Description

Technical Field

[0002] When relocating distribution network lines, it is often necessary to pull the three-phase four-wire power conductors, which need to cross communication lines or other power lines. Since the distribution network power conductors themselves are heavy and the height of the lines they cross is high, when pulling the conductors on site, workers usually need to stand on top of engineering vehicles or ladders to increase their standing height, and then swing the power conductors to the opposite side of the communication lines or other power lines. In this way, the power conductors will press on the communication lines or other power lines, which can easily cause damage to the communication lines or other power lines. In addition, since the power conductors are heavy, repeated operations are required to cross the power conductors from the communication lines or other power lines, and the operation process is time-consuming and labor-intensive.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0042] The embodiment of the present application provides a three-phase four-wire conductor pull-over device and a control method thereof, which solves the technical problems that the existing power conductor crossing line operation is time-consuming and labor-intensive, and is prone to damage to other power cables.

[0043] Example 1:

[0044] Figure 1 This is a front view structural diagram of the three-phase four-wire conductor cable jumper according to an embodiment of the present application. Figure 2 This is a side structural diagram of a three-phase four-wire conductor cable jumper according to an embodiment of the present application. Figure 3 This is a structural diagram of a wire pulling crossover mechanism in a three-phase four-wire wire pulling crossover according to an embodiment of the present application in a locked state. Figure 4 This is a schematic diagram of the top view of the three-phase four-wire conductor cable jumper described in an embodiment of the present application.

[0045] like Figures 1 to 4 As shown, an embodiment of the present application provides a three-phase four-wire conductor wire crossing device, including a lifting support mechanism 10, a base 20 and a conductor wire crossing mechanism 30.

[0046] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the lifting support mechanism 10 is used to raise or lower the height of the base 20 and the wire pulling wire crossing mechanism 30, and to provide support for the base 20 and the wire pulling wire crossing mechanism 30.

[0047] It should be noted that the three-phase four-wire conductor pulling wire crossing device can realize the operation of high-height conductor crossing lines through the lifting support mechanism 10, and there is no need for the operator to stand above other tools to increase the standing height, so that the three-phase four-wire conductor pulling wire crossing device can adjust the height of the conductor pulling wire crossing mechanism 30 through the lifting support mechanism 10 according to the height of the conductor crossing line, which is highly practical.

[0048] In the embodiment of the present application, the base 20 plays a supporting role, and the base 20 is arranged above the lifting support mechanism 10.

[0049] It should be noted that the base 20 provides support for the wire pulling and crossing mechanism 30 .

[0050] Figure 5 This is a schematic structural diagram of the push rod in the three-phase four-wire conductor pull-over device described in an embodiment of the present application.

[0051] like Figures 3 to 5As shown, in an embodiment of the present application, the wire pulling crossing mechanism 30 is used to cross and transport at least 4 cables 101 to be crossed. The wire pulling crossing mechanism 30 is installed on the base 20. The wire pulling crossing mechanism 30 includes a first driving source 31, a rotating shaft 32, at least four swing arm fixing assemblies 33 and a second driving source 35 connected to all the swing arm fixing assemblies 33 through a connecting rod 34. The first driving source 31 is set on the base 20, and the rotating shaft 32 is connected to the first driving source 31 and is set on the base 20 through the first support rod 102. Among them, each swing arm fixing assembly 33 includes a swing arm base 331, a swing arm 332, an upper roller 333 and a lower roller 334. The swing arm base 331 is set on the base 20, one end of the swing arm 332 is set on the swing arm base 331 through a rotating support shaft 335, the upper roller 333 is set on the other end of the swing arm 332, and the lower roller 334 is sleeved on the rotating shaft 32. A sliding groove 336 for moving the connecting rod 34 is provided on the swing arm 332, and the connecting rod 34 is connected to the second driving source 35 through a push rod 36. The push rod 36 at the end connected to the connecting rod 34 is provided with a detection element for detecting the tightening of the wire and a control element 361 for controlling the swing amplitude of the swing arm 332.

[0052] It should be noted that the detection element can be a pressure sensor, and the detection element is arranged at the groove of the push rod 36. The groove of the push rod 36 is matched and connected with the connecting rod 34. When the pressure data detected by the detection element reaches a set value, it can be determined that the cable 101 to be crossed on the wire pulling crossing mechanism 30 is matched with the corresponding upper roller 333 and lower roller 334 to carry out wire compression, thereby controlling the second driving source 35 to reverse and reset. In the present embodiment, the first driving source 31 and the second driving source 35 can both be selected as motors. The second driving source 35 can also be an electric or various forms of cylinder or push-type power device. When the wire pulling crossing mechanism 30 needs to compress the wire, the second driving source 35 is started, and the second driving source 35 rotates to drive the push rod 36 threaded column to rotate and then drive the push rod 36 to move in the direction of the connecting rod 34. When the push rod 36 is connected to the connecting rod 34, it pushes the connecting rod 34 to move upward in the slide groove 336. The upper roller 333, the swing arm 332 and the rotating support shaft 335 cooperate with each other to rotate around the rotating support shaft 335 under the action of the connecting rod 34 moving upward in the slide groove 336, thereby achieving the function of tightening the wire.

[0053] like Figure 3 As shown, in the embodiment of the present application, the push rod 36 is set on the swing arm base 331 through the push rod support rod 362. The push rod 36 is composed of two threaded columns connected by threads, and a sliding hole for accommodating the movement of the push rod 36 is provided on the corresponding push rod support rod 362.

[0054] Due to the complex and changeable working environment of the three-phase four-wire power conductor pulling site, the swing arm may have a large range of motion and space due to the limited conditions at the work site. If the swing arm moves, it may collide with obstacles in the surrounding environment (such as other wires, power poles, etc.), causing damage to the three-phase four-wire conductor pulling jumper and / or obstacles in the surrounding environment, resulting in certain safety hazards. Figure 5 As shown, in the embodiment of the present application, the three-phase four-wire wire pulling jumper is provided with a control element 361 on the push rod head of the push rod 36. The control element 361 is used to limit the opening range (such as the swing amplitude) of the swing arm 332. The control element 361 can be a magnetic attraction area composed of an electromagnetic coil. When the upper roller 333 is out of the wire pressing state, it can be understood that the swing arm 332 needs to bounce back. The electromagnetic coil is energized to generate magnetic force, which can attract the connecting rod 34 and thus control the swing amplitude of the swing arm 332.

[0055] In the embodiment of the present application, the first driving source 31 is disposed on the base 20 via a motor base 311 . The first driving source 31 is disposed on top of the motor base 311 .

[0056] In the embodiment of the present application, the lower roller 334 is disposed on the rotating shaft 32. There is an opening inside the lower roller 334. The rotating shaft 32 passes through the openings on both sides of the lower roller 334. When the rotating shaft 32 rotates, it drives the lower roller 334 to rotate.

[0057] In the embodiment of the present application, the swing arm 332 is provided on the swing arm fixing frame 103 , and the swing arm fixing frame 103 is used to fix and assist the rotation of the rotation support shaft 335 . The swing arm fixing frame 103 is provided on the swing arm base 331 .

[0059] The present application provides a three-phase four-wire conductor pulling crossover device, including a lifting support mechanism, a base and a conductor pulling crossover mechanism; the conductor pulling crossover mechanism is used to cross and transport at least four cables to be crossed, and the conductor pulling crossover mechanism is installed on the base. The conductor pulling crossover mechanism includes a first driving source, a rotating shaft, at least four swing arm fixing assemblies and a second driving source connected to all the swing arm fixing assemblies through a connecting rod, the first driving source is arranged on the base, the rotating shaft is connected to the first driving source and is arranged on the base through a first support rod; each swing arm fixing assembly includes a swing arm base, a swing arm, an upper roller and a lower roller, the swing arm base is arranged on the base, one end of the swing arm is arranged on the swing arm base through a rotating support shaft, the upper roller is arranged on the other end of the swing arm, and the lower roller is sleeved on the rotating shaft, and a sliding groove for moving the connecting rod is provided on the swing arm, and the connecting rod is connected to the second driving source through a push rod, and the push rod at the end connected to the connecting rod is provided with a detection element for detecting wire compression and a control element for controlling the swing amplitude of the swing arm.

Moreover, the three-phase four-wire conductor pulling wire crossing device can flexibly increase its height through the lifting support mechanism, and is suitable for wire crossings at different heights, solving the technical problems that the existing power conductor crossing operation is time-consuming and labor-intensive, and is prone to damage to other power cables.

The ratchet buckle 372 is connected to the first magnetic element 373 through a first elastic element 374, and the first magnetic element 374 provides magnetic force to separate the ratchet buckle 372 from the axial ratchet 371 to release the limiting lock on the swing arm 332.

[0064] like Figure 3 and Figure 7 As shown, in one embodiment of the present application, each swing arm fixing assembly 33 further includes a first support element 337 and a second support element 338 disposed on the swing arm base 331. When the upper roller 333 is in the wire-compressing working state, the first support element 337 abuts against the inner wall of the swing arm 332 to provide support to the swing arm. When the upper roller 333 is not in the wire-compressing working state, the second support element 338 abuts against the outer wall of the swing arm 332 to provide support to the swing arm 332. The first support element 337 is located on one side of the inner wall of the swing arm 332 and is a spring plate mounted on the swing arm base 331 via a spring seat 105.

[0065] It should be noted that the second magnetic element 339 can be a relay. The spring seat 105 is located at the upper end of the swing arm base 331.

[0068] In one embodiment of the present application, a wire support frame 21 is provided on the base 20 for assisting the wire to cross and correspondingly matches each swing arm fixing assembly 33 .

[0069] It should be noted that the wire support frame 21 is provided on the base 20 , and is used to assist the wires in crossing over, thereby preventing the cables 101 to be crossed from being damaged by friction between the cables 101 to be crossed and the base 20 .

[0070] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the lifting support mechanism 10 includes a base support rod 11, two fixed support rods 12, a fixing clamp 13, a fixing knob 14, a connecting rod 15, a triangular support structure 16 and a fixed base 17. The base support rod 11 is arranged below the base 20, and each fixed support rod 12 is connected to the triangular support structure 16 and fixed on the fixed base 17. The two fixed support rods 12 are respectively provided with a fixing clamp 13 and a fixing knob 14. By rotating the fixing knob 14, the fixing clamp 13 can be tightened to fix the base support rod 11 or the connecting rod 15; and / or, the bottom of the base support rod 11 is provided with a threaded groove connected to the connecting rod 15, and the upper and lower ends of the corresponding connecting rod 15 are provided with threads matching the threaded groove.

[0071] It should be noted that the bottom plate support rod 11 is located below the base 20, and a threaded groove is provided at the bottom of the bottom plate support rod 11. The fixed support rod 12 is connected to the triangular support structure 16 and fixed to the fixed base 17. The two fixed support rods 12 are respectively provided with a fixing clamp 13 and a fixing knob 14. By rotating the fixing knob 14, the fixing clamp 13 can be tightened to fix the bottom plate support rod 11 or the connecting rod 15. The connecting rod 15 has threads at both the upper and lower ends to facilitate connection and increase the height of the wire pulling crossover mechanism 30. The connecting rod 15 is connected to the bottom plate support rod 11 through a threaded rotation connection; the triangular support structure 16 is provided at the bottom of the fixed support rod 12 to fix the fixed support rod 12 and increase the firmness of the lifting support mechanism 10; the fixed base 17 is provided at the bottom of the entire three-phase four-wire wire pulling crossover, supporting and fixing the entire three-phase four-wire wire pulling crossover.

[0072] In an embodiment of the present application, the three-phase four-wire conductor pulling crossover can fix the base plate support rod 11 and the connecting rod 15 in the fixing clamp 13 during the pulling and crossing operation of the cable 101 to be crossed. The bottom of the base plate support rod 11 can be connected to the connecting rod 15 to increase the height of the conductor pulling and crossing mechanism 30. When in use, the four cables 101 to be crossed are placed in the middle of the lower roller 334, and the control swing arm 332 is rotated manually or automatically so that the upper roller 333 presses the cable 101 to be crossed, and the cable 101 to be crossed is firmly clamped between the upper and lower rollers. The spring plate is deformed under force to generate thrust, and the cable 101 to be crossed is maintained in a compressed state under the action of the shaft ratchet 371. When the cable 101 to be crossed reaches the target height, the first driving source 31 is started to drive the lower roller 334 to rotate, and the upper and lower rollers push the four cables 101 to be crossed forward through friction to achieve wire traction crossing. When the wire traction crossing is completed, the first magnetic element 373 and the second magnetic element 339 are started at the same time. After the first magnetic element 373 is started, the magnetic force generated will suck the ratchet buckle 372 to the top along the ratchet slide rail 376, making the shaft ratchet 371 invalid. The spring plate thrust pushes the swing arm 332 open. After the swing arm 332 swings to the position of the second support element 338, the second magnetic element 339 generates a magnetic force to fix the swing arm 332 on the second magnetic element 339. The upper and lower rollers release the wire, and the three-phase four-wire wire pulling and crossing device is moved to complete the wire traction and wiring, effectively solving the problem of power wire pulling and crossing.

[0073] Example 2:

[0074] Figure 8 This is a flowchart of the steps of the control method of the three-phase four-wire conductor cable jumper described in an embodiment of the present application.

[0075] like Figure 8As shown, the embodiment of the present application provides a control method for a three-phase four-wire wire cable spanning device, which is applied to the above-mentioned three-phase four-wire wire cable spanning device. The control method for the three-phase four-wire wire cable spanning device includes the following steps:

[0076] S1 obtains the height of the wire to be pulled across the operation; according to the height by adjusting the length of the lifting support mechanism through the connecting rod;

[0077] S2. Place the wire to be pulled in the middle of the lower roller, control the second drive source to drive all the swing arms forward and detect the pressure data of all the upper rollers downward through the detection element;

[0078] S3. According to the pressure data reaching the set value, it is determined that all the swing arm fixing components are pressing the wires, and the wire pulling mechanism is raised by the lifting support mechanism across the wire pulling mechanism, and then the first drive source is controlled to drive the shaft to rotate and convey the wires to be pulled on all the swing arm fixing components;

[0079] S4. After the crossing operation of the wire to be pulled is completed, each swing arm is controlled to be set on the second support element through the ratchet assembly or all the swing arms are driven to move backward through the second driving source until all the swing arms are set on the second support element, and then the wire pulling crossing mechanism is lowered through the lifting support mechanism.

[0080] It should be noted that the content of the three-phase four-wire conductor cable jumper has been described in Example 1, and will not be repeated in this embodiment. In this embodiment, the control method of the three-phase four-wire conductor pull-over device obtains data (such as the height) of the conductor to be pulled for wire traction and stringing in step S1, determines the length of the lifting support mechanism based on the height (the length is determined based on one or more connecting rods 15 and the bottom support rod 11), then uses the conductor pull-over mechanism 30 to compress all the conductors to be pulled 101 and obtain pressure data, and determines whether all the swing arm fixing assemblies have compressed the conductors based on whether the pressure data reaches a set value (determines whether all the swing arm fixing assemblies have compressed the conductors based on whether the pressure data reaches a set value), and then uses the lifting support mechanism to drive the cable to be crossed 101 to the target height, controls the first drive source to drive the rotating shaft to rotate and transport the conductors to be pulled on all the swing arm fixing assemblies; finally, after the crossing operation of the conductor to be pulled is completed, controls each swing arm to be set on the second support element through the ratchet assembly or drives all the swing arms to move backward through the second drive source until all the swing arms are set on the second support element, and then uses the lifting support mechanism to lower the conductor pull-over mechanism. In this embodiment, the set value can be set as needed and is not specifically limited here.

[0081] In one embodiment of the present application, after the crossing operation on the wire to be pulled is completed, the control method of the three-phase four-wire wire pulling crossover device further includes:

[0082] Obtain the shortest distance data between all swing arms and surrounding obstacles, and determine whether there is interference between each swing arm and surrounding obstacles based on the distance data;

[0083] If each swing arm does not interfere with surrounding obstacles, each swing arm is controlled to be placed on the second support element by the ratchet assembly or all the swing arms are driven to move backward by the second driving source until all the swing arms are placed on the second support element, and then the wire pulling crossover mechanism is lowered by the lifting support mechanism;

[0084] If at least one swing arm interferes with surrounding obstacles, the swing amplitude data of each swing arm moving backward is set according to the distance data; by adjusting the speed of the second driving source to drive all the swing arms to move backward and the driving control elements to work, all the swing arms are moved to the target position corresponding to the swing amplitude data; and then the wire pulling crossing mechanism is lowered through the lifting support mechanism.

[0085] It should be noted that after the crossing operation of the wire to be pulled is completed, the wire pulling crossing mechanism is also at the target height, and the shortest distance data between all swing arms and surrounding obstacles is obtained (such as measuring the distance between the swing arm and the surrounding limited space or surrounding objects through existing distance measurement technology, and filtering out the distance data with the smallest distance from the measured distances). When the shortest distance data determines that there is a risk of collision between the swing arm and obstacles in the surrounding environment (such as interference between at least one swing arm and surrounding obstacles), the extension distance of the push rod is adjusted according to the measured distance data to ensure that the extension distance is sufficient for the cable to be crossed to smoothly detach from the roller of the wire pulling crossing mechanism, and at the same time, the swing arm will not touch objects and damage the obstacles.

[0086] In this embodiment of the present application, the speed at which the second drive source drives all swing arms backward, as well as the control method for the operation of the drive control element, can be controlled by a time control module. Given the speed of the second drive source and the thread parameters of the push rod, the displacement per second of the push rod driven by the second drive source can be calculated. After the second drive source completes its push rod operation, it resets to its lowest point. Normally, after completing the wire pulling operation, the swing arm opens and is fixed to the second support element, with the upper roller fixed at its highest point. When at least one swing arm interferes with surrounding obstacles, the swing arm's open position is controlled by the push rod head. A swing arm position control command is provided. The push rod position is set as 0% based on the amount of push rod required to just allow the cable 101 to be crossed to be removed, and the position where the push rod overlaps with the second support element's fixed swing arm position is set as 100%. The value is adjusted based on the analysis results. The swing arm can be moved to a position where the cable to be crossed can be removed. The time required to reach 100% is multiplied by the percentage to achieve the desired position. This allows the swing arm to disengage the cable to be crossed from the wire pulling mechanism while also preventing interference with surrounding obstacles.

[0087] In the embodiment of the present application, the push-pull fine-tuning button for the second drive source can be controlled by adjusting the speed at which the second drive source drives all the swing arms backward and the control method of the drive control element. Under the action of the push-pull fine-tuning button, the second drive source rotates at a lower speed. When the swing arm needs to be opened to a preset position, it is directly controlled to the preset position or the push rod is pushed to the swing arm pressing position. In the open mode, the magnetic swing arm follows the push rod and slowly moves to the target position.

[0088] It should be noted that the control method of this three-phase, four-wire wire jumper, which adjusts the speed at which the second drive source drives all swing arms backward and the operation of the control element, allows for fine-tuning of the three-phase, four-wire wire jumper within the limited space of the swing arms, which takes a long time. In the unrestricted space of the swing arms, directly controlling the swing arms to open with the second support element significantly saves time, and raising the roller table to its highest point facilitates the removal of the cables to be crossed.
