Description

Technical Field

[0001] The present invention relates to the technical field of laser detection, and particularly to a laser detection device for measuring the inclination angle of a building. Background Art

[0002] In the field of construction engineering, when measuring the flatness of walls and ceilings, a laser rangefinder is usually a favored measuring tool. The laser rangefinder does not need to be in direct contact with the surface of the object to be measured, which not only avoids the damage such as scratching and bumping that traditional measuring tools may cause to the wall surface, but also can quickly obtain measurement data, greatly shortening the measurement time. Its measurement accuracy is extremely high, and it can accurately perceive subtle height differences, thus providing a reliable basis for the flatness evaluation of walls and ceilings.

[0003] In the modern construction engineering field, laser detection devices have been widely used in the detection of the flatness of walls and ceilings due to their high detection capabilities. However, when measuring the internal corners of a room, the measuring personnel often need to frequently reposition and calibrate the device manually, and adjust the position of the laser detection device multiple times. This not only causes the device to deviate, resulting in large errors in the detection results, but also significantly increases the time and labor costs, seriously slowing down the overall measurement progress and greatly reducing the measurement efficiency. Therefore, we propose a laser detection device for measuring the inclination angle of a building. Summary of the Invention

A fixing frame is arranged on the top of the base. On one side of the fixing frame away from the base, there are two laser detector bodies for detecting the inclination angle. An adjusting mechanism for driving the two laser detector bodies to flip is arranged between the fixing frame and the two laser detector bodies. The adjusting mechanism can drive the laser detector bodies to flip horizontally or vertically, so that the two laser detector bodies are kept relatively parallel or perpendicular. And there are two positioning mechanisms for protecting the laser detector bodies arranged between the two laser detector bodies and the adjusting mechanism. The positioning mechanism can drive the laser detector bodies to rotate, so that the laser detector bodies and the adjusting mechanism are kept in a relatively horizontal state or a relatively vertical state. When it is necessary to measure the angle of the plane by the laser detector body, the adjusting mechanism drives the two positioning mechanisms to be in a parallel state with each other, and the two positioning mechanisms drive the two laser detector bodies to be in a parallel state with each other, and the plane angle is measured by using the laser detector body. When it is necessary to measure the internal angle or external angle by the laser detector body, the adjusting mechanism drives the two positioning mechanisms to be in a perpendicular state with each other, and the two positioning mechanisms drive the two laser detector bodies to be in a perpendicular state with each other, so as to measure the internal angle or external angle.

The lifting seat 514 drives the protection frame 516 to lift and lower, separating the protection frame 516 from the emitting end of the laser detector body 3.

[0027] Working principle: When it is necessary to detect the internal and external corners, rotate the threaded rod 411. The threaded rod 411 cooperates with the threaded sleeve 412 to drive the threaded sleeve 412 to lift and lower. The threaded sleeve 412 drives the fixed plate 501 to rotate around the outside of the positioning rod 410, so that the fixed plate 501 is kept in a relatively parallel state with the horizontal plane. Rotate the adjustment knob 406. The adjustment knob 406 drives the adjustment rod 405 to rotate clockwise. The adjustment rod 405 drives the worm 404 to rotate clockwise. The worm 404 drives the engaged worm gear 403 to rotate clockwise by 90 degrees. The worm gear 403 drives the rotating rod 402 to rotate clockwise by 90 degrees. The rotating rod 402 drives the main support rod 407 to rotate clockwise by 90 degrees. The main support rod 407 drives the fixed positioning frame 409 fixed thereto to rotate clockwise by 90 degrees around the axis of the rotating rod 402. The positioning frame 409 drives the fixed positioning rod 410 fixed thereto to rotate clockwise by 90 degrees around the axis of the rotating rod 402. The positioning rod 410 drives the fixed plate 501 to rotate clockwise by 90 degrees around the axis of the rotating rod 402; The fixed plate 501 rotates 90 degrees clockwise around the axis of the rotating rod 402 through the pressure rod 508. The pressure rod 508 drives the rotating shaft 509 to rotate 90 degrees around the axis of the positioning rod 410. The rotating shaft 509 drives the laser detector body 3 to rotate 90 degrees around the axis of the rotating rod 402 through the mounting block 510. The telescopic end of the electric push rod 505 pushes the transmission block 504 to move. The transmission block 504 drives the slider 503 to move along the outside of the guide rail 502. Moreover, the transmission block 504 can also drive the moving rod 507 to move. The moving rod 507 slides along the transmission groove. The transmission groove limits the moving rod 507, so that the moving rod 507 drives the flipping block 506 to rotate 90 degrees around the axis of the rotating shaft 509. The rotating shaft 509 drives the laser detector body 3 to rotate 90 degrees around the axis of the rotating shaft 509 through the mounting block 510, so that the laser detector body 3 changes from a relatively vertical state to a relatively horizontal state with the fixed plate 501, and the laser detector body 3 maintains a relatively parallel state with the horizontal plane; Meanwhile, the slider 503 drives the insertion rod 511 to move. The insertion rod 511 drives the power rod 512 to move. The power rod 512 drives the limit frame 513 to move. The limit frame 513 drives the lifting rod 515 to move through the card slot. The lifting rod 515 drives the lifting seat 514 to move. The lifting seat 514 drives the limit slot to move along the inside of the inclined slot, so that the limit rod drives the lifting seat 514 to lift and lower. The lifting seat 514 drives the protection frame 516 to lift and lower, separating the protection frame 516 from the emitting end of the laser detector body 3.
