[0017] The present invention also discloses a surveying method for a building construction surveying device, which specifically includes the following steps:

[0018] Step 1: According to the range of the area to be measured, select a sliding sleeve and a straight plate with appropriate lengths. Then, connect the sliding sleeve to the sleeve through the connection of the stud and the rotating plate. Next, place the two sleeves on both side edges of the measurement area respectively, and make the sleeve fit seamlessly with the measurement area by pressing through the rubber ring. Then, rotate the worm so that the worm gear drives the gear to rotate through the cross bar, so that the rack pulls the circular plate into the sleeve, so as to fix the sleeve through the action of air pressure difference.

Then, by rotating the lead screw, one side slider drives one end of the corresponding side sliding sleeve to move, so that the distance values between the two side sliding sleeves and the measurement area are the same. Then, observe the angle indicated by the pointer again to obtain the inclination angle of the correct measurement area. Advantages

[0021] The present invention provides a building construction surveying and mapping device and its surveying and mapping method. Compared with the prior art, it has the following advantages:

[0022] (1) By setting up a measuring mechanism, the rotating plate rotates along the fixed wheel, and through synchronous positioning on both sides, the slope of the corridor can be measured quickly and simply. At the same time, through the setting of the scale plate, the distance can also be measured, and through the movement of the slider, positioning adjustment is carried out to reduce the difficulty of calibration, thereby not only improving the efficiency of surveying and mapping but also expanding the scope of use.

[0023] (2) By setting up a calibration component, with the action of the gravity seat, rotating sleeve and vertical rod, the laser rangefinder always faces the surface of the staircase downward, facilitating distance measurement, thus facilitating the calibration of angle measurement. At the same time, with the cooperation of the rotating sleeve and the rotating bar, the stability during movement can be improved.

[0024] (3) By setting up a moving unit, with the flat motor, rollers and synchronous belt, the laser rangefinder can be driven to move by the sliding frame, so as to measure the distance at both ends of the measurement. At the same time, with the cooperation of the spring rod and the rotating frame, it is convenient for the rollers to move coherently inside the clamping grooves on the straight plate and the sliding sleeve, thus avoiding affecting the measurement of the laser rangefinder.

[0025] (4) By setting up a fixing component, with the action of the gear and the rack, the circular plate can be pulled into the sleeve, and through the air pressure difference on both sides of the circular plate, the sleeve is adsorbed and fixed on the surface of the staircase. At the same time, with the locking action of the worm gear and the worm, the stability of the sleeve fixation is improved.

[0026] (5) By setting up an air supplement unit, turning the bolt can drive the sliding column to move, and through the movement of the sliding column, its shielding of the air hole is controlled to be disengaged, so as to supplement air to one side of the circular plate to balance the air pressure on both sides of the circular plate, facilitating the quick disassembly of the sleeve.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-8 , the present invention provides a technical solution: a building construction surveying and mapping device:

[0038] Embodiment 1: It includes two sleeves 1. A measuring mechanism is arranged between the outer surfaces of the two sleeves 1. The measuring mechanism includes a straight plate 2. The straight plate 2 can be made of an aluminum alloy square tube to ensure the hardness, wear resistance and corrosion resistance of the device. The straight plate 2 is arranged between the outer surfaces of the two sleeves 1. Slide sleeves 3 are slidably connected to both sides of the outer surface of the straight plate 2. The slide sleeves 3 are made of the same material as the straight plate 2 and are provided in multiple groups with different sizes from the straight plate 2 to facilitate measurement by providing different length ranges. Clamping grooves 6 are formed on the outer surfaces of the slide sleeves 3 and the straight plate 2. Two abutting blocks 7 are arranged inside the slide sleeve 3. The mutual abutment between the abutting blocks 7 can prevent the disconnection of the straight plate 2. At the same time, there is an interference fit connection between the abutting blocks 7 fixed inside the slide sleeve 3 and the clamping grooves 6 on the straight plate 2 to maintain the stability of the straight plate 2 during measurement. The outer surface of one side of the abutting block 7 is fixedly connected to the inside of the slide sleeve 3, and the outer surface of the other side of the abutting block 7 is fixedly connected to the inside of the clamping groove 6 on the straight plate 2. A stud 8 is fixedly connected to the outer surface of the slide sleeve 3. The size of the stud 8 is standardized to improve the compatibility. A rotating plate 9 is threadedly connected through the outer surface of the stud 8. The connection between the stud 8 and the rotating plate 9 facilitates the replacement of combinations of slide sleeves 3 and straight plates 2 with different sizes. A fixed wheel 10 is rotatably connected through the body of the rotating plate 9. The fixed wheel 10 plays a role of limiting and supporting. A fixed column 11 is fixedly connected to the outer surface of the fixed wheel 10. An arc strip 12 is fixedly embedded on the outer surface of the rotating plate 9. Two arc strips 12 are radially symmetric and fit together. At the same time, an angular measurement value of 180° is set on the surface of the arc strip 12. A pointer 14 is fixedly connected to the outer surface of the fixed wheel 10. By pointing to the angular value on the arc strip 12, the pointer 14 can facilitate the quick acquisition of the measurement value. A scale plate 15 is fixedly embedded on the outer surface of the straight plate 2. The distance measurement value can be known on the scale plate 15, and the zero scale of the measurement value is set at the center of the scale plate 15, and the values increase sequentially from the center to both sides.

[0039] A sliding groove 16 is fixedly connected to the outer surface of the sleeve 1. Equidistant lines can be set on the surface of the sliding groove 16. The size between the equidistant lines is set according to actual needs. A slider 17 is slidably connected inside the sliding groove 16. The slider 17 moves along the equidistant lines to facilitate quick and accurate positioning. The outer surface of the slider 17 is fixedly connected to one end of the fixed column 11. A lead screw 13 is threadedly connected through the body of the slider 17. A measure convenient for turning a knob can be set at one end of the lead screw 13. One end of the lead screw 13 is rotatably connected through the body of the sliding groove 16 and extends to the outside of the sliding groove 16.

[0040] By setting the measuring mechanism, by rotating the rotating plate 9 along the fixed wheel 10 and through synchronous positioning on both sides, the slope of the corridor can be quickly and simply measured. At the same time, through the setting of the scale plate 15, the distance can also be measured, and through the movement of the slider 17, positioning adjustment is carried out to reduce the difficulty of calibration, thereby not only improving the efficiency of surveying and mapping, but also expanding the scope of use.

[0041] Example 2: A calibration component 4 is arranged outside the sliding sleeve 3. The calibration component 4 includes a bone rod 41. A rotating sleeve 42 is rotatably connected to the outer surface of the bone rod 41. A vertical rod 43 is fixedly connected to the outer surface of the rotating sleeve 42. A gravity seat 44 is fixedly connected to one end of the vertical rod 43. The gravity seat 44 is made of a material with a relatively large density to lower the center so that the vertical rod 43 is always vertically downward. A laser rangefinder 45 is fixedly connected to the outer surface of the gravity seat 44. The laser rangefinder 45 is coaxially arranged with the vertical rod 43 and is electrically connected to an external control circuit.

[0042] Two fixing frames 47 are arranged outside the bone rod 41. A rotating bar 48 is rotatably connected to the outer surface of one side fixing frame 47. The surface of the rotating bar 48 can be set to be rough. Through contact with the rotating sleeve 42, the laser rangefinder 45 is fixed by the friction effect. The outer surface of the rotating bar 48 is movably connected to the outer surface of the rotating sleeve 42. The outer surface of the rotating bar 48 is movably connected to the outer surface of the other side fixing frame 47. The rotating bar 48 and the other side fixing frame 47 can be connected by interference fit to improve the stability of itself and the laser rangefinder 45.

[0043] By setting the calibration component 4, with the functions of the gravity seat 44, the rotating sleeve 42 and the vertical rod 43, the laser rangefinder 45 always faces the surface of the step ladder downward, which is convenient for distance measurement, thus facilitating the calibration of angle measurement. At the same time, with the cooperation of the rotating sleeve 42 and the rotating bar 48, the stability during movement can be improved.

[0044] Example 3: A moving unit 46 is arranged outside the laser rangefinder 45. The moving unit 46 includes a sliding frame 461. The size of the sliding frame 461 is larger than that of the sliding sleeve 3, which plays a role of connection and support. The sliding frame 461 is sleeved outside the sliding sleeve 3. The outer surface of the sliding frame 461 is fixedly connected to the outer surfaces of the two fixing frames 47. The outer surface of the sliding frame 461 is fixedly connected to one end of the bone rod 41. A spring rod 462 is fixedly connected inside the sliding frame 461. The telescopic movement of the output end of the spring rod 462 can adapt to the distance difference between the straight plate 2 and the clamping groove 6 on the sliding sleeve 3. One end of the spring rod 462 is rotatably connected to a rotating frame 463. A connecting plate 464 is fixedly connected to the outer surface of the rotating frame 463. Two rollers 465 are arranged outside the connecting plate 464. The outer surfaces of the two rollers 465 are both movably connected to the inside of the clamping groove 6.

[0045] Both ends of the roller 465 are rotatably connected with a fixed plate 466, and the outer surfaces of the fixed plates 466 on both sides are fixedly connected to the outer surface of the connecting plate 464. The outer surfaces of the rollers 465 on both sides are connected through a synchronous belt 467. The synchronous belt 467 can facilitate the synchronous movement of the rollers 465 on both sides, and the distance between the synchronous belt 467 and the outer periphery of the roller 465 is set to be large, which can avoid affecting the movement of the roller 465 when changing positions between the clamping grooves 6. The outer surface of the fixed plate 466 on one side is fixedly connected with a flat motor 468. The flat motor 468 is made of a servo motor and is electrically connected to an external control circuit. The output end of the flat motor 468 is fixedly connected to one end of the roller 465 on one side through a coupling.

[0046] By setting up the moving unit 46, using the flat motor 468, the roller 465 and the synchronous belt 467, the laser rangefinder 45 can be moved through the slide frame 461, so that the distance of the two ends of the measurement can be measured. At the same time, the cooperation of the spring rod 462 and the rotating frame 463 can facilitate the roller 465 to move continuously inside the clamping groove 6 on the straight plate 2 and the sliding sleeve 3, thereby avoiding affecting the measurement of the laser rangefinder 45.

[0047] Embodiment 4: A fixing component 5 is arranged on the outside of the sliding sleeve 3, and the fixing component 5 includes a rubber ring 51. The rubber ring 51 can facilitate the seamless fitting of the sleeve 1 and the surface of the step or other measuring area surfaces due to its own sealing and elasticity. The rubber ring 51 is arranged at one end of the sleeve 1, and a circular plate 52 is movably connected inside the rubber ring 51. The circular plate 52 can be made of an existing piston plate. The outer surface of the circular plate 52 is movably connected to the inside of the sleeve 1, and a rack 54 is fixedly connected to the outer surface of the circular plate 52.

The sliding rod 55 serves to limit and guide the movement of the rack 54, and one end of the sliding rod 55 is fixedly connected to the inside of the sleeve 1.

The self-locking effect of the worm 59 and the worm wheel 58 can improve the stability of the sleeve 1 when it is fixed, and one end of the worm 59 is provided with a measure for facilitating the turning of the knob, and one end of the worm 59 is rotatably connected to the body of the sleeve 1 and extends to the outside of the sleeve 1.

[0049] By setting up the fixing component 5, the circular plate 52 can be pulled into the sleeve 1 by utilizing the action of the gear 56 and the rack 54, and the sleeve 1 can be adsorbed and fixed on the surface of the step by the air pressure difference on both sides of the circular plate 52. At the same time, the locking action of the worm wheel 58 and the worm 59 can be utilized to improve the stability of the fixing of the sleeve 1.

[0050] Embodiment 5: An air supplement unit 53 is provided outside the circular plate 52. The air supplement unit 53 includes a fixed sleeve 531. The inside of the fixed sleeve 531 is in through communication with the inside of the sleeve 1. The body of the fixed sleeve 531 is provided with a through air hole 532. The air hole 532 can facilitate the supplementation of external gas into the inside of the sleeve 1, so as to disassemble the sleeve 1 by balancing the air pressure on both sides of the circular plate 52. A filter screen 533 is arranged inside the air hole 532. The filter screen 533 can facilitate the filtration of dust and impurities in the outside world. The body of the fixed sleeve 531 is threadedly connected through a bolt 534. One end of the bolt 534 is fixedly connected with a sliding column 535. The sliding column 535 is made of a material with compressive resistance, wear resistance and good sealing performance. The outer surface of the sliding column 535 is movably connected with the inside of the fixed sleeve 531.

[0051] By providing the air supplement unit 53, turning the bolt 534 can drive the movement of the sliding column 535, and through the movement of the sliding column 535, it can be controlled to disengage from the shielding of the air hole 532, so as to supplement air to one side of the circular plate 52 to balance the air pressure on both sides of the circular plate 52, so as to facilitate the quick disassembly of the sleeve 1.

[0052] The present invention also discloses a surveying method for a building construction surveying device, which specifically includes the following steps:

[0053] Step 1: According to the range of the area to be measured, select a sliding sleeve 3 and a straight plate 2 with appropriate lengths, sleeved the sliding frame 461 outside the sliding sleeve 3, and make the roller 465 located inside the clamping groove 6 of the sliding sleeve 3. Then connect the sliding sleeve 3 with the sleeve 1 through the connection of the stud 8 and the rotating plate 9. Then place the two sleeves 1 on both side edges of the measurement area respectively, and press to make the sleeve 1 fit seamlessly with the measurement area by using the rubber ring 51. Then rotate the worm 59 so that the worm gear 58 drives the gear 56 to rotate through the cross bar 57, so that the rack 54 pulls the circular plate 52 into the inside of the sleeve 1, so as to fix the sleeve 1 through the action of air pressure difference. When disassembling the sleeve 1, turn the bolt 534 to make the sliding column 535 move inside the fixed sleeve 531, and through the sliding column 535 disengaging from the shielding of the air hole 532, the outside air enters one side of the inside of the sleeve 1 through the air hole 532 and the fixed sleeve 531, so as to balance the air pressure on both sides of the circular plate 52, eliminate the adsorption and fixing effect, and complete the disassembly of the sleeve 1;

[0054] Step 2: After the two sleeves 1 are fixed, observe the extension amount of the scale plate 15 on the straight plate 2, and cooperate with the fixed dimensions of the sliding sleeve 3, etc., the length of the measurement area can be measured. At the same time, according to the angle unit pointed by the pointer 14 on the arc bar 12, the angle value of the measurement area can be measured;

[0055] Step 3: When calibrating the measurement result, through the actions of the vertical rod 43, the gravity seat 44, and the rotating sleeve 42, the laser rangefinder 45 is vertically oriented towards the surface of the staircase in the measurement area. Then, rotate the rotating bar 48 so that it is connected to the other fixed frame 47 through interference fit, and at the same time, through contact with the rotating sleeve 42, the fixation of itself and the laser rangefinder 45 is completed. Then, the flat motor 468 drives one side roller 465 to move inside the clamping groove 6, and through the transmission of the synchronous belt 467, the other side roller 465 moves synchronously, so that the sliding frame 461 drives the laser rangefinder 45 to move along the sliding sleeve 3 and the straight plate 2. When the roller 465 changes its position inside the clamping groove 6 on the straight plate 2 and the sliding sleeve 3, through the telescoping of the output end of the spring rod 462 and the rotation of the rotating frame 463, one side roller 465 makes contact through inclination, and the roller 465 realizes the conversion inside the clamping grooves 6 at different positions, and continuously measures the distance between itself and the measurement area through the laser rangefinder 45. If there is a displacement difference between the beginning and the end of the measurement, that is, a triangular error is formed, representing an incorrect angle value shown above. Then, rotate the lead screw 13 so that one side slider 17 drives one end of the corresponding side sliding sleeve 3 to move, so that the distance values between the two side sliding sleeves 3 and the measurement area are the same. Then, observe the angle indicated by the pointer 14 again, and the inclination angle of the correct measurement area can be obtained.
