[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1:

[0028] Based on the problems of traditional wire-laying devices, such as easy deviation, low efficiency, and poor adaptability during the wire-laying process, the present invention provides a preferred embodiment of a wire-laying device for engineering surveying, for example... Figures 1-4 As shown: A wire laying device for engineering surveying includes a support block 1, a wire laying extension adjustment part 3, and a wire laying guide part 4. A support leg is fixedly installed on the bottom outer wall of the support block 1, and a support pad 2 is fixedly installed on the bottom outer wall of the support leg. The wire laying extension adjustment part 3 is disposed inside the support block 1. The wire laying guide part 4 is disposed on the top outer wall of the wire laying extension adjustment part 3.

[0029] The wire extension adjustment part 3 specifically includes: a rotating positioning sleeve 311, which is fixedly installed on one side of the outer wall of the support block 1; a control button 312, which is fixedly installed at equal intervals on the outer wall of the support block 1; and a rectangular slide groove 319, which is formed on the support block 1.

[0030] Both sides of the inner wall of the rectangular slide groove 319 are provided with limit slide grooves 3111. The rotating positioning sleeve 311 is rotatably connected to a rotating rod 315. One end of the rotating rod 315 moves through the outer wall of the support block 1 and extends into the interior of the rectangular slide groove 319. One end of the rotating rod 315 is fixedly connected to a threaded screw 317.

[0031] The other end of the rotating rod 315 is fixedly connected to a rotating handle 314, and the other end of the threaded screw 317 is fixedly connected to a rotating block 3112. The rotating block 3112 is rotatably connected to the inner wall of the rectangular slide groove 319, and a rectangular slider 318 is slidably connected inside the rectangular slide groove 319.

[0032] Both outer walls of the rectangular slider 318 are fixedly connected to limit sliders 316, which are slidably connected to limit grooves 3111. A threaded connecting sleeve is fixedly installed on the outer wall of the rectangular slider 318, and the rectangular slider 318 is threadedly connected to the threaded screw 317 through the threaded connecting sleeve. An extension platform 313 is fixedly installed on the top outer wall of the rectangular slider 318.

[0033] In this embodiment, rotating the handle 314 causes the rotating rod 315 to rotate within the rotating positioning sleeve 311. Since one end of the rotating rod 315 is fixedly connected to a threaded screw 317, which is threadedly connected to a threaded connecting sleeve on the rectangular slider 318, and the limiting sliders 316 on both sides of the rectangular slider 318 slide within the limiting grooves 3111 on both sides of the inner wall of the rectangular groove 319, the movement trajectory of the rectangular slider 318 is restricted. As the handle 314 rotates, the rotation of the threaded screw 317 pushes the rectangular slider 318 to slide within the rectangular groove 319, thereby adjusting the extension length of the extension platform 313 to adapt to different distances of line laying requirements. During adjustment, the extension length can be controlled by observing the markings or scales around the control button 312 according to the actual situation. This adjustment function allows the line laying device to adapt to different length measurement requirements, improving its flexibility and convenience. In engineering surveying, terrain is often complex and varied. The design of the line laying extension adjustment section allows the line laying device to easily cope with various terrains.

[0034] Example 2:

[0035] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: the wire feeding guide 4 specifically includes: a fixing frame 411, which is fixedly installed on the top outer wall of the extension platform 313; a motor fixing frame 412, which is fixedly installed on one side outer wall of the fixing frame 411; a drive motor 413, which is disposed on one side outer wall of the fixing frame 411; and a support fixing block 419, which is disposed on the top of the extension platform 313.

[0036] A drive motor 413 is fixedly installed inside the drive motor 413. A rotating rod 414 is fixedly connected to the output end of the drive motor 413. A wire feeding wheel 415 is fixedly sleeved on the outer wall of the rotating rod 414. The other end of the rotating rod 414 movably passes through the outer wall of the fixed frame 411 and extends into the interior of the fixed frame 411. The other end of the rotating rod 414 is rotatably connected to the inner wall of the fixed frame 411. Fixed plates 416 are symmetrically fixedly installed on the outer wall of the fixed frame 411. Support rods 417 are rotatably connected between the fixed plates 416.

[0037] A guide pulley 418 is fixedly fitted on the outer wall of the support rod 417. The support fixing block 419 is symmetrically fixedly installed on the top outer wall of the extension platform 313. A rectangular fixing block 4111 is fixedly installed on the outer wall of the support fixing block 419. A sliding groove 4112 is opened on the rectangular fixing block 4111. A positioning rod 4115 is fixedly connected between the inner walls of the sliding groove 4112. A slider 4116 is slidably connected inside the sliding groove 4112. A sliding hole is opened on the slider 4116. The slider 4116 is movably fitted on the outer wall of the positioning rod 4115 through the sliding hole. A spring 4113 and a spring 4114 are movably fitted on the outer wall of the positioning rod 4115 respectively.

[0038] One end of spring 4113 is fixedly connected to the inner wall of slide 4112, and the other end of spring 4113 is fixedly connected to the top outer wall of slider 4116. One end of spring 4114 is fixedly connected to the inner wall of slide 4112, and the other end of spring 4114 is fixedly connected to the bottom outer wall of slider 4116. A wire block 4117 is fixedly installed between sliders 4116, and a wire through-hole 4118 is provided on the wire block 4117.

[0039] In this embodiment, the cable released from the cable release wheel 415 is initially guided by the guide pulley 418. The guide pulley 418 is rotatably connected to the fixed plate 416 via the support rod 417. Then, the cable passes through the wire opening 4118 on the wire block 4117. When the cable is subjected to upward or downward tension during the cable release process, the slider 4116 slides along the positioning rod 4115 in the groove 4112. Spring 1 4113 and Spring 2 4114 are respectively connected to the inner wall of the groove 4112 and the top and bottom outer walls of the slider 4116. When the cable tension changes, Spring 1 4113 and Spring 2 4114 will be compressed or stretched accordingly. The tension of the cable is automatically adjusted by the elastic force to ensure that the cable always maintains a suitable tension during the cable release process, and maintains appropriate pressure on the wire block and the wire opening. When the wire passes through the wire opening, the spring force can ensure that the wire is stably guided and fixed, avoiding the shaking of the wire and improving the accuracy and stability of the cable release.

[0040] Working principle: When in use;

[0041] Step 1: Place the support leg at the bottom of support block 1 stably on support pad 2 at the location where engineering measurement and layout are required, ensuring that support pad 2 is in full contact with the ground to provide stable support for the entire device and prevent shaking or displacement during the layout process;

[0042] Step 2: Rotate the handle 314. Rotating the handle 314 causes the rotating rod 315 to rotate within the rotating positioning sleeve 311. Since one end of the rotating rod 315 is fixedly connected to the threaded screw 317, the threaded screw 317 is threadedly connected to the threaded connecting sleeve on the rectangular slider 318. The limiting sliders 316 on both sides of the rectangular slider 318 slide within the limiting grooves 3111 on both sides of the inner wall of the rectangular groove 319, restricting the movement trajectory of the rectangular slider 318. As the handle 314 rotates, the rotation of the threaded screw 317 pushes the rectangular slider 318 to slide within the rectangular groove 319, thereby adjusting the extension length of the extension platform 313 to adapt to different distances of line laying requirements. During the adjustment process, the extension length can be controlled by observing the markings or scales around the control button 312 according to the actual situation.

[0043] Step 3: Install the cable to be released onto the cable feeding reel 415, and ensure that the cable is tightly and neatly wound. The drive motor 413 is fixed on the motor mounting bracket 412, which is installed on the outer wall of one side of the mounting bracket 411. Start the drive motor 413. The output end of the drive motor 413 drives the rotating rod 414 to rotate, which in turn drives the cable feeding reel 415 to rotate, and the cable feeding begins. The other end of the rotating rod 414 is rotatably connected to the inner wall of the mounting bracket 411 to ensure the stability of the rotation.

[0044] Step 4: The cable released from the cable release wheel 415 is initially guided by the guide pulley 418. The guide pulley 418 is rotatably connected to the fixed plate 416 via the support rod 417. Then the cable passes through the wire opening 4118 on the wire block 4117. When the cable is subjected to upward or downward tension during the cable release process, the slider 4116 slides along the positioning rod 4115 in the groove 4112. Spring 1 4113 and Spring 2 4114 are respectively connected to the inner wall of the groove 4112 and the top and bottom outer walls of the slider 4116. When the cable tension changes, Spring 1 4113 and Spring 2 4114 will be compressed or stretched accordingly, automatically adjusting the cable tension through elastic force to ensure that the cable always maintains a suitable tension during the cable release process.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
