Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, and in particular to a flow meter disassembly and assembly device. Background Technology

[0002] When installing a flow meter, it is mainly secured by flanges installed at both ends and on the pipeline, with multiple bolts inserted into the flanges and then tightened with nuts.

[0003] During the disassembly and installation of the flow meter, the workers usually have to manually support the flow meter and move it between the two pipes. At the same time, they need to use their other hand to hold the bolts and insert them into the flange holes for connection and installation. This operation method is relatively difficult and very inconvenient.

[0004] Therefore, it is necessary to provide a new flow meter disassembly and assembly device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a flow meter disassembly and assembly device.

[0006] The flow meter disassembly and assembly device provided by this utility model includes: a fixing frame, wherein two fixing frames are provided and symmetrically distributed, and a support plate is movably connected between the two fixing frames; The mounting bracket is movably installed with mounting clips that connect the mounting bracket to the pipe. The support plate is provided with a movably connected support frame. A rotatably connected fixed drive rod is inserted inside the support frame. Fixed guide rods are fixedly connected on both sides of the fixed drive rod inside the support frame. Fixed clips are slidably connected on both sides of the fixed guide rod. The inner wall of the fixed clip is threaded to the outer side of the fixed guide rod, and the thread directions of the thread structures on both sides are opposite. Furthermore, a fixedly connected pad frame is installed inside the support frame.

[0007] Preferably, a threaded extrusion drive rod is inserted into the center of the support plate, and the top end of the extrusion drive rod is rotatably connected to the bottom of the support frame.

[0008] Preferably, both sides of the bottom extrusion drive rod of the support frame are fixedly connected to extrusion guide rods. The outer wall of the extrusion guide rod abuts against and slides with the inside of the support plate, and the outer side of the extrusion guide rod is provided with a scale strip.

[0009] Preferably, both sides of the fixing frame are equipped with fixedly connected support rods inside, the outer wall of the support rod abuts against and slides against the inside of the support plate, and the end of the support rod is fixedly installed with a baffle.

[0010] Preferably, a fixedly connected storage frame a is installed inside the fixed frame, and a fixedly connected storage frame b is installed on the outer wall of the fixed frame.

[0011] Preferably, a rotatably connected mounting drive rod is inserted inside the fixing frame, and a fixedly connected mounting guide rod is installed on both sides of the mounting drive rod inside the fixing frame. The two sides of the outer wall of the mounting guide rod abut against and slide against the inner wall of the corresponding mounting clip. The inner wall of the mounting clip is threadedly connected to the outer wall of the mounting drive rod, and the thread directions of the threaded structures on both sides are opposite.

[0012] Compared with related technologies, the flow meter disassembly and assembly device provided by this utility model has the following advantages: 1. By setting up a pad frame and a fixing clip, this utility model allows the pad frame to be moved to the bottom of the flow meter and the fixing clip to be driven during use, thereby supporting the flow meter. This reduces the fatigue and difficulty of operation for workers when installing the flow meter.

[0013] 2. By supporting the flow meter, this utility model allows the operator to adjust the position of the flow meter as needed during installation, so that the flow meter can be positioned between the flanges of the two pipes at the required angle.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 4 The present invention provides a flow meter disassembly and assembly device, which includes: a fixed frame 1, two fixed frames 1 are provided and symmetrically distributed, and a support plate 14 is movably connected between the two fixed frames 1.

[0020] In the embodiments of this utility model, please refer to Figures 1 to 4 The mounting bracket 1 has a mounting clip 2 that connects it to the pipe. The support plate 14 has a support frame 3 that is movably connected. The support frame 3 has a fixed drive rod 32 that is rotatably connected. The fixed drive rod 32 inside the support frame 3 has fixed guide rods 33 that are fixedly connected on both sides. The fixed guide rods 33 have fixed clips 34 that are slidably connected on both sides. The inner wall of the fixed clips 34 is threaded to the outer side of the fixed guide rods 33, and the thread directions of the threaded structures on both sides are opposite. The support frame 3 has a fixed pad frame 31 that is fixedly connected. The support plate 14 has a threaded extrusion drive rod 35 that is inserted in the center. The top of the extrusion drive rod 35 is rotatably connected to the bottom of the support frame 3. The extrusion guide rods 36 that are fixedly connected are installed on both sides of the extrusion drive rod 35 at the bottom of the support frame 3. The outer wall of the extrusion guide rod 36 abuts against and is slidably connected to the inside of the support plate 14. The extrusion guide rod 36 has a scale strip on its outer side.

[0021] It should be noted that: by setting the fixing clip 34 inside the support frame 3, during installation, when the operator controls the fixed drive rod 32 to rotate, it drives the fixing clip 34 to move on the fixed guide rod 33 through the thread structure with opposite threads on both sides of the outer wall, thus achieving the clamping and fixing of the flow meter. Then, the squeezing drive rod 35 can be controlled to drive the support frame 3 and its internal components to move up and down as needed, thereby adjusting the vertical position of the flow meter and facilitating quick disassembly of the flow meter. During the later installation of the flow meter, the squeezing drive rod 35 can be rotated in reverse. During this process, the operator can mark and record the scale before the flow meter is removed using the scale strip. Later, after the replacement flow meter is placed on the pad frame 31 and fixed, the squeezing drive rod 35 is rotated to move the support frame back to its original position. By comparing the scale, the support frame can be easily reset to the required position, allowing the flow meter's axis to overlap with the center of the pipe. After the pad frame 31 supports the flow meter, the clamping force of the fixing clip 34 on the flow meter only needs to be slightly reduced, and then the flow meter can be moved to rotate the flange hole position in the flow meter. This allows the flange in the flow meter to be aligned smoothly with the flange on the pipe, making it easier for the operator to insert bolts later. The entire process does not require the operator to manually lift the flow meter, which not only reduces the operator's lifting fatigue but also makes the installation of the flow meter more flexible and convenient.

[0022] In the embodiments of this utility model, please refer to Figures 1 to 4 Both sides of the fixed frame 1 are equipped with fixedly connected support rods 13. The outer wall of the support rod 13 abuts against and slides with the inside of the support plate 14, and the end of the support rod 13 is fixedly installed with a baffle 131.

[0023] It should be noted that: through the movement of the support rod 13, when the flow meter is separated from the pipeline during use, the pipeline unfolds to both sides in a separated state, allowing the fixing frame 1 to unfold synchronously with the pipeline. The baffle 131 prevents the support rod 13 from slipping off the support plate 14 when the fixing frame 1 moves, ensuring that the support plate 14 is always located between the two fixing frames 1. During the later installation of the flow meter, the support plate 14 supports the fixing clip 34 and the flow meter. When the fixed drive rod 32 rotates, it drives the support frame 3 to move, allowing the flow meter to move smoothly between the two pipelines.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 The fixed frame 1 has a fixedly connected storage frame a11 installed inside, and a fixedly connected storage frame b12 installed on the outer wall of the fixed frame 1.

[0025] It should be noted that since storage boxes a11 and b12 are located in different positions within the fixing frame 1, when the fixing frame 1 is installed vertically or horizontally, the disassembled bolts and nuts can be placed in storage boxes a11 and b12 to prevent them from being lost due to careless placement.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 4 The mounting bracket 1 is equipped with a rotating drive rod 21. Both sides of the mounting drive rod 21 are fixedly connected to the mounting guide rod 22. The outer walls of the mounting guide rod 22 abut against and slide against the inner walls of the corresponding mounting clips 2. The inner walls of the mounting clips 2 are threadedly connected to the outer walls of the mounting drive rod 21, and the thread directions of the threaded structures on both sides are opposite.

[0027] It should be noted that: by opening the opposite thread structure on both sides of the outer wall of the installation drive rod 21, when the installation drive rod 21 rotates during use, it will drive the installation clamp 2 to move relative to or opposite to each other on the outer wall of the installation guide rod 22. When the installation clamp 2 abuts against the outer wall of the pipe, the device can be successfully fixed on the pipe, so that the components in the fixing frame 1 can work stably in the later stage. It should also be noted that the drive rod 21, the fixed drive rod 32, and the extrusion drive rod 35 are all fitted with corrugated protective covers (not shown in the figure) to protect the threads on their outer walls. This reduces the risk of thread jamming caused by dust particles falling on the threads during later use, thus allowing the drive rod 21, the fixed drive rod 32, and the extrusion drive rod 35 to rotate stably.

[0028] The working principle of the flowmeter disassembly and assembly device provided by this utility model is as follows: When using this device, the operator can first move the fixing frame 1 to the bottom of the pipe in the flow meter to be disassembled, and move the mounting clip 2 to the outside of the pipe. Then, the operator can control the mounting drive rod 21 to rotate. The rotating mounting drive rod 21 can drive the mounting clips 2 on both sides of its outer wall to move relative to each other on the mounting guide rod 22 through the thread structure with opposite threads on both sides of its outer wall. When the outer wall of the mounting clip 2 abuts against the outer wall of the pipe, the fixing frame 1 can be clamped and installed. Then the extrusion drive rod 35 can be controlled to rotate. The rotating extrusion drive rod 35 can move vertically inside the support plate 14 through the threaded structure, thereby driving the support frame 3 at its top to move synchronously until the top of the pad frame 31 inside the support frame 3 abuts against the outer wall of the flow meter, at which point the rotation of the extrusion drive rod 35 can be stopped. Then the fixed drive rod 32 can be controlled to rotate. The rotating fixed drive rod 32 will drive the fixed clamping pieces 34 on both sides of its outer wall to move relative to the fixed guide rod 33 through the thread structure with opposite threads on both sides of its outer wall. The flow meter can be clamped and fixed after the outer wall of the fixed clamping piece 34 abuts against the outer wall of the flow meter. After clamping and fixing the flow meter, the operator can unscrew the bolts and nuts connected to the flange one by one to release the flange from the fixation. At the same time, the disassembled bolts and nuts can be placed in the required storage boxes a11 and b12 for storage. After releasing the fixation of the flow meter and the pipeline connection flange, the operator can rotate the extrusion drive rod 35 again, so that the flow meter can be moved through the support frame 3 and the fixing clip 34 inside, thereby realizing the disassembly of the flow meter. Similarly, when the flow meter needs to be installed later, the new flow meter can be placed on the pad frame 31 and then clamped and fixed by the fixing clip 34. Then the fixing drive rod 32 can be rotated to drive the support frame 3 to move, so that the flow meter clamped inside can be moved smoothly, and the flow meter can be moved stably between the two pipes, thereby achieving temporary support for the flow meter. When the axis of the flow meter overlaps with the axis of the pipe, the operator can observe the position of the bolt insertion hole in the flange. If there is a deviation in position, the fixing clamp 34 can be slightly loosened, so that while the fixing clamp 34 clamps and supports the flow meter, the flow meter can move freely. This allows the operator to adjust the position of the hole in the flange as needed, making the flange alignment and adjustment more flexible. Therefore, it makes the subsequent bolt insertion and tightening more flexible and convenient. After the bolts are fixed, the installation drive rod 21 can be rotated in the reverse direction to separate the installation clamp 2 from the pipe, thus separating the device from the pipe. At this point, the use of the device is complete.
