Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: a leakage-proof pipeline connecting device for a concrete pump comprises a connecting pipe 1, a fixed pipe 2, a connecting cavity 3, a rubber pad 4, a pressing sheet 5, a bolt 6, a concrete conveying rubber pipe 7, a positioning piece 8, screw holes 9, a connecting port 10, a groove 11 and a lug 12, wherein the fixed pipe 2 is arranged on two sides of the connecting pipe 1, the connecting pipe 1 and the fixed pipe 2 are of an integral structure, four screw holes 9 are respectively arranged on the periphery of the fixed pipe 2, the connecting cavity 3 is arranged in the fixed pipe 2, four pressing sheets 5 are arranged in the connecting cavity 3, the pressing sheets 5 are of an arc-shaped structure, the bolt 6 is rotated to push the pressing sheet 5, the pressing sheet 5 is further used for extruding the concrete conveying rubber pipe 7, and the concrete conveying rubber pipe 7 is tightly attached to the rubber pad 4, compared with the traditional mode, the installation is quicker;

a rubber pad 4 is arranged in the connecting cavity 3, a pressing sheet 5 is arranged on the outer side of the rubber pad 4, bolts 6 are arranged around the fixed pipe 2, a concrete transmission rubber pipe 7 is inserted in the connecting cavity 3, one end of the fixed pipe 2 is connected with a positioning piece 8, the positioning piece 8 is in threaded connection with the fixed pipe 2, and the positioning piece 8 can prevent the connecting cavity 3 in the fixed pipe 2 from being deformed and opened under the action force between the pressing sheet 5 and the concrete transmission rubber pipe 7;
