Description

Technical Field

[0001] This utility model belongs to the technical field of cable laying, and in particular relates to a cable laying track vehicle. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Traditional cable laying methods mainly rely on manual handling and manual cable laying, which suffers from low efficiency and the tendency for multiple cables to become tangled when laid simultaneously. While existing railcars can transport cables, they lack effective separators, making it easy for cables to become tangled when laying multiple cables. Furthermore, fixed supports are not suitable for cable trays of different heights, and when multiple cables are laid simultaneously, their laying heights are generally different, which fixed supports cannot accommodate, thus affecting cable laying efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a cable laying track vehicle.

[0004] The technical solution adopted by this utility model is as follows: a cable laying track vehicle, including a track vehicle body, a cable winding mechanism and an adjusting and branching mechanism.

[0005] The bottom of the railcar is equipped with wheels and a power mechanism, while the top forms a load-bearing working surface.

[0006] The cable winding mechanism is located on the bearing working surface and includes a winding roller, which is rotatably configured above the bearing working surface via a bearing seat. Multiple partitions are axially spaced, forming independent winding spaces between the partitions. Multiple winding spaces can wind up multiple sets of cables, which is suitable for laying multiple sets of cables at the same time.

[0007] The cable distribution mechanism includes a lifting column, a crossbeam, and cable distribution frames. The lifting column is positioned at one end of the work surface; the crossbeam is positioned at the lifting end of the lifting column; multiple cable distribution frames are spaced apart along the length of the crossbeam on its outer side wall. Each cable distribution frame has a predetermined bending arc and an arc-shaped through groove along its arc contour. Multiple support rollers are rotatably arranged within the through groove along its arc contour, forming gaps between the rollers for cables to pass through. Cables passing through different gaps can be supported at different heights on different cable distribution frames. The adjustable cable support height range is the vertical height between the fixed end of the cable distribution frame on the outer side of the crossbeam and its extended end, allowing simultaneously laid cables to be supported at different heights and separating the supported cables to reduce the chance of tangling.

[0008] Furthermore, the load-bearing working surface of the main body of the railcar is provided with frame plates on both sides of the travel direction. The frame plates are symmetrically distributed, and the bearing seats are respectively arranged on the corresponding frame plates to raise the winding roller to the corresponding height.

[0009] Furthermore, multiple sets of limiting rollers are provided on the top surface of the frame near one end of the dividing frame. The limiting rollers are rotatably installed via a frame rod. The height of the frame rod corresponding to the limiting roller is preferably different, so that the limiting rollers can be installed at different heights for guiding operations.

[0010] Furthermore, the outer diameter of the support roller is gradually expanded outward from the middle to both ends.

[0011] Furthermore, a support frame is provided at one end of the bearing working surface, and limiting grooves are formed on the inner sides of the two vertical side walls of the support frame. The lifting column is located inside the support frame, and the two ends of the crossbeam slide in the corresponding limiting grooves. The lifting column is suitable for driving the crossbeam to rise and fall along the limiting grooves. The entire distribution frame can rise and fall with the crossbeam to the corresponding height, adapting to the height of cable laying bridges and supports.

[0012] Furthermore, the support frame is provided with reinforcing ribs on its sides that connect to the bearing surface.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows: The cable laying track vehicle proposed by this utility model can simultaneously and separately store multiple groups of cables through the set winding mechanism. Through the set adjusting branching mechanism, the cable laying can achieve dual guidance through the limiting roller and the branching frame, reducing cable swinging and tangling, and simultaneously laying multiple groups of cables separately. In addition, multiple groups of cables can be supported at different heights (the different height range is the vertical distance between the top and bottom of the branching frame) and the cables can be laid at corresponding positions adapted to different cable laying support heights, which can improve the efficiency of cable laying.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0022] like Figures 1-4 As shown, a cable laying track vehicle includes three parts: a track vehicle body 1, a cable winding mechanism 3 disposed on the bearing working surface of the track vehicle body 1, and an adjusting branching mechanism 4. The adjusting branching mechanism 4 is disposed at one end of the bearing working surface on the track vehicle body 1. The cable winding mechanism 3 includes a winding roller 5, which is rotatably mounted on the bearing working surface at a predetermined height via a bearing seat 12. The winding roller 5 extends along the width direction of the bearing working surface and is axially spaced with multiple partitions 19, forming independent winding spaces between the partitions 19 for simultaneously winding multiple types or groups of cables. During cable laying, multiple strands of cable can be laid simultaneously. The adjusting branching mechanism 4 separates and supports the cables laid simultaneously, effectively preventing tangling and knotting between the cables laid simultaneously, improving the efficiency of simultaneous laying, and enabling support at different heights to match cable supports of different heights and positions, ensuring construction efficiency.

[0023] The main body 1 of the railcar can travel along the corresponding track and has a corresponding power mechanism and a control cabinet 18 electrically connected to the drive mechanism, which can facilitate the control of the railcar's movement. The power mechanism and control cabinet 18 for the vehicle's movement are existing technologies and will not be described in detail here.

[0024] In some preferred embodiments, the adjusting branch structure includes a support frame 15 fixedly configured at one end of the working surface of the main body 1 of the railcar. The support frame 15 is assembled into a gantry frame by H-beams, and the two vertical side walls of the gantry frame are formed into limiting grooves 16 by the structure of H-beams.

[0025] It also includes a crossbeam 7 that is raised and lowered within the support frame 15. The two ends of the crossbeam 7 slide through the slide groove, and the bottom of the crossbeam 7 is driven to rise and fall by the lifting column 6. The lifting column 6 can be connected to a hydraulic working system for driving. The hydraulic working system can be configured in the body of the railcar 1. The lifting end of the lifting column 6 is fixedly configured with the corresponding position of the crossbeam 7, and can drive the crossbeam 7 to the corresponding height. The crossbeam 7 has the corresponding support force and the predetermined length.

[0026] It also includes a cable distribution frame 8 configured on the outside of the crossbeam 7. Multiple cable distribution frames 8 are distributed at intervals along the length of the crossbeam 7. The cable distribution frame 8 has a predetermined bending arc and an arc-shaped through groove 9 is opened along its bending direction. Multiple support rollers 10 are rotatably arranged in the arc-shaped through groove 9. The support rollers 10 have a predetermined interval between them to allow cables to pass through. The outer diameter of the support rollers 10 gradually expands outward from the middle to both ends. The cable passes through the gap between the support rollers 10. As the vehicle moves or the worker pulls the cable during laying, it is easy for the cable to pass through the gap for laying.

[0027] The cable distribution frame 8 is an arc shape with a predetermined bending angle, and its end extends to a predetermined length. The height of the crossbeam 7 and the cable distribution frame 8 can be adjusted by lifting the lifting column 6. Because the cable distribution frame 8 is arc-shaped, there is a certain height difference between the end fixed to the crossbeam 7 and the extended end, so that the cable can be supported between the support rollers 10 at different heights according to the laying situation. Moreover, a cable can pass through multiple gaps at different heights to enhance the support and limiting effect, avoid pulling the cable during laying, and prevent excessive cable redundancy. Through the cable distribution frame 8, the cable can be separated at different heights, and the cable can be laid and separated at different heights. It is also convenient to adapt to different height requirements when laying cables at the same time, thus improving the laying efficiency.

[0028] In some preferred embodiments, the take-up roller 5 is mounted on the bearing working surface of the railcar body 1 via a frame plate 11. The frame plates 11 are symmetrically distributed and fixed on both sides of the bearing working surface along its length (railcar movement direction). Bearing seats 12 are respectively arranged at the top of the frame plates 11, and the two ends of the take-up roller 5 are respectively connected to the bearing seats 12. One end of the cable is pulled or fixed to the cable frame, and the other end is wound around the take-up roller 5. When the railcar moves, the take-up roller 5 rotates to release the cable. Furthermore, a motor can be arranged on the frame plate 11, and the output end of the motor is fixedly connected to one end of the take-up roller 5 to provide rotational driving force to the take-up roller 5.

[0029] In this embodiment, preferably, multiple sets of limiting rollers 13 are provided on the top surface of the frame 11 near the end of the cable distribution frame 8. The height of the limiting rollers 13 can be different, and the central axis direction of the limiting rollers 13 and the take-up roller 5 is consistent. The cable can pass through the limiting rollers 13 in sequence and then enter the cable distribution frame 8, further improving the support effect during cable laying and installation. The limiting rollers 13 are supported by the support rods 14 fixedly configured at the corresponding positions on the top of the frame 11, and the two ends of the limiting rollers 13 are rotatably configured with the corresponding support rods 14.

[0030] In addition, in terms of the optimized design of the device, the support rod 14 and the support frame 15 can be fixed at the bottom by fixing plates to ensure the stability of their support operation. Furthermore, the support frame 15 is equipped with reinforcing ribs 17 connected to the working surface of the railcar on the side, which further enhances the stability of the support frame 15.

[0031] In practical use, the cable is wound around different winding spaces of the take-up roller 5. One end of the cable wound in each winding space is passed between the limiting rollers 13 to support the cable. Then, the cable is passed through the appropriate branch frame 8 and the support rollers of appropriate height are selected. The cable is passed between the support rollers and the height of the branch frame 8 is adjusted by the lifting column 6, so as to adjust the cable exit height according to the height of the laying frame. Before the main body of the railcar 1 moves along the track, one end of the cable can be laid on the corresponding cable bracket or pulled manually. When the railcar moves, the cable is pulled and the take-up roller 5 is passively released (or the motor actively releases). As the railcar moves, the cable is straightened. Then the take-up roller 5 rotates to release the cable. After moving to the next laying fixed position, the cable is fixed to the corresponding bracket. Then the main body of the railcar 1 continues to move along the track. During this process, the cable is supported by the limiting roller 13 and the supporting rollers inside the splitter frame 8, and the cable can be separated at different heights by the splitter frame 8, which can adapt to different laying situations of multi-strand cables, improve laying efficiency, and eliminate the need for manual cable carrying.
