[0003] After retrieval, the Chinese patent with the publication number: CN216645353U discloses a portable setting-out measuring device for project cost measurement. It is recorded in this patent that by fixing one end of the measuring line to the outside, and then the staff directly drives the shell to move, so that the measuring line drives the wire-receiving one-way bearing to rotate and release the measuring line from the inside of the shell. The staff can arrange the measuring line by driving the shell to move, ensuring data collection for project cost assessment of buildings in some special environments through the shell, and ensuring the working efficiency of the staff.

[0004] In this scheme, although it is convenient to carry the device to move for measurement, when taking in the line, only the wire-receiving one-way bearing is used to take in the line, resulting in the problem of messy winding and non-uniformity during the line-taking-in process, and the space cannot be fully utilized, thus leading to the need to disassemble the device for sorting, greatly reducing the working efficiency. To solve this technical problem, the utility model proposes a project cost measurement and setting-out device. Summary of the Invention

Specific Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] Embodiment 1: A construction cost measurement and setting-out device, including a base 1, a fixed frame 2 is fixedly connected to the top of the base 1, a fixed column 3 is fixedly connected to one side of the top of the base 1, and a winding mechanism 4 is arranged on the top of the base 1 at the same time. The winding mechanism 4 includes a motor 401, the motor 401 is fixedly connected to the top of the fixed column 3, the output end of the motor 401 is fixedly connected to a rotating rod 402, a first gear 403 is fixedly connected to the outer wall of one end of the rotating rod 402, and at the same time, a pair of brackets 6 are fixedly connected to the outer wall of one side of the fixed frame 2, and a threaded rod 405 is rotatably connected inside the bracket 6. A second gear 404 is fixedly connected to the outer wall of one end of the threaded rod 405, and the second gear 404 meshes with the first gear 403. A connecting block 406 is threadedly connected to the outer wall of the threaded rod 405, a positioning block 407 is fixedly connected to the bottom of the connecting block 406, a positioning rod 408 is fixedly connected between the two brackets 6, and the positioning block 407 is slidably connected to the outer wall of the positioning rod 408. The rotating rod 402 is rotatably connected inside the fixed frame 2, a winding roller 5 is fixedly connected to the outer wall of the rotating rod 402, the winding roller 5 is rotatably connected inside the fixed frame 2, a pair of connecting frames 409 are fixedly connected to the top of the connecting block 406, and an inner rod 410 is rotatably connected between the two connecting frames 409. At the same time, a roller 411 is fixedly connected to the outer wall of the inner rod 410.

[0027] The start of the motor 401 drives the rotating rod 402, thereby driving the winding roller 5 to pay out the line. At the same time, the movement of the rotating rod 402 causes the first gear 403 and the second gear 404 on the bracket 6 to start rotating. The rotation of the second gear 404 guides the threaded rod 405 to rotate, thereby moving the connecting block 406, causing the connecting block 406 to move left and right, so as to adjust the position of the measuring line between the rollers 411 on the inner rod 410. The connecting block 406 is limited by the positioning block 407 to ensure that the moving direction is consistent, and the moving speed is synchronized with the line paying-out speed of the winding roller 5. When the motor 401 is operated in reverse, the winding roller 5 starts to take in the line, ensuring that the wire harness is neatly wound on the winding roller 5, avoiding chaos, and effectively improving the work efficiency.

[0028] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a support frame 7 is fixedly connected to the top of the fixed frame 2, three sliding rods 8 are slidably connected inside the support frame 7, the sliding rods 8 penetrate through the support frame 7 and are fixedly connected to a pressing rod 11, and the pressing rod 11 corresponds to the winding roller 5. Three springs 10 are fixedly connected to the top of the support frame 7, the springs 10 are sleeved on the outer walls of the sliding rods 8, a limiting ring 9 is fixedly connected to the outer wall above the sliding rods 8, and at the same time, the other ends of the springs 10 are fixedly connected to the bottom of the limiting ring 9.

[0029] During the process of winding and unwinding the wire harness, due to the change in the thickness of the wire harness on the winding roller 5, especially when the wire harness is thick, we use the pressing rod 11 at the bottom of the sliding rod 8 on the support frame 7 to press the wire harness tightly to prevent the wire harness from coming loose. By pushing the pressing rod 11, the sliding rod 8 will push up the limiting ring 9, and through the spring-back effect of the spring 10 of the limiting ring 9, the wire harness on the winding roller 5 will be tightly pressed to ensure that the wire harness can maintain a normal winding and unwinding effect. This design can effectively address the challenges brought about by the change in the thickness of the wire harness and ensure that the wire harness always remains neat during the operation process.

[0030] Working principle: When measuring in project cost, a wire releasing device will be used. At this time, it is placed on a flat place through the base 1, and the wire harness on the winding roller 5 is passed through between a pair of rollers 411. By starting the motor 401, under the action of the motor 401, the rotating rod 402 is driven to rotate. The rotation of the rotating rod 402 will drive the winding roller 5 to rotate and release the wire. At the same time, the rotation of the rotating rod 402 will drive the first gear 403 to rotate. When the first gear 403 rotates, it will drive the second gear 404 on the support frame 6 to rotate. When the second gear 404 rotates, it will drive the threaded rod 405 to rotate. When the threaded rod 405 rotates, it will drive the connecting block 406 to move left and right, thereby driving the measuring wire between the rollers 411 on the inner rod 410 to move. And when the connecting block 406 moves, it is limited on the positioning rod 408 through the positioning block 407 to ensure that the direction of the connecting block 406 remains consistent when it moves, and the moving speed of the connecting block 406 is the same as the rotating speed of the winding roller 5. Reverse-start the motor 401, and the wire is wound through the winding roller 5. Through their cooperation, the wire can be neatly wound on the winding roller 5 during winding, avoiding the problem of mess and improving work efficiency. During winding and unwinding, due to the gradual change in the thickness of the wire harness on the winding roller 5, at this time, the pressing rod 11 at the bottom of the sliding rod 8 on the support frame 7 is used to press the wire harness to avoid the problem of the wire harness coming loose. When the wire harness is thick, push up the pressing rod 11. At this time, the sliding rod 8 pulls up the limiting ring 9 through the limiting ring 9, and through the resilience of the limiting ring 9, the wire harness on the winding roller 5 will be tightly pressed, so that the wire harness on the winding roller 5 can maintain a normal winding and unwinding effect.
