[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 As shown, in this embodiment, a cable laying and lifting operation device is provided. This device includes a lifting vehicle 1, which has a lifting function and can raise and lower a working platform 14 to a suitable working height. An extension platform is provided on one side of the working platform 14. The extension platform includes an extension pedal 3 rotatably connected to the working platform 14 and a power component 5 that drives the extension pedal 3 to rotate. The extension pedal 3 can expand the working area, and the power component 5 can drive the extension pedal 3 to rotate around a fixed axis close to the working platform 14. The power component 5 can be a hydraulic cylinder, an electric cylinder, or other power cylinder.

[0042] The side of the extension pedal 3 facing away from the work platform 14 is located above the cable stacking platform 8, and the extension pedal 3 is provided with several support components 4 extending toward the cable stacking platform 8. Please refer to [reference needed]. Figure 2 and Figure 3 The support component 4 is located on the side of the extension pedal 3 opposite to the work platform 14, and therefore the support component 4 is also located above the cable stacking platform 8. It should be noted that the extension pedal 3 with the support component 4 can be raised above the cable stacking platform 8 by raising the work platform 14.

[0043] Furthermore, when the work platform 14 rises or falls, the extension pedal 3 can be vertically positioned on one side of the work platform 14 via the power unit 5, without affecting the normal raising and lowering of the work platform 14; when the extension pedal 3 needs to be used, it can be unfolded via the power unit 5. Of course, when using the extension pedal 3, the work platform 14 should first be raised to an appropriate position to ensure that the extension pedal 3, after unfolding, roughly corresponds to the cable stacking platform 8.

[0044] Since the support component 4 is mounted on the extension pedal 3, when the power component 5 drives the extension pedal 3 to rotate, it can also drive the support component 4 to rotate accordingly. During the rotation, the support component 4 can abut against the cable stacking platform 8 (see 3). The support components 4 can be evenly distributed on one side of the extension pedal 3, and the support components are movable relative to the extension pedal 3 in the extension direction. Thus, when the support component 4 abuts against the cable stacking platform 8, the length of the support component 4 between the extension pedal 3 and the cable stacking platform 8 can be adjusted by the continuous rotation of the extension pedal 3 until each support component 4 abuts against the cable stacking platform 8. At this time, the support component 4 is locked relative to the extension pedal 3 in the extension direction, so that each support component 4 forms a stable support for the extension pedal 3.

[0045] Furthermore, since this application is applicable to an inclined cable stacking platform 8, when the extension platform rotates toward the cable stacking platform 8, each support component 4 cannot simultaneously abut against the cable stacking platform 8. Therefore, when some of the support components 4 abut against the cable stacking platform 8, these abutting support components 4 can move relative to the extension pedal 3, thereby ensuring that the extension pedal 3 can continue to rotate toward the cable stacking platform 8 under the action of the power component 5. When the rotation reaches the point where each support component 4 abuts against the cable stacking platform 8, the power component 5 stops rotating, and each support component 4 is locked relative to the extension pedal 3, thereby ensuring that each support component 4 has a supporting effect.

[0046] In addition, when each support component 4 abuts against the cable stacking platform 8, the corresponding extension pedal 3 is not necessarily in a horizontal state, which poses a certain safety hazard. Therefore, based on the support component 4 abutting against the cable stacking platform 8, the height of the extension platform away from the support component 4 can be adjusted by changing the height of the work platform 14, so that the work platform 14 and the extension pedal 3 are on the same horizontal plane, ensuring that the personnel work area has a stable horizontal plane.

[0047] In summary, this application, by providing a rotatable extension platform on one side of the work platform 14, increases the working area significantly beyond the original work platform 14. Simultaneously, the extension platform can conceal the gap between the work platform 14 and the cable stacking platform 8, overcoming the height difference between them and bringing the entire working area closer to a single plane, ensuring stable standing for personnel. Furthermore, one side of the extension platform is rotatably connected to the work platform 14, providing support. The other side of the extension platform abuts against the cable stacking platform 8 via several support components 4. When the cable stacking platform 8 is tilted, these support components 4 can be movably positioned relative to the extension pedal 3 in the extension direction, allowing each support component 4 to abut against the cable stacking platform 8. When each support component 4 abuts against the cable stacking platform, it locks relative to the extension pedal 3 in the extension direction, providing stable support on that side of the extension platform. Combined with the support provided by the rotatably connected side of the extension platform to the work platform 14, the extension platform provides stable support for workers, ensuring the stability of the working area.

[0048] Please refer to Figures 4 to 6 The support assembly 4 includes a steering member 41 rotatably disposed on the lower side of the extension pedal 3 and a lifting rod 42 disposed on the steering member 41. The lifting rod 42 can extend axially toward the cable stacking platform 8, and the lifting rod 42 is movably disposed relative to the extension pedal 3 in its axial direction. When the lifting rod 42 abuts against the cable stacking platform 8, the length of the lifting rod 42 between the extension pedal 3 and the cable stacking platform 8 can be adjusted.

[0049] The steering component 41 is provided with an elastic element 43 that abuts against the lower side of the extension pedal 3. The elastic element 43 can be a spring. When the lifting rod 42 is not in contact with the cable stacking platform 8, the elastic element 43 can reserve space for the steering component 41 to rotate towards the extension pedal 3. So when the lifting rod 42 abuts against the cable stacking platform 8, the lifting rod 42 will drive the steering component 41 to rotate and compress the reserved space until the steering component 41 is in contact with the lower side of the extension pedal 3, at which point the steering component 41 can no longer rotate. If the extension pedal 3 needs to continue to rotate at this time, the corresponding lifting rod 42 can be moved relative to the extension pedal 3, thereby ensuring that the extension pedal 3 is not affected by the supporting effect of the lifting rod 42.

[0050] Please refer to Figure 5 or Figure 6A sensor baffle 44 is also provided on the steering component 41, and a sensor 7 corresponding to the support component 4 is provided on the extension pedal 3. When the lifting rod 42 is not in contact with the cable stacking platform 8, the sensor baffle 44 cannot trigger the sensor 7 due to the reverse force of the elastic element 43. When the extension pedal 3 rotates toward the cable stacking platform 8 and the end of the lifting rod 42 contacts the cable stacking platform 8, it can push the steering component 41 to rotate toward the extension pedal 3. The steering component 41 compresses the elastic element 43 and drives the sensor baffle 44 to rotate a short distance. The rotated sensor baffle 44 can correspond to the sensor 7, so that the contact point or sensing end of the sensor 7 has an electrical signal, thereby triggering the sensor 7 to give a feedback signal, indicating that the corresponding lifting rod 42 has contacted the cable stacking platform 8. When one or more sensors 7 return a signal, it means that another part of the lifting rods 42 are not in contact with the cable stacking platform 8. Therefore, the extension pedal 3 needs to continue rotating toward the cable stacking platform 8 until all sensors 7 return a signal, indicating that each lifting rod 42 is in contact with the cable stacking platform 8. Then the extension platform stops rotating, and each lifting rod 42 is locked relative to the extension pedal 3 in the axial direction, thus forming a stable support extension platform.

[0051] In some embodiments, the lifting rod 42 can be threadedly engaged with the steering component 41, and the lifting rod 42 can be raised or lowered relative to the extended pedal 3 in its axial direction by means of a tool. Moreover, by utilizing the self-locking property of the threaded engagement, the lifting rod 42 can be locked relative to the extended pedal 3 in its axial direction without any operation, which has a good support effect.

[0052] In other embodiments, the lifting rod 42 can be a hydraulic lifting rod, an electric lifting rod, a pneumatic lifting rod, or a motor-driven screw lifting rod, etc., to achieve automatic control. That is, the lifting rod 42 is automatically raised and lowered relative to the extension plate 3 in its axial direction through the aforementioned power rod, and after the raising and lowering is completed, the lifting rod 42 is locked relative to the extension plate by the characteristics of the power rod itself. On this basis, the lifting rod 42 can be connected to the corresponding sensor 7. When each sensor 7 feeds back a signal, each lifting rod 42 stops moving, maintaining the current raising and lowering height, thereby locking relative to the extension plate 3 in the axial direction. Of course, the sensor 7 can also be connected to the power component 5 and the lifting vehicle 1 to ensure that the signal fed back by the sensor 7 restricts the rotation of the extension plate 3 and the movement, raising and lowering functions of the lifting vehicle 1, so as to avoid abnormal situations. The sensor 7 can be selected from proximity switches, limit switches, pressure sensors, etc., without much restriction, all of which fall within the protection scope of this application.

[0053] In addition, please refer to Figure 4The lifting rod 42 has an anti-slip base 45 at its end that abuts against the cable stacking platform 8. The anti-slip base 45 is omnidirectional, allowing its bottom surface to mate with the inclined surface of the cable stacking platform 8 for stable support. The steering component 41 also functions to steer the lifting rod 42. When the lifting rod 42 is not in use, it can be placed against the lower surface of the extension pedal 3 to reduce space occupation; when in use, the lifting rod 42 is rotated out to make it perpendicular to the extension pedal 3. It is worth noting that since the lifting rod 42 needs to move relative to the extension pedal 3 in its axial direction, a through hole or notch can be made on the extension pedal 3 for the lifting rod 42 to pass through, ensuring the normal lifting and lowering of the lifting rod 42.

[0054] The side of the extended platform 3 closest to the working platform 14 is on the same working plane as the working platform 14, ensuring that there is no height difference between the extended platform 3 and the working platform 14 after the extended platform 3 is extended, allowing personnel to walk smoothly. The side of the extended platform 3 is adjacent to the side of the working platform 14, ensuring that no gap occurs between the extended platform 3 and the working platform 14 without affecting the rotation of the extended platform. At the same time, several positioning holes are provided on the side of the extended platform 3 away from the working platform 14, and pins 31 that are inserted into the positioning holes to connect with the cable stacking platform 8 are inserted into the positioning holes, ensuring the relative stability of the extended platform and the cable stacking platform 8 in the horizontal direction.

[0055] The cable laying and lifting equipment of this application also includes a cable laying mechanism 2, please refer to... Figure 1 and Figure 7 The cable-laying mechanism 2 is mounted on the work platform 14. The cable-laying mechanism 2 rotates to release the coiled cable 9. Furthermore, the cable-laying mechanism 2 can be embedded within the work platform 14. The advantage of this embedded design is that it does not affect the basic lifting functions of the lifting vehicle 1. Please refer to... Figure 9 The wire feeding mechanism 2 includes a wire feeding bracket 21 with several wire feeding rollers 24 on it. A wire feeding reel 22 for placing the cable 9 is rotatably mounted on the upper side of each wire feeding roller 24. The wire feeding rollers 24 reduce frictional resistance and support the weight of the wire feeding reel 22 and the cable 9. The wire feeding mechanism 2 also includes a wire feeding motor 23 that drives the wire feeding reel 22 to rotate. The connection between the wire feeding motor 23 and the wire feeding reel 22 is via a pulley or a connecting shaft 26, which drives the wire feeding reel 22 to rotate forward and backward. The wire feeding motor 23 is mounted on the side and can be connected to the output shaft of the wire feeding motor 23 and the connecting shaft 26 via a deflector to drive the wire feeding reel to rotate. Alternatively, an electric wire feeding roller 24 can be used, relying on friction to drive the wire feeding reel 22 to rotate forward and backward, which can reduce the overall height and simplify control.

[0056] To improve the lifting capacity of the cable reel 9 on the lifting platform 1, the cable feeding mechanism 2 can adopt a dual-station design. Anti-slip rubber pads 25 can also be added to the surface of the cable feeding reel 22; please refer to [reference needed]. Figure 10This increases the friction between the cable 9 and the pay-off reel 22. In some embodiments, two outward-applying round rods can be added to the pay-off reel 22. The hollow part of the coiled cable 9 is fitted around the outer circumference of the round rods. The cable 9 is clamped by the outward force of the two round rods, so that the cable 9 is stably placed on the pay-off reel 22 and rotates with the pay-off reel 22.

[0057] The lifting work vehicle 1 also includes a base 11 and a lifting mechanism, please refer to... Figure 1 The base 11 is provided with drive wheels 17 and steering wheels 15. The drive wheels 17 and steering wheels 15 work together to realize the movement function of the lifting vehicle 1, so as to realize forward, backward and steering functions. The lifting mechanism includes an actuator 13 for connecting the base 11 and the working platform 14, and also includes a power source 12 for driving the actuator 13 to perform lifting or lowering actions, so as to drive the working platform 14 to lift. Figure 1 The image shows a scissor-type lifting mechanism combined with a motor lead screw. The power source 12 is a motor, and the actuator 13 is a scissor-type structure. The motor's output shaft and lead screw drive the scissor-type structure to lift, thereby raising and lowering the work platform 14. Alternatively, the power source 12 could be an electric cylinder, directly driving the work platform 14 to lift and lower, achieving precise positioning and low maintenance costs. The lifting mechanism could also be similar to a forklift or elevator, as long as it enables the lifting and lowering of the work platform 14. These are not detailed here, but all fall within the scope of this application.

[0058] The lifting work vehicle 1 in this application also includes a control mechanism, please refer to... Figure 8 The control mechanism includes a first control box 16 and a second control box 18. The first control box 16 is located at a lower position for operation by ground personnel, while the second control box 18 is located on the work platform 14 for operation by personnel in the work area. The first control box 16 can realize the functions of forward, backward, turning, raising, lowering, starting, stopping, and emergency stop of the lifting work vehicle 1. The second control box 18 can realize the raising and lowering of the lifting work vehicle 1, the forward and reverse rotation, speed adjustment, manual and automatic operation, and feedback display of the wire laying mechanism 2, the raising and lowering of the extension platform, feedback display, and the emergency stop function of the entire system. As for the specific control method of the control mechanism, please refer to the existing technology, which will not be elaborated here.

[0059] A fence 6 is also provided on the outer edge of the work platform 14, and a movable fence 6 is provided on the side of the work platform 14 corresponding to the extension pedal 3. After the extension pedal 3 is unfolded, the movable fence 6 is arranged on both sides of the unfolded pedal to ensure that the entire work area can be protected by the fence 6 and prevent workers from falling from heights.

[0060] In use, first, control the lifting vehicle 1 to move to the work area, open the fence 6, and place the coiled cable 9 at the cable reel 22 on the work platform 14; the operator goes up to the work platform 14, closes the fence 6, and raises the work platform 14 to be basically level with the cable stacking platform 8; rotate the support component 4 to open it so that it is perpendicular to the extension pedal 3, start the power component 5 to make the extension pedal 3 rotate toward the cable stacking platform 8; when each support component 4 contacts the cable stacking platform 8, the sensor 7 triggers the command to stop the rotation of the extension pedal 3, and uses the pin 31 to connect the extension pedal 3 and the cable stacking platform 8; start the cable laying mechanism 2 to lay the cable 9.

[0061] This application includes, but is not limited to, cable laying for wind turbine units, and can also be applied to various equipment that requires cable laying, and has broad application prospects.

[0062] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0063] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
