Description

Technical Field

[0001] The invention relates to the technical field of engineering bridge equipment, in particular to a burr removal device for engineering bridge steel. Background Art

[0002] In engineering construction, the use of auxiliary temporary bridges is indispensable. However, the construction cost of existing reinforced concrete engineering bridges is high and the construction time is long. Not only does it consume a large amount of materials, but it cannot be reused, wasting resources. Steel is a material with a certain shape, size and performance made of steel ingots, steel billets or steel through pressure processing. Most steel processing is through pressure processing, which causes the processed steel (billets, ingots, etc.) to undergo plastic deformation. According to the different steel processing temperatures, it can be divided into cold processing and hot processing.

[0003] Currently, burrs on the market are mostly removed by grinding. However, this type of design will destroy the protective layer of the outer wall of the steel after use. In addition, most steel used in engineering bridges needs to have anti-corrosion and anti-rust functions. After grinding, the steel will lose the above protective effects, reducing the service life of the engineering bridge steel. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a burr removal device for engineering bridge steel, including an integral external mechanism, which also includes an integral main body. An integral main groove is opened at the side wall of the integral main body, and an integral secondary groove is opened at the top outer wall of the integral main body. The integral external mechanism provides an installation position for subsequent mechanisms, which has a stabilizing effect during operation, offsets the trembling and vibration generated during the operation of the mechanism, ensures the normal operation of the equipment, and avoids problems such as bumps.

[0005] The bottom support mechanism includes a supporting main frame that is slidably connected to the inner wall of the overall main groove, and a supporting rotating plate is rotatably connected to the end of the supporting main frame away from the overall body. A processing coil is fixedly connected to the inner wall of the supporting main frame. After the steel contacts the processing coil, the steel is easy to heat up when power is turned on. A sufficiently large current can soften the steel between the processing coils to avoid the phenomenon of steel material cracking during the processing process due to the hard and easy-to-crack characteristics of steel.

[0006] The internal detection mechanism includes a detection back plate fixedly connected to the back of the outer wall of the overall main body, a detection middle plate rotatably connected to the top outer wall of the detection back plate, and a detection top plate fixedly connected to the end of the detection back plate away from the detection back plate.

[0007] Preferably, the overall external structure also includes an overall back groove opened on the top outer wall of the overall main body, the inner wall of the overall back groove is fixedly connected to the overall electric rail, and the central axis of the bottom outer wall of the overall main body is fixedly connected to the overall bottom plate. After the device is heated for a period of time, the pressing part of the steel structure will melt, and then it will be pressed through the internal detection mechanism. This type of pressing effect can effectively avoid the phenomenon of metal rebound angle misalignment during cold pressing.

[0008] Preferably, the integral external mechanism also includes an integral bracket fixedly connected to the outer wall of the top of the integral base plate, the end of the integral bracket away from the integral base plate is fixedly connected to the outer wall of the integral main body, and the outer wall of the integral main body is fixedly connected to an integral electric board.

[0010] Preferably, a supporting telescopic plate is fixedly connected to the outer wall of the main frame, a supporting outer block is fixedly connected to the side wall of the supporting main frame, and a supporting arc plate is slidably connected to the top outer wall of the supporting outer block.

[0011] Preferably, the bottom support mechanism also includes several supporting single-phase wheels rotatably connected to the inner wall of the supporting arc plate, and the outer wall of the supporting single-phase wheel is rotatably connected to a lever outer rod, and the top outer wall of the lever outer rod is rotatably connected to the outer wall of the supporting arc plate. After the device is heated for a period of time, the pressing part of the steel structure undergoes heat melting, and then is pressed through an internal detection mechanism. This type of pressing effect can effectively avoid the phenomenon of misalignment of the metal rebound angle caused by cold pressing.

[0012] Preferably, the internal detection mechanism also includes a detection top block fixedly connected to the top outer wall of the detection back plate, a detection side block fixedly connected to the top outer wall of the detection middle plate, a number of detection springs fixedly connected to the outer wall of the detection side block, and the end of the detection spring away from the detection side block is fixedly connected to the outer wall of the detection top block. The working temperature of the metal heating element can reach 1000-1500°C depending on the type of material, and the raw materials can be easily heated. The resistance heating has uniform heating, high thermal efficiency, and less pollution to the environment.

Steel is an electrical conductor and has a high resistivity. Since heat is generated inside the steel, it is internal heating with high thermal efficiency. The use of the above materials can soften the metal inside the steel, and then the burrs are smoothed downward by the hammering of the detection pressing hammer, without damaging the external protective layer, thereby extending the service life.
