Abstract
The invention discloses a braking glide quality tester for a crane. The tester comprises a reflective tape adhered on the lateral side of a travelling pulley group of the crane, a focused laser sensor sensing a reflective tape signal and a controller, wherein the focused laser sensor is arranged on a lift device, and is provided with a displace sensor; and the controller is provided with a braking control module which starts a braking device of the crane according to the fact that whether a photoinduction signal of the focused laser sensor exists or not, a lift device control module which controls lifting of the lift device according to the fact that whether the braking process of the crane is completed or not, and a glide quantity calculation module which calculates the braking glide quantity according to displacement data of the displace sensor. The tester can detect the glide quantity after the crane brakes in real time, and feeds back information to an operator, so the operator can understand the working performance of the crane conveniently; and regarding special hoisting operation with position accuracy requirement, the tester is convenient for the operator to select proper braking time to brake so as to improve the working efficiency.
Description
Technical field
The present invention relates to hoisting crane, relate in particular to a kind of hoisting crane brake slide flowmeter.
Background technology
In actual production, use the brake slide tester that the brake slide amount of hoisting crane is carried out periodic measurement, can make operating personal grasp the serviceability of crane brake, accomplish to know what's what, for the special hoisting operation that position accuracy demand is arranged, grasp suitable braking and brake opportunity, can increase work efficiency, alleviate labor intensity of operating personnel.Can this judge as foundation whether the brake slide amount of hoisting crane surpasses specified value as quality testing department; If downslide amount exceeds standard range, then stop the hoisting operation of this hoisting crane, and overhaul.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of hoisting crane brake slide flowmeter, make the crane operation personnel can conveniently recognize the braking situation of hoisting crane.
Technical scheme: for achieving the above object, the technical solution used in the present invention is:
A kind of hoisting crane brake slide flowmeter comprises the reflecting strips that sticks to hoisting crane running block side, the focusing laser sensor and the controller of induction reflecting strips signal; Described focusing laser sensor is arranged on the jacking system, and focusing laser sensor is provided with displacement pickup; Described controller inside is provided with photoinduction signal according to focusing laser sensor and has or not the control of braking module that starts crane braking device, whether finishes the jacking system control module of controlling the jacking system lifting and the downslide amount computing module that calculates the brake slide amount according to the displacement data of displacement pickup according to the hoisting crane braking procedure; The photoinduction signal output part of described focusing laser sensor connects the input end of control of braking module, the control signal output ends of control of braking module connects crane braking device, the feedback signal mouth of control of braking module connects the input end of jacking system control module, the mouth of jacking system control module connects jacking system, and the displacement data mouth of described displacement pickup connects the data input pin of downslide amount computing module.
During work, at first start survey meter, by focusing laser sensor search reflecting strips, after focusing laser sensor searches reflecting strips, displacement pickup writes down current focusing laser sensor position, control of braking module in the controller starts crane braking device simultaneously, and hoisting crane begins braking; After the braking of hoisting crane is finished, the control of braking module feeds back signal to the jacking system control module, the lifting of control jacking system, make focusing laser sensor can search reflecting strips, after focusing sensor searches reflecting strips, jacking system quits work, and the simultaneous displacement sensor writes down current focusing laser sensor position once more; The downslide amount computing module obtains the brake slide amount after the location information of the focusing laser sensor of twice record is handled.
