Description

Technical Field

[0001] This utility model relates to the field of rotary drilling rig technology, specifically to an electrically driven rotary drilling rig. Background Technology

[0002] Rotary drilling rigs, as a highly efficient pile foundation construction equipment, are widely used in construction, transportation, and other fields. Traditional rotary drilling rigs mostly use diesel engines as their power source, which not only have high energy consumption and serious emissions, but also have the problem of high noise levels, making it difficult to meet current environmental protection construction requirements. Therefore, electrically driven rotary drilling rigs have been developed. However, the battery pack of electric rotary drilling rigs is generally fixed on one side of the drilling platform, requiring additional counterweights to balance the rig. Furthermore, after the battery pack is depleted, it needs to be recharged, resulting in low efficiency.

[0003] Meanwhile, the counterweight structure of existing rotary drilling rigs is mostly fixed, meaning that the weight and position of the counterweight blocks cannot be flexibly adjusted according to working conditions such as drilling depth and drill rod load. This causes the center of gravity of the drilling rig to shift during operation, affecting construction stability and even posing safety hazards.

[0004] Therefore, to address the above problems, an electrically driven rotary drilling rig is proposed. Utility Model Content

The moving mechanism 11 adopts a commonly used tracked walking assembly to adapt to more working conditions. The rotating mechanism 12 is driven by a slewing bearing and a drilling platform 13 is mounted on the rotating mechanism 12 to drive the drilling platform 13 to rotate. A cab 14 is mounted on the drilling platform 13. A lifting assembly 2 and a counterweight adjustment assembly 3 are also mounted on the drilling platform 13, respectively located at both ends of the length of the drilling platform 13 to facilitate the balance of the whole machine. A drill rod assembly 4 is mounted on the lifting assembly 2. The drill rod assembly 4 can be a rotating rod commonly used in rotary drilling rigs. A power supply assembly 5 is mounted on the counterweight adjustment assembly 3 to provide power for the whole machine to work, and the weight of the power supply assembly 5 serves as a counterweight for the balance of the drilling rig. The counterweight adjustment assembly 3 is detachably mounted on the drilling platform 13, and the position of the power supply assembly 5 relative to the drilling platform 13 can be adjusted by the counterweight adjustment assembly 3.

[0041] In an optional embodiment, the lifting assembly 2 includes a lifting arm 21, the bottom end of which is rotatably mounted on one end of the drilling platform 13, and a gooseneck anchor frame 22 is mounted on the top end of the lifting arm 21. Two reversing pulleys 23 are mounted on the gooseneck anchor frame 22. The lifting arm 21 is rotatably connected to a lifting power component 24, which is a hydraulic cylinder or an electric actuator, and is rotatably mounted on the drilling platform 13 to drive the lifting arm 21 to rotate around the drilling platform 13. The lifting arm 21 is also equipped with a winch 25 and a main boom pulley 26. The winch 25 has its own power component, and a wire rope 27 is wound on the winch 25. One end of the wire rope 27 is successively placed on the main boom pulley 26 and the reversing pulley 23 and then connected to the drill rod assembly 4 to control the lifting and lowering movement of the drill rod assembly 4.

[0042] In an optional embodiment, the counterweight adjustment assembly 3 includes a fixed base frame 31, which is bolted to the drilling platform 13. A movable frame 32 is slidably mounted on the fixed base frame 31. The sliding direction of the movable frame 32 is parallel to the length direction of the drilling platform 13. The fixed base frame 31 and the movable frame 32 are connected by a translation component 6, which drives the movable frame 32 to slide on the fixed base frame 31. The movable frame 32 is connected to the counterweight moving frame 33 by a quick-connect component 7. An additional frame 34 is detachably mounted on the upper end of the counterweight moving frame 33. Several additional frames 34 are detachably stacked on the counterweight moving frame 33 to increase the counterweight. A power supply component 5 is mounted on both the counterweight moving frame 33 and the additional frame 34.

[0043] In an optional embodiment, the power supply component 5 adopts a modular battery pack, which connects the electrical system, moving mechanism 11, and rotating mechanism 12 of the whole machine. The electrical system adopts the electrical system commonly used in rotary drilling rigs on the market. The endurance of the whole machine can be adjusted by freely adding or removing battery packs, and the endurance can be quickly replenished by replacing battery packs. The battery pack that needs to be charged can be removed and replaced with a fully charged battery pack to avoid the construction time wasted on charging the equipment and improve construction efficiency.

[0044] In an optional embodiment, a support component 8 is provided at the bottom of the movable frame 32 at the end away from the lifting component 2. This component supports the ground when the movable frame 32 is extended, enhancing the stability of the drilling rig. The support component 8 includes a support telescopic member 81, which is a hydraulic outrigger, and at least two of them are provided. The support telescopic member 81 is provided at the bottom of the movable frame 32 via a support seat 82. The support seat 82 is connected to the output end of the indexing power component 83 via a rotating shaft. The indexing power component 83 is a motor, which is provided on the movable frame 32. The indexing power component 83 drives the support seat 82 to rotate, which can adjust the position of the support telescopic member 81 to be horizontal or vertical. When support is needed, it is set to a vertical state for support, and when support is not needed, it is set to a horizontal state and stored under the drilling rig platform 13 to avoid interference with the movement mechanism 11 when the drilling rig platform 13 rotates. Preferably, the bottom end of the support telescopic member 81 is provided with casters, so that it can move while providing support, which improves its practicality.

[0045] In an optional embodiment, the quick-connect assembly 7 is configured as a Jameson coupler, i.e., a Jameson coupler used for connecting traditional train carriages, including a hook head 71, a hook tongue 72, and a locking pin 73.

The locking pin 73 slides through the hook head 71, and the hook tongue 72 and locking pin 73 can engage, thereby achieving a quick connection between the movable frame 32 and the counterweight moving frame 33 and ensuring the stability of the connection. A disconnection power component 74 is provided on the movable frame 32. 74 uses a small electric actuator. The output end of the disconnecting power component 74 is connected to the top of the locking pin 73 on the hook 71 of the movable frame 32 via a flexible chain 75. This is used to pull out the locking pin 73 to disconnect it from the hook tongue 72. At this time, the movable frame 32 can be easily removed from the counterweight moving frame 33. Then, the output end of the disconnecting power component 74 is retracted. The locking pin 73 does not move at this time, and the flexible chain 75 is in a flexible state. When the movable frame 32 is reconnected to the counterweight moving frame 33, the locking pin 73 falls naturally due to gravity, causing the flexible chain 75 to return to a stretched state.

The translation force component 63 is a motor, which is arranged on the movable frame 32. The translation force component 63 drives the gears 62 to rotate, thereby causing the movable frame 32 to slide along the length direction of the racks 61, thereby adjusting the position of the counterweight.

[0047] In an optional embodiment, the counterweight moving frame 33 includes a bottom support plate 331, a side support plate 332, and a limiting support plate 333.

[0053] Working principle: The operator controls the moving mechanism 11 from inside the cab 14 to move the drilling rig to the construction position; the rotation mechanism 12 adjusts the direction of the drilling platform 13 so that the drill rod assembly 4 is aligned with the drilling position; the operator controls the indexing power component 83 of the support assembly 8 to drive the support seat 82 to rotate to the appropriate direction, and then controls the extension component 81 of the support to extend until the bottom end of the extension component 81 contacts the ground and tightens, enhancing the stability of the drilling rig; the counterweight is adjusted according to the drilling depth and the load on the drill rod. Counterweight position adjustment: the translating power component 63 is activated, driving the gear 62. Rotating along the rack 61 causes the movable frame 32 to slide along the fixed base frame 31, thereby adjusting the position of the power supply assembly 5 relative to the drilling platform 13 until the drilling rig's center of gravity is balanced; Counterweight adjustment: If it is necessary to add counterweight, insert the forklift forks into the fork slot 35, move the additional frame 34 above the counterweight moving frame 33, and lock the additional frame 34. Place an additional battery pack in the positioning slot of the additional frame 34; If it is necessary to reduce counterweight, push the sliding plate 97 to move laterally.
