Abstract
The invention relates to an air conditioning system of a dual-power tire crane. The air conditioning system comprises a frequency converter, a main motor, a pressure regulating pump, a one-way valve, a control valve, a working motor, a secondary motor, an air conditioning pump and an air conditioning motor, wherein the power acquired by the frequency converter from the exterior is input to the main motor and the secondary motor through cables respectively; electric energy is converted into mechanical energy by the main motor, the mechanical energy is converted into hydraulic power through the pressure regulating pump and the one-way valve, and after being controlled through the control valve, the hydraulic power enters the working motor to output mechanical energy to operate; the secondary motor converts the electric energy into mechanical energy, the mechanical energy is then converted into hydraulic power through the air conditioning pump and the one-way valve, and the hydraulic power enters the air conditioning motor to drive the air conditioning system to work. The air conditioning system is specially designed for a hybrid-power tire crane using electric energy and diesel oil; by using the system, the energy consumption in a standby state is greatly reduced when the tire crane works with the electric energy, and the energy saving effect is very obvious.

Background technology
At present, by the discovery of researching and analysing to the energy-saving effect of existing double dynamical tire formula hoisting crane, while using power mode operation due to double dynamical tire formula hoisting crane, what adopt is control and the power mode identical with the oily drive pattern of original use, identical while pretending electrical motor for power output with use driving engine, be continuous running, and empty wagons etc. are bide one's time, the output effective power of electrical motor is lower, and the energy consumption keeping on the go is but not low; So not only there is the problem of energy dissipation, also easily make the parts over-running in its system, reduce service life, and easily cause safety misadventure.
Therefore, provide a kind of simple in structure, reasonable in design, apply easy, performance safety is reliable, the significant double dynamical tire hoisting crane a/c system of effect, the improvement of mode and power mode when to open drive, further improves the energy-saving effect of double dynamical tire hoisting crane; It is one of these those skilled in the art problem that should address.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of simple in structure, reasonable in design, performance safety is reliable, applicability is strong double dynamical tire hoisting crane a/c system is provided.
The technical solution adopted in the present invention is for achieving the above object: a kind of double dynamical tire hoisting crane a/c system, and this system includes frequency converter, main motor, pressure regulating pump, check valve, control cock, work motor, auxiliary-motor, air conditioning pump and work motor; Described frequency converter is that two-way output connects respectively main motor and auxiliary-motor, and described main motor is connected with pressure regulating pump, and pressure regulating pump is connected with work motor by check valve, control cock; Described auxiliary-motor is connected with air conditioning pump, and air conditioning pump is connected with air-conditioning motor.
The invention has the beneficial effects as follows: described a/c system is independently, when main motor is unloaded in operation, can power-off out of service, save the energy; By auxiliary-motor, drive separately a/c system, avoided the continual operation of main motor; Be beneficial to simultaneously and realize fork truck fork and the soft function that contacts operation of workpiece.Adopt double dynamical tire hoisting crane low energy consumption air conditioner system, can make wheel-mounted crane when using electric energy work, be greatly reduced in the energy consumption under readiness for action, reach energy-conservation effect.
Effect of the present invention is that double dynamical tire hoisting crane is when operation; main motor and auxiliary-motor are worked simultaneously; the power that main motor is responsible for equipment provides; auxiliary-motor is specially for a/c system provides power; when wheel-mounted crane is during in light condition; main motor is in stopped status, and to save the energy, auxiliary-motor continuous firing provides power for a/c system simultaneously.
This entire system is simple in structure, reasonable in design, efficient energy-saving, and performance safety is reliable, easy to use, makes production model hommization more, practical function highly significant.
Accompanying drawing explanation
