Description

Guide rod type double-wheel milling mixer bracket device control system

Technical Field

The most important operation step of the guide rod type double-wheel milling mixer in the construction process is the mutual matching of the lifting rod and the dropping rod. In the existing milling and stirring machine, the upper bracket and the lower bracket are still operated to the position of the clamping groove in a form of manual visual observation, and the control of rod falling and rod lifting is realized through the matching action of the clamping oil cylinder. The operation of the mode has excessive human factors, and if the clamping position is improper or the clamping is not firm, in the switching process of the upper bracket and the lower bracket, the weight of the mast is too heavy to cause the slide rod, so that construction accidents are caused.

In addition, the upper bracket of the guide rod type double-wheel milling mixer is suspended by a steel wire rope, and the lower bracket is suspended by an oil cylinder. When the rod is dropped and lifted, the clamping oil cylinders are interlocked. Under the condition that the clamping of the upper bracket is switched to the clamping of the lower bracket, if the stress of the steel wire rope is large, at the moment that the oil cylinder of the upper bracket is loosened, the tensile force of the steel wire rope acts on the upper bracket, the upper bracket can be caused to move upwards quickly, and the mast shakes. And under the condition that the clamping of the lower bracket is switched to the clamping of the upper bracket, if the stress of the steel wire rope is small, the phenomenon of a sliding rod can be caused at the moment that the oil cylinder of the lower bracket is loosened. If an emergency occurs, the upper bracket and the lower bracket need to be simultaneously tightened and the working condition of pulling out the mast in a resultant force manner, if the tension of the steel wire rope is not strictly controlled, the condition that the oil cylinder of the lower bracket moves along with the upper bracket and the mast occurs, the balance valve is damaged, and the oil cylinder deforms.

Finally, because the upper carriage is suspended by a wireline, some limitation on its range of travel is required, which could otherwise cause damage to the equipment.
