DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1, reference Figures 1 to 5A stabilizing device for a rotary drilling rig comprises a hydraulic cylinder 1, a main base plate 2 is installed at the output end of the hydraulic cylinder 1, two groups of cross bars 3 are fixedly connected to the main base plate 2, the two groups of cross bars 3 are slidably connected to the two groups of auxiliary base plates 4, the auxiliary base plates 4 can slide laterally at the two groups of cross bars 3, the two groups of auxiliary base plates 4 are rotatably connected to a first rod body 5 through a connecting shaft, and multiple groups of first rod bodies 5 are rotatably connected to two groups of second rod bodies 6 through connecting shafts. When the second rod bodies 6 are in contact with the ground in advance, the first rod bodies 5 will be pulled to push the auxiliary base plates 4 outward, thereby increasing the contact range of the main base plate 2 and the two groups of auxiliary base plates 4 with the ground, vertical rods 8 are fixedly connected to the two groups of second rod bodies 6, and the outer walls of the two groups of vertical rods 8 are slidably connected to a sleeve body 7, the vertical rod 8 can be lifted and slid in the sleeve body 7, and the vertical rod 8 is used to The second rod body 6 is guided for lifting and moving, so that when the second rod body 6 contacts the ground, it can pull the first rod body 5 to stably push the auxiliary bottom plate 4 away from the main bottom plate 2. The two sets of sleeves 7 are fixedly connected to the main bottom plate 2, and the first ring body 10 is fixedly connected to the two sets of sleeves 7. When the hydraulic cylinder 1 drives the main bottom plate 2 and the auxiliary bottom plate 4 to contact the ground, the second rod body 6 will contact the ground in advance. At this time, because the main bottom plate 2 and the auxiliary bottom plate 4 are continuously pressed downward, the second rod body 6 can pull the first rod body 5 to push the auxiliary bottom plate 4 to move away from the main bottom plate 2. When the main bottom plate 2 and the two sets of auxiliary bottom plates 4 contact the ground, the occupation range of the main bottom plate 2 and the two sets of auxiliary bottom plates 4 and the ground will be expanded, which can further increase the overall stabilizing effect on the rotary drilling rig and ensure the working stability of the rotary drilling rig.

[0023] In this embodiment, the two sets of sleeve bodies 7 are threadedly connected with bolts 11, and the two sets of vertical rods 8 are processed with grooves 12. When the cross bar 3 contacts the ground, the sleeve body 7 will move down with the main bottom plate 2 at the vertical rod 8. At this time, when the bolt 11 at the sleeve body 7 corresponds to the groove 12 at the vertical rod 8, the bolt 11 is rotated into the groove 12, and the second rod body 6, the first rod body 5 and the auxiliary bottom plate 4 can be restricted from moving, ensuring the contact stability between the main bottom plate 2 and the auxiliary bottom plate 4 and the ground. Rubber pads 13 are fixedly connected to the main bottom plate 2 and the two sets of auxiliary bottom plates 4, and the second ring body 16 is fixedly connected to one end and the other end of the two sets of cross bars 3. The hydraulic cylinder 1 A connecting piece 14 is fixedly connected on it, and multiple groups of holes 15 are processed on the connecting piece 14. The holes 15 at the connecting piece 14 are used for external connection components to be installed at the corresponding position of the rotary drilling rig. The outer walls of the two groups of vertical rods 8 are gap-fitted with springs 9. The springs 9 are used to give the second rod 6 a force to pull the first rod 5 and fit the secondary bottom plate 4 with the main bottom plate 2 when the main bottom plate 2, the secondary bottom plate 4 and the second rod 6 are no longer fitted. One end and the other end of the two groups of springs 9 are respectively fixed to the corresponding sleeve 7 and the first ring body 10. The two groups of grooves 12 are placed in the corresponding direction with the corresponding bolts 11, so that the bolts 11 can be inserted into the corresponding grooves 12.

[0024] The working principle of this embodiment is as follows: when in use, the hole 15 at the connection member 14 is installed together with the external connection component and the rotary drilling rig. After installation, with the help of the control and drive components of the rotary drilling rig itself, the hydraulic cylinder 1 can drive the main bottom plate 2 and the two sets of auxiliary bottom plates 4 to contact the ground. When the main bottom plate 2 and the two sets of auxiliary bottom plates 4 are close to the ground, the second rod body 6 will contact the ground in advance. With the help of the main bottom plate 2 and the two sets of auxiliary bottom plates 4 continuously pressing down, the second rod body 6 will pull the first rod body 5 to move the two sets of auxiliary bottom plates 4 , and move horizontally toward one end away from the main bottom plate 2 respectively. Then, when the main bottom plate 2 and the auxiliary bottom plate 4 are in contact with the ground, the contact range of the main bottom plate 2 and the auxiliary bottom plate 4 with the ground will be expanded, which can increase the support stability of the rotary drilling rig. When the main bottom plate 2 and the auxiliary bottom plate 4 are in contact with the ground, the bolts 11 at the sleeve 7 can also be rotated into the grooves 12 of the corresponding vertical rods 8 and placed, and the second rod body 6, the first rod body 5 and the auxiliary bottom plate 4 are restricted in movement to ensure the contact stability of the main bottom plate 2 and the auxiliary bottom plate 4 with the ground.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
