Description

Technical Field

[0001] This invention belongs to the field of wire clamp connection installation technology, specifically relating to a non-standard parallel groove wire clamp connection installation fixture, installation method and installation device. Background Technology

[0002] The performance of various types of parallel trench clamps, which are numerous in urban and rural power grids, directly affects the reliability of actual power supply. Currently, all parallel trench clamps are non-load-bearing, generally including three types: bolt-type parallel trench clamps, H-type (or C-type) parallel trench clamps, and wedge-type parallel trench clamps. The irregular parallel trench clamp discussed in this article is one type of bolt-type parallel trench clamp. It uses the tightening pressure of bolts and nuts to press the upper and lower clamps together, thereby fixing the main and auxiliary lines in the corresponding guide grooves between the upper and lower clamps. Traditionally, the installation of irregular parallel trench clamps is mostly done manually using insulated bucket trucks or insulated platforms to access live conductors. This not only exposes workers to direct contact with live conductors, increasing safety risks, but also involves high operational difficulty, numerous steps, low efficiency, and the working environment is easily affected by the local geographical environment.

[0003] Clearly, given the current situation where live-line contact work involves a wide variety of insulating tools and poor manual operation, developing a specialized, easy-to-operate, functionally integrated, and highly automated non-standard parallel groove clamp installation device is crucial for promoting standardized procedures, simplified processes, digitalized process monitoring, intelligent tools, and ensuring worker safety in live-line contact work. However, the following issues still need to be addressed in developing such a device: Firstly, non-standard parallel groove clamps have an irregular structure, significantly different in appearance from other clamps, and are used in high-altitude environments. How to reliably lock, position, and even release these non-standard parallel groove clamps without affecting installation remains a challenge. On the other hand, when installing the non-standard parallel groove clamp, the auxiliary line needs to be installed first, and the main line is then snapped together. However, the opening size of the main line clamping port formed by the upper and lower clamping plates before and after clamping the auxiliary line is small, which is not conducive to quickly aligning the main line and achieving convenient snap-in operation, and this needs to be solved urgently. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a non-standard parallel groove wire clamp installation fixture to provide a basic working platform for wire clamp installation under high-altitude mechanical operations. This invention can ensure the smooth operation of reliable locking, positioning and even release of non-standard parallel groove wire clamps, thereby effectively improving the efficiency of parallel groove wire clamp operation. The overall structure is also extremely compact and stable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-standard parallel groove wire clamp installation fixture is characterized by: an installation groove plate with the groove facing upwards, into which the wire clamp can be inserted along the vertical groove length direction; an installation opening is provided at the bottom of the groove plate for the nut end of the fastening bolt of the wire clamp to protrude; a top block is arranged on at least one side of the groove wall of the installation groove plate, the top block generates an upward lifting action of supporting the lower edge of the upper clamp plate through a vertical lifting part, and is driven by a horizontal lateral movement part to generate a horizontal forward and backward movement relative to the side wall of the wire clamp; notches are provided on both sides of the installation groove plate to avoid the installation path of the main line and the auxiliary line, and a positioning part is provided at the notch for the auxiliary line to pass through to press the auxiliary line into the guide groove of the lower clamp plate from top to bottom.

[0007] Preferably, a left fixed frame is arranged on the left side wall of the mounting slot plate. The vertical lifting part includes a vertical guide rail fixed on the vertical frame and a vertical slider that is fitted on the vertical guide rail. The vertical slider always produces a vertical upward reset action through a vertical elastic part. The vertical slider and the top block are fixed to each other. The horizontal traversing part includes a left-end horizontal guide rod. The left-end horizontal guide rod and the left fixed frame form a horizontal guide rail sliding fit. The inner end of the left-end horizontal guide rod is fixed on the vertical frame, so that it can drive the vertical lifting part to produce a horizontal traversing action. The outer end of the left-end horizontal guide rod constitutes the operating end. A left-end horizontal elastic part is provided at the left-end horizontal guide rod, so that the left-end horizontal elastic part always drives the vertical lifting part and the top block to produce a horizontal inward elastic reset action. The lower edge of the end of the top block that is used to fit the side wall of the wire clamp is provided with a lower chamfer.

[0008] Preferably, both the vertical elastic part and the left-end horizontal elastic part are compression springs; the vertical elastic part is sleeved on the vertical guide rail, and the top end of the vertical elastic part abuts against the bottom end of the vertical slider from bottom to top, while the bottom end of the vertical elastic part abuts against the bottom wall of the vertical frame; the left-end horizontal elastic part is sleeved on the left-end horizontal guide rod, and the inner end of the left-end horizontal elastic part abuts against the outer wall of the vertical frame, while the outer end of the left-end horizontal elastic part abuts against the inner wall of the left fixed frame.

[0009] Preferably, a through hole is provided on the left fixed frame so that a horizontal connecting rod can pass through, and the vertical slider and the top block are fixed at both ends of the horizontal connecting rod respectively; the inner end of the through hole is recessed with a receiving opening for accommodating the top block.

[0010] Preferably, the receiving opening is shaped like an inverted "L", and the top block is shaped like an L-shaped block that matches the outline of the shoulder of the receiving opening. The L-shaped opening of the top block and the shoulder of the receiving opening form a limiting fit that restricts the maximum downward distance of the top block.

[0011] Preferably, the top surface of the top block is an upwardly sloping wedge-shaped structure, and the highest point of the top surface forms a mating end that mates with the front end surface of the top block; the contour of the bent surface formed by the top surface and the front end surface matches the contour of the inner bend on the side of the lower plate of the upper clamping plate near the main line clamping opening.

[0012] Preferably, the fixture includes a main line guide fork and a secondary line guide fork extending obliquely upward along the two ends of the mounting slot plate; the positioning part includes a secondary line pressure rod horizontally hinged to the top of the secondary line guide fork, and the secondary line pressure rod is connected to the piston rod end of the drive cylinder through a drive linkage.

[0013] Preferably, the axis of the drive cylinder is vertically fixed at the mounting slot; one end of the drive connecting rod is fixed to the outer side of the auxiliary line guide fork, and the other end of the drive connecting rod is horizontally hinged to the top of the arc rod, with the arc opening of the arc rod facing the direction of the line clamp; the bottom end of the arc rod is horizontally hinged to the piston rod end of the drive cylinder.

[0014] Preferably, a right fixing bracket is arranged on the right side wall of the mounting slot plate. The right fixing bracket includes a right-end horizontal guide rod extending horizontally along the groove of the mounting slot plate. A slide rail on the right-end horizontal guide rod cooperates with a right-end slider. A right-end compression spring is sleeved on the right-end horizontal guide rod. The outer end of the right-end compression spring abuts against the right fixing bracket, and the inner end of the right-end compression spring abuts against the outer side wall of the right-end slider. A limiting block is installed on the inner side wall of the right-end slider. The limiting block passes through the right fixing bracket and extends into the groove cavity of the mounting slot plate. The bottom surface of the limiting block forms a mating surface that presses against the upper edge of the lower clamp plate from bottom to top. The upper edge of the end of the limiting block used to fit the side wall of the wire clamp is provided with an upper chamfer.

[0015] Preferably, the outer end of the left horizontal guide rod is fixed to the left positioning plate, and both the left positioning plate and the right slider are pulled outward by a pull tab.

[0016] Preferably, an installation method using the aforementioned irregularly shaped parallel groove wire clamp for fire mounting is characterized by comprising the following steps:

[0017] S1. Cable clamp installation steps:

[0018] Before installing the wire clamp, pull the tabs on both sides simultaneously to retract the top block and the limit block to avoid the wire clamp installation path; then, insert the wire clamp into the groove of the mounting plate, at which point the nut end of the fastening bolt extends into the installation opening; then, release the tabs on both sides, and the top block and the limit block will automatically reset due to the lateral elastic force.

[0019] At this time, the top block limits the lower edge of the upper clamping plate of the wire clamp, and the limiting block limits the upper edge of the lower clamping plate of the wire clamp.

[0020] S2, Sub-line Installation Steps:

[0021] Open the positioning part until the sub-line pressure bar is fully open; insert the sub-line into the wire clamp along the sub-line clamping opening formed after the sub-line pressure bar is opened, and then control the sub-line pressure bar to produce a hinge action until the sub-line is pressed tightly onto the guide groove at the lower clamping plate;

[0022] S3. Mainline Installation Steps:

[0023] Tighten the clamps at the section of the main line where the outer insulation has been removed, near the clamping opening. When the nut at the bolt end is tightened, the lower clamp remains stationary while the upper clamp moves downward, pressing the top block down to its lowest point and keeping it extended. Simultaneously, the limit block, due to its chamfered top, is pressed by the continuously descending upper clamp and retracts into the right side wall of the mounting slot, completing the tightening operation.

[0024] S4. Steps for removing the wire clamp:

[0025] After the tightening operation is completed, the auxiliary line pressure rod is reset under the action of the drive cylinder; the irregular grooved wire clamp is pulled down to connect to the fire installation fixture, and the top block interferes with the wire clamp's disengagement path. The lower clamping plate squeezes the lower chamfer of the top block until the top block retracts into the left groove wall of the mounting groove plate. At this time, the mounting groove plate is completely unlocked relative to the wire clamp, and the wire clamp is disengaged from the mounting groove plate and left on the main line.

[0026] Preferably, an installation device for using the aforementioned irregular grooved wire clamp fire mounting fixture is characterized in that: it further includes a striking assembly for tightening the nut at the nut end of the fastening bolt, the striking assembly being assembled on the bottom surface of the groove of the mounting slot plate, and the striking head of the striking assembly passing through the mounting opening and being coaxially arranged with the corresponding nut to be tightened.

[0027] Preferably, the striking assembly includes an outer bracket fixed to the bottom surface of the mounting slot plate; the striking heads are in two sets and arranged parallel to each other on their axes; the top of each striking head is recessed with an internal hexagonal countersunk hole matching the shape of the nut; the two sets of striking heads are rotatably fitted on the outer bracket; the bottom of each set of striking heads is coaxially mounted with a driven gear, and there is a height difference between the installation positions of the two sets of driven gears; the striking assembly also includes a striking motor with its axis vertically arranged; the output shaft of the striking motor is coaxially mounted with a driving gear; the driving gear meshes with the two sets of driven gears respectively, and the transmission ratios of the two sets of meshing driving gears and driven gears are the same.

[0028] The beneficial effects of this invention are as follows:

[0029] 1) Through the above solution, this invention provides a non-standard parallel groove wire clamp installation fixture, thereby providing a basic working platform for wire clamp installation under high-altitude mechanical operations. In actual operation, this invention controls the positioning direction of the wire clamp by installing a groove plate, and relies on the top block, as one of the core components, to provide support force on the upper clamp plate, thereby ensuring that the upper clamp plate remains detached from the lower clamp plate after the wire clamp is installed, thus preparing for the subsequent insertion and snapping of the main line and the auxiliary line. After the auxiliary line is inserted, the lower clamp plate is maintained in a downward state and position by the downward pressure of the positioning part on the auxiliary line. At this time, it can be seen that the upper clamp plate is limited by the top block, the lower clamp plate is limited by the positioning part, and the overall wire clamp is in an open state, thus providing the prerequisite for the subsequent clamping of the main line and the wire clamp fastening through the installation port. When the clamp is tightened, the upper clamp plate moves downward, and the vertical lifting part can be used to ensure the synchronous downward movement of the top block; when the clamp needs to be released, the retraction of the horizontal moving part ensures the retraction of the top block, thus clearing the release path for the clamp.

[0030] Thus, it can be seen that the present invention can ensure the smooth operation of locking, positioning, and even unloading of irregularly shaped parallel groove clamps, thereby effectively improving the working efficiency of parallel groove clamps, and the overall structure is also extremely compact and stable.

[0031] 2) For the vertical lifting section and the horizontal traversing section, they can be electrically controlled, such as through linear drive sources like electric cylinders, pneumatic cylinders, or lead screw and slider mechanisms. Considering the simplification and weight reduction of the overall structure, it is necessary to minimize the number of active mechanisms and reduce the number of force application points as much as possible; this is a key direction pursued by this invention. Therefore, this invention specifically realizes the actual structure of the vertical lifting section and the horizontal traversing section through the cooperation of corresponding guide rails, sliders, and even compression springs. In actual operation, due to the elastic restoring force of the compression spring, the top block can automatically move upward and automatically pop out, and the top block can naturally descend under the pressure of the upper clamp and naturally retract under the action of the wire clamp disengagement; the entire operation process is completely without active power, the process is simple and clear, and the operation is reliable and flexible.

[0032] 3) For each compression spring, it can also be replaced by other elastic reset structures such as elastic rubber strips or tension springs, which will not be elaborated here.

[0033] 4) In practice, the top block's function is to stably position the upper clamping plate before and during clamping; and to avoid the clamp's exit path when it comes out. Therefore, the top block does not necessarily need to be completely retracted into the side wall of the mounting slot. However, as a preferred solution, it is still advisable to consider a receiving opening design to ensure that the top block can be completely retracted into the side wall. This design allows the width of the mounting slot to perfectly match the width of the clamp, thus limiting the clamp's insertion and exit path.

[0034] 4) The receiving opening is shaped like an inverted "L," thus using the limiting effect of its shoulder to restrict the maximum downward distance of the top block. Of course, due to the special structure of the receiving opening, its side can penetrate the side wall of the mounting slot plate laterally, which is beneficial for actual processing and manufacturing.

[0035] 5) The top block, as one of the core components of this invention, also has a sophisticated structural design. The top surface of the top block is an upward-sloping wedge-shaped structure, and the highest point of the top surface forms a mating end that mates with the front end surface of the top block. Simultaneously, it is important to note that the contour of the bent surface formed by the top surface and the front end surface matches the contour of the inward curve on the side of the lower plate of the upper clamping plate near the main line clamping opening. This design allows the top block to support the upper clamping plate while utilizing the loose fit between the pre-tightened bolts and the holes in the upper clamping plate, ensuring that the upper clamping plate is in a special clamping state where "the end near the main line is tilted upwards." This clamping state, on the one hand, causes the other end of the upper clamping plate to sink down and get as close as possible to the secondary line pressed by the positioning part, ensuring that the secondary line can be quickly clamped when the upper clamping plate moves downwards, and relying on the secondary line to "reverse position" the relative positions of the upper and lower clamping plates, ensuring clamping reliability and accuracy. On the other hand, the upper clamp plate is tilted upwards at the end closest to the main line, which artificially enlarges the main line clamping opening of the clamp. This is obviously very beneficial for the quick insertion of the main line in the later stages of the invention, and has a significant positive impact on improving the accuracy and efficiency of the main line insertion.

[0036] 6) The positioning part is formed by extending from the guide fork of the sub-line. On the one hand, the positioning part can stably position the sub-line and even the lower clamping plate. On the other hand, the intermediate connection structure of the arc rod and the drive linkage can make the entire positioning part as close as possible to the main body of the equipment, and the overall volume and structure have been further optimized.

[0037] 7) During the assembly and fastening process of the wire clamp, the top block and the positioning part can respectively ensure the relative position of the upper and lower clamping plates. Building upon this, the invention further adds a limiting block and is equipped with a series of accessories. The purpose is to achieve a reliable downward limiting function of the lower clamping plate before the sub-wire is pressed down by the positioning part, or even before the sub-wire is inserted into the clamp, thereby improving operational convenience. Simultaneously, the dual limiting mode of the limiting block and the positioning part ensures that even under the impact force of the striking component, the lower clamping plate remains in a constant position, thus providing a precise downward reference for the upper clamping plate, ultimately ensuring the smoothness and stability of the wire clamp installation.

[0038] 8) For the left-end horizontal guide rod, the outer end is fixed with a left-end positioning plate. The left-end positioning plate and the right-end slider can be pulled outwards using a conventional power source. However, considering the presence of elastic components such as compression springs and the overall design aiming to minimize active power sources, this invention uses a manually controlled pull tab to ensure the outward pulling action of the left-end positioning plate and the right-end slider at the outer end of the left-end horizontal guide rod. This is because the wire clamp installation on-site is inevitably on the ground, allowing for manual assembly. Of course, whether subsequent operations are manual or mechanized can be determined based on the on-site conditions.

[0039] 9) Based on the above solution, the present invention also provides a corresponding installation method to specify its operation process, and through the optimal installation means, to further ensure the smoothness and convenience of the installation, positioning and release process of the wire clamp.

[0040] 10) Furthermore, the present invention also provides a matching striking assembly. Of course, striking assemblies are common equipment in the industry, used to achieve quick installation of nuts or bolts at wire clamps, either manually or mechanically. The present invention, through the presence of the mounting port, achieves rapid matching between the striking head and the nut at the wire clamp, facilitating subsequent convenient and automated operations.

[0041] 11) Since the assembly object of this invention is a double-bolt wire clamp, two sets of striking heads can be used to achieve synchronous striking operation. Simultaneously, considering the consistency of power, this invention employs a single striking motor, coupled with two sets of driven gears with the same transmission ratio, thereby achieving an efficient power transmission process. The two sets of driven gears have a height difference in their installation positions, which not only does not hinder normal meshing with the driving gear, but also further improves the overall compactness and miniaturization of the structure.

[0073] For ease of understanding, this section combines... Figure 1-20 The specific structure and operation of the present invention are further described below:

[0074] Figure 1-20 In the illustrated embodiment, the target is a non-standard grooved wire clamp a with a double-bolt structure. Of course, the present invention can also be adapted to accommodate non-standard grooved wire clamps a with three bolts or even other numbers of bolts.

[0075] For the sake of simplicity, “irregular grooved wire clamp a” will be referred to as “wire clamp a” below.

[0076] Based on the above description, the specific implementation structure of the present invention is as follows: Figure 1-20 As shown, it includes two main parts: a non-standard parallel groove wire clamping and installation fixture, and an impact assembly 100. Among them:

[0077] I. Irregularly shaped parallel groove wire clamping and installation fixture

[0078] Reference for the shape of the non-standard parallel groove wire clamp fire installation fixture Figure 16-19 As shown, the structure includes a mounting slot plate 10 as the main body of the structure. A left positioning component X is provided on the left side of the mounting slot plate 10, and a right positioning component Y is provided on the right side of the mounting slot plate 10. A positioning part 50 is also provided to ensure the effective clamping of the sub-line.

[0079] A. Left positioning component X

[0080] Left positioning component X, such as Figure 16-17 and Figure 19 As shown, Figure 1 and Figure 3 The actual assembly position can also be seen from the image. The left positioning component X surrounds the top block 20 as the core, thus forming a stable elastic system. In this elastic system, without the participation of an active force, the upper clamping plate a1 of the wire clamp a can move downward synchronously with the tightening action, without affecting the disengagement action of the lower clamping plate a2.

[0081] More specifically, during installation, the top block 20 relies on the vertical lifting part 30 and the horizontal moving part 40 to produce a predetermined action, and the vertical lifting part 30 and the horizontal moving part 40 are all fixed to the left side wall of the mounting slot plate 10 by using the left fixed frame 60 as the mounting base.

[0082] In actual assembly, the vertical lifting unit 30 includes a vertical guide rail 31 fixed on the vertical frame 33 and a vertical slider 32 that slides along the vertical guide rail 31. The vertical slider 32, through the vertical elastic part 34 (i.e., a compression spring), always generates a vertical upward reset action. The vertical slider 32 and the top block 20 are fixed to each other by a horizontal connecting rod 35 passing through a through hole. Meanwhile, the horizontal traversing unit 40 includes a left-end horizontal guide rod 41, which forms a horizontal guide rail sliding fit with the left fixed frame 60. The inner end of the left-end horizontal guide rod 41 is fixed to the vertical frame 33, thereby driving the vertical lifting unit 30 to generate a horizontal traversing action. The outer end of the left-end horizontal guide rod 41 is fixed to a left-end positioning plate 43, and a pull tab 90 is provided at the left-end positioning plate 43. During operation, the outward pulling action of the pull tab 90 can trigger the left-end horizontal guide rod 41 to pull outward relative to the guide hole at the left fixed bracket 60, thereby driving the entire vertical lifting part 30 to slide outward, thus achieving the retraction action of the top block 20 relative to the left side wall of the mounting slot plate 10. Furthermore, referring to... Figure 19 As shown, a left-end horizontal elastic part 42 is provided at the left-end horizontal guide rod 41. This left-end horizontal elastic part 42, i.e., a compression spring, constantly drives the vertical lifting part 30 and the top block 20 to produce a horizontally inward elastic reset action. Considering that the purpose of the top block 20 is to support the upper clamp a1, but the clamp a needs to avoid the top block 20 when it disengages, a lower chamfer 21 is provided at the lower edge of the end of the top block 20 that is used to fit the side wall of the clamp a. Therefore, when the clamp a moves upward, the lower chamfer 21 naturally compresses the left-end horizontal elastic part 42, ultimately driving the top block 20 to retract.

[0083] In the preferred configuration, the upper part of the top block 20 should present the following appearance: Figure 8The wedge-shaped structure shown matches a specific arc on the lower surface of the upper clamping plate a1, that is, the top surface is inclined and the highest point forms a bent surface with the front end surface sufficient to match the aforementioned specific arc. This bent surface allows the top block 20 to support the upper clamping plate, and the loose fit between the fastening bolt a3 and the hole in the upper clamping plate a1 ensures that the upper clamping plate a1 is in a special clamping state where "the end closer to the main line is upturned." (See actual reference...) Figure 8 As shown. This clamping configuration allows the other end of the upper clamping plate a1 to sink down and get as close as possible to the secondary line pressed by the positioning part 50. This ensures that the secondary line can be quickly clamped when the upper clamping plate a1 moves down, and the secondary line is used to "reposition" the relative positions of the upper clamping plate a1 and the lower clamping plate a2, ensuring clamping reliability and accuracy. On the other hand, the end of the upper clamping plate a1 closest to the main line is tilted upward, which artificially enlarges the main line clamping opening of the clamp a. This is obviously very beneficial for the rapid insertion of the main line in the later stages of the invention, and has a significant positive impact on improving the accuracy and efficiency of main line insertion. Of course, with the main line guide fork 71, its accuracy and efficiency will be even higher.

[0084] Furthermore, the top block 20 has an overall L-shaped block shape, and the inner end of the through hole is recessed with a receiving opening 61 for accommodating the top block 20. This allows the specific shape of the top block 20 to match the shoulder 62 of the receiving opening 61 on the left side wall of the mounting slot plate 10, thereby limiting the travel of the top block 20. Of course, the receiving opening 61 can also perfectly accommodate the top block 20, preventing interference between the top block 20 and the release path of the wire clamp a.

[0085] B. Right positioning component Y

[0086] The right positioning component Y is installed entirely on the right side wall of the mounting slot plate 10, such as... Figure 18-19 As shown, of course Figure 1 and Figure 3 The actual assembly position can also be seen from the image. The right positioning component Y uses the right fixed frame 80 as a carrier, on which the right horizontal guide rod 81 is fixed in a simply supported beam manner. The right horizontal guide rod 81 and the square plate-shaped right slider 82 form a guide rail sliding fit. The right slider 82 achieves outward pulling action by means of the pull tab 90; on the other hand, a limiting block 84 is installed on the inner side wall of the right slider 82. The limiting block 84 passes through the right fixed frame 80 and extends into the groove cavity of the mounting slot plate 10. The bottom surface of the limiting block 84 is pressed against the mating surface of the upper edge of the lower clamping plate a2 from bottom to top by the right end compression spring 83. Unlike the top block 20, which has a lower chamfer 21 to avoid the lower clamping plate a2, the purpose of the limiting block 84 is to limit the lower clamping plate a2. Therefore, it needs to avoid the downward path of the upper clamping plate a1. Therefore, the upper edge of the end of the limiting block 84 that is used to fit the side wall of the wire clamp a is provided with an upper chamfer 84a, as shown in the figure. Figure 19 As shown.

[0087] C. Positioning unit 50

[0088] To ensure the stability of the secondary line installation and further guarantee the positional consistency of the lower clamp a2 when the line clamp a is tightened, the design of the positioning part 50 is also quite important. The positioning part 50 is integrally attached to the mounting slot plate 10 to ensure a compact overall size.

[0089] For the specific structure of the positioning part 50, refer to Figure 2 and Figure 12 As shown, it includes a secondary line pressure rod 51 that is horizontally hinged to the top of the secondary line guide fork 72. The secondary line pressure rod 51 is sequentially connected to the drive cylinder 53 through the drive link 52 and the arc rod 54, thereby realizing the controllable switching between the opening and pressing postures of the positioning part 50.

[0090] II. Strike Component 100

[0091] Reference shape of the strike component 100 Figure 20 As shown, its assembly state is referenced. Figure 1-3 As shown.

[0092] The striking assembly 100 includes a striking motor 104, a gear set formed by a driven gear 103a and a driving gear 103b, arranged sequentially from bottom to top on an outer support 102, and a striking head 101 located at the uppermost end. The output shaft of the striking motor 104 is a single shaft, and it relies on the driving gear 103b to mesh with two sets of driven gears 103a respectively, thereby achieving the purpose of online power transmission with the same transmission ratio. The specific meshing state is described in [reference needed]. Figure 2-3 As shown in 9-11.

[0093] Since the assembly object of this invention is a double-bolt wire clamp a, two sets of striking heads 101 can be used to achieve the striking operation. In actual operation, the number of striking heads 101 can also be adjusted according to the difference in the number of bolts at wire clamp a. The top of the striking head 101 is recessed with an internal hexagon countersunk hole that matches the shape of the nut a4, such as... Figure 20 As shown.

[0094] Based on the above structure, this invention provides the following practical operation process, thereby further optimizing its operation procedures and ultimately improving its practical operation efficiency. Specifically:

[0095] S1, Cable clamp a installation steps:

[0096] Before installing clamp a, simultaneously as follows: Figure 4 Pulling the tabs 90 on both sides causes the top block 20 and the limiting block 84 to retract and avoid the installation path of the wire clamp a. Then, as shown... Figure 4 As shown, insert the wire clamp a into the groove of the mounting plate 10. At this time, the nut end of the fastening bolt a3 extends into the mounting opening 11. Then, as... Figure 6As shown, when the pull tabs 90 on both sides are released, the top block 20 and the limiting block 84 automatically reset due to the lateral elastic force.

[0097] At this time, the top block 20 limits the lower edge of the upper clamping plate a1 of the wire clamp a, and the limiting block 84 limits the upper edge of the lower clamping plate a2 of the wire clamp a.

[0098] S2, Sub-line Installation Steps:

[0099] Open the positioning part 50 until the secondary line pressure bar 51 is fully opened; after the secondary line pressure bar 51 is opened, the notch 12 at the exposed mounting slot plate 10 is referenced. Figure 19 As shown. Then, as... Figure 7 and Figure 8 As shown, the secondary wire is inserted into clamp a through the secondary wire clamping port along notch 12. The secondary wire pressing rod 51 is controlled to hinge until the secondary wire is pressed firmly against the guide groove at the lower clamping plate a2, as shown. Figure 9 As shown.

[0100] S3. Mainline Installation Steps:

[0101] Position the main line clamping port close to the section of the main line where the outer layer of insulation has been stripped. The main line then enters the clamping port at the notch 12 in the mounting slot 10. Next, tighten the clamp a. Refer to the main line clamping status. Figure 10 As shown. At this time, the striking motor 104 at the striking assembly 100 is turned on. The striking motor 104 drives the two sets of striking heads 101 to rotate in the same direction and at the same speed through the gear set, thereby driving the nuts a4 at the two fastening bolts a3 to rotate in the same direction and at the same speed. This ensures that the double bolt structure on the wire clamp a can be tightened simultaneously. The state of the wire clamp a after tightening is shown in the figure. Figure 11-13 As shown.

[0102] More specifically, during the tightening process of the double-bolt wire clamp a, the lower clamp a2 remains stationary, while the upper clamp a1 moves downward and presses down the top block 20 to the lowest point, maintaining the extended state of the top block 20. At the same time, due to the presence of the upper chamfer 84a, the limiting block 84 is squeezed by the continuously descending upper clamp a1 and retracts into the right side groove wall of the mounting groove plate 10, thus completing the entire tightening operation.

[0103] S4, Steps for removing clamp a:

[0104] After the tightening operation is completed, the auxiliary line pressure rod 51 is reset under the action of the drive cylinder 53, as follows: Figure 14 As shown. Then, pull down the irregularly shaped parallel grooved wire clamp and install the fixture. The top block 20 interferes with the release path of the wire clamp a. The lower clamp plate a2 presses against the lower chamfer 21 of the top block 20 until the top block 20 retracts into the left side groove wall of the mounting plate 10. At this point, the mounting plate 10 is completely unlocked relative to the wire clamp a, presenting as shown. Figure 15As shown in the diagram. After clamp a comes out of mounting plate 10, it will remain on the main line.

[0105] Thus, it can be seen that the present invention can perform the installation of heterogeneous parallel groove clamp a, thereby connecting the stripped outer insulation section of the main power cable (i.e., the main line) and the secondary power cable (i.e., the secondary line); after the installation of clamp a is completed, it is automatically unlocked without manual operation, which greatly improves the reliability and stability of the installation of heterogeneous parallel groove clamp a, and effectively reduces the labor intensity of power workers.
