Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 7A cable laying device for high-speed railways includes a cable laying vehicle 1, which is equipped with at least one load-bearing guide mechanism 4 and at least one telescopic guide mechanism 9.

[0023] The load-bearing guide mechanism 4 includes a column 25 rotatably mounted on the wire feeding cart 1. A pitch sleeve 26 is rotatably connected to the upper end of the column 25. A pitch adjusting cylinder 27 is rotatably connected to the middle of the column 25. The piston rod of the pitch adjusting cylinder 27 is rotatably connected to the pitch sleeve 26. A telescopic rod 29 is slidably mounted inside the pitch sleeve 26. A telescopic adjusting cylinder 28 is fixedly connected to the outer wall of the pitch sleeve 26. The piston rod of the telescopic adjusting cylinder 28 is fixedly connected to the telescopic rod 29. The telescopic rod 29 is connected to the first frame 33.

[0024] The telescopic guide mechanism 9 includes a plurality of frames 11 arranged in sequence, wherein the first frame 11 is rotatably connected to the wire feeding carriage 1, and adjacent frames 11 are connected by a movable connector 12.

[0025] In use, the load-bearing guide mechanism 4 or the telescopic guide mechanism 9 is selected to guide the cable according to the type of cable being laid. Specifically, when the cable diameter is small and the weight is light, the telescopic guide mechanism 9 is used to guide the cable. When the cable diameter is large and the weight is heavy, the load-bearing guide mechanism 4 is used to guide the cable. Obviously, the load-bearing guide mechanism 4 can guide cables with larger diameter and heavier weight, and it can also guide cables with smaller diameter and lighter weight. When the load-bearing guide mechanism 4 guides the cable, the pitch adjustment cylinder 27 is first adjusted according to the cable laying position. During the operation of the pitch adjustment cylinder 27, the pitch angle of the pitch sleeve 26 is adjusted. Then, the telescopic adjustment cylinder 28 is adjusted. During the operation of the telescopic adjustment cylinder 28, the telescopic rod 29 is extended from the pitch cone 26, thereby adjusting the height of the first frame 33. By adjusting the pitch adjustment cylinder 27 and the telescopic adjustment cylinder 28, the position of the first frame 33 can be precisely controlled so that it can pass over the cable laying position during the movement of the cable laying trolley 1. Then, the cable can be passed through the first frame 33. The cable is in the first frame 33, and its weight will act on the first frame 33. The first frame 33 is supported by the telescopic rod 29 and the pitch sleeve 26, and the pitch sleeve 26 is supported by the pitch adjustment cylinder 28. Therefore, the load-bearing guide mechanism 4 has a stronger load-bearing capacity and can effectively ensure the stability of heavy cables during the laying process. When using the telescopic guide mechanism 9 to guide the cable, first pull the telescopic guide mechanism 9 to arrange all the frames 11 in sequence, such as... Figure 1 and 2As shown, the cables are then passed through all frames 11 in sequence. After the cables are laid, the telescopic guide mechanism 9 can be folded up and rotated to the top of the cable laying cart 1. For the load-bearing guide mechanism 4, the column 25 can be rotated, which will drive the pitch sleeve 26 to rotate to the top of the cable laying cart 1, thereby retracting the load-bearing guide mechanism 4 as well. Figure 5 , 6 As shown in Figure 7, this allows the wire feeding vehicle 1 to move flexibly, preventing the telescopic guide mechanism 9 and the load-bearing guide mechanism 4 from being damaged by collisions with surrounding objects during the movement.

[0026] The present invention can select either the telescopic guide mechanism 9 or the load-bearing guide mechanism 4 to support the cable according to the type of cable to be laid, which is highly versatile. In addition, when the cable is not to be laid, both the telescopic guide mechanism 9 and the load-bearing guide mechanism 4 can be retracted to the top of the cable laying cart 1 for fixation, without exceeding the cable laying cart 1, thereby avoiding damage during the movement of the cable laying cart 1 and ensuring that the cable laying cart 1 can move smoothly.

[0027] The specific structure of the cable laying vehicle 1 is as follows: The cable laying vehicle 1 includes two power control systems 5 and at least two sets of traveling wheels 3. Each set of traveling wheels 3 contains at least two wheels. The power control systems 5 are connected to all traveling wheels 3. Guide wheels 2 are rotatably mounted on the sides of the traveling wheels 3 and are horizontally positioned. A cable reel 7 is rotatably mounted on the cable laying vehicle 1. A traction mechanism 6 is installed between the cable reel 7 and the load-bearing guide mechanism 4 or the telescopic guide mechanism 9. The two power control systems 5 can operate independently, thereby driving the cable laying vehicle 1 to move forward or backward without turning around, making it more flexible and convenient. The guide wheels 2 can guide the direction of the cable laying vehicle 1. Specifically, when the high-speed rail track has not yet been laid, the guide wheels 2 can be made to contact the track slab, thereby controlling the direction of travel of the cable laying vehicle 1 by utilizing the cooperation of the track slab and the guide wheels 2. This allows the cable laying work to be carried out before the track is laid, which is more in line with actual construction needs. The traction machine 6 is used to unload the cable from the cable reel 7 and transport it to the load-bearing guide mechanism 4 or the telescopic guide mechanism 9. This is a conventional technology in the field and will not be described in detail here.

[0028] A fixed guide mechanism 8 is provided between the traction machine 6 and the load-bearing guide mechanism 4, and between the traction machine 6 and the telescopic guide mechanism 9. The structure of the fixed guide mechanism 8 is similar to that of the telescopic guide mechanism 9, both including multiple frames. However, all the frames of the fixed guide mechanism 8 are fixedly set and distributed along a straight line or arc. The fixed guide mechanism 8 can guide the cable extending from the traction machine 6 into the load-bearing guide mechanism 4 or the telescopic guide mechanism 9, and improve the stability of the cable on the cable laying vehicle 1.

[0029] A passive rotary support platform 10 is provided on the wire feeding carriage 1. The passive rotary support platform 10 includes a tray that is rotatably set on the wire feeding carriage 1. The first frame 11 of the telescopic guide mechanism 9 is fixedly connected to the tray.

[0030] To facilitate the retraction of the load-bearing guide mechanism 4 onto the wire-feeding cart 1, the load-bearing guide mechanism 4 includes an active rotary support platform 24 fixedly mounted on the wire-feeding cart 1, with a column 25 vertically fixed on the active rotary support platform 24. The active rotary support platform 24 includes a drive motor and a mounting platform driven by the drive motor. The column 25 is vertically fixed on the mounting platform. Through the active rotary support platform 24, in addition to quickly retracting the load-bearing guide mechanism 4 onto the wire-feeding cart 1, the direction of the pitch sleeve 26 can also be adjusted, thereby further improving the flexibility of the load-bearing guide mechanism 4 and making it easier to use.

[0031] For heavy cables, in order to ensure that the cables can be laid smoothly to the predetermined position, the position of the first frame 33 needs to be as low as possible. This results in the position of the first frame 33 being lower than the cable laying trolley 1. In order to ensure that the load-bearing guide mechanism 4 can be smoothly retracted above the cable laying trolley 1 and to prevent the first frame 33 from hitting the cable laying trolley 1, the telescopic rod 29 is fixedly connected to two parallel positioning plates 43. The two positioning plates 43 are rotatably connected to a rotating shaft 44. The positioning plates 43 are provided with at least two pin holes 46 distributed along the circumference of the rotating shaft 44. The first frame 33 is fixedly connected to a suspension rod 30. The suspension rod 30 is fixedly connected to an extension plate 47. The extension plate 47 extends between the two positioning plates 43 and the rotating shaft 44 passes through the extension plate 47. The extension plate 47 is also provided with positioning pins 45 that match the pin holes 46. By adjusting the fit between the positioning pin 45 and the pin hole 46, the tilt angle of the suspension rod 30 can be adjusted. During the cable laying process, the suspension rod 30 is kept vertical to ensure that the cable can be supported and guided smoothly. After the cable laying is completed, the suspension rod 30 is tilted to drive the first frame 33 to avoid the cable laying trolley 1, thereby ensuring that the load-bearing guide mechanism 4 can be smoothly stored on the cable laying trolley 1.

[0032] To further enhance the flexibility of the load-bearing guide mechanism 4 and precisely control the direction of the cable, a connecting plate 31 is fixedly connected to the suspension rod 30. The connecting plate 31 has at least one guide hole 32, which is an arc-shaped hole extending along the circumference of the suspension rod 30. The connecting plate 31 is fixedly connected to the first frame 33 by at least one fastening bolt, which passes through the guide hole 32. By adjusting the position of the fastening bolt in the guide hole 32, the rotation angle of the first frame 33 can be adjusted. Specifically, during cable laying, the rotation angle of the first frame 33 is a horizontal rotation angle. By controlling the direction of the first frame 33, the cable exit direction can be adapted, reducing the lateral force on the cable.

[0033] Because the load-bearing guide mechanism 4 needs to support cables with significant weight, to further enhance its load-bearing capacity and thus improve cable stability, the load-bearing guide mechanism 4 includes a mounting rod vertically fixed to the cable-laying cart 1. The mounting rod is located to the side of the column 25, and a rotating sleeve 36 is rotatably fitted onto the mounting rod. A bearing rod 37 is fixedly connected to the rotating sleeve 36, and a second frame 40 is fixedly connected to the bearing rod 37. The bearing rod 37 is positioned between the traction machine 6 and the pitch sleeve 26. After the cable extends from the traction machine 6, it first passes through the second frame 40. The combination of the bearing rod 37, the pitch sleeve 26, and the telescopic rod 29 provides support for the cable, thereby improving cable stability. To enhance the load-bearing capacity of the bearing rod 37, a reinforcing plate 38 is connected between the bearing rod 37 and the rotating sleeve 36, and the reinforcing plate 38 is located below the bearing rod 37.

[0034] The second frame 40 is specifically connected to the support rod 37 as follows: two clamping blocks 39 are fixedly connected to the second frame 40. The two clamping blocks 39 are located on both sides of the support rod 37, and the two clamping blocks 39 are connected by at least one tension bolt. The tension bolt can control the clamping or loosening of the two clamping blocks 39, thereby allowing the second frame 40 to move on the support rod 37, thus improving flexibility and meeting the needs of more working conditions.

[0035] The specific structure of the movable connector 12 is as follows: The movable connector 12 includes a first connecting plate 15 and a second connecting plate 20. The first connecting plate 15 and the second connecting plate 20 are respectively fixedly connected to two adjacent frames 11. The first connecting plate 15 is fixedly connected to two parallel first support plates 16. A rotating shaft 17 is rotatably connected between the two first support plates 16. The rotating shaft 17 is fixedly connected to two parallel swing plates 18. The two swing plates 18 are jointly fixedly connected to a connecting sleeve 22. A connecting pin 23 passes through the connecting sleeve 22. The second connecting plate 20 is fixedly connected to two second support plates 21. The connecting pin 23 passes through the two second support plates 21. The two swing plates 18 rotate around the axis of the rotating shaft 17 and can also rotate around the connecting pin 23, thereby causing the relative position of the first connecting plate 15 and the second connecting plate 20 to change, thus changing the relative positional relationship of the two adjacent frames 11, and ultimately enabling the telescopic guide mechanism 9 to switch between the retracted state and the extended state. In order to improve the structural strength of the movable connector 12 and thus ensure the overall structural strength of the telescopic guide mechanism 9, at least one reinforcing rod 19 is fixedly connected between the two swing plates 18.

[0036] To ensure the cable can move smoothly within the frame 11, at least two first horizontal guide rollers 13 and at least two first vertical guide rollers 14 are rotatably arranged within the frame 11. At least two second horizontal guide rollers 34 and at least two second vertical guide rollers 35 are rotatably arranged within the first frame 33. At least two third vertical guide rollers 41 and at least two third vertical guide rollers 42 are rotatably arranged within the second frame 40. Both the vertical and horizontal guide rollers are used to limit and support the cable. Because both the vertical and horizontal guide rollers are freely rotatable, they rotate with the cable, thus not obstructing its movement and ensuring smooth cable movement while preventing damage to the cable surface.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
