Description
Technical Field
[0001] This utility model belongs to the technical field of loading and unloading arms, specifically relating to a fully automatic intelligent loading and unloading arm. Background Technology
[0002] Loading arms are key pieces of equipment in the petrochemical storage and transportation sector, used for open-top unloading operations from trucks. Traditional loading arms typically consist of a rotating base, telescopic arm, swivel joint, and piping system, employing an adjustable spring balancing system. Operators must manually control the loading arm to connect to the tank truck opening.
[0003] The existing technology has at least the following drawbacks: operators need to climb onto the roof for manual docking, which poses a risk of falling from height and exposure to hazardous chemicals; some manufacturers use a sliding table structure, which requires the installation of a bellows cover for protection, but it is susceptible to dust intrusion in outdoor environments, leading to mechanical failure; maintenance is difficult, as key components such as rotary joints and telescopic arms are prone to accumulating contaminants and require frequent maintenance (the sealing ring needs to be replaced every 5,000 operations); positioning accuracy is low, relying on manual visual positioning, resulting in large errors and easy leakage of media (the standard requires the error to be controlled within ±5mm). Utility Model Content
[0004] The purpose of this utility model is to provide a fully automatic intelligent loading and unloading arm to solve the problems mentioned in the background art.

A second servo electric cylinder is fixedly installed on one side of the second liquid phase arm pipe. A connecting frame is hinged to the piston end of the second servo electric cylinder. The connecting frame is fixedly installed on the first connecting bend pipe. A conical sealing cap is sleeved on the vertical pipe.
[0006] In one preferred embodiment, the servo drive assembly consists of a servo motor, a worm gear, and a worm wheel.
[0007] In a preferred embodiment, the first servo electric cylinder has a built-in torque sensor.
[0008] In one preferred embodiment, a connecting rod is fixedly connected to one side of the first connecting bend, and an oil receiving box is fixedly installed at one end of the connecting rod.
[0009] In a preferred embodiment, a gas phase pipeline is fixedly installed on one side of the liquid phase pipeline.

Detailed Implementation
[0014] The present invention will be further described below with reference to the embodiments.
[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0016] Please see Figure 1-6This utility model provides a fully automatic intelligent loading and unloading arm, including a column 1, a control box 15 mounted on the front of the column 1, a first support square tube 2 rotatably connected to the top of the column 1, a second support square tube 3 rotatably connected to the top of the first support square tube 2, a bracket 4 fixedly mounted at one end of the second support square tube 3, and a vision camera 5 fixedly mounted at one end of the bracket 4. Servo drive components 6 are provided on both the column 1 and the first support square tube 2, respectively driving the first support square tube 2 and the second support square tube 3 to rotate. A liquid phase pipeline 7 is provided on one side of the column 1, and a gas phase pipeline 14 is fixedly mounted on one side of the liquid phase pipeline 7. The liquid phase pipeline 7 includes a liquid phase pipeline fixedly mounted on the back of the column 1. A liquid phase inlet pipe 71 is rotatably connected to a first liquid phase arm pipe 72 at its upper end. A first connecting bend pipe 73 is rotatably connected to one end of the first liquid phase arm pipe 72. A second liquid phase arm pipe 74 is rotatably connected to one end of the first connecting bend pipe 73. A second connecting bend pipe 75 is rotatably connected to one end of the second connecting bend pipe 75. A vertical pipe 76 is fixedly connected to one end of the second connecting bend pipe 75. A first servo electric cylinder 8 is fixedly installed between the bracket 4 and the end of the second liquid phase arm pipe 74 near the second connecting bend pipe 75. A second servo electric cylinder 9 is fixedly installed on one side of the second liquid phase arm pipe 74. A connecting frame 10 is hinged to the piston end of the second servo electric cylinder 9. The connecting frame 10 is fixedly installed on the first connecting bend pipe 73. A conical sealing cap 11 is fitted onto the pipe 76. The conical sealing cap 11 is made of fluororubber material with a Shore hardness of 70° and adaptively compensates for an angle of 5-15°. Through the arrangement of the first supporting square pipe 2, the second supporting square pipe 3, the bracket 4, the vision camera 5, the servo drive assembly 6, the liquid phase pipeline 7, the first servo electric cylinder 8, the second servo electric cylinder 9, the connecting frame 10, and the conical sealing cap 11, during operation, the control box 15 receives a signal from the loading system and activates the two servo drive assemblies 6 to rotate the first supporting square pipe 2 and the second supporting square pipe 3, adjusting the liquid phase pipeline 7 and moving the vertical pipe 76 to the preset coordinates. Then, the vision camera 5 acquires an image of the tank opening, and the AI algorithm outputs a 3D coordinate system. The correction values (Δx, Δy, Δz) are used to adjust the position of the vertical tube 76 of the liquid phase pipeline 7 via the servo drive component 6. Then, the first servo electric cylinder 8 can be activated to press down at a speed of 50 mm / s. The first servo electric cylinder 8 drives the end of the second liquid phase arm tube 74 near the second connecting bend 75 to rotate downward, thereby driving the lower end of the vertical tube 76 to gradually extend into the tank opening. Finally, the vertical tube 76 drives the conical sealing cap 11 to be inserted into the tank opening for sealing. When the torque sensor detects ≥200 N•m, it stops and feeds back a sealing completion signal. During recovery, the system ends with a signal received, and the first servo electric cylinder 8 retracts at a speed of 80 mm / s. At the same time, the servo drive component 6 drives the liquid phase pipeline 7 to fold back into position.
[0017] Specifically, the servo drive assembly 6 consists of a servo motor, a worm gear, and a worm wheel. By setting the servo drive assembly 6, the servo motor can be started to drive the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel can then drive the first connecting bend 73 or the second connecting bend 75 to rotate horizontally, with a torque ≥2000 N•m.
[0018] Among them, the vision camera 5 uses a 4-megapixel industrial camera, paired with a deep learning algorithm, with a recognition time of <0.5s and a sampling frequency of 30fps.
[0019] The first liquid phase arm tube 72 is 1.5m long, made of carbon steel, and has a rotation angle of 0-180°. The second liquid phase arm tube 74 is 1.2m long, made of carbon steel, and has a rotation angle of 0-180°.
[0020] The first servo electric cylinder 8 has a thrust of 200 kg and a stroke of 2200 mm. The first servo electric cylinder 8 has a built-in torque sensor (accuracy ±1%FS).
[0021] One side of the first connecting bend 73 is fixedly connected to a connecting rod 12, and one end of the connecting rod 12 is fixedly installed with an oil receiving box 13. Due to the setting of the oil receiving box 13, when the connection is sealed, the first connecting bend 73 and the second liquid phase arm tube 74 rotate relative to each other, and the first connecting bend 73 will drive the oil receiving box 13 to move away automatically through the connecting rod 12 (response time <2s). After the vertical tube 76 is retracted, the oil receiving box 13 will automatically move to the bottom of the vertical tube 76.
[0022] The working principle and usage process of this utility model are as follows: First, during operation, the control box 15 receives a signal from the loading system and activates two servo drive components 6 to rotate the first support square tube 2 and the second support square tube 3, adjusting the liquid phase pipeline 7 and moving the vertical tube 76 to the preset coordinate position. Then, the vision camera 5 acquires an image of the tank opening, and the AI algorithm outputs three-dimensional coordinate correction values (Δx, Δy, Δz). The servo drive components 6 then adjust the position of the vertical tube 76 of the liquid phase pipeline 7. Finally, the first servo electric cylinder can be activated. The first servo cylinder 8 presses down at a speed of 50 mm / s, driving the second liquid phase arm tube 74 to rotate downwards near the end of the second connecting bend 75, thereby driving the lower end of the vertical tube 76 to gradually extend into the tank opening. Finally, the vertical tube 76 drives the conical sealing cap 11 to be inserted into the tank opening for sealing. When the torque sensor detects ≥200 N•m, it stops and sends back a sealing completion signal. During recovery, it receives a system end signal, and the first servo cylinder 8 retracts at a speed of 80 mm / s. At the same time, the servo drive assembly 6 drives the liquid phase pipeline 7 to fold back into place.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
