Description

Technical Field

[0001] This utility model belongs to the field of down-the-hole drilling rig technology, specifically relating to a 360° rotatable reverse circulation swing frame mechanism. Background Technology

[0002] Reverse circulation drilling rigs are drilling machines that use a pump-suction and slag-discharge method. Their working principle involves using the high-frequency vibration and cutting force of the drill bit to break up and transport soil and rock to the surface. In operation, the drill bit vibrates and rotates under the drive of the drive unit, cutting and breaking up the soil and rock. Simultaneously, the circulation system transports the cut soil and rock back to the surface via high-pressure water or air. This method of rock powder sampling can compensate for deficiencies in core sampling and more accurately determine the ore grade at that location.

[0003] When installing and positioning the rock powder sampling and collection filter device in the air-lift reverse circulation drilling rig, a reverse circulation swing frame mechanism is required. However, the existing reverse circulation swing frame mechanism does not have a wide range of multi-angle adjustment function, making it difficult to ensure that the rock powder sampling and collection filter device is always properly perpendicular to the ground, which reduces the collection efficiency and safety, and is not conducive to the sampling and collection of rock powder under various terrain conditions.

[0037] See appendix Figure 1-2 As shown, this utility model embodiment provides a 360° rotatable reverse circulation swing frame mechanism, including a base 100 mounted on an air-lift reverse circulation drilling rig, a mounting base 200 for providing an installation foundation for a rock powder sampling, collection, and filtration device, a swaying component 300 for driving the mounting base 200 to swing within a 90° range, a pitching component 400 for driving the mounting base 200 to pitch within a 30° range, a compensation propulsion component 500 for driving the mounting base 200 to move within a 300mm range, and a rotation component 600 for driving the mounting base 200 to rotate 360°. The swaying component 300, pitching component 400, compensation propulsion component 500, and rotation component 600 are sequentially arranged between the base 100 and the mounting base 200.

[0038] See Figure 3As shown, in order to realize the position switching of the rock powder sampling and collection filtration device in the transportation state and the working state, the oscillation component 300 includes an oscillation seat 310 rotatably connected to the base 100 away from the air-lift reverse circulation drilling machine by a pin. The oscillation seat 310 and the base 100 are rotatably connected by a first hydraulic cylinder 320 by a pin. The pitch component 400 is set on the oscillation seat 310. By activating the first hydraulic cylinder 320, the output end of the first hydraulic cylinder 320 can drive the oscillation seat 310, the pitch component 400, the compensation propulsion component 500, the rotation component 600 and the mounting base 200 to swing within a 90° range around the pin between the oscillation seat 310 and the base 100.

[0039] See Figure 4-5 As shown, in order to achieve the pitch angle positioning of the rock powder sampling and collection filtration device, the pitch component 400 includes a bracket 410 rotatably connected to the side of the sway seat 310 away from the base 100 via a pin. A second hydraulic cylinder 420 is rotatably connected between the bracket 410 and the sway seat 310 via a pin. A compensation propulsion component 500 is mounted on the bracket 410. By activating the second hydraulic cylinder 420, the output end of the second hydraulic cylinder 420 can drive the bracket 410, the compensation propulsion component 500, the rotation component 600, and the mounting base 200 to pitch within a 30° range around the pin between the bracket 410 and the sway seat 310.

[0040] See Figure 5-7 As shown, in order to achieve the height positioning of the rock powder sampling and collection filtration device, the compensation propulsion component 500 includes a slide plate 510 slidably connected to the side of the bracket 410 away from the sway seat 310. A connecting plate 520 is fixedly connected to the lower part of the slide plate 510 facing the bracket 410. A through hole 411 is opened on the surface of the bracket 410 for the connecting plate 520 to pass through. A third hydraulic cylinder 530 is installed between the connecting plate 520 and the inner cavity of the bracket 410. The rotating component 600 is located on the slide plate 510. By activating the third hydraulic cylinder 530, the output end of the third hydraulic cylinder 530 can drive the connecting plate 520, the slide plate 510, the rotating component 600 and the mounting base 200 to move within a range of 300mm.

[0041] The rotating assembly 600 includes a housing component disposed between the slide plate 510 and the mounting base 200. A drive component is provided inside the housing component. The slide plate 510 is fixedly connected to one side of the housing component, and the mounting base 200 is movably connected to the other side of the housing component.

[0042] The housing component includes a first housing 610 fixedly connected to the side of the slide plate 510 away from the bracket 410, a second housing 620 integrally formed on the first housing 610, the second housing 620 communicating with the inner cavity of the first housing 610 and forming a receiving cavity for placing the drive component, and the mounting base 200 being movably connected to the surface of the first housing 610.

[0043] To facilitate maintenance and repair of the rock powder sampling and collection filtration device by allowing it to rotate at different heights, the drive component includes a motor 630 mounted on the second housing 620. The output shaft of the motor 630 passes through the inner cavity of the second housing 620 and is fixedly connected to a worm gear. The inner cavity of the first housing 610 is rotatably connected to a worm wheel that meshes with the worm gear via a pin. The worm wheel is fixedly connected to one side of the mounting base 200. By starting the motor 630, the output shaft of the motor 630 can drive the mounting base 200 to rotate 360° using the worm gear and worm wheel.

[0044] To visually indicate whether the rock powder sampling and collection filter device on the mounting base 200 is in the upright or inverted position, a limiting plate 511 is fixedly connected to the side of the slide plate 510 away from the bracket 410. The limiting plate 511 is located below the first housing 610. Both the top and bottom of the mounting base 200 are fixedly connected to protrusions 210. One side of the protrusion 210 can contact the limiting plate 511. When the mounting base 200 rotates, it can drive the protrusion 210 to rotate synchronously. When the protrusion 210 contacts the limiting plate 511, the rock powder sampling and collection filter device on the mounting base 200 is in the upright or inverted position.

[0045] When the 360° rotatable reverse circulation swing frame mechanism of the above technical solution is used, the first oil cylinder 320 is started. The output end of the first oil cylinder 320 can drive the swing seat 310 to swing within a 90° range around the pin between the swing seat 310 and the base 100. The swing seat 310 drives the pitch component 400, the compensation propulsion component 500, the rotation component 600, the mounting base 200 and the rock powder sampling and collection filter device to swing synchronously, so as to realize the position switching of the rock powder sampling and collection filter device between the transportation state and the working state.

[0046] When the second hydraulic cylinder 420 is started, the output end of the second hydraulic cylinder 420 can drive the bracket 410 to tilt within a range of 30° around the pin between the bracket 410 and the swing seat 310. The bracket 410 drives the compensation propulsion component 500, the rotating component 600, the mounting base 200 and the rock powder sampling and collection filter device to tilt synchronously, thereby realizing the tilt angle positioning of the rock powder sampling and collection filter device.

[0047] When the third hydraulic cylinder 530 is started, the output end of the third hydraulic cylinder 530 can drive the connecting plate 520 and the slide plate 510 to move within a range of 300mm on the surface of the bracket 410. The slide plate 510 drives the rotating component 600, the mounting base 200 and the rock powder sampling and collection filter device to move synchronously, thereby realizing the height positioning of the rock powder sampling and collection filter device.

[0048] When the motor 630 is started, the output shaft of the motor 630 can drive the worm gear to rotate. The worm gear drives the worm wheel, the mounting base 200 and the rock powder sampling and collection filter device to rotate 360°, which can realize the high and low rotation of the rock powder sampling and collection filter device for convenient maintenance and repair.

[0049] In summary, the components of the 360° rotatable reverse circulation swing frame mechanism of this utility model work together to provide a wide range of multi-angle adjustment functions. This ensures that the rock powder sampling and collection filtration device remains properly perpendicular to the ground, improving collection efficiency and safety. It meets the requirements for rock powder sampling and collection under various terrain conditions, and the overall structure is simple, safe, and reliable.
