Description

Technical Field

[0001] The utility model relates to the technical field of plugging devices, in particular to a plugging device for anchor bar holes of high-cold hydraulic structures. Background Art

[0002] Hydraulic structures refer to artificial buildings or facilities used to regulate, utilize and control water resources. They are mainly used for the storage, regulation, supply, discharge and utilization of water resources. Anchor bars are often used in hydraulic structures. When installing anchor bars, holes must be drilled first. After drilling, the holes must be cleaned and filled with mortar. Finally, the anchor bars are inserted into the holes and fixed after the mortar solidifies. In high-altitude cold areas, due to the low temperature, the early strength development of concrete may be inhibited, which prolongs the solidification time of the mortar. As the construction time increases, the risk of accidental impact of the anchor bars before the mortar solidifies will undoubtedly increase, resulting in gaps between the anchor bars and the mortar after the impact, affecting the reliability and stability of the anchoring system. In view of this, the utility model proposes a device for sealing anchor bar holes in high-altitude cold hydraulic structures. Utility Model Content

[0027] Example

[0028] like Figure 1-3As shown, the utility model proposes a device for plugging anchor holes of high-cold hydraulic structures, comprising two groups of symmetrically arranged shells 1, which can be semi-cylindrical hollow or rectangular hollow. The top of one group of shells 1 is also connected to a grouting machine and a pressurizing device through a connecting pipe 2, so as to inject new mortar into the gap between the anchor and the solidified mortar, and to facilitate the mortar to flow into the gap after pressurization. The tops of the two groups of shells 1 are both provided with mounting sleeves 11 on the sides close to each other, and a sealing cushion 12 is installed in the mounting sleeve 11, which is used to clamp the two groups of shells 1 on the anchor when the sealing cushion 12 is close to each other, so as to increase the sealing performance. The bottoms of the two groups of shells 1 are respectively provided with sealing rings 13, and the sealing rings 13 are pressed to improve the sealing performance when downward pressure is applied to the shells 1. The downward pressure can be applied by placing a heavy object or by pushing a hydraulic cylinder. The two ends of the two groups of sealing rings 13 can be set to a step-like setting that cooperates with each other, so as to prevent the gap at the joint from affecting the air tightness after splicing. A groove 14 is provided on one side of the housing 1 of one group close to the other housing 1, and a protrusion 15 matching the groove 14 is installed on the side of the other housing 1, so that the two housings 1 can be matched and connected together to improve the sealing performance. A sealing gasket 16 is also installed in the groove 14, and the sealing gasket 16 is pressed by the protrusion 15 when the two housings 1 are close to each other, so as to further improve the sealing performance.

[0029] Specifically, the blocking device further includes a fixing mechanism 3 for driving the two groups of shells 1 to approach each other to clamp the anchor bars. The fixing mechanism 3 includes a synchronization plate 31, a limiting sleeve 32, a connecting plate 33, and a fixing plate 34. The two groups of L-shaped synchronization plates 31 are respectively fixedly connected to the sides of the two groups of shells 1, and the shells 1 and the synchronization plates 31 move synchronously. Multiple groups of reinforcing ribs are also fixedly connected between the synchronization plates 31 and the shells 1, so that the fixation between them is firm. The two groups of limiting sleeves 32 are respectively slidably connected to the two groups of synchronization plates 31, and the synchronization plates 31 move under the limiting action of the limiting sleeves 32. Multiple groups of connecting plates 33 are fixedly connected to the side of the limiting sleeves 32 away from the shell 1, and the U-shaped fixing plate 34 is fixedly connected to one end of the multiple groups of connecting plates 33 away from the limiting sleeves 32. The fixing plate 34 is connected to the limiting sleeves 32 as a whole through the connecting plate 33. The fixing mechanism 3 further includes a push rod motor 35, a slide bar 36, a sliding sleeve 37, and a connecting rod 38. The push rod motor 35 is installed on the side of the fixing plate 34 away from the housing 1. The output end of the push rod motor 35 passes through the fixing plate 34 and is fixedly connected to the slide bar 36. The push rod motor 35 is used to drive the slide bar 36 to move after starting. The fixing mechanism 3 also includes two sets of limit rails 39 fixedly connected to the fixing plate 34. The slide bar 36 is slidably connected to the two sets of limit rails 39, so that the movement of the slide bar 36 is stable. Both sets of sliding sleeves 37 are slidably connected to the slide bar 36. When the slide bar 36 moves, it drives the two sets of sliding sleeves 37 to move synchronously. Two groups of connecting rods 38 are rotatably connected to the two groups of sliding sleeves 37, and one end of the two groups of connecting rods 38 away from the sliding sleeves 37 is rotatably connected to the limit sleeves 32 and the fixed plate 34, so that the sliding sleeves 37 drive the two groups of connecting rods 38 to deflect when moving, and at the same time, the sliding sleeves 37 slide on the sliding rods 36, and the synchronous plate 31 slides in the limit sleeves 32.

[0030] In this embodiment, when there is a gap between the anchor bar and the solidified mortar, the two sets of housings 1 are placed on both sides of the anchor bar, the push rod motor 35 is started to extend, and the slide rod 36 is driven to approach the housing 1. At the same time, the slide rod 36 moves smoothly under the limiting action of the two sets of limit rails 39. At this time, the slide rod 36 drives the two sets of sliding sleeves 37 to approach the housing 1, and the sliding sleeves 37 drive the two sets of connecting rods 38 to deflect, and the angle between the two sets of connecting rods 38 gradually increases. At the same time, the two sets of sliding sleeves 37 slide on the slide rod 36 and approach each other. At this time, the connecting rod 38 drives the two sets of synchronous plates 31 to approach each other when it deflects. The two sets of synchronous plates 31 approach each other under the limiting action of the limit sleeve 32, and at the same time, the two sets of housings 1 are driven to approach each other. When the two sets of sealing cushions 12 just contact the anchor bar, the push rod motor 35 is stopped. At this time, a heavy object is pressed on the housing 1, so that the sealing ring 13 is squeezed to increase the sealing performance. The push rod motor 35 is started again to extend, so that the two sets of housings 1 continue to approach each other, and at the same time, the two sets of sealing pads 12 squeeze the anchor bar, and the protrusion 15 enters the groove 14 to squeeze the sealing pad 16, further improving the sealing. Finally, mortar is poured into the housing 1 through the connecting pipe 2, and a certain pressure is applied at the same time, so that the mortar can better enter the gap between the anchor bar and the solidified mortar, thereby improving the reliability and stability of the anchoring system.

[0031] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
