The end end face that described positioning rotating shaft inserts first locating hole is provided with a circular trough, is distributed with a circle steel ball in the groove.
Compared with prior art, the beneficial effects of the utility model are: when the displacement of supporting traverse generation cross-bridges direction, linkage between supporting traverse and the crossbeam control cabinet can rotate, during rotation, under the steel ball effect, can reduce the torsion influence that the high-damping rubber post is subjected to, prolong the life-span of high-damping rubber post.Each is subjected on the contact surface of frictional force, adopts the hard chrome plating steel, has improved abrasive resistance greatly, and adopt multistage steel platform at the pressure-bearing place, if rubbing surface damages, then only change the top friction portion to get final product, when maintenance and inspection rubbing surface, pull down this multistage steel platform simultaneously, can easily carry out.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with drawings and Examples.
As shown in drawings, a kind of multi-directional deflection damp type of the utility model stretching device, comprise crossbeam control cabinet 1 and beam shaped steel 2, supporting traverse 3 is arranged in the crossbeam control cabinet 1, supporting traverse 3 tops link to each other by the case top of upper bracket and crossbeam control cabinet 1, link to each other at the bottom of the case of supporting traverse 3 belows by undersetting and crossbeam control cabinet 1.
Wherein, upper bracket comprises positioning rotating shaft 4, one end of positioning rotating shaft 4 is provided with a circular trough, be distributed with a circle steel ball in the groove, this end of positioning rotating shaft 4 inserts in first locating hole on 1 case top of described crossbeam control cabinet, when the displacement of cross-bridges direction takes place supporting traverse 3, whole upper bracket can rotate along positioning rotating shaft 4, thereby the increase displacement, and under the effect of this circle steel ball, rotate very easy.One end of another termination first steel round platform 6 of positioning rotating shaft 4, this end of the first steel round platform 6 is provided with the first hard chrome plating steel plate 5 around positioning rotating shaft 4, the other end is connected with an end of high-damping rubber post 7, another termination second hard chrome plating steel plate 8 of high-damping rubber post 7.The first hard chrome plating steel plate 5 and the second hard chrome plating steel plate 8 are in order to increase the abrasion resistance of contact surface, and when there is the vertical direction displacement difference in two crossbeam control cabinets 1, high-damping rubber post 7 deforms, make the upper surface integral body of beam shaped steel 2 that the inclination of certain angle take place, avoid occurring dislocation and jump the car phenomenon.
