Description
Technical Field
The utility model relates to the field of machinary, specific theory involves a device for salvaging and digging the drill bit soon.
Background
At present, for the accidents of rotary drilling and drill dropping in a hole, two traditional coping strategies exist, the first strategy is that a professional diver dives into the hole, and a drill bit is directly hoisted out after being fastened by a steel wire rope, so that the mode has extremely high safety risk; the second type is to salvage the drill bit with the help of a specially-made screw manipulator, the device is a screw-type movable manipulator capable of being opened and closed in a rotating mode, the movable manipulator is installed on a rotary drilling rod and is lowered to the bottom of a hole with the help of the drilling rod, the manipulator is controlled to be opened and closed through the rotary drilling rod, and therefore the drill bit is grabbed and lifted out of the hole. Therefore, in the actual construction process, great uncertainty and potential safety hazard exist in the fishing drill bit.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a device for salvaging and digging the drill bit soon, the device can be very convenient salvage drill bit, reduces the safety risk.
The utility model provides a technical scheme that its technical problem adopted is: a device for salvaging a rotary drilling bit comprises a rotary drilling square sleeve, a connecting plate, a positioning plate and a salvaging hook; the rotary digging square sleeve is connected with a positioning plate through a connecting plate, and a fishing hook is arranged on the positioning plate; the positioning plate comprises a bottom plate and two side plates vertically arranged on the bottom plate, and through holes are formed in the side plates; the bottom of the fishing hook is conical and is provided with a barb.
In the structure, the fishing hook is provided with a through hole, and the fishing hook is arranged between the adjacent positioning plates by penetrating the through holes of the side plates and the through holes of the fishing hook through bolts.
In the structure, the rotary drilling square sleeve is provided with a connecting port and a pin hole;
the connecting port is used for extending a drill rod; the pin hole is used for a pin shaft and is used for realizing connection between the rotary drilling square sleeve and the drill rod.
In the above structure, the connecting plate is provided with a plurality of positioning plates.
In the structure, the spacing distance between the adjacent positioning plates is greater than the thickness of the fishing hook, so that the fishing hook can rotate.
The utility model has the advantages that: the device can very convenient salvage the drill bit, reduces safe risk.
Drawings
Fig. 1 is a schematic structural view of a device for salvaging a rotary drilling bit of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection relations related in the patent do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection auxiliary components according to specific implementation conditions. The utility model discloses each technical feature in the creation can the interactive combination under the prerequisite that does not contradict conflict each other.
Referring to fig. 1, the utility model discloses a device for salvaging rotary drilling bit, concretely, the device comprises a rotary drilling square sleeve 10, a connecting plate 20, a positioning plate 30 and a salvaging hook 40; the rotary drilling square sleeve 10 is connected with a positioning plate 30 through a connecting plate 20, and a fishing hook 40 is installed on the positioning plate 30.
The rotary drilling square sleeve 10 is provided with a connecting hole 101 for a drill rod to penetrate through, a pin hole 102 which is parallel and opposite to the drill rod is further formed in the rotary drilling square sleeve 10, a through hole is formed in the drill rod, and when the drill rod penetrates through the connecting hole 101 of the rotary drilling square sleeve, a pin shaft penetrates through the pin hole 102 of the rotary drilling square sleeve 10 and the through hole in the drill rod, so that the drill rod is fixedly connected with the rotary drilling square sleeve 10.
The positioning plate 30 is composed of a bottom plate 301 and two vertical side plates 302, the two vertical side plates 302 are installed on the bottom plate 301, and each side plate 302 is provided with a through hole 3021; arranging a plurality of positioning plates 30 on the connecting plate 20, arranging fishing hooks 40 between adjacent positioning plates 30, arranging through holes 401 on the fishing hooks 40, and using bolts to pass through the through holes 3021 on the side plates 302 and the through holes on the fishing hooks 40 to limit the fishing hooks 40; the distance between the two positioning plates 30 is greater than the thickness of the fishing hook 40, so that the fishing hook 40 can rotate around the bolt.
The bottom of the fishing hook 40 is conical and is also provided with a barb, and the surface of the fishing hook 40 is a smooth plane; inserting the drill rod into the rotary drilling square sleeve 10, and after firmly connecting the fishing device and the drill rod through a pin shaft, lowering the fishing device to a drill falling position in the hole by utilizing the drill rod; after the fishing hook 40 contacts the drill bit in the hole, because the bottom of the fishing hook 40 is conical and is a smooth plane, the fishing hook 40 can be opened towards two sides and then folded, the protruding part of the square sleeve of the drill bit is hooked through the barb, so that firm connection is formed between the fishing device and the drill bit, and then the drill bit is lifted out of the hole by lifting the drill rod through the rotary drilling rig.
While the preferred embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
