Description
Technical field
The utility model relates to a kind of mining telescopic formula scriber, is particularly useful for the setting-out construction of coal mine roadway center line.
Background technology
China's overwhelming majority colliery belongs to underground mine, pit mining need go out various paths by Drilling between earth's surface and coal body, be used for transporting coal, ventilation, draining, pedestrian and for the new various necessary preparation engineerings of digging of coal excavation apparatus extraction coal etc., these paths are referred to as coal mine roadway.
Laneway midline is the Direction Line of indication tunnelling direction.Be mainly used in needing straight line construction tunnel or directed construction tunnel, to guarantee that tunnel is along straight line and design orientation driving.Middle live width 50mm left and right, paints or limewash brushes out at top, tunnel.
In time, draw accurately laneway midline to ensure tunnel safety, accurately construct significant.At present down-hole technical staff is when drawing top, tunnel center line, often, by waddy on hand, anchor pole, hammer drill etc., hairbrush tied up in its one end as line tool.When head-room is larger, must stand in belt feeder, mine car, rake cash machine etc. upper, this increased undoubtedly technical staff labour intensity, bring potential safety hazard, cannot guarantee the accuracy of drawn center line simultaneously.
Utility model content
For solving the defect of existing laneway midline construction technology, the utility model provides a kind of mining telescopic formula scriber, and its length can arbitrarily regulate, and draws center line fast, accurately.
The utility model technical solution problem adopts following scheme:
Mining telescopic formula scriber, comprise by the extension type body of rod, locking device, top several parts of detachable hairbrush and forming, it is characterized in that: the body of rod is made by aluminium alloy, the body of rod adopts segmented not wait bore sleeve design, the segmentation body of rod can be twitched along another segmentation body of rod in its length range, locking device is located at body of rod one end, and hairbrush is fixed by screws in scriber top.
Described locking device is made by ABS engineering plastics, locking device is comprised of locking jacket and locking inner sleeve two parts, locking jacket is being locked on inner sleeve by screwed, locking inner sleeve is fixed in segmentation body of rod upper end, locking inner sleeve top consists of four lobe formula cones, and locking jacket inside upper part is provided with the overcoat conical surface corresponding with lobe formula cone.
Described locking jacket surface is provided with the spill striped of anti-skidding effect, when regulating scriber length, the pull segmentation body of rod, to appropriate length position, screws locking jacket clockwise, and the overcoat conical surface is along lobe formula cone down sliding, make lobe formula cone inwardly push the segmentation body of rod, the segmentation body of rod is locked and cannot twitches again, screws counterclockwise locking jacket, and the overcoat conical surface is along lobe formula cone upward sliding, lobe formula cone loses extruding and restores to the original state, and the release of the segmentation body of rod can freely be twitched.
The beneficial effects of the utility model are not wait bore sleeve design, locking device etc. by adding segmented, scriber compact conformation is easy to carry, length can regulate arbitrarily according to head-room, draw center line fast, accurately, without by other equipment and equipment, eliminated potential safety hazard, alleviated technical staff's labour intensity.

The specific embodiment
In order better to understand the utility model, allow mine technology personnel grasp fast the using method of mining telescopic formula scriber, below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1: a kind of mining telescopic formula scriber, comprise by the extension type body of rod 1, locking device 2, detachable hairbrush more than 3 parts in top and forming, it is characterized in that: the described body of rod 1 is made by aluminium alloy, the body of rod 1 adopts segmented not wait bore sleeve design, the segmentation body of rod can be twitched along another segmentation body of rod in its length range, locking device 2 is located at body of rod one end, and hairbrush 3 is fixed on scriber top by screw 4.
As shown in Figure 2 and Figure 3: described locking device 2 is by being made by ABS engineering plastics, locking device 2 is comprised of locking jacket 21 and locking inner sleeve 22 two parts, locking jacket 21 is being locked on inner sleeve 22 by screwed, locking inner sleeve 22 is fixed in segmentation body of rod upper end, locking inner sleeve 22 tops consist of four lobe formula cones 24, and locking jacket 21 inside upper part are provided with the overcoat conical surface 23 corresponding with lobe formula cone 24.
As shown in Figures 1 to 4: described locking jacket 21 surfaces are provided with the spill striped of anti-skidding effect, when regulating scriber length, the pull segmentation body of rod is to appropriate length position, screw clockwise locking jacket 21, the overcoat conical surface 23 is along lobe formula cone 24 down slidings, make the inwardly extruding segmentation body of rod of lobe formula cone 24, the segmentation body of rod is locked and cannot twitches again, screw counterclockwise locking jacket 21, the overcoat conical surface 23 is along lobe formula cone 24 upward slidings, lobe formula cone 24 loses extruding and restores to the original state, and the release of the segmentation body of rod can freely be twitched.
