The specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, multiple degree of freedom operator's compartment of the present utility model comprises the car 6 that is arranged in hinged way respectively operator's compartment carriage 5 front portions and the saddle 4 that is arranged on operator's compartment carriage 5 rear portions, the principal arm 2 that one end and saddle 4 are hinged, the other end and swing arm 1 are hinged, and end and saddle 4 is hinged, the other end and swing arm 1 are hinged a pull bar 3, described pull bar 3 is installed in the mode paralleled with principal arm 2 vallecular cavity that is positioned at principal arm 2 belows; Be provided with in hinged way oscillating oil cylinder 11(referring to Fig. 7 between saddle 4 and operator's compartment carriage 5); The other end of described swing arm 1 and board main body 20 are hinged, and between swing arm 1 and board main body 20, are provided with in hinged way angling cylinder 10(referring to Fig. 2); And form parallel-crank mechanism by described swing arm 1, pull bar 3, principal arm 2 and saddle 4 in principal arm luffing plane; Be connected with in hinged way connecting panel 7 on the binding end swing arm bottom surface of swing arm 1 and principal arm 2, the two sides of the other end of described connecting panel 7 are a hinged side plate 8 respectively, and the other end of described side plate 8 is hinged on respectively two sides of principal arm 2; Connecting panel 7 forms four-bar mechanism with swing arm 1, principal arm 2 and side plate 8 in principal arm luffing plane; Be provided with amplitude oil cylinder 9, the other end of amplitude oil cylinder 9 and principal arm 2 hinged (referring to Fig. 2) at connecting panel 7 and side plate 8 binding ends; The hinge of described swing arm 1 and principal arm 2 and pull bar 3 is the vertical relation of line up and down in principal arm luffing plane.
As shown in Figure 3, be provided with in hinged way fine setting oil cylinder 12 between described operator's compartment carriage 5 and car 6.
Principle of work of the present utility model is as follows:
As shown in Figure 2, when operator's compartment is in initial condition, start angling cylinder 10, after making operator's compartment turn to suitable angle in horizontal surface (Fig. 4), start amplitude oil cylinder 9, principal arm 2 in perpendicular downwards luffing to ground (Fig. 5), the chaufeur car 6 of can easily entering into from ground, then under the effect of amplitude oil cylinder 9, principal arm 2 makes progress luffing to end position (Fig. 6) in perpendicular.In this process, because swing arm 1, principal arm 2, pull bar 3 and saddle 4 form parallel-crank mechanism in the luffing plane of principal arm, and swing arm 1 respectively with the hinge line of principal arm 2 and pull bar 3 in principal arm luffing plane straight down, so saddle 4 remains and moves up and down in whole amplitude changing process, to such an extent as to car 6 remains level in amplitude changing process.
Start oscillating oil cylinder 11, can carry out the fine setting (Fig. 7) in plane of rotation to car 6 in the situation that principal arm 2 positions are motionless; Start fine setting oil cylinder 12, can carry out the fine setting (Fig. 8) in the luffing scope to car 6 in the situation that principal arm 2 positions are motionless, (particularly the hanging that rises in construction machinery and equipment is carried process to the requirement at the elevation angle to adapt to chaufeur, chaufeur will constantly stare at and hang loading, along with the slowly rising of hanging loading, the elevation angle is increasing, and suitably fine setting meets the human oriented design principle).
The foregoing is only preferential embodiment of the present utility model, but do not limit the enforcement extension that the utility model is created.All unsubstantialities of having done on the basis of this embodiment are created, and protected by the utility model.
