Definitions

  • Laser alignment system for measuring alignment of rotating machine parts and methods for processing measurement results of a laser alignment system
  • the invention relates to a laser alignment system for measuring an alignment of rotating machine parts according to the preamble of claim 1.
  • the invention relates to a method for processing the measurement results of such a system.
  • Orientation here is primarily a check for parallelism and / or axial offset, for example, of two shafts interconnected by a coupling. With further adjustment means, the actual alignment can be made and checked by means of the laser alignment system.
  • Such systems are used wherever the exact alignment and / or measuring of machines, machine parts or other parts is necessary. They allow the measurement of offset in angle or position and / or parallelism, for example for the alignment of generators and gearboxes in wind turbines, for the alignment of machine, gear or propeller shafts or for the alignment of pumps and motors in all branches of industry.
  • Generic alignment devices typically include one or more laser measurement units mounted on the rotating machine parts and a display / operator device for configuring the measurement device and reading the measurements.
  • DE 20 2009 017 510 U1 describes a device and a method for determining the axial position of two machine spindles.
  • This device comprises a first measuring unit with a light source and an optical detector and a second measuring unit with a reflector prism.
  • the measuring units are arranged opposite one another on the machine parts such that the beam of the light source strikes the reflector prism in such a way that it is reflected in a spatially resolved manner back onto the detector arranged in the first measuring unit. From the migration of the point of incidence of the light beam on the detector during the joint rotation of the machine parts, a misalignment can be determined.
  • DE 101 09 462 A1 describes a device and a method for determining the axial position of two spindles.
  • the device comprises an optical transmitting device and an optical receiving device, which are each brought into at least three different rotational positions.
  • An evaluation unit determines from the registered impact points a circle from whose center coordinates and radius can be closed to the axis position.
  • a device for aligning machine shafts is known in which a portable computer with input device and display is provided to interrogate mechanical or optical measuring means for determining the translational and angular offset. With its optical transmitting and receiving device, the portable computer initially serves to record the relevant machine dimensions. To do this, the portable computer must be manually aligned to a center plane and held steady during the measurement.
  • the Easy-Laser system from Dalmalini has a display unit with a computer connected to the measuring units by cable or with wireless (Bluetooth) communication.
  • the display device includes a screen for displaying the measurement results and a keyboard for entering data. After the measurement, a report in PDF format with graphics and measured values can be created directly on the display device of the measuring system.
  • the measurements can be stored on a USB memory stick if desired.
  • the display device can also be connected to a computer for data exchange via the USB interface.
  • the known systems are by their individual display devices, each with its own data standards and interfaces expensive to manufacture and not combinable with each other.
  • the shaft alignment systems are each equipped with their own configuration and evaluation software, which does not allow communication with conventional terminals such as PDAs, laptops, smartphones or the like.
  • the object of the invention is to provide a cost-producible laser-view system with improved, preferably system-wide usable display and evaluation options.
  • a laser alignment system comprises at least a first laser transceiver unit and a first reflector, which are designed in a known manner.
  • the laser transceiver unit comprises an evaluation unit and a web server with a suitable network interface.
  • a suitable network interface Preferably, a LAN, WLAN or WAN network used. It is also possible to set up a peer-to-peer network that fulfills the required functionalities. The person skilled in the art can select the appropriate technology according to the requirements.
  • the web server serves to provide data of the evaluation unit with a standardized communication protocol, which can be evaluated by different, remote devices.
  • the advantages of the invention are to be seen in particular in that it is possible to dispense with the hitherto required manufacturer-specific handheld devices, because the data of the web server can be displayed with every customary internet-capable terminal in a web browser or special clients.
  • terminals for example, PDA's, tablet PCs, smartphones or laptops come into question.
  • the terminal only needs to be equipped with an Ethernet adapter, preferably a WLAN adapter, or have access to the data generated by the web server through another standard interface.
  • the web server is preferably designed as software, which are executed with the evaluation unit on a computer.
  • a Linux platform can run on the computer.
  • Such computers are currently used in the field of consumer electronics.
  • measurement results are preferably stored in a database, which is connected to the web server.
  • the web server generates dynamic pages upon request by a client, including the data stored in the database.
  • a database for example, a text file, comma-separated list or the like or a fixed memory area can be used as long as it is ensured that the web server has access to the stored measurement results.
  • the dynamic pages are preferably provided via a local intranet.
  • a connection to the Internet is possible, so that in special cases, for example, worldwide service can be made possible.
  • dynamic web pages with program modules are generated on the web server page.
  • the web server is actually a web application server.
  • the generation of database-linked websites is possible with different technologies. Examples include Pearl, CGI, ASP, PHP or JAVA. Depending on the application, the person skilled in the art will select the most suitable technology and implement it accordingly.
  • JAVA appears to be particularly suitable with JSP (Java Server Pages). It can be used in various technical operating systems and offers many advantages such as the use of the uniform, future-proof, powerful, modern and well-structured programming language Java, powerful standardized libraries, simple and fast database connection, good network capability, component technology, distributed applications, enterprise functions.
  • the programming language can also be used in the client (if, for example, HTML forms are not sufficient, for example for JTable or graphical representations).
  • a client on the terminal is preferably a standard browser in question.
  • a specially programmed client which then has to be installed on the terminal.
  • requests can be transmitted to the web server or data can also be sent.
  • the input and configuration options are analogous to the known devices.
  • the illustrated website can be constructed as well as display, operation and navigation as well as the display of conventional laser alignment systems.
