[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Integrated coke oven vent pipe cover, such as Figures 1 to 8As shown, it includes a cylinder 1 and a cover plate 2 installed on the top of the cylinder 1. A flipping mechanism that drives the cover plate 2 to flip is installed on the cylinder 1. The flipping mechanism is connected to a drive mechanism integrally set on the cylinder 1.

[0028] The flipping mechanism includes a flipping arm 4, one end of which is connected to the cover plate 2. The two sides of the flipping arm 4 are respectively hinged to the support frame 3 symmetrically arranged on the side wall of the cylinder 1. The flipping arm 4 rotates under the drive of the drive mechanism, thereby causing the cover plate 2 to flip.

[0029] A second hinge seat 10 is provided on the outside of the support frame 3, and the flip arm 4 is connected to the second hinge seat 10 through the hinge shaft 11.

[0030] The support frame 3 is arranged in an inverted right triangle, and the support frame 3 is connected to the side wall of the cylinder 1 by a gasket 28.

[0031] The drive mechanism includes a hydraulic cylinder 9 mounted on the side wall of the cylinder 1 via a hydraulic cylinder mounting seat 23, such as Figure 2 As shown, the movable end of the hydraulic cylinder 9 is connected to the tilting arm 4, and the tilting arm 4 can rotate around the hinge shaft 11 by extending and retracting the movable end of the hydraulic cylinder 9.

[0032] The drive mechanism can be directly welded to the side wall of the cylinder 1, or it can be connected to the cylinder 1 by welding a welding plate 22 that fits the side wall of the cylinder 1.

[0033] The tilting arm 4 includes two symmetrically arranged bending rods, such as Figure 6 As shown, the bending rod includes a horizontal part 18 and a bending part 19. The horizontal part 18 and the bending part 19 are connected by a first reinforcing rod 20, and the two bending parts 19 are connected by a number of second reinforcing rods 21 to ensure the stability of the tilting arm 4.

[0034] A horizontal mounting plate 6 is installed between the two support frames 3, such as Figure 5 As shown, the mounting plate 6 is integrally set with the side wall of the cylinder 1 on one side. The cover plate 2 is connected to the mounting plate 6 through a linkage mechanism. When the tilting arm 4 rotates, it can lift the cover plate 2 up a certain distance to avoid wear at the contact point between the cover plate 2 and the cylinder 1, thus affecting the service life of the cover plate.

[0035] The linkage mechanism includes a first hinge seat 7 symmetrically arranged on the mounting plate 6, a pull rod 8 hinged on the first hinge seat 7, and the other end of the pull rod 8 hinged to the cover plate 2.

[0036] When the cover plate 2 is flipped by the flipping arm 4, the linkage mechanism works in conjunction with the cover plate 2 to achieve the flipping and resetting of the cover plate 2.

[0037] The top of the cover plate 2 is provided with a first reinforcing rib plate 14 and a second reinforcing rib plate 15, which are arranged in a cross shape.

[0038] The first reinforcing rib plate 14 is arranged parallel to the mounting plate 6, and vertical connecting plates 12 are respectively provided at both ends of the first reinforcing rib plate 14. The vertical connecting plates 12 are connected to the ends of the tilting arm 4.

[0039] A third reinforcing rib 16 is provided at the end of the second reinforcing rib 15 near the mounting plate 6. The third reinforcing rib 16 is perpendicular to the second reinforcing rib 15. Vertical side plates 17 are provided at both ends of the third reinforcing rib 16. The bottom of the vertical side plates 17 is hinged to the tie rod 8.

[0040] like Figure 3 As shown, the cover plate 2 is also provided with refractory fiber blocks 13. When high-temperature exhaust gas is discharged, the refractory layer blocks the high-temperature exhaust gas, preventing the high-temperature exhaust gas from directly contacting the cover plate 2 and preventing the cover plate 2 from being damaged by high-temperature impact.

[0041] Specifically, such as Figure 7 As shown, the refractory fiber block 13 has a threaded hole in the middle, the cover plate 2 has a threaded groove, and a pad 27 is provided between the refractory fiber block 13 and the cover plate 2. The bolt 26 passes through the central threaded hole of the refractory fiber block 13, the central threaded hole of the pad 27, and the threaded groove on the cover plate 2 in one threaded connection.

[0042] A counterweight 5 is provided at the end of the tilting arm 4 away from the cover plate 2. The weight of the counterweight 5 is greater than the weight of the cover plate 2. When the oil cylinder in the drive mechanism fails, the counterweight 5 can drive the cover plate 2 to tilt under its own weight, open the vent pipe to release the high-temperature exhaust gas, and avoid the high-temperature exhaust gas from accumulating inside the vent pipe and causing safety hazards.

[0043] The number of counterweights 5 can be selected according to actual needs. In this embodiment, there are two counterweights 5, and the counterweights 5 are installed on the tilting arm 4 by bolt assembly.

[0044] The lower part of the cylinder 1 is also equipped with a buffer mechanism 25, which acts as a buffer. Figure 8 As shown, the buffer mechanism includes a bottom plate 29, a top plate 30, and a buffer spring 31. One end of the buffer spring 31 is connected to the top plate 30, and the other end of the buffer spring 31 is connected to the bottom plate 29. The bottom plate 29 is installed on the side wall of the cylinder 1 and is inclined upward.

[0045] The base plate 29 is mounted on the extension frame 24 on the cylinder 1. The base plate 29 is provided with a lower sleeve 32 that is sleeved around the buffer spring 31. The top plate 30 is provided with an upper sleeve 33 that is sleeved around the buffer spring 31. The lower sleeve 32 is slidably mounted inside the upper sleeve 33.

[0046] When the venting pipe needs to be opened, the retraction of the movable end of the hydraulic cylinder 9 drives the tilting arm 4 to rotate around the hinge shaft 11. At the same time, with the cooperation of the linkage mechanism, the cover plate 2 is lifted a certain distance before being tilted, so as to avoid wear between the cover plate 2 and the cylinder 1 when it is tilted, thereby opening the venting pipe to discharge the exhaust gas.

[0047] At the same time, after the tilting arm 4 tilts to a certain angle, it comes into contact with the buffer mechanism and slowly stops rotating under the action of the buffer mechanism to avoid the tilting arm 4 hitting the cylinder and causing damage to the cylinder.

[0048] When venting is not required, the movable end of the hydraulic cylinder 9 extends and pushes upward against the tilting arm 4 to prevent the tilting arm 4 from rotating under the weight of the counterweight block 5, so that the cover plate 2 covers the cylinder 1 and seals the venting pipe.

[0049] This utility model features an integrally molded cover plate, which solves the problem of split-type pipe covers being easily damaged by exhaust gas impact due to gaps in the center of the cover. When the flipping mechanism drives the cover plate to rotate, a linkage mechanism is set up so that when the flipping mechanism drives the cover plate to rotate, it can first lift the cover plate a certain distance away from the cylinder before flipping it, avoiding wear at the contact point between the cover plate and the cylinder. At the same time, refractory fiber blocks are set inside the cover plate, which can prevent the cover plate from being damaged by high temperature impact and improve the service life of the cover plate.

[0050] This invention also incorporates a buffer mechanism, which allows the tilting arm to gradually stabilize when it reaches its limit, preventing it from directly impacting the cylinder and damaging the venting pipe when it tilts downwards, thus improving operational safety.

[0051] Because the cover plate, cylinder, tilting mechanism, and drive mechanism are integrated into one unit, the venting pipe can be opened quickly, improving operational efficiency. At the same time, no manual operation is required to open the venting pipe, avoiding high-temperature damage to the human body caused by the high-temperature exhaust gas when the venting pipe is opened, thus ensuring the safety of the equipment during operation.
