Description

Technical Field

[0001] The present application relates to the technical field of roadbed construction, and more specifically, to a tool for quickly marking grid lines for roadbed construction. Background Art

[0002] During roadbed construction, lime is needed to mark out grid lines for positioning, which are used for positioning and scope limitation of subsequent construction.

[0003] The prior art document with publication number CN220704269U provides a roadbed construction grid line rapid marking tool, including a transmission box, a connecting shaft is rotatably connected to the center of the inner wall of the transmission box, and a distance measuring roller is fixedly connected to one end of the connecting shaft.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] 1. If it needs to be pushed manually, the roller's walking path cannot be guaranteed to remain straight, and the final sliding line will deteriorate;

[0006] 2. There is a fixed angle between the grid rows and columns. If the grid is a rectangle, the rows and columns must be kept vertical. If it is other rhombuses or quadrilaterals, the row and column lines need to be adjusted in angle. It is difficult to keep the grid shape the same as set by manually pushing the roller to draw lines.

[0007] Regarding the above-mentioned related technologies, the inventor believes that if it needs to be pushed manually, then there is no way to ensure that the walking path of the roller remains straight, and the final sliding line will be deteriorated. There is a fixed angle between the grid rows and columns. If the grid is a rectangle, then the row and column lines must remain vertical. If it is other rhombuses or flat quadrilaterals, then the row and column lines need to adjust the angle. It is difficult to keep the grid shape the same as the setting by manually pushing the roller to draw the lines.

[0008] In view of this, we propose a tool for fast grid line marking in roadbed construction. Utility Model Content

[0009] 1. Technical issues to be solved

[0010] The purpose of the present application is to provide a tool for rapid grid line marking in roadbed construction, which solves the technical problem in the above-mentioned background technology that it needs to be pushed manually, and the walking path of the roller cannot be guaranteed to remain straight, and the line that finally slides out is deteriorated. There is a fixed angle between the grid rows and columns of the grid lines. If the grid is a rectangle, the row and column markings must be kept vertical. If it is other rhombuses or flat quadrilaterals, the row and column markings need to adjust the angle. It is difficult to keep the grid shape the same as the setting when the roller is directly pushed manually to mark the lines, thereby achieving a technical effect.
