The first direction is a left-right direction.
[0028] With the above arrangement, the flow meter 3000 can be fixed between the first pipe 1000 and the second pipe 2000 through the first clamping assembly 500 and the second clamping assembly 600, which greatly improves the connection efficiency compared with bolt connection, and through the movable arrangement of the second clamping piece 320, the second mounting assembly 300 and the intermediate mounting assembly 400 on the base 100, the distance between the first pipe 1000 and the second pipe 2000 can be adjusted to adapt to flow meters 3000 of different lengths, reduce the adjustment difficulty, and effectively improve the detection efficiency of flow meters 3000 of various lengths.
[0029] In some embodiments, the first clamping assembly 500 and the second clamping assembly 600 are the same in structure.
[0030] Specifically, the first clamping assembly 500 comprises a first clamping seat, a first clamping driving piece, a first connecting rod and a first clamping rod, the first clamping seat is provided with a first clamping channel, the first pipe 1000 is arranged in the first clamping channel, the diameter of the first clamping channel is smaller than that of the first flange 1100, the first clamping seat is arranged on the base 100, the first clamping driving piece is arranged on the first clamping seat, one end of the first connecting rod is hinged to the first clamping seat, the first clamping rod is hinged to the other end of the first connecting rod, one end of the first clamping rod is hinged to the output end of the first clamping driving piece, and the first flange 1100 and the third flange 3100 can be clamped between the other end of the first clamping rod and the first clamping seat. Through the clamping mode, the connection of the flow meter 3000 and the first pipe 1000 can be quickly completed. The first clamping driving piece is a hydraulic cylinder.
[0031] The first connecting rod effectively avoids displacement of the contact end of the first clamping rod and the third flange 3100, avoids relative sliding between the first clamping rod and the third flange 3100, and reduces the risk of scratching the third flange 3100.
[0032] To achieve force balance between the first flange 1100 and the third flange 3100, in some embodiments, the first clamping assembly 500 includes a plurality of first clamping driving members and a plurality of first clamping rods, the plurality of first clamping driving members are arranged one-to-one with the plurality of first clamping rods, and are uniformly distributed on the outer periphery of the first pipeline 1000, and the plurality of first clamping driving members are synchronously actuated. The plurality of first clamping driving members are connected in parallel through the same hydraulic pipeline, thereby achieving pressure balance.
[0033] Regarding the structure of the second clamping assembly 600, in some embodiments, the second clamping assembly 600 includes a second clamping seat 610, a second clamping driving member 620, and a second clamping rod 630. The second clamping seat 610 has a second clamping channel, the second pipeline 2000 is arranged in the second clamping channel, the diameter of the second clamping channel is smaller than that of the second flange 2100, and the second clamping seat 610 is movably arranged on the base 100. The second clamping driving member 620 is arranged on the second clamping seat 610, the second clamping rod 630 is hingedly connected to the second clamping seat 610, one end of the second clamping rod 630 is hingedly connected to the output end of the second clamping driving member 620, and the second flange 2100 and the fourth flange 3200 can be clamped between the other end of the second clamping rod 630 and the second clamping seat 610. The above arrangement realizes rapid clamping of the second flange 2100 and the fourth flange 3200, and improves the fixing efficiency of the flowmeter 3000. The distance between the hinge connection point of the second clamping rod 630 and the second clamping seat 610 and the hinge connection point of the second clamping rod 630 and the second clamping driving member 620 is a first distance, the distance between the hinge connection point of the second clamping rod 630 and the second clamping seat 610 and the abutting point of the second clamping rod 630 and the fourth flange 3200 is a second distance, and the first distance is greater than the second distance, thereby realizing amplification of the output force of the second clamping driving member 620.
[0034] The second clamping seat 610 includes a second seat body 611 and a second connecting rod 612, one end of the second connecting rod 612 is hingedly connected to the second seat body 611, and the second clamping rod 630 is hingedly connected to the other end of the second connecting rod 612. The second connecting rod 612 is arranged, which effectively avoids displacement of the contact end of the second clamping rod 630 and the fourth flange 3200, avoids relative sliding between the second clamping rod 630 and the fourth flange 3200, and reduces the risk of scratching the fourth flange 3200.
[0035] The base 100 is provided with a sliding rail 110, and the second clamping seat 610 is slidably arranged on the sliding rail 110 through a sliding block 120. The sliding rail 110 is mounted on the base 100 through a base 130. The pressing block is mounted on the base 100 and presses the sliding rail 110. The base 130 and the base 100 are provided with a rib plate 140. The rib plate 140 is in the shape of a right-angled triangle, and the inclined surface forms an angle of 45° with the horizontal plane. In other embodiments, the second clamping seat 610 can be arranged on the base 100 by rolling through a roller.
[0036] To realize the stress balance between the second flange 2100 and the fourth flange 3200, in some embodiments, the second clamping assembly 600 includes a plurality of second clamping driving members 620 and a plurality of second clamping rods 630, the plurality of second clamping driving members 620 and the plurality of second clamping rods 630 are arranged one by one and uniformly distributed on the outer periphery of the second pipeline 2000, and the plurality of second clamping driving members 620 act synchronously. The force of each second clamping driving member 620 is parallel to the first direction. The second clamping driving member 620 is a hydraulic cylinder. The plurality of second clamping driving members 620 are connected in parallel through the same hydraulic pipeline, thereby realizing pressure balance. Exemplarily, the second clamping assembly 600 includes ten second clamping driving members 620.
[0037] In some embodiments, the second clamping assembly 600 further includes a first power member 640, which is arranged on the base 100 and has an output end connected with the second clamping seat 610. When the first power member 640 drives the second clamping seat 610 to approach the intermediate mounting assembly 400, the second mounting assembly 300 can be driven to approach the intermediate mounting assembly 400 through the second pipeline 2000. The above arrangement improves the automation degree of the fixing process of the flowmeter 3000, thereby further improving the fixing efficiency of the flowmeter 3000. At the same time, when the first power member 640 acts, the second pipeline 2000 is synchronously driven to move, and the second mounting assembly 300 is driven to move through the second pipeline 2000. The above linkage action, on the one hand, ensures that the second flange 2100 on the second pipeline 2000 and the second clamping seat 610 abut, and ensures the clamping reliability; on the other hand, avoids driving the second mounting assembly 300 alone, and improves the consistency of movement.
[0038] Further, the second mounting assembly 300 comprises a second support base 310, a second clamping member 320 and a second power member 330. The second support base 310 is movably arranged on the base 100 along a first direction. The second clamping member 320 is arranged on the second support base 310 and is used for clamping the second pipe 2000. The second power member 330 is arranged on the base 100 and the output end of the second power member 330 is connected with the second support base 310. When the second power member 330 drives the second support base 310 to move away from the intermediate mounting assembly 400, the second pipe 2000 can drive the second clamping assembly 600 to move away from the intermediate mounting assembly 400. The above arrangement improves the disassembly efficiency of the flow meter 3000. In addition, under the driving of the second power member 330, the second pipe 2000 and the second clamping base 610 can be synchronously moved to avoid interference.
[0039] The second clamping member 320 comprises two second clamping jaws which are perpendicular to the axis of the second pipe 2000 and can be clamped on the outer periphery of the second pipe 2000. When the two second clamping jaws are clamped, they can wrap two-thirds of the outer diameter of the second pipe 2000.
[0040] The first mounting assembly 200 comprises a first support base and a first clamping member. The first support base is fixed on the base 100. The first clamping member is arranged on the first support base and is used for clamping the first pipe 1000.
[0041] The first clamping member comprises two first clamping jaws which are perpendicular to the axis of the first pipe 1000 and can be clamped on the outer periphery of the first pipe 1000. When the two first clamping jaws are clamped, they can wrap two-thirds of the outer diameter of the first pipe 1000.
[0042] Different models of flow meters 3000 have different diameters. To achieve quick docking, in some embodiments, the intermediate mounting assembly 400 comprises an intermediate base 410, a lifting base 420 and a lifting driving member 430. The intermediate base 410 is movably arranged on the base 100 along a first direction. The lifting base 420 is movably arranged on the intermediate base 410 along a second direction. The lifting driving member 430 is arranged on the intermediate base 410 and the output end of the lifting driving member 430 is in transmission connection with the lifting base 420. The second direction is perpendicular to the first direction. The above arrangement realizes the lifting of the lifting base 420. When the diameter of the flow meter 3000 is large, the height of the lifting base 420 is appropriately lowered to make the axis of the flow meter 3000 and the first pipe 1000 collinear. The intermediate base 410 is in sliding cooperation with the slide rail 110 through the sliding block 120. The intermediate mounting assembly 400 comprises a third power member 460. The third power member 460 is arranged on the base 100 and the output end of the third power member 460 is in transmission connection with the intermediate base 410.
[0043] Further, the lifting seat 420 comprises a lifting body 421 and a transverse moving member 422, the lifting body 421 is movably arranged in the intermediate seat 410 along a second direction, the transverse moving member 422 is adjustably arranged in the lifting body 421 along a third direction, the transverse moving member 422 is used for carrying the flowmeter 3000, and the third direction is perpendicular to the second direction and the first direction. The above arrangement can adjust the position of the flowmeter 3000 along the third direction, so that the axis of the flowmeter 3000 and the axis of the first pipeline 1000 are collinear. The lifting body 421 has a mounting groove, and the side wall of the mounting groove is provided with an anti-skid plate for preventing the transverse moving member 422 from slipping. The second direction is the up-down direction, and the third direction is the front-back direction.
[0044] In order to adapt to flowmeters 3000 of different diameters, in some embodiments, the transverse moving member 422 is provided with a V-shaped groove, and the extension direction of the V-shaped groove is parallel to the axis of the flowmeter 3000. In order to ensure that the flowmeter 3000 and the transverse moving member 422 remain relatively stable, in some embodiments, the intermediate mounting assembly 400 further comprises two push members 440, the two push members 440 are arranged on the transverse moving member 422 and located between the third flange 3100 and the fourth flange 3200, one output end of one push member 440 abuts against the third flange 3100, and the output end of the other push member 440 abuts against the fourth flange 3200. The push member 440 is a pneumatic cylinder, a hydraulic cylinder or an electric push rod.
[0045] In order to facilitate installation, the transverse moving member 422 is provided with a positioning hole, the lifting body 421 is provided with a plurality of positioning grooves arranged along the third direction, and a positioning pin 450 passes through the positioning hole and is selectively inserted into the positioning grooves. The transverse moving member 422 is provided with a lifting ring, and the lifting ring is used for lifting the entire transverse moving member 422 and the flowmeter 3000.
[0046] In some embodiments, the flowmeter docking tool further comprises a sealing assembly 700, the sealing assembly 700 comprises a sealing support 710, a gasket 720 and a mechanical hand 730, the sealing support 710 is arranged on the base 100 and can carry the gasket 720, and the mechanical hand 730 can pick up the gasket 720 and place the gasket 720 between the first flange 1100 and the third flange 3100 or between the second flange 2100 and the third flange 3100. The above arrangement realizes the sealed connection between the first flange 1100 and the third flange 3100, and the sealed connection between the second flange 2100 and the fourth flange 3200. In this embodiment, during the docking process of the flowmeter 3000, the first power member 640 and the second power member 330 need to act, so that there is a gap between the second flange 2100 and the third flange 3100 when the gasket 720 is installed.
[0047] The front end of the manipulator 730 has an upper clamp jaw 731 and a lower clamp jaw 732, and the upper clamp jaw 731 and the lower clamp jaw 732 can approach or move away from each other to clamp or release the gasket 720. The gasket 720 includes an inner ring and an outer ring, and the outer ring is arranged on the outer periphery of the inner ring. The inner ring is provided with a graphite gasket on both sides. The thickness of the upper clamp jaw 731 and the lower clamp jaw 732 is less than the sum of the thicknesses of the inner ring and the two graphite gaskets. The thickness of the outer ring is 4-5 mm.
