Adjustable type hydraulic support structure

Abstract

The invention discloses an adjustable type hydraulic support structure. The adjustable type hydraulic support structure comprises a base, universal wheels and support legs, the top of vertical supportrods is provided with a horizontal support faceplate, the inside of each vertical support rod is provided with a cavity with the top open, the side surface of each vertical support rod is fixedly provided with a vertical sliding groove communicated with the cavity, and inside each cavity is provided with a lifting column; the sides of the horizontal support faceplate are connected to the top endsof the lifting columns through rib rods; lifting air cylinders are fixed between the bottom ends of the lifting columns and the bottom walls of the cavities; the side surfaces of the horizontal support faceplate are fixedly provided with locking chains for connecting the side walls of hydraulic units; the side surface of the horizontal support faceplate is also fixedly provided with a driving motor, the spindle of the driving motor is fixedly provided with an eccentric wheel, and the surface of the eccentric wheel is provided with a U-shaped ring groove. The adjustable type hydraulic supportstructure is reasonable in structure, convenient to operate, capable of ensuring position precision, less prone to displacement or inclination, beneficial to ensuring use stability and reliability, and high in applicability and practicality.

Description

technical field [0001] The invention belongs to the technical field of support structures, and in particular relates to an adjustable hydraulic support structure. Background technique [0002] Most fully mechanized mining equipment in coal mines use hydraulic supports, which generally have a large volume. The traditional hydraulic supports are mainly composed of a base, a support and a slide block arranged on the support. When in use, the hydraulic structure is fixed on the On the slider, and the bottom end of the slider is connected to the base through the lifting cylinder. Although it can realize the support operation, its stability in use is relatively limited, and it is prone to loosening or falling off, and its applicability and practicability are limited. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable hydraulic support structure with reasonable structure and strong applicability. [0004] The technical solution to...
