Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of elbow production line equipment, and particularly relates to an elbow parameter measuring device and method. BACKGROUND

[0002] In oil and gas pipeline and chemical industry projects, elbows are widely used. By using elbows, the setting direction of the pipeline can be changed, so as to change the moving direction of the flowing medium. The specification parameters of the elbow are crucial to the use of the elbow. If the specification parameters do not meet the requirements, the installation quality of the elbow will be affected, thereby causing installation errors.

[0003] The existing elbow generally uses a special size measuring instrument in combination with a displacement or laser sensor to perform parameter measurement work. In the parameter measurement work of the elbow, the distance from the center of one end of the elbow to the end face of the other end is one of the key parameters to be measured. Although the displacement or laser sensor can determine the center position of the elbow by measuring the boundary position of the elbow, the displacement or laser sensor used needs to be adjusted for each elbow during measurement, which results in a slow measurement speed and makes it difficult to match the production speed of the elbow production line, thereby affecting the production efficiency of the elbow. At the same time, although the specification parameters of the elbow need to be controlled during production, measuring by using a high-precision displacement or laser sensor is also a case of not worth the candle.

[0004] Therefore, the existing elbow specification parameter measurement efficiency is low. SUMMARY

[0042] In order to make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0043] REFERENCE Figure 1The application provides a bend parameter measuring device, which comprises a limiting part 100 and a conversion part 200. The limiting part 100 is provided with a first abutting surface and a second abutting surface for placing a bend. The first abutting surface can abut against one end surface of the bend, and the second abutting surface can abut against the other end surface of the bend. The second abutting surface is provided with a sensing and measuring surface for abutting against the bend, and the sensing and measuring surface can measure the position information of the end surface of the bend away from the first abutting surface. The conversion part 200 is connected with the sensing and measuring surface, and the conversion part 200 can obtain the distance information between the center of the end of the bend away from the first abutting surface and the other end surface of the bend based on the measured position information of the end of the bend away from the first abutting surface.

[0044] Specifically, referring to Figure 2 The first abutting surface and the second abutting surface of the limiting part 100 are perpendicular to each other, so that an included angle is formed between the first abutting surface and the second abutting surface. The bend to be measured is placed in the included angle formed by the first abutting surface and the second abutting surface, so that the one end surface of the bend abuts against the first abutting surface, and the other end surface of the bend abuts against the second abutting surface. The second abutting surface is provided with a sensing and measuring surface, so that the second abutting surface abuts against the end surface of the bend away from the first abutting surface through the sensing and measuring surface. The abutting position of the end surface of the bend close to the first abutting surface can be determined through the first abutting surface. Since the end surface of the bend close to the first abutting surface abuts against the first abutting surface, the position of the first abutting surface is the position of the end surface of the bend close to the first abutting surface. The position information of the end surface of the bend away from the first abutting surface can be measured and determined through the sensing and measuring surface. The signal output end of the sensing and measuring surface is connected with the signal input end of the conversion part 200, so that the position information of the end surface of the bend away from the first abutting surface measured and determined by the sensing and measuring surface can be transmitted to the conversion part 200. The conversion part 200 can obtain the distance information between the center of the end of the bend away from the first abutting surface and the first abutting surface according to the measured and determined position information of the end of the bend away from the first abutting surface. Since the position of the first abutting surface is the position of the end surface of the bend close to the first abutting surface, the distance information between the center of the end of the bend away from the first abutting surface and the end surface of the bend close to the first abutting surface can be determined. The bend can be quickly measured in specification parameters only by placing the bend between the first abutting surface and the second abutting surface of the limiting part 100, which replaces the original measurement mode of adjusting displacement or laser sensor in a targeted manner, improves the measurement efficiency of the bend, matches the production speed of the bend production line, and improves the production efficiency of the bend.

[0045] In some specific embodiments of the application, referring to Figure 1The limiting part 100 comprises a first plate body 110 and a second plate body 120. One side of the first plate body 110 forms a first abutting surface. One side of the second plate body 120 forms a second abutting surface. The first plate body 110 is arranged perpendicularly to the second plate body 120 on one side in the length direction of the second abutting surface, so that an included angle can be formed between the first abutting surface and the second abutting surface, and a sensing measurement surface is arranged on the other side in the length direction of the second abutting surface, so that the first abutting surface and the sensing measurement surface can abut the two ends of the elbow respectively. The second plate body 120 is arranged horizontally, so that the elbow can be placed on the second abutting surface, the end face of the elbow away from the first abutting surface can abut the sensing measurement surface, and the end face of the elbow close to the first abutting surface can abut the first abutting surface. The intersection of the first abutting surface and the second abutting surface is the position of the first abutting surface, and is also the position of the end face of the elbow close to the first abutting surface. At the same time, the position information of the end face of the elbow away from the first abutting surface can be determined by the sensing measurement surface on the second abutting surface, and the distance between the center of the end of the elbow away from the first abutting surface and the first abutting surface, i.e. the end face of the elbow close to the first abutting surface, can be quickly obtained by the conversion part 200. The structure is flexible and simple, and is convenient for use and measurement.

[0046] In some embodiments of the application, reference is made to Figure 1 The second plate body 120 is provided with a pressure sensing assembly 121, and the bearing side of the pressure sensing assembly 121 forms a sensing measurement surface. The pressure sensing assembly 121 can obtain the boundary position information of the end face of the elbow away from the first abutting surface according to the pressure condition of the bearing side.

[0047] Specifically, the pressure sensing assembly 121 is arranged on the second abutting surface of the second plate body 120, and a sensing measurement surface is formed by a load-bearing side of the pressure sensing assembly 121 for bearing external objects. By placing the elbow between the first abutting surface and the load-bearing side of the pressure sensing assembly 121, one end face of the elbow abuts against the load-bearing side of the pressure sensing assembly 121, and the other end abuts against the first abutting surface. Since the second plate body 120 is horizontally placed, under the action of the gravity of the elbow itself, the load-bearing side of the pressure sensing assembly 121 on the second plate body 120 can be pressed, and the pressure sensing assembly 121 can measure the boundary position information of the one end face of the elbow away from the first abutting surface by the area range of the pressure applied to the load-bearing side by the one end face of the elbow away from the first abutting surface. Thus, the position information of the one end face of the elbow away from the first abutting surface on the second plate body 120 is determined, so as to subsequently obtain the position information of the center of the one end of the elbow away from the first abutting surface on the second plate body 120 through the position information of the one end face of the elbow away from the first abutting surface on the second plate body 120, and thus the distance between the center of the one end of the elbow away from the first abutting surface and the one end face of the elbow close to the first abutting surface is determined. Only by placing the elbow on the load-bearing side of the pressure sensing assembly 121, the specification parameters of the elbow can be quickly measured, which replaces the original measurement mode of adjusting the displacement or laser sensor in a targeted manner, improves the measurement efficiency of the elbow, and makes it possible to match the production speed of the elbow production line, thereby improving the production efficiency of the elbow.

[0048] In some embodiments of the present application, with reference to Figure 2 The pressure sensing assembly 121 comprises a sensing unit 1211. The sensing unit 1211 is in a plurality, and the plurality of sensing units 1211 are arranged in an array, and the side sides between every two adjacent sensing units 1211 abut against each other, so that the plurality of sensing units 1211 can bear the elbow. When any sensing unit 1211 is pressed, the corresponding boundary position information of the one end face of the elbow away from the first abutting surface can be obtained.

[0049] Specifically, the plurality of sensing units 1211 are arranged in an array to form a plurality of rows and columns of sensing units 1211, and the side sides between every two adjacent sensing units 1211 abut against each other, so that the plurality of rows and columns of sensing units 1211 form a sensing measurement surface. When the elbow is placed on the sensing measurement surface and abuts against the one end of the elbow away from the first abutting surface, the one end face of the placed elbow away from the first abutting surface will be pressed on the corresponding sensing unit 1211 according to the shape of the end face opening, so that the boundary position information of the one end face of the elbow away from the first abutting surface on the second plate body 120 can be determined according to the position of the sensing unit 1211 pressed thereon, so as to subsequently convert and determine the position information of the center of the one end of the elbow away from the first abutting surface on the second plate body 120.

[0050] Further, the sensing unit 1211 is a square structure of 0.1 mm x 0.1 mm, so that the area S of the sensing unit 1211 is 0.01 mm 2 , facilitating arrangement and combination of multiple sensing units 1211 and formation of a sensing measurement surface.

[0051] After the elbow is placed, the pressure of the multiple sensing units 1211 in contact with the elbow is obtained according to the following formula:

[0052]

[0053] Simplify as:

[0054]

[0055] Wherein, G is the weight of the elbow, D is the outer diameter of the elbow, t is the outer wall thickness of the elbow, and thus D-2t is the inner diameter of the elbow.

[0056] The pressure of a single sensing unit 1211 in contact with the elbow is obtained according to the following formula:

[0057] F = P x S

[0058] Wherein, F is the pressure of a single sensing unit 1211 in contact with the elbow, S is the area of a single sensing unit 1211, and P is the pressure of the multiple sensing units 1211 in contact with the elbow, and thus:

[0059]

[0060] After each sensing unit 1211 in contact with the elbow receives the pressure F, it will respectively convert to generate an electrical signal for identifying the position of the sensing unit 1211, so that the number of each sensing unit 1211 in contact with the elbow can be obtained according to the multiple sensing units 1211 arranged in the form of multiple rows and multiple columns.

[0061] For example, referring to Figure 3 The column number of the sensing unit 1211 in the multiple sensing units 1211 in contact with the elbow closest to the first abutting surface is i, and the column number of the sensing unit 1211 in the multiple sensing units 1211 in contact with the elbow farthest from the first abutting surface is j.

[0062] In some embodiments of the present application, the pressure sensing assembly 121 is embedded on the second plate body 120, and each sensing unit 1211 is at the same horizontal height as the second abutting surface of the second plate body 120, so that the sensing measurement surface formed by the multiple sensing units 1211 can be at the same horizontal height as the second abutting surface, thereby ensuring measurement accuracy.

[0063] In some embodiments of the present application, with reference to Figure 2 The conversion unit 200 comprises a data processing unit 210. The data processing unit 210 is electrically connected with the pressure sensing assembly 121, and thus the data processing unit 210 is electrically connected with each sensing unit 1211. The data processing unit 210 can receive the boundary position information of the end surface of the elbow away from the first abutting surface according to the position of the sensing unit 1211 under pressure, and further obtain the position information of the center of the end of the elbow away from the first abutting surface. Further, the data processing unit 210 can further obtain the distance information between the center of the end of the elbow away from the first abutting surface and the other end surface of the elbow according to the position information of the center of the end of the elbow away from the first abutting surface.

[0064] With reference to Figure 3 The distance between the center of the end of the elbow away from the first abutting surface and the other end surface of the elbow can be obtained according to the following formula:

[0065] c = b + a

[0066] Wherein, c is the distance between the center of the end of the elbow away from the first abutting surface and the other end surface of the elbow, b is the distance between the center of the end of the elbow away from the first abutting surface and the sensing unit 1211 closest to the first abutting surface among all the sensing units 1211, and a is the distance between the sensing unit 1211 closest to the first abutting surface among all the sensing units 1211 and the first abutting surface.

[0067] It should be noted that the distance between the sensing unit 1211 closest to the first abutting surface among all the sensing units 1211 and the first abutting surface is a preset value.

[0068] The distance between the center of the end of the elbow away from the first abutting surface and the sensing unit 1211 closest to the first abutting surface among all the sensing units 1211 can be obtained according to the following formula:

[0069]

[0070] Simplify as:

[0071]

[0072] Wherein, b is the distance between the center of the end of the elbow away from the first abutting surface and the sensing unit 1211 closest to the first abutting surface among all the sensing units 1211, j is the column number of the sensing unit 1211 farthest from the first abutting surface among the multiple sensing units 1211 in contact with the elbow, and i is the column number of the sensing unit 1211 closest to the first abutting surface among the multiple sensing units 1211 in contact with the elbow.

[0073] Therefore, the distance between the center of the one end of the elbow away from the first abutting surface and the other end surface of the elbow can be obtained according to the following formula:

[0074]

[0075] In some embodiments of the present application, with reference to Figure 2 The conversion part 200 further comprises a display assembly 220. The display assembly 220 is electrically connected with the data processing unit 210, so that the distance information between the center of the one end of the elbow away from the first abutting surface and the other end surface of the elbow generated by the data processing unit 210 can be directly displayed through the display assembly 220, facilitating observation and improving the measurement speed.

[0076] In some embodiments of the present application, with reference to Figure 2 The data processing unit 210 is embedded in the second plate body 120. The display assembly 220 is embedded in the first plate body 110, and the display side of the display assembly 220 for displaying the distance information between the center of the one end of the elbow away from the first abutting surface and the other end surface of the elbow is exposed on the side of the first plate body 110 away from the first abutting surface, facilitating observation and improving the measurement speed.

[0077] Further, a power supply is arranged in the electric circuit composed of the display assembly 220, the data processing unit 210 and the pressure sensing assembly 121, and can supply power to the display assembly 220, the data processing unit 210 and the pressure sensing assembly 121. Moreover, the power supply is embedded in the first plate body 110, and the switch side of the power supply is exposed on the side of the first plate body 110 away from the first abutting surface, facilitating control of power supply to the display assembly 220, the data processing unit 210 and the pressure sensing assembly 121 and improving the measurement speed.

[0078] In some embodiments of the present application, with reference to Figure 2 A level 122 is arranged on the second abutting surface, and the level 122 can be observed to determine whether the second plate body 120 is in a horizontal direction, thereby ensuring the accuracy of subsequent measurement.

[0079] The application further provides a bend parameter measurement method, which adopts the bend parameter measurement device in any one of the above embodiments and comprises the following steps: one end of the bend is placed on the second abutting surface of the limiting portion 100 and abuts against the sensing measurement surface on the second abutting surface, and the other end of the bend abuts against the first abutting surface of the limiting portion 100. The position information of the end face of the end of the bend away from the first abutting surface is measured by the sensing measurement surface and transmitted to the conversion portion 200. The conversion portion 200 obtains the distance information between the center of the end of the bend away from the first abutting surface and the other end face of the bend based on the position information of the end of the bend away from the first abutting surface. The placement position of the bend is changed, and the above steps are repeated. Another bend is replaced, and the above steps are repeated.

[0080] Specifically, one end of the bend is placed on the second abutting surface of the second plate body 120 and abuts against the sensing measurement surface on the second abutting surface, and the other end of the bend abuts against the first abutting surface of the first plate body 110. Under the action of gravity of the bend, the end face of the end of the bend away from the first abutting surface is pressed on the part of the sensing unit 1211. The number of the sensing unit 1211 under pressure is determined through the feedback of the sensing unit 1211, so that the boundary position of the end face of the end of the bend away from the first abutting surface is determined and transmitted to the data processing unit 210. The data processing unit 210 obtains the distance between the center of the end of the bend away from the first abutting surface and the first abutting surface based on the boundary position of the end face of the end of the bend away from the first abutting surface. Since the position of the first abutting surface is the position of the end face of the end of the bend close to the first abutting surface, the distance between the center of the end of the bend away from the first abutting surface and the other end face of the bend can be obtained and transmitted to the display assembly 220 for reading and recording the value by the staff. The placement position of the bend is changed, and the distance between the center of the end of the bend away from the first abutting surface and the other end face of the bend is measured again and read and recorded. The multiple measurement results obtained for the distance between the center of the end of the bend away from the first abutting surface and the other end face of the bend are averaged, so that the accuracy of the measurement result is ensured. Another bend is replaced, and the above steps are repeated. Only by placing the bend on the sensing measurement surface, the specification parameters of the bend can be quickly measured, the same bend can be measured multiple times quickly, or multiple bends can be measured in turn quickly, which replaces the original measurement mode of adjusting displacement or laser sensor in a targeted manner, improves the measurement efficiency of the bend, matches the production speed of the bend production line, and improves the production efficiency of the bend.
