Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a frame chassis of a wet spraying machine. Background Art
[0002] At present, dry spraying and wet spraying equipment are used in metal mines and coal mines. The main problems are large dust, low manual operation efficiency, low strength of dry sprayed concrete, and large repair volume. Compared with dry sprayed concrete, wet sprayed concrete has many advantages such as higher concrete structure strength, better spraying quality, low rebound rate, and low labor intensity. In the underground tunnels and deep well tunnels of anchor spraying support in mines and coal mines, due to the special transportation conditions underground, the commercial concrete on the ground cannot be transported to the wet spraying operation surface in time, and the space for setting up a mixing station underground is limited. The sand, stone, and cement materials for wet spraying on site can only be transported to the operation surface by rail mine car shafts or inclined shafts, or by wheeled mining trucks through ramps and scrapers. At present, there is no complete set of wet spraying and concrete production equipment suitable for small and medium-sized tunnel mines and coal mines. Therefore, it is necessary to develop a wet spraying equipment for solving the problem of wet spraying concrete in 2.5-5-meter mine tunnels, realize the on-site mixing of wet spraying concrete equipment underground, concrete batching and measurement, concrete transportation, and feeding of wet spraying operations to the crawler wet spraying machine system, so as to improve construction efficiency. In order to adapt to the wet spraying operation in a small space, the frame chassis of the wet spraying equipment will be one of the keys to whether the size of the wet spraying equipment can be reduced while ensuring its full functionality.
