Description

Technical Field

[0001] This utility model relates to the field of gas pipeline maintenance technology, and in particular to a threaded tape wrapping tool suitable for confined operating spaces. Background Technology

[0002] In the fields of gas pipeline repair and water and electricity installation, threaded connections are a common method for connecting pipes and fittings. As a sealing material, the quality of threaded tape (such as PTFE tape) wrapping directly affects the sealing performance and safety of the connection. However, current threaded tape wrapping operations mostly rely on manual labor, which faces many technical problems in actual operations. For example, some gas pipeline repairs often involve narrow spaces such as corners, equipment gaps, and areas with dense intersections of multiple pipes. In these scenarios, the operator's range of hand movement is limited, making it difficult to stably control the direction and wrapping force of the tape. On the one hand, when wrapping by hand, the tape is prone to wrinkles and deviations due to uneven force, resulting in inconsistent sealing layer thickness and increasing the risk of gas leakage later. On the other hand, traditional tools are mostly long-handled straight-cylinder structures, which cannot adapt to multi-angle operations in narrow spaces. The tool head is prone to interference with surrounding pipes and equipment, forcing operators to adopt unconventional postures, which not only reduces wrapping efficiency but may also cause the tape to break due to operational errors, requiring rework.

[0003] Therefore, it is necessary to provide a new threaded tape wrapping tool suitable for confined operating spaces to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a threaded tape wrapping tool suitable for confined operating spaces.

[0005] The threaded tape wrapping tool provided by this utility model for use in confined operating spaces includes a central tube, a rotating disk rotatably connected inside the central tube, and an eccentric column offset from the center of the disk fixedly installed on the rotating disk. The eccentric column extends out of the central tube, and a rotatably connected guide wheel is installed at the extended end of the eccentric column. The central cylinder is fixedly mounted with a winding rod by a bracket, and the winding rod is located outside the central cylinder and parallel to the eccentric column. A rotating connecting sleeve is fitted on the winding rod.

[0006] Preferably, the sleeve ring is located above the guide wheel.

[0007] Preferably, the ferrule is wrapped with multiple layers of threaded adhesive tape.

[0008] Preferably, a threaded connector is fixedly installed at the bottom of the central cylinder.

[0009] Preferably, the threaded connector is equipped with a handle, and the top of the handle has a threaded hole A that matches the threaded connector.

[0010] Preferably, the threaded tape wrapping tool further includes an auxiliary component, which includes a sleeve with a sliding rod inserted into the sleeve, and the head of the sliding rod has a threaded B hole that matches the threaded connector.

[0011] Preferably, the sleeve has a threaded through hole on the sleeve wall near the opening, and a threaded fastening screw is inserted into the threaded through hole.

[0012] Compared with related technologies, the threaded tape wrapping tool provided by this utility model, suitable for confined operating spaces, has the following advantages: This invention uses a guide wheel to abut against the inner wall of the gas pipeline threaded interface, and then rotates the central connecting cylinder. During the rotation of the central connecting cylinder, the guide wheel is driven to roll along the inner wall of the gas pipeline threaded interface, so that the threaded tape on the sleeve ring can be wrapped around the gas pipeline threaded interface. After the first layer of threaded tape is wrapped, the pressing finger is removed and the wrapping continues, thus solving the problems of low efficiency and poor precision of traditional wrapping operations. It is especially suitable for complex maintenance scenarios such as gas pipelines. Furthermore, the guide wheel can accurately guide the tape released by the sleeve ring to wrap along the threaded trajectory, ensuring that the tape fits tightly and without wrinkles. The wrapping direction and number of layers are controllable, effectively improving the sealing reliability. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 5 This utility model provides a threaded tape wrapping tool suitable for confined operating spaces. The threaded tape wrapping tool for confined operating spaces includes a central cylinder 1, a rotating disk 2, an eccentric column 3, a guide wheel 4, a wrapping rod 5, and a connecting ring 6.

[0018] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 as well as Figure 3 The central tube 1 is equipped with a rotating disk 2 that is rotatably connected, and an eccentric column 3 that is offset from the center of the disk is fixedly installed on the rotating disk 2. The eccentric column 3 extends out of the central tube 1, and a rotatably connected guide wheel 4 is installed at the extended end of the eccentric column 3. The central tube 1 is fixedly equipped with a winding rod 5 through a bracket 11. The winding rod 5 is located outside the central tube 1 and is parallel to the eccentric column 3. A rotatably connected sleeve ring 6 is sleeved on the winding rod 5. The sleeve ring 6 is located above the guide wheel 4, and multiple layers of threaded tape are wound on the sleeve ring 6.

[0019] It should be noted that: multiple layers of threaded tape are pre-wound onto the connecting ring 6. Then, the guide wheel 4 on the eccentric column 3 is inserted into the gas pipeline threaded interface, with the connecting ring 6 located outside the gas pipeline threaded interface. When wrapping the threaded tape onto the gas pipeline threaded interface, the initial portion of the tape is adhered to the interface and pressed down with a finger. Then, the guide wheel 4 is pressed against the inner wall of the gas pipeline threaded interface, and the connecting cylinder 1 is rotated. During the rotation of the connecting cylinder 1, the guide wheel 4 is driven to roll along the inner wall of the gas pipeline threaded interface. The movement allows the threaded tape on the socket ring 6 to be wrapped around the threaded interface of the gas pipeline. After the first layer of threaded tape is wrapped, the pressing finger is removed and the wrapping continues. This solves the problems of low efficiency and poor precision in traditional wrapping operations, and is especially suitable for complex maintenance scenarios such as gas pipelines. Furthermore, the guide wheel 4 can accurately guide the tape released by the socket ring 6 to wrap along the threaded trajectory, ensuring that the tape is tightly adhered and wrinkle-free. The wrapping direction and number of layers are controllable (the number of layers can be accurately controlled by rotating the central connecting cylinder 1), effectively improving the sealing reliability.

[0020] This tool has a compact structure, and its overall radial dimensions are designed only around the pipe thread specifications. The eccentric column 3 drives the guide wheel 4 to penetrate deep into the inner ring of the pipe thread. The winding rod 5 is connected to the central cylinder 1 through the bracket 11 and is set parallel to the eccentric column 3, so that the connecting ring 6 is always close to the outside of the thread, avoiding interference between the tool parts and surrounding obstacles. Even in a narrow gap space, it can still achieve 360° rotation and winding, breaking through the space limitations of manual operation.

[0021] In the embodiments of this utility model, please refer to Figure 2 , Figure 4 as well as Figure 5 The bottom of the central cylinder 1 is fixedly installed with a threaded connector 12, and a handle 7 is installed on the threaded connector 12. The top of the handle 7 is provided with a threaded hole A 7a that matches the threaded connector 12. The threaded tape wrapping tool also includes an auxiliary component 8, which includes a sleeve 81. A sliding rod 82 is inserted into the sleeve 81 and is slidably connected. The head of the sliding rod 82 is provided with a threaded hole B 82a that matches the threaded connector 12. A threaded through hole is provided on the sleeve 81 near the cylinder opening, and a threaded fastening screw 83 is inserted into the threaded through hole.

[0022] It should be noted that the central cylinder 1 is equipped with a detachable handle 7 and auxiliary parts 8 to achieve multi-scenario operation adaptation. In relatively spacious areas, the handle 7 can be installed through the threaded connector 12, and the operator can easily rotate the central cylinder 1 by holding the handle 7, reducing hand fatigue. In extremely narrow areas where the handle 7 cannot be used, the handle 7 can be removed, and the sliding rod 82 of the auxiliary parts 8 can be connected to the threaded connector 12 through the threaded B hole 82a. After adjusting the extension length of the sliding rod 82 in the sleeve 81, it can be locked by the fastening screw 83. The sleeve 81 can be used to extend the operating arm to achieve long-distance or multi-angle rotation control, flexibly meeting the operation needs of different narrow spaces.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
