It is suitable for occasions with limited space such as tunnel construction.

The technical scheme adopted in the utility model is as follows:

An outrigger leg of a drilling rig, one end of the beam is fixed to a vertical oil cylinder, the other end is hinged to a support, through holes are opened on the upper surface of the beam, and several pin holes are opened on the upper plate of the support corresponding to the through holes, and the bolts pass through the through holes and the pins The holes position the beams.

As a further improvement of the above technical solution:

Several pin holes are circumferentially distributed on the upper plate along the central axis of the pin shaft.

The beam is a rectangular hollow beam.

The upper end surface of the beam is fixedly provided with a thickened piece.

A through hole is opened on the thickened sheet at a position corresponding to the through hole.

The piston rod of the vertical oil cylinder is fixedly connected with the bottom foot.

A drilling machine using the drilling machine legs, the support is fixed on the two sides of the drilling machine body.

As a further improvement of the above technical solution:

The beam can be rotated to be perpendicular or parallel to the drill body.

The beneficial effects of the utility model are as follows:

The crossbeam of the utility model is rotatably arranged on the support, and the support is fixedly arranged on both sides of the drilling rig. When the drilling rig is in use, the crossbeam is rotated and stretched to be perpendicular to the main body of the drilling rig to support the base of the drilling rig. Since only manual rotation of the crossbeam is required, no hydraulic pressure is required. Drive device, so the overall structure of the utility model is simple in design, the equipment is small in size, and can be applied to occasions with limited space such as tunnel construction; in addition, when the drilling rig is transported, the crossbeam can be rotated to be parallel and close to the drilling rig body, so that the overall size of the equipment Further reduction, the required transportation vehicles and transportation space are smaller, saving transportation costs.

Detailed ways

Below in conjunction with accompanying drawing, illustrate the specific embodiment of the present utility model.

As shown in Figure 1 and Figure 2, the utility model is fixedly installed on the side of the drilling rig body 11 through the support 1, the support 1 is hinged with the crossbeam 2 through the pin 4, the pin 4 and the crossbeam 2 are fixed by welding, and the crossbeam One end of 2 is fixed on the cylinder barrel of vertical oil cylinder 7 by fastening mode, and beam 2 can be centered on the central axis of pin shaft 4, drives vertical oil cylinder 7 to rotate. As shown in FIG. 5 and FIG. 6 , the beam 2 can be rotated to be perpendicular or parallel to the drilling machine body 11 . The piston rod of the vertical oil cylinder 7 is fixedly connected with the foot 3 at the bottom.

As shown in FIG. 2 , FIG. 3 and FIG. 4 , the beam 2 is a rectangular hollow beam, and the upper end plane of the beam 2 is provided with a through hole 8 . On the upper plate 10 of the support 1, a number of pin holes 6 are provided corresponding to the through holes 8, and some pin holes 6 are distributed along the central axis of the pin shaft 4 on the upper plate 10. When the crossbeam 2 drives the vertical oil cylinder 7 and the foot 3 After rotating to a suitable angle, use the bolt 5 to pass through the pin hole 6 and the through hole 8 to position the beam 2 on the support 1 . The position corresponding to the through hole 8 on the upper end surface of the beam 2 can also be provided with a thickening piece 9 by welding or other fastening means, in order to increase the contact area between the latch 5 and the crossbeam 2 connection, the thickening piece 9 is in the corresponding A corresponding through hole is opened at the position of the through hole 8 .

As shown in FIG. 5 , when in use, the foldable legs are arranged symmetrically on both sides of the drill body 11 , two pairs in this embodiment, and the support 1 is fixedly connected to the sides of the drill body 11 . After transporting the drilling rig to the construction site, adjust the position of the beam 2 according to the actual needs of the site, manually rotate the beam 2, and the beam 2 drives the vertical oil cylinder 7 on the outside and the foot 3 to rotate around the center of the pin shaft 4 to the required angle, and then plug it in. Latch 5 locates the utility model, and the crossbeam 2 stretched out in the present embodiment is perpendicular to the rig body 11, and the vertical oil cylinder 7 is elongated, and the foot 3 supports the rig body 11 on the ground, and the rig starts working.
