The pneumatic hand clamping device is developed aiming at brick arranging operation of a small flue brick wall of a coke oven regenerator, but the application occasion is not limited to the development, and the pneumatic hand clamping device can be used for construction in occasions with a plurality of parallel brick walls and proper spacing distances.
The following uses the construction process of the small flue of the regenerator of the coke oven as an example to explain the use method of the pneumatic hand clamping device:
the construction mode of the pneumatic hand clamping device is different from the traditional manual construction mode, and the construction mode is required to adopt an interval construction mode because the distance between 2 adjacent brick walls at the small flue part of the regenerator is small (generally 600-800 mm).

According to the drawing, paying-off positioning of the center line of the carbonization chamber at the end part of the coke oven is firstly carried out, and then the center line positions of other carbonization chambers are sequentially determined; and determining the center line position of the brick wall of the small flue of the lower regenerator according to the center line of the corresponding carbonization chamber, aligning the center line of the clamping mechanism on one side of the pneumatic clamping device with the center line of the brick wall on one side of the small flue of the end part after determining the position of the brick wall, and determining the initial position of the pneumatic clamping device.
Each brick wall is formed by combining clay bricks of different types, and the clay bricks are characterized by high compressive strength and can bear larger external force. The small flue of the regenerator is positioned at the bottommost part of the whole coke oven masonry, so that the clay bricks are most suitable for being used as brick wall materials of the small flue of the regenerator.
Three typical brick-type parts A, B, C for the brick wall construction of the small flue of the regenerator. The thickness and the width of the A-shaped brick are consistent with those of the B-shaped brick and the C-shaped brick, the length of the A-shaped brick is the sum of the length of the B-shaped brick and the length of the C-shaped brick, and the combined size of the B-shaped brick and the C-shaped brick is the same as that of the A-shaped brick.
Taking each brick wall as 12 layers as an example, wherein the 1 st layer and the 12 th layer are built by the A-type bricks, the other layers (namely the 2 nd layer to the 11 th layer) are built by the combination of the B-type bricks and the C-type bricks, and the adjacent 2 layers are built by staggered joint, so that the butt joint is forbidden.
The construction method adopts a 'pulp squeezing method', the length of mortar paved each time is not more than 75cm, and the mortar paved each time is not more than 50cm when the air temperature is higher than 30 ℃. The method can be used for continuously building 2-3 rows of bricks after one-time slurry paving, thereby reducing repeated actions of repeated slurry paving, having high building efficiency and particularly meeting the requirements of high speed and high precision of mechanized operation.
The pneumatic hand clamping device firstly carries out brick placing operation of the 1 st brick wall and the 3 rd brick wall, and all the bricks are placed from the 1 st layer to form A-shaped bricks. The clamping mechanisms at the two sides simultaneously and symmetrically perform brick placing operation. After all the A-shaped bricks of the 1 st layer are arranged, the combined brick arranging operation of the B-shaped bricks and the C-shaped bricks in the 2 nd layer to the 11 th layer is started, all the B-shaped bricks with larger relative sizes are arranged on each layer, and then the arranging operation of the C-shaped bricks with smaller relative sizes is carried out, so that the influence caused by 'pulp squeezing' can be reduced, and the masonry quality is improved. The adjacent 2 layers should be built in a staggered way, so that the butt joint of mortar joints is avoided, and the integrity of the wall is influenced. After the A-type bricks on the uppermost layer (layer 12) are built, the workers uniformly perform pointing operation on the overflowed mortar so as to ensure the overall appearance quality.
After the 1 st brick wall and the 3 rd brick wall are built, the hand clamping mechanism is restored to the original position, the pneumatic hand clamping device is moved to the next operation position, and the brick laying and building operation is carried out on the 2 nd brick wall and the 4 th brick wall from the center line alignment. And by analogy, constructing the 5 th brick wall, the 7 th brick wall, the 6 th brick wall and the 8 th brick wall … … until all brick walls are built.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
