" Code for design of steel structures " (GB 50017-2017), " the mechanical design handbook first volume ".
1, working platform data and relevant design requirement:
(1) it constructs inclined-plane (/ degree): 1:0.5 and 1:0.3 (taking gradient 1:0.5 is calculating standard)；Slope is than being mainly and scene
The slope of slope supported is than being adapted, and every section of slope supported of adaptation is adjustable.Top layer stretches out bracket I5 and middle layer stretches out bracket
I3 can be slided in top layer steelframe 1 and middle layer steelframe 1, and top layer stretches out bracket I5 and middle layer stretches out bracket I3 design and stretches out 6
Arms, the two-arm that is often connected are integrally connected using snap fit, stretch out bracket I5 in top layer and middle layer stretches out the side of bracket I3
Equipped with several through-holes, it is fixed on steelframe by pin 7 or R type pin 9 by bracket is stretched out.The protective fence and top layer of 1 top layer of steelframe
The protective fence joining place of bracket I is stretched out using being slidably connected, and so that top layer is stretched out bracket I and is stretched out and adjust.
(2) mobile platform chassis is reequiped using dumper, and body of tipper carriage size is 5.6 meters 2.3 meters of * wide long；Terrain clearance
1.3 rice；
(3) 2 meters of first layer podium level, 2 meters of second layer podium level；
(4) platform uniformly carries 300kg；
2, design & check calculates:
Fig. 5 is the Modeling Calculation carried out using software for calculation, and the simplified model that platform and vehicle carry out is calculated, is calculated
Stable state when, when how long are maximum hron spacing, i.e. cantilever, mobile trolley used entirety starts oneself unstability.
It is inputted according to design, as Fig. 5 can show that top layer platform stretches out cantilever full-size are as follows: 2735mm；
Selecting 100*100*6mm material Q235 square tube according to national standard profile is cantilever arm；It calculates below with the standard meter
It calculates.Profile section is as shown in Figure 6:
6 arms are stretched out in design, and the two-arm that is often connected is integrally connected, as shown in Fig. 7, Fig. 8, Fig. 9:
Design calculates data:
Jib-length (bracket 5/6 is stretched out at top) L=2735mm；
Profile section (bracket 5/6 is stretched out at top) 100*100*6mm；
Q235 elasticity modulus of materials E=200GPa, limit stress δ=235MPa；
Static load bearing requirements 300kg, dynamic loading m=dead load × 2=600kg.
Dynamic load load forces Fz=m*g=600*10=6000N；
Single group cantilever carries dynamic load load forces F=Fz/3=2000N；
Beam section the moment of inertia
M=F*L=2000*2735=5470000N.mm
Maximum stress
δmax82MPa is taken to be less than the limit stress of 235MPa, design is met the requirements；
Computer simulation analysis result: maximum stress 89.6MPa, end largest deformation 11.6mm < L*2/400=
13.7mm meets design requirement；
Machine gravity calculates:
As shown in Figure 10, chassis weight is calculated by 15t, and upper dress all wt is 3.4t；
Machine gravity position after upper mounting plate load 300kg manikin is as shown in Figure 10:
Assembly work component, antidumping stabilization need to meet the following conditions:
E≤b/3
In formula, e --- eccentricity, the i.e. distance of the resultant force of subgrade reaction to base center；
B --- bottom of foundation width.
Position of centre of gravity is away from base center distance e=0.14m≤b/3=2.3/3=0.77m, therefore mounting platform antidumping energy
Power meets code requirement.
