Abstract

The invention discloses a simulation condition tester for a supporting leg type hydraulic cylinder, and belongs to the technical field of hydraulic cylinders. A column is fixed on a base plate; a crossbeam is hinged to the upper end of the column; the tested hydraulic cylinder is mounted in the middle portion of the crossbeam; one end of the tested hydraulic cylinder is connected with a first loading device, and the first loading device is connected onto the base plate; the end, far from the column, of the crossbeam is connected with a second loading device; and the second loading device is connected onto the base plate. The loading load and frequency of the first and second loading hydraulic cylinders are adjusted by a loading system, dynamic loading test for the tested hydraulic cylinderis realized in practical load spectrum, related conditions during work of the supporting leg type cylinder are simulated, and related performances including shaking sound, rebounding, offset load resistance, weld seam intensity and service life are tested. The tester is simple in principle and structure and low in design and manufacturing cost, can test the simulated condition by controllable loading before that the supporting leg hydraulic cylinder leaves factory, potential safety hazards are eradicated, and related cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to an outrigger hydraulic cylinder simulation operating condition test device. Background technique [0002] Outrigger hydraulic cylinders generally refer to four retractable hydraulic cylinders protruding from the chassis of the vehicle in order to ensure the stability of the fuselage during the operation of the engineering vehicle. They are connected vertically to the ground through ball strands, and support the main engine like four legs. Vehicles, hence the name outrigger hydraulic cylinders, are also called vertical hydraulic cylinders. [0003] Outrigger hydraulic cylinders are mainly used for construction machinery such as wheeled cranes, truck-mounted cranes, pump trucks, and rotary drilling rigs that require high stability of the fuselage. With the development of the domestic economy, the infrastructure construction is in the ascendant, which will definitely st...
