Also comprise manual self-locking position-limit mechanism, comprise handwheel, bevel gear and screw rod, handwheel one end is through bevel gear and screw rod lower ends, and the elevating mechanism lower end is provided with swivel nut, and through the locking that is nested of screw thread on swivel nut lower end and the screw rod.
Said elevating mechanism is provided with suspension bracket, and the suspension bracket both sides are respectively equipped with suspension rod, the suspension rod bottom is provided with scale pan, and said counterweight is stacked and placed on the scale pan.
Adopt the shop experiment pick-up unit of electro hydraulicthruster of the present invention, have following advantage:
1, simple in structure, easy to use, testing efficiency is high, effective;
2, practical working situation and pusher promoted control can be simulated, the demand that the shop experiment of electro hydraulicthruster detects can be satisfied fully;
3, through automatically controlled test macro, relatively elevating mechanism rises and fall time, comes automatic monitoring and the record of realization system to process of the test, effectively prevents to cause electro hydraulicthruster directly to damage because of mechanical or electric reason.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and embodiment the present invention:
Fig. 1 is the structural drawing of experiment detection device of the present invention.
Fig. 2 is the side view of experiment detection device of the present invention.
Embodiment
Like Fig. 1-shown in Figure 2; The shop experiment pick-up unit of electro hydraulicthruster of the present invention mainly comprises frame 1, elevating mechanism 2, position transducer 3 and automatically controlled test macro; Frame 1 adopts the welded type one-piece construction, is welded by steel plate, and its effect is that pilot system is supported.Frame 1 bottom is provided with pusher mount pad 4, is used to install tested electro hydraulicthruster 5, also is provided with the rail assembly 6 that supplies elevating mechanism 2 to go up and down on the frame 1.Elevating mechanism 2 is located on the rail assembly 6, and elevating mechanism 2 is provided with pusher head contiguous block 7, is used for linking to each other with the head of tested electro hydraulicthruster 5, and the action through pusher 5 can drive elevating mechanism 2 and go up and down along rail assembly 6.And also hang on the elevating mechanism 2 and be provided with counterweight 8; Be used to apply the simulation load; Specifically be provided with as follows: elevating mechanism 2 is provided with suspension bracket 9; Suspension bracket 9 both sides are respectively equipped with suspension rod 10, suspension rod 10 bottoms are provided with scale pan 11, and said counterweight 8 is stacked and placed on the scale pan 11, make things convenient for the counterweight 8 of load-bearing to change on demand.Position transducer 3 is located at frame 1 one sides, is used to detect the up-down displacement of elevating mechanism 2.The data acquisition of automatically controlled test macro collection, PLC are controlled in all over the body automatically, through the simulation practical working situation pusher 5 are promoted control, and the detection data of receiving position sensor 3 and promotion number of times, and then draw the technical feature of pusher 5.
This experiment detection device also comprises a manual self-locking position-limit mechanism; Comprise handwheel 12, bevel gear 13 and screw rod 14; Handwheel 12 1 ends are through bevel gear 13 and screw rod 14 lower ends; Elevating mechanism 2 lower ends are provided with the jacking block of band swivel nut 15, and through the locking that is nested of swivel nut 15 lower ends and screw rod 14 upper end screw threads.When detecting operation, can move down by drive screw 14 through handwheel 12, make manual self-locking position-limit mechanism separate with elevating mechanism 2; Thereby can begin to detect operation, after detecting the operation completion, screw in the swivel nuts 15 through screw rod 14; The realization self-locking is spacing, avoids causing danger.
