The purpose of the invention can realize by following technique measures:
Multiple degree of freedom operator's compartment of the present invention comprises the car that is arranged in hinged way respectively the operator's compartment bracket front part and is arranged on the saddle at operator's compartment carriage rear portion, the principal arm that one end and saddle are hinged, the other end and swing arm are hinged, and end and saddle is hinged, the other end and swing arm are hinged a pull bar, described pull bar is installed on the vallecular cavity that is positioned at the principal arm below in the mode that parallels with principal arm; Between saddle and operator's compartment carriage, be provided with in hinged way oscillating oil cylinder; The other end of described swing arm and board main body are hinged, and are provided with in hinged way angling cylinder between swing arm and board main body; And in principal arm luffing plane, consist of parallel-crank mechanism by described swing arm, pull bar, principal arm and saddle; Be connected with in hinged way connecting panel on the binding end swing arm bottom surface of swing arm and principal arm, the two sides of the other end of described connecting panel are a hinged side plate (8) respectively, and the other end of described side plate is hinged on respectively two sides of principal arm; Connecting panel and swing arm, principal arm and side plate consist of four-bar mechanism in principal arm luffing plane; Be provided with amplitude oil cylinder at connecting panel and side plate binding end, the other end and the principal arm of amplitude oil cylinder are hinged.
The hinge of swing arm described in the present invention and principal arm and pull bar is vertical up and down line relation in principal arm luffing plane; Be provided with in hinged way the fine setting oil cylinder at described operator's compartment carriage and car.
Beneficial effect of the present invention is as follows:
Because the present invention has adopted a kind of parallel-crank mechanism, makes car be in all the time horizontality in amplitude changing process; The employing of luffing four-bar mechanism has improved the luffing scope; Angling cylinder, oscillating oil cylinder and fine setting oil cylinder make whole operator's compartment that larger angular field of view be arranged.

The specific embodiment
The present invention 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 invention 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 on the vallecular cavity that is positioned at principal arm 2 belows in the mode that parallels with principal arm 2; Between saddle 4 and operator's compartment carriage 5, be provided with in hinged way oscillating oil cylinder 11(referring to Fig. 7); The other end of described swing arm 1 and board main body 20 are hinged, and are provided with in hinged way angling cylinder 10(referring to Fig. 2 between swing arm 1 and board main body 20); And in principal arm luffing plane, consist of parallel-crank mechanism by described swing arm 1, pull bar 3, principal arm 2 and saddle 4; 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 consists of 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 vertical up and down line relation in principal arm luffing plane.
As shown in Figure 3, be provided with in hinged way fine setting oil cylinder 12 at described operator's compartment carriage 5 and car 6.
Principle of work of the present invention is as follows:
As shown in Figure 2, when operator's compartment is in initial condition, start angling cylinder 10, make operator's compartment in horizontal surface, turn to (Fig. 4) after the suitable angle, 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 consist of 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 in whole amplitude changing process and moves up and down, to such an extent as to car 6 remains level in amplitude changing process.
Start oscillating oil cylinder 11, can carry out fine setting (Fig. 7) in the 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 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 the 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 above only is preferential embodiment of the present invention, but does not limit the enforcement extension of the invention.The unsubstantiality that all have been done on the basis of this embodiment is created, and protected by the present invention.
