They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a special bearing assembly device for a tunneling machine includes a fixed plate 101, a rotating drum 102 coaxially rotatably connected to the upper end of the fixed plate 101, a fixed frame 103 fixedly connected to the upper end of the rotating drum 102, a fixing mechanism on the fixed plate 101, and an adjusting mechanism on the rotating drum 102.

[0026] The adjusting mechanism includes two grooves 401, which are radially symmetrical along the rotating drum 102. The grooves 401 correspond vertically to the fixed frame 103. A movable frame 402 is slidably connected within the grooves 401. The symmetrical movable frames 402 are V-shaped with their tips pointing upwards. Multiple equidistant limiting grooves are formed within the grooves 401. A pin is slidably connected to one end of the movable frame 402 near the groove 401, and an adjusting plate 403 is slidably connected to the other end of the movable frame 402 away from the groove 401. A locking knob is threaded onto one end of the movable frame 402 near the adjusting plate 403. A sliding groove 404 is formed on the side of the adjusting plate 403 near the fixed frame 103. The sliding groove 404 is T-shaped. The end of the adjusting plate 403 away from the movable frame 402 is a horizontal section with a feed hole 405. The fixed connection has multiple spring pieces. In use, first fix the fixed plate 101 inside the bearing, so that the bearing and the fixed plate 101 are coaxial. Then rotate the locking knobs on both sides and adjust the adjusting plate 403. The adjusting plate 403 slides with the moving frame 402 so that the feed hole 405 corresponds to the bolt through hole, which is convenient for adjustment according to different bearing specifications. Then pull out the pin and adjust the distance between the lower end of the adjusting plate 403 and the threaded through hole so that the feed hole 405 is close to the threaded through hole. Then insert the pin into the limiting groove. Then arrange the fixing bolts into the sliding groove 404. The fixing bolts slide into the feed hole 405 by the inclined adjusting plate 403. Then press the fixing bolts down to deform the spring piece and disengage from the fixing bolt. Then the next fixing bolt slides into the feed hole 405 and corresponds to the bolt through hole.

[0027] The fixed frame 103 has symmetrical moving slots 301. A bidirectional lead screw 302 is rotatably connected in the moving slots 301. A turntable 303 is rotatably connected to one end of the fixed frame 103. The turntable 303 is fixedly connected to the bidirectional lead screw 302. Rotating the turntable 303 drives the bidirectional lead screw 302 to rotate.

[0028] The two-way lead screw 302 has symmetrical moving blocks 501 threaded on both sides. The lower end of the moving blocks 501 is fixedly connected to symmetrical electric telescopic rods 502. The lower end of the electric telescopic rods 502 is fixedly connected to a connecting plate 503.

[0029] A DC motor 601 is fixedly installed on the upper end of the connecting plate 503. The DC motor 601 is located between symmetrical electric telescopic rods 502. The output shaft of the DC motor 601 is fixedly connected to a clamp. A screwdriver 602 is fixedly installed on the lower end of the clamp. The moving block 501 is threadedly connected to the bidirectional lead screw 302, so that the symmetrical moving blocks 501 move towards each other on the bidirectional lead screw 302. This causes the connecting plate 503 to drive the DC motor 601 to move to correspond with the feed hole 405. Then, the electric telescopic rod 502 drives the connecting plate 503 to descend, so that the screwdriver 602 abuts against the fixing bolt and presses the fixing bolt downward, causing the fixing bolt to disengage from the feed hole 405. At the same time, the DC motor 601 drives the screwdriver 602 to rotate, and the bearing seat and bearing cover are fixedly connected by the fixing bolt.

[0030] The fixing mechanism includes multiple electric push rods 201, which are evenly distributed around the fixed plate 101. A rubber block 202 is fixedly connected to the end of the electric push rod 201 away from the fixed plate 101. The rubber block 202 is made of elastic material. When in use, the electric push rod 201 drives the rubber block 202 away from the fixed plate 101, so that the rubber block 202 abuts against the inner side of the bearing.

[0031] A servo motor 7 is fixedly connected to the lower end of the fixed plate 101. The output shaft of the servo motor 7 is fixedly connected to the rotating drum 102. After adjustment, the servo motor 7 intermittently drives the rotating drum 102 to rotate, so that the adjustment plates 403 on both sides rotate synchronously, which can improve processing efficiency.

[0032] The upper end of the fixed frame 103 is fixedly connected with two symmetrical fixed rings 8. The fixed rings 8 are located above the moving groove 301. The device is hoisted into the bearing. After the rubber block 202 abuts against the inner side of the bearing, the hoisting rope is removed.

[0033] Working principle: During use, the device is hoisted into the bearing. Then, the electric push rod 201 drives the rubber block 202 away from the fixed plate 101, causing the rubber block 202 to abut against the inner side of the bearing. The bearing and the fixed plate 101 are coaxial. The hoisting rope is then removed. Next, the locking knobs on both sides are rotated, and the adjusting plate 403 is adjusted. The adjusting plate 403 slides against the moving frame 402, aligning the feed hole 405 with the bolt through hole, facilitating adjustment according to different bearing specifications. Then, the pin is pulled out, and the distance between the lower end of the adjusting plate 403 and the threaded through hole is adjusted, bringing the feed hole 405 closer to the threaded through hole. The pin is then inserted into the limiting groove. The fixing bolts are then arranged and placed in the sliding groove 404. The tilted adjusting plate 403 causes the lowest fixing bolt to slide into the feed hole 405. Finally, the turntable 303 is rotated to drive the bidirectional lead screw 3. 02. Rotation: The moving block 501 is threadedly connected to the bidirectional lead screw 302, causing the symmetrical moving blocks 501 to move towards each other on the bidirectional lead screw 302. This causes the connecting plate 503 to drive the DC motor 601 to move to correspond with the feed hole 405. Subsequently, the electric telescopic rod 502 drives the connecting plate 503 to descend, causing the screwdriver 602 to abut against the fixing bolt and press down on the fixing bolt, causing the spring to deform and disengage from the fixing bolt. At the same time, the DC motor 601 drives the screwdriver 602 to rotate, and the fixing bolt fixes the bearing seat to the bearing cover. Then, the connecting plate 503 rises, and the next fixing bolt slides into the feed hole 405 and corresponds to the bolt through hole. After adjustment, the servo motor 7 intermittently drives the rotating drum 102 to rotate, causing the adjusting plates 403 on both sides to rotate synchronously, which helps to improve processing efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
