Detailed implementation mode

[0027] As Figures 1-5 shown, a bridge tensioning and grouting integrated device mainly consists of a moving base 1, a mixing tank 2, a pair of transfer tanks 3, several raw material tanks 4, a feeding support 5 and several convex feeding pipes 6.

[0028] The mixing tank 2 is installed on the moving base 1, the feeding support 5 is installed on the moving base 1, several raw material tanks 4 are connected to the mixing tank 2 through a quantitative feeding structure, a pair of transfer tanks 3 are installed on the moving base 1, and a pair of transfer tanks 3 are connected to the mixing tank 2 and several convex feeding pipes 6 through a transfer diversion structure.

A number of feeding plates 9 are respectively movably installed on the driving ends of the number of feeding electric push rods 8. A number of feeding return rubber pads 10 are respectively installed inside the number of feeding return pipes 7, and the number of feeding return rubber pads 10 are respectively connected to the number of feeding plates 9. A number of concave sealing limit slides 11 are respectively installed opposite to the bottoms of the number of raw material boxes 4. A number of sealing plates 12 are respectively movably inserted inside the number of concave sealing limit slides 11, and the number of sealing plates 12 are respectively movably inserted on the number of feeding return pipes 7. A number of feeding sealing hydraulic push rods 13 are respectively installed at the bottoms of the number of raw material boxes 4, and the driving ends of the number of feeding sealing hydraulic push rods 13 are respectively connected to the number of sealing plates 12. A number of feeding drainage pipes 14 are respectively inserted into the number of feeding return pipes 7 and the mixing tank 2.

[0031] During use, through the telescopic movement of the feeding sealing hydraulic push rod 13, the sealing plate 12 on the driving end is driven, so that the sealing plate 12 expands and contracts along the inside of a pair of concave sealing limit slides 11 on the side wall, so as to contract the sealing plate 12 blocking between the feeding return pipe 7 and the raw material box 4, so as to drain the raw materials inside the raw material box 4 to the inside of the feeding return pipe 7, and drain them to the feeding plate 9 on the driving end of the feeding electric push rod 8. Different raw materials are limited and collected through the feeding plate 9 and the feeding return rubber pad 10. By the telescopic movement of the feeding electric push rod 8, the height of the feeding plate 9 inside the feeding return pipe 7 is changed. By controlling the volume of the feeding, the feeding of raw materials according to different requirements is achieved. When a certain amount is reached, through the telescopic movement of the feeding sealing hydraulic push rod 13, the sealing plate 12 is inserted into the inside of the feeding return pipe 7 to seal the connection between the feeding return pipe 7 and the raw material box 4. By lowering the feeding electric push rod 8, the raw materials on the feeding plate 9 are drained to the inside of the feeding drainage pipe 14, so as to drain different types of raw materials to the inside of the mixing tank 2.

[0034] During use, the transfer driving motor 15 operates to drive the transfer gear box 16 on the driving end of the transfer driving motor 15 to rotate. The transfer gear box 16 drives the transfer threaded pipe 18 inside it to rotate, causing the transfer threaded rod 17 to lift along the inner side of the transfer threaded pipe 18. Thus, the transfer lifting plate 19 on it is driven by the lifting threaded rod to lift, so as to generate negative pressure inside the transfer box 3, thereby draining the stirred raw materials inside the mixing box 2 to the inside of the transfer box 3. The pair of three-way control valves are used to control the connection between the pair of transfer boxes 3 and the mixing box 2.

Through the lifting stirring gearbox 29, the lifting stirring shaft 28 therein is driven, so as to rotate the lifting stirring shaft 28 horizontally and stretch it vertically. Through the lifting and rotation of the lifting stirring shaft 28, several lifting stirring blades 30 thereon are driven to rotate horizontally and stretch vertically, so as to stir and mix the inside of the stirring tank 2, avoiding the phenomenon of blockage.
