Description

Technical Field

[0001] The utility model relates to the technical field of mass flow meters, in particular to a mass flow meter that is easy to disassemble and assemble. Background Art

[0002] The mass flow meter directly measures the mass flow of the medium passing through the flow meter, and can also measure the density of the medium and indirectly measure the temperature of the medium. It has flexible configuration, powerful functions, high performance-price ratio, and is a new generation of flow meter. Mass flow meters can be divided into two categories according to different measurement methods: one is direct type, that is, directly outputting mass flow; the other is indirect or derived type, such as the combination of ultrasonic flowmeter and density meter, and then multiplying their outputs to obtain mass flow. Among them, direct mass flow meters such as dual impeller type and indirect mass flow meters such as Coriolis mass flow meters are large in size and heavy in weight when measuring large pipe diameters and large flows, and need to be lifted to the installation location with the help of cranes, forklifts and other tools.

[0003] At present, when installing the mass flow meter, the mass flow meter needs to be fixed, which makes it inconvenient to disassemble and repair it. In addition, during long-term use, it may be affected by external activities and become loose, thus affecting the mass flow meter.

[0024] Among them, the top of the upper clamping plate 9 is fixedly connected with a positioning block 12, the top of the movable bracket 5 is fixedly connected with a fixing nut 501, the internal thread of the fixing nut 501 is connected with a ball screw 13, the upper end of the ball screw 13 is fixedly connected with a rocker 14, and the ball screw 13 and the positioning block 12 are movably connected through a bearing.

[0025] Among them, a number of springs 15 are fixedly welded to the lower end of the lower clamping plate 11, and the inner sides of the upper clamping plate 9 and the lower clamping plate 11 are provided with equidistant anti-slip teeth. By setting the anti-slip teeth, the flow meter can be prevented from sliding or shifting when placed, and the flow meter can be prevented from shifting to affect the fixation of the clamp, providing a guiding tube bundle for the clamp.

[0026] Among them, a number of fixing rods 19 are fixedly welded on the outer side of the base plate 1, and the inside of the fixing rods 19 is slidably connected with the support legs 20. Corresponding positioning holes are opened on the surfaces of the fixing rods 19 and the support legs 20. A positioning pin 21 is set on one side of the fixing rod 19, and the positioning pin 21 is detachable. By setting the positioning pin 21, the upper and lower positions can be adjusted.

[0027] Among them, a support plate 16 is fixedly welded to the upper end of the base plate 1, a hydraulic rod 17 is fixedly connected to one side of the support plate 16, and the output end of the hydraulic rod 17 passes through the support plate 16 and is fixedly connected to an arc-shaped clamping plate 18.

After confirmation, the ball screw 13 is driven to rotate synchronously by turning the rocker 14, so that the height of the ball screw is continuously reduced, and the upper clamping plate 9 is clamped with the lower clamping plate 11, and the hydraulic rod 17 and the hydraulic rod 23 are started so that the arc clamping plate 18 at the output end and the arc guide plate 24 can be clamped to prevent their position from being offset during disassembly and assembly and affecting the fixation of the clamping, so as to play a better guiding role and finally achieve the purpose of stable clamping. Finally, screws are set on the upper slide bar 8 to clamp the upper slide bar 8 with the lower slide bar 10. Double clamping can improve the stability of fixation. When fixation is not required, the above process can be operated in the opposite direction to loosen the position of the upper clamping plate 9 to achieve the purpose of loosening the clamping.
