Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0038] The main technical problem to be solved in this embodiment: During the laying of optical cables in the prior art, separate trenching is required. After the optical cable is manually pulled into the trench, simple fixation is also needed, and then backfilling is carried out, resulting in high labor intensity and low laying construction efficiency.

[0039] Therefore, the main inventive concept of this embodiment is as follows. According to the existing construction steps: excavating a trench, laying an optical cable, and backfilling the trench, the above-mentioned multiple steps are integrated on one device. That is, through this embodiment, the above-mentioned optical cable laying steps can be completed at one time, reducing the human participation, lowering the labor intensity, and improving the laying efficiency. At the same time, considering the overall structural linkage, the equipment cost is minimized as much as possible, which is more conducive to practical promotion and use. For details, refer to the following embodiments.

[0040] However, although the following embodiments mention the laying of optical cables, it can be imagined that this device is also applicable to the laying of materials such as cables and flexible pipes. There are no excessive restrictions here.

[0041] As Figures 1-8 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 materials. The vehicle body 100 and the walking support 210 can be formed by welding. As the laying progresses, in order to facilitate the walking of the vehicle body 100, a walking mechanism 200 is provided at the lower part of the vehicle body 100. Before laying the optical cable, it is necessary to first excavate a trench. Therefore, a trench excavation mechanism 300 is provided on one side of the vehicle body 100 (for the sake of distinction, it can be defined that the trench excavation mechanism 300 is provided on the front side of the vehicle body 100, and the other side is the rear side of the vehicle body 100. In practice, there is no distinction between the front and the rear). Soil 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 successively provided between the trench excavation mechanism 300 and the soil covering mechanism 400 on the vehicle body 100. The walking mechanism 200, the trench excavation mechanism 300, and the soil covering mechanism 400 are connected to the driving mechanism 500 through a linkage mechanism 700, having a certain degree of linkage. In this way, a part of the production cost of this equipment can be reduced, which is conducive to promotion and application.

[0042] Basic principle of this embodiment: The vehicle body 100 is the basic component for carrying this device. The above-mentioned various mechanisms are installed on its upper part. Among them, the installed traveling mechanism 200 can make this device travel by itself under the drive of the drive mechanism 500 and the linkage mechanism 700, so as to facilitate trenching and following the laying of optical cables, etc. Then, the trench is backfilled and basically compacted. The trench excavation mechanism 300 can automatically excavate the trench before laying the optical cable. The soil covering mechanism 400 is used to convey the soil dug out during the trench excavation process for subsequent filling of the trench. The optical cable positioning and laying mechanism 600 is used to unroll the coiled optical cable installed on the vehicle body 100 and guide it into the trench. Then, the trench is filled with the soil conveyed by the soil covering mechanism 400 and compacted. The entire laying process can be completed automatically, saving a large amount of manpower and improving the laying efficiency.

[0043] Refer to Figures 1-3 , specifically, the traveling mechanism 200 in this embodiment includes traveling brackets 210 arranged on the lower side of the vehicle body 100. There are four traveling brackets 210, with two traveling brackets 210 arranged on each side of the vehicle body 100, one group at the front side of the vehicle body 100 and one group at the middle and rear side of the vehicle body 100. A traveling wheel 220 is rotatably connected to each traveling bracket 210. The traveling wheels 220 are divided into two groups, front and rear. The trench excavation mechanism 300 is arranged at the middle position of the front side of the vehicle body 100, between the two traveling wheels 220. When traveling, the traveling wheels 220 are on both sides of the trench, belonging to straddle-type traveling, which is also convenient for subsequent optical cable laying. The traveling wheels 220 can be driven by the drive mechanism 500 and the linkage mechanism 700 to drive the vehicle body 100 to gradually move forward, gradually excavate the trench, lay the optical cable along with the vehicle, and cover and compact the soil.

[0044] Refer to Figure 1 and Figure 3 , in which the drive mechanism 500 includes an internal combustion engine or a motor 510 arranged on the upper side of the vehicle body 100. The internal combustion engine or the motor 510 is drivingly connected to a gearbox 520 arranged on the upper side of the vehicle body 100. The internal combustion engine has great power and is suitable for excavating deeper trenches. The motor can be applied in the case where the depth and width of the trench excavation are not large. By connecting to the gearbox 520, the gearbox 520 can output power to different mechanisms through speed change to drive each mechanism to cooperate, which can save the investment in other power components and thus reduce the production cost of this equipment.

[0045] Refer to Figure 2 and Figure 3, in this embodiment, the linkage mechanism 700 includes a traveling assembly for driving the rotation of the traveling wheels 220, a transmission assembly for driving the trench excavation mechanism 300, and a linkage assembly for driving the soil covering mechanism 400. The traveling assembly is drivingly connected to the gearbox 520, and the transmission assembly is in transmission connection with the gearbox 520. The traveling assembly can drive the four traveling wheels 220 to rotate synchronously. The transmission assembly can drive the trench excavation mechanism 300 to operate and excavate a trench on the ground. The linkage assembly is used to coordinately drive the soil covering mechanism 400 to operate and backfill the trench where the optical cable has been laid. In practice, the power output by the gearbox 520 drives the traveling speed of the traveling wheels 220 through the traveling assembly not to be too fast, providing sufficient time for the trench excavation mechanism 300 at the front side to dig the trench. And the output shaft of the trench excavation mechanism 300 driven by the gearbox 520 through the transmission assembly can rotate at a high speed, providing sufficient power for excavating the trench. The gearbox 520 with the above functions can be equipped as needed. Through the input of an internal combustion engine or an electric motor, multiple output shafts with different rotational speeds can be output, which can match the traveling speed and the trench excavation progress. At the same time, the conveying speed of the soil covering mechanism 400 can be set to prevent soil from accumulating at the front end. These can be achieved by using the set gearbox 520.

[0046] Specifically, the traveling assembly includes two sets, a total of four half shafts 710, the half shafts 710 are connected to the drive axle housing 711, and the two drive axle housings 711 are drivingly connected through the middle shaft 712. The drive axle housing 711 is drivingly connected to the gearbox 520 through the power shaft 720. The linkage assembly is drivingly connected to the drive axle housing 711. A total of four half shafts 710 are provided, and each half shaft 710 is connected to a traveling wheel 220. The gearbox 520 transmits power to the drive axle housing 711, and the drive axle housing 711 can drive the traveling wheel 220 to rotate through the half shaft 710, so that the vehicle body 100 moves. Through the drive axle housing 711, the linkage assembly can be driven to operate, so as to drive the soil covering mechanism 400 to operate and convey the soil excavated from the trench to the rear end of the vehicle body 100 to fill the trench.

[0047] Refer to Figures 1-4 , in this embodiment, the trench excavation mechanism 300 includes a trench excavation component rotatably arranged on the vehicle body 100 and an adjustment component for adjusting the trench excavation depth of the trench excavation component. The trench excavation component is drivingly connected to the transmission component.

The transmission component is used to drive the trench excavation component to operate and excavate the trench.

[0048] Refer to Figures 1-4, specifically, the adjusting assembly includes an adjusting plate 310 connected to the vehicle body 100.

[0049] The excavation depth of the trench is adjustable by the adjusting assembly. The specific adjusting method is as follows: The adjusting screw 330 is provided with an external thread. The adjusting nut 340 is threadedly connected to the adjusting screw 330. First, loosen the adjusting nut 340, adjust the position of the adjusting screw 330. After adjustment, the adjusting screw 330 can be locked by the adjusting nut 340 to adjust the excavation depth of the trench. The fork frame 350 is used to rotatably connect the driven rotating shaft 370. An output shaft can be provided on the gearbox 520. The output shaft drives the driving rotating shaft 360 to rotate through a synchronous belt or a chain, so that the chain plate 380 sleeved between the driving rotating shaft 360 and the driven rotating shaft 370 rotates cyclically. The grooving knives 390 on the chain plate 380 can dig the soil to form a trench. The excavated soil is received by the soil covering mechanism 400 and conveyed to the rear end of the vehicle body 100 to prepare for covering the trench where the optical cable has been laid well and backfilling.

[0050] Refer to Figures 1-4 , in order to make the soil generated by excavating the trench be filled into the trench where the optical cable has been laid as much as possible and prevent excessive covering of both sides of the trench. For example, in places with lawns, a larger area of lawn may be covered and manual cleaning is still required.

Two groups of the soil conveying components are provided and are respectively arranged on both sides of the chain plate 380. It also includes a soil ramming component arranged at the end of the vehicle body 100. The soil conveying component is used to collect the soil generated by excavating the trench and convey it to the rear end of the vehicle body 100 for filling the trench.
