[0020] See also Figure 1 , Figure 2 , Figure 3The utility model provides a technical solution: a movable flow meter calibration integrated device, comprising a flow meter lifting device 1 and a box 2. The flow meter lifting device 1 is arranged on the top of the box 2. The flow meter lifting device 1 comprises a slide rail 11, a sliding box 12, a first slider 13, a first clamping plate 14, a bearing seat 15, a threaded rod 16, a second slider 17, a second clamping plate 18 and an adjusting member 19.

[0021] The bottom surface of the sliding box 12 is slidably connected to the sliding rail 11. The first slider 13 and the second slider 17 are slidably connected to the inner side wall of the sliding box 12. The first clamping plate 14 is provided on the first slider 13. The second clamping plate 18 is provided on the second slider 17. The threaded rod 16 is provided in the sliding box 12. The bearing seat 15 is provided at the connection between the sliding box 12 and the threaded rod 16. The outer side of the threaded rod 16 is provided with a bidirectional thread. The threaded rod 16 is threadedly connected to the first slider 13 and the second slider 17. One end of the threaded rod 16 passes through the side wall of the sliding box 12 and is connected to the adjusting member 19.

[0022] Furthermore, at least two sliding boxes 12 are provided on the top of the slide rail 11 .

[0023] In the flowmeter lifting device 1, the sliding box 12 is adjusted to a distance that adapts to the length of the flowmeter through the slide rail 11. At this time, the flowmeter is placed on the first clamping plate 14 and the second clamping plate 18 to complete the preliminary calibration and positioning. The length is adjusted by sliding the distance between the two sliding boxes 12 to meet the needs of lifting various flowmeters. At the same time, the threaded rod 16 is driven by the adjusting member 19 to make the first slider 13 and the second slider 17 slide left and right, thereby changing the clamping width, thereby achieving the effect of accurately adjusting the height of the lifted flowmeter. The first slider 13 and the second slider 17 in the sliding box 12 are approached or moved away at the same time, and the bearing seats 15 at both ends of the sliding box 12 can ensure the concentric movement of the first slider 13 and the second slider 17.

[0024] Further, the sliding box 12 includes a side plate 121, a slider guide rail 122 and a baffle 123. The baffles 123 are respectively provided on both end surfaces of the side plate 121. The slider guide rail 122 is provided on the inner side surface of the side plate 121 close to the first slider 13 and the second slider 17. The first slider 13 and the second slider 17 are both slidably connected to the slider guide rail 122. A bearing seat 15 is provided on the side wall of the baffle 123. The threaded rod 16 is connected to the baffle 123 through the bearing seat 15.

[0025] Furthermore, a water collecting tank 3, a water pump 5 and a distribution box 6 are provided in the box body 2. The water collecting tank 3 is located directly below the flow meter lifting device 1. The distribution box 6 is electrically connected to the water pump 5. The input end of the water pump 5 is connected to the bottom of the side of the water collecting tank 3 through a pipeline. The output end of the water pump 5 is connected to the circulating water tank through a pipeline.

[0026] A water tank is provided under the lifting mechanism, which can timely collect the waste liquid generated during the installation and disassembly of the flow meter. The water tank has its own liquid level gauge and is equipped with a water pump to discharge the collected waste liquid to a designated location. The flow meter will cause a lot of internal liquid to leak out during detection. The water collecting tank 3 is used to collect the outflowing liquid, and the liquid in the water collecting tank 3 is pumped out by the water pump 5 and pumped into the external circulating water pool. The external circulating water pool then provides liquid supply to the flow meter to be tested. This setting can reduce the waste of water resources.

[0027] Furthermore, a liquid level meter 4 is provided on the outer side of the water collecting tank 3 .

[0028] Furthermore, a differential pressure transmitter 7 is provided on the top of the box 2. The differential pressure transmitter 7 is connected to the front and rear pipes of the flow meter to be tested through a hose, and performs pressure monitoring on the flow meter to be tested during the calibration process.

[0029] Furthermore, a plurality of universal wheels are provided at the bottom of the box body 2.

[0030] Working principle:

[0031] In the flowmeter lifting device 1, the sliding box 12 is adjusted to a distance that adapts to the length of the flowmeter through the slide rail 11. At this time, the flowmeter is placed on the first clamping plate 14 and the second clamping plate 18 to complete the preliminary calibration and positioning. The length is adjusted by sliding the distance between the two sliding boxes 12 to meet the needs of lifting various flowmeters. At the same time, the threaded rod 16 is driven by the adjusting member 19 to make the first slider 13 and the second slider 17 slide left and right, thereby changing the clamping width, thereby achieving the effect of accurately adjusting the height of the lifted flowmeter. The first slider 13 and the second slider 17 in the sliding box 12 are approached or moved away at the same time, and the bearing seats 15 at both ends of the sliding box 12 can ensure the concentric movement of the first slider 13 and the second slider 17.

[0032] During the flow meter inspection, a lot of internal liquid will leak out. The water collecting tank 3 is used to collect the outflowing liquid, and the liquid in the water collecting tank 3 is pumped out by the water pump 5 and pumped into the external circulating water pool. The external circulating water pool then provides liquid supply to the flow meter to be inspected. The differential pressure transmitter 7 is connected to the front and rear pipes of the flow meter to be inspected through a hose, and the pressure of the flow meter to be inspected is monitored during the inspection process.
