液压支架作为综采工作面三机中最重要的设备,其架型结构一旦确定下来之后,影响液压支架使用性能的则是其内部参数。内部参数的确定是液压支架总体设计的主要工作,在液压支架设计中称之为调参数,调参数应当依据一定的原则进行。结合示例的方法对这种调参数的设计原则进行具体阐述,即要求支架双纽线比较合理以及支架连杆受力尽量小,这样才能保证支架在井下工作面自身比较安全,同时又能很好地维护工作面的顶板以及煤壁的片帮问题。
As the most important equipment of three machines in fully mechanized coal mining face, hydraulic support is the internal parameter that affects the performance of hydraulic support once its frame structure is confirmed. The determination of internal parameters is the main work of the overall design of the hydraulic support, called the tuning parameters in the hydraulic support design, the parameters should be based on certain principles. The design principle of this parameter is described in detail by means of examples. That is to say, the double hinge line of the bracket is required to be reasonable and the force of the bracket connecting rod is as small as possible, so as to ensure that the bracket itself is safer in the underground working face and at the same time is very good To maintain the work of the roof and the coal wall to help solve the problem.
