Description

Technical Field

[0001] This invention belongs to the field of flow meter installation technology, specifically a docking installation structure for a flow meter. Background Technology

[0002] A flow meter, also known as a flow meter, is an instrument used to measure the flow rate of fluids in pipelines (the volume of fluid passing through per unit time). It measures the instantaneous flow rate and cumulative volume of liquids, and can also quantitatively control liquids. It features high accuracy, long lifespan, and simple operation and maintenance. It is mainly used in industrial production processes, energy metering, environmental protection engineering, transportation, biotechnology, scientific experiments, marine meteorology, rivers and lakes, and other fields. Common flow meters include electromagnetic flow meters, rotor flow meters, ultrasonic flow meters, vortex flow meters, and mass flow meters. Flow meters are widely used in liquid transportation to detect the flow rate of media, ensuring that the flow rate is controlled within an appropriate range.

[0003] In the installation structure of flow meters, the basic requirements are sealed installation and convenient assembly. In the existing technology, the installation of flow meters requires multiple people to support them and then use various installation tools to connect the flanges at both ends of the flow meter with the flanges of the connecting pipes on both sides. Since multiple people are working at the same time, and the connecting pipes are usually long and large, it is difficult for workers to ensure precise alignment when manually lifting the connecting pipes and assembling them with the docking structure. This alignment installation process is time-consuming and labor-intensive. Summary of the Invention

A flow meter is installed on the top of the bend, and an upper pipe is provided on the top of the flow meter. A clamping mechanism is symmetrically arranged at the upper and lower ends of the straightening mechanism; The corrective mechanism includes: The lower housing has its outer wall fitted onto the outer wall of the support mechanism; The upper housing is rotatably connected to the top of the lower housing; A limiting component, wherein the limiting components are symmetrically arranged on the inner wall of the upper housing; An alignment component is disposed in the middle of the inner wall of the upper housing.

[0005] Furthermore, the support mechanism includes: The bracket has rollers symmetrically arranged at its bottom, and the outer wall of the rollers is rotatably connected to the inner wall of the bracket. A sleeve rod is symmetrically arranged on the top of the bracket, and the outer wall of the sleeve rod is sleeved with the inner wall of the straightening mechanism.

[0006] Furthermore, the straightening mechanism also includes: A cylinder is disposed on the back of the lower housing, and the top of the cylinder is rotatably connected to the outer wall of the lower housing. A pad, the outer wall of which is rotatably connected to the bottom of the cylinder; A rotating plate is symmetrically arranged on the outer wall of the lower housing, and the outer wall of the rotating plate is rotatably connected to the outer wall of the lower housing.

[0007] Furthermore, the straightening mechanism also includes: The second telescopic column is evenly distributed on the inner wall of the upper housing; A clamping block is disposed on the top of the second telescopic column, and the outer wall of the clamping block is in contact with the inner wall of the upper housing. An infrared receiver is disposed on the side of the clamp block near the alignment assembly.

[0008] Furthermore, the clamping mechanism includes: A retaining ring, the outer wall of which is rotatably connected to the outer wall of the straightening mechanism; The sleeve is evenly arranged on the outer wall of the retaining ring, and the inner wall of the sleeve is evenly provided with limit grooves. A connecting rod, the outer wall of which is sleeved with the inner wall of a retaining ring.

[0009] Furthermore, the clamping mechanism also includes: A rotating block, the bottom of which is rotatably connected to the top of a connecting rod, and the outer wall of the rotating block is provided with protrusions; A U-shaped rod is mounted on top of the rotating block; A pad is installed at the bottom of the connecting rod, and the outer wall of the pad contacts the inner wall of the retaining ring.

[0010] Furthermore, the limiting component includes: A fixing frame, wherein the fixing frame is symmetrically arranged on the inner wall of the upper housing; A guide rod is installed on the inner wall of the fixed frame, and air holes are provided at both ends of the guide rod; An inflatable ring is provided on the outer wall of the guide rod, and the inner wall of the inflatable ring is connected to the inner wall of the guide rod. A one-way hole is provided on the side of the guide rod near the inflatable ring.

[0011] Furthermore, the limiting component also includes: Two gas delivery pipes are symmetrically arranged and are located at both ends of the guide rod; An airbag is positioned at the end of the air supply pipe furthest from the guide rod.

[0012] Further, the alignment component includes: The first telescopic column is installed in the middle of the inner wall of the upper housing; An arc-shaped plate is installed on top of the first telescopic column.

[0013] Furthermore, the alignment component also includes: Infrared emitters are symmetrically arranged at the upper and lower ends of the arc-shaped plate; The clamping rods are evenly arranged on the inner wall of the arc-shaped plate, and the bottom of the clamping rods is rotatably connected to the inner wall of the arc-shaped plate.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting up a straightening mechanism, inserts a limiting component into the flange connecting the bend and the flow meter, keeping the bend stable and aligned with the bottom axis of the flow meter. Screws are then inserted into the flange for pre-fixation. Finally, the limiting component is pulled out, and all screws are tightened. This facilitates the installation of the flow meter by workers on the connecting pipes, ensuring alignment between the axes of the connecting pipes and the flow meter. This improves installation efficiency, reduces the number of workers required for installation, and avoids situations where large, round pipes are difficult to apply force to, thus improving construction safety.

[0015] 2. This invention uses a clamping mechanism to ensure that the axis of the upper pipe is aligned with the axis of the flow meter. Then, the worker manually rotates the U-shaped rod, causing it to bring the pad under the connecting rod closer to the pipe. After compression, rotating the U-shaped rod causes the rotating block to insert into the limiting groove inside the sleeve, causing the pad to be clamped onto the outer wall of the pipe. Together with the clamping block, the upper pipe is wrapped and clamped, keeping the pipe axis aligned. This assists the worker in installation and reduces the difficulty of manual alignment.

[0016] 3. By setting a limiting component, the present invention allows the guide rod to be inserted into the flange, indicating that the axis difference between the flow meter and the bend is small. It can also further limit the pipe, preventing the pipe from shifting after the clamping mechanism has fixed the pipe, thus increasing the displacement restriction on the pipe. After fine adjustments, the operation of installing the flow meter on the upper and lower pipes can be completed quickly, reducing the difficulty of manual alignment and adjustment.

[0017] 4. This invention, by setting an alignment component, aligns the axis of the flow meter with the axis of the arc plate, and also ensures that the axis of the arc plate corresponds to the arrangement position of the infrared transmitter. When the infrared transmitter and the infrared receiver are connected, it indicates that the axis of the pipe and the flow meter are consistent. This makes it easier for workers to quickly determine whether the axis is aligned, reducing the labor cost of manually aligning the pipe. It also allows for a more intuitive judgment of whether the pipe is aligned before tightening the screws, avoiding the need for secondary disassembly and delaying the work process.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-7 The present invention provides a technical solution: a docking and installation structure for a flow meter is described below.

[0022] include: Support mechanism 1, with a straightening mechanism 5 installed at the top of support mechanism 1; Bend 2 is located inside the straightening mechanism 5. A flow meter 3 is installed on the top of bend 2, and an upper pipe 4 is installed on the top of flow meter 3. The clamping mechanism 6 is symmetrically arranged at the upper and lower ends of the straightening mechanism 5; During operation, the upper pipe 4 and flow meter 3 are placed inside the straightening mechanism 5. Initially, the upper half of the straightening mechanism 5 is in a horizontal state. Then, the upper pipe 4 and the top of the flow meter 3 are installed. Then, the support mechanism 1 is pushed so that the bend 2 is locked in the lower half of the straightening mechanism 5 and fixed. After the upper pipe 4 and the bend 2 are fixed to both ends of the straightening mechanism 5 by the clamping mechanism, the straightening mechanism 5 is merged so that the bottom of the flow meter 3 is installed with the top of the bend 2.

[0023] Supporting mechanism 1 includes: The bracket 101 has rollers 103 symmetrically arranged at its bottom, and the outer wall of the rollers 103 is rotatably connected to the inner wall of the bracket 101. Sleeve rod 102 is symmetrically arranged on the top of bracket 101, and the outer wall of sleeve rod 102 is sleeved with the inner wall of straightening mechanism 5.

[0024] The five supporting agencies include: The lower housing 501 has its outer wall sleeved with the outer wall of the support mechanism 1; The upper housing 505 is rotatably connected to the top of the lower housing 501. Limiting component 506 is symmetrically arranged on the inner wall of the upper housing 505; Alignment component 507 is disposed in the middle of the inner wall of the upper housing 505.

[0025] The 5th reformatory also includes: Cylinder 502 is located on the back of the lower housing 501, and the top of cylinder 502 is rotatably connected to the outer wall of the lower housing 501. The outer wall of the pad 503 is rotatably connected to the bottom of the cylinder 502; Rotating plate 504 is symmetrically arranged on the outer wall of the lower housing 501, and the outer wall of rotating plate 504 is rotatably connected to the outer wall of the lower housing 501.

[0026] The 5th reformatory also includes: The second telescopic column 508 is evenly distributed on the inner wall of the upper housing 505; Clamping block 509 is located on top of the second telescopic column 508. The outer wall of clamping block 509 contacts the inner wall of the upper housing 505. Clamping block 509 is made of rubber with high hardness. Since the second telescopic column 508 is arranged with the axis of the alignment component 507 as the center, clamping block 509 can adjust pipes of different diameters on the same axis, so that pipes of different specifications can be in contact with clamping block 509 and fixed to keep the axis the same. Infrared receiver 510 is disposed on the side of clamp 509 near alignment assembly 507.

[0027] In use, first rotate the rotating plate 504 180 degrees downwards to separate the upper housing 505 from the lower housing 501, so that the upper housing 505 and the lower housing 501 are in a vertical state. Place the upper housing 505 horizontally, and then place the flow meter 3 and the upper tube 4 inside the upper tube 4. The alignment component 507 holds the flow meter 3 in place. The upper tube 4 is clamped by the clamping mechanism 6 on the outer wall of the upper housing 505, and the limit component 506 cooperates to keep the axis of the upper tube 4 and the flow meter 3 aligned by the alignment component 507. Then the upper tube 4 and the flow meter 3 are installed. After the upper pipe 4 and flow meter 3 are installed, the lower housing 501, in conjunction with the clamping mechanism 6, fixes the outer wall of the bend 2. Then, with the help of external force, the worker rotates the upper housing 505, along with the upper pipe 4 and flow meter 3, by 90 degrees, so that the rotating plate 504 rotates to contact the upper housing 505 and remains stationary. At this time, the upper housing 505 and the lower housing 501 keep the axes of the bend 2 and the upper pipe 4 aligned, and also ensure that the flow meter 3 is aligned with the top of the bend 2. Then, the limiting component 506 is inserted into the flange connecting the bend 2 and the flow meter 3 to keep the bend 2 stable and aligned with the bottom axis of the flow meter 3. Then, the screws are inserted into the flange for pre-fixing. Finally, the limiting component 506 is pulled out and all the screws are tightened, which makes it easier for the worker to install the flow meter 3 on the upper and lower connected pipes. This ensures that the axes of the upper and lower connected pipes and the flow meter 3 are aligned, improves the worker's installation efficiency, reduces the number of workers required for operation and installation, and avoids the situation where the pipe is large and round, making it difficult to apply force and requiring the worker to directly contact the pipe for adjustment, thus improving the safety of construction.

[0028] The clamping mechanism 6 includes: The outer wall of the retaining ring 601 is rotatably connected to the outer wall of the straightening mechanism 5. The sleeve 602 is evenly distributed on the outer wall of the retaining ring 601, and the inner wall of the sleeve 602 is evenly provided with limit grooves 603. The connecting rod 607 has its outer wall fitted into the inner wall of the retaining ring 601.

[0029] The clamping mechanism 6 also includes: Rotating block 605, the bottom of rotating block 605 is rotatably connected to the top of connecting rod 607, and the outer wall of rotating block 605 is provided with protrusion 606; U-shaped rod 604, which is mounted on top of rotating block 605; The pad 608 is installed at the bottom of the connecting rod 607. The outer wall of the pad 608 is in contact with the inner wall of the retaining ring 601. The pad 608 has a certain degree of elasticity.

[0030] Initially, rotating one end of the retaining ring 601 moves it away from the upper housing 505, opening it up. Then, the upper tube 4 is placed in the slot of the upper housing 505. The second telescopic column 508 moves the clamping block 509 closer to the outer wall of the upper tube 4. The retaining ring 601 rotates, clamping the upper tube 4 between it and the upper housing 505. The second telescopic column 508 moves the clamping block 509 until the infrared receiver 510 on the clamping block 509 communicates with the infrared transmitter 5073 on the alignment assembly 507, thus enabling... The axis of the upper pipe 4 is aligned with the axis of the flow meter 3. Then, the worker manually rotates the U-shaped rod 604, causing the U-shaped rod 604 to bring the pad 608 under the connecting rod 607 closer to the pipe and form a compression. Then, the worker rotates the U-shaped rod 604 to drive the rotating block 605 to insert into the limiting groove 603 inside the sleeve 602, so that the pad 608 is stuck on the outer wall of the pipe. Together with the clamping block 509, the upper pipe 4 is wrapped and clamped, keeping the pipe axis aligned. This assists the worker in installation and reduces the difficulty of manual adjustment and alignment.

[0031] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the limiting component 506 includes: Fixing bracket 5061 is symmetrically arranged on the inner wall of the upper housing 505; Guide rod 5062 is installed on the inner wall of the fixed frame 5061. The outer wall of guide rod 5062 is sleeved with the inner wall of fixed frame 5061. Guide rod 5062 can slide back and forth in fixed frame 5061. Air holes 5063 are opened at both ends of guide rod 5062. An inflation ring 5064 is disposed on the outer wall of the guide rod 5062. The inner wall of the inflation ring 5064 is connected to the inner wall of the guide rod 5062. A one-way hole 5065 is provided on the side of the guide rod 5062 near the inflation ring 5064. A groove is provided on the part of the guide rod 5062 near the inflation ring 5064, so that the inflation ring 5064 can retract into the groove when it is not inflated, and the outer diameter of the guide rod 5062 remains consistent.

[0032] Limiting component 506 also includes: There are two gas transmission pipes 5066 symmetrically arranged, and the gas transmission pipes 5066 are located at both ends of the guide rod 5062; Airbag 5067 is located at the end of air supply pipe 5066 away from guide rod 5062. Airbag 5067 is made of rubber and supplies air to inflation ring 5064 in one direction. Inflation ring 5064 can deflate on its own.

[0033] With the upper housing 505 in a horizontal position, place the flow meter 3 on the alignment assembly 507, place the upper pipe 4 on the end of the upper housing 505 away from the alignment assembly 507, so that the outer wall of the upper pipe 4 is fixed by the upper housing 505, and then insert the guide rod 5062 into the flange of the upper pipe 4 and the flow meter 3, and pass the upper air inlet pipe through the flange of the upper pipe 4 and the flow meter 3. After confirming the alignment of the upper pipe 4 with the axis of the flow meter 3 by using the alignment component 507, fix the upper pipe 4 with the flow meter 3 through the screw holes except for the guide rod 5062. Then rotate the upper housing 505 upward by 90 degrees to coincide with the lower housing 501, aligning the bottom of the flow meter 3 with the top of the fixed bend 2. Then insert the guide rod 5062 into the flange at the top of the bend 2 to keep the axis of the bend 2 coincident with the flow meter 3. At this time, the worker presses the air bag 5067 to inflate the air ring 5064, keeping the guide rod 5062 and the fixing bracket 5061 fixed, so that the air ring 5064 supports the flow meter 3, reduces the pressure of gravity on the flow meter 3, and keeps the guide rod 5062 stable. After determining the position, deflate the air ring 5064, pull out the guide rod 5062, and tighten the remaining screws to fix the bottom of the flow meter 3 to the bend 2. The guide rod can be inserted into the flange, indicating that the axis difference between the flow meter 3 and the bend 2 is small, and it can further limit the pipe, preventing the pipe from shifting after the clamping mechanism 6 fixes the pipe, increasing the displacement restriction of the pipe. After fine adjustment, the operation of installing the flow meter 3 on the upper and lower pipes can be completed quickly, reducing the difficulty of manual alignment and adjustment.

[0034] Alignment component 507 includes: The first telescopic column 5071 is installed in the middle of the inner wall of the upper housing 505; Arc-shaped plate 5072 is installed on top of the first telescopic column 5071.

[0035] Alignment component 507 also includes: Infrared emitter 5073 is symmetrically arranged at the upper and lower ends of the arc plate 5072. Clamping rod 5074 is evenly arranged on the inner wall of the arc plate 5072, and the bottom of clamping rod 5074 is rotatably connected to the inner wall of the arc plate 5072.

[0036] After the flow meter 3 is placed on the arc plate 5072, the clamping rod 5074 automatically clamps the outer wall of the flow meter 3, aligning the axis of the flow meter 3 with the axis of the arc plate 5072. This also ensures that the axis of the arc plate 5072 corresponds to the arrangement of the infrared transmitter 5073. When the infrared transmitter 5073 and the infrared receiver 510 are connected, it indicates that the axis of the pipe and the flow meter 3 are aligned. This allows workers to quickly determine whether the axis is aligned, reducing the labor cost of manually aligning the pipe. It also allows for a more intuitive judgment of whether the pipe is aligned before tightening the screws, avoiding the need for secondary disassembly and delaying the work process.

[0037] The specific workflow is as follows: In use, first rotate the rotating plate 504 180 degrees downwards to separate the upper housing 505 from the lower housing 501, so that the upper housing 505 and the lower housing 501 are in a vertical state. Place the upper housing 505 horizontally, and then place the flow meter 3 and the upper tube 4 inside the upper tube 4. The alignment component 507 holds the flow meter 3 in place. The upper tube 4 is clamped by the clamping mechanism 6 on the outer wall of the upper housing 505, and the limit component 506 cooperates to keep the axis of the upper tube 4 and the flow meter 3 aligned by the alignment component 507. Then the upper tube 4 and the flow meter 3 are installed. Initially, the retaining ring 601 is rotated along one end, moving it away from the upper housing 505 and opening it. Then, the upper tube 4 is placed in the slot of the upper housing 505. The second telescopic column 508 drives the clamping block 509 closer to the outer wall of the upper tube 4. The retaining ring 601 rotates, clamping the upper tube 4 between it and the upper housing 505. The second telescopic column 508 drives the clamping block 509 to move until the infrared receiver 510 on the clamping block 509 aligns with the infrared emitter on the alignment assembly 507. When the signal of device 5073 is connected, the axis of the upper pipe 4 is aligned with the axis of the flow meter 3. Then, the worker manually rotates the U-shaped rod 604, causing the U-shaped rod 604 to drive the pad 608 under the connecting rod 607 to approach the pipe and form a compression. Then, rotating the U-shaped rod 604 drives the rotating block 605 to insert into the limiting groove 603 inside the sleeve 602, so that the pad 608 is stuck on the outer wall of the pipe. Together with the clamping block 509, the upper pipe 4 is wrapped and clamped to keep the pipe axis aligned. After the upper pipe 4 and flow meter 3 are installed, the lower housing 501, together with the clamping mechanism 6, fixes the outer wall of the bend 2. Then, the worker uses external force to rotate the upper housing 505, along with the upper pipe 4 and flow meter 3, by 90 degrees, so that the rotating plate 504 rotates to contact the upper housing 505 and remains stationary. At this time, the upper housing 505 and the lower housing 501 keep the axis of the bend 2 and the upper pipe 4 aligned, and also ensure that the flow meter 3 and the top of the bend 2 are aligned. Then, the limiting component 506 is inserted into the flange connecting the bend 2 and the flow meter 3 to align the bottom axis of the bend 2 and the flow meter 3. Then, the screws are inserted into the flange for pre-fixing. Finally, the limiting component 506 is pulled out and all the screws are tightened.
