Connection elbow pipe of conveying pipe for concrete pump truck
The invention discloses a connection elbow pipe of a conveying pipe for a concrete pump truck. The connection elbow pipe comprises a first elbow pipe, a straight pipe section and a second elbow pipe, wherein the first elbow pipe is connected to a feeding hole; the second elbow pipe is connected to a discharging hole; the straight pipe section is connected between the first elbow pipe and the second elbow pipe; the first elbow pipe and the second elbow pipe are the same in curvature; each of the first elbow pipe and the second elbow pipe comprises a first arc section, a second arc section and a third arc section; the curvature semi-diameter of the first arc section is the same as that of the second arc section; a straight section tangent to the first arc section and the second arc section is arranged between the first arc section and the second arc section; the curvature semi-diameter of the third arc section is larger than double of the curvature semi-diameter of the second arc section; the third arc section is tangent to the second arc section; the first arc section is connected to the straight pipe section; the third arc section is connected to the feeding hole or the discharging hole. Through the connection elbow pipe, the overall system is more stable; the vibration of a boom system and the conveying pipe can be reduced; the service life of the boom system and the conveying pipe can be prolonged; the energy consumption is reduced.
