Description

A kind of device that detects crane girder side sway degree
Technical field
The utility model belongs to the device that detects crane girder, is specifically related to a kind of device that detects crane girder side sway degree.
Background technology
In bridge, trestle crane, because the crane span structure metal construction is assembled factors such as improper, girder usually inwardly or outwards deforms in the horizontal direction, and this distortion is generally weighed with the side sway degree.The side sway degree is one of most important project of detecting of crane safety, and the side sway degree that exceeds standard causes the common cause of wheel gnawing rail often.
In the prior art, for the detection of crane girder side sway degree, or adopt the method that steel wire hangs and steel ruler is measured, or adopt devices such as spirit-leveling instrument, collimator, transit and laser collimator to measure with the method for manual read's number.The former is subjected to pneumaticly to influence very greatly, and the latter then often is subjected to the restriction that put in the place, and therefore, the enforcement of these two kinds of methods all has bigger limitation, and adopts its error of method of artificial reading generally all bigger, finally causes the precision of measurement result to reduce.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and purpose provides and a kind ofly be easy to install, the device of easy to operate, precision higher detection crane girder side sway degree.
For achieving the above object, the technical solution adopted in the utility model is: this device comprises that this device comprises laser, target, microprocessor system, laser is fixed on the web of tested girder one end of crane by magnet base, target is placed on the measuring point of the tested girder web of crane, be provided with linear array transducer in the target, the output terminal of linear array transducer links to each other with the input end of microprocessor system.
Wherein: described microprocessor system comprises data collecting card, single-chip microcomputer, display screen, and data collecting card links to each other by single-chip microcomputer with display screen.
Owing to adopt technique scheme, the laser that the utility model is installed on the tested girder of crane is by magnet base absorption and be fixed on the web of the tested girder of crane easy installing/dismounting; Being used for the target of receiving beam has used linear array transducer, the irregular hot spot signal that light beam is formed changes into the luminous point electric signal, on the display screen through being presented at microprocessor system after the data acquisition process, measuring accuracy and automaticity have been improved.Therefore, the utlity model has be easy to install, easy to operate, accuracy of detection is than characteristics such as height, applicable to the detection of various bridge-types, main beam of gantry crane side sway degree.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of target among Fig. 1 (3) and microprocessor system (4).
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of device that detects crane girder side sway degree as shown in Figure 1, this device comprises laser 2, target 3 and microprocessor system 4.Laser 2 is fixed on the web of tested girder 1 one ends of crane by magnet base 5, laser 2 is sent horizontal light beam directive target 3, target 3 is placed on the measuring point of tested girder 1 web of crane, be provided with linear array transducer in the target 3, the output terminal of linear array transducer links to each other with the input end of microprocessor system 4.
In the present embodiment, the structure of target 3 and microprocessor system 4 as shown in Figure 2, wherein: microprocessor system 4 comprises data collecting card 6, single-chip microcomputer 7, display screen 8, data collecting card 6 links to each other by single-chip microcomputer 7 with display screen 8.Target 3 is bound up with microprocessor system 4, the linear array transducer that is provided with in the target 3 converts the light signal that receives to electric signal, carry out data acquisition and processing (DAP) through data collecting card 6, single-chip microcomputer 7, and with data presentation on the display screen 8 of microprocessor system 4, measure the coordinate of girder two ends and span centre position respectively.Carry out the calculating of alternate position spike then, just can obtain girder side sway degree.
This device have be easy to install, easy to operate, accuracy of detection is than high, applicable to various bridge-types, The detection of main beam of gantry crane side sway degree.
