A mobile device for SCR catalyst modules

Abstract

This utility model discloses an SCR catalyst module moving device, including a base plate. Multiple sliding rods are fixedly connected to one end and the other end of the base plate. These sliding rods are slidably connected to the same platform. Multiple vertical rods are fixedly connected to the platform, and these vertical rods are fixedly connected to the same first plate. A screw is rotatably connected between the first plate and the platform. This utility model uses a motor-driven screw, combined with vertical rod guidance, to drive the second plate and hooks to achieve vertical lifting and lowering of the SCR catalyst module. This replaces manual handling, easily handles heavy modules, and avoids safety hazards such as falls. The vertical rod guidance ensures stable lifting without wobbling, reducing collisions between the module and reactor components. The holes in the second plate can be adjusted by studs to adjust the hook spacing, adapting to modules of different sizes and further reducing the risk of collision. This improves operational safety and stability, protects the catalyst, and ensures denitrification efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of flue gas denitrification equipment, and in particular to a mobile device for an SCR catalyst module. Background Technology

[0002] In flue gas denitrification treatment of industrial boilers, power plant boilers, and other equipment, SCR technology is one of the most widely used denitrification technologies. Its core component, the catalyst module, needs to be inspected, replaced, or repaired regularly. However, existing technologies have many drawbacks in the movement and replacement of catalyst modules: due to the large weight of the modules, manual handling is not only laborious and difficult, but also poses safety hazards such as falling and injury; during the lifting and moving of modules using traditional hoisting equipment, the modules are prone to collisions with the reactor inner wall and other components, resulting in damage to the catalyst carrier or shedding of active components, affecting denitrification efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mobile device for SCR catalyst modules.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A mobile device for an SCR catalyst module includes a base plate. Multiple sliding rods are fixedly connected to one and the other ends of the base plate. These sliding rods are slidably connected to the same platform. Multiple vertical rods are fixedly connected to the platform and are fixedly connected to the same first plate. A screw is rotatably connected between the first plate and the platform. The screw is threadedly connected to a second plate, which is slidably connected to the multiple vertical rods. The second plate has two rows of equally spaced holes. Some of these holes are movably perforated by studs. Nuts are threadedly connected to one and the other ends of multiple studs, and hooks are rotatably connected to each stud.

[0005] Preferably, the platform body is threaded with a bolt, and a rubber block is fixedly connected to one end of the bolt, with the rubber block in contact with the base plate.

[0006] Preferably, a counterweight is fixedly connected to one end of the base plate.

[0007] Preferably, a crossbar is fixedly connected to one end and the other end of the second plate, and the length of the two crossbars is the same as the length of the second plate.

[0008] Preferably, wheels are fixedly connected to all four corners of the base plate.

[0009] Preferably, a rubber pad is placed between each of the plurality of nuts and the second plate.

[0010] Preferably, a motor is fixedly connected to the first plate, and the output end of the motor is fixedly connected to the screw.

[0011] The beneficial effects of this utility model are as follows: 1. Through the coordination of the platform, vertical rods, first plate, screw, second plate, stud, hook, holes, and nuts, a motor-driven screw, in conjunction with the guiding action of multiple vertical rods, smoothly raises and lowers the second plate. This allows the hooks on the second plate to move the SCR catalyst module vertically. The motor drive replaces manual handling, easily handling the significant weight of the catalyst module and avoiding the laboriousness and safety hazards of manual handling, such as falls and injuries. The guiding action of multiple vertical rods ensures stable and wobbly lifting, reducing the risk of collisions between the module and the reactor wall or other components, protecting the catalyst carrier and active components from damage. Simultaneously, the multiple holes on the second plate can be fixed by inserting studs and using nuts, flexibly adjusting the hook spacing to accommodate catalyst modules of different sizes. This further reduces the probability of collisions due to size mismatches, improving operational safety and stability while ensuring that denitrification efficiency is not affected by maintenance. 2. By coordinating the sliding rods, platform, and bolts, and utilizing the sliding connection between the platform and multiple sliding rods, along with the friction generated by the contact between the bolts and the base plate at the platform, the position can be fixed. The position of the platform can be adjusted, thereby changing the placement position of the second plate and hook, ensuring that the second plate and hook are aligned with the catalyst module. This improves the positioning accuracy of picking, placing, and installing, reduces the risk of collisions caused by positional deviations, and further ensures the safe transport and installation efficiency of the catalyst module.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1, referring to Figures 1 to 5 A moving device for an SCR catalyst module includes a base plate 1. Multiple sliding rods 2 are fixedly connected to one and the other ends of the base plate 1 to guide the movement of a platform 3. The sliding rods 2 are slidably connected to the same platform 3, allowing the platform 3 to move smoothly along the axial direction of the sliding rods 2, achieving horizontal position adjustment. Multiple vertical rods 4 are fixedly connected to the platform 3. The vertical rods 4 are evenly distributed and of uniform height, serving both structural support and guiding the lifting and lowering of subsequent components. The multiple vertical rods 4 are fixedly connected to the same first plate 5. The first plate 5 is rectangular and parallel to the platform 3, forming a stable frame structure. A screw 6 is rotatably connected between the first plate 5 and the platform 3. The screw 6 is threadedly connected to a second plate 7. When the screw 6 rotates, it can drive... The second plate 7 moves axially and is slidably connected to multiple vertical rods 4. The vertical rods 4 pass through the corresponding through holes of the second plate 7, restricting its rotational freedom and ensuring that the second plate 7 can only move vertically up and down along the vertical rods 4. The second plate 7 has two rows of holes 10 at equal intervals. Some of the holes 10 are movably connected to studs 8, providing multiple adjustment positions for the installation of studs 8. The studs 8 can be inserted into the appropriate hole according to the size of the catalyst module. Nuts 11 are threaded to one end and the other end of multiple studs 8. By tightening the nuts 11, the studs 8 can be fixed on the second plate 7 to achieve position locking. Multiple studs 8 are rotatably connected to hooks 9. The rotation of hooks 9 can easily hook the existing SCR catalyst module's grid.

[0016] In this embodiment, a bolt 13 is threaded through the platform 3, and a rubber block 14 is fixedly connected to one end of the bolt 13. The rubber block 14 is in contact with the base plate 1. When the bolt 13 is tightened, the rubber block 14 is in close contact with the surface of the base plate 1, and the friction force restricts the sliding of the platform 3, thereby fixing its position. A counterweight 18 is fixedly connected to one end of the base plate 1. The counterweight 18 can balance the eccentric torque generated by the device gripping the catalyst module and prevent the device from tipping over. A crossbar 15 is fixedly connected to one end and the other end of the second plate 7, which can enhance the structural strength of the second plate 7 and prevent it from deforming due to excessive load. The length of the two crossbars 15 is the same as the length of the second plate 7, which can enhance the structural strength of the second plate 7 and prevent it from deforming due to excessive load. The base plate 1 has wheels 17 fixedly connected to each of its four corners. The wheels 17 can be universal wheels with brakes, which facilitates the overall movement of the device and can lock the position during operation, improving operational flexibility. Rubber pads 12 are placed between the multiple nuts 11 and the second plate 7. The rubber pads 12 can increase the friction between the nuts 11 and the second plate 7, prevent the nuts 11 from loosening, and buffer the pressure when tightening to avoid damage to the surface of the second plate 7. The first plate 5 is fixedly connected to a motor 16. The model of the motor 16 is selected according to the actual working requirements. The output end of the motor 16 is fixedly connected to the screw 6. The output end of the motor 16 is fixedly connected to the screw 6 through a coupling, which can drive the screw 6 to rotate synchronously and provide power for the lifting and lowering of the second plate 7.

[0017] The working principle of this embodiment is as follows: During operation, the position of the platform 3 is first adjusted by the sliding cooperation between the platform 3 and multiple sliding rods 2, so that the second plate 7 and hook 9 are initially aligned with the SCR catalyst module. The bolts 13 at the platform 3 are tightened, and the position of the platform 3 is fixed by the friction generated by the contact between the rubber block 14 of the bolt 13 and the base plate 1, ensuring the positioning basis for subsequent operations. According to the size of the catalyst module, the studs 8 are inserted through the multiple holes 10 on the second plate 7 and fixed with nuts 11. The spacing of the hooks 9 is flexibly adjusted to adapt to the module specifications. Then, the motor 16 is connected to an external power supply and control device to drive the screw 6. Under the guidance of multiple vertical rods 4, the second plate 7 rises and falls smoothly, driving the hooks 9 to hook or place the catalyst module, realizing the vertical lifting and lowering movement of the module.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
