[utility model content]
For addressing the above problem, the utility model provides a kind of power transmission lines overhauling driving, and this driving has simple in structure, brake apparatus applied widely, and pulley was pressed onto the maintainer on hand when this brake apparatus can prevent that driving from sliding simultaneously.
The technical solution of the utility model is as follows: a kind of power transmission lines overhauling driving; comprise by interconnective two vehicle frames that pillar consists of; respectively be provided with a pulley on two pillars; described pulley is provided with brake apparatus; described brake apparatus comprises the protective cover that covers on the pulley; form extension in the one end horizontal expansion of the bottom of described protective cover, described extension below is provided with brake(-holder) block.The maintenance driving is in sliding process, and pulley can slide along wire, presses down extension, and the brake(-holder) block and the wire friction that then are positioned at the extension below just can be braked driving.Owing to there being protective cover that pulley is covered, so pulley will block by protected cover near maintainer's hand the time, anti-limited slip wheel overwhelms on hand.
As further improvement of the utility model and optimization, can take following measure:
Respectively be provided with a framework on described two pillars, be equipped with a rotating shaft in the framework, rotating shaft is provided with pulley.
Described protective cover has comprised the support chip that is positioned at described pulley top; catch and rear catch before the two ends of support chip are provided with; described front catch and rear catch cover on respectively the both sides, front and back of pulley; the horizontal expansion of described front catch bottom forms extension; described extension below is provided with brake(-holder) block; described rear catch is provided with fixed strip, and described fixed strip is fixed on the described framework.
Described fixed strip has two to lay respectively at the left and right sides of described pulley and be fixed on the described framework.The fixed strip of pulley bilateral can more firmly be fixed on protective cover on the described framework.
Described support chip is fixed on the described framework, can stablize being connected between protective cover and the framework, avoids protective cover to rock when driving slides.
Described front catch is provided with the brake(-holder) block that stretches to pulley.Brake(-holder) block on the front catch produces friction with pulley when being pressed towards pulley, can brake driving equally.
Connect a connecting rod between described front catch and the rear catch, an end of connecting rod is fixed on the rear catch, and the other end of connecting rod passes front catch and is slidingly connected.Connecting rod can keep the shape of protective cover, prevents that it from staying.
Be set with a Compress Spring on the described connecting rod, an end of described Compress Spring is fixed on the connecting rod, and the other end is against on the front catch.Under the effect of Compress Spring, the front catch that is pressed down is easy to resilience.
The material of described protective cover is steel.The employing steel are that the protective cover of material possesses enough intensity and elasticity.
Compared with prior art, outstanding advantages of the present utility model is: adopt the protective cover that installs the band brake sheet at the driving pulley additional, not only can play the effect of braking driving, and can prevent that limited slip wheel is pressed onto maintainer's hand when sliding; The utility model is simple in structure, operates simple and easyly, with low cost, goes for all with the maintenance driving of pulley.
