Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the landing load buffering stand according to the present invention is done further
Detailed description.
The landing load buffering stand of the present invention is applied on lander, is used for transmitting landing cushion load.This
The buffering stand of invention is applied to the lander structure with side plate, base plate and dividing plate, at this kind of lander
In structure, side plate is connected to the periphery of base plate, and dividing plate is positioned at inside side plate, and the bottom of dividing plate is fixed on base plate
On, and the side of dividing plate is also connected with the medial surface of side plate.Generally, this kind of lander structure is polyhedron
Structure, has multiple side plate, and typically also has top board.Dividing plate is arranged on this top board, multiple side plate and the end
In the inner chamber that plate limits.
With reference to shown in Fig. 1 and Fig. 2, according to the buffering stand of the present invention include level board 1, riser 2 and
Two reinforcing plates 9.
One side of level board 1 is vertically connected to by first angle bead 3 and two the second angle beads 4
The lateral surface of land device side plate.As it is shown in figure 1, the level board in the present invention is triangular plate, its hypotenuse passes through
It is arranged in first angle bead on the upper and lower surface of this hypotenuse and the second angle bead is fixed to the outside of lander side plate
Face.In the present invention, the first angle bead and the second angle bead use angle bead structure well known in the art, are i.e. respectively provided with
First flank perpendicular to one another and the structure of the second flank.
In the present invention, as shown in Figure 5 and Figure 6, riser 2 is honeycomb plate structure.Riser 2 is in lander side
Installation site on plate lateral surface is corresponding to the dividing plate on lander side plate interior sides face.Riser 2 at least includes
One side, second side and the 3rd side.The first side of riser 2 is fixing even by two the third angle bars 5
Being connected to the lateral surface of lander side plate, the second side of riser 2 is fixedly attached to by two fourth angle bars 6
The lower surface of level board 1, the 3rd side of riser 2 is coplanar with the lower surface of lander base plate, and by taking
Contact pin 7 overlaps with lander base plate, the landing load of lander connect that interface is positioned at that riser 2 buries add
On brutal 21, and close to the position of second side.
Riser 2 is internal is embedded with the buttress brace 21 that cross section is rectangle, the setting of buttress brace 21 it should be guaranteed that:
The center line of buttress brace 21 extends through the application point of lander landing load in one direction, contrary
Side is upward through the side plate of lander and the interface point of base plate；The connection interface of the landing load of lander is positioned at
On the buttress brace 21 of riser 2 and close to the position of second side.
As it is shown in figure 5, the riser 2 in the present invention is ladder structure of right angle, the most straight waist in its first side 22,
Ji Shang base, second side 23, the 3rd side i.e. bottom 24.Rectangle buttress brace 21 is embedded in oblique waist 25
On.The burial place of the buttress brace in riser 2 need to ensure the intensity near landing load application point, simultaneously energy
Directly landing load is passed to base plate, bear by lander base plate raising buffering stand and be parallel to base plate institute
Load in plane.To this end, limit in the present invention, the center line of buttress brace 21 extends through in one direction
Cross the application point of lander landing load, in the opposite direction through side plate and the handing-over of base plate of lander
Point；The interface that connects of the landing load of lander is positioned on the buttress brace 21 of riser 2 and close to the second side
The position on limit.In the present invention, the connection interface of the landing load of lander is positioned at base 25 and oblique waist
At the delivery position of 27, and it is positioned on buttress brace 21, refer to the point 26 in Fig. 5.Certainly, buttress brace
The center line of 21 should ensure that in the opposite direction and at least can intersect with the base plate of lander.
The flank being connected with riser 2 of the third angle bar 5 is the first flank, this first flank close to riser
One end of 3rd side of 2 is provided with angle bead expansion structure, and this angle bead expansion structure is positioned at buttress brace 21
On one end of the 3rd side；Fourth angle bar 6 include the first flank of being connected with riser and with level
The second flank that plate connects；First flank of fourth angle bar 6 and first side away from riser 2 of the second flank
Angle bead expansion structure, and first flank being connected with riser 2 of fourth angle bar 6 it is provided with on the one end on limit
Angle bead expansion structure corresponding to one end close to second side of buttress brace 21；The third angle article 5 and the 4th
Angle bead 6 is perpendicular to one another and is molded integratedly.
In order to make the transmission of load continuously and preferably improve the bearing capacity of buffering stand by angle bead, such as figure
Shown in 4, in the present invention, the third angle bar 5 and connection board 2 and the water of connection board 2 and lander side plate
The fourth angle bar 6 of flat board 1 is perpendicular to one another and one-body molded.In order to landing load is directly passed by buttress brace
Pass the bearing capacity that the big angle bead of bearing capacity improves angle bead and buttress brace tie point simultaneously, the angle of this one
Bar structure is provided with angle bead expansion structure at the two ends of the buttress brace within the riser 2, and in riser 2
Inside bury rectangular beam and be joined together to form closed frame, to improve bearing capacity.In the present invention, the third angle bar
Substantially it is also adopted by right angle well known in the art angle bead structure as implied above with the third angle bar (that is, to have each other
Two vertical flanks).The width of corresponding shoulder portion only need to be widened by above-mentioned angle bead expansion structure
, as shown in Figure 4.
Two reinforcing plates 9 are arranged on the medial surface of lander side plate, and the center of two reinforcing plates is the most right
Should enter for riser to be connected the two ends on limit with side plate in the two ends of the side being connected with side plate of level board 1
Strengthen.
It is connected with the coplanar type of the lower surface of lander base plate to realize the 3rd side of riser 2, the present invention
In, one end of the 3rd side being positioned at riser 2 of the third angle article 5 is provided with reinforcement auricle 51, this reinforcement ear
Sheet 51 is connected between the first flank 52 and second flank 53 of the third angle bar 5, bonding jumper 7 also with reinforcement
Auricle 51 connects.As it is shown on figure 3, the third angle bar 5, riser 2 and lander base plate are connected by bonding jumper 7
Integral such that it is able to Landing Buffer load is directly passed to base plate.This bonding jumper uses known in this field
Structure, do not repeat at this.
