Building wall verticality detection device

Abstract

The invention discloses a building wall verticality detection device. The device comprises a horizontal base, driving rollers, a vertical plate, height sensors and a displacement sensor, wherein the vertical plate is fixedly arranged on the horizontal base, and the displacement sensor is slidably connected to a vertical sliding rail. Each driving roller comprises an outer wheel ring, an outer eccentric wheel, an inner eccentric wheel, a connecting plate and a universal transmission mechanism, wherein the outer eccentric wheel and the inner eccentric wheel can rotate independently, and the inner eccentric wheel and the connecting plate are connected through the universal transmission mechanism; the universal transmission mechanism comprises a fixed block, a universal transmission joint and a driving shaft; each driving shaft is provided with one height sensor, and each height sensor can be used for detecting the distance between a corresponding driving shaft and the ground. The bottom of the horizontal base is connected with the driving shafts of the driving rollers through cantilevers. The device is not attached to the surface of a wall, no requirement is needed for detection time, the device can be used for detection immediately after slurry or an ash layer is leveled, testing is rapid, the detection applicability is high, and the measurement precision is high.

Description

technical field [0001] The invention relates to a detection device used in the construction field, in particular to a detection device for verticality of a building wall. Background technique [0002] In the process of decoration, it is necessary to attach a decorative surface to the wall, before which the wall needs to be smoothed and plastered; in order to ensure the verticality in the process of smoothing and plastering, a verticality detection device is required. [0003] In the existing wall decoration process, when the verticality is tested, the plumb method is mostly used, but there is no place to hang the plumb line indoors during the decoration process, and it is troublesome to use. [0004] The Chinese utility model patent application with the application number 201220053670.6, its invention and creation name is "A Wall Surface Flatness Detector Made Using the Principle of Laser Distance Measuring", which includes the laser rangefinder ruler and the light-transmitt...

Problems solved by technology

[0007] 2. When manually sticking the ruler against the wall, when the wall is not vertical, that is, when the upper and lower ends of the ruler are not on the same vertical plane, although the flatness data can be tested, the flatness data cannot be used as a reference

[0008] 3. The above-mentioned flatness detection device cannot be used on the wall just after the mud or ash layer is applied, because when the ruler is attached to the wall, it will stick to the mud or ash layer, causing the wall surface to be uneven. And the ruler can no longer be used

[0011] 1. In order to avoid the impact of the roller on the verticality of the test, a board is hinged on both sides of the roller, and the detection device is fixed through the board. However, when the detection ground is uneven or there are pits, the entire detection device will be at Slightly inclined state, so the test results are not accurate

[0012] 2. During the test, the vertical board needs to be attached to the surface to be tested. Therefore, the above-mentioned verticality detection device cannot be used for the wall just after the mud or gray layer is applied, because when the vertical board is attached to the wall , will adhere to the mud or ash layer, causing the wall surface to be uneven, and the riser can no longer be used

That is, the limit of device use time is reduced, and the detection is slow
