The 2 clamping hand plates are respectively fixedly connected with the cylinder body of the short-stroke cylinder and the push plate at the end part of the cylinder push rod through screws, the opening and closing range of the clamping hand plates is larger than the overall dimension of various common brick types of the coke oven, prefabricated holes are reserved on the cylinder body of the short-stroke cylinder, and the clamping hand plates are conveniently connected with the push plate at the end part of the cylinder rod of the vertical cylinder. The prefabricated holes on the cylinder bodies of all the cylinders need to be kept away from the hollow part.
The hand clamping plate in the hand clamping mechanism cannot be too thick, but is made of a material with certain rigidity, so that the hand clamping mechanism is not easy to deform.
The pneumatic clamping hand device is developed aiming at brick swinging operation of a small flue brick wall of a coke oven regenerator, but the application occasion is not limited to the pneumatic clamping hand device, and the pneumatic clamping hand device can be used for construction in any occasion with a plurality of parallel brick walls and proper spacing distance.
The use method of the pneumatic clamping device is described by taking the building process of the small flue of the regenerative chamber of the coke oven as an example:
the construction mode of the pneumatic clamping hand device is different from the traditional manual building mode, and the space between the adjacent 2 brick walls at the small flue part of the regenerator is very small (usually 600-800 mm), so that the mode of building at intervals is needed.
Firstly, the portal frame of the pneumatic clamping device is arranged on two sides of the basic top plate of the coke oven in a crossing way, and 2 bases are respectively arranged on a machine side platform and a coke side platform of the coke oven.
According to a drawing, firstly carrying out paying-off positioning on the central line of the coking chamber at the end part of the coke oven, and then sequentially determining the positions of the central lines of other coking chambers; and determining the central line position of the brick wall of the lower regenerator small flue according to the central line of the corresponding carbonization chamber, aligning the central line of the clamping mechanism at one side of the pneumatic clamping hand device with the central line of the brick wall at one side of the end small flue after the brick wall position is determined, and determining the initial position of the pneumatic clamping hand device.
Each brick wall is formed by combining clay bricks of various types, and the clay bricks have the characteristics of high compressive strength and capability of bearing larger external force. The small flue of the heat storage chamber is positioned at the bottommost part of the whole coke oven masonry, so the clay brick is most suitable for being used as a brick wall material of the small flue of the heat storage chamber.
The typical brick types for building the small flue brick wall of the regenerator are A, B, C. 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 size of the combined 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 A-type bricks, the rest layers (namely the 2 nd layer to the 11 th layer) are built by combining B-type bricks and C-type bricks, and the adjacent 2 layers are staggered and overlapped, and are strictly forbidden to be butt-jointed.
The masonry method adopts a 'squeezing method', the length of mortar laid each time is not more than 75cm, and when the temperature is higher than 30 ℃, the length is not more than 50 cm. By adopting the squeezing method, 2-3 rows of bricks can be continuously built after once slurry spreading, so that repeated actions of multiple slurry spreading are reduced, the building efficiency is high, and the requirements of high speed and high precision of mechanized operation are particularly met.
The pneumatic clamping hand device firstly carries out brick placing operation on the 1 st brick wall and the 3 rd brick wall, and the placed bricks are all A-shaped bricks from the 1 st layer. The clamping hand mechanisms on the two sides simultaneously and symmetrically perform brick swinging operation. After all the A-shaped bricks on the 1 st layer are laid, the combined brick laying 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 laid on each layer, and then the C-shaped bricks with smaller relative sizes are laid, so that the influence caused by 'pulp squeezing' can be reduced, and the laying quality is improved. The adjacent 2 layers should be constructed in a staggered mode, so that the integrity of the wall body is prevented from being influenced by butt joint of mortar joints. After the A-shaped bricks on the uppermost layer (the 12 th layer) are built, joint pointing operation is uniformly carried out on overflowed mortar by workers so as to ensure the overall appearance quality.
And after the 1 st brick wall and the 3 rd brick wall are laid, returning the clamping hand mechanism to the original position, moving the pneumatic clamping hand device to the next operation position, and performing brick laying and laying operation on the 2 nd brick wall and the 4 th brick wall from the alignment of the central lines. And by analogy, the 5 th brick wall and the 7 th brick wall, and the 6 th brick wall and the 8 th brick wall … … are constructed until all the brick walls are built.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.

4) building by adopting a pulp squeezing method, and continuously building 2-3 rows of bricks after once pulp spreading; the pneumatic clamping hand device firstly carries out brick placing operation on the 1 st floor from the 1 st brick wall and the 3 rd brick wall at the same time, after all the A-shaped bricks on the 1 st floor are placed, brick placing operation from the 2 nd floor to the n-1 st floor is started, in the process, all the B-shaped bricks are placed on each floor, and then the C-shaped bricks are placed; finally, placing the A-shaped bricks in the 12 th layer; after all placement is finished, manual pointing operation is carried out;
5) after the 1 st brick wall and the 3 rd brick wall are built, the combined cylinder and the clamping hand mechanism return to the original positions, the pneumatic clamping hand device is moved to the next working position, and the 2 nd brick wall and the 4 th brick wall are built;
6) and by parity of reasoning, the 5 th brick wall and the 7 th brick wall, and the 6 th brick wall and the 8 th brick wall … … are built in sequence until the brick walls forming the small flues of the regenerator are completely built.
6. The brick laying method for the small flue brick wall of the regenerative chamber of the coke oven as claimed in claim 5, wherein in the step 4), when the air temperature is lower than 30 ℃, the length of mortar laid each time is not more than 75 cm; when the air temperature is more than or equal to 30 ℃, the length of the mortar laid every time is not more than 50 cm.
7. The brick placing and building method for the small flue brick wall of the coke oven regenerator as claimed in claim 1, wherein in the step 4), when the pneumatic gripper device swings bricks, the combined cylinders and gripper mechanisms on two sides act symmetrically at the same time.
