Abstract

The invention provides a jacking support device used at the tail end of a scaffold and a pressure monitoring method for solving the problems that in the prior art, mine cave interior support is difficult, and real-time monitoring of the pressure after support is not convenient. The jacking support device comprises a tail steel pipe, a screw sleeve is arranged in the tail steel pipe, a pressing block is arranged on the outer side of the top of the screw sleeve, and a lifting rod is arranged in the screw sleeve. A top disc is arranged on the top of the lifting rod. Jacking support devices are arranged at the two ends of the scaffold, the jacking support devices are adjusted by rotating the lifting rods through spanners, and therefore the jacking support devices can adapt to the height of the cave. A force meter is arranged in the jacking support device and located between the pressing block and a gasket, and after installation is finished, the force meter is not stressed. When the inner pressure of the cave suddenly changes due to accidents, the read pressure value displayed by the force meter changes accordingly, and an operation worker is reminded to pay attention to protection.

Description

technical field [0001] The invention relates to the field of mine safety production, in particular to a jacking support device and a pressure monitoring method for the end of a scaffold. Background technique [0002] Since the beginning of the 21st century, my country's economy has developed rapidly. Behind the rapid development is the high consumption of resources. At present, the section and depth of mineral resource mining are increasing. After excavation, the balance of the stress field of the surrounding rock of the cavern is destroyed. The redistribution of the stress field may cause large deformation of the surrounding rock, and even lead to accidents such as roof caving, slipping, and floor bulging. The situation is serious, especially in large-section caverns, where the risk factor of the surrounding rock is doubled, causing domestic Foreign scholars attach great importance to the support system. Scaffolding is a temporary frame set up by construction workers for the...
