The specific embodiment
Core of the present utility model provides a kind of displacement device, can realize moving up and down of control cabin, makes things convenient for personnel to pass in and out the change location expansion staff visual field that control cabin has increased control cabin simultaneously.Another core of the present utility model provides a kind of hoisting crane that comprises above-mentioned displacement device.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is displacement device and the control cabin annexation scheme drawing in a kind of specific embodiment provided by the utility model, Fig. 3 for displacement device shown in Figure 2 control cabin is rotated forward and move down after the location status scheme drawing.
As shown in FIG., displacement device provided by the utility model comprises the four-bar linkage and first transmission device 6, four-bar linkage comprises pivotally attached Rack Body 7, last the frame linking body of rod 9, connecting rod body 10 and the following frame linking body of rod 8 successively, between Rack Body 7 and turntable 5, be connected with first transmission device 6, first oil cylinder 12 is set between the last frame linking body of rod 9 and the Rack Body 7, and connecting rod body 10 is connected with control cabin 11.Certainly, also first oil cylinder 12 can be arranged at down between the frame linking body of rod 8 and the Rack Body 7, all can as long as satisfy the basic function of drive link body 10 upper and lower displacements.
Under the driving of first transmission device 6, four-bar linkage can drive control cabin 11 and do horizontally rotating with respect to turntable.Here first driving device 6 can be a rotary actuator, and the output shaft of rotary actuator is connected with Rack Body 7, can drive four-bar linkage by rotary actuator and do with respect to turntable and horizontally rotate.Also can adopt worm-and-wheel gear of the prior art, can also be that other can realize driving the mechanism that four-bar linkage horizontally rotates with respect to turntable.The variation of the front and back position of control cabin 5 is exactly to horizontally rotate by the front and back with respect to turntable that displacement device provided by the utility model is realized among Fig. 2 and Fig. 3.
It is to be noted, adopt rotary actuator to be better than the available technology adopting worm-and-wheel gear as transmission device as first transmission device, this be because, adopt the worm-and-wheel gear machine members bigger, and driving force is not enough to drive the rotation of main equipment, and can not satisfy the scantling of structure requirement of car load, adopt rotary actuator can overcome above-mentioned defective, it is convenient to use.
The principle of work of above-mentioned displacement device is, by controlling the flexible of first oil cylinder 12, the change in location of the frame linking body of rod 9 or the following frame linking body of rod 8 realizes the mass motion of four-bar linkage in the drive, and then drives the upper and lower displacements of control cabin 11 in perpendicular by connecting rod body 10.Particularly, when rising on the position that needs control cabin 11, stretch out first oil cylinder 12; And when needing control cabin 11 positions to descend, as shown in Figure 3, first oil cylinder 12 of withdrawing.Control cabin 11 can rise and decline scope, depends on the collapsing length of oil cylinder and the size relationship of each member of four-bar linkage.In fact, according to the difference of the collapsing length of first oil cylinder 12, four-bar linkage can be controlled at control cabin 11 diverse location of vertical plane, has increased the change in location of control cabin 11, has enlarged staff's field range.
