Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge accessory structure construction, in particular to a pouring device for lifting curbstones. Background Art

[0002] Under the combined effects of vehicle load, temperature, rain and snow and other factors, as the service life of the highway increases, the concrete pavement or asphalt pavement will inevitably be damaged to varying degrees. When the pavement is damaged to a certain extent, local repair is no longer effective. You can add a layer of asphalt concrete surface layer to the pavement, or crush the old road panels into a base layer, and then add a cement or asphalt concrete surface layer on the base layer. These two methods will raise the road surface to a certain extent, so the curbstone needs to be raised accordingly. The traditional construction method of raising the curbstone is to add templates on both sides of the original curbstone, manually pour concrete on the top surface of the original curbstone, scrape it flat, and finish it, which has low work efficiency. Utility Model Content

[0003] In view of the above problems, the present utility model is proposed to provide a curbstone lifting casting device that overcomes the above problems or at least partially solves the above problems.

[0004] The curbstone lifting casting equipment comprises a mobile trolley, a storage hopper, a spiral feeding mechanism, a discharge hopper, and a scraping device; the storage hopper and the spiral feeding mechanism are both arranged on the mobile trolley, and the discharge hopper is arranged on one side of the mobile trolley; the spiral feeding mechanism comprises a material pipeline, a spiral shaft extending into the material pipeline, and a power mechanism for driving the spiral shaft to rotate; the pipe wall of the material pipeline is formed with a first opening that docks with the discharge port of the storage hopper, and a second opening that opens downward and faces the feed port of the discharge hopper, and the outer peripheral wall of the spiral shaft is formed with spiral blades, and when the spiral shaft rotates, it can cause the concrete contained in the storage hopper to be transferred to the discharge hopper;

[0005] The material pipeline is arranged horizontally and transversely, a bracket is fixed on the outer wall of the material pipeline, the bracket is provided with two guide rails or guide grooves arranged opposite to each other and parallel to the material pipeline, the discharge hopper is overlapped on the guide rails or guide grooves and can slide along the guide rails or guide grooves;

[0006] The scraping device is arranged behind the discharge hopper and fixedly connected to the discharge hopper; the scraping device includes a scraping plate and a collecting plate. The scraping plate is arranged obliquely, and its upper end is fixedly connected to the discharge hopper, and its lower end at the rear is fixedly connected to the horizontally arranged collecting plate.

[0007] In one embodiment, the power mechanism includes a motor, an output end of the motor is sleeved with a first gear, an input end of the spiral shaft extending out of the material pipeline is sleeved with a second gear, and a chain is sleeved between the first gear and the second gear.

[0008] In one embodiment, the mobile cart includes a frame and a handlebar, and the storage hopper and the spiral feeding mechanism are arranged on the frame. The frame is formed with a manned platform for an operator to stand on and located behind the handlebar, and a cargo platform located in front of the storage hopper.

[0009] When the utility model is used for casting equipment for lifting curbstones, during the process of casting concrete on the top surface of the original curbstone, the concrete falls into the discharge hopper and is discharged along the discharge port below the discharge hopper. Since the curbstones are not all arranged in a straight line and the moving trolley has a certain deviation when walking along the set route, the discharge hopper and / or the scraping device are constrained by the templates on both sides of the curbstone. The templates on both sides can cause the discharge hopper to slide adaptively laterally along the guide rails or guide grooves to avoid the moving template and concrete spilling out.

[0010] Compared with the traditional construction method of lifting the curb, the casting equipment using the curb lifting can reduce labor costs while improving the degree of mechanization, greatly improve work efficiency, and achieve rapid maintenance operations.

[0021] A curbstone lifting casting device according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0022] See also Figures 1 to 3According to an embodiment of the utility model, a curbstone lifting casting equipment comprises a mobile trolley 1, a storage hopper 2, a spiral feeding mechanism, a discharge hopper 3, and a scraping device 4. The mobile trolley 1 is used to carry other components of the casting equipment. Specifically, the storage hopper 2 and the spiral feeding mechanism are arranged on the mobile trolley 1, and the discharge hopper 3 is arranged on one side of the mobile trolley 1. The mobile trolley 1 can have its own power system and walk along a set route close to the original curbstone during the process of pouring concrete on the top surface of the original curbstone.

[0023] The storage hopper 2 can be fixed on the mobile trolley 1 through a fixing frame 5. The storage hopper 2 is formed with a feed port at the top and a discharge port at the bottom, and concrete can be stored in the storage hopper 2. The spiral feeding mechanism includes a material pipeline 6, a spiral shaft 7 extending into the material pipeline 6, and a power mechanism for driving the spiral shaft 7 to rotate. The pipe wall of the material pipeline 6 is formed with a first opening 8 that docks with the discharge port of the storage hopper 2, and a second opening 9 that opens downward and faces the feed port of the discharge hopper 3. In order to avoid concrete leakage, the lower end of the storage hopper 2 and the material pipeline 6 can be sealed by welding, and the concrete stored in the storage hopper 2 can flow into the first opening 8 by the action of its own gravity. The outer peripheral wall of the screw shaft 7 is formed with a screw blade, and when the power mechanism drives the screw shaft 7 to rotate, it can cause the concrete contained in the storage hopper 2 to be transferred to the discharge hopper 3. Specifically, after the concrete in the storage hopper 2 enters the first opening 8, it is driven by the screw shaft 7 to move along the material pipe 6 toward the second opening 9, and then leaves the second opening 9 and falls into the discharge hopper 3 located below the second opening 9. The screw shaft 7 can also play the role of mixing concrete.

[0024] The material pipeline 6 is arranged horizontally and transversely, and a bracket 10 is fixed to the outer wall of the material pipeline 6. The bracket 10 is provided with two guide rails or guide grooves arranged opposite to each other and parallel to the material pipeline 6. The discharge hopper 3 is overlapped on the guide rails or guide grooves and can slide along the guide rails or guide grooves. During the process of pouring concrete on the top surface of the original curb, after the concrete falls into the discharge hopper 3, it is discharged along the lower end discharge port of the discharge hopper 3. Since the curbs are not all arranged in a straight line, and the moving trolley 1 has a certain deviation when walking along the set route, the discharge hopper 3 and / or the scraping device 4 are constrained by the templates on both sides of the curb. The templates on both sides can cause the discharge hopper 3 to slide adaptively and transversely along the guide rails or guide grooves to avoid the mobile template and concrete spilling.

[0025] The scraping device 4 is arranged behind the discharge hopper 3 and is fixedly connected to the discharge hopper 3. The scraping device 4 includes a scraping plate 11 and a collecting panel 12. The scraping plate 11 is arranged obliquely, and its upper end is bolted to the discharge hopper 3, and its lower end at the rear is fixedly connected to the horizontally arranged collecting panel 12. Concrete falls from the discharge hopper 3 to the top surface of the original curb, and then the scraping plate 11 moves with the mobile trolley 1 to the place where the concrete falls to scrape the concrete flat, and then the collecting panel 12 performs the surface finishing work. The scraping plate 11 and the collecting panel 12 can be bent from the same metal plate. In the actual construction process, scraping devices 4 of different specifications can be selected according to the required lifting height of the curb and the width of the curb.

[0026] In this embodiment, the power mechanism includes a motor 13, the output end of the motor 13 is sleeved with a first gear 14, end covers, bearings, etc. are set at both ends of the material pipeline 6, and the input end of the spiral shaft 7 extending out of the material pipeline 6 is provided with a second gear 15, and a chain is sleeved between the first gear 14 and the second gear 15.

[0027] The mobile vehicle 1 includes a frame 16 and a handlebar 17. The storage hopper 2 and the spiral feeding mechanism are arranged on the frame 16. The frame 16 is formed with a manned platform 18 for operators to stand on and located behind the handlebar 17, and a loading platform 19 located in front of the storage hopper 2. The staff can stand on the loading platform 19 to pour concrete or concrete raw materials into the storage hopper 2.

[0028] Compared with the traditional construction method of lifting the curb, the curb lifting casting equipment of this embodiment can reduce labor costs while improving the degree of mechanization, greatly improve work efficiency, and realize rapid maintenance operations.
