Description

Technical Field

[0001] This invention relates to an auxiliary device for unloading rotary drilling rigs and a rotary drilling rig, belonging to the field of engineering machinery technology. Background Technology

[0002] During rotary drilling rig construction, the slewing of the upper structure is a frequently used action. The rotary drilling rig turntable mainly consists of a slewing reducer, a slewing bearing, the turntable body, and a drill mast support. Its function is to support the weight of the upper structure and enable its rotational movement. The rotational movement of the turntable is driven by a hydraulic pump supplying oil to a hydraulic motor, which in turn drives the internal gear ring of the slewing bearing via the pinion gear of the slewing reducer, thus causing the upper structure to rotate. The main purpose of the upper structure's slewing is to unload soil after completing a borehole. Frequent slewing for unloading significantly reduces the operating efficiency of the rotary drilling rig, making it difficult to accurately position the borehole after unloading. Furthermore, if the upper structure's slewing mechanism malfunctions, it can cause the entire construction to be suspended, resulting in serious losses for the entire project. Summary of the Invention

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0020] Example 1:

[0021] like Figure 1 As shown, this embodiment of the invention provides a rotary drilling rig unloading auxiliary device, including a rotary drilling rig body 1, a rotary mechanism 2 set at the bottom of the rotary drilling rig body 1, a mechanical arm 3 set at the movable end of the rotary mechanism 2, and a hopper 4 set at the end of the mechanical arm 3. When the rotary drilling rig body 1 completes one rotation to load soil and lifts the drill bit to the ground for unloading, the rotary mechanism 2 and the mechanical arm 3 adjust the hopper 4 to the bottom of the drill bit to receive the soil and complete the unloading. After the unloading is completed, the hopper 4 is reset, and then the rotary drilling rig body 1 can directly lower the drill bit to continue drilling operations. In this process, the rotary drilling rig body 1 is exempt from rotating and unloading soil, which improves work efficiency and the safety and stability of the operation.

[0022] like Figure 2 As shown, the rotary mechanism 2 in this embodiment includes a housing 21, a worm gear 22 horizontally disposed in the middle of the housing 21, a worm gear shaft 23 vertically passing through the middle of the worm gear 22, support bearings 24 disposed on both sides of the worm gear 22 and sleeved on the worm gear shaft 23, a worm 25 disposed on one side of the worm gear 22 and meshing with the worm gear 22, and a reduction motor connected to the worm 25. The outer ring of the support bearings 24 is fixedly connected to the inside of the housing 21, and the bottom of the worm gear shaft 23 extends to the outside of the housing 21 and is connected to the robotic arm 3. During operation, the reduction motor drives the worm 25 to rotate, the worm 25 drives the worm gear 22 to rotate, the worm gear 22 drives the worm gear shaft 23 to rotate, and the rotation of the worm gear shaft 23 drives the robotic arm 3 to rotate, thereby adjusting the position of the hopper 4. In order to support the weight of the robotic arm 3 and the hopper 4, the worm gear shaft 23 is fixed by two support bearings 24 to ensure its stable operation.

[0023] like Figure 3-4As shown, the robotic arm 3 includes a first telescopic arm 31, a support beam 32 disposed at the movable end of the first telescopic arm 31, and adjusting arms 33 disposed at both ends of the support beam 32. Each adjusting arm 33 includes a first support rod 331 and a second support rod 332 connected by ball joints. The end of the first support rod 331 is fixedly connected to the support beam 32, and the end of the second support rod 332 is hinged to the hopper 4. A second telescopic arm 333 and a third telescopic arm 334 are respectively disposed on the upper and outer sides of the adjusting arm 33. The movable and fixed ends of the second telescopic arm 333 and the third telescopic arm 334 are respectively hinged to the second support rod 332 and the first support rod 331. The design of the double adjusting arms 33 stabilizes the hopper 4. When the second telescopic arm 333 extends or retracts, the first support rod 331 can move up and down, thereby adjusting the height of the hopper 4. When the third telescopic arm 334 extends or retracts, the first support rod 331 can move left and right, thereby adjusting the orientation of the hopper 4.

[0024] To facilitate the unloading of soil from hopper 4, a fourth telescopic arm 335 is installed on the lower side of the second support rod 332. The movable and fixed ends of the fourth telescopic arm 335 are hinged to hopper 4 and the second support rod 332, respectively. When the fourth telescopic arm 335 extends or retracts, hopper 4 can rotate outward along the end of the second support rod 331, thereby unloading soil. The first, second, third, and fourth telescopic rods can be selected using hydraulic cylinders or electric push rods according to actual needs.

[0025] In this embodiment, the position and posture of the hopper 4 can be flexibly adjusted through the rotary mechanism 2 and the robotic arm 3, thereby assisting in unloading soil from the rotary drilling rig, ensuring the stable operation of the rotary drilling rig and improving its work efficiency.

[0026] Example 2:

[0027] The present invention provides a rotary drilling rig, which includes the above-mentioned unloading auxiliary device, including a rotary drilling rig body 1, a rotary mechanism 2 set at the bottom of the rotary drilling rig body 1, a mechanical arm 3 set at the movable end of the rotary mechanism 2, and a hopper 4 set at the end of the mechanical arm 3; when the rotary drilling rig body 1 completes one rotation to load soil and lifts the drill bit to the ground to unload soil, the rotary mechanism 2 and the mechanical arm 3 adjust the hopper 4 to the bottom of the drill bit to receive the soil and complete the unloading.

[0028] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
