Description

Technical Field

[0001] This utility model relates to the field of vortex flow meter maintenance technology, specifically a vortex flow meter maintenance tool. Background Technology

[0002] A vortex flow meter is a velocity-type flow meter based on the von Kármán vortex street theory, utilizing the natural vibration principle of fluids. It uses piezoelectric crystals or differential capacitors as detection components. The core component, the vortex flow meter probe, converts the pressure signal of the vortex into an electrical signal. This signal is then processed and calculated by circuitry such as an amplifier and integrator to finally output and display the flow measurement result. During long-term use, vortex flow meters are prone to problems such as decreased measurement accuracy and fault alarms due to media corrosion, impurity deposition, and component wear. Regular maintenance is required, necessitating the use of maintenance tools.

[0003] Currently, when overhauling vortex flow meters, personnel usually disassemble them and place them directly on the workbench, or use simple supports during maintenance. Since different sizes of flow meters need to be supported, but the specifications of the supports are usually quite uniform, there are limitations in their use during subsequent assembly and handling.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 As shown, a vortex flowmeter maintenance fixture includes a maintenance frame 1. A support mechanism is fixedly connected inside the maintenance frame 1. An adjustment mechanism is also fixedly connected inside the maintenance frame 1. A lifting mechanism is fixedly connected inside the maintenance frame 1. Both the lifting mechanism and the adjustment guide rail 2 are used to lift the flowmeter. The maintenance frame 1 is used to support the adjustment mechanism and the lifting mechanism. By adopting the structure of the maintenance frame 1, the support mechanism, the adjustment mechanism and the lifting mechanism, the functions of supporting the adjustment mechanism and the lifting mechanism and lifting the flowmeter body 2017 are realized.

[0018] The adjustment mechanism includes an adjustment guide rail 2, a fixed support 201, a first adjustment screw 2011, and a first adjustment handwheel 2012. The adjustment guide rail 2 is slidably disposed within the maintenance frame 1. The fixed support 201 is fixedly disposed within the middle section of the adjustment guide rail 2. A sliding groove is provided inside the adjustment guide rail 2. The first adjustment screw 2011 is rotatably disposed within the adjustment guide rail 2. The first adjustment handwheel 2012 is fixedly disposed on the outer wall of the first adjustment screw 2011. By adopting the structure of the adjustment guide rail 2, the fixed support 201, the first adjustment screw 2011, and the first adjustment handwheel 2012, the function of using the first adjustment handwheel 2012 to drive the first adjustment screw 2011 to rotate is realized, providing power and a foundation for subsequent adjustment of the position of the transverse movable support 2013.

[0019] The adjustment mechanism also includes a transverse movable support 2013, a guide slider 2014, and a movable support 2015. There are two transverse movable supports 2013. The guide sliders 2014 are symmetrically fixed on the outer wall of the transverse movable support 2013. The transverse movable support 2013 is slidably disposed in the adjustment guide rail 2 through the guide sliders 2014. The interior of the transverse movable support 2013 has a screw hole that matches the first adjustment screw 2011. The screw holes inside the transverse movable support 2013 have opposite thread directions. By adopting the structure of the transverse movable support 2013 and the guide slider 2014, the transverse movable support 2013 can slide smoothly in the adjustment guide rail 2 with the help of the guide slider 2014. The position can be adjusted according to the size of the flow meter body 2017 to adapt to the support function.

[0020] The movable support 2015 has an arc-shaped structure and is fixedly installed at the top of the transverse movable support 2013. The adjustment mechanism also includes an anti-slip pad 2016, which is fixedly installed on the inner wall of the movable support 2015. By adopting the structure of the arc-shaped movable support 2015 and the anti-slip pad 2016, the flow meter body 2017 is supported in a way that conforms to its shape, while the anti-slip pad 2016 prevents the flow meter body 2017 from sliding.

[0021] The adjustment mechanism also includes a flow meter body 2017, a guide block 2018, and a guide slider 2019. The flow meter body 2017 is placed at the top of the transverse movable support 2013 and the fixed support 201. The guide block 2018 is symmetrically fixed at the left and right ends of the adjustment guide rail 2. The guide slider 2019 is fixedly set on the outer wall of the guide block 2018. By adopting the structure of the flow meter body 2017, the guide block 2018, and the guide slider 2019, the function of placing the flow meter body 2017 at the top of the transverse movable support 2013 and the fixed support 201 is realized, and the function of guiding the adjustment guide rail 2 to slide in the maintenance frame 1 is achieved.

[0022] The adjusting guide rail 2 is slidably mounted in the maintenance frame 1 via the guide block 2018 and the guide slider 2019. By adopting the structure of the guide block 2018 and the guide slider 2019 working together, the adjusting guide rail 2 can slide smoothly in the maintenance frame 1, which facilitates the adjustment of the lateral position of the flow meter body 2017 to adapt to the function of maintenance operation.

[0023] The lifting mechanism includes a fixed guide rail 3 and a second adjusting screw 301. The fixed guide rail 3 is fixedly installed on the inner wall of the maintenance frame 1. The fixed guide rail 3 and the adjusting guide rail 2 are perpendicularly arranged, and the fixed guide rail 3 has a longitudinal groove inside. By adopting the structure of the fixed guide rail 3 and the second adjusting screw 301, the fixed guide rail 3 is perpendicularly matched with the adjusting guide rail 2, which provides the function of installation foundation and guidance for the longitudinal adjustment of the flow meter body 2017 position.

[0024] The second adjusting screw 301 is rotatably mounted inside the fixed guide rail 3. The lifting mechanism also includes a second adjusting handwheel 3011 and a longitudinal movable support 3012. The second adjusting handwheel 3011 is fixedly mounted on the outer wall of the second adjusting screw 301. By adopting the structure of the second adjusting screw 301, the second adjusting handwheel 3011 and the longitudinal movable support 3012, the function of using the second adjusting handwheel 3011 to drive the second adjusting screw 301 to rotate and provide power for the sliding of the longitudinal movable support 3012 is realized.

[0025] The longitudinal movable support 3012 is slidably disposed within the fixed guide rail 3. The longitudinal movable support 3012 has the same structure as the transverse movable support 2013. The interior of the longitudinal movable support 3012 is provided with a screw hole that matches the second adjusting screw 301. By adopting the structure of the longitudinal movable support 3012 cooperating with the second adjusting screw 301, the longitudinal movable support 3012 can slide smoothly within the fixed guide rail 3 and can adjust its position longitudinally to meet the lifting requirements of flow meter bodies 2017 of different sizes.

[0026] The support mechanism includes a guide groove 101 and a support pad 1011. The guide groove 101 is symmetrically opened on the left and right sides of the maintenance frame 1, and the support pad 1011 is fixedly set at the four corners of the bottom end face of the maintenance frame 1. By adopting the structure of the guide groove 101 and the support pad 1011, the mechanism provides guidance for the sliding of the adjustment guide rail 2, and at the same time, the support pad 1011 ensures the stable placement of the maintenance frame 1 and guarantees the stability of the overall tooling.

[0027] Working principle: Before carrying out maintenance work, the maintenance frame 1 is placed on a flat operating surface through the support pad 1011 in the support mechanism. After the support pad 1011 contacts the surface, it forms a stable support for the maintenance frame 1, preventing the maintenance frame 1 from shifting or shaking during subsequent operations.

[0028] The operator places the flow meter body 2017 to be inspected onto the fixed support 201 of the regulating mechanism and the movable support 2015 at the top of the transverse movable support 2013. The anti-slip pad 2016 on the inner wall of the movable support 2015 will fit tightly against the outer wall of the flow meter body 2017, thereby increasing the contact friction between the two and preventing the flow meter body 2017 from sliding or shifting in the supported state.

[0029] If the lateral dimension of the flowmeter body 2017 does not match the position of the lateral movable support 2013 in the initial state, the operator rotates the first adjusting handwheel 2012. The first adjusting handwheel 2012 drives the first adjusting screw 2011, which is fixedly connected to it, to rotate inside the adjusting guide rail 2. Since the lateral movable support 2013 has a screw hole that matches the first adjusting screw 2011, and the lateral movable support 2013 forms a sliding fit with the sliding groove of the adjusting guide rail 2 through the guide slider 2014, the rotational motion of the first adjusting screw 2011 is converted into the lateral linear motion of the lateral movable support 2013 along the adjusting guide rail 2, so that the two lateral movable supports 2013 move synchronously towards or away from the fixed support 201, until the movable support 2015 can completely fit the lateral outer wall of the flowmeter body 2017, thus realizing the adaptation and support of the flowmeter body 2017 with different lateral dimensions. When the longitudinal position of the flowmeter body 2017 needs to be adjusted for maintenance, the operator rotates the second adjusting handwheel 3011. The second adjusting handwheel 3011 drives the second adjusting screw 301 to rotate inside the fixed guide rail 3. The longitudinal movable support 3012 has a screw hole that matches the second adjusting screw 301 inside, and the longitudinal movable support 3012 is slidably set in the longitudinal groove of the fixed guide rail 3. The rotational motion of the second adjusting screw 301 is converted into the longitudinal linear motion of the longitudinal movable support 3012 along the fixed guide rail 3. The longitudinal movable support 3012 has the same structure as the transverse movable support 2013. Its top can provide auxiliary support for the longitudinal part of the flowmeter body 2017. By adjusting the position of the longitudinal movable support 3012, the maintenance needs of different longitudinal positions of the flowmeter body 2017 can be met, ensuring that the longitudinal force balance of the flowmeter body 2017 is maintained during maintenance. If the lateral position of the flow meter body 2017 needs to be adjusted to suit different maintenance procedures, the operator pushes the adjustment guide rail 2. The adjustment guide rail 2 forms a sliding fit with the guide grooves 101 on both sides of the maintenance frame 1 through the guide blocks 2018 at the left and right ends and the guide slider 2019. The adjustment guide rail 2 moves laterally along the guide grooves 101, and at the same time drives the fixed support 201, the lateral movable support 2013 and the flow meter body 2017 on it to move synchronously until the flow meter body 2017 is adjusted to a position that is convenient for the operator to perform maintenance operations. The fixed guide rail 3 of the lifting mechanism and the adjusting guide rail 2 of the adjusting mechanism are set vertically. The two work together to drive the flow meter body 2017 to achieve all-round position adjustment in the horizontal and vertical directions on the horizontal plane. The flow meter components disassembled during maintenance can be placed in categories on the top of the movable support 2015 of the adjusting mechanism and the longitudinal movable support 3012 of the lifting mechanism to prevent the components from being scattered on the workbench. After the flowmeter maintenance is completed, the operator rotates the first adjusting handwheel 2012 in the reverse direction, causing the first adjusting screw 2011 to rotate in the reverse direction, so that the transverse movable support 2013 returns to its initial position along the adjusting guide rail 2. At the same time, the operator rotates the second adjusting handwheel 3011 in the reverse direction, causing the second adjusting screw 301 to rotate in the reverse direction, so that the longitudinal movable support 3012 returns to its initial position along the fixed guide rail 3. Finally, the flowmeter body 2017, which has been maintained, is removed from the movable support 2015, thus completing the entire maintenance process.
