Description

Technical Field

[0001] The present invention relates to the technical field of cable laying obstacle avoidance, in particular to a cable laying obstacle avoidance construction device. Background Art

[0002] Cable laying is a critical step in wind farm construction, connecting wind turbines to the power collection system. Traditionally, this process relies on manual cable dragging, which is labor-intensive, inefficient, prone to cable damage, and poses safety risks.

[0003] To improve efficiency, existing technologies utilize mechanized construction, employing a coordinated approach using a payout assembly and a traction assembly. The specific process involves first moving a payout assembly, such as a cable payout rack, to a predetermined position, and then using a traction device to drag the cable head along the predetermined path for installation. This method effectively replaces manual labor, significantly improving construction efficiency and reducing labor intensity.

[0004] However, in actual working environments, construction sites are often not ideally flat. For example, when encountering drainage ditches formed by terrain excavation, traction equipment cannot pass directly through, thus interrupting the cable laying operation and reducing overall construction efficiency.

[0005] Based on this, in order to improve the adaptability and reliability of cable laying, we propose a cable laying obstacle avoidance construction device. Summary of the Invention

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-7 An embodiment of the present invention discloses a cable laying obstacle avoidance construction device, specifically comprising a panel 1 and two bottom beams 2 fixed below the panel 1. Specifically, the bottom beams 2 in this embodiment are configured as rectangular tubes to form an installation space therein. A walking unit 3 is installed on the outside of the bottom beam 2, and an obstacle-crossing beam 4 is movably inserted into the interior of the bottom beam 2. Of course, the obstacle-crossing beam 4 can also be set as a tubular structure, which is movably connected in the above-mentioned installation space. A driving component 5 for driving the obstacle-crossing beam 4 to move linearly is installed inside the bottom beam 2. The obstacle-crossing beam 4 is expanded and retracted by the driving component 5. When obstacle avoidance is not required, the obstacle-crossing beam 4 can be stored to save space. An obstacle-crossing wheel set 6 is installed at the end of the obstacle-crossing beam 4 , and a clamping assembly 7 for fixing the cable is also provided above the panel 1 .

[0022] That is, the clamping assembly 7 provided in the present invention is used to clamp the cable. When the construction work requires dragging the cable, the walking unit 3 drives the entire device to move and drag and lay the cable. During the movement of the device, if a gully is encountered, the obstacle-crossing beam 4 can be extended outward, and the obstacle-crossing wheel group 6 on the obstacle-crossing beam 4 and the walking unit 3 can cooperate to realize the obstacle avoidance operation of the device in the gully.

[0023] In some embodiments, the driving assembly 5 in the present invention includes a first motor 51 fixedly mounted on the end of the bottom beam 2 , a screw rod 52 is fixedly mounted on the shaft end of the first motor 51 , and the screw rod 52 is threadedly connected to the obstacle beam 4 .

[0024] Specifically, when it is necessary to avoid obstacles in the gully, the first motor 51 can be turned on, and the first motor 51 drives the screw rod 52 to rotate. Since the screw rod 52 and the obstacle beam 4 are threadedly connected, the obstacle beam 4 can be pushed to the outside of the bottom beam 2.

[0025] Furthermore, the obstacle-crossing wheel set 6 in this embodiment includes a second motor 61 fixedly mounted on the tail end of the obstacle-crossing beam 4, a rotating wheel frame 62 is fixedly mounted on the shaft end of the second motor 61, and an obstacle-crossing wheel 63 is provided on the rotating wheel frame 62; In the embodiment of the present invention, the second motor 61 is used to drive the rotating wheel frame 62 to rotate, so that the angle of the obstacle-crossing wheel 63 can be adjusted. In this way, in the initial state, the rotating wheel frame 62 can be set horizontally. At this time, the obstacle-crossing wheel 63 does not contact the ground, thereby ensuring the stability of the walking unit 3 under normal travel; Similarly, when obstacles need to be avoided, the rotating wheel frame 62 can be driven to rotate so that the obstacle-crossing wheel 63 faces and contacts the ground. In this way, when the obstacle-crossing beam 4 is extended across the ravine, the obstacle-crossing wheel 63 can be supported on the ground.

[0026] Furthermore, the obstacle-crossing wheel 63 described in the embodiment of the present invention is configured as an electric hub. Through the design of the electric hub, it can be driven to rotate when it is powered on. In addition, in order to realize convenient power supply to the obstacle-crossing wheel set 6 in the embodiment of the present invention, a conductive component 8 is provided between the obstacle-crossing wheel set 6 and the bottom beam 2 in this embodiment.

[0027] Based on the above embodiment, the conductive assembly 8 in this embodiment includes a plurality of sleeves 81 fixedly mounted inside the barrier beam 4. Contacts 83 are movably inserted into the sleeves 81 via springs 82. The ends of the contacts 83 penetrate and extend to the outside of the barrier beam 4. An insulating plate 84 is fixedly mounted on the inner wall of the bottom beam 2 , and a plurality of conductive sheets 85 are fixedly mounted on the end surface of the insulating plate 84 . The contacts 83 are in contact with the conductive sheets 85 .

[0028] It should be noted that the sleeve 81 described in this embodiment is also configured as an insulating member, specifically a plastic member with a steel ring embedded inside. The embedded steel ring is used to ensure its overall force resistance to prevent deformation. In addition, the rear end of the contact 83 is fixedly connected to a wire, which passes through the sleeve 81 and is connected to the obstacle-crossing wheel set 6. Specifically, in this embodiment, the design of a plurality of contacts 83 and a plurality of conductive sheets 85 can be used to power the second motor 61 and the obstacle crossing wheel 63. In this way, the rotation of the second motor 61 and the obstacle crossing wheel 63 can be conveniently controlled when the entire obstacle crossing beam 4 is retracted and expanded. Since a sliding connection type of conductive method is adopted, it not only saves wiring space, but also avoids the problem of cable entanglement, thereby effectively improving the stability and reliability of the power supply to the obstacle crossing wheel group 6.

[0029] To go further, in this embodiment, a wire tube 41 is fixedly installed on the inner side of the obstacle crossing beam 4. The cross-section of the wire tube 41 is a U-shaped structure. The wires of several contacts 83 are connected to the obstacle crossing wheel group 6 along the wire tube 41. That is, in this embodiment, the wire tube 41 is used to constrain the wires connecting the contacts 83 and the second motor 61 and the obstacle crossing wheel 63 to avoid damage caused by contact between the internal wires and the screw rod 52. Of course, the wire tube 41 is installed on the inner side of the obstacle crossing beam 4, and is spaced apart from the screw rod 52 to avoid interference between the screw rod 52 and the wires.

[0030] In some embodiments, the walking unit 3 of the present invention includes a front wheel frame 31 and a rear wheel frame 32; The front wheel frame 31 is fixedly connected to the bottom beam 2, and a front wheel 33 is provided at the bottom thereof; sliding plates 34 are slidably connected to both sides above the panel 1, and the rear wheel frame 32 is fixedly connected to the sliding plates 34, and a rear wheel 35 is provided at the bottom thereof.

[0031] Specifically, the front wheel 33 and the rear wheel 35 described in the present invention are also configured as electric wheel hubs, and the rear wheel frame 32 is slidably connected by a sliding plate 34. The purpose is to adjust the front and rear positions of the rear wheel 35. In this way, when avoiding obstacles in a ravine, the obstacle-crossing wheel 63 can first be extended and supported on the other side of the ravine, and then the device continues to move. When the front wheel 33 approaches the ravine, the rear wheel 35 can also move to the other side of the ravine. At this time, with the help of the double-wheel support of the rear wheel 35 and the obstacle-crossing wheel 63, stable support for the device can be achieved. When the device continues to move, the front wheel 33 can cross the ravine to complete the obstacle avoidance operation.

[0032] Of course, in the embodiment of the present invention, a counterweight block can also be fixedly installed at the end of the obstacle beam 4. Through the design of the counterweight block, the center of gravity of the entire device can be guaranteed when the front wheel 33 avoids obstacles to avoid the problem of the device rolling over. This method is a conventional technical means for technical personnel in the relevant field and will not be elaborated here.

[0033] On the basis of the above embodiment, in order to realize convenient pushing of the sliding plate 34 in this embodiment, a pushing member 36 is fixedly installed above the panel 1, and the pushing member 36 is fixedly connected to the sliding plate 34. As an example, the pushing member 36 in this embodiment can be set as an electric push rod, which is fixed on the panel 1, and its shaft end is connected to the sliding plate 34; A guide groove 37 is provided on the end surface of the sliding plate 34 , and a guide member 38 is fixedly installed above the panel 1 and slides in the guide groove 37 .

[0034] Optionally, the guide member 38 described in this embodiment is configured as a bolt, and the sliding guide of the sliding plate 34 is achieved through the cooperation between the bolt and the guide groove 37 .

[0035] In some embodiments, the clamping assembly 7 of the present invention includes two vertical rods 71 ​​fixedly mounted on the panel 1, and a clamping seat 72 is fixedly mounted on the top of the vertical rods 71; The side of the clamping seat 72 is pinned with an electric push rod 73 , the side of the clamping seat 72 is pinned with a pressure head 74 , and the shaft end of the electric push rod 73 is pinned to the pressure head 74 .

[0036] That is, when the cable needs to be dragged, the cable is first placed on the clamping seat 72. At this time, the electric push rod 73 can be turned on. When the shaft end of the electric push rod 73 is extended, it will drive the pressure head 74 to rotate until the pressure head 74 rotates and presses tightly on the outside of the cable. At this time, the cable can be clamped and fixed. In addition, the present invention adopts the design of two clamping seats 72 and two pressure heads 74 to effectively improve the clamping stability of the cable to avoid the problem of cable falling off.

[0037] Preferably, in this embodiment, a lower positioning plate 75 is fixedly installed on the upper end of the clamping seat 72, and an upper positioning plate 76 is fixedly installed above the pressure head 74. Preferably, the lower positioning plate 75 and the upper positioning plate 76 described in this embodiment are provided with protective patterns on the opposite surfaces, and a groove for positioning the cable can be further provided on the end surface of the lower positioning plate 75. The lower positioning plate 75 and the upper positioning plate 76 described in this embodiment can be connected and fixed to the clamping seat 72 and the pressure head 74 by bolts, so that they can be conveniently replaced and maintained when they are damaged or adapted to different cables.

[0038] It should be noted that, in the embodiment of the present invention, the two bottom beams 2 are horizontally arranged, and a connecting beam 21 is fixedly installed between the two bottom beams 2, and a power supply unit 9 is fixedly installed above the panel 1. The power supply unit 9 is used to supply power to the walking unit 3, the drive assembly 5 and the obstacle-crossing wheel group 6 to ensure that the device can independently perform the cable dragging operation without the need for external wiring and power supply.

[0039] When avoiding obstacles in gullies; When the device encounters a ravine, the obstacle-crossing wheel 63 is first extended so that it is supported on the opposite bank of the ravine; Then, the device continues to move forward until the rear wheel 35 also reaches the other side. At this time, the device is supported by the rear wheel 35 and the obstacle-crossing wheel 63 to maintain stability. On this basis, the front wheel 33 can smoothly cross the ravine and complete the entire obstacle avoidance process.

[0040] In summary, the present invention adopts the design of a retractable and deployable obstacle-crossing beam 4. During the cable laying process, if a gully is encountered and the walking unit 3 cannot cross it, the obstacle-crossing beam 4 can be deployed to allow the obstacle-crossing wheel group 6 to cross the gully, and then cooperate with the walking unit 3 to complete the obstacle avoidance of the gully, which significantly improves the reliability and convenience of cable laying and effectively solves the construction problems under complex terrain.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
