Description

Technical Field

[0001] This utility model relates to the field of pipe sheet metal supports, specifically to a pipe moving auxiliary device that can quickly adapt to different pipe diameters. Background Technology

[0002] During pipeline construction, maintenance, and transportation, support or clamping devices that cover the outer wall of pipes of different diameters are typically needed to fix, move, or assist in positioning them. Existing pipeline auxiliary devices mostly use fixed-size ring supports or require manual replacement of support rings to adapt to different pipe diameters. This method is cumbersome to adjust and inefficient. In addition, some adjustable devices use telescopic rods or threaded rings for diameter adjustment, but because the movements of the various adjusting rods are not synchronized, the overall ring structure is prone to deformation or eccentricity during adjustment, affecting the stability of the fit with the pipe. Utility Model Content

[0003] One objective of this invention is to provide a pipe moving auxiliary device that can quickly adapt to different pipe diameters, so as to solve the problem that the adjustment of existing pipe auxiliary devices is complicated and prone to eccentric deformation when adapting to different pipe diameters.

[0004] Specifically, this utility model discloses a pipe moving auxiliary device for rapid pipe diameter adaptation, including a first locking ring, a second locking ring, and rods. Both the first and second locking rings include multiple scissor rods that are sequentially hinged end to end and form a closed ring structure. Adjacent scissor rods are hinged together by a pair of hinge members. In the first locking ring, one of the multiple pairs of hinge members is slidably connected to the rod, and the other is fixedly connected to the rod. In the second locking ring, one of the multiple pairs of hinge members is slidably connected to the rod, and the other is fixedly connected to the rod.

[0005] Furthermore, the hinge connecting the first locking ring to the rod is a first sleeve, and the hinge connecting the second locking ring to the rod is a second sleeve. The first sleeve and the second sleeve are connected to slide synchronously.

[0006] Furthermore, both the first locking ring and the second locking ring include at least three scissor links.

[0007] Furthermore, each of the scissor links has a rubber pad on its inner side.

[0008] Furthermore, both the first locking ring and the second locking ring include a scissor link, and the top view of the first locking ring and the second locking ring is hexagonal.

[0009] Furthermore, the scissor link includes two intersecting rods, which are hinged at their intersection.

[0010] Furthermore, the hinge includes a first arm and a second arm connected together, with the first arm and the second arm forming a first predetermined angle.

[0011] Furthermore, the first set angle is the supplementary angle of the exterior angle obtained by dividing the circumferential angle by the number of scissor links.

[0012] Furthermore, both the first and second arms of the hinge are provided with grooves, and pins are provided in the grooves.

[0013] Furthermore, the geometric center lines of the first arm and the second arm define a first plane, the groove penetrates two opposite surfaces of the first arm and the second arm along a direction perpendicular to the first plane, and the two ends of the pin are respectively connected to the inner wall of the groove.

[0014] In this invention, by setting a first locking ring, a second locking ring, and a rod, and making both sets of locking rings form a closed ring structure by multiple scissor rods with hinged ends, the device can expand and contract radially synchronously when the sliding hinge point moves, thereby quickly adapting to pipes of different diameters and improving the applicability and assembly efficiency of the device.

[0015] In this invention, by defining the sliding hinges of the first locking ring and the second locking ring as the first and second connecting parts respectively, and connecting them to slide synchronously, the synchronous extension and retraction of the upper and lower scissor linkage mechanisms during the adjustment process can be realized, ensuring that the roundness of the ring structure is consistent when it expands or contracts, and preventing eccentricity or deformation.

[0016] In this invention, by providing a rubber pad on the inner side of each scissor linkage, elastic buffering and friction can be provided when the pipes come into contact, preventing scratches on the pipe surface caused by metal-to-metal contact, while also improving the clamping stability of the pipes.

[0028] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art should be able to understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Please refer to Figures 1-6This utility model discloses a pipe moving auxiliary device for rapid pipe diameter adaptation, including a first locking ring 1, a second locking ring 2, and a rod 8. Both the first locking ring 1 and the second locking ring 2 include multiple scissor rods that are sequentially hinged to form a closed ring structure. Adjacent scissor rods are hinged to each other by a pair of hinge members 3. In the first locking ring 1, one of the multiple pairs of hinge members 3 is slidably connected to the rod 8, and the other is fixedly connected to the rod 8. In the second locking ring 2, one of the multiple pairs of hinge members 3 is slidably connected to the rod 8, and the other is fixedly connected to the rod 8. The multiple scissor rods are sequentially connected to form a closed ring structure, so that the entire mechanism forms a complete circular or polygonal shape in the top view, which is used to cover the outer periphery of the pipe and achieve stable support.

[0030] According to one embodiment of this utility model, adjacent scissor links are hinged together by a pair of hinge members 3. The scissor link includes two members, a first member 4 and a second member 6. The first member 4 has a first pin hole in the middle, and the second member 6 also has a second pin hole in the middle. The first and second pin holes are coaxial, and a pin 33 is inserted into the first and second pin holes to form a scissor link. The two ends of the first member 4 and the second member 6 are also provided with pin holes for connection. It is understood that the connection between any two adjacent scissor links is hinged, wherein the first member 4 of one scissor link is hinged to the second member 6 of another scissor link, and so on.

[0031] According to one embodiment of this utility model, each pair of hinge members 3 connects two adjacent scissor rods to form a relatively rotatable hinge pair, allowing the first locking ring 1 and the second locking ring 2 to extend and retract in the radial direction. In the first locking ring 1, one of the multiple pairs of hinge members 3 is slidably connected to the rod body 8, while the other is fixedly connected to the rod body 8. With this structural design, when the sliding hinge member 3 moves along the direction of the rod body 8, the entire scissor linkage mechanism will simultaneously expand or contract around the rod body 8, thereby changing the inner diameter of the first locking ring 1 and the second locking ring 2. It can be understood that the structure of the second locking ring 2 is basically the same as that of the first locking ring 1, also including multiple scissor rods that are sequentially hinged end-to-end and interconnected hinge members 3. In the second locking ring 2, one of the multiple pairs of hinge members 3 is also slidably connected to the rod body 8, while the other is fixedly connected to the rod body 8. By setting such a sliding and fixed fit, the second locking ring 2 can also generate a telescopic movement synchronously when the sliding hinge 3 moves, thereby achieving a rapid adaptation to the outer diameter of the pipe together with the first locking ring 1.

[0032] According to one embodiment of this utility model, to ensure the synchronization of the two sets of locking rings, in a preferred embodiment, the sliding hinge 3 of the first locking ring 1 is defined as the first sleeve, and the sliding hinge 3 of the second locking ring 2 is defined as the second sleeve. Both are connected to the synchronizing rod 7 for synchronous sliding. Through this linkage design, when the operator pushes or drives only the sliding hinge 3 of one set of locking rings, the sliding hinge 3 of the other set of locking rings can move simultaneously at the same speed and direction, thereby ensuring that the upper and lower layers of locking rings maintain consistent geometry during adjustment and avoiding tilting or deformation of the rings due to asynchronous movement.

[0033] According to one embodiment of this utility model, taking the first socket as an example, the first socket includes two types: a first type of socket and a second type of socket. Since this utility model uses an X-shaped scissor linkage, the closed ring structure formed by the sequential connection of the first and second ends of this scissor linkage, namely the first locking ring and the second locking ring 2, please refer to... Figure 6 The side view of the pipe movement auxiliary device for quick adaptation of pipe diameter shows that the locking ring is actually composed of an inner layer of connecting rods and an outer layer of connecting rods. This is because the scissor connecting rod itself has a certain thickness. When connecting the scissor connecting rods, the connecting rods in the outer layer are hinged to each other, and the connecting rods in the inner layer are hinged to each other, thus forming an inner ring and an outer ring. In order to adapt to this structure, the outer ring and the rod body 8 adopt a first type of first sleeve, including a first type of sleeve 901 and a first hinge part 902 connected to the sleeve. The first hinge part 902 has the same structure as the hinge part 3 mentioned above. The inner ring and the rod body 8 adopt a second type of first sleeve, including a second type of sleeve 101, a connecting part 102 and a second hinge part 103. The second hinge part 103 and the sleeve are connected through the connecting part 102, thereby adapting to the inner ring. The second hinge part 103 is the same as the hinge part 3 mentioned above. It is understandable that the first type of sleeve 901 and the second type of sleeve 101 have the same inner diameter.

[0034] According to one embodiment of this utility model, both the first locking ring 1 and the second locking ring 2 include at least three scissor links to form a stable polygonal annular structure. Preferably, both sets of locking rings employ six scissor links, and the annular structure is hexagonally distributed when viewed from above. The six links form six symmetrical fulcrums in the annular direction, making the annular support structure more uniformly stressed, ensuring both uniform fit to pipes of different diameters and maintaining overall structural stability during adjustment.

[0035] According to one embodiment of this utility model, each scissor link consists of two intersecting rods, which are referred to as the first rod 4 and the second rod 6 for ease of description. The first rod 4 has a shaft hole in the middle, and the second rod 6 also has a shaft hole in the middle. The shaft holes of the first rod 4 are coaxial. The intersection of the first rod 4 and the second rod 6 is the overlapping point of their respective shaft holes, where a pin is used to hinge them together to form an intermediate hinge point 5, thus forming a typical X-shaped telescopic structure. Through the ring structure formed by the end-to-end hinge of multiple sets of X-shaped scissor links, the rods move synchronously during adjustment, resulting in smooth inner diameter changes and good roundness retention.

[0036] According to one embodiment of this utility model, to improve the fit stability between the device and the pipe, a rubber pad is installed on the inner side of each scissor linkage. This rubber pad provides a certain degree of elastic cushioning when in contact with the outer wall of the pipe, reducing the hard contact between the metal parts and the pipe, and preventing scratches or wear. Simultaneously, the friction of the rubber pad prevents the pipe from slipping during support or movement, enhancing the fixing effect.

[0037] According to one embodiment of the present invention, the hinge member 3 includes a first arm 31 and a second arm 32 connected together, arranged at a predetermined angle. This angle is determined based on the geometry of the locking ring to ensure that the scissor links accurately align and form a closed curve during ring splicing. In one specific embodiment, the predetermined angle can be the supplementary angle of the exterior angle obtained by dividing the circumferential angle by the number of scissor links, ensuring a uniform angle distribution among the multiple scissor links after ring connection, avoiding gaps or stress concentration. In this embodiment, the angle between the first arm 31 and the second arm 32 of the hinge member 3 is 120 degrees.

[0038] To further improve the reliability and durability of the hinge connection, grooves are provided on both the first arm 31 and the second arm 32 of the hinge member 3. A first groove 311 is formed on the first arm 31, and a second groove 321 is formed on the second arm 32. A pin 33 is installed inside each groove. The pin 33 connects two adjacent rods and allows them to rotate around the pin 33. The grooves accommodate the movement space of the pin 33 and provide guidance to a certain extent. Preferably, the grooves extend through the hinge in a direction perpendicular to the plane of the arm, with both ends connected to the inner wall of the groove. This makes the pin 33 more evenly stressed during rotation, reducing localized wear and extending the service life of the mechanism.

[0039] During use, the operator can manually or mechanically drive the sliding hinge 3 of any locking ring to move axially along the rod 8. When the sliding hinge 3 moves, due to the geometric constraints between the scissor links, the entire ring mechanism will synchronously contract or expand, causing the inner diameter of the locking ring to change accordingly. The upper and lower sets of locking rings are linked through the rod 8, thus maintaining synchronous changes. When a larger diameter pipe needs to be fitted, simply push the sliding hinge 3 outward; when a smaller diameter pipe needs to be clamped, push the sliding hinge 3 inward to quickly achieve adjustment. The entire adjustment process requires no parts replacement and does not rely on complex drive devices; the structure is compact and the operation is simple. Furthermore, this device can be equipped with positioning pins, limit sleeves, or fine-tuning mechanisms on the rod 8 according to actual needs to control the maximum stroke of the sliding hinge 3 and prevent overextension leading to instability. In some embodiments, the rod 8 can be mounted on a movable frame via support seats at both ends, with a roller assembly at the bottom of the movable frame, thereby enabling the movement of the entire device. By adjusting the opening and closing angle of the locking ring, the operator can complete the loading, unloading, positioning and handling of pipelines at different positions.

[0040] In summary, this utility model achieves rapid adjustment of the pipe clamping ring by setting two sets of scissor-type locking rings on both sides of the rod body 8 and forming a synchronous telescopic mechanism through a combination of sliding and fixed connections. This structure not only solves the problems of cumbersome adjustment and low fitting accuracy of traditional pipe support devices, but also improves operational convenience and safety, and has good promotional value and application prospects.

[0041] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
