Abstract
The utility model relates to measurement of mining heights of underground full-mechanized coal mining faces of coal mines, in particular to a mining height monitoring device for underground full-mechanized mining faces, which resolves problems that an existing mining height measuring method for coal mining faces is high in workload, incapable of directly displaying mining heights of the mining faces, and the like. The mining height monitoring device comprises a straight scale rod and a horizontal pointer, the straight scale rod is hung on a top beam of a hydraulic support and positioned at the center between two front posts of the hydraulic support, the horizontal pointer is fixed onto an outer cylinder of one of the front posts of the hydraulic support, and a free end of the horizontal pointer points to the straight scale rod which is provided with scale values gradually increased from the top of the straight scale rod to the bottom of the straight scale rod. The mining height monitoring device is simple in structure and brings convenience for use and observation, and a new 'shortcut' is created for mining height monitoring of the full-mechanized mining faces.
Description
Technical field
The utility model relates to the measurement of comprehensive mechanical coal mining workplace mining height under the coal mine, specifically is that the comprehensive mechanical coal mining working surface hydraulic support is used, realizes the down-hole fully-mechanized mining working mining height monitoring device that the coal-face mining height is measured under a kind of and the coal mine.
Background technology
According to " safety regulations in coal mine " requirement, must the strict mining height of controlling coal-face when adopting comprehensive mechanical coal mining under the coal mine.And at present the mining height of coal-face is mainly artificial dependence steel tape and measures, and workload is big, can't the real-time judge coal-face everywhere mining height whether meet the rules requirement, and then be difficult to control the mining height of coal-face, can't ensure that engineering safety carries out.
Summary of the invention
The utility model for solve existing coal-face mining height measuring method workload big, can not intuitively show problem such as workplace mining height, a kind of down-hole fully-mechanized mining working mining height monitoring device is provided.
The utility model is to adopt following technical scheme to realize: down-hole fully-mechanized mining working mining height monitoring device, comprise being hung on the hydraulic support back timber and placing the ruler bar of hydraulic support two front pillar central authorities and be fixed in the wherein horizontal pointer on the front pillar outer shell of hydraulic support that the free end of horizontal pointer vertically points to the ruler bar; The ruler bar is provided with the scale value that is progressively increased to the bottom by ruler masthead portion, and vertical range that the bottom scale value of ruler bar is a ruler masthead end to the vertical range of hydraulic support back timber supporting surface, horizontal pointer to the hydraulic support bottom surface and ruler bar bar long and value, the vertical range that the top scale value of ruler bar is a ruler masthead end to the vertical range of hydraulic support back timber supporting surface and horizontal pointer to the hydraulic support bottom surface and value.
For convenience the monitoring personnel determine the scale value that indicated by horizontal pointer on the ruler bar also to be coated with red, the white dichromatism reflective tape that is provided with at interval on the ruler bar fast, and red reflective tape equates with the width of white reflection band, are the integral multiple of unit scale.Like this, the monitoring personnel according on the ruler bar between horizontal pointer indicating bit and ruler masthead end or bottom the number of reflective tape just can determine the scale value of horizontal pointer indication fast.
During application, can calibrate this monitoring device to the vertical range of hydraulic support bottom surface to the vertical range and the horizontal pointer of hydraulic support back timber supporting surface by adjusting ruler masthead end.Variation in altitude along with hydraulic support, the ruler bar of monitoring device moves up and down, the scale value of horizontal pointer indicating bit correspondence is the mining height of hydraulic support present position on the ruler bar, therefore only need read the scale value of horizontal pointer indicating bit correspondence on the ruler bar, just can know also whether the mining height of this position meets the rules requirement.Coal mining unit driver and try to stop people from fighting each other the worker by checking monitoring device can obtain the workplace mining height simple and direct, in time, exactly, and then be controlled.When the utility model was provided with in workplace, several the hydraulic supports in every interval were provided with one and get final product.
The utility model is simple in structure, easy to use, be convenient to observe, and opened up new " shortcut " for the monitoring of fully-mechanized mining working mining height.
Description of drawings
Fig. 1 is a user mode synoptic diagram of the present utility model;
Among the figure: 1-hydraulic support back timber; The 2-front pillar; 3-ruler bar; The horizontal pointer of 4-.
Embodiment
As shown in Figure 1, down-hole fully-mechanized mining working mining height monitoring device, comprise being hung on the hydraulic support back timber 1 and placing the ruler bar 3 of hydraulic support two front pillars 2 central authorities and be fixed in the wherein horizontal pointer 4 on a front pillar 2 outer shells of hydraulic support that the free end of horizontal pointer 4 vertically points to ruler bar 3; Ruler bar 3 is provided with the scale value that is progressively increased to the bottom by ruler bar 3 tops, and vertical range that the bottom scale value of ruler bar 3 is ruler bar 3 tops to the vertical range of hydraulic support back timber 1 supporting surface, horizontal pointer 4 to the hydraulic support bottom surface and ruler bar 3 bars long and value, the top scale value of ruler bar 3 vertical range that to be ruler bar 3 tops arrive the hydraulic support bottom surface to the vertical range and the horizontal pointer 4 of hydraulic support back timber 1 supporting surface and value.
