Abstract

The invention relates to a hydraulic support of a suspension roof timber capable of adjusting the direction, which is used for supporting an underground mining working face of a coal mine. A front telescopic block, a rear telescopic block and a push oil cylinder, which can enable a main beam and an auxiliary beam to realize horizontal and vertical dislocation are arranged between the main beam and the auxiliary beam, and the extension and the contraction of the front telescopic block and the rear telescopic block are controlled by a direction-adjusting oil cylinder, thereby realizing the function of transversely adjusting the support. The main beam, the auxiliary beam, the front telescopic block, the rear telescopic block, the push oil cylinder and upright posts constitute the hydraulic support of the suspension roof timber capable of adjusting the direction, which can be used independently, and a plurality of the hydraulic supports of the suspension roof timber capable of adjusting the direction can be further connected into a whole through front blocking blocks and rear blocking blocks to constitute a combined support of the suspension roof timber capable of adjusting the direction. The support has simple structure, convenience in combination, light weight, high strength, easiness in direction adjustment and strong stability, and can be used for mechanized mining, blasting mining and roof coal caving mining working faces.
