[0030] Reference Figures 1 to 4A low-voltage overhead line laying auxiliary device includes a support mechanism 100 and a wire limiting and guiding mechanism 200. The support mechanism 100 is used to support the ground. The wire limiting and guiding mechanism 200 includes a base 210 and a pair of limiting and guiding components 220. The base 210 is located at the upper end of the support mechanism 100. The pair of limiting and guiding components 220 are arranged on the left and right sides of the base 210, forming a wire passage between the pair of limiting and guiding components 220. The wire passage is used for the power supply line to pass through. The limiting and guiding component 220 includes a lifting component 221, a support wheel 222, and a limiting wheel 223. The lifting component 221 is located on the base 210, and the support wheel 222... 2. A pair of limit wheels 223 are rotatably mounted on the lifting assembly 221 with their rotation axis set along the front-back direction. The rotation axis of the limit wheels 223 is perpendicular to the front-back direction. The two limit wheels 223 are respectively set at the two ends of the support wheel 222 along the axial direction and extend upward relative to the support wheel 222. A line-laying position is formed between the two limit wheels 223 and the support wheel 222. The lifting assembly 221 can be raised and lowered to raise and lower the position of the support wheel 222 and the limit wheels 223 as a whole.

[0031] During operation, the support mechanism 100 is placed on the ground below the overhead power line, and the power line limiting and guiding mechanism 200 is placed on the upper side of the support mechanism 100. The lifting components 221 of the two pairs of limiting and guiding components 220 are raised, allowing the overhead power line to pass through the crossing position formed between the limiting and guiding components 220. The power line to be pulled across is placed into the laying position on the limiting and guiding component 220, so that the power line is supported by the support wheel 222 and limited between the two pairs of limiting wheels 223. The height of the lifting components 221 is controlled to be sufficient to ensure that the height of the power line in the laying position is higher than the height of the crossing position. The wire is then pulled; at this point, the wire is confined between the limiting wheel 223 and the support wheel 222, isolated from the original wire. This eliminates the need for a protective layer on the original wire, and the wire to be pulled across will not rub against the existing wire. This reduces workload, avoids contact friction between wires, and prevents the risk of mutual pulling and tugging, improving work efficiency and safety. At the same time, the wire contacts the rotatable support wheel 222 and limiting wheel 223, which also reduces friction and improves the efficiency of wire pulling and releasing, further enhancing work efficiency.

[0032] In this embodiment, the lifting assembly 221 is configured to be controlled to lift from the ground, thereby facilitating operation by the operator without the need for climbing up and down.

[0033] In this embodiment, the support mechanism 100 is a ladder, with a support platform 110 at the top. The support platform 110 supports the base 210. The use of a ladder for the support mechanism 100 is convenient for on-site use and has low cost. It is conceivable that the support mechanism 100 is not limited to a ladder; for example, it could be other structures capable of providing support, such as a work vehicle with a lifting platform.

[0034] In some embodiments, the support platform 110 and the base 210 can be reinforced with fasteners, such as threaded fasteners or cable ties. In some embodiments, a clamping and fixing mechanism can also be provided on the base 210 to clamp and fix it to the support platform 110.

[0035] In this embodiment, the ladder is a telescopic ladder, which facilitates quick height adjustment. After a quick, approximate height adjustment, the lifting assembly 221 is used for more precise height adjustment to ensure that the wire is supported at a position higher than the original wire.

[0036] In this embodiment, a single limiting guide component 220 includes multiple support wheels 222 arranged in an arc shape, with their positions decreasing sequentially from the direction away from the wire guide position. Multiple pairs of limiting wheels 223 are arranged along the arrangement direction of the support wheels 222. This structure provides arc-shaped support and limiting of the wire, preventing excessive bending of the wire during the wire laying and pulling process.

[0037] In this embodiment, the lifting assembly 221 is provided with a limiting wheel connecting shaft, and the limiting wheel connecting shaft corresponds one-to-one with the limiting wheel 223. The support wheels 222 are spaced apart, and the limiting wheel connecting shaft is located between adjacent support wheels 222. The limiting wheel 223 is installed on the upper end of the corresponding limiting wheel connecting shaft. This structure utilizes the space between the support wheels 222 to set the limiting wheel connecting shaft, thereby facilitating the installation of the limiting wheel 223, resulting in a simple and compact structure.

[0038] In this embodiment, the lifting assembly 221 includes a lifting platform 2211, a wheel connecting seat 2212, and a lifting drive structure 2213. The lower end of the lifting platform 2211 is disposed on the base 210, the wheel connecting seat 2212 is connected to the upper end of the lifting platform 2211, and the lifting drive structure 2213 is used to drive the lifting platform 2211 to lift. Support wheels 222 and limit wheels 223 are disposed on the wheel connecting seat 2212. The lifting platform 2211 includes a platform component 2211a, a first hinge rod 2211b, and a second hinge rod 2211c. The middle parts of rod 2211b and the second hinge rod 2211c are hinged together to form a cross-shaped hinge frame. The upper ends of the second hinge rod 2211c and the first hinge rod 2211b are respectively hinged to the front and rear of the platform 2211a. The lower end of the first hinge rod 2211b is hinged to the base 210. The lower end of the second hinge rod 2211c is movable back and forth relative to the base 210. The lifting drive structure 2213 is configured as a first front and rear driver, which drives the lower end of the second hinge rod 2211c to move back and forth. When lifting adjustment is required, the lower end of the second hinge rod 2211c is driven to move back and forth by the first front and rear driver, thereby raising and lowering the cross-shaped hinge frame formed by the first hinge rod 2211b and the second hinge rod 2211c, thus realizing the overall raising and lowering of the lifting assembly 221. The above-mentioned lifting structure is simple, easy to implement, and the cross-shaped hinge frame provides stable structural support.

[0039] In this embodiment, the lifting drive structure 2213 includes a connecting rod 2213a, a drive screw 2213b, and a rotary driver 2213c. The drive screw 2213b is arranged front and rear and pivotally connected to the base 210. The connecting rod 2213a is arranged left and right, and its left and right ends are respectively fixed to the lower ends of the two second hinge rods 2211c of the two corresponding pairs of lifting platforms 2211. A lead screw nut is provided in the middle of the connecting rod 2213a, and the lead screw nut is threadedly connected to the drive screw 2213b. The rotary driver 2213c is connected to the drive screw 2213b and is used to drive the drive screw 2213b to rotate. The rotary driver 2213c is configured to be controllable from the ground. The rotary actuator 2213c drives the drive screw 2213b to rotate. The rotating drive screw 2213b adjusts the position of the lead screw nut on the drive screw 2213b, thereby causing the lower ends of the corresponding pairs of second hinge rods 2211c to move back and forth, realizing the raising and lowering of the cross-shaped hinge frame. The above-described lifting drive structure 2213 is simple in structure, and the screw-driven structure has a self-locking feature, thus providing stable support. It is conceivable that the first front and rear actuator is not limited to the above structure; for example, an electric push rod or other structures capable of driving the lower ends of the second hinge rods 2211c to move back and forth could also be used.

[0040] In this embodiment, the rotary actuator 2213c can be a manually driven mechanism. The rotary actuator 2213c includes a drive wheel and a drive belt. The drive wheel is fixed to the drive screw 2213b, and the drive belt is sleeved on the drive wheel. The drive belt can extend to the ground. Construction workers can pull the drive belt to rotate the drive wheel, thereby driving the drive screw 2213b to rotate, thus raising and lowering the lifting platform 2211. Because a drive belt extending to the ground is used, control can also be achieved from the ground. In some embodiments, the drive belt can also be replaced by a flexible shaft. One end of the flexible shaft is connected to the drive wheel, and the other end extends to the ground and is connected to a drive handwheel. The drive handwheel rotates the drive wheel via the flexible shaft, thereby driving the drive screw 2213b to rotate. It is conceivable that the rotary actuator 2213c can also be a motor. The output shaft of the motor is connected to the drive screw 2213b. The connection method can be a direct coaxial connection or a transmission mechanism such as a gear set. The motor is connected to a remote control circuit board, thus enabling control from the ground.

[0041] It is conceivable that the lifting platform 2211 is not limited to the above-mentioned structure. For example, it can adopt existing lifting equipment capable of lifting, such as some scissor lift devices, and select a model that can be remotely controlled, thereby realizing lifting control on the ground.

[0042] In this embodiment, the wheel connecting seat 2212 is movably mounted on the lifting platform 2211 to allow the corresponding pairs of wheel connecting seats 2212 to move closer and further apart. The wire limiting and guiding mechanism 200 also includes a wheel seat drive mechanism, which is mounted on the lifting platform 2211 and used to drive the wheel connecting seats 2212 to move left and right. Corresponding wire guide shells 2212a are respectively provided on opposite sides of the corresponding pairs of wheel connecting seats 2212. When the corresponding pairs of wheel connecting seats 2212 approach each other, the corresponding two wire guide shells 2212a enclose and form a wire passage for the power supply wire to pass through. The wheel seat drive mechanism is configured to be controllable from the ground. With the above structure, in some operations, by driving the corresponding two wheel connecting seats 2212 closer together, the wire passing through can be clamped in the internal wire passage by the two wire guide shells 2212a, thus providing more comprehensive protection. In actual operation, the two wire guide shells 2212a can clamp the uppermost wire, or a larger wire guide shell 2212a can be used to protect more than one wire. The specific configuration can be made according to the actual situation.

[0043] In this embodiment, the wheel connecting seat 2212 is slidably mounted on the corresponding lifting platform 2211 in the left-right direction. The wheel seat drive mechanism can be an electric push rod or a motor-driven screw slide mechanism mounted on the lifting platform 2211. The wheel connecting seat 2212 and the moving parts of the wheel seat drive mechanism are connected. In this embodiment, the wheel seat drive mechanism can be controlled remotely via electrical control, allowing for operation from the ground.

[0044] In this embodiment, the limiting guide assembly 220 is equipped with an electric traction structure. This electric traction structure is used to pull the wire through the laying position from left to right, and is configured to be controllable from the ground. Using this structure, the electric traction structure can pull the wire, assisting in the threading operation, improving efficiency, and reducing the labor intensity of workers.

[0045] In this embodiment, each limiting wheel 223 is movable in the forward and backward direction. A pair of limiting wheels 223 can approach and move away from each other, forming a wire clamping position when they approach. The electric traction structure includes a clamping driver for driving the pair of limiting wheels 223 to approach and move away from each other, and a traction driver for driving at least one of the pair of limiting wheels 223 to rotate. The clamping driver and the traction driver are configured to be controllable from the ground. When a wire needs to be pulled, the clamping driver drives the pair of limiting wheels 223 to approach, thereby clamping the passing wire. Then, the traction driver drives the limiting wheels 223 to rotate, pulling the wire forward through friction. The above-described electric traction structure, utilizing the limiting wheels 223 as traction wheels, is simple in structure and easy to implement.

[0046] In one embodiment, the traction driver may be a motor, and the output shaft of the motor is connected to the limiting wheel 223 for transmission, thereby driving the limiting wheel 223 to rotate.

[0047] In this embodiment, the position of the pair of limiting wheels 223 clamping the wire can be controlled and adjusted by a clamping position adjuster. The electric traction structure also includes pressure sensors for detecting the pressure of the wire on the pair of limiting wheels 223. The pressure sensors are connected to the controller and the clamping position adjuster. When the pressure sensor detects that the pressure of one of the pair of limiting wheels 223 is greater than the pressure of the other, the controller controls the clamping position adjuster to adjust the position of the two limiting wheels 223 clamping the wire towards the limiting wheel 223 with greater pressure. With the above settings, when pulling the wire, if the wire is biased towards one limiting wheel 223, the pressure on that limiting wheel 223 is greater than that on the other limiting wheel 223. The controller controls the clamping position adjuster to adjust the position of the two limiting wheels 223 clamping the wire towards that limiting wheel 223, thereby preventing the wire from bending excessively.

[0048] In this embodiment, the clamping driver can be a second front-rear driver corresponding one-to-one with the pair of two limiting wheels 223. The limiting wheels 223 are movably disposed in the lifting assembly 221 in the front-rear direction. Specifically, the limiting wheel connecting shaft used to connect and install the limiting wheels 223 can be slidably disposed in the wheel connecting seat 2212. The second front-rear driver is connected to the corresponding limiting wheel 223 and is used to drive the corresponding limiting wheel 223 to move back and forth. When it is necessary to clamp the traction wire, the two second front-rear drivers corresponding to the pair of two limiting wheels 223 drive the pair of two limiting wheels 223 to move closer together. When the clamping driver uses the above-mentioned second front-rear driver, the clamping position adjuster includes the pair of the above-mentioned second front-rear drivers. When it is necessary to adjust the position of the limiting wheel 223 clamping the wire, the pair of two second front-rear drivers drive the corresponding pair of two limiting wheels 223 to move in the same direction, thereby realizing the adjustment of the clamping position of the wire. In other embodiments, the clamping position adjuster is not limited to the above-described implementation. For example, the clamping driver and the corresponding pair of limiting wheels 223 are both mounted on the front and rear sliding seats, which are slidably mounted on the wheel connecting seat 2212. The clamping position adjuster can be a third front and rear driver, which is mounted on the wheel connecting seat 2212 and connected to the front and rear sliding seats to drive the front and rear sliding seats to move back and forth, thereby also achieving adjustment of the clamping position of the wire. In the above-described implementation, the second and third front and rear drivers can be electric push rods, linear motors, motor lead screw slides, etc., and can be configured according to actual conditions.

[0049] In some embodiments, the clamping driver is not limited to using a second front and rear driver that corresponds one-to-one with the pair of limit wheels 223, for example, using some electric clamping drivers, etc.

[0050] In some embodiments, the electric traction structure is configured for ground control. Specifically, the clamping driver and the traction driver can be connected to a remote control circuit board for remote control. Alternatively, in some embodiments, a sufficiently long wire is used to connect the clamping driver and the traction driver, extending to the ground and connecting to a control box, transmitting control signals via the wire to achieve control. Similarly, if a clamping position adjuster is added, ground control can also be achieved by using a remote control circuit board or a wire. Of course, in some embodiments, a purely mechanical mechanism, such as a flexible shaft or a transmission belt, can also be used to achieve ground control.

[0051] In this embodiment, both of the paired limiting guide components 220 are equipped with the aforementioned electric traction structure. When pulling the wire, the electric traction structures on the paired limiting guide components 220 can operate simultaneously, thus ensuring that the wire can be pulled at both the entry and exit points, resulting in a good traction effect. Of course, in some embodiments, an electric traction structure can also be provided on a single limiting guide component 220 to complete the wire pulling task.

[0052] In other embodiments, the electric traction structure is not limited to the structure described above. For example, the electric traction structure includes an electric telescopic device connected to the lifting assembly 221 and equipped with a telescopic end that can extend and retract left and right. The telescopic end is connected to an electric gripper. During wire threading, the wire passes through the support wheel 222 and the limiting wheel 223 while also passing through the electric gripper. When electric traction is required, the electric gripper first grips the wire, and then the electric telescopic device drives its telescopic end to extend and retract in the direction where the wire needs to be pulled. Then, the electric gripper releases the wire, and the electric telescopic device drives its telescopic end to return to its original position. This process is repeated to continuously pull the wire in the direction where it needs to be pulled. Using the above-described electric traction structure, the entire length of the wire is not rolled, making it less prone to slippage, and it is easy to adapt to wires of different specifications. In the above embodiments, the electric telescopic device can be a first electric telescopic rod, one end of which is hinged to the lifting assembly 221. The hinge axis is set along the front-to-back direction, and the first electric telescopic rod extends away from the wire-passing position. The electric traction structure also includes an electric angle adjuster for driving the first electric telescopic rod to rotate and adjust its angular position relative to the lifting assembly 221. With the above further improvement, when the first electric telescopic rod extends and retracts to pull the wire, the electric angle adjuster can drive the first electric telescopic rod to adjust its angular position, thereby adjusting the pulling angle according to the actual working conditions, improving wire-threading efficiency and avoiding excessive bending of the wire. The electric angle adjuster can be a second electric telescopic rod, one end of which is hinged to the lifting assembly 221, and the other end is hinged to a sliding seat. The sliding seat is slidably disposed on the first electric telescopic rod, thereby forming a linkage slider mechanism. When the second electric telescopic rod extends and retracts, it can drive the first electric telescopic rod to swing and achieve angle adjustment. In other embodiments, the electric angle adjuster can also be a motor, which drives the first electric telescopic rod to rotate and adjust the angle. It is understood that there are many other structures in the art that allow for angle adjustment of components, and those skilled in the art can configure them according to the actual situation.

[0053] In this embodiment, a camera mechanism 300 is also included. The camera mechanism 300 is disposed on the wire limiting and guiding mechanism 200 and is used to capture images of the wire crossing and laying positions and transmit them to the smart terminal 400. By setting up the camera mechanism 300, the operation can be captured, especially when adjusting the height of the lifting and lowering limiting and guiding component 220, allowing for more accurate adjustments. In this embodiment, the camera mechanism 300 specifically includes a camera and a camera communication circuit board. The camera is disposed on the wire limiting and guiding mechanism 200 and connected to the camera communication circuit board, which is used to transmit the images captured by the camera to the smart terminal 400. In some embodiments, the smart terminal 400 can be a mobile phone, tablet computer, laptop computer, etc.

[0054] In this embodiment, a wire threading travel detection mechanism is also included. This mechanism is disposed within the wire limiting and guiding mechanism 200 and is used to detect the travel distance of the wire being pulled. The wire threading travel detection mechanism communicates with the smart terminal 400 to display the detected travel distance information. By setting up the wire threading travel detection mechanism, the travel distance of the wire being pulled can be displayed, thereby facilitating the calculation of the wire length.

[0055] In this embodiment, a wire threading speed detection mechanism is also included. This mechanism is disposed within the wire limiting and guiding mechanism 200 and is used to detect the speed at which the wire is pulled. The wire threading speed detection mechanism communicates with the smart terminal 400 to display the detected speed. By setting up the wire threading speed detection mechanism, the speed at which the wire is pulled can be displayed, thereby facilitating control during operation.

[0056] The aforementioned threading stroke detection mechanism and threading speed detection mechanism can be implemented using an encoder. The encoder is connected to a controller and is equipped with a pressing structure, such as a pressure roller or pressure wheel, that presses the wire against the support wheel 222 or the limit wheel 223. When the wire is pulled, it drives the corresponding support wheel 222 or limit wheel 223 to rotate synchronously. The encoder and support wheel 222 or limit wheel 223 are correspondingly configured and used to detect the number of rotations. The number of rotations detected by the encoder is converted into stroke and speed information by the controller. In embodiments using an electric traction structure, the wire is clamped between the limit wheels 223 and pulled by the limit wheels 223. In this case, the traction driver can be a servo motor, and the threading stroke detection mechanism and threading speed detection mechanism can be stroke or speed sensors integrated into the servo motor. In other embodiments, the threading stroke detection mechanism and threading speed detection mechanism can also use a vision detection device. Utilizing regularly spaced markings on the wire, the vision detection device indirectly calculates the stroke and speed of the pulled wire by photographing and calculating the interval between the markings.

[0057] In this embodiment, a live-line detection mechanism is also included. This mechanism is disposed within the wire limiting and guiding mechanism 200 and is used to detect the electric field strength around the wire limiting and guiding mechanism 200. The live-line detection mechanism communicates with the smart terminal 400 to display the detected electric field strength. By setting up the live-line detection mechanism, the electric field strength can be detected, alerting operators to the danger. In this embodiment, the live-line detection mechanism can employ an electric field sensor.

[0058] In the above embodiments, the threading stroke detection mechanism, threading speed detection mechanism, and live-line detection mechanism communicate with the intelligent terminal 400. The intelligent terminal 400 can be configured as a control screen with a control host computer. The intelligent terminal 400 can also uniformly control various components that require electric remote control, thereby facilitating unified operation and monitoring. The intelligent terminal 400 can be fixed to the support mechanism 100 or set up independently, and communicate wirelessly.

[0059] In this embodiment, the threading stroke detection mechanism, the threading speed detection mechanism, and the live-line detection mechanism can also communicate with other information display mechanisms to display information. For example, the live-line detection mechanism can display the situation of electric field exceeding the limit through a warning light, while the detection of speed and stroke can be displayed through a display screen.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
