Abstract
Description
Technical Field
[0001] This utility model relates to the field of conduit connection technology, specifically a quick-release concrete conduit. Background Technology
[0002] Concrete tremie pipes are specialized pipelines used to transport concrete slurry. They are primarily used in underwater casting of bored piles for hydraulic and hydropower projects, large bridge projects, railway projects, highway projects, and high-rise building foundations. They play a crucial role in construction, especially in situations requiring concrete casting in underwater or underground environments.
[0003] Currently, most underwater concrete pouring pipe connections use flange connections and threaded connections. While these methods ensure tensile strength and airtightness, they result in low construction efficiency and require the use of installation tools. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quick-release concrete conduit to solve the problems of cumbersome connection methods for existing concrete pouring conduits, which not only require the use of installation tools but also result in low construction efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release concrete conduit, comprising a first connecting pipe and a second connecting pipe that mate with each other. The first connecting pipe and the second connecting pipe have coaxial butt grooves and mounting grooves on their facing surfaces, and a rubber sealing ring is installed in the mounting groove. The facing surfaces of the first connecting pipe and the second connecting pipe are also provided with corresponding insert posts and insert holes. A fixing hole is provided on the side of the insert post, and a fixing component that mates with the fixing hole is installed inside the insert hole. The outer surfaces of the first connecting pipe and the second connecting pipe are provided with corresponding connecting blocks and connecting sleeves.
[0006] Preferably, two docking grooves and two mounting grooves are provided, and the docking grooves and mounting grooves are correspondingly fitted. This arrangement allows for the installation of two sealing rings, and the two coaxial sealing rings provide a double sealing effect, preventing liquid from flowing out of the conduit.
[0007] Preferably, a rubber layer is provided on the facing surfaces of the first connecting pipe and the second connecting pipe. The elasticity of the rubber layer allows for a tighter connection between the first and second connecting pipes, preventing liquid leakage from the joint.
[0008] Preferably, a blind hole is provided on the inner side of the insertion hole, and the fixing component is fixed inside the blind hole. The fixing component includes a spring fixedly connected to the bottom of the blind hole, and a fixing head is fixedly connected to the outer end of the spring. The fixing head corresponds to and cooperates with the fixing hole. As a preferred embodiment, the ends of the fixing hole and the fixing head are both hemispherical structures. In use, the insertion post is inserted into the insertion hole, and the insertion post squeezes the fixing head and overcomes the elastic force of the spring, so that the fixing head is completely retracted into the blind hole, allowing the insertion post to be smoothly inserted into the insertion hole. At this time, the fixing hole and the blind hole are coaxial, and the fixing head loses the squeezing force of the insertion post. The spring pushes the fixing head into the fixing hole, and the insertion and cooperation of the fixing head and the fixing hole limit and fix the insertion post, so that the first connecting tube and the second connecting tube are connected together.
[0009] Preferably, there are four connecting blocks, and the connecting blocks are arc-shaped.
[0010] Preferably, the outer surface of the second connecting pipe is provided with a mounting bearing, and a connecting ring is fixedly mounted on the outer side of the mounting bearing. Four connecting sleeves are fixed to the outer side of the connecting ring, and each connecting sleeve has an arc-shaped retaining edge on its outer side that engages with the connecting block. With this configuration, during use, the mounting bearing drives the connecting ring to rotate, and the connecting ring uses the connecting ring to engage the connecting sleeve with the connecting block, thereby firmly connecting the first and second connecting pipes together.
[0011] Preferably, the opposite ends of the first connecting pipe and the second connecting pipe are provided with connecting rings for connecting to the concrete duct.
[0012] This utility model provides a quick-release concrete conduit, which has the following advantages:
[0013] 1. This utility model uses a bearing to drive the connecting ring to rotate, and the connecting ring is used to make the connecting sleeve lock onto the connecting block, thereby firmly connecting the first connecting pipe and the second connecting pipe together, so that the concrete pouring conduit can be quickly assembled and disassembled.
[0014] 2. This utility model can achieve double sealing by setting two sealing rings, which can prevent the liquid in the concrete pouring pipe from leaking out from the joint. Attached Figure Description

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 This utility model provides a technical solution: a quick-release concrete conduit, including a first connecting pipe 1 and a second connecting pipe 2 that correspond to each other. The facing surfaces of the first connecting pipe 1 and the second connecting pipe 2 are provided with coaxial mating grooves 3 and mounting grooves 4, and a rubber sealing ring 5 is installed in the mounting groove 4. The facing surfaces of the first connecting pipe 1 and the second connecting pipe 2 are also provided with corresponding insert pins 7 and insert holes 8. The side of the insert pin 7 is provided with a fixing hole 701. The inside of the insert hole 8 is provided with a fixing component 9 that corresponds to the fixing hole 701. The outer circular surfaces of the first connecting pipe 1 and the second connecting pipe 2 are provided with corresponding connecting blocks 10 and connecting sleeves 13.
[0025] In this embodiment, two docking grooves 3 and two mounting grooves 4 are provided, and the docking grooves 3 and the mounting grooves 4 are correspondingly matched. This arrangement allows for the installation of two sealing rings 5, and the two coaxial sealing rings 5 can achieve a double sealing effect, preventing liquid from flowing out of the conduit.
[0026] In this embodiment, a rubber layer 6 is provided on the facing surfaces of the first connecting pipe 1 and the second connecting pipe 2. The elasticity of the rubber layer 6 allows for a tighter connection between the first connecting pipe 1 and the second connecting pipe 2, preventing liquid leakage from the joint.
[0027] In this embodiment, a blind hole 15 is provided on the inner side of the insertion hole 8. The fixing component 9 is fixed inside the blind hole 15. The fixing component 9 includes a spring 901 fixedly connected to the bottom of the blind hole 15. A fixing head 902 is fixedly connected to the outer end of the spring 901. The fixing head 902 corresponds to and cooperates with the fixing hole 701. As a preferred embodiment, the ends of the fixing hole 701 and the fixing head 902 are both hemispherical structures. In use, the insertion post 7 is inserted into the insertion hole 8, and the insertion post 7 is used to press and fix it. The head 902 overcomes the elastic force of the spring 901, causing the fixing head 902 to retract completely into the blind hole 15, allowing the plug pin 7 to be smoothly inserted into the plug hole 8. At this time, the fixing hole 701 is coaxial with the blind hole 15, and the fixing head 902 loses the squeezing force of the plug pin 7. The spring 901 pushes the fixing head 902 into the fixing hole 701. The plug pin 7 is limited and fixed by the plug-in cooperation of the fixing head 902 and the fixing hole 701, so that the first connecting tube 1 and the second connecting tube 2 are connected together.
[0028] In this embodiment, there are four connecting blocks 10, and each connecting block 10 is arc-shaped. A mounting bearing 11 is provided on the outer surface of the second connecting pipe 2. A connecting ring 12 is fixedly mounted on the outer side of the mounting bearing 11. Four connecting sleeves 13 are fixed on the outer side of the connecting ring 12, and each connecting sleeve 13 has an arc-shaped locking edge on its outer side that engages with the connecting block 10. With this configuration, during use, the mounting bearing 11 drives the connecting ring 12 to rotate, and the connecting ring 12 causes the connecting sleeves 13 to engage with the connecting block 10, thereby firmly connecting the first connecting pipe 1 and the second connecting pipe 2 together.
[0029] In this embodiment, the opposite ends of the first connecting pipe 1 and the second connecting pipe 2 are provided with connecting rings 14 for connecting to the concrete conduit.
[0030] In use, the first connecting pipe 1 and the second connecting pipe 2 are connected to the ends of the two concrete pouring conduits respectively via the connecting ring 14. The connecting surfaces of the first connecting pipe 1 and the second connecting pipe 2 are joined together. The insertion post 7 is inserted into the insertion hole 8. The insertion post 7 presses against the fixing head 902 and overcomes the elastic force of the spring 901, causing the fixing head 902 to retract completely into the blind hole 15, allowing the insertion post 7 to be smoothly inserted into the insertion hole 8. At this time, the fixing hole 701 and the blind hole 15 are coaxial, and the fixing head 902 loses the pressing force of the insertion post 7. The spring 901 pushes the fixing head 902 into the fixing hole 701. The insertion and engagement of the fixing head 902 and the fixing hole 701 limit and fix the insertion post 7, connecting the first connecting pipe 1 and the second connecting pipe 2 together. (During disassembly and assembly, pull the first connecting pipe in the opposite direction.) 1. The second connecting pipe 2 causes the inner arc wall of the fixing hole 701 to press the fixing head 902, overcoming the elastic force of the spring 901 again, so that the fixing head 902 is completely retracted into the blind hole 15, and the plug 7 is smoothly disengaged from the plug hole 8. At this time, the sealing ring 5 is tightly inserted into the docking groove 3. By setting two sealing rings 5, double sealing can be achieved to prevent the liquid in the concrete pouring pipe from leaking out from the joint. Then, the connecting ring 12 is rotated by the mounting bearing 11, and the connecting sleeve 13 is locked on the connecting block 10 by the connecting ring 12, so that the first connecting pipe 1 and the second connecting pipe 2 are firmly connected together (when disassembling and assembling, the connecting ring 12 is rotated again to separate the connecting sleeve 13 from the connecting block 10, so that the first connecting pipe 1 and the second connecting pipe 2 are separated), so that the concrete pouring pipe can be quickly disassembled and assembled.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
