Preferably, the connecting pipe and the fixing pipe are of an integral structure, and four screw holes are formed around the fixing pipe.
Preferably, the inside of connecting the chamber is provided with four tight preforming, tight preforming appearance is the arc structure.
Preferably, the positioning piece is in threaded connection with the fixed pipe.
Preferably, the width of the groove is equal to the width of the bump.
Compared with the prior art, the beneficial effects of the utility model are that: the concrete pump is with preventing pipeline connecting device that leaks:
1. through the rotation bolt, the bolt promotes tight preforming, sticiss the piece and then carries out extrusion treatment with the concrete transmission rubber tube, makes the concrete transmission rubber tube hug closely the rubber pad, and this mode is compared with traditional mode, installs more swiftly.
2. Because tight preforming is the arc structure, and sticiss the piece both sides and be provided with recess and lug, the clearance has been avoided appearing between the piece of sticising to mutually supporting between recess and the lug, leads to the condition of cement leakage to this mode compares with traditional mode, and tight preforming is inseparable with concrete transmission rubber tube pressure, has avoided being connected with concrete transmission rubber tube not closely the condition that appears leaking cement.
3. The setting of setting element can prevent under the effort between tight preforming and concrete transmission rubber tube, the inside connecting cavity of fixed tube appears the open condition of deformation.

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;
