Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and more particularly to a measuring device used in building engineering construction. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of their supporting lines, pipelines and equipment. Among them, building buildings refer to projects with roofs, beams, columns, walls, foundations and can form internal spaces to meet people's needs for production, residence, study and public activities; the measurement of construction engineering construction includes land leveling and earthwork calculation of the site, positioning measurement of buildings and structures, detailed positioning measurement and elevation measurement of buildings and structures, axis projection of high-rise buildings, and installation positioning measurement of structures and accessories; among them, the verticality of a building is the degree of deviation in the vertical direction of the building, and is an important indicator to measure the rationality of the building's form. The verticality of a building directly affects the structural stability of the building. When the verticality of a building does not meet the standard, the bearing capacity of the building will be weakened, which will bring potential safety to the structural safety of the building. At the same time, the verticality also affects the appearance of the building. Buildings with poor verticality will give people a feeling of tilt and distortion, affecting the overall appearance. Therefore, it is necessary to test the verticality.

Workers manually measure the distance from each position in the vertical direction of the wall to the plumb line. Workers are prone to measurement errors when measuring verticality, and calculation errors are also prone to occur when calculating based on the measured data, resulting in low measurement accuracy of the verticality of the building wall; secondly, the existing measuring device can improve the accuracy of the verticality measurement of the building, but during the measurement, the ground will be uneven, causing the measuring device to be unable to be in a horizontal state, which has an adverse effect on the measurement of verticality.

[0027] The working principle of the present invention is as follows: the measuring device is pushed to the wall of the building with the handrail 104. When the ground is uneven and the device is tilted, the vertical line 403 and the plumb block 404 move under the influence of gravity. At this time, the plumb block 404 is away from the ends of the first positioning plate 406 and the second positioning plate 407 or is pressed against the first positioning plate 406 and the second positioning plate 407, which is conducive to clearly showing the balance state of the measuring device and providing conditions for the leveling device 2 to perform leveling. According to the position of the plumb block 404, the leveling device 2 at the four corners of the bottom plate 101 is adjusted. 2 respectively, by turning the knob 204, the worm 203 is rotated, so that the worm wheel 206 is rotated, the rotation of the worm wheel 206 drives the rack 207 to move, and then the outer shell 208 can move up and down, which is conducive to adjusting the horizontal state of the measuring device to prevent it from affecting the vertical measurement. After the horizontal state of the measuring device is adjusted, the control button on the digital display console 105 is pressed to make the second motor 306 work, drive the second coupling 307 and the second threaded rod 308 to rotate, and the second threaded rod 308 rotates so that the second threaded rod 308 connected with the threaded rod 308 can move up and down. The lifting ring 309 can move up and down on it, and the lifting ring 309 drives the connecting piece 501 to move up and down in the slide groove 310, that is, drives the electric telescopic rod 504 on the buckle ring 502 to move up and down, and then adjusts the initial height of the measuring component 6, and then the electric telescopic rod 504 works to make the measuring component 6 move horizontally, and the measuring head of the measuring rod 604 of the measuring component 6 slowly moves to contact the wall. When the measuring head contacts the wall, the electric telescopic rod 504 stops working, and the three-coordinate sensor 601 is positioned through the function button 603. The point is the coordinate origin, and then the second motor 306 is used to move the measuring component 6 upward. The measuring head of the three-coordinate sensor 601 moves upward along the wall, and the coordinates are displayed on the digital display screen 602 while being transmitted to the digital display console 105 for calculation to obtain the verticality of the wall. When the wall is too high, the first motor 305 is enabled to work, and the first motor 305 rotates the first threaded rod 303 in the threaded sleeve 302 through the first coupling 304, thereby moving the column 301 upward to increase the height measurement range of the measuring component 6.

[0028] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
