SU475341A1 - Device for recording distortions of gantry crane supports - Google Patents

Description

supports 2 n 3. The crane moves along the crane rails 4. The chassis part of each of the supports 2, 3 is formed by the beam 5 and the driving wheels 6. From the end of the beam 5, the TeiiH 7 is fixed, bearing a spring-loaded rod 8 of the fork 9, in which the axis 10 of a freely rotating shaft is fixed wheels 11, fitted with a rubber rim 12. On the wheel hub 11, the cam 13 of the cardione professional profile.

The yoke 14 is attached to the plug 9, the cable, and the glands of the console 15, equipped with teiso-metric and other sensors 16, the signal of which is recorded on the oscilloscope's moving wave. When the crane is driven, the wheels 11 rotate, interacting with the rails 4.

The working signals produced by the strain gauges of the sensors 16, due to the use of elastic consoles 15 with a cam 13 of the cardinal joint, are registered in the form of uninterrupted gear lines 17, 18 (see Fig. 6).

cam (see

Profile of the left half of the fng. 5) is changed according to the law, having presented, e11, but I have the following expression:

R {(f) ...- f-Cpii,

where / (cf) is the radius vector of the perturbed point p) 0 (|) l, h cam;

/b.ip. - the minimum value of the radius-vector designated constructively; (p- arbitrary angle, replaceable from

0 ° to 180 °, expressed in radians; / - is a constant numerical coefficient depending on the design features of the device and the need for its first sensory connection.

The right butter cam profile is a mirror image of the left.

Thus, f (f) changes linearly with the change of Ko.ieca 11 for the first half of the turn from its minimum value R.n: n- to the maximum., And for the second half of the turn from the maximum of its zyachennya, l. to the minimum

Therefore, with a uniform warping, enny wheel, a strain gauge, a pitch sensor producing a symmetrical gear signal, condition ii3 of the region of the inclined nr more linear segments, corresponding to 1x; 11x for the semicircle of the wheel 11. The path traversed by the crane support along the recorded axis chart is left. 6), is defined as the sum of the projections on the vertical axis of all broken sections. Nairnmer, lolny iut I, traversed from dvpzhepp start to stop, represented by a broken line 18, is determined by the following 1 image;

Comparing the found inside / out 17 and 18, you can judge about the mutual race onor,

P.E.) e1) language1) recording allows it to be done: the hierarchs in the string of momentum are variable and with any accuracy required. According to the data on the deviations of the record in the sections
