AI Technical Summary
The existing cable metal armored shield cannot directly process the metal pipe on the cable core during processing, resulting in the need to use single or double buckle metal hoses. During the pipe penetration process, it is easy to cause friction damage between the cable core and the inner wall of the metal hoses. The existing manual brushing lubricant is inefficient and easy to contaminate.
A cable metal hose lubrication and pipe penetration device is designed, including a lubrication chamber, a first adjustment device, a hopper and a second adjustment device. By wrapping a plastic wrap belt outside the cable core, and setting a lubrication port between the laying tray and the metal hose inlet, using silicone oil or butter as lubricating liquid, the friction between the cable core and the inner wall of the metal hose is reduced.
It effectively reduces the friction between the cable core and the inner wall of the metal hose, avoids damage to the wire core, and improves lubrication efficiency, avoids leakage and contamination of lubricating fluid.

Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of cables, and in particular relates to a lubricating tube threading device for a cable metal hose. Background Art
[0002] The existing cable metal armor shielding layer can be directly processed on the cable core by wrapping or interlocking armoring because its armor shielding is a strip material.
[0003] The existing metal armor shielding layer of a cable cannot be directly processed on the cable core by wrapping or interlocking armoring due to different technical requirements and processing methods. This type of cable requires a single-buckle or double-buckle metal hose. The metal material can only be processed into a metal hose first, and then the cable core is inserted into the tube, and the metal hose is used as a metal armor shielding layer. There is currently no such type of tube-threading equipment on the market, and this type of cable is usually used in occasions with extremely small bending radius, so the cable itself is extremely flexible, and the inner wall of the metal hose is corrugated rather than a smooth wall. Usually, the inner diameter of the metal hose and the outer diameter of the cable core are within 2mm. When threading the tube, the cable core is prone to friction with the inner wall of the metal hose, which can damage the wire core. However, there are many problems with manual lubricant application, such as low efficiency, uneven application, and lubricant dripping and contaminating the ground. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cable metal hose lubrication pipe threading device. In order to ensure that the cable core is not damaged during the passage of the cable core in the metal hose, the present invention wraps a layer of plastic tape around the cable core, and sets a lubrication port between the pay-off reel and the metal hose inlet. Silicone oil or butter is used as a lubricant, and the cable core is passed through the inside so that the plastic tape of the cable core is coated with lubricant, thereby reducing the friction between the cable core and the inner wall of the metal hose. The cable core can be coated with lubricant to reduce the friction between the cable core and the inner wall of the tube during the tube threading process, and the problem of lubricant leakage and contamination of the ground will not occur.
[0005] In order to achieve the above technical objectives, the technical solution adopted by the embodiment of the present invention is: A cable metal hose lubrication pipe threading device, comprising a lubrication bin, the two ends of the lubrication bin having an inlet and an outlet, the lubrication bin being provided with a first adjustment device, a hopper and a second adjustment device, the first adjustment device and the second adjustment device being used to adjust the position of the cable core in the lubrication bin, the hopper being used to add lubricating liquid into the lubrication bin; The inlet and outlet at both ends of the lubrication bin are arranged at a height greater than the height of the middle of the lubrication bin, and the inlet and / or outlet form an angle of 10° to 30° with the middle of the lubrication bin; A soft brush device for brushing away excess lubricating liquid on the surface of the cable core is arranged between the outlet and the second adjusting device.
[0006] Further, the first regulating device is arranged close to the inlet, the second regulating device is arranged close to the outlet, and the hopper is arranged between the first regulating device and the second regulating device.
[0007] Furthermore, a visual window is provided on the lubrication bin for observing the position of the cable core in the lubrication bin.
[0008] Further, the first adjusting device and the second adjusting device include a knob device, a connecting rod, a fixing device and a clamp; The knob device is located at one end of the connecting rod and is used to adjust the position of the clamp in the lubrication bin; The fixing device is arranged at the middle part of the connecting rod, and the connecting rod and the outer wall of the lubrication bin are fixed by the fixing device; The clamp is arranged at the other end of the connecting rod, and the clamp is located inside the lubrication bin.
[0009] Furthermore, the connection rod can be driven to move up and down relative to the lubrication bin by rotating the knob device, thereby adjusting the position of the clamp inside the lubrication bin.
[0010] Furthermore, the clamp is a semicircular ring with its opening facing downward, and the outer surface of the clamp fits with the inner wall of the lubrication bin.
[0011] Furthermore, the inlet and / or the outlet transitions to the middle of the lubrication bin through an arc.

[0017] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "inside, outside", "up, down", "left, right", etc. are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.
[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0019] Example 1 like Figure 1 and 2 As shown, a cable metal hose lubrication pipe threading device includes a lubrication bin 3, with an inlet 1 and an outlet 6 at both ends of the lubrication bin 3, and a first adjustment device 2, a hopper 7 and a second adjustment device 4 are provided on the lubrication bin 3. The first adjustment device 2 and the second adjustment device 4 are used to adjust the position of the cable core in the lubrication bin 3, and the hopper 7 is used to add lubricating liquid into the lubrication bin 3; The height of the inlet 1 and the outlet 6 at both ends of the lubrication bin 3 is greater than the height of the middle of the lubrication bin 3, and the inlet 1 and the outlet 6 form an angle of 10° to 30° with the middle of the lubrication bin 3; the elevation angle design of the inlet 1 and the outlet 6 can effectively prevent the lubricating liquid from leaking from the device; A soft brush device 5 is provided between the outlet 6 and the second adjusting device 4 for brushing away excess lubricating liquid on the surface of the cable core.
[0020] When the angle between the inlet 1 and the outlet 6 and the middle of the lubrication bin 3 is less than 10°, the lubricating liquid is easy to leak from the lubrication bin 3, and the lubricating liquid stored in the lubrication bin 3 cannot completely immerse the cable core in the cable core. When the angle between the inlet 1 and the outlet 6 and the middle of the lubrication bin 3 is greater than 30°, the inlet 1 and the outlet 6 at both ends of the lubrication bin 3 and the cable core generate excessive friction, which may cause damage to the cable core. Therefore, the angle is set to 10°~30°.
[0021] The first regulating device 2 is disposed near the inlet 1 , the second regulating device 4 is disposed near the outlet 6 , and the hopper 7 is disposed between the first regulating device 2 and the second regulating device 4 .
[0022] The lubrication bin 3 is also provided with a visual window 8 for observing the position of the cable core in the lubrication bin 3 .
[0023] like Figure 3 As shown, the first adjusting device 2 and the second adjusting device 4 both include a knob device 41, a connecting rod 42, a fixing device 43 and a clamp 44; The knob device 41 is located at one end of the connecting rod 42 and is used to adjust the position of the clamp 44 in the lubrication bin 3; The fixing device 43 is arranged in the middle of the connecting rod 42, and the connecting rod 42 and the outer wall of the lubrication bin 3 are fixed by the fixing device 43; The clamp 44 is disposed at the other end of the connecting rod 42 , and the clamp 44 is located inside the lubrication bin 3 .
[0024] By rotating the knob device 41, the connecting rod 42 can be driven to move up and down relative to the lubrication bin 3, thereby adjusting the position of the clamp 44 inside the lubrication bin 3, and thus adjusting the position of the cable core in the lubrication bin 3 through the clamp 44 to ensure that the cable core is completely immersed in the lubricating liquid.
[0025] The clamp 44 is a semicircular ring with its opening facing downward, and the outer surface of the clamp 44 fits against the inner wall of the lubrication bin 3 .
[0026] The inlet 1 and the outlet 6 are connected to the middle of the lubrication chamber 3 through an arc transition, which can reduce the friction between the cable core and the lubrication chamber 3.
[0027] Lubricating liquid including silicone oil or butter is added to the lubrication bin 3 from the feeding hopper 7. Since the setting height of the inlet 1 and the outlet 3 is greater than the height of the middle part of the lubrication bin 3, a certain volume of lubricating liquid can be stored inside the lubrication bin 3. The cable core enters the lubrication bin 3 from the inlet 1 of the lubricating pipe threading device. The position of the cable core in the lubrication bin 3 is adjusted by using the first adjusting device 2 at the end where the inlet 1 is located and the second adjusting device 4 at the end where the outlet 6 is located, so that the cable core can be completely immersed in the lubricating liquid, and the excess lubricating liquid on the surface of the cable core is brushed off by the soft brush device 5, and the cable core leaves the lubrication bin 3 from the outlet 6.
[0028] The provision of the soft brush device 5 can not only reduce the waste of lubricating liquid, but also ensure that the cable core will not leave the lubricating pipe threading device with excess lubricating liquid and drip onto the ground, causing environmental pollution.
[0029] When the position of the cable core in the lubrication bin 3 is adjusted by using the first adjustment device 2 and the second adjustment device 4, the position of the cable core in the lubrication bin 3 is observed through the visual window 8 provided on the lubrication bin 3, thereby ensuring that the cable core is completely immersed in the lubricating liquid.
[0030] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
