Description

Technical Field

[0001] This invention relates to the field of cable installation device technology, and more specifically to a universal parallel groove clamp adjustable mounting rod. Background Technology

[0002] In power line connection, inspection, and maintenance operations, the parallel trench clamp, as a core component for conductor connection and branching, directly determines the reliability and continuity of power grid operation based on its installation quality. Especially for county-level users, the work scenarios present significant unique challenges: the geographical coverage is vast, and work sites are often distributed across complex terrains such as farmland, forests, low-lying areas, and hillsides, making it difficult for large equipment like insulated bucket trucks to reach the work areas. Conventional installation tools are also limited by the terrain. As a result, operators are often forced to adopt a power outage work mode, which not only paralyzes the regional power grid and triggers numerous user complaints but also seriously affects power supply reliability. Simultaneously, due to the lack of suitable long-distance operating tools, workers must climb to the top of concrete poles to perform high-altitude work, facing immense physical challenges. Prolonged high-altitude work also easily leads to fatigue, significantly increasing the safety hazards of falls and electric shocks, posing a serious threat to the personal safety of the workers. In addition, the existing parallel groove clamp installation method has many inherent drawbacks: First, there are many specifications and types of parallel groove clamps, and the existing installation tools are mostly special-purpose and have poor versatility. Corresponding tools need to be equipped for different specifications of clamps, which increases the construction cost and the burden of carrying tools; Second, there is a lack of dedicated positioning and clamping mechanisms. When manually positioning the parallel groove clamp and the conductor, it is easy for them to deviate or twist, resulting in poor contact and causing safety hazards such as overheating and burning; Third, the operation mode of manually clamping the conductor and the clamp at the same time is labor-intensive, has low installation efficiency, and the installation accuracy depends on the experience of the operators, making it difficult to ensure the consistency of construction. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a universal adjustable mounting rod for parallel groove clamps, which can effectively solve the problems in the prior art.

[0004] This invention provides a universal adjustable mounting rod for parallel groove clamps, including a mounting rod. The top end of the mounting rod is connected and fixed to a working platform via a mounting plate. Both sides of the top end of the working platform are vertically fixed with protruding plates. Two sets of parallel groove clamp fixing devices and wire clamping devices are symmetrically fixed to the top end of the working platform. Each set of parallel groove clamp fixing devices includes an L-shaped plate fixed to the top end of the working platform, a T-shaped plate inserted inside the L-shaped plate, pins inserted on the upper and lower sides of the T-shaped plate, and a spring sleeved on the outside of the pins. A mounting plate is sleeved on the outside of the pins. The two ends of the spring are connected and fixed to the T-shaped plate and the mounting plate, respectively. Side grooves are formed on both sides of the working platform. The wire clamping device includes a clamping block, a fixing rod fixed in the side groove, and a torsion spring sleeved on the outside of the fixing rod. A limit bolt is engaged and fixed in the middle of the protruding plate.

[0005] Furthermore, the mounting plate is fixedly connected to the working platform by multiple sets of bolts.

[0006] Furthermore, the L-shaped plate has an inner groove in the middle, the T-shaped plate is inserted horizontally into the inner groove, and the upper and lower sides of the T-shaped plate are both provided with circular holes, the end of the pin is inserted into the circular holes.

[0007] Furthermore, the mounting plate is fixed to the top of the mounting rod, and the protruding plate and the working platform are combined to form an L-shape.

[0008] Furthermore, the clamping block is crescent-shaped, and a threaded hole is provided in the middle of the convex plate, and the limiting bolt is engaged and fixed in the threaded hole.

[0009] Furthermore, this device can be used in conjunction with an electric tightening wrench.

[0010] Compared with existing technologies, the beneficial effects of this invention are as follows: Based on the installation pole structure design, operators do not need to climb concrete poles and can complete remote installation operations on the ground or in safe areas. It perfectly adapts to complex terrains such as farmland, forests, and hillsides, effectively solving the pain points of large equipment being inaccessible and high-altitude operations being risky. Simultaneously, the precise positioning and clamping function avoids line faults caused by improper operation in traditional operations, supports live-line working modes, completely eliminates power grid paralysis caused by power outage operations, reduces user complaints, and ensures the continuity and reliability of power supply.

[0011] In this device, the combined action of the parallel groove clamp fixing device and the wire clamping device eliminates the need for manual handling of both components simultaneously, significantly reducing physical exertion and alleviating the physical challenges for operators. The ground operation mode completely avoids safety hazards such as falls from heights and electric shocks. The addition of an electric tightening wrench further enhances the ease of operation, making the work process safer and more efficient, and providing strong protection for the personal safety of operators.

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

[0016] The present invention will be further described below with reference to embodiments.

[0017] Example: Universal parallel groove clamp adjustable mounting rod, see attached document. Figure 1 -Appendix Figure 4The device includes an installation rod 1, the top of which is connected and fixed to a working platform 2 via an installation plate 11. Both sides of the top of the working platform 2 are vertically fixed with protruding plates 21. Two sets of parallel groove clamp fixing devices 3 and wire clamping devices 4 are symmetrically fixed to the top of the working platform 2. Based on the structural design of the installation rod 1, this device allows operators to perform long-distance installation operations on the ground or in a safe area without climbing concrete poles. It is perfectly adaptable to complex terrains such as farmland, forests, and hillsides, effectively solving the pain points of large equipment being inaccessible and high-altitude operations being risky. Simultaneously, the precise positioning and clamping function avoids line faults caused by improper operation in traditional operations, supports live-line working mode, completely eliminates power grid paralysis caused by power outage operations, reduces user complaints, and ensures the continuity and reliability of power supply.

[0018] Each set of parallel groove clamp fixing device 3 includes an L-shaped plate 31 fixed to the top of the working platform 2, a T-shaped plate 32 inserted inside the L-shaped plate 31, a pin 33 inserted on the upper and lower sides of the T-shaped plate 32, and a spring 34 sleeved on the outside of the pin 33. An mounting piece 35 is sleeved on the outside of the pin 33. The two ends of the spring 34 are connected and fixed to the T-shaped plate 32 and the mounting piece 35 respectively. Side grooves 22 are opened on both sides of the working platform 2. The wire clamping device 4 includes a clamping block 41, a fixing rod 42 fixed in the side groove 22, and a torsion spring 43 sleeved on the outside of the fixing rod 42. A limit bolt 44 is engaged and fixed in the middle of the convex plate 21. The mounting plate 11 is fixed to the working platform 2 by multiple sets of bolts. The convex plate 21 and the working platform 2 are combined to form a stable L-shaped structure with strong overall load-bearing capacity. It can withstand the fastening force in complex working environments and is not easily deformed. All components are made of high-quality materials, with reliable connections, strong wear resistance, and long service life. It can adapt to the high-frequency operation requirements of complex terrain in counties for a long time and meets the design concept of reliable performance and quality. Mounting plate 11 is fixedly connected to working platform 2 by multiple sets of bolts; mounting plate 11 is fixed to the top of mounting rod 1, and the protruding plate 21 and working platform 2 are combined to form an L-shape; The L-shaped plate 31 has an inner groove 311 in the middle, and the T-shaped plate 32 is inserted horizontally into the inner groove 311. The upper and lower sides of the T-shaped plate 32 are both through-holes, and the end of the pin 33 is inserted into the hole. The adjustable structure design allows the T-shaped plate to slide flexibly along the inner groove 311 of the L-shaped plate. With the elastic clamping structure of the pin 33 and the spring 34, it can accurately adapt to different specifications of parallel groove wire clamps. The crescent-shaped clamping block 41 can automatically fit wires of different diameters under the action of the torsion spring 43, realizing "one tool for multiple purposes". It completely solves the problem of poor versatility of existing tools, reduces the types and number of tools to carry, reduces construction costs, and improves operational flexibility.

[0019] The clamping block 41 is crescent-shaped, and a threaded hole is opened in the middle of the protruding plate 21. The limiting bolt 44 is engaged and fixed in the threaded hole. Through the threaded connection, rotating the limiting bolt 44 moves linearly, simultaneously pushing the clamping block 41 to close, thereby pressing the wire and fixing it in the groove of the parallel groove clamp. The standardized positioning and clamping structure avoids problems such as wire misalignment and wire clamp loosening, ensuring that the parallel groove clamp and the wire are tightly fitted, significantly improving installation accuracy and reducing safety hazards caused by poor contact. The device is easy to assemble and disassemble, and can be quickly tightened with an electric tightening wrench. Compared with traditional manual operation, it greatly shortens the installation time. At the same time, the standardized operation process ensures installation consistency, avoids inconsistent quality caused by differences in human experience, and comprehensively improves construction quality and efficiency.

[0020] This device is used in conjunction with an electric tightening wrench, which can be operated remotely from the ground via a remote control handle. The electric wrench provides high torque output for more efficient tightening. By changing the socket, different sizes of bolts can be tightened. It is securely connected to the mounting rod, easy to disassemble, occupies little space, and is easy to carry. The base of the parallel groove clamp fits snugly against the working platform 2. By compressing the spring 34, the contact distance between the T-block 32 and the parallel groove clamp is adjusted to fix different models of parallel groove clamps. For new and old lines, the conductor cross-sections are different, and the conductors may be stiff or at a certain angle due to weather and the initial installation angle of the conductors, making it difficult to operate when connecting two conductors. When personnel install parallel groove clamps, they may bump into the conductors, causing the clamp opening to change and making it difficult to insert the conductor properly. Using the conductor clamping device 4, one end of the conductor is first fixed in the groove clamp slot, and the conductor is clamped by the device, forcing the base of the parallel groove clamp to be fixed and preventing it from moving up and down, thus fixing the opening of the parallel groove clamp.

[0021] The device, through the synergistic action of the parallel groove clamp fixing device 3 and the wire clamping device 4, eliminates the need for manual handling of both components simultaneously, significantly reducing physical exertion and alleviating the physical challenges for operators. The ground operation mode completely avoids safety hazards such as falls from heights and electric shocks, and the addition of an electric tightening wrench further enhances ease of operation, making the operation process safer and more efficient, and providing strong protection for the personal safety of operators.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
