Comprehensive testing equipment for hydraulic components of tunnel boring machine

Abstract

The invention belongs to the technical field of performance detection of hydraulic components and provides comprehensive detection equipment for hydraulic components of a tunneling machine. The comprehensive detection equipment for the hydraulic components of the tunneling machine comprises a small pump detection bench (1), a big pump detection bench (2), a PLC (Programmable Logic Controller) and operation panel (3), a comprehensive valve bank (4), a valve block detection platform (5) and a hydraulic oil tank (7); the small pump detection bench is used for detecting a hydraulic pump with the displacement being less than 200ml; the big pump detection bench (2) is used for detecting a hydraulic pump with the displacement being less than 750ml and more than 200ml and detecting a hydraulic motor with the displacement being not more than 500ml; the valve block detection platform comprises a test-subjected valve block connecting block (19), an oil collecting tank (20), an instrument display panel (18) and a loading device (21). According to the comprehensive detection equipment provided by the invention, the performances of pumps, motors and hydraulic valves in a hydraulic transmission system of the tunneling machine can be detected by one piece of detection equipment.

Description

technical field [0001] The invention belongs to the technical field of performance detection of hydraulic components, and mainly relates to a comprehensive detection device for hydraulic components of a tunnel boring machine. Background technique [0002] Tunnel boring machine includes two types of shield machine TBM. The structures of the two types of mechanical equipment are different, and their functions are slightly different, but the hydraulic components used in them are basically the same; there are many hydraulic components used in tunnel boring machines, but there are still many hydraulic components in the industry. There is no special testing equipment for the hydraulic components of tunnel boring machine equipment, and none of the hydraulic testing equipment on the market can realize the testing of all hydraulic components on a tunnel boring machine, which makes the testing procedures of many hydraulic components of tunnel boring machines more cumbersome.
