At the same time, the shield tail brush is also a consumable. According to the survey, the current shield tail brush industry has not effectively simulated the permanent deformation and wear of the shield tail brush under real construction conditions. Test equipment, so it is impossible to strictly control the shield tail brush quality, thus also laying hidden dangers to construction safety
[0003] At present, there is no effective method for measuring the working performance of shield tail brushes in the prior art

The invention provides an automatic detection device and method for the working performance of a shield tail brush. The device includes a machine base, a stepper motor set on the table of the machine base, a shield tail brush fixed to the sliding base by bolts, a laser distance measuring device, an intelligent counter, a gear set, a slurry spraying pipeline, a pressure pump, a nozzle and a digital Displaying the inclination box, and the working disk arranged on the table of the machine base. The stepping motor automatically controls its ejection length, and the multi-level contact mode between the shield tail brush and the working disc is realized through displacement control. The laser distance measuring device measures the distance from the fixed end of the shield tail brush to the working disc, and the intelligent counter records the working disc. The number of circles rotated within the set time, and the digital display inclination box measures the permanent deformation of the tail brush of the shield during the test. The device of the invention can more realistically simulate the permanent deformation and wear of the shield tail brush when the shield machine operates normally and adjusts its attitude in a complex construction environment, and can comprehensively evaluate the working performance of the shield tail brush.
Description
technical field [0001] The invention relates to the field of shield technology, in particular to an automatic detection device and method for the working performance of a shield tail brush. Background technique [0002] In recent years, the construction of my country's urban rail transit has continued to heat up, so the demand for shield machines as modern and mechanized construction equipment has also continued to grow. The shield tail brush is an important part of the shield machine to ensure construction safety and construction quality during the excavation process. At the same time, the shield tail brush is also a consumable. According to the survey, the current shield tail brush industry has not effectively simulated the permanent deformation and wear of the shield tail brush under real construction conditions. Test equipment, so it is impossible to strictly control the shield tail brush quality, thus also laying hidden dangers to construction safety. [0003] At pres...
