This trolley micro-adjusting mechanism realizes the process of fine tuning: right when the floating junction in left side reduces down under hydraulic action
The floating junction of side is up promoted under hydraulic action, and the rear side of hitching frame is located at spherical shape around ball cover axial direction left side
The spherical upper cover and spherical lower cover for covering upper and lower connection will be tilted around ball cover axis under force, the front side of hitching frame
Affixed with floating junction, so that the front side of hitching frame is also with inclination, then micro-adjusting mechanism integrally also just tilts to the left, is formed
Micro-adjusting mechanism may be implemented under actual tests demand and adjust in 0~10 ° of range leaning angle for left low and right high situation.
Similarly, when the floating junction on right side reduces down under hydraulic action, the floating junction in left side is under hydraulic action
It is up promoted, the rear side of hitching frame is located at round spherical shape and puts in the spherical shape that lower section connects around the axial right side inclination of ball cover
Lid will be tilted around ball cover axis under force with spherical lower cover, with floating junction the front side of affixed hitching frame also with
Inclination, then micro-adjusting mechanism integrally also just tilts to the right, forms right low left high situation, may be implemented under actual tests demand
Micro-adjusting mechanism is adjusted in 0~10 ° of range leaning angle.And since the hanging plate of hanging mechanisms and hitching frame is affixed, test equipment is logical
It crosses on hanging mechanisms mounting and hitching frame, to test the incident angle pendulum of equipment range within 10 ° when driving actual job
It is dynamic, optimum position and data information are obtained with this, it is exactly so-called roll fine tuning that tilt angles adjustment in left and right, which is combined,.
When the floating junction in left side reduces down under hydraulic action, the floating junction on right side is under hydraulic action toward decline
Low, hitching frame is tilted around ball cover axial front side, while will positioned at the spherical spherical upper cover for covering upper and lower connection and spherical shape lower cover
It is tilted under force around ball cover axis, since hitching frame is affixed with floating junction, hitching frame while also just forwards
Inclination, forms low early and high after situation, micro-adjusting mechanism may be implemented under actual tests demand in 0~10 ° of range leaning angle tune
Section.
When the floating junction on right side is up promoted under hydraulic action, the floating junction in left side up mentions under hydraulic action
It rises, hitching frame is tilted around ball cover axial front side, while will positioned at the spherical spherical upper cover for covering upper and lower connection and spherical shape lower cover
It is tilted under force around ball cover axis, since hitching frame is affixed with floating junction, hitching frame while also just rearward
Inclination, then micro-adjusting mechanism integrally also just tilts downwards, and the hanging plate of hitching frame and hanging mechanisms are affixed, this just drives examination
Testing equipment, according to test demand, the tilt adjustment of range and position are swung within 10 ° in actual job, and the front is high and the back is low for formation
Situation, optimum position and data information are obtained with this, it is exactly so-called pitching fine tuning that upper and lower tilt angles adjustment, which is combined,.
