Background technology
Current construction machinery and equipment is at past maximization future development, arranging of driver's cab need ensure that operating personal has larger visual range when operation, such as when design has the bucket-wheel stacker reclaimer of longer arm frame, consider the visuality that driver's cab operates, usually driver's cab is arranged on jib, and the emptying point of close jib front end.Therefore, ensure that driver's cab is in horizontality all the time, namely the floor level of driver's cab is parallel to the ground, becomes the gordian technique of driver's cab design, Control and Application.Be arranged on the driver's cab on jib, in order to ensure floor level and the plane-parallel of driver's cab, traditional solution mainly contains following two kinds of forms:
One is utilize the pitching hydraulic efficiency pressure system of cantilever pitching hydraulic cylinder and a set of hydraulic proportional control apparatus, acts on a change hydraulic push rod regulating driver's cab position.Its shortcoming is that the position adjustments action of driver's cab is subordinated to cantilever pitching hydraulic efficiency pressure system, its position is realized by the ratio calculation and control that hydraulic efficiency pressure system is comparatively complicated, higher to the requirement of Installation and Debugging and maintenance, once to have bias adjustment to get up more complicated in position.
Two is the driver's cabs being with control system, has comparatively complicated control system, generally has driver's cab level attitude detecting device, electric hydraulic pressure control system, the mechanisms such as hydraulic push rod.Advantage has higher automatic regulation function and regulating power, and degree of automation is high, and real-time response is effective.Shortcoming is system complex, and a link goes wrong, and whole system may be paralysed, investment and maintenance cost high, and likely there is artificially increasing because regulating mechanism is stuck the situation that driver's cab offsets.
Utility model content
In order to overcome the defect of prior art, the technical matters that the utility model solves is: provide a kind of self-equalizing driver's cab and have the construction machinery and equipment of this driver's cab, have structure ingenious rationally, be easy to the features such as I&M.
In order to solve the problems of the technologies described above, on the one hand, the utility model provides a kind of self-equalizing driver's cab, comprises first end and is hinged on driver's cab body on cantilever; Two ends respectively with the second end of driver's cab body and hinged the first single-acting formula hydraulic actuating cylinder of cantilever; Two ends respectively with cantilever and hinged the second single-acting formula hydraulic actuating cylinder of frame; The connection pipe be communicated with the oil pocket of the second single-acting formula hydraulic actuating cylinder with described first single-acting formula hydraulic actuating cylinder; When cantilever pitching luffing, have the piston rod of to stretch out in described first single-acting formula hydraulic actuating cylinder and the second single-acting formula hydraulic actuating cylinder, the piston rod of another shrinks.
As further improvement opportunity scheme, the self-equalizing driver's cab that the utility model provides, the hinge-point at described first single-acting formula hydraulic actuating cylinder two ends to the hinge-point of driver's cab body and cantilever apart from equal; The hinge-point at the second single-acting formula hydraulic actuating cylinder two ends is equal to the distance of the pitching centre of gration of cantilever; And the hinge-point at the first single-acting formula hydraulic actuating cylinder two ends is to the hinge-point at the hinge-point distance of driver's cab body and cantilever, the second single-acting formula hydraulic actuating cylinder two ends to the distance of the pitching centre of gration of cantilever, is equal between them.
As further improvement opportunity scheme, the self-equalizing driver's cab that the utility model provides, the oil pocket of described first single-acting formula hydraulic actuating cylinder and the second single-acting formula hydraulic actuating cylinder, their sectional area is equal.
When not conflicting, above-mentioned improvement opportunity scheme can be implemented alone or in combination.
In order to solve the problems of the technologies described above, on the other hand, the utility model provides a kind of construction machinery and equipment, and it has the self-equalizing driver's cab described in aforementioned any one.
The self-equalizing driver's cab that the utility model provides, can be used for construction machinery and equipment.In cantilever amplitude changing process, the luffing of cantilever makes the piston rod of the second single-acting formula hydraulic actuating cylinder stretch out or shrink, because the oil pocket pressure of the first single-acting formula hydraulic actuating cylinder and the second single-acting formula hydraulic actuating cylinder is equal, total hydraulic pressure oil mass of two oil pockets is constant, the piston rod of the first single-acting formula hydraulic actuating cylinder is made to shrink or stretch out, the floor level of driver's cab body 1 all the time in horizontal surface, have structure ingenious rationally, be easy to the features such as I&M.
