Abstract
The invention provides a huge mountain area high-voltage power cable laying method and a steering pulley device. The laying method comprises the following steps: the step 1) arranging one steering pulley device every a certain distance on a line where power cables need to be laid in the mountain area environment; the step 2) pulling the power cables to be laid out of a cable reel; the step 3) enabling the pulled-out power cables to pass around the steering pulley device; the step 4) pulling the power cables to the next steering pulley device by utilizing a traction device or labor dragging; and the step 5) when the power cables are arranged to the designated places, fixing the cables, and thus cable laying is finished. The steering pulley device comprises a main body and steering heads. The main body is of a steel tube structure, of which the length is fixed; and the steering heads are arranged at the two ends of the body. Each steering head comprises a framework formed by bending and welding of steel bars. The front end of the framework is provided with a plurality of bearings; and the back end of the framework is provided with a hold hoop through welding.
Description
Technical field
The present invention relates to power cable layer field, be specifically related to a kind of Mountainous region high voltage power cable laying method and deflection sheave device.
Background technology
Along with the develop rapidly of domestic economy, the scope that national grid covers is also increasing, and much remote area can have access to electricity.The layout that power supply engineering be can't do without needing to carry out electrical network extends, and in more remote mountain area, needs to lay high voltage power cable to another mountain top from a mountain top.But because height slope, mountain is steep, difference in height is larger, but also often need the geographical conditions of passing through many places sky way.Traditional laying method is in place after direct employing is manually laid again, and needs to use at least 300 manually could normally lay out from cable hank by high voltage power cable at those Mountainous region Special zone, and overall shoulder is lifted and is transported to desired location placement.Because Mountainous region is with a varied topography, from mountain on mountain, from this mountain top to another mountain top, workmen is numerous, management exists blind area, communication inconvenience, inconvenience commander, easily cause potential safety hazard while efficiency is low, and easily damage cable.
Summary of the invention
For solving the problems of the technologies described above, defects such as having the object of the present invention is to provide a kind of method that high efficiency high voltage power cable being applicable to Mountainous region Special zone construction requirement lays, existing power cable layer method wastes time and energy to solve, danger coefficient is high.
For achieving the above object, a kind of Mountainous region high voltage power cable laying method of the present invention and deflection sheave device, it is characterized in that: described laying method is, Step1. needs the route of power cable laying arranges a deflection sheave device every a segment distance in the environment of mountain area; Step2. will treat that power cable laying pulls out from cable hank; Step3. the power cable of pull-out is passed deflection sheave device; Step4. utilize draw-gear or manpower to pull and move power cable to next place's deflection sheave device, and then by power cable through deflection sheave device; Step5. repeat Step4 until power cable is arranged into assigned address always, after being fixed by cable, namely complete laying of cable;
Described angle pulley device comprises main body and steering head, and described main body is the steel tubular structure of regular length; Described steering head is arranged on the two ends of body, and described steering head comprises the shaping framework of reinforcing bar bent jointing; Described frame front end is provided with some bearings, and described bearing is not in contact with each other; Described back-end framework is provided with anchor ear by welding, and described anchor ear comprises the iron plate of two panels " Ω " type, and described anchor ear " Ω " sections plate two ends offer through hole, are provided with fastening bolt in described through hole.
Further, described some bearings form a regular polygon in a plane, and being convenient to intrinsic power cable can multi-directionly slide.
Further, described frame front end bearing is roller bearing, and described bearing two ends are provided with seal cover, prevents the foreign material such as construction environment and natural earth, rainwater from affecting the working life of bearing.
Further, the position of described steering head anchor ear inwall and the corresponding steering head of body outer wall all forms anti-slip veins, makes anchor ear can be fixed on body two ends tightly by fastening bolt.
The present invention compared with prior art; its beneficial effect is: a kind of Mountainous region high voltage power cable laying method that the present invention proposes; by the body that cable rises through angle pulley; utilize and respectively fill at the body two ends of tubulose the steering head that is provided with multiple bearing; cable can be protected can not to be scraped off in the process of transfer slip; also save a large amount of manpower, ensure that the safety that workmen works in the mountain area of circumstance complication.

Fig. 1 is front view of the present invention;
Fig. 2 is left view of the present invention.
Figure number and title: 1, roller bearing, 2, steel bar framework, 3, anchor ear, 4, body.
Embodiment
By describe in detail the present invention technology contents, structural feature, reached object and effect, hereby exemplify embodiment below and coordinate accompanying drawing to be explained in detail.
In describing the invention, it will be appreciated that, term " center ", " longitudinally ", " laterally ", " front ", " after ", " left ", " right ", " vertically ", " level ", " top ", " end ", " in ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore limiting the scope of the invention can not be interpreted as.
Refer to shown in Fig. 1; and shown in composition graphs 2; the invention provides a kind of Mountainous region high voltage power cable laying method; a deflection sheave device is fixed every a segment distance or preposition in Mountainous region; by power cable the to be laid tubular body 4 through pulley gear; then by pulling equipment or manpower, cable dragging is passed its tubular body 4 to the pulley gear of everywhere; because be all equipped with the steering head that bearing 1 is formed for main body in the both sides of body; both protected cable not scratched by the mouth of pipe, and had and cable can be allowed to turn to freely, slide.Do not need manually to lay out from cable hank by high voltage power cable, overall shoulder is lifted and is transported to desired location, ensures that the job safety of workmen saves a large amount of manpowers simultaneously.
In sum, be only the preferred embodiment of the present invention, do not limit protection scope of the present invention with this, all equivalence changes done according to the scope of the claims of the present invention and description with modify, be all within scope that patent of the present invention contains.
