Description

Technical Field

[0001] The utility model relates to the technical field of concrete recycling, in particular to a device for recycling residual concrete in bridge construction. Background Art

[0002] In order to save construction time, many large bridges are constructed using precast beams. However, due to site and cost limitations, such as the inability to transport precast beams into mountainous canyons or the high cost of transporting precast beams for small bridges, small and medium-sized bridges and mountain bridges are often constructed using cast-in-place concrete.

[0003] The quantity of ready-mixed concrete has been reasonably calculated, but even so, there are often situations where the concrete pouring has been completed but the ready-mixed concrete has not been used up. Since the concrete strength used in bridges is relatively high, often reaching a strength of C30 or above, if the remaining concrete is discarded at this time, it will cause unnecessary waste of raw materials, so it needs to be collected for use in other ancillary projects (such as repairing temporary roads, etc.).

[0004] Concrete is easy to solidify when it is left at rest, but the remaining amount of ready-mixed concrete is usually not large. If the concrete mixing plant is kept in operation, it will cause waste of machinery and electricity. In addition, since the amount of concrete required in some parts of the ancillary projects is small, if the speed and flow of concrete feeding cannot be controlled, it will easily cause excessive waste.

[0005] In order to solve the above problems, we have made improvements and proposed a device for recycling concrete waste materials in bridge construction. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-4 As shown, a device for recovering residual concrete in bridge construction includes a device body 1, an insulation layer 2 is installed inside the device body 1 to insulate the concrete inside the device body 1 to prevent it from being accelerated solidification by the influence of the high temperature of external construction, a central rotating shaft 5 is rotatably installed on the inner bottom surface of the device body 1, a plurality of scrapers 4 and crushing blades 7 are fixedly installed on the outer surface of the central rotating shaft 5, a reinforcement ring 9 is coaxially fixedly installed on the outer surface of the central rotating shaft 5, two discharge ports 14 are fixedly installed on the outer bottom surface of the device body 1, a rotating plate 16 is rotatably installed in the discharge port 14, and a transmission gear 19 and a driving gear 20 are rotatably installed on the outer surface of the device body 1.

[0023] A secondary rotating shaft 6 is fixedly installed on the upper surface of the scraper 4, and a plurality of baffles 8 are fixedly installed on the outer surface of the secondary rotating shaft 6. The scraper 4 contacts the inner bottom surface of the device body 1, and the reinforcement ring 9 is slidably connected to the inner surface of the device body 1. The bottom of the reinforcement ring 9 is fixedly connected to the top of the secondary rotating shaft 6 to prevent the baffle 8 from encountering excessive resistance when rotating inside the device body 1, causing deformation of the secondary rotating shaft 6. The baffle 8 stirs the concrete to prevent it from solidifying, and the crushing blade 7 breaks up small pieces of solid solidified inside the concrete by rotating.

[0024] A material inlet 13 is provided at the top of the device body 1, and a first servo motor 11 and a water tank 12 are fixedly installed on the outer top surface of the device body 1. The rotating shaft of the first servo motor 11 is coaxially fixedly connected with the central rotating shaft 5 to drive the central rotating shaft 5 to rotate. The water outlet of the water tank 12 penetrates downward through the upper surface of the device body 1 and is connected with the interior of the device body 1, so that water can be added to the inside of the device body 1 at any time to improve the fluidity of concrete and slow down its solidification speed.

[0025] Both discharge ports 14 are connected to the interior of the device body 1. A fixing frame 15 is fixedly installed on the inner surface of the discharge port 14. A rubber ring is fixedly installed on the inner surface of the fixing frame 15. A rotating plate 16 is rotatably connected to the inner surface of the fixing frame 15. A rotating rod 17 is coaxially fixedly installed on the side wall of the rotating plate 16. The outer diameter of the rotating plate 16 is consistent with the inner diameter of the fixing frame 15. When the rotating plate 16 is rotated to match the inside of the fixing frame 15, the concrete inside the device body 1 is blocked by the rotating plate 16 and cannot flow out. The flow rate of the concrete discharge can be controlled by rotating the rotating plate 16 to adjust the gap between it and the fixing frame 15.

[0026] The rotating rod 17 is rotatably connected to the discharge port 14 and the fixed frame 15. The ends of the two rotating rods 17 are coaxially fixedly installed with adjusting gears 18. The rotation of the adjusting gears 18 can drive the rotating rods 17 to rotate, thereby adjusting the rotation angle of the rotating plate 16. A reinforcement piece is fixedly installed on the outer bottom surface of the device body 1, and the rotating rod 17 is rotatably connected to the reinforcement piece.

[0027] A motor frame 10 is fixedly mounted on the outer surface of the device body 1, and a second servo motor 21 is fixedly mounted on the outer surface of the motor frame 10. The rotating shaft of the second servo motor 21 is coaxially fixedly connected with the driving gear 20, the driving gear 20 is meshed with the transmission gear 19, and the transmission gear 19 is meshed with both adjusting gears 18. The second servo motor 21 drives the driving gear 20 to rotate, and the rotation of the transmission gear 19 drives the adjusting gear 18 to rotate synchronously.

[0028] A push handle 3 and several support frames are fixedly installed on the outer surface of the device body 1, and universal wheels with brakes are fixedly installed at the bottom of the support frames, which is convenient for operators to move the device to the place where concrete needs to be poured, or push its concrete to the vicinity of a concrete truck for easy recovery.

[0029] Working principle: When using this bridge construction concrete waste recycling device, the remaining concrete from the construction is poured into the device body 1 from the feed port, the first servo motor 11 drives the central shaft 5 to rotate, the scraper 4 contacts the inner bottom surface of the device body 1, and scrapes off the concrete adhering to the inner wall of the device body 1 to prevent it from solidifying, the baffle 8 stirs the concrete to prevent it from solidifying, and the crushing blade 7 breaks up the small solid pieces of concrete inside the concrete by rotating. When the viscosity of the concrete is too high, the water tank 12 adds water to the inside of the device body 1 to improve the fluidity of the concrete and slow down its solidification speed;

[0030] The second servo motor 21 drives the driving gear 20 to rotate, and the transmission gear 19 rotates to drive the adjusting gear 18 to rotate synchronously. The adjusting gear 18 rotates to drive the rotating rod 17 to rotate to adjust the rotation angle of the rotating plate 16. When the rotating plate 16 fits inside the fixing frame 15, the concrete inside the device body 1 is blocked by the rotating plate 16 and cannot flow out. The rotating plate 16 is rotated to adjust the gap between it and the fixing frame 15 to control the flow rate of the concrete discharge.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
