Description
Technical field
The utility model belongs to the underground survey technical field, particularly relates to a kind of underworkings top board Surveying Control Point hanging point device.
Background technology
The tunnel Surveying Control Point in mine, down-hole all is arranged on the top board.Because base plate has pedestrian and haulage vehicle walking, the reference mark is as being arranged on the base plate, and is easily destroyed, is difficult for preserving.When arranging the reference mark, cut a hole the dark hole of a 20cm with jackdrill on back, hammer into timber in the hole, nail one iron nail on timber is reserved head of a nail 1cm and is hung cotton rope usefulness again.Hanging up cotton rope on the reference mark is a necessary preliminary work of surveying work.When operation was measured at the scene, survey crew need hang cotton rope on the head of a nail at reference mark, by cotton rope plumb bob is guided on the centre sign of transit, total powerstation or prism, thereby the coordinate that guarantees reference mark and centre was consistent.Now general height of tunnel is 3m, and some main ramp or head-room can reach 5m even higher, and obviously, depending merely on artificial hand-held cotton rope is can't be suspended on the so high top board.Traditional way is: (1) workman sets up the instrument of ascending a height such as ladder below the reference mark, gasoline can, instrument corner bracket etc., hand-held again cotton rope is climbed up the instrument of ascending a height, reach behind the height cotton rope tied up on the iron nail at reference mark and cotton rope is put down again, (2) utilize on-the-spot shovel installing to be equipped with, as scraper.The workman stands in the scraper bowl, waits scraper bowl to rise to reach behind the height cotton rope tied up on the iron nail at reference mark cotton rope to be put down again.Its shortcoming is: waste time and energy (1); (2) tumble injury easily takes place during instrument upper and lower ascending a height in the workman; (3) upper and lower the ascending a height of workman easily run into dc electric generation electric shock accidents in the tunnel during instrument; Just can't not hang cotton rope when (4) ascending a height instrument as the scene, causing measuring operation can't carry out.So hanging point is necessary whenever and wherever possible after just allowing survey crew enter the scene if any the instrument of need not anyly ascending a height.
Summary of the invention
The purpose of this utility model provides a kind of underworkings top board Surveying Control Point hanging point device, alleviates underground survey personnel's labour intensity, improves operating efficiency, prevents the generation of personal injury accidents such as tumble injury, electric shock, reduces the waste of manpower and materials.
The purpose of this utility model realizes by following technical proposals:
Underworkings top board Surveying Control Point hanging point device of the present utility model, it is characterized in that by front end metal hook group, the middle part coupling sleeve that is connected of front end metal hook group therewith, the coupling sleeve afterbody expansion link that is connected in middle part is formed therewith, and three parts are arranged in a linear.
The front end metal hook group of described front end metal hook group for forming by three metal hooks of vertically turning back, first back-turning section of three hooks of vertically turning back at grade, this plane is parallel with described coupling sleeve end face, and three metal hooks of vertically turning back become 120 ° of angles to arrange.
Described coupling sleeve is column type duroplasts coupling sleeve or hardwood coupling sleeve, and two ends respectively are provided with a hole, plugs with described front end metal hook group and afterbody expansion link respectively.
Described expansion link adopts fiberglass expansion link or carbon fiber expansion link, and the long 60-80cm of every pole, diameter 3--5cm are provided with 6--8 joint spiral expansion link.
Hanging point device of the present utility model is imitative fishing rod type.Its method for making is: prepare three iron leg silks when making the metal hook group earlier, be converted into a straight-line segment, two vertical back-turning section, form the hook of vertically turning back.Coupling sleeve is made of column type duroplasts or hardwood, and respectively draws a hole at two ends.Expansion link adopts the light materials of insulation such as fiberglass or carbon fiber to make.The long 60-80cm of every pole, diameter 3-5cm are provided with 6-8 joint spiral telescopic joint, and all length is about 120cm after the indentation, is similar to the afterbody of fishing rod.Three metal hook straight line portioies insert in the sleeve aperture during installation, and first back-turning section that makes three hooks of vertically turning back is on same plane, the plane, place is parallel with the coupling sleeve end face, become 120 ° of angles to arrange, with guarantee from arbitrarily angled can both hanging point, compacted if any the space with plastic foam, fix with seccotine then.The other end of expansion link inserts in the sleeve macropore, and is compacted with foam if any the space, fixes with seccotine then.Through top step, the hanging point device completes, and can come into operation.
Hand-holdable or be placed in the instrument pocket when survey crew enters the scene, when arriving the reference mark and thinking hanging point, regulate expansion link to appropriate length according to head-room, according to metal hook of angle Selection of iron nail on the timber of reference mark, the cotton rope head is drawn a knot that can be undone by a pull tie up on the hook, take cotton rope group on the other hand, take expansion link to lift on the other hand, when arriving the reference mark, knot that can be undone by a pull is tied up on the iron nail, extract metal hook out, cotton rope is transferred to the surveying instrument height naturally, hang up plumb bob, so far, hanging point work is finished.Just having measured operation after the instrument leveling centering.
The utility model light and handy (total length is about 120cm, and general assembly (TW) is about 1 kilogram) easy to carry is made simple, with low cost.Can under the situation of instrument of need not anyly ascending a height, finish hanging point work whenever and wherever possible, carry out the preliminary work of measuring operation.Thereby alleviate underground survey personnel's labour intensity, reduce the waste of manpower and materials, improve operating efficiency, prevent the generation of personal injury accidents such as tumble injury, electric shock.
