Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tooling technology for pipeline engineering, and in particular relates to an inflatable pipeline conveying support device. Background Technology

[0002] In pipeline construction, pipeline support devices are crucial equipment for ensuring construction quality and efficiency, and their role and significance cannot be ignored. Firstly, pipeline support devices provide stable support, preventing bending, deformation, or displacement of pipelines due to gravity or external forces during installation or transportation, thus ensuring that the pipeline's geometry and functionality are not compromised. Secondly, support devices effectively reduce friction between the pipeline and the ground or other supporting components, lowering the risk of pipeline surface wear and damage, and extending the pipeline's service life. Furthermore, during pipeline splicing, welding, and commissioning, support devices provide a safe and reliable working platform, improving operational accuracy and construction efficiency.

[0003] Currently used pipe support devices have several shortcomings and deficiencies in practical applications. First, the contact between the rollers and the pipe is line contact. Due to the small contact area, the pressure on the pipe surface is concentrated, easily causing localized deformation, especially for softer or thinner pipes. This problem is particularly pronounced and can affect the pipe's shape integrity and conveying function. Second, the contact between the rollers and the pipe is hard, resulting in high friction. This easily causes wear on the pipe surface during transport, especially during prolonged use or high-frequency operation, significantly accelerating wear and reducing the pipe's lifespan. Furthermore, the rollers of the support devices typically employ a rigid, fixed design, lacking flexibility. During pipe operation, external forces or vibrations can easily cause instability, leading to swaying, slippage, or even support failure, further affecting the smoothness and safety of the conveying process. Simultaneously, these devices lack adaptability to different pipe diameters or construction environments, making adjustment and maintenance difficult and limiting their application range and efficiency. In summary, existing pipe support devices have significant room for improvement in terms of contact type, wear resistance, flexible design, and adaptability. Utility Model Content

[0004] In view of the problems of unreasonable contact form, serious friction damage, insufficient flexibility leading to unstable support, poor adaptability and difficult maintenance of existing pipeline support devices, this utility model provides an inflatable pipeline conveying support device.

[0005] This utility model is implemented as follows: an inflatable pipeline conveying support device includes a base, two idlers arranged in a V-shape, an inner support for the idlers, and an outer support for the idlers. The inner end of each idler is hinged to the inner support, and the outer end of each idler is hinged to the outer support. The inner and outer supports are mounted on the base. The idler is characterized in that: each idler includes a roller with its two ends respectively connected to the inner and outer supports, and at least one flexible roller mounted on the roller. The flexible roller includes a cylindrical inflatable roller body and a hub. The hub provides support for the inflatable roller body and is connected to the roller. The hub and the roller form a rotating pair.

[0006] In the above technical solution, preferably, one end of the roller is installed on the inner support or outer support of the idler roller via a quick-release pin, the roller is equipped with two locking bushings, and locking screws for locking the locking bushing relative to the axial position of the roller are installed on the locking bushings, and the flexible roller is clamped and fixed between the two locking bushings.

[0007] In the above technical solution, preferably, the roller hub includes a shaft hole and an annular sealing grooves provided at both ends of the roller hub, and the edge of the inflatable roller body is fitted into the annular sealing groove.

[0008] In the above technical solution, preferably, the outer support of the idler roller is fixed to the base, the inner support of the idler roller is installed on the base through a height-adjustable bracket assembly, a transverse guide rail is installed on the inner support of the idler roller, and two slider seats are mounted on the transverse guide rail, with the two slider seats respectively hinged to the inner end of the roller.

[0009] In the above technical solution, preferably, the height-adjustable bracket assembly includes a support frame and a support pin installed at the lower end of the support. The lower part of the inner support of the idler roller is hinged to the support frame by a pin shaft. The base has N pin holes evenly spaced. The support pin is inserted into one of the pin holes and causes the support frame to form a support for the inner support of the idler roller.

[0010] The inflatable pipeline support and conveying device proposed in this utility model solves all the problems of existing support devices by adopting flexible inflatable support rollers, and shows many advantages in performance and applicability.

[0011] First, the inflatable support roller uses flexible materials, forming a large contact area with the pipe surface, upgrading from line contact to surface contact. This significantly reduces the risk of excessive local stress on the pipe, effectively preventing pipe surface deformation and damage, making it particularly suitable for conveying flexible or thin-walled pipes. Second, the inflatable nature of the flexible roller gives it a certain buffering capacity, which can significantly reduce the friction between the pipe and the support device, reduce surface wear, thereby extending the service life of the pipe, and improving the smoothness and reliability of the conveying process.

[0012] Furthermore, the design of the inflatable support roller is identical to that of existing general-purpose inflatable wheels, allowing for a wide range of readily available materials. Existing wheel components and even discarded wheels can be directly used as raw materials, reducing production costs and offering significant economic and environmental value. Its flexible design enables the support device to absorb energy generated by vibration or impact during transport, improving support stability and reducing swaying or slippage caused by insufficient support rigidity, thus enhancing adaptability. Through modular design, the device is easy to disassemble and maintain, and the number and arrangement of the inflatable rollers can be flexibly adjusted to meet the transport requirements of different pipe diameters, materials, and construction environments.

[0013] In summary, this inflatable pipeline support and conveying device demonstrates significant advantages in protecting pipelines, extending service life, reducing costs, and improving operational stability and adaptability. It is an efficient, environmentally friendly, and economical pipeline support solution. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] To address the problems of existing pipeline support devices, such as unreasonable contact patterns, severe friction damage, insufficient flexibility leading to unstable support, poor adaptability, and difficult maintenance, this utility model provides an inflatable pipeline conveying support device. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0019] Example 1

[0020] Please see Figure 1An inflatable pipeline conveying support device includes a base 1, two V-shaped idler rollers 2, an inner idler roller support 3, and an outer idler roller support 4. The inner end of each idler roller is hinged to the inner idler roller support, and the outer end of each idler roller is hinged to the outer idler roller support. The inner and outer idler roller supports are mounted on the base. In this embodiment, the inner idler roller support is fixed to the base. The inner and outer idler roller supports are connected to the inner and outer ends of the idler rollers respectively via hinged structures, thereby realizing the rotation and support functions of the idler rollers. The base is used to fix and support the entire device, ensuring its stability. The V-shaped idler rollers, through the hinge of the inner and outer supports, enable the idler rollers to stably bear and guide the pipeline during pipeline conveying, playing a supporting and guiding role. This structural design allows the pipeline to move smoothly along the conveying path, while reducing friction and deformation, improving the safety and efficiency of the pipeline conveying process.

[0021] The idler roller includes a roller 2-1 with its two ends connected to an inner support and an outer support, respectively, and at least one flexible roller mounted on the roller. This design, by installing a flexible roller on the roller, effectively reduces friction between the pipe and the idler roller, minimizing damage to the pipe during transport, while simultaneously improving the adaptability and stability of the support device. The flexible roller, in its supported state, naturally forms a concave surface that better conforms to the outer wall of the pipe, thereby distributing stress, reducing localized pressure, further lowering the risk of pipe deformation and damage, and enhancing stability during transport.

[0022] The flexible roller includes a cylindrical inflatable roller body 2-2 and a roller hub 2-3. The roller hub supports the inflatable roller body and connects to the roller shaft, forming a rotating pair with the roller shaft. In this embodiment, the roller hub structure is similar to that of a car tire, specifically including a shaft hole and annular sealing grooves at both ends of the roller hub. The shaft hole accommodates the roller shaft, thus achieving a stable connection between the inflatable roller body and the roller shaft and enabling its rotation. The annular sealing grooves are located at both ends of the roller hub and are used to fit the edges of the inflatable roller body. Through a sealing design, the inflatable roller body is effectively fixed, ensuring that it will not shift or leak under high pressure or dynamic loads, while maintaining airtightness. This structure, through the matching of the sealing grooves with the edges of the inflatable roller body, not only enhances the sealing performance of the overall device but also allows the inflatable roller body to provide elastic support, thereby improving the protection and adaptability of the roller for the pipeline.

[0023] One end of the roller is mounted to the inner or outer support of the idler roller via a quick-release pin 5. Two locking sleeves 6 are mounted on the roller, each equipped with a locking screw to lock the axial position of the sleeve relative to the roller. The flexible roller is clamped and fixed between the two locking sleeves. The quick-release pin allows for easy disassembly and maintenance of the roller. The two locking sleeves on the roller restrict the axial movement of the flexible roller. Each locking sleeve has a locking screw, which secures the sleeve to the designated position on the roller, thus achieving axial positioning and clamping of the flexible roller. The flexible roller is firmly clamped between the two locking sleeves, ensuring stability during rotation and preventing displacement or loosening. This structural design ensures both the secure installation and reliable operation of the flexible roller, while providing convenient disassembly and maintenance, improving the overall applicability and operational efficiency of the device.

[0024] In the aforementioned structure, multiple axially arranged flexible rollers can be installed on the roller as needed. This design flexibility allows the rollers to adapt to the conveying requirements of pipelines with different diameters and materials. Furthermore, existing or discarded wheels can be directly used for the flexible rollers, reducing costs and achieving resource reuse, resulting in high economic and environmental benefits. Regarding roller wear issues at key contact points, adjusting the arrangement of the flexible rollers allows less worn rollers to be moved to critical positions, thereby extending the overall lifespan of the device and reducing maintenance frequency and replacement costs. In addition, the multi-roller structure can more evenly distribute the load on the pipeline, further improving the stability and safety of the support.

[0025] Example 2

[0026] like Figure 2 The outer support of the idler roller is fixed to the base, and the inner support of the idler roller is installed on the base via a height-adjustable bracket assembly. A transverse guide rail 7 is installed on the inner support of the idler roller, and two slider seats 8 are mounted on the transverse guide rail. The two slider seats are respectively hinged to the inner end of the roller. In this embodiment, the height-adjustable bracket assembly includes a support frame 9 and a support pin 10 installed at the lower end of the support. The lower part of the inner support of the idler roller is hinged to the support frame via a pin. The base has N evenly spaced pin holes. The support pin is inserted into one of the pin holes, causing the support frame to form support for the inner support of the idler roller.

[0027] Furthermore, a pin hole is provided in the lower middle part of the inner support of the idler roller. The pin hole is hinged to the upper ends of two support frames through a pin. The support frame is a straight rod, and the axis of this pin is perpendicular to the V-shaped surface of the V. After the support frame is opened, the lower support pin is inserted into the pin hole to form a V-shaped support structure. To prevent the support pin from falling off after the device is flipped, the support pin and the pin hole can be connected by threads.

[0028] This structural design enhances the flexibility and functionality of the idler rollers through ingenious adjustable and guiding components. The outer support of the idler roller is fixed to the base, providing stable support, while the inner support is connected to the base via a height-adjustable bracket assembly, ensuring that its height can be flexibly adjusted to accommodate the conveying needs of pipes of different diameters or specifications. The design of the lateral guide rail and slider seat allows for lateral position adjustment of the rollers in the inner support, ensuring that the axes of the two idler rollers are always aligned after adjustment, thus improving the stability and accuracy of pipe conveying.

[0029] Furthermore, the height-adjustable support assembly achieves quick adjustment and secure support through the support frame, support pins, and multiple pin holes on the base, offering strong adaptability and convenient operation. Two sets of such idlers are installed at the front and rear of the base, forming a coaxial support axis. This allows the device to be used not only for pipeline transportation but also, through connection, to form a trailer, such as... Figure 3 As a transportation tool in engineering construction, this multi-functional design fully utilizes the structural features of the device, reducing equipment downtime and increasing its added value in engineering applications, thereby improving the overall economy and practicality of the device. At the same time, the structure is easy to disassemble and maintain, further enhancing its efficiency and ease of operation.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
