Abstract

The utility model discloses an underground optical cable laying apparatus without ditching which belongs to the working appliance of for the underground optical cable laying. The working face which bends backward in the front of the underground optical cable laying apparatus without ditching is provided with a serration tooth with cutting edge. A ditching blade is arranged on the lower part of the front side of the laying apparatus, and is positioned under the serration tooth. The lowest position of the ditching blade is below the lowest position of the main body of the laying apparatus. The utility model has the advantages of simple structure, reliable working, high efficiency, low working resistance, low dynamic force consumption, energy saving, low working cost and good working quality.

Description

Exempt from the underground optical cable laying device of ditching

Technical field

The utility model belongs to optical cable provided underground operating apparatus.

Background technology

At present, when long distance is laid optical cable, cable construction on field and wilderness, all adopt artificial or excavation machinery excavation open drain groove after the cable of giving out light on the channel bottom upper berth, return again and add sandy soil and bury real process, obviously, engineering quantity is big, cost is high, operating efficiency is low, labour intensity is its outstanding shortcoming and problem greatly; And, can only establish optical cable on same degree of depth aspect upper berth behind the excavation open drain groove, if when requiring to bury optical cable underground on the three-dimensional depth different levels, engineering quantity increases considerably again, efficient is lower, and is difficult to guarantee the laying quality requirement.The applicant developed a kind of underground optical cable laying device of ditching of exempting from, need not to excavate the open drain during the underground optical cable of this laying device lay can directly be embedded in the optical cable shop under the ground surface and require the degree of depth, and realize the synchronous laying of stereoscopic multi-layer different depth optical cable, have simple in structure, with low cost, fault is few, operation is reliable, efficient is high, the scope of application is wide, adaptable characteristics.But because the deficiency on its structure design during this laying device ditching and laying optical cable operation, adopts squash type trench digging mode, operation resistance is big, power consumption is its outstanding shortcoming greatly, even influence trench digging and optical cable lay operation quality.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at prior art, design provides a kind of novel underground optical cable laying device of ditching of exempting from, by adopting the sawtooth tooth to cooperate the structure design of ditching knife, reach the purpose that reduces the ditching operation resistance significantly, reduces power consumption, energy conservation.

Basic design of the present utility model is, be provided with the sawtooth tooth of cutting edge in the crooked position place backward in laying device main body front side scope of operation integral body, ditching knife fits on the preceding side lower part of laying device main body admittedly, be positioned at sawtooth tooth below, the extreme lower position of its ditching knife is under the laying device main body extreme lower position, constitutes to exempt from the underground optical cable laying device of ditching.

The utility model is simple in structure, and operation is reliable, efficient height, the characteristics that have especially that the ditching and laying operation resistance is little, power consumption is little, save the energy, operating cost are low, operation quality is good.

Description of drawings

Accompanying drawing is to exempt from the underground optical cable laying device of ditching general structure schematic diagram.

Piece number explanation among the figure:

1, laying device main body, 2, sawtooth tooth, 3, ditching knife, 4, the curved seat of optical cable outlet, 5, optical cable through hole.

The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of underground optical cable laying device of ditching of exempting from, on laying device main body 1, be provided with the optical cable through hole 5 that communicates to lower end from the upper surface, the curved seat 4 of optical cable outlet fits on the rear side middle part of laying device main body 1 admittedly, and be connected with optical cable through hole 5, be provided with the sawtooth tooth 2 of cutting edge in the crooked position place backward in laying device main body 1 front side scope of operation integral body; Ditching knife 3 fits on the laying device main body 1 preceding side lower part admittedly, is positioned at sawtooth tooth 2 belows, and the extreme lower position of its ditching knife 3 is under laying device main body 1 extreme lower position.

When operation is used, to exempt from the underground optical cable laying device configuration of ditching and be installed in traction power mechanically, pass in optical cable the to be laid optical cable through hole 5 on the laying device main body 1, starting end is pulled out (if need layer stereo to lay, the optical cable on upper strata is pulled out from the curved seat 4 of optical cable outlet successively) from the lower end of optical cable through hole 5; Dig a heatable adobe sleeping platform up and down on the ground of laying starting point, the underground optical cable laying device of ditching of exempting from of putting on optical cable is placed in the hole by hitching machinery control, reach the lay degree of depth, hitching machinery drives the optical cable laying device and forwards moves, sawtooth tooth 2 cutting edges of laying device main body 1 and 3 common cooperations of ditching knife cut out the fillet slit with soil, optical cable is laid in the fillet slit, and a small amount of backfill automatically, finish underground optical cable and lay operation.Sawtooth tooth 2 adopts saw cut principle cutting soil, helps soil and flows, and reaches purpose that reduces the cutting resistance and the effect of saving power consumption.

Claims

A kind of underground optical cable laying device of ditching of exempting from, on laying device main body (1), be provided with the optical cable through hole (5) that communicates to lower end from the upper surface, the optical cable curved seat of outlet (4) fits on the rear side middle part of laying device main body (1) admittedly, and be connected with optical cable through hole (5), it is characterized in that being provided with the sawtooth tooth (2) of cutting edge in the crooked position place backward in laying device main body (1) front side scope of operation integral body; Ditching knife (3) fits on the preceding side lower part of laying device main body (1) admittedly, is positioned at sawtooth tooth (2) below, and the extreme lower position of its ditching knife (3) is under laying device main body (1) extreme lower position.
