Description

Technical Field

[0001] The present invention relates to the technical field of cable wiring equipment, in particular to wiring equipment for indoor and outdoor narrow cable trenches, ducts and pipe corridors. Background Art

[0002] Substations and other industrial plants require extensive data transmission cabling. This is often done indoors and outdoors in infrastructure environments such as cable trenches, wiring troughs, and pipeline corridors. Manual wiring, coupled with a manual wire guide, is often used in these narrow, low-profile environments.

[0003] Cable trench construction requires precast concrete panels, which are particularly heavy, labor-intensive, and slow to install. They also hinder access to narrow trenches and corridors, making construction difficult. Existing equipment is generally only suitable for wide trenches and corridors. Due to its inherent size and the rigid shape of its winding reels, it cannot fit within the narrow spaces of cable trenches and corridors. Wiring in pipelines and wiring troughs requires pulling cables with small traction equipment, increasing the risk of damage. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention proposes a wiring device that can pass through obstacles by changing its own shape.

[0005] The present invention comprises:

[0006] A power control unit having an independently controllable robotic arm that changes its posture by adjusting the rotation angle of the reducer to achieve the device's pseudo-stepping motion and posture adjustment;

[0007] A deformation guide component is provided with a power control unit on both sides. The two ends of the deformation guide component are connected to telescopic drive wheels, and the four sides are connected to support rollers through support roller connecting ends. The length and swing angle of the telescopic drive wheel and the support roller are adjusted by the transmission ratio, thereby changing the external shape of the flexible drive wheel;

[0008] The flexible drive wheel is nested in the support profile formed by the telescopic drive wheel and the support roller. The flexible drive wheel realizes the cable pay-out and take-up action by self-rotation. At the same time, its outer circular surface can fit with the top or bottom of the cable trench and gallery to provide auxiliary power for crossing.

[0009] The flexible winding chamber is formed by the winding chamber of the telescopic driving wheel, the winding chamber of the tape support roller and the flexible winding chamber of the flexible driving wheel, and is used to store and guide the winding and release of the cable;

[0010] Through the coordinated action of the power control unit and the deformation guide component, the device can change its own shape to adapt to different wiring environments, including narrow cable trenches, pipe corridors and narrow pipes, and achieve precise cable pay-out control through the rotation of the flexible drive wheel.

[0011] Beneficial effects of the present invention:

[0012] 1. Efficient wiring and improved construction efficiency

[0013] Automated operation: The automatic wiring equipment of the present invention realizes the automation of the wiring process through the coordinated work of the mechanical arm and the flexible driving wheel, eliminating the need for manual threading and greatly reducing construction time and labor costs.

[0014] Rapidly traverse complex environments: The device can automatically adjust its shape according to the shape and size of narrow spaces such as cable trenches and pipe corridors, quickly traversing obstacles and avoiding the construction difficulties and inefficiencies caused by space limitations in traditional wiring methods.

[0015] 2. Strong adaptability and wide range of applications

[0016] Multi-environment applicability: This device is not only suitable for narrow spaces such as indoor and outdoor cable trenches, wiring troughs and pipe corridors, but can also adapt to different wiring scenarios such as narrow pipes and low channels by adjusting its posture, showing extremely high versatility.

[0017] Flexible shape adjustment: Through the synergistic effect of the telescopic drive wheel, the support roller and the flexible drive wheel, the device can change its shape to adapt to different wiring channel shapes, breaking through the bottleneck of traditional wiring equipment that cannot be used in narrow spaces due to size and shape limitations.

[0018] 3. Precise routing and resource optimization

[0019] Precise cable pay-off control: The self-rotation function of the flexible drive wheel is similar to that of a crawler belt, which enables the cable to rotate equidistantly during the movement of the equipment, achieving precise cable pay-off, avoiding loose cables or excessive stretching, and ensuring wiring quality.

[0020] Optimized resource utilization: The equipment can automatically adjust its posture and movement according to the wiring environment, reducing cable damage and waste caused by improper construction, and improving the utilization rate of cable resources.

[0021] 4. Improved security and reliability

[0022] Reduced manual intervention: Traditional cabling construction requires frequent entry into narrow, low cable trenches and pipe corridors, posing a safety hazard. This equipment reduces the frequency of manual entry into hazardous areas through automated operation, significantly improving construction safety.

[0023] Real-time monitoring and auxiliary functions: The equipment is equipped with lighting equipment, ranging sensors and functional robotic arms, which can monitor the wiring environment in real time and assist operators in precise wiring, further improving the safety and reliability of construction.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0040] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 12 As shown, the automatic wiring equipment provided by the embodiment of the present application includes a power control unit 1, which is located on both sides of the deformation guide component 2. The mechanical arm connection drive end 11 of the power control unit 1 is installed with a reducer mechanical arm 3. The middle of the deformation guide component 2 is a control connection end 23, which is used to connect the power control unit 1. The telescopic drive wheel connection ends 21 at both ends of the deformation guide component 2 are installed with a telescopic drive wheel 4. The deformation guide component 2 is connected to the support roller 5 through the support roller connection end 22 on all sides. The flexible drive wheel 6 is nested in the support profile formed on the telescopic drive wheel 4 and the support roller 5. The winding bin 42 of the telescopic drive wheel 4 and the winding bin 53 of the support roller 5 and the flexible winding bin 61 of the flexible drive wheel 6 together form a space that follows the deformation of the flexible drive wheel, the flexible winding chamber 7.

[0041] like Figure 8 and Figure 9 As shown, in a certain embodiment, the telescopic drive wheel 4 is connected to the connecting end 22 of the deformation guide component 2 through a telescopic rod 43, and the axial distance between the telescopic drive wheels 4 at both ends and the deformation guide component 2 is controlled internally by a worm gear or hydraulic drive.

[0042] like Figure 4 and Figure 9 As shown, in a certain embodiment, the support roller 5 is distributed and fixed around the central axis of the deformation guide component 2 through a swing arm support 51, and the swinging motion is formed by the internal worm gear or hydraulic drive swing support 51, and the piston-type power rod 52 provides support force to reduce the swinging resistance.

[0043] like Figure 9 and Figure 10 As shown, in one embodiment, the telescopic drive wheel 4 and the support roller 5 adjust the required length and swing angle through the transmission ratio, thereby changing the external shape of the flexible drive wheel 6. The outer circumference of the flexible drive wheel 6 is fixed, and the shape change simultaneously changes the shape of the flexible winding chamber 7.

[0044] like Figure 5 and Figure 6As shown, in one embodiment, the power control unit 1 has a reducer arm 3 mounted on its arm-connected drive end 11. Each reducer arm 3 can be individually controlled, with the position changed by adjusting the reducer rotation angles in the parallel-axis reducer main arm 31, the cross-axis reducer joint 32, and the cross-axis reducer extension arm 33. Each front and rear reducer arm 3 independently adjusts the reducer angle activation sequence to achieve a pseudo-stepping stride.

[0045] Furthermore, the telescopic drive wheel 4 drives the flexible drive wheel 6 to rotate, and the cables and wires wound in the flexible winding chamber 7 rotate with the flexible drive wheel 6 to complete the payout and reeling action. Driving the flexible drive wheel 6 to rotate acts as a crawler track, changing the shape of the flexible drive wheel 6 so that its outer surface conforms to the top or bottom of the cable trench and corridor, providing auxiliary power for crossing. The cables and wires rotate equidistantly along the outer surface of the flexible drive wheel 6, rolling equidistantly along the contact surface between the outer surface of the flexible drive wheel 6 and the travel path, achieving precise payout and length control.

[0046] Furthermore, the function expansion drive end 12 of the power control unit 1 can be expanded to install the function robot arm 9, see Figure 10 The grabbing function accessory set can complete actions such as hanging cables and moving obstructions, and can also expand other functions such as ranging and real-time monitoring.

[0047] like Figure 13 and Figure 14 As shown in Example 1, the cable trench and pipe gallery are wired in an external posture.

[0048] Each reducer arm 3 can be independently controlled, changing its posture by adjusting the reducer rotation angles within the parallel-axis reducer main arm 31, the cross-axis reducer joint 32, and the cross-axis reducer extension arm 33. The reducer arm 3 adjusts the reducer angles to create a quadrupedal stance or lowers its front-to-back position to create a low-lying stance. The telescopic drive wheel 4 and the support roller 5 adjust their length and swing angles through the transmission ratio, changing the external shape of the flexible drive wheel 6 so that its outer circumference conforms to the top of the cable trench, providing auxiliary power for crossing.

[0049] Furthermore, the front and rear two pairs of reducer manipulator arms 3 can be replaced with double-arm single-leg reducer manipulator arms 8, achieving the advantage of easy operation of large loads and meeting the needs of more working environments. Figure 11 .

[0050] The cables are laid by winding themselves or pulling them over short distances. There are identical flexible cable storage bins on both sides of the fuselage, which can change shape with the fuselage, keeping the outer circumference unchanged and preventing the cables from becoming loose during transportation.

[0051] The functional robotic arm 9 grasps the functional accessory assembly to perform actions such as placing cables and removing obstructions. It can also be controlled by a handheld remote control, allowing users to observe the environment through real-time video and make corresponding adjustments. Furthermore, lighting equipment and distance sensors are installed around the main device to assist in operation and provide real-time notification of distance changes.

[0052] The reducer manipulators 3 adjust their respective reducer angles and activate in sequence, completing the pseudo-stepping action. They can also tilt their angles to allow the flexible drive wheel 6 to rest on the floor inside the cable trench. The reducer manipulators 3 rest on the top surface of the trench cover to aid balance. This allows the flexible drive wheel 6 to pass through narrow areas within the trench.

[0053] like Figure 15 As shown, embodiment 2, narrow and long pipe shuttle shape posture wiring method.

[0054] Each front and rear reducer arm 3 is adjusted to a horizontal orientation, with the ball wheel component 34 perpendicular to the traversing surface to provide auxiliary support. The telescopic drive wheel 4 is adjusted to an optimal length, and the support roller 5 is swung parallel to the reducer arm 3. The main body of the cable trench automatic wiring device is modified to be suitable for traversing narrow and long pipe shapes.

[0055] In summary, the present invention realizes the flexible movement and precise wiring of equipment in complex environments through the organic combination of a power control unit, a deformation guide component and a flexible drive wheel. The power control unit of the equipment has a function-expanded drive end, which can be installed with a grabbing robot arm, a ranging sensor, a real-time monitoring device, etc., and can realize multiple functions such as hanging cables and moving obstructions to meet more construction needs.

[0056] The equipment is capable of stable operation in complex environments such as wet, narrow, and low-rise environments. Its optimized mechanical structure and drive system provide excellent durability and reliability. Automated operation also reduces wear and tear on the equipment, lowering maintenance frequency and costs while extending its service life.

[0057] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
