Abstract
A layout conductor point used for coal mine underground measurement is a copper cylindrical structure. An end face axis is arranged with a hole with wire, a cylinder of the other end is arranged with a groove, the groove bottom is a plane, and a via suppository line used for measuring point is arranged between the groove bottom and the end face of the cylinder. When installed, shoot nail is nailed on roof by nail-shooting gun, with the measuring point which has been processed sleeved on and tightened, and fixed by anchor agent at last. The installation of the utility model is convenient, the installation of measuring point uses beating electric drill or pneumatic drill, but main road way is difficult to be connected with air duct and water pipe, even affecting the producing. The utility model has the advantages of safety, reliability, saving manpower and material resources, and getting the purpose of recovering mine permanent control point accuracy.
Description
One, technical field
The utility model relates to measuring laying traverse point under a kind of coal mine.
Two, background technology
The permanent pilot point of measurement that underground survey is at present used with steel plate processing, has triangle, straight plate shape is arranged, crooked shape is arranged, use very inconveniently, more because disadvantage is the down-hole humidity, water is arranged that the time rots once long getting rusty, and just can not re-use.Another is that the down-hole sets up an office all is to be embedded on the back, and these measuring points are buried underground very inconveniently at present, need employ digging team and draw a few km airducts, water pipe, draw the brill perforating.The non-corrosive time of rotting has been grown also easy deformation in addition, do not reach and measure high accuracy, high standard, will spend and other unit to measure if re-use from new orientation, human and material resources, financial resources had so both been wasted, influenced the ore deposit safety in production again, can not satisfy the needs of Coal Production, can be when serious to causing very large economy loss on the ore deposit.
Three, summary of the invention
The technical problems to be solved in the utility model is: design measuring laying traverse point under a kind of coal mine, to solve the problem that prior art exists.
Implementation procedure of the present utility model is: it is a cylindrical structural, and at one end there is the hole of a band silk at the place, axle center; A groove is arranged on the cylinder of the other end, and bottom land is a plane and parallel with end face, and a through hole is arranged between bottom land and cylindrical end face.In order to prevent corrosion, the utility model adopts copper cylinder.
Good effect of the present utility model is: easy for installation, measuring point was installed in the past, and use and to make electric drill or air drill, but give a dinner for a visitor from afar now in big lane, the unusual difficulty of water pipe or cable, even influence production; The utility model is safety, reliable both, saves human and material resources, has reached the purpose of recovering permanent control point, ore deposit precision again.
Four, description of drawings
Accompanying drawing 1 is a schematic diagram of the present utility model; Accompanying drawing 2 is the vertical view of Fig. 1.
Five, embodiment
Shown in accompanying drawing 1, accompanying drawing 2, the utility model adopts the copper cylinder of diameter 16-20mm, long 40-60mm, and at one end the hole 1 of a band silk, aperture 8mm, hole depth 20mm bore in the place, axle center; Tilt downwards apart from 5 millimeters places of end face at the cylinder 3 of the other end, a groove 4 is arranged, bottom land is a plane, and the through hole 5 of a diameter 1mm is arranged between the end face of bottom land and cylinder 3, fastens line and does measuring point and use; Better fixing on top board for measuring point, an end with holes is processed four grooves 2 vertically on cylinder 3 outer walls, and its dark 2 millimeters, long 15 millimeters.
In use, on the top, tunnel, nailing is pinned on the top board, the utility model that processes is enclosed within on the nailing tightens again, use anchoring agent anchoring real at last with ail gun.
Claims (3)
