In the process of engineering construction, the portable laying-out measuring device is an important tool that can help engineers and construction personnel to perform accurate laying-out and measurement work to ensure the accuracy and quality of the project. Existing portable laying-out measuring devices, such as Chinese patent authorization announcement number: CN222063771U, discloses a portable laying-out measuring device, which, through a simple installation structure, makes it convenient to reel in the measuring line while also facilitating laying-out measurement. It is very flexible and convenient to use, meets a variety of usage needs, and effectively improves measurement efficiency. However, the above structure does not disclose a measuring unit, and the existing measuring device, regardless of whether the winding and laying-out measuring units are in working condition, is prone to wear of the measuring roller or fatigue damage of the measuring unit, resulting in measurement errors. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a portable laying-out measuring device, which can lay out the wires according to the measurement requirements.

At this time, the controller sends a signal to the winding motor, and the winding motor drives the entire one-way bearing to rotate, thereby driving the winding drum to rotate synchronously to rewind the wire, so as to achieve the winding of the measuring line, until the hanging ring abuts against the wire roller assembly, and the winding motor stops moving. At this time, the calibration before measuring the measuring line is completed; then , you can measure and release the line. Since the internal rotating end of the one-way bearing can rotate in one direction, if the one-way bearing rotates clockwise, the internal rotating end of the one-way bearing rotates counterclockwise to lock it. Therefore, set the line-release rotation direction of the winding drum to clockwise release, that is, set the line-release rotation direction of the winding drum and the one-way rotation direction of the one-way bearing to the same direction; when pulling the measuring line, the winding drum and the internal rotating end of the one-way bearing rotate synchronously clockwise to release the line. When reeling in the line, since the internal rotating end of the one-way bearing rotates counterclockwise to lock it, state, therefore, the one-way bearing outer sleeve is driven to rotate by the winding motor, driving the one-way bearing as a whole to rotate, so as to realize the counterclockwise winding of the winding drum; when releasing the wire, the hanging ring is pulled, and when the measuring wire is pulled, it is guided by the wire roller assembly, and then pulled by the tensioning roller, so that the measuring wire is pressed onto the detection roller.

During the reeling process, when the hanging ring is stretched and abutted against the upper guide roller and the lower guide roller, the reeling motor is manually controlled to stop.

[0016] Furthermore, the installation position of the conductor roller assembly is lower than the installation position of the measuring roller assembly, so that when the measuring line is separated from the measuring roller assembly, the measuring line can be stretched and laid between the stretching roller and the conductor roller assembly.
