Description

Technical Field

[0001] This utility model relates to the field of wire binding auxiliary technology, and in particular to a wire binding auxiliary device for power applications. Background Technology

[0002] In the power and telecommunications industries, power guy wires serve as crucial support structures for poles and towers, requiring secure binding for stability. Guy wire binding is a critical operation connecting the guy wires to the poles and towers; its quality directly impacts the safety and stability of the entire power line system. Loose binding can easily lead to pole tilting, guy wire breakage, and power outages. Power guy wire binding auxiliary devices are specialized tools designed to assist workers in securing guy wires (such as steel strands or galvanized iron wire) to poles and towers, and to guy rods. Their core function is to replace traditional manual binding.

[0003] However, existing auxiliary devices for binding power lines are not convenient for quickly binding and fixing the binding lines, nor are they convenient for monitoring the binding torque, making it difficult to quickly determine whether the binding meets the standards, and thus they are not very convenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an auxiliary device for binding power cables, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides an auxiliary device for binding power cables, including a fixed handle frame for support and fixation and containing a built-in battery. A binding torsion seat for providing power is fixedly installed inside the fixed handle frame. A dynamic torque sensor for monitoring torque is fixedly installed inside the binding torsion seat. The dynamic torque sensor is signal-connected to a microprocessor with a built-in algorithm for automated control. The microprocessor is signal-connected to a binding reference seat for engaging and fixing one end of the binding cable. A binding fixing block for pressing and tightening the other end of the binding cable is fixedly installed inside the binding fixing block. A pressure detection platform for detecting the binding cable is provided on one side of the binding fixing block. An adjusting locking rod for locking the binding torsion seat is provided on one side of the binding torsion seat. A control screen for displaying torque and pressure is provided on one side of the adjusting locking rod.

[0006] Preferably, one end of the fixed handle frame is provided with a non-slip grip, and the interior of the fixed handle frame is provided with a display slot for a fixed control screen. The control screen is signal-connected to a microprocessor, and the microprocessor is located inside the fixed handle frame and connected to a battery.

[0007] The above technical solution employs the following: the anti-slip grip (TPR material) of the fixed handle frame provides a stable grip interface for operators, preventing slippage during operation; the display slot inside the frame precisely fixes the control screen, ensuring screen stability; the control screen has a bidirectional signal connection with the microprocessor, which can display data such as torque, pressure, and battery level in real time, while simultaneously receiving touch commands and transmitting them to the microprocessor for human-machine interaction; the microprocessor is built into the frame cavity and directly connected to the battery, providing stable power supply to itself and its components; the textured design of the anti-slip grip increases the coefficient of friction for the hand, reducing the slippage rate even in oily or sweaty environments; the elasticity of the TPR material dampens grip vibrations, reducing hand fatigue during prolonged operation; the high-precision dimensions of the display slot prevent screen loosening during high-altitude operations, adapting to outdoor power operation scenarios; and the signal connection between the microprocessor and the control screen has a fast response, allowing for quick execution of commands such as "start binding" and "switch mode".

[0008] Preferably, in any of the above embodiments, the binding torsion seat includes a drive motor connected to a microprocessor signal and a rotating seat for transmitting power. The drive motor is fixedly installed inside the fixed handle frame, and the output end of the drive motor is fixedly installed with a rotating seat that rotates inside the fixed handle frame. The dynamic torque sensor is fixedly installed inside the fixed handle frame and fixedly installed with the output shaft of the drive motor.

[0009] The above technical solution is adopted as follows: the drive motor (DC brushless motor) of the binding torsion seat is fixed inside the fixed handle frame, and the output shaft is rigidly connected to the rotating seat through a coupling. Stepless speed regulation can be achieved under the control of a microprocessor. The rotating seat has bolt holes on its surface for fixing the connecting seat of the binding reference seat. It can rotate circumferentially and drive the reference seat to rotate synchronously. A dynamic torque sensor (strain gauge type) is connected in series between the output shaft of the drive motor and the coupling to collect the output torque of the motor in real time. The analog signal is transmitted to the microprocessor through a signal line. The stainless steel material of the rotating seat is resistant to outdoor corrosion. The precise machining of the bolt holes ensures the installation accuracy of the connecting seat and avoids binding offset caused by the shaking of the reference seat. The coupling can compensate for the installation coaxiality deviation between the output shaft of the drive motor and the rotating seat and avoid the additional bending moment generated by rigid transmission from damaging the shaft system. The high-precision detection of the dynamic torque sensor can capture the torque change in real time during the binding process. When the torque exceeds the load, the microprocessor immediately controls the motor to reduce the speed to prevent the binding line from breaking.

[0010] Preferably, in any of the above embodiments, the binding reference base includes a supporting connecting base, an electric telescopic rod connected to a microprocessor signal, and a clamping plate for clamping and securing the binding wire. The connecting base is fixedly installed at one end of the rotating base, and the electric telescopic rod is fixedly installed inside the connecting base. One end of the electric telescopic rod is fixedly installed with a clamping plate that moves inside the connecting base.

[0011] The above technical solution is adopted as follows: the connecting seat of the binding reference base is fixed to the rotating seat by bolts, providing an installation reference for the electric telescopic rod and the biting plate. The electric telescopic rod (mini electric push rod) is fixed inside the connecting seat, and its output end is rigidly connected to the biting plate. It can extend and retract under the control of a microprocessor, driving the biting plate to move. The biting plate (made of wear-resistant alloy) is located in the biting groove of the connecting seat and can slide along the groove. It fixes one end of the binding line by clamping with the groove wall. The stainless steel material of the connecting seat is wear-resistant. The bolt fixing method ensures a firm connection with the rotating seat and avoids loosening during rotation. The adjustable stroke of the electric telescopic rod can be adjusted according to the diameter of the binding line to prevent the binding line from slipping during binding. The anti-slip teeth of the biting plate can be embedded in the surface of the binding line to increase the friction coefficient and further enhance the fixing reliability, adapting to the needs of long-term high-frequency operation.

[0012] Preferably, in any of the above embodiments, the binding and fixing block includes a pneumatic telescopic rod connected to a microprocessor signal and a clamping plate for pressing the binding wire. The pneumatic telescopic rod is fixedly installed inside the connecting seat, and a clamping plate located on one side of the connecting seat is fixedly installed at one end of the pneumatic telescopic rod. The clamping plate is configured as an L-shaped structure.

[0013] The above technical solution is adopted as follows: the pneumatic telescopic rod (miniature cylinder) of the binding and fixing block is fixed inside the connecting seat (perpendicularly distributed with the electric telescopic rod), and is connected to the microprocessor signal through the solenoid valve to realize rapid extension and retraction. The L-shaped clamping plate is fixed to the output end of the pneumatic telescopic rod and can move to the outside of the connecting seat. Through cooperation with the side wall of the connecting seat, it presses and fixes the other end of the binding wire that passes around the power cable. The high thrust of the pneumatic telescopic rod can meet the pressing requirements of the binding wire, ensuring that the binding wire does not loosen when rotating and winding. The fast response time can be synchronized with the biting action of the binding reference seat without affecting the overall binding efficiency. The L-shaped structure design allows the clamping plate to fit against the surface of the circular power cable, avoiding damage to the cable during pressing. The inner silicone pad can increase the friction coefficient with the binding wire and cable, preventing the binding wire from shifting after pressing, while buffering the pressing force to avoid damaging the coating of the binding wire. The detachable connection between the clamping plate and the pneumatic telescopic rod facilitates the subsequent replacement of worn silicone pads.

[0014] Preferably, in any of the above embodiments, the pressure testing station includes a pressure sensor connected to a microprocessor signal and a pressure-bearing extrusion plate. The pressure sensor is fixedly installed inside the connecting seat, and the extrusion plate located inside the connecting seat is fixedly installed at the detection end of the pressure sensor.

[0015] The above technical solution employs two piezoelectric pressure sensors on the pressure testing station, fixed inside the connector at the corresponding engagement groove and pressing area. These sensors are connected to a microprocessor via signal lines to collect the engagement and pressing pressures of the binding thread in real time. An extrusion plate, fixed to the detection end of the pressure sensor and exposed in the engagement groove and pressing area, directly contacts the binding thread, converting the local pressure of the binding thread into a uniform surface pressure that is transmitted to the sensor. The high precision and rapid response of the pressure sensor accurately capture subtle changes in engagement and pressing pressures, preventing the binding thread from loosening during rotation due to insufficient pressure or damaging it due to excessive pressure. The two sensors operate independently, monitoring the pressures of the engagement and pressing stages separately. This allows the microprocessor to adjust the movements of the electric and pneumatic telescopic rods accordingly. The smooth surface of the extrusion plate prevents scratches on the binding thread surface and increases the contact area with the binding thread, eliminating detection errors caused by localized protrusions in the binding thread and improving the accuracy of the pressure data.

[0016] Preferably, in any of the above embodiments, the adjusting locking rod includes a rotating disk providing support, a fastening spring providing supporting force, and a locking slide rod engaging the rotating seat. The rotating disk is rotatably connected to the interior of the fixed handle frame. One end of the rotating disk is fixedly installed with a fastening spring located inside the fixed handle frame. One end of the fastening spring is fixedly installed with a locking slide rod that moves inside the fixed handle frame. One end of the locking slide rod is provided with a positioning boss that is movably connected to the interior of the fixed handle frame.

[0017] The above technical solution is adopted as follows: the rotating disk (ABS plastic material) of the adjusting locking rod is rotatably connected to the side wall of the fixed handle frame, which is convenient for the operator to rotate manually. The fastening spring is fixed to one end of the rotating disk and located inside the frame, providing a return spring force for the locking slide rod. The locking slide rod is fixed to the other end of the fastening spring and can slide along the guide hole inside the frame. The locking head can be locked into the locking hole in the circumferential direction of the rotating seat to realize the locking and unlocking of the rotating seat. The ABS material is lightweight and does not increase the overall burden of the device. The high elasticity coefficient of the fastening spring ensures that the spring force is sufficient when compressed, pushing the locking slide rod to tightly lock into the locking hole, preventing the rotating seat from rotating accidentally in the automatic binding mode. The positioning boss design at one end of the locking slide rod is easy to operate and facilitates manual unlocking.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. A binding reference seat and a binding fixing block are set up to engage and fix the binding wire. By tightening the binding reference seat and the binding fixing block, the two ends of the binding wire can be joined and fixed. The binding torsion seat drives the binding reference seat and the binding fixing block to quickly bind the bound wire after they have joined. At the same time, a dynamic torque sensor is used to detect the binding torque, which facilitates accurate judgment of the binding degree, improves the binding accuracy, and enhances the binding convenience.

[0019] 2. An adjustable locking rod is installed inside the fixed handle frame to lock and control the binding torsion seat. By locking the binding torsion seat, the manual binding state can be switched. The auxiliary device can be switched between automatic binding and manual binding according to the binding needs, improving the convenience of using the auxiliary device.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figure 1-4As shown in the figure, an auxiliary device for binding power cables according to an embodiment of the present invention includes a fixed handle frame 1 for support and fixation and with a built-in battery. A binding torsion seat 2 for providing power is fixedly installed inside the fixed handle frame 1. A dynamic torque sensor 3 for monitoring torque is fixedly installed inside the binding torsion seat 2. The dynamic torque sensor 3 is signal-connected to a microprocessor with a built-in algorithm for automatic control. The microprocessor is signal-connected to a binding reference seat 4 for clamping and fixing one end of the binding cable. A binding fixing block 5 for pressing and tightening the other end of the binding cable is fixedly installed inside the binding fixing block 4. A pressure detection platform 6 for detecting the binding cable is provided on one side of the binding fixing block 5. An adjusting locking rod 7 for locking the binding torsion seat 2 is provided on one side of the binding torsion seat 2. A control screen 8 for displaying torque and pressure is provided on one side of the adjusting locking rod 7.

[0024] Preferably, one end of the fixed handle frame 1 is provided with a non-slip grip, and the interior of the fixed handle frame 1 is provided with a display slot for the fixed control screen 8. The control screen 8 is connected to the microprocessor, and the microprocessor is located inside the fixed handle frame 1 and connected to the battery.

[0025] The above technical solution is adopted as follows: the anti-slip grip (TPR material) of the fixed handle frame 1 provides a stable grip interface for the operator and avoids slipping during operation. The display slot inside the frame precisely fixes the control screen 8 to ensure the stability of the screen position. The control screen 8 is bidirectionally connected to the microprocessor and can display data such as torque, pressure, and battery level in real time. At the same time, it receives touch commands and transmits them to the microprocessor to realize human-machine interaction. The microprocessor is built into the cavity of the frame and is directly connected to the battery to provide stable power supply for itself and various components. The textured design of the anti-slip grip increases the coefficient of friction for the hand, which can reduce the slippage rate of the device even in oily or sweaty environments. At the same time, the elasticity of the TPR material can dampen grip vibration and reduce hand fatigue during long-term operation. The high-precision size of the display slot prevents the screen from loosening during high-altitude operations and is suitable for outdoor power operation scenarios. The signal connection between the microprocessor and the control screen has a fast response and can quickly execute commands such as "start binding" and "switch mode".

[0026] The anti-slip grip is based on the principle of friction, increasing the contact roughness between the hand and the grip to enhance static friction. The display slot is mechanically fixed to the control screen 8 via clips, restricting the screen's three-dimensional displacement. The control screen 8 is based on capacitive touch and LCD display principles. During touch operation, the capacitive sensing layer detects the finger position, converts the coordinate signal into an electrical signal, and transmits it to the microprocessor. The microprocessor processes the signal and outputs control commands. Simultaneously, it converts the torque and pressure data collected by the sensors into visual information displayed on the screen. The microprocessor, as the control core, uses a power management module to stably convert the 12V voltage of the battery into 3.3V and 5V to power components such as sensors and motors. Before operation, the operator checks whether the anti-slip grip is intact, embeds the control screen 8 into the display slot, and fixes it with clips. Once the device is secure and the connection is secure, power is switched on. The battery supplies power to the microprocessor and control panel 8. The screen lights up and enters a 3-second self-test interface. After the self-test passes, the microprocessor initializes all sensors and actuators, and the device enters standby mode. During operation, the operator presets the binding parameters via the touchscreen. After binding begins, the screen updates dynamic data in real time. If low battery or abnormal parameters occur, the screen will immediately flash an alarm. After the operation is completed, the power is switched off. If charging is required, the charger is plugged into the USB port at the bottom of the frame. The microprocessor has a built-in battery management algorithm that monitors the battery voltage in real time. When the voltage is ≤11.1V, low battery protection is triggered, preventing the drive motor 21 from starting and avoiding over-discharge of the battery. The touch commands on control panel 8 use a "two-click confirmation" mechanism to prevent accidental operation (such as accidentally touching the "start" button).

[0027] Preferably, the binding torsion seat 2 includes a drive motor 21 connected to a microprocessor signal and a rotating seat 22 for transmitting power. The drive motor 21 is fixedly installed inside the fixed handle frame 1. The output end of the drive motor 21 is fixedly installed with the rotating seat 22 that rotates inside the fixed handle frame 1. The dynamic torque sensor 3 is fixedly installed inside the fixed handle frame 1 and fixedly installed with the output shaft of the drive motor 21.

[0028] The above technical solution is adopted: the drive motor 21 (DC brushless motor) of the binding torsion seat 2 is fixed inside the fixed handle frame 1, and the output shaft is rigidly connected to the rotating seat 22 through a coupling. It can achieve stepless speed regulation under the control of microprocessor. The rotating seat 22 has bolt holes on its surface for fixing the connecting seat 41 of the binding reference seat 4. It can rotate circumferentially and drive the reference seat to rotate synchronously. The dynamic torque sensor 3 (strain gauge type) is connected in series between the output shaft of the drive motor 21 and the coupling to collect the motor output torque in real time. The analog signal is transmitted to the microprocessor through the signal line. The stainless steel material of the rotating seat 22 is resistant to outdoor corrosion. The precise machining of the bolt holes ensures the installation accuracy of the connecting seat 41 and avoids binding offset caused by the shaking of the reference seat. The coupling can compensate for the installation coaxiality deviation between the drive motor output shaft and the rotating seat 22 and avoid the additional bending moment generated by rigid transmission from damaging the shaft system. The high-precision detection of the dynamic torque sensor 3 can capture the torque change in real time during the binding process. When the torque exceeds the load, the microprocessor immediately controls the motor to reduce the speed to prevent the binding line from breaking.

[0029] The drive motor 21 is based on the principle of electromagnetic induction. The PWM signal output by the microprocessor adjusts the direction and magnitude of the current in the motor windings through the motor drive module to achieve precise control of speed and torque. The rotating seat 22 is based on the principle of rigid transmission, which transmits the rotational power of the motor to the connecting seat 41 through bolts, causing the binding reference seat 4 and the binding fixing block 5 to rotate synchronously, so that the binding wire forms a spiral winding structure around the power cable. The dynamic torque sensor 3 is based on the principle of strain effect. The torque output by the motor causes the elastic body inside the sensor to produce a small deformation. The resistance value of the strain gauge attached to the elastic body changes with the deformation. The resistance change is converted into a voltage signal through a Wheatstone bridge, and amplified into a standard signal by the signal conditioning circuit. The microprocessor converts the analog signal into a digital torque value through an AD converter. Before binding, the motor speed and number of winding turns are preset on the control screen 8 according to the binding wire specifications. After the operator fixes both ends of the binding wire to the binding reference seat 4 and the binding fixing block 5 respectively, they click the "start" button on the control screen. The microprocessor sends a signal to the drive motor 21. 1. A PWM signal is sent, the motor starts and drives the rotating seat 22 to rotate through the coupling. The rotating seat synchronously drives the connecting seat 41, the biting plate 43, and the pressing plate 52 to rotate. The binding wire begins to wind around the power cable. During the winding process, the dynamic torque sensor 3 transmits torque data to the microprocessor once every 1ms. The screen displays the torque value in real time. When the torque reaches the preset value of 4 N·m and the number of winding turns meets the standard, the microprocessor controls the motor to stop and rotate in the reverse direction to reset the rotating seat. If a cable burr is encountered during the winding process, causing a sudden increase in torque, the microprocessor immediately reduces the PWM duty cycle of the motor to make the torque fall back to a safe range. Using a PID closed-loop control algorithm, the microprocessor compares the feedback value of the dynamic torque sensor 3 with the preset torque value, calculates the deviation, and outputs an adjustment signal. By changing the PWM duty cycle of the drive motor 21, the actual torque is stabilized within the preset value range. The forward and reverse rotation control logic of the motor is set. Forward rotation is used for binding, and reverse rotation is used for unbinding (in case of binding failure, press and hold the "Unbind" button on the control screen to start).

[0030] Preferably, in any of the above embodiments, the binding reference base 4 includes a supporting connecting base 41, an electric telescopic rod 42 connected to a microprocessor signal, and a clamping plate 43 for clamping and securing the binding wire. The connecting base 41 is fixedly installed at one end of the rotating base 22, and the electric telescopic rod 42 is fixedly installed inside the connecting base 41. The clamping plate 43, which moves inside the connecting base 41, is fixedly installed at one end of the electric telescopic rod 42.

[0031] The above technical solution is adopted as follows: the connecting seat 41 of the binding reference seat 4 is fixed to the rotating seat 22 by bolts, providing an installation reference for the electric telescopic rod 42 and the biting plate 43. The electric telescopic rod 42 (mini electric push rod) is fixed inside the connecting seat 41, and its output end is rigidly connected to the biting plate 43. It can extend and retract under the control of a microprocessor, driving the biting plate to move. The biting plate 43 (wear-resistant alloy material) is located in the biting groove of the connecting seat 41 and can slide along the groove. It fixes one end of the binding line by clamping with the groove wall. The stainless steel material of the connecting seat 41 is wear-resistant. The bolt fixing method ensures a firm connection with the rotating seat 22 and avoids loosening during rotation. The adjustable stroke of the electric telescopic rod 42 can be adjusted according to the diameter of the binding line to prevent the binding line from slipping during binding. The anti-slip teeth of the biting plate 43 can be embedded in the surface of the binding line to increase the friction coefficient and further enhance the fixing reliability, which is suitable for long-term high-frequency operation.

[0032] The electric telescopic rod 42 is based on the screw drive principle. An internal motor drives the screw to rotate, and the engagement of the screw and nut converts the rotational motion into linear motion, pushing the engagement plate 43 to slide along the engagement groove of the connecting seat 41. The engagement plate 43 and the engagement groove wall form a clamping structure. Utilizing a dual fixing method of "surface contact + tooth engagement," the thrust of the electric telescopic rod generates clamping pressure. The anti-slip teeth physically engage to restrict the axial sliding of the binding thread, preventing it from loosening during rotational binding. The connecting seat 41 acts as a support carrier, transmitting the rotational power of the rotating seat 22 to the engagement plate 43 and the electric telescopic rod 42, ensuring synchronous rotation of all three and achieving binding thread winding. The operator places one end of the binding thread into the engagement groove of the connecting seat 41, ensuring the thread adheres to the groove wall. Clicking the "engagement and fixation" button on the control screen 8 sends an extension command to the electric telescopic rod 42. The telescopic rod pushes the clamping plate 43 towards the groove wall, gradually clamping the binding wire. During the process, the pressure sensor 61 of the pressure detection platform 6 detects the clamping pressure in real time. When the pressure reaches the preset value, the microprocessor controls the telescopic rod to stop extending and self-lock. After binding starts, the connecting seat 41 rotates with the rotating seat 22, and the clamping plate 43 drives the binding wire to wrap around the power cable synchronously. After binding is completed, the microprocessor controls the telescopic rod to retract, the clamping plate to reset, and the operator removes the remaining binding wire from the clamping groove. The microprocessor presets the clamping pressure threshold according to the diameter of the binding wire and realizes closed-loop pressure control through the feedback signal of the pressure sensor 61. When the pressure deviation exceeds the threshold, the extension amount of the electric telescopic rod is adjusted. The telescopic rod overload protection mechanism is set. When the working current exceeds 1.2 times the rated current, the machine stops immediately and an alarm is triggered on the control panel to prevent the binding wire from being broken due to excessive clamping.

[0033] Preferably, in any of the above solutions, the binding and fixing block 5 includes a pneumatic telescopic rod 51 connected to a microprocessor signal and a clamping plate 52 for pressing the binding wire. The pneumatic telescopic rod 51 is fixedly installed inside the connecting seat 41, and a clamping plate 52 located on one side of the connecting seat 41 is fixedly installed at one end of the pneumatic telescopic rod 51. The clamping plate 52 is configured as an L-shaped structure.

[0034] The above technical solution is adopted: the pneumatic telescopic rod 51 (miniature cylinder) of the binding and fixing block 5 is fixed inside the connecting seat 41 (perpendicularly distributed with the electric telescopic rod 42), and is connected to the microprocessor signal through a solenoid valve to achieve rapid extension and retraction. The L-shaped clamping plate 52 is fixed to the output end of the pneumatic telescopic rod 51 and can move outward of the connecting seat 41. Through cooperation with the side wall of the connecting seat, it presses and fixes the other end of the binding wire that passes around the power cable. The high thrust of the pneumatic telescopic rod 51 can meet the pressing requirements of the binding wire, ensuring... The binding wire remains secure during rotation and winding. The rapid response time synchronizes with the engagement action of the binding reference seat 4, ensuring no impact on overall binding efficiency. The L-shaped structure design allows the pressure plate 52 to conform to the surface of the circular power cable, preventing damage to the cable during pressing. The inner silicone pad increases the coefficient of friction with the binding wire and cable, preventing the binding wire from shifting after pressing and buffering the pressing force to avoid damaging the coating of the binding wire. The detachable connection between the pressure plate 52 and the pneumatic telescopic rod 51 facilitates subsequent replacement of worn silicone pads.

[0035] The pneumatic telescopic rod 51 is based on Pascal's principle. A miniature air pump built into the fixed handle bracket 1 generates compressed air. When the microprocessor-controlled solenoid valve opens, compressed air enters the cylinder chamber, pushing the piston rod out and moving the pressure plate 52. When the solenoid valve closes, the cylinder exhausts air, and the piston rod retracts under the action of the return spring. The L-shaped pressure plate 52 utilizes the lever principle to convert the axial thrust of the pneumatic telescopic rod into a vertical pressing force on the binding wire. The elastic deformation of the silicone pad fills the gap between the binding wire and the pull wire, forming a tight fit and further improving the fixing effect. The connecting seat 41 provides an installation reference for the pneumatic telescopic rod 51, ensuring its positional accuracy with the electric telescopic rod 42 and avoiding interference with the clamping plate 43 during pressing. After one end of the binding wire is fixed by the clamping plate 43, the operator loops the other end around the electric pull wire and places it into the pressing area between the pressure plate 52 and the connecting seat 41, ensuring the wire is directly below the silicone pad. When the screen maker clicks the "Pressure and Fix" button, the microprocessor controls the solenoid valve to open, and the micro air pump supplies air to the pneumatic telescopic rod 51. The piston rod extends and drives the clamping plate 52 to move towards the binding line. The silicone pad gradually adheres to the line and the pull line. The pressure sensor 61 of the pressure detection platform 6 provides real-time feedback on the pressing pressure. When the pressure reaches the preset value, the microprocessor controls the air pump to stop supplying air, and the solenoid valve remains open to maintain the pressure. During the binding rotation, the clamping plate 52 rotates synchronously with the connecting seat 41, always applying a stable pressing force to the binding line. After binding is completed, the microprocessor controls the solenoid valve to release air, the pneumatic telescopic rod retracts, the clamping plate resets, and the operator removes the remaining binding line. The microprocessor controls the air pump to start and stop through the feedback signal from the pressure sensor 61, adopting a "segmented air supply" strategy (high flow rate air supply in the initial stage, and low flow rate fine adjustment when approaching the preset pressure). The micro air pump adopts an intermittent working mode to avoid continuous operation causing excessive temperature rise.

[0036] Preferably, in any of the above embodiments, the pressure testing station 6 includes a pressure sensor 61 connected to a microprocessor signal and a pressure-bearing extrusion plate 62. The pressure sensor 61 is fixedly installed inside the connecting seat 41, and the extrusion plate 62 located inside the connecting seat 41 is fixedly installed at the detection end of the pressure sensor 61.

[0037] The above technical solution employs two piezoelectric pressure sensors 61 on the pressure testing platform 6, which are fixed inside the connecting base 41 at positions corresponding to the biting groove and the pressing area, respectively. They are connected to the microprocessor via signal lines to collect the biting pressure and pressing pressure of the binding wire in real time. The extrusion plate 62 is fixed to the detection end of the pressure sensor 61, exposed in the biting groove and pressing area, and in direct contact with the binding wire. It converts the local pressure of the binding wire into a uniform surface pressure and transmits it to the sensor. The high precision and fast response of the pressure sensor 61 can accurately capture subtle changes in the biting pressure and pressing pressure, avoiding loosening of the binding wire during rotation due to insufficient pressure or damage to the binding wire due to excessive pressure. The two sensors work independently and can monitor the pressure of the biting and pressing stages separately, which facilitates the microprocessor to adjust the movement of the electric telescopic rod 42 and the pneumatic telescopic rod 51 accordingly. The smooth surface of the extrusion plate 62 can avoid scratching the surface of the binding wire, while increasing the contact area with the binding wire, eliminating detection errors caused by local protrusions in the binding wire, and improving the accuracy of pressure data.

[0038] Pressure sensor 61 is based on the piezoelectric effect. When the binding wire applies pressure to the sensor through the compression plate 62, the piezoelectric crystal inside the sensor generates an electric charge. This charge is converted into a voltage signal by a charge amplifier, and then converted into a digital signal by an AD converter, which is then transmitted to the microprocessor. The compression plate 62 is based on the principle of uniform force transmission. By increasing the contact area, it converts the line contact pressure of the binding wire into surface contact pressure, avoiding pressure concentration that could lead to sensor detection deviation. The microprocessor processes the signals from the two sensors independently and compares them with preset pressure thresholds to achieve independent control of the biting and pressing stages. After the binding wire is placed in the biting groove or pressing area, it comes into direct contact with the compression plate 62. The electric telescopic rod 42 or the pneumatic telescopic rod 51 pushes the biting plate 43 to press it down. As plate 52 moves, the pressure of the binding line on the compression plate 62 gradually increases. The compression plate transmits the pressure to the pressure sensor 61, which sends pressure data to the microprocessor. The microprocessor judges in real time whether the pressure is up to standard. If the clamping pressure does not reach the preset value, it controls the electric telescopic rod to continue extending. If the clamping pressure exceeds the preset value, it controls the pneumatic telescopic rod to retract appropriately. During the binding process, the sensor continuously monitors the pressure. If the pressure drops by more than 2N due to the slippage of the binding line, the microprocessor immediately flashes an alarm on the control screen 8 and pauses the binding action. After the binding is completed, the sensor pressure data returns to zero, waiting for the next detection. The microprocessor sets independent pressure thresholds and alarm ranges for the two pressure sensors 61 and uses a Kalman filter algorithm to process the sensor data and remove pressure noise caused by vibration.

[0039] Preferably, in any of the above embodiments, the adjusting locking rod 7 includes a rotating disk 71 that provides support, a fastening spring 72 that provides supporting force, and a locking slide rod 73 that engages with the rotating seat 22. The rotating disk 71 is rotatably connected to the inside of the fixed handle frame 1. One end of the rotating disk 71 is fixedly installed with the fastening spring 72 located inside the fixed handle frame 1. One end of the fastening spring 72 is fixedly installed with the locking slide rod 73 that moves inside the fixed handle frame 1. One end of the locking slide rod 73 is provided with a positioning boss that is movably connected to the inside of the fixed handle frame 1.

[0040] The above technical solution is adopted as follows: the rotating disk 71 (ABS plastic material) of the adjusting locking rod 7 is rotatably connected to the side wall of the fixed handle frame 1, which is convenient for the operator to rotate manually. The fastening spring 72 is fixed to one end of the rotating disk 71 and is located inside the frame. It provides the return spring force for the locking slide rod 73. The locking slide rod 73 is fixed to the other end of the fastening spring 72 and can slide along the guide hole inside the frame. The locking head can be locked into the locking hole in the circumferential direction of the rotating seat 22 to realize the locking and unlocking of the rotating seat. The ABS material is lightweight and does not increase the overall burden of the device. The high elastic coefficient of the fastening spring 72 ensures that the spring force is sufficient when compressed, pushing the locking slide rod 73 to tightly lock into the locking hole, preventing the rotating seat 22 from rotating accidentally in the automatic binding mode. The positioning boss design at one end of the locking slide rod 73 is easy to operate and facilitates manual unlocking.

[0041] The adjusting locking lever 7 is based on the principle of spring elastic return. When the rotating disk 71 is rotated clockwise, the disk compresses the fastening spring 72. The spring stores elastic potential energy, which drives the locking slide lever 73 to move inward into the frame. The locking head disengages from the locking hole of the rotating seat 22, and the rotating seat can rotate freely. When the rotating disk 71 is rotated counterclockwise, the spring releases elastic potential energy, pushing the locking slide lever 73 outward into the frame. The locking head engages with the nearest locking hole, and the rotating seat is locked (manual binding mode). The clearance fit between the locking hole and the locking head ensures smooth engagement and limits the radial and circumferential displacement of the rotating seat, achieving reliable locking. The guide hole provides a sliding reference for the locking slide lever 73, ensuring linear movement of the slide lever and preventing the locking head from shifting and failing to align with the locking hole. When switching to automatic binding mode, the operator... Pinch the positioning boss with your fingers and rotate it clockwise. The rotating disk compresses the fastening spring 72, and the locking slide bar 73 moves inward along the guide hole. The clamp head completely disengages from the locking hole of the rotating seat 22. After the microprocessor detects that the rotating seat is unlocked, it allows the drive motor 21 to start. When switching to manual binding mode, rotate the positioning boss counterclockwise. The spring returns to its original position and pushes the locking slide bar 73 outward. The clamp head automatically engages with the nearest locking hole, and the rotating seat is locked. The operator can hold the fixed handle frame 1 and manually rotate the frame to wind the binding line. If it is necessary to pause during binding, rotate the rotating disk 71 to engage the clamp head with the locking hole and lock the rotating seat to prevent binding deviation caused by inertial rotation. After binding is completed, if the automatic mode is still needed, simply rotate the rotating disk clockwise again to unlock it.

[0042] The working principle of the auxiliary device for binding power cables according to this utility model is as follows: First, place one end of the binding wire into the engagement groove of the binding reference seat 4. Send a command through the control panel 8, and the microprocessor drives the electric telescopic rod 42 to push the engagement plate 43 to clamp the binding wire. The pressure sensor 61 of the pressure detection table 6 detects the pressure in real time. After reaching the preset threshold, the telescopic rod self-locks. Then, pass the other end of the binding wire around the power cable and place it into the pressing area of ​​the binding fixing block 5. The microprocessor controls the pneumatic telescopic rod 51 to push the L-shaped pressing plate 52 to press. After the pressure sensor 61 confirms that the pressure is up to standard, it maintains the pressing state. If automatic binding is selected, rotate the rotating disk 71 of the adjusting locking rod 7 clockwise to compress the fastening spring 72 and make the locking slide rod 73 disengage from the locking hole of the rotating seat 22. The microprocessor starts the drive motor 21 of the binding torsion seat 2. The coupling drives the rotating seat 22 to rotate, which in turn drives the connecting seat 41, the biting plate 43, and the pressing plate 52 to rotate. The binding wire is wound around the pull wire. The dynamic torque sensor 3 monitors the motor torque in real time. The data is transmitted to the microprocessor and displayed on the control screen 8. When the torque reaches the preset value or the number of winding turns reaches the standard, the motor stops. The pressure detection platform 6 continuously provides pressure feedback during binding. An alarm is triggered when there is an abnormality. When manual mode is required, the rotating disk 71 is turned counterclockwise. The spring resets and pushes the locking slide 73 into the locking hole, locking the rotating seat 22 for manual operation. The fixed handle frame 1 provides stable support throughout the process. The control screen 8 displays the torque, pressure, and power simultaneously. After binding is completed, the telescopic rod resets, and the data is stored in the microprocessor, completing the entire binding process.

[0043] Compared with the prior art, the present invention has the following advantages: 1. A binding reference seat 4 and a binding fixing block 5 are set up to engage and fix the binding wire. The two ends of the binding wire can be joined and fixed by the binding reference seat 4 and the binding fixing block 5. The binding torsion seat 2 drives the binding reference seat 4 and the binding fixing block 5 to quickly bind the binding wire after engagement. At the same time, the dynamic torque sensor 3 is used to detect the binding torque, which facilitates accurate judgment of the binding degree, improves the binding accuracy, and enhances the binding convenience.

[0044] 2. An adjustable locking rod 7 is installed inside the fixed handle frame 1 to lock and control the binding torsion seat 2. By locking the binding torsion seat 2, the manual binding state can be switched. The auxiliary device can be switched between automatic binding and manual binding according to the binding needs, thereby improving the convenience of using the auxiliary device.
