[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] In one embodiment, see Figure 1 and Figure 2, provides a transmission line live working lifting platform, including a platform main frame 11, a platform top frame 12 arranged on the platform main frame 11, and a hanger 13 installed on the platform top frame 12. The platform top frame 12 is also provided with a wire passing device 14 on the inner edge of the frame body, and the wire passing devices 14 are respectively arranged on both sides of the platform top frame 12; the frame wall of the platform main frame 11 is provided with a side bracket 15, and the side bracket 15 is slidably installed with an adjustment support 16, and the adjustment support 16 is provided with two and is respectively arranged at both ends of the side bracket 15, and the adjustment support 16 is installed with a routing rack 1 7. A wire routing frame 18 is installed on the wire routing rack 17; the wire passing device 14 includes a wire passing fixing seat 21 fixed on the platform top frame 12 and a wire routing sliding seat 22 installed on the wire passing fixing seat 21, and the wire routing sliding seat 22 is respectively installed with an outer wing bracket 23 and a swing arm 25, the outer wing bracket 23 is rotatably arranged on the outer end of the wire routing sliding seat 22 and is installed with a wire passing soft roller 24; the swing arm 25 is provided with a wire passing grabbing frame 26 and a wire passing hook 27 installed on the rod end of the wire passing grabbing frame 26, and the wire passing grabbing frame 26 is foldably installed on the swing arm 25.

[0033] The platform main frame 11 is a supporting structure of the entire platform, capable of withstanding various loads that may be generated during live working. The platform top frame 12 is installed on the platform main frame 11. The hanger 13 is made of high-strength materials, such as steel or alloy, and has a certain shape and size to meet the suspension requirements of different tools and equipment. It is connected and fixed to the platform top frame 12 of the lifting platform through fasteners such as bolts and nuts. This embodiment is based on the existing live working lifting platform and is committed to optimizing the wire passing and routing implementation structure of the lifting platform.

[0034] Two wire-passing devices 14 are provided at the inner edge of the platform top frame 12, and they are located on both sides of the platform top frame 12. The wire-passing devices 14 are designed to ensure that the wires can pass through the platform safely and orderly during live working. Each wire-passing device 14 includes a wire-passing fixing seat 21 fixed on the platform top frame 12, and a wire-routing push seat 22 installed on the wire-passing fixing seat 21. The wire-routing push seat 22 can move within a certain range along the wire-passing fixing seat 21 to meet the management requirements of different wires.

[0035] On the wire routing seat 22, we installed an outer wing bracket 23 and a swing arm 25. The outer wing bracket 23 is rotatably arranged at the outer end of the wire routing seat 22, and is installed with a wire passing soft roller 24. The function of the wire passing soft roller 24 is to reduce the friction and wear of the wire when passing through, ensuring the safe transmission of the wire. The swing arm 25 is provided with a wire passing grabbing frame 26 and a wire passing hook 27. The wire passing grabbing frame 26 is foldably installed on the swing arm 25, which can easily grab and fix the wire. The wire passing hook 27 is used to further fix the wire to prevent it from slipping or loosening during operation.

[0036] Side brackets 15 and adjustment brackets 16 are also provided on the frame wall of the platform main frame 11. The adjustment brackets 16 are provided to further increase the stability and flexibility of the platform. A wiring rack 17 is installed on each adjustment bracket 16, and a wiring rack 18 is installed on the wiring rack 17. The wiring rack 18 is designed to be installed or supported on the wires of the next layer, and can arrange and support the wires in an orderly manner to prevent the wires from being messy, crossed or overlapped, thereby reducing the risk of short circuit, wear or damage to the wires.

[0037] The present invention enables the wires to pass through the platform safely and orderly through reasonable design, reducing the time that operators need to handle wires during live working, thereby improving working efficiency. The wire-passing device 14 can effectively adjust the position of the hook and fixed cable during operation, so that the cable can be quickly hooked during operation, reducing the manual operation of operators and reducing the operating risk. The design of components such as the routing rack 17 effectively reduces the friction and wear of the wires during live working, reduces the risk of wire breakage or short circuit, and thus enhances the safety of the operation. The arrangement of components such as the adjustment support 16 and the swing arm 25 allows the platform to be flexibly adjusted according to different operating requirements, improving the applicability and flexibility of the platform.

[0038] In one embodiment, see Figure 1 , Figure 3 and Figure 4 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the side wing bracket 15 and the adjustment support 16 is designed as follows:

[0039] The side wing bracket 15 includes an end seat 31, a sliding rod 32 and a bidirectional threaded screw 33. The end seat 31 is arranged at both ends of the side wing bracket 15 and fixedly installed on the frame of the platform main frame 11. The sliding rod 32 and the bidirectional threaded screw 33 are both supported between the end seats 31 at both ends; the adjustment support 16 includes an adjustment frame plate 35, an adjustment support 36 fixed on the adjustment frame plate 35, and a wiring rack fixing plate 37 installed on the adjustment support 36; the adjustment support 36 is provided with a sliding sleeve and a screw sleeve, and the adjustment support 36 is respectively sleeved on the sliding rod 32 and the bidirectional threaded screw 33 through the sliding sleeve and the screw sleeve, and the wiring rack 17 is fixedly installed on the wiring rack fixing plate 37.

[0040] The power input end of the bidirectional threaded screw 33 is externally connected to a screw motor 34, which can be realized by rotating the bidirectional threaded screw 33, so that the two adjustment supports 16 can move synchronously in the horizontal direction, and the slide bar 32 plays an auxiliary limiting effect to adjust the position of the wiring rack 17. At the same time, the solid support structure of the slide bar 32 and the bidirectional threaded screw 33, as well as the reinforced design of the adjustment support 16, ensure the stability and safety of the lifting platform during live operation.

[0041] Regarding the specific implementation structure of the wiring rack 17 and the wiring rack 18, this embodiment is also designed as follows:

[0042] The wiring rack 17 includes a wiring rack base 41, a swing bracket 42 installed on the wiring rack base 41, and a fixed frame bolt 43 arranged at the frame end of the swing bracket 42. The wiring rack base 41 is fixed on the wiring rack fixed plate 37, and the swing bracket 42 is installed on the frame plate of the wiring rack base 41 through a swing shaft; the wiring rack 18 includes a roller support plate 44 installed on the fixed frame bolt 43 and a plurality of plate support shafts 45 arranged on the roller support plate 44, and a wheel roller frame 46 is installed on the plate support shaft 45, and a wiring roller 47 is installed on the wheel roller frame 46. The wiring rack base 41 is also provided with a lower edge frame box 51, and the lower edge frame box 51 is internally installed with an inner box support plate 54, and an inner push seat 52 and an inner push cylinder 53 installed on the inner push seat 52 are arranged on the inner box support plate 54, and the telescopic end of the inner push cylinder 53 is connected to the swing bracket 42.

[0043] The wiring rack base 41 is used to support the swing bracket 42 and other components. The wiring rack base 41 is fixedly mounted on the wiring rack fixed plate 37 by bolts or other connectors to ensure the stability of the overall structure. The swing bracket 42 is mounted on the frame plate of the wiring rack base 41 through a swing shaft and can swing around the swing shaft at a certain angle. The design of the swing bracket 42 allows the wire to adjust the angle as needed to adapt to different working environments. The fixed frame bolt 43 is set at the frame end of the swing bracket 42 and is used to fix and install the roller support plate 44, which provides support for the plate support shaft 45. The wiring wheel rollers 47 are all installed on the wheel roller frame 46 to support and guide the wires. The surface of the wiring wheel rollers 47 is usually made of wear-resistant material to reduce the wear of the wires during the rolling process. The number and arrangement of the wire rollers can be adjusted as needed to adapt to wires of different diameters and quantities. The inner push cylinder 53 is a hydraulic or pneumatic cylinder, and its telescopic end is connected to the swing bracket 42. By controlling the extension and retraction of the inner push cylinder 53, the swing bracket 42 can be driven to swing, thereby adjusting the angle and position of the wire.

[0044] This embodiment has high flexibility. Through the design of the swing bracket 42 and the inner push cylinder 53, the angle and position of the wire can be adjusted as needed, thereby improving the efficiency of wire management during live working. The wiring rack 17 and the wiring rack 18 can arrange and support the wires in an orderly manner, reduce the risk of wire entanglement and falling off, and reduce the probability of safety accidents such as electric shock and short circuit.

[0045] In one embodiment, see Figure 2 and Figure 5 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the wire-passing fixing seat 21 and the wire-routing pushing seat 22 is designed as follows:

[0046] The wire-passing fixed seat 21 includes a hanging bracket 62, a pushing frame 63 installed on the hanging bracket 62, and a pusher 64 arranged on the pushing frame 63. The hanging bracket 62 is fixed to the frame plate of the platform top frame 12 through a hanging base plate 61; the main body of the wiring pushing seat 22 is a wiring support frame 67, and the pushing end of the pusher 64 is provided with a pushing mechanism 65. One end of the wiring support frame 67 is fixedly installed with the pushing mechanism 65 through a pushing bracket 66, and the other end of the wiring support frame 67 is installed with a fine-tuning head 68. The outer wing bracket 23 is installed on the fine-tuning head 68, and the swing arm 25 is installed on the wiring support frame 67.

[0047] The hoisting bracket 62 serves as the basic support structure of the entire wire-passing fixed seat 21. The bracket is fixed to the frame plate of the platform top frame 12 through the hoisting base plate 61 to ensure the stability of the entire structure. The pusher 64 is driven by electric or hydraulic means. The pushing end of the pusher 64 is equipped with a pushing mechanism 65, which is a precision-machined component that can ensure that the thrust is accurately and smoothly transmitted to the operated component. The main body of the wiring push seat 22 is a wiring support frame 67. One end of the wiring support frame 67 is fixedly installed with the pushing mechanism 65 through the pushing bracket 66. In this way, when the pusher 64 is started, the wiring support frame 67 can be driven to move in a specific direction through the pushing mechanism 65 and the pushing bracket 66. The other end of the wiring support frame 67 is equipped with a fine-tuning head 68, which further enhances the control ability of the working area and allows the operator to adjust the position of the transmission line in a larger range.

[0048] See also Figure 5 , Figure 6 and Figure 7 , regarding the installation implementation of the swing arm 25 and the outer wing bracket 23, this embodiment is designed as follows:

[0049] The fine-tuning head 68 includes a head frame 71, a fine-tuning rotator 72 arranged on the head frame 71, and a fine-tuning shaft 73 installed on the driving end of the fine-tuning rotator 72. The fine-tuning head 68 is a rotating implementation structure. The driving end of the fine-tuning rotator 72 is connected to the fine-tuning shaft 73, which is a precision-machined shaft part that can transmit the torque and rotation angle generated by the fine-tuning rotator 72. The frame plate of the outer wing bracket 23 is installed on the fine-tuning shaft 73, and a soft wire roller 24 is installed on the frame plate of the outer wing bracket 23. The soft wire roller 24 is made of soft and wear-resistant material, such as rubber, polyurethane or other synthetic materials, and is designed to be cylindrical or conical to accommodate cables of different diameters. When the live transmission line operation lifting platform is operating, the outer wing bracket 23 is designed to be rotatable, allowing it to adjust its angle as needed during operation to adapt to different transmission line positions. The soft wire roller 24 supports the cable to ensure that the cable will not be subjected to excessive friction and wear during movement. At the same time, the easy-to-disassemble design of the soft wire roller 24 allows staff to easily inspect and replace it.

[0050] The main body of the swing arm 25 is an arm frame 82, one end of the arm frame 82 is fixed to the wiring support frame 67 through an arm end fixing sleeve 81, and the other end of the arm end fixing sleeve 81 is provided with a positioning ring 83. The wire-passing grabbing frame 26 includes a middle support shaft 84 and a swing frame 85 installed at both ends of the middle support shaft 84, the middle support shaft 84 is installed in the positioning ring 83, and the wire-passing hook 27 is installed at the end of the swing frame 85. The inner frame of the arm frame 82 is provided with a movable mounting bolt 91, and a telescopic cylinder 92 is installed on the movable mounting bolt 91. The driving end of the telescopic cylinder 92 is installed with a telescopic rod 93, and the telescopic rod 93 is connected to the shaft rod of the middle support shaft 84 through a folding plate 94.

[0051] The swing arm 25 is a key component for connecting the cable support frame 67 and the cable grabbing frame 26, which realizes the flexible grabbing and moving of the cable; the main body of the swing arm 25 is an arm frame 82, and a positioning ring 83 is provided at one end of the arm frame 82 for installing and positioning the cable grabbing frame 26. The cable grabbing frame 26 includes a central support shaft 84 and swing frames 85 installed at both ends of the central support shaft 84, so that the cable grabbing frame 26 can move flexibly with the swing of the swing arm 25. The end of the swing frame 85 is installed with a cable hook 27 for grabbing and fixing the cable.

[0052] In order to realize the flexible swing of the swing arm 25, the inner frame of the arm frame 82 is provided with a movable mounting bolt 91. The movable mounting bolt 91 not only provides a mounting base for the arm frame 82, but also allows it to move within a certain range, thereby enhancing the flexibility of the swing arm 25. In addition, the telescopic rod 93 is connected to the shaft rod of the middle support shaft 84 through the folding plate 94. This connection method not only ensures that the telescopic rod 93 can stably drive the swing arm 25 to swing, but also enables the swing arm 25 to remain stable and precise during the swinging process. The swing arm 25 realizes flexible grasping and movement of cables through its precise structure and flexible connection method, so that the lifting platform can be more widely used in various cable operation environments.

[0053] See also Figure 8 The present embodiment also discloses an implementation structure of a wire-passing hook 27, wherein a mounting ring 101 is installed at the end of the swing frame 85, and the main body of the wire-passing hook 27 is a hook bolt 103, and the mounting end of the hook bolt 103 is installed on the mounting ring 101 by folding a hanging bolt 102, and the hook bolt 103 is designed to be bent inwardly and has a threading interval 106 formed therein, and an active buckle 105 is installed on the inwardly bent portion of the hook bolt 103 through an elastic reset bolt 104, and the active buckle 105 is used to close the threading interval 106.

[0054] The end of the swing frame 85 is equipped with a mounting ring 101, and the mounting end of the bolt 103 is cleverly mounted on the mounting ring 101 by folding the hanging bolt 102, allowing the bolt 103 to be folded and adjusted within a certain range. The bolt 103 is designed to be bent inward and has a threading section 106. This design allows the cable to quickly pass through the bolt 103 and be firmly grasped. A notch is provided on the side edge of the bolt 103, and the movable buckle 105 is opened and closed at the notch position, which can be automatically reset and closed by the elastic reset bolt 104 to firmly grasp the cable.

[0055] This design of the present embodiment greatly shortens the operation time and improves the work efficiency. The staff can fix the cable to the designated position more quickly, reducing unnecessary waiting and repeated operations, and also reducing the potential safety hazards caused by misoperation. In addition, its positioning design reduces the movement and shaking of the cable during the operation, reducing the risk caused by the cable falling off or sliding.
