Referring to Figures 1-4, a detection device includes a calibration base 1, the shape of the calibration base 1 is a cuboid, when the levelness detection of the plane to be detected is performed, the calibration base 1 is placed at a corner of the plane to be detected, and the calibration base 1 The long side and wide side of the calibration base 1 are respectively aligned with the long side and the broad side of the plane to be detected. The upper end surface of the calibration base 1 is fixedly connected with a pillar 2, and the end of the pillar 2 away from the calibration base 1 is fixedly connected with a slider 3. A self-stabilizing table 4 is slidably connected to one side wall of the slider 3 away from the pillar 2, and the self-stabilizing table 4 is a hemispherical table.

The bottom side wall of the self-stabilizing table 4 is provided with a limit groove 5, the slider 3 is slidably connected in the limit groove 5, and a fixing ring 6 is fixedly connected to the center of one side wall of the self-stabilizing table 4 away from the slider 3, The inner side wall of the fixing ring 6 is fixedly connected with a laser light 7, and the laser light 7 and the limit groove 5 are in the same plane. When the plane to be detected has an inclination angle between the long side direction of the calibration base 1 and the horizontal plane, the self-stable operation is performed. The table 4 can automatically rotate around the side wall of the slider 3 away from the pillar 2 by its own gravity, so that after the self-stabilizing table 4 is stabilized, the central axis of the self-stabilizing table 4 along the direction of the laser light 7 is parallel to the horizontal plane, That is, the laser light emitted by the laser lamp 7 is parallel to the horizontal plane.

The center of gravity of the laser light 7 is directly above the center of the upper end face of the self-stabilizing table 4, and the center of gravity of the laser light 7 is coincident with the spherical center of the self-stabilizing table 4, so as to ensure that no matter what the inclined state of the plane to be measured is, When the self-stabilizing table 4 is self-stabilizing, its central axis along the direction of the laser light 7 can be parallel to the horizontal plane, so the laser light emitted by the laser light 7 can be used as the horizontal reference line, so as to detect whether the plane to be detected is horizontal, and calibrate the base 1 Two fixed rods 8 are symmetrically and fixedly connected on the upper end surface of the .

A mounting ring 9 is fixedly connected to one end of the two fixing rods 8 away from the calibration base 1. A rotating shaft 10 is rotatably connected to the mounting ring 9. A dial 11 is arranged between the two rotating shafts 10, and the laser emitting end of the laser lamp 7 is facing The center of the dial 11 is set. When the plane to be measured is in a horizontal state, the calibration base 1 is also in a horizontal state. At this time, the automatic workbench 4 is in a horizontal state, and the laser light emitted by the laser lamp 7 is irradiated at the center of the dial 11. Two sliding grooves 12 are symmetrically arranged on the outer side wall of the dial 11 , and a movable plate 13 is slidably connected in the two sliding grooves 12 .

The movable plate 13 is arranged in an arc shape, and the two movable plates 13 arranged in an arc shape can support and limit the dial 11. The movable plate 13 is fixedly connected to one end of the rotating shaft 10 close to the dial 11, and the dial 11 A counterweight 14 is fixedly connected to the bottom end of the movable plate 13. Since the movable plate 13 is slidably connected in the chute 12, the dial 11 can rotate along the direction of the movable plate 13. Since one end of the rotating shaft 10 is fixedly connected to the movable plate 13, the rotating shaft The other end of 10 is rotatably connected in the mounting ring 9, so the dial 11 can also rotate around the rotating shaft 10, so that the gravity of the counterweight 14 can be used, so that the plane of the dial 11 is vertical and horizontal.

Therefore, when the plane to be detected has an inclination angle between the width direction of the calibration base 1 and the horizontal plane, the dial 11 will rotate in the direction of the movable plate 13 under the gravity of the counterweight 14, and the rotation angle is equal to the plane to be detected. To calibrate the inclination angle between the width direction of the base 1 and the horizontal plane, a first scale stripe 15 and a second scale stripe 16 are respectively provided on one side wall of the dial 11 close to the laser light 7. The first scale stripe 15 is arranged close to the counterweight 14 , and the second scale strip 16 is arranged close to the mounting ring 9 .

Under the action of self-stabilization, it is kept parallel to the horizontal plane, and the dial 11 can be kept vertical to the horizontal plane under the action of the gravity of the configuration block 14. Therefore, the scale of the first scale stripe 15 corresponding to the spot of the laser on the dial 11 corresponds to The size of the inclination angle between the plane to be detected in the longitudinal direction of the calibration base 1 and the horizontal plane is determined.

The scale of the second scale stripe 16 pointed to by the pointer 17 corresponds to the inclination angle between the plane to be detected in the direction of the wide side of the calibration base 1 and the horizontal plane, the long side and wide side of the calibration base 1 and the long side of the plane to be detected It is aligned with the broad side, so the detection device can not only conveniently detect whether a plane is horizontal, but also measure the inclination angle between the plane and the horizontal plane in the direction of its own long side and wide side, so that the length of the plane can be measured by measuring the length of the plane. Side and broadside lengths, calculate the height of the spacer required to make the plane parallel.

In the present invention, when the user uses the device, when performing levelness detection on the plane to be detected, the calibration base 1 is first placed at a corner of the plane to be detected, and then the long side and the wide side of the calibration base 1 are respectively aligned with the level to be detected. The long sides and wide sides of the plane are aligned one by one, and then the laser light 7 is turned on. If the laser light point of the laser light 7 on the dial 11 is facing the center of the dial 11, it means that the plane to be detected is horizontal. If it is not aligned, it means that the plane to be detected is inclined;

At this time, the scale of the first scale stripe 15 corresponding to the spot of the laser on the dial 11 is the inclination angle between the plane to be detected in the longitudinal direction and the horizontal plane, and the second scale stripe 16 pointed by the pointer 17 The scale corresponding to the inclination angle of the plane to be detected in the direction of the wide side of the calibration base 1 and the horizontal plane, so the detection device can not only conveniently detect whether a plane is horizontal, but also can detect whether the plane is horizontal or not. The inclination angle between the top and the horizontal plane is measured, so that the height of the pad required to make the plane parallel can be calculated by measuring the length of the long and broad sides of the plane.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
