[0023] Example 1
[0024] like Figure 1-5 As shown, a rotary conveying mechanism for a cement rotary kiln brick-making equipment includes a steering connection structure and a set of pneumatic brick clamping devices at the upper and lower ends of the steering connection structure. The steering connection structure includes a set of spaced-apart rotating connecting frames 1 and a steering control structure between the two rotating frames. The steering control structure includes a steering connecting seat 2, an inner steering gear 3 in the inner ring of the steering connecting seat, a drive gear 4 meshing with the inner steering gear, and a drive motor 5 connected to the drive gear. The pneumatic brick clamping device includes a clamping body drive control structure between the steering connecting seat and the rotating connecting frame, and a brick clamping structure connected to the clamping body drive structure.
[0025] The clamping body drive control structure includes a set of telescopic control cylinders 6 whose ends are connected to the steering connecting seat, a set of built-in slide rails 7 located at the inner ends of the two rotating connecting frames, and a connecting slide seat 8 located on each built-in slide rail.
[0026] The outer end of each connecting slide is connected to the brick clamping structure, which includes an outer seat 9 connected to each connecting slide, a brick clamping seat 10 located between the two outer seat 9s, a pneumatic brick clamping assembly located inside the brick clamping seat, and a brick pushing assembly located at the rear of the pneumatic brick clamping assembly.
[0027] The pneumatic brick clamping assembly includes an inner connecting frame 11 inside the brick clamping seat, brick top clamping members 12 evenly distributed on the inner connecting frame, a top clamping cylinder group 13 located at the rear of the inner connecting frame and corresponding to each brick top clamping member, and a side brick clamping device located on each side end face of the brick clamping seat.
[0028] The side-end brick clamping device includes an outer connecting plate 14 located on the outside of the brick clamping seat, a side-end brick-tapping cylinder 15 located on the inside of the outer connecting plate and penetrating the brick clamping seat, and a brick-tapping block 16 located at the output end of the side-end brick-tapping cylinder.
[0029] The brick-pushing assembly includes a docking rail 17 located on the inner side of each brick clamping seat and connected to an inner sliding seat 24 located on the outer side of the inner connecting frame 11; a lateral brick-pushing rod 18 located between each docking rail; a linkage bottom pusher plate 19 located at the lower part of the lateral brick-pushing rod; and a brick-pushing motor 20 located outside the brick clamping seat. The output end of the brick-pushing motor 20 is connected to a transmission belt 21, and the transmission belt 21 is connected to a control active plate 22 located on the upper part of the inner connecting frame 11.
[0030] In practice: Taking a Φ4.8m rotary kiln as an example, the configuration includes: drive motor: 7.5kW servo motor, positioning accuracy ±0.1°, brick pushing mechanism: stroke 1200mm, thrust 12kN, infrared sensor: detection distance 0-500mm, resolution 1mm, and brick feeding system: brick shape optimization algorithm based on laser ranging.
[0031] The device rotates by a motor-driven gear. The gear is fixed in the central cylinder and driven to rotate by the motor. The large gear meshing with the gear is fixed and stationary on the folding mold frame. The rotary brick-feeding mechanism has brick-feeding mechanisms on both sides. The initial stage of the rotary brick-laying process involves a belt conveyor transporting a set of refractory bricks (4-12 bricks per set) into the brick-feeding mechanism. The brick-feeding mechanism operates, activating pneumatic grippers to clamp the refractory bricks. Then, the motor starts rotating gears to rotate the rotary brick-feeding mechanism. An infrared sensor is installed on the rotary brick-feeding mechanism. Once the mechanism reaches a predetermined angle, the motor stops driving the gears, and the electric guide rails on both sides of the mechanism start, moving the brick-feeding mechanism along the guide rails to the surface of the cylinder (movement occurs in two phases; the first phase is rapid, and the second phase is slow as the brick-feeding mechanism approaches the cylinder surface, until it reaches the surface). At this point, the pneumatic grippers release the refractory bricks, and the motor on the brick-feeding mechanism starts, driving the pusher rod in the brick-feeding mechanism along the inner guide rail to push the refractory bricks to the previous ring of bricks (first push, a total of two pushes). The brick-feeding mechanism moves along the guide rails... The bricks retract away from the refractory brick assembly. At this time, the brick-feeding mechanism's two side-mounted brick-tapping devices activate, compressing the refractory bricks to eliminate gaps between the circumferential refractory bricks. After the brick-tapping action is completed, the arc-shaped support plate on the mold frame compresses the refractory bricks via a cylinder / electric cylinder (first compression, a total of 2 compressions) and then retracts. The brick-feeding mechanism retracts half a brick along the guide rail for a second brick push. After the second brick push is completed, the arc-shaped support plate on the mold frame compresses the refractory bricks again via a cylinder / electric cylinder (second compression). Then, the motor drives the gears to rotate and rotate the mold frame. The brick feeding mechanism returns to its initial state, completing one circumferential brick feeding cycle. This process is repeated until the circumferential bricklaying reaches the top. Before the top is laid, the expansion cylinder in the top formwork extends and compresses the refractory bricks on both sides. The distance after expansion is recorded, and the bricks are allocated based on the calculated space. The required brick type and quantity are transmitted to the belt conveyor control terminal, where the required refractory bricks are transported and laid. After the last set of arc-shaped support plates presses the refractory bricks, the sealing bricks are manually driven in, completing the circumferential bricklaying process.
[0032] The advantages of this structure include: a gear-mold frame dynamic-static coupling transmission design for high-precision rotary positioning; brick joint accuracy control ≤1mm; a dual-speed guide rail propulsion and double-brick pressing mechanism to ensure compactness; a 90% reduction in the number of workers required for high-altitude operations; and a top gap adaptive compensation algorithm to dynamically optimize brick distribution. Overall, construction efficiency is increased by over 300%.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
