Abstract
Drum -type bore depth caliber belongs to measuring device in the water conservancy water and electricity field. It includes support, lining rope and weight, and its key technology is at a shelf location cylinder, twines rich lining rope on the cylinder, and weight, cylinder one end installation rocking handle are connected to lining rope one end, the weight is the hammer block of cavity, and hammer block cavity top is equipped with the ventilative eye of symmetry. The utility model discloses the beneficial effect who has is: the utility model discloses the weight is the hammer block of cavity, and the lining rope is in the positive center of weight, and the weight draws lining rope to appointed bore depth position, and the weight utilizes self weight to overcome downthehole underground and moves water and silt, boring mud influence, guarantees to transfer to the hole bottom, avoids the weight to receive the underground to move that water buoyancy and hole bottom silt boring mud influence and the measuring error that results in, has solved the difficult problem of bore depth precision measurement effectively. Ventilative eye assurance weight is transferred smoothly fast.
Description
Technical field:
Drum-type hole depth measuring appliance, belongs to measurement mechanism in field of water conservancy.
Background technology:
In engineering construction, geological prospecting work progress, often utilize drilling equipment to get out the column circular hole of all kinds of diameter and the degree of depth to underground, carry out bore operation.Because the impact of water and human factor is moved in geological conditions, underground, after boring when measuring hole depth, often comparatively big error can be produced.Especially for the bore operation that hole depth required precision is higher, the accurate measurement of hole depth is a kind of rigid index.
Summary of the invention:
Problem to be solved in the utility model is exactly provide a kind of measurement mechanism simple for above deficiency, the accurate hole depth measuring appliance of survey data.Its technical scheme is as follows:
A kind of drum-type hole depth measuring appliance, comprise support, lining rope and weight, its key technology is mounting rotary drum on support, cylinder twines rich lining rope, and lining rope one end connects weight, and rocking handle is installed in cylinder one end; Weight is the hammer body of hollow cavity, and hammer body hollow tip is provided with symmetrical breathable eye.
Long 15 ~ the 20cm of described weight.
Described lining rope adopts wire material, at lining rope upper marker scale.
Support is installed lining rope directive wheel.
Compared with prior art, the beneficial effect that the utility model has is:
1, the utility model weight is the hammer body of hollow cavity, lining rope lies in weight center, weight traction lining rope is to designation hole deep location, weight utilizes own wt to overcome underground in hole and moves water and mud, boring mud impact, guarantee is transferred at the bottom of hole, avoid weight to move mud boring mud at the bottom of water buoyancy and hole by underground to affect and the measure error caused, efficiently solve the difficult problem that hole depth is accurately measured.Breathable eye ensures that weight is transferred smoothly fast.
2, cylinder connection and control steel wire lining rope are transferred, for steel wire lining rope provides fulcrum.
3, steel wire lining rope is two millimeters of crude steel ropes, and upper marker scale can carry out large depth survey.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model heavy hammer structure schematic diagram;
Fig. 3 is Fig. 2 top view.
Detailed description of the invention:
See Fig. 1 ~ Fig. 3, the utility model comprises support 1, lining rope 5 and weight 4, it is characterized in that mounting rotary drum 2 on support 1, cylinder 2 twines rich lining rope 5, and lining rope 5 one end connects weight 4, and rocking handle 3 is installed in cylinder 2 one end; Weight 4 is the hammer body of hollow cavity, and hammer body hollow tip is provided with symmetrical breathable eye 7.
Long 15 ~ the 20cm of described weight.
At lining rope 5 upper marker scale.
Support 1 installs lining rope directive wheel 6 by angle steel.
After bore operation, in hole, transfer measuring appliance, weight radius is slightly less than borehole casing radius 2mm.Carry out hole depth by steel wire lining rope and invar tape accurately to measure.Hole depth thin portion data measured by invar tape, ensure certainty of measurement.
Measurement category: ± 60 °, aperture >=70mm.
Lining rope length makes according to maximum hole depth, controls preliminary surveying precision, and invar tape controls final measurement, solves high accuracy thin portion problem.
Weight weight, size, shape can adjust according to construction needs, can transfer to hole termination depth for principle.
