Description
Technical field
The present invention relates to excavator management, refers in particular to a kind of excavator intelligent maintenance maintenance system and method.
Background technology
The data display that China Construction Machinery net is provided, counts according to excavator branch of China Engineering Mechanical Industry Association, cuts
To in November, 2015,10 years recoverable amounts are 143.3 ten thousand in row.According to China Construction Machinery commerce and trade net investigation statisticses, in June, 2016
Part, 4461, excavator is sold altogether by national 27 main excavator manufacturing enterprises, and compare in June, 2015 4145 increase on year-on-year basis
Long 7.6%, hydraulic excavator market demand significantly rises.In addition, from terms of domestic economy development situation, road traffic, the energy
The aspects such as water conservancy, urbanization of villages construction are perfect not enough.Therefore, with the continuous growth of domestic excavator demand, excavate
Machine after market development space is huge.
Existing excavator equipment maintenance mode is primarily present two large problems：
1) out-of-date maintenance：Due to most of ABC underwritten in terms of business does not possess excavator maintenance, maintenance, do not press
The standard specified according to manufacturer is maintained, and is just repaired when excavator is damaged, and makes excavator miss optimal maintenance
Phase, minor issue leads to big problem.So as to cause excavator easily to break down, service life shortens, and security performance is reduced, or even
Full accident may be caused, the heavy losses on property are caused.
2) excessively maintenance：Agent in order that after-sale service profit maximization, to hold the excavator over range repaiied change part with
Repair, virtually add purchasing business expense burden, cause purchasing business that small-sized after-sale service point would rather be looked for also to be reluctant to look for agent.
And small-sized after-sale service point can carry out unavoidably erroneous judgement wrong diagnosis due to lacking professional maintainer and equipment to excavator, this is just
The badly damaged of excavator may be caused, cause fuel consumption increase, parts depreciation the problems such as accelerate, while being also unfavorable for energy-saving ring
Protect.
And to excavator related personnel excavator each using link in there is following point：
(1) excavator manufacturer (hereinafter referred to as manufacturer)
After-sales service system specification, also not well established, some small-sized after-sale services not enough in market after current excavator
Shop presence excavation machine part is idle, shoddy phenomenon, causes excavator easily to break down, and service life shortens, or even carries
Before scrap.Due to actually used excavator is not to underwrite business, and manufacturer also cannot definitely understand the real demand of user,
Product improvement is caused to lag behind the market demand, technological innovation is difficult to keep up with.
(2) excavator agent (hereinafter referred to as agent)
Operation difficult point under franchised dealer's pattern:With increasing sharply for domestic excavator demand, excavator work
Journey flight-line maintenance point gradually increases, and technology is broken with the monopolization of accessory, cause distributor's competitive pressure increasingly to increase.
Operation difficult point under traditional mode:It is long that failure makes a definite diagnosis the time, and operating cost is high, mobility of people is big, traveller is unstable
Fixed, wasting of resources etc..
(3) excavator underwrites business's (hereinafter referred to as underwriting business)
For the client for underwriting:It is difficult to equipment control, it is impossible to recognize each of equipment in time as the owner of equipment
Aspect operation conditions, causes maintenance not in time.And often maintenance cost is high for excavator equipment, needs the expense for spending great number
Equipment is maintained.
For the client of leased equipment:As the actually used person of equipment, because of the maloperation of machine handss and do not note
The routinely maintenance of heavy equipment, causes equipment easily to break down, and is delayed the engineering time limit.
(4) excavator operator (hereinafter referred to as machine handss)
From the point of view of Employment Status according to current machine handss, the mobility of machine handss is very big, and work unit is not fixed.Most machine
Handss are not fixed one excavators of operation, and machine handss are present unavoidably to be unfamiliar with to machine, and maintenance knowledge is not complete, causes misoperation
Unexpected industrial injury and device damage are caused, so as to schedule delays.
