Description

Technical Field

[0001] The present application relates to the field of power tower cable maintenance, and in particular to an auxiliary lifting device and control system for power tower maintenance. Background Art

[0002] Power towers are commonly found in urban and rural areas. They are tower structures used to support and erect transmission lines in power systems. They are used to support high-voltage wires in overhead transmission lines and ensure a safe distance between conductors, conductors and towers, conductors and lightning conductors, and between conductors crossing the ground.

[0003] Mainly, the power tower is divided into two parts: tower legs and supporting steel poles. The tower legs are vertically inclined steel poles at the four corners of the tower body, with the bottom connected to the ground and the top extending to the top of the tower. The two ends of the supporting steel poles are connected between multiple tower legs at an inclined and horizontal angle to reinforce the tower legs. Regular maintenance of power towers and cables is essential, as it not only ensures the stable operation of the power system and the continuity of power supply, but also helps prevent accidents and disasters and prolong the service life of equipment. Most of the existing power tower maintenance requires technicians to carry special equipment to climb the tower. Regarding the above-mentioned related technologies, the inventor believes that there are certain risks for technicians to carry heavy objects during the climbing process. Therefore, installing an auxiliary lifting device on the tower body for technicians to place heavy objects during the climbing process will increase the climbing speed of technicians and reduce safety risks during the climbing process. Application Contents

[0004] In order to increase the climbing speed of technicians and reduce the safety risks during the climbing process, the present invention provides an auxiliary lifting device and a control system for power tower maintenance.

[0005] On the one hand, the present invention provides an auxiliary lifting device for power tower maintenance, which adopts the following technical solution: An auxiliary lifting device for power tower maintenance, comprising: The lifting wire is connected at the end to form a coil, and the coiled lifting wire is vertically wound around multiple tower legs to connect the two ends of the tower legs. Fixed pulleys are provided at both ends of the tower legs for rotating the coiled lifting wire; a lifting block is provided on the lifting wire; A lifting plate, one edge of which is mounted on the lifting block and is arranged horizontally; A driving assembly is arranged at the bottom end of the tower leg and corresponds to the fixed pulley, and is used to connect the driving member to drive the lifting wire to rotate; The tower leg is provided with a lifting groove corresponding to the lifting wire, the lifting groove is parallel to the length direction of the tower leg, the width is adapted to the size of the lifting wire, and the lifting wire is arranged in the lifting groove; The width of the top of the lifting groove is smaller than the width of the groove body, so that the lifting wire is clamped in the lifting groove.

[0006] By adopting the above technical solution, the tower legs are the main structure supporting the tower body. In the above solution, the lifting plate is the main structure for technicians to carry heavy objects when climbing the iron tower. The lifting plate is horizontally arranged. The technicians place the heavy objects on the lifting plate before climbing the power iron tower. Driven by the driving parts and driving components, the lifting plate rises as the technicians climb. The technicians can control the lifting speed and lifting distance of the lifting plate to adapt to the maintenance needs of the technicians corresponding to the power iron tower. Specifically, the lifting wire is the main structural member that drives the lifting plate to maintain horizontal lifting. The lifting wire is coiled and flexibly rotated through the fixed pulleys at both ends of the tower leg. The driving member is connected to one of the pulleys, and the fixed pulley is used as the active pulley, and the other fixed pulley is the passive pulley. The rotation of the active pulley drives the lifting wire coil to rotate as a whole, and further drives the lifting block fixed on the lifting wire body to move, and the lifting block then drives the lifting plate to move. In actual applications, attention should be paid to the connection stability between the lifting plate and the lifting block; In addition, in order to further stabilize the transmission connection, a lifting groove is opened on the tower leg. The lifting groove can be opened on the surface of the tower leg or inside the tower leg. It is actually recommended to open it inside the tower leg. The tower body is supported by multiple supporting steel rods to maintain high stability and high load capacity. The surface of the tower leg is flush with the top of the lifting groove, and the two opposite side edges of the top of the lifting groove extend horizontally toward each other, narrowing the opening width of the lifting groove on the surface of the tower leg and limiting the lifting wire installed inside the lifting groove. In other words, after the lifting wire is installed in the lifting groove when installing the power tower, a flat plate of preset width needs to be welded to the top of the lifting groove to reduce the width of the lifting groove and firmly limit the lifting wire in the lifting groove; in actual application, the width of the connection part between the lifting plate and the lifting block should be adapted to the opening width of the top of the lifting groove.

[0007] Optionally, the driving assembly includes a coupling disc, and the coupling disc is connected to and concentric with the fixed pulley; The driving member comprises a driving motor, the end of the rotating shaft of the driving motor is provided with the coupling disc, and the two coupling discs are connected to connect the driving motor to the fixed pulley.

[0008] By adopting the above technical solution, the driving motor rotates under the control of the technicians, and the two coupling discs form a traditional coupling, connecting the rotating shaft of the driving motor with the axle of the fixed pulley, and the rotation of the driving motor drives the fixed pulley to rotate synchronously; Furthermore, the drive motor in the above scheme is a servo motor. The drive motor is in a state that is easy to disassemble and assemble, and is generally transported by technical personnel. Before the maintenance work begins, the drive motor is connected to the fixed pulley through a coupling disk. After the maintenance work is completed, the drive motor is disassembled to separate it from the fixed pulley and keep the motor away from the high-voltage transmission line.

[0009] Optionally, a fixing block adapted to the lifting slot is formed on one side edge of the lifting plate close to the lifting block, and the fixing block is connected to the lifting block so that the lifting plate is fixed to the lifting block.

[0010] By adopting the above technical solution, the fixed block is the part connecting the lifting plate and the lifting block, and the width of the fixed block needs to adapt to the slot top width of the lifting slot, that is, the fixed block can extend into the lifting slot and fix the lifting block to fix the lifting plate and the lifting block.

[0011] Optionally, a support block is hinged on the bottom side of the lifting plate, and the support block is tilted and connected to the bottom end of the lifting block to support the lifting plate horizontally.

[0012] By adopting the above technical solution, the support block is used to form a stable triangular structure with the fixed block and the lifting plate, and the lifting block is connected under the fixed block to support the lifting plate surface to be horizontal. Specifically, the support block should be the same size as the fixed block and can also be extended into the lifting slot to connect with the lifting block; Due to the tilt setting of the tower legs, the support block maintains a vertical tilt when sliding, and because the slope of the tower legs varies slightly in practice, the support block should rotate horizontally while maintaining the same tilt angle as the lifting plate. Therefore, the support block needs to be horizontally hinged to the bottom of the lifting plate surface to provide sufficient rotation margin; Furthermore, the spacing between one end of the support block and the fixed block connected to the lifting block should be consistent with the length of the lifting block, that is, the part of the fixed block extending into the lifting slot is connected to the top of the lifting block, and the part of the support block extending into the lifting slot is connected to the bottom of the lifting block. By fixing the two ends of the lifting block, the support block, the fixed block and the lifting block are fixedly connected, and the connection method of the ends of the lifting block is relatively stable.

[0013] Optionally, the tower leg is provided with an auxiliary groove on one side of the same side as the lifting groove, and the auxiliary groove is parallel to the lifting groove; An auxiliary block is slidably connected in the auxiliary groove, and the auxiliary block is connected to one side edge of the lifting plate.

[0014] By adopting the above technical solution, the auxiliary block plays a role in enhancing the stability of the lifting plate, the auxiliary groove is parallel to the lifting groove, and the auxiliary block in the auxiliary groove is connected to the lifting plate and keeps synchronous lifting with the lifting plate; The auxiliary block is not provided with any active driving member, that is, the auxiliary block is driven by the lifting plate and slides vertically with the lifting plate, and the sliding of the auxiliary block is limited by the auxiliary groove, which plays a role in guiding the sliding of the auxiliary block; Specifically, the auxiliary block can be connected to one side edge of the lifting plate through a flexible connection structure, such as an iron chain.

[0015] Optionally, a plurality of rollers are provided on inner walls on two opposite sides of the lifting groove, and the plurality of rollers are vertically evenly distributed at intervals, and the wheel surfaces of the rollers abut against the lifting wire.

[0016] By adopting the above technical solution, considering that multiple tower legs of the power tower are inclined, the lifting wire body is inclined. Therefore, during the rotation and transmission of the lifting wire coil, the friction force generated by the abutment and sliding of the lifting wire body and the lifting groove wall in the lifting groove will reduce the transmission efficiency of the lifting wire, that is, increase the power consumption of the driving motor. In turn, it is necessary to reduce the transmission loss of the lifting wire at the structural level, that is, widen the groove width of the lifting groove, and horizontally set a roller in the lifting groove, so that the wheel surface of the roller is adapted to and abuts the lifting wire, and rotates with the transmission of the lifting wire; In addition, under normal working conditions outside the maintenance cycle of the power tower, the contact between the roller wheel surface and the lifting wire can also limit the lifting wire, so that the straightness of the lifting wire is maintained within a normal range while the lifting wire remains tilted.

[0017] On the other hand, the control system of the auxiliary lifting device for power tower maintenance provided by the present invention adopts the following technical solution: A control system for an auxiliary lifting device for power tower maintenance, characterized in that it comprises a central processing module, a front-end control module, an input module, and a display module; The input module is connected to the central processing module to provide a command input channel; The central processing module receives the input instruction of the input module and sends the instruction to the front-end control module; The front-end control module receives the instruction of the central processing module and controls the operation of the driving motor; The display module displays the operating status of the drive motor.

[0018] Optionally, a test module is also included; The test module is connected to the drive motor to collect the shaft torque of the drive motor.

[0019] By adopting the above technical solution, the central processing module, front-end control module, input module, display module and test module constitute the main control system of the auxiliary lifting device for power tower maintenance, which is mainly used to control the operation of the drive motor; and the main modules related to the main control system are transported to the vicinity of the power tower by the technicians along with the drive motor before the start of the power tower maintenance work; Among them, the central processing module is preferably a common engineering computer to meet the data calculation and display needs of technicians. The central processing module stores instruction files and data calculation files. When the technician inputs data, the central processing module brings the calculation results into the corresponding calculation file according to the data type and displays them through the display module; the technician inputs the instruction file through the input module, and the central processing module runs the corresponding instruction file. According to the input instruction signal of the input module, the instruction file is converted into a corresponding control instruction to control the specific operation of the front-end control module; The front-end control module receives the control instructions from the central control module, and specifically executes and controls the operation of the drive motor according to the control instructions. The display module also displays the display control results of the front-end control module to the technicians, so that the technicians can understand them immediately. The test module is mainly used to test the load of the drive motor. After the technicians connect the drive motor to the fixed pulley through the coupling disk, they test the torque load of the drive motor. If the load is overweight, it means that the lifting wire inside the tower leg is too worn, and the operating tower leg should be maintained and replaced in time.

[0020] In summary, the present application includes at least the following three beneficial technical effects: 1. By connecting the ends of the lifting wire to form a coil and vertically winding it around multiple tower legs, and setting fixed pulleys at both ends of the tower legs, the lifting wire can rotate smoothly between the tower legs, thereby improving the safety and stability of the lifting process. This design effectively solves the problem of the lifting wire being easily offset or jumping when winding on the tower legs in the prior art, and improves the safety performance of the overall equipment; 2. By setting up a drive assembly and connecting the end of the drive motor's shaft to the coupling plate, and then connecting it to the fixed pulley, power transmission between the drive motor and the fixed pulley is achieved. This structure not only simplifies the operation steps and reduces the impact of human factors, but also greatly reduces the physical exertion caused by manual climbing, thereby significantly improving work efficiency and operational safety; 3. A lifting groove with a width that matches the size of the lifting wire is set on the tower leg and is parallel to the length direction of the tower leg, ensuring that the lifting wire always moves along the preset track, preventing lateral displacement caused by external forces, and further enhancing the reliability and service life of the system. At the same time, the design that the top width of the lifting groove is smaller than the width of the groove body allows the lifting wire to be more firmly connected to the groove, avoiding the risk of derailment; 4. The central processing module receives the instructions of the input module and sends them to the front-end control module to achieve precise control of the drive motor, improve the response speed and control accuracy of the system, and the display module displays the operating status of the drive motor in real time, which is convenient for operators to quickly understand the equipment status and improve the safety and efficiency of operations.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-6 This application is described in further detail.

[0029] On the one hand, the embodiment of the present application discloses an auxiliary lifting device for power tower maintenance. Figure 1An auxiliary lifting device for maintenance of an electric power tower is applied to the tower body 1 of the electric power tower, and a common electric power tower is used as an example. The tower body 1 is composed of four tower legs 2 at the four corners of the tower body 1 and multiple supporting steel rods 3 between the four tower legs 2. The four tower legs 2 are arranged to be inclined toward each other in a vertical plane. Multiple supporting steel rods 3 are arranged between the tower legs 2 to connect the tower legs 2 at both ends and support the tower legs 2, so that the tower legs 2 remain stable to withstand high loads. The inclination slopes of multiple tower legs 2 are the same, so that the tower body 1 is tapered and cylindrical as a whole, and in any cross section of the tower body 1, the four tower legs 2 form a square.

[0030] Reference Figure 1 The auxiliary lifting device is arranged on four tower legs 2, and one tower leg 2 is taken as an example for explanation.

[0031] Reference Figure 2 and Figure 3 , the opposite sides of the four tower legs 2, that is, the side of the tower leg 2 away from the center of the tower body 1, are provided with a lifting groove 21 and an auxiliary groove 22, and the lifting groove 21 and the auxiliary groove 22 are parallel to each tower leg 2; wherein, a lifting wire 211 is provided in the lifting groove 21, and the lifting wire 211 is connected end to end in a coiled shape and is placed in the lifting groove 21 along a direction parallel to the length of the tower leg 2; fixed pulleys 26 are provided at the top and bottom of the lifting groove 21, and the wheel surface of the fixed pulley 26 is parallel to The length direction of the tower leg 2 makes the coiled lifting wire 211 connected end to end fit with the fixed pulley 26, and relies on the two fixed pulleys 26 to tighten and transmit the power, and the two fixed pulleys 26 are respectively arranged corresponding to the top and bottom ends of the coiled lifting wire 211; in this embodiment, the fixed pulley 26 at the top of the tower leg 2 is arranged at the part outside the lifting groove 21, and the fixed pulley 26 at the bottom of the tower leg 2 is arranged at the bottom end inside the lifting groove 21, and the two fixed pulleys 26 rotate to drive the coiled lifting wire 211 to transmit.

[0032] Reference Figure 2 and Figure 3A horizontally arranged metal plate is fixed or welded to the bottom of the tower leg 2 at the height of the fixed pulley 26 on the adjacent side of the lifting slot 21. The metal plate is used to place the driving member. In this embodiment, the driving member is a driving motor 24. Specifically, a servo motor, a stepping motor, etc. can be selected. The rotating shaft of the driving motor 24 is concentric with the fixed pulley 26 at the bottom of the tower leg 2. The center of the wheel surface of the fixed pulley 26 is close to one side of the driving motor 24. A metal rod is formed corresponding to the rotating shaft of the driving motor 24. The metal rod penetrates the side wall of the tower leg 2, extends out of the side wall of the tower leg 2 and is connected to the rotating shaft of the driving motor 24. The metal rod of the fixed pulley 26 and the end of the rotating shaft of the driving motor 24 facing each other are formed with a vertically arranged coupling disc 25. The two coupling discs 25 are detachably fixed by bolts to form a coupling, and the rotating shaft of the driving motor 24 is fixed to the wheel center part of the fixed pulley 26. Thus, the rotating shaft of the driving motor 24 drives the fixed pulley 26 to rotate. When the lifting wire 211 is tightened by the two fixed pulleys 26, the fixed pulley 26 at the bottom of the tower leg 2 is driven by the driving motor 24 as a driving wheel to drive the coiled lifting wire 211.

[0033] Reference Figure 3 and Figure 4 On the inner walls of the two opposite sides of the lifting groove 21, multiple rollers 212 are vertically distributed along the length direction of the tower leg 2. The wheel surface of the roller 212 is in a curved shape, abutting against the lifting wire 211. The swing amplitude of the lifting wire 211 is limited by the abutment of the wheel surface, so as to prevent the lifting wire 211 from abutting against the inner wall of the lifting groove 21 during the transmission process, thereby wearing the lifting wire 211 and increasing the loss of the driving motor 24. In this embodiment, the roller 212 is arranged to replace the sliding friction in a synchronous rolling manner. A lifting block 213 is fixedly connected to the lifting wire 211, and the lifting block 213 is arranged in the lifting groove 21. The transmission of the lifting wire 211 drives the lifting block 213 to slide along the lifting groove 21. The shape and size of the lifting block 213 are adapted to the groove width of the lifting groove 21. The groove walls on the two opposite sides of the lifting groove 21 play the role of guiding and sliding limit.

[0034] Reference Figure 1 and Figure 2In order to limit the lifting block 213 and the lifting wire 211 inside the lifting slot 21 and prevent the lifting block 213 and the lifting wire 211 from escaping from the lifting slot 21, the top of the lifting slot 21, or the surface of the tower leg 2, extends toward the top of the lifting slot 21, shortening the width of the notch portion of the top of the lifting slot 21, so that the notch width of the lifting slot 21 is smaller than the width of the lifting block 213, and the lifting block 213 is limited in the lifting slot 21. A fixed block 231 is fixed or welded to the lifting block 213 on one side close to the notch of the lifting slot 21. The size of the fixed block 231 matches the size of the notch of the lifting slot 21. The fixed block 231 is horizontally arranged. A lifting plate 23 is fixed to the end of the fixed block 231 away from the lifting block 213. The surface of the lifting plate 23 is horizontally arranged. The lifting plate 23 is fixed to the lifting block 213 through the fixed block 231. Thus, the driving motor 24 rotates forward and reversely, and drives the lifting plate 23 to rise and fall through the lifting wire 211. Before climbing the power tower, the technicians place the testing equipment on the lifting plate 23 to achieve the function of auxiliary lifting.

[0035] Reference Figure 2 and Figure 3 Furthermore, in order to stabilize the lifting plate 23 and keep it level during the sliding process, a support block 232 is provided on the bottom side of the lifting plate 23. The main part of the support block 232 is inclined, one end of which is connected to the bottom side of the lifting plate 23, and the other end is fixed to the bottom end of the lifting block 213 to form a triangular support structure; the top end of the support block 232 is connected to the surface of the lifting plate 23 by a hinge, and the axial direction of the hinge axis is parallel to the surface of the lifting plate 23. The lifting plate 23 is given a rotation margin by a hinge. In actual application, the structure of the tower leg 2 is not completely oblique and straight. When the lifting block 213 inside the lifting slot 21 slides, it is difficult for the lifting plate 23 to maintain a completely horizontal state. Therefore, a hinge structure needs to be provided to accommodate a slight rotation of the lifting plate 23.

[0036] Reference Figure 1 and Figure 3 The auxiliary groove 22 is a T-shaped groove, and an auxiliary block 221 is slidably connected in the auxiliary groove 22. The auxiliary block 221 is an I-shaped block. One end of the auxiliary block 221 is slidably connected in the auxiliary groove 22, and one end of the I-shaped block is limited in the auxiliary groove 22 by the narrow structure of the T-shaped groove. The end of the auxiliary block 221 away from the auxiliary groove 22 is a free end, which is used to connect the bottom end or one side edge of the lifting plate 23. There is no unique connection method, which is not shown in the figure of this embodiment. A soft connection is preferably used, specifically a metal chain, and the auxiliary block 221 and the lifting plate 23 are connected by the metal chain. The implementation principle of an auxiliary lifting device for power tower maintenance in an embodiment of the present application is as follows: before the maintenance work begins, the technician connects the rotating shaft of the drive motor 24 to the coupling disk 25, places it on a metal plate, and connects it to the fixed pulley 26 through the coupling disk 25. The drive motor 24 drives the fixed pulley 26 to rotate, driving the lifting block 213 to rise.

[0037] The technician operates the electronic control component of the drive motor 24, sets the preset height for the lifting platform 23 to rise, places the heavy objects required for maintaining the cables and wires on the lifting platform 23, and the lifting platform 23 rises to the preset height while the technician is climbing.

[0038] During the lifting process of the lifting plate 23, the hinged structure between the lifting plate 23 and the support plate provides the lifting plate 23 with a rotation margin to accommodate the angle change of the lifting plate 23. At the same time, the auxiliary block 221 improves the stability of the lifting plate 23 through a flexible connection in the auxiliary slot 22. On the other hand, the embodiment of the present application discloses a control system applied to the above-mentioned auxiliary lifting device for power tower maintenance, referring to Figure 6 A control system for an auxiliary lifting device for power tower maintenance includes a central processing module 4, a test module 7, a front-end control module 8, an input module 9, a wireless module 5, and a display module 6.

[0039] The central processing module 4 is a portable engineering computer, which stores instruction files and data calculation files internally, and can meet the data calculation and instruction sending needs of technicians. The input module 9 provides an instruction input channel, which is integrated with the engineering computer of the central processing module 4, and can also be separated from the engineering computer separately; the technician inputs the corresponding instruction through the input module 9, and the central processing module 4 receives the input instruction signal, runs the corresponding instruction file, and generates the control instruction; the front-end control module 8 is mainly composed of the electric control circuit of the drive motor 24, which is used to receive and execute the control instruction of the central control module, so that the drive motor 24 runs according to the needs of the technician.

[0040] The display module 6 displays the calculation results and instruction progress of the central processing module 4 , so that the technicians can obtain the operating status of the drive motor 24 in real time.

[0041] Reference Figure 1 The wireless module 5 connects the display module 6 and the central processing module 4, and the input module 9 and the central processing module 4. After the technician climbs to the preset height, the command signal is remotely input through the input module 9, and the wireless module 5 transmits the command signal to the central processing module 4; the display module 6 receives the command process and calculation results of the central processing module 4 at a long distance through the wireless transmission of the wireless module 5, so that the technician who is doing maintenance work at the top of the power tower can remotely obtain the operation status of the drive motor 24; since the wireless module 5 in this embodiment does not need to perform ultra-long-distance transmission, the wireless module 5 can use a Zigbee module or a Bluetooth module.

[0042] Furthermore, the display module 6 and the input module can be a mobile device integrated with the wireless module 5 .

[0043] Reference Figure 1The test module 7 is used to test the load of the drive motor 24. After the technician connects the drive motor 24 to the fixed pulley 26 through the coupling disk 25, the torque load of the drive motor 24 is tested. Specifically, a torque sensor can be used. The test module 7 is connected to the central control module, receives the control instruction of the central control module, starts the data collection process, and sends the collected data to the central control module. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
