Description
Technical field
The present invention relates to a kind of equipment for coaster, specifically, relate to a kind of double-row type pulley sheave.
Background technology
At present, in order to ensure high pressure and ehv power transmission engineering and the safe operation of power transmission and transformation thereof, it is necessary to using Transmission Towers, the erection spacing of these steel towers is usually 200 to 400 meters, and the height of the power transmission and transformation line being erected on steel tower is many at 40 to 80 meters.In order to these power transmission and transformation lines are overhauled and safeguard, many use transmission line of electricity coasters, existing coaster many employings single row type pulley, it is hung on power transmission and transformation line, by surface personnel's pulling motion, but there is, during using, the danger come off in this single row type pulley, is easily separated from power transmission and transformation line if running into acutely to rock.
In order to solve with present on problem, people are seeking a kind of preferably technical solution always.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, thus provide a kind of design science, rational in infrastructure, use simple and that slip-off preventing is effective double-row type pulley sheave.
To achieve these goals, the technical solution adopted in the present invention is: a kind of double-row type pulley sheave, it includes fixed pulley seat and the movable pulley seat being fixed on described fixed pulley seat, described fixed pulley seat is parallel with described movable pulley seat antarafacial, wherein, it is provided with fixed pulley in described fixed pulley seat, in described movable pulley seat, movable pulley is installed, it is respectively arranged with sliding tray on two side shields of described movable pulley seat, the wheel shaft of described movable pulley is arranged in described sliding tray, the two ends of described wheel shaft are provided with screw thread, described movable pulley is fixed with described movable pulley seat by nut；This double-row type pulley sheave is arranged on the vehicle frame of transmission line of electricity coaster, during use, first described movable pulley is pulled down, then the fixed pulley in this double-row type pulley sheave is mounted on the upper limb of power transmission and transformation line, after mounting, described movable pulley is loaded in described sliding tray, described movable pulley is fastened on the lower edge of described power transmission and transformation line, is then fixed by nut, and power transmission and transformation line clamped jointly by described fixed pulley and described movable pulley, ensure transmission line of electricity coaster in the course of the work, do not come off.
Based on above-mentioned, described fixed pulley seat top is provided with link.
Based on above-mentioned, the rubbing surface of described fixed pulley and the rubbing surface of described movable pulley are arcs of recesses.
Hinge structure of the present invention has prominent substantive distinguishing features and marked improvement, specifically, the present invention is different from original pulley sheave, it uses double-row type structure to include fixed pulley seat and the movable pulley seat being fixed on described fixed pulley seat, it is provided with fixed pulley in described fixed pulley seat, in described movable pulley seat, movable pulley is installed, during use, first fixed pulley is placed in the upper limb of power transmission and transformation line, then described movable pulley is installed, movable pulley is made to be arranged on the lower edge of power transmission and transformation line, described fixed pulley and described movable pulley block power transmission and transformation line jointly, this double-row type pulley sheave can not be come off, it has design science, rational in infrastructure, use simple and that slip-off preventing is effective advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
