Description

Technical Field

[0001] The utility model relates to the technical field of protective structures, and more specifically, to a castable protective structure used on a high-temperature heating surface of a garbage incineration boiler. Background Art

[0002] Refractory castables refer to a mixture of refractory aggregates, binders and admixtures, which are mixed with water to form a mud material that can be constructed by pouring. The difference from other amorphous refractory materials is that refractory castables have a certain coagulation and hardening time after construction. Therefore, after pouring and forming, they need to be cured for a certain period of time before demoulding, and then after an appropriate period of natural curing, they can be put into baking and use.

[0003] During the pouring process of the heating surface of a waste incineration boiler, operators often use corresponding protective structures to prevent the castable from leaking. Although the existing protective structures have basic protective functions in actual use, the general protective structures can only protect templates of a specific height due to their simple structure. When a higher template is required, a protective structure of the corresponding size needs to be replaced. This not only affects the efficiency of subsequent pouring operations, but also reduces the application scope of the structure. Therefore, it needs to be improved. Utility Model Content

[0023] like Figures 1 to 6 As shown, the utility model provides a castable protection structure for the high-temperature heating surface of a waste incineration boiler, comprising a base plate 1, fixedly connected to a fixing frame 2 on both sides of the top of the base plate 1, and movably connected to a rectangular plate No. 3 inside the fixing frame 2, and a rectangular groove 8 is provided at the bottom of the inner cavity of the fixing frame 2, and a mounting plate 4 is fixedly connected to the top of the rectangular plate No. 3, and the bottom of the mounting plate 4 is movably connected to the top of the fixing frame 2, and a driving motor 5 is fixedly connected to the front of the fixing frame 2, and the other end of the output shaft of the driving motor 5 is fixedly sleeved with a threaded rod 6, and the other end of the threaded rod 6 passes through the fixing frame 2 and extends to the interior of the fixing frame 2 and is threadedly sleeved with a moving block 7, and the outer surface of the moving block 7 is movably connected to the inside of the rectangular groove 8, and the top of the moving block 7 is hinged with an inclined rod 9, and the other end of the inclined rod 9 is hinged to the bottom of the rectangular plate No. 1.

[0024] When the driving motor 5 starts running, the threaded rod 6 will rotate, and the moving block 7 will move to the left under the limiting action of the rectangular slot 8, and the inclined rod 9 will start to move. At this time, under the limiting action of the fixing frame 2, the No. 1 rectangular plate 3 will drive the mounting plate 4 to move vertically upward.

[0025] Among them, a hollow plate 10 is movably connected between the fixing frames 2, a second rectangular plate 11 is movably connected inside the hollow plate 10, a fixed plate 12 is fixedly connected to the top of the second rectangular plate 11, and the bottom of the fixed plate 12 is movably connected to the top of the hollow plate 10.

[0026] When the fixed plate 12 moves, it will drive the second rectangular plate 11 to move vertically up and down under the limiting action of the hollow plate 10.

[0027] The left side of the mounting plate 4 is movably sleeved with a rotating rod 14 , the outer surface of the rotating rod 14 is fixedly sleeved with a rotating plate 15 , and the outer surface of the rotating plate 15 is movably connected with a sleeve rod 16 .

[0028] When the rotating rod 14 is rotated, the rotating plate 15 will rotate, and the rotating plate 15 will squeeze and push the two sleeve rods 16 to move.

[0029] Among them, the tops of both sides of the fixed plate 12 are fixedly connected with connecting plates 13, the inner side of the connecting plate 13 is fixedly connected to the outer side of the sleeve rod 16, and the outer surfaces of the fixed plate 12 and the connecting plate 13 are movably connected to the outer surface of the mounting plate 4.

[0030] When the sleeve rod 16 moves, the connecting plate 13 drives the fixing plate 12 to move horizontally back and forth.

[0031] Among them, the front of the mounting plate 4 is fixedly connected to a vertical plate 17 located on the right side of the rotating rod 14, and a pull rod 18 is movably sleeved inside the vertical plate 17. The left end of the pull rod 18 passes through the vertical plate 17 and extends to the left side of the vertical plate 17 and is fixedly connected to a locking block 19.

[0032] When the pull rod 18 is pulled, the locking block 19 will move left and right.

[0033] The outer surface of the locking block 19 is meshedly connected with a gear 20 , and the interior of the gear 20 is fixedly sleeved with the outer surface of the rotating rod 14 .

[0037] The working principle and use process of this utility model:

[0038] First, place the casting mold on the top of the base plate 1, and pull the pull rod 18 to make the locking block 19 move to the right, thereby releasing the fixing effect on the gear 20 and the rotating rod 14. Then rotate the rotating rod 14 to make the rotating plate 15 start to rotate, and squeeze and push the two sleeve rods 16 to move toward each other, so that the connecting plate 13 drives the fixed plate 12 to move horizontally toward each other under the limiting action of the mounting plate 4 and the fixing frame 2, finally achieving the fixing effect of molds of different sizes, improving the efficiency of the operator in fixing the mold, and reducing the labor intensity of the operator.

[0039] When it is necessary to perform protective operations on a mold with a higher height and the initial position of the structure does not meet the requirements, the drive motor 5 is started at this time, which will cause the threaded rod 6 to rotate, and the moving block 7 to move to the left under the limiting action of the rectangular groove 8, and the inclined rod 9 starts to move. At this time, under the limiting action of the fixed frame 2, the No. 1 rectangular plate 3 will drive the mounting plate 4 to move vertically upward, so that the connecting plate 13 will drive the fixed plate 12 and the No. 2 rectangular plate 11 to move upward together inside the hollow plate 10, thereby achieving the protection effect on molds of different heights and improving the application range of the structure.
