Description

Technical Field

[0001] This invention relates to the technical field of concrete pouring equipment, and in particular to a concrete pouring system for sealing silos. Background Technology

[0002] Silos are commonly used for grain storage. The hollow interior of a silo stores grain, while a funnel at the bottom allows grain to be discharged. There are no internal support columns; the silo roof is supported by its side walls. A grain inlet is located in the center of the roof. Grain is transported to the inlet by a conveyor and then falls into the silo for storage before being discharged through the funnel. When sealing a conical-top silo, since there are no internal support columns, a pouring platform is erected using the silo's side walls as support. The roof is then poured using this platform as support. During pouring, the designed grain inlet area is left unpoured. Concrete is then poured gradually outwards from the designed grain inlet, finally completing the roof. However, uneven distribution of the poured concrete during this process can cause the pouring platform to tilt, affecting the roof's construction quality and increasing the risk of platform collapse. Summary of the Invention

[0003] To reduce the probability of the pouring platform tilting, this application provides a concrete pouring system for silo capping.

[0004] The concrete pouring system for sealing silos provided in this application adopts the following technical solution: A concrete pouring system for sealing a silo includes a feeding device and a distribution device. The feeding device is connected to the distribution device and pumps concrete into the distribution device. The distribution device includes a distribution cylinder and a driving component. The distribution cylinder is rotatably mounted in the middle of a pouring platform. The driving component drives and connects to the distribution cylinder and is mounted on the pouring platform. The distribution cylinder is connected to a pressure regulator for changing the air pressure inside the distribution cylinder. The distribution cylinder is rotatably connected to a feeding pipe that communicates with the distribution cylinder. One end of the feeding pipe is connected to the feeding device. Multiple grout delivery pipes are installed circumferentially on the distribution cylinder.

[0005] By adopting the above technical solution, during the pouring process, the air pressure inside the distribution cylinder is increased, and the concrete inside the distribution cylinder is forced into the grouting pipes by the air pressure. The flow rate in each grouting pipe is basically the same, thus maintaining a basically the same amount of concrete discharged from each grouting pipe. Each grouting pipe is arranged along the circumference of the distribution cylinder, and the driving component drives the distribution cylinder to rotate. The distribution cylinder drives the grouting pipes to rotate, ensuring that the amount of concrete poured in all directions from the distribution cylinder as the center remains basically balanced. This keeps the center of gravity of the pouring platform basically unchanged, reduces the probability of the pouring platform tilting, reduces the risk of the pouring platform collapsing, and improves the construction quality of the sump roof.

[0006] Preferably, the axis of the distribution cylinder coincides with the center of gravity axis of the pouring platform, and the multiple grout delivery pipes are evenly distributed along the circumference of the distribution cylinder.

[0007] By adopting the above technical solution, no matter how much concrete the feeding device feeds into the distribution cylinder, it will not affect the center of gravity of the pouring platform. The amount of concrete entering each grouting pipe from the distribution cylinder is basically equal, so the concrete output from the grouting pipe will not affect the center of gravity of the pouring platform, thus keeping the center of gravity of the pouring platform unchanged during the pouring process.

[0008] Preferably, a suspension rod is provided on one side of the grout delivery pipe, one end of the suspension rod is connected to the distribution cylinder, and a plurality of slip rings are slidably installed on the suspension rod and distributed along the axial direction of the suspension rod. The grout delivery pipe is connected to the slip rings and is bendable.

[0009] By adopting the above technical solution, the suspension rod and slip ring suspend the grout delivery pipe in the air, and allow the end of the grout delivery pipe away from the distribution cylinder to move to any position along the radial direction of the distribution cylinder. This allows the grout to be poured gradually from the distribution cylinder as the center, while avoiding the grout delivery pipe from moving on the surface of the poured concrete and causing unevenness on the surface of the sump.

[0010] Preferably, the lower end of the feed pipe passes through the distribution cylinder and is fixedly connected to the pouring platform. The upper end of the feed pipe is fitted with a cable sleeve, and the cable sleeve is connected to a cable. The end of the cable away from the cable sleeve is connected to the end of the suspension rod away from the distribution cylinder. The lower end of the feed pipe is sealed, and the feed pipe is provided with a feed hole on the side wall inside the distribution cylinder.

[0011] By adopting the above technical solution, since the end of the suspension rod away from the distribution cylinder is unsupported, the concrete flowing in the grouting pipe during the pouring process has a large weight, which may cause the suspension rod to break. However, by connecting the pouring platform through the supply pipe, with a cable sleeve over the supply pipe, and then using a cable to connect the supply pipe and the suspension rod, an upward tension is provided to the end of the suspension rod away from the distribution cylinder, without affecting the rotation of the suspension rod, thereby maintaining the stable support of the suspension rod.

[0012] Preferably, the distance between the suspension rod and the designed warehouse roof is not less than 2m.

[0013] By adopting the above technical solution, if the suspension rod and grout delivery pipe are too low, they may hit workers during rotation, which could cause safety accidents. However, workers are less likely to be more than 2 meters away, which can reduce the probability of the suspension rod and grout delivery pipe hitting workers.

[0014] Preferably, a pipe joint is fixedly fitted at one end of the feeding pipe extending outside the distribution cylinder, and a clamp is fitted over the pipe joint. The pipe joint is connected to the feeding device and fixed by the clamp.

[0015] By adopting the above technical solution, when connecting the feeding device, one end of the sleeve can be directly sleeved over the discharge pipe of the feeding device, and then a clamp can be used to fix it, which is convenient and quick.

[0016] Preferably, the end of the grout delivery pipe away from the distribution cylinder is connected to a casting pipe, which is a telescopic pipe.

[0017] By adopting the above technical solution, since the top of the silo is conical and the height of different positions from the center of the distribution cylinder is different, the required length of the pouring pipe is also different. The pouring pipe is a telescopic pipe, which is easy to adjust the length to meet the pouring requirements of different positions.

[0018] Preferably, a pouring valve is installed inside one end of the slurry delivery pipe connected to the distribution cylinder, and a feed valve is installed inside the feeding pipe.

[0019] By adopting the above technical solution, since the concrete supplied by the feeding device enters the cylinder from the upper end of the feeding pipe, and the feeding pipe is used to connect the cables and needs to be set at a relatively high height, the concrete falls from a relatively high height from the feeding pipe. The concrete in the feeding pipe in the distribution cylinder experiences greater pressure, allowing it to enter the distribution cylinder from the feeding pipe. When the feeding device stops supplying material, due to the air pressure in the distribution cylinder, the concrete in the feeding pipe will remain stationary after falling to a certain height. At this time, the pouring valve is closed, and the distribution cylinder is evacuated through the air pressure regulator, creating negative pressure inside the distribution cylinder and drawing the concrete from the feeding pipe into the distribution cylinder. Then, the feed valve is closed, and air is supplied to the distribution cylinder through the air pressure regulator, increasing the air pressure inside the distribution cylinder. The pouring valve is then opened, and the concrete in the distribution cylinder is discharged into the grouting pipe, and then poured to the corresponding position through the grouting pipe, improving the utilization rate of concrete and reducing concrete waste.

[0020] In summary, this application includes at least the following beneficial technical effects: During the pouring process, the air pressure inside the distribution cylinder is increased, and the concrete inside the distribution cylinder is forced into the grouting pipes by the air pressure. The flow rate in each grouting pipe is basically the same, thereby maintaining the amount of concrete discharged from each grouting pipe is basically the same. Moreover, each grouting pipe is arranged along the circumference of the distribution cylinder, and the driving component drives the distribution cylinder to rotate. The distribution cylinder drives the grouting pipes to rotate, ensuring that the amount of concrete poured in all directions around the distribution cylinder remains basically balanced. This keeps the center of gravity of the pouring platform basically unchanged, reduces the probability of the pouring platform tilting, reduces the risk of the pouring platform collapsing, and improves the construction quality of the sump roof.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a concrete pouring system for sealing the top of a silo.

[0027] Reference Figure 1 and Figure 2 A concrete pouring system for sealing a silo includes a feeding device 1 and a distribution device 2. The feeding device 1 is a concrete pump truck. The distribution device 2 is installed in the middle of a pouring platform 3 built on top of the silo. The discharge pipe of the feeding device 1 is connected to the distribution device 2, and the feeding device 1 pumps concrete from the ground into the distribution device 2. The distribution device 2 includes a distribution cylinder 201, a drive component 202, a feeding pipe 203, and a pressure regulator 204. The distribution cylinder 201 is installed on the pouring platform 3. One end of the feeding pipe 203 is connected to the distribution cylinder 201, and the other end is connected to the feeding device 1. The concrete from the feeding device 1 enters the distribution cylinder 201 through the feeding pipe 203. The drive component 202 is used to drive the distribution cylinder 201 to rotate. The drive component 202 is connected to the distribution cylinder 201 and drives the distribution cylinder 201 to rotate. The air pressure regulator 204 is an air pump. The air pressure regulator 204 is installed at the upper end of the distribution cylinder 201. The air pressure regulator 204 is connected to the distribution cylinder 201 and controls the air pressure inside the distribution cylinder 201.

[0028] Reference Figure 2 and Figure 3The upper and lower ends of the distribution cylinder 201 are closed. The distribution cylinder 201 is rotatably mounted in the middle of the pouring platform 3 via bearings. The upper end of the distribution cylinder 201 extends out from the reserved grain inlet. The distribution cylinder 201 is vertically arranged, and its axis coincides with the center of gravity axis of the pouring platform 3, thereby reducing the impact of changes in the amount of concrete in the distribution cylinder 201 on the center of gravity shift of the pouring platform 3. Multiple grout delivery pipes 205 are installed circumferentially on the distribution cylinder 201. One end of each grout delivery pipe 205 connects to the inner cavity of the distribution cylinder 201 and extends to the bottom of the inner cavity. The multiple grout delivery pipes 205 are evenly distributed circumferentially on the distribution cylinder 201. In this embodiment, four grout delivery pipes 205 are provided. The end of each grout delivery pipe 205 away from the distribution cylinder 201 is connected to a pouring pipe 210, which is a telescopic pipe. Each slurry delivery pipe 205 is connected to a suspension rod 206 at its top. Multiple suspension rods 206 are symmetrically arranged and horizontally positioned. The axial direction of the suspension rod 206 is the same as the radial direction of the distribution cylinder 201. One end of the suspension rod 206 is fixedly connected to the distribution cylinder 201, and the other end extends towards the side wall of the silo and is suspended in the air. The distance between the suspension rod 206 and the designed silo top is not less than 2m. In this embodiment, the distance between the suspension rod 206 and the upper end of the grain inlet is 3m. Multiple slip rings 207 are slidably mounted on the suspension rod 206. The slip rings 207 are sleeved on the outside of the suspension rod 206 and are distributed along the axial direction of the suspension rod 206. The grout delivery pipe 205 is fixedly connected to the slip rings 207. The grout delivery pipe 205 is made of flexible hose and is bendable. Suspending the grout delivery pipe 205 high in the air via the suspension rod 206 prevents it from colliding with materials and workers on the pouring platform 3 during rotation, improving construction safety. It also prevents the grout delivery pipe 205 from being dragged onto uncured concrete, reducing the possibility of damage to the poured concrete layer. Furthermore, suspending the grout delivery pipe 205 high in the air facilitates worker operation; a single worker can move both the grout delivery pipe 205 and the pouring pipe 210 to any desired location.

[0029] Reference Figure 2 and Figure 3The feed pipe 203 is vertically installed and passes through the distribution cylinder 201. Both ends of the distribution cylinder 201 are rotatably connected to the feed pipe 203, forming a seal. The axis of the feed pipe 203 coincides with the axis of the distribution cylinder 201. The lower end of the feed pipe 203 is sealed. A feed hole 215 is provided on the side wall of the feed pipe 203 inside the distribution cylinder 201. A sealing plate 216 is installed inside the feed pipe 203 below the feed hole 215. The upper surface of the sealing plate 216 is flush with the lower part of the feed hole 215 to prevent concrete residue from remaining in the feed pipe 203 below the feed hole 215. The lower end of the feed pipe 203 is fixedly connected to the pouring platform 3, and the upper end of the feed pipe 203 is connected to the discharge pipe of the feed device 1 through a pipe joint 211. The pipe connector 211 includes a rubber tube made of elastic rubber. The lower end of the pipe connector 211 is fitted over the feed pipe 203 and clamped and fixed by the clamp 212. The upper end of the pipe connector 211 is fitted over the discharge pipe of the feed device 1 and clamped and fixed by the clamp 212, thereby sealing the feed pipe 203 and the discharge pipe of the feed device 1. The feed device 1 discharges concrete from the discharge pipe. The concrete enters the feed pipe 203 from the upper end through the pipe connector 211, filling the feed pipe 203 and entering the distribution cylinder 201 through the feed hole 215. The distribution cylinder 201 then distributes the concrete evenly to each grout delivery pipe 205. The upper end of the feed pipe 203 is fitted with a cable sleeve 208, which is rotatably connected to the feed pipe 203. The cable sleeve 208 has multiple lifting lugs along its circumference, each corresponding to one of the suspension rods 206. A cable 209 is provided between the lifting lug and the end of the suspension rod 206 furthest from the distribution cylinder 201. One end of the cable 209 is tied to the end of the suspension rod 206 furthest from the distribution cylinder 201, and the other end is tied to the lifting lug. The cable 209 provides an upward tension to the suspended end of the suspension rod 206, thereby improving the stability of the suspension rod 206.

[0030] Reference Figure 2 and Figure 3 The driving component 202 is a motor, which is fixed on the pouring platform 3. The shaft of the driving component 202 is fixedly connected to a main gear, and the lower end of the distribution cylinder 201 is fixedly connected to a driven gear. The axis of the driven gear coincides with the axis of the distribution cylinder 201. The driven gear is sleeved on the outside of the feeding pipe 203 and rotatably connected to the feeding pipe 203. The main gear and the driven gear mesh with each other, and the driving component 202 drives the distribution cylinder 201 to rotate through the main gear and the driven gear.

[0031] Reference Figure 3A pouring valve 213 is installed inside one end of the grout delivery pipe 205 connected to the distribution cylinder 201, and a feed valve 214 is installed inside the supply pipe 203, located above the supply hole 215. When the supply device 1 normally injects concrete into the supply pipe 203, it controls both the pouring valve 213 and the feed valve 214 to open, and the air pressure regulator 204 inflates the distribution cylinder 201, raising the air pressure inside the distribution cylinder 201 to the set value, thus forcing the concrete inside the distribution cylinder 201 into the grout delivery pipe 205. When the feeding device 1 stops injecting concrete into the feeding pipe 203 for a set time, the pouring valve 213 is closed, the feed valve 214 is opened, and the air pressure regulator 204 evacuates air from the distribution cylinder 201 to create a certain vacuum. The concrete in the feeding pipe 203 is then drawn into the distribution cylinder 201. After the vacuum in the distribution cylinder 201 is maintained for a set time, the feed valve 214 is closed, the pouring valve 213 is opened, and the air pressure regulator 204 inflates the distribution cylinder 201 to raise the air pressure to the set value. The remaining concrete in the distribution cylinder 201 is then discharged into the grouting pipe 205 and poured into the corresponding position through the grouting pipe 205. After all the concrete in the distribution cylinder 201 is discharged, clean water is injected into the supply pipe 203 through the supply device 1 to clean the supply pipe 203, distribution cylinder 201 and grout delivery pipe 205, so as to avoid concrete residue from clogging the supply pipe 203, distribution cylinder 201 and grout delivery pipe 205.

[0032] It should be noted that during the pouring process, the position of the discharge pipe of the feeding device 1 in this embodiment remains stationary. Therefore, there is no need to control the position of the discharge pipe of the feeding device 1, simplifying the operation requirements of the feeding device 1 and making it easier for workers to operate. In contrast, when concrete is pumped to the top of the slab for pouring using a conventional concrete pump truck, a dedicated worker is required to operate the discharge pipe of the concrete pump truck to move the concrete to different pouring positions. Moreover, the concrete pouring system of this application can evenly distribute concrete to multiple positions, allowing multiple positions to be poured simultaneously, thus improving pouring efficiency. By controlling the power of the drive component 202, the rotation efficiency of the distribution cylinder 201 can be controlled, adapting to the needs of different pouring speeds. In addition, by controlling the air pressure in the distribution cylinder 201 by controlling the air pressure regulator 204, the flow rate of concrete in each grouting pipe 205 can be controlled simultaneously.

[0033] The implementation principle of a concrete pouring system for silo capping according to an embodiment of this application is as follows: the feeding device pumps concrete from the ground to the feeding pipe 203, and then enters the distribution cylinder 201 through the feeding pipe 203. The air pressure regulator 204 maintains a set air pressure in the distribution cylinder 201, which forces the concrete in the distribution cylinder 201 into the grouting pipe 205. The flow rate difference in each grouting pipe 205 is small, thereby maintaining the difference in the amount of concrete discharged from each grouting pipe 205, reducing the difference in the amount of concrete poured in each direction around the grain inlet, maintaining the stability of the center of gravity of the pouring platform 3, and reducing the probability of the pouring platform 3 tilting. In addition, the driving component 202 drives the distribution cylinder 201 to rotate, and the distribution cylinder 201 drives the grout delivery pipe 205 to rotate, so that each grout delivery pipe 205 rotates around the axis of the distribution cylinder 201, further balancing the amount of concrete poured in all directions around the grain inlet, thereby reducing the difference in the amount of concrete poured in all directions around the distribution cylinder 201, thus maintaining the stability of the center of gravity of the pouring platform 3, reducing the probability of the pouring platform 3 tilting, reducing the risk of the pouring platform 3 collapsing, and improving the construction quality of the silo roof.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
