Abstract
A gateway roof separation observation device consists of a deep base point anchor head, a shallow base point anchor head, a deep base point measuring rope, a shallow base point measuring rope, a screw, a main sleeve, a compression spring, a measuring rope tension bolt, a moving rule, an auxiliary sleeve, an extension spring, a roof separation indicator, a sleeve end cover and a zero adjusting bolt. The displacement difference between the rock stratum of the deep base point anchor head and the shallow base point anchor head and the surface of the gateway roof can be embodied by the process that the compression spring and the extension spring are compressed and stretched so that the moving rule and the roof separation indicator move in identical direction. The numerical value corresponding to the position of the roof separation indicator on the moving rule is right the separation amount between a deep stable rock stratum and an anchorage zone of the gateway roof. The device is not only simple in structure, convenient in use, safe and reliable, but also available for directly reading the roof separation amount and judging the roof separation situation without following data processing.
Description
Technical field
The utility model relates to a kind of roadway roof absciss layer observation device, is particularly useful for the observation of roadway roof absciss layer amount under the coal mine.
Background technology
At present, roof delamination observation device commonly used under the coal mine mostly is mechanical type roof delamination instrument, its ultimate principle is to observe dark basic point put the change in displacement on relative back surface with shallow foundation respectively, calculates the absciss layer amount of judging between dark basic point rock stratum and the anchorage zone by the later stage then.Use this class observation device, the roadway roof absciss layer amount can not directly be measured, and needs follow-up data processing; Also need to write down the data of all anchor point change in displacement during measurement, when useless, useless power, not directly perceived.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, a kind of roadway roof absciss layer observation device is provided, this device is not only simple in structure, esy to use, safe and reliable, and can directly read the roadway roof absciss layer amount, need not the follow-up data processing and can judge the roadway roof absciss layer situation.
For achieving the above object, roadway roof absciss layer observation device of the present utility model is made up of dark basic point anchor head, shallow foundation point anchor head, dark basic point lining rope, shallow foundation point lining rope, screw, master collet, compression spring, lining rope tightening screw, mobile chi, secondary sleeve, extension spring, top board separation layer indicator, sleeve end cap and the zeroing bolt surveyed; Master collet one end has internal thread, and secondary sleeve one end has external thread, and both sentence thread forms at connector and are connected; Dark basic point anchor head is connected with an end of dark basic point lining rope, is anchored at and stablizes in the rock stratum, and the lining rope other end is placed on the compression spring in the master collet, mobile bolt hole, the lining rope tightening screw cavity of surveying on the chi earlier, is fixed on the right-hand member of lining rope tightening screw; Shallow foundation point anchor head is connected with an end of shallow foundation point lining rope, be anchored in the rock stratum, anchorage zone, the lining rope other end is placed on the compression spring in the master collet, mobile shallow foundation point lining rope hole, top board separation layer indicator cavity, sleeve end cap, the zeroing bolt cavity of surveying on the chi earlier, is fixed on the right-hand member of zeroing bolt; Compression spring is in screw and moves and survey between the chi; Extension spring one end is fixed on the top board separation layer indicator, and the other end is fixed on socket end and covers.The lining rope tightening screw can guarantee not have relative displacement between dark basic point lining rope and the mobile survey chi, and can make compression spring be in pressured state by regulating the lining rope take-up device, thereby makes dark basic point lining rope tighten; Thereby the zeroing bolt can not only play and make extension spring be in tension state to make outside the effect that shallow foundation point lining rope tightens, can also make top board separation layer indicator move move left and right on the survey chi by back-out and screw-in, be marked with scale and move the survey chi, move a zero graduation of surveying on the chi thereby can allow a plate separation layer indicator aim at; When back generation absciss layer, the relative back surface distance of dark basic point anchor head increases, the dark basic point lining rope length that is in this tunnel item plate absciss layer observation device will reduce, and dark basic point lining rope will spur compression spring left, drives the mobile chi of surveying and is moved to the left; In like manner, rock stratum, shallow foundation point anchor head place is inner if absciss layer or plastic yield take place, and top board separation layer indicator also can be moved to the left; The position pairing reading of top board separation layer indicator on mobile survey chi is the absciss layer value between dark basic point anchor head stable rock stratum of living in and the rock stratum, shallow foundation point anchor head anchorage zone of living in.
Beneficial effect: the displacement on dark basic point anchor head and relative back surface, they rock stratum, place of shallow foundation point anchor head poor, can make by the compression and tension of compression spring and extension spring and move survey chi and move to equidirectional with top board separation layer indicator and embody, and the difference between the displacement on basic point anchor head and relative back surface, they rock stratum, place of shallow foundation point anchor head is the back deep and stablizes absciss layer amount between rock stratum and the rock stratum, anchorage zone deeply.The data of absciss layer amount directly can be read mobile the survey on the chi, do not need other calculating.
