[0033] Example

[0034] Reference Figure 1 As shown, the present embodiment provides a rotary tunnel shaft slag cleaning device, which includes a safety platform 1, a turntable 2, a first drive device, a rotating shaft 3, a second drive device and a slag cleaning scraper. The turntable 2 extends in the vertical direction and is rotatably connected to the safety platform 1, that is, the turntable 2 is coaxially arranged with the safety platform 1. The first drive device is installed on the safety platform 1 and is transmission-connected to the turntable 2, and the turntable 2 is driven by the first drive device to rotate around its axis. The rotating shaft 3 is rotationally connected to the turntable 2 and is arranged inclined, and the second drive device is installed on the turntable 2 and is transmission-connected to the rotating shaft 3, driving the rotating shaft 3 to rotate around its axis. It should be noted that the first drive device and the second drive device can be installed inside the turntable 2 or outside the turntable 2. Figure 1 Not shown in the figure, each driving device can directly adopt a motor or other equipment. The slag scraper is installed on the rotating shaft 3 and rotates with the rotating shaft 3.

[0035] The rotary tunnel shaft slag cleaning device provided in the present embodiment utilizes the inclined arrangement of the rotating shaft 3 and the turntable 2 to expand the rotation range of the slag cleaning scraper, and when the slag cleaning scraper rotates in a large range with the turntable 2, the slag cleaning scraper itself also rotates in a small range with the rotating shaft 3, thereby improving the cleaning effect of the slag soil, and eliminating the need for manual operation, thereby improving the construction efficiency and safety factor.

[0036] Specifically, refer to Figure 2As shown, the slag scraper includes a side wall scraper 4 and a bottom wall scraper. A connecting rod 7 is connected to the middle position of the rotating shaft 3, and the side wall scraper 4 is connected to the end of the connecting rod 7 for scraping the slag on the side wall of the shaft; the bottom wall scraper is connected to the end of the rotating shaft 3 for scraping the slag on the bottom wall of the shaft. The axis of the rotating shaft 3 forms a first angle with the axis of the turntable 2, and the axis of the connecting rod 7 forms a second angle with the axis of the turntable 2, and the first angle is greater than the second angle. The scraping diameter of the side wall is greater than the scraping diameter of the bottom wall, so that the slag is concentrated in the slag chute at the center of the shaft, taking into account the scraping of the slag on the side wall and the bottom wall of the shaft.

[0037] Specifically, the rotating shaft 3 includes a first section 8 and a second section 9, the side wall scraper 4 is connected to the first section 8, and the bottom wall scraper is connected to the end of the second section 9, and the second section 9 is an electric telescopic rod. When scraping the bottom wall, the electric telescopic rod can be gradually extended as the scraping operation proceeds to increase the scraping depth of the bottom wall scraper, thereby better scraping the debris on the bottom wall.

[0038] Specifically, the turntable 2 rotates in the first direction, and the side wall scraper 4 tilts upward along the first direction so that the side wall scraper 4 scrapes the slag downward as the turntable 2 rotates; that is, the side wall scraper 4 includes a first end and a second end, and the direction from the first end to the second end is the first direction, so that the height of the second end is higher than the height of the first end, so that the side wall scraper 4 scrapes the slag downward as the turntable 2 rotates. The rotating shaft 3 rotates in the second direction, and the bottom wall scraper tilts upward along the second direction so that the bottom wall scraper scrapes the slag downward as the rotating shaft 3 rotates, and the bottom wall scraper is the same as the side wall scraper 4. Thereby, the slag can be better concentrated to the slag chute at the center of the shaft during the scraping operation.

[0039] Specifically, the first direction and the second direction are in the same direction, that is, the first direction and the second direction are both counterclockwise or clockwise.

[0040] Specifically, the bottom wall scraper includes a first scraper 5 and a second scraper 6; the first scraper 5 includes a first triangular edge profile; the second scraper 6 includes a second strip-shaped edge profile. The first scraper 5 has a triangular first edge profile that can be inserted into the slag to move the slag, and the second scraper 6 has a strip-shaped second edge profile that can increase the contact area with the slag, thereby improving the efficiency of scraping the slag.

[0041] Specifically, refer to Figure 3As shown, the second scraper 6 includes a rigid portion 10 and a flexible portion 11. The flexible portion 11 is arranged along the edge of the rigid portion 10 so that the flexible portion 11 first contacts the soil when the second scraper 6 scrapes the soil. The flexible portion 11 is made of rubber material. When the second scraper 6 contacts overly hard gravel, soil, etc., the flexible portion 11 can be deformed to ensure smooth rotation of the rotating shaft 3 and the turntable 2. Hard gravel, soil, etc. can be removed by repeated scraping.

[0042] Specifically, refer to Figure 4 As shown, a support portion is provided at the edge of the safety platform, and the support portion includes four telescopic cylinders 12, and the four telescopic cylinders 12 are symmetrically arranged in pairs. When performing slag cleaning operations, the telescopic cylinders 12 are extended and abut against the wall of the shaft to fix the slag cleaning device and maintain stability during the slag cleaning process.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
