Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to an upper-type J-shaped wire clamp installer. Background Art

[0002] The J-type wire clamp is a non-load-bearing wire clamp used to connect the secondary line of the branch line of a 10kV power line to the main line of the main line. Figure 1As shown, it includes two J-shaped guide blocks that are engaged with each other and a tensioning bolt that guides the two guide blocks to produce similar movements. During installation, the branch line's secondary line is embedded in the wire groove of one guide block, and the main line of the main line is embedded in the wire groove of the other guide block; the two guide blocks are tightened by the cooperation of the tensioning bolt and the tensioning nut, so that the secondary line and the main line are tightly clamped on the guide blocks, thereby realizing the current connection and guidance functions through the guide blocks. At present, the installation of the J-type wire clamp has gradually been semi-automated, and its installation process includes: the operator stands under the main line, and manually fixes the J-type wire clamp and the secondary line on the wire clamp installer, and then hooks the J-type wire clamp on the main line through the wire clamp installer; then, the striking part automatically tightens the tensioning bolt or the tensioning nut at the J-type wire clamp, so that the two guide blocks of the J-type wire clamp produce mutually opposite movements, so as to realize the simultaneous tightening function of the J-type wire clamp relative to the branch line and the main line; finally, the wire clamp installer and the J-type wire clamp are separated, and the whole installation process is completed. However, during the above installation process, people found that: on the one hand, since the early design of the wire clamp installer was based on manual installation, in other words, everything was designed to facilitate the operator to lift the pole for installation; therefore, the current wire clamp installers are all installed in a hanging style, that is, the capture claw of the wire clamp installer opens downward, and the entire wire clamp installer is first hooked on the main line during operation to reduce the labor caused by lifting the pole for a long time. However, with the development of intelligent robots, when the aerial work robot uses the above installer, due to its extremely stable position, the top-down hook installation has instead complicated the operation process; the robot arm needs to first operate the installer to lift and cross the main line, then determine the relative position of the main line and the capture claw, and then make the installer go down and hook from top to bottom. The overall operation efficiency is difficult to reach the ideal level, which needs to be solved urgently. On the other hand, since the screw sleeve at the striking part of the traditional wire clamp installer is directly driven by the striking motor and produces a rotating motion, that is, it only has a rotating motion around its own axis. When the sleeve engages with the tensioning nut and the tensioning nut rotates, the two guide blocks move relative to each other during the clamping process, and the tensioning nut rotates upward along the tensioning bolt. During this process, the tensioning nut will gradually detach from the sleeve, resulting in incomplete contact between the sleeve and the tensioning nut. The above incomplete contact phenomenon will make the assembly process of the J-type wire clamp inefficient at best, requiring frequent starting and stopping of the striking motor to ensure that the tensioning nut produces a rotating motion; at worst, the sleeve cannot continue to drive the tensioning nut, resulting in low clamping force of the wire clamp or even failure of the groove connection. Once the above situation occurs, the operator has to manually perform troubleshooting at high altitude, which is extremely time-consuming and labor-intensive. This obviously brings great trouble to the actual groove connection operation of the wire clamp. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a top-type J-type wire clamp installer to provide a basic working platform for online wire clamp installation operations under aerial mechanical operations; the present invention can further improve the wire clamp and groove working efficiency of the wire clamp installer, and the overall structure is also extremely compact and stable.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A top-type J-type wire clamp installer, including a positioning and mounting portion for placing the wire clamp, a striking portion for tightening a tightening bolt or a tightening nut at the wire clamp is arranged at the positioning and mounting portion, and is characterized in that: the positioning and mounting portion includes a base and a clamping rod extending vertically upward from the base, the clamping rods are two parallel to each other so that the gap between the two constitutes a placement channel for the wire clamp to be inserted along the length direction of the clamping rod, and a positioning component for fixing an upper guide block at the wire clamp is arranged in the placement channel; a secondary line locking clamp for positioning the secondary line and a main line guide clamp for positioning the main line are arranged on both sides of the positioning and mounting portion, the clamping opening of the main line guide clamp and the head end slot at the lower guide block of the wire clamp located in the placement channel are both facing upward, so that the main line can be guided into the head end slot via the main line guide clamp.

[0006] Preferably, the positioning assembly includes a slide groove recessed on the inner side surface of the clamp rod, the long direction of the slide groove is parallel to the insertion direction of the wire clamp relative to the placement channel, the groove cavity of the slide groove constitutes a guide cavity for the positioning anchor column at the wire clamp to be inserted and form a sliding fit of the guide rail; the lower groove end of the slide groove is a closed end, thereby forming a stop fit with the corresponding positioning anchor column at the upper guide block to limit the downward movement of the upper guide block; a lock hook that can be opened and closed is arranged at the upper groove end of the slide groove to limit the upward movement of the upper guide block.

[0007] Preferably, the lock hook is in a "C" shape, the bottom end of the lock hook is horizontally hinged at the clamping rod, and the top end of the lock hook horizontally penetrates the clamping rod and extends into the slide groove cavity; an anchor point is arranged on the hook body of the lock hook located outside the clamping rod, and the anchor point position and the hinge position of the bottom end of the lock hook avoid each other; the lock hook uses a locking tension spring to ensure that the top end of the lock hook is always located in the slide groove cavity; the locking cylinder or the locking electric push rod is fixed to the outer wall of the positioning mounting part, and the piston rod end of the locking cylinder or the locking electric push rod extends vertically upward and cooperates with the anchor point from top to bottom, so that the return action of the locking cylinder or the locking electric push rod is used to move the anchor point to ensure that the top end of the lock hook escapes from the slide groove cavity.

[0008] Preferably, the secondary line locking clamp includes a secondary locking rod, which has a "T"-shaped appearance, one end of the horizontal section of the secondary locking rod is horizontally hinged on the clamp rod through a support ear, and the other end of the horizontal section is bent to form a locking end for a swinging hook lock of the secondary line body, and the vertical section of the secondary locking rod extends toward the clamp rod to form a switch end; an adjustment hole is horizontally penetrated through the clamp rod, the adjustment hole is a waist-shaped hole and its hole length direction is vertically arranged, and a sliding rod is horizontally extended into the adjustment hole at the piston rod end of the locking cylinder or the locking electric push rod, and a slide rail guide is formed between the sliding rod and the adjusting hole; a matching relationship is formed between the sliding rod and the switch end, so that when the locking cylinder or the locking electric push rod generates a process movement During operation, the locking hook is unlocked and the wire clamp can be stuck in the placement channel, and then the switch end at the secondary locking rod begins to be pushed upward by the sliding rod, and the secondary locking rod swings accordingly to lock the secondary line; when the locking cylinder or the locking electric push rod produces a return action, the piston rod end of the locking cylinder or the locking electric push rod drives the anchor point downward, the locking hook is forced to open, the upper guide block loses the upward constraint, and at the same time, the switch end at the secondary locking rod loses the upward thrust of the sliding rod or the sliding rod actively pulls down the switch end, the secondary locking rod is unlocked, and the wire clamp escapes from the positioning installation part; the secondary line locking clamp also includes a secondary line groove for the secondary line to be placed from top to bottom, and the locking end of the secondary locking rod is in a warped shape with the end bent upward, so that the secondary line can be locked in conjunction with the secondary line groove.

[0009] Preferably, the auxiliary locking rods are in two groups and are respectively hinged on the corresponding clamping rods, and the hinged ends of the two groups of auxiliary locking rods are connected to each other by a transverse rod; the inner side surfaces of the two groups of clamping rods are recessed with accommodating grooves for accommodating the locking ends of the auxiliary locking rods, and the locking ends of the auxiliary locking rods avoid the auxiliary lines installed from top to bottom through the accommodating grooves.

[0010] Preferably, the main line guide clamp includes a main guide fork, the bottom end of which is fixed on the clamp rod, thereby forming a clamp-like structure with the bayonet facing upwards between the clamp rod and the main guide fork; a matching groove is arranged on the guide surface of the main guide fork, thereby matching with the first end groove at the lower guide block.

[0011] Preferably, the main line guide clamp also includes a secondary guide fork, which is hinged at the top of the clamp rod through a horizontal hinge seat; when the secondary guide fork is in a working state, the secondary guide fork cooperates with the main guide fork to form a "V"-shaped guide opening with an opening facing upward; when the secondary guide fork is in an initial state, the secondary guide fork generates a hinged action around the horizontal hinge seat until it completely avoids the travel path of the main line that detaches from the bottom to the top.

[0012] Preferably, the striking part includes a screw sleeve coaxially arranged with the tightening bolt, and the screw sleeve is driven by a striking motor to generate a coaxial rotational motion relative to the tightening bolt or the tightening nut; the installer also includes a compensation component for driving the screw sleeve to generate an axially similar motion relative to the tightening bolt or the tightening nut while the screw sleeve generates a rotational motion; the compensation component includes a transmission shaft coaxially fixed to the output shaft of the striking motor, an outer guide sleeve is coaxially provided outside the transmission shaft, and a non-rotating fit is formed between the outer guide sleeve and the transmission shaft, and the screw sleeve is coaxially assembled on the top end of the outer guide sleeve; the compensation component also includes an elastic member for driving the outer guide sleeve to generate an axial upward motion relative to the transmission shaft.

[0013] Preferably, the elastic member is a lifting compression spring, the elastic member is sleeved on the transmission shaft, and the top end of the elastic member extends upward and presses against the bottom end surface of the outer guide sleeve, and the bottom end of the elastic member extends downward and presses against the driving end of the striking motor; the transmission shaft is a square shaft, and the sleeve cavity shape of the outer guide sleeve is adapted to the outer wall shape of the transmission shaft, so that the two form a spline-type anti-rotation fitting relationship.

[0014] Preferably, an annular protrusion is coaxially arranged at the top end of the outer guide sleeve, and a locking tongue for limiting the axial upward movement of the outer guide sleeve is arranged on one side of the outer guide sleeve, and the locking tongue is controlled by the power member to produce a radial reciprocating linear movement relative to the outer guide sleeve; when the outer guide sleeve is in a low initial position, the locking tongue extends and is located above the annular protrusion, thereby forming a one-way stop fit with the annular protrusion; when the outer guide sleeve is in a high working position, the locking tongue retracts under the control of the power member, and the outer guide sleeve produces an axial lifting movement under the action of the elastic member; the power member is an electromagnet, and the locking tongue and the power member are connected to each other by a reset compression spring, so that when the power member is started, the reset compression spring is compressed by force to drive the locking tongue to retract.

[0015] The beneficial effects of the present invention are:

[0016] 1) Abandoning the traditional hanging-type installation structure, the top-type installation structure is used in a pioneering way, making it more suitable for use in remote sensing and intelligent machinery industries. Specifically, on the one hand, the traditional positioning installation structure with a striking part is still used to achieve the initial clamping of the wire clamp; on the other hand, after the secondary line locking clamp locks the secondary line, the lower guide block has the head end notch facing upward, rather than the traditional tail end inclined surface facing upward, which allows the main line to be guided downward along the main line guide clamp with the clamp facing upward, and then directly stuck in the head end notch, thereby achieving the purpose of main line positioning. When the main line falls into the above-mentioned head end notch, the striking part operates normally, that is, the purpose of reliable tightening of the wire clamp is achieved.

[0017] In summary, the present invention can provide a basic working platform for online wire clamp installation operations under high-altitude mechanical operations; the present invention can further improve the wire clamp and groove work efficiency of the wire clamp installer, and the overall structure is also extremely compact and stable. When necessary, the present invention can be fully applied in high-altitude remote sensing operation environments, that is, it can serve online remote sensing robots, thereby maximizing the reduction of human errors. At the same time, the operator can stay away from the on-site environment and perform remote sensing operations through the display screen, ultimately further improving the safety and efficiency of actual operations.

[0018] 2) The operation process of the wire clamp and groove is: first position the wire clamp, then fix the secondary line, and finally fix the main line. Therefore, in actual operation, it is necessary to first use the slide groove to ensure the installation state of the wire clamp, so that the tensioning bolt in the wire clamp is in a plumb state with the axis, and the nut or tensioning nut at the tensioning bolt is reliably inserted into the screw sleeve at the striking part from top to bottom; at this time, the forward and backward movements and left and right movements of the wire clamp are constrained. Subsequently, through the sealing design at the lower groove end of the slide groove and the controllable opening and closing lock hook at the upper groove end of the slide groove, the upward and downward movements of the upper guide block at the wire clamp are constrained. When the upper guide block is constrained, the lower guide block can produce an upward movement under the action of the striking part, thereby achieving the tightening effect of the wire clamp, and the operation is extremely clear.

[0019] 3) In the present invention, the lock hook and the secondary line locking clamp are linked, that is, when the lock hook is opened, the wire clamp can be inserted into the slide slot at any time. When the wire clamp is inserted into the slide slot, the first end notch of the upper guide block is naturally exposed to the position of the secondary locking rod, and the secondary line can be installed. Subsequently, the locking cylinder or the locking electric push rod continues to perform the process action until the secondary locking rod is pushed to start swinging. At this time, the secondary locking rod can automatically press the secondary line into the first end notch of the upper guide block through the locking end; it can also lock the secondary line by cooperating with the secondary line slot.

[0020] 4) For the main line guide clamp, it includes a main guide fork and a secondary guide fork, both of which aim to facilitate the main line to slide into the main line guide clamp along the guide surface through the guidance of each fork, and finally fall into the first end notch of the lower guide block; the above structure solves the problems of inaccurate installation position and slow installation of the wire clamp in the traditional sense, and simplifies the action process, making it more suitable for use by robots. The secondary guide fork adopts a movable guide fork, which plays a guiding role and does not interfere with the sliding out of the main line, which is obviously more convenient in operation.

[0021] 5) Based on the traditional rotary tightening of the tensioning bolt or the tensioning nut, the present invention further provides an axial compensation component, thereby achieving the purpose of the compound action of the "rotation + axial movement" of the screw sleeve. Because every time the screw sleeve rotates the tensioning nut or even the screw sleeve at the tensioning bolt, the threaded action of the tensioning nut and the tensioning screw sleeve will drive the two to produce similar actions, and at this time the tensioning bolt or the tensioning nut located in the screw sleeve will also produce axial action. Through the above-mentioned compound action of the screw sleeve, the present invention, every time the tensioning bolt or the tensioning nut travels a certain distance, the screw sleeve will produce a compensatory action, that is, it will travel a certain distance synchronously, so as to always ensure that the tensioning bolt or the tensioning nut is reliably located in the screw sleeve and forms a stable fit with the thread teeth at the screw sleeve, and finally ensure the reliable assembly effect of the screw sleeve relative to the J-type wire clamp.

[0022] 6) The compensation component can be implemented in a variety of ways, such as using a piston cylinder installed under the striking part. When the striking part rotates and drives the screw sleeve to produce a rotary motion, the piston cylinder produces a lifting motion to push the screw sleeve to produce an axial upward motion; or the striking part can be driven by a gear rack or even a crank slider to produce the above-mentioned upward motion. As a further preferred embodiment of the above scheme, the compensation component of the present invention is integrated in the striking part, thereby ensuring the compactness of the overall structure as much as possible, and is particularly suitable for use in high-altitude working environments with extremely high requirements on volume and weight. Specifically, the compensation component is integrated with the striking part through a transmission shaft, and the use state of the compensation component is ensured by an external guide sleeve and a lifting compression spring, and finally the established screw sleeve action purpose is achieved simply and reliably.

[0023] 7) The arrangement of the annular protrusion, on the one hand, is to form a shaft shoulder to fix and locate the position of the screw sleeve; on the other hand, it is to form a lock mouth, so as to cooperate with the lock tongue to achieve the self-reset and self-locking effect of the screw sleeve position. When it is necessary to tighten the tension bolt or the tension nut, the lock tongue retracts under the drive of the electromagnet. At this time, there is no obstruction above the annular protrusion, and the outer guide sleeve produces an axial upward action under the action of the lifting pressure spring, that is, the "rotation + axial upward" compound action of the screw sleeve is realized. When the assembly is completed, the screw sleeve needs to be reset for the next assembly; at this time, it is only necessary to press down the screw sleeve, and the screw sleeve and the annular protrusion go down together and press the lock tongue, and the lock tongue presses the reset pressure spring and produces a retraction action; after the annular protrusion passes over the lock tongue, the lock tongue will re-extend under the action of the reset pressure spring, that is, the locking action of the outer guide sleeve and even the screw sleeve is realized. Obviously, the above-mentioned whole set of processes is simple and reliable, and the number of required parts is extremely low, which can meet the operation requirements of compact workpieces with few parts and small volume.

[0049] For ease of understanding, here we combine Figure 1-13 Taking the installation and construction of a traditional J-type wire clamp as an example, hereinafter collectively referred to as a wire clamp, the specific structure and working method of the present invention are further described as follows:

[0050] The present invention can be used in remote control equipment such as robots; during actual assembly, the present invention can be fixed on a mechanical arm. At this time, since the main line is fixed as a reference object, the present invention can be completely lifted by the mechanical arm to complete the top-up wire clamp and groove operation relative to the main line. The traditional wire clamp installation method is to hook from top to bottom relative to the main line. The present invention adopts the opposite method of top-up installation relative to the main line. There is no need to make a crossing action during operation, so the complexity of the mechanical arm movement can be significantly reduced, which is convenient for the mechanical arm to dock with the main line operation, and is also more conducive to the use of high-altitude remote sensing robots.

[0051] Before actual installation, Figure 1 The conventional wire clamp shown in the figure is modified, that is, a screw is driven into the side of the upper guide block a as shown in 2, so as to form a positioning anchor column g. Of course, in actual operation, the positioning anchor column g can also be formed by driving a rivet or welding a column. The position of the positioning anchor column g should correspond to the position of the slide groove 13a at the positioning installation part 10, so as to facilitate later installation.

[0052] When the present invention actually works, its specific structure is as follows Figure 3-13 As shown, its main structure includes a positioning installation part 10 for fixing the wire clamp, a secondary line locking clamp 40 for fixing the secondary line B, and a main line guide clamp 30 for loading the main line A. When the main line and the secondary line are installed in place relative to the wire clamp, the striking part with the compensation component 23 is used to realize the lifting and rotating function of the tightening nut d, and finally the wire clamp, the main line A, and the secondary line B are tightly fixed to each other. Among them:

[0053] 1. Positioning and mounting part 10

[0054] The positioning and mounting portion 10 has an appearance as follows Figure 3-7 and Figure 10-13 As shown, it comprises a base 11, two clamping rods 12 or clamping plates extending upward from the base 11, and a positioning assembly 13. The two clamping rods 12 are arranged parallel to each other, and a slide groove 13a is arranged on one or both inner sides of the adjacent surfaces, so as to provide Figure 2 The anchor column g is inserted into the wire clamp shown in the figure; the inserted state is as shown in the figure. Figure 6 As shown in the figure, since the present invention adopts the top-up assembly method, when the striking part 20 strikes upward from the bottom, it is preferred to ensure that the upper guide block a is in a fixed state, so that the striking part 20 with a self-compensation function can screw the tightening nut d and drive the tightening nut d and even the lower guide block b to produce an upward movement relative to the upper guide block a.

[0055] When the upper guide block a is required to be in a fixed posture, refer to Figure 5-6 and Figure 12-13 As shown in FIG. 1 , when the chute 13a is opened, the lower end of the chute 13a does not reach the bottom, that is, there is a closed end. At this time, the lower end of the chute naturally forms a stop step to limit the upper guide block a from moving downward. On the other hand, the upper end of the chute 13a needs to be inserted from top to bottom for the positioning anchor column g, and also needs to limit the upper guide block a from moving upward. Therefore, as shown in FIG. Figure 12-13 The locking mechanism is arranged as shown. The locking mechanism includes a "C"-shaped lock hook 13b, the bottom end of which is hinged on the clamp rod 12, and the top end of the lock hook 13b is bent and penetrates the clamp rod 12 and then extends into the groove cavity of the slide groove 13a. In the natural state, the lock hook 13b is controlled by the locking tension spring and is always elastically pressed into the groove cavity of the slide groove 13a, and has a natural one-way locking function of "the positioning anchor column can go down but not up". When the lock hook 13b needs to be actively opened to facilitate the wire clamp to escape from the positioning installation part 10, the locking electric push rod 13d can be started, and the piston rod end of the locking electric push rod 13d moves downward and pulls down the anchor point 13c at the lock hook 13b, so that the lock hook 13b can be actively started, so that the upper groove end of the slide groove 13a forms an open state that is convenient for the wire clamp to escape.

[0056] 2. Secondary line locking clip 40

[0057] Secondary line locking clip 40 Figure 4-5 and Figure 12-13As shown, its main structure is formed by a combination of a secondary line groove 43, a secondary locking rod 41 and a transverse rod 42. The secondary locking rod 41 is divided into two groups, and a group of transverse rods 42 are matched to form a three-dimensional frame structure, so as to better hook the secondary line B laterally. The design purpose of the secondary line groove 43 is to improve the threading efficiency, and at the same time, it can cooperate with the secondary locking rod 41 to better bite the secondary line, which is convenient for the rapid installation of the secondary line B. Since the secondary line B is usually installed on the ground, it is necessary to pay attention to how the secondary line B can be unimpededly separated from the present invention after it is lifted into the air and the groove is completed with the main line clamp; in view of this, the secondary locking rod 41 of the present invention adopts a "T"-shaped plate structure. When in use, one end of the horizontal section of the secondary locking rod 41 is hinged to the clamp rod 12 through the support ear 41a, and the other end constitutes a locking end 41b with a gradually upward end, which is used to cooperate with the secondary line groove 43 to realize the bite-type fixing operation of the secondary line B. The vertical section of the secondary lock rod 41 extends toward the clamp rod 12 and forms a switch end 41c. At the same time, after the piston rod end of the locking electric push rod 13d passes horizontally through the adjustment hole on the clamp rod 12, it forms abutment or hinged fit with the switch end 41c of the secondary lock rod 41. In this way, whenever the locking electric push rod 13d performs a process action, it will drive the switch end 41c upward, and at this time the secondary lock rod 41 will produce a swinging action, and the warping structure of the locking end 41b can be used to cooperate with the secondary line slot to locate the secondary line position; refer to Figure 5 shown.

[0058] 3. Main line guide clip 30

[0059] The main line guide clamp 30 is designed to effectively guide the main line A downward when the present invention is pushed upward from the bottom, and the "V"-shaped design of the main line guide clamp 30 with the opening facing upward can effectively guide the main line A downward until the main line A falls into the matching groove 31a of the main guide fork 31 at the main line guide clamp 30. When the wire clamp is fixed, the head end notch e of the lower guide block b at the wire clamp is just at the same height as the matching groove 31a or there is a slight height difference, so the main line can also reliably fall into the head end notch e at this time.

[0060] When specifically designed, the main line guide clamp 30 is as follows Figure 3-7 and Figure 10-13 The main guide fork 31 and the auxiliary guide fork 32 are shown, and the purpose is to facilitate the main line to slide into the main line guide clamp 30 along the guide surface through the guidance of each fork, and finally fall into the head end notch e at the lower guide block b; the above structure solves the problems of inaccurate installation position and slow installation of the wire clamp in the traditional sense, and simplifies the action process, which is more suitable for use by robots. The auxiliary guide fork 32 adopts a movable guide fork, which plays a guiding role, and does not interfere with the sliding out of the main line, which is obviously more convenient in operation.

[0061] 4. Strike Department 20

[0062] The striking part 20 is one of the key parts of the present invention.

[0063] In fact, the striking part 20 is an indispensable part of the wire clamp holder; however, the traditional striking part is to tighten the nut of the tension bolt c or the tension nut d by the self-rotation of the screw sleeve 21, thereby completing the tightening function. The striking part 20 of the present invention has the functions of "tightening + self-compensation", especially under the premise that the upper guide block a is fixed, it can perfectly match the upward movement of the lower guide block b under the large stroke, and finally realize the simultaneous clamping function of the main line and the auxiliary line through the two guide blocks.

[0064] The specific structure of the striking part 20 of the present invention is shown in FIG. Figure 4 and Figure 7-11 As shown, its main parts include a screw sleeve 21, a striking motor 22 for driving the screw sleeve 21 to rotate, and a compensation component 23 for providing a compensation function for the screw sleeve 21. Among them:

[0065] The driving end of the striking motor 22 is coaxially fixed with a transmission shaft 23a to achieve power transmission, and the transmission shaft 23a is sleeved with an outer guide sleeve 23b in a rotation-proof manner, and a screw sleeve 21 is fixed to the top of the outer guide sleeve 23b. When the striking motor 22 is working, the transmission shaft 23a rotates accordingly, and drives the outer guide sleeve 23b to rotate through the key connection with the outer guide sleeve 23b, and finally drives the screw sleeve 21 to produce a rotational motion.

[0066] At the same time, an annular protrusion 23d is also arranged at the outer guide sleeve 23b. Figure 8-9 As shown, the electromagnetic lock forms a stopper. The electromagnetic lock includes an electromagnet constituting a power member 23f, a lock tongue 23e located at the working end of the electromagnet, and a return spring 23g connecting the lock tongue 23e and the electromagnet. When working, under the action of the return spring, the lock tongue 23e always extends to the outer guide sleeve 23b. When the screw sleeve 21 is in the initial state, that is, the low position state, as shown in FIG. Figure 8 As shown, at this moment, the locking tongue 23e is just located above the annular protrusion 23d, thereby pressing the annular protrusion 23d, so that the outer guide sleeve 23b and even the screw sleeve 21 no longer ascend. When the screw sleeve 21 needs to be used, the electromagnet is energized at this moment, and the locking tongue 23e is sucked, and the locking tongue 23e overcomes the force of the return compression spring 23g and retracts, thereby unlocking the annular protrusion 23d; Subsequently, the outer guide sleeve 23b produces an upward action under the action of the jacking compression spring constituting the elastic member 23c, thereby driving the screw sleeve 21 to ascend, and realizing the action purpose of the self-compensation type. When the screw sleeve 21 ascends, the outer guide sleeve 23b ascends relative to the transmission shaft 23a, and at the same time, the transmission shaft 23a applies a rotational force to the screw sleeve 21 through the outer guide sleeve 23b, i.e., the composite self-compensation action function of the "rotation+axial upward movement" of the screw sleeve 21 is guaranteed.

[0067] In order to further understand the present invention, Figure 1-13 , the actual working process of the present invention is described as follows:

[0068] 1) Get the traditional Figure 1 After the J-type wire clamp shown in the figure, the wire clamp is drilled and screws are installed to form the following Figure 2 The new wire clamp with positioning anchor post g is shown.

[0069] 2) Press the screw sleeve 21 of the present invention to make the screw sleeve 21 move downward and reset; at the same time, the locking electric push rod 13d moves downward, and the lock hook 13b is forced to open. When the locking electric push rod 13d returns and pulls the anchor point 13c at the lock hook 13b, so that the lock hook 13b is completely in the open state, the wire clamp is installed. Afterwards, install the new wire clamp of step 1). At this time, due to the presence of the positioning anchor column g, the positioning anchor column g will move downward along the direction of the slide groove 13a, thereby having the advantages of rapid installation and accurate installation of the wire clamp. The wire clamp can quickly and accurately reach the working position along the slide groove 13a. When the positioning anchor column is as Figure 6 After being clamped into the working position as shown; among the two positioning anchor posts g, the lower positioning anchor post is blocked by the lower groove end of the slide groove 13a, and the upper positioning anchor post will be blocked by the hook head of the lock hook 13b with a locking tension spring in the subsequent step 4), thereby realizing the reliable fixation of the upper guide block a of the wire clamp; at this time, the first end notch e of the lower guide block b faces upward, instead of the downward installation method of the traditional pull-down clamp. And in the process of the wire clamp going down along the slide groove 13a, the lock hook 13b is in an open state, that is, at this time, the piston rod end of the locking electric push rod 13d continues to apply a downward pulling force to the anchor point 13c at the lock hook 13b.

[0070] 3) Since the locking electric push rod 13d is always in the return state, the secondary lock rod 41 is also always in the open state, that is, the locking end 41b is always located in the receiving groove 12a. After the wire clamp is installed, the secondary wire is inserted through the secondary wire groove 43. After that, the locking electric push rod 13d performs a forward action, thereby pushing the switch end 41c of the secondary lock rod 41 through the guiding action of the adjustment hole and the slide rod 13e, and the secondary lock rod 41 produces a swing action until the secondary lock rod 41 cooperates with the secondary wire groove to bite the secondary wire. At this time, the secondary wire is Figure 2 It is shown as being located between the upper guide block a and the lower guide block b, but has not yet been reliably installed; the cooperation of the secondary locking rod 41 and the secondary line groove 43 can effectively fix the secondary line, preventing the failure of the line clamp and groove caused by the secondary line falling off and moving.

[0071] 4) When the locking electric push rod 13d performs the process action, the piston rod end of the locking electric push rod 13d will gradually relax the pressure on the anchor point 13c at the lock hook 13b, and the lock hook 13b will be reset under the action of the locking tension spring, thereby clamping the wire clamp and completing the upward and downward limit action of the upper guide block a at the wire clamp.

[0072] 5) When the secondary line is fixed and the lock hook 13b is reset, the electromagnet constituting the power member 23f is energized to absorb the lock tongue 23e and release the outer guide sleeve 23b with the annular protrusion 23d. Fig. 9 shown.

[0073] 6) When the striking begins, the screw sleeve 21 rotates and turns the tightening nut d. In the process of tightening the tightening nut d of the wire clamp, the lower guide block b and the tightening nut d continuously move upward; due to the elastic force of the lifting spring under the outer guide sleeve 23b, the outer guide sleeve 23b also performs a compensatory upward movement until the striking is completed.

[0074] 7) After the wire clamp is assembled, the locking electric push rod 13d generates a return action, driving the secondary line locking clamp 40 to reset and release the secondary line. At the same time, the locking electric push rod 13d also drives the lock hook 13b to move, and the lock hook 13b is actively opened. Then, the present invention is pulled down, and the present invention is completely separated from the wire clamp, and the wire clamp is left on the main line located at a high altitude, and finally the entire wire clamp and groove process is completed.

[0075] Since the present invention is an inverted top-mounted installation structure of the wire clamp, the main line is assembled from the bottom up. In actual operation, the present invention is lifted by a mechanical arm to complete the operation, so the main line is fixed and the entire device moves with the secondary line. Before the main line is connected, the secondary guide fork 32 will be reset under the action of gravity. At this time, the present invention is lifted by the mechanical arm to connect the main line from bottom to top. After the grooving is completed, the present invention is withdrawn from top to bottom. At this time, the secondary guide fork 32 will rotate automatically to avoid interference with the main line to be separated.
