Description

Technical Field

[0001] The invention belongs to the technical field of concrete pouring, and specifically relates to a pouring device and a pouring method for green building construction. Background Art

[0002] With the development of society, people's environmental awareness has gradually increased. In the field of construction, people have also begun to pursue green buildings. Among them, prefabricated buildings are particularly in line with the requirements of green buildings. Prefabricated buildings produce and cast building accessories in factories, and then transport them to the site for assembly after maintenance. This can greatly reduce the environmental pollution caused by the production process to the construction site.

[0003] For example, the invention patent with authorization announcement number CN118559859B discloses a concrete precast part casting device in the field of concrete precast part casting technology, including a casting unit for manufacturing precast parts, the casting unit including an inner ring support sleeve vertically arranged and an outer ring support sleeve arranged around the inner ring support sleeve, there is a gap between the outer periphery of the inner ring support sleeve and the inner wall of the outer ring support sleeve, a casting membrane is arranged on the gap, the casting membrane is an annular groove structure, the upper part of the inner ring side of the casting membrane is connected to the upper part of the inner ring support sleeve, the upper part of the outer ring side of the casting membrane is fixedly connected to the upper part of the outer ring support sleeve, and the annular groove structure forms a casting cavity.

[0004] Combining the above cases with actual conditions, we found the following problems: Since concrete includes various aggregates, during actual pouring, concrete will not be continuous like water or viscous liquids. During pouring, some gaps are likely to appear between the internal aggregates, affecting the compactness of the concrete. At the same time, when pouring prefabricated components such as columns or piles, the cross-section of such components is small. If the pouring speed is maintained at the same level, the concrete poured at the top will easily overflow near the top opening of the mold, causing waste. Summary of the invention

[0019] S3. During pouring, the rotating shaft drives the clamping rod to rotate through the transmission rod. When the clamping rod rotates to the spiral groove of the inner groove, it presses down the transmission tube and squeezes the first spring.

When the lower tube rises, the insertion rod squeezes the gas in the gas cylinder, so that the gas passes through the first channel and the second channel to push the extension plate out of the sliding cavity to reduce the gap between the vibrating assembly and the lower tube, thereby slowing down the concrete pouring speed;

[0022] S6. Then repeat the steps S2-S4 to pour the concrete layer by layer until it is completely poured.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, a vibrating assembly is provided, and the servo motor is started to drive the auger to pour. At the same time, the rotating shaft drives the clamping rod to rotate through the transmission rod. When the clamping rod rotates to the spiral groove of the inner groove, the conductive tube is pressed down and the first spring is squeezed. When the clamping rod rotates to the vertical groove, the restoring force of the first spring pushes the conductive tube upward, so that during the discharging process, the conductive tube continuously drives the vibrating plate to vibrate up and down, thereby reducing the gap between the poured concrete, so as to improve the pouring quality of the concrete.

[0025] 2. In the present invention, by setting a baffle structure, after pouring for a period of time, the hydraulic cylinder is started again to drive the lower tube to move up a certain distance. When the lower tube rises, the insertion rod will squeeze the gas in the gas cylinder, so that the gas will push the extension plate out of the sliding cavity through the first channel and the second channel to reduce the gap between the vibrating assembly and the lower tube, thereby gradually slowing down the pouring as the pouring height increases, avoiding excessive concrete pouring and overflowing from the mold when the concrete is close to the mold opening, causing waste.

DETAILED DESCRIPTION

[0041] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0042] Unless explicitly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood as including the stated elements or components but not excluding other elements or components.

[0043] Reference Figure 1-Figure 13 As shown, this embodiment provides a technical solution:

[0044] A pouring device for green building construction, comprising a pouring tank 1 for containing concrete aggregates and a discharging assembly 2 arranged inside the pouring tank 1 for extruding concrete, wherein the discharging assembly 2 comprises a servo motor 21 fixed to the middle of the outer top surface of the pouring tank 1, a rotating shaft 22 coaxially fixed with the output of the servo motor 21, and an auger 23 fixed to the bottom end of the rotating shaft 22, wherein the mixed concrete aggregates are fed into the pouring tank 1 through an opening at the top of the pouring tank 1, and then the servo motor 21 drives the auger 23 to rotate and extrude the material for pouring concrete;

[0045] The pouring tank 1 is composed of a tank body 11, an upper pipe 12, a bellows 13 and a lower pipe 14 which are connected in sequence from top to bottom. The auger 23 is arranged in the upper pipe 12 and the sizes of the two are adapted. A vibrating assembly 3 is arranged in the lower pipe 14. By arranging the vibrating assembly 3, the concrete can be continuously driven to vibrate during the pouring process to reduce the voids in the poured concrete.

[0046] The vibrating assembly 3 includes a fixed tube 31 disposed in the lower tube 14, a shield structure 32 fixed on the top surface of the fixed tube 31, and a vibrating structure 33 disposed in the fixed tube 31. The vibrating structure 33 includes a conductive tube 331, a vibrating plate 333 fixed at the bottom end of the conductive tube 331, and a transmission rod 332 disposed in the conductive tube 331. The vibrating plate 333 is always located below the lower tube 14 to ensure that the vibrating plate 333 can extend into the concrete during pouring.

[0047] The transmission rod 332 includes an upper rod 332a on the upper side and a lower rod 332b on the lower side. The upper rod 332a is coaxially fixedly connected to the bottom end of the rotating shaft 22, and the upper end of the lower rod 332b is inserted into the upper rod 332a and the two are slidably connected. The top of the lower rod 332b is provided with a plurality of regularly distributed flanges 332c. The transmission rod 332 is split into the lower rod 332b and the upper rod 332a, so that when the height of the lower tube 14 is adjusted, the transmission rod 332 is fixed in length and blocks the lower tube 14 from moving up and down. At the same time, the existence of the flange 332c can ensure that the upper rod 332a can drive the lower rod 332b to rotate.

[0048] The bottom end of the lower rod 332b passes through the baffle structure 32 and extends into the conductive tube 331. Two horizontal clamping rods 332d are symmetrically fixed to the bottom end of the lower rod 332b. An inner groove 331b is provided on the inner wall of the conductive tube 331. The outer end of the clamping rod 332d extends into the inner groove 331b. When the upper rod 332a drives the lower rod 332b to rotate, the clamping rod 332d will rotate together, and then drive the conductive tube 331 to vibrate up and down through the inner groove 331b.

[0049] Specifically, Figure 1-Figure 3As shown, the upper tube 12, the bellows 13 and the lower tube 14 are interconnected from top to bottom and the connection is fixed. By setting the bellows 13, the bellows 13 can be driven to synchronously extend and retract when the lower tube 14 moves up and down. A hydraulic cylinder 4 is fixed to the side wall of the upper tube 12, and the output end of the hydraulic cylinder 4 is fixedly connected to the outer wall of the lower tube 14. The hydraulic cylinder 4 is set to drive the lower tube 14 to move up and down to adjust the height. A plurality of regularly distributed annular fixing rods 314 are fixed to the side wall of the fixing tube 31, and the outer ends of the fixing rods 314 are fixed to the outer wall of the lower tube 14. The entire vibrating assembly 3 is fixed by setting the fixing rods 314.

[0050] In addition, if Figure 5-Figure 10 As shown, two groups of mounting plates 311 are symmetrically arranged on the inner wall of the fixed cylinder 31, and the two mounting plates 311 in each group are symmetrically arranged up and down. A limiting rod 312 is fixed between the mounting plates 311 in the same group, and a first spring 313 is sleeved on the limiting rod 312 to drive the conductive cylinder 331 to reset. Hanging ears are symmetrically fixed on the outer wall of the conductive cylinder 331 near the top, and the limiting rod 312 passes through the corresponding hanging ears and the two are slidably connected. The first spring 313 is located below the hanging ears. The rotation of the conductive cylinder 331 can be limited by the limiting rod 312 and the hanging ears, and the first spring 313 can provide elastic force for the position recovery of the conductive cylinder 331.

[0051] Furthermore, the inner groove 331b is composed of four vertical grooves and four arc-shaped spiral grooves connected in an interlaced manner. The number of spiral turns of the spiral groove is a quarter of a circle and the spiral direction is a counterclockwise spiral. The front end of the spiral groove is connected to the top of the front vertical groove, and the rear end is connected to the bottom of the rear vertical groove. When the clamping rod 332d rotates counterclockwise in the spiral groove, since the conductive cylinder 331 cannot rotate, the clamping rod 332d will press the conductive cylinder 331 downward through the spiral groove, so that the conductive cylinder 331 moves downward and squeezes the first spring 313. When the clamping rod 332d rotates to the vertical groove, the first spring 313 will give the conductive cylinder 331 an upward elastic force to drive the conductive cylinder 331 to reset. When the clamping rod 332d rotates continuously with the transmission rod 332, the conductive cylinder 331 will drive the vibrating plate 333 to vibrate up and down continuously.

[0052] In addition, a spatula 34 is provided on the bottom end surface of the lower tube 14, a first clamping block 341 is provided near the middle of the top surface of the spatula 34, a circle of annular groove is provided on the bottom end surface of the lower tube 14, the first clamping block 341 is clamped in the annular groove and the first clamping block 341 can rotate along the annular groove, the spatula 34 can be suspended by the annular groove and the first clamping block 341, a second clamping block 342 is fixed in the middle of the inner side wall of the spatula 34, the inner end of the second clamping block 342 is clamped in the outer arc groove 311a and the two can slide relatively, when the conductive tube 331 vibrates up and down, the second clamping block 342 cooperates with the outer arc groove 311a to drive the spatula 34 to rotate and smooth the poured concrete surface;

[0053] Specifically, an outer arc groove 311a is provided on the outer wall of the conductive cylinder 331. The outer arc groove 311a is in a spiral shape arranged along the outer wall of the conductive cylinder 331 and has one spiral turn. The vertical height from the top to the bottom of the outer arc groove 311a is equal to the height of the vertical groove. When the conductive cylinder 331 vibrates up and down, the outer arc groove 311a will apply a pressure to the second clamping block 342 through the groove wall. When the conductive cylinder 331 moves up, the second clamping block 342 is subjected to the pressure from the upper groove wall and then rotates clockwise along the outer arc groove 311a. When the conductive cylinder 331 moves down, the second clamping block 342 is subjected to the pressure from the lower groove wall and then rotates counterclockwise along the outer arc groove 311a, and at the same time drives the trowel 34 to rotate and smooth the concrete.

[0054] In addition, if Figure 11-13 As shown, the shield structure 32 includes a conical shield plate 321, two air cylinders 322 fixed on the top surface of the shield plate 321, and a plurality of extension plates 323 regularly distributed in an annular shape in the shield plate 321. The shield plate 321 is provided with a plurality of sliding cavities 321a corresponding to the extension plates 323 one by one. The sliding cavities 321a are inclined and have the same inclination as the top surface of the sliding cavities 321a. By providing the shield plate 321, the interior of the fixed cylinder 31 can be shielded to prevent concrete from entering the fixed cylinder 31 and affecting the movement of the vibrating assembly 3.

[0055] Furthermore, an inverted L-shaped plug rod 121 is symmetrically arranged on the inner wall of the upper tube 12 near the bottom, and the vertical section of the plug rod 121 is inserted into the corresponding side cylinder 322. A first annular channel 321b is arranged near the upper part of the baffle plate 321, and the first channel 321b is connected to the bottom end of the cylinder 322. A plurality of second channels 321c distributed in an annular manner are arranged in the baffle plate 321, and the second channels 321c correspond to the sliding cavities 321a one by one, and the second channels 321c are connected to the first channels 321b and the corresponding sliding cavities 321a;

[0056] When the lower tube 14 is moved upward to adjust the height, the distance between the lower tube 14 and the upper tube 12 will decrease, and then the insertion rod 121 will press down the gas in the gas cylinder 322, and the compressed gas enters the sliding cavity 321a through the first channel 321b and the second channel 321c, and then pushes out the extension plate 323. Since the lower tube 14 moves upward, it means that it is closer to the upper opening of the mold. The extension plate 323 is pushed out to reduce the gap between the vibrating assembly 3 and the lower tube 14, thereby slowing down the speed of concrete pouring, avoiding excessive pouring of concrete when pouring concrete close to the upper opening of the mold, resulting in concrete waste;

[0057] In addition, sliding rods 324 are fixed on the left and right side walls of the sliding cavity 321a, and the left and right protruding edges of the bottom end of the extension plate 323 pass through the corresponding sliding rods 324, and the two are slidably connected. A second spring 325 is sleeved on the outside of the sliding rod 324 and located between the extension plate 323 and the ground in the sliding cavity 321a. By setting the second spring 325, the extension plate 323 can be helped to return to the sliding cavity 321a when the lower tube 14 moves downward.

[0058] The present invention also provides a casting method for green building construction, using the above-mentioned casting device for green building construction, comprising the following steps:

[0059] S1, feeding the mixed concrete aggregate into the casting tank 1, and starting the hydraulic cylinder 4 to extend the lower pipe 14 into the mold of the prefabricated structure close to the bottom;

[0060] S2, then close the hydraulic cylinder 4, and start the servo motor 21 to drive the auger 23 to rotate through the rotating shaft 22 to squeeze the concrete aggregate along the corrugated pipe 13 and the lower pipe 14 and pour it into the mold;

[0061] S3. During pouring, the rotating shaft 22 drives the clamping rod 332d to rotate through the transmission rod 332. When the clamping rod 332d rotates to the spiral groove of the inner groove 331b, it presses down the conductive cylinder 331 and squeezes the first spring 313. When the clamping rod 332d rotates to the vertical groove, the restoring force of the first spring 313 pushes the conductive cylinder 331 upward, so that during the discharging process, the conductive cylinder 331 continuously drives the vibrating plate 333 to vibrate up and down, thereby reducing the gap between the poured concrete.

[0062] S4, when the conductive tube 331 vibrates up and down, the spatula 34 rotates along the center of the bottom end of the lower tube 14 in cooperation with the second clamping block 342 and the outer arc groove 311a, thereby smoothing the poured concrete;

[0063] S5. After pouring for a period of time, the hydraulic cylinder 4 is started again to drive the lower tube 14 to move up a certain distance. When the lower tube 14 rises, the insertion rod 121 will squeeze the gas in the gas cylinder 322, so that the gas passes through the first channel 321b and the second channel 321c to push the extension plate 323 out of the sliding cavity 321a to reduce the gap between the vibrating assembly 3 and the lower tube 14, thereby slowing down the concrete pouring speed;

[0064] S6. Then repeat the steps S2-S4 to pour the concrete layer by layer until it is completely poured.

[0065] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the specification and its equivalents.

8. A casting method for green building construction, using the casting device for green building construction according to claim 7, characterized in that: The following steps are involved: S1, feeding the mixed concrete aggregate into the casting tank (1), and starting the hydraulic cylinder (4) to extend the lower pipe (14) into the mold of the prefabricated structure close to the bottom; S2, then closing the hydraulic cylinder (4), and simultaneously starting the servo motor (21) to drive the auger (23) to rotate via the rotating shaft (22) to squeeze the concrete aggregate out along the corrugated pipe (13) and the lower pipe (14) and pour it into the mold; S3. During pouring, the rotating shaft (22) drives the clamping rod (332d) to rotate via the transmission rod (332). When the clamping rod (332d) rotates to the spiral groove of the inner groove (331b), it presses down the conductive cylinder (331) and squeezes the first spring (313). When the clamping rod (332d) rotates to the vertical groove, the restoring force of the first spring (313) pushes the conductive cylinder (331) upward, so that during the discharging process, the conductive cylinder (331) continuously drives the vibrating plate (333) to vibrate up and down, thereby reducing the gaps between the poured concrete. S4, when the conducting tube (331) vibrates up and down, the spatula (34) rotates along the center of the bottom end of the lower tube (14) in cooperation with the second clamping block (342) and the outer arc groove (311a), thereby smoothing the poured concrete; S5. After pouring for a period of time, the hydraulic cylinder (4) is started again to drive the lower tube (14) to move upward for a certain distance. When the lower tube (14) rises, the insertion rod (121) squeezes the gas in the gas cylinder (322), so that the gas passes through the first channel (321b) and the second channel (321c) to push the extension plate (323) out of the sliding cavity (321a) to reduce the gap between the vibrating assembly (3) and the lower tube (14), thereby slowing down the concrete pouring speed. S6. Then repeat the steps S2-S4 to pour the concrete layer by layer until it is completely poured.
