This paper brings forth a kind of automatic pressurizing device which can resolve the problem of poor hydraulic support setting load directly without modifying the original hydraulic system excessively. On the basis of the control loop that is designed according to working requirements and conditions to realize automatic pressurization of stand column system, it is divided into pressurizing structure and auxiliary structure. Reserved liquid opening and unit design are used to design the automatic pressurizing device from the principle perspective, and it is also made associated with all units reasonably by improving the details. The automatic pressurizing device combines machinery and hydraulic pressure so that all structural units can finish the expected action and coordinate mutually under the effect of emulsion in order to finally realize the overall function of automatic and fast pressurization. On the basis of the simulated analysis of AMESim hydraulic simulation platform on the control loop and lifting support system loop of support stand column, the working performance of automatic pressurizing device and dynamic characteristics of control loop are simulated. The result after comparing and analyzing the simulation curve and site installation test of underground ZY12000/28/63D support finally shows that the device is able to enhance the setting load to above 30 MPa, which is basically the same with simulation result. It demonstrates that the design of automatic pressurizing device conforms to the expected pressurization requirements and the pressurization effect is significant.

液压支架初始力自动加压装置的设计

本文提出了一种自动加压装置，可以直接解决液压支架设定载荷差的问题，而无需对原有液压系统进行过多的改动。根据根据工作要求和工况设计的控制回路，实现立柱系统的自动加压，分为加压结构和辅助结构。从原理上讲，使用预留的液体开孔和单元设计来设计自动加压装置，并通过改进细节使其合理地与所有单元关联。自动加压装置将机械压力和液压压力结合在一起，使所有结构单元都能在乳化剂的作用下完成预期的作用并相互配合，从而最终实现自动快速加压的整体功能。在对AMESim液压仿真平台对立柱控制环和举升支撑系统环进行仿真分析的基础上，模拟了自动增压装置的工作性能和控制环的动态特性。对地下ZY12000 / 28 / 63D支架的仿真曲线和现场安装试验进行比较分析后的结果最终表明，该装置能够将设定载荷提高到30 MPa以上，与仿真结果基本相同。
