specific Embodiment approach 1

[0005] Specific embodiment one: (referring to Fig. 1~3) this embodiment is made up of ditching shovel 2, two optical cable slot plates 3, slot plate cover 4, guide wheel 6, guide wheel shaft 7; The connecting hole 1 and the front end of the ditching shovel 2 are provided with a soil dividing blade 9, two optical cable slot plates 3 are respectively fixed on the left and right sides of the rear side of the ditching shovel 2, and the slot cover plate 4 is fixed on the two optical cable slot plates 3 On the rear end of the two optical cable troughs 3, the lower rear ends are provided with circular arc projections 14, and the two ends of the guide wheel shaft 7 are arranged on the two optical cable troughs 3 at the circular arc projections 14, and the guide wheels 6 Set on the guide wheel shaft 7 between the two optical cable troughs 3, the upper channel 10 of the optical cable is formed between the two optical cable troughs 3 on the upper side of the guide wheels 6, the trenching ...

specific Embodiment approach 2

[0006] Specific embodiment two: (referring to Fig. 1, Fig. 2) the groove cover plate 4 of this embodiment is provided with a protrusion 16 towards the side of the ditching shovel 2, and the protrusion 16 of the groove cover plate 4 is arranged on two optical cable groove plates 3 On the rear side between them, the slot cover plate 4 is fixed on the two optical cable slot plates 3 by bolts 5 . The slot cover plate 4 of this embodiment is a detachable structure. In case of mechanical failure, the slot cover plate and guide wheels can be removed to leave the optical cable to facilitate mechanical maintenance.

specific Embodiment approach 3

[0007] Embodiment 3: (see FIG. 1 and FIG. 3 ) The difference between this embodiment and Embodiment 1 is that a pressure plate 8 is added to the lower ends of the two optical cable trays 3 . Other compositions and connections are the same as in the first embodiment. The effect of the increased pressing plate 8 is that when the ditch is opened with a shovel, some sharp stones may be tilted upwards, which affects the laying quality of the optical cable. At this time, the pressing plate 8 can flatten or crush the sharp stones.

Abstract

The ditching and laying device for buried optical cable as one kind of optical cable burying deice can ditch, lay optical cable and refill soil. The ditching shovel of the present invention has connecting holes in the upper part, cover plate fixed on the back end of two optical cable groove plates, and guide wheel set on the guide wheel shaft between the two optical cable groove plates. The two optical cable groove plates, the ditching shovel and the cover plate form the upper optical cable channel, and the connecting holes are connected to the soil loosening shovel of bulldozer for ditching and laying optical cable. The ditching and laying device of the present invention has fast optical cable laying efficiency.

Description

technical field [0001] The invention relates to an underground device for optical cables. Background technique [0002] The construction of existing optical cables generally adopts the method of underground burying, without overhead equipment, and has good concealment, which not only saves money but also is safe and reliable. At present, laying optical cables is mainly done by manual trenching, laying, and backfilling. The disadvantages are high labor intensity, slow laying progress, low work efficiency, and a large proportion of labor costs. In case of complex soil conditions, the construction progress will be slower. The patent number is ZL01247138, the authorized announcement date is June 9, 2002, and the utility model patent named "automatic trenching machine for buried engineering" discloses a kind of trenching machine for optical cable trenches, cable trenches and small pipeline buried trenches. dig. Although this ditching machine is faster and more efficient than m...
