Pay-off device for territorial space planning and use method thereof

Abstract

The invention relates to a pay-off device for territorial space planning, which comprises a vehicle body, shaft seats are mounted on the periphery of the bottom side of the vehicle body, rotating shafts are mounted between the shaft seats, first chain wheels are mounted at two ends of each rotating shaft, limiting columns are mounted on the periphery of the top side of the vehicle body, and a plurality of guide rods are mounted between the limiting columns on the same side. The guide rod is sleeved with a first spring, and the first spring is connected with the sliding base and the limiting column away from the end of the supporting arm. During movement, rotation of the wire wheel is achieved through movement of the vehicle body so that winding and unwinding of the measuring wire can be automatically achieved, meanwhile, separation of the inserting rod and the inserting groove is achieved through rotation of the threaded rod, when the vehicle body moves, the wire wheel is kept still, the first rotating handle drives the connecting shaft and the wire wheel to rotate so that winding and unwinding of the measuring wire can be achieved, and the measuring wire can be adjusted conveniently; and practical operation and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of land space planning, in particular to a wire releasing device for land space planning and a usage method thereof. Background technique [0002] National Plan for Main Functional Areas This is China's first land space development plan, and it is a strategic, basic, and restrictive plan; in land space planning, the land measurement device is very important, and the line device is used Retracting and unwinding of the measuring rope during measurement. [0003] The existing pay-off device realizes the retraction and release of the measuring rope by manually rotating the wire wheel, which requires the cooperation of multiple people. This operation method is labor-intensive and inconvenient to operate, and the measurement efficiency is low in actual use. Contents of the invention [0004] The problem solved by the present invention is to provide a pay-off device for land space planning and its use method, wh...
