[0016] By adopting the above technical solution, the beneficial effects of the present invention are:

[0017] The head section, belt storage section, transition section and straight section of the frame are all set in the straight section of the tunnel. When a turn occurs during tunnel construction, the turning section frame is installed at the turning section of the tunnel. The angle adjustment connecting frame can keep the turning section frame at the center of the turning section of the tunnel during installation. The cooperation of the angle adjustment connecting frame and the turning section frame can ensure the belt conveyor can perform turning and conveying operations in tunnels with different angles and curvatures.

[0018] A connecting frame is provided at the rear side of the tail frame, which is fixed to the rear end of the shield machine through the connecting frame, so that the tail frame is fixedly connected to the shield machine, and the tail frame can achieve the following operation with the shield machine; when the tail frame is following the operation, it slowly advances towards the shield machine, and the conveyor belt tensioning trolley on the belt storage section moves on the slide rail to slowly unwind the conveyor belt, so that the conveyor belt can follow the tail frame for mobile conveying operation. As the tail frame continues to move, when the conveyor belt tensioning trolley moves to the limit, the shield machine stops excavating, the belt conveyor is closed, and the stored conveyor belt is connected to the conveyor belt of the frame through the conveyor belt unwinding mechanism. When the conveyor belt on the unwinding mechanism is completely moved to the frame, the conveyor belt tensioning trolley returns to the initial position, and the shield machine starts excavating, and the belt conveyor resumes the conveying operation;

[0019] An upper turning roller group is provided on the fifth mounting frame of the turning section. When the conveyor belt is loaded with materials for turning transportation, if the deflection angle of the conveyor belt when turning is not adjusted, the materials will fall to the ground. In severe cases, the conveyor belt may overturn or wind up. Therefore, an upper turning roller group and a lower turning roller group are provided on the fifth mounting frame of the turning section. The operating angles of the first upper curved beam and the second upper curved beam of the upper turning roller group can be adjusted by a connecting rod to ensure that the conveyor belt is in a safe deflected conveying state when turning transportation. A single upper curved beam can be raised up to 30 degrees at most, so that the upper roller group of the turn can generate a lateral thrust on the conveyor belt to balance the centripetal force of the conveyor belt. The blocking roller can control the conveying position without displacement, and the pressure roller can prevent the conveyor belt from tipping over. The lower roller group of the turn adopts a V-shaped roller group structure. The operating angles of the first upper straight beam and the second upper straight beam can be adjusted by the connecting rod. A single upper straight beam can be raised up to 10 degrees at most, so that the conveyor belt will not deviate or flip when the empty belt turns and turns. A pressure roller mechanism is also provided on the fifth mounting frame of the turn section. The upper and lower pressure rollers of the pressure roller mechanism can provide downward pressure when the conveyor belt turns again, ensuring that the conveyor belt can perform turning and transportation operations stably and safely. An angle adjustment connecting frame is provided between the two turning sections. The curvature of the angle adjustment connecting frame can be adjusted according to the curvature of the tunnel, so that the turning section can be stably installed in the middle position of the tunnel. A conveying opening is provided on the maintenance platform at the front end of the tail frame. The inner wall of the conveying opening is provided with scale markings. The conveyor belt on the turning section passes through the conveying opening. The opening is connected with the second driving roller, buffer roller group and adjustable groove angle roller group on the tail frame. The inner wall of the conveying opening is provided with scale markings, which can show the relative distance between the turning section and the tail frame. When the tail frame follows the shield machine to move, it will slowly increase the distance from the rear turning section. When the scale markings show that the distance between the turning section and the tail frame reaches the maximum value, the shield machine and the belt conveyor stop working, and a turning section is added at the end of the turning section. After the addition is completed, the shield machine and the belt conveyor stop working. The machine can be started and continue to operate; the side of the legs of the fifth mounting frame in the turning section are each provided with an anti-rollover mechanism. When the belt conveyor is turning and conveying, not only the conveyor belt has to bear the centripetal force, but the fifth mounting frame will also bear the deflection force generated during the turning and conveying. By pulling open the support rod so that its lower end is against the tunnel ground, and tightening the fastening screws, the fifth mounting frame can obtain the support force of the anti-rollover mechanism, thereby preventing the fifth mounting frame from rolling over due to the large deflection force generated by the turning and conveying operation of the belt conveyor;

[0020] A conveyor belt cleaning device is provided on the first mounting frame. When the material conveyed by the conveyor belt is highly viscous, some of the material will stick to the conveyor belt after unloading. These highly viscous materials cannot be hung off by simply passing through the hanging plate. A conveyor belt cleaning device is provided on the first mounting frame. The conveyor belt is firstly cleaned by scraping by the hanging plate, and then passes through the first flushing chamber, the brushing chamber and the second flushing chamber of the conveyor belt cleaning device. After flushing by the nozzle, brushing by the rotating shaft brush and flushing by the nozzle again, the conveyor belt can be cleaned.

[0021] In summary, the present invention provides a turning adjustable conveyor, in which the head section, belt storage section, transition section and straight section of the frame are all arranged in the straight section of the tunnel. When a turn occurs during tunnel construction, the turning section frame is installed at the turning point of the tunnel, and the turning section frame can be kept at the center of the turning section of the tunnel during installation through the angle adjustment connecting frame. The cooperation of the angle adjustment connecting frame and the turning section frame can ensure the belt conveyor to perform turning and conveying operations in tunnels with different angles and curvatures, thereby solving the problem that the existing straight belt conveyor cannot meet the belt conveying operations when tunnels and lanes turn.

[0053] By adopting the above technical solution, the method of using the present invention is:

[0054] By adopting the above technical solution, the beneficial effects of the present invention are:

[0055] The head section, belt storage section, transition section and straight section of the frame are all arranged in the straight section of the tunnel. When a turn occurs during tunnel construction, the turning section frame is installed at the turning section of the tunnel. The angle adjustment connecting frame 18 can be used to keep the turning section frame at the center of the turning section of the tunnel during installation. The cooperation of the angle adjustment connecting frame 18 and the turning section frame can ensure the belt conveyor to perform turning and conveying operations in tunnels with different angles and curvatures.

[0056] A connecting frame 18 is provided at the rear side of the tail frame 14, which is fixed to the rear end of the shield machine through the connecting frame 18, so that the tail frame 14 is fixedly connected to the shield machine, and the tail frame 14 realizes the following operation with the shield machine; when the tail frame 14 is performing the following operation, it slowly advances towards the shield machine, and the conveyor belt tightening trolley 9 on the belt storage section moves on the slide rail to slowly unwind the conveyor belt, so that the conveyor belt can follow the tail frame 14 to perform mobile conveying operations. As the tail frame 14 continues to move, when the conveyor belt tightening trolley 9 moves to the limit, the shield machine stops excavating, the belt conveyor is closed, and the stored conveyor belt is connected to the conveyor belt of the frame through the conveyor belt unwinding mechanism. When the conveyor belt on the unwinding mechanism is completely moved to the frame, the conveyor belt tightening trolley 9 returns to the initial position, and the shield machine starts excavating, and the belt conveyor restarts the conveying operation;

[0057] An upper turning roller group is provided on the fifth mounting frame 13 of the turning section. When the conveyor belt is loaded with materials for turning transportation, if the deflection angle of the conveyor belt when turning is not adjusted, the materials will fall to the ground, and in severe cases, the conveyor belt will overturn or wind up. Therefore, an upper turning roller group and a lower turning roller group are provided on the fifth mounting frame 13 of the turning section. The operating angles of the first upper curved beam 20 and the second upper curved beam 21 of the upper turning roller group can be adjusted by a connecting rod to ensure that the conveyor belt is in a safe deflected conveying state when turning transportation. A single upper curved beam can be raised up to 30 degrees at most, so that the upper roller group on the turning can generate a lateral thrust on the conveyor belt to balance the centripetal force of the conveyor belt. The blocking roller can control the conveying position without displacement, and the pressure roller 25 can prevent the conveyor belt from tipping over. The lower roller group on the turning adopts a V-shaped roller group structure. The operating angles of the first upper straight beam 30 and the second upper straight beam 31 can be adjusted by the connecting rod. The single upper straight beam 0 can be raised up to 10 degrees at most, so that the conveyor belt will not deviate or flip when the empty belt turns. The fifth mounting frame 13 of the turning section A roller mechanism is also provided on the top, and the upper roller 37 and the lower roller 40 of the roller mechanism can provide downward pressure when the conveyor belt is turned and transported, so as to ensure that the conveyor belt can be turned and transported stably and safely; an angle adjustment connecting frame 18 is provided between the two turning sections, and the curvature of the angle adjustment connecting frame 18 can be adjusted according to the curvature of the tunnel, so that the turning section can be stably installed in the middle position of the tunnel; a maintenance platform 17 at the front end of the tail frame 14 is provided with a conveying opening, and a scale mark is provided on the inner side wall of the conveying opening, and the conveyor belt on the turning section passes through the conveying The opening is connected to the second driving roller 15, the buffer roller group and the adjustable groove angle roller group on the tail frame 14. A scale mark is provided on the inner wall of the conveying opening. The scale mark can show the relative distance between the turning section and the tail frame 14. When the tail frame 14 follows the shield machine to move, it will slowly pull away from the rear turning section. When the scale mark shows that the distance between the turning section and the tail frame 14 reaches the maximum value, the shield machine and the belt conveyor stop working, and a turning section is added at the end of the turning section. After the addition is completed, the shield machine and the belt conveyor stop working. The machine can be started and continue to operate; the side of the legs of the fifth mounting frame 13 of the turning section are each provided with an anti-rollover mechanism. When the belt conveyor is turning and conveying, not only the conveyor belt will be subjected to the centripetal force, but the fifth mounting frame 13 will also be subjected to the deflection force generated during the turning and conveying. By pulling open the support rod 58 so that its lower end is against the tunnel ground and tightening the fastening screws, the fifth mounting frame 13 can obtain the support force of the anti-rollover mechanism, thereby preventing the fifth mounting frame 13 from rolling over due to the large deflection force generated by the turning and conveying operation of the belt conveyor;

[0058] A conveyor belt cleaning device is provided on the first mounting frame 4. When the material conveyed by the conveyor belt is highly viscous, some of the material will adhere to the conveyor belt after unloading. These highly viscous materials cannot be hung off by simply passing through the hanging plate. A conveyor belt cleaning device is provided on the first mounting frame 4. The conveyor belt is firstly cleaned by scraping by the hanging plate, and then passes through the first flushing chamber 62, the brushing chamber 63 and the second flushing chamber 64 of the conveyor belt cleaning device. After being flushed by the nozzle 68, brushed by the bristles of the rotating shaft 69 and flushed again by the nozzle 68, the conveyor belt can be cleaned.

[0059] In summary, the present invention provides a turning adjustable conveyor, in which the head section, belt storage section, transition section and straight section of the frame are all arranged in the straight section of the tunnel. When a turn occurs during tunnel construction, the turning section frame is installed at the turning point of the tunnel. The angle-adjusting connecting frame 18 can keep the turning section frame at the center of the turning section of the tunnel during installation. The cooperation of the angle-adjusting connecting frame 18 and the turning section frame can ensure the belt conveyor to perform turning and conveying operations in tunnels with different angles and curvatures, thereby solving the problem that the existing straight belt conveyor cannot meet the belt conveying operations when tunnels and lanes turn.
