According to the technical scheme, the device comprises a hydraulic cylinder, a rubber piston is arranged in the hydraulic cylinder and is in airtight contact with the inner wall of the hydraulic cylinder, the rubber piston can slide forwards and backwards along the inner wall of the hydraulic cylinder, the rubber piston is connected with the rear end of a lead screw when the rubber piston moves forwards, the rear end of the hydraulic cylinder is connected with a hydraulic pipe, the hydraulic cylinder is in movable connection with a fixed base plate of an airframe, a locking nut is arranged in the middle of the lead screw, and the front end of the lead screw is connected to a radar cabin fixing plate through a pin.

Description

Fluid pressure type radar module opening device
Technical field
The utility model belongs to certain series aircraft radar module opening technology, for the unlatching at maintenance process series aircraft radar module.
Background technology
For certain series aircraft in ground service maintenance work due to need of work open rebecca cabin.What original radar equipment cabin opening device adopted is certain type mechanical type screw structure, and installation quality weight on body, must impose larger power when use, and present stage has not met the demand that open in certain certain type machine radar equipment cabin of series.
Summary of the invention
The purpose of this utility model is: a kind of fluid pressure type radar module opening device is provided, and highly versatile, can alleviate working strength, strengthens job security.
The technical solution of the utility model is: a kind of fluid pressure type radar module opening device, comprising:
Ram pot, in ram pot, be provided with rubber piston, described rubber piston contacts with ram pot inwall is airtight, described rubber piston can slide before and after ram pot inwall, described rubber piston is connected with leading screw rear end forward, ram pot rear end is connected with hydraulic tube, and ram pot is flexibly connected with body fixed base plate; Leading screw middle part is provided with locking nut, and leading screw front end is connected on radar module fixed head by pin.
The advantage that the utility model is created is:
1, the more former mechanical type of quality being mounted on body greatly reduces;
2, adopt fluid pressure type structure effectively to increase safety factor when radar module is opened;
3, strengthen the hydraulic screw rod adopting and increased greatly the holding capacity of screw mandrel, its versatility is strengthened greatly;
4, that personnel's the application of force is reduced is balanced for fluid pressure type result, the reducing and the safety of equipment cable of the working strength while contributing to radar equipment cabin to open.
Accompanying drawing explanation
Fig. 1 is a kind of fluid pressure type radar module of the utility model opening device structural representation;
Wherein, 1. pin; 2. rubber piston; 3. quick-release interface; 4. radar module fixed head; 5. leading screw; 6. locking nut; 7. ram pot; 8. body fixed base plate; 9. hydraulic tube.
The specific embodiment
Below the utility model is described in further details.
The utility model provides a kind of fluid pressure type radar module opening device, as shown in Figure 1, comprising:
Ram pot 7, in ram pot 7, be provided with rubber piston 2, described rubber piston 2 and airtight contact of ram pot 7 inwalls, described rubber piston 2 can slide before and after ram pot 7 inwalls, described rubber piston 2 is connected with leading screw 5 rear ends forward, described ram pot 7 rear ends are connected with hydraulic tube 9 by the quick-release plug 3 of hydraulic tube 9 front ends, and ram pot 7 is flexibly connected with body fixed base plate 8; Leading screw 5 middle parts are provided with locking nut 6, and leading screw 5 front ends are connected on radar module fixed head 4 by pin 1.
Too large in order to prevent that leading screw from swinging in ram pot, leading screw external diameter and ram pot internal diameter adaptation.
Radar module fixed head is provided with slotting ear, and leading screw front end is provided with jack, and pin, through the jack of described slotting ear and leading screw front end, is movably connected in leading screw front end on radar module fixed head.
Operation instruction:
1, radar module fixed head 4 is fixed on radar module by four screws, and body fixed base plate 8 is fixed on body by three screws, and the entirety that adjusting screw 5 and ram pot 7 form is fixed on leading screw 5 on radar module fixed head 4 by pin 1, fixed.Now leading screw 5 strokes are zero, in ram pot bottom; Hydraulic tube quick-release plug 3 is connected with ram pot 7, and it is firm to connect.
2, open after the tie point of radar module and body, open the hydraulic valve being connected with radar module opening device, rubber piston 2 and leading screw 5 under pressure, slowly stretch out from ram pot 7, drive rebecca cabin slowly to open.When radar module is slowly opened, guarantee the locking nut on leading screw 6 to fit with leading screw 5 all the time, prevent the unexpected pressure release of ram pot 7, leading screw 5 is retracted and the safety problem that causes.When rebecca cabin is opened to operating position, close hydraulic valve.Separately with strut, radar module is fixed to convenient work.
3, after hours, first locking nut 6 is unclamped, then open the pressure relief valve being connected with radar module opening device, now rebecca cabin will lean on self gravitation slowly to fall until close.Close pressure relief valve.
4. work is complete, and locking radar module and body junction, dismantle each device.
