The bottom surface of the platform supporting seat 5-1 is in threaded connection with the landing platform 2, the vertical surface of the upper end of the platform supporting seat 5-1 is riveted with the platform flange 5-2, and the straight flange 5-2-1 and the bent flange 5-2-2 of the platform flange 5-2 are connected in a riveting mode.
The ramp supporting seat 6-1 is in threaded connection with the side face of the ramp ladder face 3, the vertical face of the upper end of the ramp supporting seat 6-1 is riveted with the ramp flange 6-2, and the long straight flange 6-2-1 and the outward-turning flange 6-2-2 of the ramp flange 6-2 are connected in a riveting mode.
the thickness of the platform supporting seat 5 is gradually reduced from the root to the upper end, and the middle part is provided with a cross-shaped reinforcing rib, so that the weight is reduced, and the platform supporting seat is designed to be hollow in multiple positions.
the ramp supporting seat 6 is L-shaped, the root of the ramp supporting seat 6 is uniform in thickness, the thickness of a bending part is maximum, the part from the bending part to the part connected with the ramp flange 6-2 is in a thinning trend, the force bearing configuration is good, and the two sides of the ramp supporting seat are designed in a hollow mode, so that the supporting seat is lighter in weight.
The bending flange 5-2-2 is bent downwards by 20 degrees to 30 degrees, the outward-turning flange 6-2-2 is bent downwards by 10 degrees to 30 degrees and bent outwards by 20 degrees to 30 degrees, and the interference between a suspension on the outer side of the vehicle and a carriage on the inner side of the vehicle and the corresponding flanges is prevented in the running process of the vehicle.
the length of the wheel transition guide section 7 can at least accommodate half of the wheels in the advancing process, so that the posture of the wheels has enough space to guide the posture, and the wheels smoothly enter the step transfer stage of the ramp.
the sections of the platform flange 5-2 and the ramp flange 6-2 are both right trapezoid or semicircular, when the sections are right trapezoid, four corners of the right trapezoid are all rounded, the included angle between the straight waist and the inclined waist is 10-20 degrees, the arc surface formed by the inclined waist and the upper straight surface faces the wheels, the distance between the wheels in the non-walking state and the respective side flange is 10-20mm, and the distance allows the wheels to have proper posture deviation adjustment space.
the ramp supporting seat 6-1 is made of magnesium alloy or titanium alloy.
The uncertainty of the transfer attitude of the mars can be caused by the uncertainty of the landform of the landing site and the uncertainty of the attitude of the lander, so that the transfer risk is increased. The landform uncertainty of the landing site comprises that the landing surface of the lander may be a slope surface forming a certain included angle with the local horizontal plane; the contact point of the ramp 3 with the spark surface may be a rock or a pit. The uncertainty of the attitude of the lander means that unequal compression of a plurality of landing legs can occur, so that the landing platform 2 and a landing surface have a certain inclination angle, and therefore the transfer attitude of the planet carrier 1 has uncertainty.
The working process of the group of safety guardrails is the safety protection process of the guardrails in the transfer process of the planet vehicle 1. The planet car 1 needs to go through several stages of platform 2 moving, transition transfer from the platform 2 to the ramp step surface 3, ramp step surface 3 moving and ramp step surface 3 transferring to the ground 4 in the traveling process, and the group of guardrails are all needed to play a safety protection role.
When the planet vehicle 1 starts to transfer and start on the platform 2, the planet vehicle 1 has the tendency of side shift or side tilt after being locked and released because the landing ground 4 is uneven or lands on a slope, and the guardrail on one side is in contact with the planet vehicle and limits the movement of the planet vehicle.
When the planet vehicle 1 is transferred from the platform 2 to the ramp ladder surface 3, namely, at the overlapping position of two guard rail flanges, the overlapping position is overlapped to limit the pose of the wheels, the flange of the ramp guard rail 6 is guided along the inner side necking in the traveling direction, and the platform flange 5-2 and the ramp flange 6-2 at the overlapping position are both bent downwards, so that the interference between a suspension outside the vehicle and a carriage inside the vehicle and the flanges in the traveling process of the vehicle is prevented.
When the planet vehicle 1 travels on the ramp step surface 3, the ramp flange 6-2 prevents the vehicle body from turning over; when the planet carrier 1 moves to the position between the ramp step surface 3 and the ground 4, the outward turning flange 6-2-2 at the tail end of the ramp flange 6-2 bends downwards by 10 degrees to 30 degrees and bends outwards by 20 degrees to 30 degrees, and the guide structure expands downwards and outwards, so that the transfer restriction of the planet carrier 1 is weakened, and the planet carrier can be transferred smoothly.
in addition to preventing the planet vehicle from tilting and moving, in the moving process of the planet vehicle 1, because the vehicle is generally a multi-wheel vehicle, and a plurality of wheels cannot be ensured to be in the same direction as the moving direction because the posture of the vehicle body or the state of the wheels is not controlled, when the vehicle body or the wheels are in a deviated posture, the platform flange 5-2 and the ramp flange 6-2 are in contact with the outer edge and the inner edge of the wheels to control the moving posture of the wheels; the installation intervals of the supporting seats on the retaining edges of the supporting seats are smaller than the wheel pitches of two wheels, the supporting seats are respectively adjusted in posture, and the supporting seats are not influenced by the retaining edges.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
