Description

A kind of anti-dieback bullet card positioning mechanism of more piece hinge type
Technical field
The present invention relates to a kind of cord coring drill, the anti-dieback bullet of the more piece hinge type of especially a kind of cord coring drill Card positioning mechanism.
Background technique
In order to grasp subsurface geology situation, true and reliable subterranean strata generally is directly obtained by way of the coring that drills Data, the drilling tool for using at most and being formed series at present is cord coring drill.Wire line core drilling technique has drilling efficiency High, the features such as labor intensity is low, construction cost is low, at present in troublesome zone drilling, Solid Mineral exploration, hydrogeologic prospecting etc. Numerous areas is widely applied.But in the prior art, the inner tube positioning mechanism of cord coring drill mainly includes steel ball Positioning and single locking position two ways of hinge joint bullet, wherein steel ball positioning method ball is that point or line contact with bullet card room, steel ball and Bullet card room local compression is serious, and steel ball surface is easily driven plain, and influences the rollback effect of steel ball, especially serious in core plugging When, bullet card room is very big by steel ball active force, and bullet card room easily expands, cracks, and lower drilling tool, drill bit are easy to fall off to bottom hole, makes At drilling accident;And single hinge joint bullet card is plane stress, since contact surface is plane, bullet card loses rotary space when blocking up the heart, Easily there is dieback phenomenon, interior pipe drilling tool can not be salvaged.
Summary of the invention
The present invention provides a kind of anti-dieback bullet card positioning mechanism of more piece hinge type, it is intended to solve in existing cord coring drill Lower drilling tool drill bit existing for pipe positioning mechanism falls off the problem of causing drilling accident and can not salvaging interior pipe drilling tool, reaches raising The drilling efficiency of cord coring drill, the purpose for reducing labor intensity of operating staff and drilling accident probability of occurrence.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of anti-dieback bullet card positioning mechanism of more piece hinge type, including recovery tube, play card holder, plate of pulling back, play clamp, play deck, Middle hinge, lower hinge, the first resilient key, the second resilient key, third resilient key, the 4th resilient key, the 5th resilient key and the 6th bullet Property pin;The recovery tube upper end and fishing spearhead component assembly, match in recovery tube and shoot card holder, and fix on the top of recovery tube First resilient key is installed, the 5th resilient key is fixedly mounted in the lower part of recovery tube;The bullet clamp include two calipers in left and right, left Right two calipers are by the second resilient key and play deck hinge mounted, pull back plate in two caliper upper end hinge mounteds;Left and right two It is hinged that a plate of pulling back also passes through the first resilient key;The middle hinge is connected to by third resilient key and plays deck bottom; The lower hinge is connected to the bottom of middle hinge by the 4th resilient key, and lower hinge bottom also passes through the 6th resilient key and plays card holder Hinge mounted.
The above-mentioned anti-dieback bullet card positioning mechanism of more piece hinge type, the card holder that plays are equipped with first cooperated with the first resilient key Long hole, the second long hole, the 6th resilient key pilot hole with the cooperation of the 5th resilient key, are additionally provided with and bullet card at left and right sides of card holder playing Clamp the elongated slot of cooperation;The caliper of left and right two for playing clamp may pass through the bullet that the elongated slot is installed on the outer pipe assembly of cord coring drill In card chamber interior walls.
The above-mentioned anti-dieback bullet card positioning mechanism of more piece hinge type is arranged and the cooperation of the 5th resilient key in the lower hinge Locking escape groove.
The above-mentioned anti-dieback bullet card positioning mechanism of more piece hinge type is additionally provided with reset spring and spring bearer plate, and is playing card holder Upper setting annular boss;The spring bearer plate, which is bolted on, plays card holder upper end;The reset spring is sleeved on bullet card holder It is assembled in a manner of precommpression positioned between spring bearer plate and the annular boss of bullet card holder, bullet is limited by reset spring in outside The relative position of the first resilient key and the 5th resilient key that are fixedly mounted in card holder and recovery tube.
The present invention be a kind of anti-dieback bullet card positioning mechanism of more piece hinge type, it use more piece hinge, can backing type knot Structure design in cord coring drill when the pipe plug heart, plays two calipers of clamp and adapter coupling is in dieback state, can lead at this time It crosses fishing spearhead component and pulls up recovery tube, make the first resilient key and the 5th resilient key respectively along the first long hole for playing card holder and the Two long holes move up, so that lower hinge be made to get rid of the position-limiting action of the 5th resilient key;Continue to pull up recovery tube, middle hinge Chain, lower hinge move down bullet two calipers of clamp, release caliper and adapter coupling relative to playing deck and playing card holder rotation Dieback state;Then two caliper recycling of clamp are played, interior pipe drilling tool and rock core can be promoted to by ground by salvaging mechanism.By This is as it can be seen that the present invention solves lower drilling tool drill bit existing for existing cord coring drill inner tube positioning mechanism falls off and cause in hole Accident and the problem of can not salvage interior pipe drilling tool, has reached and has improved the drilling efficiency of cord coring drill, reduces operator's labor The purpose of fatigue resistance and drilling accident probability of occurrence.The present invention also can also be used for the positioning of other complicated drilling tool inner tube assemblies, tool There are good practical value and market promotion prospect.
