[0001] This invention relates to the field of vortex flow meters, and more specifically to a vortex flow meter that is easy to assemble and disassemble. Background Technology

[0002] Vortex flow meters, a type of velocity flow measurement instrument based on the Karman vortex street principle, have been widely used in industrial fields such as petroleum, chemical, power, metallurgy, and water treatment due to their advantages such as wide measurement range, high accuracy, no moving parts, and low maintenance costs. They are used to continuously monitor and measure the volumetric or mass flow rates of various fluids such as gases, liquids, and steam, and are key equipment for fluid transport system control, energy consumption statistics, and process optimization in industrial production processes.

The transmission gear is rotatably installed in the second support platform through a third connecting shaft, and the push block is provided with a groove adapted to slide and connect the docking block.

[0008] As a further embodiment of the present invention, the disassembly and assembly limiting mechanism further includes a second motor for driving the transmission gear to rotate and adjust, a first worm gear is fixedly connected to the third connecting shaft, a first worm is meshed on the first worm gear, the first worm is fixedly connected to the output shaft of the second motor, and the second motor is fixedly installed inside the second support platform.

[0009] As a further embodiment of the present invention, the disassembly and assembly limiting mechanism further includes a first motor for driving the drive wheel to rotate assistedly. The drive wheel is rotatably mounted on the first support platform via a first connecting shaft. The first connecting shaft is synchronously connected to a second connecting shaft via a first synchronous belt. The second connecting shaft is fixedly connected to the output shaft of the first motor. The first motor is fixedly installed inside the first support platform.

[0010] As a further embodiment of the present invention, an electromagnet for assisting in positioning the mounting bolt is installed on the inner side of the placement hole, and the mounting bolt is made of ferromagnetic metal.

[0011] As a further embodiment of the present invention, the support adjustment mechanism further includes a first gear and a fourth gear for driving the first gear plate and the second gear plate to move up and down in a lifting connection. The first gear and the fourth gear are arranged to rotate in opposite directions. The first gear is meshed with the first gear plate, and the fourth gear is meshed with the second gear plate. The first gear is rotatably connected to the inside of the second support platform through a fourth connecting shaft, and the fourth gear is rotatably connected to the inside of the second support platform through a sixth connecting shaft.

This is suitable for installation scenarios in narrow pipe spaces. Furthermore, the base plate controlled by both mechanisms can be placed on the ground for stable support, thus optimizing the installation and docking process and improving disassembly and assembly efficiency and safety.

[0016] The designed disassembly and assembly limiting mechanism not only achieves centering and rotation control of the vortex flowmeter body, but also automatically connects the mounting bolts, avoiding deviations caused by manual handling. This synchronous movement and pre-tightening guidance installation method further shortens the installation time of the mounting bolts. Thus, in some hazardous and toxic environments, operators do not need to hold the mounting bolts at close range for alignment, thereby further reducing operational risks, significantly reducing reliance on manual labor, facilitating rapid disassembly and assembly of the vortex flowmeter body, and achieving high disassembly and assembly efficiency, making it convenient for installation and use.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] See Figures 1 to 11 A vortex flow meter that is easy to assemble and disassemble includes a vortex flow meter body 1, a flange 2 on the vortex flow meter body 1, a plurality of flange holes 3 on the flange 2, a first support platform 4 for support at the bottom of the vortex flow meter body 1, a second support platform 5 fixedly connected below the first support platform 4, and a base plate 27 movably installed below the second support platform 5. It also includes: The support adjustment mechanism is installed at the connection between the second support platform 5 and the base plate 27. It is used to adjust the height and position of the vortex flowmeter body 1. The support adjustment mechanism includes a first toothed plate 30 and a second toothed plate 42 for lifting and moving control. The first toothed plate 30 and the second toothed plate 42 are both limited and slidably connected to the inside of the second support platform 5. One end of the first toothed plate 30 and the second toothed plate 42 is fixedly installed with a moving wheel 28 for moving.

[0033] Furthermore, the support adjustment mechanism also includes a first gear 31 and a fourth gear 38 for driving the first toothed plate 30 and the second toothed plate 42 to move up and down. The first gear 31 and the fourth gear 38 are arranged in opposite directions. The first gear 31 is meshed with the first toothed plate 30, and the fourth gear 38 is meshed with the second toothed plate 42. The first gear 31 is rotatably connected to the inside of the second support platform 5 through the fourth connecting shaft 32, and the fourth gear 38 is rotatably connected to the inside of the second support platform 5 through the sixth connecting shaft 37.

[0034] Furthermore, the support adjustment mechanism also includes a third gear 34 for driving the first gear 31 and the fourth gear 38 to rotate synchronously. The third gear 34 is rotatably connected to the inside of the second support platform 5 through the fifth connecting shaft 35, and the third gear 34 is meshed with the second gear 33. The fifth connecting shaft 35 is synchronously connected to the sixth connecting shaft 37 through the second synchronous belt 36.

[0035] Furthermore, the support adjustment mechanism also includes a third motor 41 for driving the sixth connecting shaft 37 to rotate. A second worm gear 39 is fixedly connected to the sixth connecting shaft 37, and a second worm 40 is meshed with the second worm gear 39. The second worm 40 is fixedly connected to the output shaft of the third motor 41, and the third motor 41 is fixedly installed inside the second support platform 5.

[0036] Furthermore, the support adjustment mechanism also includes a lifting electric push rod 26 for lifting assistance. The lifting electric push rod 26 is fixedly installed on the base plate 27, and the piston rod of the lifting electric push rod 26 is fixedly connected to the second support platform 5. The base plate 27 is provided with a clearance groove 29 for the clearance moving wheel 28.

[0037] Preferably, when installing and docking the vortex flow meter body 1, the vortex flow meter body 1 is placed on the first support platform 4. Under the lifting control of the lifting electric push rod 26, the moving wheels 28 on the first toothed plate 30 and the second toothed plate 42 fall to the ground for support, thereby making the base plate 27 away from the ground. At this time, it is convenient to move the placed vortex flow meter body 1 to the required docking and installation position.

[0038] When the vortex flowmeter body 1 is moved to the required installation position, in order to improve the stability of the subsequent installation of the vortex flowmeter body 1, the output shaft of the third motor 41 drives the second worm gear 40 to rotate. Under the meshing connection between the second worm gear 40 and the second worm wheel 39, the sixth connecting shaft 37 is driven to rotate. Under the synchronous driving action of the second synchronous belt 36, the third gear 34 on the fifth connecting shaft 35 is driven to rotate. Under the meshing connection between the third gear 34 and the second gear 33, the first gear 31 on the fourth connecting shaft 32 is driven to rotate. Thus, the fourth gear 38 and the first gear 31 rotate synchronously and in opposite directions, so that the synchronous lifting control of the first toothed plate 30 and the second toothed plate 42 can be well realized. At this time, the first toothed plate 30 and the second toothed plate 42 can easily lift the moving wheel 28 to the top, so that the base plate 27 can be placed on the ground for stable support. The lifting electric push rod 26 is adjusted accordingly to further improve the installation stability of the vortex flowmeter body 1.

[0039] By setting up the overall height adjustment method of the electric lifting rod 26 and the first toothed plate 30 and the second toothed plate 42, the support height of the vortex flowmeter body 1 can be well adjusted. If the height adjustment is limited to the electric lifting rod 26, when the base plate 27 is placed on the ground for support, the electric lifting rod 26 can only raise the height of the second support platform 5, so the height of the vortex flowmeter body 1 cannot be well controlled.

[0040] When the vortex flow meter body 1 needs to be moved to the installation site, the moving wheels 28 can be lowered and contact the ground through the coordinated control of the lifting electric push rod 26 and the third motor 41. At this time, the base plate 27 is lifted off the ground, and the operator only needs a small pushing force to move the vortex flow meter body 1. This is suitable for installation scenarios in narrow pipes. In addition, the base plate 27 controlled by the two can be placed on the ground for stable support, thereby optimizing the installation and docking process and improving the efficiency and safety of disassembly and assembly.

[0041] like Figures 1-10 As shown, this embodiment, based on the above embodiment, also includes a disassembly and assembly limiting mechanism, which is installed at the connection between the first support platform 4 and the second support platform 5. It is used to limit the adjustment and disassembly and assembly of the vortex flowmeter body 1. The disassembly and assembly limiting mechanism includes a drive wheel 6 for assisting the rotation of the vortex flowmeter body 1 and a push block 11 for driving the vortex flowmeter body 1 to be centered and assisting in disassembly and assembly. The push block 11 is slidably connected to the second support platform 5. Several adjusting electric push rods 12 are fixedly connected to the push block 11. The piston rod of the adjusting electric push rod 12 is connected to a docking block 13. Several placement holes 14 for placing mounting bolts 16 are opened on the docking block 13.

[0042] Furthermore, the disassembly and assembly limiting mechanism also includes a second slider 18 and a transmission gear 20 for driving the push block 11 to perform linear movement control. The push block 11 is slidably connected to the second support platform 5 through the first slider 17 and the second slider 18. The inner side of the second slider 18 is provided with a plurality of teeth 19 that mesh with the transmission gear 20. The transmission gear 20 is rotatably installed in the second support platform 5 through the third connecting shaft 21, and the push block 11 is provided with a groove 25 adapted to slide and connect to the docking block 13.

[0043] Furthermore, the disassembly and assembly limiting mechanism also includes a second motor 24 for driving the transmission gear 20 to rotate and adjust, a first worm gear 22 is fixedly connected to the third connecting shaft 21, a first worm 23 is meshed on the first worm gear 22, the first worm 23 is fixedly connected to the output shaft of the second motor 24, and the second motor 24 is fixedly installed inside the second support platform 5.

[0044] Furthermore, the disassembly and assembly limiting mechanism also includes a first motor 10 for driving the drive wheel 6 to rotate assistedly. The drive wheel 6 is rotatably mounted on the first support platform 4 via a first connecting shaft 7. The first connecting shaft 7 is synchronously connected to a second connecting shaft 9 via a first synchronous belt 8. The second connecting shaft 9 is fixedly connected to the output shaft of the first motor 10. The first motor 10 is fixedly installed inside the first support platform 4.

[0045] Furthermore, an electromagnet 15 for assisting in positioning the mounting bolt 16 is installed on the inner side of the placement hole 14, and the mounting bolt 16 is made of ferromagnetic metal.

[0046] Preferably, in this embodiment, to further improve the installation accuracy and stability of the vortex flowmeter body 1, the output shaft of the second motor 24 drives the first worm gear 23 to rotate. Under the meshing connection between the first worm gear 23 and the first worm wheel 22, the transmission gear 20 on the third connecting shaft 21 is driven to rotate. Under the meshing connection between the transmission gear 20 and the teeth 19 on the second slider 18, the push block 11 is driven to move closer to each other, thereby facilitating the centering and clamping of the vortex flowmeter body 1 placed on the first support platform 4, so that the center of the vortex flowmeter body 1 is located at the center position of the first support platform 4.

[0047] Furthermore, in order to better align the flange 2 on the vortex flowmeter body 1 with the flange hole of the pipeline, the output shaft of the first motor 10 drives the second connecting shaft 9 to rotate, and under the synchronous drive of the first synchronous belt 8, drives the drive wheel 6 on the first connecting shaft 7 to rotate. This facilitates the rotational adjustment of the central part of the vortex flowmeter body 1 at a certain angle, so that the side flange 2 on the vortex flowmeter body 1 can better align with the flange of the pipeline.

[0048] Once the vortex flowmeter body 1 is centered and positioned, several mounting bolts 16 for installation and connection are placed in the placement holes 14 on the docking block 13. The electromagnets 15 in the placement holes 14 are magnetically attracted and fixed. At this time, the output shaft of the second motor 24 rotates in the reverse direction to drive the push block 11 to move the mounting bolts 16 on the docking block 13 towards the side pipe flange for better installation. Correspondingly, the vortex flowmeter body 1 can be disassembled and assembled by simply driving in the reverse direction, making it convenient to use.

[0049] The designed disassembly and assembly limiting mechanism not only achieves centering and rotation control of the vortex flowmeter body 1, but also automatically connects the mounting bolts 16, avoiding deviations caused by manual handling. This synchronous movement and pre-tightening guidance installation method further shortens the installation time of the mounting bolts 16. Thus, in some hazardous and toxic environments, operators do not need to hold the mounting bolts 16 at close range for alignment, thereby further reducing operational risks, significantly reducing reliance on manual labor, facilitating rapid disassembly and assembly of the vortex flowmeter body 1, with high disassembly and assembly efficiency, and convenient installation and use.

[0050] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
