Device for measuring wall or ground flatness by lasers

Abstract

The invention discloses a device for measuring the wall or ground flatness by lasers. The device comprises a base and a laser transmitter, the lower portion of the base is supported on a standard supporting face, the standard supporting face is the plane which is locally leveled and ground, and has the qualified flatness, the laser transmitting point of the laser transmitter is arranged in the plane of the standard supporting face, a stepped shaft is arranged in the middle of the upper portion of the base, a thrust ball bearing is arranged at the position of a small shaft of the stepped shaft, a boss is arranged on the upper portion of the laser transmitter, a stepped hole is formed in the boss, the position of a large hole of the stepped hole is matched with the thrust ball bearing, and the laser transmitter rotates around the axis of the stepped shaft through the thrust ball bearing. The device is simple and compact in laser, a constructor can conveniently conduct wall or ground flatness measurement in the construction process, meanwhile, an inspector can conveniently check and measure the flatness in the inspection and acceptance process, the measured face can be rapidly and accurately measured, and the measuring and repairing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a device for measuring the flatness of a wall surface or a ground by using a laser. Background technique [0002] In the prior art, when measuring the flatness of a building, especially for a space to be measured with a relatively small area, it is usually carried out by visual inspection or simple mobile wheel-type measuring tools, such as a ruler, a feeler gauge, etc. The defect of this measurement method is that the operator has high labor intensity, low work efficiency, poor measurement accuracy, and cannot repair the unqualified measured surface in time, especially when the flatness requirement is relatively high, this method cannot satisfy the measured surface. The requirements for surface flatness control, for complex flatness measuring equipment, the cost is high, which limits the occasions of use and affects the improvement of construction quality. There is no ...

[0002] In the prior art, when measuring the flatness of a building, especially for a space to be measured with a relatively small area, it is usually carried out by visual inspection or simple mobile wheel-type measuring tools, such as a ruler, a feeler gauge, etc. The defect of this measurement method is that the operator has high labor intensity, low work efficiency, poor measurement accuracy, and cannot repair the unqualified measured surface in time, especially when the flatness requirement is relatively high, this method cannot satisfy the measured surface. The requirements for surface flatness control. For complex flatness measuring equipment, the cost is high, which limits the occasions of use and affects the improvement of construction quality. There is no related product with compact structure and high detection efficiency in the existing technology.
