Description

Technical Field

[0001] The utility model belongs to the technical field of crane pipes, and in particular relates to a crane pipe with an explosion-proof mechanism. Background Art

[0002] In many industries such as petrochemicals, oil storage and transportation, and chemicals, crane pipes are one of the core equipment for liquid material loading and unloading operations. They undertake the important task of safely and efficiently transferring liquid materials (such as crude oil, refined oil, etc.) between storage tanks and transportation vehicles (such as tank trucks, tank trucks) or ships.

[0003] Currently, when a crane is used to load and unload liquids and there is a certain height difference between the storage tank and the transport vehicle, gravity can be used to achieve the flow of liquid. For example, when some gas stations unload oil into underground storage tanks, if the position of the tank truck is higher than the entrance of the underground storage tank, after injecting oil into the crane and opening the valve on the crane, the oil will flow from the tank truck through the crane into the underground storage tank under the action of gravity. However, after the loading and unloading operation of the traditional crane is completed, when the crane is pulled out of the transport vehicle or storage tank, a certain amount of oil will remain in the pipeline. This residual oil will drip along the pipeline to the ground in the loading and unloading operation area, which will also cause waste of oil and increase the operating costs of the enterprise. Utility Model Content

[0004] The purpose of the utility model is to provide a crane pipe with an explosion-proof mechanism to solve the problems raised in the above background technology.

By collecting the dripping return oil, the loss of oil is greatly reduced.

[0017] (2) The pressure relief shell, sealing block, spring and other structures in the explosion-proof assembly work together.

[0022] 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.

[0023] The utility model provides Figure 1-3 A crane pipe with an explosion-proof mechanism is shown, comprising:

[0024] A vertical pole 1, with a joint 2 connected to the surface of the vertical pole 1, one end of the joint 2 being connected to a connecting pipe 3, and the surface of the connecting pipe 3 being connected to the vertical pole 1 through a bracket, one end of the connecting pipe 3 being rotatably connected to a first rotary joint 4, and the other end of the first rotary joint 4 being rotatably connected to a straight pipe 5, and the other end of the straight pipe 5 being rotatably connected to a drop pipe 7 through a second rotary joint 6, one side of the drop pipe 7 being provided with a collecting assembly for collecting return oil dripping in the pipeline, and a collecting bucket 9 being driven to move by a first electric cylinder 8 of the collecting assembly so that the collecting bucket 9 moves to the bottom of the drop pipe 7 to collect the dripping return oil;

[0025] An explosion-proof component is provided on the surface of the straight pipe 5 and is used to relieve the pressure in the pipeline.

[0026] The collecting assembly includes a connecting plate 11 and a motor 12. The connecting plate 11 is connected to the surface of the vertical pipe 7 and the motor 12 is arranged on the surface of the connecting plate 11. The bottom of the connecting plate 11 is rotatably connected to a rotating box 13 through a bearing.

[0027] The output shaft of the motor 12 rotates through the connecting plate 11 and is connected to the rotating box 13 . The first electric cylinder 8 is disposed in the rotating box 13 , and the piston rod of the first electric cylinder 8 moves through the rotating box 13 and is connected to the collecting hopper 9 .

[0028] The collecting hopper 9 is provided with a collecting tank 23 and an oil drain pipe 10 is connected to the bottom of the collecting tank 23. After the return oil flows into the collecting tank 23, the collected return oil can be guided to a designated recovery container through the oil drain pipe 10.

[0029] The explosion-proof component includes a pressure relief shell 14 and a sealing block 15. The pressure relief shell 14 is connected to the straight pipe 5. A fixed plate 16 is provided in the pressure relief shell 14. The sealing block 15 is provided at the bottom of the fixed plate 16. Slide rods 17 are provided on both sides of the top of the sealing block 15. The other end of the slide rod 17 movably passes through the fixed plate 16. A spring 18 is sleeved on the surface of the slide rod 17. The two ends of the spring 18 are respectively connected to the fixed plate 16 and the sealing block 15. When the pressure is large, the medium pressure in the straight pipe 5 overcomes the force of the spring 18 to push the sealing block 15 to move upward. The slide rod 17 slides in the fixed plate 16 to play a guiding role. The sealing block 15 rises to open the pressure relief port 19, and part of the medium pressure is discharged out of the straight pipe 5 through the pressure relief port 19.

[0030] Pressure relief ports 19 are provided on both sides of the pressure relief shell 14. A sealing gasket 20 is connected to the surface of the sealing block 15. The sealing gasket 20 is made of rubber and can strengthen the sealing of the pressure relief port 19. A pressure gauge 24 is provided on the surface of the pressure relief shell 14. The pressure gauge 24 can monitor the pressure in the pipeline in real time.

[0031] A rotating block 21 is connected to the surface of the straight pipe 5. A second cylinder 22 is provided on the surface of the straight pipe 5, and the piston rod of the second cylinder 22 is rotatably connected to the rotating block 21. The piston rod of the second cylinder 22 can pull or push the rotating block 21 to rotate, and when the rotating block 21 rotates, it drives the straight pipe 5 to rotate through the first rotating joint 4, so that the first rotating joint 4 and the second rotating joint 6 can ensure that the pipeline connection is smooth and can be flexibly rotated.

[0032] The crane pipe with an explosion-proof mechanism, when performing liquid loading and unloading operations, connects the joint 2 to the external oil supply pipeline, allowing the oil to enter the straight pipe 5 through the connecting pipe 3, and the oil flows through the first rotary joint 4, the straight pipe 5, the second rotary joint 6 in sequence during transportation to reach the vertical pipe 7, and finally flows into the target storage tank or transport vehicle. If there is a height difference, gravity flow can be used for loading and unloading, and the liquid flows naturally under the action of gravity. In this process, the piston rod of the second cylinder 22 can pull or push the rotating block 21 to rotate, and when the rotating block 21 rotates, it drives the straight pipe 5 to rotate through the first rotary joint 4, so that the first rotary joint 4 and the second rotary joint 6 can ensure that the pipeline connection is smooth and can be flexibly rotated to adapt to different loading and unloading positions and angle requirements;

[0033] After the oil transportation and loading and unloading operations are completed, some liquid will remain in the vertical pipe 7 to form return oil. At this time, the motor 12 in the collection assembly is started, and the output shaft of the motor 12 rotates to drive the rotating box 13 connected to it to rotate. Since the first electric cylinder 8 is installed in the rotating box 13 and the piston rod is connected to the collecting bucket 9, the rotating box 13 rotates to move the collecting bucket 9 to a suitable position at the bottom of the vertical pipe 7 to prepare for collecting return oil. When the collecting bucket 9 is in place, the first electric cylinder 8 is started, and the piston rod of the first electric cylinder 8 pulls the collecting bucket 9 upward, so that the collecting bucket 9 is close to the outlet of the vertical pipe 7 to collect the return oil dripping from the vertical pipe 7. A collection tank 23 is provided in the collecting bucket 9. After the return oil flows into the collection tank 23, the return oil is guided to the designated recovery container through the oil drain pipe 10, completing the return oil collection process to prevent the return oil from leaking to the ground.

[0034] During the oil loading and unloading process, the pressure gauge 24 of the explosion-proof component on the surface of the straight pipe 5 monitors the pressure in the pipeline in real time. When the pressure in the pipeline is normal, the sealing block 15 fits tightly against the inner wall of the pressure relief shell 14 to seal the pressure relief port 19 to ensure pipeline sealing. When the liquid is transported quickly and pressure is generated in the closed pipeline and the pressure is relatively high, the medium pressure in the straight pipe 5 overcomes the force of the spring 18 to push the sealing block 15 upward, and the slide bar 17 slides in the fixed plate 16 to play a guiding role. The sealing block 15 rises to open the pressure relief port 19, and part of the medium pressure is discharged from the straight pipe 5 through the pressure relief port 19 to achieve pressure relief. When the pressure drops to a safe range, the spring 18 force causes the sealing block 15 to fall back and close the pressure relief port 19, restoring the normal operating state of the pipeline, and effectively preventing the pipeline from bursting due to high pressure. Dangers such as pipe bursts.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
