Description

Technical Field

[0001] The utility model relates to the technical field of gas delivery pipeline repair, in particular to a gas delivery pipeline lining flexible composite pipe repair device. Background Art

[0002] The flexible composite pipe lined with gas transmission pipeline is an advanced pipe used for the transportation of gases such as natural gas and gas. It is usually composed of an inner layer of flexible material and an outer layer of reinforced material. It has excellent pressure resistance, corrosion resistance and wear resistance. The lined flexible composite pipe can not only effectively prevent gas leakage and improve transportation efficiency, but also has good flexibility and adaptability, and can adapt to complex terrain and environmental conditions. Among them, the lined flexible composite pipe repair device is an efficient maintenance equipment designed to quickly repair local damage to the pipeline lining.

[0003] In the existing technology, the flexible composite pipe repair device lined with gas transmission pipelines is unable to expand and contract, which seriously restricts its application in complex pipeline structures or environments facing large temperature changes. Due to the lack of a flexible adjustment mechanism, the repair device is difficult to adapt to the dynamic deformation of the pipeline during operation, resulting in unsatisfactory sealing effect during the repair process, which may cause gas leakage or further damage to the pipeline. In addition, the non-expandable design makes it difficult to flexibly adjust the device during construction and maintenance, increasing the complexity and cost of operation. For a long time, this disadvantage has not only affected the repair effect, but also had a negative impact on the safety and operation efficiency of the pipeline. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a repair device for a flexible composite pipe lined with a gas conveying pipeline.

[0005] The repairing device of claim 1, wherein the first support frame is a cylinder pressure vessel and the first support frame is a cylinder pressure vessel, the first support frame is a cylinder pressure vessel and the like.

[0006] Preferably, the bottom end of the repair operation machine is provided with a front wheel module and a rear wheel module, and the front wheel module and the rear wheel module are driven to rotate by an internal motor. The bottom end of the repair operation machine is slidably connected to a lifting support round platform, and the lifting support round platform is driven to rotate by a first cylinder, and the first cylinder is fixed inside the repair operation machine. In the prior art, the disadvantage of the flexible composite pipe repair device lined with a gas transmission pipeline cannot automatically move in the pipeline. This limits the flexibility and efficiency of the repair work. In complex pipeline layouts and long-distance pipeline repairs, manual intervention will become frequent and cumbersome, which will cause delays in the repair process and increase the workload of operators. In addition, the lack of automatic movement function will limit the repair range and fail to effectively cover all damaged areas in the pipeline, thereby affecting the overall effect of the repair and increasing the likelihood of gas leakage and safety risks. To address this problem, the utility model adopts a mobile and stable support structure. When a designated location needs to be repaired, it is started. The motors driving the front wheel module and the rear wheel module inside the repair operation machine drive the repair operation machine to move. After reaching the designated position, the first cylinder is started. Driven by the first cylinder, the lifting support table descends and supports the ground, making the repair operation machine more stable during the work process, thereby significantly improving the flexibility and efficiency of the repair work. The application of this technology will reduce manual intervention, shorten the repair time, and reduce the workload of operators. At the same time, the automatic movement function can ensure full coverage of the damaged area in the pipeline and achieve efficient repair, thereby effectively reducing the risk of gas leakage and enhancing the safety and reliability of the pipeline.

[0007] Preferably, the repair support cylinder is rotatably connected to the top of the repair operation machine. A first bevel gear is fixed to one side of the repair support cylinder, and a second bevel gear is meshed with the surface of the first bevel gear. The second bevel gear is driven to rotate by a second motor, and the second motor is fixed to the top of the repair operation machine. In the prior art, the flexible composite pipe repair device for gas pipeline lining cannot rotate autonomously, which limits its repair ability in complex pipeline environments. This design makes it difficult for the device to achieve full-scale positioning and repair when facing tortuous or irregular pipelines, resulting in low repair efficiency and unstable repair quality, increasing the need for manual intervention, thereby extending the repair time and increasing operational risks. To address such problems, the present invention adopts a rotating structure. When rotation is required, the second motor is started. Driven by the second motor, the second bevel gear rotates, which in turn drives the first bevel gear to rotate, causing the repair support cylinder to rotate, thereby significantly improving its repair ability in complex pipeline environments, thereby achieving full-scale positioning and repair, improving repair efficiency and quality, reducing the need for manual intervention, shortening repair time and reducing operational risks. This will make the repair process more intelligent and automated, and enhance the safety and economy of overall pipeline maintenance.

[0008] Preferably, a screw hole for mounting the repair module is provided on one side of the repair module component support seat. This ensures stable installation and convenient replacement of the repair module, ensures accuracy and safety during the repair process, and improves the maintenance efficiency and adaptability of the equipment, making it more flexible and reliable during use.

[0009] Preferably, the bottom of the lifting support circular platform is provided with anti-slip grooves, which enhance the friction between the circular platform and the ground, thereby effectively preventing sliding and tipping, which not only improves the safety and stability of the equipment, but also ensures safety during operation, reduces the risk of accidents, and ensures the reliable use of the equipment in various environments.

[0010] Preferably, the lifting support platform adopts a trapezoidal design. This design not only gives the device greater stability but also effectively lowers the center of gravity. This shape of the platform provides a larger contact area with the ground, thereby dispersing pressure and reducing the risk of tipping. In addition, the trapezoidal structure can better guide the user's center of gravity, ensuring balance during lifting and moving, thereby improving overall safety and ease of use.

[0011] Preferably, a repair module mounting seat is provided on the top of the repair operation machine, which can effectively enhance the flexibility and versatility of the equipment. The mounting seat facilitates the user to quickly replace and install different repair modules to meet various repair needs, reducing operation time and cost while ensuring the efficiency and accuracy of the repair process.

[0012] Beneficial effects:

[0013] 1. In the prior art, the flexible composite pipe repair device lined with gas transmission pipelines is unable to expand and contract, which seriously restricts its application in complex pipeline structures or environments facing large temperature fluctuations. Due to the lack of a flexible adjustment mechanism, the repair device cannot adapt to the dynamic deformation of the pipeline during operation, resulting in unsatisfactory sealing effect during the repair process, which may cause gas leakage or further damage to the pipeline. In addition, the non-expandable design makes it difficult to flexibly adjust the device during construction and maintenance, increasing the complexity and cost of operation. For a long time, this disadvantage has not only affected the repair effect but also had a negative impact on the safety and operational efficiency of the pipeline. To address such problems, the present invention adopts a telescopic structure to achieve flexible adaptation to different pipeline structures and temperature changes. This will significantly improve the sealing effect during the repair process, reduce the risk of gas leakage, and effectively prevent further damage to the pipeline. In addition, the flexibility of the repair device will simplify the construction and maintenance process, reduce the difficulty and cost of operation, thereby improving the safety and operational efficiency of the pipeline and ensuring the safe and stable operation of the gas transmission system.

[0014] 2. In the prior art, the disadvantage of the flexible composite pipe repair device lined with a gas transmission pipeline is that it cannot automatically move in the pipeline, which limits the flexibility and efficiency of the repair work. In complex pipeline layouts and long-distance pipeline repairs, manual intervention will become frequent and cumbersome, which will cause delays in the repair process and increase the workload of operators. In addition, the lack of automatic movement function will limit the repair scope and fail to effectively cover all damaged areas in the pipeline, thereby affecting the overall effect of the repair and increasing the likelihood of gas leakage and safety risks. To address such problems, the utility model adopts a mobile and stable support structure to significantly improve the flexibility and efficiency of the repair work. The application of this technology will reduce manual intervention, shorten the repair time, and reduce the workload of operators. At the same time, the automatic movement function can ensure full coverage of the damaged area in the pipeline and achieve efficient repair, thereby effectively reducing the risk of gas leakage and enhancing the safety and reliability of the pipeline.

[0015] 3. In the prior art, the flexible composite pipe repair device for the gas transmission pipeline lining cannot rotate autonomously, which limits its repair capability in complex pipeline environments. This design makes it difficult for the device to achieve all-round positioning and repair when facing tortuous or irregular pipelines, resulting in low repair efficiency and unstable repair quality, increasing the need for manual intervention, thereby extending the repair time and increasing operational risks. To address such problems, the present invention adopts a rotating structure to significantly improve its repair capability in complex pipeline environments, thereby achieving all-round positioning and repair, improving repair efficiency and quality, reducing the need for manual intervention, shortening repair time and reducing operational risks. This will make the repair process more intelligent and automated, and enhance the safety and economy of overall pipeline maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0023] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

[0025] Reference Figure 1-4A gas pipeline lining flexible composite pipe repair device includes a repair operation machine 1, a repair support cylinder 101 is provided on the top of the repair operation machine 1, the inner wall of the repair support cylinder 101 is rotatably connected to a first screw rod 102, the other end of the first screw rod 102 is rotatably connected to a support block 104, the surface of the first screw rod 102 is threadedly connected to a first support frame 103, the first screw rod 102 is driven to rotate by a first motor 105, the first motor 105 is fixed inside the support block 104, and a fixing frame 106 is fixed on the surface of the support block 104. The frame 106 is fixed to the inner wall of the repair support tube 101, and a second support frame 107 is fixed to one side of the support block 104, and a sliding track 108 is fixed to one side of the second support frame 107. The surface of the sliding track 108 is slidably connected to a sliding component 109, and a third support frame 110 is fixed to one side of the sliding component 109. A repair module component bearing seat 111 is fixed to one side of the third support frame 110, and one side of the third support frame 110 is rotatably connected to a rotating connecting plate 113, and the other end of the rotating connecting plate 113 is rotatably connected to one side of the first support frame 103. In the prior art, the flexible composite pipe repair device for the lining of a gas transmission pipeline is unable to be extended and retracted, which seriously restricts its application in complex pipeline structures or environments facing large temperature changes. Due to the lack of a flexible adjustment mechanism, the repair device is difficult to adapt to the dynamic deformation of the pipeline during operation, resulting in unsatisfactory sealing effect during the repair process, which may cause gas leakage or further damage to the pipeline. In addition, the non-extendable design makes it difficult to flexibly adjust the device during construction and maintenance, increasing the complexity and cost of operation. For a long time, this disadvantage has not only affected the repair effect, but also had a negative impact on the safety and operating efficiency of the pipeline. To address such problems, the present invention adopts a telescopic structure. When telescopic adjustment is required, the first motor 105 is started, and the first screw 102 is rotated under the drive of the first motor 105, so that the first support frame 103 moves. Under the action of the rotating connecting plate 113, the third support frame 110 and the sliding assembly 109 move, thereby driving the repair module component support seat 111 to extend and retract.

[0026] The bottom end of the repair operation machine 1 is provided with a front wheel module 2 and a rear wheel module 201, which are driven to rotate by an internal motor. The bottom end of the repair operation machine 1 is slidably connected to a lifting support round platform 202, which is driven to rotate by a first cylinder 203, and the first cylinder 203 is fixed inside the repair operation machine 1. In the prior art, the disadvantage of the flexible composite pipe repair device for the gas transmission pipeline lining cannot move automatically in the pipeline is that this limits the flexibility and efficiency of the repair work. In complex pipeline layouts and long-distance pipeline repairs, manual intervention will become frequent and cumbersome, which will cause delays in the repair process and increase the workload of operators. In addition, the lack of automatic movement function will limit the repair range and fail to effectively cover all damaged areas in the pipeline, thereby affecting the overall effect of the repair and increasing the likelihood of gas leakage and safety risks. To address such problems, the present invention adopts a mobile stable support structure. When repair is required at a designated position, the motor driving the front wheel module 2 and the rear wheel module 201 inside the repair operation machine 1 is started to drive the repair operation machine 1 to move. After reaching the designated position, the first cylinder 203 is started. Driven by the first cylinder 203, the lifting support platform 202 descends and is supported by the ground, making the repair operation machine 1 more stable during operation.

[0027] The repair support cylinder 101 is rotatably connected to the top of the repair operation machine 1. A first bevel gear 3 is fixed to one side of the repair support cylinder 101. A second bevel gear 301 is meshed with the surface of the first bevel gear 3. The second bevel gear 301 is driven to rotate by a second motor 302. The second motor 302 is fixed to the top of the repair operation machine 1. In the prior art, the flexible composite pipe lining repair device for gas transmission pipelines cannot rotate autonomously, which limits its repair capability in complex pipeline environments. This design makes it difficult for the device to achieve all-round positioning and repair when facing tortuous or irregular pipelines, resulting in low repair efficiency and unstable repair quality, increasing the need for manual intervention, thereby extending the repair time and increasing operational risks. To address such problems, the present invention adopts a rotating structure. When rotation is required, the second motor 302 is started. Driven by the second motor 302, the second bevel gear 301 rotates, thereby driving the first bevel gear 3 to rotate, causing the repair support cylinder 101 to rotate.

[0028] A repair module mounting screw hole 112 is provided on one side of the repair module component support seat 111. This ensures stable installation and convenient replacement of the repair module, ensuring accuracy and safety during the repair process, while improving the maintenance efficiency and adaptability of the equipment, making it more flexible and reliable during use. Anti-slip grooves 204 are provided on the bottom of the lifting support circular table 202. This enhances the friction between the circular table and the ground, thereby effectively preventing sliding and tipping, which not only improves the safety and stability of the equipment, but also ensures safety during operation, reduces the risk of accidents, and ensures the reliable use of the equipment in various environments. The lifting support circular table 202 adopts a trapezoidal circular table design. The trapezoidal circular table design not only gives the equipment higher stability, but also effectively lowers the center of gravity. This shape of the circular table can provide a larger contact area with the ground, thereby dispersing pressure and reducing the risk of tipping. In addition, the trapezoidal structure can better guide the user's center of gravity, ensuring balance during lifting and moving, and improving overall use safety and operational convenience. A repair module mounting seat 303 is provided on the top of the repair operation machine 1. It can effectively improve the flexibility and versatility of the equipment. The mount allows users to quickly replace and install different repair modules to adapt to various repair needs, reducing operation time and costs while ensuring the efficiency and accuracy of the repair process.

[0029] The working principle of the present invention is as follows: when telescopic adjustment is required, the first motor 105 is started, and the first screw rod 102 is rotated under the drive of the first motor 105, so that the first support frame 103 moves, and the third support frame 110 and the sliding assembly 109 are moved under the action of the rotating connecting plate 113, thereby driving the repair module component bearing seat 111 to telescope. When it is necessary to repair the designated position, the motor that drives the front wheel module 2 and the rear wheel module 201 inside the repair operation machine 1 is started to drive the repair operation machine 1 to move. After reaching the designated position, the first cylinder 203 is started. Under the drive of the first cylinder 203, the lifting support circular table 202 is lowered and supported by the ground, making the repair operation machine 1 more stable during work. When rotation is required, the second motor 302 is started, and under the drive of the second motor 302, the second bevel gear 301 is rotated, thereby driving the first bevel gear 3 to rotate, so that the repair support cylinder 101 is rotated.
