Embodiment 1

[0038] Such as figure 1 As shown, in this embodiment, a roof delamination instrument is provided, including an anchor fluke 16, a push rod (not shown in the figure), a box body 1 and a steel strand 17 arranged inside the box body 1 Damper 11, guide pulley 12, elastic tensioning device 13, steering device 14, friction wheel 15 and grating sensor 4.

[0039] The steel strand 17 drawn from the outlet of the damper 11 bypasses the guide pulley 12, passes through the elastic tensioning device 13 and then bypasses the steering device 14, and is fixed on the anchor fluke 16 by the push rod after winding the friction wheel 15 for one week; , the damper 11 is fixedly arranged on the inner wall below the box body 1; the guide pulley 12 is a fixed pulley, and the outlet of the steel strand 17 corresponding to the damper 11 is arranged above it, so that the bypassed steel strand 17 does not contact with the damper The contact at the opening of the damper 11 optimally makes the steel stra...

Embodiment 2

[0051] This embodiment is a detector for two fluke separation layers. On the basis of the first embodiment, two sets of fluke transmission mechanisms are simultaneously arranged inside the same box and share the same adjustment device.

[0052] Such as Image 6 As shown, the steel strand 20 and the steel strand 21 are set in the box body 2 at the same time as the same transmission device as in the first embodiment, and the cylinder 19 with a smooth surface is used as an adjustment device to adjust the steel strand on the friction wheel. angle of wrapping.

Abstract

An embodiment of the invention discloses a roof separation indicator and belongs to the technical field of separation detection. Steel strands can be kept located at an elastic tension device. Therefore, failure of a friction wheel caused by loosening of the steel strands is avoided effectively. Positive and reverse rotation data of the friction wheel can be accurately measured by a grating sensor, and separation can be detected accurately.

Description

technical field [0001] The invention relates to a layer separation detection device, in particular to a roof separation device. Background technique [0002] The detection of mine roof and surrounding rock is an important item for mine disaster prediction. Mine roof fall and surrounding rock collapse is one of the most serious disasters in various mines, which seriously threatens the production safety of mines and will cause huge economic losses and casualties when it occurs. In recent years, due to the continuous extension of the excavation surface and the expansion of the mining area, mine production has developed in depth, the threat of roof fall and landslide has become increasingly serious, and the prevention and control tasks have become more and more difficult. Mine roof disasters seriously threaten the life safety of mine workers. [0003] At present, the roof separation instrument is generally used to detect the change of the separation layer of the roof rock layer,...
