Description

Technical Field

[0001] This application relates to the field of sandblasting equipment technology, and in particular to a deep surface sandblasting equipment for intelligent bridge steel box girder. Background Technology

[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges. They are generally used on bridges with large spans. With the rapid development of long-span bridge construction, the surface anti-corrosion treatment of steel box girders, as the main load-bearing components, directly affects the service life of the bridge.

[0003] Currently, traditional sandblasting equipment is placed on a track surface and moved along the track to perform sandblasting operations on steel box girders. However, traditional sandblasting equipment cannot adapt to tracks of different widths when working in different locations, making it inconvenient to move the sandblasting equipment. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an intelligent deep surface sandblasting equipment for bridge steel boxes, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a deep surface sandblasting device for steel box girder bridges, comprising a fixed frame, a moving mechanism inside the fixed frame, a mechanical arm fixedly connected to the surface of the moving mechanism, a nozzle fixedly connected to one side of the mechanical arm, a protective mechanism on one side of the fixed frame, an installation frame fixedly connected to the bottom of the fixed frame, a track at the bottom of the installation frame, an adjustment mechanism inside the installation frame, the adjustment mechanism comprising a second motor, the second motor fixedly connected to the installation frame, a threaded rod third fixedly connected to the output end of the second motor, a threaded rod second fixedly connected to one side of the threaded rod third, the thread directions of the threaded rod second and the threaded rod third being opposite, both the threaded rod second and the threaded rod third being rotatably connected to the installation frame, both the threaded rod second and the threaded rod third being threadedly connected to the outside of a moving plate, the moving plate being slidably connected to the installation frame, and a driving mechanism on one side.

[0006] In a preferred embodiment, the moving mechanism includes a motor, which is fixedly connected to a fixed frame. A threaded rod is fixedly connected to the output end of the motor, and the threaded rod is rotatably connected to the fixed frame. A movable frame is threadedly connected to the external thread of the threaded rod, and the movable frame is slidably connected to the fixed frame. The movable frame is fixedly connected to a robotic arm.

[0007] By adopting the above technical solution, the output end of motor one drives the threaded rod one to rotate, and the rotation of the threaded rod one drives the moving frame to move. Then, the moving frame slides on the surface of the fixed frame to drive the position adjustment of the robotic arm, which can better adjust the position of the robotic arm.

[0008] In a preferred embodiment, the protection mechanism includes a damper, which is fixedly connected to a fixed frame. A baffle is fixedly connected to one side of the damper, and a spring is sleeved on the outside of the damper.

[0009] By adopting the above technical solution, the fixed frame is protected by a baffle. When the baffle hits an obstacle, the damper buffers the impact force on the baffle, and the spring resets the damper and the baffle, which can better protect the fixed frame.

[0010] In a preferred embodiment, the driving mechanism includes a third motor, which is fixedly connected to the movable plate, and a drive wheel is fixedly connected to the output end of the third motor.

[0011] By adopting the above technical solution, the drive wheel contacts the surface of the track, and then the output end of the motor rotates to drive the drive wheel to rotate. The rotation of the drive wheel then drives the mounting bracket to slide on the surface of the track, which can better enable the mounting bracket to slide on the surface of the track.

[0012] In a preferred embodiment, a slider is fixedly connected to the surface of the movable plate, and a groove is formed on the surface of the mounting bracket. The slider is located inside the groove and is slidably connected to the groove.

[0013] By adopting the above technical solution, a slider is fixedly connected to the surface of the movable plate, and the slider is limited by the groove on the surface of the mounting frame, so that the movable plate can move better on the surface of the mounting frame.

[0014] In a preferred embodiment, a wear-resistant layer is fixedly connected to the surface of the mounting bracket, and the wear-resistant layer is a ceramic component.

[0015] By adopting the above technical solution, a wear-resistant layer is fixedly connected to the surface of the mounting bracket, and the wear-resistant layer further enhances the wear resistance of the mounting bracket, thus improving its wear resistance.

[0016] In a preferred embodiment, a limiting groove is formed on the surface of the fixed frame, and the limiting groove is adapted to the movable frame.

[0017] In a preferred embodiment, a limiting groove is formed on the surface of the fixed frame, and the limiting groove limits the movement of the movable frame, which can better enable the movable frame to move on the surface of the fixed frame.

[0018] The beneficial effects of this application are: 1. This intelligent deep surface sandblasting equipment for bridge steel boxes comprises a threaded rod 2, a threaded rod 3, a moving plate, and a motor 2. The output end of motor 2 rotates, driving threaded rods 2 and 3 to rotate. Threaded rods 2 and 3 then drive two moving plates to move on the surface of the mounting frame. The distance between the two moving plates can be adjusted to adapt to tracks of different widths, avoiding the problem of traditional sandblasting equipment being unable to adapt to tracks of different widths when working in different locations, thus improving practicality.

[0019] 2. This intelligent deep surface sandblasting equipment for bridge steel boxes uses a damper, spring, and baffle. The baffle protects the fixed frame, and when the baffle hits an obstacle, the damper buffers the impact force on the baffle, and the spring resets the damper and baffle. This avoids the problem of traditional sandblasting equipment being unable to protect the fixed frame, thus improving its practicality. Attached Figure Description

The wear-resistant layer is fixedly connected to the surface of the mounting bracket 10, and the wear-resistant layer further enhances the wear resistance of the mounting bracket 10.

[0030] Working principle: The mounting bracket 10 is placed on the surface of the track 11. The output end of motor 2 34 rotates, driving threaded rods 2 31 and 3 32 to rotate. Threaded rods 2 31 and 3 32 then drive two movable plates 33 to move on the surface of the mounting bracket 10, adjusting the distance between the two movable plates 33 to accommodate tracks of different widths. The drive wheel 42 then contacts the surface of the track 11, and the output end of motor 3 41 rotates, driving the drive wheel 42 to rotate. The rotation of the drive wheel 42 then drives the mounting bracket 10 to move on the track. The surface of 11 slides, and then the mounting bracket 10 moves to drive the fixed bracket 1 to move. Then the output end of motor 21 rotates to drive the threaded rod 22 to rotate. Then the threaded rod 22 rotates to drive the moving bracket 23 to move. Then the moving bracket 23 slides on the surface of the fixed bracket 1 to drive the robotic arm 6 to adjust its position. Then the nozzle 7 on the surface of the robotic arm 6 performs sandblasting. When the baffle 53 hits the obstacle, the damper 51 buffers the impact force on the baffle 53. Then the spring 52 resets the damper 51 and the baffle 53.
