Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the utility model discloses a support 1 fixed mounting is on the side of rig body 11, and support 1 is articulated through round pin axle 4 and crossbeam 2, and round pin axle 4 passes through welded mode with crossbeam 2 and fixes, and the one end of crossbeam 2 is passed through the fastening mode and is fixed on the cylinder of perpendicular hydro-cylinder 7, and crossbeam 2 can use the axis of round pin axle 4 as the center, and it is rotatory to drive perpendicular hydro-cylinder 7. As shown in fig. 5, 6, the beam 2 can be rotated to be perpendicular or parallel to the drill body 11. A piston rod of the vertical oil cylinder 7 is fixedly connected with the bottom foot 3.
As shown in fig. 2, 3 and 4, the cross beam 2 is a rectangular hollow beam, and a through hole 8 is formed on the upper end plane of the cross beam 2. A plurality of pin holes 6 are formed in an upper flat plate 10 of the support 1 corresponding to the through holes 8, the pin holes 6 are circumferentially distributed on the upper flat plate 10 along the central axis of the pin shaft 4, and after the cross beam 2 drives the vertical oil cylinder 7 and the bottom foot 3 to rotate to a proper angle, the cross beam 2 is positioned on the support 1 by a bolt 5 penetrating through the pin holes 6 and the through holes 8. The through hole 8 of the upper end face of the cross beam 2 can be correspondingly provided with a thickening sheet 9 in a welding or other fastening mode so as to increase the contact area of the joint of the bolt 5 and the cross beam 2, and the thickening sheet 9 is correspondingly provided with a through hole in a position corresponding to the through hole 8.
As shown in fig. 5, when in use, the foldable legs are symmetrically arranged on two sides of the drilling machine body 11, in this embodiment, two pairs of the foldable legs are arranged, and the support 1 is fixedly connected with the sides of the drilling machine body 11. After transporting the construction site with the rig, according to the position of on-the-spot actual need adjustment crossbeam 2, manual rotatory crossbeam 2, crossbeam 2 drive perpendicular hydro-cylinder 7 and footing 3 in the outside around 4 central rotations of round pin axle to required angle after, plug in bolt 5 will the utility model discloses the location, 2 perpendicular to rig bodies 11 of crossbeam after stretching out in this embodiment, perpendicular hydro-cylinder 7 extends, and footing 3 supports rig bodies 11 subaerial, and the rig begins the operation. As shown in fig. 6, when the drilling machine needs to be transported, the vertical oil cylinder 7 drives the bottom foot 3 to contract, when the bottom foot 3 leaves the ground, the bolt 5 is pulled out, the cross beam 2, the vertical oil cylinder 7 on the outer side and the bottom foot 3 rotate around the center of the pin shaft 4 to be parallel and abut against the drilling machine body 11, and then the bolt 5 is inserted to position the cross beam 2 for transportation.
