Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a concrete pump pipe connection structure. Background Technology

[0002] The connection structure of concrete pump pipes is a crucial component for ensuring the stable operation of concrete conveying systems. Its core function is to achieve rapid connection and sealing between different pump pipes, preventing leakage during the conveying of high-strength concrete. Common connection methods include flange connections and quick-clamp connections. Flange connections, secured with flanges and bolts, are suitable for large-diameter pump pipes or high-pressure conditions, offering strong sealing performance but relatively cumbersome disassembly. Quick-clamp connections rely on the snap-fit ​​structure of specialized pipe clamps for rapid assembly and disassembly, widely used in temporary and frequent relocation scenarios for small and medium-diameter pump pipes. They are convenient to operate and can accommodate certain angle adjustments. This type of connection structure must simultaneously meet strength and sealing requirements, typically constructed from wear-resistant alloy materials. The pipe end interfaces are precision-machined to ensure a proper fit, and some structures also incorporate rubber sealing rings to enhance the sealing effect. In practical applications, the selection of the connection structure must consider factors such as conveying pressure, concrete aggregate particle size, and construction environment to ensure the efficient and safe operation of the pump pipe system.

[0003] A search revealed Chinese Patent Publication No. CN220435702U, which discloses a connection structure for a concrete pumping pipe in building construction, belonging to the field of pumping pipe connection technology. The connection handle has internally threaded pipes at both ends, symmetrically arranged. Each internally threaded pipe is threadedly connected to a corresponding threaded rod. One end of the threaded rod rotatably passes through the internally threaded pipe and is rotatably connected to a corresponding fixing mechanism. Symmetrical shock-absorbing mechanisms are provided on both sides of each internally threaded pipe. This invention, through the abutment of the threaded rod and the clamping and fixing of the two threaded rods, better prevents loosening caused by vibration. The combination of damping springs and shock-absorbing cotton reduces the vibration and noise of the pumping pipe, improving the construction working environment and extending the service life of the pumping pipe. Although this device achieves the goals of reducing pumping pipe vibration and noise, improving the construction working environment, and extending the service life of the pumping pipe, it cannot control the extension and retraction of the filter element and is not suitable for various application scenarios.

The addition of fixing plate two further enhances the structural strength and stability of the entire fixing component, enabling it to better perform its fixing and supporting functions in application, and significantly improving the overall performance of the fixing component.

[0015] As a further description of the above technical solution: The clamping mechanism includes two clamps, the inner walls of the two clamps are rotatably connected to the outer wall of the connecting sleeve and are equidistantly distributed, and the outer walls of the clamps are fixedly connected with bolts.

Similarly, the outer wall of sealing ring two is also fixedly connected to the bottom area of ​​the inner wall of the connecting sleeve to achieve a bottom seal. These two sealing rings are symmetrically distributed on the inner wall of the connecting sleeve, thus forming a uniform and comprehensive seal throughout the entire inner wall of the connecting sleeve, effectively preventing any possible leakage problems.

[0019] As a further description of the above technical solution: The pump pipe mechanism includes an external thread, the outer wall of which is threadedly connected to the inner wall of the connecting sleeve, and a pump body connecting pipe is fixedly connected to the bottom of the external thread.

In addition, a pump body connecting pipe is firmly fixedly connected to the bottom position of the external thread structure, ensuring that a stable and reliable connection relationship is formed between the pump body connecting pipe and the external thread structure, thereby ensuring that the entire pump pipe mechanism has good stability and sealing performance during operation.

[0021] This utility model has the following beneficial effects: 1. In this utility model, when the filter element is not needed, the threaded sleeve is rotated. At this time, the threaded sleeve will rotate on the surface of the threaded column. Then the threaded sleeve will drive the fixed connecting rod to move outward. At the same time, the fixed connecting rod will drive the filter element to move outward. At this time, the filter element leaves the inside of the connecting sleeve. When the filter element needs to be cleaned, the cap is removed. At this time, the inside of the connecting shell is rinsed through the water inlet pipe. At this time, the filter element will be rinsed by the water flow. This realizes the ability to freely control the extension and retraction of the filter element and to clean it. 2. In this utility model, after the connecting sleeve is connected to the pump body connecting pipe, the bolt is rotated so that the clamp initially fixes the connecting sleeve and the pump body connecting pipe together. At this time, the hydraulic rod is activated, and the hydraulic rod will push the push rod to move inward. At this time, the push rod will squeeze against the inner wall of the connecting sleeve. At the same time, the fixing plate 2 will radially shrink the clamp, making the fixing of the connecting sleeve and the pump body connecting pipe more stable. This realizes convenient fixing connection and makes the fixing more stable through the squeezing of the hydraulic rod, preventing the connecting sleeve from falling off due to excessive water pressure.

[0029] Working principle: First, the pump body connecting pipe 601 is installed on both ends of the connecting sleeve 1 through the external thread 602. Then, the connecting sleeve 1 is fixed. At this time, the pump body can be opened for pumping. Impurities will pass through the filter element 201 and remain on the surface of the filter element 201. When the filter element 201 is no longer needed, the threaded sleeve 203 is rotated. The threaded sleeve 203 will rotate on the surface of the threaded post 204. Then, the threaded sleeve 203 will drive the fixed connecting rod 202 to move outward. At the same time, the fixed connecting rod 202 will drive the filter element 201 to move outward. At this time, the filter element 201 leaves the inside of the connecting sleeve 1. When the filter element 201 needs to be cleaned, the cap 2053 is removed. At this time, the inside of the connecting shell 2051 is rinsed through the water inlet pipe 2052. The filter element 201 will be rinsed by the water flow. This realizes the ability to freely control the extension and retraction of the filter element 201 and to clean it. After the connecting sleeve 1 is connected to the pump body connecting pipe 601, rotate the bolt 402 so that the clamp 401 initially fixes the connecting sleeve 1 and the pump body connecting pipe 601 together. At this time, start the hydraulic rod 305. The hydraulic rod 305 will push the push rod 303 to move inward. At this time, the push rod 303 will squeeze against the inner wall of the connecting sleeve 1. At the same time, the fixing plate 3062 will radially shrink the clamp 401, making the fixing of the connecting sleeve 1 and the pump body connecting pipe 601 more stable. This achieves convenient fixing and connection, and the squeezing of the hydraulic rod 305 makes the fixing more stable, preventing the connecting sleeve 1 from falling off due to excessive water pressure.
