Abstract
The utility model relates to an auxiliary device for tunnel construction marking, in particular to a laser radioactive beam monitor, which is used for solving the problems of waste of time and labor and the influence on construction efficiency existing in measurement marking and installation quality detection of the conventional tunnel cable rack. The laser radioactive beam monitor comprises a laser instrument body, wherein the laser instrument body comprises a bracket; a rotary lens barrel is hinged on the bracket; an angle gauge which is superposed with the axle center of the rotary lens barrel and is arranged below is fixed on the rotary lens barrel; and a straight ruler of which the graduations are aligned with the graduations of the angle gauge and is fixed with the bracket is arranged under the angle gauge. The auxiliary device has a reasonable and reliable structural design, three persons can complete marking within a half workday specific to a tunnel of about 5 kilometers, and the detection accuracy is over 95 percent; and meanwhile, the auxiliary device has the advantages of simple structure, lightness for carrying, convenience, rapidness and easiness for operating.
Description
Technical field
The utility model relates to the constructing tunnel line and uses servicing unit, is specially a kind of laser laying out instrument.
Background technology
In the tunnel illumination engineering, all (the flat right side of leading) wall adopts Cable hanger according to last and lower leaf is laid along positive hole tunnel left side for light distribution trunk cable circuit and light distribution branch cable circuit; Detect for the measurement line of Cable hanger and installation quality that existing wastes time and energy influences the problem of operating efficiency.
Summary of the invention
The utility model is measured line and installation quality and is detected that existing wastes time and energy influences the problem of operating efficiency in order to solve the existing tunnel Cable hanger, and a kind of laser laying out instrument is provided.
The utility model is to adopt following technical scheme to realize: the laser laying out instrument; Comprise the laser body; The laser body comprises support; Be hinged with the rotation lens barrel on the support, rotation is fixed with the protractor with its axis coinciding and underlying on the lens barrel, the ruler that is provided with under the protractor that scale aligns with its scale and fixes with support.During use; At first place the laser laying out instrument; Measure laser laying out instrument rotating shaft center apart from the distance of tunnel wall and the distance (fixed value) of laser laying out instrument base to lens barrel rotating shaft center,, calculate the anglec of rotation that needs the rotary laser lens barrel according to the setting height(from bottom) of the Cable hanger of working drawing design; After rotating to required corresponding scale to the laser lens barrel then; Adjustment laser laying out instrument projecting laser pattern, making its throwing is a red horizontal light beam on tunnel wall, two people pull out print cartridge, snap the line then; For mounted uniform Cable hanger; Whether satisfy the requirement of design height for detecting it; Set the angle of required laser lens barrel, make its red beam of getting a level, see whether mounted Cable hanger is in the position of the red light velocity; Whether the installation site that so just can accurately detect project completed meets design requirement; According to error range, before hanging cable, suitably adjust, overcome the existing tunnel Cable hanger and measured line and installation quality and detect that existing wastes time and energy influences the problem of operating efficiency.
The utility model reasonable in design is reliable; Tunnel for about one 5 kilometers; Three people just can accomplish line half working day, and accuracy of detection has advantage simple in structure, that carrying is light, convenient and swift and simple to operate simultaneously more than 95%.
