DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.
[0025] Embodiment one:
[0026] A kind of concrete mixing device for bridge maintenance, as shown in Figures 1-5 Fig. 1, the side of blender 1 is connected with guide mechanism 3 by conveying pipe 2, guide mechanism 3 includes guide frame 301, slidingly connected with sliding frame 302 on guide frame 301, sliding groove 303 is formed in the side of guide frame 301, the both ends of sliding groove 303 are fixedly connected with thrust spring 304, one end of thrust spring 304 is fixedly connected with sliding rod 305, the bottom of sliding rod 305 is fixedly connected with sealing plate 306, guide plate 307 is rotatably connected on sliding rod 305, guide mechanism 3 makes that concrete mixture can be accurately filled into the groove opened on both sides of bridge expansion joint, the sliding connection of sliding frame 302 on guide frame 301 and the cooperation of thrust spring 304 and sliding rod 305 make that sealing plate 306 can be closely attached to the both sides of expansion joint steel frame, effectively prevent concrete mixture from pouring into expansion joint inside, so that the normal function of expansion joint is guaranteed not to be affected.
[0027] Referring to Figure 2 , the top of sliding frame 302 is provided with empty slot 308, the both ends of the top of guide frame 301 are fixedly connected with locking mechanism 4, the addition of locking mechanism 4 makes that construction personnel can conveniently adjust the position of sliding frame 302 on guide frame 301, and is locked at the appropriate position according to actual needs.
[0028] Referring to Figure 2The locking mechanism 4 includes a vertical plate 401, and a locking cam 402 is rotatably connected to one side of the vertical plate 401. The rotation of the locking cam 402 can also generate sufficient locking force to ensure that the sliding frame 302 will not be displaced due to external force during the pouring process, thereby ensuring the accurate pouring of concrete mixture and construction quality.
[0029] See Figure 2 , Figure 3 and Figure 4 The bottom of both the guide frame 301 and the sliding frame 302 are fixedly connected with scrapers 309. The scrapers 309 can effectively prevent the concrete mixture from overflowing into areas that do not need repair during the pouring process, thereby reducing material waste and the difficulty of cleaning.
[0030] The implementation principle of this utility model is as follows: First, the construction personnel need to slide the sliding frame 302 along the sliding groove 303 of the guide frame 301 to both sides according to the width of the expansion joint, and adjust it to a position that matches the width of the expansion joint. Then, the locking cam 402 is rotated to fix the guide frame 301 and the sliding frame 302. After that, the construction personnel need to pull open the sliding rod 305 so that the sealing plate 306 at the bottom of the sliding rod can tightly abut against both sides of the expansion joint steel frame. The guide plate 307 at the top of the sliding rod will form a roof-like structure at the top of the expansion joint. This structure can effectively prevent grout from flowing into the interior of the expansion joint.
[0031] After adjusting the position of the sliding frame and sliding rod, the construction personnel can start the mixer 1 and output the slurry inside the mixer to the guide mechanism 3 through the delivery pipe 2. The slurry will flow along the guide plate 307 to both sides of the expansion joint. Due to the roof structure of the guide plate, the slurry will not flow into the interior of the expansion joint. Pull the guide mechanism 3 so that the guide mechanism 3 can slide along the steel frame of the expansion joint. At this time, the scraper 309 at the bottom of the guide frame 301 and the sliding frame 302 will ensure that the slurry will not overflow into the area that does not need to be repaired during the flow process.
[0032] After the grout is poured, the construction workers remove the equipment and then use a vibrator to compact it. Once the grout has solidified, the repaired expansion joint can be inspected and cleaned as necessary.
[0033] Example 2:
[0034] See Figure 5 The sliding frame 302 is provided with sliding wheels 5 on both sides. The bottom of the sliding wheels 5 and the scraper 309 are at the same level, which ensures that the scraper 309 can always maintain contact with the ground during movement, thereby avoiding the overflow problem caused by shaking or jumping and reducing subsequent cleaning steps.
[0035] The implementation principle of this utility model is as follows: First, by setting the sliding wheel 5, the resistance can be further reduced and the convenience of pulling can be improved when the guide mechanism 3 is dragged to slide.
