Embodiment Construction

[0024] The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

[0025] Such as Figure 1 to Figure 3 As shown, a large-scale mine truck suspension oil cylinder co-frame simulation test device,

[0026] The stand 1 includes a base plate 1-1 and two symmetrically arranged L-shaped side risers 1-2 welded and fixed on the base plate 1-1, and the lower side of the L-shaped side riser 1-2 is welded to the base plate 1-1 Fixed ribs I1-5. The front sides of the two L-shaped side risers 1-2 are welded and fixedly connected with a front riser 1-3, and the rear sides of the two L-shaped side risers 1-2 are welded and fixedly connected with a rear riser 1-4. There are a plurality of vertically arranged strip-shaped positioning grooves I1-31 arranged on the front side of the front vertical plate 1-3, and the strip-shaped positioning grooves I1-31 are arranged horizontally; Arrang...

Abstract

The invention discloses a suspension oil cylinder common-frame simulation test device for a large mining truck, and belongs to the technical field of hydraulic cylinders. A rack comprises a baseplate, an L-shaped side vertical plate, a front vertical plate and a back vertical plate; a rack connecting body is mounted on the front vertical plate; a loading base is fixed below the rack connecting body; a loading connecting body is mounted on the loading base; a tested oil cylinder is connected between the rack connecting body and the loading connecting body; and a loading device is fixed below the loading base. The tested oil cylinder is fixed on the rack through simulating a main machine mounting form; and a loading oil cylinder in the loading device performs dynamic loading test under the simulation working condition on the tested suspension oil cylinder to simulate the use working conditions of the suspension oil cylinder to the greatest extent to inspect related reliability of the suspension oil cylinder. The device is simple in structure and low in production cost, and simulates the use working conditions of products to the greatest extent through controllable loaded loads; and the rack is high in compatibility and suitable for most existing suspension oil cylinder product tests.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a co-frame simulation test device for suspension oil cylinders used for large mining trucks. Background technique [0002] Large mining trucks generally refer to a specialized vehicle used in the open air to complete tasks such as rock and earth transportation and ore transportation. It is mainly used in large-scale construction sites such as open-pit mines, port terminals, water conservancy and hydropower construction sites, and transportation infrastructure construction. With the development of the domestic economy, the rapid development of infrastructure construction and the continuous increase in the demand for mineral energy will definitely drive the rapid development of the large-scale mining truck industry. As a key component of large mining trucks, the reliability of the suspension cylinder has attracted more and more attention from main engine customers, esp...
