Description

Technical Field

[0001] This utility model relates to the field of frame structure technology, and in particular to a frame structure for waste incineration power plants. Background Technology

[0002] Waste heat boilers are core equipment for heat recovery in waste-to-energy plants. During operation, the convective heating surfaces and economizers of waste heat boilers are prone to ash accumulation and blockage due to the high viscous ash content in the flue gas. This problem leads to a sharp decline in heat exchange efficiency, increased system operating resistance, and even unplanned shutdowns, seriously affecting the plant's economic efficiency and safety. In traditional waste-to-energy plants, ash cleaning and maintenance of waste heat boilers are typically performed on fixed steel platforms built around the equipment itself.

[0003] However, fixed platforms cannot fully cover all potential blockage points. For parts on the sides, back, or at different heights of the equipment, operators have difficulty reaching the optimal working position, resulting in a significant reduction in the dust removal effect. In order to better address the above problems, promote the development of industry technology, and enhance core competitiveness, this application proposes a new composition structure that differs from existing technologies. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a frame structure for waste incineration power plants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A frame structure for a waste incineration power plant includes a fixed frame and a lifting platform. A motor is fixedly connected to one side of the fixed frame. One end of the motor output shaft is connected to a rotating shaft via a coupling. The rotating shaft is rotatably connected to the fixed frame via a bearing. Two sprockets are keyed to the outer side of the rotating shaft. A chain is provided on the outer side of each sprocket, and the chain meshes with the sprocket. A fixed block is fixedly connected to the top of the lifting platform, and one end of the chain is fixed to the fixed block.

[0006] As a further embodiment of this utility model, a protective shell is fixedly connected to the top of the fixing frame, and both the sprocket and the motor are located inside the protective shell. A heat dissipation vent is provided at the bottom of the protective shell.

[0007] As a further embodiment of this utility model, a sliding groove is provided on one side of the fixing frame, a counterweight is slidably connected in the sliding groove, and the other end of the chain is fixed to the counterweight.

[0008] As a further embodiment of this utility model, a guardrail is fixedly connected to the top of the lifting platform, and two hinges are fixedly connected to the outer side of the guardrail. The other end of each of the two hinges is fixedly connected to the same door panel.

[0009] As a further embodiment of this utility model, both the door panel and the guardrail are provided with insertion holes on one side, and the same pin is slidably connected in the two insertion holes.

[0010] As a further improvement of this invention, the top of the lifting platform is fixedly connected to two guide frames.

[0011] As a further embodiment of this utility model, two guide rods are fixedly connected to the top inner wall of the fixed frame, and the lifting platform slides along the guide rods.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model features a movable lifting platform structure. The platform is driven by a motor and a chain drive, enabling it to rise and fall along the outside of the waste heat boiler. In conjunction with the rotating shaft and sprocket assembly on the fixed frame, it allows operators to switch working positions at different heights, easily covering hard-to-reach areas such as the sides and back of the equipment. This effectively solves the problem of limited coverage of the fixed platform, improving the ash removal effect and maintenance convenience.

[0013] 2. This utility model is equipped with a counterweight. When the lifting platform rises or falls, the counterweight slides synchronously along the slide groove, which can offset part of the platform's own weight, reduce the motor load and improve the stability of operation. At the same time, it can provide a certain tension to the chain, preventing the chain from skipping teeth or falling off due to loosening during long-term use, and extending the service life of the transmission components.

[0014] 3. This utility model is equipped with a combination structure of guardrail and lockable door panel. After the operator enters the platform, the door panel is fixed by the pin, which, together with the guardrail, forms a closed-loop protection to prevent accidental falls during operation. At the same time, the door panel can be opened by hinge rotation, which facilitates personnel entry and exit, taking into account both safety and ease of operation. Attached Figure Description

[0016] 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. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-4 A frame structure for a waste incineration power plant includes a fixed frame 4 and a lifting platform 12. The fixed frame 4 is installed on the outside of the waste heat boiler 2. The outside of the waste heat boiler 2 is provided with multiple maintenance doors 3. The waste heat boiler 2 includes a base 1 below it. The lifting platform 12 is provided on the outside of the base 1. A motor 16 is fixed to one side of the fixed frame 4 by bolts. The motor 16 can be a special motor for large lifting equipment, such as the ZD series conical rotor motor ZD141-4 (electric hoist motor), with a power of 7.5kW, suitable for loads of 5 tons or less. One end of the output shaft of the motor 16 is connected to a rotating shaft 18 through a coupling, and the rotating shaft 18 is rotatably connected to the fixed frame 4 through a bearing. Two sprockets 17 are keyed to the outside of the rotating shaft 18. A chain 6 is provided on the outside of each of the two sprockets 17, and the chain 6 meshes with the sprocket 17. The top of the lifting platform 12 is fixed with a fixing block 15 by bolts, and one end of the chain 6 is rotatably fixed to the fixing block 15 by a locking pin; A slide groove 14 is provided on one side of the fixed frame 4. A counterweight 7 is slidably connected in the slide groove 14, and the other end of the chain 6 is fixed to the counterweight 7. The counterweight 7 slides synchronously in the opposite direction along the slide groove 14. The gravity balance of the counterweight 7 offsets part of the weight of the lifting platform 12, reducing the operating load of the motor 16. When in use, the motor 16 is started, and the output shaft of the motor 16 drives the rotating shaft 18 to rotate through the coupling. The sprocket 17 on the outside of the rotating shaft 18 rotates synchronously with it. The chain 6, which meshes with the sprocket 17, starts to move under the drive of the sprocket 17. The fixed block 15 connected to one end of the chain 6 drives the lifting platform 12 to slide along the outside of the waste heat boiler 2, so that the operator can switch working positions at different heights and easily cover hard-to-reach areas such as the sides and back of the equipment. This effectively solves the problem of limited coverage of the fixed platform and improves the ash cleaning effect and maintenance convenience.

[0018] In this utility model, the top of the fixing frame 4 is fixed with a protective shell 5 by bolts, and the sprocket 17 and the motor 16 are both located inside the protective shell 5. The bottom of the protective shell 5 is provided with a heat dissipation vent. The protective shell 5 plays a role in dust prevention and protection for the internal sprocket 17 and motor 16, while the heat dissipation vent ensures the heat dissipation needs of the motor 16 during operation. The top of the lifting platform 12 is fixedly connected to a guardrail 8. Two hinges 9 are fixedly connected to the outside of the guardrail 8. The other end of each of the two hinges 9 is fixedly connected to the same door panel 10. The door panel 10 can be opened by rotating the hinges 9, which facilitates personnel entry and exit and takes into account both safety and ease of operation.

[0019] In particular, both the door panel 10 and the guardrail 8 have insertion holes on one side, and the same pin 11 is slidably connected in the two insertion holes. The door panel 10 and the guardrail 8 can be fixed by the pin 11, which increases the stability of the device. The top of the lifting platform 12 is fixedly connected to two guide frames 13. The guide frames 13 can guide the tamping tool when the worker cleans the waste heat boiler 2, which solves the problems of inaccurate force direction and low efficiency when cleaning ash manually. Two guide rods 19 are fixed to the top inner wall of the fixed frame 4 by bolts, and one end of the two guide rods 19 is fixed to the base 1. The lifting platform 12 slides along the guide rods 19, which can ensure that the lifting platform 12 always maintains a stable vertical movement trajectory during the lifting process, and avoids platform deviation or jamming due to shaking.

[0020] Working principle: When the operator needs to perform equipment maintenance or dust removal, first open the door panel 10 by rotating the hinge 9, enter the lifting platform 12, and then insert the pin 11 into the hole between the door panel 10 and the guardrail 8 to fix the door panel 10 and form a closed-loop protection. When the motor 16 is started, the output shaft of the motor 16 drives the rotating shaft 18 to rotate through the coupling. The sprocket 17 on the outside of the rotating shaft 18 rotates synchronously with it. The chain 6, which meshes with the sprocket 17, starts to move under the drive of the sprocket 17. The fixed block 15 connected to one end of the chain 6 drives the lifting platform 12 to slide up and down along the guide rod 19. At the same time, the counterweight block 7 connected to the other end of the chain 6 slides synchronously in the opposite direction along the slide groove 14. The gravity balance of the counterweight block 7 offsets part of the weight of the lifting platform 12, reducing the operating load of the motor 16.

[0021] During the lifting process, the protective shell 5 provides dust protection for the internal sprocket 17 and motor 16, while the heat dissipation vents ensure the motor 16 meets its heat dissipation needs during operation. Once the lifting platform 12 reaches the designated working height, operators can work on the sides and back of the waste heat boiler 2 under the protection of the guardrail 8. After the work is completed, the motor 16 can be reversed to lower the lifting platform 12 to its initial position. The entire process is convenient, safe, and effectively improves the efficiency and reliability of equipment maintenance operations in waste incineration power plants.

[0022] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
