Abstract
The utility model discloses a get core machine drill head with core appearance ejecting device comprises drill bit, two reinforcing bars and a circular rubber steel sheet, and circular rubber steel sheet is placed in the drill bit, and its diameter is lighter than drill bit interior diameter 10mm, drill out two holes in the position of drill bit top surface symmetry, two holes closely spaced in the diameter of rubber steel sheet. Use the utility model discloses can reduce the destruction to core appearance, ensure the integrality of core appearance, improve work efficiency, ensure the authenticity of data.
Description
Technical field
The utility model relates to a kind of instrument, is directly involved in for various concrete core boring sampling instrument in the constructions such as road, building, harbour, airport.
Background technology
Carry out in core boring sampling operating process at current cement concrete constructions, bituminous concrete pavement, the core drilled through often " card " inside drill bit, and " card " probability inside drill bit is more than 70%.The way often taked is exactly beat the outer wall of drill bit lightly with hammer or other object, by vibrations, allows core fall out at leisure.This its shortcoming of mode of beaing outer wall is: core beats by vibrations process at outer wall, be easy to loose, break, cause core to use, cause core boring sampling again, while a large amount of human and material resources of waste, also often cause drill through core data inaccuracy, even can not use.
Summary of the invention
The purpose of this utility model is exactly the concrete coring machine drill bit that will provide a kind of improvement, can reduce the destruction to core, makes the percentage of head rice of core higher, thus the authenticity of data of increasing work efficiency, guarantee.
The purpose of this utility model is achieved in that a kind of corning machine drill bit with core ejecting device, and be made up of drill bit, two reinforcing bars and one block of round rubber steel plate, round rubber steel plate is placed in drill bit, and its diameter is less than bit inside diameter 10mm; Get out two circular cavities in the position of drill bit end face symmetry, the spacing of two circular cavities is less than the diameter of rubber steel plate.
As further scheme of the present utility model, reinforcing bar inserts in hole, and length is not less than 50cm, and is two Φ 8 reinforcing bars with length, polishes in two ends; Rubber steel plate thickness 7mm, the thickness of its light plate is 3mm, the rubber of steel plate outer wrapping thickness 2mm.
" push away " from drill bit internal the way going out core because the utility model adopts, and utilize the destruction of rubber steel plate minimizing to core, make the percentage of head rice of core higher, thus the authenticity of data of increasing work efficiency, ensure that.
accompanying drawing explanationaccompanying drawing 1 is structural representation of the present utility model, further illustrates the utility model below in conjunction with accompanying drawing.
embodimentaccompanying drawing shows the structure of the utility model with the corning machine drill bit of core ejecting device, and be made up of drill bit 4, two reinforcing bars 1 and one block of round rubber steel plate 3, round rubber steel plate 3 is placed in drill bit 4, and its diameter is less than drill bit 4 interior diameter 10mm; Get out two circular cavities 2 in the position of drill bit 4 end face symmetry, the spacing of two circular cavities 2 is less than the diameter of rubber steel plate 3, and the size of hole 2 should ensure that reinforcing bar 1 freely passes in and out.
Reinforcing bar 2 inserts in hole, and length is not less than 50cm(reinforcing bar length and is greater than more than crown height 10cm), and be two Φ 8 reinforcing bars with length, polish in two ends; Rubber steel plate 3 top and bottom are parallel, thickness 7mm, and the thickness of its light plate is 3mm, the rubber of steel plate outer wrapping thickness 2mm, the diameter of rubber steel plate 3 be less than drill bit 4 interior diameter 10mm(drill bit 4 interior diameter mate with the size of rubber steel plate 3 diameter see the following form).
| Bit inside diameter (mm) | 50 | 75 | 100 | 150 | 200 |
| The rubber steel board diameter (mm) mated with drill bit | 40 | 65 | 90 | 140 | 190 |
Using method of the present utility model: select the position needing core boring sampling, fixing rig, the faying face of decline drill bit 4 to core boring sampling position, sphere shaped markup is drawn with chalk around drill bit 4, promote more than drill bit 5cm, rubber steel plate 3 is placed in the middle of the sphere shaped markup made of chalk, be moved during holing to prevent rubber steel plate 3, in the bottom surface of rubber steel plate 3 and the double faced adhesive tape adhesion of core end face, then, decline drill bit 4, to the faying face drilling through position, confirms that rubber steel plate 3 is completely within drill bit 4.
Start a machine and start boring, at the end of boring, promote drill bit 4 to faying face, observe core 5 whether in drill bit 4, if core is inner at drill bit 4, then boring is left in the planimetric position of moving drill bit 4, in case core 5 sample falls to entering boring suddenly.Then, by two reinforcing bars 1 from top to bottom from the interior vertical insertion drill bit 4 of the hole 2 that drill bit 4 is reserved, the bottom of reinforcing bar 1 is made just in time to withstand on the end face of rubber steel plate 3, symmetrical with hammer, slightly to knock two reinforcing bars 1 downwards top, like this, produce downward thrust to rubber steel plate 3, core 5, under the thrust of rubber steel plate 3, is gently released downwards by drill bit 4.In the process that core 5 is pushed out, with manually holding core 5 in core 5 bottom surface, the damage in order to avoid core 5 falls suddenly; Meanwhile, along with the slow release of core 5, correspondingly promote drill bit 4, until core 5 is all pushed out.After core 5 is pushed out, takes out reinforcing bar 1 and rubber steel plate 3, clean up, in order to using again.
The utility model is applicable to the core drilling through diameter 50mm ~ 200mm.
