Description

TECHNICAL FIELD

[0001] The utility model relates to coal mine roadway roof separation monitoring technical field especially relates to a lock dead subassembly for roof separation device and roof separation device. BACKGROUND

[0002] With mine gradually towards deep mining, the pressure of coal mine roadway roof gradually increases, and is easy to produce separation, and the separation is the difference between the layer and the layer due to the different step sinking between the different roof strata, and the separation can reduce the stability of the roadway roof, and even leads to the roadway collapse in serious case, therefore, the monitoring demand of the roof separation is increasingly severe.

[0003] In the prior art, generally, the installation hole is drilled in the roadway roof, and the roof separation instrument is installed in the hole to detect the separation condition of the roof, the roof separation instrument is generally composed of a body and an anchor head piece, and the both are connected through a steel wire rope, and the commonly used roof separation instrument is roughly divided into two kinds:

[0004] One is mechanical, which judges the displacement of the steel wire rope through different scales on the scale ruler to judge the separation degree;

[0005] One is electronic, which uses a sensor to connect with the steel wire rope, and judges the displacement of the steel wire rope through the reading on the sensor to judge the separation degree.

[0006] Among them, the mechanical roof separation instrument has the advantages of low cost and low failure rate, and the disadvantage is low measurement accuracy; and the electronic roof separation instrument has the advantage of high measurement accuracy, but the corresponding cost is high.

[0007] Whether the mechanical roof separation instrument or the electronic roof separation instrument, the anchor head piece is the same, the ordinary anchor head piece includes a body and an anchor claw, and when placed, the rod and other tools are used to top into the installation hole and fixed by the grabbing force of the anchor claw and the hole wall, and since the strata of the roof are often not homogeneous, and there may be multiple strata, therefore, the hole wall of the installation hole is not smooth, and the hole diameter is uneven, and the bending degree of the hole is too high, and the ordinary anchor claw has the following disadvantages:

[0008] Firstly, since the structure of the anchor claw is single, it cannot adapt to different shapes of the hole wall, and there may be problems of unstable fixation and even falling off, which may cause errors in the measurement results and even danger;

[0009] Secondly, when the anchor claw is buried in the hole, an external tool such as a steel pipe is generally used to top into the hole, and since the anchor claw is not connected with the steel pipe, when topped, the hole may be too large in curvature or the hole wall is too rough, which causes the topping process to be not smooth, and affects the installation efficiency.
