The universal wheeled electric controlled door crane of the utility model wheelspan type variable, the technical scheme that is adopted is: comprise door frame, walking lifting appliance and the tire traveling gear be made up of girder, left and right sides curb girder and left and right sides cross sill, the walking lifting appliance is installed on the girder external orbital; The inner telescoping mechanism of forming by motor, reductor and ball-screw of installing of girder, ball-screw nut and cylindrical shape telescopic girder are fixed; Described right side beam top and girder right-hand member are fixed, and left side beam top and telescopic girder left end are fixed; The tire traveling gear is installed at cross sill two ends, the described left and right sides, and the lower-left crossbeam is installed the operator's compartment that is provided with actuation means, and the tire traveling gear is connected electrical control cubicles respectively with actuation means.
Described actuation means is made up of bearing circle, brake pedal and acceleration pedal, and bearing circle, brake pedal and acceleration pedal are connected with electrical control cubicles by circuit respectively.
Described walking lifting appliance is an electric block.Described tire traveling gear is made up of four adhesion wheels, and each adhesion wheel disposes respectively and electrical control cubicles bonded assembly steering hardware, brake equipment and Power Drive Unit.
Described girder is the single structure of box, and curb girder is made up of symmetrically arranged two oblique bending supporting legs, and oblique bending supporting leg top and girder are fixed, and oblique bending supporting leg bottom is fixed with cross sill.
The beneficial effects of the utility model are:
1, said device features rational structure, the operation maneuverability.
2, because four-wheel is driving wheel,, can not cause actual influence yet, but but can cause unsettled wheel fast idle motion even unsettled skidding of wheel is arranged.So adopt cylindrical shape telescopic girder structure, guarantee that four wheels can land simultaneously on scraggly ground.
3, realize the variation of vehicle wheel distance by scalable door frame, to satisfy of the requirement of cave depot different spans passage to universal wheeled electric controlled door crane loading and unloading operation.The girder inside of door frame is equipped with motor-reductor-ball screw framework of realizing that door frame is flexible.Above-mentioned characteristic makes the utility model can adapt to the requirement in different places, and scope of work is wide, and the place conformability is strong.
3, construction hoisting is convenient, the operating efficiency height, and lifting is accurately stable, and handling safety is reliable, can fully be satisfied with the various operating modes of handling operation in the cave depot.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The universal wheeled electric controlled door crane of the utility model wheelspan type variable, as Figure 1-3, comprise door frame, walking lifting appliance 4 and the tire traveling gear 11 formed by girder 3, left and right sides curb girder 6 and left and right sides cross sill 10, walking lifting appliance (electric block) is installed on girder 3 external orbital; The inner telescoping mechanism of forming by motor, reductor and ball-screw 5 of installing of girder, telescoping mechanism as shown in Figure 4, telescopic girder guide cylinder 16 is set in the girder 3, the telescoping mechanism of being made up of motor 15, reductor 14 and ball-screw 13 is fixed in the telescopic girder guide cylinder, ball-screw nut 12 is fixing with cylindrical shape telescopic girder 2, between girder left port and the telescopic girder guide cylinder support ring 8 is set, the cylindrical shape telescopic girder passes support ring; Described right side beam top and girder right-hand member are fixed, and left side beam top and cylindrical shape telescopic girder left end are fixed; The tire traveling gear is installed at cross sill two ends, the described left and right sides, and the lower-left crossbeam is installed the operator's compartment 1 that is provided with actuation means, and the tire traveling gear is connected electrical control cubicles 7 respectively with actuation means.The girder of illustrated embodiment is the single structure of box, curb girder is made up of symmetrically arranged two oblique bending supporting legs, two the oblique bending supporting leg tops and the girder right-hand member that are positioned at the right side are fixed, two oblique bending supporting leg bottoms that are positioned at the right side are fixed with the bottom right crossbeam, two oblique bending supporting leg tops that are positioned at the left side are fixed with cylindrical shape telescopic girder left end, and two the oblique bending supporting legs bottoms and the lower-left crossbeam that are positioned at the left side are fixed.
