Description

Technical Field

[0001] This utility model relates to the field of cable chain keel technology, specifically a cable chain keel structure to prevent cable entanglement. Background Technology

[0002] Cable chain keels are key components used for support and guidance in industrial equipment, commonly found in cable drag chains and conveyor systems. Stress-distributed keels form a movable chain through multiple interconnected links. Curved cable chains employ a hinged link design, with each link connected by elastic hinges to form a flexible bending unit. When the cable chain moves along a curved path, the hinged structure allows relative rotation between links, distributing concentrated stress across multiple hinge points and preventing excessive stress at a single point, thus achieving uniform stress distribution.

[0003] Existing traditional stress-distributed cable chain keel structures rely on cable ties or rubber rings to concentrate and bind cables within the chain links. There are no fixed intervals between cables, which can easily lead to damage to the outer sheath due to frictional heat. Furthermore, localized stress concentration reduces the service life of the chain links. When the equipment folds back at high speed, the cables become entangled and slip relative to each other, increasing localized compressive stress. This not only shortens the cable life but also increases the noise of the cable chain operation. At the same time, the rigid binding method cannot adapt to cables of different diameters, and replacement and maintenance require the removal of the entire cable tie, which is cumbersome and results in long downtime. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a cable chain keel structure for preventing cable entanglement, including an upper connector, a chain being snapped into the inner wall of the upper connector, a lower connector being snapped into the end of the chain away from the upper connector, a lower locking platform being fixedly connected to the top of the chain, a fixing post being fixedly connected to the inner wall of the lower locking platform, a movable sleeve being rotatably connected to the surface of the fixing post, an upper locking platform being fixedly connected to the surface of the movable sleeve, a semi-circular hole one being opened at the bottom of the upper locking platform, a semi-circular hole two being opened at the top of the lower locking platform, a locking strip being fixedly connected to the bottom of the upper locking platform, a positioning groove being opened at the top of the lower locking platform, a locking hole being snapped into the positioning groove, and a fixing component being installed at the top of the upper locking platform.

[0005] The above technical solution consists of an upper connector, a chain link, a lower connector, a lower locking platform, a fixed column, a movable sleeve, an upper locking platform, a semi-circular hole one, a semi-circular hole two, a locking strip, a positioning groove, a locking hole, and a fixing component, forming a complete keel chain link. Each chain link is connected in series by locking to form a flexible and continuous support channel, so that the cable axial position remains fixed during the reciprocating motion of the drag chain, preventing the cable from crossing and wearing.

[0006] As a further improvement to the above scheme, when the top of the lower card platform contacts the bottom of the upper card platform, the lower card platform and the upper card platform are concentric.

[0007] The above technical solution ensures that the first semicircular hole and the second semicircular hole are accurately aligned, preventing misalignment from causing localized compression and deformation of the cable.

[0008] As a further improvement to the above scheme, the number of the first semicircular holes is set to several, and the several first semicircular holes are evenly distributed symmetrically at the bottom center of the card platform.

[0009] Through the above technical solution, several semi-circular holes are symmetrically distributed along the center of the bottom of the upper clamping platform, so that the same chain link can clamp multiple cables at the same time with equal spacing, preventing the cables from contacting and rubbing against each other.

[0010] As a further improvement to the above solution, the locking strip is sleeved inside the positioning groove, and both ends of the locking strip are engaged inside the locking holes.

[0011] Through the above technical solution, the two ends of the card strip are horizontally inserted into the card hole to form a secondary locking in the direction perpendicular to the positioning groove, so that the upper card platform will not open on its own when the cable chain returns at high speed, and maintains a stable closed state.

[0012] As a further improvement to the above solution, the fixing component includes a sliding groove, an arc-shaped sliding platform is slidably connected inside the sliding groove, a spring is fixedly connected to the inner wall of the lower locking platform, and a mounting box is fixedly connected to the top of the upper locking platform.

[0013] Through the above technical solution, the fixing component consists of a sliding groove, an arc-shaped sliding table, a spring, and a mounting box to form an elastic clamping unit, which provides continuous and adjustable normal pressure to the cable and limits and fixes the cable inside the semi-circular hole one and the semi-circular hole two.

[0014] As a further improvement to the above solution, the slide is located directly above the semicircular hole one, the bottom of the arc-shaped sliding platform is located inside the semicircular hole one, and the top of the spring is fixedly connected to the top of the inner wall of the mounting box.

[0015] The above technical solution uses an arc-shaped sliding table to compress a spring, generating downward pressure to fix the cable.

[0016] As a further improvement to the above solution, a limiting post is fixedly connected to the bottom of the inner wall of the arc-shaped sliding table, and a limiting plate is fixedly connected to the top of the limiting post.

[0017] Through the above technical solution, the limiting post and the limiting plate limit the upper and lower stroke of the arc-shaped sliding table to prevent the spring from being excessively compressed or stretched.

[0018] As a further improvement to the above solution, the limiting post is sleeved inside the spring, and the top of the limiting post penetrates the mounting box.

[0019] Through the above technical solution, the limiting post penetrates through the mounting box and is fitted inside the spring, forming a double guide inside and outside, thus preventing the spring from bending and failing.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This utility model opens a semi-circular hole 2 at the top of the lower card platform and opens several semi-circular holes 1 at the bottom of the upper card platform. After flipping and closing, each semi-circular hole 1 and semi-circular hole 2 form an independent circular channel. The cables are put into the corresponding channels one by one and then the card strip is locked, so that multiple cables maintain a fixed distance inside the keel, realize the separate arrangement, and avoid the mutual entanglement and friction damage caused by traditional bundling.

[0021] This utility model uses an arc-shaped sliding platform, a spring, and a limiting post. The spring continuously applies downward pressure, and the arc-shaped sliding platform rises and falls adaptively within the slide groove. This allows the same semicircular hole to fix cables of different diameters, preventing the cables from shaking during the movement of the cable between the first and second semicircular holes as it passes through the keel.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example: Please combine Figure 1-4This embodiment of a cable keel structure for preventing cable entanglement includes an upper connector 1, a chain 2 snapped into the inner wall of the upper connector 1, a lower connector 3 snapped into the end of the chain 2 away from the upper connector 1, a lower locking platform 4 fixedly connected to the top of the chain 2, a fixing post 5 fixedly connected to the inner wall of the lower locking platform 4, a movable sleeve 6 rotatably connected to the surface of the fixing post 5, an upper locking platform 7 fixedly connected to the surface of the movable sleeve 6, a semi-circular hole 8 opened at the bottom of the upper locking platform 7, a semi-circular hole 9 opened at the top of the lower locking platform 4, a locking strip 10 fixedly connected to the bottom of the upper locking platform 7, a positioning groove 11 opened at the top of the lower locking platform 4, a locking hole 12 snapped into the positioning groove 11, and a fixing component installed at the top of the upper locking platform 7.

[0026] During installation, the cable is placed inside the semi-circular hole 9, and then the upper clamping platform 7 is rotated around the axis of the fixing column 5 so that the clamping strip 10 is sleeved inside the positioning groove 11. When the bottom of the clamping strip 10 contacts the bottom of the positioning groove 11, the left and right ends of the clamping strip 10 are clamped inside the clamping hole 12. At this time, the cable is limited and fixed inside the lower clamping platform 4 and the upper clamping platform 7.

[0027] When the top of the lower card platform 4 contacts the bottom of the upper card platform 7, the lower card platform 4 and the upper card platform 7 are concentric.

[0028] The number of semicircular holes 8 is set to a certain number, and the number of semicircular holes 8 is symmetrically and evenly distributed at the bottom center of the card platform 7.

[0029] The clip 10 is fitted inside the positioning groove 11, and both ends of the clip 10 are engaged inside the clip hole 12.

[0030] The fasteners include a slide groove 13, an arc-shaped sliding platform 14 is slidably connected inside the slide groove 13, a spring 15 is fixedly connected to the inner wall of the lower mounting platform 4, and an installation box 18 is fixedly connected to the top of the upper mounting platform 7.

[0031] When fixed, the bottom of the arc-shaped sliding table 14 contacts the surface of the cable when it is inside the semi-circular hole 8 and the semi-circular hole 9, and the synchronous spring 15 applies pressure between the arc-shaped sliding table 14 and the cable to prevent the cable from shaking after it is fixed inside the semi-circular hole 8 and the semi-circular hole 9.

[0032] The slide 13 is located directly above the semi-circular hole 8, the bottom of the arc-shaped sliding platform 14 is located inside the semi-circular hole 8, and the top of the spring 15 is fixedly connected to the top of the inner wall of the mounting box 18.

[0033] A limiting post 16 is fixedly connected to the bottom of the inner wall of the arc-shaped sliding table 14, and a limiting plate 17 is fixedly connected to the top of the limiting post 16.

[0034] The limiting post 16 is sleeved inside the spring, and the top of the limiting post 16 passes through the mounting box 18.

[0035] The implementation principle of the cable keel structure for preventing cable entanglement in this embodiment is as follows: When installing the aluminum alloy cable keel, the cable is first placed inside the semi-circular hole 9. Then, the upper clamping platform 7 is rotated around the axis of the fixed column 5, so that the clamping strip 10 is sleeved inside the positioning groove 11. When the bottom of the clamping strip 10 contacts the bottom of the positioning groove 11, the left and right ends of the clamping strip 10 are clamped inside the clamping hole 12. At this time, the cable is limited and fixed inside the lower clamping platform 4 and the upper clamping platform 7, separating and fixing the cable that the keel needs to lift inside the keel, avoiding the cables from entangled with each other, which would lead to increased friction and damage to the cables.

[0036] When the cable needs to be replaced, use the lever to press the protrusions at both ends of the clip 10 simultaneously, so that the clip 10 is completely inside the positioning groove 11. Rotate the upper clip 7 around the fixed column 5 as the axis to separate the upper clip 7 from the lower clip 4, so that the cable can be adjusted and replaced.

[0037] With the fastener, when located inside the semicircular hole 8 and the semicircular hole 9, the bottom of the arc-shaped sliding table 14 contacts the surface of the cable. The synchronous spring 15 applies pressure between the arc-shaped sliding table 14 and the cable to prevent the cable from shaking after being fixed inside the semicircular hole 8 and the semicircular hole 9. It can also fix cables of different straight sizes.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
