As above describe the structural arrangement and the principal character thereof of the preferred embodiment of the present invention in detail,, further specify from operation principles of the present invention and force analysis briefly below in order to embody advantage of the present invention and beneficial effect more significantly.
1). the self adaptation motion analysis:
Directly explanation might as well be omitted the less important part in this brake gear for convenience, as: hydraulic actuating cylinder inner structure, spring installation etc.
As shown in figure 16, if carrying roller 8 ' exist factors such as installation error and two brake arms, 3 location deviations to cause Position of Hydraulic Cylinder and two brake arms, 3 decentraction, the present invention can descend in the process of hydraulic actuating cylinder lifting in working order, since cylinder body 1 ' can be around the swing of gudgeon centre line L, and can be around by locating dowel pin 5 ' pivot bonded assembly jaw 4 ' swing together with tapered wedges 11, so both can form the self-adapting float system.According to the situation of lateral resistance, this self-adapting float system can the automatic compensation hydraulic actuating cylinder and the deflection angle of tapered wedges 11, finally makes hydraulic actuating cylinder be in an almost location status of absolute zero unbalance loading.This moment, hydraulic actuating cylinder only bore pure axial force, thereby reached the elimination hydraulic actuating cylinder, and the purpose of further piston in hydraulic cylinder bar 2 ' unbalance loading.
2). stressed principle analysis:
As shown in figure 17, suppose that the hydraulic actuating cylinder hoisting force is F, 11 pairs of both sides brake arms of tapered wedges 3 contact inclined-plane pressure straight up F/2 that respectively does for oneself then is so because the effect of wedge is applied to the positive pressures on the two contact inclined-planes
Wherein α is the angle of bevel on inclined-plane, this brake gear angle of bevel can be designed to 25 °, as calculated, the positive pressure N that is applied on the two contact inclined-planes is about 1.2F, therefore, the effect of the less hoisting force F of hydraulic actuating cylinder by tapered wedges 11 can to each brake arm 3 all produce bigger positive pressure 1.2F and finally be applied to carrying roller 8 ' on, thereby increased braking effect.
It can also be seen that from Figure 17 both sides carrying roller 8 ' for its horizontal component opposite sign but equal magnitude of antagonistic force of two brake arms 3 can self-equalizing, hydraulic actuating cylinder only bears the component of vertical direction.In addition, because the coil of strip disturbance causes the tangential force F that carrying roller 8 ' rotation is produced
1Can be almost fully by brake arm 3 pass to trolley bracket 7 ', and finally by trolley bracket 7 ' bear.This shows that this modifying device has significantly reduced the work load of hydraulic actuating cylinder, obviously improved its stressing conditions, for reducing its fault, it is significant to prolong its service life.
