Description
Technical field:
The utility model relates to a kind of laser self leveling plumb aligner, is a kind of instrument that produces automatic sensing the earth's core laser beam, to satisfy the installation needs of cage guide, also can be used for other.
Background technology:
At present, the plumb aligner device of producing and using is a lot, what wherein have is laser self leveling plumb aligner, but all can not satisfy the requirement that cage guide is installed, mainly be because its precision is low, reason is that the autocompensation installation in the existing instrument all is to use whole gravity to hang or hangs prism with hairspring and realize, wherein all relate to axle and bearing, promptly all exist mechanical friction, and certain amount is always arranged by the error that mechanical friction produced, and its randomness is very big, therefore influenced the instrument precision of compensation automatically, make very little that the standard deviation of instrument is difficult to subtract, the data repeatability that is to say measurement is bad, and the accuracy requirement that cage guide is installed is except guaranteeing certain verticality, also requiring two guide rail spacings error in omnidistance is 0-+2mm, so existing plumb aligner can not satisfy its accuracy requirement, therefore when cage guide is installed, the methods of traditional ceiling hammer that adopt are carried out the unwrapping wire location more, two cage guide spacings are then utilized and are looked for track forces to measure piecemeal controlling, this method not only bothers, precision is low, and can not solve the problem of on-line measurement, because of must having framing scaffold, could implement said method, when checking and accepting and keep in repair, do not possess under the framing scaffold situation like this, can only lean on 5 meters long magnetic force plumb bob to carry out as benchmark, so precision is low, cumulative errors is uncontrollable, and above-mentioned conventional mounting mode can not satisfy the requirement of present elevator safety operation.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, laser self leveling plumb aligner that measuring accuracy is high, easy to use, overcomes the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of laser self leveling plumb aligner, it is characterized in that: be provided with laser instrument 1 in the eyepiece stalk 2, the bottom of eyepiece stalk 2 and objective holder 4 join, objective holder 4 joins with chassis 10, be provided with liquid wedge automatic compensator 7 in chassis 10, be provided with the space phase modulator between laser instrument 1 and the liquid wedge automatic compensator 7,10 tops, chassis are provided with shell 14, chassis 10 falls to being sitting on the pallet 12, and pallet 12 connects jig 18.
The top of described laser instrument 1 is provided with garden bubble 11.
Between described pallet 12 and the jig 18 is that three burr adjustable tail margin spirals connect.
The utility model compared with prior art has following advantage: can produce the high-precision laser bundle that points to the earth's core, simple in structure, price is low, easy to use and carry, can be widely used in installation, examination and the maintenance of upright walking cage guide, and high-precision plumb datum is provided in the installation of high-building construction, tun, pylon.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the utility model course of work synoptic diagram.
Embodiment:
As shown in Figure 1: the 2nd, be positioned at the eyepiece stalk of shell 14, at eyepiece stalk 2 internal fixation semiconductor laser 1 is arranged, the inboard bottom that the below of semiconductor laser 1 is positioned at eyepiece stalk 2 is equipped with eyepiece component 3 and is joined with the upper end of objective holder 4.The bottom of objective holder 4 and chassis 10 join, be provided with flat mirror 8 and compensation liquid 9 in the chassis 10, its structure is two closed containers that are made of three layers of flat mirror 8 and compensator housing, in these two containers can transparent compensation liquid 9, above constituting the flat mirror of container bottoms, formed two liquid lenss.The upper surface of liquid lens is that Free Surface promptly is a surface level, and it is the reference field of this device.The mechanical axis of instrument is different with the angle of theoretical vertical line and changing at ordinary times along with the instrument initialization for the angle of wedge of these two liquid lenss.They have following characteristic, and when the refraction coefficient sum of this two-layer liquid is " 3 ", no matter how many angles of the first horizontalization of instrument is, the laser beam of going out from this wedge of liquid lower surface will be the strict the earth's core of pointing to, and error is " 0 " in theory.Just can manage full remuneration in fact.This point is that any physical construction is all incomparable.Flat mirror 8 has been formed liquid wedge automatic compensator 7 with compensation liquid 9, and this liquid wedge automatic compensator 7 is a prior art, is that clearly record is arranged in 95231114.3 patent specifications in the patent No., is not described in detail in this.
The bottom inside of objective holder 4 be positioned at liquid wedge automatic compensator 7 above object lens 5 and light hurdle 6 are housed, formed the space phase modulator by eyepiece component 3, object lens 5, the light hurdle 6 of eyepiece stalk 2 bottoms.This space phase modulator is a prior art, is record to some extent in 97225486.2 patent specifications in the patent No., is not described in detail in this.Eyepiece stalk 2 relatively-stationary object lens and Guang Lan can move forward and backward, so that obtain best energy distribution on the xsect of laser beam, promptly finish the regulatory function of space bit phase modulation by regulating.Eyepiece stalk 2 can also be along radially doing a small amount of the adjustment simultaneously, the incident angle that laser beam is carried out liquid wedge is adjusted in radial displacement by eyepiece component 3 relative object lens, adjust the purpose that laser beam is left the emergence angle of liquid wedge compensator thereby reach, just reach the purpose of adjusting the vertical accurate precision of instrument.
Shell 14 covers on the chassis 10, and its inner side edge is equipped with power supply 15 and is connected with semiconductor laser 1 lead, and is provided with switch 16.
Above objective holder 4, be provided with support, be screwed garden bubble 11, make garden bubble 11 be positioned at the top of semiconductor laser 1, leave viewport on the top of shell 14, so that observe garden bubble 11.
Laser self leveling plumb aligner disclosed in the utility model is highly suitable for the installation and the detection of cage guide, allowing alignment error for hundred meters high guide rail rail spacings is 0-2mm, laser self leveling plumb aligner described in the utility model solves by following method: because the structure of two guide rails in the space is axisymmetric, as shown in Figure 2: 19 is tested cage guide, 22 is laser beam, by jig 18 this device is fixed on the guide rail 19.It also is axisymmetric that twice on two guide rails of this sampling instrument is installed, the laser beam of twice ejaculation this moment is inevitable also to be axisymmetric (rather than parallel), want to reach the requirement of 0-2mm, the verticality precision of laser beam will reach 0-1mm at least, just the vertical accurate precision of instrument remain at ± 1 " scope in, and this is very difficult.The utility model is not means of taking to improve merely the vertical accurate precision of instrument, but after being installed on second guide rail with tool housing together with movement Rotate 180 °, adjusting the footing spiral simultaneously makes the bubble in the bubble of garden placed in the middle, after handling like this, the laser beam that penetrates after second guide rail is installed will realize parallel with the laser beam that the back that is installed at first guide rail is penetrated in the space, its precision can satisfy the requirement that guide rail is installed fully, and this is that to have utilized the existing error of the utility model mainly be this advantage of systematic error clocklike.
Two wedges 13 are installed on the lock sleeve 20 of 10 bottoms, chassis, and its effect is to produce the usefulness of revising after the micro-deformation face drifts about laser beam when the release owing to stress in the part.
