Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for power engineering equipment, and specifically to a cable protection device for power engineering. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables, widely used in power transmission, signal control, and equipment connection, and are an indispensable key component in their installation and operation. Because cables are usually energized, the safety and reliability of their laying and fixing processes are crucial, thus requiring specialized protective devices for support and protection.

[0003] In related technologies, the clamping of cables in protective support devices often relies on a single-direction locking force, which has limited clamping effect and is difficult to effectively resist axial movement of the cable caused by its own weight, external traction, or environmental vibration. The overall constraint of the cable by the device is mostly local point fixation, lacking the ability to coordinate multi-point and multi-directional constraints along the cable direction, which makes the cable prone to loosening and displacement between fixed points, resulting in insufficient long-term stability of installation and positioning. In addition, the simple clamping structure is also lacking in adaptability and ease of operation when facing different wire diameters or occasions requiring frequent disassembly and assembly. Utility Model Content

[0004] The problem solved by this utility model is that the cable protection device has insufficient clamping effect on the cable and cannot effectively suppress the axial and lateral movement of the cable, resulting in unstable cable installation and positioning. A cable protection device for power engineering is proposed.

[0005] To solve the above problems, this utility model provides a cable protection device for power engineering, comprising: Base plate; A limiting seat is fixedly connected to the base plate, and the limiting seat has a through-hole for passing cables. A pair of lateral clamping assemblies are respectively disposed at both ends of the channel; each lateral clamping assembly includes a side pressure plate, a support plate and a positioning plate, the positioning plate and the support plate are respectively fixed to the limiting seat, the support plate is located at the lower edge of the channel opening and is used to carry the cable extending from the channel, the positioning plate is located above the channel opening, and the adjusting bolt passes through the top and bottom and is threadedly connected to the positioning plate, and its bottom end is rotatably connected to the side pressure plate; Rotating the adjusting bolt drives the side pressure plate to move closer to the support plate, thereby pressing the cable against the support plate.

[0006] Preferably, the limiting seat includes a placement plate and a pressing plate. The placement plate is connected to the middle of the base plate and is used to support the cable. The placement plate and the pressing plate are detachably connected and fixed by bolt locking components. The pressing plate and the placement plate together form the channel. The positioning plate and the support plate are respectively fixed to the pressing plate and the placement plate.

[0007] Preferably, a clamping bolt is threaded through and connected to the clamping plate, and a rubber pressure plate is rotatably connected to the bottom end of the clamping bolt. The clamping plate has an installation groove for accommodating the rubber pressure plate on the side facing the placement plate.

[0008] Preferably, each bolt locking member includes a pair of connecting plates, a through screw, and an anti-loosening nut. The pair of connecting plates are correspondingly connected to the placement plate and the pressing plate. The through screw passes through the pair of connecting plates and is locked and fixed by the anti-loosening nut.

[0009] Preferably, it further includes a pair of elastic support components, which are respectively disposed on the base plate and located at one end of the pair of lateral pressing components away from the limiting seat. Each elastic support component includes a pair of limiting sleeves coaxially disposed and a spring connected between the pair of limiting sleeves.

[0010] Preferably, one end of the limiting sleeve has a radially protruding flange, and a pair of flanges of a pair of limiting sleeves are arranged close to each other, with the spring connected between the pair of flanges.

[0011] Preferably, each of the elastic support components further includes a support plate, the lower end of each support plate being connected to the base plate and the upper end surface being an arc-shaped surface that fits and matches the cylinder wall of the limiting sleeve.

[0012] Preferably, each of the limiting sleeves has a support plate at both ends below it, and a pair of flanges are respectively engaged between the sides of two adjacent support plates facing each other.

[0013] Preferably, the bottom end of the adjusting bolt is rotatably connected to the side pressure plate via a second bearing seat.

[0014] Preferably, the side pressure plate facing the support plate and some of the support plate facing the side pressure plate are provided with arc-shaped grooves that fit and match the outer peripheral wall of the cable, and the inner surface of the arc-shaped grooves is bonded with an elastic anti-slip pad layer.

[0015] The beneficial effects of this utility model are: This utility model discloses a cable protection device for power engineering. A limiting seat and its through-passage are set on a base plate for axial fixation and limiting of the cable. Based on this, a pair of lateral clamping assemblies are set at both ends of the channel. Each lateral clamping assembly includes a support plate, a side pressure plate, and a driving component consisting of an adjusting bolt and a positioning plate. Rotating the adjusting bolt precisely and controllably converts the movement into a linear clamping motion of the side pressure plate towards the support plate, ensuring uniform and adjustable clamping force, avoiding skewing during the clamping process, and achieving rigid, non-destructive, and reliable clamping of the cable. Therefore, this cable protection device ensures that when the cable passes through, it is not only axially constrained in its middle but also subjected to adjustable clamping force from the vertical direction at its critical two ends, achieving precise and reliable clamping. This significantly improves the overall stability and positioning support effect of the cable line, providing a guarantee for its operational stability and safety. Attached Figure Description

[0019] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0020] In view of the problems existing in the above-mentioned related technologies, this utility model provides a cable protection device for power engineering.

[0021] Please see Figure 1 and Figure 2 This invention provides a cable protection device for power engineering, including a base plate 1, a limiting seat, and a pair of lateral clamping assemblies. The limiting seat is fixedly connected to the base plate 1, and the limiting seat has a through-hole channel 13 for the cable 8 to pass through. The pair of lateral clamping assemblies are correspondingly arranged at both ends of the channel 13. Each lateral clamping assembly includes a side pressure plate 23, a support plate 19, and a positioning plate 20. The positioning plate 20 and the support plate 19 are respectively fixed to the limiting seat. The support plate 19 is located at the lower edge of the opening of the channel 13 and is used to support the cable 8 extending from the channel 13. The positioning plate 20 is located above the opening of the channel 13. An adjusting bolt 21 passes through the positioning plate 20 vertically and is threadedly connected to the positioning plate 20. Its bottom end is rotatably connected to the side pressure plate 23. The support plate 19 and the side pressure plate 23 are arranged opposite each other vertically. Rotating the adjusting bolt 21 drives the side pressure plate 23 to move closer to the support plate 19 to press the cable 8 against the support plate 19.

[0022] It should be noted that this utility model provides a support, positioning, and extension guidance section for the cable 8 by setting a limiting seat connected to the middle of the base plate 1 and its through-hole channel 13. A pair of lateral clamping components are set at key positions at both ends of the channel 13, thereby achieving multi-point rigid positioning of the cable, which can effectively solve the axial movement and transmission sway caused by external forces during cable laying.

[0023] Furthermore, mounting holes 12 are provided on the base plate 1 for installing and fixing the entire cable protection device. The bottom end of the adjusting bolt 21 can be rotatably connected to the side pressure plate 23 through the second bearing seat 22. When the adjusting bolt 21 is rotated, the rotational torque it generates is absorbed by the second bearing seat 22, allowing the adjusting bolt 21 to rotate within the second bearing seat 22, while simultaneously transmitting the downward axial thrust to the side pressure plate 23. This achieves the vertical and smooth descent of the side pressure plate 23, ensuring that it can be precisely aligned with the support plate 19 below, thereby achieving stable and uniform clamping of the cable 8 and effectively preventing excessive local stress or damage to the cable 8 caused by the tilt of the side pressure plate 23. This rigid constraint applied directly from both ends of the channel 13 enhances the positioning firmness of the cable 8 at the cable protection device, which is equivalent to setting an anchor point at each end of a support positioning section of the cable 8. When cable 8 shakes due to external factors, the strong clamping at both ends can effectively block the axial transmission of shaking energy, preventing cable 8 from experiencing large-scale relative sliding (crossing) and resonant transmission shaking between adjacent cable protection devices. This significantly improves the overall stability and positioning support effect of cable 8, ensuring its operational stability and safety.

[0024] In one embodiment of the present invention, the limiting seat includes a placement plate 6 and a pressing plate 11. The placement plate 6 is connected to the middle of the base plate 1 and is used to support the cable 8. The placement plate 6 and the pressing plate 11 are detachably connected and together form a channel 13. The positioning plate 20 and the support plate 19 are respectively fixed to the pressing plate 11 and the placement plate 6.

[0025] It should be noted that the separate placement plate 6 and clamping plate 11 form an openable cable accommodating space, allowing the cable 8 to be directly supported on the placement plate 6 before being clamped and sealed. This eliminates the cumbersome operation of traditional protective devices that require the cable to be threaded through the end, greatly improving installation convenience, especially suitable for cable segments with large connectors. The channel 13 formed by the clamping plate 11 and placement plate 6 provides a stable and enclosed constraint environment for the cable 8, achieving effective axial restraint. Its separate nature also provides a dedicated protective space for the cable connector, preventing it from being directly exposed to the external environment. Furthermore, this detachable connection structure greatly facilitates subsequent line inspection and maintenance.

[0026] Please see Figure 3 In one embodiment of the present invention, a clamping bolt 15 is threaded through and connected to the clamping plate 11, and a rubber pressure plate 17 is rotatably connected to the bottom end of the clamping bolt 15. The clamping plate 11 has an installation groove 14 for accommodating the rubber pressure plate 17 on the side facing the placement plate 6.

[0027] It should be noted that the bottom end of the clamping bolt 15 is rotatably connected to the rubber pressure plate 17 via the first bearing seat 16, ensuring that the rubber pressure plate 17 does not rotate with the bolt, but instead moves in a straight downward motion. A washer 18 is also provided between the upper end face of the clamping bolt 15 and the pressure plate 11. The washer 18 ensures smooth rotation of the clamping bolt 15 and protects the body of the pressure plate 11. The mounting groove 14 guides and limits the lifting and lowering movement of the rubber pressure plate 17, ensuring its smooth operation, thereby applying the clamping force evenly to the cable 8 and effectively preventing the cable 8 from being damaged due to excessive local stress.

[0028] In one embodiment of the present invention, each bolt locking component includes a pair of connecting plates 7, a through screw 9, and an anti-loosening nut 10. The pair of connecting plates 7 are correspondingly connected to the placement plate 6 and the pressing plate 11. The through screw 9 passes through the pair of connecting plates 7 and is locked and fixed by the anti-loosening nut 10.

[0029] It should be noted that a pair of connecting plates 7 are fixed to the placement plate 6 and the clamping plate 11 respectively, providing precise positioning and reliable support points for the through screw 9. During installation, simply insert the through screw 9 into the aligned connecting plates 7 and then tighten the anti-loosening nut 10 to complete the fixation. The operation is simple, the connection strength is high, and it ensures that the locking assembly remains stable even under long-term vibration. This enables quick connection and locking between the clamping plate 11 and the placement plate 6.

[0030] Please see Figure 4 In one embodiment of the present invention, a pair of elastic support components are further included. The pair of elastic support components are respectively disposed on the base plate 1 and are respectively located at one end of the pair of lateral pressing components away from the limiting seat. Each elastic support component includes a pair of limiting sleeves 3 coaxially disposed and a spring 4 connected between the pair of limiting sleeves 3.

[0031] It should be noted that the elastic support assembly consisting of a pair of coaxial limiting sleeves 3 and connecting springs 4 on both sides of the limiting seat provides dynamic buffering and stable support for the entry and exit ends of the cable 8.

[0032] Specifically, the elastic support assembly forms a dynamic support channel combining rigid guidance and flexible support. A pair of limiting sleeves 3 provide precise coaxial guidance and basic support for the cable 8, effectively limiting the lateral displacement of the cable. The spring 4 connected between the two provides a continuous, flexible elastic lifting force when the cable 8 passes through, effectively compensating for the slight sag caused by the cable's own weight, while absorbing and dissipating the axial and lateral vibration and impact energy from the cable 8 (such as equipment operating vibration, accidental collisions, etc.), preventing stress from being directly transmitted to the connection point of the cable 8, thus providing good protection for the cable 8 and its connector. The central fixation of the elastic support assembly and the limiting seat, as well as the end constraint of the lateral clamping assembly, work together to form a cable protection device with rigid clamping in the middle and elastic buffering at both ends. This improves the stability and anti-interference ability of the cable 8 at the interface of the cable protection device, effectively suppresses abnormal shaking and cross-movement of the cable 8, and extends the service life of the cable, making it particularly suitable for power engineering scenarios that are sensitive to vibration or require high reliability.

[0033] In one embodiment of the present invention, a radially protruding flange portion 5 is formed at one end of the limiting sleeve 3, and a pair of flange portions 5 of a pair of limiting sleeves 3 are arranged close to each other, and a spring 4 is connected between the pair of flange portions 5.

[0034] It should be noted that the limiting sleeve 3 is a stepped sleeve, and the radially protruding structure of its flange 5 provides a natural positioning surface and a reliable mounting base for both ends of the spring 4, effectively preventing axial movement or radial slippage of the spring 4 during operation. The two limiting sleeves 3 themselves play a guiding and initial limiting role for the cable, while the spring 4 connected between them is responsible for absorbing vibrations and impacts from multiple directions. This ensures the stability, vibration resistance, and anti-sagging ability of the cable 8 when passing through it.

[0035] Please see Figure 4 In one embodiment of this utility model, each elastic support component further includes a support plate 2, the lower end of each support plate 2 being connected to the base plate 1, and its upper end surface being an arc-shaped surface that fits and matches the cylinder wall of the limiting sleeve 3. Each of the two ends of the limiting sleeve 3 is provided with a support plate 2, and a pair of flanges 5 are respectively engaged between the facing sides of two adjacent support plates 2.

[0036] It should be noted that the two support plates 2, facing each other, lock the opposite sides of a pair of flanges 5, while the opposite sides of the pair of flanges 5, close to each other, are connected by a spring 4. This prevents the limiting sleeve 3 from axially shifting, ensuring the stability of the structure. At the same time, the spring 4 plays an elastic role within its confined space. That is, the load and vibration of the cable 8 can be effectively transmitted to the spring 4 through the limiting sleeve 3, and flexibly absorbed and dissipated by the spring 4, while the elastic support component will not drift due to the reaction force.

[0037] In one embodiment of the present invention, the two ends of the spring 4 are snapped or welded to the flange portion 5 of a pair of limiting sleeves 3.

[0038] It should be noted that by pre-connecting the spring 4 and the two limiting sleeves 3 as a single unit, this elastic support assembly can be considered as an independent module during installation. The advantage of snap-fit ​​methods (such as using grooves or protrusions on the flange for mechanical interlocking) is rapid connection and ease of subsequent maintenance and component replacement, achieving detachable modularity. Welding, on the other hand, provides an extremely strong and permanent connection, ensuring that the spring 4 and the limiting sleeves 3 will never loosen during operation, making it particularly suitable for conditions with severe vibration and extremely high reliability requirements.

[0039] In one embodiment of this utility model, the side pressure plate 23 facing the support plate 19 and some of the support plate 19 facing the side pressure plate 23 are provided with arc-shaped grooves that fit and match the outer peripheral wall of the cable 8, and the inner surface of the arc-shaped grooves is bonded with an elastic anti-slip pad layer. It should be noted that the elastic anti-slip pad layer is in direct contact with the outer surface of cable 8, significantly increasing the coefficient of friction and providing strong static friction. This effectively prevents cable 8 from slipping or moving around in the clamping area when subjected to external vibration or axial tension, ensuring the long-term reliability of the clamping effect.

[0040] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
