Description

Technical Field

[0001] This utility model relates to a large-volume cable reel vertical deployment vehicle based on a flatbed trailer, which can be used for the vertical deployment of large-volume cable reels in construction sites. Background Technology

[0002] During the construction of underground cables for wind farm collector lines, medium-voltage cable sections are typically quite long to reduce the number of cable joints. Because the cables used are generally of larger specifications and higher voltage levels, the cable reels are also quite long, with the largest single reel reaching a diameter of 4.3 meters and a weight of up to 15 tons. If conventional cable reels are used to lay cables on the ground between wind turbines in the wind farm area, using cable laying machines or manual labor with winches for traction, pulleys and other equipment need to be prepared before laying. Furthermore, a large amount of manual labor is required, and a separate generator is needed to power the laying equipment. This not only results in extremely low laying efficiency but also high construction costs.

[0003] Therefore, there is a need for a vertical cable reel laying machine that can be used for mobile transport and cable laying within the wind farm area. This machine must meet three requirements: First, the platform size of the transport equipment must be able to carry large-volume, heavy-tonnage cable reels and leave working space for 5-8 people; second, the cable reels must be vertically fixed to the transport equipment and be secure and reliable during transport; and third, the cable reels can be freely rotated for laying during transport. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the background technology mentioned above, and to provide a large-volume cable reel vertical deployment vehicle based on a flatbed trailer, which can be used for mobile transportation and cable deployment in wind farm areas, while the transportation equipment can adapt to the complex terrain of wind farm areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A large-volume vertical cable reel deployment vehicle based on a flatbed trailer includes a flatbed trailer, a cable reel deployment frame fixedly mounted on the flatbed of the flatbed trailer, a vertical cable reel rotatably mounted on the cable reel deployment frame, at least one deployment rolling bracket fixedly mounted in front of the cable reel deployment frame, and a crash barrier fixedly mounted on the rear side of the cable reel deployment frame.

[0006] Furthermore, the cable reel rack includes a base plate, on which two symmetrical trapezoidal supports are provided. Each trapezoidal support is provided with a crossbeam, and each crossbeam is provided with a rolling seat. A through-rotor is provided between the two rolling seats, and the vertical cable reel is rotatably mounted on the through-rotor.

[0007] Furthermore, each of the two trapezoidal supports is equipped with a crossbar, and each of the two crossbars is equipped with a hydraulic jack. The two hydraulic jacks are respectively supported under the corresponding crossbeams and drive the crossbeams to move up and down. The crossbeams and trapezoidal supports are provided with corresponding positioning holes and are fixed by rivets.

[0008] Furthermore, the trapezoidal support is constructed by welding vertical rods, diagonal rods, and connecting rods. The lower end of the vertical rod extends out of the base plate, and a diagonal support rod is welded between the diagonal rod and the vertical rod.

[0009] Furthermore, there are 1 to 5 deployment rolling supports, each of which is composed of supporting steel and rolling steel pipes, with the supporting steel welded to the flatbed of the flatbed trailer.

[0010] Furthermore, a counterweight is provided on the flatbed of the flatbed trailer.

[0011] This utility model is a large-volume cable reel vertical deployment vehicle modified from a flatbed trailer. Compared with existing technologies, its advantages are as follows: 1. Highly efficient and labor-saving, overcoming the low efficiency of conventional vertical cable laying, reducing the number of secondary site transfers and labor costs, improving cable laying efficiency, and lowering construction costs. The flatbed trailer chassis combines load-bearing capacity with flexibility and strong terrain adaptability; 2. This vertical cable reel deployment vehicle has a short modification cycle and low cost. It utilizes existing equipment, adds a modular cable rack, is easy to disassemble, and will not damage the structure of the original flatbed trailer. Attached Figure Description

Detailed Implementation

[0013] The present invention will be described in detail below with reference to specific implementation examples. The following implementation examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0014] like Figure 1 — Figure 5As shown, this utility model relates to a large-volume vertical cable reel deployment vehicle based on a modified flatbed trailer, including a flatbed trailer 1. A cable reel deployment frame 2 is fixedly installed on the flatbed of the flatbed trailer 1. A vertical cable reel 3 is rotatably installed on the cable reel deployment frame 2. At least one deployment rolling bracket 5 is fixedly installed in front of the cable reel deployment frame 2. A crash barrier 6 is fixedly installed on the rear side of the cable reel deployment frame 2.

[0015] This solution utilizes an existing flatbed trailer for modification, adding a cable reel laying frame 2, along with auxiliary equipment such as rolling supports, crash barriers, and counterweights. It has a strong carrying capacity and can travel flexibly and smoothly on complex terrain roads while carrying cable reels. During the laying of cable 8, due to the large size and heavy weight of the cable, before the cable 8 enters the cable trench, the rolling supports 5 are deployed to protect the cable 8 during transport. At the same time, crash barriers 6 are provided to prevent impacts and protect the cable reel.

[0016] This solution can support large-volume, high-tonnage cable reels and accommodate vertical deployment. It adapts to complex terrain, ensuring robust, stable, and flexible transport. Furthermore, the relatively large width of the flatbed trailer platform effectively meets the space requirements for simultaneous operation by construction personnel. The modification is simple, requiring short time and low cost, and does not damage the original structure of the flatbed trailer. It is easy to disassemble and highly practical.

[0017] Furthermore, the cable reel rack 2 includes a base plate 10, on which two symmetrical trapezoidal supports 11 are provided. Each trapezoidal support is provided with a crossbeam 12, and each crossbeam 12 is provided with a rolling seat 13. A through-shaft 15 is provided between the two rolling seats 13. The vertical cable reel 3 is rotatably mounted on the through-shaft 15. The trapezoidal support structure is stable and has good support strength.

[0018] Furthermore, each of the two trapezoidal supports 11 is equipped with a crossbar 16, and each of the two crossbars 16 is equipped with a hydraulic jack 17. The two hydraulic jacks respectively support the corresponding crossbeams 12 and drive the crossbeams 12 to move up and down. The crossbeams 12 and the trapezoidal supports 11 are provided with corresponding positioning holes 18 and are fixed together by rivets 19. In actual production, vertical cable reels come in various sizes. Therefore, the height of the crossbeams can be adjusted by using hydraulic jacks, thereby adjusting the height of the through-core shaft to make it compatible with the vertical cable reel. After the height adjustment is completed, the rivets are inserted into the corresponding positioning holes for positioning and fixing to prevent the through-core shaft from shifting.

[0019] Furthermore, the trapezoidal support 11 is constructed by welding together a vertical rod 21, a diagonal rod 22, and a connecting rod 23. The lower end of the vertical rod 21 extends out of the base plate 10 and can be fixed to the flatbed of the flatbed trailer 1, making the trapezoidal support more stable. A diagonal support rod 24 is welded between the diagonal rod 22 and the vertical rod 21. The vertical rod 21, diagonal rod 22, connecting rod 23, and diagonal support rod 24 are all made of structural steel and are welded together, providing good support strength.

[0020] Furthermore, the aforementioned deployment and rolling support 5 consists of 1 to 5 units, typically 3 or 4 units. The deployment and rolling supports are arranged from front to back, with the height increasing as needed, depending on the actual situation. Each deployment and rolling support 5 is composed of a supporting steel profile 51 and a rolling steel pipe 52. The supporting steel profile 51 is welded to the flatbed of the flatbed trailer 1. The steel profile and steel pipe can be purchased directly from the market and directly welded for installation, saving time and effort.

[0021] Furthermore, a counterweight 7 is provided on the flatbed of the flatbed trailer 1. With the counterweight, the vehicle can be transported smoothly and flexibly in complex terrain.

[0022] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
