[0002] A drilling rig is a machine that drives and controls a drill string to drill and can lift and lower the drill string. It is mainly used to drill holes deep into the earth's crust, take rock cores, or open channels for the exploitation of oil, natural gas, and groundwater (cold water and hot water) resources. The structure of a drilling rig mainly includes components such as a rotary table, a feed system, a hoisting system, an engine, and a transmission system. The working principle of a rotary drilling rig is to drill by rotating the drill bit.

[0003] During the process of geological exploration, it is often necessary to use a drilling rig for drilling operations. However, traditional drilling rigs can only drill at a fixed angle during construction and do not have the function of 360-degree rotation.

[0023] As Figures 1 - 5 shown, for the 360° rotation mechanism of the drilling rig provided in this embodiment, a downward sliding fixed plate 11 is fixedly connected to one side wall of the downward sliding fixed frame 1. Downward sliding convex strips 12 are fixedly connected to both side walls of the downward sliding fixed plate 11. There are two first pressing plates 2 on the side of the downward sliding convex strip 12 away from the downward sliding fixed plate 11. The first pressing plate 2 is in a right-angled shape. A first connecting block 21 is fixedly connected to the inner wall of one side of the first pressing plate 2, and a second connecting block 22 is fixedly connected to the inner wall of the other side of the first pressing plate 2. The side of the first connecting block 21 away from the first pressing plate 2 is in contact with the side of the downward sliding convex strip 12 close to the downward sliding fixed frame 1, and the side of the second connecting block 22 away from the first pressing plate 2 is in contact with the side of the downward sliding convex strip 12 away from the downward sliding fixed plate 11. The downward sliding fixed frame 1 is used to support and fix this rotation mechanism, and the downward sliding fixed plate 11 and the downward sliding convex strip 12 are used to connect the first pressing plate 2 and support the intermediate sliding frame bottom plate 3.

[0024] Secondly, as Figure 1 and Figure 4 shown, a common fixed connection of the four first pressing plates 2 away from the downward sliding fixed frame 1 is the intermediate sliding frame bottom plate 3. The first pressing plates 2 are located at the four corner positions of the intermediate sliding frame bottom plate 3. A intermediate sliding frame support member 31 is fixedly connected to the side of the intermediate sliding frame bottom plate 3 away from the first pressing plate 2. A intermediate sliding frame top plate 4 is fixedly connected to the side of the intermediate sliding frame support member 31 away from the intermediate sliding frame bottom plate 3. A intermediate sliding frame convex block 41 is fixedly connected to the side of the intermediate sliding frame top plate 4 away from the intermediate sliding frame support member 31. A hydraulic slewing bearing 5 is fixedly connected to the side wall of the intermediate sliding frame convex block 41 away from the intermediate sliding frame top plate 4 through bolts. An upward sliding fixed frame 6 is fixedly connected to the side of the hydraulic slewing bearing 5 away from the intermediate sliding frame convex block 41 through bolts. An upward sliding fixed plate 61 is fixedly connected to the side of the upward sliding fixed frame 6 away from the hydraulic slewing bearing 5. The first pressing plate 2 is used to connect the intermediate sliding frame bottom plate 3 and the downward sliding convex strip 12. The intermediate sliding frame convex block 41 is used to increase the bearing capacity of the intermediate sliding frame top plate 4. The hydraulic slewing bearing 5 is used to drive the upward sliding fixed frame 6 to rotate.

[0025] Furthermore, as Figure 1 and Figure 5As shown in the figure, four second pressing plates 7 are fixedly connected to the side of the upper sliding fixing plate 61 away from the upper sliding fixing frame 6. The four second pressing plates 7 are located at the four corner positions of the upper sliding fixing plate 61. The second pressing plate 7 is in a right-angled shape. A third connecting block 71 is fixedly connected to the inner wall of one side of the second pressing plate 7, and a fourth connecting block 72 is fixedly connected to the inner wall of the other side of the second pressing plate 7. The second pressing plate 7, the third connecting block 71 and the fourth connecting block 72 are used to install the mast fixing strip 81.

[0026] Furthermore, as Figure 1 and Figure 5 shown, a mast 8 is provided on the side of the upper sliding fixing plate 61 away from the upper sliding fixing frame 6. Two mast fixing strips 81 are fixedly connected to the side wall of the mast 8 close to the upper sliding fixing plate 61. The two mast fixing strips 81 are symmetrically distributed about the central axis of the mast 8. The side of the third connecting block 71 away from the second pressing plate 7 is in contact with the side of the corresponding mast fixing strip 81 close to the mast 8, and the side of the fourth connecting block 72 away from the second pressing plate 7 is in contact with the outside of the corresponding mast fixing strip 81. The mast fixing strip 81 is used to install the mast 8, and the mast 8 is used to install the slewer 9.

[0027] Even further, as Figure 1 shown, a slewer 9 is fixedly installed on the side of the mast 8 away from the mast fixing strip 81. The slewer 9 is used for power transmission to the special drill bit.

[0028] As Figures 1 - 5 shown, the principle of the 360° rotation mechanism for the drilling rig construction provided in this embodiment is as follows: When using this rotation mechanism, this rotation mechanism will be fixedly installed through the lower sliding fixing frame 1. Use four first pressing plates 2, the first connecting block 21 and the second connecting block 22 to install the intermediate sliding frame bottom plate 3 onto the lower sliding fixing plate 11 and the lower sliding convex strip 12. Use four second pressing plates 7, the third connecting block 71 and the fourth connecting block 72 to install the mast fixing strip 81 and the mast 8 onto the upper sliding fixing plate 61. Install the slewer 9 onto the mast 8. Control the oil circuit to enter the hydraulic slewing bearing 5 by manipulating the control element, so that the hydraulic slewing bearing 5 drives the upper sliding fixing frame 6 and the upper sliding fixing plate 61 to rotate. The upper sliding fixing plate 61 cooperates with the second pressing plate 7 to drive the mast fixing strip 81 and the mast 8 to rotate. The mast 8 drives the slewer 9 to rotate, and during the drilling rig construction, 360-degree rotation of the drilling rig is achieved.
