Cantilever type tunneler whole machine test device

InactiveCN104833540AReduced probability of early failureAccurate measurementStructural/machines measurementFailure rateDrive shaft
The invention discloses a cantilever type tunneler whole machine test device, comprising a base (7), and a speed-increasing gearbox (5), a dynamometer (8), a torque and rotational speed sensor, and a control system (9). The output transmission shaft of the speed-increasing gearbox (5) is axially connected with the dynamometer. The input transmission shaft of the speed-increasing gearbox (5) is sleeved with a speed-increasing gearbox spline housing (4). The cutting mechanism (1) of the cantilever type tunneler is connected with the speed-increasing gearbox spline housing through a transition flange (2) and a universal coupling. The torque and rotational speed sensor is connected with the dynamometer, and transmits measured torque, rotational speed, and power signals to the control system. The device is simple in structure, and is reliable and practical. The device can be used for cantilever type tunneler whole machine tests and whole machine data analysis, and satisfies test requirements of cantilever type tunnelers in various models, so as to ensure accuracy of parameter measurement to manufacture high quality products. The device effectively reduces early stage failure rate of cantilever type tunnelers, reduces the number of service, and reduces service cost.

Recorder management platform-based KEY value calculation method and apparatus

The invention relates to a recorder management platform-based acceleration coordinate conversion method and apparatus, and belongs to the field of electronic map vehicle position information processing. In order to overcome the shortcoming that the operation performance of a platform is seriously influenced when a quantity of received coordinate data is relatively large because the existing recorder management platform does not have a deviation value caching function, the recorder management platform-based acceleration coordinate conversion method and apparatus is proposed. The method comprises the steps of converting to-be-processed geographic coordinates into two-dimensional rectangular coordinates; according to given precision, performing grid division on a coordinate system; solving southwest point coordinates of a grid where the coordinates are located; and combining horizontal coordinates and longitudinal coordinates of the southwest point coordinates to form a character string, which serves as a KEY value, wherein the KEY value is used for representing the coordinates of the grid where the to-be-processed geographic coordinates are located. The method and the apparatus are suitable for electronic map positioning of the recorder management platform.
