Embodiment 1

[0065] This embodiment provides a kind of anti-overturning stabilization method that is used for log grab car, please refer to figure 1 , the method includes;

[0066] Step 1: collecting a first signal, and obtaining a second signal according to the characteristics of the first signal.

[0067] Specifically, as Figure 5As shown, the signal acquisition module is mainly used to acquire the signals needed to establish the mathematical model of anti-overturning and stability. First collect the original signal of the relevant sensor or switch, and then calculate the real value of the required signal according to the characteristics of the signal. According to the requirements of the mathematical model establishment, the following signals need to be collected in total: the stroke sensor signal of the telescopic cylinder of the manipulator, which mainly feeds back the stroke distance of the telescopic cylinder of the manipulator; the stroke sensor signal of the boom pitch cylinder...

Embodiment 2

[0109] This embodiment also provides an anti-overturning stabilization system for a log snatch vehicle, including: a signal acquisition module, the signal acquisition module acquires a first signal, and obtains a second signal according to the characteristics of the first signal; A calculation module, the calculation module receives the second signal sent by the signal acquisition module, and calculates and outputs the overturning moment of the vehicle according to the second signal, wherein the overturning moment includes the value of the longitudinal overturning moment and Lateral overturning moment value; a stability control module, the stability control module receives the longitudinal overturning moment value and the lateral overturning moment value sent by the calculation module, wherein the calculation module and the signal acquisition module, stability Control Module Communication Connections

Abstract

The invention discloses a stabilizing method and a stabilizing system capable of preventing overturn of a log grabbing and lifting truck, and relates to the technical field of integral truck stabilization. The stabilizing method includes: acquiring a first signal, acquiring a second signal according to characters of the first signal; according to the acquired second signal, computing and outputting overturning moments of an integral truck; comparing a longitudinal overturning moment value with a first preset anti-overturning moment value to obtain a first comparison result, and / or comparing atransverse overturning moment value with a second preset anti-overturning moment value to obtain a second comparison result; judging whether the first comparison result satisfies a first preset threshold value or not, and / or judging whether the second comparison result satisfies a second preset threshold value or not; when the first comparison result cannot satisfy the first preset threshold value, and / or the second comparison result cannot satisfy the second preset threshold value, sending an alarm signal by an integral truck controlling system. The stabilizing method and the stabilizing system have the advantages that the truck is prevented from overturning when a mechanical arm is working, and a technical effect on ensuring stability of the truck is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle stabilization, and in particular relates to an anti-overturning stabilization method and system for a log snatch vehicle. Background technique [0002] At present, the transportation and installation of round logs in coal mines is mainly realized by manpower. This operation method has the problems of high safety hazards, high labor intensity and low work efficiency. Therefore, it is urgent to develop a special vehicle for snatching, handling, and installation of logs. The log snatch truck is a special special equipment specially developed to meet the needs of underground coal mines. [0003] The log snatch truck is mainly used for snatching and short-distance transportation of large logs in coal mines. During the working process of the vehicle, due to the large telescopic stroke of the mechanical arm and the 360° rotation of the platform, the mass center of gravity of the vehicle will sh...
