The lift rail perpendicularity detector

Technical field

The utility model relates to a kind of detecting instrument, and specifically it relates to a kind of special testing instrument that detects lift rail perpendicularity.

Background technology

The installation quality of the cage guide particularly error of perpendicularity of guide rail is the key factor that influences the elevator running quality, and it is the important step that guarantees the elevator installation quality that the verticality of cage guide is detected check.Requirement to lift rail perpendicularity among the GBJ310-88 " standard for quality inspection and assessment of erection works of elevators " is every 5m permissible variation 0.7mm, and the method for inspection is " messenger wire, dipstick metering inspection "." elevator supervision and inspection rules " regulation of State Administration for Quality Supervision and Inspection and Quarantine's promulgation on January 9th, 2002, the relative maximum deviation between the every 5m pedal line of every row working face of guide rail measured value all should be not more than following numerical value: car guide rail is 1.2mm with the T type counterweight guide rail that is provided with safety tongs; The T type counterweight guide rail of not establishing safety tongs is 2mm.The method of inspection is: use laser plummet or the long magnetic force plumb bob of 5m to measure along guide rail side and end face, along vertical line segmentation continuous detecting, every face is no less than 3 sections to every 5m.The method of this " messenger wire, dipstick metering inspection " slide rail verticality has been continued to use many decades at elevator industry, and its advantage is that survey instrument, measurer are simple, and measurement data is directly perceived; Shortcoming is that measuring accuracy varies with each individual, and is difficult for the realization measurement data and gathers inefficiency automatically.In recent years, release guide rail in the elevator industry and detected the use laser plummet, the JZC-A laser self leveling plumb aligner that draws special laser technology development corporation, Ltd. to produce as the development area, Dalian, substituted backguy with laser beam, accuracy of detection is increased, measuring principle and technology and " messenger wire method " are basic identical, need be by manually measuring one by one on each detection position, and measurement data is by manually reading.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of usefulness microcomputer-controlled, can be to the detecting instrument of the detection automatic data collection in the lift rail perpendicularity testing process, record, output.

The utility model is achieved by following technical proposals:

1. 2 the detection head A and detection head B that can lean against easily on cage guide side workplace or the top workplace are being set, detection head A and detection head B spacing 300～2000mm on the framework of this instrument;

2. on the framework of this instrument obliquity sensor is set, its output valve is detection head A, detection head B detection head A and detection head B point-to-point transmission line and horizontal line angle when leaning against on the tested cage guide workplace;

3. on the framework of instrument, displacement transducer is set, its output valve indication distance that this instrument moves along tested guide rail in testing process;

4. the microcomputer computer system is set on the framework of instrument, and the output of obliquity sensor, displacement transducer is linked into the input end of microcomputer, detects in the operation by microcomputer detecting automatic data collection, analysis, calculating, arrangement, output.

The utility model beneficial effect compared with prior art is: the collection that detects data does not need manually to measure one by one, read, but is directly inputted to microcomputer system by sensor, is finished by microcomputer.The time of detecting operation shortens, and the precision that detects data improves.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Detection head A1 and detection head B8 are the roller type structure among Fig. 1, are arranged on the two ends up and down of apparatus frame device, spacing 537mm.When detecting operation, detection head A1 and detection head B8 are close on the tested guide rail side workplace, contact roller 10 leans against on the tested guide rail opposite side workplace, and apply 2～3kg pressure by holddown spring 13 by pressure arm 11, to guarantee that detection head A1 and detection head B8 abut against on the tested guide rail side workplace all the time in testing process.

Obliquity sensor 5 functions that are fixed on the framework are that line and horizontal angle between detection head A1, detection head B8 and tested guide rail two contact points are carried out continuous coverage.Being equivalent to the error of perpendicularity with 0.1 ° of the every error of calibration value in this example is 1mm.Obliquity sensor is selected the WQ36-5 type for use, and resolution is 0.001 °, and corresponding verticality resolution is 0.01mm.

The displacement transducer of present embodiment and detection head A1 are combined as a whole, and the roller shaft of detection head A1 joins by spring coupling 2 and displacement transducer 4.Displacement transducer 4 is a kind of commentaries on classics scramblers of executing, and can and turn to the form of electricity consumption pulse code to export the rotation value of detection head A1 roller.

Also be provided with microcomputer system 6 and supply unit 7 in the instrument of present embodiment.The output of obliquity sensor 5, displacement transducer 4 is linked into the input of microcomputer 7.Supply unit 7 provides the electricity consumption of this instrument.
