Description

Technical Field

[0001] This utility model relates to the field of cast stone composite pipe structure technology, and in particular to an impact-resistant cast stone composite pipe. Background Technology

[0002] In modern industrial and infrastructure construction, pipeline systems are a key component for transporting various media, and their performance and reliability directly affect the safety and efficiency of the entire project. Cast stone composite pipes have been widely used in chemical, metallurgical, power, and mining industries due to their good wear resistance, corrosion resistance, and high strength.

[0003] Currently, traditional cast stone composite pipes have many shortcomings in terms of impact resistance. On the one hand, their structural design is relatively simple, usually consisting only of an inner and outer pipe, lacking effective impact-resistant elements and buffer structures. When subjected to large impact forces, they cannot effectively disperse and absorb energy, easily causing local damage to the pipeline. On the other hand, the connection methods of traditional cast stone composite pipes also have defects. For example, the use of welding and flange connections can easily lead to loosening and leakage at the connection points when subjected to impact, further reducing the overall impact resistance of the pipeline. In addition, the material selection and manufacturing process of existing cast stone composite pipes also limit the improvement of their impact resistance, making it difficult to meet the requirements of use under complex working conditions. Therefore, this application designs an impact-resistant cast stone composite pipe to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an impact-resistant cast stone composite pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an impact-resistant cast stone composite pipe, comprising an outer pipe, an inner pipe inside the outer pipe, a number of impact-resistant elements symmetrically arranged at equal intervals between the outer pipe and the inner pipe, an elastic element provided at the gap between the impact-resistant elements, the elastic element being located between the outer pipe and the inner pipe, and a number of connecting components equidistantly spaced on the outer pipe.

[0006] Preferably, the inner pipe has a mating hole for inserting an impact-resistant element, a spring is fixed to the bottom end of the mating hole, and the protruding end of the inserted impact-resistant element abuts against the spring.

[0007] Preferably, the outer pipe, the inner pipe, and the elastic element are all provided with positioning grooves for engaging and fixing with the connecting component. The outer pipe is fixedly provided with a mounting base, and the connecting component is limited and engaged with the mounting base.

[0008] Preferably, the connecting assembly consists of a locking screw, an inner shaft, and an outer shaft. The outer layer of the locking screw is rotatably engaged with the mounting base, the inner shaft is rotatably engaged with the lower end of the locking screw, and the outer shaft is fixedly connected to the lower end of the mounting base.

[0009] Preferably, the inner shaft is provided with a plurality of fixed blocks that are equidistantly hinged, and the outer shaft is provided with limiting blocks that are equidistantly positioned to limit and block the fixed blocks.

[0010] Preferably, the impact-resistant element and the elastic element are made of impact-resistant material, and the two ends of the elastic element are tightly fitted to the inner pipe and the impact-resistant element, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, by combining the impact-resistant element with the spring, the impact-resistant element and the entire structure can be restored to their initial position after an impact using their own elasticity, thereby improving the impact resistance stability of the pipeline. Furthermore, by combining the impact-resistant element with the elastic element, the impact force can be dispersed and absorbed from all directions, greatly improving the impact resistance of the pipeline and thus enhancing the impact resistance of the pipeline. Ultimately, this solves the problem of poor impact resistance of existing cast stone composite pipes. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses an impact-resistant cast stone composite pipe, comprising an outer pipe 1, an inner pipe 2 inside the outer pipe 1, several impact-resistant elements 3 symmetrically arranged at equal intervals between the outer pipe 1 and the inner pipe 2, and elastic elements 4 located between the outer pipe 1 and the inner pipe 2 at the gaps between the impact-resistant elements 3. Multiple connecting components are equidistantly arranged on the outer pipe 1. The design of the inner and outer pipe structure provides a basic framework for the entire device. The inner pipe 2 can be used to transport media, while the outer pipe 1 provides protection and support, enhancing the overall stability and durability. The inner pipe 2 has a mating hole for inserting the impact-resistant elements 3, and a spring 5 is fixed to the bottom end of the mating hole. The extended end of 3 abuts against the spring 5. The impact-resistant element 3 can effectively absorb the impact force from the outside and protect the inner pipe 2 from damage by a large impact. The elastic element 4 can buffer the impact force of the impact-resistant element 3 on the one hand, and restore the structure to its initial state after being impacted on the other hand, thereby improving the impact resistance and buffering capacity of the device. The outer pipe 1, the inner pipe 2 and the elastic element 4 are all provided with positioning grooves 11 for locking and fixing with the connecting components. The outer pipe 1 is fixedly provided with a mounting seat 6. The connecting components are limited and locked in the mounting seat 6. The outer pipe 1, the inner pipe 2 and the elastic element 4 can be stably connected to ensure that the components do not undergo relative displacement during operation and ensure the structural stability of the entire device.

[0020] In this invention, the connecting assembly consists of a locking screw 9, an inner shaft 10, and an outer shaft 12. The outer layer of the locking screw 9 is rotatably engaged with the mounting base 6, the inner shaft 10 is rotatably engaged with the lower end of the locking screw 9, and the outer shaft 12 is fixedly connected to the lower end of the mounting base 6. Through the setting of the limiting block 7, when the inner shaft 10 is pushed, the retraction fixing block 8 is blocked, thereby unlocking the fixing block 8 and the positioning groove 11. This structural design facilitates the installation and disassembly of the various components of the device, and facilitates subsequent maintenance and repair work. Multiple fixing blocks 8 are equidistantly hinged on the inner shaft 10. The outer shaft 12 is provided with limit blocks 7 at equal intervals for limiting and blocking the fixing block 8. By setting the limit blocks 7, the inner shaft 10 can be pushed to block the retraction of the fixing block 8, thereby unlocking the fixing block 8 and the positioning groove 11. The impact-resistant element 3 and the elastic element 4 are made of impact-resistant material. The two ends of the elastic element 4 are tightly fitted to the inner pipe 2 and the impact-resistant element 3, respectively. The impact-resistant element 3 and the elastic element 4 are made of impact-resistant material, which can maximize their impact resistance and buffering function. The tight fit design ensures the effective transmission of force and buffering effect.

[0021] Working Principle: When using this invention, the equipment is first assembled and installed. The impact-resistant element 3 directly bears most of the impact force. Since the impact-resistant elements 3 are symmetrically distributed at equal intervals between the outer pipe 1 and the inner pipe 2, they can disperse and absorb the impact force from all directions. Simultaneously, the elastic element 4 at the gaps between the impact-resistant elements 3 begins to function, buffering the impact force transmitted from the impact-resistant elements 3 and, after the impact, using its own elasticity, restoring the impact-resistant elements 3 and the entire structure to their initial positions. The spring 5 at the bottom of the connecting hole of the inner pipe 2 further buffers the impact force of the impact-resistant elements 3, assisting in... Reset; In terms of device connection, the connecting components play a key role; During normal operation, the fixing block 8 is locked in the positioning groove 11, firmly connecting the outer pipe 1, inner pipe 2 and elastic element 4 together; When installation, disassembly or maintenance is required, the inner shaft 10 is pushed, at which time the limiting block 7 blocks the retracting fixing block 8, causing it to disengage from the positioning groove 11, thereby unlocking the connection between the components for convenient operation; Through reasonable structural design and material selection, this device achieves good impact resistance and convenient installation and maintenance functions, and can operate stably in complex working environments. The use of the device ends here.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
