Abstract
The utility model discloses an oil and electricity dual-purpose power system of a crawler-type hydraulic excavator, which includes a diesel power system and an electric power system that share one high-pressure stop valve (4). The electric power system includes a power source lead-in port (1), a control system (2) and a main motor (3), wherein the main motor (3) drives a hydraulic pump; the control system (2) includes a transformer, an air-break switch, a motor speed regulator, a motor starter and a leakage protector; a 24V lighting circuit, a 220V air-conditioner motor circuit and a 380V hydraulic cooling motor circuit are also output from the control system (2); and the high-pressure stop valve enables any one of the two power systems to work independently. During modification of the conventional combustion engine power crawler-type hydraulic excavator, the structure of the combustion engine power system requires no modification, and only circuit facilities such as motors are required to be mounted additionally.
Description
Technical field
The utility model relates to the crawler hypraulic excavator dynamical system, i.e. crawler hypraulic excavator oil, electric dual-purpose dynamical system.
Background technology
Crawler hypraulic excavator belongs to engineering machinery, take diesel oil as fuel, makes machine work with the internal combustion engine drive hydraulic pump, and power is strong, and fuel consumption is large.Along with diesel-fuel price goes up, also when the river rises the boat goes up for the excavator job costs, the inconvenience of diesel oil transportation simultaneously.Sensible each the remote mountain area of present electric power, electricity consumption is convenient, and people wish to use the work of driven by power crawler hypraulic excavator, with Cost reduction.
The utility model content
For the problems referred to above, the utility model provides a kind of crawler hypraulic excavator oil, electric dual-purpose dynamical system.
The utility model is achieved in that crawler hypraulic excavator oil, electric dual-purpose dynamical system, comprises diesel, also has one group of electric power, two groups of dynamical system common high voltage stop valves.Electric power comprises electric power incoming line mouth, control system, main motor; Main motor-driven hydraulic pumps.Control system comprises transformer, air switch, machine governor, motor starter, earth leakage protective device.Also export 24V lighting circuit, 220V air conditioner motor circuit, the cooling motor circuit of 380V hydraulic pressure from control system.
Beneficial effect: oily, electric dual-purpose dynamical system is to increase by one group of electric power on former crawler hypraulic excavator combustion engine powered basis, and high-pressure stop valve makes arbitrary group of two groups of power to be worked independently.In the former combustion engine powered crawler hypraulic excavator process of transformation, combustion engine poweredly need not to change any structure, as long as and install the circuit facility such as motor additional.Electricity consumption is used as power and makes cost greatly reduce.
Description of drawings
Accompanying drawing is crawler hypraulic excavator oil, electric dual-purpose dynamical system schematic diagram.1 electric power incoming line mouth, 2 control systems, 3 main motors and hydraulic pump, 4 high-pressure stop valves, 5 are that 24V lighting circuit, 6 is that 220V air conditioner motor circuit, 7 is the cooling motor circuit of 380V hydraulic pressure, 8 internal combustion engines, 9 internal combustion engine hydraulic pumps.10 body work.
The specific embodiment
In one group of electric power of former combustion engine powered crawler hypraulic excavator assembling, two groups of dynamical system common high voltage stop valves 4, high-pressure stop valve makes arbitrary group of two groups of power to be worked independently, and also can use simultaneously two kinds of power.Electric power comprises electric power incoming line mouth 1, control system 2, main motor 3; Main motor 3 drives hydraulic pump.Control system 2 comprises transformer, air switch, machine governor, motor starter, earth leakage protective device.Also export 24V lighting circuit, 220V air conditioner motor circuit, the cooling motor circuit of 380V hydraulic pressure from control system 2.This system adopts diesel engine Engine driven Hydraulic Pump and three-phase alternating current general-purpose machine to drive hydraulic pump, passes through high-pressure and hydraulic. and oily converter is that high-pressure stop valve works independently arbitrary group of power of two groups of dynamical systems or two groups of power provide the work of power drive excavator simultaneously.Implement more specifically: power cable enters the three-phase alternating current circulator by the base entrance hole, and circulator is comprised of alloy conductive ring, carbonaceous contact, contact holder, insulation crust.The major function of circulator is to make excavator any rotation when work not limited by cable; Cable is through the circulator metering-in control system, and control system is comprised of motor starter, machine governor, transformer, air switch, leakage relay.Play protection motor, starter motor, block power supply.The rotating speed of motor, radiating motor, air conditioner motor, light is system's control thus all; This system is placed in seat rear in driver's cabin; Be convenient to observe, check, keep in repair.Power adopts general-purpose machine directly to drive hydraulic pump by terminal pad; The high-pressure work hydraulic oil that hydraulic pump produces and low voltage operated hydraulic oil input hydraulic pressure oil exchange system; Exchange system is comprised of high pressure valve and electromagnetic switch.Its main task is that working solution force feed guiding distributing valve is started excavator work.Prevent that the working solution force feed from flowing in out-of-work internal combustion engine interlock oil pump (or motor linkage oil pump); Form circulation.Cooling system is comprised of electric fan, guide duct.Its kinetic energy is to be the hydraulic oil cooling.When internal combustion engine quits work; Its compressor of air conditioner also quits work.This system adopts a little separate type domestic air conditioning; By the transformer transformation; Be down to 220 volts with 380 volts; 24 volts two grades, 220 volts are used as air-conditioning; 24 volts are used as illumination; Guarantee safety.
