Description

Technical Field

[0001] This application relates to the field of concrete pouring technology and equipment, and in particular to a high-density reinforced concrete diversion and pouring equipment for beams and columns. Background Technology

[0002] Concrete pouring is a core process in building construction. Concrete from a concrete mixer truck is transported to the high-altitude work surface, then poured into the formwork to bond with the reinforcing steel in beams and columns. During construction, it is crucial to control the pouring rate and layer thickness, ensure proper vibration compaction, and prevent quality issues such as segregation and honeycombing. Simultaneously, curing measures must be implemented to guarantee concrete strength suitable for the load-bearing requirements of high-rise structures. In low-rise building construction, boom-type concrete pump trucks are typically used to pump concrete to the work surface. However, as building height increases, the work surface may exceed the operating range of boom-type concrete pump trucks. In such cases, a trailer-mounted concrete pump connected to a pump pipe is required to transport concrete.

[0003] In high-rise building concrete pouring operations, a placing boom is typically connected to the end of the pump pipe. The placing boom, via its boom, precisely delivers pumped concrete to the pouring surface. It can rotate 360 ​​degrees, providing wide coverage, significantly improving efficiency, reducing manpower, and ensuring pouring quality and construction safety. Concrete is transported from the factory to the construction site by concrete mixer trucks. Once a concrete mixer truck runs out of concrete, it needs to leave the trailer-mounted concrete pump as soon as possible, while a new concrete mixer truck continues to supply concrete to the trailer-mounted concrete pump.

[0004] Regarding the aforementioned technologies, concrete mixer trucks in the factory need to be filled and dispatched sequentially according to the pouring progress. Due to road conditions, it is easy for a situation to occur where the concrete in one concrete mixer truck runs out before the next concrete mixer truck arrives, causing the concrete pouring operation to be interrupted and affecting the construction quality. Summary of the Invention

[0005] To prevent interruption of concrete pouring operations, this application provides a high-density reinforced concrete beam and column diversion and pouring device.

[0006] This application provides a high-density reinforced concrete beam and column diversion and pouring device, which adopts the following technical solution: A high-density reinforced concrete beam and column diversion and pouring equipment includes a support frame, a storage tank for buffering concrete from a pump pipe is rotatably connected to the top of the support frame, a discharge port is provided on the storage tank, a conveying mechanism for conveying concrete to the discharge port is provided inside the storage tank, and a diversion trough for guiding concrete from the discharge port to the pouring position is connected to the storage tank.

[0007] By adopting the above technical solution, during concrete pouring operations, the concrete mixer truck transfers concrete to the inlet of the trailer-mounted concrete pump. The trailer-mounted concrete pump then pumps the concrete through a pump pipe to a storage tank for buffering. A conveying mechanism then transports the concrete from the storage tank to the outlet and pours it through a guide chute. The storage tank allows for continued pouring operations even after the concrete in the mixer truck is depleted, using the buffered concrete until the next mixer truck arrives and resumes supply. This helps prevent interruptions in concrete pouring operations and ensures the quality of construction.

[0008] Optionally, the conveying mechanism includes a rotary motor, which is fixedly connected to the storage tank. The output shaft of the rotary motor extends into the storage tank, and a spiral blade is coaxially fixedly connected to the output shaft of the rotary motor.

[0009] By adopting the above technical solution, the rotary motor drives the spiral blades to rotate, and the rotating spiral blades continuously lift the concrete in the storage tank, raising the concrete to the discharge port position.

[0010] Optionally, the spiral blade is provided with a return port for concrete to pass through, and the return port is located near the central axis of the spiral blade.

[0011] By adopting the above technical solution, during concrete pouring operations, after the completion of one structure, it is necessary to pause the pouring operation, adjust the direction or position of the pouring equipment, and then continue pouring the next structure. At this time, the concrete in the storage tank is at risk of solidification. In this application, a return port is opened on the spiral blades. When the pouring operation stops, the rotating motor reverses, and the spiral blades reverse to transport the concrete away from the discharge port until the concrete is squeezed against the inner wall of the storage tank, causing the concrete to return from the return port, achieving a mixing effect and preventing the concrete from solidifying.

[0012] Optionally, the output shaft of the rotary motor is coaxially fixedly connected to a drive sprocket, and a driven sprocket is rotatably connected to the storage tank. A transmission chain for transmission is provided between the drive sprocket and the driven sprocket. A vibrating wheel is coaxially fixedly connected to the driven sprocket, and multiple vibrating springs for striking the guide groove are fixedly connected to the vibrating wheel. The vibrating springs are evenly distributed along the circumference of the vibrating wheel.

[0013] By adopting the above technical solution, when the output shaft of the rotary motor rotates, it drives the drive sprocket to rotate, which in turn drives the driven sprocket and the vibrating wheel to rotate synchronously via the transmission chain. The vibrating spring periodically strikes the guide channel along the rotation of the vibrating wheel, causing the guide channel to vibrate and causing the concrete adhering to the channel wall to fall off, further suppressing the phenomena of material caking and initial setting, and improving the uniformity of returned material and the anti-caking effect.

[0014] Optionally, the guide channel is slidably connected to an expansion groove, the sliding direction of which is the same as the flow direction of the concrete in the guide channel.

[0015] By adopting the above technical solution and setting up an expansion groove with an adjustable sliding stroke, it can be adapted to the pouring points of beams and columns of different heights. At the same time, it can be used in conjunction with the diversion groove to adjust the length of the overall concrete diversion path, thereby enhancing the adaptability of the diversion pouring equipment in various construction environments.

[0016] Optionally, the telescopic groove includes a slider and a groove body, with the slider slidably connected to the guide groove and the groove body hinged to the slider.

[0017] By adopting the above technical solution, the trough is hinged to the slider, and the angle between the guide trough and the telescopic trough can be changed by rotating the telescopic trough, which further improves the flexibility of the telescopic trough to adapt to pouring points of different heights and positions.

[0018] In summary, this application includes at least one of the following beneficial technical effects: When concrete pouring is being carried out at the construction site, after the concrete mixer truck arrives, the vehicle position is adjusted to transfer the concrete to the feed inlet of the trailer concrete pump. The trailer concrete pump then pumps the concrete through the pump pipe to the storage tank to buffer the concrete. The conveying mechanism then transports the concrete from the storage tank to the discharge port and pours it through the guide channel. After the concrete in the concrete mixer truck is exhausted, the concrete buffered in the storage tank can be used to continue the pouring operation, filling the gap in the supply time between two adjacent concrete mixer trucks. This helps to prevent the concrete pouring operation from being interrupted and ensures the quality of the building construction. During concrete pouring operations, once a point is poured, the pouring operation needs to be temporarily stopped. After adjusting the direction or position of the pouring equipment, the equipment is aligned with the next pouring point to continue pouring. At this time, the concrete in the storage tank stops moving and there is a risk of solidification. In this application, a return port is opened on the spiral blade. When the pouring operation stops, the rotating motor reverses, and the spiral blade reverses to transport the concrete away from the discharge port until the concrete is squeezed against the inner wall of the storage tank, causing the concrete to return from the return port, thereby achieving the effect of continuous mixing of concrete and preventing the concrete from solidifying. During concrete pouring, the rotary motor operates, and its output shaft rotates, driving the drive sprocket to rotate in the same direction. This, in turn, drives the driven sprocket and vibrating wheel to rotate synchronously via the transmission chain. The vibrating spring periodically strikes the guide channel along with the rotation of the vibrating wheel, causing the guide channel to vibrate and causing the concrete adhering to the channel wall to fall off. This further inhibits the phenomena of material caking and initial setting, and improves the uniformity of returned material and the anti-caking effect. Attached Figure Description

Detailed Implementation

[0024] The present application will be further described in detail below with reference to all the accompanying drawings.

[0025] This application discloses a high-density reinforced concrete beam and column diversion and pouring equipment.

[0026] Reference Figure 1 and Figure 2 A high-density reinforced concrete beam and column diversion and pouring device is disclosed, suitable for concrete pouring operations of high-density reinforced concrete beams and columns in high-rise buildings. It effectively buffers concrete, prevents interruption of pouring operations, and features anti-concrete solidification and adaptability to multiple pouring points. The device includes a support frame 1, made of metal, used to construct and fix the entire concrete diversion and pouring device. During pouring operations, it is directly fixed to the building formwork. A storage tank 2 is rotatably connected to the top of the support frame 1, and a pump pipe is connected to the center of the bottom of the storage tank 2. During concrete pouring operations, a concrete mixer truck aligns its rear end with the inlet of a trailer-mounted concrete pump and transfers the concrete into the pump. The trailer-mounted pump then pumps the concrete through the pump pipe into the storage tank 2, where the concrete is buffered. The storage tank 2 has a discharge port 21, and a conveying mechanism 3 is installed inside the storage tank 2 to transport concrete to the discharge port 21. A guide channel 4 is connected to the storage tank 2, allowing concrete overflowing from the discharge port 21 to flow to the pouring location via the guide channel 4. When the concrete in the concrete mixer truck is depleted, the trailer-mounted concrete pump temporarily stops supplying concrete to the storage tank 2. At this time, the concrete buffered in the storage tank 2 can continue to be used for pouring operations until the next concrete mixer truck arrives and resumes supplying concrete. This helps prevent interruptions in concrete pouring operations and ensures the quality of construction.

[0027] Reference Figure 1 and Figure 2 The conveying mechanism 3 includes a rotary motor 31, which is mounted and fixed on the storage tank 2. The output shaft of the rotary motor 31 is inclined and coaxial with the storage tank 2. The output shaft of the rotary motor 31 extends into the storage tank 2, and a spiral blade 32 is coaxially welded to the outside of the output shaft of the rotary motor 31. The edge of the spiral blade 32 is in contact with the inner wall of the storage tank 2. When the concrete is poured, the rotary motor 31 drives the spiral blade 32 to rotate. The rotating spiral blade 32 continuously lifts the concrete at the bottom of the storage tank 2 to the discharge port 21, thus completing the discharge of the concrete from the storage tank 2.

[0028] Reference Figure 1 and Figure 2 During concrete pouring operations, once one structure is completed, the pouring operation needs to be paused, and the direction or position of the pouring equipment adjusted to align the guide trough 4 with the next pouring point before continuing the pouring of the next structure. At this time, the concrete in the storage tank 2 stops moving, posing a risk of solidification. In this application, the spiral blade 32 has a return port 321, a rectangular through-hole located near its central axis, allowing concrete to pass freely through. During the pause in pouring operations, the output shaft of the rotary motor 31 can be reversed, conveying the concrete away from the outlet 21. This pushes the concrete against the inner wall of the storage tank 2, causing it to flow back through the return port 321, thus mixing the concrete in the storage tank 2, preventing solidification, and ensuring the quality of construction.

[0029] Reference Figure 1 and Figure 3After the concrete overflows from the discharge port 21 into the guide channel 4, it flows to the pouring position by its own weight and fluidity. However, the concrete itself has a certain viscosity and the flow rate is low, which is not conducive to further improving the pouring efficiency. In this embodiment, the output shaft of the rotary motor 31 is coaxially fixedly connected to a drive sprocket 311. The drive sprocket 311 is set outside the storage tank 2. A driven sprocket 22 is rotatably connected to the storage tank 2. A transmission chain 5 is sleeved between the drive sprocket 311 and the driven sprocket 22. A vibrating wheel 221 is coaxially fixedly connected to the end of the driven sprocket 22 away from the storage tank 2. A plurality of vibration springs 2211 are uniformly welded circumferentially on the outer peripheral wall of the vibration wheel 221. The free end of the vibration spring 2211 is set towards the guide channel 4, and the length of the vibration spring 2211 is adapted so that it can periodically strike the outer wall of the guide channel 4 when it rotates with the vibration wheel 221. During the pouring operation, the output shaft of the rotary motor 31 rotates, driving the drive sprocket 311 to rotate. Through the transmission chain 5, the driven sprocket 22 and the vibrating wheel 221 rotate synchronously. The vibrating spring 2211 periodically strikes the guide channel 4 along the rotation of the vibrating wheel 221. The guide channel 4 vibrates accordingly, causing the concrete adhering to the channel wall to fall off and increasing the flow speed of the concrete along the slope direction of the guide channel 4. This further suppresses the phenomena of material hardening and initial setting, and improves the pouring efficiency.

[0030] Reference Figure 1 and Figure 4 By rotating the storage tank 2, the release direction of the concrete can be adjusted, thereby adjusting the concrete pouring position. However, some structures requiring pouring have different designs, and to meet construction quality requirements, the pouring height needs to be adjusted. In this embodiment, a telescopic groove 41 is slidably connected to the guide channel 4. The sliding direction of the telescopic groove 41 is the same as the flow direction of the concrete within the guide channel 4. The sliding stroke of the telescopic groove 41 is adjustable, thus adapting to pouring points of beams and columns of different heights. Simultaneously, it can work with the guide channel 4 to adjust the overall length of the concrete guide path, enhancing the adaptability of the guide pouring equipment in various construction environments.

[0031] Reference Figure 1 and Figure 4 The expansion groove 41 includes a slider 411 and a groove body 412. The slider 411 is slidably connected to the guide groove 4, and the groove body 412 is hinged to the slider 411. The angle between the guide groove 4 and the expansion groove 41 can be changed by rotating the expansion groove 41, thereby adjusting the guide angle and further improving the flexibility of the expansion groove 41 to adapt to pouring points of different heights and positions.

[0032] The implementation principle of the high-density reinforced concrete beam and column pouring equipment in this application embodiment is as follows: When pouring high-density reinforced concrete beams and columns for high-rise buildings, a concrete mixer truck transports concrete from a nearby factory to the construction site and aligns it with the feed position of a trailer-mounted concrete pump, supplying concrete to the trailer-mounted concrete pump. The trailer-mounted concrete pump then pumps the concrete through a pump pipe into the storage tank 2 of this equipment for buffering. When the concrete in the storage tank 2 has reached a certain amount, the rotary motor 31 is started, driving the spiral blades 32 to rotate forward. The spiral lift force raises the concrete in the storage tank 2 to the discharge port 21 for discharge. The concrete is then guided through the guide channel 4 and the expansion channel 41 to the beam and column pouring position. At the same time, the vibrating wheel 221 continues to rotate with the rotary motor 31, causing the vibrating spring 2211 to strike the guide channel 4, completing the pouring operation. When a concrete mixer truck runs out of concrete, the concrete buffered in storage tank 2 can continue to supply material for the pouring operation until the next concrete mixer truck arrives to replenish the material, thus avoiding interruption of the pouring operation. When it is necessary to change the pouring point and suspend the pouring, the rotary motor 31 reverses, driving the spiral blades 32 to reverse and mix the concrete in storage tank 2. According to the height and horizontal distance of the new pouring point, the sliding slider 411 adjusts the extension length of the telescopic groove 41, and the groove body 412 is rotated to adjust the guide angle. After adapting to the new pouring point, the rotary motor 31 is restarted to continue the pouring operation.

[0033] 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.
