Description of drawings
Below in conjunction with the drawings and specific embodiments to the utility model be elaborated-
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side sectional view of Fig. 2.
Embodiment
As depicted in figs. 1 and 2, the shop experiment pick-up unit of portal crane wind resistance servo stabiliser of the present utility model comprises basic platform 101, test bed framework 102,3 vertical loading oil cylinders 6, weight transfer casing 7, bogie frame 8, set of wheels 81, rail 21 and horizontal thrust oil cylinders 2.
Wherein, rail 21 is tiled on the basic platform 101; Test bed framework 102 is made of crossbeam 5, four root posts 3, and wherein four root posts, 3 apportion both sides and lower end are by hinge is installed on the basic platform 101, the upper end supports crossbeam 5 by stud connection two ends.
3 vertical loading oil cylinders 6 are fixed on crossbeam 5 belows, and its lower end connects weight transfer casing 7, then are connected by hinge and bogie frame 8 tops are middle in the middle of weight transfer casing 7 lower ends.81 bottoms that are installed in bogie frame 8 of set of wheels.Set of wheels 81 is positioned on the rail 21, and the both ends, the left and right sides of set of wheels 81 tops are equipped with respectively wind-proof iron wedge detent interface and rim brake interface, are respectively applied to install wind-proof iron wedge detent and rim brake.Horizontal thrust oil cylinder 2 is positioned at test bed framework one side, and the one end is installed on the cylinder bracket 1 on the basic platform 101, and the other end then is connected to bogie frame 8 central bottom by the forked horizontal push 22 of tool.The gravity of vertical loading oil cylinder 6 simulation cranes is applied on vehicle wheel frame 8 and the set of wheels 81 by bearing pin, makes the wheel load of two wheels impartial.
Be offset rollover for guaranteeing that the bogie frame motion is not instead given birth to, on basic platform 101, also be fixed with the side supports 103 that is positioned at bogie frame 8 both sides, be provided with the side roll 104 with bogie frame 8 contacts side surfaces in this side supports 103.
Because the thrust of horizontal thrust oil cylinder is very large during test, for guaranteeing bogie frame 8 motions steadily, be not offset, be fixed with the guide rail 23 that is positioned at horizontal push 22 both sides at basic platform 101, and horizontal push 22 both sides be provided with the side roll 24 that is positioned at guide rail 23.
Horizontal thrust oil cylinder 2 cooperates horizontal push 22 and guide rail 23 so that the compressing cylinder motion is balanced, and can bear horizontal counter-force.When the horizontal force of simulation wind reaches when vehicle wheel frame is moved, can make connection bracket and load the displacement that produces small distance between crossbearer.In set of wheels 81 lower side the displacement transducer of monitoring wheel sliding motion is housed.
The Hydraulic Station of hydraulic system is by a motor-driven oil pump feed, the hydraulic control components such as solenoid directional control valve, pressure transducer, surplus valve are set above hydraulic reservoir, fluid pressure line between Hydraulic Station and the test-bed adopts hard tube to connect, and then adopts flexible pipe to be connected to each hydraulic jack.
By the spring brake application, hydraulic pressure declutches the hydraulic oil pump of two clip wheel devices in process of the test.The action of mentioning of wind-proof iron wedge is carried out by electric hydaulic pusher (hydraulic push rod).
