Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, and in particular to an external rust removal device for the steel structure of power transmission towers. Background Technology

[0002] In the power industry, power transmission towers are crucial structures supporting power lines. Rust can accumulate on the surface of the steel structures used to build these towers, affecting not only their appearance but also potentially reducing their strength and safety.

[0003] Traditional rust removal methods mostly rely on manual grinding, which is not only inefficient but also poses safety hazards. Furthermore, these methods have limited applicability when removing rust from steel structures of different sizes. To overcome these shortcomings, a highly efficient and safe external rust removal device for power transmission tower steel structures is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing manual grinding methods, which are not only inefficient but also pose safety hazards. Furthermore, these methods have limited applicability when removing rust from steel structures of different sizes. Therefore, this invention proposes an external rust removal device for power transmission tower steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An external rust removal device for steel structures of power transmission towers includes a frame. Multiple driven rollers are rotatably connected between the inner walls of both sides of the frame. The multiple driven rollers are divided into two groups and symmetrically arranged on both sides of the frame. A single driving roller is rotatably connected between the inner walls of both sides of the frame. The driving roller is located in the middle of the two groups of driven rollers. A trapezoidal plate slides through one side of the frame. A first rust removal component for removing rust from the steel structure is provided at one end of the trapezoidal plate.

[0007] A rectangular hole is provided on one side of the frame, and a crossbar slides through the inside of the rectangular hole. A second rust removal component for removing rust from the steel structure is provided at one end of the crossbar.

[0008] One side of the frame is provided with a drive assembly for driving the active roller and the driven roller to rotate.

[0009] In one possible design, the first rust removal assembly includes a second connecting plate fixedly connected to one side of the trapezoidal plate, a second grinding plate fixedly connected to one side of the second connecting plate, and two symmetrically arranged tension springs fixedly connected between one side of the second connecting plate and one side inner wall of the frame.

[0010] In one possible design, the second rust removal assembly includes a fourth grinding plate fixedly connected to one end of a crossbar, a first connecting plate fixedly connected to the top of the fourth grinding plate, a spring fixedly connected to one side of the bottom of the crossbar, and the same L-shaped plate fixedly connected between the bottom of the crossbar and the bottom inner wall of the rectangular hole.

[0011] In one possible design, both the first connecting plate and the second connecting plate have multiple threaded holes inside, and a fixing screw passes through the internal threads of the threaded holes. A first grinding plate is provided on one side of the second connecting plate, and a third grinding plate is provided on one side of the bottom of the first connecting plate. Threaded grooves are provided on the top of the third grinding plate and one side of the first grinding plate, and the threaded grooves are threadedly connected to the fixing screws.

[0012] In one possible design, the drive assembly includes a rectangular cover fixedly connected to one side of a frame, through which a plurality of rotating rods rotatably pass. One end of each of the rotating rods is fixedly connected to one end of a drive roller and a plurality of driven rollers, respectively. A synchronous wheel is fixedly sleeved on the outer wall of each rotating rod, and the same conveyor belt is drivenly sleeved on the outer wall of two adjacent synchronous wheels. A servo motor is fixedly connected to one side of the rectangular cover, and the output shaft of the servo motor is fixedly connected to one end of one of the rotating rods.

[0013] In one possible design, a round rod is fixedly connected to one end of the drive roller, and an eccentric plate is fixedly sleeved on the outer wall of the round rod. The eccentric plate is used in conjunction with a trapezoidal plate and a spring.

[0014] In one possible design, the frame is fixedly connected to legs on both sides of its bottom, and a protective cover is fixedly connected to the top of the frame.

[0015] In one possible design, the bottom inner wall of the frame is provided with a sloping groove.

[0016] In this application, during use, the steel structure to be derusted is placed on top of the driven roller shaft, the servo motor is started, and the output shaft of the servo motor drives one of the rotating rods to rotate. Through the external synchronous belt and synchronous pulley, multiple rotating rods are driven to rotate synchronously. The rotating rods drive the driven roller shaft and the driving roller shaft to rotate. At this time, the steel structure can be conveyed forward and enter the interior of the protective cover for derusting.

[0017] Furthermore, when the active roller rotates, it drives the round rod to rotate, which in turn drives the eccentric plate to rotate. The eccentric plate pushes the trapezoidal plate to move laterally, which in turn drives the second connecting plate to move laterally. The second connecting plate then drives the first and second grinding plates to move laterally. At this time, the first and second grinding plates can grind the top and bottom of the steel structure. The tension spring helps the first and second grinding plates to reset.

[0018] At the same time, the eccentric plate can also push the spring to move down, the spring drives the crossbar to move down, the crossbar squeezes the L-shaped plate, the crossbar drives the fourth grinding plate to move vertically downward, and through the connection of the first connecting plate, it can drive the third grinding plate to move down. At this time, the third grinding plate and the fourth grinding plate can grind the side of the steel structure to achieve rust removal.

[0019] In actual use, the distance between the third and fourth grinding plates can be adjusted, as can the height of the first grinding plate. By unscrewing the fixing screws to release the braking state of the first and third grinding plates, and adjusting the positions of the first and third grinding plates, the fixing screws are screwed in again to fix the first and third grinding plates again, thus completing the adjustment operation.

[0020] Beneficial effects: High efficiency and automation: By driving the active and driven rollers with servo motors, automatic conveying of the steel structure is achieved, greatly improving rust removal efficiency. Simultaneously, the use of eccentric plates, trapezoidal plates, and crossbars enables all-around grinding of the top, bottom, and sides of the steel structure, further enhancing the rust removal effect.

[0021] Meanwhile, by adjusting the fixing screws, the position and spacing of the grinding plate can be easily adjusted to adapt to steel structures of different specifications and shapes.

[0022] Safe and reliable: During operation, the steel structure is securely confined between the driven rollers, preventing shaking and jumping caused by grinding, thus ensuring the safety and stability of the rust removal process. Furthermore, the protective cover design prevents sparks and debris generated during grinding from injuring operators.

[0023] High applicability: This equipment is not only suitable for rust removal of steel structures of power transmission towers, but can also be widely used for rust removal and maintenance of other steel structures such as bridges and buildings, and has broad application prospects.
