Abstract

A hydraulic excavator 1 working in fields includes a controller 2 for measuring a working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12, storing measured data in a memory of the controller 2, and then transferring it to a base station computer 3 via satellite communication, an FD, etc. The transferred data is stored as a database 100 in the base station computer 3. The base station computer 3 reads the data stored in the database 100 for each hydraulic excavator, calculates a working time of a part belonging to each section on the basis of the working time of that section, and compares the calculated working time with a preset target replacement time interval of the relevant part, thereby calculating a remaining time up to next replacement of the relevant part and managing the scheduled replacement timing thereof. Thus, the appropriate scheduled replacement timing of parts can be determined even in a construction machine having a plurality of sections that differ in working time from each other.

Claims

1. A method for managing a construction machine, the method comprising:

a first step (S9-14, S20-24, S30-32) of measuring a working time for each of sections (12, 13, 15, 21a, 21b, 32) of a construction machine (1), and storing and accumulating the measured working time as operation data in a database (100); and

a second step (S36) of reading said operation data and calculating the scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section.

2. A method for managing a construction machine according to claim 1, wherein said second step includes steps (S60-82) of calculating, based on said read operation data, a working time of a part belonging to each section on the basis of the working time of said section, and comparing the calculated working time with a preset target repair/-replacement time interval, thereby calculating a remaining time up to next repair/replacement of the relevant part.

5. A method for managing a construction machine according to any one of claims 1 to 4, wherein said construction machine is a hydraulic excavator (1), and said sections include a front (15), a swing body (13), a travel body (12), an engine (32), and a hydraulic pump (21a, 21b) of the hydraulic excavator.

3. A method for managing a construction machine, the method comprising:

a first step (S9-14, S20-24, S30-32) of measuring a working time for each of sections (12, 13, 15, 21a, 21b, 32) in each of a plurality of construction machines (1, 1a, 1b, 1c), transferring the measured working time for each section to a base station computer (3), and storing and accumulating the transferred working time as operation data in a database (100); and

a second step (S60-82) of, in base station computer, reading the operation data regarding a particular construction machine from said database and calculating a scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section.

4. A method for managing a construction machine according to claim 3, wherein said second step includes steps (S60-82) of calculating, based on said read operation data, a working time of a part belonging to each section on the basis of the working time of said section, and comparing the calculated working time with a preset target repair/-replacement time interval, thereby calculating a remaining time up to next repair/replacement of the relevant part.

6. A system for managing a construction machine, the system comprising:

operation data measuring and collecting means (2, 404-6) for measuring and collecting a working time for each of sections (12, 13, 15, 21a, 21b, 32) in each of a plurality of construction machines (1, 1a, 1b, 1c)); and

a base station computer (3) installed in a base station and having a database (100) for storing and accumulating, as operation data, the working time measured and collected for each section,

said base station computer (3, 50, S60-82) reading the operation data of a particular construction machine from said database and calculating a scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section.

7. A system for managing a construction machine according to claim 6, wherein said base station computer (3, 50, S60-82) calculates, based on said read operation data, a working time of a part belonging to each section on the basis of the working time of said section, and compares the calculated working time with a preset target repair/replacement time interval, thereby calculating a remaining time up to next repair/replacement of the relevant part.

8. A system for managing a construction machine according to claim 6 or 7, wherein said construction machine is a hydraulic excavator (1), and said sections include a front (15), a swing body (13), a travel body (12), an engine (32), and a hydraulic pump (21a, 21b) of the hydraulic excavator.

9. A processing apparatus (3) which stores and accumulates, as operation data in a database (100), a working time for each of sections (12, 13, 15, 21a, 21b, 32) in each of a plurality of construction machines (1, 1a, 1b, 1c), reads the operation data regarding a particular construction machine from said database, and calculates a scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section.

10. A processing apparatus (3) which stores and accumulates, as operation data in a database (100), a working time for each of sections (12, 13, 15, 21a, 21b, 32) in each of a plurality of construction machines (1, 1a, 1b, 1c), reads the operation data regarding a particular construction machine from said database, calculates a working time of a part belonging to each section on the basis of the working time of said section, and compares the calculated working time with a preset target repair/replacement time interval, thereby calculating a remaining time up to next repair/-replacement of the relevant part.
