Hydraulic steering system for transporting girder and transporting girder

Abstract

The invention provides a hydraulic steering system for a transporting girder and the transporting girder. The hydraulic steering system comprises a hydraulic steering machine, an oil storing tank, a front steering device and a rear steering device, wherein an input shaft of the hydraulic steering machine is connected with a steering wheel of the transporting girder, and an oil return opening of the hydraulic steering machine is connected with the oil storing tank; the front steering device and the rear steering device are centrosymmetric; and the hydraulic steering machine communicates with the front steering device and the rear steering device through an oil pipe, and the hydraulic steering machine drives the rotating direction of the front steering device to be opposite to that of the rear steering device. The rotating direction of the front steering device of the steering system is opposite to that of the rear steering device of the steering system, so that the steering radius is further reduced, and under extreme road conditions, a driver can conveniently change directions.

Description

technical field [0001] The invention belongs to the technical field of power-assisted steering of a beam transporting vehicle, and in particular relates to a hydraulic steering system of a beam transporting vehicle and a beam transporting vehicle. Background technique [0002] Integral beam transport vehicles are generally long, wide and have many wheels. Beam trucks often need to run on uneven roads, and such road conditions make each wheel of the beam truck unable to roll against the ground. In order to ensure the safety of the items on the beam transport vehicle, it is necessary for the wheels to be able to roll and walk on the surface. Furthermore, beam transport vehicles often need to turn on narrow roads. Existing beam transport vehicles use traditional front and rear steering devices for steering, although to a certain extent it solves the need for large turning radius caused by independent front wheel steering or rear wheel steering. However, there is still the pro...

Problems solved by technology

Furthermore, beam transport vehicles often need to turn on narrow roads. Existing beam transport vehicles use traditional front and rear steering devices for steering, although to a certain extent it solves the need for large turning radius caused by independent front wheel steering or rear wheel steering. However, there is still the problem that the turning radius is relatively large, and it is not easy or difficult to turn around in extreme road conditions.
