The operator's compartment great majority of present crawler crane its objective is the setting by this kind great circle arc glass sphere operator's compartment for fixing great circle arc glass sphere operator's compartment, enlarge the visual field of chaufeur.But, be arranged at the pitching rotating mechanism of the operator's compartment of the crawler crane on the revoliving arm at present, because the arm of force of revoliving arm is shorter, make operator's compartment when pitching, the pitching oil cylinder that is positioned at operator's compartment need bear bigger power, and pitching stability is not high, and the comfort level during driver's operation is not high.
The utility model content
The purpose of this utility model is to provide a kind of novel crawler crane to drive the pitching slewing arrangement, the turning force brachium, and pitching is stable, and safety is higher, operates comfortable.
For achieving the above object, the technical scheme that provides of the utility model is:
A kind of novel crawler crane operator's compartment pitching slewing arrangement is connected on the cant board of operator's compartment, comprises the pitching revolving joint, revoliving arm; The column of described pitching revolving joint difference described operator's compartment cant board of captive joint and described revoliving arm; Described pitching revolving joint comprises base plate, intermediate plate and side plate; Wherein, described base plate is connected with described operator's compartment cant board, and described side plate is captiveed joint with described intermediate plate, and described side plate, intermediate plate and described base plate connect by a bearing pin in regular turn.
Above-mentioned a kind of novel crawler crane operator's compartment pitching slewing arrangement wherein, is connected by 6 short bolt of rear end plates between described base plate and the described operator's compartment cant board.
Above-mentioned a kind of novel crawler crane operator's compartment pitching slewing arrangement, wherein, described short bolt of rear end plate is the six-sided head bolt of rear end plate.
Above-mentioned a kind of novel crawler crane operator's compartment pitching slewing arrangement wherein, is connected by 6 long bolt of rear end plates between described side plate and the described intermediate plate.
Above-mentioned a kind of novel crawler crane operator's compartment pitching slewing arrangement, wherein, described length fixedly spiral shell is the six-sided head bolt of rear end plate.
Above-mentioned a kind of novel crawler crane operator's compartment pitching slewing arrangement, wherein, described base plate, intermediate plate and side plate are made by aluminum alloy materials.
Above-mentioned a kind of novel crawler crane operator's compartment pitching slewing arrangement, wherein, the cross-sectional plane of described base plate, intermediate plate and side plate is circular.
A kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model, simple in structure, compact, firm and reliable connection, rotating force arm is longer, and pitching is convenient stable, operates comfortable stable, even under the situation of damage of pitching oil cylinder or inefficacy, it is firm to guarantee that also operator's compartment connects, and unlikely accident of tumbling is safe and reliable.
Description of drawings
Fig. 1 is the annexation figure of a kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model and operator's compartment;
Fig. 2 is the pitching revolving joint in the utility model and the connection diagram of revoliving arm and operator's compartment cant board;
Fig. 3 is the decomposing schematic representation of the pitching revolving joint in the utility model.
The specific embodiment
Come the utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model is connected on the cant board 00 of operator's compartment, comprises pitching revolving joint 1, revoliving arm 2.Wherein, on the column 21 of pitching revolving joint 1 difference captive joint operator's compartment cant board 00 and revoliving arm 2.As shown in Figure 3, the pitching revolving joint 1 in the present embodiment comprises base plate 11, and intermediate plate 12 and side plate 13, and base plate 11, the cross-sectional plane of intermediate plate 12 and side plate 13 are circular.Install when connecting, base plate 11 is connected with operator's compartment cant board 00 by 6 short bolt of rear end plates 14, be connected by 6 long bolt of rear end plates 15 between intermediate plate 12 and the side plate 13, last, side plate 13, intermediate plate 12 and base plate 11 are fixed together by bearing pin 16 in order.
A kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model has following advantage:
(1) the pitching revolving joint in the utility model adopts bolt, bearing pin to connect, compact conformation, simple, stable, and connection is reliable, can realize that the operator's compartment angle is the pitching of 25 degree;
(2) use of a kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model makes that the rotating force arm of operator's compartment is elongated, and the pitching action is stable convenient, operates comfortable;
(3) a kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model even under the situation of damage of the pitching oil cylinder in operator's compartment or inefficacy, also can be guaranteed the safety and firmness of operator's compartment, unlikely generation overthrow accident, safe and reliable practicality.
Should be pointed out that foregoing is the enumerating of preferred forms of a kind of novel crawler crane operator's compartment pitching slewing arrangement of the present utility model, wherein the part of describing in detail to the greatest extent is construed as with the general fashion in present technique field and is implemented.Simultaneously, for one of ordinary skill in the art, equivalent transformation and the modification in not departing from spiritual category of the present utility model the utility model done all will fall within the protection domain of claim of the present utility model.
