Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] figure 2 is a schematic diagram of a control method for the suspension of a rough-terrain tire crane according to an embodiment of the present invention, such as figure 2 As shown, the method can be executed by the controller of the off-road tire crane, and mainly includes the following steps:

[0031] Step S21: Read the working condition of the rough terrain crane.

[0032] The working condition of the rough terrain crane is set by the driver after the rough terrain crane is started, and the moment limiter of the rough terrain crane usually saves the information of the working condition after setting. The moment limiter is a device that prevents the lifting moment or lifting capaci...

Abstract

The invention provides a method, a device and a system for controlling suspension of an off-road tire hoister, and aims to solve the problem that the suspension switching mode of the off-road tire hoister is poor in safety in the prior art. The method comprises the following steps of: reading information of a working condition of the off-road tire hoister; if the working condition is a tire-hoisting working condition or a carrying working condition, setting a rear axle suspension state of the off-road tire hoister as a rigid state; and if the working condition is not the tire-hoisting working condition and the carrying working condition, determining and setting the rear axle suspension state of the off-road tire hoister according to a rotary angle of an upper trolley of the off-road tire hoister. By the adoption of the technical scheme, the working safety of the off-road tire hoister is enhanced.

Description

technical field [0001] The invention relates to a control method, a control device and a control system for the suspension of an off-road tire crane. Background technique [0002] Rough terrain cranes generally use the rigid connection of the front axle, and the rigid and flexible connection of the rear axle. The flexible state can give full play to the superiority of the rough terrain crane, and the rigidity can ensure the safety of the rough terrain crane under special working conditions. figure 1 It is a schematic diagram of some parts of the rough terrain crane according to the prior art, in figure 1 Shown in the figure are solenoid valve 11, suspension oil cylinder 12, vehicle frame 13, tire 14, suspension 15 and drive axle 16. [0003] At present, the switching method of the suspension of the rough terrain crane is that the driver judges whether the suspension of the rough terrain crane needs to be in a rigid state or a flexible state according to the actual situatio...
