Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic supports, in particular to a height-adjustable control valve frame of a hydraulic support. Background Art

[0002] The hydraulic support is a structure used to control the mine pressure at the coal mining face. The mine pressure at the mining face acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of each support of the hydraulic support and the combined force of the external load acting on the hydraulic support by the roof are exactly in the same straight line, then the hydraulic support is very suitable for the surrounding rock of the mining face. Therefore, when using the hydraulic support, its height needs to be adjusted to facilitate the support of mines at different heights.

[0003] In Chinese utility model patents: For example, CN207609433U discloses an adjustable height control valve frame for a hydraulic support, comprising a top beam, a control valve group and at least two sections of regulating valve plates; the top regulating valve plate is connected to the top beam, and the bottom regulating valve plate is connected to the control valve group; the regulating valve plate is provided with a plurality of adjustment holes along its length, and adjacent regulating valve plates are fixed with bolts and nuts. The height of the control valve group can be adjusted by adjusting the relative positions of adjacent regulating valve plates. According to the height variation amplitude, the length of each valve plate section can be increased when the amplitude is large, and the number of regulating valve plate sections can also be increased. The utility model provides a control valve frame capable of adjusting the height of the control valve on a hydraulic support. The control valve frame can adjust the height of the control valve according to the support height of the hydraulic support during operation, which is convenient for operation, and also avoids misoperation of the control valve, providing a guarantee for safe production.
