Description

Technical Field

[0001] This invention relates to the field of cable installation equipment technology, specifically to a cable erection device at a corner position. Background Technology

[0002] In cable laying operations in fields such as power engineering and telecommunications engineering, corner locations are critical and challenging areas for cable installation. However, existing installation equipment has some shortcomings. For example, cables are often dragged directly along walls or supports at corners without dedicated guiding or load-bearing structures. Cables at corners must withstand significant friction, especially over long distances. The hard contact between the cable and the wall / support continuously wears down the cable sheath, easily leading to insulation damage, leakage, signal interference, and other safety hazards. Increased friction also reduces laying efficiency and increases labor costs. Furthermore, the lack of effective restraint at corners makes cables highly susceptible to displacement and detachment due to outdoor wind, equipment vibration, or impacts during maintenance, further threatening laying quality and operational safety.

[0003] For the reasons mentioned above, we propose a cable laying device at corner locations. Summary of the Invention

[0004] The purpose of this invention is to provide a cable laying device at a corner position to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cable laying device at a corner location includes a main bracket and a secondary bracket, with the secondary bracket rotatably mounted on both sides of the main bracket. The main bracket includes a support plate, a limiting plate, and a mounting panel. A clamping groove is formed within the support plate, creating a C-shape. Outwardly extending connecting plates are provided at both ends of the support plate, and rotating shafts are mounted on the connecting plates.

[0006] Rollers are evenly arranged on the rear side of the clamping groove, and limit plates are symmetrically arranged on the front side of the pallet. The limit plates are U-shaped and clamp the top and bottom surfaces of the pallet, thus limiting the inner cable. Limit rollers are movably sleeved on the limit plates.

[0007] The sub-bracket has the same structure as the main bracket, but the sub-bracket is one-fifth smaller than the main bracket. The sub-bracket also has a docking plate at the end near the main bracket, and the docking plate of the sub-bracket is installed on the pivot of the main bracket. The sub-bracket and the main bracket form a foldable whole, and the cable is laid along the sub-bracket and the main bracket.

[0008] Preferably, the docking plate has a fixing hole near the rotating shaft, and the rotating shaft is welded to the fixing hole. After the support plate is installed, it can rotate using the rotating shaft.

[0009] Multiple mounting panels are installed on the rear side of the top surface of the support plate. Each mounting panel consists of a base and a panel. The base is fixed to the support plate with bolts. The panel is rotatably mounted on the base. Anchor holes are symmetrically opened on the panel. The panel is attached to the wall and fixed in place by inserting anchors into the wall.

[0010] Preferably, the roller is made of insulated rubber and wrapped with a soft sheath on the outside. When the cable is placed in the clamping groove, it abuts against the roller, and the soft sheath provides cushioning for the cable. The cable is dragged in the clamping groove, and the rotation of the roller reduces friction on the cable sidewalls. The limiting roller is located vertically on the side of the clamping groove, limiting the cable and cooperating with the roller to reduce friction on the cable sidewalls.

[0011] Preferably, a latch lock is installed between the limiting plate and the support plate, and the limiting plate is clamped on the support plate and locked in place by the latch lock.

[0012] Preferably, the sub-bracket can be adjusted to rotate around the main bracket to adapt to various turning environments. The sub-bracket can rotate forward along the main bracket to adapt to acute-angle installation environments. The sub-bracket can rotate backward along the main bracket to adapt to obtuse-angle installation environments. The sub-bracket and main bracket are arranged in a straight line and installed on a flat wall.

[0013] Preferably, the combination structure of the two sub-brackets and the main bracket is extended by installing a docking plate at the other end of one sub-bracket. The docking plate is installed on the pivot of the other main bracket to extend the installation length of the cable bend.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention can significantly reduce cable friction and tension, preventing damage to the outer sheath and core. A roller with a soft sheath is installed in the C-shaped clamping groove of the main bracket, and a limiting roller is also installed on the limiting plate. During cable laying, the cable can directly abut against the roller and the limiting roller. The rotation of the roller converts the sliding friction between the cable and the bracket into rolling friction, greatly reducing the friction force experienced by the cable during dragging, thereby reducing the laying tension required by the cable and fundamentally avoiding cable sheath wear caused by traditional hard contact. Simultaneously, the roller's soft sheath uses a composite structure with a blend of neoprene and nitrile rubber as the inner layer and polyether-type polyurethane elastomer as the outer layer, possessing excellent elastic buffering performance. It can effectively absorb the instantaneous impact force during cable tensioning, such as the tension generated by dragging speed fluctuations and self-weight adjustment, preventing damage to the internal core of the cable due to impact and ensuring cable transmission performance and service life.

[0015] 2. Improve cable laying efficiency and quality, ensuring long-term stable operation. Reduced friction makes cable dragging smoother, reducing jamming during laying and significantly improving the efficiency of manual or mechanical laying, especially suitable for complex laying scenarios with long distances and multiple turns. The main bracket and sub-bracket form an adjustable angle structure through multiple independent rotating shafts, which can flexibly adapt to various laying requirements such as acute angles, obtuse angles, straight lines, and S / Z shapes, eliminating the need for customized brackets for different scenarios and reducing solution design and construction costs. At the same time, the U-shaped limiting plate with hook and loop lock can firmly limit the cable, effectively preventing the cable from shifting or falling off due to outdoor wind, equipment vibration, or external impact, ensuring accurate cable laying position and high long-term operational stability.

[0021] Please see Figure 1-4 The present invention provides the following technical solution: A cable laying device at a corner location includes a main bracket 100 and a secondary bracket 200. The secondary brackets 200 are rotatably mounted on both sides of the main bracket 100, and the cable is laid within the main bracket 100 and the secondary bracket 200. The main bracket 100 includes a support plate 101, a limiting plate 102, and a mounting panel 104. The support plate 101 has a clamping groove, which forms a C-shaped plate. Outwardly extending connecting plates are provided at both ends of the support plate 101, and a rotating shaft 105 is mounted on the connecting plates.

[0022] A fixing hole is provided on the docking plate near the rotating shaft 105. The rotating shaft 105 is welded to the fixing hole. After the support plate 101 is installed, it can be rotated using the rotating shaft 105. The rotating shaft 105 is a multi-layer independent rotating shaft 105, which can be used to adjust the rotation of the main support 100 and the auxiliary support 200 separately.

[0023] Multiple mounting panels 104 are installed on the rear side of the top surface of the support plate 101. Each mounting panel 104 includes a base and a panel. The base is fixed to the support plate 101 by bolts. The panel is rotatably mounted on the base, so that the panel has the function of rotation and adjustment. Anchor holes are symmetrically opened on the panel. After the panel is attached to the wall, it is fixed by inserting anchor rods into the wall.

[0024] Rollers 107 are evenly arranged on the rear side of the clamping groove. Each roller 107 is made of insulated rubber and covered with a soft sheath. When the cable is placed in the clamping groove, it can abut against the rollers 107, and the soft sheath provides excellent cushioning. Furthermore, the cable can be dragged within the clamping groove; the rotation of the rollers 107 reduces friction on the cable's sidewalls, extending its service life.

[0025] A limiting plate 102 is symmetrically arranged on the front side of the pallet 101. The limiting plate 102 is U-shaped and clamps the top and bottom surfaces of the pallet 101 to limit the inner cable. A support rod is arranged longitudinally on the limiting plate 102, and a limiting roller 103 is movably sleeved on the support rod. The limiting roller 103 is located vertically on the side of the clamping groove to prevent the cable from falling outward. At the same time, it cooperates with the roller 107 to reduce friction on the side wall of the cable.

[0026] A latch lock 106 is installed between the limiting plate 102 and the support plate 101. After the limiting plate 102 aligns with the latch lock 106, it is locked to limit the cable, making loading and unloading very convenient. The sub-support 200 has the same structure as the main support 100, but the sub-support 200 is one-fifth smaller than the main support 100. The sub-support 200 also has a docking plate at the end near the main support 100, and the docking plate of the sub-support 200 is installed on the pivot 105 of the main support 100. The sub-support 200 and the main support 100 form a foldable whole, and the cable extends in the clamping groove of the main support 100 and the sub-support 200.

[0027] The sub-bracket 200 can be adjusted to rotate along the main bracket 100 to adapt to various turning environments in different layouts. For example, the sub-bracket 200 can rotate forward along the main bracket 100 (as shown in the attached diagram). Figure 2 It can adapt to acute angle installation environments, while the sub-bracket 200 rotates backward along the main bracket 100 (as shown in the attached diagram). Figure 3 It can adapt to obtuse angle installation environments. Furthermore, the sub-bracket 200 and main bracket 100 are arranged in a straight line, allowing for installation on a flat wall. The two sub-brackets 200 rotate alternately along the main bracket 100 (as shown in the attached diagram). Figure 4 It can be arranged in an S or Z shape for installation, thus expanding its adaptability.

[0028] Meanwhile, the existing combination structure of the two auxiliary brackets 200 and the main bracket 100 can be expanded. For example, a docking plate can be installed at the other end of the auxiliary bracket 200 on one side, which can also dock with another main bracket 100, extending the installation length of the cable bend and enhancing the versatility of the erection device.

[0029] The pallet 101 and the limit plate 102 are made of glass fiber reinforced plastic, which can avoid safety hazards caused by accidental leakage of metal components. They also have anti-corrosion and lightweight properties, can adapt to harsh outdoor environments such as humidity and acid and alkali, and extend the overall service life of the device.

[0030] A 1.5mm thick epoxy resin insulating gasket is provided at the contact point between the base of the mounting panel 104 and the support plate 101 to prevent the mounting panel 104 from forming a conductive circuit with other metal components through the wall. At the same time, the anchor holes on the panel have built-in insulating sleeves with a sleeve length consistent with the panel thickness to prevent direct contact between the anchor rod and the panel, which could lead to leakage.

[0031] The inner wall of the clamping groove is covered with an insulating layer, which is a thick silicone rubber insulating pad. The surface of the insulating pad is treated with an anti-slip texture, which not only improves the insulation performance between the cable and the tray 101, but also prevents the cable from slipping when dragging.

[0032] The lock body and latch of the latch lock 106 are both made of engineering plastic. An insulating washer is added to the connection between the lock body and the limit plate 102 support plate 101 to ensure that the latch lock 106 does not become a conductive medium.

[0033] A dedicated grounding terminal is reserved on the mounting panel 104 of the main bracket 100, and the grounding terminal is isolated from the mounting panel 104 by an insulating gasket. When the device is used for high-voltage cable installation, the grounding terminal can be connected to the wall grounding system through the grounding wire. In the event of accidental leakage, the current can be quickly conducted to the ground through the grounding terminal to ensure the safety of personnel and equipment.

[0034] The soft cladding layer is a composite structure of chloroprene rubber, nitrile rubber blend, and polyether-type polyurethane elastomer.

[0035] Its inner layer is made of a blend of neoprene rubber and nitrile rubber, which has excellent aging resistance and oil resistance, and moderate elastic modulus, which can provide stable support elasticity for roller 107 and avoid long-term deformation under pressure.

[0036] The outer layer is made of polyether-type polyurethane elastomer, which has high wear resistance and excellent cushioning performance. It can reduce friction damage when the cable is dragged and adapt to low temperature environment, preventing the soft sheath from hardening and cracking in winter.

[0037] Silicone rubber sealing rings are provided at both ends of the roller 107. The sealing rings are embedded in the gap between the soft cover and the spindle to prevent dust and rainwater from entering the internal bearing of the roller 107, and at the same time further improve the overall insulation and sealing performance of the roller 107.

[0038] Working principle: This invention enables the sub-bracket 200 to be adapted to various cable laying scenarios, such as acute angles, obtuse angles, straight lines, and S / Z shapes, through multi-angle rotation and modular expansion. The sub-bracket 200 rotates around the main bracket 100 via the rotating shaft 105, and the angle can be adjusted according to the actual laying requirements.

[0039] When the auxiliary bracket 200 rotates forward, the main and auxiliary brackets 200 form an angle of less than 90°, which is suitable for sharp angle installation scenarios such as wall corners and equipment gaps.

[0040] When the secondary bracket 200 rotates backward, the main and secondary brackets 200 form an angle greater than 90°, which is suitable for obtuse angle installation scenarios such as open spaces and curved walls.

[0041] When laying cables in a straight line, the auxiliary bracket 200 and the main bracket 100 are rotated into a straight line to fit against the flat wall, which meets the requirements for laying long-distance straight cables.

[0042] The S / Z-shaped brackets have two auxiliary brackets 200 that rotate alternately along the main bracket 100, with one side moving forward and the other side moving backward, forming a continuous turning structure that is suitable for complex cabling environments, such as multi-level equipment rooms and narrow passages.

[0043] If it is necessary to extend the cable laying length, a connecting plate can be added to the other end of one side of the auxiliary bracket 200 to connect with the new main bracket 100, forming a main-auxiliary-main-auxiliary chain extension structure, breaking through the length limitation of a single device and improving versatility.

[0044] This invention optimizes the protection against cable leakage risks. The support plate 101 and the limiting plate 102 are made of glass fiber reinforced plastic, replacing the traditional metal bracket, thus preventing metal leakage from the source.

[0045] An epoxy resin insulating gasket is provided between the base of the mounting panel 104 and the support plate 101 to prevent the panel from forming a conductive circuit with other metal components through the wall.

[0046] The panel anchor holes have built-in insulating sleeves to prevent direct contact and conductivity between the anchor rod and the panel. The 106 latch lock is made of engineering plastic, and insulating washers are added to the connection points to prevent the lock body from becoming a conductive medium.

[0047] The main bracket 100 has a reserved grounding terminal on the mounting panel 104. When high-voltage cables are installed, a grounding wire can be connected. In case of accidental leakage, the current will be conducted to the ground through the terminal, ensuring the safety of personnel and equipment.

[0048] The soft sheath of the roller 107 inside the clamping groove provides cushioning and reduces frictional damage during cable dragging. The limiting roller 103 cooperates with the roller 107 to prevent hard contact between the cable and the bracket, further reducing sidewall wear. The inner wall of the clamping groove is covered with a silicone rubber insulating pad with an anti-slip texture to prevent cable slippage during dragging and ensure laying stability. The modular design adapts to different scenarios, ultimately meeting the long-term stable installation requirements of cables at various corner positions.
