Detailed Description

The utility model is described in further detail below with reference to the drawings and specific examples.

Example one

Fig. 1 to 3 show an embodiment of an inverted arch distributing system according to the present invention, which includes a conveying pipe 1 and a distributing support 2, wherein a set of distributing components are respectively disposed on left and right sides of the distributing support 2, each distributing component includes a rotary distributing pipe 3 and a plurality of pouring pipes 4, the conveying pipe 1 is connected to an inlet of one of the rotary distributing pipes 3, upper ends of the pouring pipes 4 are located on a rotation path of an outlet of the rotary distributing pipe 3 (i.e., upper ends of the pouring pipes 4 are arranged along a circumferential direction), and lower ends of the pouring pipes 4 are pouring openings. In other embodiments, a material distribution assembly may be disposed on only one side of the material distribution frame 2, which may simplify the structure and has a disadvantage in that the inverted arch material distribution system can only complete one-side inverted arch casting at one time.

This inverted arch cloth system, the lower extreme of each pouring pipe 4 is arranged with the inverted arch pouring point that sets for respectively as pouring the mouth, rotatory distributing pipe 3 can dock through the rotation with the upper end of each pouring pipe 4, during the cloth, the concrete that the concrete mixer truck transported over is carried to rotatory distributing pipe 3 through conveyer pipe 1, rotatory distributing pipe 3 carries the concrete to the upper end of pouring pipe 4, the concrete pours to the point of pouring from the lower extreme of pouring pipe 4 under the action of gravity, after pouring of this department is accomplished, rotatory distributing pipe 3 rotates, dock with the upper end of next pouring pipe 4, so repeatedly, can accomplish the pouring of all pouring points (for example according to the pouring of clockwise rotation or clockwise rotation completion whole inverted arch). This invert cloth system simple structure, convenient operation, the efficiency of construction is high, combine many through the rotation of rotatory distributing pipe 3 to pour pipe 4, realize invert layer concrete placement area's full coverage, degree of automation is high, has saved the operation that the chute was removed in the past to the manual work, has reduced intensity of labour, and concrete mixer truck also need not to occupy landing stage 10, makes things convenient for other vehicles, equipment normally to pass through landing stage 10, makes each construction process link up inseparabler.
