Description

Technical Field

[0001] The utility model relates to the technical field of land space planning, and specifically refers to a land space planning line-laying device. Background Art

[0002] Land is an important foundation for our survival and development. Therefore, it is of great significance to do a good job in land surveying. The value of land consolidation work is also constantly increasing. Therefore, people’s requirements for surveying and mapping technology in land surveying are also constantly increasing. Reasonable spatial planning of the country is inseparable from accurate land measurement. In the process of national space planning, line-laying devices are often used to use them for national space planning.

[0003] The conventional pay-off device used in land and space planning mainly consists of a pay-off reel, a trolley and casters. When in use, the casters are moved in the measurement area by pushing the trolley, and then the handwheel is turned to drive the pay-off reel to rotate to perform the pay-off operation, completing the entire pay-off process. For example, the "A pay-off device for land and space planning" disclosed in patent publication number CN221253497U rotates the rotating block, the rotating plate and the rotating shaft, and the vortex spring is forced to shrink, which can pull out the wire body, and limit the contact between the wedge block B and the wedge block A, and fix the length of the wire body pulled out. When the wire body needs to be reeled in, the slide bar can be pulled upward, the wedge block B is disengaged from the wedge block A, and the limit of the rotating block, the rotating plate and the rotating shaft is released, so that the vortex spring stretches due to its own elastic force and drives it to rotate in the opposite direction, and the wire body can be automatically reeled in and arranged on the outer wall of the rotating block, without the need for the operator to manually reel it in, which is more convenient and quick.

[0004] However, the above structure still has certain defects: the above pay-off frame cannot be installed and used for rollers of different models, has poor versatility, and has no guiding function for the measuring line, so that the position of the measuring line keeps changing along the roller when paying out.
