[0023] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0024] See Figures 1 to 5This embodiment discloses a surveying and setting-out device for construction engineering, including a surveying and setting-out box 1. The surveying and setting-out box 1 is equipped with a setting-out assembly, which includes a winding shaft 2 and a connecting plate 3. One end of the surveying line is wound on the winding shaft 2, and the other end is fixed on the connecting plate 3. The winding shaft 2 is vertically rotatable and installed in the inner cavity of the surveying and setting-out box 1. The upper and lower ends of the winding shaft 2 are respectively provided with limiting blocks 4, which are rotatably engaged with two limiting slots 12 provided in the surveying and setting-out box 1 to prevent the winding shaft 2 from moving vertically. The upper end of the winding shaft 2 extends upward above the top of the surveying and setting-out box 1 and is provided with a hand crank 5. The connecting plate 3 is slidably set in the installation opening 6 on the rear side of the surveying and setting-out box 1 and can slide back and forth along the installation opening 6. The rear end of the connecting plate 3 extends out of the surveying and setting-out box 1 and is fixedly connected to the counterweight bracket 7. The bottom of the counterweight bracket 7 is provided with multiple downwardly extending fixing pins 8, and the counterweight bracket 7 is fixed to the ground soil by the fixing pins 8. The counterweight support 7 is an L-shaped support. The front of the vertical section of the counterweight support 7 is fixed to the connecting plate 3. An auxiliary groove 9 is opened on one side of the vertical section of the counterweight support 7, and a handle 10 is provided in the auxiliary groove 9 to facilitate lifting the counterweight support 7. Multiple fixing pins 8 are set at the bottom of the horizontal section of the counterweight support 7. The front of the horizontal section of the counterweight support 7 is detachably connected to the rear of the measuring wire box 1. Multiple latches 11 are provided on the front of the horizontal section of the counterweight support 7, and multiple slots 12 are opened on the rear of the measuring wire box 1. The multiple latches 11 and multiple slots 12 are inserted and matched one-to-one to realize the detachable connection between the counterweight support 7 and the measuring wire box 1.

[0025] The measuring wire laying box 1 is a movable box. The bottom of the measuring wire laying box 1 is equipped with four movable rollers 13, and the top of the measuring wire laying box 1 is equipped with a portable component, which enables the measuring wire laying box 1 to be pulled forward or lifted upward.

[0026] The portable component includes a U-shaped wire-feeding handle 14. The open end of the wire-feeding handle 14 is rotatably mounted on the top of the measuring wire-feeding box 1 near the front via a rotating shaft 15 extending left and right. The wire-feeding handle 14 can rotate around the rotating shaft 15. Specifically, the top of the measuring wire-feeding box 1 near the front has two lugs 16, and the inner side of each lug 16 is provided with a rotating shaft 15. The left and right sides of the open end of the wire-feeding handle 14 are hinged to the rotating shafts 15 inside the lugs 16. The closed end of the wire-feeding handle 14 is detachably connected to the top of the measuring wire-feeding box 1 near the rear. A handle 17 is provided across the middle section of the wire-feeding handle 14. The left and right ends of the closed end of the wire feeding handle 14 have through holes 18. Two adjusting screws 19 pass through the two through holes 18 and are tightened into the two threaded holes 20 on the top of the measuring wire feeding box 1, thus fixing the closed end of the wire feeding handle 14 to the measuring wire feeding box 1. This allows for both storage of the wire feeding handle 14 and lifting of the entire measuring wire feeding box 1 upwards via the handle 17 for easy carrying. Loosening the two adjusting screws 19 releases the closed end of the wire feeding handle 14, allowing it to rotate forward and upward around the rotating shaft 15. Combined with the four moving rollers 13 at the bottom of the measuring wire feeding box 1, the measuring wire feeding box 1 can be easily moved forward via the wire feeding handle 14 for wire feeding. Operating the two adjusting screws 19 allows for flexible switching between the handle 17 and the handle of the measuring wire feeding box 1. The head of the adjusting screw 19 is equipped with an adjusting knob 21 for easy turning of the adjusting screw.

[0027] The working process of the building engineering surveying and setting-out device provided in this embodiment is as follows:

[0028] When it is time to lay out the wire, first remove the counterweight bracket 7 from the back of the measuring wire laying box 1 and fix it in place by inserting the fixing pin 8 into the ground soil. This fixes the connecting plate 3, which is fixed to the counterweight bracket 7, thus securing one end of the measuring wire. The weight of the counterweight bracket 7 itself enhances its stability. Loosen the two adjusting screws 19 and rotate the wire laying handle 14 forward and upward around the rotating shaft 15. With the help of the four moving rollers 13 at the bottom of the measuring wire laying box 1, the measuring wire laying box 1 can be easily moved forward by pulling the wire laying handle 14 to lay out the wire. After laying out the wire, when it is time to reel it in, rotate the winding shaft 2 by using the hand crank 5 to reel in the measuring wire. The entire wire laying and reeling process is convenient, quick, and saves time and effort.

[0029] When the device is not in use, the counterweight bracket 7 can be stored in the rear of the measuring wire feeding box 1 by inserting multiple bolts 11 into the multiple slots 12 one by one; at the same time, the wire feeding handle 14 is flipped backward and downward around the rotating shaft 15, and two screws are passed through the two through holes 18 and tightened into the two threaded holes 20 on the top of the measuring wire feeding box 1, thereby fixing the closed end of the wire feeding handle 14 to the measuring wire feeding box 1, thus storing and fixing the wire feeding handle 14 on the top of the measuring wire feeding box 1; at this time, the entire measuring wire feeding box 1 can be lifted upward by the handle 17 for easy carrying.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
