[0025] The following is combined with Figure 1-2 This application is described in further detail.
[0026] An embodiment of the present application discloses a pipeline opening and marking tool.
[0027] refer to Figure 1 , the pipeline opening and marking tool includes a magnetic plate 1, a main block 2, a column 21, a cross bar 3, an adjustment rod 31 and a circular laser light 4. The bottom of the magnetic plate 1 is an arc-shaped depression, which is used to be attracted and fixed to the pipeline. Bandages 11 are also provided on both sides of the bottom of the magnetic plate 1 for tying to the pipeline. The main block 2 is fixed on the top of the magnetic plate 1, and the column 21 is fixed in the middle position of the upper surface of the main block 2. The cross bar 3 is slidably connected to the column 21, and the length direction is parallel to the axis of the pipeline. The top of the column 21 is threadedly connected with a positioning screw 22, and the positioning screw 22 is tightened against the cross bar 3. The adjusting rod 31 is vertically arranged, vertically sliding at one end of the cross bar 3, and a counterweight is provided at the other end of the cross bar 3. The circular laser light 4 is installed at the bottom of the adjusting rod 31, and can project a circular projection on the pipeline. The adjusting rod 31 can be fixed in position with the cross bar 3.
[0028] The magnetic plate 1 is adsorbed on the pipeline. When the pipeline is too large or too small, it is fixed to the pipeline by the binding 11. After adjusting the position of the cross bar 3, the position of the cross bar 3 is fixed by the positioning bolt. Finally, the circular laser light 4 is turned on, and the position of the adjustment rod 31 is adjusted. The size of the circular projection projected on the pipeline is adjusted by adjusting the distance between the circular laser light 4 and the pipeline. Then, the pipeline can be marked or directly cut according to the projection contour, which effectively improves the efficiency of pipeline opening and marking.
[0029] refer to Figure 2 , the adjusting rod 31 is provided with a fixing clamp 32, which can clamp and fix the adjusting rod 31. A plurality of convex rings 311 are evenly distributed on the circumferential outer wall of the adjusting rod 31. A plurality of horizontally arranged convex strips 321 are vertically and evenly distributed on the clamping surface of the fixing clamp 32. An adjusting wheel 33 is rotatably connected to the end of the cross bar 3 close to the adjusting rod 31, and the rotation axis of the adjusting wheel 33 is horizontally arranged. The circumferential outer wall of the adjusting wheel 33 is made of rubber material and can be tightly pressed against the adjusting rod 31. Convex patterns 331 are evenly distributed on the circumferential outer wall of the adjusting wheel 33. The spacing between the convex patterns 331, the convex strips 321 and the convex rings 311 is the same. After the fixing clamp 32 is opened, the adjusting rod 31 will not slide downward.
[0030] When adjusting the position of the adjusting rod 31, the fixing clamp 32 is opened, and then the adjusting wheel 33 is rotated. The adjusting rod 31 is driven to slide through the abutment relationship between the adjusting wheel 33 and the adjusting rod 31, and the position of the adjusting rod 31 is finely adjusted. After the position of the adjusting rod 31 is adjusted, it is clamped and fixed by the fixing clamp 32, thereby improving the stability of the position adjustment of the adjusting rod 31. The arrangement of the convex pattern 331, the convex strip 321 and the convex ring 311 can effectively achieve mutual engagement, thereby improving the position adjustment and accuracy of the adjusting rod 31 and the firmness of the fixation after the position adjustment.
[0031] The implementation principle of the pipeline hole marking tool of the embodiment of the present application is as follows: after the magnetic plate 1 is adsorbed and fixed to the pipeline, the circular laser light 4 is turned on, the position of the crossbar 3 is adjusted, and then the fixing clamp 32 is opened, and the position of the adjusting rod 31 is adjusted by rotating the adjusting wheel 33, and finally the position of the adjusting rod 31 is fixed by the fixing clamp 32, and then the circular projection is projected onto the pipeline by the circular laser light 4, and then the projection is traced to mark or directly make a hole. The efficiency of pipeline hole marking is effectively improved, and the efficiency and accuracy of adjusting the size of pipeline hole marking are also improved.
[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
