[0002] The vehicle crane arm, also known as a fluid loading and unloading arm, is a specialized piece of equipment used in the petrochemical industry for fluid loading and unloading. It utilizes a rotary joint to connect rigid pipes and elbows to facilitate the transfer of liquid media between trains, tank cars, and trestle storage and transportation pipelines. This mobile device replaces traditional hose connections and offers high safety, flexibility, and a long service life. Complying with GB 50074-2002, "Petroleum Depot Design Code," this product is an ideal specialized piece of equipment for receiving and distributing oil materials. It can also be widely used in the chemical industry and other sectors to receive and distribute various liquid raw materials.

[0003] Highway oil loading and unloading cranes are specialized equipment used for loading and unloading fluids from railway tank cars and road tank trucks. They can be categorized as either top loading or bottom loading. They can transport petroleum products such as crude oil, gasoline, diesel, and lubricants; they can also transport chemical products such as concentrated sulfuric acid, liquefied natural gas, liquefied petroleum gas, molten sulfur, asphalt, and carbon disulfide.

[0004] The crane is primarily composed of fixed, rotating, operating, and balancing mechanisms, as well as oil pipes. Current vehicle cranes are difficult to align when installed at the rear end. They lack control over large flow rates, timing of large outflows, and coordination of conversion processes. When it comes to different terminal port diameters on vehicles, the crane lacks conversion components to the corresponding port diameters and related components that can adapt to emergency adjustments, making it difficult to quickly respond to different oil delivery situations and conditions. Utility Model Content

The first outer cylinder contains the first support seat, the first support seat is slidably connected to the first clutch rod, the first clutch rod is sleeved with the main pipe, and a first spring is arranged between the main pipe and the first clutch rod. When the main pipe slides, the limit hole has a limiting effect on it.

[0011] Furthermore, the first external tube includes a second outer cylinder, a second support seat, a second clutch rod, an outer tube and a second spring. The second outer cylinder contains a second support seat, the second support seat is slidably connected to the second clutch rod, the outer tube is sleeved on the second clutch rod, a second spring is arranged between the outer tube and the second clutch rod, and the outer tube is connected to the main tube through the second spring.

[0012] Furthermore, an adapter is provided on the second oil pipeline, and a spring cylinder is hingedly connected to the adapter. The spring cylinder is connected to the tail end of the second oil pipeline through a connecting transverse pipe.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0031] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] Example 1: An end-caliber emergency conversion crane pipe comprises: a column 2 and at least one multi-degree-of-freedom delivery pipe 1, wherein the column 2 is vertically arranged, and the at least one multi-degree-of-freedom delivery pipe 1 is arranged on the column 2, one end of the multi-degree-of-freedom delivery pipe 1 is connected to the column 2, and one end of the multi-degree-of-freedom delivery pipe 1 is a connection end for matching with a tank truck;

[0033] The multi-degree-of-freedom delivery pipe 1 includes a first oil delivery pipe 11, a second oil delivery pipe 12, a third oil delivery pipe 13 and an emergency multi-conversion connector 60. The first oil delivery pipe 11 is an L-shaped pipe body, the second oil delivery pipe 12 is a three-elbow pipe body, and the third oil delivery pipe 13 is a double-elbow pipe body. The horizontal end of the first oil delivery pipe 11 is connected to the column 2, the vertical end of the first oil delivery pipe 11 is connected to one end of the second oil delivery pipe 12, and the other end of the second oil delivery pipe 12 is connected to one end of the third oil delivery pipe 13. The other end of the third oil delivery pipe 13 is detachably connected to the emergency multi-conversion connector 60;

[0034] When the number of multi-degree-of-freedom delivery pipes 1 is one, one end of the multi-degree-of-freedom delivery pipe 1 is connected to the column 2, and the other end of the multi-degree-of-freedom delivery pipe 1 is the oil delivery end for the tank truck.

[0035] When there are multiple multi-degree-of-freedom delivery pipes 1, the multiple multi-degree-of-freedom delivery pipes 1 are arranged in parallel, one end of each multi-degree-of-freedom delivery pipe 1 is connected to the column 2, and the other end of each multi-degree-of-freedom delivery pipe 1 is the oil delivery end that cooperates with the tank truck, forming a multi-port simultaneous output mode, which can not only realize the large-flow output and input process, but also realize the simultaneous use of multiple ports. Each oil delivery end can also quickly convert the corresponding caliber according to the structure of the emergency multi-conversion connector 60 to realize the connection process of local adaptation caliber.

[0036] The emergency multi-conversion connector 60 includes a universal main pipe 61 and a first external pipe 62. The universal main pipe 61 is a common connector, and the first external pipe 62 is a large-diameter female connector. One end of the universal main pipe 61 is connected to the other end of the third oil pipeline 13, and the other end of the universal main pipe 61 is plugged into one end of the first external pipe 62. The other end of the first external pipe 62 is the connecting end that matches the tank truck. The first external pipe 62 is a large-diameter conveying pipe body, which is a terminal conveying component. By setting up multiple crane pipes in this way, the device can have higher adaptability and can be matched with more external machines. The first oil pipeline is an L-shaped pipe, the second oil pipeline adopts a three-elbow pipe body, and the third oil pipeline is a double-elbow pipe. The head pipe body explains its necessary connection structure, and also explains that it is connected to the first external pipe 62. The universal main pipe 61 can give more pressure. The purpose is that the universal main pipe 61 can adapt to stronger pressure. At this point, the first external pipe 62 can provide stronger pressure. As a result, the universal main pipe 61 can handle more liquid in a short time. The liquid of the first oil pipe 11 comes from the column 2 and flows out from the vertical liquid pipe through the first oil pipe 11; the liquid of the second oil pipe 12 comes from the first oil pipe 11, passes through the second oil pipe 12 and flows out from the horizontal pipe; the third oil pipe 13 comes from the second oil pipe 12, passes through the third oil pipe 13 and flows out from the vertical direction, and then flows out through the emergency multi-conversion connector 60 after turning from the vertical direction to the horizontal direction.

[0037] The working principle of the internal oil transfer process between the at least one multi-degree-of-freedom delivery pipe 1 and the column 2 in this embodiment is the same as the oil transfer process of the existing crane pipe. Other necessary components of the crane pipe not mentioned are the same as those of the crane pipe in the prior art.

[0038] In this embodiment, at least one multi-degree-of-freedom conveying pipe 1 and the column 2 are matched with each other to adapt to the downward loading and unloading conveying mode.

[0039] 613 is a main pipe 614 that is fixed to the outer wall of the main pipe 614 and is provided with a first spring 615.

[0040] Example 3: Based on Example 2, the first external tube 62 includes a second outer cylinder 621, a second support seat 622, a second clutch rod 623, an outer tube 624 and a second spring 625. The second outer cylinder 621 contains the second support seat 622, the second support seat 622 is slidably connected to the second clutch rod 623, the second clutch rod 623 is sleeved with an outer tube 624, a second spring 625 is provided between the outer tube 624 and the second clutch rod 623, and the outer tube 624 is connected to the main tube 614 through a connector 626. With this arrangement, the second outer cylinder 621 is connected to the second support seat 622, and the second support seat 622 is effectively supported, ensuring the core demand of the second support seat 622 as the overall stability. The second clutch rod 623 is fixed on the second support seat 622 as the main sliding component and the second spring 625. The second spring 625 can provide rebound force to the second clutch rod 623, so that the second clutch rod 623 has a complete rebound system after the sliding is completed, and the outer tube 624 is connected to the main tube 614 through the connector 626.

[0041] Example 4: On the basis of Example 3, an adapter 121 is provided on the second oil pipeline 12, and the adapter 121 is hinged with a spring cylinder 122. The spring cylinder 122 is connected to the tail end of the second oil pipeline 12 through a connecting cross pipe 123. With such an arrangement, the working principle of the spring cylinder 122 utilizes a spring cylinder balancer, so that the second oil pipeline 12 is easy and labor-saving to operate, and can move within the normal moving range of the crane, thereby improving the loading and unloading efficiency. When the second oil pipeline 12 is in the accommodated state, the crane can reduce the space occupied by the crane, which is convenient for management and operation.

[0042] Example 5: On the basis of Example 4, the third oil pipeline 13 is provided with a second external pipe 14. The second external pipe 14 is a small-diameter female connector. The structure of the second external pipe 14 is consistent with that of the first external pipe 62. One end of the second external pipe 14 is detachably connected to the universal main pipe 61, and the other end of the second external pipe 14 is a narrow-mouth connection end. With this arrangement, the second external pipe 14 is our small flow port, which is replaced when we use a small flow. When the first external pipe 62 needs to be replaced to the head of the second external pipe 14, the first external pipe 62 is returned to the existing position to replace the second external pipe 14. It is very convenient to use and effectively improves efficiency.

[0043] Example 6: Based on Example 5, a liquid phase inlet flange 3 is provided on the column 2, and the column 2 outputs or inputs gas through the liquid phase inlet flange 3. With such a configuration, the liquid phase inlet flange 3 is the joint of the column 2, and the liquid phase inlet flange 3 becomes the main vent when the column 2 needs to be replaced internally.

[0044] Example 7: On the basis of Example 6, the third oil pipeline 13 is provided with a gas phase emergency pull-off valve 63, and the gas phase emergency pull-off valve 63 is arranged at one end of the third oil pipeline 13 away from the first external pipe 62. In this way, a gas phase emergency pull-off valve 63 is provided on the third oil pipeline 13 to prevent errors from occurring during emergency closure, resulting in emergency supply errors.

[0045] Example 8: Based on Example 7, the tail ends of the first outer cylinder 611 and the second outer cylinder 621 are processed with external threads 64, and the tail end of the third oil pipe 13 is provided with internal threads 65. The external threads 64 cooperate with the internal threads 65 to lock the first outer cylinder 611 and the second outer cylinder 621 and the third oil pipe 13. Such a setting and the setting of the spiral line can make it easier for the operator to replace the first outer cylinder 611 and the second outer cylinder 621.

[0046] Example 9: Based on Example 8, the universal shaft 66 of the first oil pipeline 11 rotates along the axial direction of the second oil pipeline 12. With this arrangement, the universal shaft 66 can more accurately provide the task to be completed.

[0047] Working process:

[0048] First, the crane pipe should be assembled. First, install its main body and install multiple free delivery pipes 1 on the column 2. The specific steps are as follows: the first oil pipeline 11 is installed on the column 2, so that a channel from the column 2 to the first oil pipeline 11 is formed. Then the gas flows into the second oil pipeline 12 through the first oil pipeline 11, and then flows into the third oil pipeline 13 through the second oil pipeline 12. The liquid flows into the universal main pipe 61, flows in quickly through the universal main pipe 61, and finally flows out through the two joints of the universal main pipe 61 and the first external pipe 62. In the process of outflow, this experiment adopts the universal main pipe 61. The main pipe 61 and the first external pipe 62 can avoid damage to the control kit due to the rigid structure, thereby causing damage. The universal main pipe 61 is used, and the first external pipe 62 can be stable and sealed in the connection state. When the first external pipe 62 is connected to the universal main pipe 61, it can quickly extend the retaining spring to the other party, and the universal main pipe 61 can receive the retaining spring at the same time to form an emergency and quick connection method between the first external pipe 62 and the universal main pipe 61. This connection method is more secure and reliable, easy to disassemble, and is conducive to the establishment and promotion of emergency and quick transportation methods.

[0049] Working mode 1: When each multi-free transport pipe 1 is used for large-flow and large-caliber transport, it is only necessary to install the first external pipe 62 corresponding to the installed universal main pipe 61 to realize the configuration of the terminal large-caliber output structure.

[0050] Working mode 2: When each multi-free transport pipe 1 is used for large-flow and large-caliber transport, it is only necessary to install a second external pipe 14 corresponding to the installed universal main pipe 61 to realize the configuration of the terminal small-caliber output structure.

[0051] For the multi-free transport pipe 1 that has been installed with the first external pipe 62, when performing the terminal interface conversion, it is only necessary to remove the first external pipe 62 from the universal main pipe 61 and install the second external pipe 14 to the universal main pipe 61 to realize the conversion process from large-diameter to small-diameter output structure.

[0052] For the multi-free transport pipe 1 that has been installed with the second external pipe 14, when converting the terminal interface, it is only necessary to remove the second external pipe 14 from the universal main pipe 61 and install the first external pipe 62 on the universal main pipe 61 to realize the conversion process from small-diameter to large-diameter output structure.
