Description

Technical Field

[0001] The utility model relates to the technical field of flange inspection, and particularly relates to an inspection device for various flanges. Background Technique

[0002] A flange, also known as a flange convex disc or a flange, is an annular structure used for connecting components such as equipment and pipelines. A flange is a part for connecting between shafts, used for connecting between pipe ends, and there are also flanges used at the inlets and outlets of equipment for connecting between two equipment. At the same time, it is widely used in fields such as construction, light and heavy industries, plumbing, and electric power, and is an important component for connecting equipment or components such as pipelines, valves, and pumps. As an important component for pipeline connection, there are various types of flanges, and each type has its specific application scenarios and characteristics. To ensure quality, safety, and reliability, it is necessary to inspect flanges.

[0003] Common inspection devices for various flanges are usually composed of structures such as a support assembly, a fixing device, a detection and measurement system, a control system, and an auxiliary system. First, the flange is fixed through the support assembly and the fixing device, and then the detection and measurement system is driven by the control system and the auxiliary system to detect and measure the flange, so as to obtain the detection and measurement data of the flange.

[0004] Traditional inspection devices for various flanges usually use measuring tools, such as calipers, tape measures, or vernier calipers, etc. to inspect flanges and obtain the inspection data of flanges, which not only limits the inspection accuracy but also makes the measurement speed slow. To solve the above problems, some inspection devices for various flanges add a detection and measurement system to the device, and the detection and measurement system is composed of structures such as a detection device, a probe, and a measuring instrument, and then inspect the flange, which not only improves the inspection accuracy but also improves the measurement speed. However, in this way, since the flange is usually fixed on the inspection device to ensure the accuracy of the detection data, and the detection structure is usually fixed on the inspection device, it is not convenient to adjust the detected part of the flange. Therefore, an inspection device for various flanges is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an inspection device for various flanges to solve the technical problem that it is not convenient to adjust the detected part of the flange.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An inspection device for various flanges, comprising:

[0008] The skateboard is arranged at the upper part of the central position on the outer surface of the guide post, and a dial indicator is installed at the central position on the outer side of the bottom of the skateboard;

[0009] The annular toothed plate is arranged directly below the bottom of the support disc, and a connecting rod is connected between the annular toothed plate and the guide post. A driving wheel is additionally arranged at the center of the inner cavity of the annular toothed plate. Driven wheels are meshed around the driving wheel, and the driven wheels are meshed with the tooth blocks on the inner wall of the annular toothed plate. The bottom of the driving wheel is coaxially connected with a driving motor. By placing the flange at the center of the top of the inspection table, the skateboard can drive the dial indicator to slide up and down along the outer surface of the guide post. At the same time, the driving motor drives the driving wheel, and the driving wheel drives the driven wheels, so that the guide post rotates in the same direction as the driven wheels on the top of the support disc through the connecting rod. On the one hand, the inspected part of the flange can be adjusted; on the other hand, it is convenient to automatically adjust the guide post and its connection structure on the top of the support disc, thereby improving the inspection speed of the flange.

[0010] Preferably, guide rods are additionally arranged on both sides of the central position in the inner cavity of the inspection table, and the outer ends of the guide rods penetrate through the inner wall of the inspection table and extend outwards. The guide rods can move along the inspection table.

[0011] Preferably, a fixed cone head is installed at the inner end of the guide rod, and a return spring is sleeved on the surface of the guide rod. The two ends of the return spring are respectively in contact with the inner wall of the inspection table and the fixed cone head. After the flange is placed at the center of the top of the inspection table, the guide rod drives the fixed cone head to closely fit the surface of the flange under the action of the return spring. On the one hand, it can inspect various flanges within a certain range; on the other hand, it can fix the flange and ensure the stability of the flange inspection, thereby avoiding the phenomenon of flange shaking and incorrect detection data.

[0012] Preferably, a rotating head is rotatably connected to the central position at the top of the guide post, and sliding grooves are vertically formed at the center positions on the front and back of the guide post. It can drive the rotating head to rotate on the top of the guide post and adjust the rotation direction of the rotating head.

[0013] Preferably, a threaded lead screw is vertically additionally arranged at the central position in the inner cavity of the guide post and is coaxially connected with the rotating head. A sliding block is sleeved on the upper part of the surface of the threaded lead screw and is connected to the skateboard through the sliding groove. The rotating head drives the threaded lead screw to rotate on the guide post, and the sliding block drives the skateboard to slide up and down along the sliding groove according to the rotation direction of the threaded lead screw, thereby ensuring the stability of the sliding block and the dial indicator on the guide post.

[0014] Preferably, the driving wheel and the driven wheels are rotatably connected to the bottom of the support disc, and support columns are additionally arranged on both sides of the bottom of the annular toothed plate. When the driving wheel and the driven wheels rotate, they will not drive the support disc to rotate, and the annular toothed plate can rotate on the support columns, ensuring the stability of the annular toothed plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] For the inspection device for various flanges, by placing the flange at the center of the top of the inspection table, the sliding plate can drive the dial indicator to slide up and down along the outer surface of the guide post, so as to adjust the inspected part of the flange. At the same time, the driving motor drives the driving wheel, and the driving wheel drives the driven wheel, so that the guide post rotates in the same direction as the driven wheel on the top of the supporting disc through the connecting rod. It is convenient to automatically adjust the guide post and its connection structure on the top of the supporting disc, thereby improving the inspection speed of the flange.
