Abstract
Description
Technical Field
[0001] The invention relates to a measuring tool for the misalignment of square tubes of a lashing bridge, and belongs to the technical field of measuring the lateral displacement of square tubes. Background Art
[0002] There are many lashing bridges on the hatch enclosure of container ships. The lashing bridges are made of many vertical square tubes connected with horizontal platforms. In the manufacturing process, the free ends of the square tubes are easily misaligned due to the influence of welding stress. According to the size of the misalignment, it is determined whether welding or plate pasting is needed to meet the structural alignment strength. The present invention improves the measurement accuracy by more accurately measuring the misalignment of the square tubes.
[0003] The container ship lashing bridge is erected on the hatch coaming. The lower end of the square tube of the lashing bridge contacts the hatch coaming top plate. Each square tube has strict alignment accuracy requirements with the back of the top plate. If the tolerance range is exceeded, the back of the top plate needs to be welded or plated. In order to prevent safety problems such as tipping over after the lashing bridge is loaded, the lower end of the square tube will be sealed and welded. The interference of the weld bead increases the cumulative error in the measurement alignment process. The existing operation method cannot guarantee the measurement accuracy. Special tools are studied and produced to provide operators with a simple and fast operation method to meet the operation needs under complex conditions. Summary of the invention
[0004] In order to solve the problems existing in the prior art, the present invention provides a measuring tool for the misalignment of square pipes of a binding bridge, which can avoid the weld and accurately measure, thereby improving the operation accuracy.
[0005] The technical solution adopted by the present invention is: a measuring tool for the misalignment of a square pipe of a tying bridge, the tool comprising a first straight edge section, a second straight edge section and a bevel edge section, the first straight edge section and the second straight edge section are perpendicular to each other; an inner concave arc is arranged at the intersection of the first straight edge section and the second straight edge section, and the radius of the inner concave arc is greater than the diameter of the weld bead;
[0006] A first straight edge scale is set on the first straight edge segment, a second straight edge scale is set on the second straight edge segment, and a hypotenuse scale is set on the hypotenuse segment; the vertical point on the first straight edge scale perpendicular to the second straight edge segment is used as the zero point, and the zero point of the second straight edge scale is the vertical point perpendicular to the first straight edge segment;
[0007] The first straight edge segment and the second straight edge segment act on the top plate and the square tube respectively to determine whether the top plate and the square tube are perpendicular;
[0008] Apply the first straight edge segment vertically to the top plate, and use the second straight edge scale to measure the distance from the top plate to the square tube inspection line.
[0009] The length of the first straight side segment is equal to or unequal to the length of the second straight side segment.
[0010] Compared with the prior art, the present invention has the following advantages: the tool comprises a first straight edge section, a second straight edge section and a bevel edge section, the first straight edge section and the second straight edge section are perpendicular to each other; and an inner concave arc is arranged at the intersection of the first straight edge section and the second straight edge section, and the radius of the inner concave arc is greater than the diameter of the weld. The tool is suitable for measuring the alignment deviation data of square tubes of any container lashing bridge. Compared with the prior art, the tool reduces the difficulty of operation, improves the operation efficiency and operation accuracy, improves the convenience of personnel operation, and prevents inaccurate data and large errors caused by measurement cumulative errors, thereby increasing the welding and plate pasting rate and generating unnecessary waste.

DETAILED DESCRIPTION
[0015] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0018] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0019] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0020] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0021] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0022] Figure 1 and Figure 2 A measuring tool for the misalignment of square pipes for tying bridges is shown. The tool comprises a first straight edge section 1, a second straight edge section 2 and a bevel edge section 3. The first straight edge section 1 and the second straight edge section 2 are perpendicular to each other.
[0023] An inner concave arc 7 is arranged at the intersection of the first straight edge segment 1 and the second straight edge segment 2, and the radius of the inner concave arc 7 is greater than the diameter of the weld bead 9; a first straight edge scale 4 is arranged on the first straight edge segment 1, a second straight edge scale 5 is arranged on the second straight edge segment 2, and a bevel edge scale 6 is arranged on the bevel edge segment 3; the vertical point on the first straight edge scale 4 perpendicular to the second straight edge segment 2 is taken as the zero point, and the zero point of the second straight edge scale 5 is the vertical point perpendicular to the first straight edge segment 1.
[0024] In some specific embodiments, the length of the first straight edge segment 1 is equal to the length of the second straight edge segment 2 .
[0025] In some specific embodiments, the length of the first straight edge segment 1 is not equal to the length of the second straight edge segment 2 .
[0026] When the above technical solution is used, the first straight edge section 1 and the second straight edge section 2 are applied to the top plate 8 and the square tube 10 respectively, the first straight edge section 1 is perpendicular to the top plate 8, the inner concave arc 7 covers the outside of the weld 9, and the tool is pushed in the direction of the square tube 10 until the second straight edge section 2 acts on the square tube 10, and it is checked whether the second straight edge section 2 is attached to the square tube 10, and then it is judged whether the top plate 8 and the square tube 10 are perpendicular. If it is completely attached to the square tube 10, the top plate 8 and the square tube 10 are perpendicular to each other. If the end point of the inner concave arc 7 contacts the square tube 10, and the end point of the second straight edge section 2 does not contact the square tube 10, the angle between the square tube 10 and the top plate 8 is greater than 90 degrees; if the end point of the inner concave arc 7 does not contact the square tube 10, and the end point of the second straight edge section 2 contacts the square tube 10, the angle between the square tube 10 and the top plate 8 is less than 90 degrees. That is, when the square tube 10 is not perpendicular to the top plate 8, the inclination direction of the square tube 10 can be judged.
[0027] In addition, the first straight edge 1 is applied vertically to the top plate 8, and the distance from the top plate 8 to the square tube inspection line 11 is measured with the second straight edge scale 5. The distance between the inspection line on the square tube wall and the inspection line on the top plate in the horizontal and vertical directions is measured with a measuring tool. When measuring the vertical distance, ensure that the tool is perpendicular to the top plate plane to reduce the measurement error. The design of the inner concave arc avoids the weld bead for more accurate measurement and improves the operation accuracy.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
