Description

Technical Field

[0001] This invention relates to the field of power transmission line connection device technology, and in particular to a parallel trench clamp installation device. Background Technology

[0002] Parallel groove clamps are widely used conductor connection hardware in power transmission and distribution systems. They are mainly used to electrically and mechanically connect two or more parallel conductors to ensure stable and reliable current transmission between them. Parallel groove clamps typically use bolts to press the upper and lower plates together, applying clamping force to the conductors to achieve low contact resistance and good mechanical strength. The quality of their installation directly affects the safety and reliability of the line operation.

[0003] In existing technologies, to meet the requirements of current carrying capacity and mechanical strength, parallel groove clamps mostly adopt a double-bolt or multi-bolt symmetrical fastening structure. In actual installation operations, construction workers typically need to use tools such as insulated operating rods and wrenches to tighten the bolts of the parallel groove clamps. Because parallel groove clamps are often located in high-altitude, energized, or near-energized environments, installation space is limited, making operation difficult, and the bolt tightening process requires high levels of synchronization and uniform force distribution. For example, patent application CN119182033B, entitled "An Operating Rod for Installing Parallel Groove Clamps," discloses a method that uses a tool body at the end of an insulated rod, combined with a limiting rod and a sliding V-shaped cone structure, to achieve functions such as positioning, lead wire locking, and opening of the upper and lower clamps during installation. This solution simplifies the rod-mounting and initial positioning operations of the parallel groove clamps to a certain extent, reduces the operational burden on construction workers, and has certain practical value.

[0004] However, the aforementioned technical solutions and most existing parallel groove clamp installation devices primarily focus on clamping, positioning, or temporary fixation of the clamps. The crucial bolt tightening process in parallel groove clamps still generally relies on manual labor or a single drive method for individual tightening. In parallel groove clamps with a double-bolt structure, if alternating or sequential tightening methods are used, asynchronous force on both sides is highly likely to occur. This can lead to excessive force on one bolt while the other side is not yet fully engaged, resulting in potential problems such as thread stripping, bolt misalignment, uneven force on the clamp plate, and even damage to the clamp itself, severely affecting connection quality and service life. Furthermore, when dealing with parallel groove clamps of different specifications and bolt spacings, existing installation devices, due to the fixed spacing between the two bolt sleeves of the tightening component, cannot adapt to parallel groove clamps with different bolt spacings. This often requires changing to different types of tools or manually adjusting the operation method to complete the installation, which not only reduces work efficiency but also increases the complexity and safety risks of on-site operations. Summary of the Invention

[0005] The technical problem to be solved by this invention is: to solve the problem that the parallel groove clamp installation device cannot be adapted to parallel groove clamps with different bolt spacings.

The first end of the first rotating rod passes through the second through hole and is rotatably mounted on the rotating hole. The second end of the first rotating rod is provided with a first bevel gear. The two sides of the first bevel gear are respectively meshed with two second bevel gears.

[0007] Furthermore, the top and bottom of the slider are provided with sliding holes, and there are two sliding rods, which are located above and below the second through hole, respectively, and the two sliding rods pass through the sliding hole at the top of the slider and the sliding hole at the bottom of the slider, respectively.

[0008] Furthermore, it also includes a damping rod, the two ends of which are connected to the fixed plate and the slider respectively. The damping rod is located between the two sliders, and the first spring is sleeved on the slider.

[0009] Furthermore, it also includes a wire clamp mounting frame, which has a through groove. The clamp assembly is disposed in the through groove, and the inner sidewall of the through groove has a first guide rod. The first guide rod extends from the inner sidewall of the through groove to the other inner sidewall of the through groove, and the first clamping plate is slidably disposed on the first guide rod.

[0010] Furthermore, the first clamping plate includes a clamping plate, a second spring, a limiting rod, and a push plate. The push plate has a sliding through hole on its side. The push plate is slidably mounted on the first guide rod along the sliding through hole. The first end of the limiting rod is connected to the side of the clamping plate, and the second end of the limiting rod passes through the side of the push plate. The second spring is sleeved on the limiting rod, and both ends of the second spring are connected to the push plate and the clamping plate, respectively. The first through hole passes through the clamping plate and the push plate. The connecting plate is located on the side of the push plate away from the clamping plate.

[0011] Furthermore, the clamping assembly also includes a second clamping plate disposed opposite to the first clamping plate. The second clamping plate is disposed on the other inner sidewall of the through groove. The other inner sidewall of the through groove is provided with a second guide rod. The second guide rod extends from the other inner sidewall of the through groove toward the inner sidewall of the through groove. The second clamping plate is slidably disposed on the second guide rod.

[0012] Furthermore, it also includes a second electric push rod, which is disposed on the bottom of the through groove. The top of the second electric push rod is provided with a base plate and two connecting arms disposed on the base plate. The bottom of the first clamping plate and the second clamping plate are both provided with a first rotating shaft. The top surface of the base plate is provided with two second rotating shafts. The two ends of the connecting arms are rotatably connected to the first rotating shaft and the second rotating shaft respectively.

[0013] Furthermore, the top surface of the base plate is provided with two guide plates, each guide plate having a mounting groove, and the clamp assembly is located between the two guide plates.

[0015] Furthermore, it also includes a second operating lever, the top of which is provided with a monkey head locking lever head, and the bottom of which is provided with a monkey head control handle. The monkey head locking lever head and the through groove are located at the same horizontal level.

[0016] Compared with the prior art, the parallel groove clamp installation device of this invention has the following advantages: By setting a first clamping plate in the clamping assembly, the parallel groove clamp is stably clamped and positioned, effectively avoiding clamp shaking or displacement during installation; at the same time, the tightening assembly, through the synchronous meshing transmission structure of the first bevel gear on the first rotating rod and the second bevel gears on both sides, enables the two sets of threaded sleeves to rotate in the same direction and synchronously during driving, thereby enabling synchronous tightening of the bolts on both sides of the parallel groove clamp, significantly improving the problems of uneven force, bolt misalignment or stripping that are easily caused by the traditional individual tightening method, and improving the consistency and reliability of the tightening process; in addition, by setting a directional... The sliding block, in conjunction with the compressed first spring, ensures that the threaded sleeve remains well aligned with the bolt axis. Simultaneously, the first electric push rod of the push assembly adjusts the position of the first bevel gear, causing its tooth surface to generate a controllable lateral pressure with the tooth surface of the second bevel gear. This, in turn, drives the first bevel gear to smoothly slide the slider along the sliding block, achieving dynamic adjustment of the distance between the two sets of threaded sleeves. Utilizing the coordinated mechanism of gear meshing and slider sliding, the threaded sleeve can adjust its position according to the actual bolt spacing of the parallel groove clamp, enabling adaptive adjustment for parallel groove clamps with different bolt spacings. This further enhances the device's adaptability to bolt distances of parallel groove clamps of different specifications. Attached Figure Description

[0019] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0020] like Figures 1 to 11As shown in the figure, an embodiment of the present invention discloses a parallel grooved wire clamp installation device, including: a clamp assembly 2, the clamp assembly 2 having a first clamping plate 21, the first clamping plate 21 having a first through hole 201, the first clamping plate 21 being used to clamp the parallel grooved wire clamp; and a tightening assembly 3, the tightening assembly 3 including a connecting plate 31, a sliding rod 33, two fixing plates 32 and two sliders 34, the connecting plate 31 being disposed on the outer side of the first clamping plate 21, the side of the connecting plate 31 having a second through hole 301 corresponding to the first through hole 201, the fixing plates 32 being disposed on the connecting plate 31, the sliding rod 33 being disposed between the two fixing plates 32, the sliders 34 being slidably disposed on the sliding rod 33, the sliders 34 having a third through hole 302 and a second rotating part being rotatably disposed in the third through hole 302. The rod 341 has a threaded sleeve 342 and a second bevel gear 343 at both ends. The threaded sleeve 342 is located at the first through hole 201. A first spring 35 in a compressed state is provided between the slider 34 and the fixed plate 32. The pushing assembly 4 includes a connecting plate 44 with a rotating hole 401 on the side, a first rotating rod 42 and a first electric push rod 41. The two ends of the first electric push rod 41 are connected to the connecting plate 44 and the connecting plate 31, respectively. The first end of the first rotating rod 42 passes through the second through hole 301 and is rotatably mounted on the rotating hole 401. The second end of the first rotating rod 42 is provided with a first bevel gear 411. The two sides of the first bevel gear 411 are respectively engaged with two second bevel gears 343.

[0021] The parallel groove clamp installation device of this application provides stable clamping and positioning of the parallel groove clamp through the first clamping plate 21 set in the clamping assembly 2, effectively preventing the clamp from shaking or shifting during installation. Simultaneously, the tightening assembly 3, through the synchronous meshing transmission structure of the first bevel gear 411 on the first rotating rod 42 and the second bevel gears 343 on both sides, enables the two sets of threaded sleeves 342 to rotate in the same direction and synchronously during driving. This allows for the synchronous tightening of the bolts on both sides of the parallel groove clamp, significantly improving problems such as uneven force distribution, bolt misalignment, or stripping that are easily caused by traditional individual tightening methods, thus enhancing the consistency and reliability of the tightening process. Furthermore, by setting a slider 34 that can slide along the sliding rod 33 and cooperate with the compressed state... The first spring 35, while ensuring that the threaded sleeve 342 is always well aligned with the bolt axis, adjusts the position of the first bevel gear 411 through the first electric push rod 41 of the tightening assembly 3, so that its tooth surface generates a controllable lateral extrusion force with the tooth surface of the second bevel gear 343, thereby pushing the first bevel gear 411 to drive the slider 34 to slide smoothly along the slide rod 33, realizing the dynamic adjustment of the distance between the two sets of threaded sleeves 342. By utilizing the coordination mechanism of gear meshing and slider 34 sliding, the threaded sleeve 342 can adjust its position according to the actual bolt spacing of the parallel groove clamp, and can realize the adaptive adjustment of parallel groove clamps with different bolt spacings, further enhancing the device's ability to adapt to the bolt distance of parallel groove clamps of different specifications.

[0022] By adjusting the position of the first bevel gear 411 by pushing the first electric push rod 41 of component 4, its teeth can exert a lateral squeezing force on the tooth surface of the second bevel gear 343, thereby pushing the first bevel gear 411 to drive the slider 34 to slide along the slide rod 33. When the first electric push rod 41 pushes the first bevel gear 411 closer to the second bevel gear 343, the lateral squeezing force exerted by the teeth of the first bevel gear 411 on the tooth surface of the second bevel gear 343 increases, causing the slider 34 to slide away from the first bevel gear 411 under the influence of the second bevel gear 343, thereby increasing the distance between the two sliders 34 and increasing the distance between the threaded sleeves 342 on the two sliders 34; when the first electric push rod 41 pushes the first bevel gear 411 away from the second bevel gear 343, the teeth of the first bevel gear 411 exert a lateral squeezing force on the tooth surface of the second bevel gear 343, thereby pushing the slider 34 to slide away from the first bevel gear 311. The tooth surface of the bevel gear 343 generates less lateral compressive force, causing the slider 34 to slide closer to the first bevel gear 411, driven by the first spring 35 between the slider 34 and the fixed plate 32. This reduces the distance between the two sliders 34, thereby reducing the spacing between the threaded sleeves 342 on the two sliders 34. This allows for flexible adjustment of the spacing between the two sets of threaded sleeves 342, enabling it to adapt to different spacing of parallel groove clamp bolt configurations. This structure significantly enhances the adaptability of the parallel groove clamp installation device to parallel groove clamps of different specifications, improving the versatility and efficiency of parallel groove clamp installation.

[0023] Specifically, an electric motor 43 is provided on the side of the connecting plate 44 away from the connecting disc 31, and the electric motor 43 is used to drive the first rotating rod 42 to rotate. A limiting block is provided in the middle of the sliding rod 33 to restrict the movement of the slider 34, thereby keeping the slider 34 in a suitable sliding range and preventing the second bevel gear 343 from moving to a position where it cannot mesh with the first bevel gear 411. The first clamping plate 21 and the second clamping plate 22 are provided with clamping grooves for clamping and threading the wire clamp. It should be noted that the outer side of the first clamping plate 21 refers to the side of the first clamping plate 21 away from the second clamping plate 22.

[0024] Specifically, the outer side of the first clamping plate 21 is provided with an annular groove, and the connecting plate 31 is provided with a sliding block adapted to the annular groove. The connecting plate 31 is slidably mounted on the first clamping plate 21 via the sliding block. The sliding block is provided with a limiting plate inserted into the annular groove to prevent the connecting plate 31 from sliding off the annular groove. Alternatively, the connecting plate 31 can be mounted on the outer side of the first clamping plate 21 by multiple annularly arranged positioning bolts. By loosening the positioning bolts, the connecting plate 31 can be rotated as a whole, thereby changing the layout direction of the two sets of threaded sleeves 342, so that it can adapt to bolt configurations with different arrangements, such as transverse or longitudinal. This structure greatly enhances the tool's adaptability to different specifications of parallel groove clamps, improving the versatility and efficiency of operation.

[0025] It should be noted that the slider 34 is slidably mounted on the slide rod 33, but is not limited to being mounted on the slide rod 33. The slider 34 can also be slidably mounted on structures such as slide rails, racks, and transmission belts to facilitate the movement of the slider 34 along its length.

[0026] like Figure 3 and Figure 6 As shown, in an optional embodiment of the present invention, the top and bottom of the slider 34 are provided with sliding holes 303, and there are two sliders 33. The two sliders 33 are located above the second through hole 301 and below the second through hole 301, respectively. The two sliders 33 pass through the sliding holes 303 at the top and bottom of the slider 34, respectively.

[0027] By providing sliding holes 303 at both the top and bottom of the slider 34, and arranging two sliding rods 33 above and below the second through hole 301 respectively, the slider 34 forms a double-guided constraint structure during sliding, thereby significantly improving the guiding accuracy and motion stability of the slider 34 when moving along the sliding rods 33, effectively avoiding the shaking, skewness, or jamming phenomena that are prone to occur under a single guiding structure. Through the cooperation of the double sliding rods 33 and the double sliding holes 303, when the threaded sleeve 342 applies tightening force to the grooved wire clamp bolt, the lateral load generated by the bevel gear meshing and the bolt reaction force can be evenly distributed, ensuring that the slider 34 always maintains good coaxiality with the bolt axis, thereby improving the centering and force consistency during synchronous tightening, reducing the risk of thread wear and wear of transmission components, and further improving the reliability, durability, and overall operational stability of the grooved wire clamp installation device under high load conditions.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment of the present invention, the parallel groove clamp installation device of this application further includes a damping rod 6. The two ends of the damping rod 6 are respectively connected to the fixing plate 32 and the slider 34. The damping rod 6 is located between two sliding rods 33, and the first spring 35 is sleeved on the sliding rod 33.

[0029] By setting a damping rod 6 between the fixed plate 32 and the slider 34, and placing the damping rod 6 between the two sliding rods 33, the slider 34 is simultaneously constrained by the elastic restoring force and the damping buffer force during its movement along the sliding rods 33 and under force. The damping rod 6 can effectively suppress and absorb the vibration or shaking generated by the first spring 35 or the slider 34, ensuring that the slider 34 quickly stabilizes in the new position. Thus, when the threaded sleeve 342 synchronously tightens or adjusts the spacing of the parallel groove clamp bolts, it effectively suppresses the instantaneous impact, vibration and rebound of the slider 34, significantly improving the smoothness and controllability of the sliding process. At the same time, the first spring 35 is sleeved on the sliding rod 33, forming an elastic damping composite buffer structure with the damping rod 6. This not only provides a stable adaptive adjustment capability when the spacing of parallel groove clamp bolts of different specifications changes, but also effectively releases the reaction force of the transmission system at the end of tightening, avoiding gear meshing instability or sudden changes in thread force due to sudden load. This further improves the reliability of the synchronous tightening process, the structural durability and the safety of the parallel groove clamp installation operation.

[0030] Specifically, there are multiple first electric push rods 41, which are arranged in a circular array around the second through hole 301.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, the parallel groove clamp installation device of this application further includes a clamp installation frame 1. The clamp installation frame 1 is provided with a through groove 101. The clamp assembly 2 is disposed in the through groove 101. The inner side wall of the through groove 101 is provided with a first guide rod 11. The first guide rod 11 extends from the inner side wall of the through groove 101 to the other inner side wall of the through groove 101. The first clamping plate 21 is slidably disposed on the first guide rod 11.

[0032] By setting a through groove 101 inside the online clamp mounting frame 1 and arranging the clamp assembly 2 entirely inside the through groove 101, the parallel groove clamp can be effectively confined within the internal space of the frame during installation, structurally reducing the impact of external interference on the clamp's posture. Simultaneously, a first guide rod 11 is set on the inner wall of the through groove 101, and the first clamping plate 21 slides linearly along the first guide rod 11, while the second clamping plate 22 is fixed to the other inner wall of the through groove 101. This creates a clear and stable unidirectional guiding and opposing clamping relationship when clamping the parallel groove clamp, ensuring that the first clamping plate 21 always smoothly approaches the parallel groove clamp in a predetermined direction during force application, avoiding uneven clamping due to offset or tilt. This structure not only improves the centering and stability of the parallel groove clamp during clamping and tightening but also makes the clamping force path clearer and more controllable, effectively preventing the clamp from rotating or shifting when tightening bolts, further enhancing the reliability, safety, and structural rigidity of the parallel groove clamp installation operation.

[0033] like Figure 2 , Figure 7 and Figure 8 As shown, in an optional embodiment of the present invention, the first clamping plate 21 includes a clamping plate 211, a second spring 212, a limiting rod 213, and a push plate 214. The push plate 214 has a sliding through hole on its side and is slidably mounted on the first guide rod 11 along the sliding through hole. The first end of the limiting rod 213 is connected to the side of the clamping plate 211, and the second end of the limiting rod 213 passes through the side of the push plate 214. The second spring 212 is sleeved on the limiting rod 213 and its two ends are respectively connected to the push plate 214 and the clamping plate 211. The first through hole 201 passes through the clamping plate 211 and the push plate 214. The connecting plate 31 is disposed on the side of the push plate 214 away from the clamping plate 211.

[0034] By configuring the first clamping plate 21 as an elastic composite clamping structure consisting of a clamping plate 211, a push plate 214, a limiting rod 213, and a second spring 212, the clamping process is transformed from rigid contact to an elastic clamping form with buffering and adaptive capabilities. The push plate 214 slides stably along the first guide rod 11 through a sliding through-hole and maintains axial alignment with the clamping plate 211 under the constraint of the limiting rod 213, thus achieving linear propulsion with controllable force direction and stable movement path when clamping the wire clamp. The second spring 212 is sleeved on the limiting rod 213, forming an elastic force between the push plate 214 and the clamping plate 211. The connection not only automatically compensates for positional deviations caused by differences in the size, tolerance, or installation posture of the parallel groove clamps during clamping, but also flexibly adjusts the clamping force when the bolts are tightened synchronously, avoiding local stress concentration or damage to the clamp surface caused by rigid clamping. At the same time, the first through hole 201 penetrates the clamp plate 211 and the push plate 214, and the connecting plate 31 is set on the outside of the push plate 214, so that the bolt tightening transmission and clamping functions are structurally separated yet work together, further improving the centering stability, clamping reliability, and adaptability and operational safety of the entire parallel groove clamp installation device under complex working conditions.

[0035] like Figure 2 and Figure 9 As shown, in an optional embodiment of the present invention, the clamp assembly 2 is further provided with a second clamp 22 disposed opposite to the first clamp 21. The second clamp 22 is disposed on another inner side wall of the through groove 101. The other inner side wall of the through groove 101 is provided with a second guide rod 12. The second guide rod 12 extends from the other inner side wall of the through groove 101 toward the inner side wall of the through groove 101. The second clamp 22 is slidably disposed on the second guide rod 12.

[0036] By setting a second guide rod 12 on the other inner wall of the through groove 101 and making the second clamping plate 22 slide linearly along the second guide rod 12, the originally fixed second clamping plate 22 is transformed into a movable clamping structure with guiding constraints. This upgrades the parallel groove clamp in the through groove 101 from a single-sided active clamping to a double-sided opposing and adjustable clamping method. This structure ensures that both the first clamping plate 21 and the second clamping plate 22 are linearly constrained by the guide rod during the clamping process, and can move towards the parallel groove clamp synchronously and parallelly. This effectively avoids uneven clamping and force eccentricity caused by single-sided clamping or clamping plate posture deviation. At the same time, the double guide clamping plate structure is conducive to continuously providing symmetrical and stable clamping force to the parallel groove clamp during the synchronous tightening of bolts, significantly improving the centering and anti-displacement ability of the clamp, reducing the risk of torsion or slippage during tightening, and thus further improving the stability, reliability and overall installation quality of the parallel groove clamp installation device under high-altitude or confined space operation conditions.

[0037] Specifically, the first clamping plate 21 has a sliding through hole on its side so as to be slidably mounted on the first guide rod 11, and the second clamping plate 22 has a sliding through hole on its side so as to be slidably mounted on the second guide rod 12.

[0038] like Figure 3 and Figure 10 As shown, in an optional embodiment of the present invention, the parallel groove clamp installation device of this application further includes a second electric push rod 7. The second electric push rod 7 is disposed on the bottom of the through groove 101. The top of the second electric push rod 7 is provided with a base plate 71 and two connecting arms 72 disposed on the base plate 71. The bottom of the first clamping plate 21 and the second clamping plate 22 are both provided with a first rotating shaft 23. The top surface of the base plate 71 is provided with two second rotating shafts 73. The two ends of the connecting arms 72 are rotatably connected to the first rotating shaft 23 and the second rotating shaft 73 respectively.

[0039] By setting a second electric push rod 7 at the bottom of the through groove 101, and using the base plate 71 and the paired connecting arms 72 to form a rotational connection with the first rotating shaft 23 at the bottom of the first clamping plate 21 and the second clamping plate 22, and the second rotating shaft 73 on the base plate 71 respectively, the linear extension and retraction motion of the second electric push rod 7 can be synchronously converted into opposing clamping or releasing actions on the first clamping plate 21 and the second clamping plate 22, thereby realizing the linkage drive and synchronous movement of the clamping plates on both sides. This structure avoids the problem of asynchronous clamping caused by relying on unilateral drive or manual adjustment in the traditional method, so that the parallel groove clamp always maintains a centered state and symmetrical force during the clamping and bolt tightening process, effectively preventing the clamp from tilting, rotating or slipping during the force process. At the same time, the use of the hinged transmission form of the rotating shaft and the connecting arm 72 can automatically compensate for small installation errors during the movement of the clamping plates, reduce the risk of mechanism jamming, and make the clamping action more stable and reliable, further improving the automation level, operational stability and overall installation safety and consistency of the parallel groove clamp installation device.

[0040] like Figure 2 , Figure 3 and Figure 10 As shown, in an optional embodiment of the present invention, the top surface of the base plate 71 is provided with two guide plates 74, the guide plates 74 are provided with mounting grooves 701, and the clamp assembly 2 is located between the two guide plates 74.

[0041] By setting two conductor plates 74 on the top surface of the base plate 71 and forming mounting grooves 701 on the conductor plates 74 to accommodate the conductors, the parallel groove clamp and the conductors to be connected have clear spatial limits and support benchmarks during installation. This effectively guides the conductors into the clamping area of ​​the parallel groove clamp at a predetermined position, preventing the conductors from shifting, crossing, or misaligning due to their own weight or external forces. At the same time, the clamp assembly 2 is arranged between the two conductor plates 74, so that the conductors, parallel groove clamps, and clamping mechanisms form a relatively fixed assembly relationship within the same spatial frame. This helps to maintain the relative position stability of the conductors and clamps during the clamping of the plates and the synchronous tightening of the bolts, thereby reducing the risk of uneven clamping or poor contact caused by changes in the position of the conductors. This structure further improves the centering and overall stability of the parallel groove clamp during installation, reduces the need for manual adjustment, and significantly improves the installation efficiency, safety, and final connection quality under high-altitude or live-line working conditions.

[0042] like Figure 1 , Figure 3 and Figure 11 As shown, in an optional embodiment of the present invention, the bottom surface of the wire clamp mounting frame 1 is provided with a first operating lever 13. The first end of the second electric push rod 7 passes through the bottom of the through groove 101 and is connected to the bottom surface of the base plate 71. The second end of the second electric push rod 7 extends through the first operating lever 13. The first operating lever 13 is provided with a lithium battery that provides power to the second electric push rod 7 and a control button 131 that controls the push of the second electric push rod 7. The second electric push rod 7 is electrically connected to the lithium battery and the control button 131 respectively. The top end of the second electric push rod 7 is provided with a connecting shaft. The first end of the connecting shaft passes through the bottom of the through groove 101 and is connected to the bottom surface of the base plate 71.

[0043] A first operating lever 13 is installed on the bottom surface of the online clamping frame 1, and the drive end, power supply and control system of the second electric push rod 7 are integrated inside the first operating lever 13. This allows the clamping and releasing actions of the clamping assembly 2 to be centrally controlled through a single operating lever, significantly simplifying the operation process during the installation of the parallel groove clamp. Specifically, the lithium battery and control button 131 are integrated into the first operating lever 13, which can provide stable power to the second electric push rod 7 and achieve instant and precise control of the advance stroke. This allows construction personnel to complete the opposing clamping adjustment of the clamp plate without frequent replacement or external power equipment in high-altitude or live working environments, improving the convenience and safety of the operation. At the same time, the second electric push rod 7 forms a stable axial force transmission path with the base plate 71 through the connecting shaft, and passes through the bottom of the through groove 101 and the internal space of the operating lever, making the thrust transmission more direct and reliable, reducing structural loosening or energy loss, and further improving the response consistency of the clamping action and the integration and reliability of the overall device.

[0044] like Figure 1 As shown, in an optional embodiment of the present invention, the parallel groove clamp installation device of the present application further includes a second operating lever 5. The top of the second operating lever 5 is provided with a monkey head lock rod head 51, and the bottom of the second operating lever 5 is provided with a monkey head control handle 52. The monkey head lock rod head 51 and the through groove 101 are located at the same horizontal height.

[0045] By setting a monkey-head locking rod head 51 at the top and a monkey-head control handle 52 at the bottom of the second operating rod 5, construction personnel can flexibly operate the entire installation device with one or both hands, achieving precise positioning of the parallel groove clamp within the through groove 101 and simultaneous clamping and bolt tightening operations. Operators can remotely control the monkey-head locking rod head 51 to firmly lock the wire and smoothly guide it to the preset position within the clamp mounting frame 1 of the parallel groove clamp installation device. Simultaneously, the control button 131 on the second operating rod 5 can conveniently activate the clamp assembly 2 and bolt tightening components, thereby automating the connection and fastening operations between the wire and the parallel groove clamp, achieving efficient and safe live or de-energized wiring operations. The operating lever of the parallel groove clamp and lead wire of this application not only improves the grip stability and ease of operation of the operating lever in high-altitude, live, or confined space operations, but also enables quick locking or releasing of the installation device, thereby significantly shortening the installation cycle and reducing the labor intensity and safety risks of operators; at the same time, through effective integration with the installation device, the second operating lever 5 can achieve flexible operation and safe handling of parallel groove clamps of different specifications while maintaining the alignment and clamping stability of the conductor and clamp, further enhancing the versatility, reliability, and on-site operation efficiency of the overall installation system.

[0046] The parallel groove wire clamp installation device provided in this application includes a clamp assembly 2 on a wire clamp installation frame 1. The clamp assembly 2 includes a first clamping plate 21 and a second clamping plate 22 arranged opposite to each other. The first clamping plate 21 has a first through hole 201. The first clamping plate 21 and the second clamping plate 22 are used together to clamp the parallel groove wire clamp. A connecting plate 31 is fixedly installed on the side of the first clamping plate 21 away from the second clamping plate 22. The side of the connecting plate 31 has a second through hole 301. A connecting plate 44 is installed on the connecting plate 31. The side of the connecting plate 44 has a rotating hole 401, a first rotating rod 42, and a first electric push rod 41. The two ends of the first electric push rod 41 are connected to the connecting plate 44 and the connecting plate 31, respectively. The first end of the first rotating rod 42 passes through the second through hole 301 on the connecting plate 31 and is rotatably mounted on the rotating hole 401 of the connecting plate 44. The second end of the first rotating rod 42 has a first bevel gear 411. Two fixing plates 32 are also provided on the connecting plate 31. The two fixing plates 32 are located on both sides of the second through hole 301. A slide rod 33 is installed between the fixing plates 32. Two sliders 34 are slidably mounted on the slide rod 33. Each slider 34 is provided with a third through hole 302 and is rotatably equipped with a second rotating rod 341. The two ends of the second rotating rod 341 are respectively provided with a threaded sleeve 342 and a second bevel gear 343. The two second bevel gears 343 are respectively meshed with the two sides of the first bevel gear 411. The threaded sleeve 342 is located at the first through hole 201 so as to correspond to the bolt of the parallel groove clamp. At the same time, the first spring 35 is kept in a compressed state between the slider 34 and the fixing plate 32.

[0047] During use, the first electric push rod 41 drives the first rotating rod 42 and the first bevel gear 411 to rotate, causing the second bevel gear 343, which meshes with it, to rotate synchronously. This drives the slider 34 and the threaded sleeve 342 to simultaneously tighten the parallel groove clamp bolts, ensuring that the bolts on both sides are subjected to uniform force and tightened consistently. At the same time, the first clamping plate 21 and the second clamping plate 22 of the clamp assembly 2 can apply symmetrical and stable clamping force to the parallel groove clamp, maintaining the clamp's positioning and centering during tightening and preventing the clamp from shifting or tilting. The slider 34 slides smoothly along a predetermined trajectory on the slide rod 33, and the first spring 35 provides appropriate elastic buffering, ensuring that the threaded sleeve 342 maintains good coaxiality when meshing with the bolt and automatically compensates for slight gaps or tolerance differences, thereby improving the reliability of synchronous tightening and the overall operational stability. With the above structure, this embodiment can not only adapt to different specifications of parallel groove clamp bolt spacing, but also improve installation efficiency and ensure connection quality under high-altitude or confined space operation conditions, while significantly reducing the complexity of manual operation and potential safety risks.
