Detailed Embodiments

[0023] Embodiment 1

[0024] As Figures 1-3 shown, a self-compacting concrete pouring support proposed in this embodiment includes a feed hopper 1, a discharge direction adjusting mechanism, two movable chute mechanisms, two blanking hoppers 6, two groups of hoisting mechanisms and two groups of power components b.

[0025] A blanking pipe 4 is connected to the feed hopper 1, and an electric valve 5 is installed on the blanking pipe 4; a support 2 is arranged at the bottom end of the feed hopper 1, and a plurality of rollers 3 are installed at the bottom end of the support 2.

[0026] The discharging direction adjusting mechanism is installed on the support 2 for adjusting the discharging direction. The discharging direction adjusting mechanism includes a distributing chute 16, a servo motor d17, and a rotating plate 18. The distributing chute 16 is fixedly connected to the support 2. The distributing chute 16 is located below the blanking pipe 4. The distributing chute 16 has an inverted "V" structure. The rotating plate 18 is rotatably installed in the middle of the inner side of the distributing chute 16. The servo motor d17 is installed on the distributing chute 16 and its output shaft is connected to the rotating plate 18. By starting the servo motor d17 to work, the rotating plate 18 is driven to rotate, and thus the discharging direction can be controlled. When the rotating plate 18 is vertically arranged, the synchronous discharging work for the two side blanking hoppers 6 can be realized. If the rotating plate 18 is inclined, the bottom end of the rotating plate 18 faces which side, and the material will be discharged into the interior of the blanking hopper 6 on that side.

[0027] Two movable chute mechanisms are symmetrically installed at both ends of the discharging direction adjusting mechanism. The movable chute mechanism includes a discharging chute a7 and a discharging chute b8. The discharging chute a7 is rotatably installed on the discharging direction adjusting mechanism. A power assembly a for driving the discharging chute b8 to expand and contract is connected between the discharging chute a7 and the discharging chute b8. The power assembly a includes a servo motor c141, a threaded rod b142, and a threaded sleeve b143. The servo motor c141 is installed on the side wall of the discharging chute b8. The threaded rod b142 is connected to the output shaft of the servo motor c141. The end of the threaded sleeve b143 is connected to the discharging chute a7. The threaded sleeve b143 is threadedly connected to the threaded rod b142. Sleeves 151 and movable rods a152 are respectively connected to the discharging chute a7 and the discharging chute b8. The end of the movable rod a152 is slidably installed inside the sleeve 151.

[0028] Two blanking hoppers 6 are respectively arranged on both sides of the support 2. A rotating seat 62 is arranged on the blanking hopper 6. The outer end of the discharging chute b8 is rotatably connected to the rotating seat 62. The outer end opening of the discharging chute b8 gradually contracts from inside to outside. The outer end opening of the discharging chute b8 is rotatably installed on the rotating seat 62. With this setting, the concrete discharged through the discharging chute b8 can all fall into the inner side of the blanking hopper 6, avoiding the concrete from falling into the area outside the blanking hopper 6.

[0029] Movable plates 19 are arranged on both sides of the upper end of the support 2. Two sets of hoisting mechanisms are respectively installed on the movable plates 19 on both sides and are respectively used to drive the two side blanking hoppers 6 to lift. The hoisting mechanism includes a servo motor b10, a speed reducer 11, a winding disc 12, and a steel wire rope 13. The servo motor b10 and the speed reducer 11 are both installed on the movable plate 19. The output shaft of the servo motor b10 is connected to the input shaft of the speed reducer 11. The winding disc 12 is installed on the output shaft of the speed reducer 11. One end of the steel wire rope 13 is fixed on the winding disc 12. A fixing frame 61 is connected to the blanking hopper 6. The other end of the steel wire rope 13 is connected to the fixing frame 61.

[0030] Two sets of power components b are both installed on the bracket 2 and are respectively used to drive the movable plates 19 on both sides. The power component b includes a servo motor a91, a threaded rod a92, and a threaded sleeve a93. The servo motor a91 is installed at the upper end of the bracket 2. The threaded rod a92 is connected to the output shaft of the servo motor a91. The end of the threaded sleeve a93 is connected to the corresponding movable plate 19, and the threaded sleeve a93 is threadedly connected to the threaded rod a92. A movable rod b20 is connected to the movable plate 19, and the movable rod b20 is slidably installed horizontally at the upper end of the bracket 2.

[0031] When adjusting the discharging height of the discharging hopper 6, the hoisting mechanism can drive the discharging hopper 6 to lift and lower. At the same time, the power component a drives the discharging chute b8 to move, thereby realizing the adjustment of the telescopic length of the movable chute mechanism and making the discharging hopper 6 in a vertical state. When adjusting the pouring position of the discharging hopper 6 (i.e., the distance between the discharging hopper 6 and the feeding hopper 1), the power component b drives the movable plate 19 to move, thereby driving the hoisting mechanism and the discharging hopper 6 to move. At the same time, the movable chute mechanism is driven to adaptively expand and contract to ensure that the discharging hopper 6 is in a vertical state. In summary, the technical solution can realize the adjustment of the discharging position and height of the discharging hopper 6, and has strong applicability.

[0032] Embodiment 2

[0033] As Figure 3 shown, a self-compacting concrete pouring bracket proposed in this embodiment, compared with Embodiment 1, in this embodiment, the end of the discharging chute a7 is arranged inside the discharging chute b8, and there is a gap between the outer surface of the discharging chute a7 and the inner surface of the discharging chute b8. Through the above setting, the discharging chute a7 does not contact the discharging chute b8, thereby preventing the inner wall of the discharging chute b8 from becoming thick due to the coagulated concrete and causing it to be unable to move smoothly.

[0034] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art to which the present invention pertains.
