Description

Technical Field

[0001] The present invention relates to the technical field of crane pipes, and in particular to an automatic truck unloading system. Background Art

[0002] In the fields of petrochemicals, warehousing and logistics, the unloading of liquid media (such as finished oil and chemical raw materials) by tank trucks through a crane system is a core operating process. Traditional crane unloading systems are usually composed of multiple sections of rotatable pipes, quick connectors and manual locking mechanisms.

[0003] For example, a crane pipe leak test system for liquid chlorine unloading with application number 202411804253.4 includes a fixed pipe and a movable pipe, and an insulation structure is arranged on the fixed pipe and the movable pipe; the insulation structure is used to insulate the inside of the fixed pipe and the movable pipe; a temperature detection component for obtaining the temperature of the insulation structure is arranged on the 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 component is arranged on the fixed pipe, and the gas thermal imaging component forms a gas detection area, and the gas detection area covers the movable pipe.

[0004] There are some problems with the above technical solution and the traditional unloading system during use. In actual application, the connection fixation reliability is insufficient, and there is a lack of connection status detection mechanism, which easily causes leakage at the connection position. The sealing performance of multiple pipelines is weak, and with long-term use, it is easy to cause seal failure due to wear. The connection between the crane pipe and the tank truck pipeline is mostly manually operated, which wastes human resources. In addition, the crane pipe itself is heavy and inconvenient for personnel to operate.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention effectively achieves the purpose of improving the stability of pipeline connection by providing a connecting component and a fixed pipe. During 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 cause it to flip and squeeze the spring. When the fixed pipe is inserted into the appropriate position, the end of the fixed pipe pushes the middle part of the hook plate to flip and reset it. At the same time, the spring further pushes the hook plate, causing the end of the hook plate to insert into the groove. At this time, the fixed pipe and the oil unloading pipe are relatively fixed, and the pressing handle is flipped inward by the pressing ring and inserted into the pressing groove, further fixing the fixed pipe and the oil unloading pipe, improving stability. Through multiple connection methods, the oil unloading pipe is stable and sealed relative to the fixed pipe, avoiding safety accidents caused by oil leakage during the oil unloading process.

[0019] 2. The present invention adds a function of connection status detection by providing a pressing handle, a pressing ring, an air storage bag and a monitoring module. 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 fixed pipe and the oil unloading pipe are not effectively connected, and the tank truck cannot unload oil, thereby achieving the purpose of monitoring whether the pipeline is tightly connected and improving the safety of oil unloading; 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 connection between the fixed pipe and the oil unloading pipe is complete, and the tank truck can be controlled to unload oil, helping the operator to confirm whether the locking is in place and reducing the risk of misjudgment.

[0020] 3. The present invention optimizes the sealing effect between multiple pipes by setting a sealing rotating assembly and a sealing assembly. When the output end of the driving part contacts the friction disk, the linear driving part pushes the pressing rod to flip through the driving plate, and the extrusion rod is rotated synchronously through the pushing rod. At this time, the elastic sheet deforms and squeezes the air storage part, thereby improving the relative sealing between the arc tube and the extension tube. The air storage part is connected to the expansion part 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 tube, and the bending tube.

[0021] 4. The present invention effectively reduces the labor pressure of personnel by providing a linear drive part, a rotary drive part, a drive wheel and a driven wheel. When in use, the linear drive part is controlled to extend to rotate the extension tube relative to the arc tube, and the multiple rotary drive parts are controlled to rotate at the same time to rotate the movable ring relative to the fixed ring. Multiple sealing components work together to adjust the position of the oil unloading pipe so that the oil unloading pipe corresponds to the fixed pipe, and then the end of the oil unloading pipe is sleeved on the end of the fixed pipe, reducing the distance that the crane pipe is manually pulled, reducing working pressure, and avoiding wear of the sealing components between the pipes due to the relative rotation of multiple pipes and the imbalance of manual pulling force when the crane pipe is manually pulled.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The present invention provides Figures 1 to 101. An automatic unloading system shown in FIG. 1 includes a support rod 1, which is fixed to the ground, and 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, and one end of the main oil pipe 2 is connected to the storage tank. The main oil pipe 2 can rotate relative to the support rod 1, and the main oil pipe 2 is T-shaped and has a hollow structure; an arc pipe 3, which is rotatably connected to the other end of the main oil pipe 2, and the arc pipe 3 is bent 90 degrees in an L shape; an extension pipe 4, which is rotatably connected to the other end of the arc pipe 3, and the extension pipe 4, the arc pipe 3, and the main oil pipe 2 are connected in sequence, and the extension pipe 4 is bent in a Z shape; a sealing rotating assembly 5, which is rotatably connected between the arc pipe 3 and the extension pipe 4, and is used to detect the sealing of the pipeline connection position; a bending pipe 6, which is rotatably connected to the end of the extension pipe 4, and the bending pipe 6 is bent 90 degrees; oil unloading The tube 7 is rotatably connected to the end of the bent tube 6, and the other end of the tube is provided with a connecting assembly 8. The oil unloading tube 7, the bent tube 6, and the extension tube 4 are connected in sequence. The connecting assembly 8 includes: a pressure handle 801, which is rotatably connected to the outside of the oil unloading tube 7, and multiple pressure handles are evenly arranged; a pressure ring 802, which is sleeved on the outside of the oil unloading tube 7 and contacts multiple 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, so that the pressure handle 801 is flipped and fixed. After the pressure ring 802 is reset, the pressure handle 801 needs to be manually reset; a fixed tube 9, which is installed at the oil outlet position of the tank truck. The end of the fixed tube 9 is pre-installed at the oil outlet position of the tank truck through a flange. The oil unloading tube 7 can be connected to the fixed tube 9, and the relative position of the oil unloading tube 7 and the fixed tube 9 is locked by the connecting assembly 8.

[0035] It should be noted that the oil outlet of the tank truck is equipped with a control valve, which can autonomously control whether to unload oil, avoid oil leakage in the tank truck, and control the tank truck to unload oil at the right time.

[0036] The end of the hook plate 803 is inserted into the groove 805, and the fixed tube 9 and the oil unloading tube 7 are relatively fixed.

[0037] More specifically, it also includes a pressing groove 806, which corresponds to the pressing handle 801 one-to-one and is opened on the outside of the fixed tube 9. During use, the pressing handle 801 is pushed by the pressure ring 802 to flip inward, so that the pressing handle 801 is inserted into the pressing groove 806, further fixing the fixed tube 9 and the oil unloading tube 7, and improving stability; the air storage bag 807 is fixedly sleeved on the outside of the oil unloading tube 7, and the end of each pressing handle 801 can press the air storage bag 807, and the monitoring module 810 is fixedly connected to the middle of the oil unloading tube 7 for monitoring the air pressure of the air storage bag 807. The monitoring module 810 is an air pressure sensor or a micro-sensor for monitoring the pressure in the air storage bag 807 or the deformation of the air storage bag 807. When the fixed rod is fixedly connected to the oil unloading tube 7 by the pressing handle 801, the end of the pressing handle 801 squeezes the air storage bag 807 to trigger the monitoring module 810, indicating that The fixed pipe 9 is connected to the oil unloading pipe 7, and the tank truck can be controlled to unload oil; if the pressure handle 801 and the pressure groove 806 do not correspond, the pressure handle 801 cannot be flipped to the state of squeezing the air bag 807, the monitoring module 810 will not be triggered, and the surface fixed pipe 9 is not connected to the oil unloading pipe 7, and the tank truck cannot unload oil, thereby improving the safety of oil unloading and achieving the purpose of monitoring whether the pipeline is tightly connected, thereby avoiding leakage caused by unloading oil when the pipeline is not tightly connected; the pull rod 808 is fixedly connected to one side of the pressure ring 802, and multiple pull rods 808 are evenly arranged, and the pull rod 808 is slidably matched with the oil unloading pipe 7; the pull wire 809, one end of which is fixedly connected to multiple pull rods 808, and the other end is connected to the sealing rotating assembly 5, and the sealing rotating assembly 5 uses the pull wire 809 to make the pull rod 808 pull the pressure ring 802 to move, forcing the pressure handle 801 to rotate and lock the oil unloading pipe 7 and the fixed pipe 9.

[0038] 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 unloading 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.

[0039] It should be pointed out that after the oil unloading is completed, the pull wire 809 needs to be loosened to allow the pressure ring 802 to be reset, and then the pressure handle 801 and the hook plate 803 are manually reset to unlock the fixed pipe 9 and the oil unloading pipe 7, and manually separate them to complete the oil unloading work.

[0040] Specifically, the connection positions of the bent pipe 6 and the oil unloading pipe 7 and the extension pipe 4 and the connection positions of the arc pipe 3 and the main oil pipe 2 are all provided with sealing components 10, which are used to improve the sealing performance of the pipeline connection positions.

[0041] More specifically, the sealing rotation assembly 5 includes: a fixed ring 501, which is fixedly connected to the end of the arc tube 3 through a flange; a movable ring 502, which is rotatably sleeved on the outside of the fixed ring 501 and fixedly connected to the end of the extension tube 4 through a flange, and 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; an air storage part 503, which is sleeved in the fixed ring 501, and the contact position between the arc tube 3 and the extension tube 4 is placed on the inner side of the air storage part 503. When the air storage part 503 is pressurized and expanded, it can squeeze the connection position between the arc 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 has a locking mechanism in the middle. Device 505 is used to lock the relative position of the movable ring 502 and the fixed ring 501; the locking device 505 includes a friction disk 5051, which is fixedly mounted on the outer side of the movable ring 502 and has a rough frosted surface on one side; a driving member 5052 is fixedly connected to the middle part of the support frame 504, and the output end can contact with the friction disk 5051. The driving member 5052 is a linear motor, an electromagnetic push rod or a hydraulic rod, etc., which can realize the linear movement of the output end. When in use, the driving member 5052 is electrically connected to the corresponding controller and power supply, and its output end is fixedly connected to a friction plate that can contact with the friction disk 5051. The movable ring 502 and the fixed ring 501 are relatively fixed through their mutual friction.

[0042] Specifically, the sealing rotating assembly 5 also includes: a pressing rod 506, which is rotatably connected to the upper end of the support frame 504, and the middle part is rotatably connected to the push rod 507, and the upper end of the pressing rod 506 is fixedly connected to the cylindrical boss; an extrusion rod 508, which is rotatably connected to the upper end of the support frame 504, and the middle part is rotatably connected to the push rod 507, and an elastic sheet 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 turned over and the extrusion rod 508 is turned downward through the push rod 507. At this time, the elastic sheet 509 is compressed and deformed; the fixing ring 501 corresponds to the elastic sheet 509. There is a notch at the position of the elastic sheet 509, and the pressure on the elastic sheet 509 can squeeze the air storage part 503, and when the elastic sheet 509 is under pressure, it can only bend to the side close to the air storage part 503, so that the air storage part 503 is under pressure; the linear drive part 510 is rotatably connected to the outside of the extension tube 4, and the output end is fixedly connected to the drive plate 511, and the end of the pressing rod 506 is slidably matched with the drive plate 511. The linear drive part 510 is a component that can be extended linearly, such as a linear cylinder or a hydraulic rod. During use, the linear drive part 510 is connected to the corresponding controller and power supply.

[0043] It should be noted that when the friction plate at the output end of the driving member 5052 is not in contact with the friction disk 5051, one side of the friction plate is in contact with the position where the extrusion rod 508 rotates relative to the support frame 504, and generates friction with the extrusion rod 508, so that the extrusion rod 508 is fixed relative to the support frame 504, and the extrusion rod 508 cannot rotate at this time.

[0044] During use, the output end of the adjustment drive member 5052 is not in contact with the friction plate. At this time, the linear drive part 510 is controlled to extend, and the drive plate 511 pushes the pressing rod 506. However, since the output end of the drive member 5052 locks the extrusion rod 508, the linear drive part 510 extends to rotate the extension tube 4 relative to the arc tube 3, and adjusts the position of the oil unloading tube 7 relative to the fixed tube 9; when the output end of the drive member 5052 contacts the friction plate 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 drive part 510 pushes the pressing rod 506 to flip through the drive plate 511, and the extrusion rod 508 rotates synchronously through the push rod 507. At this time, the elastic sheet 509 deforms and squeezes the air storage part 503, thereby improving the relative sealing between the arc tube 3 and the extension tube 4.

[0045] More specifically, the sealing assembly 10 includes: a fixed ring 101, which is fixedly mounted on 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 mounted on the ends of the arc pipe 3, the bent pipe 6, and the oil unloading pipe 7 through flanges, and is rotatably mounted on the inner side of the fixed ring 101, and the movable ring 102 corresponds one to one to the fixed ring 101; a ball bearing 103 is mounted between the fixed ring 101 and the movable ring 102, which is used to reduce the resistance of the movable ring 102 when it rotates relative to the fixed ring 101; an expansion part 104, which is connected to the air storage part 503 through a pipeline, and the pipeline 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 on the inner side of the expansion part 104, and the expansion part 104 is fixedly connected to the inner side 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.

[0046] Specifically, the sealing assembly 10 also includes: a rotating drive unit 105, which is fixedly connected to the outside of the fixed ring 101, and the output end is fixedly connected to a driving wheel 106. The rotating drive unit 105 can be a stepping motor or other components that can accurately control the rotation angle. The rotating drive unit 105 is a prior art and will not be described in detail here. When in use, the rotating drive unit 105 is electrically connected to the corresponding controller and power supply; a driven wheel 107, which is fixedly sleeved on the outside of the movable ring 102 and engages with the driving wheel 106 to adjust the rotation of the movable ring 102 relative to the fixed ring 101. When in use, the movable ring 102 is rotated relative to the fixed ring 101 by controlling the rotation of the rotating drive unit 105. Multiple sealing assemblies 10 work together to adjust the position of the oil unloading pipe 7.

[0047] 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, and the angle of the main oil pipe 2 relative to the support rod 1 is adjusted by the rotating part 11 during use; 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 facilitates the rotation of the main oil pipe 2 and improves the sealing effect between the main oil pipe 2 and the oil storage tank.

[0048] 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 part 510 to extend, the drive plate 511 pushes the pressing rod 506, and at the same time, the output end of the drive part 5052 locks the extrusion rod 508. At this time, the linear drive part 510 extends to rotate the extension pipe 4 relative to the arc tube 3, and at the same time controls the multiple rotation drive parts 105 to rotate to rotate the movable ring 102 relative to the fixed ring 101. The 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 make it flip 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 tube 9 and the oil unloading tube 7 are relatively fixed. 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 extrusion rod 508 is unlocked. Then, the linear driving part 510 is extended, and the pressing rod 506 is pushed to turn over through the driving plate 511. At this time, the elastic sheet 509 is deformed and squeezes the gas storage part 503. At the same time, the extrusion rod 508 pulls the inner line 8092 to make the pressure ring 802 move away from the fixed tube 9. The pressing handle 801 slides and is pushed by the pressure ring 802 to flip inward, so that the pressing handle 801 is inserted into the pressure groove 806, further fixing the fixed tube 9 and the oil unloading tube 7. 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 tube 9 and the oil unloading tube 7 is completed, and the tank truck can be controlled to unload the oil, so that the oil passes through the fixed tube 9, the oil unloading tube 7, the bending tube 6, the extension tube 4, the arc tube 3, the main oil tube 2 and the connecting tube 12 in sequence into the oil storage tank.

[0049] After waiting for all the remaining leaked oil in the pipeline to be transported to the oil storage tank, the oil unloading is completed, and the tank truck is controlled to shut down the output. The linear drive unit 510 is then reset, and the extrusion rod 508 no longer pulls the inner line 8092, so that the pressure ring 802 can be reset. The pressure ring 802, the pressure handle 801 and the hook plate 803 are then manually reset. At this time, the oil unloading pipe 7 is unlocked relative to the fixed pipe 9, and the oil unloading pipe 7 can then be manually pulled out to complete the oil unloading.
