Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0025] An automatic frame-moving method for hydraulic supports aimed at broken bottom plates. By adding the function of "pause frame-moving, hold bottom up" during the frame-moving process, the frame-moving action is suspended multiple times during the frame-moving process, and the lifting motion is suspended during the frame-moving action. Bottom holding, so that the moving of the hydraulic support forms a step-up process, reducing the phenomenon of coal piles during the moving process.

[0026] See attached figure 1 , the present invention adopts the support controller to execute the automatic rack moving control operation program, and the specific steps are as follows:

[0027] The first step is the column lowering step: the support controller executes the column lowering step in the auto...

Abstract

The invention discloses an automatic hydraulic support advancing method for a breaking bottom plate. The automatic hydraulic support advancing method comprises the following steps: step 1, executing the action of descending a column; step 2, starting executing the actions of lifting the bottom and advancing a support at the same time after finishing the action of descending the column; pausing theaction of advancing the support for at least once in the process of the whole stroke of advancing the support, continuing to implement the action of lifting the bottom during the pausing of the action of advancing the support; and step 3, executing the action of lifting the column after finishing the actions of lifting the bottom and advancing the support. The automatic hydraulic support advancing method executes the actions of lifting the bottom and advancing the support at the same time, the support is advanced while the bottom is lifted, or that the action of lifting the bottom is executedall the time in the process of advancing the support, the support is advanced while the bottom is lifted, the lifting between lifting the bottom and advancing the support is strengthened, the whole hydraulic support forms the process of stepping up, the height of the hydraulic support gradually increases due to the method, a foot of the hydraulic support does not reach the bottom plate in the process of advancing the support, the method is suitable for the condition that the bottom plate on a working surface is soft, and the phenomenon of stacking the coal in the process of advancing the support is reduced.

Description

technical field [0001] The invention belongs to the field of hydraulic support control of a fully mechanized mining face, and relates to a hydraulic support control method, in particular to a hydraulic support automatic moving method for a broken floor. Background technique [0002] With the continuous progress of coal mining technology, my country's coal mines are developing towards digitalization and high automation. In the automation process of the fully mechanized mining face, the automatic follow-up of the hydraulic support is a very critical link. Only after the hydraulic support can realize the automatic follow-up function, the fully mechanized mining automation is a complete control system. very important. [0003] The automatic frame moving program control operation refers to the process that the frame controller of the hydraulic support controls the frame sequence according to the set parameters to complete the process of lowering the column, pulling the frame, an...
