Description

Technical Field

[0001] The invention relates to the technical field of line-setting devices, and in particular to a line-setting device for surveying and mapping engineering. Background Art

[0002] Engineering surveying and mapping includes various surveying work carried out in the survey, design, construction and management stages of engineering construction. During the construction of a building project, it is necessary to perform a wire laying operation to check the positioning of the building project, thereby improving the accuracy of the positioning of the building project. During the winding process of the wire laying device currently on the market, since there is no component inside the wire laying device to arrange the rope body evenly, it is easy for the rope body to continue to wrap around one side of the winding roller, causing the rope body to deviate from the winding roller and wrap around the rotating shaft, causing the wire laying device to malfunction and fail to lay the wire.

[0003] To this end, those skilled in the art have conducted research and improvements, such as a wire-laying device for engineering surveying and mapping with application number 202021185020.8. In this technical solution, when the screw is rotated, the ball nut above moves left and right, which is conducive to making the wire in the wire tube evenly arranged and wound on the winding roller. However, this technical solution still has many defects:

[0004] 1) The device uses a motor as a power mechanism, which increases the equipment cost;

[0005] 2) The device can only measure in a single direction when in use, which is highly limited;

[0006] 3) The device cannot ensure that the wire rope is in a straight state when it is rolled up, which is not conducive to keeping the wire neat when it is rolled up.
