Description

Technical Field

[0001] The present invention relates to the technical field of loading arms, and particularly relates to an automated unloading system. Background Art

[0002] In fields such as petrochemical industry and warehousing logistics, the unloading operation of liquid media (such as refined oil and chemical raw materials) from oil tank trucks through a loading arm system is a core operation process. The traditional loading arm unloading system usually consists of multiple rotatable pipes, quick connectors, and manual locking mechanisms.

[0003] For example, a leak detection system for a loading arm for unloading liquid chlorine with the application number 202411804253.4 includes a fixed pipe and a movable pipe, and a heat insulation structure is provided on the fixed pipe and the movable pipe; the heat insulation structure is used for heat preservation inside the fixed pipe and the movable pipe; a temperature detection member for obtaining the temperature of the heat insulation structure is provided at the heat insulation structure; a socket matching the filling port of the tank truck is formed on the fixed pipe; the movable pipe is inserted into the socket so that the fixed pipe and the movable pipe form a closed loop; a gas thermal imaging member is provided on the fixed pipe, and the gas thermal imaging member forms a gas detection area that covers the movable pipe.

[0004] The above technical solutions have some problems in the process of use compared with the traditional unloading system. There are deficiencies in the reliability of connection and fixation in actual application, a lack of connection state detection mechanism, which is likely to cause leakage at the connection position, the sealing performance of multiple pipes is weak, and it is easy to cause sealing failure due to wear during long-term use. The connection between the loading arm and the tank truck pipeline is mostly manual operation, wasting human resources, and the loading arm itself is relatively heavy, making it inconvenient for personnel to operate.

[0017] Technical effects and advantages of the present invention: 1. The present invention effectively achieves the purpose of improving the stability of pipeline connection by providing a connecting component and a fixed pipe. In the process of inserting the end of the fixed pipe into the oil unloading pipe, the end of the fixed pipe contacts the end of the hook plate to make it flip and squeeze the spring. When the fixed pipe is inserted into the appropriate position, the end of the fixed pipe pushes the middle of the hook plate to flip and reset it. At the same time, the spring further pushes the hook plate to insert the end of the hook plate into the groove. At this time, the fixed pipe and the oil unloading pipe are relatively fixed, and the pressing handle is turned inward by the pressing ring, and the pressing handle is inserted into the pressing groove, so that the fixed pipe and the oil unloading pipe are further fixed, and the stability is improved. Through a variety of connection methods, the oil unloading pipe is relatively stable and sealed relative to the fixed pipe, avoiding safety accidents caused by oil leakage during oil unloading.

[0018] 2. By providing a pressing handle, a pressing ring, an air storage bag, and a monitoring module, the present invention adds a function for detecting the connection state. During use, if the pressing handle does not correspond to the pressing groove, the pressing handle will not squeeze the air storage bag, the monitoring module will not be triggered, the surface fixing pipe and the oil discharge pipe are not effectively connected, and the tanker cannot discharge oil, achieving the purpose of monitoring whether the pipeline is tightly connected and improving the safety of oil discharge. When the pressing handle can be inserted into the pressing groove, the end of the pressing handle will squeeze the air storage bag to trigger the monitoring module, indicating that the fixing pipe and the oil discharge pipe are connected, and the tanker can be controlled to discharge oil, helping the operator confirm whether the locking is in place and reducing the risk of misjudgment.

[0019] 3. By providing a sealing rotation assembly and a sealing component, the present invention optimizes the sealing effect between multiple pipelines. When the output end of the driving member contacts the friction disk, the linear driving part pushes the pressing rod to flip through the driving plate, and the pressing rod drives the extrusion rod to rotate synchronously through the pushing rod. At this time, the elastic piece deforms to squeeze the air storage part, improving the relative seal between the arc-shaped pipe and the extension pipe. The air storage part and the expansion part are connected through a pipeline, and at the same time, the expansion part is inflated to improve the relative sealing effect between the main oil pipe, the extension pipe, and the bent pipe.

[0020] 4. By providing a linear driving part, a rotation driving part, a driving wheel, and a driven wheel, the present invention effectively reduces the labor pressure of personnel. During use, by controlling the extension of the linear driving part, the extension pipe rotates relative to the arc-shaped pipe, and at the same time, by controlling the rotation of multiple rotation driving parts, the movable ring rotates relative to the fixed ring. Multiple sealing components work together to adjust the position of the oil discharge pipe, making the oil discharge pipe correspond to the fixed pipe. Subsequently, the end of the oil discharge pipe is sleeved on the end of the fixed pipe, reducing the distance of manually pulling the loading arm, reducing the working pressure, and at the same time avoiding the wear of the sealing components between the pipelines caused by the relative rotation of multiple pipelines and the uneven manual pulling force when manually pulling the loading arm.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides as Figures 1 to 10An automated truck unloading system as shown includes a support rod 1 which is fixed to the ground. The bottom of the support rod 1 is installed on the horizontal ground by bolts; a main oil pipe 2 which is rotatably connected to one side of the support rod 1. One end of the main oil pipe 2 is communicated with a storage tank. The main oil pipe 2 can rotate relative to the support rod 1. The main oil pipe 2 is T-shaped and has a hollow structure; an arc-shaped pipe 3 which is rotatably connected to the other end of the main oil pipe 2. The arc-shaped pipe 3 is bent in a 90-degree L shape; an extension pipe 4 which is rotatably connected to the other end of the arc-shaped pipe 3. The extension pipe 4, the arc-shaped pipe 3, and the main oil pipe 2 are communicated in sequence. The extension pipe 4 is bent in a Z shape; a sealing rotation assembly 5 which is rotatably connected between the arc-shaped pipe 3 and the extension pipe 4 and is used to detect the sealing performance of the pipeline connection position; a bent pipe 6 which is rotatably connected to the end of the extension pipe 4. The bent pipe 6 is bent at 90 degrees; an oil discharge pipe 7 which is rotatably connected to the end of the bent pipe 6. The other end thereof is provided with an engagement assembly 8. The oil discharge pipe 7, the bent pipe 6, and the extension pipe 4 are communicated in sequence. The engagement assembly 8 includes: a pressure handle 801 which is rotatably connected to the outside of the oil discharge pipe 7 and is evenly provided with a plurality of them; a pressure ring 802 which is sleeved on the outside of the oil discharge pipe 7 and contacts a plurality of pressure handles 801 and is used to push the pressure handle 801 to flip. When in use, the pressure ring 802 moves to squeeze the outside of the pressure handle 801 to make the pressure handle 801 flip and be fixed. After the pressure ring 802 is reset, it is necessary to manually reset the pressure handle 801; a fixed pipe 9 which is installed at the oil outlet position of the tanker. The end of the fixed pipe 9 is pre-installed at the oil outlet position of the tanker through a flange. The oil discharge pipe 7 can be communicated with the fixed pipe 9, and the relative position of the oil discharge pipe 7 and the fixed pipe 9 is locked through the engagement assembly 8.

[0034] It should be noted that a control valve is provided at the oil outlet of the tanker, which can independently control whether to unload oil, avoid oil leakage in the tanker, and control the tanker to unload oil at an appropriate time.

[0035] Specifically, the engagement assembly 8 further includes: a hook plate 803 which is rotatably connected to the outside of the oil discharge pipe 7 and is evenly provided with a plurality of them. The hook plate 803 and the pressure handle 801 are arranged alternately. One side of each hook plate 803 is fixedly connected with a reed 804. The other end of the reed 804 abuts against the oil discharge pipe 7; a groove 805 which is opened on the outside of the fixed pipe 9 and corresponds to the hook plate 803 one by one. The end of the hook plate 803 can be inserted into the groove 805 to limit the fixed pipe 9. During the use process, the oil discharge pipe 7 moves to a position corresponding to the fixed pipe 9 and moves towards the fixed pipe 9, so that the end of the fixed pipe 9 is inserted into the oil discharge pipe 7. At this time, the end of the fixed pipe 9 abuts against the end of the hook plate 803 to make it flip outward and squeeze the reed 804. When the fixed pipe 9 is inserted to an appropriate position, the end of the fixed pipe 9 pushes the middle part of the hook plate 803 to make it flip and reset, and inserts the end of the hook plate 803 into the groove 805. At this time, the fixed pipe 9 and the oil discharge pipe 7 are relatively fixed.

[0036] More specifically, it also includes a grooved slot 806, which corresponds to the pressing handle 801 one by one and is opened on the outer side of the fixed pipe 9. During use, the pressing handle 801 is pushed by the pressing ring 802 and turns inwards, so that the pressing handle 801 is inserted into the grooved slot 806 to further fix the fixed pipe 9 and the oil discharge pipe 7, improving the stability; a storage airbag 807, which is fixedly sleeved on the outer side of the oil discharge pipe 7, and the end of each pressing handle 801 can press the storage airbag 807; a monitoring module 810, which is fixedly connected to the middle of the oil discharge pipe 7 and is used to monitor the air pressure of the storage airbag 807. The monitoring module 810 is a pressure sensor or a micro-motion sensor, which is used to monitor the pressure in the storage airbag 807 or the deformation of the storage airbag 807. When the fixed rod and the oil discharge pipe 7 are fixedly connected through the pressing handle 801, the end of the pressing handle 801 squeezes the storage airbag 807 to trigger the monitoring module 810, indicating that the connection between the fixed pipe 9 and the oil discharge pipe 7 is completed, and the tanker can be controlled to discharge oil; if the pressing handle 801 and the grooved slot 806 do not correspond, the pressing handle 801 cannot be turned to the state of squeezing the storage airbag 807, and the monitoring module 810 will not be triggered, indicating that the fixed pipe 9 and the oil discharge pipe 7 are not connected, and the tanker cannot be made to discharge oil, improving the safety of oil discharge and achieving the purpose of monitoring whether the pipeline is tightly connected, and avoiding oil leakage caused by oil discharge when the pipeline is not tightly connected; a pull rod 808, which is fixedly connected to one side of the pressing ring 802 and is evenly provided with a plurality of them. The pull rod 808 is slidably matched with the oil discharge pipe 7; a pull wire 809, one end of which is fixedly connected to a plurality of pull rods 808, and the other end is connected to the sealing rotating assembly 5. The sealing rotating assembly 5 makes the pull rod 808 pull the pressing ring 802 to move through the pull wire 809, forcing the pressing handle 801 to rotate to lock the oil discharge pipe 7 and the fixed pipe 9.

[0037] It should be noted that the pull wire 809 is divided into an outer tube 8091 and an inner wire 8092. The inner wire 8092 is placed inside the outer tube 8091 and can slide relative to the outer tube 8091. One end of the outer tube 8091 is fixedly connected to the oil discharge pipe 7, and the other end is fixedly connected to the fixed ring 501; one end of the inner wire 8092 is fixedly connected to the pull rod 808, and the other end is fixedly connected to the extrusion rod 508.

[0038] It should be pointed out that after the oil discharge is completed, the pull wire 809 needs to be relaxed so that the pressing ring 802 can be reset. Subsequently, the pressing handle 801 and the hook plate 803 are manually reset to unlock the fixed pipe 9 and the oil discharge pipe 7, and they are manually separated to complete the oil discharge work.

[0039] Specifically, sealing components 10 are provided at the connection positions of the bent pipe 6 with the oil discharge pipe 7 and the extension pipe 4, and at the connection position of the arc-shaped pipe 3 with the main oil pipe 2. The sealing components 10 are used to improve the sealing performance of the pipeline connection positions.

[0040] More specifically, the sealed rotating assembly 5 includes: a fixed ring 501, which is fixedly connected to the end of the arc-shaped tube 3 through a flange; a movable ring 502, which is rotatably sleeved outside the fixed ring 501 and is fixedly connected to the end of the extension tube 4 through a flange. A bearing is sleeved between the fixed ring 501 and the movable ring 502 to facilitate the rotation of the movable ring 502 relative to the fixed ring 501; a gas storage part 503, which is sleeved inside the fixed ring 501, and the contact position between the arc-shaped tube 3 and the extension tube 4 is placed inside the gas storage part 503. When the gas storage part 503 is compressed and expanded, it can squeeze the connection position between the arc-shaped tube 3 and the extension tube 4 to improve the sealing performance; a support frame 504, which is fixedly connected to the outside of the fixed ring 501 and is provided with a locking device 505 in the middle for locking the relative positions of the movable ring 502 and the fixed ring 501; the locking device 505 includes a friction disc 5051, which is fixedly sleeved outside the movable ring 502 and has a rough frosted plane on one side; a driving member 5052, which is fixedly connected to the middle of the support frame 504 and the output end of which can contact the friction disc 5051. The driving member 5052 is a component such as a linear motor, an electromagnetic push rod or a hydraulic rod that can realize the linear movement of the output end. When in use, the driving member 5052 is electrically connected to a corresponding controller and a power supply, and its output end is fixedly connected with a friction plate that can contact the friction disc 5051, and the relative fixation of the movable ring 502 and the fixed ring 501 is achieved through their mutual friction.

[0041] Specifically, the sealed rotating assembly 5 further includes: a pressing rod 506, which is rotatably connected to the upper end of the support frame 504 and is rotatably connected with a push rod 507 in the middle. A cylindrical boss is fixedly connected to the upper end of the pressing rod 506; an extrusion rod 508, which is rotatably connected to the upper end of the support frame 504 and is rotatably connected with the push rod 507 in the middle. An elastic piece 509 is provided on the side of the extrusion rod 508 away from the push rod 507. When in use, the pressing rod 506 is flipped to make the extrusion rod 508 flip downward through the push rod 507. At this time, the elastic piece 509 is compressed and deformed; a notch is opened at the position of the fixed ring 501 corresponding to the elastic piece 509. The compression of the elastic piece 509 can squeeze the gas storage part 503, and when the elastic piece 509 is compressed and deformed, it can only bend toward the side close to the gas storage part 503 to compress the gas storage part 503; a linear driving part 510, which is rotatably connected to the outside of the extension tube 4 and the output end of which is fixedly connected with a driving plate 511. The end of the pressing rod 506 is slidably matched with the driving plate 511. The linear driving part 510 is a component such as a linear cylinder or a hydraulic rod that can extend linearly. During the use process, the linear driving part 510 is connected with a corresponding controller and a power supply.

[0042] It should be noted that when the friction plate at the output end of the driving member 5052 does not contact the friction disc 5051, one side of the friction plate contacts the position where the extrusion rod 508 rotates relative to the support frame 504, and generates a frictional force with the extrusion rod 508, so that the extrusion rod 508 is fixed relative to the support frame 504. At this time, the extrusion rod 508 cannot rotate.

[0043] During use, adjust the output end of the driving member 5052 so that it does not contact the friction plate. At this time, control the linear driving part 510 to extend, and the driving plate 511 pushes the pressing rod 506. However, since the output end of the driving member 5052 locks the extrusion rod 508, when the linear driving part 510 extends, the extension pipe 4 rotates relative to the arc-shaped pipe 3, adjusting the position of the oil discharge pipe 7 relative to the fixed pipe 9; when the output end of the driving member 5052 contacts the friction disc 5051, the movable ring 502 is fixed relative to the fixed ring 501, and the extrusion rod 508 is unlocked. At this time, the linear driving part 510 pushes the pressing rod 506 to flip through the driving plate 511, and the extrusion rod 508 rotates synchronously through the push rod 507. At this time, the elastic piece 509 deforms to squeeze the air storage part 503, improving the relative sealing between the arc-shaped pipe 3 and the extension pipe 4.

[0044] More specifically, the sealing assembly 10 includes: a fixed ring 101, which is fixedly installed at the ends of the main oil pipe 2, the extension pipe 4, and the bent pipe 6 through flanges, and the flanges are connected by bolts; a movable ring 102, which is fixedly installed at the ends of the arc-shaped pipe 3, the bent pipe 6, and the oil discharge pipe 7 through flanges, and is rotatably sleeved inside the fixed ring 101, and the movable ring 102 corresponds to the fixed ring 101 one by one; a ball bearing 103 is sleeved between the fixed ring 101 and the movable ring 102 to reduce the resistance when the movable ring 102 rotates relative to the fixed ring 101; an expansion part 104, which is communicated with the air storage part 503 through a pipe, and the pipe is not shown in the figure. The ends of the main oil pipe 2, the extension pipe 4, and the bent pipe 6 are all placed inside the expansion part 104, and the expansion part 104 is fixedly connected to the inside of the fixed ring 101. The expansion part 104 is inflated to improve the relative sealing effect between the main oil pipe 2, the extension pipe 4, and the bent pipe 6.

[0045] Specifically, the sealing assembly 10 further includes: a rotation driving part 105, which is fixedly connected to the outside of the fixed ring 101, and a driving wheel 106 is fixedly connected to the output end. The rotation driving part 105 can be a stepping motor or other components that can accurately control the rotation angle. The rotation driving part 105 is a prior art and will not be described in detail here. During use, the rotation driving part 105 is electrically connected to a corresponding controller and power supply; a driven wheel 107, which is fixedly sleeved on the outside of the movable ring 102 and meshes with the driving wheel 106, is used to adjust the rotation of the movable ring 102 relative to the fixed ring 101. During use, the movable ring 102 is rotated relative to the fixed ring 101 by controlling the rotation of the rotation driving part 105, and multiple sealing assemblies 10 work together to adjust the position of the oil discharge pipe 7.

[0046] More specifically, it also includes: a rotating part 11, which is fixedly connected to one side of the support rod 1, and the output end is fixedly connected to the top of the main oil pipe 2. The rotating part 11 can be a stepping motor or other components that can accurately control the rotation angle. The rotating part 11 is a prior art and will not be described in detail here. When in use, the rotating part 11 is electrically connected to the corresponding controller and power supply. When in use, the angle of the main oil pipe 2 relative to the support rod 1 is adjusted by the rotating part 11; a connecting pipe 12, which is rotatably sealed and connected to the lower end of the main oil pipe 2, and the other end is connected to the oil storage tank through a flange, which is convenient for the rotation of the main oil pipe 2 and improves the sealing effect between the main oil pipe 2 and the oil storage tank.

[0047] In summary, the fixed pipe 9 is installed in advance at the position of the oil outlet of the tank truck, and the tank truck is parked near the support rod 1. Then, by controlling the linear drive unit 510 to extend, the drive plate 511 pushes the pressing rod 506, and at the same time, the output end of the drive member 5052 locks the extrusion rod 508. At this time, the linear drive unit 510 extends to rotate the extension tube 4 relative to the arc tube 3, and at the same time controls the rotation of multiple rotation drive units 105 to rotate the movable ring 102 relative to the fixed ring 101. Multiple sealing components 10 work together to adjust the position of the oil unloading pipe 7 so that the oil unloading pipe 7 corresponds to the fixed pipe 9. Then, the multiple sealing components 10 cooperate or are manually operated to make the end of the oil unloading pipe 7 fit over the end of the fixed pipe 9. In this process, the end of the fixed pipe 9 contacts the end of the hook plate 803 to flip it outward and squeeze the reed 804. When the fixed pipe 9 is inserted into the appropriate position, the end of the fixed pipe 9 pushes the middle of the hook plate 803 to flip it back to its original position, and the end of the hook plate 803 is inserted into the groove 805. At this time, the fixed pipe 9 and the oil unloading pipe 7 are relatively fixed, and then the output end of the driving member 5052 is adjusted to contact the friction plate 5051, so that the movable ring 502 is fixed relative to the fixed ring 501, and the squeezing rod 508 is unlocked, and then the linear driving part 510 continues to extend, and the pressing rod 506 is pushed to flip through the driving plate 511. At this time, the elastic sheet 509 is deformed and squeezes the gas storage part 503, and at the same time, the squeezing rod 508 pulls the inner line 8092 to make the pressing ring 802 move to the side away from the fixed pipe 9. The pressing handle 801 slides and is pushed by the pressing ring 802 to flip inward, so that the pressing handle 801 is inserted into the pressing groove 806, and the fixed pipe 9 and the oil unloading pipe 7 are further fixed. At the same time, when the end of the pressing handle 801 squeezes the air storage bag 807, the monitoring module 810 is triggered, indicating that the connection between the fixed pipe 9 and the oil unloading pipe 7 is completed. The tank truck can be controlled to unload the oil, so that the oil passes through the fixed pipe 9, the oil unloading pipe 7, the bending pipe 6, the extension pipe 4, the arc pipe 3, the main oil pipe 2 and the connecting pipe 12 in sequence into the oil storage tank.

[0048] After waiting for all the remaining leaked oil in the pipeline to be transported to the oil storage tank, the oil unloading is completed, the tank truck is controlled to close the output, and then the linear drive unit 510 is reset. At the same time, the extrusion rod 508 no longer pulls the inner line 8092, so that the pressure ring 802 can be reset, and then the pressure ring 802, the pressure handle 801 and the hook plate 803 are manually reset. At this time, the oil unloading pipe 7 is unlocked relative to the fixed pipe 9, and then the oil unloading pipe 7 can be manually pulled out to complete the oil unloading.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
