Portable roof separation instrument for ore-rock exploitation

Abstract

The present invention discloses a portable roof separation instrument for ore-rock exploitation. The instrument comprises a housing, two ends of the housing are fixedly connected with vernier scales,two sides of the front surface of the housing are embedded with fixed bolts, the top end of a connection tube is connected with a fixed tube, the top end of the fixed tube is fixedly connected with afixed anchor head, the external portion of the fixed tube is sleeved with a water swelling rubber gasket, a spring is connected with the inner side of the fixed anchor head of the external portion ofthe fixed tube, one ends of the vernier scales are embedded with steel wire ropes, the top ends of the steel wire ropes are provided with anchoring devices, and one sides, close to the anchoring device, at the external portions of the steel wire ropes are provided with cat-pad buckles. The portable roof separation instrument is provided with the cat-pad buckles to conveniently dismount and receivethe roof separation instrument, is provided with the spring to allow the fixed tube to be firmly anchored in the drilling hole of a wall rock and is provided with the water swelling rubber gasket toprevent the fixed tube from generation of displacement in the working process.

Description

technical field [0001] The invention relates to the technical field of ore and rock mining, in particular to a portable roof separation instrument for ore and rock mining. Background technique [0002] The Roof Detachment Instrument is a special monitoring instrument for monitoring the movement of the roof strata. It can respectively display the detachment of the roof strata within the length range of the bolt and outside the same range of the bolt, and provide confirmation for underground mine engineering technicians and testing personnel. The length and tensile strength of the bolt, and the scientific basis needed to understand the rationality and economy of the bolt used, so as to effectively prevent the occurrence of roof collapse accidents and ensure the safe production of underground mines.

Problems solved by technology

[0003] A Chinese patent discloses a new type of roof delamination instrument (authorized announcement number CN204043605U). This patented technology can solve the problem of circuit failure caused by water vapor condensation, which leads to the failure of the roof delamination instrument. However, there is no cat claw buckle, which is inconvenient to disassemble. There is no spring for storing the roof abscission instrument. During installation, the fixed pipe cannot be firmly anchored in the drilling hole of the surrounding rock. There is no water-expandable rubber ring, and the displacement of the fixed pipe cannot be prevented during the work process.
