Abstract
Description
Technical Field
[0001] This utility model relates to the field of shotcrete manipulators, and in particular to a shotcrete manipulator that is easy to move. Background Technology
[0002] Shotcrete support is now widely used in railway and highway tunnels, mine roadways, water conservancy and hydropower tunnels and culverts, subways, and various underground (military and civilian) buildings. Shotcrete devices used in engineering construction include wet shotcrete systems. Wet shotcrete systems, also known as wet shotcrete robots, wet shotcrete machines, shotcrete manipulators, or shotcrete robots, utilize compressed air to mix concrete with water in a specific ratio. This mixture is then transported through pipelines to the nozzle of the wet shotcrete robot. After the addition of a quick-setting agent, the concrete is sprayed at high speed onto the target area, where it quickly hardens to form a concrete support layer. The wet shotcrete robot can spray concrete in any direction within a limited working area via a delivery pipeline. Traditional wet shotcrete robots have poor spraying accuracy. Traditional wet shotcrete robots are semi-automatic and manually operated, resulting in poor precision. Surface smoothness is highly dependent on the operator's skill level, and the thickness and spray volume of the concrete are difficult to control, placing high demands on the operator.
