[0028] See also Figure 1 , Figure 2 An inspection hole structure provided in an embodiment of the present application includes a cylinder 1 and a cover plate 2 covering the first end of the cylinder 1, a sealing gasket 3 is arranged between the cover plate 2 and the cylinder 1, and two hanging ears 4 are arranged at the first end of the cylinder 1 and are respectively located on both sides of the cover plate 2, and a clamping assembly 5 that can be detachably hung on the two hanging ears 4 and can press the cover plate 2 onto the cylinder 1 by rotation.

[0029] The embodiment of the present application provides an inspection hole structure, and the opening and closing process of the cover plate 2 is as follows: when the cover plate 2 needs to be opened, the pressing assembly 5 is first rotated by a certain angle to eliminate the pressing force of the pressing assembly 5 on the cover plate 2, and then the pressing assembly 5 is removed from the hanging ear 4. At this time, the cover plate 2 can be manually flipped by a certain angle or completely removed from the cylinder 1, thereby realizing the opening of the cover plate 2. When the cover plate 2 needs to be closed, the sealing gasket 3 is first placed on the end surface of the first end of the cylinder 1, and then the cover plate 2 is covered on the first end of the cylinder 1, and then the pressing assembly 5 is arranged above the cover plate 2 and hung on the two hanging ears 4, and then the pressing assembly 5 is rotated to press the cover plate 2 on the cylinder 1, so as to realize the sealing connection between the cover plate 2 and the first end of the cylinder 1.

[0030] Therefore, compared with the prior art, the present application does not require the cumbersome process of tightening bolts, nuts and other fasteners, and the operation is simple and convenient, and the cover plate 2 can be quickly opened and closed.

[0031] See also Figure 1 , exemplarily, the cylinder 1 is a rectangular parallelepiped structure surrounded by four side walls, the cover plate 2 is a rectangular structure, and the edge of the cover plate 2 is provided with a circle of baffles 21 extending toward the cylinder 1. When the cover plate 2 is covered on the first end of the cylinder 1, the first end of the cylinder 1 is located in the space surrounded by the cover plate 2 and the baffles 21. In other embodiments, the cylinder 1 can also be a cylindrical structure, and the cover plate 2 can be a circular structure.

[0032] See also Figure 2 The clamping assembly 5 includes a cylindrical clamping rod 51, on which an operating rod 52 is arranged, and connecting rods 53 eccentrically arranged therewith are fixed at both ends of the clamping rod 51, and the two connecting rods 53 are coaxially arranged and detachably hung on two hanging ears 4, respectively. The cover plate 2 is pressed onto the cylinder body 1 by rotating the clamping rod 51.

[0033] Specifically, the clamping rod 51 is a cylindrical structure, the operating rod 52 is perpendicular to the clamping rod 51, and one end of the operating rod 52 is fixedly connected to the middle position of the axial direction of the clamping rod 51. Two connecting rods 53 are coaxially arranged and respectively fixed on the end faces of the two ends of the clamping rod 51. The connecting rod 53 is parallel to the clamping rod 51 and eccentrically arranged. The outer diameter of the connecting rod 53 is smaller than the outer diameter of the clamping rod 51.

[0034] The process of using the above-mentioned clamping assembly 5 to clamp the cover plate 2 is as follows: the operator holds the operating rod 52, and hangs the two connecting rods 53 on the two hanging ears 4 respectively, and the operator holds the operating rod 52 to drive the clamping rod 51 to rotate, and the cover plate 2 is clamped on the cylinder body 1 through the outer peripheral surface of the clamping rod 51. The size of the clamping assembly 5 of the above-mentioned structure is much larger than the size of the bolt and nut, so even if the clamping assembly 5 is disassembled and buried in the ash material on site, it is easy to find and is not easy to be lost.

[0035] The pressing rod 51 may be a solid structure, for example, made of round steel. Figure 3, the clamping rod 51 is a hollow tubular structure, for example, made of a steel pipe. One end of the connecting rod 53 extends into the inner cavity of the clamping rod 51 and is fixedly connected to the clamping rod 51. For example, after one end of the connecting rod 53 is inserted into the inner cavity of the clamping rod 51, the outer surface of the connecting rod 53 contacts the inner surface of the clamping rod 51 and is welded. The two connecting rods 53 can be split structures, which are respectively fixedly connected to the clamping rod 51. Exemplarily, the two connecting rods 53 are an integrally formed structure, for example, the two connecting rods 53 are made of the same steel bar or round steel, so that the coaxiality of the two connecting rods 53 can be ensured. Of course, the connecting rod 53 can also be made of a steel pipe, which is not specifically limited here.

[0036] See also Figure 4 , the hanging ear 4 is provided with a hanging ear hole 41, and the connecting rod 53 is detachably inserted in the hanging ear hole 41. After the connecting rod 53 is inserted in the hanging ear hole 41, the connecting rod 53 can rotate in the hanging ear hole 41. For example, the hanging ear 4 can be a plate-like structure, and the hanging ear hole 41 is drilled on the plate-like structure by a drilling device. The hanging ear 4 can also include an inverted U-shaped steel bar, the two ends of the steel bar are connected to the cylinder 1, and the hanging ear hole 41 is surrounded between the steel bar and the cylinder 1. Among them, the size of the hanging ear hole 41 should be slightly larger than the cross-sectional size of the connecting rod 53, so that the connecting rod 53 can be easily inserted into the hanging ear hole 41. During operation, the operator holds the operating rod 52 and controls the operating rod 52 to move repeatedly along the axial direction of the pressing rod 51, thereby inserting the two connecting rods 53 into the hanging ear holes 41 of the two hanging ears 4 in turn or removing the two connecting rods 53 from the hanging ear holes 41 of the two hanging ears 4 in turn.

[0037] In order to improve the convenience of inserting the connecting rod 53 into the ear hole 41, see Figure 4 One side of the hanging ear 4 is provided with an opening 42 which is connected to the hanging ear hole 41 and allows the connecting rod 53 to pass through. During operation, the operator holds the operating rod 52 and controls the connecting rod 53 to move along the radial direction of the pressing rod 51, so that the two connecting rods 53 pass through the two openings 42 at the same time, and then the two connecting rods 53 are inserted into the two hanging ear holes 41 at the same time or the two connecting rods 53 are removed from the two hanging ear holes 41 at the same time.

[0038] The cover plate 2 may be directly covered on the first end of the cylinder 1, and no connection structure may be provided between the cover plate 2 and the cylinder 1. Figure 1 One side of the cover plate 2 is connected to the cylinder 1 through a hinge 6, and a handle 7 is provided on the cover plate 2. For example, the hinge 6 is provided between the stop bar 21 and the cylinder 1. After the pressing assembly 5 is removed, the operator holds the handle 7 to drive the cover plate 2 to flip upward, and the cover plate 2 can be rotated around the hinge 6 to open the cover plate 2. The angle of the cover plate 2 from the closed state to the open state is at least 90°.

[0039] See also Figure 5The sealing gasket 3 is provided with a positioning groove 31 on the side facing the cylinder 1, and the first end of the cylinder 1 is arranged in the positioning groove 31. For example, the sealing gasket 3 is a gasket with a V-shaped cross section. By providing the positioning groove 31 on the sealing gasket 3 to match the first end of the cylinder 1, when the sealing gasket 3 is installed on the first end of the cylinder 1, the position of the sealing gasket 3 can be positioned, avoiding the situation where the sealing gasket 3 is displaced due to external force and causes sealing failure, thereby improving the reliability of the seal.

[0040] See also Figure 6 An ash conveying device provided in an embodiment of the present application includes an ash conveying device body 8 and an inspection hole structure. An inspection port 81 is provided on the ash conveying device body 8. The second end of the cylinder 1 is fixed on the ash conveying device body 8, and the inner cavity of the ash conveying device body 8 is connected with the inner cavity of the cylinder 1 through the inspection port 81.

[0041] The embodiment of the present application provides an ash conveying device. When it is necessary to check the ash conveying and the wear of the device, the cover plate 2 can be opened first, and then the ash conveying and the wear of the device can be checked through the inspection port 81; after the inspection is completed, the cover plate 2 is covered on the first end of the cylinder 1, and the cover plate 2 is pressed on the cylinder 1 through the pressing assembly 5. Compared with the prior art, the present application does not require the cumbersome process of tightening fasteners such as bolts and nuts, and realizes the rapid opening and closing of the cover plate 2, while also avoiding the loss of parts.
