[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] Embodiment 1:

[0044] Figure 1 This is a front view structural diagram of a three-phase four-wire conductor pull-through device according to an embodiment of the present application. Figure 2 This is a side view of the structure of the three-phase four-wire conductor cable jumper according to the embodiment of the present application. Figure 3 This is a structural schematic diagram of a wire pulling and crossing mechanism in a three-phase four-wire wire pulling and crossing device 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 structure 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 crossover can realize high-height conductor crossing line operation 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 crossover can adjust the height of the conductor pulling crossover mechanism 30 through the lifting support mechanism 10 according to the height of the conductor crossing line, and the practicality is strong.

[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 diagram of the structure of a push rod in a three-phase four-wire conductor pull jumper described in an embodiment of the present application.

[0051] like Figures 3 to 5As shown, in an embodiment of the present application, a wire pulling crossing mechanism 30 is used to cross and transport at least 4 cables 101 to be crossed, and the wire pulling crossing mechanism 30 is installed on a 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 arranged on the base 20, and the rotating shaft 32 is connected to the first driving source 31 and is arranged on the base 20 through a 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 opened on the swing arm 332. 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, and 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 the set value, it can be determined that the cable 101 to be crossed on the wire pulling and crossing mechanism 30 is matched with the corresponding upper roller 333 and the lower roller 334 to press the wire, and then control the second driving source 35 to reverse and reset. In this embodiment, the first driving source 31 and the second driving source 35 can be selected as motors, and the second driving source 35 can also be an electric or various forms of cylinder or push-type power device. When the wire pulling and 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 threaded column of the push rod 36 to rotate and then drive the push rod 36 to move toward the connecting rod 34. When the push rod 36 is connected to the connecting rod 34, the connecting rod 34 is pushed to move upward in the slide groove 336, and 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 realizing the function of tightening the wire.

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 set 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, 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 conductor wire 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 formed by 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 the 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. The lower roller 334 has an opening inside. The rotating shaft 32 passes through the openings on both sides of the lower roller 334. When the rotating shaft 32 rotates, the lower roller 334 is driven to rotate.

[0057] In the embodiment of the present application, the swing arm 332 is disposed 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 disposed on the swing arm base 331 .

[0058] In the embodiment of the present application, the first support rod 102 is disposed on the base 20. The first support rod 102 has a hole therein connected to the rotating shaft 32 to fix and support the rotating shaft 32.

[0069] It should be noted that the wire support frame 21 is disposed on the base 20 , and the wire support frame 21 is used to assist the wire to cross, so as to prevent the cable 101 to be crossed from being damaged by friction between the base 20 and the cable 101 to be crossed.

[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, a threaded groove connected to the connecting rod 15 is provided at the bottom of the base support rod 11, and threads matching the threaded groove are provided at the upper and lower ends of the corresponding connecting rod 15.

[0071] It should be noted that the bottom plate support rod 11 is arranged below the base 20, and a thread groove is arranged 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 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 bottom plate support rod 11 or the connecting rod 15. The upper and lower ends of the connecting rod 15 are threaded, which is convenient for connection and increases the height of the wire pulling wire crossing mechanism 30. The connecting rod 15 is connected to the bottom plate support rod 11 by thread rotation; the triangular support structure 16 is arranged 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 arranged at the bottom of the entire three-phase four-wire wire pulling wire crossing device, and plays a supporting and fixing role for the entire three-phase four-wire wire pulling wire crossing device.

[0072] In an embodiment of the present application, when the three-phase four-wire conductor pulling crossover is performing a wire pulling and crossing operation on the cable 101 to be crossed, the base support rod 11 and the connecting rod 15 can be fixed in the fixing clamp 13, and the bottom of the base 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, 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, and the spring plate is deformed under force to generate thrust, and the cable 101 to be crossed is maintained in a pressed 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 the 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 supporting 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, which effectively solves the problem of power wire pulling and crossing.

[0073] Embodiment 2:

[0074] Figure 8 This is a flow chart of the steps of the control method of the three-phase four-wire conductor wire 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 spanner, which is applied to the above-mentioned three-phase four-wire wire cable spanner. The control method for the three-phase four-wire wire cable spanner includes the following steps:

[0076] S1. Get the height of the wire to be pulled across the operation; adjust the length of the lifting support mechanism by connecting the rod according to the height;

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

[0078] S3. According to the pressure data reaching the set value, it is determined that all swing arm fixing components are pressing the wires, and the wire pulling and crossing mechanism is raised by the lifting support mechanism, and then the first driving source is controlled to drive the rotating shaft to rotate and transport the wires to be pulled on all 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 supporting 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 supporting 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 the first embodiment, and the content of the three-phase four-wire conductor cable jumper will not be repeated in this embodiment. In this embodiment, the control method of the three-phase four-wire conductor pull-over device obtains the data (such as height) of the conductor to be pulled for the conductor traction and stringing in step S1, determines the length of the lifting support mechanism according to the height (the length is determined according to one or more connecting rods 15 and the bottom plate support rod 11), and then compresses all the conductors to be pulled 101 through the conductor pull-over mechanism 30 and obtains the pressure data, and judges whether all the swing arm fixing components compress the conductors according to whether the pressure data reaches the set value (judgment that all the swing arm fixing components compress the conductors according to whether the pressure data reaches the set value), and then controls the first driving source to drive the rotating shaft to rotate and transport the conductors to be pulled on all the swing arm fixing components after the cable 101 to be crossed reaches the target height through the lifting support mechanism; finally, after the crossing operation of the conductor to be pulled is completed, each swing arm is controlled by the ratchet assembly to be set on the second support element or all the swing arms are driven to move backward by the second driving source until all the swing arms are set on the second support element, and then the conductor pull-over mechanism is lowered by the lifting support mechanism. In this embodiment, the set value can be set according to the demand, 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 there is no interference between each swing arm and the surrounding obstacles, each swing arm is controlled to be set 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 set 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 rotation speed of the second driving source to drive all the swing arms to move backward and the driving control element 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 selecting the smallest distance data 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 the swing arm will not touch the object and damage the obstacle.

[0086] In the embodiment of the present application, the speed of the second driving source driving all the swing arms to move backward and the control mode of the driving control element can be controlled by the time control module. When the speed of the second driving source and the thread parameters of the push rod are known, the displacement distance per second driven by the second driving source to move the push rod can be obtained. When the second driving source completes the push rod work, it will be reset to the bottom. Under normal circumstances, the swing arm is opened and fixed on the second support element after the wire pulling work is completed, and the upper roller is fixed at the highest point. When at least one swing arm is restricted by the environment that interferes with the surrounding obstacles, the swing arm opening position is controlled by the push rod head. A swing arm position control instruction is provided, and the push rod amount is taken as the value of 0% according to the value that the cable 101 to be crossed can just be taken out, and the position of the push rod and the second support element The fixed swing arm position overlaps with the reference setting adjustment value of 100%. According to the analysis result, the value can be adjusted, and it can be moved to the place where the cable to be crossed can be detached first, and the time required to reach 100% is multiplied by the percentage to achieve the swing arm reaching the preset position, so that the cable to be crossed can be separated from the wire pulling crossing mechanism, and the swing arm can also be prevented from interfering with the surrounding obstacles.

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

[0088] It should be noted that the control method of the three-phase four-wire wire pull-wire spanner can fine-tune the three-phase four-wire wire pull-wire spanner in the limited environment of the swing arm by adjusting the speed of the second driving source to drive all the swing arms to move backward and the driving control element to work, which takes a long time. In the unlimited space of the swing arm, the second supporting element directly controls the swing arm to open, which can greatly save time, and the upper roller table is at the highest point, which is convenient for taking out the cables to be crossed.
