As shown in Figure 1, Figure 2, Figure 3 shows: the bearing wheels 1 of existing monorail crane transport girder system system are installed on lifting roof beam structure by screw
4 left and right sides, enable whole system to horizontally slip on the track 3 operation.Hydraulic motor 2 is connected by screw to speed reducer 9,
Speed reducer 9 is connect by bolt with lifting roof beam structure 4, and pull rod 5 is connect using bolt with lifting roof beam structure 4, and hydraulic control valve 6 uses spiral shell
Bolt is fixed on pull rod 5.Run hydraulic motor 2 and speed reducer 9 by operating hydraulic control valve 6, speed reducer 9 has made chain sling 7
It runs up and down, drives 8 raising and lowering of suspension hook, realize hoisting function.
It lifts by crane hydraulic system and monorail crane locomotive auxiliary control hydraulic system shares a hydraulic pump, operated by reversal valve
Switching.
10 monorail crane power batteries are 9 inverter supplies, and 8 control centres are changed by logic analysis to 9 frequency converters and 3 electromagnetism
To valve signal, the positive and negative rotation of 7 Electric Machine at Pumping Station and the movement of 3 solenoid directional control valves are controlled.7 Electric Machine at Pumping Station are connect with 1 hydraulic oil pump, are led to
Crossing 7 motors drives 1 hydraulic oil pump to provide a system to hydraulic power, switches the operation of monorail crane locomotive by 2 solenoid directional control valves
State and lifting state, when in operating status give 3 monorail crane auxiliary hydraulic system feed flows, when in lift by crane state to 4 lift by crane
Reversal valve feed flow realizes that the positive and negative rotation of 5 hydraulic motors acts by the movement of 4 lifting reversal valves.
Above structure using hydraulic system as the dynamical system of medium, especially lead by the electricity of power source of battery by low efficiency
Draw on monorail crane locomotive, problem is particularly pertinent and obvious.
Summary of the invention
In order to solve hydraulic hoisting ineffective systems, hydraulic hoisting system and locomotive assisting system shared power source, two
Person cannot work at the same time, the problem of environmental suitability difference, and the present invention proposes that a kind of electrical haulage monorail crane electricity drives lifting transport girder system
System.
A kind of electrical haulage monorail crane electricity drives lifting transport girder system system, including lifting roof beam structure, speed reducer, driving motor, pull rod,
Frequency converter, hydraulic oil pump, auxiliary hydraulic system, power battery, plays chain sling, suspension hook, track at control centre, and bearing wheels pass through spiral shell
Nail is installed on the arranged on left and right sides of lifting roof beam structure, and bearing wheels horizontally slip operation in orbit.
Lifting motor is connected by screw to speed reducer, and speed reducer is connect by bolt with lifting roof beam structure, and pull rod uses spiral shell
Bolt is connect with lifting roof beam structure.Speed reducer has connected chain sling, lifts by crane chain link suspension hook.Cable gives lifting motor power supply, drives lifting
Motor and speed reducer operation, speed reducer run chain sling up and down, drive suspension hook raising and lowering, realize lifting function
Energy.
Tackling system is not interfered, the two can be worked at the same time with monorail crane locomotive auxiliary hydraulic system using independently-powered.
Monorail crane power battery gives hydraulic power unit frequency converter and lifting inverter supply respectively, passes through control centre's logic point
It analyses and gives lifting inverter control signal, control hydraulic power unit motor and lifting motor forward and backward.Hydraulic pump and hydraulic power unit electricity
Machine connection provides power to monorail crane auxiliary hydraulic system.Lifting motor is connect with speed reducer, is provided to lifting transport beam dynamic
Power.
The present invention replaces the improved efficiency of hydraulic motor realization tackling system using motor；
Using independently-powered, do not interfere with monorail crane locomotive auxiliary system, the two can work at the same time
It has the advantage that compared with prior art；
Working efficiency is promoted, and especially using battery as the single track crane system of power, increases locomotive cruising ability.
