Description

Technical Field

[0001] This invention relates to the field of silo construction technology, specifically to a prestressed silo construction device and method. Background Technology

[0002] When constructing a prestressed silo, concrete is typically poured over the prestressed steel reinforcement frame. After the concrete has solidified, a slipform construction method is used to lift the inner and outer molds upwards, and then concrete pouring continues. During construction, because multiple connectors connect the inner and outer molds, and the prestressed steel reinforcement frame is also erected between them, the poured concrete tends to pile up and is difficult to level. Therefore, when pouring concrete, it can only be done manually, injecting the concrete sequentially through the gaps between the two connectors into the inner and outer molds. This operation is time-consuming and labor-intensive. Furthermore, as the silo rises, the danger of manual construction on the silo gradually increases. Summary of the Invention

[0032] Please see Figure 1-10 This invention provides a technical solution: a prestressed silo construction device and method, comprising an outer mold 1 and an inner mold 2, with an outer support platform 3 and an inner support platform 4 respectively fixedly connected to the outer mold 1 and the inner mold 2; a climbing mechanism is provided between the inner mold 2 and the outer mold 1, the climbing mechanism being used to drive the inner mold 2 and the outer mold 1 to climb upwards; a storage ring 5 is provided on the inner support platform 4, the storage ring 5 being used to temporarily store concrete; a sealing mechanism is provided on the inner support platform 4, the sealing mechanism being used to seal the concrete in the storage ring 5 within the storage ring 5; a material distribution mechanism is provided on the storage ring 5, the material distribution mechanism being used to evenly distribute the concrete in the storage ring 5 within the storage ring 5; a pushing mechanism is provided inside the storage ring 5, the pushing mechanism being used to push the evenly distributed concrete in the storage ring 5 to be evenly distributed between the outer mold 1 and the inner mold 2; a driving mechanism is provided on the inner mold 2, the driving mechanism being used to drive the pushing mechanism and the material distribution mechanism to operate;

[0033] like Figure 2-4 , Figure 6 As shown, during the construction of the prestressed silo, concrete is typically poured onto the prestressed steel reinforcement frame. After the concrete solidifies, a slipform construction method is used to lift the inner mold 2 and outer mold 1 upwards, and then concrete pouring continues. The inner mold 2 and outer mold 1 are positioned on both sides of the prestressed steel reinforcement frame, and then concrete is injected into the storage ring 5 using a concrete pump truck. When the concrete pump truck injects concrete, the drive mechanism is activated, which drives the uniform distribution mechanism. Since the concrete pump truck injects concrete into the storage ring 5 at a single point, the uniform distribution mechanism ensures that the concrete injected into the storage ring 5 is evenly distributed within it. When the amount of concrete stored in the storage ring 5 is high, the concrete pump is stopped. The vehicle's drive mechanism then drives the pushing mechanism, which quickly and evenly pushes the concrete in the storage ring 5 through the gap between the two connecting frames 7 to the inner mold 2 and the outer mold 1. This eliminates the need for manual operation, saving time and effort, and also ensures that the concrete is evenly distributed between the inner mold 2 and the outer mold 1. Since the concrete in the storage ring 5 is pushed to the inner mold 2 and the outer mold 1 in a short time, the concrete in the inner mold 2 and the outer mold 1 sets at similar times. After the concrete in the inner mold 2 and the outer mold 1 sets, the first climbing mechanism is activated to lift the inner mold 2 and the outer mold 1 a certain distance, and then the concrete pump truck is restarted to continue injecting concrete into the storage ring 5.

[0034] like Figure 6As shown, as a further embodiment of the present invention, the climbing mechanism includes a plurality of first climbing rods 6, which are arranged in a circumferential array between the inner mold 2 and the outer mold 1; a connecting frame 7 is sleeved on the first climbing rod 6, the connecting frame 7 is located above the inner mold 2 and the outer mold 1 and is fixedly connected to both the inner mold 2 and the outer mold 1; a first climbing component 8 is fixedly connected inside the connecting frame 7, and the first climbing component 8 is used to drive the connecting frame 7 to climb upward along the first climbing rod 6;

[0035] During operation, once the concrete between the inner mold 2 and the outer mold 1 has solidified, all the first climbing components 8 are activated simultaneously. The first climbing components 8 drive the connecting frame 7 connected to them to move upward along the first climbing rod 6. When all the connecting frames 7 move upward, they will drive the inner mold 2 and the outer mold 1 to move upward simultaneously.

[0036] like Figure 4-6 As shown, as a further embodiment of the present invention, the material leveling mechanism includes a first rotating drum 9, which is fixedly connected to the bottom part of the storage ring 5; the first rotating drum 9 is rotatably connected to the inner support platform 4; and a sealing cylinder 10 is rotatably connected to the inner side of the first rotating drum 9.

[0037] The sealing mechanism includes multiple sealing plates 11, the number of sealing plates 11 is equal to the number of connecting frames 7, and the multiple sealing plates 11 are arranged crosswise between the multiple connecting frames 7; the two ends of the sealing plate 11 are sealed and fitted to two adjacent connecting frames 7; a fixed rod 12 is fixedly connected between two adjacent connecting frames 7, and a sliding rod 13 is slidably connected on the fixed rod 12, and the bottom end of the sliding rod 13 is fixedly connected to the sealing plate 11.

[0038] During operation, when the concrete pump truck injects concrete into the storage ring 5, the first rotating drum 9 will rotate, which in turn will cause the storage ring 5 to rotate. Since the concrete pump truck injects concrete into the storage ring 5 at a single point, the concrete injected by the concrete pump truck can be evenly spread on the storage ring 5 as the storage ring 5 rotates. The concrete on the storage ring 5 will be kept on the storage ring 5 by the obstruction of the sealing cylinder 10 and the sealing plate 11.

[0039] like Figure 8-10 As shown, as a further embodiment of the present invention, the pushing mechanism includes a pushing plate 14, which is attached to the upper surface of the storage ring 5; the pushing plate 14 is in the shape of a spiral, with one inner end of the pushing plate 14 fixedly connected to the sealing cylinder 10 and the outer end attached to the sealing plate 11; the sealing cylinder 10 is provided with an opening and closing mechanism, which is used to drive all the sealing plates 11 to move upward and open when the sealing cylinder 10 rotates and drives the pushing plate 14 to push the material.

[0040] The opening and closing mechanism includes a second rotating cylinder 15, which is in contact with the inner wall of the sealing cylinder 10 and is slidably connected to the sealing cylinder 10; a drive ring 16 is fixedly connected to the second rotating cylinder 15, and the drive ring 16 is also in contact with all the sliding rods 13; a fixed frame 17 is fixedly connected to the bottom of the inner mold 2, and a third rotating cylinder 18 is rotatably connected to the fixed frame 17; the second rotating cylinder 15 and the third rotating cylinder 18 are slidably connected, and multiple springs 19 are provided between the second rotating cylinder 15 and the third rotating cylinder 18, with the upper and lower ends of the springs 19 fixedly connected to the second rotating cylinder 15 and the third rotating cylinder 18 respectively; a lifting mechanism is provided inside the second rotating cylinder 15, which is used to drive the second rotating cylinder 15 to move upward when rotating clockwise and to drive the second rotating cylinder 15 to reset when rotating counterclockwise;

[0041] The lifting mechanism includes a second climbing rod 20, on which a driving block 21 is sleeved. Multiple spiral grooves 22 are evenly distributed on the driving block 21 in a circular array. The spiral grooves 22 are in a clockwise spiral upward shape. Multiple fixing blocks 23 are evenly fixedly connected inside the second rotating drum 15. The number of fixing blocks 23 is equal to the number of spiral grooves 22, and the fixing blocks 23 are located at the bottom of the driving block 21. A second climbing assembly 24 is fixedly connected to the driving block 21, and the second climbing assembly 24 is used to drive the driving block 21 to climb upward along the second climbing rod 20.

[0042] During operation, when it is necessary to push all the concrete on the storage ring 5 between the inner mold 2 and the outer mold 1, the third rotating drum 18 is driven to rotate counterclockwise. The rotation of the third rotating drum 18 drives the second rotating drum 15 to rotate, which in turn drives the pusher plate 14 connected to it to rotate. The pusher plate 14, rotating counterclockwise, pushes the concrete on the storage ring 5 outwards. As the second rotating drum 15 rotates, it drives multiple fixed blocks 23 connected to it to rotate as well. Because the spring 19 always applies an upward force to the second rotating drum 15, when the fixed block 23 rotates to the spiral groove 22 on the drive block 21, the second rotating drum 15 directly drives the fixed block 23 into the spiral groove 22. As the second rotating drum 15 continues to rotate, the fixed block 23 moves upward along the spiral groove 22, driving the second rotating drum 15 upward. This upward movement of the second rotating drum 15 drives the drive ring 16 upward, which in turn... This will cause all the sliding rods 13 to move upward, and the sliding rods 13 will cause the sealing plate 11 connected to them to move upward. When the sealing plate 11 moves to the upper position, the pusher plate 14 can push the concrete through the two connecting frames 7 to the position between the inner mold 2 and the outer mold 1. After all the concrete on the storage ring 5 has been pushed between the inner mold 2 and the outer mold 1, the third rotating drum 18 and the storage ring 5 are driven to rotate clockwise. The third rotating drum 18 drives the second rotating drum 15 to rotate clockwise. At this time, the fixing block 23 on the second rotating drum 15 is located above the driving block 21. The spring 19 begins to apply a downward elastic force to the second rotating drum 15. Therefore, when the second rotating drum 15 drives the fixing block 23 to move to the position of the spiral groove 22 on the driving block 21, the fixing block 23 will directly enter the spiral groove 22 and move downward along the spiral groove 22. At this time, the second rotating drum 15 will drive the driving ring 16 to gradually move downward. When the driving ring 16 moves downward, the sealing plate 11 will automatically fall downward to continue to seal the storage ring 5.

[0043] like Figure 4 , Figure 9-10 As shown, as a further embodiment of the present invention, the drive mechanism includes a motor 25, which is fixedly connected to the fixed frame 17, and a first synchronous pulley 26 is fixedly connected to the bottom end of the output shaft of the motor 25; a second synchronous pulley 27 is rotatably connected to the middle position of the fixed frame 17, and the second synchronous pulley 27 is in clearance fit with the second climbing rod 20; a synchronous belt 28 is provided on the second synchronous pulley 27, and the synchronous belt 28 simultaneously meshes with the first synchronous pulley 26 and the second synchronous pulley 27; a conversion mechanism is provided on the second synchronous pulley 27, which is used to simultaneously drive the first rotating drum 9 and the third rotating drum 18 to rotate counterclockwise when the second synchronous pulley 27 rotates counterclockwise, and drive the third rotating drum 18 to rotate clockwise when the second synchronous pulley 27 rotates clockwise, while the first rotating drum 9 remains stationary;

[0044] The conversion mechanism includes a rotating disk 29, on which four arc-shaped grooves 30 are formed. The distances from the two ends of the arc-shaped grooves 30 to the center of the rotating disk 29 are different. The four arc-shaped grooves 30 are arranged in a circumferential array on the rotating disk 29. Four sliding rods 31 are slidably connected to the third rotating cylinder 18. One end of each of the four sliding rods 31 is slidably connected to one of the four arc-shaped grooves 30. All four sliding rods 31 pass through the third rotating cylinder 18, and a friction block 32 is fixedly connected to one end of each sliding rod 31. The friction block 32 is arc-shaped, and its diameter is equal to the inner diameter of the first rotating cylinder 9. A ratchet 33 is fixedly connected to the first rotating cylinder 9. Multiple pawls 34 are engaged on the ratchet 33, and all of the multiple pawls 34 are fixedly connected to the inner support platform 4.

[0045] During operation, when the starting motor 25 drives the first synchronous pulley 26 to rotate, the first synchronous pulley 26 drives the second synchronous pulley 27 to rotate via the synchronous belt 28. The rotation of the second synchronous pulley 27 drives the rotating disk 29 to rotate. When the rotating disk 29 rotates clockwise, it pushes all four sliding rods 31 to their outermost positions through the four arc-shaped grooves 30 on its surface. At this time, the friction blocks 32 on the sliding rods 31 are precisely in contact with the inner wall of the first rotating drum 9. As the rotating disk 29 rotates clockwise, the friction blocks 32 on the sliding rods 31 are in contact with the inner wall of the first rotating drum 9. The sliding rod 31 and friction block 32 drive the third rotating cylinder 18 and the first rotating cylinder 9 to rotate clockwise simultaneously. When the second synchronous wheel 27 drives the rotating disk 29 to rotate counterclockwise, the rotating disk 29 will pull the four sliding rods 31 to the innermost position through the four arc grooves 30 on its surface. At this time, the friction block 32 on the sliding rod 31 will disengage from the inner wall of the first rotating cylinder 9. Therefore, when the rotating disk 29 rotates counterclockwise, it will drive the third rotating cylinder 18 to rotate counterclockwise, while the first rotating cylinder 9 will remain stationary under the action of the ratchet 33 and pawl 34.

[0046] like Figure 1 As shown, as a further aspect of the present invention, a prestressed silo construction method comprises the following specific steps:

[0047] Step 1: Set up the inner mold 2 and the outer mold 1, and then start the concrete pump truck to inject concrete into the storage ring 5;

[0048] Step 2: Start the drive mechanism, which drives the material distribution mechanism to run, and the material distribution mechanism makes the concrete evenly distributed on the storage ring 5.

[0049] Step 3: The drive mechanism starts the pushing mechanism, which opens the sealing mechanism and quickly pushes all the concrete on the storage ring 5 between the inner mold 2 and the outer mold 1. The concrete is evenly distributed between the inner mold 2 and the outer mold 1.

The friction block (32) is arc-shaped and its diameter is equal to the inner diameter of the first rotating cylinder (9). A ratchet (33) is fixedly connected to the first rotating cylinder (9). Multiple pawls (34) are engaged on the ratchet (33). All of the multiple pawls (34) are fixedly connected to the inner support platform (4).

6. A prestressed silo construction method, applicable to the prestressed silo construction device described in any one of claims 1-5, characterized in that: The specific steps of this method are as follows: Step 1: Set up the inner mold (2) and the outer mold (1), and then start the concrete pump truck to inject concrete into the storage ring (5); Step 2: Start the drive mechanism, which drives the material distribution mechanism to run. The material distribution mechanism makes the concrete evenly distributed on the storage ring (5). Step 3: The drive mechanism starts the material pushing mechanism. The material pushing mechanism opens the sealing mechanism and quickly pushes all the concrete on the storage ring (5) between the inner mold (2) and the outer mold (1). The concrete is evenly distributed between the inner mold (2) and the outer mold (1).
