[0030] Example

[0031] The specific implementation of the utility model is as follows Figures 1 to 5 As shown, a multifunctional indoor building measuring instrument includes a translation distance measuring mechanism 6, which is connected to a mounting frame 1 via a rotating support 5. The mounting frame 1 is provided with a plurality of first distance measuring sensors arranged along a straight line, and the arrangement direction of each first distance measuring sensor is perpendicular to the movement direction of the translation distance measuring mechanism 6. The mounting frame 1 is also provided with an angle measuring instrument. The first distance measuring sensors, the translation distance measuring mechanism 6 and the angle measuring instrument are all electrically connected to a controller.

[0032] In this embodiment, the first distance measuring sensor is a first laser distance sensor 2, and the angle measuring instrument is a gyroscope 3. In addition, the first distance measuring sensor may also be a distance sensor in other forms.

[0033] A plurality of first laser distance sensors 2 arranged in a straight line form a ranging scanning array. The arrangement direction of each first laser distance sensor 2 in the ranging scanning array is perpendicular to the translation direction of the ranging scanning array, and the orientation of the first laser distance sensors 2 is perpendicular to the translation direction of the ranging scanning array.

[0034] The rotation axis of the rotating support 5 can be bolted, and its angle can be locked by tightening the bolt and nut. The center line of the rotation axis of the rotating support 5 is parallel to the translation direction of the ranging scanning array.

[0035] The mounting frame 1 is provided with a sensor guard plate 4, which is located on both sides of the first laser distance sensor 2. In this embodiment, a strip of U-shaped channel steel is installed on the mounting frame 1, and the first laser distance sensor 2 is located on the inner side of the U-shaped channel steel. The two side walls of the U-shaped channel steel constitute the sensor guard plate 4.

[0036] In this embodiment, the mounting frame 1 adopts a straight strip profile structure. The mounting frame 1 includes at least two mounting frame modules 11 that can be folded into each other, and each mounting frame module 11 is provided with a first laser distance sensor 2 and a gyroscope 3. In this embodiment, the mounting frame 1 is composed of two mounting frame modules 11, one end of which is rotatably connected to the translation distance measurement mechanism 6 via a rotating support 5. One side of the adjacent mounting frame modules 11 is hinged by a hinge 12, and the other side is connected by a locking plate 13. Specifically, both ends of the locking plate 13 are provided with through holes for screws to pass through. The screws at both ends respectively pass through the through holes at both ends of the locking plate 13 and are threadedly connected to the corresponding mounting frame modules 11, thereby locking the relative positions of the adjacent mounting frame modules 11.

[0037] The first laser distance sensors 2 are oriented in parallel and are arranged at equal intervals. The orientation of the first laser distance sensors 2 is perpendicular to the arrangement direction of the first laser distance sensors 2 .

[0038] The end of the mounting frame 1 away from the translation distance measuring mechanism 6 is rotatably connected to a running wheel 9. In this embodiment, the rotation axis of the running wheel 9 coincides with the center line of the mounting frame 1. The running wheel 9 is used to contact the wall or the ground to support and stabilize the mounting frame 1.

[0039] Each mounting frame module 11 of the mounting frame 1 is provided with a handle 8. The handle 8 is located on one side of the mounting frame module 11.

[0040] The translational distance measurement mechanism 6 comprises a guide rail 65 and a slider 63 that slidably engage with each other. Both the slider 63 and the rotating support 5 are mounted on the movable base 61. A second laser distance sensor 7 is mounted at one end of the guide rail 65 and is electrically connected to the controller. A target is positioned on the movable base 61, with the laser emission end of the second laser distance sensor 7 directed toward the target. As the movable base 61 moves relative to the guide rail 65, the second laser distance sensor 7 acquires the position data of the movable base 61 in the X-axis direction. Movement of the movable base 61 can be achieved manually.

[0041] The translational distance measurement mechanism 6 also includes a horizontally arranged support plate 64, to which the second laser distance sensor 7 is connected. A guide rail 65 is mounted on the upper surface of the support plate 64. A movable base 61 is rotatably connected to at least one pair of rollers 62, which press against the support plate 64. Multiple support legs 66 are connected to the bottom of the support plate 64. Each support leg 66 is individually adjustable in height to ensure that the guide rail 65 is horizontally arranged.

[0042] When in use, first place the translation distance measuring mechanism 6 on the ground, adjust the horizontality of the guide rail 65, and then adjust the angle of the mounting frame 1 relative to the horizontal plane by rotating the support 5 according to the indicators to be measured, so that the distance measuring point of each first laser distance sensor 2 on the distance measuring scanning array can fall on the building plane to be measured (wall or ground). When it is necessary to measure the wall, set the guide rail 65 parallel to the bottom of the wall and let the running wheel 9 lean against the wall. Figure 4 When the ground needs to be measured, the walking wheel 9 is pressed on the ground, as shown in FIG. Figure 5 As shown. Each laser distance sensor is activated, and then the mobile base 61 drives the mounting frame 1 to move horizontally. During this process, each first laser distance sensor 2 continuously measures the distance between itself and the wall / ground and uses this as the first distance data. The second laser distance sensor 7 continuously measures the movement distance of the mobile base 61 and uses this as the second distance data. The gyroscope 3 obtains the angle data of the distance measurement scanning array relative to the horizontal plane in real time. The controller collects data from each laser distance sensor and gyroscope and uploads the data to the software for processing and calculation.

[0043] The controller can be connected to a smart terminal such as a computer or mobile phone via a data cable, or it can be connected to the smart terminal through wireless network communication. After the smart terminal receives the data, it can process it through software.

[0044] The measurement process only requires one person to operate, which can reduce the number of measurement personnel and has low requirements on the professional measurement level of personnel, which is conducive to reducing labor costs; the structure is simple and the production cost is low, which can be controlled below 10,000 yuan; the measurement accuracy is high and the probability of measurement error is low; it can realize simultaneous measurement of multiple indicators, which is conducive to the subsequent simultaneous calculation of corresponding data through software, and the measurement efficiency is high.

[0045] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
