Abstract

The utility model relates to laser level projection line compound apparatus, belonging to the field of laser measurement apparatus technology, characterized in that, a rotation axis and a scan point laser with a reflecting prism driven by a motor are arranged on the basis of the laser projection line gauge, thereby realizing high accuracy vertical lines of the projection line gauge, but also obtaining horizontal lines in large range, one apparatus double use. After the apparatus is powered on, practical position of a pendujum mass is detected by a horizon sensor on the pendujum mass, if there is an error with the horizontal plane, the horizon sensor generates signals, a trimming motor is driven by a driving circuit, to drive a trimming mechanism to move, thereby correcting the position of the pendujum mass, after the pendujum mass reaches the correct position, a vertical laser generates vertical beams, realizing vertical projection lines, a rotation motor is also working now, to drive the rotation axis for high speed rotation. A reflecting prism group with 45 degrees is mounted on the rotation axis, the beams generated by the lase point source vertically are reflected along the horizontal direction, a horizontal beam is obtained through 360 degrees of high speed rotation.

Description

Laser is put down and is thrown the line recombination optics

Technical field

The utility model relates to a kind of laser and puts down throwing line recombination optics, is the laser device that can provide level and vertical reference line fast, belongs to the laser surveying instrument technical field.

Background technology

Use in the field of straight line laser at present, the use laser level, it utilizes laser line light source, project the high-precision laser straight line of one or a few high brightness, being used for replacing traditional hanging hangs down and the line of ink marker, because the problem of manufacturing process, level mean level direction can only be accomplished 120 degree emission angle, want to realize that 360 degree horizontal lines must be with four laser modules, the cost height is debugged very difficultly, and the line source projection distance is little, generally have only 15 meters, tie detector also has only about 35 meters.And Geoplane has absolute predominance in the horizontal direction, it is with a high level of accuracy luminous point, around a Z-axis high speed rotating, thereby obtain a high level of accuracy face, because luminous energy concentrates on the point, so it uses radius can reach 300 meters, but same owing to the problem of making, scanner has just been realized not too easily to perpendicular line.

Summary of the invention

The purpose of this utility model be at existing laser level when projecting the high-precision laser straight line of one or a few high brightness, its horizontal direction but can only be accomplished 120 degree emission angle, though and Geoplane can provide 360 degree horizontal lines, but desirable not to the utmost again deficiency aspect perpendicular line, provide and both can project the high-precision laser straight line of one or a few high brightness, can in 360 degree scopes, project horizontal a kind of laser again and put down throwing line recombination optics

The purpose of this utility model is achieved through the following technical solutions, a kind of laser is put down and is thrown the line recombination optics, comprise support system, suspension system, the movement system, enclosure system and driving circuit is characterized in that the pendulum mass inner chamber in the movement system is fixed with the analyzing spot laser instrument, the turning axle with axially extending bore of upper end fixation reflex prism is set, the gear mechanism transmission that turning axle drives through electric rotating machine in the center pit of the cross that the analyzing spot laser instrument is above.

The axis of reflecting prism and turning axle is 45 degree angles, the axially extending bore of reflecting prism corresponding rotation axle.

Turning axle passes and is fixed on interior metal (upper of cross and the spacer between metal (upper.

Neutral gear, follower gear that gear mechanism is meshed successively by swing pinion constitute, and swing pinion is fixed on the spin motor shaft, and follower gear is fixed on the turning axle lower end.

The utility model gets up the advantages of existing level and scanner, the turning axle and the analyzing spot laser instrument that have reflecting prism through motor-driven are set on the basis of laser level, thereby can realize the high precision perpendicular line of level, can obtain horizontal line on a large scale again, a machine dual-purpose.Behind the machine connecting power, detect the physical location of pendulum mass by horizon sensor on the pendulum mass, as error being arranged with surface level, horizon sensor sends signal, drive the leveling motor by driving circuit, drive the flattening mechanism motion, correct the pendulum mass position to reach, pendulum mass sends vertical light by vertical laser after arriving the tram, realize the vertical line of throwing, at this moment electric rotating machine is also worked, and by gear mechanism driven rotary axle high speed rotating, one 45 degree reflecting prism groups is housed on turning axle, it reflects away the light along continuous straight runs vertically upward that the laser spots light source sends, and 360 degree high speed rotating obtain a horizontal light again.
