Description

Technical Field

[0001] This utility model relates to the technical field of pipeline repair devices, specifically to a pipeline repair device. Background Technology

[0002] Over long-term use, pipelines may develop cracks, leaks, and blockages due to natural wear and tear, corrosion, and external forces. These issues can affect the normal operation of the pipeline system and even pose serious safety hazards. Therefore, timely pipeline repair is crucial to ensuring the stability and safety of the pipeline system.

[0003] Currently, rotary spraying with a single nozzle is commonly used for pipeline repair. However, in actual operations, when the nozzle or key components of the equipment malfunction, the entire pipeline repair operation can be halted, severely impacting the repair progress and failing to meet the need for rapid repair completion.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a pipe repair device.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a pipeline repair device, comprising:

[0007] A retaining ring is fixedly connected to the robotic arm of a pipe-diameter spraying robot;

[0008] The support unit includes a support ring one rotatably connected to one end of the fixed ring, a support ring two coaxially distributed with the fixed ring and on the opposite side of the support ring one, and a folding assembly disposed between the support ring one and the support ring two to accommodate different pipe diameters. The folding assembly includes two sets of support rod mechanisms that are relatively distributed and rotatably disposed between the support ring one and the support ring two, and a screw drive mechanism for driving the support ring two to move closer to or away from the support ring one. Each set of support rod mechanisms consists of two support rods, and the ends where the two support rods intersect are rotatably provided with a rotating shaft.

[0009] Two nozzles are respectively installed at the joint ends of the two support rods and fixed to both ends of the rotating shaft, for parallel operation inside the pipeline.

[0010] Furthermore, the lead screw transmission mechanism includes a first support frame and a second support frame respectively disposed in the first support ring and the second support ring. The first support frame is provided with a lead screw that is threadedly connected to the second support frame, and the end of the lead screw corresponding to the first support frame is provided with a first motor.

[0011] Furthermore, an internal gear ring is provided on the inner wall of the support ring, and a gear meshes with the inner side of the internal gear ring. A transmission shaft passes through the end face of the gear, and a second motor fixed inside the fixed ring is provided on the transmission shaft at the end corresponding to the fixed ring.

[0012] Furthermore, each of the nozzles is provided with a delivery pipe at its liquid inlet end that communicates with the storage cylinder.

[0013] Furthermore, each of the two support rods is provided with a corresponding rotating pin seat at its two ends, and the two rotating pin seats are fixedly connected to the corresponding support ring one and support ring two.

[0014] Compared with existing technologies, this utility model has the following advantages: By using two nozzles and a redundant system structure, the two nozzles can work in parallel, enabling pipeline repair to be completed in a shorter time. Furthermore, if one nozzle malfunctions, the other can continue working, ensuring uninterrupted operation and preventing pipeline repair from stopping due to a single point of failure, thus improving repair efficiency. Additionally, the folding component allows for adjustment to accommodate different pipe diameters, making it suitable for repairing pipes with multiple diameters and simplifying operation.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figure 1-4 As shown, this utility model discloses a pipe repair device, comprising:

[0023] Fixed ring 1 is fixedly connected to the robotic arm of the pipe-diameter spraying robot;

[0024] The support unit includes a support ring 1 2 rotatably connected to one end of the fixed ring 1, a support ring 2 3 coaxially distributed with the fixed ring 1 and on the opposite side of the support ring 1 2, and a folding assembly 4 disposed between the support ring 1 2 and the support ring 2 3 to adapt to different pipe diameters. The folding assembly 4 includes two sets of support rod mechanisms 41 that are relatively distributed and rotatably disposed between the support ring 1 2 and the support ring 2 3, and a screw drive mechanism 42 for driving the support ring 2 3 to move closer to or away from the support ring 1 2. Each set of support rod mechanisms 41 is composed of two support rods 411, and the ends of the two support rods 411 that intersect are rotatably provided with a rotating shaft 412.

[0025] Two nozzles 5 are respectively installed at the ends of the two support rods 411 that meet, and are fixedly installed at both ends of the rotating shaft 412, for parallel operation inside the pipeline.

[0026] In specific implementation, a fixing ring 1 is bolted to the robotic arm of the pipe diameter spraying robot, and a support unit is installed on the end face of the fixing ring 1 away from the robotic arm. The support unit includes a support ring 1 2, a support ring 2 3, and a folding component 4, which can be adapted to the corresponding pipe for folding and adjustment. This makes the device of this embodiment suitable for pipe repair operations in multiple pipe diameters and has universal applicability.

[0027] Furthermore, by installing nozzles 5 on the ends of two connected support rods 411, and by installing two nozzles 5 in corresponding numbers on two sets of support rod mechanisms 41, the pipeline repair work can be completed in a shorter time. If one nozzle 5 fails, the other nozzle 5 can still continue to work, thereby ensuring that the work is not interrupted, avoiding the pipeline repair work from stopping due to a single point of failure, and improving the repair efficiency.

[0028] It should be noted that the support ring 2 has an annular groove machined on the end face of the corresponding fixed ring 1 and an annular guide rail that is adapted to the annular groove and welded on the end face of the fixed ring 1. The support ring 2 3 is coaxially mounted relative to the support ring 2 and symmetrically rotated between the support ring 2 and the support ring 2 3.

[0029] In one embodiment, the lead screw transmission mechanism 42 includes a first support frame 421 and a second support frame 422 respectively disposed in the first support ring 2 and the second support ring 3. The first support frame 421 is provided with a lead screw 423 that is threadedly connected to the second support frame 422. The end of the lead screw 423 corresponding to the first support frame 421 is provided with a first motor 424. This design, through the first support frame 421 and the second support frame 422 welded radially inside the support ring 1 2 and the support ring 2 3, and the first motor 424 and the lead screw 423 connected to the output shaft of the first motor 424 by a coupling, the first motor 424 is started, driving the lead screw 423 to rotate. This causes the second support frame 422, which is threadedly fitted on the lead screw 423, and the support ring 2 3, which is welded to the outside of the second support frame 422, to move away from or towards the support ring 1 2. The two sets of support rod mechanisms 41, which are symmetrically rotated between the support ring 1 2 and the support ring 2 3, play a limiting role in the movement of the lead screw transmission mechanism 42, realizing the linear movement of the support ring 2 3 under the action of the lead screw transmission mechanism 42.

[0030] In one embodiment, an internal gear ring 6 is provided on the inner wall of the support ring 2, and a gear 7 meshes with the inner side of the internal gear ring 6. A drive shaft passes through the end face of the gear 7, and a second motor 71 fixed inside the fixed ring 1 is provided on the drive shaft at the end corresponding to the fixed ring 1. With this design, by starting the second motor 71 mounted on the drive shaft at the end of the gear 7 through the internal gear ring 6 welded to the inner wall of the support ring 2 and the gear 7 meshing on one side of the internal gear ring 6, the gear 7 rotates. The meshing internal gear ring 6 drives the support ring 2 welded to the outside of the internal gear ring 6 and the related structures mounted on the support ring 2 to rotate circumferentially, thus achieving uniformity in pipe diameter repair operations.

[0031] In one embodiment, each of the nozzles 5 is provided with a delivery pipe 51 communicating with the storage cylinder at its liquid inlet end. This design establishes a delivery connection between the storage cylinder and the nozzles 5 by inserting the delivery pipe 51 into the liquid inlet end of the nozzle 5 and extending one end of the delivery pipe 51 to the storage cylinder.

[0032] It should be noted that the storage container contains chemical coatings for repairing pipelines.

[0033] It should be noted that the storage cylinder has two corresponding nozzles 5.

[0034] In one embodiment, corresponding rotating pin seats are respectively provided at the two disjoint ends of the two support rods 411, and the two rotating pin seats are fixedly disposed with the corresponding support ring 1 2 and support ring 2 3. With this design, by installing rotating pin seats at the disjoint ends of the two support rods 411, and welding and fixing the rotating pin seats to the corresponding ends of support ring 1 2 and support ring 2 3, the relative distance between the vertices of the two connected support rods 411 in the two sets of symmetrically installed support rod mechanisms 41 between support ring 1 2 and support ring 2 3 can be changed under the drive of the screw drive mechanism 42, thereby realizing the use of multi-diameter pipe repair spraying operations.

[0035] 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.

[0036] It should be noted that if the embodiments of this utility model involve directional indicators, such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, "several" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
