Abstract
The utility model discloses a double-jaw rod disassembling device for an in hole drilling machine. A lower rod disassembling device body (12) is fixedly arranged on a drilling frame (15), and the lower rod disassembling device body (12) is axially connected with an upper rod disassembling device body (4) in a rotating way. An upper jaw which is driven by an upper clamping rod cylinder is axially and symmetrically arranged on the upper rod assembling device body (4), and a lower jaw which is driven by a lower clamping rod cylinder is axially and symmetrically arranged on the lower rod disassembling device body (12). One end of a rod disassembling cylinder (1) is hinged on the drilling frame (15), and the other end is hinged with the upper rod disassembling device body (4). The utility model is the double-jaw rod disassembling device for an in hole drilling machine, the utility model has the advantages that automatically assembly and disassembly of a drilling rod can be realized, the decrease of auxiliary operation can be realized, the labor intensity of workers can be lightened and the hole drilling efficiency is improved.
Description
Technical field
The utility model relates to a kind of rod disassembling device, particularly relates to the two jaw rod disassembling devices of a kind of down-the-hole drill.
Background technology
The novel down-the-hole drill of the high blast of integrated hydraulic, be a kind of metallurgy that is widely used in, the mine, building materials, coal, railway, highway, construction of hydropower facilities, engineering explosion hole drills such as the national defense construction and cubic metre of earth and stone cutter construction equipment, in use, to longhole drilling, usually all need the connecting and disconnecting drill rod operation, when main drilling rod pierces, from drill pipe storage, get a joint pair drilling rod and connect the continuation Drilling, reach requirement until hole depth, will pay drilling rod again and unload and send drill pipe storage back to, in unloading the bar operation, because connecting screw thread between the drilling rod rotates tighter in boring procedure, with artificial craft drilling rod is unloaded, need be by more instrument, time that cost is long and stronger labour intensity.When in this external boring procedure lock of tool drilling taking place, run into the difficulty of rotary torque deficiency when handling usually.
The utility model content
Technical problem to be solved in the utility model provides a kind of unloading automatically of drilling rod of realizing, realizes reducing subsidiary operation time, alleviates hand labor intensity with the two jaw rod disassembling devices of the down-the-hole drill that improves drilling efficiency.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: following rod disassembling device body is packed on the drilling cramp, described rod disassembling device body down adopts coaxial rotation to connect with upper rod unloading device, on described upper rod unloading device, axially be arranged with the upper jaw that drives by upper jamming rod jar, on described rod disassembling device body down, axially be arranged with the lower jaw that drives by lower jamming rod jar, unload bar cylinder one end and be hinged on the described drilling cramp, the other end and described upper rod unloading device are hinged.
Axially be arranged with lower-left jaw that drives by the lower-left jamming rod and the bottom right jaw that drives by the bottom right jamming rod on the described rod disassembling device body down, axially be arranged with upper left jaw that drives by upper left jamming rod and the upper right jaw that drives by upper right jamming rod on the described upper rod unloading device, described bar cylinder one end that unloads is hinged on the described drilling cramp, and the other end and described upper left jamming rod are hinged.
Described upper rod unloading device rotates by interior China and foreign countries rotating ring with described rod disassembling device body down and connects.
Adopt the two jaw rod disassembling devices of down-the-hole drill of technique scheme, lower jamming rod jar effect promotion lower jaw slides in following rod disassembling device body and closes up drilling rod (or impactor) clamping down when unloading bar, simultaneously upper jaw in upper rod unloading device by the upper jamming rod jar effect promote lower slider close up with on drilling rod (or short circuit head) clamp, unload the action of bar cylinder then, make upper jaw drilling rod on clamping obtain the moment that relatively rotates simultaneously, thereby realize the loosening of drilling rod connecting thread up and down drilling rod down.After connecting thread is loosening, can realize unloading fast of drilling rod by slew gear.This rod disassembling device unloads the bar mode with traditional-handwork and compares, and has following characteristics and function: 1, two-layer up and down jaw structure, and four kelly hydraulic cylinder synchronous lockings, chucking power is big and reliable; 2, the hydraulic locking manoeuvrable is light, and hydraulic system can realize the size adjustment of chucking power; 3, double-deck jaw has been guaranteed effective guiding of drilling rod in perforate and the drilling process; 4, can conveniently realize the automatically reliable dismounting of drilling rod, reduce hand labor intensity greatly; 5, lock of tool drilling aid in treatment function.
In sum, the utility model is a kind of unloading automatically of drilling rod of realizing, realizes reducing subsidiary operation time, alleviates hand labor intensity with the two jaw rod disassembling devices of the down-the-hole drill that improves drilling efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model vertical view.
The specific embodiment
Following structure the drawings and specific embodiments elaborate to the utility model.
Referring to Fig. 1 and Fig. 2, axially be arranged with lower-left jaw 11 that drives by lower-left kelly 14 and the bottom right pincers 9 that drive by bottom right jamming rod 8 on the following rod disassembling device body 12, axially be arranged with upper left jaw 3 that drives by upper left jamming rod 2 and the upper right jaw 6 that drives by upper right kelly 7 on the upper rod unloading device 4, unloading bar 1 one ends is hinged on the drilling cramp 15, the other end and upper left jamming rod 2 are hinged, and upper rod unloading device 4 rotates by interior China and foreign countries rotating ring 13 with following rod disassembling device body 12 and connects.
Lower-left jamming rod 14 drives lower-left jaws 11 and drives bottom right jaws 9 by bottom right jamming rod 8 and slides in rod disassembling device body 12 down and close up drilling rod 10 (or impactor) clamping down when unloading bar, simultaneously upper left kelly 2 drive upper left jaws 3 and upper right jamming rod 7 drive upper right jaw 6 upper rod unloading device 4 in, slide close up with on drilling rod 5 (or short circuit head) clamping, unload bar 1 action then, make upper left jaw 3 and upper right jaw 6 drilling rod 5 on clamping obtain the moment that relatively rotates simultaneously, thereby realize the loosening of drilling rod connecting thread up and down drilling rod 10 down.After connecting thread is loosening, can realize unloading fast of drilling rod by slew gear.In when, in the Drilling bit freezing taking place when, can utilize rod disassembling device left and right sides kelly jaw (3,6) to clamp drilling rod, unclamp attitude, unload 1 action of bar cylinder then and descend rod disassembling device left and right sides kelly jaw (9,11) to be in, can significantly improve rotary torque and overcome slew gear torque deficiency, be convenient to bit freezing and handle.
