Description

Technical Field

[0001] The invention relates to the technical field of leveling, in particular to a horizontal marking device used for real estate surveying and mapping. Background Art

[0002] In real estate surveying and mapping, the horizontal marking device is one of the core tools to ensure measurement accuracy and work efficiency. The horizontal marking device generates a stable horizontal reference line (or surface) through physical or optical means, provides a reference coordinate system for surveying and mapping operations, eliminates errors caused by surface undulations or building structure inclinations, and ensures that data from different measuring points are in the same horizontal system. In mobile measurement, the device posture deviation can be corrected in real time to avoid data distortion caused by equipment tilt. Therefore, it can be used for tasks such as wall verticality detection, floor elevation transfer, plot boundary calibration, and settlement deformation analysis.

[0003] The laser level marking device in the prior art can only adjust the height of its marking according to its bottom support structure, and can only provide a fixed laser level at a time. If the height difference between two levels needs to be calculated, it is necessary to irradiate different positions multiple times and then perform sequential measurement and calculation to complete it. Therefore, it is not flexible enough, and the measurement of farther positions will be further increased. On the other hand, the conventional laser level marking device realizes the level marking function through a built-in gyroscope. Whether the projected horizontal line has errors needs to be manually calibrated regularly. The calibration process is time-consuming and labor-intensive, and the operation is difficult.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a horizontal marking device for real estate surveying and mapping, comprising a marking device body, the marking device body comprising a control platform 1, an angle adjustment mechanism 4, a locking mechanism 5 and a calibration component 6, a first level 2 and a second level 3 are installed on the surface of the control platform 1, the bottom of the first level 2 and the surface of the control platform 1 are screwed as a whole, an angle adjustment mechanism 4 is installed on the bottom of the control platform 1, a slide groove 13 and a strip hole 14 are opened on the surface of the control platform 1, the bottom of one end of the locking mechanism 5 is embedded in the interior of the slide groove 13, an extension plate 15 is integrally formed in the control platform 1 area at one end of the strip hole 14, a calibration component 6 is inserted into the interior of the strip hole 14, a transmission sleeve 9 is welded on the top of the transmission sleeve 9, a column 10 is welded on the top of the column 10, a distance measuring module 11 is screwed on the top of the column 10, and a screw rod 17 is inserted into the interior of the strip hole 14. The surveying and mapping horizontal marking device uses a first level meter 2 and a second level meter 3 to respectively emit horizontal laser beams at two heights of a target area to perform marking processing.

[0029] When the present invention is used, after supporting the control platform 1 with the help of an external supporting device, the first level 2 is started, and the first level 2 is used to irradiate the first horizontal laser beam toward the front, and then the second level 3 can be controlled to tilt up through the angle adjustment mechanism 4 at the bottom, and the distance to the target that the two levels need to irradiate can be obtained through the distance measuring module 11 on the control platform 1. Since the distance measuring module 11 measures the vertical line distance between the target area, and the measuring point of the distance measuring module 11 is on the horizontal line irradiated by the first level 2, the distance between the second level 3 irradiating the target vertical plane and the horizontal line irradiated by the first level 2 can be controlled by controlling the tilting angle of the second level 3, so that the two required horizontal marking lines can be quickly obtained at the same time. After completing the control and irradiation of the second level 3, the second level 3 can be locked with the help of the locking mechanism 5 to prevent the level from moving downward and shaking, and the calibration component 6 can be regularly controlled to calibrate the horizontality of the two levels in turn.

[0030] In this embodiment, the rear end of the second level 3 is integrally formed with a rotating column 22, the surface of the rotating column 22 is provided with a slot 23, one end of the rotating column 22 is integrally formed with a driven shaft 24, and the surface of the driven shaft 24 is keyed to a driven gear 25. The angle adjustment mechanism 4 includes a motor 19 and a driving gear 21, a driving box 8 is welded to the bottom of the control platform 1, one end of the driving box 8 is provided with an end plate 7, the outer shell of the motor 19 is screwed to the outside of the end plate 7, the output end of the motor 19 is inserted with a driving shaft 20, and the driving gear 21 is keyed to the surface of the driving shaft 20. The driving shaft 20 and the driving gear 21 are both embedded in the interior of the driving box 8, and the end of the driving shaft 20 is embedded in the inner wall of the driving box 8 through a bearing, the driving gear 21 and the driven gear 25 are meshed, and the driving box 8 and the interior of the transmission sleeve 9 are connected. It is capable of projecting two horizontal lines at the same time. The first level 2 is always positioned horizontally to project a horizontal line, while the second level 3 projects the second horizontal line in a tilted form through the angle adjustment mechanism 4 at the bottom. Together with the distance measuring module 11 in the middle, the height difference between different horizontal lines on the same vertical plane can be quickly calculated, which has higher flexibility and simplifies the surveying and mapping task operations that require multiple horizontal lines.

[0031] Specifically, after starting the motor 19, the motor 19 controls the driving shaft 20 to rotate, and the driving shaft 20 drives the active gear 21 on the surface, thereby controlling the driven gear 25 to rotate, and the driven gear 25 drives the inner driven shaft 24 to rotate, and the driven shaft 24 controls the rotation of the rotating column 22 at the end, so that the entire second level 3 can be tilted around the rotating column 22 at the rear end, thereby changing the height of the laser line emitted by the second level 3 on the target vertical surface.

[0032] In this embodiment, the locking mechanism 5 includes a sliding seat 26 and a pushing screw 30. A convex plate 12 is welded to the side of the control platform 1. A pushing screw 30 is inserted in the middle of the convex plate 12. A hand wheel 31 is integrally formed at one end of the pushing screw 30. The bottom of the sliding seat 26 is embedded in the inside of the slide groove 13. The other end of the pushing screw 30 is movably connected to the side of the sliding seat 26 through a bearing. A support plate 27 is integrally formed on the top of the sliding seat 26. An arc-shaped piece 28 is integrally formed on the surface of the support plate 27. A ball 29 is embedded on the surface of the arc-shaped piece 28. The support plate 27 rests on the surface of the rotating column 22. The arc-shaped piece 28 is embedded in the inside of the card slot 23. The sliding seat 26 performs translational movement along the inside of the slide groove 13 through the pushing screw 30. The sliding seat 26 squeezes the inner wall of the card slot 23 through the arc-shaped piece 28. After the angle adjustment module completes the adjustment of the horizontal line angle projected by the second level 3, the side locking mechanism 5 is used to provide a pushing effect on part of the second level 3. This effect can ensure that the second level 3 will not be easily disturbed by external forces and shake during the subsequent long-term marking process, thereby improving the stability of the horizontal line irradiation.

[0033] Specifically, the process of tilting the second level 3 by the angle adjustment mechanism 4 will always be supported by the support plate 27 at the rear end, and with the help of the ball 29 on the arc piece 28 as the main supporting structure, the resistance generated when the second level 3 rotates is reduced, and after the angle adjustment is completed, the hand wheel 31 is manually turned, and the extrusion screw is controlled by the hand wheel 31 to translate, which can drive the sliding seat 26 to move along the slide groove 13. This movement process can directly press each arc piece 28 against the inner wall of the slot 23 and generate a large extrusion force, which can directly lock the rotating column 22. Therefore, once the inclination adjustment of the second level 3 is completed by the angle adjustment mechanism 4, even if the subsequent motor 19 is partially powered off, the problem of the second level 3 falling due to being touched by external force can still be avoided, so as to achieve long-term marking use and reduce the impact of external interference.

[0034] In this embodiment, a lower hanging plate 16 is welded to the bottom of the side of the control platform 1, the screw rod 17 passes through the middle of the lower hanging plate 16, and a knob 18 is integrally formed at one end of the screw rod 17. The calibration component 6 includes a detection chamber 32, a light inlet 33 and a photosensitive module 35. A light inlet 33 is provided at the front end of the detection chamber 32, a light shielding plate 34 is welded to the side of the light inlet 33, and a photosensitive module 35 is screwed inside the detection chamber 32. The light inlet 33 and the light shielding plate 34 are both triangular structures as a whole. A vertical plate 36 is integrally formed at the bottom of the detection chamber 32, and a threaded sleeve 37 is provided at the bottom of the vertical plate 36. The screw rod 17 passes through the inside of the threaded sleeve 37, and the light inlet 33 is used to receive the horizontal laser beam emitted from the first level 2 and the second level 3. A calibration component 6 is installed at the end of the control platform 1. With the help of the calibration component 6, it can slide over the front end of the first level 2 and the second level 3 in turn, and by detecting the amount of incoming light, the horizontality of the horizontal lines projected by the two levels can be quickly calibrated and detected, so that deviations in the levels can be detected in time.

[0035] Specifically, when calibrating and testing the two levels, first control the second level 3 to rotate downward through the angle adjustment mechanism 4, and reach the same height as the first level 2 for irradiation. At this time, manually turn the knob 18, and with the help of the rotation of the screw rod 17, cooperate with the threaded sleeve 37 to control the detection chamber 32 to slide along the strip hole 14, and move the light inlet 33 part in front of the laser beam emitted by the first level 2 and the second level 3 in turn. When the laser beam emitted by any level is tilted, it will cause the length of the laser beam emitted by the level to increase at the light inlet 33, and then cause the light entering the light inlet 33 to increase, and the brightness sensed by the internal photosensitive module 35 to increase. Therefore, by moving through the irradiation range of the two levels in turn, and detecting the brightness after moving through the two areas, it is possible to determine whether the two levels are completely consistent, thereby achieving the effect of mutual comparison and verification.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
