This device also comprises a pair clamping plate, and it is vertically set on base, and is positioned at the both sides of two wedge blocks.
This device also comprises some to pre-tightening apparatus, and it is connected with the end of wedge block respectively, carries out pretension by often pair of pre-tightening apparatus to two wedge blocks; Often pair of pre-tightening apparatus comprises two pretension parts.
Described pretension parts comprise:
One pretension bolt;
One spring, one of them wedge block end is withstood in its one end, and the other end is connected with pretension bolt.
Wedge block described in a pair is relative sliding under the effect of the spring force of pre-tightening apparatus respectively, and the mobile cushion block described in promotion moves; Or the mobile cushion block described in promotion moves down, make the wedge block slide in opposition described in a pair.

Fig. 3 is the stressed schematic diagram of the bearing support assembly of the highly automated adjustment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, a kind of bearing support assembly of highly automated adjustment, comprises: base 1, and base 1 offers several bolts hole 11; A pair wedge block 2, it is symmetricly set on the upper surface of base 1, and makes the normal of the lozenges of two wedge blocks 2 intersect above lozenges; Mobile cushion block 3, it is arranged on a pair wedge block 2, parallel motion a pair wedge block 2, makes mobile cushion block 3 up-and-down movement; A pair clamping plate 4, it is vertically set on base 1, and is positioned at the both sides of two wedge blocks 2.3 pairs of pre-tightening apparatus, it is connected with the end of wedge block respectively, carries out pretension by often pair of pre-tightening apparatus to two wedge blocks; Often pair of pre-tightening apparatus comprises two pretension parts, and two pretension parts push down one end of two wedge blocks respectively, is connected with corresponding clamping plate simultaneously.
As shown in Figure 2, above-mentioned pretension parts comprise: a pretension bolt 51; One spring 52, one of them wedge block 2 end is withstood in its one end, and the other end is connected with pretension bolt 51.
A pair wedge block 2 relative sliding under the effect of the spring force of pre-tightening apparatus respectively, promotes mobile cushion block 3 moves; Or, promote mobile cushion block 3 and move down, make wedge block 2 slide in opposition described in a pair.Mobile cushion block 3 bottom surface comprises two symmetrical inclined-planes, and described inclined-plane is attached on lozenges.
In a particular embodiment, bearing frame is set on mobile cushion block 3, as shown in Figure 3, suppose that bearing negative load forces is F, the predetermincd tension of spring is P1 (P2), the inclination angle of wedge block 2 is α, then, as P1=P2=F/2tan α, wedge block 2 and mobile cushion block 3 just reach a state of equilibrium and maintain static.When bearing seat sinks because of shipbody deformation, this bearing support assembly can move down thereupon bearing load F is reduced, i.e. P1=P2>F/2tan α.Now, wedge block 2 by under the effect of spring force P1 and P2 to middle slip, thus promote mobile cushion block 3 to move, until reach P1(P2) state of equilibrium of=F/2tan α.Otherwise when lifting on bearing seat is because of shipbody deformation, bearing load F can increase, and makes P1(P2) <F/2tan α.Then promote mobile cushion block 3 to move down, promote wedge shape sliding, 2 to two Slideslips, until reach P1(P2) state of equilibrium of=F/2tan α.Rotate pretension bolt 51, can the predetermincd tension of regulating spring 52, to adapt to the needs that different load bearing seat is installed, such bearing installation steps also greatly simplify
In sum, the bearing support assembly of a kind of highly automated adjustment of the present invention, bottom the middle bearing being arranged on the main Propulsion Systems of boats and ships, be used for the weight of pivot shaft system, pass through screwing bolts, the predetermincd tension of regulating spring, to adapt to the needs that different load bearing seat is installed, simplifies bearing installation steps greatly.
Although content of the present invention has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
