DETAILED DESCRIPTION

[0052] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0053] The main technical problems solved by this embodiment are: in the prior art, the optical cable laying process requires separate grooving, and the optical cable needs to be simply fixed after being manually pulled into the groove, and then backfilled with soil, resulting in high labor intensity and low laying construction efficiency.

[0054] To this end, the main inventive concept of this embodiment is as follows: based on the existing construction steps: excavating trenches, laying optical cables, and backfilling soil into the trenches, the above multiple steps are integrated into one device, that is, through this embodiment, the above optical cable laying steps can be completed at one time, reducing manpower participation, reducing labor intensity, and improving laying efficiency. At the same time, considering the overall structural linkage, the equipment cost is reduced as much as possible, which is more conducive to actual promotion and use. Please refer to the following embodiments for details.

[0055] However, although the following embodiments mention the laying of optical cables, it is conceivable that the device is also applicable to the laying of materials such as electrical cables and soft pipes, and no excessive restrictions are made here.

[0056] like Figures 1-8As shown, this embodiment proposes an automatic optical cable laying device for communication engineering, including a vehicle body 100. The vehicle body 100 can be made of steel material. The vehicle body 100 and the traveling bracket 210 can be formed by welding. As the laying progresses, in order to facilitate the movement of the vehicle body 100, a traveling mechanism 200 is provided at the lower part of the vehicle body 100. Before laying the optical cable, a trench needs to be excavated first. For this purpose, a trench excavation mechanism 300 is provided on one side of the vehicle body 100 (for the purpose of distinction, it can be defined as a trench excavation mechanism 300 provided on the front side of the vehicle body 100). 0, the other side is the rear side of the vehicle body 100, and in practice there is no distinction between front and back). Covering mechanisms 400 are provided on both sides and the rear side of the vehicle body 100. A driving mechanism 500 and an optical cable positioning and laying mechanism 600 are provided in sequence between the trench excavation mechanism 300 and the covering mechanism 400 on the vehicle body 100. The walking mechanism 200, the trench excavation mechanism 300 and the covering mechanism 400 are connected to the driving mechanism 500 through a linkage mechanism 700, and have a certain degree of linkage, which can reduce a part of the production cost of the equipment and facilitate its promotion and application.

[0057] The basic principle of this embodiment is as follows: the vehicle body 100 is the basic component for carrying the device, and the above-mentioned various mechanisms are installed on its upper part. The installed walking mechanism 200 can make the device move by itself under the drive mechanism 500 and the linkage mechanism 700, so as to facilitate the excavation of trenches, the laying of optical cables, etc., and then backfilling the trenches and basic compaction. The trench excavation mechanism 300 can automatically excavate the trench before laying the optical cable. The covering mechanism 400 is used to transport the soil excavated during the trench excavation process for subsequent filling of the trench. The optical cable positioning and laying mechanism 600 is used to unfold the rolled optical cable mounted on the vehicle body 100 and guide it into the interior of the trench. The trench is then filled with soil transported by the covering mechanism 400 and compacted. The entire laying process can be completed by itself, reducing a lot of manpower and improving the laying efficiency.

The walking assembly can drive the four walking wheels 220 to rotate synchronously, and the transmission assembly can drive the trench excavation mechanism 300 to move and excavate a trench on the ground. The linkage assembly is used to cooperatively drive the covering mechanism 400 to backfill the trench where the optical cable is laid. In practice, the gearbox 520 outputs The power is driven by the walking assembly to drive the walking wheel 220 at a speed not too fast, so as to provide sufficient digging time for the trench excavation mechanism 300 on the front side, and the gearbox 520 drives the output shaft of the trench excavation mechanism 300 through the transmission assembly to rotate at high speed, providing sufficient power for trench excavation. The gearbox 520 with the above functions can be equipped as needed. Through the input of the internal combustion engine or the motor, multiple output shafts with different speeds can be output, which can match the walking speed with the trench excavation progress. At the same time, the transmission speed of the covering mechanism 400 can be set to prevent soil from accumulating at the front end. These can be achieved by setting the gearbox 520.

The conveyor belt 411 at the bottom of the soil delivery troughs 410 supports and transports the soil. Once transported to the soil sliding trough 430, the soil slides down into the trench and is compacted by the ramming blocks 450, which reciprocate up and down.

[0067] Among them, the inclined plate part 421 is used to cooperate with the chain plate 380 to lift the excavated soil upward. When the soil reaches the soil guide part 422, it is dispersed into the soil feeding trough 410 on both sides and transmitted through the conveyor belt 411. The transmission shaft 713 and the synchronous belt can drive the main rollers 412 at both ends of the conveyor belt 411 to rotate, thereby driving the conveyor belt 411 to rotate, and the supporting rollers (not shown in the figure) can support the conveyor belt 411.

[0068] Replay Figure 1 and Figure 2The optical cable positioning and laying mechanism 600 in this embodiment includes a support assembly mounted on the vehicle body 100 for supporting an optical cable roller 610, a guide assembly for guiding the optical cable, and a laying assembly for laying the optical cable. The support assembly supports the optical cable roller 610, the guide assembly unwinds a single optical cable, and the laying assembly positions and lays the optical cable within the trench, allowing for immediate soil covering after laying.

[0069] Reference Figure 1 、 Figure 6-Figure 8 , wherein the support assembly includes a support frame 620 arranged on the vehicle body 100, and the top of the support frame 620 is provided with a slot 621 for supporting the optical cable roller 610; the guide assembly includes a guide block 630 arranged on the vehicle body 100, and the guide block 630 is provided with an oblique flat trumpet-shaped guide opening 631; the laying assembly includes a connecting plate 640 arranged on the guide block 630, and the connecting plate 640 has a through hole 641, and a connecting rod 650 is provided inside the through hole 641, and the connecting rod 650 is fixed to the connecting plate 640 by a fixing nut 660, and the lower end of the connecting plate 640 is provided with a laying block 670, and the bottom of the laying block 670 is provided with an arc-shaped laying groove 671.

[0070] By setting the slot 621, it is convenient to take and place the optical cable roller 610 for replacement, etc. After the optical cable passes through the guide port 631, the optical cable can be guided to the middle position of the vehicle body 100, which is the position of the groove. By adjusting the relative height of the connecting rod 650, the optical cable can be close to the bottom of the groove. The laying groove 671 on the laying block 670 can further limit the optical cable to complete the laying.

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
