AI Technical Summary
Existing engineering surveying and setting-out devices lack guiding and adjusting mechanisms during the wire retrieval process, resulting in uneven wire retrieval, overlap, loosening, or local accumulation, which reduces operational efficiency and measurement accuracy.
A second motor drives the take-up roller to rotate, which in turn drives the slider to move along the lead screw, achieving uniform winding of the wire. The wire surface is cleaned with cleaning cotton, and an electric push rod is used to press the wire to fix it and ensure the wire is taut.
This achieves uniform winding of the wire, improves measurement accuracy and operational efficiency, and ensures the accuracy of measurement results.

Description
Technical Field
[0001] This utility model belongs to the field of engineering surveying technology, and in particular to an engineering surveying and setting-out device. Background Technology
[0002] In existing engineering surveying, measuring instruments are generally used to measure designated locations, and then the measurements are...
[0003] The result is used to lay out and retract the wire, and then proceed with subsequent operations such as concrete pouring.
[0004] However, there is currently no adjustable engineering surveying and setting-out device. Most existing engineering surveying and setting-out devices only rely on the cooperation between their mounting plate, winding roller, clamping block, clamping groove, and fixing frame. For example, the utility model patent disclosed in Chinese Patent Publication No. CN222118543U uses a winding roller that lacks a guiding adjustment mechanism during the winding process. This results in the wire not being evenly distributed along the axial direction of the winding roller when it is being retracted, which easily leads to overlapping, loosening, or local accumulation of the wire. This results in reduced operating efficiency, increased risk to measurement accuracy, and decreased equipment reliability. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide an engineering measurement and laying-out device that can solve the defect of existing devices in uniformly retracting the line after laying out the line. It is simple to operate and has high measurement accuracy.
[0006] The technical solution adopted in this utility model is as follows:
[0007] An engineering surveying and setting-out device includes a base plate. A first fixed plate and a second fixed plate are symmetrically fixedly mounted on the front and rear sides of the top of the base plate. A second motor is fixedly mounted on the second fixed plate. A rotating shaft is fixedly mounted on the output shaft of the second motor. The rotating shaft passes through both the first and second fixed plates and is rotatably connected to them. A take-up roller is fixedly mounted on the outer side of the rotating shaft, located between the first and second fixed plates. The first motor is fixedly mounted on the rear side of the top of the base plate. A slide rail is fixedly mounted on the top of the base plate. A lead screw is fixedly mounted on the output shaft of the first motor. A slider is threadedly connected to the outer side of the lead screw. The slider is slidably connected to the slide rail. A first through hole is formed on the slider, and a cleaning cotton is placed inside the through hole. A second perforation is formed inside the cleaning cotton.
[0008] Preferably, a mounting plate is fixedly installed on one side of the cleaning cotton.
[0009] Preferably, the mounting plate is fixedly connected to the slider, and a second through hole is provided on the mounting plate at the position corresponding to the second through hole.
[0010] Preferably, the slider is fixedly connected to the mounting block via a connecting block, and the mounting block has a first through hole at the position corresponding to the second through hole.
[0011] Preferably, the mounting block has a mounting groove, and an electric push rod is fixedly installed on the bottom side inside the mounting groove.
[0012] Preferably, a pressing block is fixedly installed at the push rod end of the electric push rod, and the pressing block extends out of the mounting groove and is inserted into the interior of the first through hole.
[0013] Preferably, a switch is fixedly installed on the first or second fixed plate, and the first motor, the second motor, and the electric push rod are all electrically connected to the switch via wires and then to an external power supply.
[0014] The engineering surveying and setting-out device provided by this utility model has the following advantages:
[0015] 1. The first motor is started while the second motor drives the take-up roller to rotate. The first motor drives the slider to move back and forth along the lead screw. At this time, the wire will be evenly wound on the outside of the take-up roller, achieving the effect of uniform winding.
[0016] 2. Cleaning cotton is placed inside the slider. It can clean the surface of the wire when the wire is wound up. At the same time, after the wire is pulled out, the electric push rod can drive the compression block to compress and fix the taut wire, ensuring that the wire is always in a taut state, thereby ensuring the accuracy of the measurement results.
[0017] It can solve the problem of existing devices that uniformly retract the wire after it has been laid out, and it is simple to operate and has high measurement accuracy. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-3As shown, an engineering surveying and setting-out device includes a base plate 3. A first fixing plate 2 and a second fixing plate 2' are symmetrically fixedly installed on the front and rear sides of the top of the base plate 3. A second motor 18 is fixedly installed on the second fixing plate 2'. A rotating shaft 5 is fixedly installed on the output shaft of the second motor 18. The rotating shaft 5 passes through the first fixing plate 2 and the second fixing plate 2' and is rotatably connected to the first fixing plate 2 and the second fixing plate 2'. A take-up roller 1 is fixedly installed on the outer side of the rotating shaft 5 and at a position between the first fixing plate 2 and the second fixing plate 2'. A first motor 4 is fixedly installed on the rear side of the top of the base plate 3. A slide rail 9 is fixedly installed on the top of the base plate 3. A lead screw 7 is fixedly installed on the output shaft of the first motor 4. A slider 8 is threadedly connected to the outer side of the lead screw 7. The slider 8 is slidably connected to the slide rail 9. A first through hole is opened on the slider 8. A cleaning cotton 17 is placed inside the through hole. A second through hole 16 is opened inside the cleaning cotton 17.
[0024] A mounting plate 6 is fixedly installed on one side of the cleaning cotton 17.
[0025] Mounting plate 6 is fixedly connected to slider 8 by multiple screws, and a second through hole is provided on mounting plate 6 at the position corresponding to the second through hole 16.
[0026] The slider 8 is fixedly connected to the mounting block 15 via the connecting block 10. The mounting block 15 has a first through hole 13 at the position corresponding to the second through hole 16.
[0027] The mounting block 15 has a mounting groove 11, and an electric push rod 12 is fixedly installed on the bottom side of the inside of the mounting groove 11.
[0028] An extrusion block 14 is fixedly installed on the push rod end of the electric push rod 12. The extrusion block 14 passes through the mounting groove 11 and is inserted into the first through hole 13.
[0029] A switch is fixedly installed on the first fixed plate 2 or the second fixed plate 2'. The first motor 4, the second motor 18 and the electric push rod 12 are all electrically connected to the switch through wires and then to an external power supply.
[0030] The working process of this utility model is as follows:
[0031] In use, the wire is passed through the through hole on the mounting plate 6 and then through the second through hole 16 on the cleaning cotton 17. After passing through the second through hole 16, it is passed through the first through hole 13 on the mounting block 15. Then, the required length is pulled out to release the wire. When one end of the wire reaches the predetermined position, hold one end of the wire still and start the second motor 18 to drive the rotating shaft 5 to rotate. The rotating shaft 5 drives the winding roller 1 to rotate and wind up the wire. When the operator feels the wire is taut, stop the second motor 18 and start the electric push rod 12 to drive the pressing block 14 to be inserted into the first through hole 13 to press the wire, so that the pulled-out wire is in a taut state.
[0032] When the wire needs to be wound up, the push rod end of the electric push rod 12 is retracted so that the extrusion block 14 no longer extrudes the wire. The first motor 4 is started, and the first motor 4 drives the slider 8 to reciprocate along the slide rail 9 outside the lead screw 7, so that the wire is evenly wound on the outside of the take-up roller 1. During the winding process, the wire will pass through the cleaning cotton 17, which will clean the surface of the wire. The cleaning cotton 17 can be pulled out after removing the screws on the mounting plate 6 for replacement.
