Description
Technical field
This invention relates to a kind of caliberating device that is used for the load lifting limiter force cell, belongs to the load lifting limiter technical field.
Background technology
Load lifting limiter is mainly to be made up of pressure transducer, weighing instrument, power control box etc., is used for hoisting device, prevents a kind of safety guard that hoisting device moves under overload condition.During use wire rope directly is embedded in side-compression sensor two side channels, steel wire rope tension is converted into the pressure that the side-compression sensor bears the lifting thing is measured.In load lifting limiter is produced, owing to receive the influence that causes assembling, make the side-compression sensor that zero drift can take place, and influence the precision of sensor, therefore need go forward side by side rower calmly to the side-compression sensor measurement of each load lifting limiter.Carrying out timing signal, normally adopt counterweight to demarcate, because the profile of this kind side-compression sensor is cylindrical for the side-compression sensor that is the pivot pin shape; Because the pivot pin shape sensor promptly will the circumferencial direction of sensor be positioned, and sensor must keep motionless in loading procedure when loading the counterweight of regulation; Just can make the demonstration output valve of instrument corresponding with sensor with corresponding force value; But it is loaded down with trivial details that this scaling method is not only operated, and labour intensity is big, and it is longer to demarcate non-cutting time; Cause the whole calibrating time long, demarcation efficient is low.
Summary of the invention
It is convenient to the purpose of this invention is to provide a kind of loading and unloading calibration sensor, and can improve the caliberating device that is used for the load lifting limiter force cell of demarcating efficient.
The present invention is that the technical scheme that achieves the above object is: a kind of caliberating device that is used for the load lifting limiter force cell; Comprise support, reference sensor, Displaying Meter and calibration sensor and computing machine; It is characterized in that: the framed structure that said support is made up of entablature, sill and two columns; Displaying Meter is installed on the column of support, on the entablature of support top board is installed, and the base of lifting jack is installed on the top board; And the push rod of lifting jack is connected with the upper end of reference sensor through web member, and the lower end of reference sensor is equipped with the pressure head corresponding with gland; The sill of said support is equipped with down seat board; Following seat board is provided with pilot hole; The pilot hole that is provided with on projection and the following seat board of its bottom of supporting station of U-lag matches; Two cell walls of supporting station U-lag are provided with support holes, and its both sides of calibration sensor that are with gland are bearing in respectively in the support holes of supporting station two cell walls, and the baffle wedge that is installed on the supporting station is connected in the draw-in groove of calibration sensor; And the output terminal of calibration sensor and the output terminal of reference sensor insert Displaying Meter, the output terminal of the input termination computing machine of calibration sensor through signal wire respectively.
The present invention adopts support, on the entablature of support lifting jack is installed, and lifting jack is connected with reference sensor; The supporting base of supporting calibration sensor is installed on the cross member of support; When lifting jack is pressing down in the process, load to calibration sensor through the pedestal sensor, because calibration sensor is bearing in the support holes of supporting station; Therefore press down in the process at lifting jack; The pressure head of loading force through the reference sensor bottom remakes and is used for gland, reloads masterpiece through gland and is used for calibration sensor, guarantees that reference sensor and calibration sensor bear same loading force; Because the data of the data of the output of calibration sensor and the output of calibration sensor input to same Displaying Meter; Can directly compare through Displaying Meter, need to confirm calibration sensor whether zero drift to occur to demarcate, at timing signal; Write the nominal data of unloaded range and the nominal data of full scale according to communication mode that provides in advance and communication protocol to calibration sensor through computing machine, thus demarcate to pass the device sense demarcate very convenient.The present invention is sleeved on gland on the calibration sensor, and calibration sensor is bearing on the cell wall of supporting base, can not cause damage to required calibration sensor on the one hand; Through the clamp that is installed on the supporting base calibration sensor is circumferentially located on the other hand; Prevent the calibration sensor rotation, so the installing/dismounting calibration sensor is very convenient, shortens the nominal time; Reduce labour intensity, increased substantially the demarcation efficient of pivot pin shape sensor.
