Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, and more specifically to a pipeline connection structure for water conservancy projects. Background Art

[0002] In the field of water conservancy projects, concrete cement pipes are a commonly used water supply pipeline. Their connection and assembly methods have long relied on cranes and manual operations, and the joints need to be sealed with cement putty after connection. This traditional method has many drawbacks and disadvantages, which seriously affects the efficiency, quality and cost control of the project.

[0003] First of all, from the perspective of construction efficiency, the connection method of crane and manual cooperation requires a lot of time and manpower. At the construction site, the operation of the crane requires professional personnel to direct and dispatch, and when manual work is done on the pipes, it is very difficult to accurately locate and adjust the position of the concrete cement pipes due to their heavy weight and clumsy size. Repeated attempts are often required to complete the initial docking. This process is not only cumbersome to operate, but also extremely susceptible to interference from factors such as weather and site conditions. Once unfavorable factors occur, the construction progress will be seriously affected, resulting in an extension of the entire water conservancy project construction period, increasing the time cost and indirect costs of the project.

[0004] Secondly, there are significant defects in the connection quality. It is difficult to ensure the sealing and concentricity of the pipe connection by manual docking. Due to the inaccuracy of manual operation, there may be uneven gap sizes at the pipe interface. Even if cement putty is subsequently encapsulated, it is difficult to completely make up for these initial connection defects. With the passage of time and the long-term scouring and pressure of water flow, these uneven gaps are prone to become leakage points, resulting in waste of water resources and may even cause safety hazards such as foundation settlement, seriously affecting the long-term stable operation of water conservancy projects. In view of this, we propose a pipe connection structure for water conservancy projects. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention improves the existing connection structure of concrete pipes by arranging a rolling arc load mechanism on the pipe support, providing a sliding support on the top of the pipe support, and driving the hoisting shell group to slide on the sliding support through a reciprocating screw mechanism. The hoisting shell group drives the pipe stabilizing mechanism to move the pipe, and the mobile pipe is connected and assembled through the cooperation of the mode switching mechanism and the pipe stabilizing mechanism. Compared with the traditional crane and manual cooperation method, the time and difficulty of manual repeated adjustment of the pipe position are greatly reduced, the transportation and docking of the pipe are more accurate and efficient, and the influence of external environmental factors is also less, which can significantly speed up the construction progress, shorten the construction period of water conservancy projects, and reduce time costs and indirect costs.

[0020] 2. The present invention drives the central axis rod through a mode switching mechanism, and the central axis rod drives the driving rod. The opposite wire grooves on the driving rod rotate to move the moving assembly, causing the connecting rod assembly and the inner support assembly to shrink or expand in an annular shape, so as to adapt to the inner wall of the concrete pipe and achieve a stable effect; according to the actual size of the inner wall of the concrete pipe, the mode switching mechanism can be used to drive the relevant components to operate, so that the connecting rod assembly and the inner support assembly can be flexibly adapted to concrete pipes of different diameters, thereby improving the applicability of the invention in various specifications of pipe connection scenarios. After adapting to the inner wall of the pipe, a stable supporting effect can also be achieved, ensuring that the pipe remains stable during movement, docking and assembly, effectively avoiding connection deviation problems caused by unstable factors such as shaking and offset, and helping to improve the accuracy and quality of pipe connection.

[0021] 3. The mode switching mechanism of the present invention drives the outer sleeve to rotate, and the outer sleeve drives the four fixed rods to rotate. The fixed rod drives the central axis rod, the driving rod, the moving assembly, the connecting rod assembly and the inner support assembly to rotate synchronously as a whole. When the inner support assembly is fixed on the inner wall of the pipeline, it drives the pipeline to rotate as a whole, so as to achieve the effect of cement puttying and sealing the pipeline joints in one position. By rotating the pipeline in a fixed position, the construction personnel do not need to move around the pipeline or frequently adjust their own positions to perform cement puttying and sealing. The operation is more convenient and efficient, reducing the physical consumption and construction time of the construction personnel, and also reducing the problem of inconsistent packaging quality caused by the frequent movement of the construction personnel. Carrying out cement puttying and sealing in a stable position can better control the thickness, uniformity and flatness of the cement coating, avoid packaging defects caused by changes in the pipeline position, such as cracks, unevenness or poor sealing, thereby improving the packaging quality of the pipeline joints, enhancing the sealing and durability of the pipeline, reducing the probability of later leakage and other problems, and ensuring the long-term stable operation of the water conservancy project.

[0022] 4. When the concrete pipe in the present invention is being assembled and loaded or unloaded after assembly, horizontal movement is achieved through a number of rotating balls on the load-bearing arc plate. When the concrete pipe needs to be rotated, the balls and rollers assist in the rotation, thereby reducing the bearing pressure of the pipe stabilizing mechanism, prolonging its service life and saving energy and reducing emissions.

[0023] 5. The present invention realizes the function of adjusting the size of the annular inner support and the overall rotation through a driving structure, which has the beneficial effects of saving space and cost, simplifying the equipment structure and control system, improving operational convenience, and improving the adaptability and versatility of the equipment.

[0049] like Figures 1 to 13 As shown, the present invention relates to a pipe connection structure for water conservancy projects, comprising a pipe support 1, on which a plurality of rolling arc load mechanisms 2 are linearly and evenly spaced, a sliding support 3 is provided at the top of the pipe support 1, on which a reciprocating screw mechanism 4 is provided, a lifting shell group 5 is hoisted at the moving end of the reciprocating screw mechanism 4, one end of the lifting shell group 5 is connected to a pipe stabilizing mechanism 6, and the other end of the lifting shell group 5 is connected to a mode switching mechanism 7, and the pipe stabilizing mechanism 6 is fixedly connected to the mode switching mechanism 7;

[0050] The pipeline stabilizing mechanism 6 includes an inner diameter adjusting component 601, a full-rotation component 602, a moving component 603, a connecting rod component 604 and an inner support component 605. The inner diameter adjusting component 601 is connected to the end of the mode switching mechanism 7 away from the lifting shell group 5, the full-rotation component 602 is connected to the end of the mode switching mechanism 7 away from the lifting shell group 5, the full-rotation component 602 is rotatably sleeved on the inner diameter adjusting component 601, the moving component 603 is slidably sleeved on the full-rotation component 602 in a circular shape with equal intervals and is connected to the inner diameter adjusting component 601, the connecting rod component 604 is hingedly connected to the moving component 603, and the inner support component 605 is hingedly connected to the end of the connecting rod component 604 away from the moving component 603.

[0051] The present invention improves the existing connection structure of concrete pipes by arranging a rolling arc load mechanism 2 on a pipe support 1, providing a sliding support 3 on the top of the pipe support 1, and driving a hoisting shell group 5 to slide on the sliding support 3 through a reciprocating screw mechanism 4. The hoisting shell group 5 drives a pipe stabilizing mechanism 6 to move the pipe, and the mobile pipe is connected and assembled through the cooperation of a mode switching mechanism 7 and the pipe stabilizing mechanism 6. Compared with the traditional crane and manual cooperation method, the time and difficulty of manual repeated adjustment of the pipe position are greatly reduced, and the transportation and docking of the pipe are more accurate and efficient, and are less affected by external environmental factors. The construction progress can be significantly accelerated, the construction period of the water conservancy project can be shortened, and the time cost and indirect cost can be reduced.

[0052] In an embodiment of the present invention, the inner diameter adjustment assembly 601 includes a central axis rod 6011, a driving rod 6012 and a corresponding wire groove 6013. The central axis rod 6011 is fixedly connected to the end of the mode switching mechanism 7 away from the lifting shell group 5, the driving rod 6012 is connected to the end of the central axis rod 6011 away from the mode switching mechanism 7, and the corresponding wire groove 6013 is opened at the end of the driving rod 6012 away from the central axis rod 6011.

[0053] In an embodiment of the present invention, the full-rotation assembly 602 includes an outer sleeve 6021 and a fixed rod 6022. The outer sleeve 6021 is connected to the end of the mode switching mechanism 7 away from the lifting shell group 5. The outer sleeve 6021 is rotatably sleeved on the central axis rod 6011. The fixed rod 6022 is fixedly connected to the end of the outer sleeve 6021 away from the mode switching mechanism 7 in a circular shape with equal intervals. The movable assembly 603 is slidably sleeved on the fixed rod 6022 and is cooperatively connected to the opposite wire groove 6013.

[0054] The present invention drives the central axis rod 6011 through the mode switching mechanism 7, and the central axis rod 6011 drives the driving rod 6012. The opposite wire grooves 6013 on the driving rod 6012 rotate to move the moving component 603, causing the connecting rod component 604 and the inner support component 605 to shrink or expand in an annular shape, so as to adapt to the inner wall of the concrete pipe and achieve a stable effect; according to the actual size of the inner wall of the concrete pipe, the mode switching mechanism 7 can be used to drive the relevant components to operate, so that the connecting rod component 604 and the inner support component 605 can be flexibly adapted to concrete pipes of different diameters, thereby improving the applicability of the invention in various specifications of pipe connection scenarios. After adapting to the inner wall of the pipe, a stable supporting effect can also be achieved, ensuring that the pipe remains stable during movement, docking and assembly, effectively avoiding connection deviation problems caused by unstable factors such as shaking and offset, and helping to improve the accuracy and quality of pipe connection.

[0055] If the mode switching mechanism 7 drives the outer sleeve 6021 to rotate, the outer sleeve 6021 drives the four fixed rods 6022 to rotate, and the fixed rod 6022 drives the central axis rod 6011, the driving rod 6012, the moving assembly 603, the connecting rod assembly 604 and the inner support assembly 605 to rotate synchronously as a whole. When the inner support assembly 605 is opened and fixed on the inner wall of the pipe, it drives the pipe to rotate as a whole, so as to achieve the effect of rotating the connected pipe to achieve the cement putty sealing effect at the pipe joint in one position. By rotating the pipe at a fixed position, the construction personnel do not need to move around the pipe or frequently adjust their own position to perform cement putty sealing. The operation is more convenient and efficient, which reduces the physical exertion and construction time of the construction personnel, and also reduces the problem of inconsistent sealing quality caused by frequent movement of the construction personnel. Carrying out cement puttying in a stable position can better control the thickness, uniformity and flatness of the cement coating, and avoid packaging defects caused by changes in the pipeline position, such as cracks, unevenness or poor sealing. This will improve the packaging quality of the pipeline joints, enhance the sealing and durability of the pipeline, reduce the probability of later leakage and other problems, and ensure the long-term stable operation of water conservancy projects.

The moving collar 6031 in the present invention is symmetrically arranged in two groups, and each moving collar 6031 is provided with four sliding holes 6033 and hinge grooves A6034.

[0057] In an embodiment of the present invention, the connecting rod assembly 604 includes a rotating block A6041, a rotating block B6042 and a reinforcing block 6043, one end of the rotating block A6041 is hingedly connected to the hinge groove A6034, one end of the reinforcing block 6043 is fixedly connected to the end of the rotating block A6041 away from the hinge groove A6034, one end of the rotating block B6042 is fixedly connected to the end of the reinforcing block 6043 away from the rotating block A6041, and the other end of the rotating block B6042 is hingedly connected to the inner support assembly 605.

The inner arc block 6053 is fixedly connected to the end of the support column 6051 away from the hinge slot B6052.

[0059] In the present invention, when the mode switching mechanism 7 drives the central axis rod 6011 to rotate, the central axis rod 6011 drives the driving rod 6012, and the opposing wire grooves 6013 on the driving rod 6012 rotate so that the movable ring 6031 slidably mounted on the fixed rod 6022 cooperates with the inner thread groove 6032 and the opposing wire groove 6013, so that the two movable rings 6031 move in opposite directions. The opposite movement of the movable ring 6031 drives the two groups of rotating blocks A6041, the reinforcement block 6043 and the rotating block B6042 near one end of the hinge groove A6034 to move away from or approach. Since the rotating block B6042 near one end of the support column 6051 is hingedly connected to the hinge groove B6052, the support column 6051 and the inner arc block 6053 expand outward or contract inward, thereby achieving the effect of fitting the concrete pipe.

When the concrete pipe needs to rotate, the rolling balls 204 and the rollers 203 jointly assist in the rotation, thereby reducing the bearing pressure of the pipe stabilizing mechanism 6, prolonging the service life, and saving energy and reducing emissions.
