Description

Technical Field

[0001] The utility model belongs to the technical field of hot-dip galvanized bridge frames, and particularly relates to a leveling device for hot-dip galvanized bridge frame section steels. Background Art

[0002] A hot-dip galvanized bridge frame is a steel bridge frame that has been subjected to hot-dip galvanizing treatment. Its outer layer is treated by hot-dip galvanizing to increase its corrosion resistance and service life. Such bridge frames are mainly used for power cables, control cables, lighting, wiring, etc., and are suitable for laying in indoor, outdoor, overhead, cable trench, tunnel and other environments.

[0003] Hot-dip galvanized bridge frames are usually made of C-shaped steels. During the production process of hot-dip galvanized bridge frames, the C-shaped steels need to be leveled so that the produced hot-dip galvanized bridge frames have excellent quality. When leveling the C-shaped steels, a leveling device is required. Although the existing leveling devices can play a leveling role, since the width of the support plate for placing the C-shaped steels is fixed, it results in that the same specification of support plate can only level the corresponding specification of C-shaped steels, and the flexibility of use is poor. Therefore, it needs to be improved. Summary of the Utility Model

The bottom end of the first air cylinder 11 is fixedly connected with an upper leveling plate 12.

[0025] The operator places the section steel on the top of the fixed support plate 3, so that the inner surface of the section steel contacts with the outer surfaces of the fixed support plate 3 and the moving support plates 5. Then, by starting the first air cylinder 11, the first air cylinder 11 drives the upper leveling plate 12 to move downward, so that the upper leveling plate 12 can level the section steel.

[0027] As a technical optimization scheme of the utility model, when the extension plate 13 moves downward along the inner surface of the moving support plate 5, the overall length of the moving support plate 5 and the extension plate 13 will be extended.

[0028] Among them, a connecting block 15 located inside the notch 14 is fixedly installed at the top of the inner side of the extension plate 13. The outer surface of the connecting block 15 is movably connected with the inner surface of the notch 14.

[0029] As a technical optimization scheme of the utility model, by setting the connecting block 15, when the connecting block 15 moves downward along the inner surface of the notch 14, it can drive the extension plate 13 to move downward.

[0030] Among them, a movable frame 16 is fixedly connected to the inner side of the connecting block 15. The outer surface of the movable frame 16 is movably connected with the inner surface of the moving support plate 5.

[0031] As a technical optimization scheme of the utility model, when the movable frame 16 moves downward, it can drive the connecting block 15 to move downward.

The other end of the round shaft 18 penetrates through the moving pallet 5 and extends into the interior of the moving pallet 5 and is movably sleeved with the inner wall of the moving pallet 5.

[0033] As a technical optimization scheme of the present utility model, after the power motor 17 is started, the round shaft 18 will rotate.

[0034] Among them, a disc 19 is fixedly sleeved on the outer surface of the round shaft 18. A round block 20 is fixedly sleeved inside the top end of the disc 19. The outer surface of the round block 20 is movably sleeved with the inner surface of the movable frame 16.

[0035] As a technical optimization scheme of the present utility model, when the disc 19 rotates, it will drive the round block 20 to rotate around the round shaft 18 as the axis.

[0036] Among them, a second air cylinder 21 is fixedly installed on the top end of the bottom plate 1. The number of the second air cylinders 21 is two.

[0038] The working principle and usage process of the present utility model:

[0039] The operator sleeves the C-shaped steel on the outer surfaces of the fixed pallet 3 and the moving pallet 5, and then starts the driving motor 6, so that the rotating shaft 7 drives the rotating rod 8 to rotate, and further enables the hinge rod 9 to push the two moving pallets 5 to move away from each other, so that the two moving pallets 5 contact the inner surface of the C-shaped steel. Then, by starting the first air cylinder 11, the first air cylinder 11 drives the upper leveling plate 12 to move downward, so that the upper leveling plate 12 can level the top of the C-shaped steel, and further can flatten C-shaped steels with different widths.

[0040] When the C-shaped steel is sleeved on the outer surfaces of the fixed support plate 3 and the movable support plate 5, the power motor 17 can be started to drive the circular shaft 18 to drive the disc 19 to rotate. Furthermore, the disc 19 can drive the circular block 20 to rotate around the circular shaft 18 as the axis, so that the circular block 20 can squeeze and push the inner surface of the movable frame 16, causing the movable frame 16 to move downward. Thus, the connecting block 15 can be driven to drive the extension plate 13 to move downward, and then the overall length of the extension plate 13 and the movable support plate 5 can be extended, so that the bottom of the extension plate 13 contacts the curled edge inside the steel section. Then, by starting the second air cylinder 21, the second air cylinder 21 can be driven to drive the side leveling plate 22 to move towards the C-shaped steel, so that the side surfaces of the C-shaped steel with different heights can be leveled.
