Abstract
The utility model discloses a transitional connection device between an airborne laser scanner and an aircraft. The transitional connection device between the airborne laser scanner and the aircraft comprises a connecting plate, a laser scanner loading plate and a plurality of damper units. A plurality of damper units are fixed on the floor of the aircraft, the connecting plate is fixed on the damper units of the floor of the aircraft, the connecting plate is fixed with a plurality of damper units, and the laser scanner loading plate is fixed on the damper units of the connecting plate. The transitional connection device between the airborne laser scanner and the aircraft solves the problems of rough, disunity specifications, loose connection, poor anti-seismic effect in traditional transitional connection device and can also effectively reduce the problem of big airborne laser data error caused by loose connection and big vibration.
Description
Technical field
The utility model relates to airborne laser scanner additional connecting device technical field, the particularly transition connecting apparatus between a kind of airborne laser scanner and the aerocraft.
Background technology
When the airborne laser scanner is worked, it is a very important job that the airborne laser scanner keeps closely being connected with aerocraft, the fastening degree that connects and the quality of anti-seismic performance directly have influence on the precision of airborne laser data acquisition, so make airborne laser scanner and aerocraft keep closely being connected and increasing aseismicity by transition connecting apparatus, can improve the precision of airborne laser data acquisition, give full play to the advantage of airborne laser scanner.
At present, the use of crossing fishplate bar in the aerial photography industry is comparatively general, but the general connecting panel sheet material disunity that adopts, the bolt of rear end plate position is comparatively random, does not adopt the shock resistant damping piece, and integrated connection is not fastening, and damping effect is poor.
Development along with the airborne laser scanner technology, existing transition connecting apparatus obviously shows deficiency, be badly in need of a kind of novel connecting device of research, make the close-connected anti-seismic performance that increases simultaneously of airborne laser scanner and aerocraft, airborne laser scanner and aerocraft are combined together, closely cause greatly airborne laser scanner positioned internal system (IMU) and aircraft flight profiles curvature tolerance low with vibrations to eliminate not connect, thereby cause the large problem of airborne laser datum error.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, transition connecting apparatus between a kind of airborne laser scanner and the aerocraft is provided, solve existing connecting device connection and closely do not cause greatly airborne laser scanner positioned internal system (IMU) and aircraft flight profiles curvature tolerance low with vibrations, thereby cause the large problem of airborne laser datum error.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the transition connecting apparatus between a kind of airborne laser scanner and the aerocraft, comprise connecting panel, between the connecting panel above aerocraft floor and this aerocraft floor, be provided with several first order vibration absorption unit, be provided with several second stage vibration absorption unit between the laser scanner loading plate above described connecting panel and this connecting panel, laser scanner is installed on the laser scanner loading plate.
As preferred version, described first order vibration absorption unit bottom is fixedly mounted on the aerocraft floor.
As preferred version, vibration absorption unit bottom in the described second stage is fixedly mounted on the described connecting panel.
Compared with prior art, the beneficial effect that the utility model has is: the utility model has solved that the conventional transition connecting device is coarse, the specification disunity, connect not fastening, the problem that anti seismic efficiency is poor can effectively reduce the large problem of airborne laser datum error not fastening because connecting, that vibrations cause greatly.
Description of drawings
Fig. 1 is the utility model one example structure scheme drawing.
The specific embodiment
As shown in Figure 1, the utility model one embodiment comprises connecting panel 1, between the connecting panel 1 above aerocraft floor and this aerocraft floor, be provided with several first order vibration absorption unit 4, be provided with several second stage damping Unit 5 between the laser scanner loading plate 2 above described connecting panel 1 and this connecting panel 1, laser scanner 3 is installed on the laser scanner loading plate 2; Described first order vibration absorption unit 4 bottoms are fixedly mounted on the aerocraft floor; Vibration absorption unit 5 bottoms, the described second stage are fixedly mounted on the described connecting panel 1.
