Abstract
The utility model discloses a meter for measuring displacement of head plate or under plate, comprising a vertical measuring system, a horizontal measuring system, and a deviation direction measuring system. The utility model has the functions of measuring the parameters of the vertical displacement, the horizontal displacement, and the direction of the deviation angle. The utility model is in particular suitable for observing and measuring the mine pressure with a large inclination angle and steep working face.
Description
The utility model a kind of measuring instrument that is used to measure the displacement of workplace roof and floor of touching upon, it belongs to rock pressure [in mine observing apparatus technical field.
In recent years, mining engineering circle in China, the ore deposit presses observing apparatus that significant progress has been arranged, develop into precision by simple measuring staff and bring up to 1% millimeter dynamic instrument, develop into location by simple survey displacement and move speed, and critical value can be set, the acousto-optic that transfinites is reported to the police automatically, novel instrument such as remote-control romote-sensing.All these can only measure a kind of parameter of total displacement without any exception, and great majority are to press observation for the ore deposit of level and gently inclined seam workplace to design, notice concentrates on measuring accuracy mostly and improves test automation degree aspect, thereby ignored the displacement that roof and floor and two is helped, no matter be at workplace or in the displacement in tunnel, come down to the vector motion of a complexity, especially along with the increase of seam inclination, total displacement is not only in the roof and floor relative motion, also has the displacement of angular range, according to existing Structural Observed data Analysis, its direction vector also is a very complicated problems.
Weak point at above technology, task of the present utility model is the perpendicular displacement amount of a kind of both energy measurements roof and floor of design, energy measurement horizontal displacement again, three of the energy measurement offset direction parameter values also, and carry out a kind of new type measuring instrument table that observation is pressed in the ore deposit for high spud angle and high_dipping face.
Task of the present utility model realizes by following proposal: at first buried peg at the coal seam roof and floor, this measuring instrument fully contacted with the roof and floor measuring point and fixing after, when roof and floor is subjected to displacement, read the roof and floor relative shift in the reading hole (30) that the vertical bar (1) of living is located, locate the displacement of reading cover (14) read level direction at level bar alive (16), on annular dial plate (25), read the deflection angle value, thereby realize the purpose of a-table-multi-purpose.
The utility model will be further described below in conjunction with the accompanying drawing of being submitted to:
Accompanying drawing is the assembling synoptic diagram of roof and floor detector for displacement measuring, and it clamps friction seat (2) by vertical bar alive (1), spring (3), briquetting (4), handle (5), straight pin (6), rubber friction lining (7), screw (8), the vertical rod bush (9) of living, upper shield (10), spring (11), outer tube (12), attachment screw (13), reading cover (14), level rod bush (15) alive, level bar (16) alive, coupling bolt (17), rotation axis (18), annular table lid (19), angle scale (20), gauge stand (21), pointer (22), needle shaft (23), support ring (24), semi-circular organic glass table covers (25), sleeve (26), cramp bar (27), connecting bend (28), plug screw (29), reading hole (30) and peg fixed orifice (31) are formed.
Be carved with dimension line and gathering sill on the vertical bar (1) of living, be installed in the vertical rod bush alive (9), by the organic glass table illiteracy reading of data of reading hole (30), screw (8) plays guiding and restriction stroke to vertical bar alive (1).Vertical rod bush (9) upper end of living rubs seat (2) with being threaded with clamping, the lower end is twisted and is connect upper shield (10), and in the outer tube of packing into (12), plug screw (29) fuses the perpendicular displacement system up and down with attachment screw (13) with outer tube (12), and gives spring (11) certain initial stress values.The two ends of connecting bend (28) is twisted respectively and is connect plug screw (29) and cramp bar (27), and the middle part is fixing with level bar alive (16) with screw (8), thereby perpendicular displacement measuring system and horizontal shift measuring system are fused.In order to adapt to the measurement needs of different mining heights, can twist at the place of two ends up and down of connecting bend (28) and connect extension rod.Level is lived and to be carved with dimension line on the body of rod of bar (16), can be in level be lived rod bush (15) move left and right, reading cover (14) and level work rod bush (15) are with being threaded and playing the guiding role.Rotation axis (18) is connected with bolt (17) with level rod bush alive (15), and sleeve (26) supports, and its lower end and needle shaft (23) fuse.Two peg fixed orifices (31) are arranged at the bottom of gauge stand (21), angle scale (20) is fixed on the gauge stand (21), for ease of reading value of angular displacement, annular fenestra (referring to A to partial enlarged drawing) is arranged on the annular table lid (19), and be stained with semi-circular organic glass table and cover (25), when the relative base plate of top board rotated, pointer (22) relative angle scale (20) also just deflected, and promptly can read the offset direction angle value this moment.
Before the measurement, need to bury three benchmark pegs underground at roof and floor in advance, gauge stand (21) places on two measuring points of base plate, when handle (5) is in illustrated horizontal level, the bar (1) of will vertically living is extracted out, make its end closely contact measuring point on the top board, forward handle (5) to upright position downwards after, can pin the downslide of bar alive (1), topple over for avoiding device, regulate cramp bar (27) and fully contact with base plate, set up finish after, first three initial values that read respectively between the roof and floor measuring point.That is: perpendicular displacement is by reading hole (30) reading of data of vertical bar alive (1), horizontal shift is by reading cover (14) reading of data of level bar alive (16), offset direction between measuring point is covered (25) by semi-circular organic glass table and is read on angle scale (20) then by the sensing of pointer (22) on angle scale (20).When roof and floor generation relative displacement, the relative position of its measuring point also changes thereupon.At this moment read above-mentioned three parameter values again, the difference of front and back reading is the relative shift of roof and floor.
