Accompanying drawing explanation
The above and other feature of the present utility model, character and advantage become more obvious by the description by below in conjunction with drawings and Examples, wherein:
Fig. 1 is that the axle of an embodiment's of the utility model hydraulic actuator height-adjusting device is surveyed view.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
Accompanying drawing 1 is all only as example, and it is not to draw according to the condition of equal proportion, and should not using this as the protection domain of the utility model actual requirement is construed as limiting.
Hydraulic actuator 5 can be electro-hydraulic servo actuator, hydraulic energy from hydraulic power can be converted to mechanical energy, the displacement transducer that also can carry by product as required or position limit switch carry out servocontrol, mainly by elements such as hydraulic efficiency servo-valve, hydraulic actuator, displacement transducer, pressure transducer, load transducer, vibration dampers, formed, in Fig. 1, its front end is front end, and rear end is left end, and A is shown in Figure 1 for its power outbound course.Left end at hydraulic actuator 5 provides flange plate 51, at right-hand member, provides hanger 52.
Corresponding to front end, the rear end of hydraulic actuator 5, hydraulic actuator height-adjusting device comprises front end bearing 2 and rear end bearing 1.
Front end bearing 2 is for bearing the gravity of the front end of hydraulic actuator 5, and rear end bearing 1 is for bearing the gravity of the rear end of hydraulic actuator 5.
Referring to Fig. 1, front end bearing 2 is 7 character form structures, by side cross tube 21,22 and base plate 23, be welded, in each bight, stiffening plate is set, cost can be done very lowly, square tube 21 is cantilever beam structure, runs through connecting screw rod 3 in square tube 21, and in the upper and lower side of square tube 21 respectively by nut 31,32 fastening or locking by screw rod 3.Unclamp nut 31,32, rotating screw bolt 3, just can be at the height of vertical direction free adjustment screw rod 3.
