Mine roadway roof separation monitoring device with high dustproof capability

Abstract

The invention discloses a mine roadway roof separation monitoring device with high dustproof capability. The mine roadway roof separation monitoring device comprises a support frame, wherein installation grooves are respectively formed in the two sides of the support frame; installation frames are arranged at the two ends of the installation grooves; the two adjacent installation frames are connected through bolts; lead screws are uniformly welded in the middle of a support plate; a nut is arranged in the middle of each corresponding lead screw through threads; a power connection box is arranged in the middle of the top surface of an installation plate; a mercury box is fixedly arranged on the top surface of a support strip; one end of a connecting wire is arranged inside the power connection box; an indicating lamp is arranged at one side of the top end of the support frame; and one end of the indicating lamp is connected with the power connection box through the connecting wire. Theinstallation plate is installed on the screw rods and is enabled to be fixedly arranged between the two nuts so as to be fixed; and when mine roadway separation occurs and the generated pressure is too high, mercury in the mercury box falls into the power connection box to connect the two connecting wires, and at the moment, the indicating lamp is turned on, so that workers are able to react quickly and escape, and the safety coefficient of the workers in construction is improved.

Description

technical field [0001] The invention belongs to the technical field of detachment monitoring devices, and in particular relates to a detachment monitoring device for the roof of a mine roadway with strong dust-proof capability. Background technique [0002] During the construction process of the shaft, it is necessary to monitor the stress state of the surrounding rock of the shaft. The invention indirectly monitors the separation of the roof through the deformation of the roof of the shaft, thereby ensuring the safety of the workers. [0003] When monitoring the separation layer of the mine roadway, the conventional monitoring method is that the construction personnel observe through experience and knock on the roof, so that the possible roof caving cannot be found in time, which threatens the personal safety of the staff and causes low work efficiency. Thereby bring hidden danger to safe production. Contents of the invention [0004] The present invention provides a min...
