Description

Technical Field

[0001] The utility model relates to a water cutting device, in particular to a coal mine crawler type mechanical arm water cutting device, belonging to the technical field of water cutting devices. Background Art

[0002] Waterjet cutting, also known as water jet cutting, is a high-pressure water jet cutting technology. It is a machine that uses high-pressure water jet cutting. Because of its advantages such as being less affected by material texture, low cost and easy operation, waterjet cutting is gradually becoming the mainstream cutting method in cutting technology. With the development of the times, waterjet cutting has gradually been applied to various industries. For example, in coal mining operations, multiple components are generally cut, while traditional cutting methods will generate a large amount of sparks during cutting, which poses a great safety hazard. Therefore, waterjet cutting devices have naturally replaced traditional cutting devices.

[0003] However, most of the existing water cutting devices have various problems. For example, in a water cutting mechanical vehicle disclosed in publication number CN108326750A, although it is easy to carry, compact in structure, and can adapt to places with large cutting areas, in the cutting operation in coal mines, it is often necessary to adjust the cutting angle to a certain extent according to the actual situation. In this technical solution and most of the current water cutting devices, the cutting angle is mostly fixed. Although the angle of some devices can be adjusted manually, due to the weak light inside the coal mine, it is not convenient to observe during adjustment. At the same time, the angles that can be adjusted by the current devices are mostly relatively single and cannot be applied to the complex environment inside the coal mine. Utility Model Content

The docking seats 32 are fixed to the upper and lower sides of the tray 31, and the docking seats 32 on the upper and lower sides of the tray 31 are perpendicular to each other. The transmission plate 33 rotates to connect the docking seats 32 of two adjacent trays 31, and the tray 31 is provided with several;

[0023] The support mechanism 3 also includes a pull rope 34, a servo motor 35 and a winding reel 36.

During cutting, the servo motor 35 drives the winding disk 36 to rotate, and then the winding disk 36 winds up the pull rope 34, and then the pull rope 34 causes the transmission plate 33 to rotate in the docking seat 32, thereby changing the angle between the two adjacent trays 31, so that the angle of the water cutting nozzle 4 can be adjusted quickly and accurately, and can be adjusted at multiple angles at the same time. It is simple, efficient and practical, and can be applied to the complex environment in the coal mine.
