[0001] This utility model relates to the field of pipeline rust removal, specifically a rust removal device for the surface of municipal heating pipelines with protective functions. Background Technology

[0002] As the core infrastructure of urban centralized heating systems, municipal heating pipelines are responsible for transporting high-temperature hot water. Their operating status directly affects the quality of winter heating for residents and the stability of urban energy supply. However, during long-term service, the pipelines face corrosion threats from multiple factors, thus requiring a rust removal device for the surface of municipal heating pipelines with protective functions.

[0003] Existing rust removal devices for municipal heating pipelines are not convenient for applying anti-rust oil to the pipes after rust removal, and the rust removal thickness is easily uneven due to fluctuations in the pushing speed. Therefore, there is an urgent need for a rust removal device for municipal heating pipelines with protective functions. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rust removal device for municipal heating pipelines with protective function, so as to solve the problem that existing rust removal devices for municipal heating pipelines with protective function are not convenient to apply anti-rust oil to the pipeline after rust removal, and the rust removal thickness is easily uneven due to fluctuations in pushing speed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust removal device for the surface of municipal heating pipelines with protective function, comprising a support frame, a collection frame welded to one end of the support frame, a collection hopper installed at the lower end of the collection frame, positioning rods fixedly connected to the inner wall of the support frame, a fixing frame fixedly connected to the outer wall of the positioning rods, an electric push rod installed on the inner wall of the fixing frame, a lifting frame fixedly connected to one end of the electric push rod, a connecting rod installed on the inner wall of the lifting frame, a grinding belt attached to the outer wall of the connecting rod, a rotating rod attached to the inner wall of the grinding belt, a first motor installed at one end of the rotating rod, fixing rods fixedly connected to the inner wall of the first motor, a spring welded to the outer wall of the lifting frame, a rust-preventive oil funnel welded to one end of the spring, and a sponge installed at one end of the rust-preventive oil funnel.

[0006] Limiting rods are fixedly connected to the inner walls of the collection racks, and a second motor is fixedly connected to the outer wall of the limiting rods. A main rotating cylinder is installed at one end of the second motor, and a first rubber sleeve is attached to the outer wall of the main rotating cylinder. A secondary rotating cylinder is installed on the inner wall of the collection rack, and a second rubber sleeve is attached to the outer wall of the secondary rotating cylinder.

[0007] Preferably, the fixing frame is engaged with the electric push rod, and the fixing frame is symmetrically arranged about the central axis of the collection rack.

[0008] Preferably, the outer wall of the linkage rod is in close contact with the inner wall of the grinding belt, and the length of the inner wall of the linkage rod is greater than the width of the outer wall of the grinding belt.

[0009] Preferably, the rust-preventive oil funnel is movably connected to the lifting frame, and the inner wall of the lifting frame has an open design.

[0010] Preferably, the outer wall of the main rotating cylinder is in close contact with the inner wall of the first rubber sleeve, and the outer wall of the first rubber sleeve is threaded.

[0011] Preferably, the rotating cylinder is movably connected to the collection rack, and the collection rack is configured with an inverted trapezoidal structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a rust-preventive oil funnel made of high-strength engineering plastic. The funnel has a tapered structure, wider at the top and narrower at the bottom, with an annular oil outlet at the bottom. Multiple guide grooves are evenly distributed on the inner wall of the outlet to ensure the rust-preventive oil flows uniformly to the outer wall of the pipe, preventing localized oil accumulation or uneven oil distribution. The funnel is movably connected to a lifting frame, allowing it to slide up and down to accommodate pipe operations at different heights. The funnel and the outer edge of the sponge form a tight fit, ensuring stable adhesion between the sponge and the pipe wall. The sponge is made of high-density oil-resistant sponge and is machined into an annular structure. The inner wall of the sponge fits tightly against the outer wall of the pipe. When the rust-preventive oil flows out from the bottom of the funnel, it first penetrates into the sponge and is evenly distributed through the sponge's pores, coating the outer wall of the pipe to form a continuous and dense rust-preventive oil film. This film, with its uniform thickness, effectively resists the corrosion of moisture and dust in the air. This invention uses a second motor to engage and fix the main rotating cylinder. The second motor serves as the power source and fixing core of the main rotating cylinder, transmitting stable power and driving the cylinder to rotate at a uniform speed. The main rotating cylinder, as the direct support and conveying component of the pipeline, has a threaded outer wall. Through the spiral guidance and friction enhancement characteristics of the threaded structure, it achieves uniform axial conveying of the pipeline, offsetting the speed fluctuations that may occur from the external pushing device, ensuring a constant relative movement speed between the rust removal parts and the pipeline surface, and thus ensuring a uniform rust removal thickness.

An electric push rod 6 is installed on the inner wall of the fixing frame 5, and the fixing frame 5 and the electric push rod 6 are engaged and connected. The fixing frame 5 is symmetrically arranged about the central axis of the collection frame 2. A lifting frame 7 is fixedly connected to one end of the electric push rod 6, and a linkage rod is installed on the inner wall of the lifting frame 7. 8. A grinding belt 9 is attached to the outer wall of the linkage rod 8. The outer wall of the linkage rod 8 is in close contact with the inner wall of the grinding belt 9, and the length of the inner wall of the linkage rod 8 is greater than the width of the outer wall of the grinding belt 9. A rotating rod 10 is attached to the inner wall of the grinding belt 9. A first motor 11 is installed at one end of the rotating rod 10. A fixing rod 12 is fixedly connected to the inner wall of the first motor 11. A spring 13 is welded to the outer wall of the lifting frame 7. A rust-proof oil funnel 14 is welded to one end of the spring 13. The rust-proof oil funnel 14 is movably connected to the lifting frame 7, and the inner wall of the lifting frame 7 has an open design. One end of the rust-preventive oil funnel 14 is fitted with a sponge 15. The funnel 14 is made of high-strength engineering plastic and has a tapered structure, wider at the top and narrower at the bottom. The bottom has an annular oil outlet, and multiple evenly spaced guide grooves on the inner wall of the outlet ensure that the rust-preventive oil flows evenly along these grooves to the outer wall of the pipe, preventing localized oil accumulation or uneven oil distribution. The rust-preventive oil funnel 14 is movably connected to the lifting frame 7, allowing it to slide up and down along the frame to accommodate pipeline operations at different heights. The outer edges of the rust-preventive oil funnel 14 and the sponge 15... The edges form a tight fit to ensure the stability of the adhesion between the sponge 15 and the outer wall of the pipe. The sponge 15 is made of high-density oil-resistant sponge and is processed into a ring structure. The inner side wall of the sponge 15 is tightly attached to the outer wall of the pipe. When the rust-preventive oil flows out from the bottom of the rust-preventive oil funnel 14, it will first penetrate into the interior of the sponge 15 and be evenly distributed through the pores of the sponge 15, so that the rust-preventive oil is evenly applied to the outer wall of the pipe to form a continuous and dense rust-preventive oil film. The rust-preventive oil can form a uniformly thick oil film on the outer wall of the pipe, which can effectively resist the corrosion of moisture and dust in the air.

The secondary rotating cylinder 20 is movably connected to the collection rack 2. Furthermore, the collection rack 2 is designed with an inverted trapezoidal structure. The second motor 17 is used to engage and fix the main rotating drum 18. The second motor 17 serves as the power source and fixing core of the main rotating drum 18, transmitting stable power and driving the drum to rotate at a uniform speed. The main rotating drum 18 serves as the direct support and conveying component of the pipeline. Its outer wall is designed with a threaded shape. Through the spiral guidance and friction enhancement characteristics of the threaded structure, the pipeline is conveyed axially at a uniform speed, which offsets the speed fluctuations that may occur from the external pushing device. This ensures that the relative movement speed between the rust removal parts and the pipeline surface is constant, thereby ensuring that the rust removal thickness is uniform.
