Abstract
The invention relates to an expanding drill with a gate capable of being opened and closed transversely. The expanding drill comprises a barrel. The expanding drill is characterized in that the expanding drill further comprises a three-blade gate, a central tube, an upper sliding seat, a lower sliding seat, an oil cylinder, six connecting rods and cruciform joints; the interior of the barrel is hollow, three openings are evenly formed in the periphery of the side wall of the barrel, the gate is arranged on the opening of the side wall of the barrel and connected with the barrel through hinge pins and is capable of being opened and closed horizontally; the central tube is vertically arranged in the barrel, the oil cylinder is arranged in the central tube, the two ends of the oil cylinder are rotatably connected with the upper sliding seat and the lower sliding seat respectively, each two of the six connecting rods serve as one group, and the six connecting rods are divided into three groups; the three groups of the connecting rods are rotatably connected with the upper sliding seat and the lower sliding seat, the ends of the two corresponding connecting rods are rotatably connected through one cruciform joint, and the cruciform joints are fixedly connected with the gate. In this way, the oil cylinder stretches out and draws back to drive the connecting rods to stretch out and draw back, and therefore opening and closing of the gate are achieved. Accordingly, the expanding drill with the gate capable of being opened and closed transversely is simple and reliable in structure, maintenance is convenient, and the strengthening structure of the multiple connecting rods is adopted so that the gate can cope with variable-diameter hole operation of various geology.
Description
Technical field
The present invention relates to earth drilling field, be specially a kind of can the reamer of horizontal opening and closing shutter.
Background technology
The drill bit that the multiplex diameter of underground hole-forming operation is single, the different drill bit of use two diameters is then needed to carry out two subjobs when needing making reducing hole, so, need to dismantle drilling rod and assemble, thus labor intensive, material resources reduce the efficiency of bore operation.
In order to solve the problem, develop a kind of drill bit that tooth can be stretched out in real time when bore operation, and existing this kind of drill bit structure complexity, and without enough dynamics, cannot use at hardpan, cause its scope of application narrow.
Summary of the invention
The object of the invention is to, provide a kind of structure simple, there is sufficient intensity can the reamer of horizontal opening and closing shutter.
Can the reamer of horizontal opening and closing shutter, it comprises cylindrical shell, also comprises three fan brake doors, central tube, upper saddle, lower slider, oil cylinder, six roots of sensation connecting rod and cruciform joint, inner barrel hollow, sidewall has three openings with even circumferential, and described opening shape is identical with gate profile, and gate is located at cylinder lateral wall opening part and with cylindrical shell pinned connection and can horizontal opening and closing, central tube is vertically located in cylindrical shell, oil cylinder is located in central tube, the two ends of oil cylinder respectively with upper saddle, lower slider is rotationally connected, every two of six roots of sensation connecting rod is one group and is divided into three groups, these three groups of connecting rods respectively with upper saddle, lower slider is rotationally connected, particularly, often to organize in two connecting rods one to be rotationally connected with upper saddle, another root and lower slider are rotationally connected, the upper and lower two ends of central tube respectively have three openings, two connecting rods are rotationally connected by the end of cruciform joint by two connecting rods through after central tube up and down corresponding opening, cruciform joint is also fixedly connected with gate, so, oil cylinder flexible drive slide rotates and drivening rod stretches simultaneously, thus realize the opening and closing of gate, the edge of described gate is provided with cutting teeth.
The present invention adopts above-mentioned design, and it is simple and reliable for structure, thus easy to maintenance, adopts the reinforcement structure of many connecting rods, makes gate can tackle the reducing hole operation of various geology.

Detailed description of the invention
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of can the reamer of horizontal opening and closing shutter, it comprises cylindrical shell 1, also comprises three fan brake doors 7, central tube 3, upper saddle 2, lower slider 4, oil cylinder 5, six roots of sensation connecting rod 6 and cruciform joint 8, cylindrical shell 1 inner hollow, sidewall has three openings with even circumferential, and described opening shape is identical with gate 7 profile, and gate 7 is located at cylindrical shell 1 sidewall opening place and with cylindrical shell 1 pinned connection and can horizontal opening and closing, central tube 3 is vertically located in cylindrical shell 1, oil cylinder 5 is located in central tube 3, the two ends of oil cylinder 5 respectively with upper saddle 2, lower slider 4 is rotationally connected, every two of six roots of sensation connecting rod 6 is one group and is divided into three groups, these three groups of connecting rods 6 respectively with upper saddle 2, lower slider 4 is rotationally connected, particularly, often to organize in two connecting rods one to be rotationally connected with upper saddle 2, another root and lower slider 4 are rotationally connected, central tube about 3 two ends respectively have three openings, two connecting rods 6 are rotationally connected by the end of cruciform joint 8 by two connecting rods 6 through after the corresponding opening of central tube about 3, cruciform joint 8 is also fixedly connected with gate 7, so, the flexible drive slide of oil cylinder 5 rotates and drivening rod 6 stretches simultaneously, thus realize 7 opening and closings of gate, the edge of described gate 7 is provided with cutting teeth 9.
The present invention adopts above-mentioned design, and it is simple and reliable for structure, thus easy to maintenance, adopts the reinforcement structure of many connecting rods, makes gate can tackle the reducing hole operation of various geology.
