Description

Technical Field

[0001] This utility model relates to the field of water meter testing technology, specifically a vertical rotating meter clamping platform device. Background Technology

[0002] Water meters, as devices for measuring and recording water flow, play a crucial role in water management. With technological advancements, water meters have evolved from mechanical to smart water meters. Smart water meters not only improve measurement accuracy but also add functions such as remote monitoring and data transmission.

[0003] According to national or international metrological regulations, the accuracy of water meters needs to be tested, calibrated, and verified. Since water meters may exhibit flow rate differences at different installation angles, testing requires simulating different installation angles to ensure the accuracy of flow rate measurement. Currently, different angle pads are generally used to simulate different installation angles, but this method is inefficient. Therefore, a more convenient auxiliary device for adjusting the water meter angle is needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a vertical rotating clamping table device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a vertical rotating clamping table device, comprising: A support frame includes a horizontal base and a vertical frame, wherein the vertical frame is vertically fixedly connected to the horizontal base; The indexing plate is vertically fixed to the upper part of the vertical frame. The indexing plate is provided with a rotation center hole and a plurality of first indexing positioning holes distributed in a circle around the rotation center hole. A rotating shaft passes through the rotation center hole of the indexing plate and is set perpendicular to the indexing plate; A rotating frame plate is rotatably mounted on the rotating shaft via a bearing assembly; The first angle limiting mechanism is used to limit the rotating frame plate to different angular positions of the indexing plate; A water meter clamping assembly includes an upper clamping unit and a lower clamping unit. The upper clamping unit includes an upper fixed frame, an upper mounting block, an upper pressure plate, a left guide rod, a right guide rod, a clamping cylinder, an upper water supply pipe, and an upper connector. The upper fixed frame is fixedly installed on the upper end of a rotating frame plate. The upper mounting block is installed on the upper fixed frame. The left and right sides of the upper pressure plate are vertically and flexibly installed below the upper mounting block via the left and right guide rods, respectively. The cylinder body of the clamping cylinder is fixedly connected to the middle position of the upper mounting block. The extension and retraction of the clamping cylinder... The rod head is connected to the upper pressure plate, the upper water supply pipe is fixedly installed below the upper pressure plate, and the upper connector is installed at the lower end of the upper water supply pipe; the lower clamping unit includes a lower fixing frame, a lower sleeve, a lower water supply pipe, and a lower connector. The lower fixing frame is fixedly installed at the lower end of the rotating frame plate, the lower sleeve is installed on the lower fixing frame, the lower water supply pipe passes through the lower sleeve and is fixedly connected to the lower sleeve, and the lower connector is installed at the upper end of the lower water supply pipe. The water meter being measured is clamped between the upper connector and the lower connector.

[0006] This invention utilizes a novel technical solution where the indexing plate and rotating shaft provide a reference for the rotation of the rotating frame. Multiple first-index positioning holes enable multi-position angle positioning of the rotating frame, meeting the simulation requirements of different installation angles. The rotating frame is mounted on the rotating shaft via a bearing assembly, making angle adjustment smoother and reducing operational resistance. The water meter clamping assembly, in conjunction with a pressure cylinder, enables rapid clamping and releasing of the water meter. The left and right guide rods ensure the stability of the upper pressure plate's lifting process, preventing misalignment during the connection of the upper and lower connectors and ensuring reliable sealing of the water pipeline. This device can quickly adjust and stably fix the water meter's installation angle, significantly reducing angle adjustment time and effectively improving water meter detection efficiency. Simultaneously, it ensures pipeline sealing during the detection process, preventing leakage from affecting the accuracy of the detection data.

[0007] Furthermore, the bearing assembly includes a bearing housing, a front bearing, and a rear bearing. The outer rings of the front bearing and the rear bearing are coaxially and interference-fitted into the bore of the bearing housing. The inner rings of the front bearing and the rear bearing are coaxially sleeved on the rotating shaft. The outer periphery of the bearing housing mates with the mounting holes of the rotating frame plate. The outer end of the bearing housing has a flange surface that is abutted and fixed to the rotating frame plate.

[0008] By adopting the above-mentioned preferred solution, the dual-bearing structure better ensures the coaxiality of the rotating shaft, ensuring smooth rotation of the rotating frame plate, avoiding deviations in water meter angle adjustment due to shaft wobbling, and improving angle positioning accuracy.

[0009] Furthermore, the outer periphery of the rotating shaft is provided with a stop step surface for abutting the rear end face of the inner ring of the rear bearing, and the front end of the rotating shaft is provided with an external thread with an outer diameter smaller than the inner diameter of the front bearing. The front end of the rotating shaft is connected to a locking bolt via a thread, and the rear end face of the locking bolt abuts against the inner ring of the front bearing.

[0010] By adopting the above-mentioned preferred solution, the design of the locking bolt facilitates the disassembly and maintenance of the bearing assembly. When the bearing is worn and needs to be replaced, the bearing can be removed from the rotating shaft simply by unscrewing the locking bolt, reducing maintenance difficulty and cost.

[0011] Furthermore, the rotating shaft is provided with a rear stop portion on the rear side of the indexing plate, which abuts against the rear side of the indexing plate. The rotating shaft is provided with a cuboid portion at the rear end of the rear stop portion. The upper part of the vertical frame is provided with a horizontally arranged support beam. The cuboid portion is locked to the support beam with bolts so that the bottom surface of the cuboid portion is fixed against the upper surface of the support beam. When the cuboid portion abuts against the upper surface of the support beam, the axis of the rotating shaft is in a horizontal state.

[0012] By adopting the above-mentioned preferred scheme, the close contact between the rear stop and the indexing plate can limit the axial position of the rotating shaft, and the surface contact design between the cuboid part and the support beam can more stably transfer the load of the rotating shaft to the support beam, prevent the load of the front rotating frame plate from causing the front end of the rotating shaft to sink, and improve the stability of the rotating shaft installation.

[0013] Furthermore, the first angle limiting mechanism consists of multiple limiting pins, which are inserted into the first indexing positioning hole of the indexing plate and abut against the side of the rotating frame plate for limiting.

[0014] Using the above-mentioned preferred solution, the limit pin has a simple structure and is easy to operate. Simply insert the limit pin into the corresponding indexing positioning hole to fix the angle of the rotating frame plate.

[0015] Furthermore, an oblique connecting rod is fixedly connected between the horizontal base and the vertical frame.

[0016] By adopting the above-mentioned preferred solution, the overall rigidity of the support frame is effectively improved, and the bending deformation of the vertical frame after being loaded is reduced.

[0017] Furthermore, the upper clamping unit has an upper rotating support plate fixedly connected to its upper fixed frame, and the upper mounting block is rotatably mounted on the upper rotating support plate. The upper rotating support plate is provided with a plurality of second indexing positioning holes distributed in a circle, and also includes a second angle limiting mechanism for restricting the upper mounting block to different angular positions on the upper rotating support plate; the lower clamping unit has a lower rotating support plate fixedly connected to its lower fixed frame, and the lower sleeve is rotatably mounted on the lower rotating support plate.

[0018] By adopting the above-mentioned preferred scheme, the rotatable engagement between the upper mounting block and the upper rotating support plate, as well as the rotatable engagement between the lower sleeve and the lower rotating support plate, allows the water meter to rotate around its own axis after being clamped, thereby adjusting the circumferential angle of the water meter. This meets the requirements for simulating more complex installation angles and improves the comprehensiveness of the accuracy detection of water meter readings. The cooperation between the second indexing positioning hole and the second angle limiting mechanism enables precise positioning of the circumferential angle of the water meter, ensuring the consistency of each test angle. This structural design allows the device to adjust not only the installation angle of the water meter rotating along the vertical axis of its length, but also its own circumferential angle, enriching the detection dimensions and further improving the comprehensiveness and accuracy of the detection results.

[0019] Furthermore, the upper mounting block has a rotatable angle of 180° on the upper rotating support plate.

[0020] By adopting the preferred scheme described above, the 180° rotation range can avoid interference between the water pipe and the rotating frame plate caused by excessive rotation angle. The 180° rotation angle covers the required range for circumferential detection of the water meter, and can simulate the forward and reverse installation and intermediate transition angles that may occur during actual installation of the water meter, thus meeting the detection requirements of the water meter under different circumferential installation angles.

[0032] like Figure 4 As shown, in some other embodiments of this utility model, the bearing assembly 31 includes a bearing housing 311, a front bearing 312, and a rear bearing 313. The outer rings of the front bearing 312 and the rear bearing 313 are coaxially and interference-fitted into the bore of the bearing housing 311.

The outer periphery of the bearing housing 311 mates with the mounting hole of the rotating frame plate 40.

The beneficial effects of adopting the above technical solution are: the double bearing structure better ensures the coaxiality of the rotating shaft, ensures the smooth rotation of the rotating frame plate, avoids deviation in water meter angle adjustment due to shaft wobbling, and improves angle positioning accuracy.

[0033] like Figure 4 As shown, in some other embodiments of this utility model, the outer periphery of the rotating shaft 30 is provided with a stop step surface 301 for abutting against the rear end face of the inner ring of the rear bearing 313. The front end of the rotating shaft 30 is provided with an external thread with an outer diameter smaller than the inner diameter of the front bearing. A locking bolt 302 is threadedly connected to the front end of the rotating shaft 30, and the rear end face of the locking bolt 302 abuts against the inner ring of the front bearing 312. The beneficial effects of adopting the above technical solution are: the design of the locking bolt facilitates the disassembly and maintenance of the bearing assembly. When the bearing is worn and needs to be replaced, the bearing can be removed from the rotating shaft simply by unscrewing the locking bolt, reducing maintenance difficulty and cost.

[0034] like Figure 2 , Figure 4 As shown, in some other embodiments of this utility model, the rotating shaft 30 is provided with a rear stop 303 on the rear side of the indexing plate, which abuts against the rear side of the indexing plate. A cuboid portion 304 is provided at the rear end of the rotating shaft 30 near the rear stop 303. A horizontally arranged support beam 121 is provided on the upper part of the vertical frame 12.

When the cuboid portion 304 abuts against the upper surface of the support beam 121, the axis of the rotating shaft 30 is horizontal. The beneficial effects of the above technical solution are: the abutment of the rear stop and the indexing plate restricts the axial position of the rotating shaft; the surface contact design between the cuboid portion and the support beam more stably transfers the load of the rotating shaft to the support beam, preventing the load of the front rotating plate from causing the front end of the rotating shaft to sink, thus improving the stability of the rotating shaft installation.

[0035] In some other embodiments of this utility model, the first angle limiting mechanism 41 consists of multiple limiting pins, which are inserted into the first indexing positioning hole 21 of the indexing plate and abut against the side of the rotating frame plate 40 for limiting. The beneficial effects of adopting the above technical solution are: the limiting pin has a simple structure and is easy to operate; simply inserting the limiting pin into the corresponding indexing positioning hole is sufficient to fix the angle of the rotating frame plate.

The beneficial effects of adopting the above technical solution are: effectively improving the overall rigidity of the support frame and reducing the bending deformation of the vertical frame after bearing load.

[0037] Existing metering regulations and actual testing neglect to assess the impact of the water meter's circumferential installation angle on the water meter's reading error. For example... Figure 5 , Figure 6As shown, in some other embodiments of this utility model, an upper rotating support plate 59 is fixedly connected to the upper fixing frame 51 of the upper clamping unit 50, and an upper mounting block 52 is rotatably mounted on the upper rotating support plate 59. The upper rotating support plate 59 is provided with a plurality of second indexing positioning holes 591 distributed in a circular pattern.

The second angle limiting mechanism can also be a pin that cooperates with the second indexing positioning hole. The pin abuts against the edge of the upper mounting block or a matching insertion hole is opened on the upper mounting block to form a limit at different angles. A lower rotating support plate 65 is fixedly connected to the lower fixing frame 61 of the lower clamping unit 60, and a lower sleeve 62 is rotatably mounted on the lower rotating support plate 65. The beneficial effects of adopting the above technical solution are as follows: the rotatable fit between the upper mounting block and the upper rotating support plate, and the rotatable fit between the lower sleeve and the lower rotating support plate, allow the water meter to rotate around its own axis after being clamped, thereby adjusting the circumferential angle of the water meter, meeting the needs of more complex installation angle simulation, and improving the comprehensiveness of the accuracy detection of the water meter readings; the cooperation between the second indexing positioning hole and the second angle limiting mechanism can achieve precise positioning of the circumferential angle of the water meter, ensuring the consistency of each test angle; this structural design allows the device to not only adjust the installation angle of the water meter rotating along the vertical line of its length, but also adjust its own circumferential angle, enriching the detection dimensions and further improving the comprehensiveness and accuracy of the detection results.

[0038] like Figure 5 , Figure 6 As shown, in some other embodiments of this utility model, the upper mounting block 52 can rotate 180° on the upper rotating support plate 59. The beneficial effect of adopting the above technical solution is that the 180° rotation range avoids interference between the water pipe and the rotating support plate caused by excessive rotation angle. The 180° rotation angle covers the required range for circumferential detection of the water meter, simulating the possible forward and reverse installation and intermediate transition angles that may occur during actual installation of the water meter, thus meeting the detection requirements of the water meter under different circumferential installation angles.

[0039] The following describes the water meter testing process according to one embodiment of this utility model. It includes the following steps: S11, connect the upper and lower water supply pipes to the inlet and outlet water pipes of the water meter calibration device; S12, rotate the rotating frame plate to a vertical position, and limit it to a vertical position by the first angle limiting mechanism; S12, place one end of the water meter to be tested on the lower connector, and after placing it vertically, start the clamping cylinder to clamp the water meter to be tested between the upper connector and the lower connector; S13, turn on the water meter calibration device, conduct a water flow test, and compare the difference between the water meter flow reading under each flow state when the water meter is installed vertically and the standard value of the standard flow meter in the water meter calibration device. S14, rotate the rotating frame plate, adjust it to the next angle to be tested, and then limit it through the first angle limiting mechanism. Then conduct the water flow test and compare the difference between the water meter flow reading under each flow state and the standard value of the standard flow meter in the water meter calibration device.

[0040] S15, rotate the upper mounting block of the upper clamping unit to drive the clamped water meter to rotate along its axis to the next angle to be tested, and limit it by the second angle limiting mechanism. Repeat steps S13 and S14 to complete the measurement of the flow rate indication under the different rotation angles of the water meter around its axis in the installation state.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model.
