Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to pipeline repair auxiliary equipment. Background Art

[0002] Urban pipelines are one of the important infrastructures that support social development and ensure people's lives. After years of operation, various damages and leaks will inevitably occur due to corrosion, poor operation and management, causing serious economic losses. However, replacing new pipelines along the entire line is not only a huge project, but also costly and time-consuming.

[0003] Patent CN211738400U proposes an auxiliary device for pipeline repair. The repair mechanism uses a guide mechanism to enable smooth movement of the repair mechanism inside the pipeline. During repair, it is located in the center of the pipeline. The repair mechanism moves to the position of the recessed portion. The electric push rod drives the moving block to move, and the connecting rod drives the repair rod to prop up the recessed portion to repair the pipeline. The friction pad increases the friction between the repair rod and the inner wall of the pipeline. The rotating seat and the motor are set to enable the repair mechanism to be rotated and adjusted. Combined with the arrangement of multiple repair rods evenly distributed around, the repair effect at the position of the recessed portion is improved. This solves the problem that current pipeline repairs are usually repaired manually. For pipelines with deeper surface recesses, manual repair is difficult and requires the use of tools.

[0004] However, the technical means used in the scheme have the following problems: on the one hand, when using repair tools to repair the inner wall of the pipeline, it will cause the pipeline to vibrate, and the scheme lacks measures to fix the pipeline, so it is easy to cause the pipeline to shift during the repair process, thereby affecting the progress of the repair; on the other hand, since the position of the repair of the inner wall of the pipeline is uncertain, and after the repair device is sent into the interior of the pipeline, there are no fixed limiting measures. It is easy to cause the repair device and the part of the inner wall of the pipeline that needs to be repaired to be misaligned and offset during the repair process, resulting in reduced repair effect. Utility Model Content

[0005] The purpose of the utility model is to provide a pipeline repair auxiliary device to solve the problem in the prior art that when using repair tools to repair the inner wall of the pipeline, the pipeline will cause vibration, and due to the lack of measures to fix the pipeline, the pipeline is easily deviated during the repair process.

[0006] To achieve the above-mentioned object, a pipeline repair auxiliary device is provided, comprising a positioning cylinder, wherein both ends of the lower side of the positioning cylinder are fixedly connected to a fixing seat, an outer end of the fixing seat is fixedly connected to a sliding rod 1, a movable seat is movably connected to the sliding rod 1, a connecting frame is fixedly connected to the movable seat, and an outer end of the connecting frame is fixedly connected to a motor;

[0007] The output end of the motor passes through the connecting frame and is provided with a screw rod inwardly. The outer end of the screw rod is threadedly connected to a screw sleeve, and the other end of the screw sleeve is fixedly connected to a repair component mounting seat.

[0008] According to the pipeline repair auxiliary equipment, a fixing plate is fixedly connected to the screw sleeve, two ends of the fixing plate are fixedly connected to a second sliding rod, and the second sliding rod is slidably connected to the interior of the positioning cylinder.

[0009] According to the pipeline repair auxiliary equipment, a screw hole is provided on the slide rod, and a positioning bolt is connected to the inner thread of the movable seat and the screw hole.

[0010] According to the pipeline repair auxiliary equipment, the other end of the sliding rod is fixedly connected to the limit plate.

[0011] According to the pipeline repair auxiliary equipment, the inner bottom of the positioning cylinder is fixedly connected to the arc-shaped plate 1, and the outer ends of the positioning cylinder are fixedly connected to the cylinder mounting seats.

[0012] According to the pipeline repair auxiliary equipment, the outer end of the cylinder mounting seat is fixedly connected to the cylinder, and the extended end of the cylinder passes through the positioning tube and is provided with an arc-shaped plate 2 inwardly.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This patent can restrict the pipeline by setting a positioning cylinder, and set a repair component mounting plate on the moving end of the screw sleeve to install the repair component on the top. Under the action of the driving component and the screw assembly, the screw sleeve can drive the repair component to move linearly, so that it enters the interior of the pipeline to perform repair operations, maintain the accuracy of the repair position, and thus improve the overall repair effect while ensuring the stability of the pipeline;
