Fig. 2 is a schematic view of a partial structure of the rotary drilling rig 100 according to the embodiment; fig. 3 is a schematic view of a partial structure of the rotary drilling rig 100 according to the present embodiment. Referring to fig. 1 and 2, in the present embodiment, the lubricating element is a lubricating oil can 121, the lubricating oil can 121 is provided with an oil outlet portion (not shown), and the suspension cable can be connected to the drilling assembly 141 after passing through the oil outlet portion. The steel wire rope 119 is lubricated by the lubricating oil can 121 in the process of lifting or lowering the drill rod 133, so that the technical problem that the steel wire rope 119 cannot be lubricated from the elevator 131 to the winch when the elevator 131 reaches the uppermost limit position can be effectively solved, the steel wire rope 119 is effectively prevented from being damaged, and the service life of the steel wire rope 119 is prolonged.
In detail, in the present embodiment, the lubricating oil can 121 is in a hollow circular truncated cone shape, and the diameter of the end of the lubricating oil can 121 close to the drilling assembly 141 is smaller than the diameter of the end close to the pulley frame assembly 113. The shape of the lubricating oil pot 121 is designed to be similar to a funnel shape, so that when the elevator 131 reaches the uppermost limit position, the lubricating oil can automatically and continuously flow to the steel wire rope 119 under the action of the gravity of the lubricating oil, and the last drop of the lubricating oil is ensured to act on the steel wire rope 119, so that the lubricating resource is effectively saved. Of course, in other embodiments of the present invention, the shape of the lubricating oil can 121 may also be selected according to the requirement, for example, it may be selected as a cube, a cuboid or a special shape.

In detail, in the present embodiment, a first end of the hanging rod 123 is hung on the pulley frame assembly 113 and can rotate around the pulley frame assembly 113, and the lubricating member is hung on a second end of the hanging rod 123 and can rotate around the second end of the hanging rod 123. The lubricating oil can 121 is fixed by the hanging rod 123, so that the lubricating oil can 121 can rotate around the connecting point back and forth. Therefore, after the steel wire rope 119 passes through the lubricating oil pot 121 from the pulley 145 and is fixed on the elevator 131, the lubricating oil pot 121 is filled with lubricating grease, the lubricating grease can drive the steel wire rope 119 to shuttle in the oil pot along with the lifting and lowering of the drill rod 133, the grease can be uniformly coated on the surface of the steel wire rope 119, the lubricating effect is further improved, and the lubricating effect is guaranteed. Of course, in the utility model discloses in other embodiments, lubricating oil can 121 also can be through directly setting up in the wire rope 119 outside or set up in mast 111 etc. the embodiment of the utility model is no longer repeated.
Preferably, the rotary drilling rig 100 further comprises a first lock pin 125 and a second lock pin 127. The first locking pin 125 is disposed between the first end of the hanging rod 123 and the pulley frame assembly 113, and is used for relatively locking the hanging rod 123 and the pulley frame assembly 113, and the second locking pin 127 is disposed between the second end of the hanging rod 123 and the lubricating member, and is used for relatively locking the lubricating member and the hanging rod 123, so that the lubricating oil can 121 can be kept at a specific position when not used or required for operation, thereby improving the practical value of the lubricating oil can 121.
Further preferably, nylon sleeves 129 are arranged at two ends of the lubricating piece, and the nylon sleeves 129 are sleeved outside the suspension ropes. The contact surface of the lubricating oil can 121 and the steel wire rope 119 is made of a material with a low friction coefficient such as nylon, so that friction between the steel wire rope 119 and a can opening of the lubricating oil can 121 is reduced, and the service lives of the lubricating oil can 121 and the steel wire rope 119 are further prolonged.
Furthermore, the material of the lubricant may be selected to be a low friction material, such as a polyurethane material, and the wear of the steel cable 119 may be further reduced by the low friction material, so as to further prolong the service life.
The following explains the working principle of the rotary drilling rig 100 provided by the embodiment of the present invention in detail:
when the digging and drilling operation is performed, a driver can control the rotary digging and drilling machine 100 to be adjusted to a working state, then drive the drilling tool 135 to be lowered into a hole to be dug through the power head 137, and then drive the drilling rod 133 to drive the drilling tool 135 to perform the digging and drilling operation. After the excavation operation is completed, the drill rod 133 and the drilling tool 135 may be lifted up by hoisting the wire rope 119 by the hoist 117, thereby taking the drill rod 133 and the drilling tool 135 out.
In the above process, the lubricating oil pot 121 is arranged so that the suspension cable such as the steel wire rope 119 can be effectively lubricated in the upper body and lowering process of the drill rod 133, and particularly when the elevator 131 reaches the uppermost limit position, the lubricating oil pot 121 can be suitable for conveying grease to the steel wire rope 119, so that the service life of the suspension cable can be effectively prolonged, the operation quality is improved, and the construction cost is reduced.
In summary, the above is provided. The embodiment of the utility model provides a dig rig 100 soon, its suspension cable can be lubricated effectively all the time to can improve the life-span of hanging the hoist cable effectively, improve the operating quality, reduce construction cost.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
