Description

Technical Field

[0001] This utility model relates to the field of maintenance tools, and in particular to a maintenance tool for electrostatic precipitators. Background Technology

[0002] Electrostatic precipitators achieve dust particle charging by ionizing the gas near the corona electrode through corona discharge, generating a large number of positive and negative ions, which then attach to the dust particles.

[0003] However, during the use of electrostatic precipitators, the cathode often hits the pressure-bearing insulator, causing damage to the pressure-bearing insulator. This will prevent the high-frequency power supply from operating normally and requires replacement. Replacement requires the use of a manual hoist for lifting, but the lifting process of a manual hoist is very unstable and can easily damage internal components such as the cathode wire. Utility Model Content

[0004] The purpose of this utility model is to provide a maintenance tool for electrostatic precipitators, which aims to solve the problem that the lifting process of existing manual hoist equipment for lifting pressure-bearing insulators is very unstable and easily causes damage to internal components such as cathode wires.

[0005] To achieve the above objectives, this utility model provides an electrostatic precipitator maintenance tool, including a portal frame, a cathode wire hook, and a lifting assembly. The lifting assembly is disposed on one side of the portal frame, and the cathode wire hook is hung on one side of the lifting assembly. The lifting assembly includes a telescopic cylinder, a fixed hook, a guide member, and a buffer rod. The guide member is fixedly connected to the portal frame and located on one side of the portal frame. The telescopic cylinder is fixedly connected to the portal frame and detachably connected to the guide member, and is located on one side of the portal frame. The fixed hook is fixedly connected to the guide member and located on the side of the guide member away from the telescopic cylinder. The buffer rod is disposed between the guide member and the portal frame.

[0006] The guide component includes a guide rail and a sliding plate. The guide rail is fixedly connected to the portal frame and is located on the side of the portal frame closer to the telescopic cylinder. The sliding plate is fixedly connected to the telescopic cylinder and slidably connected to the guide rail, and is located between the guide rail and the telescopic cylinder.

[0007] The slide plate includes a connecting ring, a base plate, and a slider. The connecting ring is detachably connected to the telescopic cylinder and is located on the side of the telescopic cylinder away from the portal frame. The base plate is fixedly connected to the connecting ring and is located on the side of the connecting ring away from the telescopic cylinder. The slider is fixedly connected to the base plate and slidably connected to the guide rail and is located on both sides of the base plate.

[0008] The buffer rod includes a damping rod and a buffer spring. The damping rod is fixedly connected to the base plate and the portal frame, and is located between the portal frame and the base plate. The buffer spring is sleeved on the outside of the damping rod.

[0009] The portal frame includes a frame body and a connecting plate. The frame body is fixedly connected to the telescopic cylinder and is located on one side of the telescopic cylinder. The connecting plate is fixedly connected to the frame body and is located at the bottom of the frame body.

[0010] This utility model discloses a maintenance tool for an electrostatic precipitator. The portal frame provides installation conditions for the lifting assembly and supports the entire maintenance tool. The cathode wire hook is hung at the bottom of the lifting assembly and is used to hook the cathode wire through the observation hole of the electrostatic precipitator insulation box for replacing the pressure-bearing insulator. This reduces the workload of maintenance personnel and improves the quality and speed of maintenance. The lifting assembly is used to smoothly lift the cathode wire hook and the hooked cathode wire. Specifically, the cathode wire hook hooks the fixed hook and extends the cathode wire hook into the observation hole of the electrostatic precipitator insulation box. At this time, the worker starts the telescopic cylinder through the controller. The output end of the telescopic cylinder extends and lowers the cathode wire hook to hook the cathode wire. Finally, the telescopic cylinder is started again through the controller, causing the output end of the telescopic cylinder to retract and lift the cathode wire. During this process, the buffer rod buffers the force of the telescopic cylinder, and the guide member guides the load-bearing insulator to rise smoothly. This solves the problem that the existing manual hoist equipment is very unstable when lifting the load-bearing insulator, which can easily cause damage to internal components such as the cathode wire.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figures 1 to 3 This utility model provides a maintenance tool for an electrostatic precipitator, including a portal frame 1, a cathode wire hook 2, and a lifting assembly 3. The lifting assembly 3 is disposed on one side of the portal frame 1, and the cathode wire hook 2 is hung on one side of the lifting assembly 3. The lifting assembly 3 includes a telescopic cylinder 4, a fixed hook 5, a guide 6, and a buffer rod 7. The guide 6 is fixedly connected to the portal frame 1 and located on one side of the portal frame 1. The telescopic cylinder 4 is fixedly connected to the portal frame 1 and detachably connected to the guide 6, and is located on one side of the portal frame 1. The fixed hook 5 is fixedly connected to the guide 6 and located on the side of the guide 6 away from the telescopic cylinder 4. The buffer rod 7 is disposed between the guide 6 and the portal frame 1.

[0018] In this embodiment, the portal frame 1 provides installation conditions for the lifting assembly 3 and supports the entire maintenance tool. The cathode wire hook 2 is hung at the bottom of the lifting assembly 3 and is used to hook the cathode wire through the observation hole of the electrostatic precipitator insulation box for replacing the pressure-bearing insulator, reducing the workload of maintenance personnel and improving maintenance quality and speed. The lifting assembly 3 is used to smoothly lift the cathode wire hook 2 and the hooked cathode wire. Specifically, the cathode wire hook 2 hooks onto the fixed hook 5 and extends the cathode wire hook 2 into the observation hole of the electrostatic precipitator insulation box. At this time, the worker starts the telescopic cylinder 4 through the controller. The output end of the telescopic cylinder 4 extends and lowers the cathode wire hook 2 to hook the cathode wire. Finally, the telescopic cylinder 4 is started again through the controller, causing the output end of the telescopic cylinder 4 to retract and lift the cathode wire. During this process, the force of the telescopic cylinder 4 is buffered by the buffer rod 7 and guided by the guide member 6, so that the pressure-bearing insulator can rise smoothly. This solves the problem that the existing manual hoist equipment is very unstable when lifting the pressure-bearing insulator, which can easily cause damage to internal components such as the cathode wire.

[0019] Furthermore, the guide member 6 includes a guide rail 8 and a slide plate 9. The guide rail 8 is fixedly connected to the portal frame 1 and is located on the side of the portal frame 1 close to the telescopic cylinder 4. The slide plate 9 is fixedly connected to the telescopic cylinder 4 and slidably connected to the guide rail 8, and is located between the guide rail 8 and the telescopic cylinder 4.

[0020] In this embodiment, the output end of the telescopic cylinder 4 drives the slide plate 9 to slide within the guide rail 8, thereby preventing the telescopic cylinder 4 from deviating to the side, which would cause the cathode wire hook 2 to deviate to the side and result in unstable lifting.

[0021] Furthermore, the slide plate 9 includes a connecting ring 10, a base plate 11, and a slider 12. The connecting ring 10 is detachably connected to the telescopic cylinder 4 and is located on the side of the telescopic cylinder 4 away from the portal frame 1. The base plate 11 is fixedly connected to the connecting ring 10 and is located on the side of the connecting ring 10 away from the telescopic cylinder 4. The slider 12 is fixedly connected to the base plate 11 and slidably connected to the guide rail 8, and is located on both sides of the base plate 11.

[0022] In this embodiment, the connecting ring 10 is provided for connecting the base plate 11 and the output end of the telescopic cylinder 4. The base plate 11 provides installation conditions for the slider 12. The output end of the telescopic cylinder 4 drives the base plate 11, so that the base plate 11 drives the slider 12 to slide within the guide rail 8, thereby guiding the output end of the telescopic cylinder 4.

[0023] Furthermore, the buffer rod 7 includes a damping rod 13 and a buffer spring 14. The damping rod 13 is fixedly connected to the base plate 11 and the portal frame 1, and is located between the portal frame 1 and the base plate 11. The buffer spring 14 is sleeved on the outside of the damping rod 13.

[0024] In this embodiment, when the output end of the telescopic cylinder 4 retracts, the base plate 11 is lifted, thereby squeezing the damping rod 13. The damping rod 13 achieves buffering of the force exerted by the telescopic cylinder 4 by squeezing the buffer medium therein. The setting of the buffer spring 14 further enhances the buffering effect of the damping rod 13 on the force exerted by the telescopic cylinder 4.

[0025] Furthermore, the portal frame 1 includes a frame body 15 and a connecting plate 16. The frame body 15 is fixedly connected to the telescopic cylinder 4 and is located on one side of the telescopic cylinder 4. The connecting plate 16 is fixedly connected to the frame body 15 and is located at the bottom of the frame body 15.

[0026] In this embodiment, the frame body 15 provides installation conditions for the lifting assembly 3 and supports the entire maintenance tool, and the connecting plate 16 is used to fix the frame body 15 to the ground.

[0027] The above-disclosed embodiments are merely preferred embodiments of an electrostatic precipitator maintenance tool of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
