Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically a robot for grinding and applying release agent to a secondary lining steel formwork trolley. Background Technology

[0002] In tunnel construction, the secondary lining trolley is a specialized piece of equipment essential for the secondary lining process. Primarily used for pouring and shaping concrete for the tunnel's inner walls, it is an indispensable piece of equipment in tunnel construction. A typical secondary lining trolley consists of a frame, formwork, hydraulic system, and walking system. The frame is the main structure of the trolley, providing support for the entire device. The formwork is the part that directly contacts the concrete. To ensure a smooth and flat surface, guaranteeing good concrete surface quality, and facilitating demolding, a release agent needs to be applied to the formwork surface each time it is used.

[0003] Traditional manual application of release agent has problems such as inconvenience, low efficiency, waste of release agent, and uneven application. On the other hand, using a high-pressure water gun to spray release agent can easily contaminate the steel bars, affecting structural safety. Furthermore, the existing secondary lining trolley formwork cannot be regularly polished, which will cause concrete to adhere to the surface of the steel formwork, resulting in poor appearance quality of the concrete surface. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A robot for grinding and applying release agent to a secondary lining steel mold trolley includes a trolley platform, magnetic wheels, and a release agent storage tank. Four magnetic wheels are located at the bottom of the trolley platform, with a rotating shaft fixedly installed in the middle of each wheel. One end of the rotating shaft is rotatably connected to a fixed plate mounted at the bottom of the trolley platform. Two turbines are mounted on the two rotating shafts at the rear of the trolley platform, and a worm gear meshes with each turbine. One end of the worm gear is directly connected to the output shaft of a first motor fixedly mounted at the bottom of the trolley platform. A wire brush roller and a coating roller are respectively located at the front and rear of the bottom of the trolley platform. One end of each wire brush roller and coating roller is engaged with a bearing fixedly mounted on a fixed plate on one side. The other end of the steel wire brush roller and the coating roller is engaged with a U-shaped frame rotatably mounted on a fixed plate on the other side. The U-shaped frame is fitted with screws and is fixedly connected to the steel wire brush roller and the coating roller by the screws. A driven gear is mounted on the rear shaft of the U-shaped frame connected to the steel wire brush roller. A driving gear is provided on one side of the driven gear and meshes with it. The driving gear is mounted on the output shaft of a second motor fixedly mounted at the bottom of the vehicle board. A fixed frame is mounted on the vehicle board, and a mold release agent storage box is mounted on the fixed frame. A water pipe is connected to the mold release agent storage box and passes through the vehicle board, positioned directly above the coating roller.

[0007] As a further embodiment of this utility model: a drip hole is provided at the bottom of the water pipe directly opposite the coating roller, and a manual valve is installed on the water pipe.

[0008] As a further improvement of this utility model: the end of the steel wire brush roller and the coating roller that is inserted into the bearing is provided with a limiting boss, and the limiting boss is adapted to the corresponding limiting groove opened on the inner ring of the bearing.
