[0033] As Figures 1 to 4 shown, a preferred embodiment of one aspect of the present application provides a cable fixing device 1, which includes a cable height adjustment component, a first fixing component and a second fixing component. The adjustment component has an adjustable thickness; the first fixing component includes a first main body plate 4, at least one first cable buckle 5 and two first limit posts 3. The first main body plate 4 is connected between the two first limit posts 3. The first cable buckle 5 is installed on the edge of the first main body plate 4. Both the first main body plate 4 and the first cable buckle 5 have elasticity.

[0034] The second fixing component includes a second main body plate 7, at least one second cable buckle 6 and two second limit posts 8. The second main body plate 7 is connected between the two second limit posts 8. The second cable buckle 6 is installed on the edge of the second main body plate. Both the second main body plate 7 and the second cable buckle 6 have elasticity.

[0035] The first limit post 3, the second limit post 8 and the cable height adjustment component are detachably connected together. The edge of the first main body plate 4 where the first cable buckle 5 is installed is disposed opposite to the edge of the second main body plate 7 where the second cable buckle 6 is installed, so that the first cable buckle 5 and the second cable buckle 6 are aligned with each other to form a cable fixing ring for sleeving outside the cable to fix the cable.

[0036] Specifically, in this embodiment, the cable height adjustment assembly includes a plurality of standard plates 2. The plurality of standard plates 2 are detachably connected to the first limiting post 3 and the second limiting post 8 layer by layer, and when the plurality of standard plates 2 are selectively connected to the first limiting post 3 and the second limiting post 8, they are used to adjust the thickness of the cable height adjustment assembly.

[0037] Specifically, in this embodiment, the plurality of standard plates 2 are fixed at the bottom of the first limiting post 3 and are used to carry the cable fixing device 1. The number of the standard plates 2 can be increased or decreased according to the height of the high-voltage connector 12 provided on one side, so that the height of the high-voltage cable 11 is aligned with the height of the high-voltage connector 12, to eliminate the stress generated when the high-voltage cable 11 and the corresponding connector are not on the same horizontal plane, and to play a role in protecting the high-voltage connector 12.

[0038] Specifically, in this embodiment, fixing holes 21 are formed in the standard plates 2. The cable height adjustment assembly further includes a first connecting member 9 that is inserted into a fixing target after passing through the fixing holes 21 to fix the standard plates 2 to the fixing target.

[0039] Specifically, in this embodiment, fixing holes 21 are formed in each of the plurality of standard plates 2 and are coaxially arranged, which is convenient for limiting the standard plates 2 relative to the fixing target when the standard plates 2 are increased or decreased. The first connecting member 9 includes, but is not limited to, a plug pin.

[0040] Specifically, in this embodiment, at least one of the first limiting post 3 and the second limiting post 8 is detachably connected to the standard plate 2. The cable fixing device 1 further includes a second connecting member 10 for detachably connecting at least two of the first limiting post 3, the second limiting post 8, and the standard plate 2 to each other.

[0041] Specifically, in this embodiment, a through hole 31 is formed in the first limiting post 3, a connecting hole 81 is formed in the second limiting post 8, and a limiting hole 22 is further formed in the standard plate 2. The through hole 31, the connecting hole 81, and the limiting hole 22 are coaxially arranged; when the cable fixing ring fixes the cable, the second connecting member 10 is inserted into the through hole 31, the connecting hole 81, and the limiting hole 22 to fix the cable.

[0042] Specifically, in this embodiment, the first cable buckle 5 and the second cable buckle 6 are semi-circular, aligned with each other to form a cable fixing ring for sleeving outside the cable to fix the cable. The first cable buckle 5 and the second cable buckle 6 are installed at the edges of the first main board 4 and the second main board 7 along with the placement of the cable; in the initial state, the first cable buckle 5 and the second cable buckle 6 are placed outside the cable fixing device 1; the first main board 4 and the second main board 7 are symmetrically arranged with respect to the cable, and are elastic, having good buffering ability, and can effectively absorb the disturbing force generated by vibration, thereby protecting the corresponding high-voltage connector 12.

[0043] Specifically, in this embodiment, the first cable buckle 5 and the second cable buckle 6 include but are not limited to rubber pads. The elastic coefficient of the first cable buckle 5 is lower than that of the first main board 4, and the coefficient of the second cable buckle 6 is lower than that of the second main board 7. When the cable vibrates, the different deformation amplitudes of the buckle and the main board can avoid resonance, and the larger deformation of the cable buckle is more likely to be damaged. At this time, the damaged cable buckle can be removed from the main board and a new cable buckle can be replaced, so as to avoid replacing the entire cable fixing device 1.

[0044] Specifically, in this embodiment, the first cable buckle 5 is detachably assembled at the edge of the first main board 4, and the second cable buckle 6 is detachably assembled at the edge of the second main board 7. A semi-circular groove is formed at the top of the first main board 4 for installing the first cable buckle 5, and a semi-circular groove is formed at the bottom of the second main board 7 for installing the second cable buckle 6. The first main board 4 and the first limiting post 3 are of an integral structure, and the first main board 4 can be made of rubber or elastic material; the second main board 7 and the second limiting post 8 are of an integral structure, and the second main board 7 can be made of rubber or elastic material, and the first main board and the second main board are made of rigid materials.

One side of the cable fixing device 1 includes a high-voltage connector 12, and the high-voltage connector 12 is also installed on the rotary drilling rig. This device is used to reduce the stress generated by the vibration of the high-voltage cable 11 when the rotary drilling rig is working, so that the high-voltage cable 11 fixed by the high-voltage connector is relatively stable, thereby playing a role in protecting the high-voltage connector 12.

[0048] The specific working process of the above cable fixing device 1 may include the following operations:

[0049] Step 1: Manually sleevethe first cable buckle 5 and the second cable buckle 6 on the high-voltage cable 11.

[0050] Step 2: According to the height of the high-voltage connector 12, adjust the number of standard plates 2 in the cable height adjustment component so that the height of the high-voltage cable 11 is at the same horizontal plane as the height of the cable in the high-voltage connector 12.

[0051] Step 3: The first connecting piece 9 is inserted into the fixing hole 21 opened on the standard plate 2, and a determined number of standard plates 2 are fixed on the rotary drilling rig.

[0052] Step 4: Place the high-voltage cable 11 sleeved with the cable fixing ring in the semi-circular groove opened on the first main body plate 4.

[0053] Step 5: Place the second fixing component above the cable, and the second limiting column 8 abuts against the first limiting column 3.

[0054] Step 6: The second connecting piece 10 is inserted into the through hole 31 opened on the first limiting column 3, the connecting hole 81 opened on the second limiting column 8, and the limiting hole 22 opened on the standard plate 2, and the cable fixing ring is fixed in the fixing ring formed by the alignment of the first main body plate 4 and the second main body plate 7.

[0055] Step 7: The rotary drilling rig starts to work. The first cable buckle 5, the second cable buckle 6, the first main body plate 4 and the second main body plate 7 all have good buffering capabilities, effectively absorbing the disturbing force generated by vibration, and thus protecting the corresponding high-voltage connector 12.

[0056] The cable fixing device 1 and the rotary drilling rig provided by the present utility model can produce multiple beneficial effects compared with the prior art. Specifically:

[0057] 1. In the implementation manner of the present application, the first cable buckle 5 and the second cable buckle 6 are aligned with each other to form a cable fixing ring for fixing the high-voltage cable 11, and have elasticity. The first main body plate 4 and the second main body plate 7 also have elasticity and fix the cable fixing ring, which can effectively absorb the disturbing force generated by the high-voltage cable 11 during the operation of the rotary drilling rig and protect the corresponding high-voltage connector 12.
