Clamping vehicle clamp beam equal load protection method, device and clamping vehicle

Abstract

The invention provides a schnabel car pincerlike beam uniform load protection method, a schnabel car pincerlike beam uniform load protection device and a schnabel car. The schnabel car pincerlike beam uniform load protection method comprises that a first pressure sensor timely collects first real-time pressure information of a first compression leg cylinder rodless cavity, and a second pressure sensor timely collects second real-time pressure information of a second compression leg cylinder rodless cavity; and a control module judges whether unbalance load exists or not according to a difference value of the first real-time pressure information and the second real-time pressure information, a solenoid valve is controlled to close a target oil way if the unbalance load exists, and the target oil way is one of the two oil ways which are respectively communicated with the first compression leg cylinder rodless cavity and the second compression leg cylinder rodless cavity and provided with big pressure. By means of the scheme, whether unbalance load exists or not is obtained by judging the pressure difference of the rodless cavities, the solenoid valve is used for closing the oil way which is connected the compression leg cylinder rodless cavities and provided with big pressure, the other compression leg cylinder is continuously extended out, accordingly uniform load purposes are achieved, the unbalance load problem can be solved, and buckling deformation of a pincerlike beam can be avoided.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a clamping car clamp beam equal load protection method and device and a clamping car. Background technique [0002] The tonnage car is one of the largest tonnage vehicles in rail freight cars at present, and it plays a huge role in the transportation of large goods. For example, it can carry the frame of a large press in a forging plant, and a large generator stator in a power plant. [0003] Such as figure 1 , figure 2 As shown, when the clamping vehicle is in use, two clamping vehicles need to be parked oppositely on the track, and cargo 23 is placed between the two clamping vehicles, and the placed cargo 23 connects the two clamping vehicles together to form a trucks. In order to load and unload goods conveniently and reduce the loading and unloading time, the clamping vehicle realizes the lifting of the goods through the horizontal expansion and contraction of the p...
