Abstract

The invention relates to a crawler belt walking wet type concrete sprayer comprising a frame, a crawler belt walking mechanism, a stirring and overturning mechanism, a spraying mechanism and a hydraulic system. The crawler belt walking mechanism is arranged at the both sides of the frame; a hydraulic pump of the hydraulic system drives a walking motor of the crawler belt walking mechanism through a hydraulic oil path; the walking motor drives a driving wheel to rotate through a speed reducer, so that the machine walks; the hydraulic system and the spraying mechanism are respectively arranged at the both ends of the frame; the stirring and overturning mechanism is arranged on the frame between the hydraulic system and a conveying mechanism; the stirring and overturning mechanism forcibly stirs a concrete material, and overturns a stirring tank, so that the concrete material inside the stirring tank is poured into a material tank of a concrete pump; and the material is conveyed through the concrete pump; and compressed air is added at the position of a spraying opening in a mixing manner, so that the concrete is sprayed. The wet type concrete sprayer provided by the invention integrates the functions of walking, stirring, conveying and spraying into a whole; the rebound ratio is less than 5%; the wet type concrete sprayer has the advantages of no dust, safe, reliable and high-efficiency use and humanization. The wet type concrete sprayer uses full-hydraulic control and has the advantages of stable conveying and simple operation, so that the underground anti-explosion problem can be effectively solved.

Description

technical field

[0001] The invention relates to the technical field of engineering construction machinery, in particular to a crawler wet concrete sprayer. Background technique

[0002] Concrete spraying machine is suitable for spraying concrete construction in support projects such as coal mines, metallurgy, hydropower, railways, subways, construction projects, etc. Shotcrete is to use compressed air to transport concrete mixture in a certain proportion through pipelines and spray it to the affected area at high speed. Condensation and hardening on the sprayed surface form a concrete support layer. In recent years, shotcrete technology has been widely used in construction, railway tunnel construction, mine shaft construction, slope reinforcement and other fields due to its simple process, economical cost and fast construction speed. The common method of wet spraying in engineering is that the concrete mixing station provides clinker concrete, and the concrete is transport...
