| الوصف: | Abstract 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. |
