After two engine devices are switched by engine switching device they drive hydraulic pump (4) work. In site operation, power supply is provided and the operator is driven by the motor. In the site without power supply or in walking the operator is driven by diesel engine. The engine device is provided with low using cost, small noise, no pollution for circumstance, reliable work, simple maintenance and convenient walk. It can improve attendance rate and operation adaptability.
Description
Technical field
A kind of mixed power plant more precisely, is a kind ofly can use fuel oil, and power set that again can electricity consumption belong to the part of engineering machinery, are applicable to various engineering machinery, are particularly suitable for hydraulic crawler excavator and loader.
Background technology
Engineering machinery such as existing excavator and loader great majority adopt diesel engine as power, and intrinsic shortcoming is:
1. complex structure.The structure of diesel engine is very complicated, is with thus and comes problems such as cost height, fault rate height, working service inconvenience.
2. use cost height.Along with the exhaustion day by day of petroleum resources, diesel-fuel price constantly raises, and causes use cost very high.
3. contaminated environment.During diesel engine work very big noise is arranged, also will discharge a large amount of pollution of harmful waste gas environment.
Have engineering machinery such as a spot of excavator to adopt motor as power, shortcoming is: inconvenient walking does not have the building site of Power Supplies Condition not use yet.
Summary of the invention
The present invention's purpose provide a kind of can with fuel oil also can electricity consumption mixed power plant.These power set are made up of motor (1), diesel engine (2) and switchover apparatus (3) etc., it is characterized in that: power set are to be made of diesel engine and motor two cover power-equipments.The power set of existing excavator are a diesel engine just, increase a motor on this basis, have just constituted hybrid power.Concrete technical scheme is as shown in Figure 1: these power set are made of motor (1) and diesel engine (2) two cover power-equipments, switch by switchover apparatus (3) between the two cover power-equipments.Switchover apparatus (3) is again by a driven disc (7) and two driving disc spacing pressings (5) and (6) formation, driving disc spacing pressing (5) is connected with motor (1) by transmission mechanism, driving disc spacing pressing (6) is connected with diesel engine (2), and driven disc (7) is connected with hydraulic oil pump (4) by clutch shaft.The power of hydraulic oil pump (4) output enters hydraulic jack (9) through the control of main control valve (8), drives the work implements operation.
Technical scheme as shown in Figure 2, and adopt motor (1) and diesel engine (2) to drag two hydraulic oil pumps (14) and (4) respectively, two hydraulic oil pumps are connected in parallel, mutually noninterfere after one way valve (12), (13) isolate, the hydraulic oil of any hydraulic oil pump output is under the effect of two one way valves (12), (13), by the control of main control valve (8), enter hydraulic jack (9), drag work implements work.So do not need the switchover apparatus of machinery to switch power between the two cover power-equipments, but automatically switch by hydraulic means.Here said being connected in parallel not is that diesel engine and motor are worked simultaneously, and just a job wherein gets final product.
Because having adopted technique scheme, the present invention promptly is a kind ofly can use fuel oil, mixed power plant that again can electricity consumption is applicable to various engineering machinery, is particularly suitable for hydraulic crawler excavator and loader.When site operation, connect with the mains, drag work implements by motor, have that electric motor structure is simple, a reliable operation, advantages such as use cost is low, noise is little, free from environmental pollution, easy maintenance; On not having the building site of power supply and in the walking, just drag work implements, can guarantee that walking is convenient, also can improve the compliance of the rate of attendance and operation with diesel engine.
Description of drawings
Fig. 1---two cover power-equipments switch the dynamical system schematic diagram that only drives a hydraulic oil pump by clutch.
Wherein: (1) is motor, and (2) are diesel engines, and (3) are meant the switchover apparatus in the frame of broken lines, be a bidirectional clutch in this embodiment, (5) and (6) be two driving disc spacing pressings of clutch, wherein, the driving disc spacing pressing of clutch (5) and negative pulley wheel are an integral body, (7) be the driven disc of clutch, (8) be the hydraulic pressure main control valve, (9) are hydraulic jacks, and (4) are hydraulic oil pumps, (10) be driving belt, (11) are drive pulleys.
Fig. 2---two cover power-equipments drive the dynamical system schematic diagram of two hydraulic oil pumps respectively.Wherein: (4) and (14) all are hydraulic oil pumps, and (12) and (13) all are one way valves.
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 motor (1) and diesel engine (2).The driving disc spacing pressing (6) of diesel engine (2) and clutch is connected, motor (1) is connected by the driving disc spacing pressing (5) of transmission mechanism and clutch, transmission mechanism in this example is the band transmission, drive pulley (11) is contained on the motor reel, the driving disc spacing pressing of negative pulley wheel and clutch (5) is an integral body, connect by driving belt (10) between the two-wheeled, the driven disc of clutch (7) is connected with hydraulic oil pump by clutch shaft.
Engineering machinery becomes fixed operation equipment basically when site operation, connect with the mains, and drags work implements work by motor, and diesel engine is not worked.The power of motor (1) passes to negative pulley wheel through drive pulley (11), driving belt (10), negative pulley wheel and driving disc spacing pressing (5) are an integral body, separate with driving disc spacing pressing (6) when at this moment the driven disc of clutch (7) is with driving disc spacing pressing (5) combination.So power passes to hydraulic oil pump (4) by clutch driven disc (7), drive hydraulic oil pump work.The hydraulic oil of hydraulic oil pump output enters hydraulic jack (9) by the control of main control valve (8), drives work implements work, and this has just become the electric hydaulic work implements.This work implements can be an excavator, also can be loader, can also be other engineering machinery, and this electronic engineering machinery has that use cost is low, noise is little, do not discharge advantages such as harmful exhaust, reliable operation, easy maintenance.Can both provide power supply on the general building site, can both use motor to drag work implements as power.
On not having the building site of power supply and in the walking, just drag without motor, remove power line, drag work implements with diesel engine, at this moment the driven disc of clutch (7) separates with driving disc spacing pressing (5), combine with driving disc spacing pressing (6) simultaneously, the power of diesel engine (2) output drags hydraulic oil pump (4) work through clutch driving plate (6) and driven disc (7), and diesel powered has guaranteed that the walking of work implements is convenient and improved the compliance of operation.
Embodiment 2: as shown in Figure 2, motor (1) and diesel engine (2) drag two hydraulic oil pumps (14) and (4) respectively, do not need clutch to switch between the two cover power, diesel engine drags hydraulic oil pump (4), motor drags hydraulic oil pump (14), and two table oil parallels connection of pumps connect, mutually noninterfere after one way valve (12), (13) isolate, control by main control valve (8) enters hydraulic jack (9) again, drags work implements work.Here said parallel connection just is connected in parallel, and is not that diesel engine and motor are worked simultaneously, but according to circumstances selects a job wherein, and another is not need work.
