Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for elevated steel structures. Background Art

[0002] Elevated steel structures generally refer to steel structures used in the construction of bridges, elevated roads, large buildings and other projects that require large-span spatial structures. Steel beams are steel materials with an I-shaped cross-section, which provide high strength while maintaining a relatively low weight, making them very suitable for structures that need to bear heavy loads. After the steel beams are produced, grinding devices are required to grind their surfaces. However, due to the special shape of the steel beams, grinding is rather troublesome. Traditional grinding devices can only grind the flat upper and lower surfaces, and it is inconvenient to grind the groove structures on both sides of the steel beams. Manual handheld grinders are often required for grinding, which requires additional manpower for grinding, making the processing time-consuming, laborious and costly. At the same time, when grinding the steel beams, the friction during grinding will cause the steel beams to shift, resulting in the grinding head being unable to accurately grind along the preset path, thus leading to insufficient grinding or over-grinding.

[0025] The following is a detailed description of the elevated steel structure grinding device. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0026] The present application will be described in detail below with reference to the accompanying drawings and specific implementation manners. Embodiment

[0028] When grinding the outside of the steel beam, place the steel beam on the installation table 1 so that the steel beam with an I-shaped structure has its lower surface resting on a number of rolling rollers 12 for easy movement. The outside of the steel beam is ground by a grinding assembly to improve the grinding efficiency. Secondly, the steel beam can be restricted by a limiting assembly to prevent the steel beam from moving during grinding. Embodiment

[0029] On the basis of Embodiment 1, the grinding assembly includes: two mounting rods 2 are fixedly connected to the top of the installation table 1 near the middle position. On one side of the two mounting rods 2, there is an upper grinding mechanism 21. On the inner walls of the opposite sides of the two mounting rods 2, a side grinding mechanism 22 and an inner grinding mechanism 23 are respectively fixedly installed. The upper grinding mechanism 21 is composed of an electric guide rail 24, a slide table 25, a mounting frame 26, a pneumatic cylinder 27 and a grinding roller 28. An electric guide rail 24 is fixedly installed between the inner walls of the opposite sides of the two mounting rods 2. The outside of the electric guide rail 24 is equipped with a slide table 25. One side of the slide table 25 is fixedly installed with a mounting frame 26. A pneumatic cylinder 27 is fixedly installed on the mounting frame 26. The bottom end of the pneumatic cylinder 27 is connected to a grinding roller 28. The side grinding mechanism 22 is composed of a mounting frame a29, a driven roller a210, a driving roller a211, a grinding belt a212 and a driving motor a213. A mounting frame a29 is fixedly installed on the inner wall of one of the opposite sides of one of the mounting rods 2. A driven roller a210 and a driving roller a211 are respectively arranged inside the mounting frame a29. A grinding belt a212 is arranged between the outside of the driven roller a210 and the driving roller a211. A driving motor a213 is fixedly installed on the top of the mounting frame a29. The driving shaft at the bottom end of the driving motor a213 is connected to the axis of the driving roller a211. The inner grinding mechanism 23 is composed of a connecting frame 214, a mounting frame b215, a driven roller b216, a driving roller b217, a grinding belt b218 and a driving motor b219. A connecting frame 214 is fixedly installed on the inner wall of the other mounting rod 2. The connecting frame 214 is fixedly connected to a mounting frame b215 on one side. A driven roller b216 and a driving roller b217 are rotatably connected between the inner bottom and the inner bottom of the mounting frame b215. A grinding belt b218 is arranged between the outside of the driven roller b216 and the driving roller b217. A driving motor b219 is fixedly installed on the mounting frame b215. The driving shaft at the bottom end of the driving motor b219 is connected to the axis of the top end of the driving roller b217.

[0030] When grinding the steel beam, by controlling the distance of the pneumatic cylinder 27 to eject and retract, the surface of the upper grinding mechanism 21 just fits the upper surface of the steel beam. The electric guide rail 24 can control the left and right movement of the sliding table 25. When the sliding table 25 moves, it will drive the mounting frame 26, the pneumatic cylinder 27 and the grinding roller 28 to move together, so as to adjust the position of the grinding roller 28. Then, one end of the steel beam is moved between the two mounting rods 2, and its top is fitted with the grinding roller 28. The groove side grinding mechanisms 22 and the inner grinding mechanisms 23 on both sides are respectively located in the grooves on both sides of the steel beam. Then, the grinding roller 28, the driving motor a213 and the driving motor b219 are started at the same time. After the grinding roller 28 is started, it rotates, and the grinding roller 28 rotates to grind the upper surface of the steel beam. After the driving motor a213 is started, it drives the driving roller a211 to rotate. The driving roller a211 rotates and cooperates with the driven roller a210 to start the grinding belt a212 to move. Since the structure of the driven roller a210 fits the groove on one side of the steel beam and extends to fit the inner wall of the groove, the movement of the grinding belt a212 can grind the side surface of the steel beam. After the driving motor b219 is started, it drives the driving roller b217 to rotate. The driving roller b217 cooperates with the driven roller b216 to drive the grinding belt b218 to rotate. The upper surface and the lower surface of the grinding belt b218 are respectively fitted with the inner top and the lower bottom of the groove on one side of the steel beam. Therefore, when rotating, it can grind the inner top and the lower bottom of the groove on one side of the steel beam. After the upper surface of the steel beam is ground, the steel beam is flipped so that the lower surface faces up, and the positions of the grooves on both sides are interchanged. According to the above principle, the remaining unprocessed lower surface of the steel beam, the inner top and the inner bottom of the groove on one side of the steel beam, and the side surface of the groove on the other side are ground, so as to complete the grinding of the external surface of the steel beam. Embodiment

[0031] On the basis of Embodiment 1, the limiting component includes: two limiting plates 3 are symmetrically arranged between the inner walls on the opposite sides of the two gantry frames a14 respectively. Grooves 31 are respectively opened on the opposite sides of the two limiting plates 3. Limiting rollers 32 are rotatably connected between the inner top and the inner bottom of the groove 31. Threaded rods a33 are respectively threadedly connected to the opposite sides of the gantry frame a14. The opposite ends of the two threaded rods a33 are respectively rotatably connected to one side of the two limiting plates 3. Two through holes are respectively opened on the opposite sides of the gantry frame a14. Guide rods 34 are respectively slidably connected to the inside of the two through holes. One ends of the two guide rods 34 on the same plane are respectively rotatably connected to one side of the limiting plate 3. A pressure roller 35 is arranged between the opposite sides of the two gantry frames b15. Threaded rods b36 are respectively fixedly connected to the tops of the two gantry frames b15. The bottom ends of the threaded rods b36 are respectively rotatably connected to the top of the pressure roller 35. Guide grooves 37 are respectively opened on the inner walls on the opposite sides of the two gantry frames b15. Guide blocks 38 are respectively fixedly connected to the opposite ends of the pressure roller 35. The two guide blocks 38 are respectively located inside the two guide grooves 37.

[0032] It is necessary to limit the trajectory of the steel beam between the processed steel beams. By rotating the handwheel at one end of the threaded rod a33, the threaded rod a33 is screwed with the gantry a14. Since the limiting plate 3 is restricted by two guide rods 34, the limiting plate 3 can only move in the horizontal direction, and the threaded rod a33 is rotatably connected to the limiting plate 3. Therefore, the threaded rod a33 can rotate. When threaded, the threaded rod a33 can drive the limiting plate 3 to move. By controlling the rotation direction of the threaded rod a33, the moving direction of the limiting plate 3 can be controlled, and the relative movement of the two limiting plates 3 can be controlled. The two limiting rollers 32 clamp the steel beam, and the two limiting rollers 32 can rotate, so it will not affect the pushing of the steel beam. At the same time, rotate the handwheel at the top of the threaded screw b36 to drive the threaded screw b36 to be screwed with the gantry b15. The bottom end of the threaded screw b36 is rotatably connected to the pressure roller 35. Therefore, when threaded, it will drive the pressure roller 35 to move. And the guide blocks 38 on both sides of the pressure roller 35 are located inside the two guide grooves 37. Therefore, the pressure roller 35 can only move in the vertical direction. By controlling the rotation direction of the threaded screw b36, the rising or falling of the pressure roller 35 can be controlled, and the pressure roller 35 is controlled to descend to press the steel beam, so as to limit the moving trajectory of the steel beam and prevent the steel beam from moving during processing.

[0034] The above has introduced in detail a high-altitude steel structure grinding device provided by the embodiments of the present application.

The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
