[0028] like Figure 1-Figure 7 As shown, a construction measurement and setting-out device comprises a mobile base 1 for adjusting the setting-out measurement position, a placing box 2, a central control assembly 12 and a battery assembly 13 are fixedly mounted on the mobile base 1, a discharge port 8 is arranged on the side of the placing box 2, a wire-retracting and -releasing unit and a displacement unit are fixedly mounted in the placing box 2, a movable frame 7 is mounted on the displacement unit, a tensioning unit and a discharge unit for preventing the measuring wire from being loosened during the wire-retracting and -releasing process are mounted on the movable frame 7, the discharge unit and the discharge port 8 are at the same height, the discharge unit is located between the tensioning unit and the discharge port 8, the central control assembly 12 and the battery assembly 13 are electrically connected, the wire-retracting and -releasing unit, the displacement unit and the discharge unit are controlled to work by the central control assembly 12, and the battery assembly 13 is electrically connected to the central control assembly 12. The component 13 provides electric energy. When measuring, the entire pay-off device is moved to the site where it needs to be used through the mobile base 1, the pay-off unit is used to pay out the wire, the measuring wire is tensioned by the tensioning unit to prevent the measuring wire on the pay-off unit from being loose, and the measuring wire is taken out from the discharge port 8 by the discharging unit to complete the pay-off operation. During the pay-off process, the displacement unit drives the tensioning unit and the discharging unit to move back and forth in the placement box 2 through the movable frame 7, so that the measuring wires at different positions on the pay-off unit are evenly paid out. After the measurement is completed, the measuring wire is tightly wound on the pay-off unit with the cooperation of the tensioning unit, the discharging unit and the displacement unit, so as to improve the quality of winding and facilitate the next use.

[0029] like Figure 2-Figure 4As shown, the tensioning unit on the movable frame 7 includes a fixing plate 301, which is fixedly mounted on the movable frame 7, and an elastic mechanism and a self-resetting switch 309 are fixedly mounted on the lower surface of the fixing plate 301. A first mounting frame 304 is fixedly mounted on the lower end of the elastic mechanism, and two guide wheels 305 are rotatably mounted on the first mounting frame 304. A second telescopic rod 306 is fixedly mounted on the upper surface of the first mounting frame 304. The length of the second telescopic rod 306 is shorter than that of the elastic mechanism. A second spring 307 is sleeved on the second telescopic rod 306. A top plate 308 is fixedly mounted on the telescopic end of the second telescopic rod 306, and the top plate 308 is located at the self-resetting switch 309. 9, the top plate 308 is slidably connected to the self-resetting switch 309, and the self-resetting switch 309 is electrically connected to the central control component 12. In the line-release mode of the central control component 12, when the measuring line is released, the measuring line passes between the two guide wheels 305, and the measuring line is guided and limited by the guide wheels 305. Under the elastic force of the elastic mechanism, the elastic mechanism drives the guide wheels 305 to move through the first mounting frame 304, and the measuring line is tensioned by the guide wheels 305 to avoid the measuring line on the retractable line unit from being loosened due to the excessive release speed. At this time, under the elastic force of the second spring 307, the second telescopic rod 306 drives the top plate 308 to apply the self-resetting switch 309 When the force is applied, the self-resetting switch 309 works, the circuit between the central control component 12 and the self-resetting switch 309 is a passage, and the retractable line unit works normally. When the retractable line unit pays out too fast and the guide wheel 305 cannot tension the measuring line, the elastic mechanism reaches the maximum extension amount at this time. Since the elastic mechanism is longer than the second telescopic rod 306, under the elastic force of the second spring 307, the top plate 308 cannot contact the self-resetting switch 309, and the self-resetting switch 309 does not work. The connection between the central control component 12 and the self-resetting switch 309 is disconnected, and the retractable line unit is controlled by the central control component 12 to reduce the speed of the payout, so as to avoid the measuring line on the retractable line unit. The loose knots caused by paying out the line too quickly can effectively prevent the measuring line on the pay-out and take-up unit from being tangled together due to looseness, which reduces the pay-out speed. In the take-up mode of the central control component 12, the measuring line is tensioned by the guide wheel 305, so that the wound measuring line is tightly wound on the pay-out and take-up unit. During the take-up process, when the take-up speed of the pay-out and take-up unit is too slow and the guide wheel 305 cannot tension the measuring line, the top plate 308 disengages from the self-resetting switch 309, and the self-resetting switch 309 does not work. At this time, the central control component 12 controls the pay-out and take-up unit to increase the take-up speed, so as to prevent the measuring line from being tangled when taking up, which affects the next use, and improves the speed, quality and aesthetics of the measuring line winding.

[0030] like Figure 4As shown, the elastic mechanism on the fixed plate 301 includes a first telescopic rod 302, there are two first telescopic rods 302 and both are fixedly mounted on the fixed plate 301, the two first telescopic rods 302 are located on both sides of the second telescopic rod 306, the first telescopic rod 302 is longer than the second telescopic rod 306, the telescopic end of the first telescopic rod 302 is fixedly connected to the first mounting frame 304, and the first spring 303 is sleeved on the first telescopic rod 302. The first mounting frame 304 is elastically supported by the first telescopic rod 302 and the first spring 303, so that the guide wheel 305 can better tension the measuring line to avoid loosening of the measuring line when the line is retracted and released.

[0031] like Figure 1 , Figure 3 , Figure 6 As shown, the displacement unit in the placement box 2 includes a first motor 501 and a screw rod 502. The first motor 501 is fixedly installed on the side of the placement box 2, and the screw rod 502 is rotatably installed in the placement box 2. The screw rod 502 is threadedly connected to the movable frame 7, and the screw rod 502 is fixedly connected to the output shaft of the first motor 501. The first motor 501 is electrically connected to the central control component 12. The central control component 12 controls the operation of the first motor 501 using the existing technology. The first motor 501 drives the screw rod 502 to rotate forward and reverse, and the movable frame 7 is driven to move back and forth by the screw rod 502. The tensioning unit and the discharging unit are driven to move back and forth by the movable frame 7, so that the reeling unit can pay out the wire evenly. When reeling in the wire, it is avoided that the measuring line is concentrated at one position of the reeling unit for reeling in, thereby improving the uniformity of the reeling of the measuring line.

[0032] like Figure 2 , Figure 3 , Figure 5 As shown, the discharging unit on the movable frame 7 includes a second mounting frame 401, the second mounting frame 401 is mounted on the movable frame 7, an adjusting component 402 is arranged on the second mounting frame 401, an electric roller 403 is rotatably mounted on the adjusting component 402, an anti-skid roller 404 is fixedly mounted on the electric roller 403, there are two anti-skid rollers 404, the middle position of the two anti-skid rollers 404 corresponds to the center position of the discharging port 8, the electric roller 403 is electrically connected to the central control component 12, and the electric roller 403 is controlled by the central control component 12. The movable roller 403 adopts the existing technology to pass the measuring line between the two anti-slip rollers 404. The distance between the two anti-slip rollers 404 is adjusted by the adjustment component 402 so that the two anti-slip rollers 404 are in contact with the measuring line. During the process of winding and releasing the line, the anti-slip roller 404 is driven to rotate by the electric roller 403, and the measuring line is driven by the two anti-slip rollers 404, so as to complete the winding and releasing of the measuring line and increase the speed of winding and releasing the line. During the process of winding and releasing the line, the measuring line is pulled by the two anti-slip rollers 404.

[0033] like Figure 1 , Figure 2 , Figure 6 As shown, the wire reel 603 in the placement box 2 includes a second motor 601 and a mounting seat 602. The second motor 601 is fixedly mounted on the side of the placement box 2, and the mounting seat 602 is rotatably mounted on both sides of the inside of the placement box 2. One mounting seat 602 is fixedly connected to the output shaft of the second motor 601, and a wire wheel 603 is fixedly mounted between the two mounting seats 602. The second motor 601 and the central control component 12 are electrically connected, and the central control component 12 controls the operation of the second motor 601 using the existing technology. The second motor 601 drives the wire wheel 603 to rotate through the mounting seat 602, and the wire reel 603 is used to reel in and out the measuring wire. By automatically reeling in and out the wire, the speed of reeling in and out is increased, and the workload of the staff is reduced.

[0034] like Figure 2 , Figure 6 , Figure 7 As shown, a cleaning roller 9 for cleaning the measuring line is rotatably installed on the side of the placement box 2. The cleaning roller 9 is located on the upper and lower sides of the discharge port 8. The measuring line entering the discharge port 8 is cleaned by the cleaning roller 9 to reduce dirt on the measuring line and prevent dirt from adhering to the measuring line and affecting the service life of the measuring line, so as to facilitate the next use.

[0035] like Figure 1 , Figure 2 , Figure 7 As shown, the upper surface of the placement box 2 is provided with an observation window 10 for observing the interior of the placement box 2, and a transparent plate 11 is fixedly installed in the observation window 10. During the process of retracting and releasing the wire, the interior of the placement box 2 can be easily observed through the observation window 10 and the transparent plate 11.

[0036] Working principle: Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, the entire pay-off device is moved to the site where it needs to be used by moving the base 1, and the second motor 601 is controlled to work by the central control component 12. The second motor 601 drives the wire wheel 603 to rotate through the mounting seat 602, so that the measuring line of the wire wheel 603 is paid out;

[0037] like Figure 2 , Figure 3 , Figure 5 As shown, the anti-skid roller 404 is driven to rotate by the electric roller 403, and the measuring line is driven by the two anti-skid rollers 404, so that the measuring line is led out through the discharge port 8, and the measuring line is pulled by the two anti-skid rollers 404 in cooperation with the wire wheel 603;

[0038] like Figure 2-Figure 4As shown, during the line-releasing process, the first mounting frame 304 is elastically supported by the first telescopic rod 302 and the first spring 303, and the first mounting frame 304 drives the guide wheel 305 to tension the measuring line. At this time, under the elastic force of the second spring 307, the second telescopic rod 306 drives the top plate 308 to apply a force to the self-resetting switch 309, and the self-resetting switch 309 works. The circuit between the central control component 12 and the self-resetting switch 309 is a passage, and the wire wheel 603 releases the wire normally;

[0039] like Figure 2-Figure 4 As shown, in the wire-releasing mode of the central control component 12, when the wire-releasing speed of the wire wheel 603 is too fast, the slack degree of the measuring wire exceeds the support range of the first spring 303 and the first telescopic rod 302. At this time, the guide wheel 305 cannot tighten the measuring wire, the top plate 308 cannot contact the self-resetting switch 309, the self-resetting switch 309 does not work, the central control component 12 and the self-resetting switch 309 are disconnected, and the second motor 601 is controlled by the central control component 12 to reduce the wire-releasing speed of the wire wheel 603, so as to avoid the measuring wire on the wire wheel 603 being loose due to excessive wire-releasing speed;

During the winding process, the wound measuring wire is tensioned by the guide wheel 305 so that the wound measuring wire can be tightly wound around the wire wheel 603. During the winding process, when the winding speed of the wire wheel 603 is too slow and the guide wheel 305 cannot tension the measuring wire, the top plate 308 is separated from the self-resetting switch 309, and the self-resetting switch 309 does not work.
