Abstract

The invention discloses a double-cylinder synchronous radial loads testing device, and belongs to hydraulic cylinder performance detecting equipment. The device comprises a mounting rack; two tested oil cylinders, oppositely arranged in parallel, are fixed on the mounting rack through fixing devices; a loading device is connected between piston rod ends of the two tested oil cylinders; and the piston rod ends of the two tested oil cylinders are connected with synchronous detecting devices. The device is simple in principle and structure and lower in design and production cost; through controllable loading of loads, the product use working conditions are simulated to the greatest extent; and the mounting rack is high in compatibility and suitable for most existing oil cylinders with synchronization requirements and higher lateral load working conditions.

Description

technical field [0001] The invention relates to hydraulic cylinder performance testing equipment, in particular to a double-cylinder synchronous radial load testing device. Background technique [0002] With the increasing development of urban rail transit, it brings great opportunities for the development of the shield machine industry, and at the same time, the demand for hydraulic cylinders for shield machines is increasing. The working conditions of large load and high side load put forward higher requirements for the reliability of shield machine hydraulic cylinder products. It prompts us to study new test technology and test equipment to meet market demand and product progress. [0003] The main thrust cylinder is used as the loading element and steering control mechanism of the shield machine cutterhead. When the shield machine moves in a straight line, multiple main thrust cylinders are required to load the cutterhead at the same time, and the loading force and stro...
