Description

Technical Field

[0001] This application relates to the field of cable tray technology, and in particular to a power communication transmission device. Background Technology

[0002] In power communication systems, efficient and safe cable laying and management are key to ensuring stable signal transmission. Traditional cable tray structures, due to their complex installation, poor flexibility, and insufficient heat dissipation protection, are no longer able to meet the development needs of modern power communication.

[0003] When faced with complex wiring layouts requiring bends and turns, conventional conduits cannot flexibly change direction in existing transmission equipment. Custom-designed conduits with special angles are often required for connections, increasing procurement costs and delivery time, and making on-site installation and commissioning cumbersome. Furthermore, internal cables are typically bundled together for centralized fixation, resulting in limited space for heat dissipation. This makes it difficult for heat generated during operation to dissipate, easily causing localized overheating, softening or even melting the cable insulation, thus reducing electrical performance and shortening lifespan. Moreover, if the internal wiring harnesses of the transmission equipment catch fire, the relatively enclosed structure of the cable trays prevents external fire extinguishing agents from reaching the fire source quickly and effectively, and the internal oxygen cannot be expelled in time, potentially leading to the spread of the fire and causing greater damage.

[0004] In cold and humid regions, traditional cable trays are ill-suited to withstand the intrusion of moist air. When this air enters the tray, it encounters the high temperatures generated by the cables during operation, causing the moisture to evaporate rapidly and form steam and condensation. This steam and condensation adhere to the surface of the cables, accelerating oxidation and corrosion and shortening their lifespan. Furthermore, the moisture may penetrate the insulation layer, reducing insulation performance and potentially causing serious safety incidents such as leakage and short circuits, posing a significant threat to the stable operation of power communication systems.

[0005] Furthermore, when workers inspect the transmission device, toolboxes typically need to be carried from the ground to a height by others, increasing manpower costs and posing a safety hazard of tools falling. During maintenance, power tools require long-distance wiring to obtain power if there are no nearby outlets, which is cumbersome and may pose a risk of electric shock due to messy wiring. Additionally, existing transmission devices are often installed using bolted connections between hoisting columns and cable trays. These columns are usually fixed to rooftops or other locations using expansion bolts, and over time, the weight of the cable trays, vibrations, and environmental factors can cause the fixing points to loosen or even detach, seriously threatening equipment and personnel safety. Therefore, this application designs a power communication transmission device to solve the above problems. Summary of the Invention

[0019] A sliding groove is provided on the mounting plate between the smoke temperature alarm sensor and the high-pressure nozzle.

[0020] Furthermore, the bottom surface of the cable tray is symmetrically equipped with two guide rails, and a storage drawer is slidably installed between the two guide rails. Two spring wires are symmetrically arranged in the middle of the bottom surface of the storage drawer. One end of the spring wire is equipped with an aviation plug. The two ends of the guide rail are equipped with corresponding aviation plug connectors. Two collection boxes are symmetrically fixed on both sides of the spring wires in the storage drawer. Multiple wireless charging pads are installed in the middle of the collection boxes. Power sockets are installed between two adjacent wireless charging pads. Multiple dividers are equidistantly arranged inside the collection boxes. A toolbox slot is opened on one side of the storage drawer located in the collection box.

[0021] Furthermore, a motor base is welded to the upper part of one side of the hoisting column, and a second motor is installed on the motor base. A take-up box is fixedly connected to one end of the second motor. A take-up roller, coaxially fixed to the output shaft of the second motor, is rotatably installed inside the take-up box. A detection plate is fixedly connected to one end of the take-up roller. Two triangular grooves are symmetrically opened on the detection plate. Reflective patches are attached to the triangular grooves. A diffuse reflection photoelectric sensor is installed at an angle on the upper part of the inner wall of the take-up box. A safety rope is wound around the take-up roller, and the safety rope spirally connects the take-up rollers in multiple take-up boxes in pairs.

[0022] The advantages of this application over the prior art are as follows:

[0023] 1) Through the cooperation of multiple hinged rectangular frames, spring pins, and first plug-in posts, the operator pulls the connecting plate to drive the pull plate to retract the spring pins. After inserting the first plug-in post into the slotted cable tray socket, the connecting plate is released, and the spring pin pops out and locks in place. This facilitates quick connection between slotted cable trays and allows for free adjustment of angles, improving installation flexibility and convenience. This enables the transmission device to freely bend in complex lines.

[0024] 2) The heat dissipation holes of the pressure plate and the cable tray form an air circulation channel, allowing the cable heat to dissipate through the heat dissipation holes, which facilitates faster heat dissipation and improves heat dissipation efficiency. This reduces cable temperature and protects the insulation layer, solving the problem of poor heat dissipation and reduced performance caused by cable bundling, and extending cable life. When the smoke temperature alarm sensor is triggered, the observation camera is activated to confirm the fire. If there is an open flame or smoke, the electric motor is activated, which drives the internal threaded cylinder to rotate, causing the second threaded rod to move forward in a straight line. This pushes the vertical plate and the sealing plate on the horizontal bar to block the ventilation opening. At the same time, the electronic valve opens, allowing the heptafluoropropane in the fire extinguishing gas canister to be sprayed out from the high-pressure nozzle through the high-pressure metal hose. This facilitates the blocking of oxygen and rapid extinguishing of the fire, improving the timeliness and effectiveness of fire extinguishing, and thus enabling the control of the spread of fire. The smoke temperature alarm sensor detects the humidity inside the cable tray in real time. When the humidity exceeds the set threshold, the semiconductor cooling chip is activated. Its cold end works with the humid air inside the cable tray, facilitating the condensation of the humid air into water droplets, improving the efficiency of condensation and dehumidification, and thus enabling the dehumidification function inside the transmission device.

[0025] 3) The combination of diversion hood, water inlet pipe, cable tray, water guide plate and drain pipe facilitates the orderly discharge of condensate to the outside of the trough-type cable tray, improving the smoothness of drainage and thus preventing the accumulation of condensate. At the same time, the inner wall of the trough-type cable tray and the cable tray are coated with a nano hydrophobic coating, which, in conjunction with the condensate discharge process, reduces the residue of condensate on the inner wall of the trough-type cable tray, improves the moisture-proof performance of the transmission device, and thus avoids problems such as cable short circuits and metal component corrosion caused by moisture.

[0026] 4) By cooperating with the sealing block and the second rectangular through groove, the sealing block can easily block the second rectangular through groove when the cable is not laid, which improves the sealing performance of the inside of the cable tray and prevents foreign objects from entering the inside of the cable tray. Furthermore, by cooperating with the weight of the cable, the spring telescopic rod and the sealing block, the sealing block can easily release the seal after the cable is laid. At the same time, the arc-shaped support plate supports the cable, which improves the flow efficiency of condensate water. This enables condensate water to pass smoothly through the second rectangular through groove into the cable tray and avoids water accumulation on the cable.

[0027] 5) The combination of collection boxes and dividers in the storage drawer facilitates the classification and storage of maintenance tools, eliminating the need for others to deliver them and improving the convenience of tool retrieval. This allows workers to carry tools independently for maintenance. Furthermore, the wireless charging base and power socket enable power tools to be charged or plugged in directly without the need for remote wiring, improving the convenience and safety of power supply and ensuring efficient power supply to power tools during maintenance.

[0028] 6) Through the cooperation of the safety rope on the hoisting column, the take-up roller, and the diffuse reflection photoelectric sensor, the diffuse reflection photoelectric sensor has a built-in microcontroller. When the hoisting column becomes loose, the safety rope pulls the take-up roller to rotate, which in turn drives the detection disc to rotate. Each time the reflective patch on the disc passes the diffuse reflection photoelectric sensor, the sensor emits a pulse signal. The microcontroller counts the pulse signals, and when the count reaches 2, it determines that the take-up roller has rotated one revolution. When the continuous rotation is greater than or equal to 4 revolutions, the microcontroller automatically sends an electrical signal to start the second motor to take in the wire. This facilitates the timely detection of potential loosening and actively tightens the safety rope, improving installation stability and preventing the hoisting column from falling. At the same time, the second motor... The motor with built-in torque detection monitors the output torque in real time during the cable winding process. When the torque reaches a preset threshold, it indicates that the safety rope is taut, and the second motor immediately stops winding. This allows for precise control of the safety rope tension, improving the reliability of the safety rope fixation. This, in turn, prevents the lifting column from loosening and falling off, and avoids damage from excessive tension on the safety rope. Ultimately, it solves the problems of insufficient heat dissipation and protection of traditional transmission cable trays, damage to cables and transmission cable tray components caused by moisture intrusion of humid air in cold and humid regions, the need for others to deliver tools during maintenance, inconvenient power supply for power tools, and the ease with which lifting columns can fall off without protection. This improves the installation efficiency, cable operation stability, and safety of power communication transmission devices. Attached Figure Description

The multiple hinged rectangular frames 10 can be flexibly adjusted in angle. By pulling the pull plate 15 and the connecting plate 16, the extension and retraction of the spring pin 14 can be controlled, enabling quick connection and disassembly with the trough-type cable tray 1.

By pulling the pull ring 29, the rod 26 and the disc 23 are moved. The lifting and fixing of the pressure plate 21 is realized by the cooperation of the protrusion with the guide groove, ring groove 25 and snap-fit ​​groove inside the guide cylinder 24. This facilitates the clamping or loosening of the cable, ensuring that the cable is laid neatly and stably, and avoiding the cable shaking from affecting signal transmission.

The output shaft of the electric motor 37 is coaxially fixed to an internally threaded cylinder 38. A second threaded rod 39 is screwed into the internally threaded cylinder 38. A vertical plate 40 is rotatably mounted on one end of the second threaded rod 39. Two horizontal bars 41 are symmetrically mounted on one side of the vertical plate 40. Multiple sealing plates 42 are equidistantly mounted on the bottom surface of the two horizontal bars 41. The electric motor 37 drives the internally threaded cylinder 38 to rotate, which in turn moves the second threaded rod 39, thereby moving the vertical plate 40, the horizontal bars 41, and the sealing plates 42. The ventilation opening 9 can be opened or closed as needed. While ensuring ventilation and heat dissipation, the ventilation opening 9 can be closed in time when encountering severe weather or when dust prevention is required, protecting the cables and equipment inside the cable tray 1 and improving the environmental adaptability of the transmission device. The vent 9 has a first rectangular through groove corresponding to the sealing plate 42, and multiple sealing plates 42 are located on one side of the first rectangular through groove; the inside of the trough-type cable tray 1 has a support platform 43 located on the bottom surface of the internal threaded cylinder 38 and the electric motor 37; the first rectangular through groove cooperates with the sealing plate 42 to ensure that the sealing plate 42 can move accurately and close the vent 9; the support platform 43 can support the internal threaded cylinder 38 and the electric motor 37, improve the stability of the sealing component, and ensure its long-term reliable operation.

[0057] In this embodiment, the electric motor 37 is model ZYT50S-RA, which has high torque and stable operation; the support platform 43 is made of welded steel plate, which has strong load-bearing capacity.

A cooling fan 45 is installed on the top surface of the circulating pump 44. Rectangular slots are opened on both sides of the mounting plate 6 at the circulating pump 44. Heat dissipation fins 46 are installed in the rectangular slots. A semiconductor cooling chip 47 is fixed to the bottom surface of the heat dissipation fins 46 and extends out of the bottom surface of the mounting plate 6. A diversion shroud 48 is installed on the bottom surface of the mounting plate 6 at the location of the semiconductor cooling chip 47. The bottom surface of the diversion shroud 48 is inclined. A water inlet pipe 49 is connected to the lower end of the bottom surface of the diversion shroud 48, and an air outlet 50 is opened on the higher end of the bottom surface of the diversion shroud 48. A sealing rubber gasket is fixed to the contact surface between the wire clamping plate 21 and the wiring plate 7. A circulating copper pipe 57 is arranged in a serpentine pattern inside the heat dissipation fins 46. The two ends of the circulating copper pipe 57 extend from the two ends of the top surface of the heat dissipation fins 46 and are connected to the circulating pump 44. This structure, through the cooperation of the circulating pump 44, cooling fan 45, heat dissipation fins 46, semiconductor cooling chip 47 and distribution shroud 48, facilitates cooling and dehumidification of the inside of the trough-type cable tray 1, improving the transmission device's ability to cope with humid environments; the sealing rubber gasket enhances the internal sealing performance, thereby enabling the transmission device to achieve the functions of internal dehumidification and sealing protection.

[0059] In this embodiment, the circulating pump 44 is model CHL2-20, the cooling fan 45 is model DF-12025, and the semiconductor cooling chip 47 is model TEC1-12706; the heat dissipation fins 46 are made of aluminum alloy, which has good thermal conductivity; and the shroud 48 is made of PVC plastic, which is lightweight and water-resistant.

[0060] like Figure 1 , 2 As shown in Figures 10 and 11, the cable tray 7 is hollow inside. Water inlet grooves are provided on both sides of the top surface of the cable tray 7. One end of the water inlet pipe 49 extends into the water inlet groove. Both the cable tray 1 and the cable tray 7 are coated with a nano-hydrophobic coating. The gap between the water inlet pipe 49 and the water inlet groove, in conjunction with the nano-hydrophobic coating, provides a drainage channel for condensate on the inner wall of the cable tray 1, ensuring dehumidification. A water guide plate 56 is provided on the bottom surface of the cable tray 7. Two drain pipes 51 are symmetrically connected on both sides of the inclined end of the water guide plate 56. One end of the drain pipe 51 extends out of the outer wall of the cable tray 1. Multiple second rectangular grooves are equidistantly provided on the cable tray 7. An arc-shaped support plate 52 is movably installed within the second rectangular groove. A connecting block 53 is fixedly connected to the bottom surface of the support plate 52, and a sealing block 54 is fixedly connected to the bottom end of the connecting block 53. The telescopic ends of spring telescopic rods 55 are fixedly connected to both ends of the bottom surface of the sealing block 54. The fixed ends of the spring telescopic rods 55 pass through the water guide plate 56 and are fixed to the inner bottom surface of the cable laying plate 7. The shape of the sealing block 54 corresponds to the second rectangular through groove. This structure, through the cooperation of the sealing block 54, the spring telescopic rod 55 and the arc-shaped support plate 52, prevents foreign objects from entering when the cable is not laid. After the cable is laid, it facilitates the entry of condensate into the cable laying plate 7 for drainage. At the same time, the arc-shaped support plate 52 supports the cable to prevent water accumulation, which improves the transmission device's ability to handle condensate and protect the cable. Thus, it can realize the functions of preventing foreign objects and efficient drainage inside the transmission device.

[0061] In this embodiment, the cable laying plate 7 is made of engineering plastic material, which has the characteristics of good insulation and strong corrosion resistance. The nano-hydrophobic coating of the cable laying plate 7 reduces the adhesion of condensate water, and together with the drainage structure, ensures that the inside of the transmission device is dry and ensures the safe operation of the cable.

[0062] like Figure 2 , 12As shown, a sliding groove is provided on the mounting plate 6 between the smoke temperature alarm sensor 31 and the high-pressure nozzle 36. A lead screw 58 is rotatably mounted in the sliding groove, and a sliding sleeve is sleeved on the lead screw 58. A thermal imager 59 is fixed to the bottom surface of the sliding sleeve. A first motor 60 installed in one end of the mounting plate 6 is coaxially fixed to one end of the lead screw 58. The thermal imager 59 is moved back and forth on the bottom surface of the mounting plate 6 by the lead screw 58 to achieve repeated detection, which can collect the temperature distribution image of the cable surface in real time. Through image processing algorithms, the temperature data is converted into a visualized thermal imaging map. Once an abnormal increase in local temperature of the cable is detected, such as exceeding the set threshold, the system immediately issues an alarm and transmits the abnormal location and thermal imaging image to the monitoring terminal through the wireless communication module.

[0063] In this embodiment, the thermal imager 59 is model HM-TJ61-3AF.

[0064] like Figure 13 , 14 As shown, the bottom surface of the cable tray 1 is symmetrically equipped with two guide rails 61, and a storage drawer 62 is slidably installed between the two guide rails 61. Two spring wires 63 are symmetrically arranged in the middle of the bottom surface of the storage drawer 62. One end of the spring wire 63 is equipped with an aviation plug 64. The two ends of the guide rails 61 are equipped with corresponding docking connectors 65 for the aviation plugs 64. Dust covers are hinged on the docking connectors 65. Two collection boxes are symmetrically fixed on both sides of the spring wires 63 in the storage drawer 62. Two wireless charging bases 66 are installed in the middle of the collection boxes. A power socket 67 is installed between the two wireless charging bases 66. Multiple partitions 68 are equidistantly arranged inside the collection boxes. A cover plate 69 is overlapped on the upper end of the collection box at the partitions 68. Multiple through holes of progressively larger size are equidistantly opened on the top surface of the cover plate 69 between the gaps of the multiple partitions 68. Positive magnetic blocks 78 are fixed to the opposite surfaces at both ends of the two guide rails 61. Sliding blocks 79 are provided on the middle of both sides of the storage drawer 62 and are slidably mounted on the guide rails 61. Negative magnetic blocks 80 corresponding to the positive magnetic blocks 78 are fixed to both ends of the sliding blocks 79. A toolbox slot is provided on one side of the storage drawer 62 located in the collection box. The storage drawer 62 is convenient for storing maintenance tools. The wireless charging base 66 and the power socket 67 solve the power supply problem for power tools. The magnetic structure ensures the stability of the drawer, improves the convenience and safety of maintenance, and reduces the cost of manual coordination.

[0065] In this embodiment, the storage drawer 62 is made of 304 stainless steel; the wireless charging stand 66 has an output power of 15W and supports the Qi wireless charging protocol; the positive magnetic block 78 and the negative magnetic block 80 are both neodymium iron boron magnets.

[0066] like Figure 1 , 9As shown, a motor base 70 is welded to the upper part of one side of the hoisting column 4. A second motor 71 is installed on the motor base 70. A take-up box 72 is fixedly connected to one end of the second motor 71. A take-up roller 73, which is coaxially fixed to the output shaft of the second motor 71, is rotatably installed inside the take-up box 72. A detection plate 74 is fixedly connected to one end of the take-up roller 73. Two triangular grooves are symmetrically opened on the detection plate 74. A reflective patch 75 is attached to the triangular groove. A diffuse reflection photoelectric sensor 76 is installed at an angle on the upper part of the inner wall of the take-up box 72. A safety rope 77 is wound around the take-up roller 73. The safety rope 77 connects the take-up rollers 73 in the multiple take-up boxes 72 in a spiral winding manner.

[0067] In this embodiment, the second motor 71 is a Limaisheng TSM57, which adopts FOC field-oriented control technology and SVPWM space vector modulation technology. Through these control technologies, combined with its built-in encoder and other components, and with the corresponding control algorithm, the shaft torque can be monitored and controlled, achieving high-precision, high-torque operation. It also supports the CANopen / RS485 bus communication protocol, which can transmit torque-related data through the bus. The diffuse reflection photoelectric sensor 76 is model E3Z-D61, with a detection distance of 5-30cm. The safety rope 77 is made of Kevlar, with a diameter of 5mm and a breaking strength ≥5000N. By using the reflective patch 75 and the diffuse reflection photoelectric sensor 76 to monitor the loosening of the safety rope 77, the second motor 71 automatically retracts the rope and judges the tension by torque detection, which improves the safety of the hoisting structure and prevents the risk of loosening and falling.

[0068] Working principle: In this embodiment, this application also proposes a method for using a power communication transmission device, including the following steps:

[0069] Step 1: First, attach the first sliding mounting block 3 onto the lifting column 4, ensuring that the two can slide relative to each other. Then, use bolts to fasten the triangular bracket 2 to the first sliding mounting block 3. After that, fix the trough-type cable tray 1 to the triangular bracket 2 by welding or high-strength bolts. When connecting two trough-type cable trays 1, pull the connecting plate 16 to drive the pull plate 15 to retract the spring pin 14. Insert the first insertion post 12 on the first rotating cylinder 11 into the corresponding insertion hole of the other trough-type cable tray 1. After releasing the connecting plate 16, the spring pin 14 pops out and locks in place. Use the hinged rectangular frame 10 to adjust the angle to complete the splicing. Finally, tighten the locking nuts 18 on the first threaded rods 17 at both ends of the hinge shaft to fix the angle. At the same time, apply a nano-hydrophobic coating to the inner wall of the trough-type cable tray 1 and the cable laying plate 7.

[0070] Step two: Lay the cable on the cable tray 7 inside the cable tray 1. Initially, the protrusion on the disc 23 is located in the snap-fit ​​groove of the annular groove 25, and the pressure plate 21 is in a raised state. When the cable needs to be tightened, pull the ring 29 to move the disc 23 upward, the protrusion disengages from the snap-fit ​​groove and enters the annular groove 25, rotate the ring 29 90°, move it along the annular groove 25 to the entrance of the guide groove, release the ring 29, the second spring 27 pushes the protrusion into the guide groove, and the pressure plate 21 presses down to tighten the cable. If the cable needs to be adjusted, reverse the operation to return the protrusion to the annular groove 25 and... Rotating 90° into the snap-fit ​​groove raises the pressure plate 21, releasing the pressure on the cable; as the pressure plate 21 lowers to press the cable, the heat dissipation holes 30 on the pressure plate 21 and the cable laying plate 7 form a channel for heat dissipation; during this process, when no cable is laid, the sealing block 54 blocks the second rectangular through groove under the action of the spring telescopic rod 55 to prevent foreign objects from entering; after the cable is laid, the weight of the cable presses down on the spring telescopic rod 55, the sealing block 54 releases the seal, providing a channel for condensate to enter the interior of the cable laying plate 7, while the arc-shaped support plate 52 supports the cable to prevent water accumulation;

[0071] Step 3: The smoke and temperature alarm sensor 31 monitors the smoke concentration, temperature, and humidity inside the cable tray 1 in real time. If an anomaly is detected, the observation camera 8 is immediately activated to provide comprehensive real-time monitoring of the transmission device. When the humidity exceeds a set threshold, the dehumidification mechanism is triggered, and the semiconductor cooling chip 47 is activated. Its cold end causes the humid air inside the cable tray 1 to condense into water droplets. The condensate generated by the semiconductor cooling chip 47, under the action of the nano-hydrophobic coating, quickly gathers and falls into the lower distribution hood 48. Due to the connection between the water inlet pipe 49 and the water inlet channel... There are gaps between the troughs, and the condensate generated on the inner wall of the cable tray 1 can also flow into the water inlet channel through these gaps and enter the cable tray 7. The water guide plate 56 in the cable tray 7 guides the accumulated water to be discharged to the outside of the cable tray 1 through the drain pipe 51. At the same time, according to environmental requirements, the electric motor 37 can drive the sealing component to work, drive the inner threaded cylinder 38 to rotate, and push the vertical plate 40, horizontal bar 41 and sealing plate 42 to move through the second threaded rod 39, so as to realize the opening and closing of the ventilation opening 9. In a humid and cold environment, the ventilation opening 9 can be closed in time to reduce the entry of humid air.

[0072] Step four: When the observation camera 8 confirms the presence of open flame or smoke within the cable tray 1, the electric motor 37 starts, driving the internal threaded cylinder 38 to rotate. The second threaded rod 39, screwed to the internal threaded cylinder 38, moves axially, pushing the vertical plate 40 to move the horizontal bar 41 and the sealing plate 42. This pushes the sealing plate 42 into the first rectangular slot of the ventilation opening 9, sealing the ventilation opening 9, blocking the entry of external air, and preventing the fire from spreading. Simultaneously with the closure of the ventilation opening 9, the electronic valve 34 opens, and the heptafluoropropane extinguishing gas in the fire extinguishing gas cylinder 33 is delivered to the high-pressure nozzle 36 via the high-pressure metal hose 35. The high-pressure nozzle 36 evenly sprays the extinguishing gas inside the cable tray 1 to quickly extinguish the fire and ensure the safe and stable operation of the power and communication transmission equipment. The heptafluoropropane extinguishing gas forms a mist through the high-pressure metal hose 35 and the high-pressure nozzle 36, covering the entire cavity of the transmission device. The pressure sensor in the extinguishing gas tank 33 continuously provides feedback on the spray status to ensure sufficient release of the agent. At the same time, the cable clamping assembly keeps the cable in a fixed state to prevent the cable from shifting during the fire extinguishing process. After the fire, the sealing assembly can be remotely controlled to reset, realizing the full automation of the "fire extinguishing-protection-reset" process.

[0073] Step 5: During maintenance, pull out the storage drawer 62 and extend the spring cable 63. Insert the aviation plug 64 on the spring cable 63 into the connector 65 on the guide rail 61, which is closer to the docking point, to supply power to the wireless charging pad 66 or the power socket 67. The connector 65 passes through the guide rail 61 and the cable tray 1, and is powered by a dedicated 220V cable. Place the worker's toolbox into the toolbox slot. Small parts such as screws generated during maintenance can be placed in the collection box, which is divided into compartments by multiple dividers 68 for sorting. When it is necessary to retrieve previously stored small parts, the cover 69 can be removed to retrieve the stored small parts. After the power supply is connected to the aviation plug 64 via the docking connector 65, the power tool can be powered by the wireless charging base 66 or the power socket 67. If the lifting column 4 falls off, it will cause the safety rope 77 to move, which in turn will cause the take-up roller 73 to rotate. The reflective patch 75 of the detection plate 74 rotates with it. The diffuse reflection photoelectric sensor 76 sends a pulse to the controller every time it detects a reflective signal. When the count reaches 2, it is determined that the take-up roller 73 has rotated one revolution. When it rotates continuously for ≥4 revolutions, the controller starts the second motor 71, which drives the take-up roller 73 to wind up the safety rope 77. At the same time, the torque detection function senses the tension of the safety rope 77. It stops after reaching the preset torque to ensure the safety and stability of the lifting structure.
