Hoisting crane belongs to a kind of of elevator machinery, be a kind ofly circulate, the machinery of intermittent moment.Hoisting crane mainly comprises lifting mechanism, operating unit, swing type mechanism, swing type mechanism and metal construction etc.Existing hoisting crane adopts single motor single oil pump engine installation to provide hydraulic oil for hydraulic efficiency pressure system, and its power is single, in case motor or oil pump damage, hoisting crane will can't be worked because running out of steam, and impact is used.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of double dynamical hoisting crane is provided, when being used to hydraulic efficiency pressure system to provide the engine installation of hydraulic oil to damage to solve existing hoisting crane, hoisting crane just can't use, the problem that impact is used.
The objective of the invention is to be achieved through the following technical solutions:
A kind of double dynamical hoisting crane, comprise base and be arranged on turntable on the described base, arm and platform are installed on the described turntable, A shape frame, lifting mechanism, swing type mechanism, electric-control system, hydraulic efficiency pressure system are installed on the described platform and are used to hydraulic efficiency pressure system that the engine installation of hydraulic oil is provided, described engine installation comprises main oil pump unit and auxiliary oil pump unit, and described main oil pump unit, auxiliary oil pump unit all link to each other with the hydraulic reservoir of hydraulic efficiency pressure system.
Further, described main oil pump unit comprises main base, main motor and main oil pump, and described main motor is installed on the main base, and it links to each other with main oil pump by lead spindle.
Further, described auxiliary oil pump unit comprises sub-mount, auxiliary-motor and auxiliary oil pump, and described auxiliary-motor is installed on the sub-mount, and it links to each other with auxiliary oil pump by the duplicate invoice axial organ.
Further, be provided with the first check valve on the connecting line between described main oil pump unit and the hydraulic reservoir, be provided with the second check valve on the connecting line of described auxiliary oil pump unit and inflow pipeline.
Beneficial effect of the present invention is, described double dynamical crane structure is simple, be easy to realize, its engine installation comprises main oil pump unit and auxiliary oil pump unit, two independent engine installations both can use together, also can be for subsequent use each other, and the successively successively starting of main motor, auxiliary-motor, thereby can effectively reduce the starting current of motor, and reduce accordingly the load request of hoisting crane to power supply grid.
