A Supporting Device for Anti-shock Tendency Roadway with Deformation Buffer

Abstract

The invention discloses an impact-resisting tendency roadway support device with deforming and buffering functions and relates to the field of mining equipment. Inner support plates with better elastic performance are arranged on the inner side of an outer support side plate and the inner side of an outer support top plate, in this way, when being impacted, the inner support plates can achieve buffering deformation, and thus the problem that due to rigid connection, a support is damaged is prevented. A buffering gap is formed in the connecting portion between the outer support side plate and the outer support top plate, the buffering gap can meet certain buffering deformation, the support performance is ensured, buffering mechanisms are contained and arranged in the buffering gap, impact force can be buffered and corrected, and the support ability is ensured. The buffering mechanisms achieve transverse and vertical buffering, buffering support efficiency in the different directions isachieved, meanwhile, the transverse buffering mechanism and the vertical buffering mechanism can carry out buffering in the different directions, fine adjustment control of a space angle is achieved,and the support effect is ensured.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to an anti-impact tendency roadway support device with deformation buffering. Background technique [0002] Traditional roadway support generally adopts the way of supporting the roof and supporting side plates with anchor rods and anchor cables for support. This kind of ordinary supporting roof and supporting side plates are rigidly and tightly fixed. When the impact occurs, local deformation is easy to occur, resulting in local stress concentration, which in turn aggravates the damage of the supporting steel plate, causing damage to the supporting steel plate, especially in some roadway support occasions that are prone to impact force. Once the steel plate is slightly deformed, the It is easy to make the place fragile and affect the safety and reliability of the roadway support. Once such a problem occurs, it is difficult to correct it, which greatly affects the roadway s...
