Description

Technical Field

[0001] This utility model belongs to the technical field of coke oven maintenance, and in particular relates to a device for replacing coke oven frames. Background Technology

[0002] The coking process is characterized by the fact that all carbonization chambers are cyclically pushed and charged with coke in a certain sequence. Before and after the coking and charging operation, the furnace door needs to be removed and hung. During this process, the coke oven frame will be subjected to impact stress. At the same time, due to the influence of various factors such as the material of the furnace frame, changes in coking time, furnace body expansion and weather changes, the furnace frame may be damaged and need to be replaced during use.

[0003] Currently, replacing an old furnace frame requires preparing an empty furnace door, welding it to the old frame, using the empty furnace door to remove the old frame, separating the old frame from the empty furnace door, welding the new furnace frame to the empty furnace door, installing the new frame using the empty furnace door again, and then separating the new frame from the empty furnace door to complete the replacement. This process involves repeatedly welding and disconnecting the empty furnace door from the old and new furnace frames, resulting in high temperatures in the work area, a high risk of burns to employees, long working hours, and a significant workload. Utility Model Content

[0037] Currently, before replacing the old furnace frame 3, a spare furnace door lining brick needs to be removed to create an empty furnace door. When replacing the furnace frame 3, the empty furnace door is placed on the furnace frame 3 to be replaced, and the empty furnace door is welded and fixed to the furnace frame 3 using channel steel. A door retrieval machine is then used to remove both together. After removal, the door retrieval machine is moved to the furnace door station, the furnace frame 3 is fixed on the fixing frame, the welded position between the empty furnace door and the furnace frame 3 is disconnected, and then the empty furnace door is welded and fixed to the new furnace frame 3. A large trolley door retrieval machine is used to replace both together in place. After the new furnace frame 3 is fixed to the corresponding carbonization chamber protection plate, the welded position between the empty furnace door and the new furnace frame 3 is disconnected, and the replacement is complete. The entire replacement process requires the removal of a furnace door lining brick in the preliminary preparation work, which not only takes a long time but also wastes a set of furnace door bricks. During the replacement process, the connection between the empty furnace door and the old and new furnace frames 3 needs to be repeatedly welded and disconnected. The working area has a high temperature, which can easily cause burns to employees. The work time is long and the workload is large.

[0038] To address the aforementioned technical problems, this utility model provides a device for replacing a coke oven frame. The frame 3 is a rectangular frame placed vertically. A first large hook 31 and a second large hook 32 are respectively provided at the upper and lower ends of the frame 3. Figure 4 As shown.

[0039] like Figures 1 to 3 and Figure 5 As shown, the device in this embodiment mainly includes two parts: a first component 1 and a second component 2.

[0040] The first component 1 is detachably connected to the first large hook 31 and the second large hook 32, respectively.

[0041] The second component 2 is located below the first large hook 31 and the second large hook 32, and abuts against the bottom of the two large hooks. The second component 2 is mainly used to support the two large hooks.

[0042] The second component 2 is fixedly connected to the first component 1 to fix the device on the two large hooks. The large hooks of the gate hoist can hook the second component 2 and use the device to move the furnace frame 3 from the coke oven protection plate and lift the furnace frame 3.

[0043] The trolley door retrieval crane aligns with the furnace frame 3. After the large hook of the retrieval crane engages with the second component 2, the connecting hook bolts between the furnace frame 3 and the coke oven protection plate are removed. The retrieval crane then moves forward and backward, thereby removing the furnace frame 3. This device supports the entire furnace frame 3 via the second component 2. After the old furnace frame 3 is removed, the device is detached from the old furnace frame 3 and fixed to the two large hooks of the new furnace frame 3. Finally, the retrieval crane installs the new furnace frame 3 onto the coke oven protection plate, and then the device is removed.

[0044] The device in this embodiment can be directly fixed to two large hooks on the furnace door frame. A first component 1 is detachably connected to each of the two large hooks, and a second component 2 supports the two large hooks. After the large hooks of the door-removing machine hook onto the second component 2, the furnace frame 3 is removed from the coke oven protection plate. The device then supports the entire furnace frame 3, allowing for direct removal of the furnace door frame. Because the second component 2 supports the two large hooks, the furnace door frame will not fall off. Compared to traditional replacement methods, this device eliminates the need for an empty furnace door, thus saving the welding process and improving the efficiency of disassembly and assembly of the furnace frame 3.

[0045] Typically, the first large hook 31 and the second large hook 32 on the furnace frame 3 extend forward, and the ends of the two large hooks are respectively provided with slots 33 for installing the furnace door, with the tops of the slots 33 open. In some embodiments, the first component 1 can be directly engaged in the slots 33 of the two large hooks, see... Figure 5As shown, this allows for a detachable connection between the first component 1 and the two large hooks. By having the first component 1 engage with the slots 33 of the two large hooks, separation of the first component 1 from the two large hooks can be prevented when the second component 2 supports the entire furnace frame 3.

[0046] Of course, in other embodiments, the first component 1 and the two large hooks can also be connected in other ways to achieve a detachable connection, such as bolt connection.

[0047] In some embodiments, the first component 1 includes a first crossbeam 11, the two ends of which can span across two large hooks. The first end of the first crossbeam 11 is engaged in the slot 33 of the first large hook 31, and the second end of the first crossbeam 11 is engaged in the slot 33 of the second large hook 32.

[0048] The shape of the first crossbeam 11 is not specifically limited; for example, such as... Figure 1 and Figure 2 As shown, when the slot 33 of the first large hook 31 is opposite to the slot 33 on the second large hook 32, the first crossbeam 11 can be a straight beam or a frame structure.

[0049] Furthermore, the second component 2 includes a second crossbeam 21, the first end of which has a first support portion supporting the first large hook 31, and the second end of which has a second support portion supporting the second large hook 32. The door retrieval machine can hook the second crossbeam 21 to drag the entire device.

[0050] The first crossbeam 11 and the second crossbeam 21 can be either seamless steel pipe structures or solid shaft structures, respectively.

[0051] The first crossbeam 11 and the second crossbeam 21 can be detachably connected. First, the first crossbeam 11 can be secured in the slots 33 of the two large hooks. Then, the second crossbeam 21 can be placed at the bottom of the two large hooks and connected to the first crossbeam 11. After connecting the replaced furnace door frame to the protective plate on the coke oven, the first crossbeam 11 and the second crossbeam 21 can be separated before installing the furnace door. This device should be installed on the furnace door frame before disassembling it.

[0052] For example, such as Figure 2 and Figure 3 As shown, the first crossbeam 11 has a first connecting plate 12 at both ends, and the second crossbeam 21 has a second connecting plate 22 at both ends. The two connecting plates are perpendicular to the corresponding crossbeams, and the two connecting plates are respectively provided with connecting holes. When the support parts at both ends of the second crossbeam 21 abut against the two large hooks, the connecting holes of the two connecting plates are joined together. The two stiffening plates can be connected by passing bolts through the connecting holes of the two connecting plates, thereby realizing the connection of the two crossbeams.

[0053] As for the shape of the first connecting plate 12 and the shape of the second connecting plate 22, this application embodiment does not make specific limitations. The shapes of the two connecting plates can be triangles or rectangles, etc.

[0054] Of course, in other embodiments, the two connecting plates can also be connected in other ways, such as by snap-fitting.

[0055] In some other embodiments, the first crossbeam 11 and the second crossbeam 21 can be pre-installed together, and when the first crossbeam 11 is locked in the slots 33 of the two large hooks, the second crossbeam 21 is exactly abutting against the bottom of the two large hooks.

[0056] like Figure 3 As shown, in some embodiments, the first support and the second support respectively include a bracket plate 24 disposed on the second connecting plate 22. The bracket plate 24 is a T-shaped plate, including a horizontally disposed first support plate 241 and a vertically disposed second support plate 242. The entire T-shaped plate is perpendicular to the second connecting plate 22. The first support plate 241 in the bracket plate 24 is used to support the two large hooks of the furnace frame 3.

[0057] The bracket plate 24 can be directly welded and fixed to the second connecting plate 22, and is located on the outside of the second connecting plate 22, that is, on the side away from the second crossbeam 21.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments, the bottom of the first connecting plate 12 has a first rib portion 13 formed by bending, and the bottom of the second connecting plate 22 has a second rib portion 23 formed by bending. The first rib portion 13 and the second rib portion 23 each have a connecting hole.

[0059] When the support parts at both ends of the second crossbeam 21 abut against the bottom of the two large hooks respectively, the first stiffener 13 of the first connecting plate 12 fits against the second stiffener 23 of the second connecting plate 22, and the connecting holes on the two stiffeners are coaxial. At this time, the bolts pass through the connecting holes on the two stiffeners respectively to connect the first connecting plate 12 and the second connecting plate 22, thereby fixing the first component 1 and the second component 2 together.

[0060] When the first crossbeam 11 is a circular tube, to prevent the first crossbeam 11 from being placed on the two large hooks and rotating, thus affecting the docking of the two connecting plates, such as... Figure 2 As shown, in some embodiments, the first connecting plates 12 at both ends of the first crossbeam 11 are provided with hooks 14.

[0061] The hooks 1 on the two first connecting plates 12 are used to hang on the corresponding large hooks, namely the first hook 31 and the second hook 32. When the two hooks 14 are hung on the corresponding large hooks respectively, the connecting holes of the first connecting plate 12 and the connecting holes of the second connecting plate 22 are coaxial, which makes it convenient for the operator to connect the two connecting plates.

[0062] like Figure 2 As shown, in some embodiments, the first component 1 may further include a balance beam 15, which is used to connect the first connecting plates 12 at both ends of the first crossbeam 11.

[0063] The balance beam 15 can be parallel to the first crossbeam 11. Both ends of the balance beam 15 can be welded to the corresponding connecting plates respectively. The balance beam 15 can ensure the overall stability of the first component 1.

[0064] like Figure 2 As shown, in some embodiments, the first component 1 may further include a pressing member 16, which is disposed on the first crossbeam 11. The door retrieval machine is provided with a telescopic cylinder opposite to the pressing member 16. The piston rod end of the telescopic cylinder is opposite to the pressing member 16. When the piston rod of the telescopic cylinder extends, the end of the piston rod abuts against the pressing member 16. The direction of the force applied by the piston rod of the telescopic cylinder to the pressing member 16 is perpendicular to the first crossbeam 11. Since the first crossbeam 11 is stuck in the slots 33 of the two large hooks, the pressure applied to the pressing member 16 by the telescopic cylinder can ensure the overall stability of the door retrieval machine.

[0065] The shape of the pressing member 16 is not specifically limited. For example, as shown... Figure 2 As shown, the top pressure member 16 is cylindrical in shape and can be directly welded to the first crossbeam 11 and to the middle part of the first crossbeam 11.

[0066] In some embodiments, a buffer pad can be provided at the free end of the top pressing member 16, and the piston rod of the telescopic cylinder directly presses against the buffer pad to achieve the function of buffering and shock absorption.

[0067] like Figure 4 As shown, in some embodiments, the depth of the slot 33 of the first large hook 31 and the depth of the slot 33 of the second large hook 32 are greater than or equal to the height of the first crossbeam 11.

[0068] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
