Description

Technical Field

[0001] This utility model relates to the field of tunnel segment processing technology, specifically to a concrete hopper for tunnel segment production. Background Technology

[0002] Tunnel segments, also known as primary tunnel lining, are a crucial component of tunnel structures. The most commonly used segment types in tunnel construction include reinforced concrete segments, composite segments, and cast iron segments. These segments form the outermost barrier of the tunnel, and their quality directly affects the overall quality and safety of the tunnel, while also significantly influencing its waterproofing and durability. The fabrication process involves complex pouring techniques. First, the welded reinforcing cage is placed into the casting mold, and embedded parts are installed. Next, the hopper is opened, allowing concrete to be poured evenly into the mold. After pouring, the concrete surface needs to be finished and smoothed to ensure a flat and smooth finish. Finally, steam curing and demolding complete the segment pouring process.

[0003] However, in actual construction, the lack of a vibration mechanism easily leads to problems such as concrete segregation, hopper sticking, and hopper blockage. Furthermore, if the concrete residue on the inner wall of the hopper is not cleaned after discharge, a significant amount of hardened concrete will remain on the hopper's inner wall the next time it is used. This residue not only affects the discharge speed but also reduces the concrete's fluidity, thus lowering production efficiency. In addition, the residual concrete may affect the quality of the new concrete, leading to a decline in the performance of the tunnel segments. Cleaning the hopper requires a significant amount of manpower and time. Traditional cleaning methods typically require workers to manually remove the residual concrete from the hopper's inner wall, which is not only inefficient but also increases the workers' physical exertion.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a concrete hopper for segment production to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A concrete hopper for segment production includes a hopper body, with vibration motors fixedly connected to both sides of the hopper body. The vibration motors are electrically connected to a PLC controller. An aviation socket is connected to one side of the PLC controller via a wire. Hanging ears are fixedly connected to both sides of the top of the hopper body.

[0008] Furthermore, four fixing piles are fixedly connected inside the hopper body. The four fixing piles are located at the four corners inside the hopper body. Multiple mounting columns are fixed to the fixing piles. A plastic film is provided on the outside of the mounting columns. Mounting holes are provided on both sides of the plastic film. The mounting holes match the mounting columns. A fixing cover is provided on the top of the plastic film.

[0009] Furthermore, in order to secure the fixing cover and thus facilitate the fixing of the plastic film, two sets of buckles are fixedly connected to the fixing post. Each set of buckles consists of two buckles, which are symmetrically arranged. The fixing cover has an opening, through which the buckles pass and engage with the fixing cover.

[0010] Furthermore, to prevent concrete from entering the fixed cover through the opening, a rubber pad is installed inside the opening, and the rubber pad is connected to the fixed cover.

[0011] Furthermore, the bottom of the hopper body is provided with two baffles, and a rotating shaft is fixedly connected to one side of the baffle. The rotating shaft is connected to the fixed plate through a bearing, and one end of the rotating shaft passes through the fixed plate and is connected to the worm gear.

[0012] Furthermore, the fixing plate is fixedly connected to the hopper body.

[0013] Furthermore, in order to drive the shaft to rotate, a worm is meshed below the worm wheel, and the worm is connected to the output end of the drive motor via a connecting rod.

[0014] Furthermore, the connecting rod is connected to the connecting plate via a bearing, and the connecting plate is connected to the hopper body.

[0015] Furthermore, a mounting base is connected to one side of the drive motor, and the mounting base is connected to the hopper body.

[0016] Furthermore, the drive motor is electrically connected to the PLC controller.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) By setting a plastic film inside the hopper body and fixing it with mounting columns and fixing covers, concrete can be effectively prevented from directly contacting the inner wall of the hopper, reducing the possibility of concrete adhesion. After each use, only the plastic film needs to be replaced, which greatly simplifies the cleaning process and improves the cleaning efficiency. In addition, the plastic film itself is easy to clean, and even if there is a small amount of concrete residue, it can be cleaned by simple rinsing.

[0019] (2) By setting a vibration motor, it can assist the concrete to flow downward during the feeding process, making the feeding more efficient. Furthermore, by setting a worm gear mechanism and a drive motor, the opening and closing of the baffle can be easily controlled, thereby controlling the discharge of concrete. The operation is simple and the degree of automation is high. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] According to an embodiment of the present invention, a concrete hopper for segment production is provided.

[0030] Example 1

[0031] like Figures 1-5As shown, the concrete hopper for segment production according to an embodiment of this utility model includes a hopper body 1, which is truncated cone-shaped. The loading opening at the top of the hopper body 1 is 2.00 meters long and 1.82 meters wide, and the discharge opening is 1.2 meters long and 0.6 meters wide. Four fixing piles 6 are fixedly connected inside the hopper body 1, located at the four corners inside the hopper body 1. Multiple mounting posts 7 are fixed to the fixing piles 6. A plastic film 8 is provided on the outside of the mounting posts 7. The plastic film 8 can be laid on the outer side of the inner wall of the hopper body 1. This plastic film 8 can be a high-density polyethylene film, which can effectively prevent moisture penetration, ensure the fluidity of the concrete in the hopper, and avoid concrete solidification and adhesion problems caused by moisture penetration. Furthermore, the high-density polyethylene film has high mechanical strength and wear resistance, and can withstand greater pressure. The plastic film 8 is resistant to friction and not easily damaged, ensuring the normal operation of the hopper. The plastic film 8 has mounting holes 9 on both sides, which match the mounting posts 7. A fixing cover 10 is provided above the plastic film 8. Two sets of buckles 11 are fixedly connected to the fixing posts 6. Each set of buckles 11 consists of two buckles, which are symmetrically arranged. One end of the buckle 11 is triangular. The fixing cover 10 has an opening 12. The buckles 11 pass through the opening 12 and engage with the fixing cover 10. A rubber pad 13 is provided inside the opening 12. The rubber pad 13 is connected to the fixing cover 10 and is located in the middle of the opening 12 to prevent concrete from entering the fixing cover 10 from the middle of the opening 12. The rubber pad 13 can deform as the buckles 11 move. When installing and removing the fixing cover 10, the rubber pad 13 will not obstruct the operation. With the above method, when installing the plastic film 8, the mounting holes 9 on both sides of the plastic film 8 are installed on the mounting post 7. Then, the opening 12 on the fixing cover 10 is aligned with the buckle 11, and the fixing cover 10 is pressed down. During the pressing process, the buckle 11 will deform, allowing one triangular end of the buckle 11 to pass smoothly through the opening 12 and be placed on the outside of the fixing cover 10. This allows the fixing cover 10 to be firmly fixed to the outside of the fixing post 6, thereby pressing the plastic film 8 to ensure that it will not shift or fall off during use. When it is necessary to remove the plastic film 8, the buckle 11 can be squeezed towards the middle of the opening 12, and then the fixing cover 10 can be moved outward to disengage the fixing cover 10 from the buckle 11, making it easy to remove the fixing cover 10. At this time, the plastic film 8 is also released, which can be easily disassembled and replaced.

[0032] Example 2

[0033] like Figures 1-2As shown, vibration motors 2 are fixedly connected to both sides of the outer side of the hopper body 1. The vibration motors 2 are electrically connected to the PLC controller 3. The PLC controller 3 has a built-in wireless transmission module, which enables the PLC controller 3 to communicate wirelessly with the crane controller. An aviation socket 4 is connected to one side of the PLC controller 3 via a wire. Hanging ears 5 are fixedly connected to both sides of the top of the hopper body 1. Two baffles 14 are provided at the bottom of the hopper body 1. A rotating shaft 15 is fixedly connected to one side of the baffle 14. The rotating shaft 15 is connected to a fixed plate 16 via a bearing. One end of the rotating shaft 15 passes through the fixed plate 16 and is connected to a worm gear 17. The fixed plate 16 is fixedly connected to the hopper body 1. A worm 18 is meshed below the worm gear 17. The worm 18 is connected to the output end of the drive motor 20 via a connecting rod 19. The connecting rod 19 is connected to a connecting plate 21 via a bearing. The connecting plate 21 is connected to the hopper body 1. A mounting base 22 is connected to one side of the drive motor 20. The mounting base 22 is connected to the hopper body 1. The above solution allows for the transportation of concrete using a dedicated on-site hopper transport vehicle, preventing displacement of the hopper during transport and ensuring the safety of concrete delivery. The hopper, combined with a dedicated concrete transport vehicle, can quickly transport concrete to the pouring site, saving at least 10 minutes per batch compared to a chute-type hopper. Upon arrival at the site, a dedicated crane and lifting equipment, along with the lugs 5, can be used to move the hopper. Connecting the aviation plug to the aviation socket 4 provides power to the electrical components on the hopper. Furthermore, the built-in wireless transmission module of the PLC controller 3 enables wireless communication with the crane controller. Through wireless communication, the crane controller can send commands to the PLC controller 3, thereby controlling the working status of the vibration motor 2 and the drive motor 20. When concrete needs to be poured into the mold, the crane moves the hopper above the mold, and the crane controller remotely starts the drive motor 20, which drives the connecting rod 19 and the worm gear 18 to rotate. The rotation of the worm gear 18 drives the worm wheel 17 and the rotating shaft 15 to rotate, thereby opening the baffle 14. The transmission method of the worm gear 18 and the worm wheel 17 has high transmission accuracy and stability, ensuring the smooth opening of the baffle 14 and avoiding concrete splashing or waste caused by the sudden opening of the baffle 14. In addition, this opening method can adjust the speed and rotation direction of the drive motor 20 according to actual needs, thereby controlling the opening speed and angle of the baffle 14 to meet the requirements of different pouring processes. While the baffle 14 is opened, the vibration motor 2 can be started. The vibration motor 2 generates periodic vibrations to help the concrete flow downwards during the pouring process, preventing the concrete from clogging or bridging due to viscosity or friction between particles. This design not only improves the efficiency of concrete delivery but also reduces the need for manual intervention, making the entire delivery process smoother and more efficient.

[0034] In summary, by utilizing the above-mentioned technical solution of this utility model, by setting a plastic film 8 inside the hopper body 1 and fixing it with mounting columns 7 and fixing covers 10, it is possible to effectively prevent concrete from directly contacting the inner wall of the hopper, reducing the possibility of concrete adhesion. After each use, only the plastic film 8 needs to be replaced, which greatly simplifies the cleaning process and improves cleaning efficiency. Furthermore, the plastic film 8 itself is easy to clean, and even if there is a small amount of concrete residue, it can be cleaned by simple rinsing. In addition, by setting a vibration motor 2, it can assist the concrete to flow downward during the feeding process, making the feeding more efficient. Moreover, by setting a worm gear mechanism and a drive motor 20, the opening and closing of the baffle 14 can be easily controlled, thereby controlling the discharge of concrete. The operation is simple and highly automated.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
