Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a structural column filling device. Background Technology

[0002] To improve the seismic performance of building structures, relevant codes require the installation of reinforced concrete structural columns within the masonry structure, connected to ring beams, to jointly bear lateral loads and enhance the overall integrity and stability of the masonry structure. Concrete pouring is a key step in the construction of these structural columns. Currently, concrete pouring trolleys are commonly used as the primary construction equipment.

[0003] When using a concrete pouring trolley, the end of the discharge pipe needs to be precisely aligned with the pouring port of the structural column formwork to ensure that the concrete discharged from the discharge pipe can be injected into the formwork. However, due to fluctuations in concrete delivery pressure and misalignment of the pipe ends, concrete splashing is prone to occur, resulting in material waste and pollution of the working environment. Furthermore, when moving the discharge pipe after pouring, residual concrete inside the pipe can easily flow out freely, further increasing the material loss rate. Based on this, this application proposes a structural column pouring device. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides an embodiment: Please refer to Figures 1-6 A concrete pouring device for structural columns includes a mobile vehicle body 1. The top of the mobile vehicle body 1 is equipped with a conveying structure for conveying concrete used in the construction of structural columns. The conveying structure includes a feed hopper 2 connected to the mobile vehicle body 1. A screw conveyor 3 is provided on one side of the feed hopper 2. The discharge end of the screw conveyor 3 is connected to a connecting pipe 7. A filter screen 11 is provided at the top of the inner cavity of the feed hopper 2. When using this device, workers can put the concrete used for the construction of structural columns into the feed hopper 2. The screw conveyor 3 conveys the concrete, and the filter screen 11 can filter the concrete to avoid the presence of impurities such as stones with excessive diameter in the concrete, prevent large particles from clogging the screw conveyor 3, and ensure the construction quality of the structural columns.

[0017] In this application, the material conveying structure is in a state of active connection with the mobile vehicle body 1. The mobile vehicle body 1 is provided with a second drive structure 6, which can drive the material conveying structure to rotate and change the tilt angle of the material conveying structure, so that the device can meet a variety of needs and improve the adaptability of the device. The second drive structure 6 is the prior art, which only needs to realize the change of the deflection angle of the material conveying structure and instantaneous locking.

[0018] The bottom of the inner cavity of the feed hopper 2 is inclined, and the feed end of the screw conveyor 3 is located at the bottom of the inner cavity of the feed hopper 2. A third drive structure 13 is provided on the feed hopper 2, and the screw conveyor 3 is driven by the third drive structure 13. In Embodiment 1 of this application, a synchronous sprocket is provided at the end of the output shaft of the third drive structure 13, and another synchronous sprocket is provided at the power output end of the screw conveyor 3. The two synchronous sprockets are connected by a synchronous chain drive.

[0019] Both the third drive structure 13 and the screw conveyor 3 are existing technologies. The third drive structure 13 only needs to be able to realize the rotation and instantaneous locking of the power output end of the screw conveyor 3, and the screw conveyor 3 only needs to realize the conveying of concrete for the construction of the structural column.

[0020] As can be seen from the above description, when using this device, the discharge direction of the conveying structure can be changed, thereby improving the adaptability of the device.

[0021] The discharge end of the conveying structure is connected to the discharge assembly 5 via a connecting pipe 7. The length and material of the connecting pipe 7 can be set according to requirements and are not limited here. The discharge assembly 5 includes a discharge pipe 14 connected to the connecting pipe 7. An outer pipe 8 is fixedly connected to the outer ring of the discharge pipe 14, forming a cavity between the outer pipe 8 and the discharge pipe 14. A support rod 17 is movably connected within the cavity. The end of the support rod 17 away from the connecting pipe 7 extends to the outside of the discharge pipe 14 and is connected to a baffle plate. When in use, the baffle plate can limit the concrete discharged from the discharge pipe 14, restricting the concrete spraying distance, preventing concrete from spraying outside the pouring port, and reducing the impact force of the concrete on the structural column mold. The baffle plate has a hollow structure, and the inner cavity of the baffle plate is filled with a buffer pad to reduce the impact force of the concrete on the baffle plate. The material of the buffer pad can be set according to requirements and is not limited here.

[0022] The baffle plate includes a fixed ring 9 connected to a support rod 17 and a rotating plate 10 adapted to the inner cavity of the fixed ring 9. The rotating plate 10 is movably connected to the fixed ring 9. A first driving structure 16 is provided on the top of the fixed ring 9. The rotating plate 10 is driven by the first driving structure 16, which can drive the rotating plate 10 to rotate. The positions of the two sides of the rotating plate 10 can be changed. The first driving structure 16 is existing technology and only needs to satisfy the requirements of rotating plate 10 rotation and instantaneous locking. The surface of the baffle plate is provided with an anti-stick coating. The anti-stick coating facilitates the separation of concrete from the baffle plate. The material of the anti-stick coating can be set according to requirements and is not limited here.

[0023] A sealing tube 18 is movably connected inside the cavity. The sealing tube 18 is movably sleeved on the outside of the discharge tube 14. Sealing gaskets are provided on the inner wall and end of the sealing tube 18. The sealing gaskets can improve the sealing performance between the sealing tube 18 and the discharge tube 14. The sealing tube 18 is adapted to the rotating plate 10. When the sealing tube 18 and the rotating plate 10 are tightly fitted, the sealing gaskets can improve the sealing performance between the sealing tube 18 and the rotating plate 10. The baffle plate can seal the discharge end of the discharge assembly 5 to prevent the residual concrete inside the discharge assembly 5 from flowing out when it is transferred.

[0024] An annular airbag 19 is provided at one end of the cavity near the baffle plate. When the sealing tube 18 is located in the cavity, the annular airbag 19 can block the opening end of the cavity. The annular airbag 19 protects the sealing tube 18 and prevents concrete from sliding down the discharge pipe 14 from contaminating the end of the sealing tube 18. When the sealing tube 18 is squeezed by external force, the annular airbag 19 can deform, and the sealing tube 18 can enter and exit the cavity under the action of external force.

[0025] The sealing tube 18 and the support rod 17 are connected by a linkage structure, which includes a pull rope 4 movably connected to the cavity, a spring 12 connected to the outer tube 8, and an electric telescopic rod 15 connected to the outer tube 8. The sealing tube 18 is connected to the outer tube 8 via the electric telescopic rod 15, and the support rod 17 is connected to the outer tube 8 via the spring 12. One end of the pull rope 4 is connected to the sealing tube 18, and the other end of the pull rope 4 is connected to the end of the support rod 17 away from the baffle plate. The two ends of the pull rope 4 are parallel to each other. The electric telescopic rod 15 drives the sealing tube... When the sealing pipe 18 moves, the sealing pipe 18 can drive the support rod 17 to move through the pull rope 4, and the sealing pipe 18 and the support rod 17 move in opposite directions. Under the action of the electric telescopic rod 15, the sealing pipe 18 can contact the rotating plate 10 to seal the discharge end of the discharge pipe 14. At this time, there is a gap between the rotating plate 10 and the discharge pipe 14 to prevent the concrete adhering to the discharge end of the discharge pipe 14 from affecting the sealing performance. The gap between the rotating plate 10 and the discharge pipe 14 can be set according to the requirements and is not limited here.

[0026] As can be seen from the above description, when the discharge end of the discharge pipe 14 is blocked, the blocking pipe 18 and the baffle plate can move closer to each other to improve the blocking efficiency. And during the opening process of the discharge end of the discharge pipe 14, the blocking pipe 18 and the baffle plate can move further apart to improve the opening efficiency of the discharge end of the discharge pipe 14.

[0027] All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, appropriate controllers can be selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between the various electrical components are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0028] In summary: When using the structural column filling device, the operator uses the mobile vehicle 1 to change the position of the filling device, and adjusts the deflection angle of the conveying structure through the second drive structure 6 as needed. After the operator uses appropriate clamps and other tools to fix the position of the discharge component, the controller in the device drives the electric telescopic rod 15 to work. The electric telescopic rod 15 drives the sealing pipe 18 to move. The sealing pipe 18 and the baffle plate gradually move away from each other until the sealing pipe 18 moves into the cavity. The annular airbag 19 protects the sealing pipe 18. When using this device, workers put the concrete for the construction of the structural column into the feed hopper 2, and the filter screen 11 can filter the concrete to avoid the presence of impurities such as stones with excessive diameter in the concrete, and prevent large particles from clogging the screw conveyor 3, thus ensuring the construction quality of the structural column. The third drive structure 13 drives the screw conveyor 3 to transport the concrete. The concrete enters the structural column forming mold through the connecting pipe 7 and the discharge pipe 14. During the concrete discharge process, the baffle plate limits the concrete, restricts the spray distance of the concrete, prevents the concrete from spraying outside the mold pouring port, and reduces the impact force of the concrete on the structural column mold. After the pouring is completed, the screw conveyor 3 stops working. The controller in the device controls the first drive structure 16 to drive the rotating plate 10 to rotate until the rotating plate 10 rotates 180°. At this time, the side of the rotating plate 10 without concrete is facing the discharge pipe 14. The controller in the device controls the electric telescopic rod 15 to work. The electric telescopic rod 15 drives the sealing pipe 18 to move in the opposite direction. Under the action of the linkage structure, the sealing pipe 18 and the baffle plate approach each other until the sealing pipe 18 and the rotating plate 10 are tightly attached. The baffle plate is used to seal the discharge end of the discharge component 5 to prevent the residual concrete inside the discharge component 5 from flowing out when it moves.
