DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments: First embodiment: See also Figures 1-8 A pouring device for foamed concrete comprises a support platform 1 and a translation frame 19, a mounting frame 2 is fixed on the support platform 1, a conveying cylinder 5 is fixed on the support platform 1, a screw shaft 43 is rotatably installed in the conveying cylinder 5, a transition box 4 is fixed on the conveying cylinder 5 and connected thereto, a conveying pipe 3 is connected and installed on the transition box 4, a plurality of linearly distributed discharge pipes 8 are evenly installed at the bottom of the conveying cylinder 5, a driving assembly for driving the screw shaft 43 to rotate is installed on the support platform 1, a protective cover 7 is installed at the bottom of the support platform 1, and a screw shaft 43 fixed to the protective cover 7 is installed. Two fixed columns 23 are fixed, and a fixed gear 20 is fixedly sleeved on the fixed column 23. A rotating plate 49 is rotatably installed on each fixed column 23. A traction component for driving the rotating plate 49 to rotate is installed in the protective cover 7. An extension sleeve 12 is slidably sleeved on the rotating plate 49. An extension component for driving the extension sleeve 12 to slide relative to the rotating plate 49 is installed on the rotating plate 49. A pair of rotating sleeves 15 are rotatably installed on the bottom of the extension sleeve 12. The two rotating sleeves 15 are connected by a pulley mechanism II29, and a leveling component is installed on the rotating sleeve 15.

[0019] When the foamed concrete is poured on site by this device, the mounting frame 2 is fixed to the external moving device, and the moving device drives the support platform 1 to move through the mounting frame 2, so that the pouring area of ​​the foamed concrete can be adjusted, thereby achieving comprehensive pouring of the pouring site.

[0020] Among them, the external pumping system injects the foamed concrete into the transition box 4 through the delivery pipe 3, and then the foamed concrete enters the middle of the delivery cylinder 5 from the transition box 4. The driving component drives the screw shaft 43 to rotate and transports the foamed concrete inside the delivery cylinder 5. The foamed concrete is discharged to the pouring site area through multiple discharge pipes 8 for pouring.

[0021] Specifically, the driving assembly includes a gearbox 6 fixed on the support platform 1, and two bevel gears 46 fixed coaxially with the spiral shaft 43 are rotatably installed in the gearbox 6. An incomplete bevel gear 44 is rotatably installed in the gearbox 6, and the incomplete bevel gear 44 is alternately engaged with the two bevel gears 46. A dual-axis motor 9 is fixed on the support platform 1, and one output shaft of the dual-axis motor 9 is connected to the incomplete bevel gear 44 through a pulley mechanism I10.

[0022] The dual-axis motor 9 drives the incomplete bevel gear 44 to rotate through the pulley mechanism I10. The incomplete bevel gear 44 is alternately engaged with the two bevel gears 46. Under the transmission action of the bevel gear 46, the spiral shaft 43 can rotate alternately clockwise and counterclockwise, that is, the foamed concrete entering the middle of the conveying cylinder 5 from the transition box 4 can reciprocate relative to the axial direction of the conveying cylinder 5, ensuring that the foamed concrete can be more evenly discharged from multiple discharge pipes 8 to the pouring site, the pouring of the foamed concrete is more uniform, and the pouring quality of the foamed concrete is guaranteed.

[0023] Second embodiment: See also Figures 1-8 In addition to the first embodiment, the traction assembly of this device includes a pin 45 fixed to the translation frame 19. An extension plate 24 is fixed to the end of the rotating plate 49 away from the extension sleeve 12. The extension plate 24 is provided with a strip hole 33, and the pin 45 slidably fits into the strip hole 33. The traction assembly also includes a turntable 11 rotatably mounted on the bottom of the support platform 1. The other output shaft of the dual-axis motor 9 is coaxially fixed to the turntable 11. A slide post 18 is eccentrically hinged on the turntable 11. A circular frame 17 is fixed to the translation frame 19, and the slide post 18 slidably fits into the circular frame 17. A horizontal rod 48 is fixed to the bottom of the support platform 1, and the translation frame 19 is slidably sleeved on the horizontal rod 48.

[0024] Through the above-mentioned setting, while the dual-axis motor 9 drives the pulley mechanism I10, the dual-axis motor 9 drives the turntable 11 to rotate, and the turntable 11 drives the sliding column 18 installed thereon to slide relative to the circular frame 17, so that the circular frame 17 can drive the translation frame 19 to slide back and forth relative to the horizontal rod 48. At this time, the pin 45 on the translation frame 19 drives the extension plate 24 to rotate through the strip hole 33, and the extension plate 24 drives the rotating plate 49 to rotate alternately clockwise and counterclockwise, thereby realizing that the extension sleeve 12 drives the leveling component thereon to move, ensuring that the leveling component fully levels the foamed concrete at the pouring site, effectively improving the pouring effect of the foamed concrete.

[0025] In addition, the extension assembly of the present device includes an intermediate gear 21 and a transmission gear 22 rotatably mounted on a rotating plate 49. The fixed gear 20 and the transmission gear 22 are both meshed with the intermediate gear 21. A rack 51 parallel to the rotating plate 49 is fixed to the extension sleeve 12, and the rack 51 is meshed with the transmission gear 22. The extension assembly also includes a fixed plate 27 fixed to the extension sleeve 12. A vertical plate 25 is fixed to the rotating plate 49. A slide rod 26 that slides through the vertical plate 25 is fixed to the fixed plate 27. A spring coil 28 is sleeved on the slide rod 26, with its ends respectively fixed to the fixed plate 27 and the vertical plate 25. An arc-shaped guide rod 50 is fixed to the bottom of the support platform 1, and the vertical plate 25 is slidably sleeved on the arc-shaped guide rod 50.

[0026] During the process of the rotating plate 49 rotating alternately clockwise and counterclockwise, the rotating plate 49 drives the intermediate gear 21 thereon to rotate around the fixed gear 20. At this time, the intermediate gear 21 rotates and drives the transmission gear 22 to rotate. During the process of the transmission gear 22 rotating alternately clockwise and counterclockwise, the driving rack 51 drives the extension sleeve 12 to slide linearly back and forth relative to the rotating plate 49. Combined with the clockwise and counterclockwise rotation of the extension sleeve 12, the leveling range of the foamed concrete by the leveling component is significantly improved. As the support platform 1 moves, the foamed concrete is fully leveled by the leveling component after being poured into the construction site, which greatly improves the pouring effect of the foamed concrete.

[0027] The leveling assembly includes a sliding post 52 that slides vertically on the rotating sleeve 15. A clip 37, which is slidably embedded in the inner wall of the rotating sleeve 15, is fixed to the sidewall of the sliding post 52. A horizontally arranged leveling plate 13 is fixed to the bottom of the sliding post 52. A drive motor 14 for driving the rotating sleeve 15 is fixed to the extension sleeve 12. An adjustment assembly for driving the vertical movement of the sliding post 52 is installed on the support platform 1. The rotating sleeve 15 is rotated by the drive motor 14, and the rotating sleeve 15 drives the sliding post 52 and the leveling plate 13 to rotate via the clip 37, thereby enabling the leveling plate 13 to rotate and level the foamed concrete.

[0028] Furthermore, the adjustment assembly includes a screw 39 rotatably mounted on the support platform 1, a threaded sleeve 32 being threadedly mounted on the screw 39, a limiting rod 42 being fixed to the bottom of the support platform 1, a guide frame 47 being slidably mounted on the limiting rod 42 being fixed to the threaded sleeve 32, a shifting frame 16 being fixed to the bottom of the threaded sleeve 32, a Y-shaped groove 40 being defined on the shifting frame 16, a connecting frame 31 being engaged within the Y-shaped groove 40, and a sliding post 52 being rotatably mounted on the connecting frame 31. The adjustment assembly also includes a sleeve 30 fixed to the side wall of the rotating sleeve 15, a limiting block 35 being slidably mounted within the sleeve 30, a connecting spring 34 being fixed between the limiting block 35 and the sleeve 30, a plurality of V-shaped slots 38 being vertically defined on the side wall of the sliding post 52 for engaging with the limiting block 35, the V-shaped slots 38 being linearly distributed at equal intervals along the axis of the sliding post 52, and an axial spring 36 being fixed between the sliding post 52 and the rotating sleeve 15. The limiting block 35 is engaged with the V-shaped groove 38 at the corresponding position, so that the sliding column 52 can be slidably adjusted relative to the rotating sleeve 15 to achieve position limitation.

[0029] Through the above setting, in the initial state, the two extension sleeves 12 are in a parallel state, and the connecting frame 31 is clamped in the Y-shaped groove 40. At this time, the height of the connecting frame 31 can be adjusted by the adjustment component, that is, the height position of the sliding column 52 and the leveling plate 13 can be adjusted.

[0030] Specifically, by rotating the screw wheel 41, the screw 39 is driven to rotate, and the screw 39 drives the threaded sleeve 32 threadedly connected thereto to move vertically. At this time, the threaded sleeve 32 drives the shift frame 16 fixed thereto to move vertically, and the shift frame 16 drives the connecting frame 31 to move vertically, thereby realizing that the sliding column 52 drives the leveling plate 13 to move vertically, and the height of the leveling plate 13 is adjusted, that is, the position of the leveling plate 13 can be adjusted according to the pouring thickness of the foamed concrete to adapt to the actual pouring requirements, thereby ensuring that the foamed concrete at the pouring site is fully leveled, and the pouring effect of the foamed concrete is significantly improved.

[0031] In summary, the present invention realizes the transportation of the foamed concrete inside the conveying cylinder 5 by rotating the provided spiral shaft 43, and the incomplete bevel gear 44 in the driving assembly is alternately engaged with the two bevel gears 46, so that the spiral shaft 43 rotates alternately clockwise and counterclockwise, ensuring that the concrete inside the discharge pipe 8 can be evenly discharged through multiple discharge pipes 8 to the foamed concrete, greatly improving the on-site pouring quality of the foamed concrete. The present invention rotates the provided leveling plate 13 to rotate and level the foamed concrete at the pouring site. Under the driving action of the traction assembly, the rotating plate 49 can drive the extension sleeve 12 and the leveling assembly to swing around the center of the fixed column 23, effectively expanding the leveling range of the leveling assembly for the foamed concrete at the pouring site. Under the action of the extension assembly, the extension sleeve 12 can slide back and forth relative to the rotating plate 49, and the on-site pouring effect of the foamed concrete is significantly improved.
