Description

Technical Field

[0001] This utility model relates to the field of concrete conveying technology, specifically a high-performance concrete conveying structure. Background Technology

[0002] High-performance concrete is an innovative concrete material with durability as its core design standard. While ensuring high strength, it also possesses excellent workability and high volume stability. Its most prominent core characteristics encompass high durability, good workability, high volume stability, and economic applicability. For these reasons, high-performance concrete has been widely used in many fields, including bridge engineering, high-rise buildings, and special environmental engineering.

[0003] High-performance concrete conveying structures already exist, and in actual construction, telescopic belt conveyors are generally used to transport concrete to different construction sites. However, after the extension is completed, a gap forms between the extended end and the fixed end of this type of structure. At this point, the belt above the gap may not receive sufficient and effective support. During the concrete conveying process, the belt bears the weight of the concrete, and over time, this can easily lead to belt tearing, severely affecting the conveying efficiency. Summary of the Invention

[0004] Purpose of the utility model: This utility model provides a high-performance concrete conveying structure with a seamless connection between the protruding end and the fixed end, excellent belt support, and good concrete conveying effect.

[0007] The tensioning conveyor components are symmetrically arranged and fixed to the bottom of the fixed conveyor components;

[0008] Active conveyor components;

[0009] A motor-driven conveying component, wherein the motor-driven conveying component is fixed to the end of the hydraulic telescopic component away from the fixed conveying component;

[0010] A conveyor belt, which is tightly fitted around the outside of the fixed conveyor component, the movable conveyor component, and the tensioning conveyor component;

[0011] The hinge rod components are symmetrically arranged and slidably connected to symmetrically arranged hydraulic telescopic components. The symmetrically arranged hinge rod components are rotatably connected to a movable conveying component.

[0012] The hinge rod component includes two fixed hinge rods and several continuously connected movable hinge rods. The ends of the fixed hinge rods that are close to each other are rotatably connected to one end of the movable hinge rods, and the other ends of the two fixed hinge rods that are far apart from each other are respectively connected to the motor conveying component and the fixed conveying component; the several continuously connected movable hinge rods are rotatably connected to each other.

[0013] The gap between the fixed conveying component and the movable conveying component is the same, and the conveyor belt maintains a uniform tension during the conveying process; automatic tensioning and gap adjustment are achieved through hydraulic telescopic components and tensioning conveying components.

[0014] Furthermore, the fixed conveying component includes a fixed frame, fixed conveying rollers, and limiting blocks; a plurality of fixed conveying rollers are rotatably connected at even intervals on the inner side of the top of the fixed frame, and limiting blocks are symmetrically fixedly connected to both sides of one end of the fixed frame.

[0015] Furthermore, the hydraulic telescopic component includes a telescopic hydraulic cylinder, a sliding plate, and a sliding groove; one end of the sliding plate is fixedly connected to the output end of the telescopic hydraulic cylinder, and the sliding plate is provided with a sliding groove; the symmetrically arranged telescopic hydraulic cylinders are respectively fixedly connected to both sides of the fixed frame.

[0016] Furthermore, the sliding plate is slidably connected to the limiting block.

[0017] Furthermore, the tensioning conveying component includes a tensioning roller, a roller fixing block, and a tensioning hydraulic cylinder. The two ends of the tensioning roller are rotatably connected to the roller fixing block, and the top of the roller fixing block is fixedly connected to the tensioning hydraulic cylinder. The top of the tensioning hydraulic cylinder is fixedly connected to both sides of the fixing frame.

[0018] Furthermore, the movable conveying component includes several movable rollers and sliders; both ends of the movable rollers pass through the middle of the movable hinge rod and are rotatably connected to the sliders.

[0019] Furthermore, the slider is slidably connected to the sliding plate via a groove.

[0020] Furthermore, the motor conveying component includes a movable conveying roller and a motor; the movable conveying roller is rotatably connected to the motor.

[0021] Furthermore, the other ends of the two fixed hinge rods, which are far apart from each other, are rotatably connected to the movable conveyor roller and the fixed frame, respectively; one end of the movable conveyor roller passes through one end of a fixed hinge rod and the sliding plate and is rotatably connected to the motor, and the other end of the movable conveyor roller passes through one section of a fixed hinge rod on the opposite side and is rotatably connected to the sliding plate on the opposite side.

[0023] Working principle: The motor drives the movable conveyor roller to rotate, which in turn drives the conveyor belt to move and transport concrete. When concrete needs to be transported to different construction sites, two telescopic hydraulic cylinders drive two sliding plates to extend along the limit blocks, which in turn drives the motor conveying components to extend. This causes the movable conveyor roller to drive two fixed hinge rods at both ends. The two fixed hinge rods drive the movable hinge rods, which in turn drive the movable roller to slide along the slide groove through the sliders at both ends, spreading it evenly and supporting the conveyor belt. During this process, two tensioning hydraulic cylinders drive two roller fixing blocks to rise, which in turn drives the tensioning roller to rise and loosen the conveyor belt.

[0024] Beneficial effects: Compared with the prior art, the present invention has the following effects:

[0025] 1. This utility model uses two telescopic hydraulic cylinders to drive two sliding plates to extend, which in turn drives the motor conveying component to extend. The movable conveying roller drives two fixed hinge rods at both ends, causing the two fixed hinge rods to pull the movable hinge rod, which in turn drives multiple continuously connected movable hinge rods to rotate. The multiple continuously connected movable hinge rods drive the movable roller, causing the movable roller to drive two sliders at both ends to slide along the slide groove, thereby making the multiple movable rollers evenly open. This allows the multiple movable rollers to open evenly when the motor conveying component extends, effectively supporting the conveyor belt and preventing the belt from tearing due to excessive weight over a long period of time, thus extending the belt's service life.

[0026] 2. This utility model uses two tensioning hydraulic cylinders to drive the tensioning roller between the two roller fixing blocks to move, which can assist the two hydraulic telescopic components in adjusting the conveyor belt. When the two hydraulic telescopic components extend, the conveyor belt is loosened; when the two hydraulic telescopic components retract, the conveyor belt is tensioned, thus avoiding the conveyor belt being too loose or too tight and ensuring its high efficiency and stability.

[0027] 3. This utility model has a compact structure, low cost, and strong applicability. Attached Figure Description
