Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for sealing sleeves, and in particular to an on-site auxiliary device for sealing sleeves of gas pipelines. Background Technology

[0002] During pipeline construction, various factors can lead to water ingress or other impurities, making emergency repairs extremely complex. This not only causes significant economic losses but also brings a series of negative social impacts. Therefore, it is necessary to implement "temporary sealing" during construction to prevent impurities and accumulated water from entering.

[0003] Currently, common plugging materials include metal or rubber plugs, tape, airbags, and plugging sleeves. Among them, the plugging sleeve is different from other plugging methods. Instead, it is a tube sleeve that uses thermoplastic elastic material to meet the needs of three pipe diameters: De160, De200, and De250.

[0004] However, when using temporary sealing sleeves on large-diameter pipelines, it is crucial to ensure that on-site operators apply even force to ensure a tight fit between the sleeve and the pipeline. Using excessive force to pull or tug can cause the sleeve to break. Currently, the conventional installation method, based on field experience, involves rolling the sleeve to half its length, applying even force on both sides, and then slipping it onto the pipeline. This results in a tight fit, but because it requires the combined efforts of multiple people, installation remains laborious and controlling the fit is challenging. Utility Model Content

[0035] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0036] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Please refer to Figures 1 to 4 The present invention provides an on-site auxiliary device for a gas pipeline plugging sleeve, including a mounting base 1, a positioning ring 2, multiple inner support fingers 3, an adjusting ring 4, and a driving component 5.

[0038] Among them, the mounting base 1 serves as the basic support component of the entire device. Its shape is designed as a disc or other suitable shape according to actual usage requirements. The positioning ring 2 is connected to the surface of the mounting base 1. The front ends of the two are fixed together by common mechanical connection methods such as bolts and welding to ensure the firmness and reliability of the connection.

[0039] Furthermore, the positioning ring 2 is provided with multiple sliding grooves 23, which are evenly distributed in the circumferential direction of the positioning ring 2, providing a guide path for the sliding of the inner support finger 3.

[0040] Please refer to Figure 3 and Figure 4 In this embodiment, each inner support finger 3 corresponds to a sliding groove 23, and the two slide in cooperation. The inner support finger 3 is composed of a slider 31, a spreading part 32, and a positioning pin 33. The slider 31 is generally rectangular, and its shape is adapted to the sliding groove 23, so that it can slide smoothly in the sliding groove 23.

[0041] In addition, the upper part of the slider 31 is provided with a rotating seat 311, and the supporting part 32 is an arc-shaped plate structure with rotating shafts 321 on both sides. The rotating shafts 321 are rotatably connected to the rotating seat 311, so that the supporting part 32 can rotate relative to the slider 31 within a certain angle range.

[0042] Thus, when the expansion part 32 rotates toward the center of the mounting base 1, the multiple expansion parts 32 become conical, which facilitates the removal of the gas pipeline sealing sleeve.

[0043] It should be noted that a positioning pin 33 is installed at the lower part of the slider 31, and the two can be fixed by welding or threaded connection. The shape of the positioning pin 33 is adapted to the positioning groove 42 on the adjusting ring 4, and the two are slidably connected to realize the linkage between the adjusting ring 4 and the inner support finger 3.

[0044] Please refer to Figure 3 In an optional embodiment, a plurality of connecting plates 21 are provided at the front end of the positioning ring 2. The connecting plates 21 are arc-shaped strips, one end of which is fixedly connected to the positioning ring 2 and the other end is fixedly connected to the mounting base 1.

[0045] The two can be connected by bolts or welding to form an integral structure, so that the positioning ring 2 is stably suspended on the mounting base 1. At the same time, the ring body 41 of the adjusting ring 4 is located outside the circumference formed by multiple connecting plates 21 and forms a rotational engagement with the connecting plates 21. This structure provides space for the rotation of the adjusting ring 4 and ensures the rotational stability of the adjusting ring 4.

[0046] Please refer to Figure 3 and Figure 4 In this embodiment, the adjusting ring 4 is rotatably disposed between the mounting base 1 and the positioning ring 2. The adjusting ring 4 is provided with a plurality of arc-shaped positioning grooves 42, which are evenly distributed in the circumferential direction of the adjusting ring 4 and correspond to and cooperate with the positioning pins 33 on the inner support finger 3.

[0047] More specifically, one end of the positioning groove 42 is close to the center of the ring body 41, and the other end is close to the outer periphery of the ring body 41. Therefore, the positioning pin 33 sliding along the positioning groove 42 will gradually move closer to or further away from the ring body 41, thereby achieving synchronous adjustment of the distance of multiple positioning pins 33 from the center of the ring body 41.

[0048] In this embodiment, the driving component 5 is a hydraulic push rod, the movable end of which is connected to the adjusting ring 4, and can drive the adjusting ring 4 to rotate. When the driving component 5 works and drives the adjusting ring 4 to rotate, the positioning pin 33, under the action of the positioning groove 42, drives the slider 31 to slide along the sliding groove 23, thereby causing the opening part 32 to move closer to or away from the center of the mounting base 1, so as to achieve uniform opening or contraction of the sealing sleeve.

[0049] In an optional embodiment, the housing of the drive component 5 is provided with a rotating shaft, which is rotatably connected to the mounting base 1 through a rotating support component such as a bearing. Since the drive component 5 is used to drive the adjustment ring 4 to rotate, its driving direction will change. The drive component 5 is rotatably connected through the rotating shaft, so that the drive component 5 can rotate to adaptively change its driving direction.

[0050] Furthermore, a connecting seat 43 is provided on the outside of the adjusting ring 4, and a C-shaped frame 44 is installed on the movable end of the driving component 5. The C-shaped frame 44 and the connecting seat 43 are connected by rotating connecting components such as pins to form a rotating pair.

[0051] When the driving component 5 is working, its movable end drives the connecting seat 43 to rotate through the C-shaped frame 44, which in turn drives the adjusting ring 4 to rotate, thereby realizing the opening or closing action of the inner support finger 3.

[0052] To facilitate the release of the sealing sleeves fitted around the multiple expansion portions 32, a hydraulic cylinder 10 is provided inside the slider 31. The hydraulic cylinder 10 is fixed inside the slider 31 by bolts or other mounting components, and its movable end extends from the front or side end of the slider 31 to the outside. An extension portion 322 is provided at the lower end of the expansion portion 32. The shape of the extension portion 322 is adapted to the shape of the movable end of the hydraulic cylinder 10, and the two abut against each other.

[0053] When the hydraulic cylinder 10 is working, its movable end extends or retracts, applying force to the extension 322, causing the spreading part 32 to rotate around the rotating shaft 321, thereby further adjusting the angle of the spreading part 32 relative to the slider 31 and enhancing the spreading effect on the sealing sleeve. An oil pump 6 is installed on the outer wall of the mounting base 1. The oil pump 6 is connected to the hydraulic cylinder 10 through an oil pipe. The oil pump 6 provides pressurized oil to the hydraulic cylinder 10, driving the operation of the hydraulic cylinder 10.

[0054] In an optional embodiment, the upper surface of the slider 31 is provided with a mounting plate 34, which is fixedly connected to the slider 31 by bolts. The positioning pin 33 is firmly connected to the mounting plate 34 by means of threaded connection or other means. This structure enhances the connection strength between the positioning pin 33 and the slider 31, ensuring that the positioning pin 33 can slide stably in the positioning groove 42 during the rotation of the adjusting ring 4, without loosening or falling off.

[0055] In another alternative embodiment, the mounting base 1 is designed as a two-platform structure with different heights. One platform is used to connect the drive component 5, and the other platform is used to connect the positioning ring 2. The chamfer 11 at the connection between the two platforms adopts a rounded transition or other suitable shape design to provide sufficient rotation space for the body of the drive component 5, so that the drive component 5 can rotate smoothly during operation without being restricted by the structure of the mounting base 1.

[0056] In addition, a T-shaped structure is formed in the longitudinal direction by communicating with the slide groove 23, and a baffle 35 is provided in the groove 22. The baffle 35 is fixed in the groove 22 by bolts, and its surface is in contact with the surface of the slider 31.

[0057] The baffle 35 serves to limit the slider 31, preventing it from excessively shifting or falling off when sliding in the groove 23, thus ensuring the stable operation of the inner support finger 3.

[0058] To facilitate the placement of the device with the sealing sleeve over the gas pipe, a handle 8 is provided on the outer periphery of the mounting base 1. The handle 8 is arc-shaped or ring-shaped, allowing operators to easily pick up, move, and place the entire device, thus improving the portability and ease of operation of the device.

[0059] In practical applications, operators only need to place the sealing sleeve over the multiple expansion parts 32 and control the drive component 5. The drive component 5 pushes the adjusting ring 4 to rotate relative to the mounting base 1 through its movable end. Under the rotation of the adjusting ring 4, the relative sliding of the positioning groove 42 and the positioning pin 33 causes the multiple expansion fingers to open synchronously away from the axis of the mounting base 1, and the sealing sleeve to be evenly expanded. The width of the expansion fingers is controlled to be greater than the diameter of the gas pipeline. At this time, the handle 8 is held to put the device over the end of the gas pipeline. Then, by controlling the oil pump 6, the multiple hydraulic cylinders 10 are retracted. Under the tension of the sealing sleeve, the multiple expansion parts 32 are forced to rotate around the slider 31 and shrink. At this time, the front end of the expansion part 32 is conical and shrinks inward, which can easily remove the sealing sleeve and put it directly over the front end of the gas pipeline. The device can be removed from the gas pipeline to complete the independent installation of the sealing sleeve by one person, which greatly improves the efficiency and safety of gas pipeline sealing operations.

[0060] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0061] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
