Embodiment Construction

[0035] The invention proposes a wheel frame suspension hydraulic system of a container straddle carrier. The suspension hydraulic system is installed on the wheel frame. The suspension hydraulic system includes: a suspension oil cylinder, a light-load pipeline, a heavy-load pipeline and an intelligent pipeline. The container straddle carrier is light-loaded, and the hydraulic oil is supplied from the oil inlet to the suspension cylinder through the light-load pipeline, and the pressure of the suspension cylinder is light-load pressure. The container straddle carrier is heavy-duty, and the hydraulic oil is supplied from the oil inlet to the suspension cylinder through the heavy-duty pipeline, and the pressure of the suspension cylinder is heavy-duty pressure. The intelligent pipeline includes a pressure sensor, and the hydraulic oil is supplied from the oil inlet to the suspension cylinder through the intelligent pipeline, and the pressure of the suspension cylinder is adjusted ...

Abstract

The invention discloses a wheel frame suspension hydraulic system of a container straddle carrier. The suspension hydraulic system is installed on a wheel frame and comprises a suspension oil cylinder, a light-load pipeline, a heavy-load pipeline and an intelligent pipeline. When the container straddle carrier is light in load, hydraulic oil is supplied to the suspension oil cylinder from an oil inlet through the light-load pipeline, and the pressure of the suspension oil cylinder is light-load pressure; when the container straddle carrier is heavy in load, the hydraulic oil is supplied to the suspension oil cylinder from the oil inlet through the heavy-load pipeline, and the pressure of the suspension oil cylinder is heavy-load pressure. The intelligent pipeline comprises a pressure sensor, the hydraulic oil is supplied to the suspension oil cylinder from the oil inlet through the intelligent pipeline, and the pressure of the suspension oil cylinder is adjusted according to the pressure detected by the pressure sensor. The invention further discloses a control method of the wheel frame suspension hydraulic system of the container straddle carrier.

Description

technical field [0001] The invention relates to the field of transportation equipment, more specifically, to the wheel frame suspension technology of a container straddle carrier. Background technique [0002] Container straddle carrier is the main equipment for container transportation in container port terminals. Existing container straddle carriers are generally not equipped with a wheel frame suspension system. The main reason is that the container straddle carrier has too much weight, and ordinary mechanical suspension systems cannot carry such a large load. [0003] At present, some hydraulic suspension systems suitable for large-scale engineering vehicles and with relatively large load capacity have gradually appeared. For example, in the prior art, a hydraulic suspension device suitable for a vehicle with a large stroke is proposed, which includes a suspension unit connected to the vehicle frame and an axle connected to the suspension unit. The suspension unit incl...
