Description

Technical Field

[0001] This invention relates to the field of high-voltage power equipment technology, specifically a high-voltage equipment line clamp locking and fixing mechanism. Background Technology

[0002] In the field of high-voltage power equipment, the reliable fixing of long-span cables is a key link in ensuring the safe and stable operation of the power system. Existing high-voltage equipment clamp locking and fixing mechanisms typically employ a single or rigid mechanical structure, which mainly consists of a fixed support base and a pressing cover plate driven by a cylinder or bolts. The cable is placed between the base and the cover plate, and is fixed by a unidirectional downward pressing locking force; or, for longer spans, a fixed pulley guide structure is used for simple suspension and load-bearing.

[0003] However, under actual high-voltage, high-current, and strong vibration conditions, existing technical solutions have significant drawbacks. Long-span high-voltage cables are prone to significant deflection and sagging due to their own weight. Most existing fixing mechanisms are rigid structures with fixed heights, lacking dynamic lifting and lowering compensation capabilities. This not only easily leads to abnormal bending internal stress in the cable but also causes serious mechanical misalignment problems. Traditional clamps often use a single-point rigid contact clamping method, resulting in extremely concentrated force. In continuous strong vibration environments, not only does the locking force easily attenuate, causing cable slippage, but the single-point stress concentration also severely damages the cable insulation layer, shortening its service life. Summary of the Invention

[0004] The purpose of this invention is to provide a high-voltage equipment wire clamp locking and fixing mechanism to solve the problems mentioned in the background art.

[0020] As a further aspect of the present invention: both the first clamping plate and the second clamping plate have soft rubber teeth on their surfaces that are in contact with the cable. The hardness coefficient of the soft rubber teeth is less than that of the cable sheath, and they are used to generate frictional braking force on the cable through elastic deformation of the contact surface.

[0021] As a further embodiment of the present invention: the top of the guide limiting component is suspended and installed on the lifting frame by a hoisting frame;

[0022] The lifting frame is equipped with a lifting mounting frame;

[0023] The lifting drive component is fixed to the lifting mounting frame, and its drive end is connected to the hoisting frame, configured to drive the guide and limit assembly to move vertically.

[0024] As a further aspect of the present invention: the guide limiting component includes:

[0025] The hoisting frame has two support rollers arranged side by side at its bottom.

[0026] Rotatable steering sleeves are provided at both ends of each support roller;

[0027] A cable tray plate is installed between two opposing steering sleeves, the cable tray plate being located below the support roller and forming a guide gap between the support roller and the support roller for the cable to pass through.

[0028] As a further embodiment of the present invention: a belt drive component is provided along the side edge of the hoisting rail;

[0029] An extension rod extends outward from the outer edge of the steering sleeve, and a transmission gear set is connected between two adjacent extension rods.

[0030] The belt drive component is connected to the transmission gear set and is configured to synchronously drive the steering sleeves on both sides to rotate via the extension rod.

[0031] As a further aspect of the present invention: a base plate is provided below the cable tray plate, and a plurality of cable clamping posts are provided on the base plate through the cable tray plate body;

[0032] In the braking state, the rotation of the steering sleeve causes the cable support plate to undergo an eccentric flipping motion, which is configured to form a multi-point locking and fixing structure between the support roller, the cable support plate and the cable clamping post.

[0033] As a further aspect of the present invention: the support bracket includes:

[0034] The base plate has lifting adjustment blocks at both ends;

[0035] A support column is provided on the end fixed frame plate, and the lifting adjustment block passes through the support column to adjust the installation height of the support bracket;

[0036] A side support frame is installed on the lifting adjustment block. The top of the side support frame is provided with a connecting plate. A support platform for receiving cables led out from the guide limit assembly is erected between the two connecting plates.

[0037] As a further embodiment of the present invention: the position adjustment frame includes a fixed base and an adjustment frame fixed to the end fixed frame, the bottom of the fixed base is provided with a fixed mounting seat and a sliding seat, the bottom of the adjustment frame is provided with a sliding guide rail, and the sliding guide rail is sleeved on the sliding seat;

[0039] The pressing brake frame includes a pressing plate mounted on the adjusting frame via a folding hinge;

[0040] The adjustment frame is also equipped with a brake actuator. The pushing end of the brake actuator is connected to the folding hinge via a connecting push rod, and is configured to drive the pressing plate to fold downward and align and press with the supporting platform to re-fix the cable.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] This mechanism employs a three-stage linkage and multi-point locking design. At the front station, a stepped clamping section with soft rubber teeth applies progressive frictional damping to the cable, effectively preventing rigid damage and establishing initial braking. The centrally located guide and limit assembly has lifting and adjustment capabilities, dynamically adapting to the deflection deformation of the cable span. Its core eccentric flipping braking structure, driven by belt drive and gear components, causes the bracket to deflect at an angle, thereby driving the support rollers and locking pins to form a three-dimensional multi-point clamping, achieving zero-slip, powerful braking at high response speeds. The rear station features a bidirectional adjustment mechanism in both vertical and horizontal directions, precisely eliminating the risk of uneven wear caused by mechanical misalignment over long spans. A brake drives the pressing arm to flip downwards with a pressure of 2000 Newtons, forming a surface-contact rigid lock on the cable. The entire mechanism seamlessly integrates front-end flexible damping, mid-end eccentric clamping, and end-end rigid pressing, constructing a closed-loop control system of "front-damping and rear-locking."

[0043] This solution effectively disperses the stress points, significantly improving the fatigue life of the clamps under high voltage, high current, and strong vibration conditions, fundamentally ensuring the safety, stability, and long-term reliability of high voltage equipment cable fixing.

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, examples of which are illustrated in the drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or identical elements.

[0054] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0055] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0056] Example 1:

[0057] Reference Figure 1 This application provides a high-voltage equipment cable clamp locking and fixing mechanism. The overall structure of the mechanism is arranged in a long-stroke span, and its core frame includes a frame 1. The frame 1 is a horizontally extending rectangular frame structure. A drive box 11 is fixedly installed at one end of the frame along its length, and a load-bearing crossbeam 12 and an end fixing frame 13 are sequentially fixed at the other end of the frame along the cable transmission direction. The load-bearing crossbeam 12 and the end fixing frame 13 constitute the tail support and working area of ​​the entire mechanism, used to support the key locking components at the rear.

[0058] On the top of the drive housing 11, a wire assembly 3 is arranged facing forward. The wire assembly 3 serves as the initial guide port for external cables to enter the device. Furthermore, side supports 2 are symmetrically arranged on the left and right sides of the wire assembly 3. The side supports 2 are respectively installed on both sides of the support surface of the drive housing 11, and their main function is to serve as the physical support base for the clamping mechanism. On the side supports 2, along the path of cable input and forward transport, a first clamping part 4 and a second clamping part 5 are sequentially positioned and installed, arranged in a stepped manner.

[0059] In the middle section, a lifting frame 6 is fixedly mounted above the load-bearing beam 12. A guide and limiting component 7 is vertically and movably suspended at the bottom of the lifting frame 6. The guide and limiting component 7 functions to convert and guide the cable output from the front conductor assembly 3, ensuring its precise extension to the subsequent workstation. At the tail workstation, a support bracket 9 is fixedly mounted on the end fixed frame 13. The support bracket 9 is directly used to support the cable at a specific height. Simultaneously, within the area of ​​the end fixed frame 13 and the support bracket 9, a pressing brake frame 10 is centrally mounted in conjunction with the position adjustment frame 8. The pressing brake frame 10 is installed within the frame of the position adjustment frame 8 and can fold relative to the position adjustment frame 8.

[0060] The working process and overall technical effect of the high-voltage equipment wire clamp locking and fixing mechanism are as follows: The external power system cable is introduced through the conductor assembly 3 on the side of the drive box 11. When the cable passes through, it passes through the pilot clamp of the first clamping part 4 and the secondary pressing of the second clamping part 5 in sequence, forming a preliminary pre-braking and centering. Subsequently, the cable passes through the physical support of the guide limiting assembly 7 in the middle section, and is calibrated in the horizontal direction and height position. Finally, the cable passes through the frame of the position adjustment frame 8 and falls smoothly into the support slot of the support bracket 9. The pressing brake frame 10 presses down to lock the cable tightly in the support slot. The overall frame 1, as the core force carrier, organically integrates the "pre-position flexible pre-clamping" at the drive box 11, the "central floating guide" at the load-bearing crossbeam 12, and the "end rigid pressing" at the end fixing frame 13, to construct a multi-level linkage closed-loop fixing system with spatial self-adaptation capability, which comprehensively improves the locking stability and fatigue life of the equipment.

[0061] Example 2:

[0062] Based on Embodiment 1, this embodiment provides a detailed description of the detailed structure of the front guide assembly 3 and the specific implementation of the multi-level clamping chain. (Refer to...) Figure 1 and Figure 2 The conductor assembly 3 includes a guide plate 31 with a predetermined thickness and bending profile, which serves as the underlying physical guide structure for cable passage. An input guide block 33 is fixedly welded to the input side (i.e., the outward-facing starting end) of the guide plate 31, and an output guide block 32 is correspondingly fixed to the output side. Between the input guide block 33 and the output guide block 32, a transition channel 34 is recessed along the length of the guide plate 31. This transition channel 34 is generally shaped like a cable guide groove, with an arc-shaped cross-section. A cover plate 36 is fastened to the upper part of the transition channel 34 by screws. A wire-passing hole 35 is machined through the center of the cover plate 36 and communicates with the transition channel 34. The external cable slides in through the front opening of the input guide block 33, proceeds steadily along the curved profile of the transition channel 34, and finally exits precisely through the wire-passing hole 35, then connects to the guide limiting assembly 7.

[0063] Side brackets 2 are vertically installed on the left and right sides of the guide plate 31. A fixed bracket 41 is bolted to the vertical wall of the side bracket 2, and a clamping arm 42 is horizontally installed on the fixed bracket 41. The clamping arm 42 is L-shaped, and its free end is fixedly connected to a first clamping plate 43. The clamping surface of the first clamping plate 43 is directly close to the entrance end of the cover plate 36, i.e., located immediately outside the cable hole 35. Meanwhile, an additional set of side-mounted supports 51 is provided on the side edge of the guide plate 31, located behind the clamping arm 42 (with the cable forward direction as the front). A section of outwardly extending pressing arm 52 is vertically installed on the upper part of the side-mounted support 51, and a second clamping plate 53 is fixedly installed at the suspended end of the pressing arm 52. The second clamping plate 53 is located at the leading edge of the first clamping plate 43 along the cable conveying direction, and the two together form a physical two-stage pressing gap.

[0064] In a preferred embodiment, to achieve efficient braking while avoiding damage to the cable, soft rubber teeth are embedded on the clamping surfaces of both the first clamping plate 43 and the second clamping plate 53. The soft rubber teeth are made of elastic rubber or polyurethane material, with a material ratio that controls the Shore hardness of the teeth to be within the range of 45 to 55A, and its overall hardness coefficient to be 10% to 15% lower than the hardness of the cable sheath. According to multiple sets of actual tensile test data, under a pre-clamping thrust of 50 to 100 Newtons, the coefficient of friction of the soft rubber teeth can be maintained above 0.8. In actual operation, when the cable passes through the soft rubber teeth of the first clamping plate 43, the soft rubber teeth can generate a frictional braking effect through surface contact using elastic deformation, initially providing a stable damping force of about 60 Newtons to prevent the cable from generating torsional stress or backing up during long strokes. Immediately afterwards, the second clamping plate 53, located at the leading edge, performs secondary auxiliary pressing, providing secondary damping of about 100 Newtons, forming a pre-braking effect with an early "backing up" function. Through this step-by-step progressive clamping chain from loose to tight, the potential deformation hazards caused by external mechanical traction forces on the cable sheath of power equipment are effectively eliminated.

[0065] Example 3:

[0066] This embodiment focuses on a detailed description of the eccentric tilting braking structure formed by the lifting frame 6 and the guide limiting assembly 7. (Refer to...) Figure 3 , Figure 4 and Figure 5 The lifting frame 6 is securely mounted on the load-bearing beam 12. A hoisting frame 61 is fixedly welded to the top of the guide limiting assembly 7. The hoisting frame 61 passes through the internal space of the lifting frame 6 and is suspended below the lifting frame 6 by hoisting. A lifting mounting frame 63 is also fixedly installed inside the lifting frame 6. The lifting mounting frame 63 serves as the base for the drive component, on which a vertically arranged lifting drive component 62 is mounted. The lifting drive component 62 can be in the form of a servo motor or cylinder. The drive end of its piston rod or lead screw is fixedly connected to the top seat of the hoisting frame 61. Through the extension and retraction of the lifting drive component 62, the guide limiting assembly 7 is pushed to move vertically. In a preferred embodiment, the active stroke range of the lifting drive component 62 is set to 100 to 200 mm, which is sufficient to accommodate the deflection changes of different specifications of cables due to gravity between spans, and prevents oblique pulling through dynamic adjustment.

[0067] Observing the core structure of the guide and limiting assembly 7, the main body below it is the lifting rail 71. Two parallel support rollers 72 are arranged side-by-side at the bottom end of the lifting rail 71. Each support roller 72 is cylindrical, with a rotatable steering sleeve 73 concentrically fitted at both ends. At the radial connection between the two opposing steering sleeves 73, a long strip-shaped cable support plate 74 is fixedly mounted. The cable support plate 74 is located directly below the support rollers 72, with a gap of 1.5 to 2 mm between it and the support rollers 72, forming the initial guide channel for the cable to pass through smoothly. Directly below the cable support plate 74, a base plate 76 is fixedly installed, parallel to the cable support plate 74. On the top surface of the base plate 76, several wire-clamping posts 75 are arranged in an array. The wire-clamping posts 75 pass vertically upward through the plate body of the cable tray plate 74. The top of each wire-clamping post 75 is rounded and chamfered, and its length is slightly higher than the upper surface of the cable tray plate 74.

[0068] Regarding its transmission power chain, a belt drive component 77 is installed on the outer wall of the side edge of the hoisting frame 71. The belt drive component 77 is preferably a synchronous belt pulley assembly. Extending rods 78 extending laterally are welded outwards at equal angles around the outer edge of the steering sleeve 73. Adjacent extending rods 78 are linked together by a transmission gear set 79, which uses a bevel gear system for 90-degree transmission reversal. When braking and locking operations are required, the working process is as follows: the external controller sends a braking signal, the belt drive component 77 starts and instantly outputs driving force. The belt drive component 77 drives the transmission gear set 79 to enter a synchronous rotation state via the synchronous belt. The rotation of the transmission gear set 79 causes the extending rods 78 on both sides to produce synchronous angular displacement, thereby forcibly driving the steering sleeves 73 at both ends to rotate synchronously around the axis of the support roller 72. Because the cable support plate 74 is suspended below the support roller 72, as the steering sleeve 73 deflects clockwise or counterclockwise, the cable support plate 74 will undergo angular displacement around the support roller 72 as its axis, forming an "eccentric linkage flipping" physical phenomenon. This eccentric flipping process directly causes the effective gap between the top of the cable clamping post 75 and the lower edge of the support roller 72 to decrease rapidly from a loose gap of 3 mm to zero contact. Combined with dynamic torque testing, the mechanical response time of the belt drive component 77 is less than 0.5 seconds. When the cable support plate 74 is folded into place, the local contact pressure of the cable between the support roller 72 and the cable clamping post 75 can be stably controlled at 10 to 15 MPa. This eccentric flipping-based structural design ensures that each cable is tightly engaged between the support roller 72, the cable support plate 74, and the cable clamping post 75, forming a three-dimensional multi-point engaging structure. This significantly enhances the single-point impact braking torque resistance and truly achieves slip-free rapid locking under high-pressure conditions.

[0069] Example 4:

[0070] This embodiment details the locking system consisting of the position adjustment frame 8, the support bracket 9, and the pressing brake frame 10. (Refer to...) Figure 5 and Figure 6 The support bracket 9 has a horizontally placed base plate 91 at its bottom. Each end of the base plate 91 has a U-shaped notch, and a pair of lifting adjustment blocks 93 are fitted into the notches. Four support columns 92 are vertically fixed to both sides of the end fixing frame 13. The lifting adjustment blocks 93 are fitted onto the columns of the support columns 92 and can slide up and down within the sliding groove along the height of the column. A side support frame 94 is bolted to the base of the lifting adjustment block 93. The side support frame 94 extends upwards, and a connecting plate 95 is horizontally installed at its top corner. A U-shaped support platform 96 with an upward-facing opening is bolted between two symmetrically distributed connecting plates 95. The opening depth of the support platform 96 matches the outer diameter of the cable. In operation, the cable passing through the gap between the cable tray plate 74 and the support roller 72 of the guide limiting assembly 7 and hanging down will be smoothly and accurately guided into the U-shaped groove of the support platform 96.

[0071] To achieve precise positioning of long-span cables and overcome wear caused by material processing and installation errors, this embodiment introduces a bidirectional adjustment mechanism. The position adjustment frame 8 includes a fixed base 81 and a hollow adjustment frame 84. The bottom of the fixed base 81 is anchored to the top surface of the end fixed frame 13, and a fixed mounting seat 86 is fixedly installed at the center of the bottom of the plate. The fixed mounting seat 86 has a horizontal adjustment rod 85 inside. T-shaped sliding guide rails 82 are formed on both sides of the bottom of the adjustment frame 84. Two sliding seats 83 are fixed parallel to the surface of the fixed base 81, and the sliding guide rails 82 pass directly through and slide into the sliding seats 83. The drive rod end of the fixed mounting seat 86 is connected to the horizontal adjustment rod 85, and the horizontal adjustment rod 85 is fixedly connected to the sliding guide rail 82. Therefore, when the operator rotates the horizontal adjustment rod 85, it can push the sliding guide rail 82 to move laterally back and forth in the sliding seat 83, thereby driving the entire adjustment frame 84 to move in the horizontal direction (Y-axis). With the aforementioned lifting adjustment block 93 providing vertical fine-tuning on the support column 92, this mechanism achieves precise spatial alignment capabilities of ±20 mm vertically (Z-axis) and ±30 mm horizontally (Y-axis). This bidirectional adaptive adjustment mechanism ensures absolute physical alignment between the support platform 96 and the rear cable input from the guide limit component 7, fundamentally preventing high-frequency vibration and uneven wear caused by mechanical misalignment.

[0072] After spatial positioning is completed, the pressing brake frame 10 undertakes the final high-tension locking task. The pressing brake frame 10 includes a pressing plate 101, the back of which is mounted on the top edge of the adjusting frame 84 via a folding hinge 102, and the pressing plate 101 can be rotated 90 degrees around the pivot of the folding hinge 102. A brake actuator 104 is fixedly arranged in the inner cavity of the adjusting frame 84, preferably a high-thrust hydraulic push rod or a high-torque motor-driven lead screw. The lateral pushing end of the brake actuator 104 is connected to a connecting push rod 103 via a spherical bearing, and the other lateral end of the connecting push rod 103 is hinged to the crank end of the folding hinge 102. When final cable locking is required, the controller instructs the brake actuator 104 to extend forward. Its push rod, through the connecting push rod 103, applies torque to the folding hinge 102, forcing the folding hinge 102 to engage in locking action, causing the pressing plate 101 to fold downwards at a rapid speed. According to stress calculations in actual engineering, under the vibration conditions of high-current, high-voltage equipment, the pressing force provided by the brake actuator 104 is preferably set to 2000 to 3000 Newtons. This thrust acts on the pressing plate 101 and tightly presses it against the groove surface of the support platform 96, generating a locking pressure of approximately 6 to 8 MPa. At this time, a surface-contact rigid pressing fixation is formed between the pressing plate 101 and the support platform 96. This rear-mounted rigid pressing, in close cooperation with the front-mounted flexible friction brake in Embodiment 2, constitutes a "front-blocking, rear-locking" physical defense line, ultimately achieving multi-point, multi-directional tension locking. After multiple rounds of high-frequency fatigue testing, thanks to the scientific distribution of stress points in this structure, the overall clamp mechanism can effectively extend its service life by more than 30% compared to conventional single-point locking structures under high voltage and high current environments, demonstrating outstanding practicality and safety stability.
