[0002] The crane pipe is a device that is connected in series with a rotating joint that is flexible and has good sealing performance and a pipeline. It is used to transport liquid media. The media that can be transported include diesel, lubricating oil, gasoline, etc. It can also transport liquefied natural gas, liquefied petroleum gas, molten sulfur, asphalt, carbon disulfide and other chemical products. For dangerous chemicals, the use of the crane pipe improves the safety of loading and unloading operations.
[0003] When loading crane pipes, in order to prevent oil and gas leakage, various forms of sealing devices are usually installed at the lower end of the vertical pipe, such as external cylinder compression, inflated reverse tank mouth, installation of PTFE cone caps or cone caps with elastic rubber seals that fit tightly with the tank mouth. However, the liquid at the tank mouth flowing through the crane pipe will cause vibration, and the height of the vehicle will sink after the liquid is loaded, the height of the tank mouth will become lower, the tank mouth and the cone barrel cannot fit tightly or the compression force is uneven, the sealing effect is poor, and the gap changes greatly, which can easily cause oil and gas leakage when filling the crane pipe. In addition, after the crane pipe is loaded, corrosive residual liquid will drip from the inner arm of the vertical pipe, causing environmental pollution and waste of resources, and endangering personnel health.

A three-dimensional compensating sealing device with a residual liquid collecting function is provided to solve the problem that during the loading process of the crane pipe, the tank mouth and the crane pipe are not tightly fitted, and the vertical pipe drips residual liquid, which damages the environment and endangers the health of personnel.
[0005] To solve the above problems, the technical solution adopted by the present utility model is to provide a three-dimensional compensation sealing device with a residual liquid collection function, which is arranged on a vertical pipe and includes a sealing mechanism and a residual liquid collection mechanism. The sealing mechanism includes an upper connecting plate slidably connected to the vertical pipe. A bellows is fixedly connected to the center of the bottom of the upper connecting plate. The bottom of the bellows is fixedly connected to a lower connecting plate. An connecting rod is arranged between the upper connecting plate and the lower connecting plate. One end of the connecting rod is slidably connected to the upper connecting plate through a rod seat, and the other end is fixedly connected to a universal bearing. The universal bearing is fixedly connected to the top of the lower connecting plate. A spring is sleeved outside the connecting rod. A guiding pipe is fixedly connected to the bottom of the lower connecting plate. The other end of the guiding pipe is fixedly connected to a conical cap.

At the same time, the counterweight of the residual liquid collection mechanism and the cylinder cooperate to realize automatic liquid receiving.
[0007] As a further description of the above technical solution, there is at least one pair of the connecting rods.
[0008] By adopting the above technical solution, the connecting rods can make the up and down movement of the lower connecting plate and the lower connecting plate more stable, enable the conical cap to rotate flexibly at multiple angles, compensate for movement errors in the horizontal and vertical directions, and seal the contact surface between the tank opening and the conical cap in three-dimensional angles.

[0010] By adopting the above technical solution, the disassembly of the residual liquid collection mechanism can be realized. The clamping part of the U-shaped clamp is sleeved on the vertical pipe, the pressing plate is sleeved on the other end of the clamping part, and the L-shaped plate passes through the clamping part and is fixed with a nut to complete the installation of the residual liquid collection mechanism.
[0011] As a further description of the above technical solution, the other end of the cylinder air pipe is connected to a solenoid valve. The input end of the solenoid valve is electrically connected to a PLC controller.
[0012] By adopting the above technical solution, the PLC controller can control the power on and off of the solenoid valve, thereby controlling the up and down movement of the cylinder piston rod.

[0014] By adopting the above technical solution, before filling, the cylinder drives the lifting rod to move upward. After the liquid receiving bucket contacts the vertical pipe, it rotates downward under the force of the vertical pipe, and the lifting rod continues to rise. The liquid receiving bucket moves upward along the outer wall of the crane pipe until the liquid receiving bucket is completely moved out of the bottom of the vertical pipe to avoid affecting the filling of the vertical pipe.
[0015] As a further description of the above technical solution, the counterweight block and the liquid receiving bucket maintain balance in the absence of external force.
[0016] By adopting the above technical solution, after filling is completed, the cylinder drives the lifting rod to descend, and the liquid receiving plate can automatically become a horizontal state under the action of the counterweight block and the liquid receiving bucket to achieve liquid receiving.

During filling, the cylinder drives the lifting rod and the liquid receiving bucket to rise, so that the liquid receiving bucket moves upward along the outer wall of the vertical tube to avoid affecting the filling of the vertical tube. After the filling is completed, the cylinder piston rod extends out, and the bottom of the lifting rod descends to the bottom of the vertical tube. The liquid receiving plate remains horizontal under the action of the counterweight block and the liquid receiving bucket to achieve liquid receiving. BRIEF DESCRIPTION OF THE DRAWINGS

Example
[0037] like Figure 1-5As shown in the figure, a three-dimensional compensation sealing device with a residual liquid collection function is arranged on the vertical pipe 100, including a sealing mechanism 1. The sealing mechanism 1 includes an upper connecting plate 11 slidably connected to the vertical pipe 100. A corrugated pipe 12 is fixedly connected to the center of the bottom of the upper connecting plate 11. The bottom of the corrugated pipe 12 is fixedly connected to a lower connecting plate 13. There is at least one pair of connecting rods 14 between the upper connecting plate 11 and the lower connecting plate 13. One end of each connecting rod 14 is slidably connected to the upper connecting plate 11 through a rod seat 15, and the other end is fixedly connected to a universal bearing 16. The universal bearing 16 is fixedly connected to the top of the lower connecting plate 13. A spring 17 is sleeved outside the connecting rod 14. A guide pipe 18 is fixedly connected to the bottom of the lower connecting plate 13. The other end of the guide pipe 18 is fixedly connected to a conical cap 19, and the outer diameter of the conical cap 19 gradually increases from bottom to top;
[0038] As Figure 1 shown, the sealing mechanism 1 can be detachably connected to the vertical pipe through a flange 10;
[0039] As Figure 1-5 shown, it further includes a residual liquid collection mechanism 2. The residual liquid collection mechanism 2 includes a cylinder 21 and a guide rod 22. The cylinder 21 is installed on the vertical pipe 100 through a cylinder fixing bracket 23. The other end of the piston rod of the cylinder 21 is fixedly connected to a lifting rod 24. The other end of the lifting rod 24 is rotatably connected to a liquid receiving plate 25. The lifting rod 24 and the liquid receiving plate 25 are in an "丄" shape. One end of the liquid receiving plate 25 is fixedly connected to a liquid receiving hopper 26, and the other end is connected to a counterweight 27. The counterweight 27 and the liquid receiving hopper 26 are balanced without external force. The shortest distance of the opening surface of the liquid receiving hopper 26 is at least greater than the diameter of the vertical pipe 100. The stroke length of the cylinder 21 is at least greater than the sum of the distance between the bottom end of the vertical pipe 100 and the bottom of the liquid receiving hopper 26 and half of the longest distance of the opening surface of the liquid receiving hopper 26 after the device is installed.
[0040] As Figure 6 shown, the cylinder fixing bracket 23 includes a U-shaped clamp 231 detachably connected to the vertical pipe 100. The U-shaped clamp 231 includes a hoop part 2311 and a pressing plate 2313 cooperating with the hoop part 2311 through a nut 2312. The other side of the pressing plate 2313 is detachably connected to an L-shaped plate 232. The cylinder 21 and the guide rod 22 are fixedly connected to the L-shaped plate 232.
[0041] In this embodiment, the other end of the air pipe of the cylinder 21 is connected to a solenoid valve, and the input end of the solenoid valve is electrically connected to a PLC controller.
[0042] This device can be installed on vertical pipes with different diameters and be adaptively improved. Therefore, the vertical pipe is equivalent to a fitting of this device, rather than a fixed part of this device.
[0043] Working principle: When using the device, first install the residual liquid collection mechanism 2, put the hoop 2311 of the U-shaped clamp 231 on the vertical pipe 100, put the pressing plate 2313 on the other end of the hoop 2311, and pass the L-shaped plate 232 through the hoop 2311 and fix it with the nut 2312 to complete the installation of the residual liquid collection mechanism 2. Then install the sealing mechanism 2, put the sealing mechanism 2 on the outside of the vertical pipe 100, so that the bottom of the conical cap 19 is at a certain distance from the bottom of the vertical pipe 100, and use bolts to tighten the flange 10 to complete the installation. When the crane pipe is filling, the vertical pipe 100 moves to the top of the tank mouth and the vertical pipe 100 descends. When it descends to a certain height, the PLC controller controls the solenoid valve to ventilate, the cylinder 21 contracts, and the piston rod of the cylinder 21 drives the lifting rod 24 to rise. The liquid receiving bucket 26 contacts the vertical pipe 100 and rotates downward under the action of the vertical pipe 100. One end of the counterweight block 27 rotates upward. At the same time, the liquid remaining in the liquid receiving bucket 26 from the last filling will pour into the tank mouth. The lifting rod 24 continues to rise, and the liquid receiving bucket 26 moves upward along the outer wall of the vertical pipe 100, and will not affect the filling below the vertical pipe 100. After the liquid receiving hopper 26 leaves the mouth of the vertical pipe 100, the vertical pipe 100 continues to descend, and the tank mouth generates an upward thrust on the conical cap 19, which is transmitted to the guide tube 18, the lower connecting plate 13 and the connecting rod 14 in sequence. The bellows 12 and the spring 17 outside the connecting rod 14 are compressed, and the upper end of the connecting rod 14 extends out from the rod seat 15 of the upper connecting plate 11. The connecting rod 14 can press the conical cap 19 through the universal bearing 16 at the bottom, so that the conical cap 19 is in sealing contact with the tank mouth. At this time, filling work can be carried out, avoiding environmental pollution and casualties caused by oil and gas leakage.
[0044] After the filling work is completed, the vertical pipe moves upward, the compressed bellows 12 and spring 17 gradually rebound, the upper end of the connecting rod 14 gradually returns to the rod seat 15, the conical cap 19 is out of contact with the tank mouth, and the vertical pipe 100 continues to rise. When it rises to a certain height, the PLC controller controls the solenoid valve to ventilate, and the piston rod of the cylinder 21 extends downward, driving the lifting rod 24 to descend. The bottom of the lifting rod 24 moves to the bottom of the vertical pipe 100, and the vertical pipe 100 is no longer in contact with the liquid receiving bucket 26. Under the action of the counterweight block 27, the liquid receiving plate 25 can remain horizontal, and the liquid receiving bucket 26 can automatically receive the liquid. The residual liquid is poured into the next car during the next filling, avoiding waste of resources.
