Description
Technical field
The utility model belongs to technical field of concrete mixers, is suitable for improper ventilation construction ring more particularly, to one kind
The motor driver of the concrete mixing and transporting car in border.
Background technique
Currently, the pouring out concrete of domestic concrete mixing and transporting car is diesel engine output a part by automobile itself
Power drives hydraulic device, drives mixing drum rotation to carry out discharging, since the power of automobile is diesel engine, so unavoidably
Emission is wanted on ground, can be in spacious environmental work, but is worked in tunnel, since ventilation condition is bad in tunnel, is easy
A large amount of tail gas accumulations are formed, the health of construction personnel is seriously affected.
Summary of the invention
The purpose of this utility model is that improving the deficiency of prior art and providing a kind of using motor drive, mixer truck
In the motor driver of the good concrete mixing and transporting car of the emission-free discharge of discharge process, working environment.
The purpose of this utility model is achieved in that a kind of motor driver of concrete mixing and transporting car, is hair
Motivation is connected by transmission shaft and drives the first plunger-type fuel pump, its main feature is that motor is connected by shaft coupling drives the second Plunger oil
Pump, the oil outlet of oil cooler are separately connected the first plunger-type fuel pump of connection, the by the pipeline with oil pump suction tube three-way ball valve
The inlet port of two plunger-type fuel pumps, the first plunger-type fuel pump, the second plunger-type fuel pump the first high pressure oil port pass through it is high with the first oil pump
The pipeline of pressure pipe three-way ball valve is separately connected the first high pressure oil port of connection fixed displacement motor, and the second high pressure oil port of fixed displacement motor is logical
Cross the pipeline with the second oil pump high-voltage tube three-way ball valve be separately connected connection the first plunger-type fuel pump, the second plunger-type fuel pump second
The motor unloading port of high pressure oil port, fixed displacement motor is separately connected connection first by the pipeline with motor oil discharge pipe three-way ball valve
Second oil pump unloading port of plunger-type fuel pump, the second plunger-type fuel pump, the first oil pump emptying of the first plunger-type fuel pump, the second plunger-type fuel pump
Mouth is separately connected the oil return opening of connection oil cooler by the pipeline of oil pump oil discharge pipe three-way ball valve, and fixed displacement motor connection, which drives, slows down
Machine, speed reducer connection driving mixing drum.
Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model uses two sets
It is independent hydraulically controlled to form two sets by three-way ball valve control in parallel by shared one quantitative horse of two plunger-type fuel pumps for drive system
Drive system composition, after mixer truck ventilation condition bad working environment, such as tunnel, to unload the concrete in mixing drum
When, automobile engine stops working, and connects external power supply, starts motor, and another set of hydraulic system is driven to work, and cylinder is mixed in driving
Rotating cylinder carries out discharging to the concrete in mixing drum, makes concrete after engine stop work by motor drive mixing drum
Rotation avoids because engine operation causes exhaust emission in tunnel.
Detailed description of the invention
The utility model is described in further details with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural schematic diagram of the utility model.
In figure：1, engine, 2, transmission shaft, the 3, first plunger-type fuel pump, 4, fixed displacement motor, 5, planetary reducer, 6, stirring
Cylinder, 71, oil pump oil discharge pipe ball valve, 72, oil pump suction tube ball valve, 73, motor drain mast ball valve, the 74, first oil pump high-voltage tube ball
Valve, the 75, second oil pump high-voltage tube ball valve, 8, motor, 9, shaft coupling, the 10, second plunger-type fuel pump, 11, oil cooler.
Specific embodiment
A kind of motor driver of concrete mixing and transporting car is referring to Fig.1 that engine 1 passes through 2 connecting band of transmission shaft
Dynamic first plunger-type fuel pump 3, motor 8 drive the second plunger-type fuel pump 10 by the connection of shaft coupling 9, and the oil outlet of oil cooler 11 passes through
Pipeline with oil pump suction tube three-way ball valve 72 is separately connected inlet port P2, the second plunger-type fuel pump of the first plunger-type fuel pump of connection
Inlet port P1, the first high pressure oil port A1 of the first plunger-type fuel pump, the second plunger-type fuel pump the first high pressure oil port A2 by having
The pipeline of first oil pump high-voltage tube three-way ball valve 74 is separately connected the first high pressure oil port A3 of connection fixed displacement motor, fixed displacement motor
Second high pressure oil port B3 is separately connected the first plunger-type fuel pump of connection by the pipeline with the second oil pump high-voltage tube three-way ball valve 75
The second high pressure oil port B1, the second plunger-type fuel pump the second high pressure oil port B2, the motor unloading port T5 of fixed displacement motor is by having
The pipeline of motor oil discharge pipe three-way ball valve 73 is separately connected the second oil pump unloading port T2, the second plunger of the first plunger-type fuel pump of connection
The first oil pump of second oil pump unloading port T4 of oil pump, the first oil pump unloading port T1 of the first plunger-type fuel pump, the second plunger-type fuel pump
Unloading port T3 is separately connected the oil return opening of connection oil cooler, fixed displacement motor by the pipeline with oil pump oil discharge pipe three-way ball valve 71
4 connections drive speed reducer 5, the connection driving mixing drum 6 of speed reducer 5.
During transportation, mixing drum wants continuous average rate to rotate to concrete mixing and transporting car before reaching job location, with
Guarantee the homogenieity of concrete, engine 1 drives the first plunger-type fuel pump 3 that fixed displacement motor 4 is driven to pass through speed reducer by transmission shaft 2
5 drive mixing drum 6 to rotate, at this point, all open with the pipeline that three-way ball valve is connect with the first plunger-type fuel pump 3, simultaneously
