Description

Technical Field

[0001] This utility model specifically relates to a flow guiding mechanism for concrete pouring, belonging to the field of building technology. Background Technology

[0002] Concrete guide pipes play a crucial role in the pouring process, primarily ensuring that concrete fully fills the mold and preventing air bubbles and segregation. They typically employ a sealed structure to prevent leakage and utilize bundled chutes to reduce the concrete's drop height, effectively avoiding segregation. For example, a 360° rotating elbow at the bottom of the branch chute, combined with a wooden chute, allows for flexible material distribution and reduces concrete impact. The guide pipes ensure that concrete densely fills every corner of the mold, preventing voids and facilitating the removal of air bubbles generated during filling. This significantly improves the concrete's density, strength, and overall quality.

[0003] Patent document CN221119239U discloses a flow guiding device for concrete pouring, "including a chute for conveying concrete and a base supporting the chute. The upper end of the base is provided with a support cylinder, and a telescopic rod is inserted into the upper end of the support cylinder. The lower end of the chute is connected to a rotating rod, which is connected to the telescopic rod via a connecting sleeve. The rotating rod and the connecting sleeve are rotatably engaged. A locking mechanism that engages with the connecting sleeve is provided on the side wall of the rotating rod. The locking mechanism enables the adjustment and fixing of the chute angle, thus avoiding the tedious manual handling and adjustment. This not only saves manpower but also prevents concrete from sticking to clothing during handling. It is convenient to adjust, easy to use, time-saving, labor-saving, and improves work efficiency."

[0004] However, the aforementioned published literature on a flow guiding device for concrete pouring mainly considers the angle adjustment of the concrete flow guiding pipe and avoids the handling problem. It does not take into account the problem of concrete adhering to the inner wall of the flow guiding pipe. If the concrete on the inner wall is not cleaned, it can easily block the flow guiding pipe. Therefore, it is necessary to study a flow guiding mechanism for concrete pouring, so as to solve the problem of residual concrete on the inner wall of the flow guiding pipe. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a concrete pouring guide mechanism to prevent concrete from sticking to the inner wall of the guide pipe and thus prevent blockage.

[0006] A concrete pouring guide mechanism includes a vehicle body, a guide pipe, and a first telescopic rod. The first telescopic rod is movably connected to the top of the vehicle body. The first telescopic rod is connected to the guide pipe via a connecting assembly. A side frame is fixed on the top of the vehicle body, located on one side of the first telescopic rod. A platform is fixedly installed inside the side frame. A motor is fixedly connected to a first rotating shaft above the platform. The first rotating shaft is rotatably connected to a second rotating shaft. A movable connecting assembly connecting rod is located at the tail of the second rotating shaft. An impact block is fixedly installed on the connecting rod. Two components are provided on the platform to limit the position of the impact block.

[0007] Preferably, a frame is fixedly mounted on the vehicle body, a second telescopic rod is provided inside the frame, a water spray head is provided above the second telescopic rod, a water pump is provided inside the frame, and the water pump is powered by a battery.

[0008] Preferably, the water nozzle input end is connected to the water pump output end through a pipe, the water pump input end is connected to a suction pipe, and the top of the water nozzle is sealed with a cover plate.

[0009] Preferably, a platform is fixedly provided above the vehicle body, and a pair of symmetrical tracks are fixedly installed above the platform. The tracks are movably connected to the impact block via sliders.

[0010] Preferably, the first telescopic rod can adjust the angle of the guide pipe, and a support column is connected above the vehicle body, the support column being movably connected to the guide pipe via a buckle.

[0011] Preferably, four symmetrical wheels are fixedly installed under the vehicle body, the head of the guide pipe is provided with a connection port, and the side of the vehicle frame is provided with an operation panel.

[0012] Beneficial effects:

[0013] 1. This utility model utilizes a rotating shaft to cause impact blocks to strike the guide pipe, vibrating the guide pipe and dislodging concrete from its inner wall, thus preventing blockages and extending its service life. The rotating shaft is fixed to the platform by a fixing assembly installed inside the side frame. A motor is connected to the first rotating shaft, which drives a second rotating shaft to generate thrust, causing the impact blocks to strike the guide pipe. This vibration dislodges the concrete adhering to the inner wall of the guide pipe, clearing blockages and promoting better flow.

[0014] 2. This utility model, by installing a water pump and spray nozzles, helps to clean residual concrete inside the vehicle frame, thereby improving the quality for future use. A second telescopic rod is installed inside the frame, with a spray nozzle mounted on its upper part. The spray nozzle is connected to the water pump via a pipe. After the guide pipe finishes its operation, pressing a button raises the telescopic rod to its final position, cleaning the guide pipe and removing residual concrete from its inner wall, thus extending the service life of the guide pipe.

[0025] Please see Figure 1-6 As shown, a concrete pouring guide mechanism includes [details omitted]. As a technical optimization of this utility model, [details omitted].

[0026] Furthermore, a concrete pouring guide mechanism includes a vehicle body 1, a guide pipe 2, and a first telescopic rod 4. The first telescopic rod 4 is movably connected to the top of the vehicle body 1. The first telescopic rod 4 is connected to the guide pipe 2 through a connecting assembly. A side frame 20 is fixed on the top of the vehicle body 1. The side frame 20 is located on one side of the first telescopic rod 4. A platform 15 is fixedly installed inside the side frame 20. A motor 10 is fixedly connected to the top of the platform 15 and a first rotating shaft 9 is fixedly connected. The first rotating shaft 9 is rotatably connected to a second rotating shaft 11. A movable connecting assembly connecting rod 12 is provided at the tail of the second rotating shaft 11. An impact block 3 is fixedly installed on the connecting rod 12. Two limiting assemblies 18 are provided on the platform 15 to limit the position of the impact block 3.

[0027] In the internal structural design of the equipment side frame 20, a stable mounting platform 15 is specifically designed. A power source motor 10 is precisely mounted on top of this platform 15. The output end of the motor 10 is securely connected to the first rotating shaft 9 via a coupling or direct drive. When the motor 10 starts operating, the rotational power it generates is efficiently transmitted through the first rotating shaft 9 to the linked second rotating shaft 11. This continuously generated thrust is directly applied to the impact block 3, driving the impact block 3 to periodically impact the guide pipe 2. This causes the guide pipe 2 to vibrate, and the vibration energy of the guide pipe 2 is directly transmitted to the concrete material flowing inside. The vibration effectively breaks down any agglomeration or bridging phenomena that may form within the concrete material, significantly reducing its viscosity and greatly improving its fluidity. This ensures that the concrete can flow continuously and smoothly within the pipe, fundamentally preventing pipe blockage problems caused by material stagnation or adhesion.

[0028] Furthermore, a frame 16 is fixedly mounted on the vehicle body 1. A second telescopic rod 8 is installed inside the frame 16, and a water nozzle 7 is installed above the second telescopic rod 8. A water pump 21 is installed inside the frame 16, and the water pump 21 is powered by a battery 25. The input end of the water nozzle 7 is connected to the output end of the water pump 21 through a pipe. The input end of the water pump 21 is connected to a suction pipe 19, and the top of the water nozzle 7 is sealed with a cover plate 5.

[0029] A second telescopic rod 8 is integrated into the internal structure of the frame 16. During normal operation or standby, the second telescopic rod 8 is fully retracted and fixed within the internal structural space of the frame 16, in its initial retracted position. Upon receiving a start command, the control system precisely activates the drive mechanism of the second telescopic rod 8. The actuator of the drive rod 8 extends outward at a constant speed along a predetermined linear trajectory. The end of the push rod of the second telescopic rod 8 is securely fitted with a water spray head 7. As the push rod extends at a constant speed, the water spray head 7 is stably and precisely pushed from its initial retracted position within the frame 16 to a pre-set cleaning endpoint position inside the guide pipe 2. This endpoint position is typically the area within the guide pipe 2 that requires focused cleaning.

[0030] Furthermore, a platform 14 is fixedly provided on the top of the vehicle body 1, and a pair of symmetrical tracks 13 are fixedly installed on the platform 14. The tracks 13 are movably connected to the impact block 3 through a slider.

[0031] The first telescopic rod 4 can adjust the angle of the guide pipe 2. A support column 17 is connected to the top of the vehicle body 1. The support column 17 is movably connected to the guide pipe 2 through the buckle 26.

[0032] Four symmetrical wheels 22 are fixedly installed on the lower part of the vehicle body 1. The head of the guide pipe 2 is provided with a connection port 23. The side of the vehicle frame 16 is provided with an operation panel 24.

[0033] The vehicle body 1 is connected to a first telescopic rod 4 and a support column 17. The angle of the guide pipe 2 can be adjusted by the first telescopic rod 4, which is a prototype of an electric push rod. A platform 14 is installed on the vehicle body 1, and a track 13 on the platform 14 restricts the position of the impact block 3, allowing the impact block 3 to move better. The wheels 22 under the vehicle body 1 can move the guide pipe 2 more easily and avoid soiling the workers' clothes.

[0034] Working Principle: A second telescopic rod 8 is integrated into the internal structure of the frame 16. During normal operation or standby, the second telescopic rod 8 is fully retracted and fixed within the internal structural space of the frame 16, in its initial retracted position. Upon receiving a start command, the control system precisely activates the drive mechanism of the second telescopic rod 8. The actuator of the drive rod 8 extends outward at a constant speed along a predetermined linear trajectory. The end of the push rod of the second telescopic rod 8 is securely fitted with a water spray head 7. As the push rod extends at a constant speed, the water spray head 7 is stably and precisely pushed from its initial retracted position within the frame 16 to a pre-set cleaning endpoint position inside the guide pipe 2. This endpoint position is typically the area within the guide pipe 2 that requires focused cleaning.

[0035] In the internal structural design of the equipment side frame 20, a stable mounting platform 15 is specifically designed. A power source motor 10 is precisely mounted on top of this platform 15. The output end of the motor 10 is securely connected to the first rotating shaft 9 via a coupling or direct drive. When the motor 10 starts operating, the rotational power it generates is efficiently transmitted through the first rotating shaft 9 to the linked second rotating shaft 11. This continuously generated thrust is directly applied to the impact block 3, driving the impact block 3 to periodically impact the guide pipe 2. This causes the guide pipe 2 to vibrate, and the vibration energy of the guide pipe 2 is directly transmitted to the concrete material flowing inside. The vibration effectively breaks down any agglomeration or bridging phenomena that may form within the concrete material, significantly reducing its viscosity and greatly improving its fluidity. This ensures that the concrete can flow continuously and smoothly within the pipe, fundamentally preventing pipe blockage problems caused by material stagnation or adhesion.
