Description

Technical Field

[0001] The utility model relates to the technical field of maintenance inside a cooking tower, in particular to a cooking tower maintenance device. Background Art

[0002] Chemical pulping workshops must regularly inspect and repair the sieve plates on the inner wall of the cooking tower, and a scaffolding work platform needs to be set up inside the tower. Since the space inside the cooking tower is a cylindrical space, the working height difference is large, and a lot of construction time is required in the process of setting up the coupler scaffolding. Coupler scaffolding is used to set up the circular working platform inside the cooking tower. The first basic support pole of the coupler scaffolding is set up on the arc platform at the bottom of the cooking tower and cannot obtain good vertical support. When the coupler scaffolding is built upward from the arc platform at the bottom of the cooking tower to reach the required maintenance height of 25 meters, the larger deadweight of the coupler scaffolding plus the weight of the workers can easily cause the scaffolding to collapse as a whole. The coupler scaffolding and its connecting fasteners are made of cast iron, and the connection nodes are fastened with fasteners and bolts. The foot pedals are a single rectangle, so there are greater safety risks during construction and use.

[0003] Currently, the fasteners and pipe fittings in the coupler-type scaffolding are made of cast iron, which is heavy and not corrosion-resistant. It is not only inconvenient for workers to carry them, but the cast iron parts will be corroded by the black liquid dripping from the tower. In addition, the joints of the coupler-type scaffolding structure are fastened with fasteners and bolts. Workers need to tighten the bolts one by one, resulting in a long installation and disassembly time. The foot pedals of the coupler-type scaffolding are of a single shape and are spliced ​​into a flat circular working platform that fits the inner wall of the tower. This results in low utilization of the space inside the tower during the construction process, resulting in a large gap between the guardrail and the inner wall, and the workers are in an unsafe working environment.

[0004] Therefore, how to solve the problems of unstable support, inconvenient disassembly and workers being exposed in an unsafe working environment in the existing cooking tower maintenance device is one of the important issues that need to be solved urgently in this field. Utility Model Content

[0012] According to the cooking tower maintenance device of one aspect of the present invention, along the axial direction of the cooking tower, the axial height H of each guardrail is ≥1.5m.

[0013] According to the cooking tower maintenance device in one aspect of the present invention, the second support assembly is an aluminum-magnesium alloy second support assembly.

[0014] According to the cooking tower maintenance device of one aspect of the present invention, each vertical pole is a disc-type vertical pole.

[0030] Chemical pulping workshops must regularly inspect and repair the sieve plates on the inner wall of the cooking tower, and a scaffolding work platform needs to be set up inside the tower. Since the space inside the cooking tower is a cylindrical space, the working height difference is large, and a lot of construction time is required in the process of setting up the coupler scaffolding. Coupler scaffolding is used to set up the circular working platform inside the cooking tower. The first basic support pole of the coupler scaffolding is set up on the arc platform at the bottom of the cooking tower and cannot obtain good vertical support. When the coupler scaffolding is built upward from the arc platform at the bottom of the cooking tower to reach the required maintenance height of 25 meters, the larger deadweight of the coupler scaffolding plus the weight of the workers can easily cause the scaffolding to collapse as a whole. The coupler scaffolding and its connecting fasteners are made of cast iron, and the connection nodes are fastened with fasteners and bolts. The foot pedals are a single rectangle, so there are greater safety risks during construction and use.

[0031] Currently, the fasteners and pipe fittings in the coupler-type scaffolding are made of cast iron, which is heavy and not corrosion-resistant. It is not only inconvenient for workers to carry them, but the cast iron parts will be corroded by the black liquid dripping from the tower. In addition, the joints of the coupler-type scaffolding structure are fastened with fasteners and bolts. Workers need to tighten the bolts one by one, resulting in a long installation and disassembly time. The foot pedals of the coupler-type scaffolding are of a single shape and are spliced ​​into a flat circular working platform that fits the inner wall of the tower. This results in low utilization of the space inside the tower during the construction process, resulting in a large gap between the guardrail and the inner wall, and the workers are in an unsafe working environment.

[0032] In response to the above problems, an exemplary embodiment of the present invention provides a cooking tower maintenance device to solve the problems of unstable support, inconvenient disassembly, and workers being exposed in an unsafe working environment in the cooking tower maintenance device in the prior art.

[0033] A cooking tower maintenance device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Figure 1 The figure shows the overall structure of the maintenance device for the cooking tower 6 according to the embodiment of the present invention. Figure 1As shown, a cooking tower 6 maintenance device is applied to the cooking tower 6. The cooking tower 6 maintenance device includes: a first support assembly 1 and a second support assembly 2 fixed on the first support assembly 1. The first support assembly is located in the middle of the cooking tower. It should be understood that the midpoint along the height direction of the cooking tower is the middle of the cooking tower, which can reduce the overall height of the cooking tower maintenance device. The first support assembly 1 includes: multiple first support rods 11, multiple first support plates 12 and multiple limit members 13, each first support rod 11 extends into the cooking tower 6 through the manhole door 5 of the cooking tower 6, each first support plate 12 is distributed in an array, and each limit member 13 is used to fix each first support plate 12 on each first support rod 11; the second support assembly 2 includes: multiple vertical rods 22, multiple horizontal rods 21, multiple diagonal rods 23 and multiple connecting members, each vertical rod 22, each horizontal rod 21 and each diagonal rod 23 constitutes a modular component through each connecting member, and each modular component is connected to each other through each connecting member to form an inspection frame, and a plurality of inspection platforms 3 are also provided on the inspection frame, each inspection platform 3 is close to the inner wall of the cooking tower 6, and each inspection platform 3 is used to support staff for maintenance and protection.

[0035] In practical applications, Figure 2 FIG is a top view of the first support assembly 1 according to an embodiment of the present utility model. Figure 1 - Figure 2 As shown, each first support rod 11 extends into and passes through the cooking tower 6 through the manhole door 5 of the cooking tower 6. Six cross beams are actually inserted at the manhole door 5 in the cooking tower 6. The cross beams serve as the main support of the entire operating system. Each first support plate 12 is distributed in an array. It should be understood that each of the above-mentioned first support plates 12 is perpendicular to each first support rod 11, and the radial dimensions of each first support plate along the radial direction of the cooking tower 6 are the same. Each limiting member 13 is used to fix each first support plate 12 on each first support rod 11 to avoid slippage between the first support plate 12 and the first support rod 11. It should be understood that the limiting member 13 can be a limiting lock plate, a hinge, etc., which are not listed here one by one. When the limiting member 13 is a limiting locking plate, the displacement of two adjacent first support plates 12 is limited by their own geometric boundaries. Each first support plate 12 is provided with a limiting locking plate that interlocks with the crossbeam, thereby limiting the prying between adjacent first support plates 12. At the same time, the close fit between two adjacent first support plates 12 further limits the displacement between the first support plates 12. In addition, the interconnection between multiple first support plates 12 can provide a larger area of ​​bottom support for the second support assembly 2. The bottom support points of the second support assembly 2 are distributed in an array on the first support assembly 1, improving the structural stability of the entire cooking tower 6 maintenance device, effectively solving the problem of unstable support in the cooking tower maintenance device in the prior art, and at the same time, preventing falling objects and personnel from high altitudes, reducing safety risks.

[0036] like Figure 2 As shown, each first support plate 12 is further provided with a through hole 7 for adjusting each limit member 13. The through hole 7 provided on each first support plate 12 serves as a notch for conveniently moving the limit member 13. The limit member 13 is fixed to the bottom of the platform plate by bolts. The limit member 13 provided on each first support plate 12 is interlocked with the crossbeam.

[0037] like Figure 1 As shown, each vertical rod 22, each horizontal rod 21, and each diagonal rod 23 is connected to form a modular component through each connector, and each modular component is connected to each other through each connector to form an inspection frame. The inspection frame has fewer parts and a simple structure, making installation simpler and faster, saving a lot of construction time. At the same time, the inspection frame has a compact structure, uniform force distribution, good support, higher system stability, and can withstand greater loads. On this basis, the inspection frame is also equipped with multiple inspection platforms 3, each of which is close to the inner wall of the cooking tower 6. The inspection platforms are used to support and protect workers during maintenance. When workers are inspecting the cooking tower, the inspection platforms have a larger load-bearing area, allowing workers to enter as if walking on flat ground without the risk of accidental falls. At the same time, each inspection platform can also receive debris falling from heights, protecting workers, effectively solving the problem of workers being exposed in an unsafe working environment in the prior art.

[0038] like Figure 1 As shown, each maintenance platform 3 is an annular maintenance platform 3 and further includes multiple footrests 24. Each footrest 24 has a hook at each geometric corner. The modular footrests 24 are assembled to form the annular maintenance platform 3. The annular maintenance platform 3 can conform to the inner wall of the tower, forming a flat, circular work platform for convenient maintenance of the sieve plates on the inner wall of the cooking tower 6. The outer side of the annular maintenance platform 3 is in close contact with the inner wall of the cooking tower 6, preventing both falls and excessive tilting of the entire scaffolding. Furthermore, each footrest 24 has a hook at each geometric corner. The footrests 24 are installed in a hanging manner using hooks at the four corners. Under the action of gravity, the footrests 24 can self-lock, thereby fitting tightly to the scaffolding.

[0039] like Figure 1 As shown, each annular inspection platform 3 is also equipped with a guardrail 4. Along the axial direction of the cooking tower 6, each guardrail 4 has an axial height (H) of ≥1.5m. To facilitate movement up and down, a step ladder is installed between the upper and lower annular inspection platforms 3. The step ladder plate is bolted to the inspection frame, ensuring overall stability and reliability. Each annular inspection platform 3 is flanked by protective fences at least 1.5m high, effectively preventing workers from accidentally falling off the platform and providing excellent lateral protection.

[0040] Figure 3 The diagram shows a top view of the cooking tower 6 maintenance device according to an embodiment of the present invention. Figure 3 As shown, the second support assembly is an aluminum-magnesium alloy second support assembly. All second support assemblies 2 are made of aluminum-magnesium alloy material, which can effectively prevent the black liquor dripping from the cooking tower 6 from corroding the second support assembly 2. At the same time, the aluminum-magnesium alloy is lightweight and convenient for workers to carry during the construction process, thereby shortening the construction time. It can be understood that each vertical pole is a disc-type vertical pole, each horizontal pole is a disc-type horizontal pole, and each diagonal pole is a disc-type diagonal pole. The connection points of the vertical poles, the connection points of the horizontal poles, and the connection points of the diagonal poles all adopt disc-type snap-on connections, making the structure of the cooking tower 6 maintenance device stable and reliable. It can be firmly connected with very small external force and the weight of each rod. At the same time, it makes installation simpler and faster, saving a lot of construction time. In order to facilitate up and down activities, a step ladder 8 is installed between the upper and lower maintenance platforms. The step ladder 8 plate is bolted to the maintenance frame, making the overall structure firm and reliable.
