Abstract
The invention relates to a hydraulic excavator, in particular relates to a hydraulic excavator which can be driven by oil and electricity, belonging to engineering machinery. The hydraulic excavator is suitable for earthwork evacuation work for various constructed sites. A power device of the excavator consists of two sets of power equipment, namely a motor (1) and a diesel engine (4), wherein the two sets of power equipment are switched by a bidirectional clutch (6) and then drive a hydraulic oil pump (9) to work; and the motor (1) and the diesel engine (4) can be respectively used for driving two hydraulic oil pumps to work in parallel. During working on the site, a power supply is switched on; the motor drives the excavator to work; and under the conditions that no power supply exists on the site and the excavator travels, the diesel engine drives the excavator to work. The excavator has the advantages of being low in using cost, low in noise, less in waste gas emission, reliable in working, convenient and easy to maintain and travel and the like; and the attendance rate can be increased, and the working adaptability is improved. The oil-electricity hybrid technology can be also used for engineering machinery such as a loader.
Description
Technical field
A kind of hydraulic crawler excavator; More precisely, be a kind of hydraulic crawler excavator of dual-use with gasoline and electricity, belong to engineering machinery; Be applicable to the cubic metre of earth and stone digging operation of building sites such as mine, traffic, water conservancy, airport, harbour and real estate, also can be used for engineering machinery such as loader.
Background technology
Excavator is a main engineering machinery in exploitation and the excacation, and 70% work is all accomplished by excavator in these engineerings.The tradition excavator adopts diesel engine as power, and intrinsic shortcoming is:
1. use cost is high.Along with the scarcity day by day of petroleum resources, diesel-fuel price constantly raises, and causes use cost increasingly high.
2. contaminated environment.During diesel engine work very big noise is arranged, also will discharge a large amount of pollution of harmful waste gas environment.
3. complex structure.The structure of diesel engine is very complicated, has high, the problems such as the rate of attendance is low, working service inconvenience of fault rate.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can use the excavator that oil also can electricity consumption.This excavator is made up of power set, equipment, slew gear, operating mechanism, transmission system, walking mechanism and auxiliary equipment etc., it is characterized in that: power set are to be made up of diesel engine and motor two cover power-equipments.The power set of existing excavator are a diesel engine, increase a motor on this basis, have just constituted the fuel and electric hybrid excavator, and concrete technical scheme is as shown in Figure 1.The power set of this excavator are made up of motor (1) and diesel engine (4) two cover power-equipments, switch through bidirectional clutch (6) between the two cover power-equipments.Bidirectional clutch (6) is made up of a driven disc (5) and two driving disc spacing pressings (2), (3) again, and driving disc spacing pressing (2) is connected with motor through transmission mechanism, and driving disc spacing pressing (3) is connected with diesel engine, and driven disc (5) is connected with hydraulic oil pump (9) through clutch shaft.
Description of drawings
Fig. 1---two cover power-equipments switch the dynamical system sketch map that only drives a hydraulic oil pump through clutch.Wherein: (1) is motor, and (4) are diesel engines, and (6) are clutches; (2) and (3) be two driving disc spacing pressings of clutch, wherein, the driving disc spacing pressing of clutch (2) and negative pulley wheel are an integral body; (5) be the driven disc of clutch, (7) are the hydraulic pressure main control valves, and (8) are hydraulic jacks; (9) be hydraulic oil pump, (10) are driving belts, and (11) are drive pulleys.
Fig. 2---two cover power-equipments drive the dynamical system sketch map of two hydraulic oil pumps respectively.Wherein: (1) is motor, and (4) are diesel engines, and (9) and (14) all are hydraulic oil pumps, and (12) and (13) all are one way valves, and (7) are the hydraulic pressure main control valves, and (8) are hydraulic jacks.
The specific embodiment
Embodiment 1: as shown in Figure 1, this example is that two cover power-equipments drive a hydraulic oil pump, and this two covers power-equipment is meant diesel engine (4) and motor (1).The driving disc spacing pressing (3) of diesel engine (4) and clutch is connected; Motor (1) is connected through the driving disc spacing pressing (2) of transmission mechanism and clutch; Transmission mechanism in this example is the band transmission, and driving wheel (11) is contained on the motor reel, and the driving disc spacing pressing of follower and clutch (2) is an integral body; Connect through driving belt (10) between the two-wheeled, the driven disc of clutch (5) is connected with hydraulic oil pump (9).
Excavator launches supporting leg when site operation, become the implement that is completely fixed, and connects with the mains, and drags excavator work by motor, and diesel engine is not worked.The power of motor (1) passes to negative pulley wheel through drive pulley (11), belt (10), and follower and driving disc spacing pressing (2) are an integral body, separates with driving disc spacing pressing (3) when at this moment the driven disc of clutch (5) combines with driving disc spacing pressing (2).So power passes to hydraulic oil pump (9) through clutch driven disc (5), drive hydraulic oil pump work.The hydraulic oil of hydraulic oil pump output gets into hydraulic jack (8) through the control of control valve (7), drives excavator work, and this has just become the electric hydaulic excavator.The electric hydaulic excavator has that use cost is low, noise is little, do not discharge advantages such as harmful exhaust, reliable operation, easy maintenance.On the general building site power supply can both be provided, can both use motor to drag excavator work as power.
On not having the building site of power supply and in the walking; Just drag without motor; Remove power line, drag excavator work with diesel engine, at this moment the driven disc of clutch (5) combines with driving disc spacing pressing (3) when separating with driving disc spacing pressing (2); The power of diesel engine (4) output drags hydraulic oil pump (9) work through clutch driving plate (3) and driven disc (5), and diesel powered has guaranteed that the walking of excavator is convenient and improved the compliance of operation.
Embodiment 2: as shown in Figure 2, motor (1) and diesel engine (4) drag two hydraulic oil pumps (9) and (14) respectively, do not need clutch to switch between the two cover power; Diesel engine drags hydraulic oil pump (9); Motor drags hydraulic oil pump (14), and two table oil parallels connection of pumps connect, the mutually noninterfere after one way valve (12), (13) isolate of the hydraulic oil of hydraulic oil pump output; Control through hydraulic control valve (7) gets into hydraulic jack (8) again, drags excavator work.Diesel engine and motor do not need to work simultaneously generally speaking, but according to circumstances select a job wherein.
