Abstract
The utility model discloses a mobile crane, comprising a lifting arm, a hydraulic winch, a control room, a crane underframe, a wheel, a traveling-crane engine, a variable speed case, a traversing mechanism and a driving seat, wherein, the variable speed case is connected with the wheel by a transmission shaft; the winch is connected with a pulley hook by a cable wire; the crane underframe is provided with a water-cooled oil tank and a lifting-arm oil jack; the lifting-arm oil jack is movably connected with the lifting arm; the two sides of the crane underframe are respectively provided with two vertical oil-jack legs; the water-cooled oil tank is connected with the oil chambers of the hydraulic winch, the lifting-arm oil jack and the vertical oil-jack legs respectively; and an oil pump is connected with the traveling-crane engine. The mobile crane can work normally by the main power and the all-hydraulic transmission without external power source, and has the advantages of less oil consumption, convenient and fast operation, safe and reliable performance, long service life and convenient maintenance. The mobile crane is suitable for civilian buildings construction and for the cargo handling in station and dock and the lifting work in workshop, and is an ideal device for lifting small-sized articles.
Description
Technical field
The utility model belongs to the hoisting crane technical field, relates to a kind of movable crane.
Background technology
The hoisting crane of prior art comprises generator set, OPS, under-carriage, wheel, driving driving engine, change speed gear box, direction machine and the operator's saddle that drives crane arm and winch work, and change speed gear box is connected with wheel by transmission shaft.The hoisting crane of this structure during work, needs external source to drive generator set work, and crane arm and winch carry out work under the drive of generator set.There are aging backward, the defectives such as energy resource consumption is big, mechanical wear is big, service life is short, the supporting waste of power of type of drive in the hoisting crane of prior art.
Summary of the invention
The purpose of this utility model is that the energy resource consumption of solution prior art is big, mechanical wear is big, service life is short, the technical matters of the supporting waste of power, and a kind of movable crane is provided, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model movable crane, comprise crane arm, winch, OPS, under-carriage, wheel, the driving driving engine, change speed gear box, direction machine and operator's saddle, change speed gear box is connected with wheel by transmission shaft, winch is connected with the coaster suspension hook by steel rope, its main points are that said winch is a hydraulic winch, under-carriage is provided with the water cooled fuel tank, crane arm oil top, crane arm oil top flexibly connects with crane arm, the both sides of under-carriage are respectively equipped with two vertical oily top supporting legs, the water cooled fuel tank by oil pump respectively with hydraulic winch, crane arm oil top is connected with the oil pocket of vertical oily top supporting leg, and oil pump is connected with the driving driving engine.
Said water cooled fuel tank is made up of fuel tank and water tank, and fuel tank places in the water tank.
The front of said under-carriage is provided with air baffle, and air baffle places the front of direction machine.
The both sides of said under-carriage are respectively equipped with guard rail.
The cross-sectional plane of said crane arm is V-shaped.
The utility model structure design novelty, reasonable by main car power, all-hydraulic transmission, need not get final product normal operation by external source, oil consumption is few, convenient to operation, adopt hydraulic winch, safe and reliable, the long service life of performance, maintenance and change part economy are convenient.This hoisting crane is applicable to the house owed by a citizen construction, also is applicable to the station, and little cargo handing of harbour and workshop are hung and started building to do, and is the ideal equipment of present building and industrial or agricultural lifting small article.
