Description

Technical Field

[0001] The utility model relates to the technical field of cable processing tools, in particular to a mineral cable sheath stripping device. Background Technique

[0002] Mineral cables are mainly composed of conductors wrapped with inorganic mineral insulation materials, and have significant advantages such as high temperature resistance, fire protection, corrosion resistance, and large current carrying capacity. They are widely used in fields with extremely high safety requirements such as high-rise buildings, subways, nuclear power plants, and chemical industries. During actual installation and maintenance, it is often necessary to strip the outer sheath of mineral cables to expose the internal conductors for subsequent wiring operations or inspection and repair.

[0003] However, during the stripping process of the existing mineral cable sheaths, they cannot flexibly adapt to the changes in cable sizes when dealing with mineral cables of different thicknesses, which easily leads to cable sliding and offset during the stripping process. In addition, it is inconvenient to adjust the cutting depth, and the sheath may not be completely removed, or even the cable body may be damaged, affecting the service life of the cable. In addition, traditional stripping methods mostly rely on manual operation, resulting in high labor intensity and low stripping efficiency. Therefore, a mineral cable sheath stripping device is proposed. Content of the Utility Model

[0028] Refer to Figures 1 - 4, an embodiment provided by the present utility model: a mineral cable sheath stripping device, including a support frame 1, a regulating handle 2 is rotatably connected to the support frame 1, a regulating threaded rod 3 is fixedly connected to the regulating handle 2, the thread directions at both ends of the regulating threaded rod 3 are opposite, both ends of the regulating threaded rod 3 are connected with threaded blocks 4, a driving motor 5 is fixedly installed on a group of threaded blocks 4, an output end of the driving motor 5 is fixedly connected with a driving roller 6, the driving roller 6 is rotatably connected to the threaded block 4, a driven roller 7 is rotatably connected to the other group of threaded blocks 4, a placing plate 8 is fixedly connected to the support frame 1. By rotating the regulating handle 2, the self-adaptive clamping of the two groups of threaded blocks 4 to different mineral cable thicknesses is realized through the setting of the regulating threaded rod 3, ensuring that the cable is firmly clamped between the driving roller 6 and the driven roller 7, avoiding sliding or offset during the stripping process. At the same time, with the cooperation of the return spring 14 and the limiting plate 13, the mineral cable is further limited to prevent the cable from rolling during the stripping process, ensuring the stability of the cable during the stripping process.

[0029] In addition, an installation frame 9 is fixedly connected to the support frame 1, a sliding rod 10 is slidably connected to the installation frame 9, a fixed block 11 is fixedly connected to one end of the sliding rod 10, a connecting plate 12 is fixedly connected to the other end of the sliding rod 10, a limiting plate 13 is fixedly connected to the connecting plate 12, a return spring 14 is sleeved on the sliding rod 10, and both ends of the return spring 14 are respectively fixedly connected to the installation frame 9 and the connecting plate 12. A lifting threaded rod 15 is threadedly connected to the installation frame 9, a lifting handle 16 is fixedly connected to one end of the lifting threaded rod 15, a lifting plate 17 is rotatably connected to the other end of the lifting threaded rod 15, a cutting blade 18 is fixedly connected to the bottom of the lifting plate 17, a fixing plate 19 is fixedly connected to the lifting plate 17, a limiting groove 20 is opened on the installation frame 9, the regulating threaded rod 3 is rotatably connected to the support frame 1, the threaded block 4 is slidably connected to the support frame 1, the driving roller 6 and the driven roller 7 are symmetrically arranged, the placing plate 8 is located between the regulating threaded rod 3 and the installation frame 9, the shape of the placing plate 8 is arc-shaped, there are two groups of sliding rods 10 and they are symmetrically arranged, there are two groups of limiting plates 13 and return springs 14 and they are symmetrically arranged, the cutting blade 18 is located above the two groups of limiting plates 13, the fixing plate 19 is slidably connected to the limiting groove 20, and there are two groups of fixing plates 19 and they are symmetrically distributed on both sides of the lifting plate 17. Through the setting of the lifting threaded rod 15, the height of the cutting blade 18 can be adjusted by rotating the lifting handle 16, and then the cutting depth can be adjusted to meet the cutting requirements of mineral cable sheaths with different thicknesses. When cutting, the driving motor 5 is started. Through the setting of the driving roller and the driven roller 7, the mineral cable can be driven to move, and the cable sheath will be cut while moving, reducing the labor intensity of the operator and shortening the stripping time.

[0030] Working principle: When using this mineral cable sheath stripping device, the operator passes the mineral cable whose sheath needs to be stripped through the driving roller 6 and the driven roller 7, and uses the placing plate 8 to support the cable body of the mineral cable between the driving roller 6 and the driven roller 7. By manually rotating the adjusting handle 2, the adjusting handle 2 drives two sets of threaded blocks 4 to move on the support frame 1 through the adjusting threaded rod 3. Since the thread directions at both ends of the adjusting threaded rod 3 are opposite, the two sets of threaded blocks 4 will approach each other, so that the distance between the two sets of threaded blocks 4 can be adjusted according to the thickness of different mineral cables, thereby restricting the mineral cable between the driving roller 6 and the driven roller 7. Place one end of the mineral cable between the two limiting plates 13. Due to the thickness of the mineral cable itself, it will squeeze the return spring 14 to both sides through the limiting plate 13. At this time, the sliding rod 10 will slide on the mounting frame 9. Then, under the elastic force of the return spring 14, the two limiting plates 13 will rebound and fit on the surface of the mineral cable, which can prevent it from rolling randomly during the subsequent stripping of the cable sheath and will not be too tightly attached to the cable, avoiding affecting the subsequent cutting operation. Then, the lifting handle 16 can be rotated. The lifting handle 16 drives the lifting plate 17 and the cutting blade 18 on the lifting plate 17 to move downward through the lifting threaded rod 15. At this time, the fixing plate 19 will slide in the limiting groove 20 to make the lifting plate 17 move down smoothly. As the cutting blade 18 moves downward, the cutting blade 18 will cut open the mineral cable sheath. The cutting depth of the cutting blade 18 can be adjusted according to the thickness of different mineral cables, which is convenient to use. Then, the operator can pull the cut part of the mineral cable a certain distance away from the mounting frame 9, and then start the driving motor 5. The driving motor 5 drives the driving roller 6 to rotate, thereby driving the mineral cable to move on the placing plate 8 towards the mounting frame 9. At the same time, the movement of the mineral cable will drive the driven roller 7 to rotate together. As the mineral cable continues to move, the sheath of the cable passing through the mounting frame 9 will be cut open by the cutting blade 18, and the operation is convenient, saving time and effort.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
