Description

Technical Field

[0001] This invention relates to the field of construction surveying technology, specifically to an automated elevation transfer and elevation setting surveying device and its usage method. Background Technology

[0002] In building construction, elevation control measurement is crucial for construction operations. Existing elevation transfer methods generally include total station zenith distance measurement and steel tape measurement. Steel tape measurement is unsuitable for super-high-rise building construction, while total station zenith distance measurement, using an electronic distance measuring system in conjunction with a prism or reflector, provides high accuracy and is therefore widely used. However, in practice, the total station zenith distance measurement method requires the coordinated operation of a forced centering device, total station, and camera receiver, as well as multiple measurements and tedious manual operation. Although the measurement accuracy meets construction requirements, a certain degree of error still exists, and these errors accumulate, ultimately leading to poor measurement accuracy. Furthermore, the operation requires multiple people to work together, and adjustments are cumbersome and time-consuming, significantly impacting the construction schedule. This invention provides an automated elevation transfer and elevation setting measurement device and method to solve the above problems. Summary of the Invention

The mounting base is located on a lifting platform. The laser rangefinder, automatic leveling seat, and control system are located on the mounting base. The laser rangefinder and the reflector are arranged vertically and vertically. The horizontal laser emitter is located on the automatic leveling seat. The control system is electrically connected to the horizontal laser emitter, the laser rangefinder, and the lifting platform.

[0008] Furthermore, the lifting platform includes a lead screw slide, a drive motor, a power supply, and a scale. The lead screw slide is mounted on the base, and the mounting base, drive motor, power supply, and scale are mounted on the lead screw slide. The drive motor is connected to the lead screw slide and drives the mounting base to perform lifting and lowering movements through the lead screw slide. The power supply is electrically connected to the drive motor, the horizontal laser emitter, the laser rangefinder, and the control system.

[0009] Furthermore, the manual adjustment platform includes a fixed plate, an adjustment plate, a height adjustment bolt, and a spirit level. The fixed plate is detachably connected to the tripod, the adjustment plate is connected to the fixed plate via the height adjustment bolt, the spirit level is located on the adjustment plate, and the lifting platform is located on the adjustment plate.

[0010] Furthermore, the adjustment plate is provided with a turntable, and the lifting platform is movably mounted on the adjustment plate via the turntable.

[0014] Furthermore, the automatic leveling seat is a gyroscope, and the reflector is a laser reflector.

[0015] A method for using an automated elevation transfer and elevation setting-out measuring device, characterized by comprising the following steps:

[0016] S1, Determine the elevation benchmark: First, measure the plane elevation of the reflector, install the reflector at the control point on the first floor inside the building, and use the plane elevation of the reflector as the elevation benchmark.

[0017] S2, Install the instrument: After installing the manual adjustment platform on the tripod, install the height transducer on the manual adjustment platform, and then place the installed equipment at the wire hole of the floor to be measured inside the building, so that the tripod is aligned with the wire hole, adjust the height of the tripod and adjust the level of the manual adjustment platform.

[0018] S3, Equipment Leveling: Turn on the power switch to power on the equipment, the host performs a self-test, the lifting platform automatically initializes, and manually unlock the automatic leveling seat to keep the horizontal laser emitter level.

The operator marks a one-meter line on the building wall and column according to the projected horizontal laser line, and rotates the height transmitter to mark the line 360°.

[0024] S9, Equipment Transfer: After the current floor's marking line construction is completed, manually lock the automatic leveling seat and turn off the power, then transfer the installed equipment to the next floor for construction.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] like Figure 1 , 2As shown, an automated elevation transfer and elevation measurement device is used for measuring building elevation. It includes a height transmitter 1, a base 2, and a reflector 3. The reflector 3 is set at the control point on the first floor inside the building. The base 2 is set at the line-laying hole of the floor to be measured inside the building. The height transmitter 1 is set on the base 2.

[0039] like Figure 2 , 3 As shown in Figure 4, the height transmitter 1 includes a main unit 11 and a lifting platform 12. The base 2 includes a tripod 21 and a manual adjustment platform 22. The tripod 21 is set at the wire-laying hole of the floor to be measured, and the manual adjustment platform 22 is set on the tripod 21. The lifting platform 12 is set on the manual adjustment platform 22, and the main unit 11 is movably set in the lifting platform 12. The main unit 11 and the reflector 3 are arranged vertically and vertically respectively.

[0040] This invention utilizes a laser rangefinder 112 to measure the current elevation, performs precise height calculation and automatic adjustment, and then projects a one-meter line onto the current floor using a horizontal laser emitter 111. This achieves automated and intelligent operation for elevation transfer and horizontal elevation projection. In practice, the laser rangefinder 112 and reflector 3 work together to automatically measure distance. After measurement, the height of the main unit 11 is automatically calculated and adjusted. Once in position, the horizontal laser emitter 111 precisely projects a one-meter horizontal laser line, which can then be manually marked. Because the horizontal laser emitter 111 and laser rangefinder 112 are integrated into the main unit 11, and their distance is fixed, the laser line emitted by the horizontal laser emitter 111 after precise distance measurement and automatic correction by the laser rangefinder 112 represents the one-meter line for the current floor. Automatic distance measurement and correction ensure accurate height measurement, and automation reduces procedures, improves construction efficiency, and enables single-person operation.

[0041] like Figure 5 , 6As shown, the host 11 further includes a horizontal laser emitter 111, a laser rangefinder 112, a mounting base 113, an automatic leveling seat 114, and a control system 115. The mounting base 113 is mounted on the lifting platform 12 as a mounting foundation. The laser rangefinder 112, the automatic leveling seat 114, and the control system 115 are mounted on the mounting base 113. The laser rangefinder 112 and the reflector 3 are arranged vertically and vertically to cooperate in measuring distance. The automatic leveling seat 114 is used for adaptive balance and for automatically leveling the horizontal laser emitter 111 with small amplitude. The horizontal laser emitter 111 is mounted on the automatic leveling seat 114. The control system 115 is electrically connected to the horizontal laser emitter 111, the laser rangefinder 112, and the lifting platform 12 to realize the automatic control of the host.

[0042] like Figure 8 As shown, the lifting platform 12 further includes a lead screw slide 121, a drive motor 122, a power supply 123, and a scale. The lead screw slide 121 is mounted on the base 2. The mounting base 113, drive motor 122, power supply 123, and scale are mounted on the lead screw slide 121. The drive motor 122 is connected to the lead screw slide 121. The drive motor 122 drives the mounting base 113 to move up and down on the lead screw slide 121 through the lead screw slide 121. The power supply 123 is electrically connected to the drive motor 122, the horizontal laser emitter 111, the laser rangefinder 112, and the control system 115, providing power to the above components.

[0043] Furthermore, the scale is set on the lead screw slide 121, vertically positioned and located on one side of the main unit 11. When the main unit 11 performs automatic correction, the operator checks the automatic correction through the "correction value" on the display to confirm whether there is any problem with the automatic correction being incomplete or incorrect. If there is a problem, manual intervention is required to ensure the normal operation of the equipment and the correct adjustment of parameters.

[0044] Preferably, the scale is a vertically set scale.

[0045] like Figure 7As shown, the manual adjustment platform 22 further includes a fixed plate 221, an adjustment plate 222, a height adjustment bolt 223, and a spirit level 224. The fixed plate 221 is detachably connected to the tripod 21. The adjustment plate 222 is connected to the fixed plate 221 via the height adjustment bolt 223. The level of the adjustment plate 222 is adjusted by adjusting the height adjustment bolt 223. This adjustment range is relatively large, but the accuracy is poor. It is used in conjunction with the automatic leveling seat 114 with a small adjustment range but high accuracy to accurately adjust the horizontal laser emitter 111 and ensure the level of the horizontal laser emitter 111. The spirit level 224 is set on the adjustment plate 222 and is used for manual adjustment calibration. The lifting platform 12 is set on the adjustment plate 222.

[0046] Furthermore, the adjustment plate 222 is provided with a turntable, and the lifting platform 12 is movably mounted on the adjustment plate 222 via the turntable. The turntable enables the lifting platform 12 to rotate 360° around the axis, thereby projecting the horizontal laser line completely onto the wall column.

[0047] Furthermore, the control system 115 includes a main controller, a display, and control buttons. The main controller is used to receive data and calculate, and then output control parameters to each automatic component. The control buttons include switches, distance measuring, and correction.

[0048] Furthermore, both the lead screw slide 121 and the manual adjustment platform 22 are provided with wire feeding clearance holes.

[0049] Furthermore, the automatic leveling seat 114 is provided with a manual locking structure, which is an automatic mechanical lock used to lock the automatic leveling seat 114. It is unlocked in the working state and locked in the moving state.

[0050] Furthermore, the automatic leveling seat 114 is a gyroscope, and the reflector 3 is a laser reflector.

[0051] like Figure 1 As shown, a method for using an automated elevation transfer and elevation setting-out measuring device includes the following steps:

[0052] S1, Determine the elevation benchmark: First, measure the plane elevation of reflector 3, install reflector 3 at the control point on the first floor inside the building, and use the plane elevation of reflector 3 as the elevation benchmark.

[0053] S2, Install the instrument: After installing the manual adjustment platform 22 on the tripod 21, install the height transmitter 1 on the manual adjustment platform 22, and then place the installed equipment at the wire hole of the floor to be measured inside the building, so that the tripod 21 is aligned with the wire hole, adjust the height of the tripod 21 and adjust the level of the manual adjustment platform 22.

[0054] S3, Equipment Leveling: Turn on the power switch to power on the equipment. The host 11 performs a self-test, the lifting platform 12 initializes automatically, and the lock of the automatic leveling seat 114 is manually released so that the horizontal laser emitter 111 remains horizontal.

[0055] S4, Input Values: Manually input the parameters of the reference elevation and design elevation in the control system 115;

[0056] S5, Adjust offset: Start the laser rangefinder 112 to observe whether the laser point is aligned with the reflector 3, and manually adjust the manual adjustment platform 22 to align the laser point with the center of the reflector.

[0057] S6, Automatic Distance Measurement: Click the distance measurement button, and the laser rangefinder 112 emits a laser to the reflector 3 to measure the distance. After calculation by the control system 115, the display shows "distance value", "current elevation", and "correction value". "Distance value" is the height difference between the center of the horizontal laser emitter 111 and the surface of the reflector 3. "Current elevation" is the elevation value of the horizontal laser emitter 111. "Correction value" is the difference between "current elevation" and "design elevation". "Correction value" is distinguished by positive and negative values. Positive values ​​are corrected downwards, and negative values ​​are corrected upwards.

[0058] S7, Automatic Correction: Clicking the correction button will drive the motor 122 to control the host 11 to rise and fall on the lifting platform 12. The rising and falling height is the value of the "correction value", and the operation will be repeated once to accurately adjust the elevation error.

[0059] S8, Elevation Projection: After automatic correction, the horizontal laser emitter 111 emits a horizontal laser line and projects it onto the wall and column of the floor to be measured. The operator marks a one-meter line on the building wall and column according to the projected horizontal laser line, and rotates the height transmitter 1 to mark the line 360°.

[0060] S9, Equipment Transfer: After the current floor's marking line construction is completed, manually lock the automatic leveling seat 114 and turn off the power, then transfer the installed equipment to the next floor for construction.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
