Description

Technical Field

[0001] The utility model belongs to the technical field related to marking tools, and in particular relates to a tool for marking right-angle lines on corbels installed on round tubes. Background Art

[0002] A round tube is a steel material with open ends and a hollow concentric cross-section, and a large length-to-circumference ratio. It can be used in pipelines, thermal equipment, machinery, petroleum and geological drilling, containers, the chemical industry, and special purposes. During the use of round tubes, in order to enhance the structural stability and safety of the round tubes, corbels are usually installed on the outer diameter of the round tube. The corbels serve as the transition between the beam and the supporting structure, effectively transferring the load on the beam to the supporting structure, ensuring the stability and safety of the entire structure. When installing the corbels, a notch structure that matches the corbel needs to be cut on the outer wall of the round tube. Before cutting the notch, it is necessary to mark the line to determine the cutting position and size. Currently, marking of round tubes is mostly based on the workers' experience. The radial line of the round tube is prone to deviation during marking, resulting in large marking errors and low efficiency.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, a tool for drawing right-angle lines on round tube corbels is provided, the marking tool body 1, the marking tool body 1 is a semicircular arc structure, the marking tool body 1 includes a first tool plate 3 and a second tool plate 4, the two end positions of the first tool plate 3 and the second tool plate 4 are connected by an end connecting plate 7, the middle position of the first tool plate 3 and the second tool plate 4 is connected by a middle reinforcing rib 8, a scale line 1 5 is provided on the outer curved surface of the first tool plate 3, and a scale line 2 6 is provided on the outer curved surface of the second tool plate 4, and a handle 2 is fixedly provided near the middle position on the outer side of the first tool plate 3 and the second tool plate 4 for easy picking up of the marking tool body 1.

[0023] The marking tool body 1 is provided with different arc radius sizes, and the inner diameter size of the marking tool body 1 matches the outer diameter size of the circular tube to be marked. For marking circular tubes of different diameters, the marking tool body 1 of corresponding specifications is selected.

[0024] The handle 2 is a U-shaped structure, and the handle 2 and the middle reinforcement rib 8 form a certain angle in the range of 25°-30°. Holding the handle 2 with the left hand and drawing with the right hand makes the operation smoother.

[0025] Scale line 1 5 is an angle line, scale line 2 6 is an arc length line, and the zero points of scale line 1 5 and scale line 2 6 are both the center position of the marking tool body 1 to facilitate intuitive reading.

[0026] A hollow structure is formed between the first tool plate 3 and the second tool plate 4 at both sides of the middle reinforcing rib 8 to effectively reduce the weight of the marking tool body 1 .

[0027] The four corners at both ends of the marking tool body 1 are polished into rounded structures to avoid collisions with sharp corners.

[0028] The working principle of the utility model is as follows: when the main body 1 of the marking tool is manufactured, the metal strip is bent into the required arc specifications, and then the end connecting plate 7 and the middle reinforcing rib 8 are welded and fixed to the first tool plate 3 and the second tool plate 4 respectively. After welding, the shape is corrected, and then the handle 2 is welded to the outside of the first tool plate 3 and the second tool plate 4 by using a cold welding machine. The use of the cold welding machine can effectively reduce the deformation of the first tool plate 3 and the second tool plate 4 during the welding process. The outside of the end connecting plate 7 of the marking tool main body 1 can be marked to clearly indicate the size specifications of the marking round tube corresponding to the tool. The utility model has a simple structure and low manufacturing cost.

[0029] When using the marking tool body 1, first, according to the position of the horn installation, use a ruler to measure and mark the position of the length direction of the circular tube. Then, one side of the marking tool body 1 is attached to the marked position in the length direction. Since the inner diameter of the marking tool body 1 matches the outer diameter of the circular tube, the marking tool body 1 will not tilt relative to the circular tube, thereby effectively ensuring the marking accuracy and reducing the difficulty of marking. The setting of the scale line 1 5 and the scale line 2 6 can effectively control the arc length and angle of the marking.

[0030] At the same time, by observing the fit between the marking tool body 1 and the round tube, it can also be used as a detection tool to detect whether the size specifications of the round tube meet the standards; the marking tool body 1 of the utility model is designed with a semi-circular arc structure, and the size specifications are adapted to the outer diameter of the round tube, and has a good fit with the outer wall of the round tube. By using the two sides of the marking tool body 1 as a comparison ruler, the radial marking accuracy of the round tube can be effectively guaranteed to avoid deflection. At the same time, scale lines are provided on both sides of the marking tool body 1, which can meet the marking requirements such as marking length and angle. The marking tool body 1 is designed with a hollow structure, which effectively reduces its own weight and is provided with a handle 2 for easy picking and use. Using this tool can effectively reduce the difficulty of marking the round tube assembly corbel and improve the marking efficiency.

[0031] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
