Description

Technical Field

[0001] This utility model relates to cables in the field of marine engineering, and in particular to a quick cable guide for the outer diameter of marine cables. Background Technology

[0002] In general shipbuilding, when cables pass through watertight bulkheads or hull plating requiring weathertightness or watertightness, cable perforation plates are used as transition pieces. These perforation plates are installed on the bulkhead, and the cables pass through their openings. The gaps are then filled with sealant to achieve pressure resistance and a waterproof seal. To ensure smooth cable passage and optimal sealing, the inner diameter of the perforation plate must precisely match the actual maximum outer diameter of the cable being passed through; typically, the inner diameter of the perforation plate should be approximately 0.5 mm larger than the maximum outer diameter of the cable.

[0003] Due to limitations in cable manufacturing processes, the diameter of the rubber outer sheath has tolerances. The outer diameter at different locations along the entire cable may fluctuate within a tolerance range of 0-1mm, and the location of the maximum outer diameter is uncertain. Therefore, it is necessary to accurately measure the maximum outer diameter along the entire length of the cable to determine the most suitable perforation plate size.

[0004] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: Traditional measurement methods, such as caliper measurement, paper strip wrapping, and projection, are inefficient and mostly involve single-point measurements, making it difficult to quickly and accurately determine the maximum outer diameter along the entire length. Because cables are coiled and bent, using a go gauge often causes jamming due to the cable not being perpendicular to the gauge, affecting measurement efficiency and accuracy. Shipyards currently commonly use go gauges for continuity testing, but this usually requires multiple workers, one holding the gauge and the other pulling the cable, resulting in low efficiency, high labor intensity, and difficulty in ensuring the cable's straightness during testing, further impacting measurement accuracy. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and address the problems of low efficiency in measuring cable outer diameter and inaccurate measurement position at the maximum diameter during the cable perforation plate and cable fitting process, this application provides a rapid cable guide for marine cables. This guide, through a split-type multi-stage clamping plate, efficiently and accurately measures the outer diameter of the entire cable, quickly determines the size of the fitting perforation plate, and enables single-person or semi-automated operation, thus solving the technical problem of measuring cable outer diameter and fitting the perforation plate.

[0006] The solution adopted by the embodiments of this application to solve the technical problem is: A rapid cable guide for marine cables includes a main frame, a cable guiding and clamping mechanism, and a multi-stage clamping plate detection module; The main frame includes a clamping bracket, a fixed clamping arm, a movable clamping arm, and a clamping spring. The fixed clamping arm and the movable clamping arm are symmetrically arranged on the upper and lower surfaces of the clamping bracket to form the cable inlet and outlet ends. A connecting rod is provided at one end of the clamping bracket, and the bottom of the movable clamping arm is hinged to the connecting rod through the movable clamping arm shaft. A clamping spring that provides clamping force is provided between the fixed clamping arm and the movable clamping arm to form an opening and closing clamp-like structure. The cable guiding and clamping mechanism is a double pulley clamping structure, including a clamping wheel and a damped clamping wheel, which are set at the cable inlet and outlet ends of the main frame to guide and straighten the cable when it enters and exits. The damping of the damped clamping wheel at the inlet end is used to straighten the cable. The multi-level clamping plate detection module includes multi-level clamping plates and clamping claws; the multi-level clamping plates are at least two levels of clamping plates with inner diameters decreasing sequentially along the cable travel direction, housed in a clamping plate bracket, used to measure the cable outer diameter. The clamping plates have a split, split structure, making it easy to insert or remove them from any position on the cable; the clamping claws are set on the clamping plate bracket, used to quickly lock or release the clamping plates.

[0007] In order to further solve the technical problems to be solved by the embodiments of this application, the pallet holder provided in the embodiments of this application is a rectangular plate with a stepped accommodating cavity that is open to the side, for accommodating multi-level pallets.

[0008] Furthermore, the card plate is a rectangular plate with a semi-circular arc, the semi-circular arc corresponding to the outer diameter of the cable, including card plate a, card plate b and card plate c, the inner diameter of card plate a, card plate b and card plate c decreases sequentially along the cable travel direction, and is inserted into the stepped receiving cavity of the card plate bracket.

[0009] Furthermore, the external geometric dimensions of the clamps are identical, allowing for complete replacement; when measuring cables of different diameters, only another set of clamps with different inner diameter specifications needs to be replaced.

[0010] Furthermore, the pallet holder is equipped with a transition bracket for hand support or connection to an external fixing device.

[0011] Positive effects: 1. High-efficiency detection: By integrating multiple levels of card plates with different inner diameters, the throughput of multiple aperture plate sizes can be simulated in a single pass, quickly selecting the appropriate aperture and greatly improving the detection efficiency.

[0012] 2. Ensure accuracy: The damped clamping wheel at the inlet provides reverse tension, which pulls the cable tight during passage to keep it straight, simulating real cabin passage conditions. This can accurately detect the maximum outer diameter of the cable along its entire length, avoiding misjudgments caused by cable bending.

[0013] 3. Easy to operate: The pallet features a split, quick-release design, allowing for assembly and disassembly at any point in the cable without needing to thread it through the cable end, making it suitable for continuous operation. It can be operated by a single person or used with magnetic holders and cable feeders for semi-automated cable handling, reducing labor intensity.

[0014] 4. High versatility: The clamping plate assembly can be replaced as a set, facilitating the measurement of cables with different diameter ranges. The guiding mechanism can adapt to various cable outer diameters and can accommodate cables with different stiffness levels by adjusting the damping force.

[0015] 5. Simulates reality: The material of the card plate can be the same as the actual perforated plate. The smoothness of the wire passing directly reflects the smoothness during actual installation, and the measurement results are reliable.

[0016] 6. Batch Inspection: This cable guide can be used manually or equipped with a transition bracket and clamped onto a universal magnetic base. When fixed with the universal magnetic base, it can be used in conjunction with cable rollers and cable feeding guide wheels for semi-automatic cable passing, suitable for large-batch cable inspection.

[0017] It is suitable for use as a fast cable guide for marine cables. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] according to Figure 1-7 As shown, a marine cable outer diameter quick-pass device includes a main frame, a cable guiding and clamping mechanism, and a multi-stage clamping plate detection module; The main frame includes a clamping bracket 7, a fixed clamping arm 1, a movable clamping arm 9, and a clamping spring 8. The fixed clamping arm 1 and the movable clamping arm 9 are symmetrically arranged on the upper and lower surfaces of the clamping bracket 7 to form the cable inlet and outlet ends. A connecting rod 11 is provided at one end of the clamping bracket 7. The bottom of the movable clamping arm 9 is hinged to the connecting rod 11 through the movable clamping arm shaft 10. A clamping spring 8 is provided between the fixed clamping arm 1 and the movable clamping arm 9 to provide clamping force, so that the movable clamping arm 9 has a tendency to close towards the fixed clamping arm 1, thereby forming an opening and closing clamp-like structure to straighten and clamp the cable entering and exiting the cable guide, making the cable smooth and adaptable to various outer diameter cables. The cable guiding and clamping mechanism is a double pulley clamping structure, including a clamping wheel 15 and a damped clamping wheel 18, which are set at the cable inlet and outlet ends of the main frame to guide and straighten the cable when it enters and exits. The damping of the damped clamping wheel 18 at the inlet end is used to straighten the cable. The multi-level clamping plate detection module includes a multi-level clamping plate and a clamping claw 6. The multi-level clamping plate consists of at least two levels of clamping plates with an inner diameter that decreases sequentially along the cable travel direction. These plates are housed in a clamping plate holder 7 and are used to measure the outer diameter of the cable. The clamping plates have a split, open-type structure, making them easy to insert or remove from any position on the cable. The clamping claw 6 is mounted on the clamping plate holder 7 and is used to quickly lock or release the clamping plates.

[0023] To ensure the stability of the structure in this embodiment, the fixed clamping arm 1 is an L-shaped strip plate with its bottom connected to the surface of the clamping plate bracket 7. The movable clamping arm 9 has the same shape as the fixed clamping arm 1. The movable clamping arm 9 is hinged to the connecting rod 11. The movable clamping arm shaft 10 is a stepped shaft. A pin 12 is provided at the end of the movable clamping arm shaft 10 to axially limit and fix the movable clamping arm shaft 10.

[0024] To further ensure the stability of the structure in this embodiment, a cable guide clamping mechanism is provided on the top of the movable clamping arm 9 and the fixed clamping arm 1. A clamping wheel 15 is provided on the top of both the movable clamping arm 9 and the fixed clamping arm 1 at the cable outlet end. A clamping wheel 15 is provided on the top of the movable clamping arm 9 at the cable inlet end, and a damped clamping wheel 18 is provided on the top of the fixed clamping arm 1. The cable enters at the inlet end and passes between the clamping wheel 15 and the damped clamping wheel 18. The damping of the damped clamping wheel 18 straightens the cable. The cable exits from between the two clamping wheels 15 at the outlet end. Under the action of the clamping wheel 15, the cable is straightened and kept straight.

[0025] To optimize the structure of this embodiment, the clamping wheel 15 is mounted on the top of the movable clamping arm 9 or the fixed clamping arm 1 via the clamping wheel shaft 13, and bearings 14 are embedded at both ends of the clamping wheel shaft 13 to support the rotation of the clamping wheel 15. The damping clamping wheel 18 is provided with a damping bearing 16 on its side, and the required damping force is adjusted by the fastening screw 17 so that the cable is smoothly tightened under the action of resistance.

[0026] To further optimize the structure of this embodiment, the clamping claw 6 is a strip-shaped structure. One end is linked to the card plate bracket 7 through the clamping shaft 5, and the other end is used to contact the card plate or disengage from the locking position when the clamping claw 6 is moved, so as to realize the quick installation and independent disassembly of the card plate.

[0027] To further optimize the structure of this embodiment, the pallet holder 7 is a rectangular plate with a stepped accommodating cavity that is open to the side, for accommodating multi-level pallets.

[0028] Preferably, the card plate is a rectangular plate with a semi-circular arc, the semi-circular arc corresponding to the outer diameter of the cable, including card plate a2, card plate b3 and card plate c4, the inner diameter of card plate a2, card plate b3 and card plate c4 decreases sequentially along the cable travel direction, and is inserted into the stepped receiving cavity of the card plate bracket 7.

[0029] As a standard technical choice, the card plates have the same external geometry and can be replaced as a set; when measuring cables of different diameters, only another set of card plates with different inner diameter specifications needs to be replaced.

[0030] In a preferred embodiment, the pallet holder 7 is equipped with a transition bracket 19 for hand support or connection to an external fixing device; the transition bracket 19 is clamped on a universal magnetic base, which can fix the cable guide on the metal platform. When the universal magnetic base is fixed, it works with the cable roller and the cable feeding guide wheel to perform semi-automatic cable passing.

[0031] Preferably, the transition bracket 19 is a strip plate with two through holes at both ends that match the bolt holes on the edge of the card plate bracket 7. The transition bracket 19 is fixed to the side of the card plate bracket 7 without clamping claw 6 by screws and wing nuts. The transition bracket 19 has a C-shaped clamp in the middle, which is clamped to the cylindrical rotating arm of the universal magnetic base by screw fastening. In actual use, the cable guide can be temporarily held or fixed by the transition bracket 19 depending on the construction environment.

[0032] As a standard technical choice, the clamping wheel 15, the damped clamping wheel 18, and the clamping plate are made of polytetrafluoroethylene or aluminum alloy to prevent scratching the cable surface.

[0033] The working process of this embodiment: Taking the testing of a reel of cable with a nominal outer diameter of φ16mm as an example, the operation steps for measuring the cable's outer diameter are as follows: 1. Based on the design department's requirements, calculate in advance the quantity and length of the required φ16mm cables; 2. Prepare a spool of φ16mm cable. Place the cable spool on the cable roller and set up the cable roller. At the same time, prepare an empty cable roller and two cable feeding guide rollers. It is advisable to place the two cable rollers with a certain height difference. 3. Lead the cable out from the cable roller, thread the cable end through two cable feed reels, then tie the cable end to the empty cable roller through another cable feed reel, and finally put the cable guide on the cable; based on the estimated cable outer diameter, use calipers to initially measure the cable outer diameter as φ15.8mm, select clamping plate c4 with an inner diameter of φ16mm, clamping plate b3 with an inner diameter of φ16.5mm, and clamping plate a2 with an inner diameter of φ17mm, form a three-stage clamping plate, install it on the clamping plate bracket 7, and fix it with clamping claws 6; 4. Fix the cable guide to the magnetic base via the transition bracket 19, and the magnetic base is attached to the metal workbench; fine-tune the position of the cable guide, and adjust the fastening screw 17 on the damping bearing 16 at the inlet end to tighten the cable so that the cable is appropriately taut. 5. Turn the handle on the empty cable roller to start pulling the cable, allowing it to pass through the cable guide at a constant speed, and place the cable reel onto the empty cable roller; 6. When the outer diameter of the cable is too large at a certain point and cannot pass through the clamping plate c4 with the smallest inner diameter, the cable will be stuck with the clamping plate c4, and the cable movement will be obstructed. At this time, the operator moves the clamping claw 6 to remove the clamping plate c4, then resets the clamping claw 6, continues to pull the cable, and rotates the handle on the empty cable roller to pass the cable. If the cable is stuck by the clamping plate b3 again, remove the clamping plate b3 in the same way and continue to rotate the handle on the empty cable roller to pass the cable. The cable can eventually pass through the clamping plate a2 smoothly. 7. When the cable reel length reaches the length of the first required cable as calculated, record the data of the clamping plate at this time in the record table. The inner diameter of the clamping plate a2 that finally passes through is φ17mm, which is the diameter of the opening plate that is suitable for this cable. At the same time, mark the cable code and mark the cable cut mark on the cable. 8. After the measurement is completed, reinstall the removed card plate and start the matching test of the outer diameter of the next cable with the perforated plate. Record the measurement results of the second cable in the record table until all the cables on a reel have been passed through. Match the corresponding perforated plate according to the data in the record table.

[0034] Features of this embodiment: This embodiment can simulate the passage of multiple perforated plate sizes in a single pass, quickly determining the maximum outer diameter of the cable and the appropriate inner diameter of the perforated plate. It has the advantages of high detection efficiency, accurate results, simple operation, and semi-automatic operation. It effectively solves the problems of low efficiency and poor accuracy of traditional cable outer diameter measurement methods, accurately matching the most suitable perforated plate for a large number of cables, and significantly improving the efficiency and accuracy of ship cable laying.
