Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology; more specifically, it relates to an underground pipeline winding repair device. Background Technology

[0002] Pipeline repair technology refers to technologies focused on maintaining, repairing, and improving existing pipeline systems. These technologies aim to extend the service life of pipelines, reduce maintenance costs, and ensure pipeline safety and reliability through efficient, economical, and environmentally friendly means. One such technology is an underground pipeline winding repair device, which is used to repair underground pipelines. It involves winding reinforcing materials inside the pipeline to repair damaged or corroded pipelines.

[0003] Currently, most existing spiral wound repair devices are of a fixed size, which may make it inconvenient to wound and repair pipes of different sizes according to different situations, thus reducing the applicability and repair efficiency of the devices. In addition, existing spiral wound repair devices are usually inconvenient to place and store. When the device needs to be moved from one location to another, the inconvenient storage design may increase transportation costs. At the same time, the design of the device may cause inconvenience in operation during use, which to a certain extent reduces the convenience and flexibility of the device. Therefore, there is an urgent need for an underground pipe spiral wound repair device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an underground pipeline winding repair device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an underground pipeline winding and repair device, including a rotating frame,

[0006] Both ends of the inner wall of the rotating frame are fixed with sleeves, and the inner bearings of the sleeves are connected to rotating rods. Both ends of the rotating rods are threaded with first connecting plates. The inner walls of the rotating frame are provided with sliding grooves on both sides, and the inner grooves are used to slide and engage the rotating cylinder. The inner part of the rotating cylinder is threaded with a second connecting plate.

[0007] Preferably, a turntable is provided at the middle position of the rotating rod, and both ends of the rotating rod are provided with threads, and the two sets of threads are opposite to each other. Through the above operation, when the user rotates the turntable, the rotating rod as a whole can be rotated, thereby causing the two sets of first connecting plates to move inward or outward synchronously.

[0008] Preferably, a limiting groove is provided inside the sleeve, and the limiting groove is in contact with one end surface of the first connecting plate. Through the use of the limiting groove, the first connecting plate can be more stable when moving, and at the same time, the first connecting plate is prevented from detaching from the inside of the sleeve when moving.

[0009] Preferably, one end of the second connecting plate is provided with a limiting block, and the surface size of the limiting block is larger than the surface size of the rotating cylinder. By using the limiting block, the inconvenience caused by the second connecting plate moving out of the rotating cylinder can be avoided.

[0010] Preferably, a groove is provided on one end surface of both the first and second connecting plates. When the pipeline is repaired, the repair material can be placed inside the groove, thereby better fitting with the inner wall of the pipeline and avoiding displacement or leakage when the repair material fits the inner wall of the pipeline.

[0011] Preferably, circular grooves are provided at the inner walls of the two ends of the rotating frame, and the surface of the circular grooves is in contact with the surface of the second connecting plate. Through the cooperation of the circular grooves, the second connecting plate can be made more stable when moving.

[0012] Preferably, grips are fixed at both ends of the second receiving plate. By using multiple sets of grips in combination, the equipment can be picked up and placed more easily.

[0013] The technical effects and advantages of this utility model are as follows: This utility model drives the first connecting plate to move inward or outward synchronously by rotating the rotating rod, and then drives the second connecting plate to move inward or outward by rotating the rotating cylinder. When one end surface of the first connecting plate and the second connecting plate is in contact with the inner wall surface of the pipe, the rotation of the rotating rod and the rotating cylinder can be stopped. Through the above operation, pipes of different sizes can be wound and repaired according to different situations, thereby improving the applicability and repair efficiency of the equipment.

[0014] By rotating the rotating rod and the rotating cylinder, the first and second connecting plates are moved inward. When the first and second connecting plates are both inside the rotating frame, the equipment can be placed. At the same time, the use of multiple sets of grips makes it easier to pick up and move the equipment, thereby avoiding inconvenience in operation and improving the convenience and flexibility of the equipment to a certain extent.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The pipe repair involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, this embodiment proposes an underground pipeline winding repair device, including a rotating frame 1. Both the upper and lower ends of the inner wall of the rotating frame 1 are fixed with sleeves 2, and the inner bearing of the sleeve 2 is connected to a rotating rod 3. Both ends of the rotating rod 3 are threadedly connected to a first connecting plate 4. The inner wall of the rotating frame 1 is provided with sliding grooves 5 on both sides, and the inner side of the sliding grooves 5 slides and engages with a rotating cylinder 6. The inner side of the rotating cylinder 6 is threadedly connected to a second connecting plate 7. A turntable is provided at the middle position of the rotating rod 3. Both ends of the rotating rod 3 are provided with threads, and the two sets of threads are opposite to each other. One end surface of the first connecting plate 4 and the second connecting plate 7 is provided with a groove. The inner wall of the rotating cylinder 6 at both ends of the rotating frame 1 is provided with a circular groove, and the surface of the circular groove is in contact with the surface of the second connecting plate 7.

[0023] In this embodiment, rotating the turntable drives the rotating rod 3 to rotate, thereby moving the first connecting plate 4 outward or downward. Then, rotating the two sets of rotating cylinders 6 causes the two sets of second connecting plates 7 to move inward or outward at both ends of the rotating frame 1. When the surfaces of the first connecting plate 4 and the second connecting plate 7 are in contact with the surface of the pipe, the movement of both can be stopped. Through the above operation, the size of the equipment can be moved according to the actual situation of the pipe, which improves the applicability of the equipment to a certain extent. The two sets of threads can be used in opposite directions to make the two sets of first connecting plates 4 move synchronously. The use of the circular groove makes the movement of the second connecting plate 7 more stable.

[0024] Example 2

[0025] like Figures 1 to 3 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a limiting groove is opened inside the sleeve 2, and the limiting groove is in contact with one end surface of the first connecting plate 4; a limiting block is provided at one end of the second connecting plate 7, and the surface size of the limiting block is larger than the surface size of the rotating cylinder 6; and a handle 8 is fixed at both ends of the second connecting plate 7.

[0026] In this embodiment, the use of the limiting groove can prevent the first connecting plate 4 from dislodging when moving inside the sleeve 2. The use of the limiting block can prevent the second connecting plate 7 from detaching from the rotating drum 6 when moving, thus avoiding inconvenience. The use of multiple sets of grips 8 can make the equipment more convenient to move or pick up.

[0027] Working principle: When using the equipment, firstly, place the repair material on the groove surface of the first connecting plate 4 and the second connecting plate 7. Then, rotate the rotating rod 3 to move the two sets of first connecting plates 4 outward synchronously. Next, rotate the rotating cylinder 6 to move the second connecting plate 7 outward. When the surface of the repair material is in contact with the inner wall surface of the pipe, the inner wall of the pipe can be wound and repaired. After the equipment is used, rotate the rotating rod 3 and the rotating cylinder 6 to move the first connecting plate 4 and the second connecting plate 7 inward. When the first connecting plate 4 and the second connecting plate 7 are completely stored inside the rotating frame 1, the equipment can be placed in a suitable position according to the handle 8. The above is the complete working principle of this utility model.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
