Description
Technical field
The utility model relates to a kind of self-propelled aerial working platform, especially relates to a kind of self-propelled aerial working flat-bed jib of cranking arm.Belong to technical field of engineering machinery.
Background technology
The self-propelled aerial working platform of cranking arm is mainly used in and builds the shipping agency industry, the port machine is made industry and construction trade etc.Mainly by chassis, turn table, jib, hang head, work bucket, go up control box, control box, driving engine, electro-hydraulic proportional valve and oil cylinder etc. are formed down.Before the utility model is made, traditional self-propelled aerial working platform of cranking arm all adopts electro-hydraulic proportional valve of an electric ratio handle drives, oil cylinder of electro-hydraulic proportional valve control promotes a jib amplitude-variation hoisting, and this connecting mode mainly has the following disadvantages:
Because the jib of this structure can only be controlled the luffing action of a jib with an electro-hydraulic proportional valve, amplitude oil cylinder and electric ratio handle, control two jibs, just need two electro-hydraulic proportional valves, two amplitude oil cylinder and two electric ratio handles to control the luffing action of two jibs respectively.Realize that two jib synchronous amplitudes hoist, just need both hands to operate two handles simultaneously, not only operation inconvenience, stability neither be fine, and cost is very high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of the self-propelled aerial working flat-bed jib of cranking arm that needs single only lever operated just energy two arm synchronous amplitudes to hoist is provided.
The purpose of this utility model is achieved in that the self-propelled aerial working flat-bed jib of cranking arm that a kind of energy two arm synchronous amplitudes hoist, comprise turn table, underarm, lower link, following interlock seat, connecting rod, upper arm, top rod, go up interlock seat and amplitude oil cylinder
The lower hinge of the axle bed on described underarm rear end and the turn table, the front end and the seat lower hinge that links down;
The upper articulation of the axle bed on described lower link rear end and the turn table, front end is with interlock seat middle and lower part is hinged down;
The described upper arm rear end and the seat upper articulation that links down, front end and last interlock seat upper articulation;
Described top rod rear portion is hinged with the seat middle and upper part of linking down near rear end, front end and last interlock seat lower hinge;
Described connecting rod lower end and underarm rear portion are hinged near rear end, and upper end and top rod rear end are hinged;
The cylinder tail and the underarm front portion of described amplitude oil cylinder are hinged, and the piston rod of amplitude oil cylinder and upper arm are hinged near rear end;
Described upper arm, top rod, go up the interlock seat and down the interlock seat constitute a parallel-crank mechanism,
Axle bed on described underarm, lower link, following interlock seat and the turn table constitutes another parallel-crank mechanism.
Principle of work
During as the amplitude-variation hoisting action, the piston rod of amplitude oil cylinder stretches out, and drives upper arm and upwards does the luffing action.Because upper arm and top rod have formed a parallel-crank mechanism by the last interlock seat and the seat that links down, so top rod and upper arm luffing abreast make progress, meanwhile, because top rod links to each other by connecting rod with underarm, underarm and lower link have also formed a parallel-crank mechanism by the axle bed on down interlock seat and the turn table, do the synchronous amplitude action that hoists so drive underarm and lower link simultaneously.
Compare with existing jib, the utlity model has following advantage:
1, generally two jibs is controlled separately owing to traditional self-propelled aerial working platform of cranking arm, so will realize that the difficulty that two arm synchronous amplitudes hoist is bigger, not only to operate two handles simultaneously with two hands, and also very high to operator's technical merit requirement, and stationarity neither be fine.The self-propelled aerial working flat-bed jib of cranking arm that the utility model adopts the energy synchronous amplitude to hoist, can hoist by two jib synchronous amplitudes of an electric ratio handle control, not only simple to operate, and luffing is steady, and normal operations workman just can operate freely.
2, traditional self-propelled aerial working platform of cranking arm just needs two apportioning valves and handle owing to the luffing to jib is control separately, and cost is quite high.The self-propelled aerial working flat-bed jib of cranking arm that the utility model adopts the energy synchronous amplitude to hoist then only needs an apportioning valve and a handle, and this just can save the 8000 yuan of left and right sides costs light.
