Description
Technical Field
The invention relates to the technical field of measurement, in particular to an auxiliary device for liquid drainage of a U-shaped mass flowmeter.
Background
The flowmeter is widely applied to various aspects such as industry, agriculture, national defense, scientific research, production and life of people and the like, and is an important flow metering appliance. The flow meters can be classified into velocity type flow meters, volumetric flow meters, differential pressure type flow meters, mass flow meters, and the like according to the measurement principle. The mass flowmeter can directly measure the mass flow of the liquid medium passing through the flowmeter, does not need to measure pressure and temperature, and has less measuring links, thereby having wide application. A U-tube is typically connected below the mass flow meter. The U-shaped tube is designed according to the mass flow measurement principle, the electromagnetic mechanism enables the U-shaped tube to vibrate, and the mass flow of the U-shaped tube can be known by measuring the phase difference of the U-shaped tube distortion (when no flow exists and when the flow exists). The U-shaped mass flowmeter is easily affected by factors such as environment and the like to generate metering deviation in use, so that the calibration or calibration needs to be carried out by a third-party verification or calibration mechanism within a specified period, and the reliability and the accuracy of the indicating value of the flowmeter are ensured. The U-shaped mass flowmeter is verified or calibrated by introducing test liquid into the flowmeter, and after verification or calibration is finished, the liquid in the flowmeter needs to be emptied. Because U type mass flow meter flowing back needs to overturn the flowmeter, when the flowmeter pipe diameter is great, flowmeter overall structure, weight are all very big, generally with the overhead traveling crane hoist installation/dismantlement, bare-handed upset is difficult to, the upset of forcing arouses the flowmeter easily to rock, drops even, causes serious influence for safety in production. The U type mass flow meter flowing back need place the flowmeter on the ground and perk flowmeter afterbody again and carry out the flowing back, and is consuming time longer, reduces flowmeter examination or calibration efficiency. Most of liquid discharged by the flowmeter directly flows on the ground, so that the working environment is influenced, and even the ground slip is caused to cause potential safety hazards.

The U-shaped mass flow meter 2 is constituted by a U-shaped pipe 21 and a flow meter body 22. The U-shaped pipe 21 is formed by smoothly connecting two vertical pipes and a horizontal pipe. The standpipe of the U-tube 21 is connected to a flowmeter body 22. The horizontal pipe of the U-pipe 21 is parallel to the flowmeter body 22. The U-shaped pipe 21 is connected with a lifting lug 3. The lifting lug 3 is close to the flowmeter body 22. The return channel 4 is typically an elongated channel located in the laboratory floor. The overhead traveling crane is located the laboratory top. The overhead traveling crane can walk over a laboratory. The lifting lug 3 is connected with the crown block through a lifting rope.
The frame body 1 may have various structures. The frame body 1 is exemplified as a rectangular parallelepiped structure in this embodiment. The upper part of the frame body 1 is connected with a bracket 11. The bracket 11 is positioned at the center of the frame body 1 and is higher than the upper surface of the frame body 1. The bracket 11 is formed by connecting three planes to form a U shape. The carriage 11 is provided with rollers 111 on three sides. The roller 111 is a cylinder. The central axis of the roller 111 is parallel to the surface of the bracket 11. The sides of the cylinder of the roller 111 project above the surface of the carrier 11. The U-shaped tube 21 is placed on the bracket 11, and the outer surface of the horizontal tube of the U-shaped tube 21 is attached to the side surface of the roller 111 connected with the three surfaces of the bracket 11.

The central axis of the vertical screw rod 12 is parallel to the central axis of the frame body 1. The frame body 1 is provided with a horizontal screw rod 16. The central axis of the horizontal screw rod 16 is vertical to the central axis space of the vertical screw rod 12. The vertical screw 12 is engaged with the horizontal screw 16. The vertical screw rod 12 can drive the bracket 11 to lift by rotating the horizontal screw rod 16.
The lower end of the frame body 1 is connected with a universal wheel 14. The universal wheels 14 are four and are positioned at four corners of the lower surface of the frame body 1, which are close to the frame body 1. The side of the universal wheel 14 is connected with a fixed column 15 which can be lifted. The fixed column 15 is a screw. In this embodiment, there are four fixing posts 15. A fixed column 15 is arranged on the side of one universal wheel 14. The fixing column 15 is in threaded connection with the lower surface of the frame body 1. The lower end of the fixed column 15 is connected with a truncated cone-shaped fixed disk. The fixed column 15 is rotated, and the fixed disc can be lifted.
The side surface of the frame body 1 is rotatably connected with a wing piece 13. The fins 13 are plate-shaped, and the geometry can be various, and this embodiment is exemplified by the structure that the fins 13 are right-angled triangles. One right-angle surface of the wing piece 13 is parallel to the ground, and the other right-angle surface is provided with a connecting rod. The connecting rod includes a connecting rod vertical part 131 and a connecting rod horizontal part 132. The connecting rod vertical part 131 is connected with the connecting rod horizontal part 132, and the connecting rod is in a cross shape.
The side of the frame body 1 is fixedly connected with a connecting barrel 19. The connecting barrels 19 are in groups of eight and two. The connecting barrels 19 of each group are separated from each other by a certain distance, and the central axes of the two connecting barrels 19 are overlapped. Each group of connecting barrels 19 is positioned on the side surface of the frame body 1 and close to the side edge of the frame body 1.

The wing 13 is unfolded, the horizontal part 132 of the connecting rod falls into the rotating hole 193, the wing 13 is locked, and the right-angle surface of the wing 13 parallel to the ground is tightly attached to the ground. The fixed column 15 is rotated, and a fixed disc connected with the lower end of the fixed column 15 is tightly attached to the ground. The frame body 1 is fixed on the side of the reflux groove 4. The crown block is connected with the lifting lug 3 through a lifting rope. The crown block lifts the U-shaped mass flow meter 2 away from the experiment table. The crown block moves to place the horizontal tubes of the U-shaped tubes 21 on the bracket 11. The horizontal screw rod 16 is rotated, the vertical wire 12 drives the bracket 11 to rise, meanwhile, the crane sling is loosened, the flowmeter body 22 descends, and the flowmeter body 22 is in a lower state, and the horizontal pipe of the U-shaped pipe 21 is in an upper state. The two legs of the U-shaped tube 21 open into the return tank 4, and the U-shaped tube 21 drains the test solution in the tube into the return tank 4 (see fig. 1). When the test liquid in the U-shaped pipe 21 is drained, the horizontal screw rod 16 is rotated, the vertical wire 12 drives the bracket 11 to descend, the crane sling is tightened, and the U-shaped mass flow meter 2 is lifted to leave the bracket 11. The wing pieces 13 rotate, the horizontal portion 132 of the connecting rod is separated from the rotating holes 193 and ascends along the lifting groove 192, and the right-angle surface of the wing pieces 13 parallel to the ground is separated from the ground and is attached to the side of the frame body 1 (as shown in fig. 5). The fixed column 15 is rotated, and the fixed disc connected with the lower end of the fixed column 15 leaves the ground. The frame body 1 is moved out of the return tank 4 by the pull rod 17.
