Description

The rectangular opening trepan
Technical field
The utility model relates to a kind of trepan, particularly the rectangular opening trepan used of a kind of subterranean well.
Background technology
At present, the trepan that drilling well is used all is that the rotation by drill bit drills through a circular wellhole, and some engineering need drill through some rectangular openings, and traditional rig is just helpless.
Summary of the invention
The utility model has remedied above blank, and a kind of rectangular opening trepan is provided.
The utility model is achieved by the following technical solution:
A kind of rectangular opening trepan, the drilling rod that comprises top, the drilling rod lower end is connected with motor, and motor housing is fixed in brace summer, and the output shaft of motor is connected in the driving drilling rod, drive the drilling rod lower end and be fixed with bevel gear, bevel gear is meshing in gear wheel, and the gear wheel center of circle is provided with rotating shaft, and an end of rotating shaft is provided with skewback, the other end of rotating shaft is fixed in the connecting rod lower end, and brace summer is fixed in the connecting rod upper end; Edge, gear wheel outer ring is provided with a bearing pin, hang with coupler body on the bearing pin, coupler body is fixed in the upper end of connecting rod, and the lower end of connecting rod is articulated in slide mass, and slide mass the right and left respectively is fixed with two sliding sleeves, on the guide rod of two sliding sleeve cover on the left sides on the left side, on two sliding sleeve covers guide rod on the right on the right, brace summer is fixed in two guide rod upper ends, and two lower end of the guide rod are respectively equipped with limited block, the slide mass lower end is connected in hammer body by contiguous block, and the hypophysis lower end is provided with several impact knives.
The utlity model has following characteristics:
The utility model can orthogonal hole body by rectangle hammer body hammering stratum.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A view;
Among the figure: 1, drilling rod, 2, motor, 3, drive drilling rod, 4, bevel gear, 5, brace summer, 6, gear wheel, 7, skewback, 8, guide rod, 9, extension spring, 10, push rod, 11, sliding sleeve, 12, limited block, 13, slide mass, 14, contiguous block, 15, hammer body, 16, impact knives, 17, rotating shaft, 18, bearing pin, 19, coupler body, 20, connecting rod, 21, the borehole wall, 22, connecting rod.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment comprises the drilling rod 1 on top, the drilling rod lower end is connected with motor 2, and motor housing is fixed in brace summer 5, and the output shaft of motor is connected in driving drilling rod 3, drive the drilling rod lower end and be fixed with bevel gear 4, bevel gear is meshing in gear wheel 6, and the gear wheel center of circle is provided with rotating shaft 17, and an end of rotating shaft is provided with skewback 7, the other end of rotating shaft is fixed in connecting rod 22 lower ends, and brace summer is fixed in the connecting rod upper end; Edge, gear wheel outer ring is provided with a bearing pin 18, hang with coupler body 19 on the bearing pin, coupler body is fixed in the upper end of connecting rod 20, the lower end of connecting rod is articulated in slide mass 13, slide mass the right and left respectively is fixed with two sliding sleeves 11, on the guide rod 8 of two sliding sleeve cover on the left sides on the left side, on two sliding sleeve covers guide rod 8 on the right on the right, brace summer is fixed in two guide rod upper ends, two lower end of the guide rod are respectively equipped with limited block 12, the slide mass lower end is connected in hammer body 15 by contiguous block 14, and the hypophysis lower end is provided with several impact knives 16.
Be the accurate return of energy after connecting rod is swung to the right, the connecting rod bottom is provided with an extension spring 9, and the upper end of extension spring is articulated in connecting rod, and the lower end is articulated in slide mass, and the extension spring bottom is provided with a push rod 10, and slide mass is fixed in the lower end of push rod.
During the utility model work, motor drives gear wheel and rotates counterclockwise as the center of circle take rotating shaft by driving drilling rod, bevel gear, bearing pin on the gear wheel is in rotation process, drive coupler body, connecting rod, slide mass, contiguous block, hammer body rise together, when bearing pin drives coupler body arrival gear wheel top, owing to being subjected to stopping of gear wheel intermediate rotary shaft, bearing pin turns over rear coupler body and namely breaks off relations and slide along skewback, hammer body that is fall the hammering stratum repeats above the action, so repeatedly when bearing pin forwards Fig. 1 position to.
