Description

Technical Field

[0001] The present invention relates to the technical field related to loading crane pipes, and in particular to an intelligent fully automatic positioning crane pipe. Background Art

[0002] Loading crane pipe, also known as fluid loading and unloading arm, is a kind of retractable and movable pipe. It is mainly used for liquid loading and unloading operations in petroleum and chemical terminals and production processes, such as loading and unloading of petroleum products such as crude oil, gasoline, diesel, lubricating oil, and loading and unloading of concentrated sulfuric acid, liquefied natural gas, liquefied petroleum gas, molten sulfur, asphalt, carbon disulfide and other chemical products. The crane pipe is connected with rigid pipes and elbows through a rotating joint to realize the transmission of liquid media between trains, tank cars and trestle storage and transportation pipelines, replacing the old hose connection.

[0003] The main pipelines of existing crane pipes are mainly made of forged steel or aluminum alloy. Compared with hoses, they have reliable sealing performance and are durable. Crane pipes often need to contact highly corrosive or highly adhesive fluid materials during operation. When there is a blockage inside, it is not easy to find the internal blockage through external observation. During the unloading process, when the vehicle's pressure pump is started, the inside of the crane pipe will continue to be pressurized. If there is a blockage inside the crane pipe at this time, the continuous high-pressure state will easily damage the sealing structure of the crane pipe connection part, and severely cause the crane pipe to break, posing a safety hazard. At the same time, the pressure cannot be effectively relieved before the interface is removed, so there are disadvantages in use. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide an intelligent fully automatic alignment crane pipe to solve the problem mentioned in the above background that when the existing crane pipe is blocked inside, the internal blockage state is not easy to find through external observation. During the unloading process, when the vehicle's booster pump is started, the inside of the crane pipe will continue to be pressurized. If the inside of the crane pipe is blocked at this time, the continuous high-pressure state is likely to damage the sealing structure of the crane pipe connection part, and in severe cases it is easy to cause the crane pipe to be damaged, posing a safety hazard. At the same time, the pressure cannot be effectively relieved before the interface is removed, so there are disadvantages in use.

[0017] Furthermore, one end of each of the bypass pipes is connected to the interior of an adapter, and the other end of each of the bypass pipes is connected to the interior of a pressure relief device base.

[0018] Furthermore, each of the pressure relief device bases is provided with a pressure groove inside, and the inner wall of each pressure groove is provided with a group of bypass grooves, and each group of bypass grooves is provided with a plurality of bypass grooves distributed at equal angles with respect to the axis of the pressure groove;

[0025] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0026] 1. In the present invention, a first linear module, a second linear module, a third linear module, a fourth linear module and a movable frame are provided, and a clamp which can adjust the angle by controlling a motor is installed on the movable frame, and the end of the clamp is a semi-open annular clamp structure with good elasticity, which can temporarily clamp and fix the third armored explosion-proof bent pipe or the fourth armored explosion-proof bent pipe of different specifications, and the movable frame can rely on the mutual cooperation of the first linear module, the second linear module, the third linear module and the fourth linear module to drive the clamp and the third armored explosion-proof bent pipe or the fourth armored explosion-proof bent pipe connected thereto to move in all directions, so that the operator can quickly adjust the position of the gas phase quick connector or the liquid phase quick connector, and quickly connect the vehicle or reset it, which saves time and effort and improves work efficiency.

[0027] 2. In the present invention, a joint for connecting the first pressure relief hose or the second pressure relief hose is provided on the third armored explosion-proof elbow and the fourth armored explosion-proof elbow. The material and size of the first pressure relief hose or the second pressure relief hose can be flexibly selected according to the composition of the fluid to be transported. During the unloading process, the internal pressure of the first pressure relief hose or the second pressure relief hose is consistent with the internal pressure of the third armored explosion-proof elbow or the fourth armored explosion-proof elbow. When a blockage occurs at any position inside the pipeline system, the internal pressure of the hose will increase, thereby causing the pressure applied inside the pressure tank to begin to increase. As the pressure exceeds the threshold, the rubber plug will be pushed away from the side. The through groove drives the movable rod to flip inward, and in the process of the movable rod rotating, the top of the movable rod will gradually squeeze the reset piston outward, and the cone-like structure at the lower end of the reset piston is wrapped by a group of snap blocks. In the process of squeezing the reset piston, the spring sheet at the rear end of the snap block will be squeezed. When the movable rod rotates to the maximum angle, the reset piston is pushed to completely disengage from the snap block. At this time, the rubber plug is completely out of the bypass groove and loses its restraining force. It will not be in a closed state again due to the reduction of internal pressure in the pipeline. The normally open state ensures that the internal pressure of the pipeline can be continuously released. After the pressure is discharged, the reset can be completed by pressing the reset piston again, thereby improving safety in use.

[0028] 3. In the present invention, a sealing plug, a return spring and a limit disk are provided. The sealing plug is provided at the junction of the transfer tube and the adapter. The adapter is in the shape of a flying disc. Due to the shape limitation of the sealing plug, it can only move toward the inside of the transfer tube, and the sealing plug fits the inner wall contour of the transfer tube. Under normal transportation conditions, the sealing plug can effectively withstand the internal pressure of the transfer tube to prevent the fluid from flowing back into the adapter. Under the pressure relief state, due to the low elastic coefficient of the return spring itself, when the fluid enters the interior of the adapter, it will pass through the limit disk and easily push the sealing plug to move into the transfer tube. At this time, the transfer tube is connected to the interior of the adapter, and when the pressure disappears, the return spring can drive the sealing plug to quickly complete the reset.

[0051] Please refer to Figures 1 to 4 As shown, in this embodiment, the first linear module 2 and the second linear module 3 form a sliding structure, and the second linear module 3 and the third linear module 4 form a sliding structure, and the third linear module 4 and the fourth linear module 5 form a sliding structure. The fourth linear module 5 and the movable frame 6 form a lifting structure, and a control motor 7 is installed at the bottom of the movable frame 6, and the output shaft of the movable frame 6 is transmission connected to the clamp 8.

[0052] More specifically, the first linear module 2, the second linear module 3, the third linear module 4 and the fourth linear module 5 cooperate with each other to drive the movable frame 6 and the clamp 8 installed at the bottom thereof to move in all directions.

[0053] As a further illustration of this embodiment, the bottom of the clamp 8 is a semi-open clamp structure, which is convenient for temporarily clamping and fixing the third armored explosion-proof bent pipe 16 or the fourth armored explosion-proof bent pipe 18.

[0054] Please refer to Figures 7 to 10 As shown, in the present embodiment, each of the adapters 23 is connected to the interior of an adapter tube 22, and a sealing plug 24 is provided at the connection between each adapter 23 and the adapter tube 22; a limit plate 26 is installed on each of the sealing plugs 24, and a return spring 25 is wrapped around the outer side of each limit plate 26, and the limit plate 26 and the return spring 25 are both arranged inside the adapter 23; the top end of the limit plate 26 is a grid structure, and the limit plate 26, the sealing plug 24 and the return spring 25 form a telescopic structure.

[0055] Specifically, the sealing plug 24 can only slide in one direction toward the inside of the transfer tube 22 . When the sealing plug 24 moves, the limiting plate 26 is driven to move synchronously, and the correspondingly connected return spring 25 is compressed.

[0056] As a further illustration of this embodiment, the grid-structured limiting disk 26 ensures that the fluid can quickly enter the adapter 23 .

[0057] Please refer to Figures 1 to 6As shown, in this embodiment, one end of each bypass pipe 27 is connected to the interior of an adapter 23 , and the other end of each bypass pipe 27 is connected to the interior of a pressure relief device base 29 .

[0058] More specifically, the bypass pipe 27 is used to connect the pressure relief device base 29 and the adapter 23 .

[0059] As a further description of this embodiment, the bypass pipe 27 is a right-angle elbow structure.

[0060] Please refer to Figures 9 to 12 As shown, in this embodiment, each of the pressure relief device bases 29 is provided with a pressure groove 30 inside, and the inner wall of each pressure groove 30 is provided with a group of bypass grooves 33, and each group of bypass grooves 33 is provided with a plurality of bypass grooves 33 distributed at equal angles about the axis of the pressure groove 30; each of the pressure grooves 30 is connected to a bypass joint 31, and one of the bypass joints 31 is connected to the first pressure relief hose 20, and the other bypass joint 31 is connected to the second pressure relief hose 21; each of the pressure relief device bases 29 is installed with a pressure gauge 32.

[0061] More specifically, the pressure groove 30 is annular in structure. When the pressure relief device base 29 is connected to the pressure relief device housing 34 , the pressure groove 30 is in a relatively closed state and is only connected to the interior of the pressure relief device base 29 through the bypass groove 33 .

[0062] As a further explanation of this embodiment, the pressure value inside the pressure tank 30 can be observed through the pressure gauge 32 .

[0063] Please refer to Figures 9 to 14 As shown, in this embodiment, a group of movable rods 35 are installed inside each of the pressure relief device housings 34, and each group of movable rods 35 is provided with a number of movable rods 35 at equal angles with respect to the axis of the pressure relief device housing 34; each of the movable rods 35 is connected to the pressure relief device housing 34 by rotation, and a rubber plug 36 is installed at the end of each movable rod 35; each of the rubber plugs 36 is connected to a bypass groove 33.

[0064] More specifically, the internal pressure of the pressure tank 30 is transmitted to the same set of rubber plugs 36 .

[0065] As a further explanation of this embodiment, when the pressure exceeds the threshold, the rubber plug 36 will be pushed inward to rotate synchronously with the movable rod 35 connected thereto. When the rubber plug 36 is separated from the bypass groove 33 , the pressure groove 30 is connected to the interior of the pressure relief device base 29 through the bypass groove 33 .

[0066] Please refer to Figures 9 and 10As shown, in the present embodiment, each of the pressure relief device housings 34 is provided with a group of limit grooves 37 inside, and each group of limit grooves 37 is provided with a number of limit grooves 37 at equal angles with respect to the axis of the pressure relief device housing 34, and each limit groove 37 is provided with a snap-fit ​​block 38; a spring sheet 39 is installed between each snap-fit ​​block 38 and the limit groove 37, and the snap-fit ​​block 38 is connected to the limit groove 37 in a sliding manner, and the spring sheet 39 and the snap-fit ​​block 38 form a sliding structure.

[0067] Specifically, the same set of engaging blocks 38 cooperate with each other to wrap the spherical part of the lower end of the reset piston 41, thereby fixing the reset piston 41. At this time, the bottom of the reset piston 41 is tightly against the top of the movable rod 35, thereby giving the movable rod 35 a restraining force.

[0068] As a further illustration of this embodiment, the axis of the pressure relief device housing 34 , the axis of the pressure tank 30 , and the axis of the pressure relief device housing 34 are all on the same straight line.

[0069] Please refer to Figures 9 to 14 As shown, in this embodiment, a reset piston 41 is provided inside each of the pressure relief device housings 34 , and the lower portion of each reset piston 41 is engaged with a set of engaging blocks 38 , and the end of each reset piston 41 is connected to a pressure relief device top cover 40 .

[0070] More specifically, the lower end of the reset piston 41 is a pyramidal structure.

[0071] As a further explanation of this embodiment, after the reset piston 41 is squeezed out of the wrapping of the engaging block 38 , it is convenient to quickly reset by pressing the end of the reset piston 41 .

[0072] The working principle of the present invention is as follows: when in use, the external power supply is turned on, and the first linear module 2, the second linear module 3, the third linear module 4 and the fourth linear module 5 are started as required, and after the movable frame 6 and the clamp 8 installed at the bottom thereof are driven to move to the designated position, the clamp 8 and the third armored explosion-proof bent pipe 16 or the fourth armored explosion-proof bent pipe 18 to be used are engaged and connected with the clamp 8, and the first linear module 2, the second linear module 3, the third linear module 4 and the fourth linear module 5 are continued to be started as required, and the gas phase quick connector 17 or the liquid phase quick connector 19 is driven by the clamp 8 to quickly approach the designated vehicle, and the gas phase quick connector 17 or the liquid phase quick connector 19 is connected to the pipeline of the vehicle through the moving gas phase quick connector 17 or the liquid phase quick connector 19;

[0073] During the unloading process, if the inside of the pipeline is blocked, the internal pressure of the first pressure relief hose 20 or the second pressure relief hose 21 will increase. At this time, the pressure is continuously applied to the rubber plug 36 through the pressure groove 30. As the pressure increases, the rubber plug 36 is gradually squeezed inward. When the pressure exceeds the threshold, the rubber plug 36 and the connected movable rod 35 are completely pushed inward to flip inward. During the flipping of the movable rod 35, the top end of the movable rod 35 will squeeze the reset piston 41 outward, and the reset piston 41 will squeeze outward during the outward movement. By pressing the engaging block 38 and the spring sheet 39, the cone-like structure at the lower part of the reset piston 41 will completely disengage from the engaging block 38 after a very short stroke. At this time, the rubber plug 36 is completely separated from the bypass groove 33, and the fluid entering the pressure groove 30 passes through the bypass groove 33 and is injected into the pressure relief device housing 34, and then continues to pass through the limit plate 26 through the bypass pipe 27 and enters the adapter 23. After the pressure of the fluid pushes the sealing plug 24 to move to the inside of the adapter tube 22, the fluid inside the adapter 23 is continuously injected into the adapter tube 22 to complete the pressure relief.

[0074] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
