Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline guidance technology, and in particular to an open pipeline guidance device. Background Technology
[0002] Open-type pipeline guide devices are designed to guide pipelines to operate stably and prevent them from deviating or bending excessively. These devices are typically used in the transportation of liquids or gases to ensure proper installation and long-term stability of pipelines, thereby improving system safety and efficiency, including optimizing pipeline layout and meeting the requirements of different environmental pressures.
[0003] However, in actual use, the following shortcomings still exist. For example, existing open-type pipeline guiding devices cannot achieve safe pipeline follow-up, reduce stress and wear, improve system dynamic response and reliability. When the equipment moves, the pipeline is prone to hard friction and pulling with the device, resulting in wear and damage to the outer sheath. This not only increases the risk of faults such as cable short circuits and pipeline leaks, but also requires frequent pipeline replacement, increasing maintenance costs. At the same time, rigid connections cannot absorb movement deviations, which easily leads to stress concentration, causing cracks and deformation at the connection between the device and the pipeline, shortening the overall service life. In addition, the unsuitable structure will limit the flexibility of equipment movement, slow down the system's dynamic response speed, and make it difficult to meet the high-frequency and complex movement requirements of automated equipment. Frequent failures will reduce the stability of system operation, affect production continuity, and even cause safety accidents.
[0004] Therefore, this utility model proposes an open pipeline guiding device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an open-type pipeline guiding device.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an open pipeline guiding device, including a connecting block, and further comprising: The connecting block has a support frame and a guide plate. One side of the connecting block is fixedly connected to one end of the support frame, and the other end of the support frame is fixedly connected to the guide plate. The guide plate is mounted on one side of the connecting block via the support frame, forming an open channel for accommodating and guiding pipelines. The top of the connecting block has a cavity in the vertical direction. The cavity is a concave spherical cavity structure. The bottom of the connecting block has a solid sphere integrally formed. The shape of the solid sphere is adapted to the inner spherical structure of the cavity.
[0007] Furthermore, the solid ball at the bottom of the connecting block can be rotatably fitted into the cavity at the top of another connecting block.
[0008] The beneficial effects of adopting the above-mentioned further solution are: by the embedded cooperation between the solid ball at the bottom of the connecting block and the cavity at the top of another connecting block, a core ball pair connection is formed. The solid ball can rotate flexibly in the cavity, providing a multi-directional rotation basis for adjacent connecting blocks around the center of the ball. This allows multiple modules to be connected in series to adapt to the movement trajectory of the equipment, realize the overall flexible bending and angle adjustment of the drag chain, and provide flexible structural support for pipeline guidance.
[0009] Furthermore, a limiting protrusion is provided on the inner spherical wall of the cavity, and the limiting protrusion is an annular boss structure.
[0010] The beneficial effects of adopting the above-mentioned further solution are: the limiting protrusion of the cavity is a rigid constraint formed by extending circumferentially from the inner spherical wall. It is distributed in a ring around the center of the cavity, which can build an axial blocking structure in advance without affecting the radial embedding of the solid ball, thus providing a basic physical barrier to prevent the solid ball from detaching in the future.
[0011] Furthermore, the inner arc surface of the limiting protrusion smoothly transitions with the inner spherical surface of the cavity, which is used to axially limit the solid ball embedded in the cavity and prevent the solid ball from detaching from the cavity.
[0012] The beneficial effects of adopting the above-mentioned further solution are: the inner arc surface of the limiting protrusion and the spherical surface inside the cavity are smoothly transitioned, which can avoid stress concentration at the connection between the two. When the solid ball tends to axially detach from the cavity, the ring-shaped limiting protrusion will form a uniform contact with the surface of the solid ball, which will restrict the axial displacement of the solid ball through physical blocking, accurately achieve axial limiting, and effectively prevent it from detaching from the cavity.
[0013] Furthermore, an annular limiting groove is provided in the middle of the outer spherical surface of the solid sphere along the circumference, and the width of the limiting groove is adapted to the width of the limiting protrusion.
[0014] The beneficial effects of adopting the above-mentioned further solution are: the annular limiting groove in the middle of the outer spherical surface of the solid ball has a groove width that matches the width of the limiting protrusion. It is a complementary structure to match the limiting protrusion. The groove is opened along the circumference of the solid ball, which can provide precise accommodation space for the limiting protrusion when the solid ball is installed, ensuring that the two can be stably matched, while avoiding the limiting groove being too wide or too narrow and affecting subsequent functions.
[0015] Furthermore, the solid sphere is embedded in the cavity, the limiting protrusion is embedded in the limiting groove, and the two side groove walls of the limiting protrusion are in clearance fit with the inner wall of the limiting groove, so as to achieve axial limiting of the solid sphere without affecting the rotational freedom of the solid sphere around its own center.
[0016] The beneficial effects of adopting the above-mentioned further solution are: when the solid ball is installed, the limiting protrusion is embedded in the limiting groove. The gap between the two not only retains a small space for movement, but also realizes structural linkage. The gap can avoid rigid contact that hinders the rotation of the solid ball. While preventing the solid ball from detaching through the axial constraint of the protrusion and the groove wall, it does not affect the multi-directional rotation of the solid ball around its own center, thus taking into account both the limiting and flexible rotation requirements.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the device forms a ball joint connection between the concave spherical cavity at the top of the connecting block and the solid ball at the bottom of another connecting block, enabling multi-directional rotation and flexible adaptation of adjacent modules. When multiple modules are connected in series, the solid ball can rotate and micro-displace around the center of the ball within the cavity, absorbing motion deviations and manufacturing errors, reducing stress concentration. The guide plate is suspended on one side of the connecting block by a support frame, forming an open channel for accommodating and guiding cables or pipelines. It achieves safe and stable pipeline movement with the equipment, avoiding jamming and wear, improving the dynamic response and operational reliability of the system, and realizing safe pipeline movement, reducing stress and wear, and improving the dynamic response and reliability of the system.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1-4 As shown, this embodiment provides a technical solution: an open pipeline guiding device, including a connecting block 1, and further including: The support frame 2 and guide plate 3 are connected. One side of the connecting block 1 is fixedly connected to one end of the support frame 2, and the other end of the support frame 2 is fixedly connected to the guide plate 3. The guide plate 3 is located on one side of the connecting block 1 through the support frame 2, forming an open channel for accommodating and guiding pipelines. A cavity 4 is vertically formed on the top of the connecting block 1. The cavity 4 is a concave spherical cavity structure. A solid ball 6 is integrally formed on the bottom of the connecting block 1. The shape of the solid ball 6 is adapted to the inner spherical structure of the cavity 4. This device connects the concave spherical cavity on the top of the connecting block 1 with the solid ball 6 on the bottom of the other connecting block 1. Ball 6 forms a ball joint connection, enabling multi-directional rotation and flexible adaptation of adjacent modules. When multiple modules are connected in series, the solid ball 6 can rotate and micro-displace around the center of the ball within the cavity 4, absorbing motion deviations and manufacturing errors, and reducing stress concentration. The guide plate 3 is suspended on one side of the connecting block 1 through the support frame 2, forming an open channel for accommodating and guiding cables or pipelines. It achieves safe and stable pipeline movement with the equipment, avoiding jamming and wear, improving the dynamic response and operational reliability of the system, and realizing safe pipeline movement, reducing stress and wear, and improving the dynamic response and reliability of the system.
[0022] like Figures 1-4As shown, the solid ball 6 at the bottom of connecting block 1 is rotatably embedded in the cavity 4 at the top of another connecting block 1. Through the embedding and cooperation of the solid ball 6 at the bottom of connecting block 1 and the cavity 4 at the top of another connecting block 1, a core ball joint connection is formed. The solid ball 6 can rotate flexibly within the cavity 4, providing a multi-directional rotation basis for adjacent connecting blocks 1 around the center of the ball. This allows multiple modules to be connected in series to adapt to the movement trajectory of the equipment, achieving flexible bending and angle adjustment of the entire cable chain, and providing flexible structural support for pipeline guidance. A limiting protrusion 5 is provided on the inner spherical wall of the cavity 4. The limiting protrusion 5 is an annular boss structure. The limiting protrusion 5 of the cavity 4 is located from the inner spherical wall. The rigid constraint formed by the circumferential extension of the wall, which is distributed in a ring around the center of the cavity 4, can pre-construct an axial blocking structure without affecting the radial embedding of the solid ball 6, providing a basic physical barrier to prevent the solid ball 6 from detaching later. The inner arc surface of the limiting protrusion 5 smoothly transitions with the inner spherical surface of the cavity 4, which is used to axially limit the solid ball 6 embedded in the cavity 4 and prevent the solid ball 6 from detaching from the cavity 4. The smooth transition between the inner arc surface of the limiting protrusion 5 and the inner spherical surface of the cavity 4 can avoid stress concentration at the junction. When the solid ball 6 has a tendency to axially detach within the cavity 4, the ring-shaped limiting protrusion 5 will interact with the solid ball. The surfaces of the solid sphere 6 form a uniform contact, physically restricting the axial displacement of the solid sphere 6 and precisely limiting its axial position, effectively preventing it from detaching from the cavity 4. An annular limiting groove 7 is circumferentially formed in the middle of the outer spherical surface of the solid sphere 6. The width of the groove 7 matches the width of the limiting protrusion 5. This annular limiting groove 7 in the middle of the outer spherical surface of the solid sphere 6, with its opening width matching the width of the limiting protrusion 5, is a complementary structure to the limiting protrusion 5. This groove, circumferentially formed, provides precise accommodating space for the limiting protrusion 5 during the installation of the solid sphere 6, ensuring a stable fit between the two, while avoiding the influence of the limiting groove 7 being too wide or too narrow. In subsequent functions, the solid ball 6 is embedded in the cavity 4, and the limiting protrusion 5 is embedded in the limiting groove 7. The two side groove walls of the limiting protrusion 5 are in clearance fit with the inner wall of the limiting groove 7. While achieving axial limitation of the solid ball 6, it does not affect the rotational freedom of the solid ball 6 around its own center. When the solid ball 6 is embedded, the limiting protrusion 5 is embedded in the limiting groove 7. The clearance fit between the two retains a small amount of room for movement and achieves structural linkage. The clearance can avoid rigid contact that hinders the rotation of the solid ball 6. While preventing the solid ball 6 from detaching through the axial constraint of the protrusion and the groove wall, it does not affect the multi-directional rotation of the solid ball 6 around its own center, thus taking into account both the limitation and flexible rotation requirements.
[0023] Working principle: like Figures 1-4As shown, the concave spherical cavity at the top of connecting block 1 and the solid ball 6 at the bottom of another connecting block 1 form a spherical pair connection. The shape of the solid ball 6 is adapted to the spherical surface inside the cavity 4. After installation, it can rotate and micro-displace around the center of the ball at a small angle. When multiple modules are connected in series, this structure can absorb equipment movement deviations and manufacturing errors, reduce stress concentration, provide a basis for the overall flexible bending and angle adjustment of the cable chain, adapt to the equipment movement trajectory, and ensure structural flexibility. The annular limiting protrusion 5 on the inner spherical wall of the cavity 4 and the annular limiting groove 7 in the middle of the outer spherical surface of the solid ball 6 form a key fit. The limiting protrusion 5 is a rigid constraint, and the inner arc surface smoothly transitions to the inner spherical surface of the cavity 4. The groove opening of the limiting groove 7 is wide. The width of the protrusion is adapted to the height of the protrusion. During installation, the limiting protrusion 5 is embedded in the limiting groove 7, and the two are fitted with a gap. This not only prevents the solid ball 6 from detaching from the cavity 4 through the axial constraint of the protrusion and the groove wall, but also retains a small space for movement due to the gap, so as not to hinder the multi-directional rotation of the solid ball 6 around its own center. This balances the limiting stability and the degree of rotational freedom. At the same time, the guide plate 3 is fixed on one side of the connecting block 1 through the support frame 2 to form an open channel. This channel accommodates and guides cables or pipelines as the equipment moves, avoiding pipeline jamming and wear, realizing safe and stable pipeline follow-up, and ultimately improving the dynamic response and operational reliability of the system, achieving the dual functions of pipeline protection and structural flexibility.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
