SAFE OPERATION SYSTEM AND SAFE OPERATION METHOD FOR EQUIPMENT FOR SUPPLYING CONCRETE

摘要

The present invention provides a safe operation system for equipment for supplying concrete, comprising: a plurality of pressure sensors spaced apart from each other along the lengthwise direction of a concrete supply pipe to sense the internal pressures of the supply pipe at the respective locations of the sensors; a memory unit, which stores normal operation pressure range information or normal operation pressure variation information at the respective locations of the sensors; and a control unit which compares the internal pressures sensed by the pressure sensors and the normal operation pressure range information stored in the memory unit after starting the operation of the concrete pump, which determines whether or not the interior of the concrete supply pipe is clogged, and which stops the operation of the concrete pump when one or more internal pressures sensed by the pressure sensors or a variation in one or more internal pressures exceed a normal operation pressure range or are lowered to a level below a normal operation pressure variation range. As the internal pressures or internal pressure variation of the concrete supply pipe are monitored on a real-time basis by the pressure sensors arranged on the concrete supply pipe, clogging or clogged points of the concrete supply pipe can be detected in a quick and accurate manner, and the clogging of the pipe can be estimated and examined in advance, thereby preventing or reducing the breakage of the pipe caused by a rise in pressure in the concrete supply pipe, and stably controlling air. In addition, the present invention enables the clogged concrete supply pipe to be replaced alone, thereby reducing repair costs.
