Description

Technical Field

[0001] This utility model belongs to the technical field of anode plate installation tools for combined electrostatic precipitators, specifically relating to a special tool for hoisting anode plates of combined electrostatic precipitators. Background Technology

[0002] In industrial production, electrostatic precipitators are key equipment for controlling dust emissions, and the installation quality of their anode plates directly affects dust removal efficiency and equipment operational stability. Anode plates are usually made of thin rolled steel plates, which have poor rigidity and are easily deformed. During hoisting and transportation, uneven stress or collisions can easily cause defects such as bending and wrinkling, leading to excessive deviations in the spacing between the anode plates during subsequent installation. In severe cases, they may even need to be scrapped, significantly increasing construction costs and time.

[0003] Currently, the industry mostly uses traditional sling binding or simple frame assistance for hoisting anode plates of electrostatic precipitators. Traditional sling binding requires manual fixing of each plate, which is not only cumbersome, but also typically only allows for 6-9 plates to be hoisted at a time, limiting the daily hoisting capacity to 150-225 plates, resulting in low efficiency.

[0004] Meanwhile, the contact point between the sling and the electrode plate is prone to local stress concentration. In addition, the lack of lateral restraint during hoisting often leads to deformation of the electrode plates due to swaying and collision.

[0005] To address this issue, a special tool for hoisting the anode plates of a combined electrostatic precipitator is provided. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a special tool for hoisting anode plates of a combined electrostatic precipitator, which solves the problems of low hoisting efficiency and easy damage and deformation of anode plates in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A specialized tool for hoisting anode plates in a combined electrostatic precipitator includes a main lifting rod and an auxiliary tray. The main lifting rod and the auxiliary tray work together to smoothly lift the anode plates to be installed. Two lifting lugs A are symmetrically fixed on one side of the main lifting rod, and the lifting lugs A are used to connect to an external first lifting device. Multiple hanging components are fixedly installed on the side of the main lifting rod opposite to the lifting lugs A, and the hanging components are used to connect to the anode plates to be installed via external steel wire ropes. Two lifting lugs B are provided at both ends of the auxiliary tray, and the lifting lugs B are used to connect to an external second lifting device via external lifting steel wires. The auxiliary tray is provided with multiple sets of limiting stops, which are used to prevent multiple anode plates to be installed from colliding and deforming with each other during the lifting process.

[0009] In the above technical solution, the auxiliary tray includes two side steels, at least four I-beams are fixedly installed between the two side steels, and at least four extension rods are provided on the opposite side of the two side steels. The extension rods are arranged parallel to the outside of the corresponding I-beams, and multiple sets of limiting stops are fixedly arranged at equal intervals on the upper surfaces of the corresponding I-beams and extension rods.

[0010] In the above technical solution, each group of limiting stops consists of two angle steel pieces, and the two angle steel pieces in the same group are arranged facing away from each other.

[0011] In the above technical solution, a channel steel is fixedly installed between the upper surfaces of the I-beam on the left and the two extension rods on the left, and a bottom support steel plate is fixedly installed on the right surface of the channel steel.

[0012] In the above technical solution, an upper diagonal brace and a lower diagonal brace are fixedly installed between the two side steels.

[0013] This utility model provides a special tool for hoisting the anode plates of a combined electrostatic precipitator. Compared with the prior art, the advantages are as follows:

[0014] This invention utilizes a collaborative structure between a main lifting rod and an auxiliary tray. The main lifting rod's hanging components enable the subsequent vertical lifting of multiple anode plates. The limiting stops on the auxiliary tray provide lateral restraint to the anode plates, effectively preventing collision and deformation issues caused by lack of restraint in traditional lifting methods. The supporting steel plate and the coordinated operation of the main and auxiliary lifting tools ensure vertical stability during anode plate lifting, resolving the localized stress concentration problem inherent in traditional sling binding methods. Furthermore, the high-strength auxiliary tray structure composed of side steel and I-beams enables the lifting of up to 42 anode plates at a time, significantly improving lifting efficiency compared to the traditional 6-9 plates, and substantially reducing construction costs and time constraints.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:

[0023] A special tool for hoisting anode plates of a combined electrostatic precipitator includes a main lifting rod 1 and an auxiliary tray 2. The main lifting rod 1 and the auxiliary tray 2 are used together to smoothly lift the anode plate to be installed. Two lifting lugs A11 are symmetrically welded to one side of the main lifting rod 1. The lifting lugs A11 are used to connect to an external first lifting device. Multiple hanging parts 12 are fixedly installed on the side of the main lifting rod 1 opposite to the lifting lugs A11. Figure 2 (a hollow welded component in a triangular shape), the hanging component 12 is used to install an external steel wire rope between itself and the anode plate of the combined electrostatic precipitator to be installed;

[0024] The auxiliary tray 2 has two lifting lugs B211 welded and fixedly installed at its left and right ends. The lifting lugs B211 are used to connect to an external second lifting device via an external lifting wire. The auxiliary tray 2 is equipped with multiple sets of limiting stops 24. The limiting stops 24 are used to block multiple combined electrostatic precipitator anode plates during the lifting process to prevent adjacent combined electrostatic precipitator anode plates from colliding and deforming during the lifting process, which would affect the construction quality.

[0025] It should be noted that, in combination Figure 1 , Figure 3 and Figure 4As shown, the auxiliary tray 2 includes two side steels 21, and at least four I-beams 22 are fixedly installed between the two side steels 21. At least four extension rods 23 are welded and installed on the opposite sides of the two side steels 21. The extension rods 23 are arranged parallel to the outside of the corresponding I-beams 22. Multiple sets of limiting stops 24 are equidistantly arranged on the upper surfaces of the corresponding I-beams 22 and extension rods 23 by welding.

[0026] like Figure 3 As shown, each set of limit stops 24 consists of two angle steel pieces, and the two angle steel pieces in the same set are arranged facing away from each other.

[0027] Combination Figure 1 , Figure 3 and Figure 4 As shown, a channel steel 3 is welded and fixedly installed between the upper surfaces of the I-beam 22 on the left and the two extension rods 23 on the left. A bottom support steel plate 4 is welded and fixedly installed on the right surface of the channel steel 3. When lifting multiple combined electrostatic precipitator anode plates, the bottom support steel plate 4 can be used to support them to ensure that they are lifted steadily and vertically.

[0028] Finally, to ensure the overall structural strength of the auxiliary pallet 2, the upper diagonal brace 5 and the lower diagonal brace 6 are welded and fixed between the two side steels 21 to enhance the overall stability and rigidity, prevent the side steels 21 from bending or twisting during the hoisting operation, and thus ensure the safety and reliability of the anode plate hoisting process.

[0029] The dimensions of the side steel 21, I-beam 22, outer edge rod 23, angle steel, channel steel 5, and bottom support steel plate 4 used in this special lifting tool can be adaptively adjusted according to the dimensions of the anode plate of the combined electrostatic precipitator during the actual manufacturing process to meet the lifting needs of cathode plates of different sizes.

[0030] In operation, the anode plates of the combined electrostatic precipitator are first positioned by horizontally embedding them into the limiting stops 24. Then, the main lifting rod 1 is placed on the side steel bars 21, aligning it with the hanging bracket 12. Subsequently, external steel wire ropes are threaded through the hanging bracket 12 and locked to the corresponding anode plates. Vertical lifting is then performed by connecting the lifting lug A11 of the main lifting rod 1 to the steel wire rope of an external 20t horizontal boom crane. Simultaneously, an external 25t truck crane is used to coordinate the lifting with external steel wire ropes connected via the lifting lug B211 of the auxiliary pallet 2. This process, through the coordinated operation of the main and auxiliary lifting tools and the lateral constraint of the limiting stops on the anode plates, effectively prevents deformation of the anode plates during lifting, thus ensuring installation quality.

[0031] Through on-site testing and comparative analysis, other hoisting methods can lift 6 to 9 anode plates at a time, with 25 hoisting operations per day, equivalent to a daily lifting volume of approximately 150 to 225 plates. However, using this specialized hoisting tool, up to 42 plates can be lifted at once, with 25 hoisting operations per day, resulting in a lifting volume of up to 1050 plates. Therefore, this new tool not only ensures that the anode plates do not deform during hoisting but also significantly improves hoisting efficiency.
