Description

Technical Field

[0001] The invention relates to the technical field of automatic loading and lowering crane pipes, in particular to an automobile gas-liquid phase double-tube automatic loading and lowering crane pipe. Background Art

[0002] The dual-tube automatic loading and unloading crane for gas and liquid phases is a specialized device for loading and unloading tank trucks. It is widely used in the petroleum, chemical, and other industries, suitable for loading and unloading a variety of liquid materials. It operates in a wide range of temperatures, from ambient to high, and can be used for liquid material loading operations in tank farms and material yards. It connects to the tank truck interface and guides the material into the tank. This ensures smooth material flow and prevents accidents such as leaks. The liquid phase crane is used to transport liquid oil products, while the gas phase crane is used for oil and gas recovery.

[0003] When the gas phase crane pipe and the liquid phase crane pipe are connected to the slot of the car, the quick connectors of the gas phase crane pipe and the liquid phase crane pipe need to be connected to the corresponding slots of the car respectively, so that each corresponding slot of the car can be inserted into the gas phase quick connector or the liquid phase quick connector. With the development of intelligent machinery in my country, the existing technology has realized the connection of the gas phase or liquid phase quick connector to the car slot through automated equipment. It first realizes the rough alignment of the gas phase quick connector or the liquid phase quick connector with the car slot through a three-dimensional support mechanism, and then drives the gas phase quick connector or the liquid phase quick connector to the car slot fine alignment through an electric cylinder. In actual operation, gas phase quick connector or liquid phase quick connector needs to be aligned with the car slot. The gas or liquid quick connector is docked with the automobile slot at the center of each other. However, due to different automobile models, different slot angles, or different terrains of the ground where the automobile is parked, the position deviation of the automobile slot is easily caused during the precise alignment process. The docking of the gas or liquid quick connector with the automobile slot requires high precision. The existing technology pushes the gas or liquid quick connector in a straight line during the precise alignment process. If the gas or liquid quick connector and the automobile slot have a slight position deviation and are no longer on the same center line, it will make it difficult to connect the gas or liquid quick connector and the automobile slot, and manual adjustment will be required, which is very troublesome.

[0045] Gas phase-fine alignment, the gas phase electric cylinders 6 on both sides extend respectively, the telescopic end of the gas phase electric cylinder 6 passes through the connecting hole 37, and when the nut in front of the telescopic end of the gas phase electric cylinder 6 presses against the connecting hole 37, the gas phase electric cylinder 6 pushes the fine alignment flange 33 to move forward, and the fine alignment flange 33 drives the fine alignment guide tube 35, the fixed flange 43 and the gas phase quick connector body 44 to move forward, and the guide sleeve 39 slides on the connecting sleeve 40, and the tapered hole 36 gradually leaves the tapered positioning shaft 20. Since the tapered end of the tapered positioning shaft 20 is gradually located at the gradually thickening end of the tapered hole 36, the tapered hole 36 is on the tapered positioning shaft 20. The movable gap on the conical limit rod 19 gradually becomes larger. Similarly, the guide hole 34 gradually leaves the conical limit rod 19, and the movable gap of the guide hole 34 on the conical limit rod 19 gradually becomes larger. Due to the existence of the free gap and the gravity of the gas phase vertical tube 2 itself and the elastic support of the compression spring 27 and the tension spring 32, the gas phase quick connector body 44 can adapt to the position deviation when docking with the automobile slot, and the overall position and angle can be adjusted by itself. When the automobile slot is docked to the inside of the gas phase quick connector body 44, if the center line of the gas phase quick connector body 44 is higher than the center line of the automobile slot, the spring fixing plate 28 will be separated from the compression spring 27. At this time, the compression spring 27 does not work, and the tension spring 32 is in a stretched state. As the automobile notch is guided by the arc-shaped inner wall of the gas phase quick connector body 44, the tension spring 32 pulls the gas phase quick connector body 44 downward, so that the automobile notch and the gas phase quick connector body 44 can be flexibly adjusted to dock. If the center line of the gas phase quick connector body 44 is lower than the center line of the automobile notch, it means that the height of the gas phase quick connector body 44 is too low, and the precise alignment guide tube 35, the gas phase elbow 38 and other components drive the spring fixing plate 28 to press down. At this time, the compression spring 27 is pressed down by the spring fixing plate 28, and the compression spring 27 provides elastic force to press the gas phase quick connector body 44. The quick connector body 44 is pushed up, and since there is a large space for movement at the connection between the hook end of the lower part of the tension spring 32 and the U-bolt 29, the tension spring 32 is not affected by the pressure when it is lowered. At this time, the tension spring 32 does not work. Similarly, after adjustment, under the arc-shaped guide of the inner wall of the gas phase quick connector body 44, the gas phase quick connector body 44 is finally flexibly docked with the center of the automobile notch. When docking is good, the gas phase motor 48 drives the lock tongue 50 to rotate in the lock tongue hole 51, so that the automobile notch in the gas phase quick connector body 44 is locked by the lock tongue 50, completing the fixation of the gas phase quick connector body 44 and the automobile notch.

[0046] It is worth pointing out that the electric drive equipment in this case is electrically connected to the PLC control system of the crane pipe and is controlled by the PLC control system.

[0047] It is worth pointing out that since the gas phase quick connector body 44 and the precision alignment guide tube 35, gas phase elbow 38 and other parts connected thereto have a gravity tendency when they are positioned downward, in order to adjust their upward movement and overcome gravity, a compression spring 27 with a large elastic coefficient is required to act on them. When the gas phase quick connector body 44 and the precision alignment guide tube 35, gas phase elbow 38 and other parts connected thereto are positioned upward, they do not need to overcome too much gravity when they are pulled down for adjustment, so a tension spring 32 with a smaller elastic coefficient is required to act on them when they are pulled down.

[0048] It is worth pointing out that the main body 44 of the gas phase quick connector and the precision alignment guide tube 35 and the gas phase elbow 38 connected thereto may be leftward, rightward, upward or downward relative to the automobile slot when they are actually docked. The above schemes can all be adaptively adjusted by themselves, and even the main body 44 of the gas phase quick connector and the precision alignment guide tube 35 and the gas phase elbow 38 connected thereto can be rotated at a slight angle, which will not be described in detail here.

[0049] In the liquid phase connection, since the core principles and execution actions are the same as those of the gas phase connection, they will not be explained here. This article will only explain the connection between the liquid phase quick connector assembly and the automobile slot. When the API dry separation valve body 54 is precisely connected with the automobile slot, the electric push rod 56 pushes the handle safety operating rod 58, and the handle safety operating rod 58 pushes the U-shaped handle 59 to lock with the automobile slot, and then drives the motor 60 to drive the handle rod 62, the handle rod 62 drives the handle sleeve 63, and the handle sleeve 63 drives the valve lever 64 to rotate, so that the API dry separation valve body 54 is opened.

[0050] The present invention is simple to operate, easy to use, and suitable for comprehensive promotion and application. Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
