Abstract

The invention discloses an anti-caving supporting frame for underground work. The anti-caving supporting frame for the underground work comprises a bottom supporting plate and a top supporting plate.A high-pressure liquid supporting principle and a lever principle are used, the top supporting plate is enabled to be located in a trend of one side moving upwards, so that the side of the top supporting plate is more closer to the work surface, effective supporting strength is higher, boundedness is small, and safety performance is better; the anti-caving supporting frame for the underground workis provided with a spiral spring conflicting type maximum liquid strength control mechanism, and occurrence of a phenomenon of part damage caused by excessive pressure is prevented; in addition, theanti-caving supporting frame for the underground work is provided with a piston seal type liquid pressure drive mechanism, and directional drive is realized under the action of liquid; and the anti-caving supporting frame for the underground work is provided with a spherical size structure limiting type part connecting structure, two parts can be connected, and meanwhile, activity of the two partsin a connecting part cannot be affected.

Description

technical field [0001] The invention relates to the technical field of underground working equipment, in particular to an anti-caving supporting frame for underground working. Background technique [0002] At present, in underground workplaces, such as coal mining, supports are needed to prevent the top from falling, and the existing support methods are bidirectional upward supports. This support method has relatively large limitations and does not make effective use of mechanics. Contents of the invention [0003] The object of the present invention is to provide an anti-fall support frame for downhole work to solve the problems raised in the above background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an anti-fall support frame for underground work, including a bottom support plate and a top support plate, and one side of the upper surface of the bottom support plate is provided with an inte...
