[0002] A crane hose is a retractable and movable pipe, mostly used for loading and unloading liquids at petroleum and chemical terminals, with media such as oil and water inside. It comes in many different types and offers advantages over conventional hoses, such as increased safety and flexibility.

[0003] The crane pipe is mainly composed of fixed, rotating, operating, balancing and other mechanisms and oil pipes. The rotating mechanism (rotating joint) is carefully made of forged steel or aluminum alloy, equipped with double-row ball bearings and special stainless steel sealing rings. It has flexible rotation, reliable sealing performance and durability.

[0004] After the crane pipe is used, the vertical pipe is pulled out of the tank mouth of the tank truck, and a lot of liquid remains in the vertical pipe. The residual liquid often drips onto the ground or equipment under the action of gravity. The existing treatment method is to use a liquid receiving bucket to collect and process the residual liquid in the vertical pipe. However, the existing liquid receiving bucket has a relatively simple function and poor flexibility. The specific position of the liquid receiving bucket cannot be adjusted according to needs, resulting in the inability to accurately receive liquid. Moreover, the installation position of many liquid receiving buckets limits the up and down pitching movement of the crane pipe outer arm. For this purpose, a swing-arm top liquid loading and unloading pneumatic liquid receiving bucket device is provided. Utility Model Content

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0022] Example: See Figure 1-6 The utility model provides a technical solution: a swing arm type pneumatic liquid receiving hopper device for top liquid loading and unloading, comprising an inner arm 18 of a liquid loading and unloading arm, an outer arm 19 of a liquid loading and unloading arm, a vertical pipe 21 and a curved pipe 24. The inner arm 18 of the liquid loading and unloading arm is connected to the curved pipe 24 through a second rotary joint 22. The curved pipe 24 is connected to the outer arm 19 of the liquid loading and unloading arm through a third rotary joint 23. The outer arm 19 of the liquid loading and unloading arm is connected to the vertical pipe 21 through a first rotary joint 20. A support is installed on the second rotary joint 22. 6 is installed at one end of a 180-degree swing cylinder 11, a bearing seat 13 is installed on the top of the 180-degree swing cylinder 11, a liquid collecting hopper height adjustment vertical beam 17 is installed on the bearing seat 13, a positioning clamp 16 is installed on the liquid collecting hopper height adjustment vertical beam 17, a gyration radius adjustment crossbeam 15 is installed on the positioning clamp 16, a gyration radius adjustment crossbeam 15 is installed on one end of the gyration radius adjustment crossbeam 15, a liquid collecting hopper bracket 8 is installed on the liquid collecting hopper bracket 8, and a liquid collecting hopper 9 is installed on the bottom of the liquid collecting hopper 9. A single-station pneumatic valve 10 is installed at the bottom of the liquid collecting hopper 9.

[0023] The 180-degree swing cylinder 11 is connected to the control valve group 1 in the air control box assembly 3 through the air pipeline 4, and a speed regulating valve 2 is installed on the air pipeline 4.

[0024] One end of the support 6 is mounted on the second rotary joint 22 through the mounting bolt 5. A rotating shaft 12 is mounted on the 180-degree swing cylinder 11. The rotating shaft 12 passes through the bearing seat 13 and is connected to the liquid collecting hopper height adjustment vertical beam 17. The 180-degree swing cylinder 11 is used to drive the liquid collecting hopper 9 to expand or contract.

[0025] A cylinder fixing plate is welded to one end of the support 6 , and the bearing seat 13 is mounted on the cylinder fixing plate via a mounting bolt connection pair 14 .

[0026] The positioning clamp 16 is mounted on the gyration radius adjustment beam 15 and the liquid collecting hopper height adjustment vertical beam 17 by means of bolts. The specific position of the liquid collecting hopper 9 can be adjusted by the positioning clamp 16 .

[0027] The liquid collecting hopper bracket 8 is welded to the gyration radius adjustment beam 15 , and the liquid collecting hopper 9 is installed on the liquid collecting hopper bracket 8 through the quick-release bolts 7 .

[0028] The gyration radius adjustment beam 15 and the liquid collecting hopper height adjustment vertical beam 17 are both provided with a plurality of positioning installation holes to eliminate the interference between the liquid collecting hopper and the vertical pipe opening or the influence of the liquid collecting effect caused by the liquid collecting hopper being too far away from the vertical pipe opening during installation.

[0029] Working principle: A swing arm type pneumatic liquid receiving hopper device for top liquid loading and unloading, such as Figure 1 As shown, the device is controlled by an air control box assembly 3. The air control box assembly 3 has a control valve group 1 controlled by an electric signal, which controls the rotation of the rotating shaft 12 of the liquid collecting bucket and whether the single-position pneumatic valve 10 below the liquid collecting bucket is opened to discharge liquid. The air pipeline 4 is specially designed according to the specific arm product structure, striving to avoid interference with the movement process of the equipment. The support 6 is installed on the outer arm side of the horizontal rotary joint of the outer arm with the mounting bolt 5, and this side keeps synchronization with the horizontal rotation of the outer arm. The bearing seat 13 and the 180-degree swing cylinder 11 are installed on the support. The rotating shaft 12 passes through the swing cylinder 11 and the bearing seat (13) and is rigidly connected to the liquid collecting bucket height adjustment vertical beam 17. The positioning clamp 16 drives the slewing radius adjustment beam 15 to rotate horizontally to a maximum angle of 180 degrees. When the outer arm pitches up and down, it avoids the vertical pipe. When the vertical pipe needs to be connected to liquid, the liquid collecting bucket bracket 8 and the liquid collecting bucket 9 are rotated below the vertical pipe mouth to achieve liquid connection.

[0030] In order to ensure the accurate liquid receiving position, the device is equipped with multiple adjustment devices, which can accurately adjust the liquid collecting hopper to the appropriate position and lock it.

[0031] A single-position pneumatic valve 10 is installed under the liquid collecting hopper 9. It is usually closed when the power is off or the gas is off. The residual liquid can be collected and stored under the vertical pipe 21. It can be controlled to rotate to a suitable discharge position, such as a waste liquid collection barrel or the tank mouth of the next tank truck. The control valve group 1 is connected to the control power wind, and the valve can be opened to discharge the residual liquid.

[0032] In order to make the whole process run smoothly and reliably, a speed control valve 2 is added to the air control system to make the control and operation process smooth.

[0033] When the pneumatic liquid receiving hopper device is in the folded and retracted state, all components are outside the upward and downward movement range of the outer arm and will not interfere with the outer arm or the vertical pipe.

[0034] When loading / unloading is completed, the vertical pipe is pulled out of the tank mouth of the tank truck until the outer arm reaches the set height or the outer arm elevation angle reaches the set value, the outer arm pitch rotation should be locked, and the pneumatic system drives the 180-degree swing cylinder 11 to work, so that the device extends outward from the retracted state until the liquid collecting hopper 9 moves to the bottom of the vertical pipe mouth to catch the residual liquid sliding down the wall of the vertical pipe.

[0035] A pneumatic single-position normally closed valve is installed below the liquid collecting hopper 9. When there is no ventilation, the valve is in a normally closed state, ensuring that the residual liquid remains closed even in the event of a power outage or gas failure. The liquid collecting hopper 9 is located below the drop tube 21 and rotates with the drop tube 21 as the outer arm is in the upward locked state to maintain liquid collection.

[0036] It can be set that when the vertical pipe reaches a certain position above the special collector funnel or barrel, the solenoid valve is controlled to ventilate the pneumatic single-position valve below the liquid collecting hopper 9, and the valve is opened to achieve the effect of centralized collection of residual liquid.

[0037] In order to eliminate the problem that the horizontal swing range of the liquid collecting hopper 9 may exceed or fail to reach the vertical pipe mouth during installation, thereby affecting the use effect of the device, the device is set to have an adjustable rotation angle: the swing angle of the swing cylinder is adjustable, and the swing angle range of the cylinder can be adjusted by adjusting the two limit screws on the swing cylinder;

[0038] The different mounting holes of the vertical beam 17 can be used to adjust the height of the liquid collecting hopper for 90-degree rotation and positioning;

[0039] In order to eliminate the interference between the collecting hopper 9 and the vertical pipe mouth or the excessive distance from the vertical pipe mouth during installation, which affects the liquid receiving effect and the use effect of the device, the device is set to be adjustable in height and extension length: by selecting different positioning mounting holes on the vertical beam 17 for adjusting the height of the collecting hopper, different heights of the collecting hopper can be set, and by selecting different positioning mounting holes on the horizontal beam 15 for adjusting the rotation radius, different swing radii of the collecting hopper can be set.

[0040] In order to prevent the influence of failures such as malfunction of the discharge valve of the liquid collecting hopper 9 and damage to the liquid collecting hopper 9, the liquid collecting hopper 9 is designed to be installed with easily replaceable hook nails. It is firmly installed when in use and easy to disassemble and assemble during maintenance.

[0041] The above embodiments merely represent implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
