Description

Technical Field

[0001] This invention relates to the field of cable installation technology, specifically to a modular cable splicing assembly. Background Technology

[0002] In infrastructure sectors such as power transmission and communication network construction, cable laying is a crucial link in ensuring the stable transmission of energy and information. Currently, cable laying operations mainly rely on traditional support structures. However, with the surge in demand for large-scale construction projects such as urban power grid upgrades, rural electrification transformation, and 5G communication networks, traditional cable laying components are gradually revealing many insurmountable technical defects. For example, traditional cable erection supports are mostly integral welded structures, and their installation positions and load-bearing capacity are fixed at the factory. When new cable lines need to be added on the same utility pole, since the original supports do not have reserved installation interfaces, construction workers need to remove the original supports and re-weld them or drill additional holes in the utility pole to install new supports. This not only increases the workload of construction, but may also damage the structural integrity of the utility pole. Meanwhile, the integral bracket cannot adapt to the needs of cable layout with different spacing and number, and its adaptability is extremely poor in the scenario of multiple lines being laid in parallel. Therefore, a modular cable laying splicing component is proposed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a modular cable laying splicing assembly to address the significant deficiencies in flexibility, adaptability, stability, and operability of current traditional cable laying assemblies mentioned in the background art, which can no longer meet the needs of efficient, flexible, and safe cable laying in modern infrastructure construction.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A modular cable laying splicing assembly includes an installation device, a mounting device, and a clamping device. The installation device includes a utility pole and a fixing frame. The fixing frame is symmetrically welded to the utility pole. The mounting device is installed on the fixing frame, and the clamping device is installed on the mounting device. An installation groove is opened laterally in the middle of the fixing frame, and the mounting device is hung into the installation groove through the opening.

[0005] The mounting device includes a suspension rod and a cross rod. When installing the suspension rod, one end is vertically clamped into the mounting groove. The lower part of the suspension rod is sleeved with the cross rod. A clamping device is provided on one side of the cross rod, and support devices for supporting the cable are symmetrically provided on both sides of the cross rod.

[0006] The clamping device includes two mounting plates, upper and lower, with clamping plates on opposite sides of the two mounting plates and arc-shaped surfaces on opposite sides of the clamping plates; a movable cavity is opened on the mounting plate, the clamping plates are inserted into the movable cavity, a support spring is arranged diagonally between the clamping plates and the movable cavity, and a damping rod is installed between the middle of the clamping plate and the movable cavity.

[0007] Preferably, the fixing frame is a U-shaped plate with the opening facing downwards, and a fixing rod is provided in the mounting groove. One end of the fixing rod is welded to the side of the mounting groove closest to the utility pole. The fixing rod is the same length as the fixing frame, and the end of the fixing frame away from the utility pole is provided with an opening.

[0008] Preferably, the upper part of the suspension rod has a through-hole for mounting, the fixing rod is inserted into the mounting hole, the top of the fixing frame is equipped with a dovetail bolt, the dovetail bolt is screwed down through the fixing rod and the suspension rod for fixing, and multiple mounting devices are installed in the fixing frame; the cross bar is provided with a dovetail bolt for fixing on the side away from the clamping device.

[0009] Preferably, the supporting device includes a fixing bolt and a supporting wheel. The fixing bolt is threaded through and screwed onto both sides of the cross rod, and the supporting wheel is installed at the other end of the fixing bolt. A fixing shaft is provided in the middle of the supporting wheel, and a threaded groove is opened in the middle of the fixing shaft. The fixing bolt is threaded through and screwed into the threaded groove. The main body of the supporting wheel is rolled on the outside of the fixing shaft. After installation, the supporting wheel rolls on the fixing shaft. The supporting wheel is located on both sides of the clamping device.

[0010] Preferably, the mounting plate is provided with nuts on the side away from the cross bar, and the inner cavity of the mounting plate is provided with screw holes near the nuts.

[0011] The two mounting plates are symmetrically distributed on the upper and lower sides of the cross rod. The dovetail bolts used to fix the cross rod and the suspension rod extend through the screw holes to the nuts, thus fixing the mounting plates and the cross rod together.

[0012] Preferably, the damping rod includes a damping cylinder and a connecting rod. The damping cylinder is fixed on the side of the movable cavity away from the clamping plate. A damping spring is provided inside the damping cylinder. A connecting rod extending outward is provided at the end of the damping spring near the clamping plate. An abutment is provided at the end of the connecting rod near the clamping plate. The abutment is attached to the clamping plate.

[0013] The connecting rod extends and retracts synchronously with the clamping plate, achieving dynamic energy absorption through the action of the damping spring; the abutment joint is flared to increase the contact area with the clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This solution achieves modular splicing through the modular design of the installation device, mounting device, and clamping device, which greatly improves the flexibility and scalability of the installation.

[0015] The mounting bracket of the installation device adopts a U-shaped structure with mounting slots. The mounting devices can be directly hung into the mounting slots through the openings, and multiple mounting devices can be installed in the bracket. Construction personnel can flexibly increase or decrease the number of mounting devices according to the number of cable lines without secondary modifications to the bracket or utility poles, adapting to single-line and multi-line parallel installation scenarios. At the same time, the mounting devices are doubly secured by fixing rods and dovetail bolts, ensuring both installation stability and quick disassembly and replacement to meet the needs of future line adjustments.

[0016] The clamping device's clamping plate is elastically supported by a support spring and a damping rod, and the clamping plate can flexibly extend and retract along the movable cavity of the mounting plate. When clamping cables of different diameters, the clamping plate automatically conforms to the outer wall of the cable under the elastic force of the support spring. The arc-shaped surface design further increases the contact area with the cable, enabling stable clamping of cables of different diameters within a certain range without the need to replace clamping components, significantly reducing accessory costs and construction complexity.

[0017] The symmetrical support devices on both sides of the cross bar have support rollers that can roll and support the cables on both sides of the clamping device, transferring part of the cable's weight to the support rollers and reducing the load on the clamping device. At the same time, the support rollers can roll freely with the thermal expansion and contraction or slight displacement of the cable, avoiding static friction between the cable and the support components, reducing the risk of wear on the cable sheath, and extending the cable's service life.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0027] Please see Figure 1-7 The present invention provides the following technical solution: A modular cable laying splicing assembly includes an installation device 100, a mounting device 200, and a clamping device 300. The installation device 100 includes a utility pole 101 and a fixing frame 102. The fixing frame 102 is symmetrically welded to the utility pole 101. The mounting device 200 is installed on the fixing frame 102, and the clamping device 300 is installed on the mounting device 200.

[0028] The mounting bracket 102 is a U-shaped plate with the opening facing downwards. A mounting groove 103 is horizontally opened in the middle of the mounting bracket 102. A fixing rod 104 is installed in the mounting groove 103. One end of the fixing rod 104 is welded to the side of the mounting groove 103 near the utility pole 101. The fixing rod 104 is the same length as the mounting bracket 102, and the end of the mounting bracket 102 away from the utility pole 101 is provided with an opening. The hanging device 200 is hung in the mounting groove 103 through the opening.

[0029] The mounting device 200 includes a suspension rod 201 and a cross rod 202. The upper part of the suspension rod 201 has a through mounting hole 203. When installing the suspension rod 201, one end is vertically snapped into the mounting groove 103, and the fixing rod 104 is inserted into the mounting hole 203, so that the suspension rod 201 is stably suspended and supported. The top of the fixing frame 102 is equipped with a dovetail bolt. The dovetail bolt passes through and screws the fixing rod 104 and the suspension rod 201 in sequence. The suspension rod 201 is fixed together with the fixing frame 102 by the dovetail bolt. Multiple mounting devices 200 can be installed in the fixing frame 102.

[0030] A cross rod 202 is sleeved on the lower part of the suspension rod 201. A clamping device 300 is provided on one side of the cross rod 202. A dovetail bolt for fixing is provided on the side of the cross rod 202 away from the clamping device 300 to fix the cross rod 202 to the suspension rod 201. Supporting devices are symmetrically provided on both sides of the cross rod 202. The supporting devices include fixing bolts 204 and supporting wheels 205. The fixing bolts 204 are threaded through and screwed to both sides of the cross rod 202, and the supporting wheels 205 are installed on the other end of the fixing bolts 204.

[0031] A fixed shaft is provided in the middle of the support roller 205. A threaded groove is opened in the middle of the fixed shaft. The fixing bolt 204 is threaded through and screwed into the threaded groove. The main body of the support roller 205 is rolled on the outside of the fixed shaft. The support roller 205 is located on both sides of the clamping device 300 and is used to support the cables on both sides of the clamping device 300. After installation, the support roller 205 can roll on the fixed shaft.

[0032] The clamping device 300 includes two mounting plates 301, one above the other. Each mounting plate 301 has a nut 302 on the side away from the cross rod 202, and a screw hole is opened in the inner cavity of the mounting plate 301 near the nut 302. The two mounting plates 301 are symmetrically distributed on the upper and lower sides of the cross rod 202. The dovetail bolts used to fix the cross rod 202 and the suspension rod 201 extend through the screw hole to the nut 302, thus fixing the mounting plate 301 and the cross rod 202 together.

[0033] Clamping plates 303 are provided on opposite sides of the two mounting plates 301. The opposite sides of the clamping plates 303 are provided with arc-shaped surfaces for clamping cables. The mounting plates 301 have movable cavities, and the clamping plates 303 are inserted into the movable cavities. Supporting springs 304 are provided diagonally between the clamping plates 303 and the movable cavities. A damping rod 305 is installed between the middle of the clamping plates 303 and the movable cavities to provide elastic support for the clamping plates 303.

[0034] The clamp 303 can flexibly adapt to cables of different diameters through elastic support, and the clamp 303 has an elastic buffer function to reduce vibration caused by cable swaying.

[0035] The damping rod 305 includes a damping cylinder 3051 and a connecting rod 3053. The damping cylinder 3051 is fixed on the side of the movable cavity away from the clamping plate 303. A damping spring 3052 is provided inside the damping cylinder 3051. A connecting rod 3053 extending outward is provided at the end of the damping spring 3052 near the clamping plate 303. An abutment 3054 is provided at the end of the connecting rod 3053 near the clamping plate 303. The abutment 3054 is attached to the clamping plate 303.

[0036] The connecting rod 3053 extends and retracts synchronously with the clamping plate 303, and achieves dynamic energy absorption through the action of the damping spring 3052, effectively converting the force on the clamping plate 303; the abutment 3054 is flared to increase the contact area with the clamping plate 303.

[0037] The clamping device 300 is provided with a limiting buckle 306 on the outside. The limiting buckle 306 includes two buckle plates, which are symmetrically installed on the upper and lower mounting plates 301. The upper buckle plate is rotatably provided with a limiting rod. The limiting rod is located vertically on the outside of the cable to prevent the cable from being clamped by the clamping device 300.

[0038] A limiting push plate 307 is slidably installed on the outer wall of the lower buckle. When the limiting push plate 307 hangs down in its natural state, the bottom of the limiting rod is engaged with the position of the lower buckle. Then the limiting push plate 307 falls down and blocks the bottom outside of the limiting rod to prevent the limiting rod from rebounding outward. Pushing the limiting push plate 307 upward will release the restriction on the limiting rod, and the limiting rod can rotate normally.

[0039] Modular cable laying and splicing components achieve stable cable laying and flexible splicing through the coordinated action of installation devices, mounting devices, and clamping devices.

[0040] The mounting device serves as the base for the entire assembly, its core function being to stably secure the assembly to the utility pole and provide a standardized installation interface for the mounting equipment. The mounting bracket employs a U-shaped plate structure with the opening facing downwards, rigidly connected to the utility pole via symmetrical welding to form a stable support base. A ring-shaped metal clamp is installed between the mounting bracket and the utility pole, serving as a welding base and providing a solid foundation for subsequent module installation.

[0041] A horizontal mounting groove is opened in the middle of the fixing frame, and a fixing rod of the same length as the fixing frame is welded in the groove. The fixing rod serves as a suspension fulcrum for the mounting device and also limits the lateral sway of the mounting device through structural design. At the same time, an opening is reserved at the end of the fixing frame away from the utility pole. This opening serves as the installation entrance for the mounting device, which can be quickly attached to the mounting device and can be assembled without disassembling the fixing frame.

[0042] The mounting slot structure of the mounting bracket supports the parallel installation of multiple mounting devices. They can be hung sequentially along the length of the mounting rod, meeting the needs of simultaneous installation of multiple sets of cables and demonstrating the modularity and scalability of the components.

[0043] The mounting device is the intermediate hub connecting the installation device and the clamping device. It has the dual functions of suspension and cable support. The upper part of the suspension rod of the mounting device has a mounting hole. During installation, one end of the suspension rod is vertically inserted into the mounting groove of the fixing frame, so that the fixing rod is inserted into the mounting hole to achieve the initial positioning of the suspension rod. Then, the fixing rod and the suspension rod are rigidly locked by the dovetail bolts on the top of the fixing frame, which completely prevents the suspension rod from moving up and down or left and right.

[0044] A cross bar is sleeved at the lower part of the suspension rod. The cross bar can slide along the height direction of the suspension rod. After being adjusted to a suitable position, it is locked by the dovetail bolt on the side of the cross bar away from the clamping device, thereby realizing the height adjustment of the clamping device. At the same time, the cross bar provides an installation platform for the clamping device, ensuring that the clamping device is vertically aligned with the suspension rod.

[0045] Supporting devices are symmetrically installed on both sides of the crossbar. The supporting wheels are fixed to the crossbar by the cooperation of the fixing bolts and screw grooves, and the main body of the supporting wheel can roll freely around the fixed axis. The supporting wheels are located on both sides of the clamping device. Their function is to support the cables on both sides of the clamping device, so as to avoid the cable weight being entirely borne by the clamping device and to distribute the load. In addition, when the cable expands and contracts due to temperature changes or is pulled slightly by external force, the rolling characteristics of the supporting wheels can reduce the friction between the cable and the components and protect the cable sheath from wear.

[0046] The clamping device is the core component that directly contacts and fixes the cable, achieving elastic clamping and vibration buffering, ensuring adaptability and stability for cables of different diameters.

[0047] The upper and lower mounting plates of the clamping device are symmetrically distributed on the upper and lower sides of the cross rod. The mounting plate has screw holes in its inner cavity. The dovetail bolts used to fix the cross rod and the suspension rod can pass through the screw holes and be screwed to the nuts on the outside, which rigidly fixes the mounting plate and the cross rod, so that the clamping device and the hanging device form an integrated structure and prevent the clamping device from shaking independently.

[0048] Clamping plates are installed on opposite sides of the mounting plate, and these clamping plates are inserted into the movable cavity of the mounting plate. Support springs are arranged diagonally between the clamping plates and the movable cavity, and a damping rod is installed in the middle. When the cable is placed between the two clamping plates, the support springs push the clamping plates toward the cable through their own elastic deformation, and the preload of the springs achieves initial clamping of the cable.

[0049] The opposite sides of the clamp are designed with arc surfaces to fit the circular cross-section of the cable, increasing the contact area and preventing damage to the cable from excessive local pressure. The elasticity of the support spring allows the clamp to flexibly adapt to cables of different diameters. It can be adapted to various specifications without replacing the clamp, and has the versatility of cable clamping.

[0050] When the cable sways due to factors such as wind or passing vehicles, the clamp plate experiences a reverse force from the cable. At this time, the damping rod and support spring work together to buffer the movement. The damping rod consists of a damping cylinder, a damping spring, a connecting rod, and an abutment. The damping cylinder is fixed inside the movable cavity. One end of the connecting rod is connected to the clamp plate, and the other end extends into the damping cylinder and contacts the damping spring. When the clamp plate moves inwards towards the movable cavity under force, the connecting rod compresses the damping spring, which absorbs vibration energy through elastic deformation.

[0051] The diagonal arrangement of the support springs can decompose the lateral / longitudinal forces on the clamping plate, avoiding excessive force in one direction. At the same time, the dynamic energy absorption characteristics of the damping rod can convert the kinetic energy of vibration into the elastic potential energy of the spring, and then release it slowly through damping, effectively reducing the impact of cable swaying on the components and preventing fatigue damage to the cable caused by long-term vibration. The damping rod's abutment joint is designed in a flared shape, which can increase the contact area with the clamping plate, ensure uniform force transmission, and avoid local deformation of the clamping plate.

[0052] A limiting buckle is installed on the outside of the clamping device. The mechanical locking structure prevents the cable from falling out of the clamping range due to violent shaking or accidental external force, further improving the safety of cable installation. The upper and lower buckle plates of the limiting buckle are respectively installed on the upper and lower mounting plates. The upper buckle plate is rotatably connected to the limiting rod. After the cable is clamped, the limiting rod is rotated so that it is vertically positioned outside the cable, and the bottom of the limiting rod is inserted into the slot of the lower buckle plate. At this time, the limiting rod forms a protective barrier to prevent the cable from falling outward.

[0053] A limiting push plate is slidably installed on the outer wall of the lower buckle plate. In its natural state, the limiting push plate hangs down due to gravity. When the bottom of the limiting rod is engaged with the lower buckle plate, the limiting push plate falls downward and is blocked on the outside of the bottom of the limiting rod, forming a reverse blockage and achieving secondary locking.

[0054] When it is necessary to inspect or replace the cable, simply push the limit plate upward to disengage it from the blocking position at the bottom of the limit rod, and then rotate the limit rod to open the protection. No tools are required for operation, which combines safety and convenience.

[0055] The above description is merely a specific embodiment of the present invention, and the various examples do not constitute a limitation on the substantive content of the present invention.
