Abstract

The invention discloses an outrigger hydraulic cylinder simulation working condition test device, which belongs to the technical field of hydraulic cylinders. A column is fixed on the bottom plate; the upper end of the column is hinged with a beam; the tested hydraulic cylinder is installed in the middle of the beam; one end of the tested hydraulic cylinder is connected to the first loading device, and the first loading device is connected to the bottom plate; Two loading devices, the second loading device is connected to the base plate. Adjust the loading load and loading frequency of the first loading hydraulic cylinder and the second loading hydraulic cylinder through the loading system, realize the dynamic loading test under the measured load spectrum of the tested hydraulic cylinder, simulate the relevant working conditions when the outrigger cylinder is working, and test Its vibration, rebound, anti-eccentric load, weld strength, service life and other related properties. The principle and structure of the invention are simple, and the design and manufacture cost is relatively low. Through the controllable loading load, the simulated working condition test can be carried out before the outrigger hydraulic cylinder leaves the factory, which not only eliminates potential safety hazards but also greatly reduces related costs.

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...
