Technical Field

[0001] This utility model belongs to the technical field of shaft construction equipment, and relates to a ring-shaped rotary muck-removing device and a shaft tunneling machine containing the same. Background Technology

[0002] Shaft construction plays an irreplaceable role in mining, port construction, airport construction, power plant construction and other projects. With the continuous expansion of the scale of tunnel and underground engineering construction and the continuous increase in the depth of energy mining, the proportion of shaft construction is increasing year by year.

[0003] Currently, muck removal in shaft construction is generally achieved using a specialized hoisting system for shaft sinking, employing traditional methods such as buckets. This approach suffers from problems like discontinuous muck removal and low efficiency. For shaft excavation, especially for large-section deep shafts, muck removal is often a key factor determining the excavation speed. Furthermore, due to the spatial constraints of shafts, even with muck removal equipment, there are significant space limitations, resulting in limited improvement in muck removal efficiency.

The scraper removes the slag from the annular groove to the designated slag discharge point, ensuring continuous slag removal and improving slag removal efficiency.

[0036] The fixed end of the drive component is fixedly connected to the support component, and a scraper 6 is installed on the drive end of the drive component.

[0037] The scraper 6 is provided with multiple pieces arranged in a circumferential array, and all the scraper 6 pieces are arranged on the end face of the annular slag receiving trough 7 for storing slag.

[0038] The end face of the annular slag receiving trough 7 used for storing slag is located directly below the slag discharge trough, and the annular slag receiving trough 7 is provided with a discharge port corresponding to the discharge trough 8.

[0039] The unloading chute 8 is fixedly installed on the support assembly, and one end of the unloading chute 8 is located directly below the unloading port.

[0040] Preferably, the scraper 6 is disposed in a bent structure, and the bending direction of the scraper 6 is consistent with the rotation direction of the scraper 6, so that the slag is concentrated at the middle bend of the scraper 6. More preferably, the bending angle of the scraper 6 is set to 150°-170°.

[0041] More preferably, the scraper 6 is configured as a flexible structural component. Because the scraper 6 is made of flexible material, even if the slag is in the middle of the scraper 6 and the annular slag receiving groove 7, it will not impede the relative movement between the two.

[0042] Preferably, the unloading trough 8 is inclined, and the distance between the end of the unloading trough 8 directly below the annular slag receiving trough 7 and the lower end face of the annular slag receiving trough 7 is less than the distance between the other end of the unloading trough 8 and the lower end face of the annular slag receiving trough 7. More preferably, the inclination angle of the unloading trough 8 is preferably set to 30°-60°.

[0043] Preferably, the drive assembly includes a motor 2, an annular gear ring 3, and a connecting plate 5;

[0044] The fixed end of the motor 2 is fixedly connected to the support assembly via the support 4, and a gear is installed on the drive end of the motor 2.

[0045] The annular gear ring 3 includes an annular body and a gear ring that are movably connected. A bearing is provided between the gear ring and the annular body so that the gear ring and the annular body can rotate relative to each other. The gear ring is fixedly connected to multiple scrapers 6 through a connecting plate 5, and the gear ring meshes with a gear. The annular body is fixedly connected to the annular slag receiving trough 7. The multiple scrapers 6 are set on the end face of the annular slag receiving trough 7 for storing slag. The scrapers 6 rotate under the drive of the gear ring to push the slag in the annular slag receiving trough 7 to the position of the unloading trough 8.

[0046] More preferably, the connecting plate 5 is provided with multiple parts that correspond one-to-one with the scraper 6.

[0047] Furthermore, a reinforcing plate 9 is provided between two adjacent connecting plates 5 to prevent the connecting plates 5 from bending due to excessive force when removing slag, thereby improving the bending strength of the connecting plates 5.

[0048] Preferably, the slag lifting device 1 is provided with multiple slag conveying components arranged in a vertical direction, and each slag conveying component is provided with a slag dropping chute to achieve continuous slag discharge and improve slag discharge efficiency.

[0049] As a further embodiment of this utility model, except as described above, the specific structure of the slag lifting device 1 and the support assembly refers to the prior art.

[0050] As a further embodiment of this utility model, the specific process of using the above-described annular rotary slag remover for slag removal is as follows:

[0051] The slag lifting device 1 transports slag from the bottom of the shaft to the top of the device. Since the slag lifting device is rotating, the slag will fall evenly from its own slag drop chute into the annular slag receiving chute 7, realizing the 360° annular slag receiving function of the slag lifting device 1 during the rotation process.

[0052] Motor 2 is fixed on support 4, and ring gear 3 is connected to support 4 through bearings. Motor 2 and ring gear 3 are also connected by gear meshing.

[0053] When motor 2 rotates, it drives the ring gear to move in a circular motion along support 4 through gear meshing;

[0054] The connecting plate 5 and the scraper 6 are connected in sequence to the annular toothed ring 3. The annular toothed ring 3 drives the connecting plate 5 and the scraper 6 to scrape the slag in the annular slag receiving trough 7 to the gap in the annular slag receiving trough. The slag will fall from the gap onto the slope of the unloading trough, thereby completing the slag discharge operation.

[0055] As a further embodiment of the present invention, the present invention also provides a shaft tunneling machine, including a slag removal device and a ring-shaped rotary slag removal device as described above.

[0056] The support assembly is fixedly connected to the slag discharge device;

[0057] The drive end of the slag lifting device 1 is located at the slag discharge component of the slag discharge device. The slag discharge device transports the slag to the slag discharge component, and the slag lifting device 1 transports the slag from the slag discharge component to the annular slag receiving trough 7.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
