Description

The laser deflection indicator
Technical field:
The utility model relates to deflection indicator, particularly the laser deflection indicator.
Background technology:
Measuring beam arm amount of deflection, the camber of main equipment at present measures, as the electric single-beam of crane and girder etc., mainly be to utilize special-purpose arch measurer to measure (drawing the steel wire mensuration), adopt measuring of wire rope and tape measure or spirit-leveling instrument and tape measure, manually align during measurement, the human eye interpretation, and because the downwarp that the deadweight of steel wire causes, this method must be considered modified value, cumbersome, and it is many to measure intermediate link, and it is bigger influenced by human factor, not only need to climb but also make data have certain subjectivity, precision is lower.
The utility model content:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of laser deflection indicator is provided, and is simple in structure, Intelligent Measurement, and intensity is low, and is easy to operate, the precision height.
The technical scheme that the utility model is adopted for achieving the above object is: the laser deflection indicator, by casing 11, base 1 and power supply 3 are formed, it is characterized in that: laser ranging 7 is arranged in the casing, data processor 5, adjust rotating disk 4, vertical angle adjusting knob 10 is arranged on the casing, LCD 9, keyboard 8, the laser ranging head, data processor, link to each other by data line between LCD and the keyboard, the vertical angle adjusting knob is connected to be adjusted on the rotating disk 4, data processor, the laser ranging head is fixedly connected in the core base 6, core base is arranged on to be adjusted on the rotating disk, and core base and adjustment rotating disk are for fixedlying connected;
Described laser deflection indicator, data processor has angular transducer;
Described laser deflection indicator is connected with rotary seat 2 on the base 1.
The utility model has the advantages that: equipment is simple to operation, and efficient height, design science, intelligent high are easily popularized.Being applicable to that all carry out the occasion that amount of deflection, camber are measured, is the pick-up unit commonly used of the Measuring and testing mechanism of hoisting machinery factory, maintenance department and quality supervision department mandate.
Description of drawings:
Fig. 1 is the utility model system architecture synoptic diagram.
Embodiment:
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: as shown in Figure 1: by casing 11, base 1 and power supply 3 are formed, be connected with rotary seat 2 on the base 1, laser ranging 7 is arranged in the casing, data processor 5, adjust rotating disk 4, vertical angle adjusting knob 10 is arranged on the casing, LCD 9, keyboard 8, data processor, the laser ranging head, link to each other by data line between LCD and the keyboard, the vertical angle adjusting knob is connected to be adjusted on the rotating disk 4, data processor, the laser ranging head is fixedly connected in the core base 6, and core base is fixedly connected on to be adjusted on the rotating disk; Data processor has angular transducer.Wherein adjust rotating disk and contain angle adjusting mechanism (rotating 0-90 °), angular transducer, laser ranging head (claiming stadimeter again) etc., be mainly used in the range observation of different angles around stationary shaft.The vertical angle adjusting knob can be regulated the vertical angle of rotating disk.Base is made up of horizontal rotation mechanism and triangle base, can make instrument carry out 360 degree rotations in the horizontal direction.LCD can show various states and measurement data.Carry out function selecting and correlation parameter input with keyboard.Measurement data can be preserved automatically, and can check, delete, and can be with the data importing computing machine.The utility model is used to detect the amount of deflection of crane under rated load.Measure the distance between the measurement point and measuring head and the angle of vertical direction on the tested girder under two kinds of situations of load and unloaded lotus respectively having, wherein unloaded lotus is apart from representing with the L sky, having the load distance to carry with L represents, angle represents with α, and then the measured point is unloaded lotus with the difference of vertical direction under the load condition is arranged is that the expression formula of amount of deflection is:
H=(L Empty-L Carry) sin α.
Data after the measurement can calculate amount of deflection by above-mentioned formula.
