Description

Technical Field

[0001] This utility model relates to the technical field of cable laying devices, and in particular to a convenient and flexible high-voltage cable laying device. Background Technology

[0002] Cables serve as a bridge between power supply equipment and power consumption equipment, playing a role in transmitting electrical energy and having a wide range of applications. High-voltage cables are a type of power cable, mainly used for power transmission and distribution. The possible components of a high-voltage cable, from the inside out, include: conductor, insulation, inner sheath, filler (armor), outer insulation, etc.

[0003] However, in cases such as direct burial downwards or laying upwards on cable racks, cables need to be laid at different angles. Currently, high-voltage cable laying devices are not convenient to adjust during laying, which can easily lead to excessive bending of the cable or inaccurate laying position. Utility Model Content

[0004] The purpose of this invention is to provide a convenient and flexible high-voltage cable laying device, which can easily adjust the laying angle of the cable, facilitate the pulling of the cable in the required direction, and improve the accuracy of the laying work.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A convenient and flexible high-voltage cable laying device includes a cable laying reel and a traction frame. The traction frame pulls the cable in the cable laying reel forward. The traction frame includes a traction base, on which two adjusting frames are connected. Each adjusting frame has a conveying component. The cable passes between the two conveying components and is pulled forward. At least one end of the traction frame has a spline-shaped horizontal bar. The horizontal bar is inserted into a bogie. The bogie is connected to different angles through the horizontal bar, and the guide cable enters or leaves the traction frame at different angles.

[0007] By adopting the above technical solution, the cable in the cable laying reel is pulled forward by the traction frame, and a bogie is set up. The bogie is connected to different angles by horizontal bars, and the guide cable enters or leaves the traction frame at different angles to cope with different cable laying conditions.

[0008] Furthermore, the bogie includes two parallel steering rollers, with a cable passing between the two steering rollers.

[0009] By adopting the above technical solutions, cable guidance is facilitated and damage during cable traction and laying is reduced.

[0010] Furthermore, a limiting plate is provided at one end of the horizontal bar, and a limiting nut is threaded to the other end. The two ends of the bogie abut against the limiting plate and the limiting nut, respectively.

[0011] By adopting the above technical solutions, the positions of the two ends of the bogie are restricted, thereby improving the stability of the bogie operation.

[0012] Furthermore, the bogie also includes two parallel connecting rods, with the two ends of the steering roller connected to the parallel connecting rods respectively.

[0013] By adopting the above technical solution, the connection and fixation of the two parallel connecting rods were achieved.

[0014] Furthermore, the parallel connecting rod includes an outer sleeve rod and an inner insert rod. The inner insert rod is telescopically connected to the outer sleeve rod. One steering roller is sleeved on the outer sleeve rod at both ends, and its end is threaded with a first clamping screw. The inner end of the first clamping screw abuts against the outer periphery of the outer sleeve rod. The other steering roller is connected to the corresponding outer end of the inner insert rod at both ends. The outer end of the outer sleeve rod is threaded with a second clamping screw. The inner end of the second clamping screw abuts against the outer periphery of the inner insert rod.

[0015] By adopting the above technical solution, the positions of the two steering rollers can be controlled separately, adapting to cable laying operations of different specifications and laying directions.

[0016] Furthermore, the traction base is also connected to a spacing adjustment component that drives the two adjustment frames to move closer or further apart.

[0017] By adopting the above technical solution, the distance between the two adjustment frames can be adjusted, adapting to cable traction work of different sizes and specifications, and improving the versatility of the device.

[0018] Furthermore, it also includes a cable-laying frame, which includes a cable-laying base, a fixed frame, and a movable frame. The movable frame is slidably connected to the cable-laying base in a direction close to or away from the fixed frame. Both the fixed frame and the movable frame include an upper roller assembly, which includes at least two rolling shafts. The cable-laying reel includes circular side plates at both ends and abuts against the roller assembly through the circular side plates.

[0019] By adopting the above technical solution, the cable laying frame enables the cable laying reel to rotate and lay cables, facilitating the laying of cables with different diameters and widths.

[0020] Furthermore, the roller assembly includes fixed rollers and adjusting rollers. The adjusting rollers are detachably connected to the corresponding fixed frame or movable frame, and their installation positions maintain different distances from the fixed rollers.

[0021] By adopting the above technical solution, the versatility of cable laying operations for cable laying reels of different diameters has been further improved.

[0022] In summary, this utility model has the following beneficial effects: the cable in the cable laying reel is pulled forward by the traction frame, and a bogie is set up. The bogie is connected to different angles by a horizontal bar, and the cable is guided to enter or leave the traction frame at different angles to cope with different cable laying conditions; the positions of the two bogies can be controlled separately to adapt to cable laying work of different specifications and different laying directions; the cable laying frame realizes the rotation of the cable laying reel on it for cable laying work, and can also facilitate the cable laying work of cable laying reels of different diameters and widths, thus improving the versatility of the device.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0028] A convenient and flexible high-voltage cable laying device, such as Figure 1 As shown, it includes a cable reel 1, a cable laying frame 2, and a traction frame 3. The cable reel 1 is placed on the cable laying frame 2, and the traction frame 3 pulls the cable in the cable reel 1 forward. In some embodiments, the two ends of the cable reel 1 are rotatably connected to the cable laying frame 2, and the cable is laid by being driven to rotate by a motor or by being pulled to rotate by the traction frame 3.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, the cable laying frame 2 includes a cable laying base 21, a fixed frame 22, and a movable frame 23. The fixed frame 22 is fixed on the cable laying base 21, and the movable frame 23 is slidably connected to the cable laying base 21 along the direction close to or away from the fixed frame 22 (the movable frame 23 can slide by means of T-slots and T-blocks, or it can be adjusted by means of screw disassembly and installation at different positions) to accommodate cable laying reels 1 of different widths;

[0030] Both the fixed frame 22 and the movable frame 23 include an upper roller assembly. The roller assembly includes two symmetrically arranged rolling shafts. The cable tray 1 includes circular side plates 11 at both ends and abuts against the roller assembly through the circular side plates 11. The two ends of the rolling shaft are integrally connected to the limiting end plates, so that the circular side plates 11 are limited between the limiting end plates.

[0031] In this embodiment, to further improve the adaptability to cable reels 1 of different diameters, the roller assembly includes a fixed roller 221 and an adjusting roller 222. The adjusting roller 222 is detachably connected to the corresponding fixed frame 22 or movable frame 23, and its installation position maintains a different distance from the fixed roller 221. The adjusting roller 222 can be installed at different positions of the corresponding fixed frame 22 or movable frame 23 by means of screws or plug-in, so as to adjust the distance between the two rollers. The fixed roller 221 can be driven to rotate by a motor to reduce the traction pressure of the traction frame 3, or it can be rotated by the traction frame 3 alone.

[0032] like Figure 1 As shown, the traction frame 3 includes a traction base 31, and two symmetrically arranged adjustment frames 32 are connected to the traction base 31. The adjustment frame 32 is provided with a conveyor. The cable passes through the two conveyor and is pulled forward. The conveyor can be a conveyor belt, a conveyor track, or a number of rollers, etc. The two conveyor clamps the cable, and at least one of the conveyor is driven by a motor to rotate, thereby pulling the cable forward. It can also be replaced by other traction structures. The specific structure is existing technology and will not be described in detail here.

[0033] The two adjustment frames 32 can be guided and installed on the traction base 31 by means of a slide rail or other device. The traction base 31 is also connected to a spacing adjustment component that drives the two adjustment frames 32 to move closer or further apart. In this embodiment, the spacing adjustment component includes a lead screw in the traction base 31 and several parallel rods parallel to the lead screw. The lead screw has two opposite threads, which are respectively threaded into the corresponding adjustment frames 32. The lead screw is driven to rotate by a motor, which drives the two adjustment frames 32 to move closer or further apart. It can also be replaced by a linear drive component such as a linear module.

[0034] like Figure 3As shown, the traction frame 3 has a spline-shaped horizontal bar 4 at at least one end (which can also be set as a regular polygonal prism). The horizontal bar 4 is inserted into the bogie 41 through the spline part. The bogie 41 is installed at different angles through the horizontal bar 4, so that the guide cable enters or leaves the traction frame 3 at different angles. In this embodiment, the horizontal bar 4 is fixed at both ends of the traction frame 3 to adapt to different working environments and facilitate the placement and installation of the traction frame 3 and the cable release frame 2.

[0035] One end of the horizontal bar 4 is fixed to the limiting plate 42, which is fixedly connected to the traction frame 3. The other end of the horizontal bar 4 is threadedly connected to the limiting nut 43, so that the two ends of the bogie 41 abut against the limiting plate 42 and the limiting nut 43 respectively. The bogie 41 includes two parallel steering rollers 411 and two parallel connecting rods 412. The two ends of the steering rollers 411 are respectively connected to the corresponding parallel connecting rods 412 and form a rectangle. The cable passes through the two steering rollers 411. (The limiting plate 42 can also be set with two parallel ones, connected to the corresponding horizontal bar 4 on the same side, so that the two parallel connecting rods 412 can be connected more stably through the horizontal bar 4. Alternatively, a sleeve can be connected between the two parallel connecting rods 412 and fixed to one side of the limiting plate 41 through the sleeve.)

[0036] like Figure 3 As shown, in this embodiment, in order to facilitate the adjustment of the positions of the two steering rollers 411 as needed, the parallel connecting rod 412 includes an outer rod 413 and an inner rod 414. The inner rod 414 is telescopically connected to the outer rod 413. The shaft ends of one steering roller 411 are sleeved on the outer rod 413, and its ends are threaded with a first clamping screw 415. The inner end of the first clamping screw 415 abuts against the outer periphery of the outer rod 413, and the position of the steering roller 411 is fixed by the first clamping screw 415.

[0037] The other steering roller 411 is fixedly connected to the outer ends of the corresponding inner rod 414 at both ends. The outer peripheral wall of the outer end of the outer rod 413 is threaded with a second clamping screw 426. The inner end of the second clamping screw 426 is pressed against the outer periphery of the inner rod 414, and the position of the steering roller 411 is fixed by the second clamping screw 426.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
