The operator's compartment of crawler crane is generally fixed, and crawler crane has work and transportation two states, and different states requires operator's compartment to have different control positioies, could help like this chaufeur to finish the work of different conditions.When work, operator's compartment is fixed on the hoisting crane side, and width is larger; During transportation, for avoiding super wide can't the transportation, need that operator's compartment is rotated to hoisting crane the place ahead and fix.Wherein, operator's compartment is fixed on the pivoted arm, and pivoted arm is connected with lifting owner platform and is rotatable, rotates the switching of realization work and travelling position around main platform thereby drive operator's compartment.
Pivoted arm commonly used and main platform fixed form support fixing for revolution now.Its pivoted arm end comprises up and down two cover plates, upper cover plate is connected with axle by plain bearing, and lower cover supports the outer ring bolt with revolution and is connected, and revolution is supported inner ring and fixed with main platform again, during the pivoted arm rotation, the ball between the Internal and external cycle is supported in revolution so that the pivoted arm rotation is flexible.This fixed form volume is larger, and cost is higher.Also have a kind of structure that adopts bearing and axle that pivoted arm is fixed, the pivoted arm end is sleeve structure, and a plain bearing respectively is equipped with in the sleeve pipe top and bottom, in the plain bearing bottom of lower end a thrust bearing is installed again.Pivoted arm is connected with main platform with the pivoted arm anchor shaft by each bearing.During the pivoted arm rotation, plain bearing can reduce the radial rotary friction, and thrust bearing can reduce pivoted arm bottom and main platform fitting surface friction, guarantees the pivoted arm flexible rotating.But because pivoted arm is cantilever beam structure, larger side direction moment is arranged between bearing and the pivoted arm anchor shaft, cause plain bearing and axle friction force larger, clamping stagnation can appear in the pivoted arm rotation.
The utility model content
Present operator's compartment pivoted arm fixed sturcture is complicated, cost is higher and pivoted arm rotates inflexible problem in order to solve, and the utility model embodiment provides a kind of operator's compartment pivoted arm fixed sturcture and hoisting crane.Described technical scheme is as follows:
A kind of operator's compartment pivoted arm fixed sturcture, comprise pivoted arm, described pivoted arm one end is fixed with operator's compartment, the described pivoted arm other end is fixed between platform upper plate and the platform floor by axle, described pivoted arm can pivot, and wherein, also includes the pivoted arm registration device, described pivoted arm registration device comprises pivoted arm adapter plate and locking mechanism, and described locking mechanism is by the fixing described pivoted arm of described pivoted arm adapter plate; On described pivoted arm and the axle that described axle is connected thrust bearing and antifriction-bearing box are installed.
Preferably, described antifriction-bearing box has two, and described thrust bearing has one, and described thrust bearing is positioned at the side near described platform floor.
Preferably, described locking mechanism is dowel bolt, on the described pivoted arm adapter plate tapped bore is arranged, and described dowel bolt is by the fixing described pivoted arm of described pivoted arm adapter plate, and described dowel bolt holds out against the side of described platform floor.
Preferably, described dowel bolt has two, and described dowel bolt is hex bolt, has through hole on six on the described dowel bolt head, and the end away from described dowel bolt head on the described dowel bolt screw rod is polished rod.
A kind of hoisting crane, described hoisting crane are equipped with above-mentioned each described operator's compartment pivoted arm fixed sturcture.
Compared with prior art, operator's compartment pivoted arm fixed sturcture and hoisting crane that technique scheme provides have following advantage: by axle and be installed in antifriction-bearing box on the axle and mode that thrust bearing cooperates is fixed pivoted arm and lifting owner platform, simple in structure, dependable performance greatly reduces cost.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
