Technical Field

The invention relates to the technical field of engineering machinery, in particular to a hydraulic system of a drilling machine.

Background

In a hydraulic system of a construction machine, a single power source is often used to drive a hydraulic pump of the hydraulic system for supplying oil to each actuator, and for example, only an engine is used as power to drive the hydraulic pump, or only an electric motor is used as power to drive the hydraulic pump. However, the instantaneous power that the engine can provide is less, and sometimes it is difficult to accomplish the work condition that the instantaneous power consumption is great to utilize the engine as power, and the motor can improve higher instantaneous power, however, when needing to transition to engineering machinery, the cable that needs to connect the power is longer, and the transition process is loaded down with trivial details.

The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

The embodiment of the invention discloses a hydraulic system of a drilling machine, which also comprises a mechanical structure part, wherein the mechanical structure part comprises a frame, a mechanical arm and the like, the mechanical arm is arranged on the frame and used for enabling a drill bit to carry out posture adjustment, the mechanical arm is driven to rotate and swing so as to change the orientation of the drill bit to drill holes with different spatial postures, and the drill bit is enabled to realize drilling operation by feeding the drill bit.

As shown in fig. 1, the present invention provides a hydraulic system of a drilling machine, comprising: the hydraulic power mechanism comprises a hydraulic actuating mechanism 10, a hydraulic traveling mechanism 20, a first hydraulic power mechanism 30 and a second hydraulic power mechanism 40.

The hydraulic actuator 10 comprises a corner hydraulic motor 13 and a telescopic oil cylinder 11 for rotating and swinging the mechanical arm of the drilling machine, and further comprises a supporting leg oil cylinder 12, a hydraulic vibration cylinder 14 and the like, wherein the hydraulic actuator 10 is used for adjusting the rotation and the swinging of the mechanical arm and providing vibration for a drill bit after supporting the drilling machine, so that the drilling machine can perform drilling operation. For example, the hydraulic motor 13 can be used for driving the mechanical arm to rotate by using the corner, the telescopic oil cylinder 11 can be used for adjusting the swing of the mechanical arm or driving the drill bit to feed, and the hydraulic vibration cylinder 14 can also be used for providing vibration for the drill bit.

The hydraulic traveling mechanism 20 is used for driving the drilling machine to travel, the drilling machine traveling can be used for changing the position of the drilling machine so as to carry out drilling operation at a new position, and the drilling machine traveling is also used for equipment transfer.

The hydraulic traveling mechanism 20 includes traveling hydraulic motors 21 located on both sides of the frame and traveling wheels mounted on the traveling hydraulic motors 21.

The first hydraulic power mechanism 30 comprises an engine 31 and a first hydraulic pump group 32 connected with the engine 31, the engine 31 is used for driving the first hydraulic pump group 32 to operate, and the first hydraulic pump group 32 is connected with the hydraulic traveling mechanism 20 and the hydraulic actuating mechanism 10 for supplying oil to the hydraulic traveling mechanism 20 and the hydraulic actuating mechanism 10.

The second hydraulic power mechanism 40 includes an electric motor 41 and a second hydraulic pump group 42 connected to the electric motor 41, the electric motor 41 is used for driving the second hydraulic pump group 42 to operate, and the second hydraulic pump group 42 is connected to the hydraulic actuator 10 and the hydraulic traveling mechanism 20 for supplying oil to the hydraulic actuator 10 and the hydraulic traveling mechanism 20. The second hydraulic power mechanism 40 includes two sets.

When the drilling machine needs to drill holes or insert pipes in the surrounding environment, the second hydraulic power mechanism 40 can be operated independently, namely, the motor 41 drives the second hydraulic pump group 42 to operate, and the instantaneous power provided by the motor 41 is large, so that the construction operation requirement can be met. Of course, the hydraulic oil may be supplementarily supplied to increase the operation power of the hydraulic actuator 10 by simultaneously operating the first hydraulic power mechanism 30.

The hydraulic pump set and each actuator utilize a reversing valve to switch oil paths, for example, in a main pipeline of the system, the electromagnetic reversing valve 51 is arranged to realize the switching of the oil paths, and in a branch pipeline, a manual reversing valve 52 can be utilized to drive the support leg oil cylinder 12 and the telescopic oil cylinder 11 to act.

When the drilling machine needs to be transferred, the first hydraulic power mechanism 30 can be operated independently, that is, the engine 31 drives the first hydraulic pump group 32 to operate, so that the resetting of each mechanical arm and the driving of the hydraulic traveling mechanism 20 are completed. In this way, the cable for supplying power to the motor 41 can be removed in advance without being driven by the motor 41.

The turning hydraulic system provided by the invention has the advantages that:

the engine 31 and the motor 41 are used for providing power for the hydraulic pump set, and one of the engine and the motor is selected as a power source in a selective manner, so that the drilling machine can meet the construction requirements and is convenient to transition.
