[0001] The utility model relates to the technical field of roof-lifting and renovation protection for a coke oven combustion chamber, in particular to a mobile protection device for roof-lifting and renovation of a coke oven combustion chamber. Background Art

[0002] Coke ovens are mainly composed of refractory silica bricks. During the coke oven production process, the furnace wall will be damaged by erosion, perforation, etc. In severe cases, the heating fire channel will be blocked, making it difficult to push coke, and coal cannot be loaded and coke cannot be discharged normally. The roof-lifting and renovation technology must be used to rebuild the damaged furnace wall. Due to the characteristics of coke oven silica bricks, they cannot be exposed to rain, otherwise the service life of the rebuilt furnace wall will be greatly shortened. Therefore, rain protection measures must be taken during the roof-lifting and renovation, and refractory bricks are strictly prohibited from being soaked in rain. The existing rain protection method for the roof-lifting of coke oven channels is to use steel pipes to build a canopy on the furnace roof to prevent rain. This structure is only suitable for the roof-lifting and renovation of up to 2-3 combustion chamber channels in a row. The built canopy steel pipes are placed directly on the furnace roof, which affects the production and construction of coke ovens and has certain safety hazards.

[0003] In view of this, the existing technology should be improved to solve the above-mentioned technical problems existing in the existing technology. Utility Model Content

It should be noted that unless otherwise specifically stated, the relative arrangement of the parts and steps, the composition of the materials, the numerical expressions and the numerical values ​​described in these embodiments should be interpreted as merely exemplary, rather than as limiting.

[0030] It should be noted that, in the description of the present invention, unless otherwise specified, the meaning of "multiple" is greater than or equal to two; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0031] It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. When a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device.

[0032] All terms used in the present invention have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0033] Technologies, methods, and apparatus known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, these technologies, methods, and apparatus should be considered part of the specification.

[0034] like Figure 1 As shown, the utility model provides a mobile protective device for the roof removal and renovation of the coke oven combustion chamber, which includes: a supporting carriage 1, the supporting carriage 1 is vertically arranged in the coke oven roof removal and renovation area 2, and the supporting carriage 1 can be movably installed on the coal loading car track 3; a protective shed fixed truss 4, the protective shed fixed truss 4 is a shed with a pointed roof, and is fixedly arranged above the supporting carriage 1, the cross-section of the protective shed fixed truss 4 in the vertical direction is an isosceles triangle, and the bottom side of the protective shed fixed truss 4 is parallel to the upper surface of the coke oven; a color steel tile 6, the color steel tile 6 is laid above the protective shed fixed truss 4 along the extension direction of the waist of the isosceles triangle.

[0035] like Figure 2 As shown, it can be seen from the top view that both sides of the coke oven roof removal and renovation area are coke oven production areas. In order to ensure normal operation and heat dissipation in the production area, the device needs to be moved.

[0036] like Figure 3As shown, in some specific embodiments, the length of the color steel tile 6 is greater than the length of the waist of the isosceles triangle. The length of the color steel tile 6 can exceed the length of the waist of the isosceles triangle truss, which means that the color steel tile 6 will have more overlapping parts at the connection between the trusses. This overlap helps to enhance the sealing of the roof and reduce the risk of rainwater penetration, thereby improving its waterproof performance. However, in order to ensure the strength and stability of the color steel tile 6, although the length of the color steel tile 6 can exceed the truss, it is also necessary to ensure that its strength and stability meet the requirements. Too long color steel tile 6 may increase its own weight and deformation risk. Preferably, the laying length of the color steel tile 6 selected in this application is 700mm longer than the length of the waist on one side of the isosceles triangle truss. The thickness of the color steel tile 6 is 0.75mm and is made of 100mm channel steel.

[0037] On the basis of the above embodiment, a plurality of support beams 7 are vertically arranged on the bottom edge of the fixed truss 4 of the protective shed, and the intervals between the support beams 7 are 1m. The fixed truss 4 of the protective shed is prone to lateral instability under load. By providing the support beams 7, additional lateral support can be provided for the truss, thereby enhancing its lateral stability and making the structure safer and more stable. The support beams 7 arranged at intervals can improve the rigidity and stability of the truss, make the load in the truss structure more evenly distributed and transferred, avoid the load being concentrated in a certain area, thereby improving the bearing capacity and stability of the entire structure. In the present application, the interval of 1m is more appropriate.

[0038] In some specific embodiments, the base angle of the isosceles triangle is 15°. The isosceles triangle truss has higher structural stability. The structural stability of the triangle is higher than that of other shapes, and the isosceles triangle further enhances its stability because its two sides are equal. This stability enables the isosceles triangle truss to better resist external loads and deformation. When the base angle of the isosceles triangle truss is set to 15°, its top vertex is relatively closer to the midpoint of the base. This design can improve the structural rigidity of the truss. At this time, the bottom rod is subjected to greater axial pressure, while the top rod is subjected to greater axial tension. This force distribution method helps to make full use of the mechanical properties of the material and improve its bearing capacity. The truss arranged in this way occupies relatively less space in the horizontal direction, which can reduce the overall height of the coke oven and has low requirements for space height.

[0039] On the basis of the above embodiments, the width of the projection of the color steel tile 6 on the horizontal plane is the same as the length of the maintenance coke oven carbonization chamber 5 from the machine side to the coke side. The length of the maintenance coke oven carbonization chamber 5 from the machine side to the coke side is the entire coke oven roof renovation area 2. In the process of laying the color steel tile 6, using a sufficiently long color steel tile 6 can reduce the number of seams generated during the construction process. Seams are common parts in the installation of color steel tiles 6 and are also potential risk points for water leakage. Therefore, reducing the number of seams can improve the sealing and waterproof performance of the roof and reduce the risk of water leakage. At the same time, it can also reduce the structural weaknesses caused by too many seams. Each seam is a potential stress concentration point, and too many seams will reduce the stability of the entire structure. A color steel tile 6 of sufficient length can also ensure that the area of ​​the maintenance coke oven carbonization chamber 5 from the machine side to the coke side can be fully covered, so that the rain protection effect is better.

[0040] In some specific embodiments, the length of the projection of the color steel tile 6 on the horizontal plane is 5 to 7 times the center distance of the maintenance coke oven carbonization chamber 5. The currently used maintenance coke oven carbonization chamber 5 is divided into two structures: five holes and seven holes. The center distance refers to the distance between the holes. 5 to 7 times the center distance of the maintenance coke oven carbonization chamber 5 is the total length of the maintenance coke oven carbonization chamber 5, that is, when the length of the projection of the color steel tile 6 on the horizontal plane is 5 to 7 times the center distance of the maintenance coke oven carbonization chamber 5, it covers the entire maintenance coke oven carbonization chamber 5. Thereby, it has a significant beneficial effect in waterproofing, can reduce the risk of water leakage, improve the integrity of the waterproof layer, simplify the waterproofing process and enhance durability. These advantages make the device have a wide range of application prospects in the waterproofing work of the coke oven roof renovation area 2.

[0041] like Figure 5 As shown, on the basis of the above embodiment, a pedestrian safety passage is provided in the middle of the supporting running frame 1, and no supporting beam 7 is provided. Originally, the supporting beam 7 is provided at intervals of 1m. In order to ensure the safety of pedestrians, a hollow area is reserved in the middle, and the hollow area is a pedestrian safety passage, and no supporting beam 7 is provided. Below the working area of ​​the device is an anxious roof-lifting renovation area. In order to ensure the normal progress of the renovation work, the operator needs to work below. By providing a pedestrian safety passage in the middle, it can be ensured that the operator maintains a safe distance from the supporting running frame 1 and the equipment or materials thereon during walking and working, and avoid safety accidents such as collision or falling. The provision of the central pedestrian safety passage allows the operator to easily reach various parts of the supporting running frame 1, whether for equipment inspection, maintenance or construction operation, it is more convenient to reach the target position and improve work efficiency. For some equipment or maintenance materials that need to be transported to the supporting running frame 1, the central pedestrian safety passage can be used as a convenient transportation passage, which is convenient for the operator to transport the items to the designated location and reduce the safety hazards and labor intensity during the handling process. Preferably, the width of the pedestrian safety passage is 1.5 to 2 m.

[0042] like Figure 4 As shown, in some specific embodiments, the support running frame 1 is in the shape of a rectangular parallelepiped and is made of channel steel. The support running frame 1 is a rectangular parallelepiped structure with a hollow interior. Since its four side surfaces and the top and bottom surfaces are all flat, it has excellent stability when bearing loads in the vertical and horizontal directions. The structural characteristics of the rectangular parallelepiped enable it to evenly distribute and transfer loads, thereby improving the load-bearing capacity of the support running frame 1. Its bottom area is large, which can effectively disperse the pressure and reduce the pressure per unit area, so that the support running frame 1 can still remain stable when bearing a large load. The rectangular parallelepiped support running frame 1 has a simple shape and is easy to manufacture by machining or mold forming. At the same time, its standardized size and shape also make the installation process simpler and faster, and improve work efficiency.

[0043] like Figure 5 As shown, on the basis of the above embodiment, a plurality of vertical reinforcing ribs 8 and diagonal reinforcing ribs 9 are arranged at intervals on the supporting running frame 1. The addition of the vertical reinforcing ribs 8 and the diagonal reinforcing ribs 9 can significantly improve the overall structural stability of the supporting running frame 1. These reinforcing ribs can effectively resist external loads and deformations, so that the supporting running frame 1 maintains its shape and position unchanged when subjected to various forces, thereby ensuring the stability and safety of the supporting running frame 1. The design of the reinforcing ribs can optimize the stress distribution inside the supporting running frame 1, so that the supporting running frame 1 can transmit force more evenly when bearing loads. Preferably, the vertical reinforcing ribs 8 are arranged at intervals of 1m.

[0044] On the basis of the above embodiments, a running wheel 10 is fixedly provided at the bottom of the supporting running frame 1 for reciprocating motion on the coal loading car track 3. The addition of the running wheel 10 enables the supporting running frame 1 to have the ability to move, thereby greatly improving its maneuverability and flexibility. The supporting running frame 1 with the running wheel 10 at the bottom can be easily carried and installed by manpower or small equipment, which greatly reduces the difficulty and cost of carrying and installation. When the combustion chamber channel is uncovered and renovated, if a traditional fixed support frame is used, it may be necessary to frequently disassemble and reinstall, which not only increases the workload, but also may pose a safety hazard. The support frame with the running wheel 10 at the bottom can be easily moved, reducing the number of disassembly and reinstallation times, thereby improving safety. Preferably, three evenly arranged running wheels 10 are provided at the bottom of one side of the supporting running frame 1.

[0045] In some specific embodiments, the supporting running frame 1 is fixedly connected to the fixed truss 4 of the protective shed by welding, and each coal loading car track 3 is slidably connected to the supporting running frame 1 .

[0046] The mobile protection device of the utility model ensures rain protection when the coke carbonization chamber is uncovered and renovated by setting color steel tiles 6 and protective shed fixed trusses 4. The device can be placed on the coal loading car track 3 for movement. When production needs it, it can be moved away without affecting the production of other coke oven carbonization chambers. A pedestrian passage is designed in the middle of the device to ensure the safety of the operators. After the device is applied, the on-site use effect is good.
