Description

Technical Field

[0001] The utility model relates to the field of waste power generation, in particular to a special rotary maintenance platform for desulfurization atomizers in waste power plants. Background Technique

[0002] With the continuous strengthening of the degree of attention to environmental protection, the state has increased the intensity of treating sulfur dioxide in sintering flue gas, and clearly requires that sintering flue gas must be desulfurized to minimize the impact of sulfur dioxide on the ecological environment. The treatment of sulfur dioxide pollution in sintering flue gas is mainly completed by installing a desulfurization device behind the sintering machine. Flue gas desulfurization methods include dry method, wet method and semi-dry method. Since the dry desulfurization efficiency is relatively low and the wet desulfurization has problems such as wastewater pollution, its application is restricted to a certain extent. There is a trend for sintering flue gas desulfurization to gradually develop towards semi-dry desulfurization. When the desulfurization atomizer is used for a long time or in case of problems, it needs to be maintained, and a rotary maintenance platform is required during maintenance.

[0003] According to the Chinese patent with the publication number CN210210306U, a special rotary maintenance platform for desulfurization atomizers in waste power plants is disclosed. This design can meet the maintenance of desulfurization atomizers of different sizes and is convenient to use. By rotatably connecting the chassis and the base through a connecting block, this design can realize the left and right rotation of the maintenance platform, thus facilitating all-round maintenance.

[0004] Regarding the above-mentioned disclosed patent content, since a maintenance box is provided for convenient storage of maintenance tools, and the tools need to be taken out during maintenance. However, when all the tools are placed in the maintenance box, due to the certain depth of the maintenance box, the maintenance box will block the line of sight of the staff, resulting in difficulty for the staff to accurately pick up the required maintenance tools, thereby reducing the picking efficiency of the tools. Content of the Utility Model

[0015] By adopting the above technical solution, when the bidirectional lead screw rotates, it can drive the movable seats to move, and the movable seats then drive the maintenance platform to move so as to adjust its position.

[0016] Further, the movable seat is threadedly connected to the bidirectional lead screw, and one end of the bidirectional lead screw penetrates to the outside of the second side frame and is connected with a hand wheel.

[0017] By adopting the above technical solution, when it is necessary to adjust the position of the maintenance table, the hand wheel can be rotated, so that the hand wheel can drive the bidirectional lead screw to rotate, and then drive the movable seat to move.

[0018] Further, a maintenance table is installed between the movable seat and the sliding seat, and a through hole is opened on the maintenance table.

[0019] By adopting the above technical solution, the setting of the maintenance table and the through hole facilitates the maintenance of the atomizer, and the movable seat will drive the maintenance table to move when it moves.

[0020] Further, a sliding groove is also opened on the top of the base, two sliders are arranged inside the sliding groove, and a support column is installed between the sliders and the rotating frame.

[0021] By adopting the above technical solution, when the rotating frame rotates, it will drive the support column to rotate, and the support column will drive the slider to slide inside the sliding groove, thereby improving the stability of the rotating frame when it rotates.

[0022] Further, universal wheels are installed on the four sides of the bottom of the base, and a handle is installed on the top of the cover plate.

[0023] By adopting the above technical solution, the setting of the universal wheels facilitates the movement of the platform and improves the convenience of platform transportation.

[0024] Further, the two placing plates are respectively slidably connected to the second maintenance box and the first maintenance box.

[0025] By adopting the above technical solution, the placing plate can slide inside the second maintenance box and the first maintenance box.

The setting of the universal wheels 2 facilitates the movement of the platform and improves the convenience of platform transportation.

[0041] Refer to Figures 1-5 , a second side frame 8 is installed on one side of the second maintenance box 6. A bidirectional lead screw 11 is connected to the inside of the second side frame 8 through a bearing. Two movable seats 12 are sleeved on the outer wall of the bidirectional lead screw 11. When the bidirectional lead screw 11 rotates, it can drive the movable seats 12 to move, and the movable seats 12 then drive the maintenance platform 14 to move in order to adjust its position. The movable seats 12 are threadedly connected to the bidirectional lead screw 11. One end of the bidirectional lead screw 11 penetrates to the outside of the second side frame 8 and is connected to a hand wheel 10. When it is necessary to adjust the position of the maintenance platform 14, the hand wheel 10 can be rotated, so that the hand wheel 10 can drive the bidirectional lead screw 11 to rotate, and then drive the movable seats 12 to move. A maintenance platform 14 is installed between the movable seats 12 and the sliding seats 13, and a through hole 15 is provided on the maintenance platform 14.

At this time, the support plate 906 can support the cover plate 904, and thus there is no need for the staff to always hold the cover plate 904.

[0047] Embodiment 3:

[0048] On the basis of the above Embodiment 1, in order to improve the stability of the rotating frame 4 during rotation, the following structure is provided.

[0049] Refer to Figure 1 、 Figure 2 and Figure 4 , a sliding groove 17 is further formed at the top of the base 1. Two sliders 18 are arranged inside the sliding groove 17, and a support column 16 is installed between the slider 18 and the rotating frame 4. When the rotating frame 4 rotates, it will drive the support column 16 to rotate, and the support column 16 will drive the slider 18 to slide inside the sliding groove 17, thereby improving the stability of the rotating frame 4 during rotation.

[0050] The working principle of the present utility model is as follows: First, when using this maintenance platform, the positions of the two maintenance platforms 14 can be adjusted according to the size of the desulfurization atomizer. The adjustment process is to rotate the bidirectional lead screw 11 by turning the handwheel 10, so that the bidirectional lead screw 11 rotates, thereby driving the two movable seats 12 to move simultaneously, then driving the maintenance platform 14 to move, and driving the sliding seat 13 to slide inside the first side frame 7, so as to adjust the position of the maintenance platform 14;

[0051] When performing maintenance, take out the tools required in the first maintenance box 5 or the second maintenance box 6.

The pull plate 903 then pulls the fixed plate 902, causing the fixed plate 902 to move upward. The fixed plate 902 then drives the placement plate 901 to move upward, and the placement plate 901 drives the tools to move upward. When the top of the placement plate 901 moves to be flush with the top of the first maintenance box 5 or the second maintenance box 6, stop pulling the cover plate 904. At this time, the tools can be removed from the first maintenance box 5 or the second maintenance box 6, facilitating the staff to take the required tools;

[0052] Then rotate the support plate 906 so that the support plate 906 rotates out of the storage groove 905. When the bottom of the support plate 906 contacts the stopper 909, the stopper 909 limits the support plate 906, and the support plate 906 can support and limit the cover plate 904, preventing the cover plate 904 from rotating back, and thus eliminating the need for the staff to always hold the cover plate 904;

[0053] When it is necessary to rotate the maintenance table 14, the motor 3 can be started. The operation of the motor 3 can drive the rotating frame 4 to rotate. The rotating frame 4 drives the first maintenance box 5 and the second maintenance box 6 to rotate, and drives the maintenance table 14 to rotate, facilitating the maintenance of the atomizer.
