Description

Technical Field

[0001] The utility model relates to the technical field of concrete distribution, in particular to a precise concrete distribution device for preparing shield segments. Background Art

[0002] Shield segments are precast concrete components used to line tunnels during shield construction. The production process generally includes the following steps: steel cage production, mold preparation, steel cage placement, concrete pouring, curing, and demoulding. Concrete is usually laid in the operation room. After the steel cage is placed in the mold, the mold is moved to the bottom of the storage barrel in the operation room. The top cover is then moved to the top of the mold and pressed tightly. Then, a certain amount of concrete from the storage barrel is poured into the mold for concrete laying.

[0003] The above-mentioned and existing related technologies often have the following defects: the storage barrel generally prepares a certain amount of concrete through a feeding pipe, and the concrete material has a certain viscosity after mixing. Although the feeding pipe inputs the certain amount of concrete into the storage barrel, after the storage barrel pours the concrete into the mold, the inner wall of the storage barrel is easily adhered to the concrete, making some concrete difficult to pour out directly. After a long time, it is easy to harden inside the storage barrel, resulting in the inability to accurately prepare the amount of concrete in the mold, which affects the quality of the pipe segment and reduces the yield of the pipe segment.

[0004] To this end, we propose a precise concrete distribution device for shield segment preparation. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1 When the material is in the working state, the lifting of the lifting mechanism 7 and the lifting of the lifting mechanism 7 are both effective.

[0031] The specific configuration and function of the scraping structure 7 and the limiting structure 8 will be described in detail below.

[0032] like Figure 2 and Figure 3 as well as Figure 4The top of the handle 7 is fixedly provided with a toothed plate 74, and the toothed plate 75 is fixedly provided with a toothed plate 76, which is in a state of being pushed and pulled out of the handle 76. When the handle 7 is lifted, the toothed plate 76 is pushed and the toothed plate 76 is pushed out of the handle 76. When the handle 7 is lifted, the toothed plate 76 is pushed and the toothed plate 76 is pushed out of the handle 76. The liquid dripping from the delivery pipe 4 can be scraped back into the storage barrel 3 to avoid it from being retained on the upper surface of the scraper ring 71 as much as possible. The lower surface of the scraper ring 71 is fixedly connected with an arc bar 77, and the arc surface of the arc bar 77 is fixedly connected with a number of convex balls 78. The arc bar 77 drives the several convex balls 78 to scrape the residual concrete through the scraper ring 71. The convex balls 78 prevent a small amount of concrete from adhering to the surface of the scraper ring 71 again. The several convex balls 78 are evenly fixed on the arc surface of the arc bar 77. The inner wall of the connecting frame 72 is evenly fixed with two stress rods 79. The connecting frame 72 drives the two stress rods 79 to move, and the stress rods 79 serve to improve the supporting strength between the connecting frame 72 and the support rod 73.

[0033] like Figure 2 and Figure 5 As shown, the limiting structure 8 includes two brackets 81, the lower surfaces of the two brackets 81 are fixedly connected to the storage barrel 3, the upper surface of the bracket 81 is fixedly connected to an L-shaped plate 82, the short arm of the L-shaped plate 82 is threaded with a driving rod 83, one end of the driving rod 83 is rotatably connected to a limiting block 84, the surface of the limiting block 84 is slidably connected to a sliding frame 85, the lower surface of the sliding frame 85 is fixedly connected to the long arm of the L-shaped plate 82, both sides of the multi-stage telescopic cylinder 75 are fixedly connected to a card frame 86, the surface of the limiting block 84 is slidably connected to the inner wall of the card frame 86, and the bracket A hook plate 87 is fixedly connected to one side of 81, and the inner wall of the hook plate 87 abuts against the arc surface of the multi-stage telescopic cylinder 75. The multi-stage telescopic cylinder 75 moves into the hook plate 87. The hook plate 87 guides the multi-stage telescopic cylinder 75 to the center position in advance when it is installed. A positioning plate 88 is fixedly connected to the upper surface of the hook plate 87. One side of the positioning plate 88 abuts against the multi-stage telescopic cylinder 75. The multi-stage telescopic cylinder 75 fits against the inner wall of the hook plate 87 and then fits against one side of the positioning plate 88. The positioning plate 88 prevents the multi-stage telescopic cylinder 75 from rotating.

[0034] Working principle: When it is necessary to prepare the shield segments, first the multi-stage telescopic cylinder 75 is installed above the storage barrel 3 through the limiting structure 8, and then the steel cage is placed in the mold 1. After the mold 1 is transported to the operating room, it is located below the storage barrel 3. The top cover 2 is then moved to the top of the mold 1 through the driving frame and clamped after being fitted. At this time, the feeding pipe 4 inputs the quantitative concrete into the storage barrel 3 in advance, and then the bottom plate 6 is driven by the motor 5 to rotate. During the rotation of the bottom plate 6 from the lower surface of the storage barrel 3, the concrete adhered to the surface is hung on the inner wall of the storage barrel 3. At this time, the concrete in the storage barrel 3 is poured out and poured into the mold 1 through the top cover 2, and then the multi-stage telescopic cylinder 75 is started. The multi-stage telescopic cylinder 75 is fixed by the limiting structure 8 to make the output end drive the support rod 73 to descend. The support rod 73 drives the connecting frame 72 to move with the help of two clamping plates 74, and the connecting frame 72 drives the two stress rods 79 to move. The stress rod 79 serves to improve the connection frame 72 and the support rod 7 The scraper ring 71 is lifted and the scraper bar 76 is lifted to discharge the residual liquid through the scraper ring 71. The scraper bar 76 plays the role of avoiding the liquid from being retained on the upper surface of the scraper ring 71 as much as possible. After the motor 5 drives the bottom plate 6 to reset, the feed pipe 4 feeds a fixed amount of concrete into the storage barrel 3 again, and the mold 1 is vibrated by the internal vibrating mechanism. After the top cover 2 and the mold 1 are separated, the mold 1 is moved out of the operating room and the new mold 1 is moved to the bottom of the storage barrel 3 again, so as to carry out the circulation preparation of the shield segment.

[0035] When the multi-stage telescopic cylinder 75 needs to be installed, the multi-stage telescopic cylinder 75 is first moved to the inner wall of the hook plate 87. The hook plate 87 serves to guide the multi-stage telescopic cylinder 75 to the central position in advance when it is installed. At this time, one side of the multi-stage telescopic cylinder 75 is in contact with the positioning plate 88, and the positioning plate 88 prevents the multi-stage telescopic cylinder 75 from rotating. Then, the driving rod 83 is rotated to the side close to the multi-stage telescopic cylinder 75 through the short arm of the L-shaped plate 82, and the limit block 84 slides from the sliding frame 85 to the card frame 86 through the driving rod 83, thereby limiting the multi-stage telescopic cylinder 75, thereby completing the installation of the multi-stage telescopic cylinder 75 after maintenance and cleaning.
