Description

Technical Field

[0001] This utility model relates to the field of coal mine drilling rig technology, specifically to an all-around rotary hoisting device for drilling rigs. Background Technology

[0002] Traditional drilling rigs primarily adjust their orientation and angle through linkage mechanisms, using the extension and retraction of hydraulic cylinders and the rotation of hinge points. This adjustment method relies on the displacement of the hydraulic cylinders and the size of the equipment, often failing to achieve omnidirectional, blind-angle-free angle adjustment. Furthermore, its stability requires the combined effect of the hydraulic cylinders' self-locking capability and mechanical clamping devices. Especially when the drilling rig is under heavy operating load, the angle adjustment process is often slow and stability cannot be guaranteed. Moreover, due to the large overall size of the drilling rig and its vehicle body, it is inconvenient to rotate when operating in confined spaces or complex terrain, reducing the efficiency and flexibility of drilling operations. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an all-around rotary lifting device for drilling rigs, which can adjust the height and angle of the drilling rig's working mechanism in all directions, making the drilling rig more adaptable and the drilling more flexible.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an all-around rotary lifting device for drilling rigs, including a rotary mechanism, a mounting plate located above the rotary mechanism, and a lifting mechanism set on the mounting plate. The rotary mechanism includes a first cycloidal motor and a rotary reducer that is drivenly connected to the first cycloidal motor. The output end of the rotary reducer is connected to the bottom of the mounting plate. The lifting mechanism includes a lifting frame and a lifting cylinder for driving the lifting frame to move in the vertical direction. A drilling rig working mechanism is installed on the lifting frame. An angle adjustment mechanism for adjusting the angle between the drilling rig working mechanism and the horizontal plane is provided on the lifting frame.

[0005] The working principle of this scheme is as follows: The drill rod is installed on the drilling rig's working mechanism. When it is necessary to adjust the drill rod's horizontal position according to the drilling conditions, the first cycloidal motor is driven to rotate by high-pressure oil. The rotation of the first cycloidal motor drives the rotary reducer to rotate, and the rotation of the rotary reducer drives the mounting plate to rotate, thereby driving the drilling rig's working mechanism and the drill rod to rotate. When it is necessary to adjust the height of the drill rod, the lifting cylinder drives the lifting frame to move vertically, thereby driving the drilling rig's working mechanism and the drill rod to move vertically. When it is necessary to adjust the angle between the drill rod and the horizontal plane, the angle adjustment mechanism drives the drilling rig's working mechanism to rotate along the longitudinal plane, thereby adjusting the angle between the drill rod and the horizontal plane.

[0006] Compared with existing technologies, the advantages of this solution are as follows: When the drilling rig is in a relatively confined space but needs to adjust the position of the drill rod according to the drilling conditions, the overall size of the drilling rig is large, making it difficult to rotate in a confined environment. By setting a slewing mechanism to drive the working mechanism of the drilling rig to rotate, thereby driving the drill rod to rotate, the rotation is more flexible, thus making the drilling rig more adaptable. When it is necessary to adjust the height of the drill rod according to the specific drilling environment, the lifting mechanism drives the working mechanism of the drilling rig to move vertically. After adjusting the working mechanism of the drilling rig to a suitable height, space is left for the swing of the working mechanism of the drilling rig when adjusting the angle, thereby realizing all-round angle adjustment.

[0007] In a preferred embodiment of this utility model, there are two lifting frames, which are located between the two lifting frames along the width direction of the drilling rig working mechanism. The angle adjustment mechanism is located inside one of the lifting frames.

[0008] The beneficial effects of this solution are as follows: Compared with setting a lifting frame on one side of the drilling rig working mechanism, setting lifting frames on both sides of the drilling rig working mechanism not only makes the vertical movement of the drilling rig working mechanism more stable, but also the lifting frames on both sides of the drilling rig working mechanism play a supporting and connecting role.

[0009] In a preferred embodiment of the present invention, the angle adjustment mechanism includes a second cycloidal motor and a screw worm gear reducer that is driven by the second cycloidal motor. The output end of the screw worm gear reducer is connected to one side of the drilling rig's working mechanism.

[0010] The beneficial effects of this solution are: by using a lead screw worm gear reducer, the second cycloidal motor drives the lead screw to rotate, the lead screw rotates and drives the worm gear to rotate, thereby driving the drilling rig working mechanism to rotate, so as to achieve rapid adjustment and locking of the drilling rig working mechanism angle.

[0011] In a preferred embodiment of this utility model, guide posts are provided around the upper side of the mounting plate, and sleeves for sliding cooperation with the guide posts are provided on both sides of each lifting frame.

[0012] The beneficial effects of this solution are as follows: the lifting frame slides with the guide column through the sleeve. The guide column guides the movement of the lifting frame in the vertical direction and also limits the horizontal movement of the lifting frame. When the mounting plate is rotated by the rotary mechanism, the lifting frame rotates accordingly. The stability of the lifting frame during rotation is ensured by the cooperation between the lifting frame and the guide column.

[0013] In a preferred embodiment of this utility model, the drilling rig working mechanism is located on the central axis of the rotary reducer.

[0014] The beneficial effects of this solution are: setting the drilling rig's working mechanism on the central axis of the rotary reducer can reduce the eccentric force on the rotary reducer and help extend its service life.

[0015] In a preferred embodiment of this utility model, the lifting cylinders are respectively mounted on two sleeves located on the rear side of the lifting frame, and the lower end of the lifting cylinders is fixedly connected to the mounting plate.

[0016] Explanation: The drilling rig's working mechanism is usually located at the front of the drilling rig body.

[0017] The beneficial effects of this solution are as follows: Since the drilling rig's working mechanism is located at the front end of the drilling rig body, the lifting cylinder is placed on two sleeves located at the rear of the lifting frame. This arrangement places the force on the drilling rig body itself, which greatly improves the stability of the drilling rig during operation. Attached Figure Description

[0026] As attached Figure 1 and attached Figure 2 As shown: The mounting plate 2 is also provided with a lifting mechanism, which includes a lifting frame 3 and a lifting cylinder 4 for driving the lifting frame 3 to move in the vertical direction. The lifting frame 3 is equipped with a drilling rig working mechanism 6. Specifically, there are two lifting frames 3. Along the width direction of the drilling rig working mechanism 6, the drilling rig working mechanism 6 is located between the two lifting frames 3. The drilling rig working mechanism 6 is located on the central axis of the rotary reducer 702. Each lifting frame 3 has a sleeve 301 on both sides for sliding cooperation with the guide column 5. The lifting cylinder 4 is respectively set on the two sleeves 301 located on the rear side of the lifting frame 3.

[0027] The lifting frame 3 is provided with an angle adjustment mechanism 8 for adjusting the angle between the drilling rig working mechanism 6 and the horizontal plane.

In this embodiment, the first cycloidal motor 701, the second cycloidal motor 801 and the lifting cylinder 4 are all driven by high-pressure oil.

[0028] Specific slewing and lifting process:

[0029] In the initial state, the lifting frame 3 is mounted on the guide column 5. When it is necessary to adjust the horizontal position of the drilling rig working mechanism 6 according to the drilling situation, the first cycloidal motor 701 drives the rotary reducer 702 to rotate, and the rotary reducer 702 drives the mounting plate 2 to rotate, thereby driving the lifting frame 3 and the drilling rig working mechanism 6 to rotate. When it is necessary to adjust the height of the drilling rig working mechanism 6, the lifting cylinder 4 drives the lifting frame 3 to move up and down along the guide column 5, thereby driving the drilling rig working mechanism 6 to move up and down along the guide column 5. When it is necessary to adjust the angle between the drilling rig working mechanism 6 and the horizontal plane, the second cycloidal motor 801 drives the lead screw 802 to rotate, and the lead screw 802 drives the worm gear 803 to rotate, thereby driving the drilling rig working mechanism 6 to rotate along the longitudinal plane, thus realizing the rapid adjustment and locking of the angle of the drilling rig working mechanism 6.
