the bottom protection pipe 220 after connecting with the marine ship external delivery end pipe, it needs to provide an external delivery channel for the liquid material in the storage tank. When the liquid material enters the inside of the soft pipe 240 and is pulled out upward, the soft pipe 240 built in the inner cavities of the top protection pipe 210, the bottom protection pipe 220 and the two protective cover plates 310 will be wrinkled under pressure, and in severe cases, the outer wall of the soft pipe 240 will be abraded with the inner wall of the top protection pipe 210, the bottom protection pipe 220 and the two protective cover plates 310. Therefore, before the liquid material is delivered, the cloud starts the motor 4201, and the motor 4201 cooperates with the drive gear 4202 to drive the outer end of the linkage shaft 3802. Another deflection gear at the inner end of the linkage shaft 3802 assists the drive gear 3805, the auxiliary shaft 3803 and the drive wheel 3804. The side bending part of the soft pipe 240 on the inner side of the drive wheel 3804 can be assisted to stretch. At the same time, the hydraulic part 440 is operated again until the hydraulic sub-shaft of the hydraulic part 440 pushes the supporting plate 4204 and the supporting leg 4203, and the base 420 pushes the motor 4201 and the whole drawer plate 380 to move outward, and finally the drive wheel 3804 continuously stretches the side bending part of the soft pipe 240 while providing effective pressure relief for the soft pipe 240 which is expanded under pressure, thereby avoiding the problem of abrasion between the soft pipe 240 and the inner wall of the top protection pipe 210, the bottom protection pipe 220 and the two protective cover plates 310 during the delivery of the liquid material. The flexibility of the soft pipe 240 is enhanced, and the damage of the soft pipe 240 to the delivered material is reduced;

[0073] In order to avoid elongation and increase the normal temperature state of the flexible hose 240 during the delivery of liquid material, the elongated insertion tube 330 is lowered synchronously with the bottom protection tube 220, and the inner groove of the elongated insertion tube 330 is stably lowered along the sealing back plate 320. At the same time, the sealing strip 3503 connected to the top end of the bottom protection tube 220 is also adapted to the groove of the elongated insertion tube 330 for sealing. At this time, the elongated hose 240 can always be maintained in an effective and sealed normal temperature environment, and the hose 240 is not affected by the ambient temperature during the transmission of liquid material and expansion, thereby ensuring that the hose 240 does not have excessive wear problems with the steel pipe wall during the inflation.

[0074] Although embodiments of the present application have been shown and described, it would be appreciated by those skilled in the art that changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the application, and the scope of the present application is defined by the claims and their equivalents.
