Description

Technical Field

[0001] This application relates to the technical field of industrial flowmeter assembly, and particularly to an auxiliary positioning device for installing a throttling element. Background Art

[0002] In the existing related technical fields, flexible lifting straps are generally used to fix the inner hole of the throttling element to achieve the assembly of the throttling element and the pipe body. After the free end of the flexible sling passes through the hole on the throttling element and is fixed, the throttling element on the flexible sling is placed inside the pipe body through a lifting device, and then the throttling element and the pipe body are fixedly connected by welding. This method realizes the connection between the two to a certain extent. However, when using a flexible lifting strap to install the throttling element, due to the elasticity of the flexible lifting strap itself, it is impossible to ensure that the throttling element always remains in a horizontal position during lifting, resulting in the throttling element tilting or shifting during the assembly with the pipe body, so that the throttling element cannot be accurately docked and assembled with the pipe body according to the predetermined position, affecting the assembly accuracy of the throttling element and the pipe body and resulting in errors in the detection results. Summary of the Invention

The second support member is movably arranged on the first support member, and the second support member can move in a direction towards or away from the workbench. The second support member is suitable for providing horizontal support for the throttling element;

[0005] The second support member is movably connected to the first support member through the height adjustment component.

[0006] In a possible implementation manner, the height adjustment component includes a first fully threaded bolt and two first nuts; the first support member is provided with an oblong first adjustment hole, the length direction of the first adjustment hole is perpendicular to the plane where the workbench is located, the second support member is provided with a second adjustment hole, the first fully threaded bolt is sequentially passed through the first adjustment hole and the second adjustment hole, and both of the two first nuts are sleeved on the first fully threaded bolt and are respectively in close contact with the first support member and the second support member.

[0029] A throttling element installation auxiliary positioning device is applicable to providing horizontal support for a throttling element 510 during the assembly of the throttling element 510 and a pipe body 520. As Figures 1 to 6 shown, it includes: a workbench 100 and two positioning support assemblies 200; the two positioning support assemblies 200 each include a first support member 210, a second support member 220, and a height adjustment assembly 300; the main body of the first support member 210 is in an L-shaped plate structure, and the two first support members 210 are oppositely arranged on the workbench 100; the second support member 220 is movably arranged on the first support member 210, and the second support member 220 can move in a direction towards or away from the workbench 100, and the second support member 220 is applicable to providing horizontal support for the throttling element 510; the second support member 220 is movably connected to the first support member 210 through the height adjustment assembly 300.

[0030] It should be noted here that as Figure 1 shown, the workbench 100 is applicable to providing a flat and stable installation foundation for the positioning support assemblies 200. The two positioning support assemblies 200 are oppositely installed on the workbench 100. The first support member 210 with a cross-sectional L-shaped plate structure has good stability and bearing capacity, so as to ensure that the first support member 210 provides a stable support for the second support member 220. The two oppositely arranged first support members 210 can form a stable support frame on the workbench 100, further enhancing the stability of the overall structure. The openings of the two first support members 210 face away from each other. The design of the openings facing away from each other can also avoid interference between the first support members 210, making the layout of the workbench 100 more reasonable. As Figure 2 、 Figure 3As shown, the throttle member 510 is placed on two second support members 220. The two second support members 220 provide stable horizontal support for the throttle member 510. Then, the pipe body 520 is sleeved on the throttle member 510, effectively preventing the throttle member 510 from shifting or tilting during the assembly with the pipe body 520, improving the assembly accuracy. Through the mutual cooperation of the first support member 210 and the second support member 220, the throttle member 510 can maintain its predetermined position and attitude during the assembly with the pipe body 520, effectively avoiding the displacement or tilt of the throttle member 510 caused by external forces. At the same time, the second support member 220 also lays the foundation for the concentric assembly of the throttle member 510 and the pipe body 520, ensuring that when the pipe body 520 is sleeved on the throttle member 510, the two can maintain a high degree of concentricity, reducing the assembly error between the throttle member 510 and the pipe body 520, avoiding unnecessary rework and cost waste, and ensuring the accuracy during the assembly of the throttle member 510 and the pipe body 520.

[0031] As Figure 1 shown, the second support member 220 is installed on the first support member 210 through the height adjustment assembly 300. The height adjustment assembly 300 is suitable for adjusting the height of the second support member 220 on the first support member 210. By adjusting the position of the second support member 220 on the first support member 210, the height of the second support member 220 can be adjusted and fixed. The design of the height adjustment assembly 300 allows the staff to flexibly adjust the height of the second support member 220 on the first support member 210 according to actual needs, so as to ensure the assembly between the throttle member 510 and pipe bodies 520 of different sizes to adapt to different working scenarios and assembly requirements.

[0032] In a possible implementation manner, as Figure 4 、 Figure 5 shown, the height adjustment assembly 300 includes a first fully threaded bolt 310 and two first nuts 320; on one side where the first support member 210 connects to the second support member 220, a first adjustment hole 211 is opened. The body length direction of the first adjustment hole 211 is perpendicular to the plane where the workbench 100 is located. The second support member 220 is provided with a second adjustment hole 221. The first fully threaded bolt 310 passes through the first adjustment hole 211 and the second adjustment hole 221 in sequence. Both of the two first nuts 320 are sleeved on the first fully threaded bolt 310 and are respectively in close fit with the first support member 210 and the second support member 220.

[0033] It should be noted here that the first support member 210 is composed of a horizontal support and a vertical support that are perpendicular to each other. The horizontal support is connected to the workbench 100, and the vertical support is connected to the second support member 220. The first adjustment hole 211 is opened on the vertical support, and the first adjustment hole 211 extends along the body length direction of the vertical support. Correspondingly, the second adjustment hole 221 extends along the width direction of the second support member 220, so that the first adjustment hole 211 is opposite to the second adjustment hole 221. The first full-thread bolt 310 passes through the first adjustment hole 211 and the second adjustment hole 221 in sequence, and the height of the second support member 220 on the first support member 210 is adjusted by the position of the first full-thread bolt 310 in the first adjustment hole 211 and the second adjustment hole 221. That is, the first full-thread bolt 310 is connected to the second support member 220 on the first support member 210. The threaded bolt 310 moves in the first adjustment hole 211 and the second adjustment hole 221 to drive the second support member 220 to move so as to adjust the height of the second support member 220 on the first support member 210. The two first nuts 320 are respectively sleeved on both sides of the first full-thread bolt 310. By screwing the two first nuts 320, the two first nuts 320 are tightly fitted with the sides of the first support member 210 and the second support member 220 that are away from each other to provide sufficient clamping force, so that the second support member 220 is fixedly installed on the first support member 210.

[0034] Preferably, Figure 5 As shown, the first adjustment hole 211 and the second adjustment hole 221 are both configured as oblong hole structures.

[0035] It should be noted that in order to further improve the connection stability between the second support member 220 and the first support member 210 of each positioning support assembly 200, the number of height adjustment assemblies 300 can also be increased. The specific number is not limited in this application, that is, the second support member 220 and the first support member 210 can be connected through multiple height adjustment assemblies 300.

[0036] In a possible implementation, the main body of the second support member 220 is a rectangular plate-shaped structure, and the length direction of the second support member 220 is parallel to the horizontal plane where the workbench 100 is located. It should be noted here that the rectangular plate-shaped structure has a large bearing area, which can effectively disperse and bear the weight of the throttle 510 from above. The second support member 220 provides a horizontal support force, and the horizontal support helps to reduce the vibration and shaking of the throttle 510 during the assembly process, thereby improving its assembly accuracy and overall stability, and ensuring the stability of the support of the throttle 510 during the welding process, so as to avoid the situation where the throttle 510 is not separated from the pipe 520 due to inadequate welding.

[0037] In a possible implementation, the two positioning support assemblies 200 are movably connected to the workbench 100 through the spacing adjustment assembly 400; the two positioning support assemblies 200 can move in a direction of approaching or moving away from each other. The staff adjusts the distance between the two positioning support assemblies 200 according to different models and sizes of the throttle 510 to provide more stable support. At the same time, it can flexibly adapt to throttles 510 of different sizes and models without replacing the entire workbench 100 or the positioning support assembly 200, thereby improving the versatility and adaptability of the overall structure.

[0038] In one possible implementation, the spacing adjustment assembly 400 includes a second fully threaded bolt and a second nut 420; a sliding groove 110 is opened on the workbench 100, and a third adjustment hole 212 is opened on the side of the first support member 210 connected to the workbench 100, the second fully threaded bolt passes through the third adjustment hole 212 and extends into the sliding groove 110, and the second nut 420 is sleeved on the second fully threaded bolt and is located on the side of the first support member 210 away from the workbench 100, and is suitable for locking the first support member 210 on the workbench 100. It should be noted here that the two positioning support assemblies 200 are movably connected to the workbench 100 through the spacing adjustment assembly 400 respectively. A sliding groove 110 is provided on the workbench 100, and the sliding groove 110 extends along the body length direction of the workbench 100. The spacing adjustment assembly 400 penetrates the positioning support assembly 200 and then probes into the sliding groove 110 on the workbench 100. By adjusting the positions of the two positioning support assemblies 200 on the workbench 100, the spacing between the two positioning support assemblies 200 is adjusted and fixed.

[0039] Further, such as Figure 1 , Figure 4As shown, a third adjustment hole 212 is provided in the horizontal support of the first support member 210, and the third adjustment hole 212 extends along the length direction of the horizontal support. The second all-thread bolt is slidably installed in the sliding groove 110, and the length direction of the second all-thread bolt is perpendicular to the length direction of the sliding groove 110. The second all-thread bolt penetrates through the third adjustment hole 212 and extends into the sliding groove 110. The distance between the two first support members 210 is adjusted by adjusting the position of the second all-thread bolt in the third adjustment hole 212 and the sliding groove 110. That is, when the second all-thread bolt moves in the third adjustment hole 212 and the sliding groove 110 to drive the first support member 210 to move so as to adjust the position of the first support member 210 on the workbench 100, a second nut 420 is sleeved on the second all-thread bolt and is located on the side of the horizontal support of the first support member 210 away from the workbench 100. The second nut 420 is adapted to lock the first support member 210 on the workbench 100. By tightening the second nut 420, the second nut 420 is closely attached to the horizontal support of the first support member 210 to provide sufficient clamping force, thereby fixing the first support member 210 on the workbench 100.

[0040] Further, there are four spacing adjustment assemblies 400, and the first support member 210 of each positioning support assembly 200 is connected to the workbench 100 through two spacing adjustment assemblies 400.

[0041] In a possible implementation manner, both the first all-thread bolt 310 and the second all-thread bolt are all-thread bolts of model M20 in the prior art, and both the first nut 320 and the second nut 420 are nuts of model M20 in the prior art.

[0042] In a possible implementation manner, the main body of the workbench 100 is in a cuboid structure.

[0043] In a possible implementation manner, the main body of the sliding groove 110 is in a strip-shaped groove structure, and the length direction of the sliding groove 110 is parallel to the length direction of the workbench 100. It should be noted here that, as Figure 3 shown, the cross-section of the sliding groove 110 is in a T-shaped groove structure. The sliding groove 110 provides accurate guidance for the positioning support assembly 200 to ensure that it can maintain an accurate path and trajectory during movement. The design of the sliding groove 110 parallel to the workbench 100 helps to evenly disperse the stress to the entire workbench 100 when the workbench 100 bears a load, ensuring the stability of the overall structure of the workbench 100.

[0044] In a possible implementation manner, there are more than two sliding grooves 110, and the more than two sliding grooves 110 are arranged in sequence along the body width direction of the workbench 100. The design of the multiple sliding grooves 110 enables the workbench 100 to be flexibly configured and adjusted according to different processing requirements, so as to adapt to a variety of application scenarios.

[0045] Further, as Figure 2 , Figure 3 shown, two pressure taking holes 521 are formed on one side of the pipe body 520, and the two pressure taking holes 521 are arranged along the body length direction of the pipe body 520. Moreover, the throttling member 510 needs to be installed between the two pressure taking holes 521. During the installation process, the throttling member 510 can be calibrated by observing the pressure taking holes 521 to ensure that the horizontal plane where the throttling member 510 is located is between the two pressure taking holes 521, so as to more accurately reflect the pressure difference on both sides of the throttling member 510. The throttling member 510 located between the two pressure taking holes 521 is fixedly connected to the pipe body 520 by welding, so as to realize the assembly of the throttling member 510 and the pipe body 520, ensure the concentricity setting of the throttling member 510 and the pipe body 520, avoid the error in the assembly of the throttling member 510 and the pipe body 520, and improve the accuracy of detection.
