Problems solved by technology

[0004] The airborne temporary support device of the roadheader, due to its complex structure and interference with the work of the roadheader, needs to be modified for the structure of the roadheader before it can be used
In addition, because the roadheader generally can only excavate the roadway with an inclination angle below 18°, this kind of temporary support device is not suitable for tunneling in a roadway with a large inclination angle.

Abstract

The invention discloses a suspension type driftage temporary supporting device and a use method thereof. The device comprises an I-shaped steel suspending beam, a supporting platform, a lifting platform, a moving frame and a plurality of hydraulic cylinders. The components are used for realizing the quick and continuous driftage, reducing the sinking and layering of a top tray, reducing the accidents of head-on roof caving and deviation, and reducing the labor intensity.

Description

technical field [0001] The invention relates to a temporary support device for roadway excavation in coal mines. Background technique [0002] At present, there are mainly two types of temporary support for roadway excavation at home and abroad, that is, temporary support of "wearing caps and pillars" and temporary support of sheds. These two temporary support forms have slow support speed, small support area, cumbersome operation, long empty roof time, large empty roof area, prone to settlement and caving of the roof, high labor intensity for workers, poor safety performance, and frequent roof fall Injury accident. [0003] The roadway advanced temporary support hydraulic support is a kind of temporary support equipment for roadway excavation that has appeared in recent years. Due to some technical problems that have not been solved, it is in the trial stage and has not been popularized. [0004] The airborne temporary support device of the roadheader has a complex struct...
