Abstract
The present utility model discloses a pulley for erecting a power transmission line. The pulley comprises a U-type frame, and an upper pivot and a lower pivot arranged inside the U-type frame in parallel, rotating wheels are arranged on the upper pivot and the lower pivot, one end of the lower pivot is a hollow sleeve, a spring and a pin axle are successively arranged inside the sleeve from a phase pivot center to the end part, a positioning mechanism is arranged between the pin axle and the sleeve, the pin axle passes through the U-type frame and is fixed on the U-type frame through a pin, and a suspension ring which can be rotated in a radial way is arranged on the top part of the U-type frame. In the pulley for erecting the power transmission line, two rotating wheels are adopted to restrict the position of a power transmission conducting wire, rolling friction between the power transmission conducting wire and an oil wheel can be realized in any case, the suspension ring can be rotated at random in the radial direction, thus, using the pulley to draw the power transmission conducting wire is labor-saving, and the phenomenon that a leading rope of the conducting wire is twined can be avoided.
Description
Technical field
Used pulley gear when the utility model erects power transmission lines wire.
Background technology
In the prior art, set up or dismantle transmission pressure and usually adopt the guiding that is installed between adjacent two steel towers strong and be suspended on the guide rope and by the pulley of backguy control, and for avoid transmission pressure and ground or and two steel towers between the quilts such as electrified body, crops, trees, river, road, building and the structures contacted crossing frame of barrier and the net that insulate crossed over.Because the transmission pressure that need to set up or be removed is under the traction of pulley, to between adjacent two steel towers, move, because of guide rope and pulley, and backguy is subject to wind action in the air at height, can cause pulley to reverse, if pulley can not automatically be adjusted direction, wrapping phenomena appears in guide rope and wiring meeting after pulley reverses.After this phenomenon occured, the transmission pressure on the mobile pulley was very difficult, particularly in the situation that the pulley windup-degree is larger, can cause the guide wire wide-angle to twine and wearing and tearing, also was difficult to simultaneously the traction transmission pressure.On the other hand; because of in the process of traction transmission pressure; jumping can appear on pulley in transmission pressure often or passive type ground moves; and this move mode can increase tractive resistance equally; even pulley is not in the situation that twist; its tractive resistance also is very large, brings certain difficulty to normal construction.Present pulley, its structure is to be made of link plate, support and two rack-mount pulleys, transmission pressure rolls between two pulleys, reduced frictional resistance, but owing to being to be fixedly connected with between link plate and the support, and two pulley be fixed on the support, one end of transmission pressure can only pass from the gap between two pulleys, and can not ensure and partly to be placed on wire between two pulleys from the centre under any operating mode, be can not neatly transmission pressure be taken off or put between two pulleys in the work progress, operation brings difficulty to stringing.
Summary of the invention
The purpose of this utility model is to overcome the pulley that above-mentioned deficiency provides a kind of usefulness that erects power transmission lines.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pulley of the usefulness that erects power transmission lines, comprise U-shaped frame and be contained in side by side U-shaped frame interior head lamp brush guard pivot and lower pivot, on head lamp brush guard pivot and the lower pivot moving runner is installed, one end of lower pivot is the sleeve of hollow, be disposed with spring and bearing pin by mind-set end in the phase pivot in sleeve, be provided with detent mechanism between bearing pin and the sleeve, bearing pin passes U-shaped frame, and be fixed on the U-shaped frame by pin, but be provided with the suspension ring of radial rotating at the top of U-shaped frame.
The pulley of the above-mentioned usefulness that erects power transmission lines, described detent mechanism is to be provided with reference column at bearing pin, is embedded with location notch on sleeve corresponding to reference column, reference column can slide in location notch.
The pulley of the above-mentioned usefulness that erects power transmission lines, described detent mechanism is to be embedded with location notch at bearing pin, is provided with reference column on sleeve corresponding to location notch, reference column can slide in location notch.
Adopt technique scheme, the utility model has following advantage: during use, at first will take off pin, press bearing pin, lower pivot will be taken off from U-shaped frame, after being installed in transmission pressure between two moving runners, bearing pin with lower pivot end inserts in the hole of U-shaped frame again, and under the effect of spring, bearing pin passes U-shaped frame and stretches out outside the U-shaped frame, insert with pin in the pin-and-hole of bearing pin, lower pivot is fixed.The erect power transmission lines pulley of usefulness of the utility model adopts two moving runners to limit the position of transmission pressure, and make transmission pressure under any circumstance all and between oil tanker realize rolling friction, and suspension ring radially can arbitrarily rotate, so, utilizing this pulley to draw transmission pressure can be laborsaving, can not make again the wire messenger that the phenomenon of twining occurs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Fig. 1 is the structural representation of lower pivot.
Embodiment
The pulley of a kind of usefulness that erects power transmission lines as depicted in figs. 1 and 2, comprise U-shaped frame 1 and be contained in side by side U-shaped frame interior head lamp brush guard pivot 2 and lower pivot 3, on head lamp brush guard pivot 2 and the lower pivot 3 moving runner 4 is installed, one end of lower pivot 3 is sleeves 5 of hollow, in sleeve 5, overlapped successively to the end by pivot center and be provided with spring 6 and bearing pin 7, be provided with detent mechanism between bearing pin 7 and the sleeve 5, bearing pin 7 passes U-shaped frame 1, pin 8 inserts in the pin-and-hole of bearing pin, by pin 8 bearing pin is fixed on the U-shaped frame 1, but is provided with the suspension ring 9 of radial rotating at the top of U-shaped frame 1.
Detent mechanism of the present utility model can be to be provided with reference column at bearing pin, is embedded with location notch on sleeve corresponding to reference column, and reference column can slide in location notch.
Detent mechanism of the present utility model can also be to be embedded with location notch at bearing pin, is provided with reference column on sleeve corresponding to location notch, and reference column can slide in location notch.
When using like this, at first will take off pin, press bearing pin, lower pivot taken off from U-shaped frame, be installed in transmission pressure between two moving runners after, bearing pin with lower pivot end inserts in the hole of U-shaped frame again, under the effect of spring, bearing pin passes U-shaped frame and stretches out outside the U-shaped frame, inserts with pin in the pin-and-hole of bearing pin, lower pivot is fixed in the U-shaped frame, and transmission pressure just slides between two moving runners like this.
