Abstract

The invention discloses an adjustable supporting device for coal mine roadway supporting, comprising a base. A screw post is integrally formed above the base; a rotary adjusting sleeve is mounted outside the screw post in threaded manner; a fixing seat is arranged at the upper end of the rotary adjusting sleeve; a limiting rotary ring in rotational connection with the rotary adjusting sleeve is integrally formed at the lower end of the fixing seat. The adjustable supporting device designed herein allows supporting force for a roadway top to be adjusted conveniently through a jack and the rotary adjusting sleeve during supporting, and roadways of various heights can be supported conveniently and quickly in this way; further, the same support can be provided with multiple bases at any time for the purpose of supporting, and therefore, reinforcing the supporting performance of a local area is greatly facilitated; the adjustable supporting device also allows the supporting force for the roadway top to be adjusted conveniently through the jack and the rotary adjusting sleeve during support, so that collapse is avoided to great extent; the adjustable supporting device has high application value.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to an adjustable support device for coal mine roadway support. Background technique [0002] Coal mine is an important source of energy and an important industrial raw material in our country. Our country is rich in coal reserves, and coal mining is an important industry in our country. Since open-pit coal mines only account for a small part of coal mine resources, it is necessary to dig coal mines underground. When mining coal mines, a large number of roadways will be generated. These roadways are excavated due to the underlying supports. Lack of necessary support is prone to collapse events, so manual laying of support equipment is required for support. The traditional support equipment is mainly supported by wooden boards. Due to the limited compressive capacity of the wooden boards and the inconvenient adjustment of the support strength, landslides are still prone to o...
