Description

Technical Field

[0002] To give full play to the design effect of the steel strands of prestressed bridges and offset the pressure of vehicles and pedestrians on the bridge deck, the grouting quality effect of prestressed ducts is one of the most important factors. Achieving the designed grouting quality can enable the prestressed steel strands to fully play their role; when there are grouting quality defects, there will be phenomena such as stress concentration at the anchor head and prestress loss over time, and it will change the designed stress state of the beam body, reduce the bearing capacity of the bridge, and thus affect the service life of the bridge. Therefore, the grouting quality detection of prestressed ducts is an important measure to ensure the construction quality of bridges.

[0003] To detect the quality of the slurry, the slurry needs to be repeatedly stirred before the detection.

Specific embodiments

[0029] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0030] In one embodiment, referring to Figures 1 to 8 , a stirring device for prestressed duct grout experiment, including a main box body 1, a controller is installed in the main box body 1, and further includes:

[0031] A stirring pool 8 installed in the main box body 1 for carrying stirring materials;

[0032] A lifting drive structure 3 fixedly connected to the main box body 1, and the lifting drive structure 3 is connected to a rotating stirring structure;

[0033] The rotating stirring structure includes a stirring drive module and an extrusion module. The stirring drive module connected to the lifting drive structure 3 is used to drive the extrusion module to rotate relative to the main box body 1. The extrusion module includes a rotating frame 12 slidably connected to the middle of the stirring drive module. The upper end of the rotating frame 12 limited by the stirring drive module is rotatably connected to the main box body 1. A first driving mechanism 28 is fixedly installed in the rotating frame 12. The output end of the first driving mechanism 28 is fixedly connected to a rotating plate 27. The rotating plate 27 is connected to a plurality of groups of extrusion plate structures through a plurality of groups of linkage structures. A column structure fixedly connected to the stirring pool 8 is rotatably connected to the extrusion plate structure. When the first driving mechanism 28 drives the rotating plate 27 to rotate, the extrusion plate structures cooperate with the linkage structures to achieve the mutual approach of the extrusion plate structures.

[0034] Put the material to be stirred into the stirring pool 8. The lifting drive structure 3 drives the stirring drive module to move, and the stirring drive module drives the rotating frame 12 to rotate synchronously, realizing the rotating stirring of the extrusion plate structure. During the stirring process, the first driving mechanism 28 drives the extrusion plate structure to rotate through the rotating plate 27, and at the same time the linkage structures synchronize the movement of a plurality of groups of extrusion plate structures, so that the extrusion plate structures approach and extrude the slurry from each other. During the use of this device, the extrusion and stirring of the slurry are completed, thereby accelerating the dispersion of the agglomerates formed by the mixture of the material and water, and thus improving the processing effect of the device on the slurry.

[0035] In a case of this embodiment, the stirring drive module includes a tank frame 9 connected to the lifting drive structure 3. The tank frame 9 is connected with a connecting frame 16 rotatably connected to the tank frame 9 through a power transmission module 19. The middle of the connecting frame 16 is slidably connected to the rotating frame 12. The extending ends of the connecting frame 16 are respectively fixedly connected with an outer ring clamping plate 14 and an inner ring clamping plate 15. Both the outer ring clamping plate 14 and the inner ring clamping plate 15 are movably connected to the extrusion plate structure. The material to be stirred is put into the stirring tank 8. The lifting drive structure 3 drives the tank frame 9 to drive the connecting frame 16 to move downward, so as to insert the outer ring clamping plate 14 and the inner ring clamping plate 15 between the extrusion plate structures, fix the distance between the extrusion plate structures, and facilitate controlling the distance between the extrusion plate structures during the stirring of the device and indirectly driving the rotation of the extrusion plate structure through the power transmission module 19.

[0036] In a case of this embodiment, the extrusion plate structure includes an annular body 18 rotatably connected to the columnar structure. The annular body 18 is fixedly connected with an extrusion hole plate 6 rotatably connected to the columnar structure through a connecting piece 17, and the outer side of the extrusion hole plate 6 is slidably connected to the inner wall of the stirring tank 8. When the extrusion hole plate 6 extrudes the slurry, the slurry passes through the spaces between the holes of the extrusion hole plate 6, achieving the effect of filtering the slurry.

[0037] In a case of this embodiment, the linkage structure includes a guide groove 30 opened in the annular body 18. The guide groove 30 is elastically connected with a guide rod structure 20.

And the guide rod structure 20 closest to the rotating plate 27 is rotatably connected to the rotating plate 27, and the guide rod structure 20 farthest from the rotating plate 27 is connected to the columnar structure. Driven by the rotating plate 27, while the guide rod structures 20 squeeze the springs with each other, they drive the extrusion hole plates 6 to approach each other. Springs of the same specification have the same deformation under the action of the same force, achieving the effect of synchronous movement of the extrusion hole plates 6.

[0038] In a case of this embodiment, the columnar structure includes a column 26 and a support ring structure. The support ring structure includes an inner ring 25 fixedly connected to the column 26. A telescopic member 24 is fixedly installed in the inner ring 25. The inner ring 25 is rotatably connected to an outer ring 22.

The outer ring 22 is fixedly connected to a group of annular bodies 18 through a guide rod structure 20, and this group of annular bodies 18 is rotatably connected to the outer ring 22. When it is necessary to make the extrusion hole plate 6 extrude the slurry, the telescopic member 24 extends out and engages with the positioning holes 23 of the outer ring 22, thereby fixing a group of annular bodies 18 connected to the outer ring 22, facilitating the relative rotation between the annular bodies 18.

[0039] In one case of this embodiment, a groove is formed on the side of the column 26 close to the stirring tank 8, and the groove of the column 26 is slidably connected to the inner ring clamping plate 15. The inner ring clamping plate 15 slides along the groove of the column 26, thereby improving the movement accuracy.

[0040] In one case of this embodiment, a material door 10 is hinged to the outside of the main box body 1, and a sealing strip fixedly connected to the material door 10 is installed between the material door 10 and the main box body 1. After the feeding is completed, the material door 10 is covered to block the dust from flying out, and the sealing strip improves the dust blocking effect of the material door 10.

[0041] In one case of this embodiment, an air extraction device 5 is installed in the main box body 1. The air extraction device 5 is connected to a dust collection net pocket 11 installed on one side of the main box body 1, and the dust collection net pocket 11 is detachably connected to the main box body 1. The air extraction device 5 extracts the dust-containing gas and transports it to the dust collection net pocket 11. The dust collection net pocket 11 filters the dust, collects the remaining materials, saves materials, and protects the environment.

[0042] In one case of this embodiment, a water tank 29 is installed on one side of the main box body 1. A pump 2 is fixedly installed in the water tank 29. A cover net 13 is movably installed outside the water suction end of the pump 2, and the water outlet end of the pump 2 extends into the stirring tank 8. The water input into the stirring tank 8 is filtered by the cover net 13 before being input, so as to reduce the impurities carried in the water and protect the slurry.
