Embodiment Construction

[0027] see Figure 1 to Figure 3The digging performance test device 30 of the excavator according to the first embodiment of the present invention includes a sensor 31 , a data acquisition system 32 and a visualization software platform 33 . The sensor 31 is used to detect limiting factors related to the overall digging force of the excavator. The data acquisition system 32 is connected with the sensor 31 and is used to calculate the digging force of the whole machine according to relevant limiting factors. The visualization software platform 33 is connected with the data acquisition system 32, and is used to import the excavation force of the whole machine, form an excavation cloud map, and evaluate the excavation performance of the excavator according to the excavation cloud map.

[0028] In the embodiment of the present invention, such as figure 2 and image 3 As shown, the sensor 31 includes: a first cable sensor 4, which is arranged on the excavator 20 and is used to ...

Abstract

The invention discloses a method and a device for testing excavation performance of an excavator. The method comprises steps that: an excavator work stroke is divided into multiple test points, restriction factors correlated with whole machine excavation force of the excavator are detected at the multiple test points through a sensor, the whole machine excavation force is calculated according to the restriction factors to form an excavation cloud chart, and the excavation performance of the excavator is evaluated according to the excavation cloud chart. Through the scheme, according to the method and the device, the excavation performance of the excavator is analyzed through an excavation cloud chart mode and a superposition method on a basis of visualization software, and whether the excavation force is reasonably performed at main excavation areas is further determined, and thereby a set of complete test data analysis evaluation system is established.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an excavator excavation performance testing method and device. Background technique [0002] Excavators are suitable for high-intensity operations and play an extremely important role in construction, mining, agriculture, water conservancy and other fields. The excavation performance of an excavator is a key indicator for evaluating the performance of an excavator, and it also has important guiding significance for the design and application of an excavator. [0003] In the prior art, most of them only calculate the excavator's bucket digging force, stick digging force and their test methods, and there are few methods for analyzing and judging the excavating performance of the entire area and main areas of the excavator. Therefore, it is necessary to propose a test and evaluation method that can more accurately and comprehensively reflect the excavation performance, so as t...
