Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically a hydraulically driven self-calibrating FRP pipeline docking and installation mechanism. Background Technology

[0002] With the development of composite material technology, fiber reinforced plastic (FRP) pipes have been widely used in chemical, water supply and drainage, and energy transmission fields due to their lightweight, high strength, corrosion resistance, and excellent insulation properties. The matching FRP pipe docking and installation mechanism, as a key device for achieving efficient and precise pipe connection, directly affects the quality and efficiency of engineering construction.

[0003] However, current FRP pipe connection and installation mechanisms still face significant technical bottlenecks. Due to the diverse specifications of FRP pipes, their diameters vary considerably, and existing installation mechanisms generally lack compatibility with different pipe sizes. In actual construction, when faced with changes in pipe diameter, frequent replacement or adjustment of core components such as specialized clamps, positioning devices, and drive assemblies is necessary. This is not only time-consuming and labor-intensive, increasing equipment debugging time, but also potentially causing component wear due to repeated disassembly and assembly, reducing equipment reliability. Furthermore, the complex adjustment process easily introduces human error, affecting pipe connection accuracy and thus reducing overall construction efficiency. This limits the versatility of installation mechanisms in multi-project, multi-specification pipeline engineering. Therefore, we propose a hydraulically driven self-calibrating FRP pipe connection and installation mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulically driven self-calibrating FRP pipe docking and installation mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulically driven self-calibrating FRP pipe docking and installation mechanism, comprising a U-shaped frame, a square groove formed on the surface of the U-shaped frame, and a fixing rod fixedly installed inside the square groove; a long groove formed on the top of the U-shaped frame, penetrating the U-shaped frame into the square groove; a socket block movably mounted on the surface of the fixing rod; a connecting plate fixedly mounted on the top of the socket block; and a cylinder fixedly mounted on the other end of the connecting plate; circular ring plates movably mounted on both sides of the cylinder; a fixing block one fixedly mounted on the side of the cylinder; a fixing block two fixedly mounted on the side of the circular ring plate; and a... Fixed block three, fixed block four is fixedly installed on the side of the annular plate, movable rods are movably installed inside fixed block one and fixed block two, movable rods are movably installed inside fixed block three and fixed block four, and there are two sets of fixed blocks one and two, and fixed blocks three and four are distributed in a cross pattern. A connecting rod is fixedly installed between the two sets of annular plates. A circular groove is opened on the surface of the connecting rod, and a connecting column is fixedly installed inside the circular groove. A circular sleeve plate is movably installed on the surface of the connecting column. An electric push rod is provided on the surface of the connecting plate, and the electric push rod is fixedly connected to the circular sleeve plate. A hydraulic device one is fixedly installed on the inner wall of the square groove, and the hydraulic device one is fixedly connected to the sleeve block.

[0006] As a further embodiment of this utility model: a damping rod is fixedly installed at the bottom of the U-shaped frame, and a circular plate is fixedly installed at the bottom of the damping rod. A spring is wound between the U-shaped frame and the circular plate, and a caster wheel is provided at the bottom of the circular plate.

[0007] As a further embodiment of this utility model, an arc groove is provided at the bottom of the inner part of the U-shaped frame.

[0008] As a further embodiment of this utility model: a side plate is fixedly installed on the side of the U-shaped frame, and a hydraulic device II is fixedly installed at the bottom of the side plate, and a lower pressure plate is fixedly installed at the bottom of the hydraulic device II.

[0009] As a further embodiment of this utility model: a reinforcing rib is fixedly installed at the connection between the U-shaped frame and the side plate, and the reinforcing rib is triangular in shape.

[0010] As a further embodiment of this utility model: the surface of the cylinder is provided with a groove, and the inner wall of the annular plate is provided with a protrusion, and the protrusion is located inside the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. This utility model involves placing the pipe inside the cylinder, activating the electric push rod, and using the power of the electric push rod to move the connecting rod downwards, causing the two sets of annular plates to rotate. The rotation of the annular plates gradually reduces the distance between the two sets of intersecting movable rods, thus limiting the pipe's position. Subsequently, the power of the hydraulic device pushes the sleeve block to interact with the surface of the fixed rod, causing the two sets of cylinders to gradually approach and the two sets of pipes to contact. Then, the operator connects the two sets of pipes. This device can adapt to pipes of different diameters, significantly improving its versatility and compatibility, thereby reducing the need for multiple devices due to different pipe specifications, lowering equipment procurement and management costs, and improving the consistency of connection quality, reducing connection deviations or quality problems caused by equipment differences, and enhancing quality control.

[0013] 2. This utility model, through the combined use of damping rods and springs, can reduce the impact force when moving the U-shaped frame, thereby avoiding mechanical damage to the FRP pipes and docking mechanisms, thus protecting the equipment and pipes. At the same time, it can reduce docking deviations caused by vibration or impact, ensure the accuracy of pipe docking, and improve installation precision.

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 -Appendix Figure 5 This utility model provides a hydraulically driven self-calibrating FRP pipe docking and installation mechanism, including a U-shaped frame 1. A square groove 2 is formed on the surface of the U-shaped frame 1, and a fixing rod 3 is fixedly installed inside the square groove 2. A long groove 4 is formed on the top of the U-shaped frame 1, penetrating the U-shaped frame 1 into the square groove 2. A sleeve block 5 is movably installed on the surface of the fixing rod 3. A connecting plate 6 is fixedly installed on the top of the sleeve block 5, and a cylinder 8 is fixedly installed at the other end of the connecting plate 6. Circular ring plates 9 are movably installed on both sides of the cylinder 8. A fixing block 1 10 is fixedly installed on the side of the cylinder 8, a fixing block 2 11 is fixedly installed on the side of the circular ring plate 9, and a fixing block 3 12 is fixedly installed on the side of the circular ring plate 9. Movable rods 14 are movably installed inside fixed block 4 13, fixed block 10 and fixed block 2 11, and fixed block 3 12 and fixed block 4 13. There are two sets of fixed blocks 10, 21 and 32 and 4 13, which are distributed in a cross pattern. A connecting rod 15 is fixedly installed between the two sets of annular plates 9. A circular groove 16 is opened on the surface of the connecting rod 15, and a connecting column 17 is fixedly installed inside the circular groove 16. An annular sleeve plate 18 is movably installed on the surface of the connecting column 17. An electric push rod 19 is provided on the surface of the connecting plate 6, and the electric push rod 19 is fixedly connected to the annular sleeve plate 18. A hydraulic device 7 is fixedly installed on the inner wall of the square groove 2, and the hydraulic device 7 is fixedly connected to the sleeve block 5.

[0024] The above solution allows the device to adapt to pipes of different diameters, significantly improving its versatility and compatibility. This reduces the need for multiple devices due to different pipe specifications, lowers equipment procurement and management costs, and helps improve the consistency of connection quality, reducing connection deviations or quality problems caused by equipment differences, thus enhancing quality control.

[0025] like Figure 2 As shown, a damping rod 20 is fixedly installed at the bottom of the U-shaped frame 1, and a circular plate 21 is fixedly installed at the bottom of the damping rod 20. A spring 22 is wound between the U-shaped frame 1 and the circular plate 21, and a caster wheel 23 is provided at the bottom of the circular plate 21.

[0026] The above solution, through the combined use of damping rod 20 and spring 22, can reduce the impact force when moving the U-shaped frame 1, thereby avoiding mechanical damage to the FRP pipe and the docking mechanism, thus protecting the equipment and pipes. At the same time, it can reduce docking deviation caused by vibration or impact, ensure the accuracy of pipe docking, and improve installation precision.

[0027] like Figure 1 As shown, an arc groove 28 is provided at the bottom of the interior of the U-shaped frame 1;

[0028] The above solution involves creating an arc groove 28 at the bottom of the U-shaped frame 1 to accommodate the connected pipes, thereby improving work efficiency.

[0029] like Figure 1 As shown, a side plate 24 is fixedly installed on the side of the U-shaped frame 1, and a hydraulic device 25 is fixedly installed at the bottom of the side plate 24. A lower pressure plate 26 is fixedly installed at the bottom of the hydraulic device 25.

[0030] The above solution involves fixing a side plate 24 to the side of the U-shaped frame 1, and fixing a hydraulic device 25 to the bottom of the side plate 24. A lower pressure plate 26 is fixedly installed at the bottom of the hydraulic device 25. When the device is in use, the DC or AC motor inside the hydraulic device 25 generates rotational power. The speed is reduced and the torque is increased by the gear reduction mechanism. The power is then transmitted to the lead screw or rack through gear transmission to push the lower pressure plate 26 to press against the ground, thereby supporting the device and ensuring the stability of the device during operation.

[0031] like Figure 1 As shown, a reinforcing rib 27 is fixedly installed at the connection between the U-shaped frame 1 and the side plate 24. The reinforcing rib 27 is triangular in shape.

[0032] The above solution is adopted: by fixing a reinforcing rib 27 at the connection between the U-shaped frame 1 and the side plate 24, the connection between the U-shaped frame 1 and the side plate 24 is improved, and the reinforcing rib 27 is triangular, which has stability.

[0033] like Figure 1 As shown, the surface of the cylinder 8 is provided with a groove, and the inner wall of the annular plate 9 is provided with a protrusion, and the protrusion is located inside the groove;

[0034] The above solution is adopted: by opening a groove on the surface of the cylinder 8 and setting a protrusion on the inner wall of the annular plate 9, with the protrusion located inside the groove, the annular plate 9 is made more stable when rotating on the surface of the cylinder 8.

[0035] A laser rangefinder is added to the inner side of the annular plate 9, and the sensor is connected to the controller. The controller adjusts the difference in the propulsion speed of the two sets of hydraulic devices in real time so that the pipe end faces are in parallel contact.

[0036] Working principle:

[0037] When FRP pipes need to be assembled, the workers place the two pipe sections inside the two sets of cylinders 8 respectively. Then, the workers activate the electric push rod 19 through an external switch. The contraction force generated by the electric push rod 19 causes the connecting rod 15 to move downward through the sleeve of the annular plate 18. This causes the two sets of annular plates 9 to rotate on the surface of the cylinder 8. As a result, the two sets of movable rods 14 gradually reduce the distance between them under the influence of the two sets of fixed blocks 10, 11, 12, and 13, which are distributed in a cross pattern. This limits the pipes. Then, the power of the hydraulic device 7 pushes the sleeve block 5 to slide on the surface of the fixed rod 3, causing the two sets of cylinders 8 to gradually approach each other and the two sets of pipes to contact. The workers then assemble and install the pipes.

[0038] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on.
