Detailed Description
The following detailed description of the present invention is provided with reference to the accompanying drawings and examples, but not to be construed as limiting the present invention in any way.
Referring to the attached drawing 1, the tool for clamping the circular tube is used for clamping the circular tube when drilling holes on the circular tube, and can be used for drilling holes at two ends of a grouting sleeve.
The tool comprises a bottom plate 1, a linear driving mechanism, an angle-shaped connecting rod 4, a rotating support 3 and a positioning base 6, wherein the bottom plate 1 is a rectangular steel plate, more than two threaded holes are formed in one end of the bottom plate along the wide edge of the rectangular steel plate, the contour of the positioning base 6 is cuboid, a V-shaped groove with an upward opening is formed in the upper portion of the positioning base 6 along the length direction of the positioning base, a rectangular sinking groove is formed in the bottom of the V-shaped groove, a through hole corresponding to the threaded hole is formed in the rectangular sinking groove, and a fixing screw penetrates through the through hole and is connected with the threaded hole to fix the positioning base 6 on the bottom plate 1; the linear driving mechanism can select an air cylinder 2 or an electric push rod, in this embodiment, the linear driving mechanism is preferably an air cylinder 2, a cylinder body of the air cylinder 2 is fixed on the bottom plate 1, a moving direction of a piston rod of the air cylinder is perpendicular to a length direction of the positioning base 6, and further preferably, the air cylinder 2 is installed on a perpendicular bisector of the positioning base 6; the rotating support 3 comprises a vertical section 301 and an inclined section 302 which are integrated, the bottom of the vertical section 301 is fixed on the bottom plate 1 through a screw, the top of the vertical section 301 extends towards the cylinder 2 in an inclined mode to form the inclined section 302, the inclined section 302 is composed of two parts which are separated, parallel and symmetrical, a movable space 303 of the angle-shaped connecting rod 4 is formed between the two parts, and a connecting hole is formed in the top end of the inclined section 302; the angle type connecting rod 4 comprises a connecting end 401 and a clamping end 403, a corner part 402 of the angle type connecting rod 4 is an obtuse angle, namely, an included angle between the connecting end 401 and the clamping end 403 is an obtuse angle, the corner part 402 is rotatably arranged on a connecting hole at the top end of the inclined section 302 and is positioned in a movable space 303 between two parts forming the inclined section 302, the connecting end 401 of the angle type connecting rod 4 is hinged with a piston rod of the air cylinder 2, and the clamping end 403 of the angle type connecting rod 4 is positioned above the V-shaped groove.
Further, the distance from the end surface 401 of the connecting end to the corner 402 of the angle-type connecting rod 4 is smaller than the distance from the end surface 403 to the corner 402, so that the clamping end 402 has a larger moving range to adapt to a round pipe 5 with a larger diameter.
